Description

The invention relates to a holding device with the features of the preamble of claim 1 and a profile for receiving the aforementioned holding device.

The flat materials can be, for example, cloth, fabric, cloth or the like. Devices of this type are used, for example, in the field of advertising technology, trade fair construction and interior design, in which the flat materials to be clamped, which are connected to a clamping frame by a holding device, are used. In the field of trade fair construction and interior design, for example, partition walls, stretch walls and soundproofing walls can have the aforementioned construction and this technology is also used in the field of advertising technology for the production of advertising surfaces.

Holding devices for flat materials and the respective carrier profiles are known from the prior art. For example, construction methods are widespread that allow the tensile stress of the flat materials through textile or flat piping and piping profiles. The latter are profiles with a recess to accommodate and hold the so-called piping. In particular, the welts are sewn, riveted and/or glued to the flat materials and incorporated into the welt profiles that form the frame or are formed on it.

However, this type of construction has some disadvantages since, for example, the cutting operation of the sheet material and the connection of the piping to the latter must be carried out with great precision. If you don't pay attention to the right frame dimensions in terms of construction, either the flat material sags or the piping cannot be pressed properly into the frame because of the excessive tension. A resulting disadvantage is that the flat material is only cut to a specific frame size and therefore cannot be reused on a different frame size. In addition, this construction has the disadvantage that the connection process for both textile and flat piping on the flat materials is cumbersome, time-consuming and costly. The piping must first be sewn, riveted and/or glued onto the flat materials, for example using industrial machines, which leads to the above-mentioned disadvantages of the products known in the prior art.

A generic holding device is known from U.S. 5,584,461 A1 , in which flat materials are arranged between the hook end points.

A generic profile is known from Carrier profile is known from DE 10 2005 005 443 A 1. Against this background, it is the object of one embodiment of the invention to at least partially overcome the disadvantages of the prior art.

This object is achieved by a holding device in which the outwardly directed surface of the second hook-shaped closure comprises a structured surface at least in sections, such as provided by longitudinal ribs or corrugations, which increase the frictional resistance on the outer surface.

Accordingly, the invention relates to a holding device for flat materials, which has a predetermined longitudinal extent. The holding device cross-section, i.e. the cross-section which is perpendicular to the longitudinal extension, has two legs which are arranged essentially parallel or obliquely to one another and spaced apart from one another. The legs are connected to one another at an end portion and form an internal volume. The latter is also referred to below as the receiving volume, since the flat material is preferably at least partially received in the receiving volume. The end section of the two legs, which is not involved in the connection, has a hook-shaped termination. The two terminations are arranged facing each other such that the tip of one termination, hereinafter referred to as the first termination, faces a surface of the other hook-shaped termination, hereinafter referred to as the second termination. In particular, the surface of the second termination on which the tip of the first termination is directed faces outwards with respect to the containment volume and is hereinafter referred to as the surface.

Preferably such surfaces are located opposite the tip of the first hooked termination. Preferably, this area increases the contact area and thus the static friction between the surface of the second termination and the sheet material. In particular, the structured surface is made possible by ribs or waves, but also by roughness or elevations or uneven elevations, which can preferably also run parallel to the longitudinal extension of the holding device. The structure increases the frictional resistance at the surface and thereby improves the clamping of the sheet material between the surface of the second termination and the tip of the first termination.

With the arrangement of the tip of the first hook-shaped termination on the surface of the second hook-shaped termination, a clamping of a sheet material which is clamped between the aforementioned tip and the surface is made possible. The holding device can be made entirely or at least in sections from resilient or elastic material, in particular from plastics (rubber, polyvinyl chloride, polypropylene, or the like) or from an elastic metal such as aluminum.

The planar materials can include flexible, printable, backlit, translucent, transparent, sound-permeable and/or sound-absorbing materials. The materials may then comprise a textile such as cloth, fabric, cloth or the like, or a plastic such as foil or the like.

