    Tan lock with fixatives
    Description
    FIELD OF THE INVENTION
    The present invention relates to a tan latch with fixing means for enclosing and retaining a fur animal skin to a cross section of a tan, wherein the tan latch comprises an inner circumference and an outer circumference, wherein the fixing means comprise at least one extensible first portion and a second portion, wherein the second portion at least partially encloses the expandable first portion on at least portions of the outer circumference of the tuck latch, and wherein the expandable first portion comprises at least a portion of at least one chamber, wherein the at least one chamber comprises at least a filling spout.
    The present invention further relates to a method of using a tan lock with fixing means.
    BACKGROUND OF THE INVENTION
    It is known to retain fur animal skins, such as mink skins for tanners by staples or the like, where the staples are knocked through the skins and secured to the tan made entirely or partially in wood or other material suitable for retaining staples. However, this causes a permanent deformation in the form of holes in the skins, a deformation that becomes elongated perforations in the skins as the skins dry out and contract. In addition, it is a great job to remove the staples from the skins again after drying, and there is also a risk of damaging the hair on the skins during this operation.
    It is also known to pull paper / cardboard down over a tan and then to pull a skin on, then to pull a piece of plastic in the form of a tube down over the skin and finally by clamping the skin and paper / cardboard against the skin. the tan by pulling the plastic bag island
    DK 2018 00220 A1 is entitled to an area on the tan, where the cross-section has a size which causes the plastic bag tube to fit tightly around the skin and thereby fix this to the tan. Instead of a plastic bag tube, alternatively, foil can be wound around a portion of the skin.
    For example, the restraint device may also be a strip (cable tie) or equivalent that can hold the skin to the tan - either directly on the skin or outside of a plastic bag tube. However, this technology and working method entails a constant procurement, handling, assembly, disassembly, further handling and final disposal of both paper / cardboard and plastic. The use of this technology is therefore a constant expense.
    The object of the invention
    The object of the present invention is to provide a tan lock which can be used without the need to make a permanent deformation of fur animal skins from, for example, mink, and which also does not entail ongoing costs for products such as paper / cardboard and plastic, and handling and disposal thereof. .
    It is a further object of the invention to provide a tan lock which encloses the entire cross-section of a tan and at the same time applies a uniform pressure all the way around the tan so that a uniform pressure is obtained on both sides and edges of the tan and on the skin.
    It is further the object of the invention to provide a tan lock capable of retaining a skin to both a conventional solid tan and to a tan of the kind capable of extending the skin's attachment to the tans.
    The object of the present invention is achieved by a tan lock as defined in claim 1 and by a method as defined in claim 10.
    DK 2018 00220 A1
    Preferred embodiments are defined in the subclaims and are explained in the following description and illustrated in the accompanying figures.
    The tan lock according to the invention is a tan lock adapted to enclose and hold a fur animal skin arranged on a tan, the tan lock comprising:
    an extensible first portion adapted to be brought into a configuration wherein the first portion provides a radially inwardly directed force toward the tan, wherein the first portion comprises or is connected to a fluid filling device,
    a second portion enclosing at least partially the extensible first portion and thus providing a radially inward reaction force as the first portion is expanded where the second portion is malleable but not extendable.
    This makes it possible to provide a tan lock that can be used without the need to make a permanent deformation of fur skins from, for example, mink, and which also does not entail ongoing costs for products such as paper / cardboard and plastics as well as handling and disposal thereof. It is further possible to provide a tan lock which encloses the entire cross-section of a tan and at the same time applies a uniform pressure all the way around the tan so that a uniform pressure is obtained on both sides and edges of the tan and on the skin. In addition, it is possible to provide a tan lock capable of retaining a skin for both a conventional solid tan and a tan of the kind capable of extending the skin's attachment to the tans.
    The expandable first part is arranged to be brought into a configuration, the first part providing a radially inward force against the tan.
    Thus, the first part may be made of any suitable material which can be brought into a configuration, the first part providing a radially inward force against the tan.
    DK 2018 00220 A1
    The first part comprises or is connected to a filling device for filling a fluid. In this way, it is possible to fill said fluid into the first portion which is thereby expanded and, as a result, provides a radially inward force against the tan.
    By fluid is meant fluid and / or gas. Fluid may e.g. be atmospheric air or hydraulic oil.
    In one embodiment, the first portion comprises a filling device for filling a fluid.
    In another embodiment, the first portion is connected to a fluid filling device.
