Constituents are hardenable rzen (s <B <. plastic of the button) or thermoplastic Barzen (z <B <-Saperpolysmid TOder. Olyvinylchlor & d) given if prepared with the addition of suitable fillers.

According to the innovation, the keys can be used using hardenable resins by the casting or: molding process and, in the case of thermoplastic resins, by injection molding or Impact press process be produced. Also can do the same using sound Laminates such as hard paper or hard tissue are made.

The keys proposed after the innovation have the following: aden Yorteile The manufacturing process is simple and cheap, with no special Difficulties arise. Because of the significantly lower specific weight are they relatively light. Another advantage is that they don't rust and also that they do not make a rattling noise and that they are made in color can.

Since plastic can generally be produced in any color, can use the key depending on the size or size and shape of the coupling used Part to be made in different colors, so that the keys on this Way can be distinguished quickly and reliably.

Instead of making the keys entirely from colored plastic, you can but also be proceeded in such a way that preferably the highly stressed parts of the same consist of a metal part which is surrounded by the plastic and which in particular is encapsulated or pressed with the plastic or plastic coating.

According to the innovation, keys of various types can be produced especially those for pulling up the spring drives of children's toys, Time switches or drives, in particular also for clocks.

In general, a distinction is made here between two types of wrench, namely so-called socket wrenches, which have a three-, four- or hexagonal hole on a correspondingly shaped- ten dome in a similar hole in the part to be pulled can be inserted and, on the other hand, a key with a screwdriver thread that either has an internally threaded hole for the Screw it onto the winding dome or 3idedo2m. wear. Such winding keys are made with different Zrossen-vl-elecki- bores or mandrels are provided according to the SrSBe 'and ke des? ederlaufwerkes or the winding part provided there. When producing such a key from colored plastic, it is possible without difficulty to carry out the different key sizes in different colors, so that the right key can be selected immediately on the basis of the color. With clocks, especially with alarm clocks, are usually Used wrenches and often keys, one of which with left-hand thread and the other with right-hand thread. In this case, too, a quick differentiation can be achieved through suitable coloring.

@The figure shows two exemplary embodiments of the innovation. In the illustration: FIG. 1 shows one that can be used for a toy, for example open-ended with a square hole and Fig. 2, for example, to open a Alarm clock usable key with screw thread.

In the key shown in Fig. 1, the square bore inside the completely made of plastic Key 2. The key shown in FIG. 2 is a metal sleeve 5 with internal thread 4 is provided by the made of plastic key 5 surrounded, in particular is overmolded or overmolded.
