Description
The present invention relates to a tan system comprising a tan and a fastening arrangement. Further, the present invention relates to a fastening arrangement.
Background
When drying skins, such as mink or fox skins, after peeling and scraping the layer of grease on the leather side of the skin, the skins are typically stretched on a tan, which is often provided with a fat-absorbing material to remove the remaining grease on the leather side of the skin. pelt. The use of tans in connection with the drying of skins is well known in the art and a large number of configurations of such tans have been developed in the past. A standard has also been established for skin sizes and thus also for tans.
The most widespread tans have previously been made of wood, and can be briefly described as a flat piece of wood which defines a longitudinal direction and which in the longitudinal direction has a first wide side surface, a second wide side surface, a first narrow side surface and a second narrow side surface. One end of the tan, the bottom end, is cut at a right angle to the longitudinal direction. The lower end adjacent the bottom has a constant width which is gradually reduced towards a tapered and rounded end towards the top end of the tan. Such tans typically also have a longitudinal slot to allow air to pass.
The drying procedure for the fur is to be understood to be a drying out of the leather side of the fur to such an extent that, from experience, it prevents any attack on the fur by mites. The drying process is typically effected by blowing dry air into the slit of the tan via tubes introduced into the slit, where, via perforations in the walls of the tan, the dry air diffuses out onto the leather side of the skin and dries the skin.
From WO 01/62985 a bag-shaped casing is known as a holding bag which is used to hold the skin on a tan during the drying process. The holding bag is pulled over the tan with the stretched skin from the skull end of the skin so that the fur side of the skin is in close contact with the fur, resulting in the skin being pressed against the tan
DK 2020 00014 U1 with a force sufficient for the skin to remain substantially in the stretched position during drying.
Further prior art includes US 3,137,963 wherein a tan comprising a flat sheet metal sheet with perforations therein and lateral beads is disclosed.
WO 2005/026394 discloses a tane which can be locked in a position in which it has a first circumference and which may also occupy a position in which it has a second circumference which is smaller than the first circumference by displacing opposing halves in relation to each other. This results in a significantly easier removal of the skin from the tan.
US 1,110,016 relates to a tane having a pair of longitudinal legs and a nose piece located therebetween.
US 3,526,967 relates to a skin drying system comprising an air conditioning unit for supplying temperature controlled air to a plurality of manifolds with nozzles on which skin dryer frames are arranged.
WO 82/03634 relates to a non-absorbent plastic tan having several ducts near its edges to supply drying air to the edges of the tan so that the skin dries uniformly and adheres less frequently to the tan.
US 3,303,038 relates to a leather dryer frame comprising opposing side bars connected by a nose over which a leather frame can be pulled and held tightly.
DK 2012 70519 A1 relates to a tane with a lower part and an upper part. The lower portion has an outer cross-sectional circumference which is substantially constant and the upper portion has an outer cross-section which is gradually reduced.
DK 2013 00091 U4 relates to a tane with a lower part and an upper part. The lower portion has an outer cross-sectional circumference which is substantially constant and the upper portion has an outer cross-section which is gradually reduced. The lower part extends between 36 cm and 50 cm.
DK 177480 B1 describes a tane with two wide elongated side surfaces. The tan includes expansion members which define a narrow elongated side surface extending between
DK 2020 00014 U1 side edges of the wide side surfaces. The expansion members are movable between an expanded position and a non-expanded position.
Some of the aforementioned tans have an outer circumference consisting of opposing, non-moving surfaces and opposing moving surfaces. Thus, tans with this variable circumference for simplifying the removal of the skin after drying are known in the art. Thus, tans are expanded during the drying process. Since the skins are fixed firmly during drying and may shrink slightly, the skins may be difficult to remove from the tans. Further, the skins are typically fixed in a stretched state, which increases the pressure of the skin against the tan. By reducing the circumference of the tan, the skin will be easier to remove from the tan.
However, the tans that have been used so far have only a limited variation in circumference, with only a limited portion of the circumferential surfaces being movable / reducible. Typically, the prior art tans have two opposed surfaces which are movable relative to each other, and thus, opposing faces or portions of the circumference which are non-movable relative to each other may still exist. Although, according to the prior art, the tan can change the total circumference and thereby loosen the skin, it is noted by the applicant that in certain circumstances the skin can still adhere relatively strongly to the tan at those positions of the tan where the surface or perimeter has not become reduced.
Accordingly, it is an object of the present invention to provide technologies to simplify the removal of the skins from the tans and to avoid the situations where the skins can adhere to the tan due to drying and stretching, while at the same time ensuring that the tan retains a substantially elliptical circumference in order to distribute the inwardly oriented feature of the skin uniformly over the tan.
It is an advantage of the present invention that the tan can be locked in the expanded position and that the movement between the expanded position and the reduced position can be performed very accurately using low force.
It is a feature of the present invention that the tan can be modified to receive skins of various sizes and shapes.

DK 2020 00014 U1
The tuna according to the first and second aspects of nutritious production must have a total size suitable for receiving a fur from an animal, such as a mink or fox. The web according to the first and second aspects of the present invention typically has a substantially elliptical cylindrical shape which is tapered in the longitudinal direction. The skin is applied to the tan in accordance with the first and second aspects of the present invention by pulling it on the tan in accordance with the first and second aspects of this generation in the longitudinal direction, while the tan according to the first and second aspects of the present invention takes up its expanded condition. It is to be understood that known skin bags may be used between the skin and the tan in accordance with the first and second aspects of the present invention, for the purpose of removing fatty substances from the skin. The wall elements may be arcuate, which in connection with wall elements should be understood to mean that the outer surfaces of the respective wall elements of the tan, in accordance with the first and second aspects of the present invention, have a convex shape. The wall elements typically comprise a large number of holes or nozzles to allow ventilation air to pass from the cavity inside the tan in accordance with the first and second aspects of the present invention to the environment through the skin.
The first, second, third and fourth wall elements together define the substantially elliptical outer circumference of the tan in accordance with the first and second aspects of the present invention suitable for and adapted to receive an animal's skin via its respective outward oriented surfaces.
The inwardly oriented surfaces may preferably define a concave shape, which together define the cavity of the tan in accordance with the first and second aspects of the present invention. The wall elements are typically made of plastic. The wall elements are further defined in the circumferential direction by longitudinal edges.
The elongate core member located in the cavity is movable in the longitudinal direction relative to the wall members. The actuating elements on the wall elements and the cooperating elements on the core element cooperate as the core element moves in the longitudinal direction in the cavity. The interacting elements move in the longitudinal direction with the elongate core, while the activating elements move in each of the radial directions together with their respective
DK 2020 00014 U1 wall element. The interaction between the cooperating elements and the activating elements transmits the longitudinal movement of the cooperating elements to a radial movement of the activating elements.
The actuating elements and the interacting elements thus cause the wall elements to move towards each other or away from each other in the respective first or second radial direction, thereby making the cavity smaller or larger as the core element moves in the longitudinal direction relative to the wall elements. Thus, the wall elements can be moved between the contracted state in which the wall elements have moved towards each other, reducing the radial distances, and consequently the circumference of the web according to the first and second aspects of the present invention and the cavity is small and an expanded state. , in which the wall elements have moved away from each other, increasing the radial distances and consequently the circumference of the tan in accordance with the first and second aspects of the present invention and the cavity is large. Typically, an upward movement of the elongate core member relative to the wall members provides an expansion of the circumference of the tan in accordance with the first and second aspects of the present invention, while a downward movement of the elongated core member relative to the wall elements provides a contraction of the circumference of the tan. in accordance with the first and second aspects of the present invention.
Typically, the wall elements of the tan according to the first and second aspects of the present invention are moved in directions spaced 90 ° apart, thus realizing a four-way expansion and contraction of the tan according to the first and second aspects of the present invention. Thus, the radial directions are perpendicular, i.e. located at a distance of 90 °. In this way, the general impression of the shape of the tan according to the first and second aspects of the present invention, i.e. the general circumferential profile, largely unaffected by the movements of the wall elements. In this way, the outwardly oriented pressure on the skin during the drying will be applied substantially uniformly in the skin by the outer surfaces of the arcuate elements. The outer surface of the wall elements will constitute the contact surfaces between the skin and the tan in accordance with the first and second aspects of the present invention, taking into account the possible presence of a skin bag between the skin and the tan according to the first and second aspects of the present invention. Using a two-way expansion and contraction, for example at opposite moving wall elements, will necessarily apply
DK 2020 00014 U1 more pressure on the skin at the moving surfaces relative to non-moving surfaces. Such non-uniformly applied pressure can lead to uneven skin or even damage to the skin.
