__ ^ IMXJNGSE___MENT

The invention relates to a connecting element for the frictional connection of supporting elements of a supporting structure according to the preamble of claim 1.

Connecting elements of the type mentioned here are used in particular to create supporting structures or lattice structures which are formed from a plurality of supporting elements or struts which are fastened to the connecting elements. Wall or shelf elements can be inserted between the struts in order to ultimately implement a trade fair stand, for example.

Connecting elements of the type mentioned here are known. They are also known as connecting cubes or nodes. It has been found that the load-bearing capacity of the connecting elements is often not sufficient for large structures.

It is therefore an object of the invention to create a connection element of the type mentioned above.

fen, which is characterized by a particularly high load capacity.

This object is achieved in a connecting element according to the preamble of claim 1 with the aid of the features mentioned in this claim. Because the connecting element is composed of rigidly connected sub-elements which are arranged in three mutually perpendicular planes, the forces introduced into the connecting element are absorbed particularly well, so that there is a very high rigidity of the connecting element and thus a results in high load capacity.

An embodiment of the connecting element is particularly preferred, in which the intersection lines of two planes each lie inside the connecting element, that is to say are arranged inside an envelope enclosing the connecting element. Such an arrangement leads to a particularly high stability of the connecting element.

In a further preferred exemplary embodiment of the connecting element, the partial elements arranged in one plane, preferably all partial elements, are of identical design. This leads to a particularly inexpensive implementation of the connecting element.

Furthermore, an embodiment of the connecting element is preferred in which the partial elements are essentially triangular and preferably sy are of metric design, the cathets of the sub-elements lying in imaginary outer surfaces of the connecting element. This creates a free interior of the connecting element, into which it is possible to intervene by means of suitable tools, so that supporting elements of a supporting structure can be attached to the connecting element.

An embodiment of the connecting element is particularly preferred, in which the partial elements are coupled to one another via composite pieces which are arranged in a plane on which the levels are vertical, in which the partial elements attached to the composite piece are arranged. This also results in a particularly high stability of the connecting element.

Further configurations of the connecting element result from the remaining subclaims.

The invention is explained in more detail below with reference to a drawing. Show it:

Figure 1 is a plan view of four sub-elements of the connecting element arranged in one plane;

FIG. 2 shows a side view of the complete connecting element;

FIG. 3 shows a section through a first exemplary embodiment of a fastening element which can be attached to the connecting element; Figure 4 shows the fastener according to Figure 3 in plan view

Figure 5 shows another embodiment of a fastener.

In FIG. 1, four triangular-shaped partial elements 1, preferably of identical design, are shown, which are arranged in a first plane E1 and are rigidly connected to one another via composite pieces 3. The composite pieces 3 are, for their part, preferably identical and designed as ring elements, the thickness of which is greater than that of the partial elements. The composite pieces 3 are preferably twice as thick as the partial elements 1. The composite pieces 3 are provided on their peripheral surface with slots into which the partial elements 1 are inserted and fastened in a suitable manner. If the part elements 1 and the composite pieces 3 are made of metal, a connection by brazing or welding can be selected. The slots 5 selected in the composite pieces 3 result in a particularly rigid connection between the partial elements 1 and the composite pieces 3 and thus a high stability or load-bearing capacity.

While the part elements 1, which are in themselves flat, are all arranged in the plane E 1, the composite pieces 3 are oriented perpendicular to the part elements; they are thus perpendicular to the image plane resulting in FIG. 1. The sub-elements 1 are symmetrical, namely as isosceles right-angled triangles. In the vicinity of the intersection points 9 formed by the cathets 7 of the sub-elements 1, projections 11 originating from the cathets 7 are provided, which also lie in the plane E1. The distance of the projections 11 from the intersection points 9 corresponds approximately to the material thickness or thickness of the sub-elements 1. When producing a supporting structure, the projections 11 engage in the supporting elements which are attached to the connecting element. In the arrangement of the projections 11 selected here, the forces introduced into the projections are optimally introduced into the composite pieces 3, so that the above-mentioned high stability or load-bearing capacity results.

Openings 13 are provided near the vertices 9, which are used to attach fastening elements for producing a wind bandage.

The partial elements 1 rigidly connected to one another in FIG. 1 form a first assembly B1 of the finished connecting element.

Sub-elements which are perpendicular to the image plane of FIG. 1 are again inserted into the slots 5 of the composite pieces 3 shown in FIG. Two opposite sub-elements then lie in a plane E2 or E3. The partial elements that are perpendicular to the image plane of FIG. 1 are in turn connected by a composite piece 3, as can be seen in FIG. 2 is. This illustration shows the connecting element 10 in side view, the four partial elements 1 shown in FIG. 1 lying in the plane E1 and the four perpendicular partial elements 1 which are connected to one another via the connecting piece 3.

The sub-elements shown in FIG. 1 thus form the first assembly B1, while the sub-elements arranged vertically on them result in an assembly B2 lying in plane E2 and an assembly B3 lying in plane E3, the assemblies B2 and B3 being perpendicular to one another place and at the same time perpendicular to the assembly Bl.

It can be seen that the imaginary intersection lines El two and E2, El and E3 or E2 and E3 lie in the interior of the peripheral surface of the connecting element and preferably intersect at the imaginary center of the connecting element 10. The forces absorbed by the assemblies B1, B2, B3 are thereby optimally absorbed, so that they result in high stability or load-bearing capacity. In addition, the connecting element 10 is characterized by a high torsional rigidity.