    The tan lock comprises a second portion which encloses at least partially the expandable first portion, thus providing a radially inward reaction force as the first portion is extended. Thus, the second portion will prevent the first portion from being pressed radially outward only, but also provides an inward radial force which ensures that the skin is held to the tine.
    However, it is important that the second part is malleable but not extendable. By the wording malleable but not extendable ”is meant that the other part can be formed but not extended. This means that the second part is not extended when exposed to pressure from the expandable part in the same way that a tire is not extended when the hose located in the tire is inflated.
    By using a malleable second part, it is possible for the tan lock to provide uniform pressure against the skin and the underlying tane. By ensuring that the second portion cannot be extended, it is ensured that the second portion provides a radially inward reaction force which causes the first portion to be pressed inwardly against the skin.
    DK 2018 00220 A1
    In one embodiment, the second part is made as a band provided with two fixing areas containing velcro, so that the band, when enclosing the expandable portion, can be secured to itself via assembly / fixing of said fixing areas containing velcro.
    In one embodiment, the first portion is movably disposed relative to the second portion. Hereby it is possible to provide a tan lock where the first part is not limited to being placed at a predefined position relative to the second part.
    In one embodiment of the invention, the first portion is removably attached to the second portion. This makes it possible to ensure that the first part is fixed in relation to the second part.
    It may be advantageous that the first portion and / or the second portion comprise positioning means for restricting the axial movement of the first portion relative to the second portion.
    In this way, it is possible to ensure that the first part and the second part do not move axially with respect to the second part. This means that the second part can be secured in an optimal position relative to the first part. This ensures that the first part provides a force with a predefined (inward) direction.
    The positioning means may be one or more mechanical structures adapted to abut at least one region of the first portion and / or at least one region of the portion portion.
    In one embodiment, the positioning means is an integral part of the first portion and / or portion portion.
    It may be an advantage that the first part and / or the second part comprise one or more fasteners for fastening the first part in
    DK 2018 00220 A1 relative to the second part. Hereby it is possible to fix the first part with respect to the second part so that the first part is placed in a predefined position in relation to the second part and the tan.
    It may be advantageous that the first portion comprises a stud for applying a fluid. Hereby it is possible to introduce a fluid into the first part through said studs.
    In one embodiment, a stud protruding relative to the other portion is used. It may be advantageous for the plug to extend through a hole provided in the second portion.
    It may be advantageous for the second portion to include a studs for applying a fluid. This stud may be part of a stud that also forms part of the first portion.
    It may be an advantage that the second part comprises a stud for applying a fluid, the plug being designed as a separate stud which is only part of the second part. This is a smart solution if the first part is attached (for example, the glue) to the second part and is thus arranged to receive said fluid through a separate studs which are only part of the second part.
    It may be an advantage that the expandable part is more flexible than the other part.
    It may be advantageous that the expandable portion is made of an elastic polymer.
    It may be an advantage that the expandable part is a hose, e.g. and a rubber hose.
    DK 2018 00220 A1
    In a preferred embodiment, the expandable portion is an annular hose, e.g. a rubber hose comprising a circular cross section. The cross section can advantageously be the same along the entire hose.
    It may be an advantage that the other part is made of a canvas material. This makes it possible to provide a functional tan lock for a relatively low price.
    It may be advantageous that the expandable first portion is longer than the second portion. This allows the second part to enclose the first part, which can thus be held in place by the second part.
    In one embodiment, the expandable first portion is permanently fixed to the flexible second portion.
    In one embodiment, the expandable portion comprises multiple connected chambers.
    In one embodiment, the filling nozzle comprises a non-return valve. Hereby it is possible to prevent the fluid from flowing back out of the expandable part.
    The method according to the invention is a method for using a tan lock with fixing means according to the invention, wherein the method comprises at least the following steps:
    A. the tan lock is moved around a tane,
    B. the tan lock is moved around a fur and
    C. the expandable first portion is brought into a configuration, the first portion providing a radially inward force to the tan via filling of a fluid.
    This makes it possible to place the tan lock outside the tan either from the top of the tan or from the bottom of the tan and in the same operation carry the tan lock outside a skin applied to the tan and still in the same handling hold the tan lock
    DK 2018 00220 A1 at the tail end of the applied skin and finally inflate or pump it into at least one chamber, thereby fixing the skin to the tan.
    In an alternative method, it is possible to place the tan lock around the tan either from the top of the tan or from the bottom of the tan and then apply the skin to the tan before the tan lock is placed outside a tan skin and still in the same handling hold the tan lock at the tail end of the applied skin and finally breathe or pump it into at least one chamber.
