Profile for fastening at least one preferably rod or beam-shaped

and/or flat component

The invention relates to a profile for fastening at least one preferably rod- or beam-shaped and/or flat structural element, in particular a wall element, according to the preamble of claim 1.

Profiles of this type are used, for example, in shop, trade fair and exhibition construction to build display and presentation walls, exhibition stands and the like. The profiles are usually used as stands, which are then connected, for example, via corresponding components in the form of longitudinal and transverse beams or wall elements to form a flat or spatial structure.

Profiles are known from the state of the art that have groove-like fastening rails for connecting the components. The groove-like fastening rails are part of the profile and run over the entire axial length of the profile. The profiles are usually made of plastic or light metal and are produced by extrusion or a similar process.

Forming processes are used. Usually, several fastening rails are arranged rotationally symmetrically around the longitudinal axis of the profile, so that several wall elements or the like can be arranged and connected at an angle or in alignment with one another. For fastening, the known wall elements have fastening elements, for example in the form of so-called turnbuckles, as are known for example from DE 42 19 717 A1, with which the wall elements are tensioned with their front or side surface against the flange surfaces on both sides of the slot-like opening of the fastening rails. A disadvantage of such a design, however, is that the moments that occur when the wall elements are loaded laterally with respect to the longitudinal axis of the profiles are absorbed almost exclusively by the fastening elements, which means that if the load or handling is improper, the fastening elements can tear out of the groove of the fastening rail and the connection can come loose, causing damage to the profile.

Based on this prior art, the object of the present invention is to create a profile which does not have these disadvantages and in particular enables improved moment absorption when the components are subjected to lateral loading.

This problem is solved by a profile according to the teaching of claim 1.

Advantageous embodiments of the invention are the subject of the subclaims.

The profile initially has a profile base body with at least one fastening rail running in this profile base body in the longitudinal direction of the profile, into which a fastening element for fastening the component can be brought into releasable engagement.

According to the invention, at least one support leg is provided which is arranged on the profile base body or can be fastened to it and against which the component can be brought to rest directly or indirectly for laterally supporting purposes. Due to this design, a lateral load and thus the moments which occur are no longer absorbed only by the connection of the fastening element in the fastening rail, but by the force-transmitting contact of the component with the support leg.

If only loads are expected from one side, the arrangement of a support leg on one side of the fastening rail may be sufficient. According to a preferred embodiment of the invention, however, at least two support legs are arranged in pairs on both sides of the fastening rail, opposite each other. With this design, support can be provided on both sides and thus a moment can be absorbed in both loading directions. The two support legs preferably form an opening between them, the width of which essentially corresponds to the thickness of the structural element to be supported, for example a wall element. This allows the structural element to be easily inserted into the gap between the support legs.

In principle, a profile according to the invention can also have just one fastening rail, for example if the profile serves as the end profile of a stud wall configuration. According to a preferred embodiment, however, at least two, but preferably four or eight fastening rails are provided in or on the profile base body, which are arranged axially or rotationally symmetrically to the profile's longitudinal axis. This allows several components to be connected at an angle or in alignment with one another to form, for example, a spatial wall structure or the like.

Preferably, the support legs are arranged in one piece on the profile base body, in particular molded onto it. For example, the

Profile can be manufactured as a one-piece extruded profile. The profile can be made of plastic or metal, in particular a light metal alloy, and not only in this embodiment.

According to a further embodiment, the adjacent support legs of adjacent fastening rails are connected to one another in a web-like manner at least in sections. This makes it easy to achieve an outer contour of the profile according to the invention that is closed in the circumferential direction, whereby the slot-like openings between the support legs of each fastening rail initially remain open to accommodate the components.

Preferably, the space between the opposing support legs of a fastening rail is designed to accommodate a closing and/or fastening element. In other words, instead of the components, if required, closing elements can be attached to the profile to cover the slot-like opening between the support legs when no component is to be arranged and fastened. A fastening element, for example in the form of a fastening rail with slot-like openings, can be used when shelf supports or the like are to be detachably attached to the fastening element by hooking them into the slot-like openings in a known manner and thus detachably arranged on the profile.

