Operating handle

The invention relates to an operating handle for a device for switching between two types of beam exit with hand showers or the like.

Such a device for a hand shower is known from DE-PS 23 24 077. With this facility is A slide switch is provided for switching over, with an automatic return to a preferred water outlet not possible. In addition, the device requires a lot of space and is parallel to the handle to arrange the hand shower.

The invention is based on the object of providing a handle for the actuation of an inexpensive to manufacture To create switching valve for showers, which allows easy handling of the changeover and above also meets the hygienic and aesthetic requirements in the sanitary area.

This object is achieved according to the invention by the in the characterizing Part of claim 1 specified features solved. Further embodiments of the invention are shown in the claims 2 to 4 specified.

The advantages that can be achieved with the invention are, in particular, that the operating handle according to the invention is formed in the form of a bracket led around the shower head, this

can be brought into any position of the switching valve with one hand. In addition, it will be rit dem Actuating handle enables switching valves that automatically return to a preferred outflow position when the water flow is shut off, manually in to switch each setting position when the water escapes.

The actuating handle, which is designed as a bracket, can be advantageous be embedded in a groove formed in the shower head, creating a harmonious integration of the operating handle is reached in the shower head. The groove and the operating handle are expediently dimensioned in such a way that that any water or dirt particles that have penetrated can easily be flushed out of the groove. In the end the actuating handle, which is designed as an annular bracket, can have a convex curvature on the outer surface, so that particularly favorable ergonomic operating properties can be achieved.

An embodiment of the invention is shown in the drawing and is explained in more detail below. It shows

FIG. 1 shows a hand shower in side view, partially in section;

FIG. 2 shows the hand shower according to FIG. 1 in section plane II;
10

Figure 3 shows the hand shower according to Figure 1 in plan view.

The hand shower shown in the drawing consists of a handle 2 and a shower head 1. On the handle 2, a hose (not shown in the drawing) for the water supply can be connected by means of a quick coupling 21 be connected.

In a recessed in the tilt area of the shower head 1 A ring-shaped bracket 3 is inserted into groove 11. The bracket 3 is attached to a spindle 4 Snap connection firmly connected. The spindle 4 and thus the bracket 3 is in a neutral central position by springs held, the water outflow in the preferred outflow direction via a water jet aerator 12 is delivered. If a switchover is now desired, a pressure in the axial direction of the spindle 4 is sufficient the bracket 3 and a valve cone 41 blocks the drainage in the water jet aerator 12 and clears the way for a shower jet generator 13. If the bracket 3 is now released, it returns to its own due to the spring force neutral center position back, while the valve cone due to the existing water pressure in the newly assumed Position is held. Only when the water inflow

is turned off, the valve cone 41 is returned to its preferred position by a return spring so that in turn the outflow via the water jet aerator 12 is released. Should a renewed switch from the shower jet generator during operation 13 can be done on the water jet aerator 12 without shutting off the water supply, so old With the help of the ring-shaped bracket of the valve cone 41 over the spindle 4 in its preferred position against the pending Water pressure to be withdrawn.

A particularly good grip and positioning option To achieve, the bracket 3 is provided on its outer surface old with a curvature 31, the curvature approximately one Has a radius of 0.5 of the diameter of the shower head. For safe guidance of the bracket 3 are at the Outer surface guide ribs 32 formed, which on accordingly formed surfaces of the shower head 1 are sliding.