It proves to be advantageous if the connection between the two legs is straight, arcuate, wavy or jagged and in particular provides a flexible distance between the two legs.

The connection between the two legs should provide a flexible spacing. In particular, the shape of the connection area should increase the flexibility of the holding device in order to improve the insertion and/or the clamping of the sheet material. In particular, the connection area can be straight, curved, wavy or jagged.

The relative dimensions of the two hook-shaped terminations can vary and thus improve the gripping of the sheet material. For example, the length of the arc of the hook, hereinafter also referred to as the bending length, of the second hook-shaped termination can be greater than the bending length of the first hook-shaped termination. This arrangement increases the elastic force directing the tip of the first termination to the surface of the second termination. Thus, the force clamping the sheet material between the tip and the surface is also increased. The shape and/or the special structural features of the second hook-shaped termination can also improve the clamping of the flat material. For example, the starting point of the second hooked termination may be directed outwardly with respect to the containment volume and thus the second hooked termination flexes back on itself. With this arrangement, the elastic force directing the tip of the first termination to the surface of the second termination is increased.

It proves to be advantageous if the outwardly directed surface of the second hook-shaped termination provides a substantially flat surface at least in sections.

In addition, it proves to be advantageous if the bending length of the second hook-shaped termination is greater than the bending length of the first hook-shaped termination. In such a case, the adjustability of the device for clamping the flat material is increased.

In one embodiment of the holding device it is provided that at least one leg has at least one latching element on the outwardly directed surface in relation to the receiving volume for interaction with a receiving element, in particular for locking the holding device in a receiving element.

The at least one latching element can be designed as a projection which extends transversely to the direction of longitudinal extension of the leg with the first termination and/or of the leg with the second termination and forms a rear grip with the receiving element in the direction of longitudinal extension. The latching element can have an arcuate, elliptical, rectangular or arrow-shaped cross section.

The receiving element can have a recess that corresponds to, in particular, is complementary to the latching element and in which the latching element can be arranged.

In order to prevent or at least prevent the second hook-shaped closure from buckling, one embodiment of the holding device provides at least one anti-buckling device which can be or is arranged in or on a recess in the second hook-shaped closure in the form of a bay or loop and which prevents the second hook-shaped closure from deforming Closure counteracts or at least limits this, wherein the recess of the second hook-shaped closure is arranged on a side facing away from the outwardly directed surface of the second hook-shaped closure, is outwardly bounded essentially by the second hook-shaped closure and is open in the direction of the storage volume.

In a further development of the last-mentioned embodiment, the anti-buckling means can include an addition of material to the second hook-shaped termination and/or an anti-buckling body designed as a separate or separable component, which is arranged detachably or non-detachably in the recess of the second hook-shaped termination.

If the anti-buckling means includes an addition of material at the second hook-shaped end, the device can be manufactured with fewer components. The material allowance can be arranged, for example, on the side facing the recess or on the outside. The material allowance can be arranged, for example, in a bending area of the second hook-shaped termination.

Finally, it proves to be advantageous if the anti-kink body is elastically deformable and/or has a square, rectangular, circular or elliptical cross-section and/or if the anti-kink body includes a rubber band or rubber expander.

In addition, the object is achieved by a profile, in particular a frame profile, for receiving a holding device for flat materials with at least one of the aforementioned features, in which the profile has two base legs that are parallel or inclined to one another to the west, which are connected on a bottom side and form a receiving element for the holding device. The holding device is preferably accommodated in a carrier profile. The fixation with the profile can be improved by locking elements, in particular by round grooves or projections. The latching elements should preferably provide the locking of the holding device in the carrier profile. Thus, the legs of the holding device can have at least one latching element or a plurality of latching elements on the surface, which run essentially parallel to the longitudinal extent of the holding device and are aligned outwards in relation to the receiving volume.

