Description

The invention relates to a sanitary shower with a shower head according to the preamble of claim 1.

In a sanitary shower of higher comfort class, the shower head can have a keypad, with the showering process in any way different shower spray types are applicable to each other and / or separately.

From the DE 10 2011 017 434 A1 is a sanitary shower is known, the shower head has at least two keypads exhibiting keypad. The feeler elements are, with the interposition of a feeler mechanism in operative connection with valves in the shower head. With manual pressure actuation of these feeler elements the shower spray type is adjustable. Each of the sensing elements is spring-biased to a closed position in which a flow path in the showerhead is closed. In a manual pressure actuation, the respective probe element is pressed over a first stroke in an open position in which the flow path is open and in which a molded on the pressed probe element latching contour is in releasable latching engagement with a mating contour of an adjustable control slide. The control slide can be adjusted to release this locking engagement in an unlocking position in which the Tastelement-locking contour and the control slide counter contour are disengaged.

To release this latching engagement, the already-pressed feeler element can be overridden starting from its depressed closed position over a second stroke to a release position. In the release position, a control surface of the probe element pushes the control slide in the above-mentioned unlocking position. This has the consequence that all other sensing elements are reset from their open position to their closed position. When raising the over-pressed into the release position sensing element of the control carriage is moved back from its unlocked position in the direction of its locking position. This ensures that the pressed into the release position probe element in the open position remains held in latching engagement with the control slide and - in contrast to the other probe elements - does not return to the closed position (ie initial position). When the shower faucet is opened so always a jet of water exiting the shower head, whereby the non-pressure-resistant shower hose is not excessively pressure-loaded.

In a generic feeler mechanism, the key element detent contour can optionally be an elastically yielding detent arm, which is formed on the feeler element and has a detent cam at its free end. The latching arm must on the one hand be designed sufficiently rigid component to ensure a secure latching engagement in the open position of the probe element. On the other hand, the latching arm must also be made sufficiently resilient so that the latching engagement when overpressing the feeler element in the release position is easily solvable.

For the above tactile mechanism is only a greatly reduced space available. Therefore, the sensing elements have only a reduced material thickness. This can lead to slight deformations of the sensing elements in a printing operation. However, such deformations may reduce the travel ranges available for motion transmission on the control carriage. When pressing the sensing elements, therefore, the pressure forces must be increased accordingly to achieve a perfect tactile actuation, which is disadvantageous in terms of a comfortable feel.

The object of the invention is to provide a sanitary shower with a shower head, in which the sensing elements are reliably and comfortably operated.

The object is solved by the features of claim 1. Preferred embodiments of the invention are disclosed in the subclaims.

In the invention, the problem has been recognized that in the above-mentioned latching arm, the dual function, namely providing a reliable locking engagement and a smooth release of the latching engagement, is difficult to accomplish. Against this background, according to the characterizing part of claim 1, the locking contour no longer resilient, but rather component-rigid formed on the respective probe element. In return, the cooperating with the locking contour counter contour is elastically yielding adjustable on the control slide, namely adjustable from a locking position to a release position. In this way, in a sensing operation of the probe element from the closed position to its open position, the control slide counter contour can be brought under elastic deformation with the bausteilsteifen Tastelement-locking contour in engagement.

For a comfortable operation of the keypad is a simple and reliable release of the locking engagement between the probe control contour and the control slide counter contour of great relevance. Against this background, the stroke of the probe element can be divided into a first stroke between its closed position and its open position and a subsequent second stroke from its open position to a release position. The release position is based on the Open position achieved by an additional overpressure of the probe element. In the release position, a control surface of the probe element presses on a corresponding control surface of the control slide, whereby it is pressed into an unlocking position.

Upon depression of the feeler element from its closed position into its open position (i.e., during a first stroke), the control slide remains stationary without adjustment movement in the direction of adjustment. Only upon override from the open position to the release position (i.e., during a second stroke) is a probe control surface coupled in motion to the control carriage and urging the control carriage into the unlocked position.

In the unlocking position of the control slide, a component part rigidly formed on the feeler element can preferably press the control slide counter contour from its rest position into its release position. In the release position of the locking engagement between the control slide counter contour and the Tastelement-catch contour is solved. That is, with the above-mentioned overpressure of the feeler element in its release position, the control slide counter contour comes into abutment with the component-rigid feeler-trigger surface, which adjusts the control slide counter contour elastically yielding in its release position.

In a preferred technical realization of the control slide can be made in two parts, with a component-rigid base body and a spring-mounted there locking element. On the spring-mounted locking element of the control slide, the control slide counter contour can be formed. In addition, a triggering surface corresponding to the feeler-triggering surface may be formed on the spring-mounted locking element. In contrast, the Main body of the control slide have a ramp-shaped control surface. In the release position, the probe element presses against the ramp-shaped control surface of the control slide and pushes it into its unlocked position.

The at least first and second probe element preferably act together on actuation of the first probe element as follows. Thus, to reset the first probe element from its open position to its closed position, the second probe element can be pressed into its release position. In the release position, due to the movement couplings set out above, the control slide is moved into the unlocking position, in which a latching engagement between the latching contours of the first / second feeler elements and the corresponding control slide counter contours is achieved. In this way, the first probe element readily jumps back into its initial position, that is to say into the closed position. When raising the second probe element, however, the control slide is led out of its unlocked position. As a result, the second probe element is not moved back into its closed position, but rather remains in latching engagement with the control slide counter contour. If necessary, in the manner described above, a plurality of first feeler elements can also be reset simultaneously from an open position to a closed position. In addition, any other probe element can be used as a second probe element for the provision of a first probe element. As a result, a provision with any of the remaining existing buttons or sensing elements is possible.

