    Description: The invention relates to a device for cutting elastic coverings, in particular floor coverings, such as luxury vinyl tiles (LVT), and / or coverings of textiles, cork, rubber, rubber, linoleum, polyvinyl chloride (PVC) and / or other Plastic, according to the preamble of claim 1.
    When laying such coverings, it is regularly necessary to tailor the individual covering elements of the covering. The cutting of the covering elements of such coverings places high demands on devices that are used for cutting the coverings. On the one hand, the material of such floor coverings should be as resistant as possible, i. firm and tough, his. At the same time as clean as possible cuts should be carried out to get the most possible closed floor surface when juxtaposing the cutted pieces. In this case, such devices should be used when laying the floor on site, which means that exist in terms of size and weight of such devices limitations.
    A device of the type in question is disclosed in EP 2 298 513 A1. The device has a base, which provides a support surface for supporting the covering or covering element to be cut. For cutting the covering or covering element, a blade is provided, which can be moved by suitable guide means with its cutting edge on to the base. The guide means are arranged on both sides of the blade in a vertical plane with the cutting edge. The guide means are connected by brackets to the base. In order to apply the forces necessary for cutting the covering or covering element to the blade, an actuating device is provided. This has a lever to be able to exert sufficiently high forces on the blade on the covering or the covering element. The brackets serve as an abutment to absorb the reaction forces resulting from the forces exerted by the lever mechanism on the blade for cutting the pad forces.
    A disadvantage of a device of the type described is that by the arranged on both sides of the cutting brackets or guide means the dimension of the lining, which can be included for cutting in such a device is limited. In particular, this means that lining sections or elements with such a device can not be cut along edges which exceed a certain length. In order to enable on-site cutting with such a device, the covering must already be present in sections or covering elements whose edge lengths do not exceed the length predetermined by the device. Rectangular lining sections, which have different lengths of edge lengths, can usually only be cut along their shorter edges.
    The object of the invention is to provide a device for cutting elastic coverings available, which has a greater flexibility in terms of possible patterns and yet has a compact design and low weight.
    The object is achieved by a device having the features of claim 1. The features of the dependent claims relate to advantageous embodiments.
    In the apparatus of the type mentioned is provided according to the invention that the device is designed such that the coating can protrude during cutting in extension of the cutting edge on the outside of the holder. As far as the term "lining" is used in the following, not only the covering as such, but already a single covering element or a plurality of covering elements for a covering meant. By the above-mentioned inventive design of the device, it is possible to perform cuts along the edges of elastic coverings, even if the edges of the elastic coverings are longer than the width of the cutting edge or the width of the area below the cutting edge, which is limited by the holder , In order to cut a covering with the inventive device, the edge length is greater than the length of the cutting edge, it is only necessary to move the coating on the support surface and make an extension of the already performed section one and optionally a plurality of further cuts. Of course, it is understood that coatings or flooring elements can be easily cut on their short sides with the inventive device.
    While in conventional known devices, the holder, in particular for reasons of better rigidity, is arranged in the vertical plane of the blade, the effect is exploited in the inventive device that - as has been surprisingly found - it is possible, a sufficient To ensure rigidity of the overall construction, without placing the bracket directly in the vertical plane of the cutting edge.
    Structurally, the design of the device for cutting elastic coverings is made possible in particular by the fact that the device has a free space for receiving the covering. This free space is preferably arranged between the holder and the base and / or between the guide device and the base. In this case, the free space is in particular on the level of the support surface and preferably in extension of the blade. Due to the free space, it is possible to arrange covering elements whose length is significantly greater than the length of the blade, on the support surface and cut. During the cutting of an elongate covering element on its long side, it is then partially on both sides, d. H. on the two side surfaces in extension of the blade, on the inventive device via.
    In order to allow that also paving strips can be easily cut with a certain width, the support surface has a corresponding sufficient width and the free space a corresponding sufficient depth of at least 5 cm, in particular of up to 50 cm on. Each individual value of the depth of the free space within the aforementioned interval is basically possible.
