Definitions

  • the invention relates to a connecting element for the non-positive connection of supporting elements of a supporting structure with partial elements arranged on the delimitation planes of a body.
  • connecting elements are known. These are used, for example, to connect profiles called support elements to one another in such a way that a frame structure is created.
  • This frame structure forms a supporting structure into which wall or shelf elements can be inserted, for example to produce a trade fair stand. Since the structures composed of the profiles can be relatively extensive, the connecting elements used at the nodes are of particular importance.
  • the known connecting elements are constructed in a relatively complicated manner in order to apply a sufficiently large load-bearing capacity and are therefore only expensive to produce.
  • the invention has for its object to provide a Ver ⁇ connecting element of the generic type, that simply constructed and inexpensive to manufacture
  • this object is achieved by a connecting element with the features mentioned in claim 1. Due to the fact that the adjoining partial elements have an essentially linear contact and are positively connected to one another via holding elements preferably arranged at right angles to the partial elements, it is advantageously possible to produce the connecting element from simple partial elements which are not complicated Connection technology among themselves. Since the sub-elements only touch one another linearly and preferably only point-wise, complex connection, for example by welding along a contact surface between the individual sub-elements, is not necessary. Due to the holding elements arranged at right angles to the partial elements, via which the partial elements are non-positively connected to one another, they can be arranged with great rigidity to one another. Since the holding elements are arranged essentially perpendicular to the partial elements, the partial elements are easily supported in such a way that connecting elements assembled from the partial elements can absorb a large load-bearing capacity.
  • the sub-elements are flat elements arranged on the delimitation planes of a throwing egg, which are preferably designed as circular elements and touch each other point-like on their peripheral edges.
  • the holding elements are formed by angle elements which engage with their legs in receptacles preferably provided on the partial elements.
  • the entire connecting element can be plugged together in a modular manner by means of the holding elements and the sub-elements and nevertheless absorb large load capacities. Due to this modular plug-in of the individual parts of the connecting element, any body can be realized as connecting elements.
  • the preferably formed reforms can Sub-elements are arranged like a prism when using three sub-elements and polygon-like when using a correspondingly large number of sub-elements.
  • the sub-elements have at least one passage opening through which a fastening element for support elements which can be attached to the outer sides of the sub-elements can pass.
  • support elements can be locked in a simple manner, for example by means of threaded screws, on the part elements of the connecting element.
  • connection options are also possible, for example by means of bayonet locks, by means of snap locks, etc.

  • FIG. 1 shows a connecting element, generally designated 10.
  • the connecting element 10 has a total of six sub-elements 12, which are each arranged on the boundary surfaces of a cube-shaped spatial body.
  • the Railele ⁇ elements 12 are designed as flat surface elements 14, which have a circular plan.
  • the sub-elements 12 are referred to below as circular elements 16.
  • the design as circular elements 16 is only an example, so the partial elements 12 can also have an oval, polygonal or other cross-section.
  • the circular elements 16 of the connecting element 10 only touch one another point-wise on their peripheral edges 18. Two adjacent circle elements 16 are arranged at right angles to one another, with a point-like contact on the peripheral edges 18. According to a further embodiment, not shown, the connecting element 10 can also have more than six sub-elements 12, so that these are not arranged at a right angle to one another. The angles between two partial elements 12 touching each other are then, for example, more than 90 °.
  • the circular elements 16 are connected to one another by means of holding elements 22, the holding elements 22 being arranged such that they connect two adjacent circular elements 16 to one another in a force-locking manner.
  • the holding elements 22 are designed as angle elements 24 running at right angles to the circular elements 16.
  • the angle elements 24 each engage with a leg 26 in recesses 28 of the circular elements 16.
  • the recesses 28 are formed by slots 30 which are open at the edge and run on a radial of the circular elements 16.
  • the circular elements 16 are thus joined with the holding elements 22, the overall structure shown in FIG. 1 being created.
  • the connecting element 10 according to the invention shown in the example consists of a total of six circular elements 16 and twelve holding elements 22. After the joining of the circular elements 16 with the holding elements 22, the connecting points can additionally be welded, for example under vacuum.
  • the overall result is a compact connecting element 10 which is capable of absorbing large load capacities. Due to the holding elements 22 running at right angles to the circular elements 16, a load bearing on the circular elements 16 can be very well absorbed and derived from the immediately adjacent circular elements 16.
  • the circular elements 16 have a through opening 32 which is preferably located in the center.
  • the through opening 32 is selected such that a fastening element for the support elements can pass through them.
  • This can be, for example, a fastening screw, the threaded shaft of which extends from the inside through the through opening 32 and can be screwed tightly into a threaded bushing of a support element (not shown).

  • the free spaces 34 remaining in the corner points of the imaginary throwing egg can be used to introduce the connecting screw.
  • the free spaces 34 result from the circular design of the circular elements 16.
  • a screwdriver can be passed through the through opening 32 of the circular element 16 arranged opposite, by means of which the connecting screw can be tightened.
  • the circular elements 16 also have relatively large-area openings 36 which are arranged between the through opening 32 and the slots 30. These breakthroughs 36 result in a considerable saving in weight for the connection 10, compared to solid circular elements 16.
  • the openings 36 are further suitable for laying lines for various media, for example electricity, telephone, data (computer network), air, etc., through the connecting element 10.
  • All circular elements 16 of the connecting element 10 are symmetrical and identical, so that each circular element 16 can be used on any side surface of the connecting element 10. Because of their simple and symmetrical shape, the circular elements 16 can be mass-produced, for example as stamped parts. Overall, a very inexpensive manufacture of the connecting elements 10 is thus possible.

  • the holding elements 22 are arranged on three levels E1, E2 and E3.
  • the planes E1 and E2 run perpendicular to the sheet plane, as shown in FIG. 2, while the plane E3 runs horizontally to the sheet plane.
  • the levels E1, E2 and E3 run at right angles to one another, and the intersection of the levels E1, E2 and E3 lies in the center of the connecting element 10.
  • the holding elements have a cutout 40 such that the circular elements 16 which are in contact do not receive any additional positive locking.
  • the cutouts 40 lead to engagement grooves 41 (FIG. 1), into which corresponding projections of support elements which can be fastened to the connecting element 10 can engage. As a result, torques acting on the support elements can be well absorbed by the connecting element 10.
  • the circular elements 16 have a radius r which is selected such that when circular element 16 and holding element 22 are projected in one plane, a hypotenuse 38 of the holding element 22 does not intersect the peripheral edge 18 of the circular elements 16. It thus follows that the free spaces 34 formed by three directly abutting circular segments 16 are not delimited by excessively large holding elements 22.