    Thus, if the skin is applied to the tan before the tan lock is applied, the operator can carry out the entire handling of the tan lock once, whereas the operator must grip the tan lock at least once again, if the skin is not applied to the tan before the tan lock is applied.
    For example, air can be applied by fixing the tan latch to the tan and the air can similarly be re-vented by unlocking the tan latch from the tan, after which the skin can be removed from the tan.
    According to one aspect of the invention, the above-mentioned object is achieved with a tan lock with fixing means, for enclosing and retaining a fur animal skin to a cross-section of a tan, the tan lock comprising an inner circumference and an outer circumference, wherein the fixing means comprise at least one extensible the first portion and a second portion, the second portion at least partially enclosing the expandable first portion on at least portions of the outer circumference of the tuck latch, and the expandable first portion at least forming a portion of at least one chamber wherein the at least one chamber comprises at least one filling nozzle, the tan lock further comprising a first end and a second end, and the second part being a malleable but not extendable part.
    It is possible to use an extensible first part which is fixed to the second part.
    DK 2018 00220 A1
    By the tan lock located in a plane perpendicular to the longitudinal direction of a tan and enclosing a cross section of the tan, the inner perimeter is believed to be the length of the surface closest to the tan. Similarly, the outer perimeter is believed to be the length of the surface furthest from the tan.
    The expandable portion may be a portion which may expand, for example, by breathing air or pumping a liquid either into the portion or in contact with the portion, whereby the expandable portion changes shape and / or size.
    By another part is meant a part which can at least be bent, bent and pressed without the use of tools and which, by ordinary use and influence of the expandable part, will adapt to it. The second part can be essentially as easy to shape as the expandable part, but it is not possible to extend the second part, which will therefore have an unchanged length when the expandable part is filled with e.g. air or liquid, whereby the pressure from the expandable part will thereby lead to an outward pressure on the other part.
    This makes it possible to retain a fur animal skin, such as a mink skin, on a tan without permanent deformation of the skin, as well as to achieve uniform pressure all around the tan, where the tan may be a solid tan or a tectonic one, longitudinally capable of changing shape.
    In one embodiment, the expandable portion may be an endless hose and the other portion a tensile structure which surrounds portions of the hose. The second part may be designed as a strap or a strap. However, the second portion must have a size and shape relative to the expandable portion which allows the expandable portion to be held in a position where the expandable portion expands in the desired direction.
    DK 2018 00220 A1
    In another embodiment, the expandable portion is integrated into the second portion such that a portion of the at least one chamber is constituted by the other portion and a portion of the at least one chamber is constituted by the expandable portion and the expandable portion primarily moves in the direction of the inner circumference and thus during use in the direction of the tan and the skin of the tan. With this embodiment, the expandable portion and the second portion are coherent and easier to handle.
    In a further embodiment, the expandable portion is composed of the other portion such that a portion of the at least one chamber is constituted by the other portion and a portion of the at least one chamber is constituted by the expandable portion and the expandable portion primarily moves in the direction of the inner circumference and thus during use in the direction of the tan and the skin of the tan. With this embodiment, the expandable part and the other part are coherent and thus easier to handle, inspect, repair and replace. This makes it possible to have the expandable part squeezed uniformly all the way around the tan and to feel the same surface pressure on both sides and edges of the tan. This means that a good compressive force can be obtained on the surfaces corresponding to the compressive force on the edges, which is important. In contrast, the surface pressure a strip or elastic will exert is greatest on the edges of the tan and thus least on the sides of the tan.
    The tan lock can be mounted both from the top of a tane and from the bottom of a tane, depending on which procedure is desired during the tanning.
    In one example, an operator may choose to attach the tan and attach the skin prior to mounting the tan lock, and it will therefore be natural to mount the tan lock up from a tan's nozzle end. In another example, an operator may choose to place the tan lock around the pedestal end before attaching the tan and after applying the skin, then mount the tan lock from below the tan pedestal.
    DK 2018 00220 A1
    The tan lock may in a preferred embodiment be designed and adapted to the tan's cross-section so that the expandable portion may have the same distance from the inner perimeter of the tan lock and to the tan's surface, so that the expandable portion extends approximately equally all the way around the tan, and the material tension in the expandable part is essentially the same everywhere. In a preferred embodiment, the distance from the outer circumference of the tan lock to the surface of the tan may, for example, be 15-30 millimeters.
