The invention relates to a cold and hot water mixer having two push-button valves arranged in parallel inside the body, one connected to a cold water inlet pipe and the other connected to a hot water inlet pipe to a common mixing water outlet, and in which the valve stems are moved into the open against force, is locked in the open position and a new press of the pushbuttons is released to return to the closed position.

A mixer of this type is known from U.S. Patent 1,627,020. Here, a body receiving two push-button valves is arranged below the sink and is operated by means of calipers, and between the push-buttons of the two push-button valves an outlet pipe extends upwards through the rear edge of the sink and is bent forward above the sink.

The object of the invention is to manufacture a pushbutton mixer of the type described above with small dimensions and low manufacturing costs, both as a standing fixture for washbasins and as a wall fixture.

2 58968 This object is achieved according to the invention in that two push-button valves are arranged at the smallest possible distance from each other inside the body, which extends outwards and forwards from the mounting surface at the edge of the sink or on the building wall and from the free end the push-buttons protrude for use. The two pushbuttons can be operated with the same hand individually or simultaneously.

In order to be able to influence the temperature of the mixing water in such a mixer, it is proposed that a rotatable slide valve running transversely to each inlet channel is provided in the body, with which the amounts of water flowing to the push-button valves can be adjusted relative to each other.

In a preferred embodiment, a protective housing is formed on the operating side over the body containing both pushbutton valves, forming an outer shell and provided with an end opening for passage and guidance of pushbuttons and an opening for a short removal opening so that the open edge of the housing abuts and is fixed thereto.

In this way, the actual armature is protected from the outside by a protective housing, which can be made of the desired material, e.g. metal or plastic, inexpensively thin-walled and almost without machining. The body parts are covered on the outside with a protective case and can be made cheaply with an unmachined outer surface.

The invention is described in more detail below with reference to the accompanying drawings.

Figure 1 shows a side view of the sink fitting. Figure 2 shows a top view in section along the line II-II in Figure 1.

Figures 3 and 4 show sections along lines III and IV of Figure 2 through a rotary spool valve passing transversely to both inlet passages.

Figure 5 shows a vertical section through a standing armature for washbasins, in which a valve body containing push-button valves is arranged inside a protective housing.

Figure 6 shows a view in the direction of the arrow VI of Figure 5, push buttons being removed.

Figure 7 shows a vertical section through a wall fixture with a protective housing.

In the embodiment according to Figures 1 and 2, the valve body indicated by reference numeral 1 is fastened in the usual way to the rear of the washbasin 2 by means of a connecting arm 3 through the washbasin 3. Wires 5 and 6 for cold and hot water are soldered to the connecting arm 3, and the wires are down and preferably connected with angle valves to the inlet lines routed through the wall of the building. The valve body 1 has inlet spaces 7 and 8 for cold and hot water, which descend into two parallel inlet ducts 9 and 10. The inlet ducts 9 and 10 continue in larger diameter coaxial body bores in which valves 11 and 12 are arranged on the end side. and 10 opening valve closure members 13 arranged at the free end of the valve stem 28. In the embodiment shown, the valve seats cooperating with the valve closure members 13 are preferably formed of annular plates 14 which are made of sealing material and which are pressed against the shoulder surfaces of the valve body by the valve parts.

Valves 11 and 12 are push-button valves known per se, the push-buttons 15 and 16 of which protrude and are operated from the end side of the body for use. In the exemplary embodiment, the pushbuttons 15 and 16 are rectangular in cross-section and are arranged immediately next to each other and are non-rotatably guided in a suitable recess in the body.

When the pushbuttons 15 and 16 are pressed inwards against the action of the valve closing spring 17, the valve closing members 13 are brought into their open position in a manner known per se, secured to their open position by a locking pin which falls into the groove of the control curve and released with a new push of the pushbuttons.