According to a further embodiment, the areas of the support legs facing each other are each provided, at least in sections, with at least one groove-like recess running parallel to the longitudinal axis of the profile, into which a locking element of the closure and/or fastening element that is complementary in terms of shape and/or function can be brought into releasable engagement. This makes it easy to achieve a releasable fastening that can be achieved either by inserting the closure or fastening element into the Razm

between the opposite support legs or by elastic locking from the slot-like opening.

The end and/or fastening element can be designed in a simple manner as a rail with a substantially U-shaped cross section and the locking elements can be arranged on the outer surfaces of the legs of the U-profile.

Preferably, stop elements are provided in the space between the opposing support legs of a fastening rail, against which the outer and/or inner surfaces of the legs and the outer or inner surface of the base flange of the U-profile can be brought into contact in such a way that the end and/or fastening element is mounted essentially free of play. This is particularly advantageous if fastening elements are to be used to fasten shelf supports or the like, for example, since this enables a play-free, supporting transfer of the load to be carried as intended to the profile.

According to a particularly preferred embodiment of the invention, the support legs are designed as separate support elements that can be fastened to the profile base body, in particular can be detachably fastened. This makes it particularly easy to equip or retrofit existing profiles with support legs according to the state of the art.

Preferably, two support legs are connected to one another in the region of their first end by a web-like connecting region and have a hook-like rear grip in the region of their second end, which can be releasably engaged in a fastening rail of the profile base body. This makes it possible to achieve an essentially closed outer circumference of the profile between the fastened components in a simple and particularly aesthetically pleasing manner, while at the same time providing high torque absorption.

In the following, the invention is explained in more detail with reference to drawings showing only preferred embodiments. It shows

and

Fig. 5 shows a further embodiment of a profile of the invention for the fastening of up to eight components in a representation corresponding to Figs. 1 to 4.

The profile 1 shown in Fig. 1 has a profile base body 2, which essentially consists of a central tube 3 and two groove-like fastening rails 4 and 5 formed integrally on the central tube 3. In addition to stabilizing the profile base body, the central tube can be used, for example, to accommodate feet, connecting parts and the like, as well as to lead through electrical connection cables in particular. The fastening rails 4 and 5 each have two side webs 6 and 7 and a front web 8, in

in which a continuous slot 9 is formed running over the entire length of the fastening rails 4, 5.

Furthermore, two pairs of support legs 10 and 11 are arranged on the profile base body 2. The support legs 10 and 11 are formed with their first ends 12 and 13 in the area in which the central tube 3 and the side webs 6 and 7 of the fastening rails 4 and 5 are connected to one another, in one piece with the profile base body 2. With their second and free ends 14 and 15, the two support legs form a slot-like opening 16 between them, which extends over the entire axial length of the profile 1.

A structural element 17 in the form of a flat wall element, which is only indicated schematically, reaches with its front side through the opening 16 into the space between the two support legs 10 and 11 and comes to rest with its front surface 18 on the front web 8 of the fastening rail 5. A known fastening element 19 in the form of a turnbuckle, which is only indicated schematically, is arranged in the structural element 17. The fastening element 19 has a locking bolt which protrudes from the front side of the structural element 17 and engages through the slot 9 in the fastening rail 5. By actuating it with a tool (not shown), the locking bolt of the fastening element 19 can be brought from a position in which it can be inserted and removed through the slot 9 of the fastening rail 5 into the locking position shown in Fig. 1, in which the front surface 18 is forced onto the front web 8 and the structural element 17 is thus fixed to the profile 1.

