The innovation relates to a key, in particular to a key made of die-cast zinc or brass, as it is preferred for. tumbler-free furniture locks are used. As a result of the The working surface of the key bit is subject to the soft material used in such keys mainly for price reasons an early wear, so that in the long run a correct attack on the bolt and a safe control of the same no longer is guaranteed.

It is already known in the case of plastic keys, the base body, i.e. in particular the key shaft, key ring and part of the To make beards from softer plastic and the actual otronic part of the beard, which has the beard steps, from harder Manufacture plastic. The solution is disadvantageous in terms of manufacturing technology, that it would be far more advanced, the entire key

Mold from the harder plastic, especially a significant price difference in the material used is independent of the hardness of the same.

The task of the present innovation is to pick one out of the previously known material, such as die-cast zinc or brass made key in the main stress zone of the beard in increased Equip wear resistance without a significantly more complicated Production occurs and without the functional safety of the Affect the key au.

According to the inflation, this is achieved by the fact that the key shank parallel surface with a key abrasion-resistant curved bracket is occupied, in it except ± aure '.- ::; essjr dor thickness corresponds to the b '\ rtes, and which iait their ends in linterschnenungcü on the side surfaces of the bread; r- ^ t.

This basic body becomes equipped in the most favorable way with the abrasion protection. The 3 "pieces takes place by clinging around the more abrasion-resistant part.

Afford. In addition to the favorable mounting, the undercuts have the effect that the beard thickness is not increased by the curved bracket.

The subject of the innovation is shown on the drawing in an exemplary embodiment, namely shows:

Fig. 1 of the key in plan view,

Fig. 2, on an enlarged scale, a side view of the beard end

of the key, Fig. 3 a section along the line AB in Fig. 2.

The key has the Sr.haft 1 and the beard 2. These two toilets, which form the basic body of the key, are preferably made of die-cast zinc or brass. A curved clamp 3, which is made of spring steel and whose outer diameter: corresponds to the thickness y of the beard 2, is pushed onto the beard 2 from the front or back. The clamp 3 is open on one side, so that the ends k and 5 arise. These ends occur in undercuts 6, which are located on the key bit on the side surfaces. In this way , the clamp 3 is held without special fastening means, in particular when it is pushed onto the elastically resilient clamp seat. The curved shape is very beneficial to the creation of such an elastic press fit, without any deformations that are unfavorable in terms of locking technology when the clamp is placed.

As can be seen from the drawing , the working surface of the key is now formed by this -.- abrasion-resistant clip 3 made of spring steel, so that locking problems resulting from wear and tear of the key are excluded.