    The free space can be realized in particular by a recess in the holder. The holder then has a cross section with an opening arranged in extension of the cutting edge. Depending on the construction of the bracket and base, and more particularly depending on the arrangement of the connection between the bracket and the base, the opening may also be bounded by the bracket and a portion of the base connected to the bracket.
    Preferably, the holder has a C-shaped cross-sectional area when viewed longitudinally along the cutting edge. A C-shaped cross-sectional area is to be understood in particular as meaning a cross-section which defines a free space open to one side, which is bounded in the vertical direction by the holder. Depending on the arrangement of the connection between the holder of the base, it is also possible and advantageous that the C-shaped cross section is defined by the holder and a portion of the base connected to the holder.
    It is understood that in the above and following example described arrangements of component connections between the holder and base, the invention is in no way limited to these types of embodiment. In particular, it is of course also possible to form brackets and base in one piece or parts that are assigned due to their function and / or constructive arrangement of the base to form integrally with the holder.
    It is particularly advantageous if the inventive, the protrusion of the covering on the outside of the holder enabling configuration of the device is realized on both sides in extension of the cutting edge. In this case, a symmetrical design is possible, which has the advantage that right and left-handers find the same conditions in terms of usability.
    In addition, a quite possible asymmetrical design of the inventive device has the advantage that the device can be optimized in terms of their combination of rigidity on the one hand and on the other hand, the ability to handle as diverse cutting tasks. Thus, for example, a holder C-shaped and the holder along the cutting edge can be designed lying in a conventional manner in the plane of the cutting edge.
    Preferably, the support surface is expandable. This concerns in particular the area of the support surface in extension of the cutting edge. The protruding during cutting over the outside of the bracket portion of the pad can be supported in this way, which means advantages in handling. Especially if the coating should protrude far beyond the outside of the holder, it is advantageous to provide the coating an additional support surface in extension of the cutting edge available.
    It is particularly advantageous that the concept of expandability of the support surface leads only temporarily to the broadening of the device, namely, when the support surface is in the expanded state. In terms of design, this can be achieved, for example, by means of a supplementary module, which can be detachably connected to the base. Such a supplementary module can then be mounted only on demand to the device. If the supplementary module is no longer needed, it can be disassembled at any time. This prevents the supplementary module disturbing, for example, during transport of the device affects. Instead of a separate supplementary module, which is mountable to the device, it is also possible in principle at the base, d. H. on the side surfaces, each to provide a folding wing, which can be fixed in the folded state. The top of the flap then widens or enlarges the support surface. The folding wing can be folded out if necessary and determined accordingly. If the folding wing is not needed, it can then be folded down, so that it then rests with its underside on the side surface of the base. In this way, results in a space-saving arrangement.
    In order to ensure a simple and inexpensive construction of the inventive device, it is advantageous if the base has at least one rail, in particular an aluminum profile rail. The use of profile rails enables a light and rigid construction of the base. In addition, in profile rails are relatively inexpensive components, which has a correspondingly positive effect on the manufacturing cost of the inventive device.
    Furthermore, it is advantageous that such a rail can be equipped with a groove or a similar connecting element or receiving means. These fasteners allow for a simple connection of the rails with each other, on the other hand, the attachment of other components of the device to the rails in a simple way possible.
    In particular, the connection between the holder and such profiles can be designed stiff yet lightweight and easy to install. For this purpose, the holder may preferably have a complementary configured for profiling the rail connecting area. This can be brought into engagement with the rail, for example, on the rail, preferably the front side, pushed or pushed into the rail. Preferably, it is then possible to secure the holder to the rail by a detachable component connection, such as a screw.
    The bearing surface can also be realized in an advantageous manner in conjunction with a rail. The device preferably has a planar element forming the support surface. For example, this can be a sheet metal. Advantageously, a profiling for receiving the planar element is provided on a rail. In this case, two profile rails are preferably arranged on mutually remote sides of the planar element. These profile rails preferably run parallel to one another and / or at right angles to the cutting edge. The interconnected rails then ultimately form a support frame for the base of the inventive device. Such a structure of the base, moreover, advantageously allows the construction of different sizes of the inventive device. In particular, different surface dimensions of the support surface can be realized in a simple manner. The profile rails can be cut to the required length. The flat element can be cut out of flat semi-finished products or cut to size.