In FIG. 2, in addition to the assembly B1 consisting of four sub-elements 1 shown in FIG. 1, the two further assemblies B2 and B3, which are perpendicular to the image plane according to FIG. 1, are shown. The sub-elements 1 of the two assembly pen B2 and B3 are rigidly and non-positively connected to one another in the manner described by a composite piece 3, the partial elements 1 engaging in the slots 5 which are introduced into the peripheral surface of the composite piece. In the illustration according to FIG. 2 it is clear that the connecting pieces 3 are ring-shaped and have a central through hole 15 through which, for example, a fastening screw can be passed in order to attach a support element to the connecting element 10.

All assemblies B1 to B3 are virtually identical, so that the manufacturing costs for the connecting element 10 are particularly low.

In the exemplary embodiment shown here, the sub-elements 1 lie within an imaginary square. However, it is also possible to design the partial elements in such a way that they are arranged within an imaginary rectangle. The sub-elements 1 are each aligned so that their cathets 7 lie in the imaginary outer surface of the connecting element 10 and the corners formed by the cathets and hypotenuse are attached to the composite pieces 3.

The composite pieces 3 are in turn all identical and are preferably made of metal. It is also conceivable to use stamped parts here.

FIG. 2 shows that the composite piece 3, which is shown in plan view, is shown in one plane. is arranged, which is perpendicular to the levels E2 and E3 of the assemblies B2 and B3. The addressed composite piece is thus arranged parallel to the plane E1 in which the sub-elements 1 of the assembly B1 are arranged. Accordingly, the other composite pieces are arranged parallel to the levels of the other assemblies.

It can be seen that each four sub-elements 1, which are arranged in a plane E1, E2 or E3, are all connected to one another in the same way, as can be seen from FIG.

If the connecting element 10 is disassembled, the arrangement of the sub-elements 1 shown in FIG. 1 results for the view of the individual assemblies B1, B2 and B3. The side view of the connecting element 10, which is shown in FIG. 2, results for all six sides of the essentially cube-shaped connecting element 10.

It is clear from FIGS. 1 and 2 that the hypotenuses 17 of the sub-elements 1 run essentially parallel to an imaginary diagonal that connects two opposite intersection points 9 with one another. This creates a space in the interior of the rigidly interconnected sub-elements 1, through which one can freely intervene in the interior of the connecting element 10, for example screws which are passed through the through holes 15 of the composite pieces 3 and in supporting elements of a supporting structure intervene to fix. Despite the large free space inside the Connecting element 10 results in a very stable, rigid connection not only between the individual sub-elements 1 but also between the composite pieces 3, so that the connecting element 10 has a very high stability or load-bearing capacity.

Fastening elements can be attached to the openings 13 in the sub-elements 1, which are used to anchor a wind bandage on the connecting element. Such fasteners are briefly explained with reference to Figures 3 to 5:

FIG. 3 shows a cross section through a first exemplary embodiment of a fastening element 20 which has an essentially circular base body 21 which is provided with a through hole 23. The base body 21 has a projection 25, into which a blind hole 27, which runs perpendicular to the through hole 23 and has an internal thread 29, is introduced. A screw can be passed through the through hole 23 and penetrates the opening 13. A threaded rod can be screwed into the internal thread 29 or any anchoring for the wind bandage.

In order to ensure a particularly uniform introduction of the forces into the connecting element 10, two mutually opposite fastening elements 20 can also be provided, which are attached on opposite sides of the partial element 1. The shape of the fastening element 20 according to FIG. 3 results particularly clearly from the top view in FIG. 4, from which the essentially circular base body 21 of the fastening element 20 and the projection 25 provided with the blind hole 27 shown in broken lines can be seen. The through hole 23 is also clearly visible.

FIG. 5 shows a top view of a further exemplary embodiment of a fastening element 20, the base body 21 of which is in turn provided with a through hole 23. The basic body 21 is again essentially circular, but here - in contrast to the exemplary embodiment according to FIG. 4-, the through hole 23 is arranged eccentrically with respect to the imaginary center of the basic body 21. A blind hole 27 with an internal thread 29 extends perpendicular to the through hole 23, as in the exemplary embodiment according to FIG. 4-, into which a threaded rod 31 engages in order to produce a wind bandage.

The blind hole 27 is preferably made in the larger area of the base body 21, which is released through the offset through hole 23 and thus has increased stability.

Also in the exemplary embodiment of the fastening element 20 shown in FIG. 5, it can be assumed that when the force is introduced into the connecting element 10 as symmetrically as possible, two fastening elements arranged on opposite sides of a partial element 1 are provided. will be seen, which are anchored to the sub-element 1 by means of a screw which extends through the through holes 23 and through the opening 13.

Because the openings 13 are preferably arranged on the imaginary diagonal, which connects two mutually opposite intersection points 9 to one another, the forces are introduced by the fastening elements 20 into the partial elements 1 such that two adjacent composite pieces 3 are loaded practically uniformly are and the forces are evenly introduced into the connecting element 10. This also results in a particularly high stability or load-bearing capacity of the connecting element 10, because two connecting points between a partial element 1 and the adjacent connecting pieces 3 are evenly loaded with the forces generated by the wind bandage.

The fact that the projections 11 of the sub-elements 1 engage in the supporting elements or struts which are attached to the connecting element 10 results in a secure, stable form-fit which also ensures the absorption of high torsional forces. The torsion forces are safely absorbed by the stable and rigid construction of the connecting element 10.

The connecting element 10 as a whole is symmetrical in itself, so that all of the six sides of the Connecting element 10 acting forces are equally well absorbed and intercepted.