    In a further preferred embodiment, in which at least one chamber is supplied with air, the air pressure is constant in the chamber, the filling nozzle being coupled to a constant pressure supply system. One of the advantages of this is that the air can be supplied to the chamber more quickly and that the pressure will not fall therein at any time. Another advantage is that the air can get out of the chamber more quickly either by sucking it out or simply by removing the overpressure in the system. When the pressure is removed from the chamber, the tan lock is open.
    By air, here is meant any gas or collection of gases, whether the gas is used individually, such as, for example, 100% nitrogen / nitrogen or 100% oxygen / oxygen or whether a mixture of different gases is used in a particular or arbitrary mixing ratio. .
    In one embodiment, the at least one chamber has at least one filling nozzle through which, for example, air can be supplied and discharged. The filling nozzle may be fixed to the second portion from which air is supplied to the chamber. In another embodiment, the filling nozzle may be fixed to the other portion but attached to the expandable portion from which air is supplied to the chamber, in the style of a bicycle hose valve which may be fixed to a rim.
    DK 2018 00220 A1
    In an alternative embodiment, a liquid in the form of, for example, water / oil, can be used to apply pressure to the at least one chamber by pumping the liquid into the chamber.
    In a preferred embodiment, the tan lock comprises several connected chambers. This makes it possible to have one or more chambers on either side of the tan and across the longitudinal direction of the tan, or several parallel chambers located in the longitudinal or transverse direction of the tan. Thus, as long as the chambers are connected, there will continue to be a uniform pressure in all chambers and all the way around the expandable portion, and thus there will also be a uniform pressure throughout the tan.
    In an alternate embodiment, there may be several chambers which are not connected, but each chamber having its own fill plug. Hereby the pressure can be differentiated and, for example, air can be supplied to the individual chambers, until the tan lock is placed exactly right and then the subsequent chambers can be pressurized and inflated. Alternatively, liquid is supplied to the individual chambers until the tan lock is positioned correctly and then the subsequent chambers can be pumped up. The differentiation of the pressure, for example, allows a higher pressure to be obtained on the sides of the tan than on the edges of the tan or vice versa.
    In an alternative embodiment, where there are several chambers not connected to each other, the case where the expandable portion is a hose or elastic material such as rubber may be taken into account. Thus, in such cases there will be a risk of uneven stiffness in the hose, for example a risk of thicker rubber in some places and thinner rubber in other places of the expandable material.
    The surface of the expandable portion may also be with or without friction means / ribs. In a multi-chamber system, it also allows for further differentiation of the pressure. In a system with one or more chambers, the expandable portion provides the surface, for example, equipped
    DK 2018 00220 A1 with friction means / ribs, an opportunity to hold the tan lock to the tan with less pressure than would be the case if the surface of the expandable part was not equipped with friction means / ribs.
    As mentioned, in one embodiment, the filling nozzle of the at least one chamber may be attached to the expandable portion and in another embodiment be fixed to the other portion. In embodiments with multiple filling spigots, these may be attached to the extensible portion and / or may be attached to the other portion.
    The invention is capable of retaining a skin for both a conventional solid tan and for a tan of the kind capable of extending the attachment of the skins to the tans.
    When using so-called stretch tans, it is common to apply the tan locks and inflate / pump them up to 1 bar pressure. When all the tan locks are mounted on the stretch tans, the pressure is then increased simultaneously in all the tan locks.
    In one aspect, the present invention relates to a tan lock in which the expandable portion comprises expansion properties greater than the second portion. By this it is meant that the expandable part expands more than the other part by a pressure.
    The expandable portion may, in one embodiment, comprise varying thicknesses, for example such that the expandable portion is thinnest in the middle. By the center is here meant preferably the area between the first end of the tan lock and the other end of the tan lock, where the expandable part is or may be attached to the second part, and likewise the thinnest part must face towards the inner circumference of the tan lock. This makes it possible to use less resilient materials for the other part of the tan lock.
    DK 2018 00220 A1
    In one aspect, the present invention relates to a tan lock, wherein the expandable portion is an elastic polymer. It is inherently obvious to use an extensible part in an elastic polymer such as a rubber material, the rubber having an expansion coefficient suitable for the purpose and for holding a skin to a tane. Preferably, the tan latch without air also does not have a larger internal circumference than is necessary, that is, the inner circumference of the tan latch without air must, of course, be able to be applied to a tan with a skin, without it being problematic to handle the tan latch.