    It is understood that the idea of the construction of the inventive device using profile rails and flat elements is not limited to the structure with two externally arranged on the planar element profile rails. It is of course possible that the planar element projects beyond the profile rail, it is also possible that at least one further rail, in particular for reinforcing or stiffening of the base, is provided.
    Another advantage of the use of rails is that, for example, by a groove provided in the rail, a simple if necessary extension of the support surface is possible by supplementary modules.
    Preferably, the base has a stop for horizontal alignment of the lining. Such a stop is arranged in particular on the support surface and / or in the region of the support surface. The stopper is preferably oriented parallel and / or at right angles to the cutting edge, wherein a plurality of stops may also be present.
    Such a stop initially facilitates the horizontal positioning or alignment of the covering to be cut relative to the cutting edge. In this case, the stop is preferably adjustable and / or detachable. In particular, adjustable stops or releasable stops, which can be attached to the device at various positions, have the advantage of allowing a plurality of different possible orientations of the lining relative to the cutting edge.
    A stop is particularly advantageous when a plurality of blanks of the same dimension should be made one behind the other. In such a case, the stop can be adjusted once or mounted in the desired position so that it specifies the correct position of the pad for the cutting task to be repeated, after which a plurality of pads are cut sequentially in series.
    To reduce material tensions in the lining during cutting, in particular, the support surface has a step or bevel following the cutting edge, behind the cutting edge in the depth of the free space. By this step / bevel it is possible that the coating tilts during cutting or angled along the cutting edge.
    Since the blade penetrating into the covering thickened away from the cutting edge, the covering material in the immediate vicinity of the section of the blade penetrating into the lining must avoid the penetration depth. This creates stresses in the material. It is desirable, for example, to avoid plastic material deformation in the region of the cuts, to keep these stresses as low as possible.
    Characterized in that the device is designed such that the coating can angle during cutting along the cutting line, the coating can yield and evade the stresses resulting from the cutting process, so that plastic deformation can be avoided or at least reduced.
    The inventive device advantageously has a stop element on the bearing surface on which the cutting edge comes to rest at the end of its cutting movement. This stop element is preferably made of a material which is strong enough to support the lining to be cut against the pressure of the cutting edge. At the same time the stop element should not be too hard at the same time as a too hard stop element would quickly lead to a blunt cutting edge. The stop element may be made of PVC, for example. It is preferably designed so that it is provided as an insert in a corresponding recess in the support surface.
    With a view to a clean completion of the cutting process, it is desirable if the cutting edge has the most exact possible parallelism to the surface at which it comes to rest at the end of the cutting process. To ensure this parallelism, an adjustment device is preferably provided. With this, the parallelism between the cutting edge on the one hand and the support surface or the stop element on the other hand can be ensured. Alternatively, it is basically also possible for the cutting edge to be deliberately arranged at a very acute angle to the support surface, so that the covering piece located below the cutting edge is not cut simultaneously but only as the cutting depth increases over the length of the blade. Also, for setting such an acute angle, the adjustment device may be provided.
    With the inventive device, it is possible to perform cuts that are longer than the cutting edge. For this purpose, after a successful cut, the material is displaced along the cutting edge, so that the cutting edge can make a further cut, which adjoins the first cut in an extension. In this way, the long section is assembled in sections.
    For carrying out such cuts, it is advantageous if the blade is designed at least in the region of one of its ends in the longitudinal direction such that the material thickness of the blade is reduced towards the end of the cutting edge. This applies in particular to the thickness of the blade in the area of the cutting edge. As a result of this measure, stresses which arise when the blade or the cutting edge ends when the lining is cut in the covering are reduced in the material of the lining.
    In a conventional blade with increasing depth of penetration of the blade in the covering the immediately adjacent to the end of the cut material of the lining is locally stretched. This can lead to plastic deformation of the material, which are visible in the worst case in laid pavement. An advantageous blade formed at its end in the longitudinal direction with reduced material thickness reduces this stretching of the material.
    The reduction of the material thickness of the blade is preferably achieved in that in the region of the end of the blade, a further cutting edge is ground to the blade or is. This preferably runs at right angles or at least substantially at right angles to the cutting edge.
