Abstract

The invention relates to a concealed sanitary fitting (1), comprising a housing (40) with connectors (9, 10, 11), for connection to at least one domestic water supply, with a bath outlet and a shower head. A valve is arranged in a first housing chamber of the housing (40), controlling at least one water flow. A switching device is arranged in a second housing chamber (41) of the housing (40), by means of which water exiting the valve may be selectively run to the connector (10), for connection to the bath outlet, or to the connector, for connection to the shower head. Said housing chamber (41) is arranged axially (with relation to the housing chamber for the valve) behind the housing chamber for the valve when viewed from outside. The valve shaft (12) for the switching device extends radially out of the housing (40) and the operating mechanism for the switching device is embodied such that the same can connect a manual operating body (23), arranged in the vicinity of a cover rosette (6), to the valve shaft (12) of the switching device with differing separations between the cover rosette (6) and the switching device. The cover rosette (6) can thus be kept small, which is desirable on aesthetic grounds.

Description

Sanitary concealed fitting

The invention relates to a sanitary concealed fitting with

a) a housing having at least one connection for connection to a domestic water pipe, a connection for connection to a bath outlet and an An¬ connection for connection to a shower;

b) a arranged in a first receiving space of the housing valve which controls at least one stream of water;

c) arranged in a second receiving space of the housing, a valve stem having Um- adjusting device with which the water exiting the valve can be selectively directed to the connectable to the tub outlet connection or to the connectable to the shower connection;

d) a cover escutcheon, which closes the wall recess to the outside in the case of a built-in flush-mounted fitting;

e) an actuator for the changeover device, which comprises;

ea) a hand actuator arranged in the vicinity of the cover rosette;

eb) a hand-operated actuator with the valve Shaft of the switching device connecting Be¬ actuating mechanism.

In the present case, the terms "axial" and "radial" are used to designate directions. By "axial" is meant a direction that is perpendicular to the plane of extension of the building wall in which the concealed fitting is to be installed. This direction generally coincides with the axis of the receiving opening for the water flow controlling valve. Each direction perpendicular thereto, which thus runs parallel to the plane of extension of the building wall in the installed state of the concealed fitting, is here called "radial".

In known sanitary concealed fittings of the type mentioned above, the second receiving space, which contains the switching device, laterally from the first receiving space in which the water-controlling valve is located. The axes of both receiving spaces ver¬ run in the o. Meaning "axial" and parallel to each other. The manual actuating element is a pull knob, which is connected to the valve stem of the changeover device via a rod which in this case acts as an actuating mechanism. To change the water flow, the pull knob is pulled away from the rosette in the axial direction; in the position in which the water flows to the shower head, the pull knob has a clear distance from the outside of the Abdeckro- sette.

Due to the fact that in these known sanitary flush-mounted fittings the two receiving spaces are offset from one another in a lateral (radial) direction, the flush-mounted fitting also builds in this direction moderately large. This inevitably has the consequence that the covering walls covering Äbdeckrosette large area. However, this is not always desirable for aesthetic reasons.

The object of the present invention is to design a sanitary flush-mounted fitting of the type mentioned at the outset such that it builds in the radial direction and thus manages with smaller covering rosettes.

This object is achieved in that

f) the receiving space for the Umstellvorrichtung seen from the outside axially behind the receiving space for the valve;

g) the valve stem of the UmsteilVorrichtung is led out radially from the housing;

h) the actuating mechanism is designed so that it can connect the manual actuating element at different distances between the covering rosette and the changeover device with the valve stem of the Um- adjusting device.

According to the invention, therefore, the previous concept is ver¬ leave laterally (radial) to offset the two receiving spaces for the wassersteu¬ ernde valve and the switching device against each other. Instead, the "depth" of the installation niche of the building wall is used, in which direction generally enough space is available. The use of the "depth" happens because the two receiving spaces in the axial direction more or less in alignment, at least "behind" This has the consequence that the valve stem for the changeover device can no longer run in the axial direction in the above sense, but must be led out in the radial direction of the housing of the concealed fitting The consequence of this is that the actuating mechanism must be variably adjustable in accordance with the "installation depths" prevailing locally, that is to say the distances which exist between the house lines and the respective outer surface of the building wall.

In general, the UmsetzVorrichtung comprises a shuttle, which is by means of the valve stem between see two valve seats linearly movable back and forth. In this case, the flush-mounted faucet according to the invention Erin preferably designed so that the receiving space for the switching device extends radially and the valve stem of the switching device is movable in the radial direction.

A particularly comfortable embodiment of the invention is characterized in that the manual actuating member is movable in the radial direction. This type of movement is not only perceived by the user as particularly pleasant; It is also characterized by the fact that the manual operation process has the same distance from the covering rosette in both positions of the changeover device in the axial direction.