In front of the valves 11 and 12, in the embodiment shown, a rotary slide valve 20 is arranged in the valve body 1 transversely through the cold and hot water inlet channels 9 and 10, which is sealed between the two inlet channels and with respect to the valve body by means of O-rings 21. This spool valve (rotary slide) is controlled by a rotating pin 22, which can be accessed from the other side of the 58 588 valve body. Inside the valve body 1, the rotary slide 20 at each inlet channel 9 and 10 is provided with notches 23 and 24, which are illustrated in Figures 3 and 4 in the central position of the rotary slide. The notches 23 and 24 are circumferentially displaced relative to each other so that when the rotating slide is rotated by means of the rotating pin 22, the flow of water in the second inlet channel is constricted and in the second inlet opening increases. In this way, the amounts of water flowing to both valves 11 and 12 can be adjusted relative to each other by rotating the circulating slide 20 if the water temperatures have changed or warmer or colder water is desired, the outer end of the valve stem 28 grips the movable shaft 32 17. Connected to the valve 32 are clockwise push-buttons 15 or 16 entering the valve housing, and in the illustrated embodiment the push-buttons have a central hollow pin portion 35 radially resilient in the slots 36 releasably inserted into a corresponding recess in the end side of the shaft 32.

In the embodiment of Figures 5-7, the number 51 denotes a valve body which includes both push-button valves as shown in Figure 2. Push buttons 15 and 16, each equipped with painonappiventtii-gels have the valve body 51 relative to the drive side on the opposite side of the separate inlet openings to which supply lines 54 and 55 is inserted, e.g. soldered. Both pushbutton valves have a common outlet 56 in the valve body 51.

The fitting for washbasins shown in Fig. 5 has a coupling piece 57 for connecting the valve body 51, which is supported by a flange 58 on the edge 2 of the washbasin and extends inside its mounting opening. Inlet pipes 54 and 55 are soldered to the two parallel bores of the switch body 57 and inlet pipes 5 and 6 from the bottom. Inlet pipes 5 and 6 are connected to the cold and hot water pipes protruding from the wall of the house in the usual way behind the sink. The inlet lines 5 and 6 pass loosely through a clamping plate 65, which can be tightened against the underside of the sink edge 2 by means of a clamping screw 68 passed through the coupling piece 57. The inlet pipes 54 and 55 connected to the valve body 51 are bent at an obtuse angle before the ends soldered into the coupling body so that, after installation, the valve body 51 obtains the obliquely upward position shown in Fig. 5.

A protective housing 75 is pushed onto the valve body 51 from the drive side, forming an outer shell and having an opening at one end preferably for passing through and guiding the rectangular pushbuttons 15 and 16 and behind this opening in the expanded center portion 77 of the lower wall opening 78 for obliquely downward short discharge 56. In the installation position, the protective housing 75 rests with its open edge against the edge 2 of the sink.

In the exemplary embodiment, the housing 75 is secured against the sink edge 2 by two screws 84 which are screwed from the drive side to the valve body 51 at diametrically opposed angles (Fig. 6) and which extend against the shoulders 86 arranged inside the housing. In order to access the screws 84, the pushbuttons 15 and 16 are removably inserted into the recesses of the spindle guide arms 32 by a radially resilient central pin 35, as in the embodiment of Figures 1 and 2.

In the wall fitting shown in Fig. 7, the outer jacket 75a, as in Fig. 5, is fixed at its open edge against the wall of the valve body by means of clamping parts 84 which can be screwed into the body from the operating side. In this case, both straight inlet pipes 54 and 55 are placed in the connections of the inlet lines projecting from the wall of the building.

A nozzle 91 acting on the outgoing water jet, e.g. an air bubble nozzle, can be attached to the short outlet 56, as shown in broken lines in Fig. 5. This occurs after the protective case 75 or 75a is attached.

As in the embodiment of Figures 1 and 2, the valve body 51 may be provided with a rotatably sliding valve 20 passing transversely through the inlet ducts leading to the valves to access the mixed water temperature, accessible for use through a side opening in the housing 75 or 75a, for example by a torque knob.