    Preferably, a return element for moving the cutting edge away from the base is provided. This is located above the extension of the cutting edge. By the arrangement of the return element above the extension of the cutting edge, the return element is in the plane of movement of the cutting edge. As a result, a tilting of the device is prevented in the cutting movement, since the forces of the return element act in the plane of movement of the cutting edge. The restoring element is preferably a compression spring. But it is also possible to provide a tension spring. The advantage of a compression spring lies in the fact that a tilting of the blade or the blade holder is avoided by the introduced forces of the return element. Advantageously, the restoring element is arranged above the free space, so that the free space arranged below the return element for inserting the covering to be cut is available.
    Insofar as values and / or ranges of values are mentioned, all individual values and ranges of values lying within the value ranges are expressly mentioned and are regarded as advantageous embodiments of the invention, without requiring an explicit mention of these values or value ranges in the individual case.
    The present invention will be described in more detail by the following preferred embodiments. However, the invention is by no means limited to the preferred embodiments.

    The embodiment of a device according to the invention shown in FIG. 1 has a base 1. At the top of the base 1 is the support surface 2. On the support surface 2, the pad 3 can rest. In the present case, "lining 3" means a separate lining element for creating a lining. For cutting the lining 3, a blade 4 with a cutting edge 5 is provided. The blade 4 is ground on one side in the example shown. Basically, the use of both sides sanded blades is possible. The use of blades ground on both sides can then have advantages if a more even distribution of the material stresses and upon penetration of the blade 4 into the lining 3 is desired. This can contribute to preventing or reducing plastic deformation of the covering 3 by the penetrating blade 4.
    The base 1 is made of profiled rails 6, which extend in the example shown at right angles to the cutting edge 5, and formed between the rails 6 planar element 7 in the form of a sheet. In Fig. 1 is a partial section l-l through the device to illustrate the structure of the base 1 of profile rails 6 and a sheet-like element 7 is shown.
    The cutting movement of the blade 4 is made possible by guide means 8. At the guide means 8, the blade holder 9 is slidably received with the blade 4 received therein. The guide means 8 are connected by brackets 10 to the base 1. The brackets 10 in turn are connected to the base 1 such that portions 14 of the brackets 10 are disposed between connecting profiles 11 of the rails 6 and fastened by fasteners 12 to the rails 6. Through the connection profiles 11, the brackets 10 receive a resilient support on the base 1, so that the reaction forces arising during cutting of the covering 3 can be introduced via this rigid component connection through the brackets 10 in the base 1 and from there into the ground.
    The brackets 10 shown in Fig. 1 have between their connections with the guide means 8 and their connections to the base 1 has a C-shaped cross section when viewed in the longitudinal direction of the cutting edge 5. In this case, the regions 14 of the holders 10 connected to the profile rails 6 close in the direction along the profile rails 6 to the lower part of the C-shaped regions 13 of the holders 10. Due to the C-shape of the brackets 10, it is possible that the covering 3, as can be seen in particular in Fig. 3, protrude beyond the respective outer sides of the brackets 10.
    As can be seen in Fig. 2, a parallel to the cutting edge 5 extending transverse profile 15 is provided in the region of the base 1. At the top of the transverse profile 15 is a stop element 16 made of PVC, which serves as a stop for the cutting edge 5 when cutting the lining 3. The cross profile 15 also has a chamfer 17. The chamfer 17 allows the pad 3 to bend along the cutting line. The resulting in the area of the cutting line in the lining 3, by the cutting edge 5 away increasingly broader blade 4 generated during their penetration into the lining 3 material stresses are reduced.
    It can also be seen in FIG. 2 that the blade holder 9 has a chamfer 18. The bevel 18 allows a better observation of the cutting process by allowing a better view of the blade 4 penetrating into the lining 3.
    The device according to the invention is preferably expandable by the supplementary module 19 shown in FIG. The supplementary module 19 causes an extension of the support surface 2 in extension of the cutting edge 5. In this case, the supplementary module 19 is preferably detachably connected to the device, in particular to the base 1 of the device. In order to enable this releasable connection, corresponding connecting elements 20 may be provided on the base 1, in particular on the profiled rails 6. These may be grooves in the profile rails 6, which are suitable for receiving nuts, for example.