It is preferred if the manual actuating element is arranged on the edge of the covering rosette. Thus, the manual actuating organ protrudes over the covering rosette in the radial direction, which in turn allows particularly small dimensions of the covering rosette. When the manual actuating element slides at least with a region on the outer surface of the covering rosette, it is guided particularly well. Compressive forces applied by the user in the axial direction are absorbed by the covering rosette.

A particularly preferred actuating mechanism, the o. G. Meets requirements

a) a guide bracket which is guided linearly displaceable on the inside of Ab¬ deck rosette;

b) a coupling bracket, which is hingedly connected at one end region with the guide bracket and cooperates at the opposite end region with the valve stem of the changeover device.

This actuating mechanism bridges different "installation depths" in that the angle between the

Modified guide bracket and the coupling bracket.

An embodiment of the invention will be explained in more detail with reference to the drawing; show it

FIG. 5 is an isometric view, seen from below, of the covering rosette of the flush-mounted fitting of FIGS. 1 to 4 with the actuating device attached thereto for the change-over device;

Figure 6 is an isometric view, seen from above, a support plate which is part of the cover rosette of Figure 5.

Reference is first made to FIGS. 1, 5 and 6, with reference to which the construction of a sanitary flush-mounted fitting designated overall by the reference numeral 1 is described. In the present case, it is a single lever mixer; In principle, however, it could be any other type of sanitary flush-mounted mixer, in particular also a thermostatic mixer.

The concealed fitting 1 comprises a cup-shaped, upwardly open installation box 2 made of plastic, in the interior of which a Anschlußkör¬ per 3, an intermediate housing 4 with a Umstellvorrich¬ device and - partially - a cartridge housing 5 unter¬ brought from bottom to top. The connecting body 3, the intermediate housing 4 and the cartridge housing 5 can each be understood as parts of a fitting housing 40 of the flush-mounted fitting 1. to become. On the upper edge of the installation box 2 is a Abdeckrosette 6, which has a relatively large, central passage opening 7. Through the Durchgangs¬ opening 7, a region of the cartridge housing 5 extends through the outside, on the upper front side in a known manner, a spherical ring-shaped cover 8 is placed.

The connecting body 3 has four by 90 ° to each other angularly offset, radially piercing the mounting box 2 connecting piece, of which in Figure 1 three, namely the connecting pieces 9, 0 and 11, can be seen. The connecting piece 9 is connected in the installation of Unter¬ cleaning fitting 1 with the cold water house line; the diametrically opposite connecting piece 11 is connected to the hot water house line. At the Anschluß¬ nozzle 10 a leading to the tub water pipe and diametrically opposite, not shown connecting piece a leading to the shower water pipe is connected.

As indicated above, a Umstellvor¬ direction is housed in a receiving space 41 of the intermediate housing 4 (see Figure 2), with which the water flow optional to the connection piece 10, ie to the trough, or to the connection piece, not shown, so to the shower , can be directed.

The switching device is basically built in a known manner and therefore not shown in the drawing. It comprises a shuttle which can be moved back and forth between two positions in the receiving space 41 designed in the manner of a cylinder bore in the axial direction. In one position he closes a valve seat in the waterway leading to the shower, and in the other position, a valve seat in the waterway that communicates with the tub spout. A special feature of the switching device of the concealed fitting 1 is that the axis of the receiving space 41, in which the shuttle moves, extends radially.

The double-action valve cone, which is not shown in the drawing, is actuated by a valve stem 12, which projects out of the intermediate housing 4 in the radial direction and can be seen in FIG. The valve stem 12 carries at its outermost end an enlarged head 13th

The cartridge case 5 has a receiving space in which a conventional control cartridge is housed. The controlling element of this control cartridge, generally a movable ceramic disc, is actuated by means of a stomping 14 projecting from the upper opening of the cap 8. In the assembled state, a control lever, which overlaps the cover cap 8 with a cap-like section, is placed on the support 14 in a known manner. By turning and pivoting this operating lever, the temperature and the amount of effluent mixed water can be adjusted.

In order to actuate the Umstellvor¬ accommodated in the intermediate housing 4, the valve stem 12 must be moved in the radial direction. For this purpose, a Be¬ actuating device which carries the reference numeral 15 in total. As shown particularly in FIGS. 5 and 6, the actuating device 15 comprises an actuating mechanism with an approximately horseshoe-shaped guide bracket 16 which surrounds the through-opening 7 on one side and which is mounted in the manner described below on the underside of the covering rosette 6 parallel to this. slidably guided. At the outer ends of the legs of the guide bracket 16, the outer ends of the legs of a likewise approximately horseshoe-shaped coupling bracket 17 are articulated by means of pins 18. The base of the coupling bracket 17 has a passage opening 19, through which the outer end region of the valve stem 12 of the transfer device is guided. The head 13 of the valve stem 12 is slightly larger than the diameter of the through hole 19 of the coupling bracket 17, so that it can not slip through this passage opening 19.