The component 17 has a thickness d which essentially corresponds to the distance between the free ends 14 and 15 of the support legs 10 and 11 and thus to the width of the slot 16. "Essentially" means that the component 17 can be inserted into the slot 16 with little play, but possibly also under slight prestress. Due to this practically positive reception of the component 17 between

Front web 8 and the support legs 10 and 11 result in a supporting system of the structural element 17 on the support legs 10 and 11, so that in particular a considerable improvement in the moment absorption between the structural element 17 and profile 1 and thus a considerably improved stability, for example of a stud wall or the like constructed with profiles 1 according to the invention, can be achieved.

Between the support legs 10 and 11, a slotted recess 20 and 21 (see Fig. 2) is formed in the profile 1. These recesses can be used in a manner known per se to attach additional elements such as shelving elements, lighting elements or the like to the profile 1.

As can also be seen from Fig. 2, two spaces 22 and 23 are formed in the profile 1 between the opposing support legs 10 and the fastening rails 4 and 5. If these are not used for the connection or fastening of components 17 when the profile 1 is used as intended, end elements 24 or fastening elements 25 can be brought into these spaces 22 and 23 and fixed there.

The end element 24, which essentially serves as a cladding, has a substantially U-shaped cross-section, with the base flange 26 being adapted to the external geometry of the profile 1, curved in the embodiment according to Fig. 2. This results in an aesthetically pleasing design of the overall profile. The two legs 27 and 28 of the end element 24 each have locking elements 29, 30 in the form of rail-like noses on their outer surfaces, which extend essentially over the entire axial length of the end element 24. In the area of the free ends 14 and 15 (cf.

Fig. 1) of the support legs 10 and 11, these are provided with groove-like recesses 31 and 32 on the inner surfaces facing each other.

which are designed and arranged to be complementary in shape and function to the locking elements 29 and 30. In other words, this means that the end element 24, when installed as intended, engages with the locking elements 29 and 30 in the recesses 31 and 32 and is thus held securely. The end element 24 can be inserted by pushing the end element 24 into the profile from the front side. In particular, if the end element is made of an elastic and easily deformable material, for example plastic, a snap-in connection in the manner of a clip is also conceivable, the end element then being inserted from the opening 16 by elastically deforming the legs 27 and 28 and snapping the locking elements 29 and 30 into the recesses 31 and 32.

Furthermore, in the embodiment according to Fig. 2, a fastening element 25 is provided, which is used, for example, for fastening shelves, trays or the like. The fastening element is designed as a rail with a U-shaped cross section, which is provided with slots (not shown) at regular intervals in the area of its base flange 33 for receiving, for example, shelf supports. On the outer surfaces of the side webs 6 and 7 of the fastening rails 4 and 5, web-like stop elements 34 and 35 in the form of stop strips are provided, against which the front sides of the legs 36 and 37 of the fastening element 25 come to rest in a supported manner. At the same time, the inner surfaces of the legs 36 and 37 come to rest in some areas on the outer surfaces of the side webs 6 and 7. In the area of the transition from the legs 36 and 37 to the base flange 33, the fastening element 25 is supported against bearing surfaces 38 and 39 (see Fig. 1) that complement each other in terms of shape and function. This results in the fastening element 25 being supported and fixed in the space 23 of the profile 1 with virtually no play, so that the loads intended to be absorbed by the fastening element 25 can be transferred reliably and safely to the profile 1.

While the profile according to Figs. 1 and 2 can only be used to create straight-line structures of components or to use them primarily as end elements of complex geometries produced with profiles according to the invention, angular structures can be achieved with the embodiment shown in Fig. 3. The profile 40 has a profile base body 41 which essentially consists of a central tube 42 and four fastening rails 43 arranged rotationally symmetrically around the central tube 42 and formed integrally thereon.

Furthermore, four pairs of support legs 44 and 45 are arranged on the profile base body, which are integrally formed with their first ends on the fastening rails 43 and each form a slot-like opening 48 with their second free ends 46 and 47, which extends over the entire axial length of the profile 40 and which in turn essentially corresponds to the thickness of the component to be fastened. In this respect, the basic structure of this embodiment corresponds to the embodiment according to Figs. 1 and 2.