    Advantageously, the blade 4 at one or both ends of the cutting edge 5 with a further cutting edge 21 which is perpendicular to the cutting edge 5, equipped. This further cutting edge 21 serves to reduce material tensions in the pad 3 by the penetrating blade 4 when the pad 3 is merely cut by the blade 4, i. the cutting line in the material of the covering 3 ends.
    It may also be useful beyond the blade 4, as shown in Fig. 3, form over the approximately entire width of the device. For example, while the blade 4 shown in Fig. 3 extends almost over the entire working area between the brackets 10, it would also be possible to use a blade 4 which extends over only half or another part of this working area. In this context, it would also be conceivable to provide interchangeable blades. These shortened blades 4 would allow more pattern variations. Shortened blades 4 can be used particularly advantageously in the device according to the invention if strip-like lining sections 3 are to be merely transversely cut, or at least substantially cut transversely to their longitudinal extent, but not severed.
    In order to facilitate the correct orientation of the pad 3 on the support surface 2, the device according to the invention preferably has a stop 22. The stop 22, shown schematically in FIG. 1, extends parallel to the cutting edge 5. However, the orientation of the stop 22 can also take place in another direction, for example at right angles to the cutting edge 5.
    It is particularly advantageous if the stopper 22 is detachably connected to the inventive device. For this purpose, for example, receiving means 23, such as e.g. Grooves, be provided in the rails 6. However, other arrangements and / or designs of such receiving means 23 for the stop 22 on the device are possible. Thus, for example, the flat element 7 have slots through which for fastening the stopper 22 in the region of the support surface 2 corresponding releasable fasteners, such as screws, can be performed.
    An advantage of the arrangement of the stopper 22 in the region of the support surface 2 and the planar element 7 is in particular that the stop 22 can be arranged in the region of the support surface 2 transversely to and along the cutting edge 5 at any angle to the cutting edge 5. This allows miter cuts, for example. It is particularly advantageous if the receiving means 23 in the region of the support surface 2, which may be in particular slots or grooves, are curved, to arrange a positioning of the stopper 22 optionally at different angles to the cutting edge 5 on the support surface 2 to be able to.
    For the implementation of clean cuts, it is in the illustrated embodiments so that an exact parallelism of the cutting edge 5 to the support surface 2 and the stop element 16 is provided. For this purpose, at least one adjustment device 24 is provided. The adjusting device 24 is an adjusting screw in the example shown. This interacts with the actuating device 25 of the device shown by way of example. The device according to the invention shown by way of example has, as shown in FIG. 3, two adjustment devices 24. Alternatively, it would also be possible to provide only one adjustment device 24.
    The actuator 25 cooperates with the guide means 8 and the blade holder 9. In the example shown, the actuating device 25 is formed as a combination of an eccentrically mounted on the guide means 8 axis 26 and two provided on the axis 26 pressure plates 27. In principle, another number of thrust washers 27 could be provided or the axis 26 could interact directly with the blade mount 9. However, the use of the pressure plates 27 entails the advantage that the contact surface between the blade holder 9 and the pressure plates 27, which is relatively rich, is smaller than would be the case if the axis 26 interacted directly with the blade holder 9 over the entire width of the device.
    In the apparatus exemplified in Fig. 3, a plurality of receptacles 28 are provided for an unillustrated actuator to improve the operability. The actuating element may be, for example, a lever. In the simplest case, the receptacles 28 are holes into which the lever can be inserted. Preferably, a plurality of receptacles 28 in a direction parallel to the cutting edge 5 along the actuator 25 are arranged distributed. The actuating element can then optionally be arranged in different positions along the actuating device, depending on how the current operating situation requires it. In this way, for example, the different ergonomic needs of right and left-handers are taken into account.