When in the expanded state, the circumference of the tan according to the first and second aspects of the present invention is large. In this state, the skin is applied to the tan in accordance with the first and second aspects of the present invention, optionally using a skin bag. During the drying process, the skin loses fat and moisture and consequently contracts slightly. It may then be difficult to remove the skin from the tan. By contracting the tan according to the first and second aspects of the present invention by moving the wall elements towards each other, the circumference of the tan according to the first and second aspects of the present invention, as defined by the outer surfaces of the wall elements, will be smaller and thus typically allow that the skin is detached from the outer surfaces of the wall elements so that the skin can be removed from the tan in accordance with the first and second aspects of the present invention. In this context, the entire circumference of the tan according to the first and second aspects of the present invention will contract, effectively eliminating the risk of the skin adhering to the tan according to the first and second aspects of the present invention.
According to further embodiments of the tan according to the first and second aspects of the present invention, when in the contracted state, the first and second sets of oppositely placed longitudinal edges overlap, respectively, with the third and fourth set of oppositely placed longitudinal edges, or alternatively the third and fourth sets of oppositely positioned longitudinal edges overlap respective edges of the first and second sets of oppositely placed longitudinal edges, and, in the expanded state, the first and second sets of oppositely placed longitudinal edges are substantially in plane with respective edges of the third and fourth set of oppositely placed longitudinal edges.
In order to allow the skin to maintain an attractive surface structure, the outer surfaces of the wall elements should be at least substantially continuous. In order to obtain a substantially continuous outwardly oriented surface, the longitudinal edges of the wall elements in the expanded state should be substantially planar. This means that the outer surfaces of the wall elements form one in
DK 2020 00014 U1 is the essential continuous structure which avoids any large gap between the wall elements and adjacent exterior surfaces.
When the tan according to the first and second aspects of the present invention assumes the contracted state, and in order to maintain the general circumferential profile of the tan according to the first and second aspects of the present invention, it is advantageous that the longitudinal edges of adjacent wall elements in The web according to the first and second aspects of the present invention overlaps so that only a minor deviation from a continuous surface exists between adjacent exterior surfaces of the wall elements. It is understood from the foregoing that in order to realize the contraction, a portion of the wall elements located at the respective longitudinal edges of the wall elements may be pushed over or below its adjacent wall elements to form the overlap so that the longitudinal edges are not flat.
According to further embodiments of the tan according to the first and second aspects of the present invention, any of the first wall element, the second wall element, the third wall element and / or the fourth wall element define a central part and a peripheral part, the peripheral part comprising the set of edges. , the central part and the peripheral part are flexibly interconnected and when the first wall element, the second wall element, the third wall element and the fourth wall element define the contracted state, the peripheral part occupies an inwardly oriented position, while when the first wall element, the the second wall element, the third wall element and the fourth wall element define the expanded state, the peripheral portion occupies an outwardly oriented position.
In order to simplify the overlap of the wall elements and to minimize the space between adjacent wall elements, the wall elements may be partially flexible. Although it is fully possible to realize an expansion and contraction of the web according to the first and second aspects of the present invention via the wall element using rigid wall elements, the thickness of the wall element will typically prevent a fully planar outwardly oriented surface in the expanded state. By allowing the part of the wall element to be pushed under and / or over an adjacent wall element in the contracted state to be flexible with respect to the part of the wall element which must remain exposed to the skin, the longitudinal edges of the
DK 2020 00014 U1 adjacent wall elements are made to be fully level or continuous in the expanded state.
The central part of the respective wall element is movable in the respective first radial direction or the second radial direction in accordance with the movement of the corresponding wall element, while the peripheral part can be movable in both the first and second radial directions in order to be recorded above or below the adjacent wall element as described above.
According to further embodiments of the tan according to the first and second aspects of the present invention, the first actuating element and the second actuating element constitute pins and the first cooperating element and the second cooperating element constitute notes, for example linear or curved notes, in which the pins are passed between the the contracted state and the expanded state, or wherein the first cooperating member and the second cooperating member constitute pins and the first actuating member and the second actuating member constitute notes, for example, linear or curved notes in which the pins are passed between the contracted state and the expanded member. condition.
The above guiding principle, which uses a pin inserted in a groove, enables a well-defined movement of the wall elements. Obviously, the opposite configuration is equally usable, ie. with the first actuating member and the second actuating member as notes, for example linear or curvilinear notes, and the first cooperating member and the second cooperating member constituting pins guided by the notes between the contracted state and the expanded state, or any combination thereof. The longitudinal movement of the elongate core translates into a radial movement of the wall elements. The not / pin configuration also allows for very convenient locking of the wall elements and core.
According to further embodiments of the tan according to the first and second aspects of the present invention, the third activating element and the fourth activating element constitute wedge elements for contacting the third cooperating element and fourth cooperating element, or, the third cooperating element and the fourth cooperating element constitute wedge elements for to contact the third actuator and the fourth actuator.
DK 2020 00014 U1
Another guiding principle is used when using wedge elements which have an angle and consequently can slide outwards when pushed. Thus, the longitudinal motion of the elongate core member is converted to a radial motion by interaction between the sloping members. This guiding principle can preferably be applied when switching from the contracted state to the expanded state.
According to further embodiments of the tan according to the first and second aspects of the present invention, the third activating element and the fourth activating element further engage the interacting elements opposite the elongated core element.
Yet another guiding principle is used by employing activating elements which act on the side of the elongate core member which is located opposite the wall member to be moved. Thus, the longitudinal motion of the elongate core member is converted to a radial motion by interaction, typically using sloping members. This guiding principle can preferably be applied when switching from the expanded state to the contracted state.
According to further embodiments of the tan according to the first and second aspects of the present invention, each of the first wall element, second wall element, third wall element and fourth wall element has an arcuate shape such that each of the first outwardly oriented surface, the second outwardly oriented surface, the third outwardly oriented surface and the fourth outwardly oriented surface define a convex shape.
Applying a convex shape of the wall element will allow the outer surfaces of the wall elements to conform to the skin, which typically has a cylindrical shape.
According to further embodiments of the tan according to the first and second aspects of the present invention, each of the first wall element, second wall element, third wall element and fourth wall element comprises ventilation notes between the cavity and the outside of the tan according to the first and second aspect of the present invention.
Ventilation notes may be provided to allow dry air to be injected into the skin to remove any residual moisture in the skin, thereby reducing the drying time of the skin.
DK 2020 00014 U1
According to further embodiments of the tan according to the first and second aspects of the present invention, the first wall element, the second wall element, the third wall element and the fourth wall element define an opening between the cavity and the outside of the tan in accordance with the first and second aspects of the present invention. the bottom end to allow ventilation air to enter the cavity.
The dry air injected into the skin via the tan according to the first and second aspects of the present invention and used to reduce the drying time of the skin can be introduced into the tan according to the first and second aspects of the present invention via a cavity near the bottom end of the tan according to the present invention. with the first and second aspects of the present invention. The bottom end of the tan according to the first and second aspects of the present invention can typically be attached to a drying unit to hold the tan according to the first and second aspects of the present production in an upright position and to supply the drying air.
According to further embodiments of the tan according to the first and second aspects of the present invention, the third wall element and fourth wall element are firmly connected at the bottom end.
In order to increase the stiffness of the tan according to the first and second aspects of the present invention and to allow the tan according to the first and second aspects of the present invention to be readily connected to a drying unit, the tan according to the first and second aspects of the present invention have the same circumference at the bottom end both in the expanded state and in the contracted state. This can be achieved by firmly connecting the wall elements at a constant distance relative to each other near the bottom end and allowing the flexibility of the wall elements to determine the movement of the lower part of the tan according to the first and second aspects of the present invention. The lower outer end of the tan according to the first and second aspects of the present invention is typically not used to receive the skin, since the tan of this invention is typically formed longer than the longest skin for which the tan is intended.
According to further embodiments of the tan according to the first and second aspects of the present invention, the first wall element defines a first radial edge adjacent to the upper end of the elongate core, the second wall element comprises a second
DK 2020 00014 U1 radial edge adjacent to the upper edge of the elongate core, the tan according to the first and second aspects of the present invention further comprising:
a fifth wall element adjacent to the first wall element at the first radial edge, the fifth wall element extending along the longitudinal direction and away from the second wall element, the fifth wall element defining a fifth outwardly oriented surface and a fifth actuating element, a sixth wall element adjacent to the second wall element at the second radial edge, the sixth wall element extending along the longitudinal direction and away from the second wall element, which sixth wall element defines a sixth outwardly oriented surface and a sixth actuating element, the fifth and sixth wall elements being spaced apart in the first radial direction, and a core extension member connected to the upper end of the elongated core member and extending along the longitudinal direction away from the elongated core member, said core extension member being movable relative to the fifth wall member and sixth wall member, which ke The extension member comprises a fifth cooperating member cooperating with the fifth actuating member on the fifth wall member and a sixth cooperative member cooperating with the sixth actuating member on the sixth wall member to allow the fifth wall member and the sixth wall member to switch between the contracted state. and the expanded state by moving the elongate core member and the core extension member in the longitudinal direction relative to the first wall member, the second wall member, the third wall member, the fourth wall member, the fifth wall member, and the sixth wall member.