The aforesaid profile has a predetermined longitudinal extension and the profile cross-section, i.e. the cross-section perpendicular to this extension, has two substantially parallel base legs. The latter are connected on a bottom side to form a receiving element serving to receive the holding device. The profile should stabilize the fixture and the profile cross-section can thus be arranged so that the base legs support the legs of the fixture. Thus, in the following, the base leg that is placed on the side of the first (second) hook-shaped termination is also referred to as the first (second) base leg. The profile should not adversely affect the interaction between the fixture and the sheet material. Thus, in particular, the second base leg should be shorter than the first base leg.

It has proven to be advantageous if the base legs of the profile support the legs of the holding device at least in sections, and in particular the base leg which is arranged on the side of the second hook-shaped termination is shorter than the base leg which is arranged on the side of the first hook-shaped termination .

In addition, the height of extension of the first base leg in the profile cross-section corresponds to the height of extension of the leg of the holding device, which provides the first hook-shaped termination. The latter extension height is to be measured in the fixture cross-section, including the first hook-shaped termination.

In such a case, it proves to be expedient if the base leg, which is arranged on the side of the first hook-shaped termination, has essentially the same extension height as the leg of the first hook-shaped termination including the first hook-shaped termination itself of the holding device.

The profile should be made of a more rigid material than the material of the holder, in particular anodised aluminium, steel, rigid plastic or the like, in order to stabilize, support and protect the holder against mechanical damage.

In particular, the aforementioned profile can be a frame profile. Different profiles, like the one described above, are joined together to form a frame. The connection is implemented by known construction methods in the prior art, for example by a miter joint.

The shape of the profile can facilitate the opening of the holding device. For example, the first base leg can have at least one extension between the bottom side and the upper end, which is preferably stepped. The latter facilitates movement of the first hooked termination and provides volume to accommodate the seams of the sheet material.

In such a case, the base leg, which is arranged on the side of the first hook-shaped termination, can have at least one stepped extension between the bottom side and the upper termination.

In addition, the second base leg can have a rounded edge at the upper end, which extends backwards in relation to the receiving volume men is directed to allow movement of the second hooked termination.

It proves to be advantageous if the base leg, which is arranged on the side of the second hook-shaped termination, has a round, inside terminating edge at the upper termination.

In addition, in one embodiment of the profile, it is provided that at least one of the base legs has a receiving device for lighting, in particular LED lighting, on the outside.

The profile can be used either with or without backlighting and it can be used to create light frames, e.g. Thus, the profile can have a recording device and/or a lamp socket for lighting, for example LED lighting, either with or without optical systems. In particular, at least one of the base legs should have the receiving device and/or the lamp socket on the surface which runs parallel to the longitudinal extension of the profile and is directed outwards in relation to the receiving element.

Furthermore, it proves to be advantageous if the profile can be connected at least in sections to a cover strip, which is supported below the bottom side and preferably between the hook-shaped ends of the holding device.

If the aforementioned profile is used e.g. for outdoor use, cover elements can be used to protect the holding device, e.g. against the effects of the weather. In addition, the covering elements also increase the support of the holding device and its locking in the receiving element of the profile. In particular, the profile can be connected to a cover profile, for example to a cover strip, at least in the direction which is perpendicular to the profile cross-section. In particular, the cover profile can be clamped below the bottom side of the profile, e.g. by means of round grooves or projections. Preferably, the covering profile is supported between the two hooked ends of the holding device in order to protect the latter. In addition, this cover profile improves the clamping of the flat material, which lies at least partially between the holding device and the cover profile, since the cover profile preferably applies additional tension to the external and/or internal hook-shaped termination.

If necessary, a profile as described above can form two or more receiving volumes for receiving a holding device. For example, a profile could accommodate two holding devices in order to clamp two flat materials essentially in parallel. Thus, the aforesaid profile can have two receiving volumes, which are arranged opposite to one another with respect to their bottom sides or running obliquely or transversely offset to one another. In addition, in the profile cross-section, the base legs that form the first accommodation volume are oriented in the opposite direction than the base legs that form the second accommodation volume.

