Device for the production of composite profiles for windows, doors or the like.

The innovation relates to a device for producing a composite profile For windows, doors or the like, in which an insulating connecting element Internal and external metal frames running parallel to one another connect the flanges in their C-shaped grooves of the connecting element are inserted, wherein the retaining legs delimiting the grooves by a arranged on the shaft of the device Deformation tool are pressed into recesses in the flanges.

A device of the type mentioned according to DT-PS 2.305.089 is set a relatively complex operation ahead.

It is therefore the task of the innovation to design a device so that it can be operated in a simple manner both manually and mechanically.

The object is achieved according to the invention in that in a plane which is perpendicular to the shaft and spaced from the end of the shaft, a cutting

or "^ rear tool is arranged, its cutting or pushing edges lie on a circle that is adapted to the recesses.

In this way, the shaft of the device can be securely in recesses of the connecting element, while a simple rotary movement is sufficient to confirm the cutting or pressing tool.

The fasteners can be connected to the metal frames in a number of ways be connected, for example by cutting flaps or by embossing beads in the retaining legs.

A device is preferably used for cutting into flaps used, which is characterized, that the cutting edges of the cutting tool lie on a circle which corresponds to the circle for the side surfaces of the recesses.

If the retaining legs are only to be pressed in, then we recommend a device which is characterized in that the pressing edges of the pressing tool lie on a circle that is approximately the Circle corresponds to the respective bending edges of the recesses.

A dovetail-shaped design of the cutting or spinning tool is preferred. In many cases, however, a rotary movement in one direction is sufficient. Then it is advantageous that Train cutting tool Z-shaped.

binding element from both sides, so usually from above and is accessible below, then the devices described are sufficient for fixing. In many cases the metal frames to be connected are however designed so that access is only possible from one level.

In such a case, it is advisable to use the

Device to arrange a further cutting or pressing tool, its distance from the upper cutting or pressing tool of the opening which corresponds to C-shaped grooves. Such a device can be inserted from one side into continuous recesses in the connecting element up to the lower cutting or pressing tool has reached the height of the retaining leg to be processed.

So that the upper cutting or pressing tool can rest securely on the shaft of the connecting element used and continues to do so the shaft does not have to be weakened too much, according to a special embodiment of the invention, the cutting or pressing edges are located of the lower cutting or pressing tool on a circle that is opposite the circle through the cutting or pressing edges of the upper cutting or pressing tool has a smaller radius.

In the case of the H or Z-shaped design of the recesses in the ^{'? T} shank of the connecting element, the lower cutting or pressing tool also preferably H or Z-shaped.

The invention is explained in more detail with the aid of the following exemplary embodiment explained. It shows

Fig. 1 is a vertical section through a composite profile with incisions Lobe according to line I-I (above) and line II-II (below) of Fig. 2,

Fig. 2 is a view from above of the composite profile with the innovation according to the invention Device in rest position (solid line) and in working position (dashed line) and

3 shows, in perspective, a device for producing a composite profile.

The light metal profiles 1, 2 of the composite profile shown in FIG. 1 are connected by insulating connecting elements 3 made of plastic (here is only one connecting element designed as a short piece shown). In detail, the connecting element 3 consists of a shaft 4 and a flange 5 at each end of the shaft. With these flanges 5 are each holding legs 6, which limit the C-shaped grooves 7 of the profiles 1, 2, engaged from behind.

The fastening of the connecting element 3 takes place by deformation the retaining leg 6. To absorb the deformations are in the Flanges 5 recesses 8 triangular cross-section provided.

To a device 9 according to FIG. 3 for the production of a Verbui.dprofils To be able to operate, the shaft 4 of the connecting element 3 has a recess running perpendicular to the shaft plane with cylindrical guide surfaces 11. In the present exemplary embodiment the recess 10 is H-shaped. The recesses 8 are parallel and symmetrical to the central axis 12 of the Recess 10 arranged, the remote from the central axis 12 Side surfaces 13 form tangential surfaces to a cylinder, whose central axis corresponds to the central axis 12.

The device 9 according to FIG. 3 consists essentially of one cylindrical shaft 14, the diameter of which is adapted to the recess 10, and of two arranged in planes perpendicular thereto Cutting tools 15, 16. The upper cutting tool 15 in the plane spaced from the shank end is dovetail-shaped, the lower one Cutting tool 16 is H-shaped at the end of the shank. The distance between the cutting tools 15 * 16 corresponds to the opening h of the C-shaped grooves 7.

The fastening process proceeds as follows: The device 9 is perpendicularly inserted into the recess 10 of the shaft 4 inserted so that the lower part of the shaft 14 is guided by the guide surfaces 11 of the recess 10 and the dovetail-shaped Cutting tool 15 rests on the shaft.

When the device 9 is rotated to the left (see arrows in FIG. 2), for example by means of a hand lever attached to the shaft 14 (or the like), the device 9 is brought from the rest position shown with solid lines into the working position shown with dashed lines. In this case, tabs 17 are cut out of the upper retaining legs 6 by means of the cutting tool 15 and from the lower cold legs 6 by means of the cutting tool 16, since the cutting edges 15 * and 16 'lie on a circle that corresponds to the circle for the side surfaces 13 of the recesses 8 corresponds, and thus a shearing takes place at the opposite edges 18. The tabs 17 lie around the bending edges 19 and are supported with the cut end faces 20 on the side faces 13 of the recesses 8 remote from the central axis 12. During the subsequent, not shown, rotation of the device 9 to the right, the remaining flaps I7 are cut out, so that a secure fastening of the connecting element 3 is achieved by means of a simple rotary movement. The cutting edges 16 ′ lie on a circle with a smaller radius than the cutting edges 15 ¹ . This training is particularly recommended because the connecting element 3 does not have to be paid attention to its position when inserting.

In the present exemplary embodiment, only the cutting of the retaining legs 6 has been described. In a similar way though embossing of beads is also possible if a device