    The present invention relates in one aspect to a tan lock in which the expandable portion is a hose. As an example of this, the tan lock can only be constituted by a hose having a thick side / other part and a thin side / expandable part. However, the hose may also be fixed to a flexible part which may be straps, the other part of which prevents the expandable part from expanding as much towards the outer perimeter as it does to the inner perimeter where it is naturally in the direction of the inner circumference the tan lock should expand most. This allows the expandable portion to be a hose with a filling nozzle fixed to the other portion.
    In one embodiment, the expandable portion is an integral portion of the second portion and the expandable portion is partially embedded or otherwise a fixed portion of the second portion of the tuck lock. This can be done, for example, by a joint of the second part and the expandable part, where the parts are fixed to one another, such as a hose with a stiff back and another flexible and / or thin front.
    The second portion may at least partially comprise an elastomer, the second portion less elastic than the expandable portion. This allows the desired flexible properties to be supported while at the same time minimizing or completely avoiding the expandable properties on the outer circumference of a tan lock. The second part may be a wide canvas band covering the whole
    DK 2018 00220 A1 the expandable part. The second portion may be a series of straps attached / fixed to the expandable portion.
    Advantageously, the expandable portion may comprise an overlap relative to the second portion. This makes it possible to provide a chamber where the bulk of the surface of the empty chamber is constituted by the expandable portion. This additionally allows for easier inflation of the chamber, the second part preventing the expandable part from expanding as much towards the outer circumference as towards the inner circumference, and where it is towards the inner circumference, the tan lock here will expand most.
    It may be advantageous for the extensible first part to be permanently fixed to the second part. Hereby it is possible to provide a tan lock where the second part is fixed to the expandable part. The purpose of the fixing is to define the possibilities of movement of the expandable part and so that the expandable part is partly held in the desired position relative to the other part and partly that the expandable part expands in the intended direction, which during use of the tan lock is against the surface of the tan.
    This makes it possible to constantly maintain the expandable part in the optimal position with respect to the other part, and so that the tan lock acts as intended all the time and does not entail additional and unintended actions such as manual placement or alignment of the expandable part. relationship to the other part for the tan lock to work.
    A permanent fix can be done by gluing, welding or similar.
    In one embodiment, fixation is used all the way around the other part, where the fixation faces inwards in the direction from the outer perimeter to the inner perimeter and thus in use facing a tane.
    DK 2018 00220 A1
    The fixing may be located such that it is located on either side of the expandable portion and thus towards the first end and / or the second end.
    The expandable portion may be retained to the other portion by adhesive tape, tape or glue, which also causes the expandable portion to be fixed in the optimum position relative to the second portion.
    The fixing may comprise, for example, straps, snaps, or other, such that, for example, the hook portion is secured to the expandable portion and the loop portion is secured to the other portion or vice versa. This also has the advantage that the expandable part can be quickly replaced by leakage / puncture of the expandable part.
    The expandable portion may advantageously comprise multiple connected chambers. This makes it possible to have one or more chambers on either side of the tan and across the longitudinal direction of the tan, or several parallel chambers located in the longitudinal or transverse direction of the tan. Thus, as long as the chambers are connected, there will continue to be a uniform pressure in all chambers and all the way around the expandable portion, and thus there will also be a uniform pressure throughout the tan.
    In an alternate embodiment, there may be several chambers which are not connected, but each chamber having its own fill plug. Hereby the pressure can be differentiated and where, for example, air can be supplied to the individual chambers, until the tan lock is placed exactly right and then the subsequent chambers can be pressurized and inflated. Alternatively, liquid is supplied to the individual chambers until the tan lock is positioned correctly and then the subsequent chambers can be pumped up. The differentiation of the pressure, for example, allows a higher pressure to be obtained on the sides of the tan than on the edges of the tan or vice versa.
    DK 2018 00220 A1
    In an alternative embodiment, where there are several chambers not connected to each other, the case where the expandable portion is a hose or elastic material such as rubber may be taken into account. Thus, in such cases there will be a risk of uneven stiffness in the hose, for example a risk of thicker rubber in some places and thinner rubber in other places of the expandable material.
    The surface of the expandable portion may also be with or without friction means / ribs. In a multi-chamber system, it also allows for further differentiation of the pressure. In a system with one or more chambers, the expandable surface, for example, equipped with friction means / ribs, provides an opportunity to hold the tan lock to the tan at a lower pressure than would be the case if the surface of the expandable part was not equipped. with friction agents / ribs.