While sometimes possible, having a tan according to the first and second aspects of the present invention, which is expandable along its entire circumference, may be undesirable near the upper part of the tan according to the first and second aspects of the present invention. The upper part of the tan according to the first and second aspects of the present invention is intended to receive the neck and body part of the animal and since the neck and body part of the animal skin has a smaller circumference than the body part of the skin, the tan according to the first and second aspects is presently present. generally tapered towards the upper end with a thickness of the tan in accordance with the first and second aspects of the present invention which are reduced near the upper end of the tan according to the first and second aspects of the present invention, as described.
DK 2020 00014 U1 above. Since the actuating elements, interacting elements and elongate core elements require some space in the cavity, it may not be possible to allow the tan to expand and contract along its entire circumference, according to the first and second aspects of the present invention. a four-way expansion of the tan according to the first and second aspects of the present invention, as described above, at the upper end of the tan. Instead, at the top end of the tan, according to the first and second aspects of the present invention, the tan can be allowed to move only in two opposite directions.
The fifth wall element is an extension of the first wall element, the sixth wall element is an extension of the second wall element, while the core extension element is an extension of the elongated core element. The principle of motion in the first radial direction of the fifth wall element, the sixth wall element and the core extension element may be the same between the first wall element, the second wall element and the elongated core element, although the adjacent wall elements moving in the second radial direction are missing. Thus, this top structure comprising the fifth wall element and the sixth wall element can be made substantially thinner than the bottom structure comprising the first wall element, the second wall element, the third wall element and the fourth wall element. The fifth wall element and the sixth wall element may optionally be arcuate, but will typically be substantially planar due to the limited space available at the top of the tan in accordance with the first and second aspects of the present invention.
According to further embodiments of the tan according to the first and second aspects of the present invention, the third wall element and the fourth wall element comprise opposite extension elements which partially enclose the core extension element.
In order to increase the stiffness of the top structure relative to the bottom structure, the top structure may comprise opposing elongation elements which limit the radial movement or flexibility of the core elongation element. Thus, the core extension element is located between the opposing extension elements which are attached to the respective third wall element and fourth wall element.
According to further embodiments of the tan according to the first and second aspects of the present invention, the tan according to the first and second aspects of the present invention comprises:
A lower section comprising the first wall element, the second wall element, the third wall element, the fourth wall element and the elongated core element, an upper section comprising the fifth wall element, the sixth wall element and the core extension element, and an intermediate section located between the lower section and the upper section and comprising a core connecting member interconnecting the elongated core member and the core extension member, and a plurality of substantially elliptical cylindrical members surrounding the core connecting member.
The substantially elliptical cylindrical elements can be used to extend a short tane according to the first and second aspects of the present invention and make it suitable for larger animals. The substantially elliptical cylindrical members typically have no variable circumference, but the skin typically adheres to the tan according to the first and second aspects of the present invention near the top and bottom ends of the tan according to the first and second aspects of the present invention, so that they are elliptically cylindrical elements merely constitute spacers. This will have the advantage that the same tane according to the first and second aspects of the present invention can be used in connection with animals of very different sizes and the adjustment to the size of the specific animal will be made using the elliptical cylindrical elements. The core connecting member is simply used to connect the longitudinal movement from the elongated core member to the core extension member.
According to further embodiments of the tan according to the first and second aspects of the present invention, the fifth cooperating element and the sixth cooperating element constitute pins and the fifth activating element and the sixth activating element constitute notes, for example linear or curvilinear notes, in which the pins are passed between the contraction state, and the expanded state, or, the fifth actuating element and the sixth actuating element constitute pins and the fifth cooperating element and the sixth cooperating element constitute notes, for example, linear or curvilinear notes in which the pins are passed between the contracted state and the expanded state.
The above guiding principle, which uses a pin guided by a groove, enables a well-defined movement of the wall elements. This principle is explained above in connection with the first and second activation elements.
DK 2020 00014 U1
According to further embodiments of the tan according to the first and second aspects of the present invention, the fifth wall element is connected to the first wall element at the first radial edge and the sixth wall element is connected to the second wall element at the second radial edge.
By connecting the fifth wall element to the first wall element at the first radial edge and connecting the sixth wall element to the second wall element at the second radial edge, it can be ensured that the fifth wall element and the sixth wall element move uniformly and synchronously with the respective first wall element and other wall element. It is also possible to avoid squeezing the skin between the wall element and the arcuate wall elements at the first and second radial edges.
According to further embodiments of the tan according to the first and second aspects of the present invention, the elongated core member comprises a first projection adjacent the bottom end, the elongated core member being spring biased at the bottom end and defining a centralized relaxed position and a non-centralized loaded position in the first radial direction and / or the second radial direction, the first wall element, the second wall element, the third wall element or the fourth wall element comprise a second projection which cooperates with the first projection such that when the first wall element, the second wall element, the third wall element and fourth wall element define the expanded state and the elongated core element defines the centralized related position, the first and second projections prevent any longitudinal movement of the elongated core element, while the elongated core element defines the non-centralized bell position, the first and second projections allow longitudinal movement of the elongate core member.
The tan according to the first and second aspects of the present invention is maintained in the expanded state only because of the design and internal friction between the moving parts of the tan according to the first and second aspects of the present invention. The friction increases with the pressure applied to the tan according to the first and second aspects of the present invention, and although an increased friction may help to maintain the tan in accordance with the first and second aspects of this generation in the expanded state, even when a large When inward pressure is applied from the skin, it can also be very cumbersome to contract the tan according to the first and second aspects of the present invention. Experience has shown that after drying, when the skin is shrunk and thus exerts a great pressure on the tan according to the
DK 2020 00014 U1 first and second aspect of the present invention, the users must use a large manual force to cause the tan to contract according to the first and second aspects of the present invention. This work is very cumbersome and can lead to work-related injuries.
The locking mechanism described above, which uses cooperative projections to prevent movement of the elongate core member and thereby the contraction of the tan according to the first and second aspects of the present invention, allows the tan according to the first and second aspects of the present invention to remain in the expanded state. , even when subjected to very large inwardly oriented pressure, while reducing the amount of work required to shift the tan according to the first and second aspects of the present production to the contracted state. The first and second protrusions will interlock when the elongate core is in the central position, effectively preventing any longitudinal movement of the elongate core, which in turn prevents any radial movement of the wall elements.
By simply exposing the elongated core element to a small radial force exceeding the friction between the first and second projections and the spring constant of the elongated core element, the inwardly oriented pressure of the dried skin will cause the wall element to move inward and the second aspect of the present invention is contracted while the elongate core member is moved in the longitudinal direction and the first projection passes past the second projection.

The shift from the expanded state to the contracted state can preferably be made when the bottom end of the elongate core member is attached to the drying unit, for example by tilting the tan according to the first and second aspects of the present invention laterally, thereby also benefiting from the tipping arm provided by the tan according to the first and second aspects of the present invention to overcome the friction between the first and second projections.

The tane according to the third and fourth aspects of the present invention must have a total size suitable for receiving a fur from an animal such as a mink or fox. The web according to the third and fourth aspects of the present invention typically has a substantially elliptical cylindrical shape which is tapered in a longitudinal direction. The skin is applied to the tan in accordance with the third and fourth aspects of the present invention by pulling it on the tan according to the third and fourth aspects of the present longitudinal direction, while the tan according to the third and fourth aspects of the present invention assumes its expanded state. . It is to be understood that known leather bags may be used between the skin and the tan according to the third and fourth aspects of the present invention for the purpose of removing fatty substances from the skin. The wall elements typically comprise a large number of holes or nozzles to allow ventilation air to pass from the cavity of the tan in accordance with the third and fourth aspects of the present generation to the environment through the skin.
The first and second wall elements define the substantially elliptical outer circumference of the tan in accordance with the third and fourth aspects of the present invention, which are suitable for and adapted to receive an animal's skin via its respective outwardly oriented surfaces.

The wall elements are typically made of plastic. The wall elements are further defined in the circumferential direction by longitudinal edges.
DK 2020 00014 U1
The elongate core member located in the cavity is movable in the longitudinal direction relative to the wall members. The actuating elements on the wall elements and the cooperating elements on the core element cooperate as the core element moves in the longitudinal direction in the cavity. The interacting members move in the longitudinal direction along with the elongate core, while the actuating members move in any of the radial directions along with the respective wall member. The interaction between the interacting elements and the activating elements translates the longitudinal movement of the interacting elements into a radial movement of the activating elements.