In terms of component reduction, it is advantageous if the control slide counter contours and / or trigger surfaces provided for each probe element are formed on a common, preferably integrally formed, spring-mounted locking element.

The advantageous embodiments and / or further developments of the invention explained above and / or reproduced in the subclaims can be used individually or else in any desired combination except, for example, in the case of clear dependencies or incompatible alternatives.

The invention and its advantageous embodiments and further developments and advantages thereof are explained in more detail below with reference to drawings.

In the Fig. 1 is shown a shower head of a sanitary shower. The shower head has at its top a keypad 1 with four buttons 2 to 5, with the help of different spray types are arbitrarily applicable to each other and / or separately. The buttons 2 to 5 of the keypad 1 are with the interposition of a described with reference to the following figures tactile mechanism 7 in operative connection with control valves, not shown, with the help flow paths in the shower head to adjust the Brausestrahlart be opened or closed. The buttons 2 to 5 are manually pressure-actuated, wherein the sensing mechanism 7 is designed so that always one of the buttons 2 to 5 is held in its open position O, to avoid excessive pressurization of the per se not pressure-resistant executed shower hose 9. To reset indented buttons 2 to 5, one of the buttons is pressed into a release position F described later, in which - with the exception of the manually depressed button - the other button back to the starting position, that is in the closed position G, jump back. The pressed into the release position F button remains in contrast when returning in its open position O, to avoid the aforementioned pressure load of the shower hose 9.

In the FIGS. 2 and 3 the tactile mechanism 7 is shown in each case in a different perspective view. Accordingly, the feeler mechanism 7 four sensing elements 11, 12, 13, 14, which transmit a manual pressure actuation of the respective button 2 to 5 via a shaft 17 to the control valve, not shown. The feeler elements 11 to 14 are each stroke-adjustable in the vertical direction z. In addition, the feeler elements 11 to 14 are arranged in pairs outside of a stroke liftable in a depth direction y control carriage 19. The control slide 19 is in the depth direction y by means of a return spring 21 in a locking position V ( FIGS. 2 and 3 ) and against the return spring 21 in an unlocked position E ( Fig. 10 ) adjustable. Like from the Fig. 5 to 12 further shows, the control slide 19 is made in two parts, with a component-rigid, upper base body 23 and a resiliently mounted on its underside locking element 25th

In the FIGS. 5 and 6 are the opposing feeler elements 11 and 12 of the feeler mechanism 7 in its initial position, that is, in a closed position G, shown in which they with a restoring force F _R ( Fig. 5 ) are pressed. In the closed position G is a locking contour 27, that is, a locking cam, the respective probe element 11, 12 in a recess 29 (only in the Fig. 7a shown) between the base body 23 and the locking element 25. The locking cam 27 is component-rigidly formed on the sensing element 11.

By manual pressure actuation, the probe element 11 of his in the FIGS. 5 and 6 shown closed position G via a first stroke Δh ₁ in his in the FIGS. 7 and 8 shown open position O are adjusted. During the lifting movement into the open position O, the component-rigid locking cam 27 of the feeler element 11 presses according to FIG Fig. 7a against a control slide counter contour 31, which is elastically yielding adjustable formed on the spring-mounted locking element 25. The control slide counter contour 31 is thereby moved from its latching position R (FIG. Fig. 7a ) under construction of a restoring force in his in the Fig. 7a dashed indicated release position A adjusted and reset when overcoming the mating contour 31 back into its rest position R, in which the counter contour 31 is engaged by the locking cam 27 of the probe element 11 ( Fig. 7 ). In the open position O of the probe element 11 is thus the locking contour 27 of the probe element 11 in latching engagement with the corresponding mating contour 31 of the spring-mounted locking element 25 of the control slide 19th

In the same way, if appropriate, the further feeler elements 12, 13, 14 are pressed into their open position O.

In order to return the optionally-pressed feeler elements 12, 13, 14 back to the closed position G, the feeler element 11 via a second stroke .DELTA.h ₂ of the in the Fig. 7 shown open position O further into a in the FIGS. 9 and 10 shown release position F are suppressed. During the lifting movement into the release position F, a ramp-shaped control surface 33 (FIG. Fig. 10 ) of the probe element 11 against a corresponding, also ramp-shaped control surface 35 (FIG. Fig. 10 ) of the main body 23 of the control carriage 19, whereby the control slide 19 against the return spring 21 by a travel Δy in the Bautiefenrichtung y up to its unlocking position E ( Fig. 10 ) is moved.

With the adjusting movement .DELTA.y up to the unlocking position E, the release surfaces 39 formed on the locking element 25 press (FIG. Fig. 9 and 11 ) against the corresponding component-rigid release surfaces 37 (FIG. Fig. 12 ) of the feeler elements 11 to 14, whereby the mating contours 31 on the locking element 25 of the locking position R elastically yielding in the release position A ( Fig. 9a ) are relocated. As a result, the latching engagement between the latching contours 27 of the feeler elements and the counter contours 31 of the locking element 25 is released. Optionally located in the open position O feeler elements 12 to 14 can therefore jump back into its closed position G while reducing the restoring force F _R.

The return to the closed position G takes place with the exception of the pressure-actuated into the release position F feeler 11. By pushing up to the release position F pressure-actuated probe element 11, namely, the control slide 19 moves back again from its unlocked position E. Thus, the locking contour 27 is no longer at the Counter contour 31 are passed, but locked this again with the mating contour 31 of the control carriage 19, so that the probe element 11 is held in the open position O.
