Definitions

• the invention relates to a shower head with a housing in which a valve is arranged, which has a closure body, which is adjustable to switch the beam with an actuator between two closing positions.
• a shower head of this type has become known for example from DE 198 03 554 A.
• This shower head is intended in particular for a pull-out shower or dishwashing spray.
• the shower head is connected to a hose line, which is guided displaceably in a pipe bend.
• the shower head can be pulled out of the pipe bend from below.
• Such showers are also referred to as "pull-down" jets.
• the valve is a change-over valve that can be switched on a lever, so that optionally two different jet formations are possible.
• the lever is arranged invisibly under a rubber-elastic membrane. The changeover takes place at two different spaced apart actuating points of the membrane.
• a pull-out spray has also become known in the prior art from EP 1 418 007 A.
• a lever is also arranged under a rubber-elastic membrane for the operation. This acts via a toggle wedge on the closure body of the switching valve to move it between the two positions.
• a dishwashing spray is known, which has as an actuating element a lever arranged on the outside. In a pivoted position, this lever can be fixed to a retaining ring. To change this retaining ring must be rotated. The operation is comparatively cumbersome here.
• EP 0 704 252 A discloses a showerhead with a handle, which is also arranged under a rubber-elastic membrane.
• GB 2 185 019 A discloses a showerhead which has a laterally projecting lever for actuating an outlet valve. However, this shower can not be switched between two spray modes.
• the US 6,378,790 B discloses a shower, which has a rotary lever for actuation. This rotary lever is projecting outside the housing.
• the invention is based on the Aufgäbe to create a shower head of the type mentioned, which is easier to operate and can also be made inexpensively from a few parts.
• a generic shower head characterized in that the actuating device has a projecting on the outside of the housing rotary knob which is limited to adjust the closure body by hand rotatably and operatively connected to the closure body.
• the wheel allows a very simple one-point operation and one-hand operation. No other position needs to be sought to change the beam type, which is especially important in the case of a pull-out spray.
• the operation for switching the valve takes place, for example, with the thumb of the hand, which holds the shower head. Since the rotary knob protrudes on the outside and thus is not hidden under a membrane, it is also clear on first use, how and where to operate.
• the shower head is particularly suitable for a pull-out shower.
• a valve tube is arranged in the housing and that the rotary wheel is rotatably mounted on the outside of this valve tube.
• the rotary wheel can be inserted through an opening of the housing in this.
• the rotary knob is finally inserted through the opening of the housing after placing the housing.
• the insertion of the rotary wheel is then particularly simple and reliable, if it is latched onto a bearing part arranged in the housing.
• This bearing part is preferably a bearing block, which is integrally formed on said valve tube.
• the rotary wheel is connected to a connecting part with the closure body.
• This connecting part can be positively or frictionally connected to the rotary knob in a simple manner.
• the connection is particularly simple if, according to a development of the invention, the connecting part has an opening at one end, into which engages an attachment of the rotary wheel.
• Such a compound is relatively insensitive to tolerances.
• the assembly is also very simple and allows the above-mentioned locking connection of the rotary wheel with a bearing block of the valve tube.
• the connecting part is displaceably mounted on said valve tube.
• bearing parts are formed on the outside of the valve tube, in which the connecting part can be inserted laterally.
• the connecting part is preferably located in a gap between said valve tube and the housing.
• the rotary wheel has a pin as a driver, which projects substantially radially from the axis of rotation of the rotary wheel.
• This pin is preferably positively connected to the closure body operatively connected. This allows a very simple and reliable construction.
• the rotary wheel is frictionally engaged with the closure body operatively.
• the rotary wheel preferably has a friction surface, which bears against a corresponding friction surface of the closure body.
• this friction surface is arranged on a connecting part and flat.
• the rotary wheel is connected to a hinge part with the closure body. This allows a one-piece design of the rotary wheel and the connecting part.
• the rotary wheel can be manufactured with the connecting part, for example by injection molding as a part. This allows an even simpler and cheaper construction.
• the hinge part has at least one film hinge, preferably two spaced-apart film hinges.
• the hinge part at one end of a two-armed lever which engages with an arm on the closure body to move it. This allows a particularly simple construction with few individual parts.
• Tooth connection with the closure body is operatively connected. This allows a particularly reliable connection between the rotary knob and the closure body.

• Suitable inserts 34 are known in the art and these need not be further explained here.
• a valve V which is a diverter valve and has a closure body 10, on which a connecting rod 12 is formed, which protrudes through a passage 7 of the water guide tube 3.
• the closure body 10 can be moved in the longitudinal direction of the connecting rod 12 limited. If, in FIG. 1, the closure body 10 is moved downwards, a spring 13 is tensioned. In the position shown, a sealing body 11 bears against a valve seat 9. If the closure body 10 is moved downward against the retroactive force of the spring 13, the water guide channel 6 is connected to a space 17 and the outlet openings 15. If the closure body 10 is in the lower position, it rests against a rubber-elastic sealing body 14 and thus closes the connection of the water guide channel 6 with the jet former 16.

• the rotary wheel 33 can be turned rocker-like around the rotation axis 24 in the directions of the double arrow 23, it has on the outer surface 21 a recess 22 which forms two opposite touch surfaces A and B.
• the rotary wheel 33 pivots clockwise about the rotation axis 24 and thereby the closure body 10 is moved downward in FIG.
• the sealing body 11 thus lifts off from the valve seat 9 and thus water can escape through the outlet openings 15.
• the rotary wheel 33 pivots back into the position shown in FIG. For both pivoting movements of the thumb from the rotary wheel 33 does not have to be lifted. It is thus possible a so-called one-point operation.
• the rotary wheel 33 has a pin-shaped bent projection 26, which engages in a passage 27 of the connecting part 28.
• the projection 26 forms a driver, with which the pivoting movement of the rotary wheel 33 is converted into a linear movement of the connecting part 28.
• the rotary wheel 33 has a recess 25 on the back side.
• the connecting part 28 is a rod, which is firmly connected in Figure 1 at the lower end by means of a connection 32 with the connecting rod 12.
• the connection 32 may be a clamping connection, latching connection, an adhesive connection or the like.
• two bearing parts 31 are integrally formed on the wall 30, on which the connecting part 28 is inserted laterally.