The actuating elements and the interacting elements thus cause the wall elements to move towards each other or away from each other in the respective first or second radial direction, thereby making the cavity smaller or larger as the core element moves in the longitudinal direction relative to the wall elements. The wall elements are thus movable between the contracted state in which the wall elements have moved towards each other, reducing the radial distances, and consequently the circumference of the tan in accordance with the third and fourth aspects of the present invention, and the cavity is small and expanded. condition in which the wall elements have moved away from each other, increasing the radial distances and consequently the circumference of the tan in accordance with the third and fourth aspects of the present invention and the cavity is large. Typically, an upward movement of the elongate core member relative to the wall members provides an expansion of the circumference of the tan in accordance with the third and fourth aspects of the present invention, while a downward movement of the elongated core member relative to the wall elements provides a contraction of the perimeter of the tan. in accordance with the third and fourth aspects of the present invention.
The outer surface of the wall elements will constitute the contact surface between the skin and the tan in accordance with the third and fourth aspects of the present invention, except for the possible presence of a skin bag between the skin and the tan in accordance with the third and fourth aspects of the present invention.
When in the expanded state, the circumference of the tan in accordance with the third and fourth aspects of the present invention is large. In this state
DK 2020 00014 U1 is applied to the skin on the tan according to the third and fourth aspects of the present invention, possibly using a skin bag. During the drying process, the skin loses fat and moisture and consequently contracts slightly. It may then be difficult to remove the skin from the tan. By contracting the tan according to the third and fourth aspects of the present invention, by moving the wall elements towards each other, the circumference of the tan according to the third and fourth aspects of the present invention, as defined by the outer surface of the wall elements, will be smaller, thus allowing the skin to be detached from the outer surfaces of the wall elements so that the skin can be removed from the tan according to the third and fourth aspects of the present invention. In this context, the entire circumference of the tan according to the third and fourth aspects of the present invention will contract, effectively eliminating the risk of the skin adhering to the tan according to the third and fourth aspects of the present invention.
In order to simplify the overlap of the wall elements and to minimize the gap between adjacent wall elements, the wall elements can be partially flexible. Although it is fully possible to realize an expansion and contraction of the tan according to the third and fourth aspects of the present invention via the wall element using rigid wall elements, the thickness of the wall element will typically prevent a completely planar outwardly oriented surface in the expanded state. By allowing the part of the wall element to be pushed under and / or over an adjacent wall element in the contracted state to be flexible with respect to the part of the wall element which must remain exposed to the skin, the longitudinal edges of adjacent wall elements can be brought to be completely level or continuous in the expanded state.
According to a further embodiment of the tan according to the third and fourth aspects of the present invention, the first actuating element and the second actuating element constitute pins and the first cooperating element and the second cooperating element constitute notes, for example linear or curved notes, in which the pins are passed between the the contracted state and the expanded state, or wherein the first cooperating members and the second cooperating members constitute pins and the first actuating member and the second actuating member constitute notes, for example, linear or curved notes in which the pins are passed between the contracted state and the expanded member. condition.
DK 2020 00014 U1
The above guiding principle, which uses a pin inserted in a groove, enables a well-defined movement of the wall elements. It is clear that the opposite configuration is equally applicable, ie. having the first actuating element and a second actuating element for constituting notes, for example the linear or curvilinear notes, and the first cooperating element and the second cooperating element constituting pins guided by the notes between the contraction state and the expanded state, or any combinations thereof. The longitudinal movement of the elongate core is thus translated into a radial movement of the wall elements. The not / pin configuration also enables a very suitable interlocking of the wall elements and the core.
Another guiding principle is used by using wedge elements which have an angle and consequently can slide outwards by being pushed. Thus, the longitudinal motion of the elongate core member is converted to a radial motion by interaction between the sloping members. This guiding principle can preferably be applied when switching from the contracted state to the expanded state.
Yet another guiding principle is used by employing actuating elements which act on the side of the elongate member which is positioned opposite the wall member to be moved. Thus, the longitudinal motion of the elongate core member is converted to a radial motion by interaction typically using sloping members. This guiding principle can preferably be applied when switching from the expanded state to the contracted state.
According to a further embodiment of the present invention, the first wall element and the second wall element have an arcuate shape such that the first outwardly oriented surface and the second outwardly oriented surface define a convex shape.
Applying a convex shape to the wall element will allow the outer surfaces of the wall elements to conform to the skin, which typically has a cylindrical shape.
According to a further embodiment of the present invention, the first wall element and the second wall element comprise ventilation grooves between the cavity and the outside of the tan according to the third and fourth aspects of the present invention.
DK 2020 00014 U1
Ventilation grooves may be provided to allow dry air to be injected into the skin to remove any residual moisture in the skin, thereby reducing the drying time of the skin.
According to a further embodiment of the present invention, the first wall element and the second wall element define an opening between the cavity and the environment of the tan according to the third and fourth aspects of the present invention at the bottom end to allow ventilation air to enter the space.
The dry air which is injected into the skin via the tan according to the third and fourth aspects of the present invention and used to reduce the drying time of the skin can be introduced into the tan according to the third and fourth aspects of the present invention via a cavity near the bottom end of the tan according to the third and fourth aspects of the present invention. The bottom end of the tan according to the third and fourth aspects of the present invention can typically be connected to a dryer unit to hold the tan according to the third and fourth aspects of the present invention in an upright position and to supply the drying air.
According to the presently preferred embodiment of the elongated web according to the third and fourth aspects of the present invention according to the first and second aspects of the present invention, the first wall element and the third wall element are constituted by a first one-piece structure, the second wall element and the fourth wall element is constituted by another one-piece structure and the core element and the core elongation element are formed by another one-piece core element structure. Accordingly, this presently preferred embodiment of the tan according to the third and fourth aspects of the present invention according to the first and second aspects of the present invention is assembled by three separate elements, namely a single integrally formed core element structure and two identically formed integrally formed wall element structures. .
In order to increase the stiffness of the tan according to the third and fourth aspects of the present invention and to enable the tan according to the third and fourth aspects of the present invention to be readily connected to a drying unit, the tan according to the third and fourth aspects of the present invention can have the same circumference at the bottom end both in the expanded state and in the contracted state. This can be achieved by firmly connecting the wall elements at a constant distance to each other
DK 2020 00014 U1 near the bottom end and allow the flexibility of the wall elements to determine the movement of the lower part of the tan according to the third and fourth aspects of the present invention. The lower end of the tan according to the third and fourth aspects of the present invention is typically not used to receive the skin, since the tan according to the third and fourth aspects of the present invention is typically made longer than the longest skin, for which the tan according to the third and fourth aspect of the present invention is intended.
According to a further embodiment of the tan according to the third and fourth aspects of the present invention, the first wall element defines a first radial edge adjacent to the upper end of the elongated core, the second wall element comprises a second radial edge adjacent to the top edge of the elongated core. , the tan further comprises:
a third wall element adjacent to the first wall element at the first radial edge, said third wall element extending in the longitudinal direction and away from the second wall element, the third wall element defining a third outwardly oriented surface and a third actuating element, a fourth wall element in contact to the second wall element at the second radial edge, the fourth wall element extending in the longitudinal direction and away from the second wall element, the fourth wall element defining a fourth outwardly oriented surface and a fourth activating element, said third and fourth wall elements being mutually distance in the first radial direction, and a core extension member connected to the upper end of the elongated core member and extending along the longitudinal direction away from the elongated core member, which core extension member is movable relative to the third wall member and fourth wall member, the actuating member comprises a third cooperating member cooperating with the third actuating member of the third wall member and a fourth cooperating member cooperating with the fourth actuating member of the fourth wall member to allow the third wall member and the fourth wall member to alternate between the contracted state and the expanded state by moving the elongate core member and the core extension member in the longitudinal direction relative to the first wall member, the second wall member, the third wall member, and the fourth wall member.
While sometimes desirable, having a tan expandable along its entire circumference may be undesirable near the upper part of the tan according to the third and fourth
DK 2020 00014 U1 aspect for the present invention. The upper part of the tan is intended to receive the neck and body part of the animal and since the neck and body part of the animal skin has a smaller circumference than the body part of the skin, the tan is usually tapered towards the apex with a thickness of the tan which is reduced near the top. of the tan, as described above. Since activating elements, interacting elements and elongated core element require some space in the cavity, it may not be possible to allow the tan to expand and contract along its entire circumference at the upper end of the tan.
According to a further embodiment of the tan according to the third and fourth aspects of the present invention, the third wall element and the fourth wall element comprise opposite extension elements which partially enclose the core extension element.
According to a further embodiment of the tan according to the third and fourth aspects of the present invention, the tan comprises:
a lower section comprising the first wall element and the second wall element and the elongate core element, an upper section comprising the third wall element, the fourth wall element and the core extension element, and an intermediate section located between the lower section and the upper section and comprising a core connecting element which interconnects the elongate core member and the core extension member.