The profile can form two mutually opposite receiving elements for the holding device in relation to the bottom side of the profile.

The holding device is accommodated in the profile, in particular in the receiving element of the profile, in order to use a holding device as described below. The aforementioned holding device finds a wide variety of uses in the field of trade fair construction, in the fields of private or commercial interior design, in advertising technology and in the field of art. In particular, the holding device can be used with a corresponding profile for partitions and stretch walls, stretch ceilings, advertising space, or for the production of entrance portals and illuminated frames and for noise reduction. In addition, the aforementioned holding devices can be used anywhere where visual spatial and optical representations are required.

The holding device is arranged in such a way that the flat material to be clamped is pressed between the two hook-shaped ends by means of a round metal spatula, for example. The tensile stress of the sheet material is made possible by the resilience of the holding device material without a welt. If the dimensions of the flat material are larger than the dimensions of the frame profile, the remaining material that cannot be clamped is partially pushed into the receiving volume. The remaining residual material can be cut off above the first base leg. The flat material can thus be removed from the holding device and reused at any time.

Finally, the use of the holding device with one of the aforementioned features as a stretching frame, picture frame, advertising space, illuminated frame, stretching walls, partition walls, stretch ceilings, noise protection walls and/or for the presentation of large pictures proves to be advantageous.

1 shows the cross section of a first embodiment of the holding device 1 according to the present invention. The legs 2, 3 are of substantially the same thickness and are perpendicular to the undersurfaces 32, 33 of their base and parallel to each other. The connection 4 between the legs 2, 3 forms a parabolic arc, the back of the arc 5 is directed inward in relation to the receiving volume 6. The thickness at the base of the arch is greater than the thickness at the tip 7. Thus with the connection 4 a flexible spacing between the legs is provided. In addition, the tip 7 is used as a fulcrum in order to press the legs 3, 4 together and/or spread them apart. The two horizontal dashed lines mark the starting point 8 of the first hooked termination 10 and the starting point 9 of the second hooked termination 11. The bend length 12 of the second hooked termination 11 is greater than the bending length 13 of the first hooked termination 10. In addition, the starting point 9 is outward in relation to the accommodation volume 6 and the second termination 11 bends back on itself. As explained above, this arrangement increases the force directing the tip 14 of the first termination 10 onto the surface 15 of the second termination 11 . As a result, there is also an improvement in the clamping of a flat material. The surface 15 has a structured area 16 . The surface 16 is provided by ribs running substantially perpendicular to the fixture cross-section. The ribs are positioned opposite the tip 14 to improve gripping of a sheet material (not shown). The surface of the leg 2 which is directed outwards in relation to the receiving volume 6 has a projection 17 in the connection area 4 . Likewise, the surface of the leg 3 which is directed outwards in relation to the receiving volume 6 has a projection 18 . The flexible spacing of the legs 2, 3 enables both the insertion of the holding device 1 into the receiving element of the profile and its extraction. The above-mentioned projections 17, 18 enable the holding device to be locked in the receiving element of the profile (not shown). By way of example, the dimensions of the holder device 1 are as follows: width b 1.0 cm, height h approx. 2.8 cm, distance a approx. 0.4 cm. Distance a is the distance between the surfaces of the legs 2 , 3 which are directed backwards in relation to the receiving volume 6 .

