Ranmen stuck together from square tubes and corner connectors

construction

whoever innovation is based on the task, one made of viscose tubes to create frame construction plugged together and corner connectors, which is heavy-duty and can be used, for example, as a support frame for a shelf.

This object is achieved according to the innovation in that in the The square tubes forming the frame spars are arranged at least one round tube touching the inner walls.

K. In an advantageous embodiment of the innovation, the corner connectors are equipped with projections which engage in the chambers that are formed by the square tube and the Äundrohr in order to prevent rotation between the corner connector and the frame spar.

The two- or three-dimensional frame according to the innovation is inexpensive to manufacture and assemble because the square and round tubes are commercially available and can be connected to one another via a press fit, i.e. without additional fasteners are.

In the subject matter of the innovation, for example, the corner connectors and the square tubes made of plastic geferti _i:;. Are "while e = stand in the Vierkäütruiirc oinsopaStsn üuncLrcüro metal * This results in a corrosion-resistant frame structure which is light in weight, but a high load owns.

Embodiments of the innovation are shown in the drawing and are described below. Show it:

in perspective view; the frame spar is partially cut,

2 shows a further embodiment of a corner connector and an associated frame spar in perspective

JTOXd UCXXUlIg,

3 shows a modification of the corner connector according to FIG.

In the embodiment according to FIG. 1, the frame spar 1 consists of a plastic square tube 2 in which a round tube 3 made of metal is arranged. The tube 3 can also be made of plastic. The round pipe 3 contacts the inner walls of the four (square tube 2 and is frictionally connected with the square tube, the intermediate round pipe 3 and the "square tube 2, a press fit, the gewährleifoet a unique fixing of the circular tube.

In the exemplary embodiment, the round tube 3 ends at a certain distance from the end face 4 of the square tube 2. This creates a receptacle 5 for the square block 6 of a corner connector 7, through which a twist-proof connection between the corner connector 7 and a frame spar 1 is achieved.

The square block 6 is in one piece with a cylindrical arm 8, the outer diameter of which corresponds to the inner diameter of the Round tube 3 corresponds. The boom 8 thus dips into the round tube when the rear spar 1 is plugged onto the corner connector 7 a.

In the embodiment according to FIG. 2, the round tube 9 extends over the entire length of the square tube 10. The Eukver-uinder 11 has cylindrical arms 12 _; the outer diameter of which corresponds to the inner diameter of the round tube 9, so that these arms dip into the interior of the tube 9 when the corner connector and the frame spar are connected.

To achieve a torsion-proof connection between the frame spar and the corner connector, the corner connector is equipped with protrusions 13 which are shown in front of % * at a distance of the wall thickness of the round tube 9 from the cylindrical arm 12. When attaching the frame spar 1, the "V orrr stanchion 13" engages in the chambers 14, 15, 16 and 17, which are started by the square tube and the round tube 9.

These protrusions 13, which are in the Pig. 2 of the (cross-section contour of Chambers 14 to 17 are adapted, can also by cylindrical Projections 18 are formed.

While corner connectors for two-dimensional frame structures are shown in FIGS. 1 and 2, the.; corner connector according to the I ¹ Ig. 3 used for a three-dimensional frame construction.

Instead of a round tube that extends over the entire length or Extending almost the entire length of the frame spar, you can also use round tube sections that are inside the square tube be arranged with a certain distance.
