The pipe is divided into two sections, the first section takes up the cartridge, and that at the two tubing sections a case (7) is arranged, by which a means of actuation for the actuator is provided. The cartridge additionally mixes cold and warm water. The actuation is designed as a straight line lever.

Description

The invention relates to a water fitting according to the preamble of claim 1.

Such a water fitting is known, for example, by the water fitting sold under the name "Arcor" from Hansgrohe, in which a mixer cartridge is integrated in the second pipe and can be operated with a single-handed bow handle. The bow handle is attached to the cartridge via two attachment points arranged tangentially to the tube. The second tube is split and the cartridge inserted flush at the division point. Cartridge and bow handle are designed so that the insertion points are visible as joints and that the regulation of the discharge of water by pulling the bow handle to the user and vice versa takes place.

A disadvantage of this water fitting is that the said joints and attachment points are difficult to access and can be cleaned, that the movement of the bow handle is unusual and must be practiced and that when using the bow handle with dirty hand also contamination of the nearby first tube or fitting body threatens.

From EP-A2-0 245 905 a water fitting is known which comprises a first pipe having a straight pipe part in the upper end region and a bent pipe part in the lower end region and a second pipe with a bent pipe part in the upper end region and a straight pipe part in the lower end region having. The first tube is arranged vertically pivotable with its bent pipe part on a rotatable dome, wherein the dome is provided with an actuating lever provided with a cartridge which is horizontally rotatable for controlling the temperature and the water discharge amount. The straight tube part of the first tube can be pulled out of the straight tube part of the second tube part and rotated relative thereto. Further, a third pipe is rotatably arranged in a direction perpendicular to the tube axis of rotation on the bent tube part of the second tube.

Although this known fitting can steer the water jet emitted by it in any desired direction, but is disadvantageous that many sealed rotary and Ausziehstellen and components are necessary that the handling of the fitting for a given water jet direction is cumbersome and that the cartridge with the Actuator is relatively far away from the water outlet point.

From DE-A1-31 38 414 a water outlet fitting is known in which a pipe with an outlet nozzle or a hand shower is connected via a hose to the supply line, wherein the pipe supported by a pivotally mounted, for example, on a washing or sink fitting body is. For selectively positioning the outlet mouthpiece in a guide of the tube latching means are provided which cause a locking of the outlet mouthpiece in the selected position. This locking means may be formed by a held in the guide, spring-loaded ball and by a plurality of parallel rows of tooth gaps on the pipe, which allow a limited rotation and locking of the outlet nozzle.

A disadvantage is considered that the water jet can be discharged only in limited directions and that no water regulation attached to the outlet mouth piece and the hand shower and therefore must be operated separately.

The object of the invention is to provide a water fitting referred to in the preamble of claim 1, which can be easily constructed and handled and yet allows a wide range of Wasserabgaberichtungen.

This object is achieved with the features of claim 1.

This version is particularly suitable as a bidet mixer. Oriented upwards by 180 °, the parabolic jet can be used for a facial shower.

A further embodiment of the invention provides that the second tube is removable from the first tube and a flexible water inlet hose is connected to the inner end of the second tube. In this second embodiment, the second tube can be used as a hand shower, so that the water jet can be directed in all directions.

According to a further embodiment of the invention, the second tube in the first tube can be pushed flush. This facilitates the cleaning of the water fitting.

According to a further embodiment of the invention, a cartridge adjusting the amount of water discharge is arranged eccentrically in the first tube and the water inlet hose is guided past the cartridge and connected thereto. Therefore, the cartridge can be moved close to the vicinity of the joint of the first pipe and the second pipe.

According to an expedient, further embodiment of the invention, the cartridge is designed such that it additionally mixes cold and hot water.

According to a further embodiment, the water inlet hose is the tube provided for a hand shower. Thus, a separate hand shower can be saved.

A further embodiment of the invention is such that the first tube is divided into two attachable sections, that the one portion receives the cartridge with a projecting from this section to the other portion actuating means of the cartridge, that an actuating lever is connected to the actuating means and that the other portion is provided with a recess which limits the movement of the actuating lever. This simplifies the assembly of the cartridge in the first tube.

According to another embodiment, a joint of the two sections of the first tube and the recess overlapping, movable sleeve is provided, which is forcibly guided by means of the actuating lever. Joint and recess and their possible contamination are no longer visible and on the other hand can be easily cleaned after separation of the operating lever and moving the sleeve.

According to a simple, further embodiment of the invention, the actuating lever is guided through an opening of the sleeve.

Such, provided with an actuating lever cartridge can be reached by left-handers as well as right-handed equally. When operating the operating lever contamination of the valve body by soap and lime is excluded.