2 shows a cross-section of an embodiment of the profile 19 for receiving a holder device (not shown). The first base leg 20 and the second base leg 21 support the legs of the retainer and are perpendicular to the bottom 22 of the profile on which they are connected to form the female element 27. The surface 23 of the bottom 22 is flat and smooth to support the connecting portion 4 of the fixture 1. The surface 24, which is arranged below the bottom 22, has a round fold 25 on. This fold 25 runs essentially perpendicularly to the profile cross-section and is used to lock a cover profile (cf. 5 ). The bottom of the profile provides a cavity 26 which is equidistant from both the top surface 23 and the bottom surface 24 of the bottom 22 . The cavity 26 also has a square cross-section and is perpendicular to the profile cross-section. In the cavity 26, for example, a corner angle can be used to connect the profile 19 with a second corresponding profile 19 or with a plurality of corresponding profiles 19 by a miter joint and thus form a frame, for example. The first base leg 20 provides the stepped extension 28 which, among other things, facilitates the opening of the first closure 10 . The starting point 34 of the extension 28 is equidistant to the two ends 39, 40 of the first base leg 20. The movement of the second end 11 is also limited by the round edge 29 of the upper end of the second base leg 21, which is to the rear in relation to the receiving element 27 is directed, relieved. The surface of the second base leg 21, which is directed outwards in relation to the receiving element 27, has a recess 30, for example for LED lighting. The recess 30 runs perpendicular to the profile cross section and is equidistant to the two ends 41, 42 of the second base leg 21. The surface of the base leg 20, which is directed backwards in relation to the receiving element 27, has a fold 35 in the area of the bottom 22 . Likewise, the surface of the base leg 21 which is directed rearwardly in relation to the receiving element 27 has a fold 36 at the rounded edge 29 . The above-mentioned folds 35, 36 enable the holding device 1 to be locked in the receiving element 27 of the profile. A profile support area 31 is perpendicular to the base legs 20, 21 and is connected to the lower surface 24 of the floor 22 on the side of the second base leg 21. The surface 37 of the profile bearing area 31 and the bottom surface 38 of the cavity 26 are coplanar, ie in the same plane. The profile support area 31 is used to support a rear wall panel in order to increase the stability of the connection through the miter joint and to reflect the light from the LED lighting.

3 shows the perspective view of a further embodiment of the holding device 43. The holding device 1, as in FIG 1 described, is here in the receiving element 27 of the profile 19, described in 2 , recorded. The projections 17, 18 and the corresponding folds 35, 36 are used to lock the holding device 1 in the receiving element 27 of the profile 19 can also vary. The holding device 43 is connected by a joint with a miter cut, for example to a second holding device 43 of similar construction (not shown). The side part 51 of the holding device 43 is also mitred. The corner angle 46 is used for the aforementioned connection and is received in the cavity 26 of the profile 19 and locked by the Allen screws 47, 48. In addition, the corner bracket 46 can be received in the cavity 26 of the profile of the second corresponding holder 43, not shown, and locked in place by further Allen grub screws 49, 50 in order to firmly connect the two profiles together. Based on this, a flat material 44 can then be clamped and fastened between the tip 14 of the first hook-shaped termination 10 and the structured area 16 of the surface 15 of the second hook-shaped termination 11 .

4 shows a cross section of an embodiment of the holding device 43. The holding device 1, as in FIG 1 described, is received in the receiving element 27 of an embodiment of the profile 19 . The embodiment of the profile 19 demonstrates the described features of the embodiment 2 on. In the embodiment after 4 the recess 30 is not equidistant to the ends 41, 42 of the second base leg 21 since the aforementioned recess 30 is at a smaller distance from the end 41. The recess 30 accommodates lighting 45, for example in the form of LED strips. The support 52 of the optical system 53 is received on the surface of the second base leg 21 which is directed outwardly with respect to the receiving element 27 and on the surface of the bottom 22 which is connected to the second base leg 21 . The optical system 53 can be equipped as a lens, for example, and is used to change the direction of the light rays, for example, for light scattering. The corner bracket 46 is received in the cavity 26 of the profile 19 and is joined by a miter joint to a second corresponding holding device 43 (not shown) in order to form, for example, a frame. The profile support area 31 supports a rear wall plate 54 which is preferably riveted or glued to the profile support area 31 . The back panel 54 increases the stability of the connection through the miter joint and reflects the light of the illumination 45. The flat material 44 to be clamped is placed between the tip 14 of the first hook-shaped end 10 and the structured area 16 of the surface 15 of the second hook-shaped end, for example by means of a round metal spatula 57 Conclusion 11 clamped and fastened. The extension of the first base leg 20 provides a volume 55 for stretching the seams 56 of the sheet material 44 to increase the constraint of the sheet material 44 . For example, the dimensions of the holder device 43 are as follows: width d 3.5 cm, height c 4.2 cm, distance e 1.2 cm. Distance e is the distance between the surfaces of the base legs 20, 21 which are directed outwards in relation to the receiving element 27.