    It may be advantageous that the filling nozzle includes a non-return valve. This makes it possible, for example, to use an air filling system which does not have to carry a constant pressure for a long period, which is necessary to be able to maintain the pressure in the used tan locks and thus secure the tan locks' locking function. Thus, by using check valves in the tan locks, the air filling system must ensure the necessary pressure during the installation of the tan lock, after which the system is optimally no longer necessary to maintain the lock function of the tan lock. The valve can, for example, be a traditional Schrader valve, which is known from automobiles etc.
    In practice, however, it may be necessary to regulate the pressure in at least one chamber during locking in the event of a possible pressure drop, and thus the non-return valve may also open in case of replenishment or control of pressure in the at least one chamber. The check valve can advantageously be arranged to be opened by unlocking the tan lock and thus by discharging, for example, the air supplied to the at least one chamber.
    DK 2018 00220 A1
    Thus, should a power failure or other breakdown occur, it does not affect the tan locks that are locked, for example the air cannot even come out of a non-return valve.
    The expandable portion may be fixed to the second portion, substantially at least one of the first end and the other end. This makes it possible to fix the expandable portion to the second portion substantially at the first end and / or the second end, but also at least partially along the circumference of the tan lock, for example along the inner circumference and / or the outer circumference. . With such fixation, there is no displacement between the parts and it is ensured that the extension of the tan lock occurs in the right direction.

    Detailed description
    Initially, it should be noted that the accompanying drawings illustrate non-limiting embodiments only. A variety of other embodiments will be possible within the scope of the present invention. In the following, similar or identical elements in the various embodiments will be denoted by the same reference numeral.
    FIG. 1 shows a tan lock 1 in an embodiment seen in perspective, showing that the tan lock 1 comprises an expandable part 2 which is partially enclosed by another part 3. The other part 3 is malleable but cannot be extended. The tine lock 1 has an inner circumference 4, which is made up of the expandable part 2, and an outer perimeter 5, which is essentially the second part 3. From Figure 1 it can be seen that the tan lock 1 has a filling nozzle 6 which is connected to the a chamber (not shown).
    The outer circumference 5 further comprises a first side 7 and a second side 8, as well as a first end 28 and a second end 29. The expandable part 2 is essentially only able to expand inwardly when, for example, air is supplied to the chamber. (not shown) through the filler neck 6, thereby reducing the internal circumference 4. It is also substantially the inner circumference 4 that becomes larger when, for example, air / liquid is pumped / sucked out of the chamber (not shown) through the filling nozzle 6.
    FIG. 2 shows a tan lock 1 seen from one end 28. It is clearly seen what constitutes the inner perimeter 4 and what constitutes the outer perimeter 5.
    The expandable portion 2 may be fixed to the other portion 3 by means of fixing means (not shown). Thus, the expandable portion 2 will not be able to move beyond the boundary corresponding to the outer circumference 5 bounded by the second portion 3.
    DK 2018 00220 A1
    Alternatively, it is possible to leave the expandable part 2 slidably mounted relative to the second part 3.
    The latch lock 1 comprises an expandable part 2 which is enclosed by the second part 3 which is malleable but cannot be extended.

    29. The expandable portion 2 comprises a chamber 20 and a chamber 20 '. The expandable portion 2 may be attached to the second portion 3 at either the first end 28 and / or the second end 29.
    The chambers 20, 20 'of the expandable portion 2 may be connected or separated and different pressures may be provided in the chambers 20, 20'. The expandable portion 2 is fixed to another portion 3 an inner circumference 4, while the other portion 3 constitutes an outer circumference 5.
    FIG. 10A shows a cross-section of a tan lock 1 according to the invention mounted on a tane 19. The tan lock 1 comprises an expandable part 2 formed as a rubber hose, which is enclosed by another part 3 which is malleable but not extendable. The expandable portion 2 comprises a chamber 20.
    FIG. 10B shows the one shown in FIG. 10A, in an inflated configuration in which a fluid (liquid and / or air) is introduced into chamber 20. The expandable portion provides an inward force against the tan 19. Thus, the tan latch 1 is adapted to hold a fur animal skin applied to the tan. 19. The second part 3 ensures that the expandable part 2 cannot expand outwardly once the volume of the expandable part reaches a level corresponding to the volume enclosed by the second part. In this way, the expandable part is forced to expand in an inward direction towards the tane 19.
    FIG. 11A shows a cross section of another tan lock 1 according to the invention mounted on a tane 19. The tan lock 1 corresponds substantially to that of FIG. 10A, except that the expandable portion comprises a filling nozzle 6 extending from the expandable portion 2 through an opening in the second portion 3 so that the filling nozzle 6 is accessed from the outside of the second portion 3.