According to a further embodiment of the tan according to the third and fourth aspects of the present invention, the third cooperating element and the fourth cooperating element constitute pins and the third activating element and the fourth activating element constitute notes, for example linear or curved notes, in which the pins are passed between the the contracted state and the expanded state; or, the third actuating member and the fourth actuating member constitute pins, and the third cooperating member and the fourth cooperating member constitute notes, e.g., linear or curved notes, in which the pins are passed between the contracted state and the expanded state. .
DK 2020 00014 U1
The abovementioned guiding principle, using a pin guided by a groove, enables a well-defined movement of the wall elements. This principle is explained above in connection with the first and second activation elements.
According to a further embodiment of the tan according to the third and fourth aspects of the present invention, the third wall element is connected to the first wall element at the first radial edge and the fourth wall element is connected to the second wall element at the second radial edge.
By connecting the third wall element to the first wall element at the first radial edge and connecting the fourth wall element to the second wall element at the second radial edge, it can be ensured that the third wall element and the fourth wall element move uniformly and synchronously with the respective first wall element. and other wall element. It is also possible to avoid squeezing the skin between the wall element and the arcuate wall elements at the first and second radial edges.
According to a further embodiment of the tan according to the third and fourth aspects of the present invention, the elongated core element comprises a first projection adjacent the bottom end, the elongated core element being spring loaded at the bottom end and defining a centralized relaxed position and a non-centralized loaded position in the first radial direction and / or second radial direction, the first wall element and the second wall element comprise a second projection which cooperates with the first projection such that when the first wall element and the second wall element define the expanded state and the elongated core element defines the centralized related position, the first and second projections prevent any longitudinal movement of the elongated core member, while, when the elongated core member defines the non-centralized loaded position, the first and second projections allow longitudinal movement of the elongated core member ement.
The tan according to the third and fourth aspects of the present invention is retained in the expanded state only because of the design and internal friction between the moving parts of the tan. Friction increases with the pressure applied to the tan and although increased friction can help keep the tan in the expanded state, even when a large inward pressure is applied from the fur, it can also be very cumbersome to contract the tan. Experience has shown that after drying, when the skin has shrunk and thus exerts a great pressure on the tan, users must use great manual force to
DK 2020 00014 U1 bring the tan to contract. This work is very cumbersome and can lead to work-related injuries.
The aforementioned locking mechanism, which uses cooperative projections to prevent movement of the elongate core member and thereby contraction of the tan, allows the tan to remain in the expanded state, even when subjected to very large inwardly oriented pressure while reducing the amount of work. , which is required to switch the tan to the contracted state. The first and second projections will interlock when the elongate core member is in its central position, effectively preventing any longitudinal movement of the elongate core, which in turn prevents radial movement of the wall members.
By simply exposing the elongated core member to a small radial force which exceeds the friction between the first and second projections and the spring constant of the elongated core member, the inwardly oriented pressure from the dried skin caused by the wall member moves inward and the taper is contracted. elongate core member moves in the longitudinal direction and the first projection passes past the second projection. This mechanism will also be less susceptible to accidental activation since it does not depend on any hard-to-determine internal friction between the actuating elements and the interacting elements.
It is clear that the aforementioned locking mechanism can be applied to a general tane which does not necessarily include the four-way expansion. Such a tane may, for example, be defined as an elongated tane for receiving an animal skin which defines a longitudinal direction, a first radial direction perpendicular to the longitudinal direction, and a second radial direction perpendicular to the longitudinal direction and the first radial direction, the tan has a wall member and an elongated core member covered by the wall member, which wall member is capable of assuming an expanded state and a contracted state upon longitudinal movement of the elongated core member, said elongated core member comprising a first protrusion adjacent to a bottom of the tan, the core element is spring loaded at the bottom end and defines a centralized relaxed position and a non-centralized loaded position in the first radial direction and / or second radial direction, the wall element comprising a second projection which cooperates with the first projection such that when the wall element defines the expanded t disorder and the elongated core element define the centralized related position, the first and second projections prevent any longitudinal movement of
DK 2020 00014 U1 the elongated core member, while when the elongated core member defines the non-centralized loaded position, the first and second projections allow longitudinal movement of the elongated core member.
The change from expanded state to compressed state can preferably be made while the bottom end of the elongated core member is connected to the drying unit, for example by tilting the tan laterally, taking advantage of the barbell principle provided by the tan to overcome friction between the first and second projections.

The upper surface defines a receiving aperture having a configuration which corresponds to the connecting element of the tan and serves to receive the connecting element for supporting the tan in an upright position with respect to the upper surface, an air inlet is provided into the inner cavity at the bottom end of the tan to allow air to be introduced into the interior cavity and to be forced out through the apertured wall for drying the inwardly oriented leather side of the skin, the air inlet defining an inlet area constituting at least 15% of the the bottom area of the tan and less than about 95% of the bottom area, and preferably more than 30% of the bottom area, such as further preferably about 45-50% of the bottom area of the tan, and an air outlet provided at the upper surface of the housing to communicate with the air inlet and defining an outlet area constituting between 15% and 95% of the bottom area, such as preferably show more than 30%, such as preferably 45-50% of the bottom area of the tan.
According to the studies and experiments carried out by the applicant, which will be discussed below, it has been found that tans developed by the applicant's company and also by the competitor company Jasopels A / S and known as FIX tane 2 and XLtane respectively. , has a constraint with respect to the volume of air which can be forced through the tans, which is primarily determined by the air inlet into the tane concerned, which air inlet is established through the connecting part of the tane, which connecting part of the prior art is described as a loss-shaped element. Apart from the inlet constraint, the general configuration and in particular the hollow surface of the tan also establishes a restriction on the air inlet capacity or the volumetric air inlet capacity for the previously known tans. In accordance with the teachings of the present invention, as stated in the ninth aspect of the present world, the air outlet from the drying unit and the air inlet into the tan, which drier and tan constitute a system in accordance with the ninth aspect of the present invention, has a large transition area which permits a substantial increase of air inlet into the tan, which in turn improves the drying capacity or reduces the drying time for drying the skins mounted on the tans.

FIG. 1A shows a perspective view of a first embodiment of a tane 10 in the contracted state. The web 10 comprises a lower portion 12 and an upper portion 14. The lower portion 12 comprises a first arcuate wall member 16, a second wall member 18, a third wall member 20, and a fourth wall member 22, which together define a cavity 24, wherein an elongated core member 26 are located. The first arcuate wall member 15, the second wall member 18, the third wall member 20 and the fourth wall member 22 are shown schematically here as solid, however, it should be understood that for optimum drying of the skin,
They should be laminated to allow ventilation air to pass from the tan to the skin. The upper portion 14 comprises a fifth wall member 28 and a sixth wall member 30, both of which are in the present case arcuate and tapered, but which may also be manufactured non-arcuate and non-tapered. The elongate core member 26 extends into the upper portion 14 in the form of a core extension member 26 '.
The first wall element 16 and the second wall element 18 comprise respective peripheral elements 16 ', 16, 18', 18 which are flexibly connected to the central elements of the respective first wall element 16 and the second wall element 18. The third wall element 20 will in the present contraction condition, the peripheral elements 16 ', 18' and the fourth wall element 20 overlap in the present contraction state overlap the peripheral elements 16, 18. The fifth wall element 28 and a sixth wall element 30 both overlap. An extension member 32 interconnects the lower part 12 and the upper part 14.
FIG. 1B shows a perspective view of the first embodiment of the tan 10 in the expanded state. By pushing the elongated core member 26 in a longitudinal direction, as shown by arrows, all the wall elements are forced in outwardly oriented directions as shown by arrows. The first wall element 16 and the fifth wall element 28 are moved along a first radial dimension, while the second wall element 18 and the sixth wall element 30 are moved along the first radial dimension, but in the opposite direction, the first radial dimension is perpendicular to the longitudinal direction defined. of the elongated core member 26. The third wall member 20 and the fourth wall member 22 are forced in opposite directions along a second radial direction as shown by the arrows, which second radial direction is perpendicular to both the first radial dimension and the longitudinal dimension. The peripheral portions 16 ', 16, 18', 18 of the respective first wall member 16 and second wall member 18 move along both the first and second radial dimensions so that the expanded web 10 'forms a smooth outer surface.
FIG. 2A shows a cut-away perspective view of another embodiment of a tane 10 'in the contracted state. The third wall element 20 and the fourth wall element 22 comprise activating elements 34 along the longitudinal dimension and the elongate core element 26 comprises cooperating elements 36 along the longitudinal dimension. The actuating elements 34 and the cooperating elements 36 define opposing wedges. In the contracted state of the tan 10, the sloping surface is on
The opposite wedges do not overlap or overlap so that no outwardly oriented force is generated, ie. that the protruding parts of the opposing wedges are not overlapping.