The components 49 and 50, which are offset at right angles to one another, each engage through the slot-like opening 48 into a space 52 formed between the support legs 44 and 45 and the front web 51 of the fastening rail 43 and come to rest with their front surface on the front web 51 as well as with their side surfaces on the free ends 46 and 47 of the support legs 44 and 45. The outer surface of the components 49 and 50 is provided with a paneling 53 so that the supporting contact with the support legs 44 and 45 takes place indirectly. At the same time as the support at the free ends 46 and 47 of the support legs 44 and 45, in this embodiment the structural elements 49 and 50 are supported laterally on both sides on the support legs 44 and 45, also in the area immediately above the front web 51 on the side surfaces 55 and 56, whereby the moment absorption or moment support is considerably improved.

The adjacent support legs 44 and 45 of two adjacent fastening rails 43 are connected via connecting sections 54 which are web-like in cross section and extend over the entire axial length of the profile 40, so that overall, apart from the openings 48, an overall profile which is closed in the circumferential direction is obtained.

As in the embodiment according to Fig. 1 and 2, the embodiment also includes a closing element 57 extending over the entire axial length of the profile 40. To secure the closing element 57, it has two side flanges 58 and 59, the ends of which can be releasably engaged in recesses 60 and 61 formed in the support legs 44 and 45. Assembly is carried out as described above by inserting it into the profile 40 from the front side.

The embodiment shown in Fig. 4 corresponds largely to the embodiment according to Fig. 3. In contrast to this, however, the distance a between the side surfaces 55 and 56 of the support legs 44 and 45 is at least slightly larger than the width d of the slot-like opening 48 and thus also the thickness of the component 17 to be fastened. This means in particular that the lateral support of the component 17 and thus the moment absorption again takes place exclusively via the free ends 46 and 47 of the support legs 44 and 45.

A fastening element 25 can be introduced into the space 52 between the two support legs 44 and 45, which has exactly the same structure, the same shape and the same function as the fastening element according to Fig. 2. The fastening element comes to rest with the outer surfaces of its legs 36 and 37 on the side surfaces 55 and 56 of the support legs 44 and 45, with the end faces of its legs 36 and 37 on the front web 51 of the fastening rail 43 and with the transition area between the legs 36 and 37 and the base flange 33 on the free ends 46 and 47 of the support legs 44 and 45.

This ensures a secure and resilient fixation of the fastening element 25.

Fig. 5 shows a further embodiment of a profile according to the invention. The profile 62 has a profile base body 63, which in turn consists essentially of a central tube 64 and fastening rails 65, which are integrally formed on the central tube 64. In this embodiment, a total of eight fastening rails 65 are arranged rotationally symmetrically on the central tube 64. This results in a profile base body 63 with an octagonal cross section and also eight outer surfaces, which are formed by the front webs 66 of the fastening rails 65 and are slotted over their full length as described above.

The fastening of a component 17 takes place in the manner described above by engagement of an actuatable fastening element 19 arranged on the component in the form of a turnbuckle with locking bolt, which engages through the slot-like opening in the fastening rail 65, engages behind the front web 66 and thus forces the front surface of the component 17 onto the front web 66 when the turnbuckle is tightened.

Two support elements 67 and 68 are detachably attached to the profile base body 63. Each support element 67 and 68 has two support legs 69 and 70 or 71 and 72, which are each connected to one another by a web-like connecting area 73 or 74. The support legs 69 and 70 or 71 and 72 are each provided with a hook-like rear grip 75 at their free end, which engages through the slot-like recess in the fastening rail 65 and engages behind the front web 66. The hook-like rear grips 75 of a support element can engage in the same fastening rail 65 or, as shown in Fig. , in spaced-apart fastening rails. Due to the opposing orientation of the hook-like rear grips 75 of each support element 67, 68, the support elements are securely fixed.

elements on the profile base body 63 so that a reliable moment recording of the components 17 can take place.
