Door fitting.

The innovation relates to a door fitting, in particular in the form of a shield, a rosette or the like, with a bearing bush, preferably made of abrasion-resistant plastic, assigned to the shield, for the shaft of the handle or the like, which is located in a support part protruding over the rear bearing edge of the shield, preferably in the form of a collar _; continues.

In the known designs of such door fittings, in which the support part and bearing bushing are preferred are uniformly formed from plastic, the fixed association between this plastic part and the shield is inadequate. She is in essentially only achieved in that on the one hand this, the bearing bush and the support part comprehensive plastic component largely form-fitting between the rearward-facing edges of the

702083410.12.70

Shield is and on the other hand, the bearing bush protrudes with an annular bead over the front of the shield. Even additional, inwardly directed retaining lugs extending from the inner wall of the shield edge cannot bring about a sufficiently fixed assignment of this plastic part to the shield.

The task of the present innovation is to create a door fitting of the generic type which, in a simple design, has a stable assignment between Legerbüchse that can withstand all stresses and shield is reached.

This is achieved according to the innovation in that

from the edge of the handle opening of the

Shield protruding backwards, with undercut Anchors equipped with holding surfaces for holding

the bearing bush run out.

An advantageous design here is, according to the innovation, that the armature in more uniform Circumferential distribution are arranged to the edge of the handle through hole.

Furthermore, according to the innovation, it is advantageous if the anchors both with their side edges as well as with its hook-shaped curved broad surface

Form undercut holding surfaces.

A favorable solution is iicucrüugsgciüäß in that the anchors are encapsulated by the material of the bearing bush.

* According to the innovation, it is also an advantage if

the anchors engage in a thickened central zone of the bearing bush, from which the opposite the bearing bush bore has a support collar with a wider cross-section.

Finally there is another advantageous feature of the innovation that the anchor is cut free and bending are shaped.

As a result of this configuration, an easily manufactured door fitting is more stable created. The anchoring of the bearing bush and thus also of the supporting part assigned to it on the shield is extremely stable. The door fitting is often used for the longest time withstands relatively high stresses emanating from the handle shaft. For the bearing bush the most suitable plastic can be selected, especially because it has an even circumferential distribution provided anchors protruding into the thickened central zone also in turn have a certain amount

The door plate 1 has the passage opening 2 for the lock cylinder xini, the handle passage hole 3, and also the rearwardly directed support edge 4.

Anchors 5 projecting backwards go from the edge of the handle through-hole 3. These are arranged in a uniform circumferential distribution from the edge of the handle passage hole 3. they form both with their side edges 6 and 7 and with their broad surface 8 curved in the shape of a hook undercut fiat surfaces.

With these undercut holding surfaces 6, 7 and iit, the bearing bush 9 is anchored on the shield 1. This is achieved in that the armatures 5 engage in a thickened central zone 10 of the bearing bush 9.

The bearing bush 9 extends with an annular bead 11 to in front of the front surface 1 'of the shield 1.

The bearing bush 9 is integrally formed with a uniform material, extending from the thickened central zone 10 backwards over the support edge 4 of the shield 1 projecting support collar 12, which is provided ^ to in an appropriately sized concentric zem pusher through hole 3 lying hole of the Door or the like to be driven in the detention seat.

The support collar 12 is transversely... Wider than the bearing bush bore 9 ·.

The embodiment shown in Figure 3 differs differs from the solution shown in Figure 2 essentially only in that the anchor do not have broad surfaces curved backwards in the shape of hooks. Rather, the anchors are bent backwards essentially at right angles to the longitudinal plane of the door plate. they practice their holding force is largely only due to the fact that the undercut holding surfaces 6 and 7 are provided, which are formed by the side edges of the armature 5.

An advantageous way of producing the signs according to the innovation is that the armature 5 are encapsulated by the material of the bearing bush 9, that is to say that the door plate 1 placed in a suitable mold and then in the plastic injection molding process with the bearing bush 9 is fitted, which bearing bushing 9 of the same material the support collar 12 is formed.

To generate the anchor itself can be advantageous Manner, especially if it is a stamped sign, which illustrated in Figure 4 Solution to be chosen. The anchor 5 are through

bent backwards, be it in the position pointing backwards as far as possible at a right angle according to FIG. 3 or into the hook-shaped backward bent position according to FIG. 2.

Instead of the Sfit collar 12, other For example, support parts provided in the form of individual spikes occur. Instead of a door sign it can also be a rosette, for example the rosette of a window handle or similar.