The fifth wall element 28 and the sixth wall element 30 comprise activating elements 34 'along the longitudinal dimension and the elongate core element 26 comprises cooperating elements 36' along the longitudinal dimension. The actuating elements 34 'define curvilinear grooves along the longitudinal dimension of the fifth wall element 28 and the sixth wall element 30, while the interacting elements 36 define pins on the core extension element 26'.
FIG. 2B shows a cut perspective view of the tan 10 'in the expanded state. The inclined surfaces and the opposite wedges are now overlapping so that an outwardly oriented force is obtained, ie. the projecting portions of the opposed wedges are overlapping causing the third wall element 20 and the fourth wall element 22 to move outward in opposite directions.
As the core extension member 26 'moves along the elongated core member 26 along the longitudinal dimension, the pins forming the interacting members 36' move along the curved grooves constituting the actuating members 34 ', thereby causing the fifth wall member 28 and the sixth wall element moves outward in opposite directions.
The movement of the first wall element 16 and the second wall element 18 will be explained in detail in the following figures.
FIG. 3 shows a perspective view of a further embodiment of a tane 10. In the present embodiment, the fifth wall element 28 and the sixth wall element 30 are substantially planar in order to be able to receive the neck portion of the animal skin. The surface of the arcuate wall elements 16, 18, 20, 22 has ribs 38 to allow the fur to be properly fixed to the tine 10. Further, all of the wall elements 16, 18, 20, 22 have ventilation holes 40.
FIG. 4 shows a perspective view of the upper part 14 of the tane 10. It shows in detail how the fifth wall element 28 and the sixth wall element 30 are both connected.
DK 2020 00014 U1 with the core extension element 26 '. The actuating elements 34 ', in the form of curved notes, are connected to the cooperating elements 36' in the form of pins. Upon longitudinal movement of the core extension member 26 ', the pins will follow the path defined by the curved notes and thus cause the fifth wall element 28 and the sixth wall element 30 to move outward along the curve defined by the interaction between the curved notes and pins.
FIG. 5 shows a perspective view of the lower part 12 of the tine 10. In the present embodiment, the first wall element 16 is composed of two elements denoted by reference numerals 16A and 16B, which are interconnected via a clip connection 42. The second wall element 18 is also composed of two elements denoted by reference numerals 18A and 18B and which are interconnected by a clip connection 42.
FIG. 6A shows a perspective view of the lower part 12 of the tane 10. The present image shows in particular a close-up view of the elements 16A, 16B, 18A, 18B which constitute the first wall element 16 and the second wall element 18. In order to bring the first wall member 16 and the second wall member 18 to move in the first radial direction define the clip mechanisms 42, 42 'when assembled, activating members 34 in the form of pins. The elongate core member 26 defines cooperating members 36 in the form of curved notes. The working principle of the curved notes and the pins is the same as for the upper part of the taper 10. The pins are guided by the curved notes and forced inward / outward in accordance with the longitudinal movement of the elongate core member 26. Thereby the first wall element 16 and the second wall element 18 is along the first radial dimension and at the same time the first wall element 16 and the second wall element 18 are retained by the elongated core element 26.
The wall elements 16A, 16B, 18A, 18B also comprise a plurality of respective peripheral portions 44 which are flexibly connected to their corresponding wall elements 16A, 16B, 18A, 18B.
FIG. 6B shows a perspective view of the lower portion 12 of the tine 10 when assembled. When interconnected, each of the clip mechanisms 42, 42 'will form a pin 34 to be inserted into the curved groove of the elongate core member 26. The peripheral members
DK 2020 00014 U1
44, which will be described in detail below, form a substantially smooth and continuous surface together with their corresponding wall element 16, 18.
FIG. 7A shows a close-up view describing the operating principle of the elongate core member 26, the wall member 16A and the corresponding peripheral portion 44. The present image represents the contraction state of the tan. The elongate core member 26 comprises a further cooperating member 36 'which constitutes a wedge and which is adapted to cooperate with an activating member 34' which forms a projection on the peripheral portion 44.
FIG. 7B shows the arrangement of FIG. 7A when in the expanded state. The elongate core member 26 moves in the longitudinal direction relative to the wall member 16A and causes the wall member 16A to move outwardly in the first radial direction as indicated by the arrows. The outward movement of the wall element 16A is caused by the interaction between the interacting element 36 'and the activating element 34'. The longitudinal movement of the elongate core member 26 causes the actuating member 34 'forming a protrusion to slide on the cooperating member 36' constituting a wedge, thereby causing the peripheral portion 44 to move outwardly in both the first and the other radial direction as shown by the arrow.
FIG. Fig. 8A shows a perspective view illustrating how the third wall element 20 and the fourth wall element 22 are attached to each other and to the elongate core element 26. The third and fourth wall elements 20, 22 each comprise additional activating elements in the form of fasteners 46 which cooperate with corresponding groove 48 in the elongate core member 26. In the present embodiment, the third and fourth wall members 20, 22 are further interconnected via corresponding clip mechanisms 50, 50 'at the bottom end of the web.
FIG. 8B shows the lower part 12 of the tan when the third wall element 20 and the fourth wall element 22 are attached to each other and to the elongated core element 26.
FIG. 9A shows a close-up view illustrating the operating principle of the third wall element 20 and the fourth wall element 22. The third wall element 20 and the fourth wall element 22 each comprise activating elements 34 and the elongated core element 26 comprises cooperating elements 36. The activating elements 34 and the cooperating elements
DK 2020 00014 U1 defines wedges which slope in the opposite direction. In the present contracted state, the wedges in the actuating member 34 and the cooperating members 36 are positioned so that the protruding parts of the wedges are non-overlapping, allowing the third wall member 20 and fourth wall member 22 to define a small distance therebetween. In this case, the fastening element 46, as described in detail in the preceding figure, will cooperate with the corresponding grooves 48 in the elongate core element 26 such that each of the third wall element 20 and the fourth wall element 22 is pulled inwardly against the elongated core element 26.
FIG. 9B shows a close-up view illustrating the working principle of the third wall element 20 and the fourth wall element 22 when in the expanded state. In the present expanded state, the wedges in the actuating elements 34 and the cooperating members 36 are positioned so that the protruding parts of the wedges are overlapping, causing the third wall element 20 and the fourth wall element 22 to define a greater distance between them. The movement principle of the third wall element 20, the fourth wall element 22 and the elongated core element 26 is illustrated by the arrows.
FIG. 9C shows a close-up view illustrating the working principle of the fastener element 46 when the tan is in the expanded state. The fastening element 46 has a wedge shape for controlling the distance between the elongate core element 26 and each of the third wall element 20 and the fourth wall element 22, depending on the longitudinal position of the elongate core element 26. The fastening element 46 for the respective third wall element 20 and fourth wall element 22 engages the groove 48 in the elongate core member 26 which is opposite the third wall member 20 of which the present fastener 46 is a part.
FIG. 9D shows a close-up view illustrating the working principle of the fastener element 46 when the tan is in the expanded state. The contraction of the third wall element 20 and the fourth wall element 22 can be controlled by the inclination of the fastening element causing the third wall element 20 and the fourth wall element 22 to move closer to the elongated core element 26 as the tan enters the contracted state.
FIG. 10A shows the mounting principle for the upper part 14. In the first step, the fifth wall element 28 and the sixth wall element 30 are placed in a partially overlapping
DK 2020 00014 U1 position around the core extension element 26 '. In the next step, the interacting members 36 'constituting pins are placed through the actuating elements 34', which are curved notes, and through the center of the core extension element 26 '.
FIG. 10B shows a perspective view of the upper part 14 when mounted and in the expanded state.
FIG. 11A shows the principle of motion of the upper part 14 of the tan. The cooperating members 36 'are inserted into the actuating members 34' to cause the fifth wall member 28 and the sixth wall member 30 to minimize the radial dimension therebetween and relative to the core extension member 26.
FIG. 11B shows the principle of motion of the upper part 14 of the tan. The cooperating members 36 'are inserted into the actuating members 34' to cause the fifth wall member 28 and the sixth wall member 30 to increase the radial dimension therebetween and relative to the core extension member 26 as the core extension member 26 moves in the longitudinal direction as indicated by the arrows.
FIG. 12A shows a perspective view of a further embodiment of a tane 10 '. The tab 10 'is similar to the tabs of the preceding embodiments, but in order to be able to adjust the length of the tab 10', intermediate sections 52 are included between the upper portion 14 and the lower portion 12. The intermediate sections 52 constitute elliptical cylindrical spacers which are non-expandable. The intermediate sections 52 may be made non-expandable, since the skins are most likely to adhere to the upper part 14 and the lower part 12. However, the intermediate sections 52 may also be made expandable correspondingly to the lower part 12 or the upper part 14. For large skins, several intermediate sections 52 are used. A core connecting member 26 can be used to interconnect the elongated core member in the lower portion 12 and the core extension member of the upper portion 14.
FIG. 12B shows a perspective view of a third embodiment of a tane 10 'and illustrates how the lower portion 12 and upper portion 14 expand as shown by the arrows while the intermediate sections remain constant in circumference.
