Abstract: A plurality of sanitary mixer fittings, in particular of concealed mixer fittings, form a set of mixer fittings that comprises identical universal connection housings with different cartridges and suitable different cartridges adapters. The universal housings have hot and cold water inlets for connection to the domestic water pipes as well as at least one mixed water outlet for connection e.g. to bath-tub inlets or showers. The relevant cartridge adapter is inserted into a location hole in the universal housings. The water inlets and outlets of the universal housings are flow-connected to water supply openings that are disposed in the inner surfaces of the adapter location hole in the universal housing. The water supply openings are flow-connected, optionally by annular chambers, to outer water supply openings in the outer surfaces of the relevant cartridge adapter. The relevant cartridge is inserted into a cartridge location hole in the relevant cartridge adapter.

Abstract: A hand-held shower comprises a handle through the interior of which the water supply to the shower head is effected, the connection fitting for the shower hose is held in an axially displaceable manner: in a first axial position, the connection fitting is freely rotatable relative to the handle so that the shower hose connected to the hand-held shower is prevented from twisting. In the second axial position of the connection fitting, the free rotatability relative to the handle is suspended by a form closure.

Abstract: A flush type mounting box for sanitary fittings carries on the outer surface of its side walls an annular collar of resilient material. This collar includes as one piece, a sealing region that is displaceable on the outer surface of the side walls, and a flange region, which is arranged to be introduced into the gap between two facing elements of the mounting wall and is fixed there, forming a seal. By this collar, the gap between the access opening in the facing elements and the mounting box can be sealed against moisture penetration. In the case of lining wall systems, corresponding to the distance between the supporting mounting plate of the mounting wall and the facing elements, the sealing region of the collar bears at different points on the outer surface of the side walls of the mounting box.

Abstract: A multifunction hand shower can be used in at least two modes of operation: in the first of these modes of operation, the shower jets emerge from the shower base (3) in a constant stream at relatively high speed and with a small cross-section ("hard jet mode") and in the second mode of operation they emerge at high speed and with a relatively small cross-section, but are intermittently interrupted ("pulse jet mode"). The periodic interruption of the "pulse jets" is ensured by a pulse wheel (23) which is housed in a circular chamber (20) in the housing (1) in such a way that it can rotate. In the "hard jet mode", the rotation of the pulse wheel (23) is interrupted, by a stop (45), in a quite specific angular position which allows the hard jets to emerge from the shower base (3) in a constant stream. To change over to "pulse jet mode", the stop (45) is moved out of the path of movement of a stop (28) which is connected to the pulse wheel (23) such that the pulse wheel (23) is now able to rotate freely.

Abstract: In a known manner, a shower head, particularly for a hand shower, has a bell-shaped housing, which is closed off at the bottom by a shower base (1) and in which at least one water chamber is formed which connects with a water supply channel. The shower base (1) contains a large number of water outlet openings (15), which are made on hose-type jet attachments (11). The hose-type jet attachments (11) extend from a smooth, unbroken, continuous outer surface of the shower base (1) which is free of indentations apart from the water outlet openings (15) into the inside of the housing. In so doing they pass through a hole (3) in the shower base (1), the diameter of which is larger than the outer diameter of the jet attachment (11). In this way, there is formed round the jet attachment (11) a clear circular space (13) which does not open in the outer surface of the shower base (1) but in its inner surface.

Abstract: In a multifunction hand shower the mode of operation is selected by a change-over mechanism which has a slide (56) which has essentially linear movement. This can be set in three different positions. The slide (56) is connected via a guide and cam mechanism (62, 65) to a first change-over device (37) which can be moved into two different positions. The first position is adopted by the first change-over device (37) in the first mode of operation and the second position in the two other modes of operation. A second change-over device (45) can also be moved backwards and forwards between two positions which correspond to the second and a third mode of operation of the shower. Here, a spring (49) forces the second change-over device (45) into a preferred position. Whether the second change-over device (45) reaches this preferred position depends upon the position of a stop (59, 60) which is attached to the slide (56). The slide (56) is moved for preference by a rocker-type manual actuator (53).

Abstract: The shower base (1) of a shower head consists of a rigid perforated plate (1a), which has a number of holes (4, 5). Set into each of the holes (4, 5) in the perforated plate (1a) is a hose-type jet insert (6, 8) made of a flexible material which, owing to its material properties, can be flexed automatically to dislodge limescale deposits. The outer surface of the rigid perforated plate (1a), i.e. the surface of the shower base (1) which is visible to the user from underneath, is essentially completely covered by an impact resistant plate (1b) which is also made of a soft, flexible material. Of course the impact protection plate (1b) has collar-shaped lugs (12) going through it which are preformed on the perforated plate (1a) and which surround at least those hose-type jet inserts (8) which produce the high-power jets owing to their relatively narrow jet channel (9).

Abstract: A shower support bracket can be moved axially on a shower rail and can be locked in various axial positions on the aforesaid rail by means of a clamping device. The clamping device locks on concealed gripping surfaces in a groove at the back of the shower rail. It consists of a clamping piece (7) which has two clamping jaws (7b, 7c) separated from each other by a gap (13). A wedge-shaped expanding projection (14) extends into the gap (13) between the clamping jaws (7b, 7c) such that, as the clamping piece (7) and expanding projection (14) move relative to each other, the two clamping jaws (7b, 7c) move at varying distances apart and by so doing are pushed at varying depths into the receiving hole (5) for the shower rail and in this way are pressed against the gripping surfaces of the shower rail with varying degrees of force.

Abstract: The shower base (1) of a shower head consists of a rigid perforated plate (1a), which has a number of holes (4, 5). Set inside each of the holes (4, 5) in the perforated plate (1a) is a hose-type jet insert (6, 8) made of a flexible material which, owing to its material properties, can be automatically flexed to dislodge limescale deposits. The shower base (1) is sealed against the rest of the shower head, in particular against its housing (2) by means of one or more seals (25, 29). This/these seal(s) (25, 29) is/are made of the same material as the jet inserts (6, 8) and is/are manufactured jointly with these, for preference connected in one piece. In this way, it is not necessary for the seals (25, 29) to be manufactured, kept in store and assembled separately.

Abstract: A sanitary mixer tap contains a first fixed control disc (1) having a first through aperture (4) communicating with a cold water supply and a second through aperture (5) communicating with a hot water supply and laterally inverted in relation to a central plane M--M. Above the first control disc (1) there is a second control disc (2) which can be moved linearly and rotated in relation to the fixed control disc (1) in the prior art manner to alter the quantity and temperature of the mixed water flowing from the mixer tap. The recess (10) in the movable control disc (2), which can be caused to overlap variably with the through apertures (4, 5) in the fixed control disc (1), has a specially shaped control edge (14). This is so designed that, when the sanitary mixer tap is opened, in the centrally rotated position of the movable control disc (2), it first solely brings about an overlap with the through aperture (4) in the fixed control disc (1) connected to the cold water supply.