Two legs of the two, the actuating mechanism forming bracket 16 and 17 are in their outer Endberei- chen by a tension spring 19 connected to each other.

The cover rosette 6 is composed of two parts, namely a support plate 6a, which is drawn out in its own way in FIG. 6, as well as a decorative cover 6b covering the support plate 6a and attached thereto.

The base of the guide bracket 16 is integrally connected to a slider 20 which is guided laterally by two guide profiles 21, 22 formed on the underside of the support plate 6a of the cover rosette 6. The slider 20 penetrates in the radial direction the provided in the edge region of the cover rosette 6 hollow cylindrical structures and projects radially beyond the outer edge of the covering rosette 6 over. Here is a serving as a manual operating knob 23 on the profiled accordingly

Slider 20 attached, which rests displaceably with a recognizable in Figure 1 area 23a on the top of Abdeckrosette 6 and also part of the Betätigungs¬ device 15 is. A spring 50 shown in FIG. 6, which is located in a section of the carrier plate 6a. placed and clamped between the slide 20 and the edge of the cut Aus¬ ^' seeks to pull the Betägigungsknopf 23 in the position shown in Figure 1, in which the water is passed from the changeover to the tub outlet.

The flush-mounted fitting 1 described above is mounted in a folklore in the following manner in accordance with local conditions:

The entire concealed fitting 1 is in the wall niche

1 introduced until the connecting pieces 9, 10, 11 and the connecting piece, not shown, aligned with the ent speaking terminals of the house lines and can be connected to them. Thus, the Einbau¬ position of the flush-mounted fitting 1 is fixed. Now it is determined how far the cup-shaped installation box

2 over the outer surface, for example, the tiling, the building wall protrudes and cut off the protruding area. Now, the support plate 6a Abdeckrosette

6 are placed on the upper edge of the mounting box 2 and secured by means of screws to the mounting box 2. Then, the decorative hood 6b is snapped onto the support plate 6a. The assembly process is completed by placing the operating handle on the control 14 of the control cartridge. The sanitary concealed fitting 1 is now ready for use.

Normally, the actuating knob 23 is in the position shown in Figure 1, in which the switching device within the Zwischengehäu¬ ses 4, the water to the tub outlet, ie to the forwardly facing in Figure 1 connecting piece 10 passes. This position is preferred due to the different springs. If the user is changing the water flow desires on the shower, he presses with his finger the actuating knob 23 radially outwards and moves the slider 20 and the associated Betätigungs¬ bracket 16 linearly along the underside of the Abdeckrosette 6 along. Also, the clutch bracket 17 makes this movement with.

2, in which the valve stem 12 of the Umstellvor- direction in the intermediate housing 4 is pulled out radially and the associated shuttle valve closes the valve seat, which leads to the tub, and on the other hand, the valve seat, which leads to the shower, opens. Due to the water pressure of the shuttle remains in a known manner in this position, even if the user

Finger from the operating knob 23 takes. Only when the water is turned off by means of the control cartridge, the pressure acting on the shuttle water pressure drops so far that under the action of the various springs, the shuttle is returned to the preferred position in which the tub is operated with water.

FIGS. 1 and 2 show a situation in which the house lines are laid relatively low below the wall surface. In this situation, the guide bracket 16 and the coupling bracket 17 enclose a relatively large angle. The cartridge housing 5 protrudes only slightly over the top of the covering rosette 6. The actuating knob 23 is located at the level of the covering rosette 6, its region 23a, as described above, resting on the upper side of the covering rosette 6.

FIGS. 3 and 4 show an installation situation. in which the house lines are laid verälntnismäßig close to the surface of the building wall. One speaks of a "small installation depth". The cylinder wall of the installation box 2, as can be seen from the figures, cut relatively far, so that the depth of the installation box 2 compared to Figures 1 and 2 is low. The guide bracket 16 and the coupling bracket 17 include a small, in the illustrated embodiment even negative angle with each other. The cartridge housing 5 protrudes relatively far beyond the Abdeckrosette 6. However, the control knob 23 is in the same relative position with respect to the covering rosette 6 as in the installation situation of FIGS. 1 and 2.

Due to the arrangement of the Umstellvorrichtung in Zwischen¬ housing 4 axially behind (in the drawing below) the cartridge housing 5 and before (in the drawing on) the terminal housing 3, the concealed fitting 1 described in the radial direction is relatively small. To this

It is also possible to keep the covering rosette 6 small in size, which is advantageous in terms of aesthetics. Regardless of different installation depths, the actuation of the changeover device always takes place in the same way by a radial movement of the corresponding actuation button 23.