FIG. 13 is a perspective view of a fourth embodiment of a tane 10 ^IV . The present web 56 comprises a plurality of ribs 56 which help to retain the skin
DK 2020 00014 U1 tanen. Further, there are a number of ventilation holes 40 to allow the skin to dry quickly. The tab 10 ^IV has an elliptical configuration and the third and fourth wall elements 20, 22, with an arcuate configuration, can overlap the first and second wall elements 16, 18 to assume the expanded state and the contracted state. The elongated core element is omitted in the present image. A large opening 58 is provided at the bottom end of the tan 10 ^IV to allow a large amount of dry ventilation air to enter the tan 10 ^IV .
FIG. 14 shows the bottom end of the lower part 12 of the tan. The lower end of the third wall element 20 and the fourth wall element 22 are secured by cooperating clip mechanisms 50, 50 'such that the third wall element 20 and the fourth wall element 22 cannot move relative to each other in contact with the lower end. of the tan. Typically, the skin does not stop a few centimeters above the lower end, otherwise a longer tan should be used. Thus, it is not necessary for the third wall element 20 and the fourth wall element 22 to be movable adjacent the lower end of the tan. A connecting member 60 is used to move the elongated core member 26 in the longitudinal direction. Further shown, first locking projections 62 are located on each of the third wall member 20 and the fourth wall member 22. Second locking projections 64 are located on the connecting member 60. The locking projections 62, 64 are used to lock the elongated core member 26 in the expanded state. This is explained further in the following.
FIG. 15 shows the lower portion 12 of the tan when assembled. The connecting member 60 extends from an opening 58 'at the lower end of the tine. The orifice 58 'is preferably large to allow a large flow of air to enter the interior of the tan 10 and most preferably the orifice 58' defines most of the entire bottom surface of the tan
10. The aperture 58 'typically constitutes the limiting flow surface which determines the amount of air which will flow through the tan. A small opening 58 'would restrict flow, causing less efficient drying of the skin.
FIG. 16 shows a perspective close-up view of the connecting element 60 and the locking principle used to lock the tan in the expanded state. The third and fourth wall elements comprise first locking projections 62, while the connecting element 60 comprises second locking projections 64. The connecting element 60 is flexible in the first radial direction with respect to the third and fourth wall elements. The present locking mechanism is located adjacent to the bottom end of the tan and together with the friction between the
DK 2020 00014 U1 internal moving parts in the tan, ie. the activating elements and the interacting elements, it will eliminate the need for any additional locking mechanisms inside the tan. The present locking mechanism should be located adjacent to the bottom end of the tan to prevent it from being clamped by grease substances which may come from the skin. The shift from expanded state to contracted state can preferably be made when the bottom end of the elongated core member is attached to the drying unit, for example by tilting the tan laterally, thereby also taking advantage of the barbell principle provided by the tan to overcome friction between the first and second projections.
FIG. 17A shows the locked position of the tan. The first locking projections 62 are located below the second locking projections 64. Thus, the first locking projections 62 prevent the longitudinal movement of the connecting member 60 and thus of the elongated core member.
FIG. 17B shows the unlocking of the tan. By moving the connecting member 60 in the first radial direction, the second locking projection 64 is freely movable past the first locking projection 62.
FIG. 17C shows the movement from the expanded state to the contracted state of the unlocked tane. By moving the connecting member 60 in the longitudinal direction so that the second locking projection 64 moves past the first locking projection 62, the state can be changed from the expanded state to the contracted state.
FIG. 17D shows the connecting member 60 when the tan is in the contracted state. Upon release of the connecting member 60, this springs back to its central relaxed position.
FIG. 18A is a perspective view of a further embodiment of a tan 10 ^V when in the contracted state. The tan 10 ^V comprises movable wall elements 16, 16 ', 16, 18, 18', 18, 20, 22, which together do not cover the entire circumference of the tan. Between the wall elements 16, 16 ', 16, 18, 18', 18, 20, 22, fixed wall elements 54 are placed. When in the contracted state, the wall elements 16, 16 ', 16, 18, 18', 18, 20, 22 form a smooth outer surface together with the solid wall elements 54.
DK 2020 00014 U1
FIG. Fig. 18B shows a perspective view of a further embodiment of a tan 10 ^V when in the expanded state. When in the expanded state, the wall elements 16, 16 ', 16, 18, 18', 18, 20, 22 move outwardly and form contact surfaces for the skins. The principle of motion for the wall elements 16, 16 ', 16, 18, 18', 18, 20, 22 is not shown, but preferably the same principles are used as for the previous embodiments.
FIG. 19 shows the tan during drying when connected to a drying unit 66. The drying unit 66 has a fan 68 and a plurality of ventilation openings 70. The fan provides a flow of air which is passed through the ventilation openings 70 into the tane 10 through the openings 58 'at the lower part 12 of the tan 10.
FIG. 20A shows a perspective view of a further embodiment of the tan 10 ^VI in which the first wall element 16 is integrally connected to the third wall element 20 as indicated by a connecting line 17, and correspondingly the second wall element 18 is integrally connected to the fourth wall element 22 via a connection line 19. The embodiment of the tan 10 ^VI shown in FIG. 20A-20C represent the additional feature of allowing the tan to be expanded in two alternative and separate directions; a first direction shown in FIG. 20B as indicated by the arrows, according to which expansion, the third wall element and the fourth wall element 22 are spaced apart for expansion of the tan in a first transverse direction and correspondingly in FIG. 20C, the expansion of the tan 10 ^{VI is} caused by displacing the first wall element 16 and the second wall element 18 relative to each other to expand the tan in a direction indicated by the arrows in FIG. 20C which is perpendicular to the direction of expansion shown in FIG. 20B.
FIG. 21A and 21B illustrate in more detail the expansion of the tan 10 ^VI in the first transverse direction indicated in FIG. 20B and the like, in FIG. 22A and 22B, the expansion in the second transverse direction is illustrated in more detail.
As indicated in FIG. 20B and FIG. 20C and the like in FIG. 21A and 22A, the expansion in the second transverse direction is obtained as a further movement of the elongate core member 26, the movement of the central core member 26 from the position shown in FIG. 20A to the position shown in FIG. 20B provides the expansion of the tan in the first transverse direction and further movement of the central core member 26, as indicated in FIG. 20C, provides the further expansion within it
DK 2020 00014 U1 other transverse direction. By modifying the actuating elements 34, 36 and 46, 48 or repositioning them relative to each other, the shift from the non-expanded state to the fully expanded state can be shown in FIG. 20C is obtained in a different way by first displacing the first and second wall elements 16, 18 relative to one another and then displacing the third and fourth wall elements 18, 20 relative to each other. In yet another variant of the tan 10 ^VI , the displacement of the tan from the non-expanded state to the first or second expanded state shown in FIG. 20B and 20C, respectively, are obtained selectively by displacing the central core member 26 laterally to contact the one set of activating members 34, 36 shown in FIG. 21B or alternatively the second set 46, 48 shown in FIG. 22B.
FIG. 24-27 illustrate a three-component embodiment of the tan 10 ^{* * IV} , which embodies the presently preferred embodiment of the tan according to the present invention.
In FIG. 24, two shell parts 28 and 30 are shown, showing the outer surfaces of the two shell parts and further, in the left part of FIG. 24 showing the upper ends of the two shell portions, which upper ends serve to grip and fix a portion of the skin at the head of the skin. As can be seen from the enlarged image of FIG. 24, on the left side of FIG. 24, the upper ends are provided with gripping claws or teeth which serve to fix the head of the skin relative to the tan.
In FIG. 25, the two shell portions 28 and 30 are shown in separate condition releasing the central elongate core member 29 which at its lower end and outwardly projecting portion serves to cooperate with a conventional tanning machine and a conventional drying machine.
In FIG. 26 and 27 are further details, illustrated in enlarged images A-G, for the tans shown. In A and B, the outer surface of the upper part of the tan is shown, illustrating the longitudinal ridges of the tan and edge openings. In C, the upper end of the shell portion 28 illustrating the gripper teeth is also shown in FIG. 24. In D, the cam faces of the elongate member 29 are shown in more detail and in E the internal locking members of the shell portion 30 are shown. In F, the lower outwardly extending or protruding elements constituting a so-called pin-shaped element are shown, and in G the locks of the shell part 30 are shown in more detail.