5 shows a cross section of an embodiment of the holding device 43. This embodiment has the features of the embodiment of the holding device 43 as in FIG 4 described on. In addition, this holding device 43 has a cover profile 58 in order to protect the holding device 1, for example, against the effects of the weather. Thus, for example, the holding device 43 can be used for outdoor use. The cover profile 58 is detachable and is clamped by means of the fold 25 and a projection 59 on the surface 24 which is arranged below the bottom 22 of the profile 19 . The cover profile 58 is supported in the area 60 between the two hook-shaped terminations 10, 11 of the holding device 1 in order to protect the latter. The leg 61 of the cover profile 58 runs essentially parallel to the base legs 20, 21. In addition, the cover profile 58, the profile 19 and the two hook-shaped ends 10, 11 form a volume 62 for inserting the seams 56 of the flat material 44 and thus a Improving the restraint. The end portion of the sheet material 44 is received between the projection 59 and the fold 25 to provide additional restraint. For example, the dimensions of the holder device 43 are as follows: width d 3.5 cm, height f 4.5 cm, distance e 1.2 cm. The height f is the height of the profile, including the cover profile (58) and distance e is the distance between the surfaces of the base legs 20, 21, which are directed outwards in relation to the receiving element 27.

The cavity 26 of the profile 19 of the holding device 43 can vary. For example, the profile 19 of the holding devices 43, which 6A and in 6B are shown, a cavity 26 whose cross section is rectangular. In particular, the rectangular cross section of the cavity 26 in 6A a base 63 which is longer than the height 64. In contrast, the rectangular cross-section of the cavity 26 in 6B a base 63 which is shorter than the height 64. The shape of the corresponding corner bracket 46, which is received and locked in the cavity 26 of the profile 19, varies accordingly.

7 shows a cross section of a further embodiment of the holding device 43 which has two holding devices 1 . For example, this embodiment can stretch two sheet materials 44 essentially in parallel. The two holding devices 1 demonstrate the described features of the embodiment 1 and are included in profile 19. The profile 19 has two identical receiving elements 27 which share a base 22 . A cavity 26 is placed centrally in the base 22 and the corner bracket 46 is received in the cavity 26 of the profile 19 to connect corresponding brackets 43 together. The two above-mentioned receiving elements 27 are arranged opposite one another with respect to their bottom sides. In addition, the base legs 20, 21 constituting the first receiving member 27 are oriented in the opposite direction than the base legs 20, 21 constituting the second receiving member 27. The base legs 20, 21 are arranged such that this embodiment has an axis reflection through the axis s, which runs parallel to the sheet materials 44 and through the center of the cavity 26. The surface of the bottom 22 which is connected to the two second base leg 21 and the surface of the two second base leg 21 which faces outwards with respect to the receiving element 27 are coplanar. They also form an outer surface 65. The above-mentioned outer surface 65 provides a recess 30 which accommodates lighting 45, for example an LED strip. The support 52 of the optical system 53 is received on the outer surface 65 . The outer surface 65 has two rectangular projections 66 to at least partially support the support 52 of the optical system 53 and to strengthen the profile 19 statically. For example, the dimensions of the holder device 43 are as follows: width d 1.6 cm, height c 7.0 cm, distance e 1.2 cm. Distance e is the distance between the surfaces of the base legs 20, 21 which are directed outwards in relation to the receiving element 27.
