"Rotary handle for sanitary fittings"

The innovation relates to a rotary handle for sanitary fittings with a cap made of plastic, especially plastic glass, suitable for mounting on a spindle provided with grooves r.

Rotary handles for sanitary fittings made of plastic glass are known in compact form. There are also those with injected metal parts. In both embodiments, the Use cracks due to tension.

The task of the innovation is to provide a twist grip of the type mentioned at the beginning Kind to train in such a way that this is avoided. aside from that

the innovation is based on the endeavor, an economic one To ensure production of the twist grip. The items bollöii can be produced as cheaply as possible.

The solution to this problem with a rotary handle of the type mentioned at the beginning Type consists in that an insert part is provided for transmitting the torque from the cap to the spindle made of a plastic corresponding to the function and that the Einaatzteil with a grooved, molded Cylinder is inserted into a likewise molded with grooved socket of the cap and that it in turn has a Has grooved socket for the spindle.

According to the further innovation, the insert is through a screw inserted from below and one inserted from above Mother held.

The innovation extends further to the suggestion of a cuff that is suitable for clipping and that extends the cap at the bottom to be provided, which is held by a molded plate of the Einaatzteiles.

Finally, the innovation extends to all claimed, described and drawn features.

An embodiment of the innovation is below Described in more detail with reference to the drawings.

Fig. 1 shows a longitudinal section through the rotary handle, Fig. 2 is a plan view.

The cap made of plastic, preferably plastic glass, is designated as a whole with Io. In order to make them hand-fit, ribs 11 are provided on the outside. Otherwise, the exterior Shape of the cap be designed in terms of taste.

The inside of the cap has an integrally formed socket 12, the inner surface 13 of which is provided with grooves. In the socket 12 is the Cylinder 21 of an insert part 2o also made of plastic is inserted, with grooves on the outside of the cylinder are provided that correspond to those of the socket. These grooves result in the non-rotatable connection between Cap and insert.

The insert part in turn has an integrally formed bush 22, also provided with grooves, into which the grooved spindle (not shown) the valve is inserted.

The combination of cap - bushing - cylinder - insert part results in reliable transmission of the torque

Functional plastic, i.e. one that is compatible with the torque transmission has the necessary material properties. This allows the torques over j safely transfer a relatively small radius to the spindle will. The torque is transmitted from the cap to the insert part at the socket over the larger radius. The material of the cap is thus less stressed. You can choose the material of the same according to taste choose (plastic glass).

The insert part 2o is held by the screw 3o, the can also be made of plastic. It is inserted from below into a through opening 23 of the insert part and screwed into a metallic nut 31 which is inserted into the top of the cap. The nut 31 also holds a flush one Marker disc 32.

A plate 24 is formed on the insert part below. With this plate the cuff 4o, which can be made of metal, is held on a collar 42 at the bottom of the surface 19 of the cap Io so that the cuff forms the lower extension of the cap. The sleeve is used to attach to a retaining ring 44 of the fitting, this retaining ring in an annular groove 43 of the Msnsjhette clicks into place. This locking makes the entire Dr' -iff

secured in its axial position.

14 are grooves on the inside of the cap, further grooves 15 and are on the end face of the socket 12 or on the inside on a conical surface. These grooves should be used when using plastic glass Prevent insight into the functional parts inside the rotary handle by refraction or light reflection.

One advantage of the twist grip according to the innovation is that it ensures a functionally reliable torque transmission by using a functional plastic where there are large forces, namely on the spindle, while you can use a corresponding plastic for the decorative part of the rotary handle.

Overall, parts are used as far as possible that are malleable as they are used and no post-processing need more. Because of this, a twist grip can be used produce economically after the innovation.

The insert can also be used to hold the cuff.

Metal can be used for the cuff as well as for the nut 31 use, which in combination with the art

fabric glass results in an appealing design. By using The handle is thermally insulated from plastic for the cap. There is also the possibility of the- ^ cppe outside as desired to be designed according to decorative aspects using the same functional parts.

All parts are held together by screw and nut, which only requires one work step during assembly.