    Also advantageous with respect to the handling of a device according to the invention is when a transport device 29 is provided. This can for example have roles. These can, as shown in Fig. 1, be arranged on the holder 10, but it is also an arrangement in the region of the base 1, as shown for example in Figs. 4a to 5, possible. Since during the laying work on a floor covering, the cutting work on a covering section or element expediently take place as close as possible to the intended place of laying the floor, it makes sense to use such a transport device 29 to move the device in a power-saving manner. Assuming that the weight of a device according to the invention is, for example, about 20 kg, the transportation device 29 results in a considerable reduction of the physical load during the movement of the device in the area of the floor surface to be worked. In addition, a good transportability of a device according to the invention, of course, also makes sense in the context of the arrival and removal to the respective site.
    The embodiment shown in Fig. 1, due to the C-shaped configuration in the holder 10 and thereby resulting below the guides 8 free spaces between brackets 10 and guides 8 on the one and the base 1 and the support surface 2 to the other the greatest flexibility among the embodiments shown with regard to the various possibilities to protrude a covering 3 to be cut out of the device. In contrast, the embodiment shown in FIGS. 4 a and 4 b due to the bow-shaped design of the region 31 of one of the brackets 10 has a restriction on the placement of a covering 3 to be cut on the support surface 2. Although the covering 3 may protrude laterally beyond the outside of the holder 10 through the opening defined between the base 1 and the bow-shaped region 31, the dimension of the lining 3 is in the direction transverse to the cutting edge 5 through the connection of the region 31 with the holder Base 1 limited.
    In order nevertheless to ensure as versatile as possible usability of the device, the device shown in FIGS. 4a and 4b is designed asymmetrically. In concrete terms, this means that one of the holders 10 has the described bow-shaped region 31, while the opposite holder 10 has a C-shaped region 13. The C-shaped region 13 is preferably supplemented by a further region 33 for stiffening the holder 10. This construction is intended to ensure that the device has a comparable rigidity in the region of both holders 10. In this case, in the case of a bow-shaped portion 31 by the bow shape, a higher rigidity can be achieved at a lower weight. This must then be compensated for by larger material thicknesses or corresponding areas 33 for stiffening in the case of the C-shaped holder 10 on the other side of the device. In this respect, the device shown in FIGS. 4a and 4b represents a compromise between versatility and weight-stiffness ratio.
    The embodiment shown in Fig. 5 finally has on both sides of the device depending on a holder 10, each having a bow-shaped portion 31. The bow-shaped regions 31 define together with the base 1 in each case an opening 32 on the respective side of the device, through which the lining 3 in extension of the cutting edge 5 can protrude beyond the outside of the holder 10. The bow-shaped portions 31 of the brackets 10 in this embodiment limit the possible dimensions of the pad 3 in the region of both sides of the device. As a result, the exemplary embodiment illustrated in FIG. 5 has the lowest versatility with respect to the possible covering dimensions and cutting patterns compared to the other exemplary embodiments, but the best ratio between weight and rigidity.
    An embodiment with an advantageous return element 34 is shown in Fig. 6. The return element 34 is arranged above the extension of the cutting edge 5 on the guide device 8 and formed as a compression spring. By virtue of this arrangement and the design as a compression spring, tilting of the blade holder 9 and of the guide device 8 is advantageously avoided on account of the forces exerted by the restoring element 34. This is due to the fact that the force introduction of the return element 34 and the guidance of the blade 4 by the blade holder 9 in the same plane of movement. As shown, the device according to the invention preferably has an abutment element 35 which serves as an abutment for the restoring force exerted by the restoring element 34. In addition, a portion 36 of the blade holder 9 is formed so that it receives the restoring force of the return element 34.
    In the example shown, the region 36 is advantageously detachably connected to the blade holder 9, as indicated in FIG. The releasable connection can be realized by means indicated in Fig. 6 by dashes connecting means 37. Due to the releasable connection between the area 36 and the blade holder 9, it is possible to remove the area 36 from the blade holder 9 for assembly or disassembly purposes.
    The blade holder 9 with the region 36 extends along the guide device 8 over a height which is large enough to order the return element 34 in the region of this vertical extent can. Advantageously, the abutment element 35 can be arranged in the region of this height extension. This makes it possible to arrange a compression spring above the extension of the cutting edge in the plane of movement of the blade 4 and the blade holder 9 without the restoring element and / or the abutment member 35 claimed space below the blade holder 9, which is at the expense of the free space 30 available space would affect.