DK 2020 00014 U1
In general, the above described preferred embodiment 10 ^VI of the tan according to the present invention satisfies the following features which are characteristic of the embodiment. The shell portions 28 and 30 are forced relative to the longitudinal core member 29 at a total of six positions along the shell portions, the forcing or guide being established during expansion as well as during contraction of the tan. The locks of the tan serve as a friction lock which prevents contraction and expansion of the tan until an external force generated by a skin applied to the tan activates the latch. The expansion in both transverse directions and also the contraction in both transverse directions is forcibly controlled and guided. The aforementioned tap-shaped elements, together with the lower end of the shells, serve to center the tan in a drying box or dryer and provide a stop in the drying box. In addition, the tapered member, as distinct from previously used tapered members, serves to grip and lock in the tan machine and in the dryer or dryer providing gripper flanges or elements for improved fixation. To provide individual detection of the skin received on a specific tane, the tane is further provided with an internal holder for receiving an RFID (Radio Frequency Identification Device).
The shell parts exhibit the following additional features of providing holes for drying the back of the skin and providing an increased air flow compared to conventional and commercially available tans. In the longitudinal direction of the tan, the shell portions are reinforced for every 60 mm and transverse bands are further provided for every 30 mm. The total surfaces of the two shell parts prevent vertical displacement of the skin relative to the tan and the teeth at the upper end of the two shell parts fix the upper end, ie. the head of the skin relative to the tan. The number of teeth for gripping the head of the skin may be any number such as, 2, 4, 6, 8 or even more teeth, the presently preferred embodiment having a total of 4 teeth on each of the two shell parts 28 and 30. The total lane 10 ^VI shown in FIG. 24-27 further provide the advantage of contracting the tan throughout its length and allowing machine-driven removal of the skin from the tan. The total cross-section of the tan corresponds to the geometry of an ellipse of the non-expanded or contracted state, which provides an improved function for easy mounting of the skin and easy removal of the skin after contraction of the tan. The high number of air openings which serve to allow air to circulate through the tan and further through the skin allows the drying air to pass from the inside of the tan to the outside. The total opening air layer of the total transverse opening area of the tan is approximately 1200 mm ² , calculated as the open area. Upon drying of the skin, as shown in FIG. 25 and 26, inserted inside
DK 2020 00014 U1 the tan along approximately 60% of the total length of the tan and then transferred to the outer surface of the tan via the openings shown in the enlarged images A and B of FIG. 26th
FIG. 28A shows a perspective view of a portion of a further embodiment of a tan 10 ^{I * * * V} in its contracted or non-expanded state. The tab 10 ^{VH is} similar to the embodiment 10 ^VI described above in FIG. 20A, 20B, 20C, 21A, 21B, 22A, 22B, 23A, 23B and 23C. The portion of tan 10 ^V shown in FIG. 28A constitutes the lower portion 12 'of the tan shown in FIG. 31A and 31B, which will be described in more detail below.
The lower portion 12 'of the tan 10 ^VH is composed of a total of three components, namely two identically shaped shell portions 72 and 74 and a central elongated core member 26.
Each of the shell portions 72 and 74 comprises a larger low curvature wall portion 22 'and 20', respectively, a smaller high curvature wall portion 18 'and 16', respectively. the larger low curvature wall portions 22 'and 20' are connected to the smaller high curvature portions 18 'and 16', respectively, via imaginary lines 17 'and 19', respectively.
The embodiment of the tan 10 ^V shown in FIG. 28A has a structure in which the two identically shaped shell portions 72 and 74 in the contracted or non-expanded state, shown in FIG. 28A, constitutes an almost perfectly configured elliptical cross-sectional configuration, the longitudinal edges of the opposed located shell portions 72 and 74 being interconnected in a basically unbroken elliptical cross-sectional configuration. The elliptical cross-sectional configuration of the tan 10 ^VH shown in FIG. 28A is considered to improve the ability of the tan to allow easy removal of the skin from the tan after tanning the skin, with the outer surface of the tan 10 ^V in its collapsed or collapsed state being almost perfectly uniform with no significant discontinuities.
In FIG. 28B, the embodiment of the tan 10 ^{V is} shown in its expanded state, in which the two shell portions 72 and 74 are caused to be displaced from one another while establishing a gap between the edges of the opposed shell portions 72 and 74.
The displacement of the shell portions 72 and 74 apart, as illustrated in FIG. 28B and indicated by arrows is obtained by displacing the central elongate core member 26 in a direction also indicated by an arrow inwardly of the inner 10 ^V , forcing the shell portions 72 and 74 apart.
DK 2020 00014 U1
The separation or displacement of the shell portions 72 and 74 is achieved by cooperating actuating elements 34 and 36 shown in FIG. 28C which are identical to the activating elements 34 and 36 shown in FIG. 21B and described above, the actuating elements 34 being triangular shaped bodies extending inwardly from the central portion of larger low curvature wall portion 22 'of the shell portion 72 and also from the larger low curvature wall portion 20' of the shell portion 74 and the central elongated rod 26 being provided. with actuating elements 36 defining cooperatively sloping cam surfaces with which actuating members 34 cooperate to push the shell portions 72 and 74 away from each other to the expanded state shown in FIG. 28C.
In FIG. 29A, 29B and 29C, a further embodiment of the tan 10 ™ is shown which has the same shell parts 72 and 74 as illustrated in FIG. 28A, 28B and 28C, as described above and the central elongate core member 26. While in FIG. 28B and 28C, the expansion of the tan being established as a vertical separation by pushing the shell portions away from each other, establishes the second embodiment shown in FIG. 29A, 29B and 29C expand the tan by displacing the shell portions 72 and 74 laterally, as illustrated in FIG. 29B and as obtained by the interaction between activating elements 34 'and 36' shown in FIG. 29C. To be more precise, in FIG. 29B, the shell portion 72 is displaced to the right and correspondingly the shell portion 74 is displaced to the left relative to the central elongate core member 26.

FIG. 32 and FIG. 33 illustrates in more detail a further embodiment 10 ^X of the tan according to the present invention which exhibits the very advantageous features of being composed of no more than three components, namely two identically formed shell parts 72 'and 74' and the central core member 36. The shell parts 72 'and 74' comprise integrally the shell portions 72, 72 and 28 ', 30' of the embodiment 10 ^V of the tan, respectively, the shell portions 72 and 72 and corresponding shell portions 28 'and 30' in the lower and upper portions 12 'and 14' of the tan, respectively. ^VII is constituted by a single integrated component 72 'and 74' respectively. Similarly, the central elongated core member which serves to displace the shell portions 72 'and 74' in a compulsive manner from the contracted or non-expanded state to the expanded state and vice versa serves to engage the actuating elements on the shell portions 72 'and 74'. .
FIG. 34 shows a perspective view of a tine 10 holding a skin 76. The skin 76 is stretched on the tine and secured in the stretched position by a clip 94 adjacent to the tail portion of the skin 76. The clip 94 is positioned over ribs 38 on the tine 10. which ribs 38 cooperate with the clip 94 to retain the skin 76 on the tine 10.
FIG. 35A is a perspective view of the clip 94 of the preceding figure. The clip 94 is a strip of plastic material that is clamped to the skin 76 on the tine 10. The clip 94 is straight when not applied to the tan. The clip 94 comprises a pair of opposed rigid attachment sections 96, 96 ', a pair of opposed flexible sections 98, 98', each of which is connected to a fastening section and a rigid section 90 which interconnect the flexible sections 98, 98 '. The flexible sections 98, 98 'can be easily bent so that the securing sections 96, 96' meet around the taper 10. The securing sections 96, 96 'can be interconnected by a screw or similar via a hole 96. The combination of rigid sections and flexible sections makes it possible possible that the clip assumes a substantially uniform fixation pressure on the skin 76. The clip 94 comprises gripper members 100 spaced apart therebetween and the flexible section 98, 98 'of the clip 94 comprises a greater distance 92 between gripper members 100 to allow that the flexible sections 98, 98 'are slightly bent.
DK 2020 00014 U1
FIG. 35B shows a close-up view of the clip 94. The clip 94 comprises several gripping elements 100 which are intended to face the skin of the tine. The gripping elements 100 define a small distance between these which allow hair to pass in between the gripping elements 100. Each of the gripping elements 100 has a T-shape, i.e. a short and slender element extending outwardly of the clip 94 and a contact element extending parallel to the clip 94 at the outward end of the short and slender element and intended to face the tine 10.
FIG. 35C shows a close-up of the clip 94 and the skin 76. The clip 94 comprises gripping elements 100 with the T-shape facing the tine 10. The T-shape of the gripping elements 100 allows the gripping elements 100 to penetrate the hair 102 'on the skin 76 so that it Inwardly oriented fixation pressures generated by the clip 94 are applied to the leather by the skin 76 and not the hair on the skin 76. Thus, any deformation of the hair 102 'on the skin is avoided.
FIG. 35D shows a close-up view of the clip 94 at the flexible section 98 of the clip 94 which includes rounded gripping members 100 and distances 92 between the gripping members to prevent clamping of the hair 102 on the skin 76 when the flexible section 98 is bent.
FIG. 36 is an image similar to that of FIG. 34, illustrating the skin 76, on which a holding bag 106 is applied prior to the application of the strip to the skin 76.
