(54) Installation element for connection of sanitary fittings with Built-in supply pipes.

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a recessed element for connecting sanitary fittings with built-in supply pipelines, said recess having a connector for the supply pipelines and a perpendicularly disposed perpendicular thereto, and may be built into walls in such a manner that , by stitching.

From German publication specification No. 2,155,930, a built-in element of this kind is known. This element consists essentially of two pipe bending pieces to which cold and hot water supply pipelines can be connected. These pipe bending pieces must be fixed by means of a groove so that, after incorporation into the masonry, a mixing battery with its connecting plug can be inserted into the pipe bending protruding from the masonry pieces and secured.

A disadvantage of this design is the relatively large dimensions of the connector. In addition, the groove can easily be bent out of shape by the rough treatment on construction sites, so that the mixing battery can not later be pushed and secured in the pipe nozzles protruding from the masonry, and the installation must be done. Finally, the possibility of a return of mixed water, e.g. for a shower, in the embodiment according to the above-mentioned printing not feasible.

From the specification of U.S. Patent No. 3,728,746, a mounting element is known in which the connection between supply pipes and luminaire is obtained by means of a manifold. This manifold is formed of two metal or plastic sheets, at least one of which has contours suitable for forming water channels, and which are assembled, respectively, by soldering or by means of an adhesive. In said manifold, several projecting means are mounted, at least separated from one another a control element and a spout. For this system, for mounting luminaires, e.g. a mixer battery, operated with multiple wall holes and corresponding connecting means.

SUMMARY OF THE INVENTION It is an object of the invention to avoid the disadvantages of the prior art known elements of this kind and to provide a recessed element in which the luminaire can easily be slid, without regard to plug dimensions, and placed on the finished plaster wall, where this simple connector contains a plurality of connecting paths for connecting to the water supply lines, mixing battery and shower, and fixing agent for the mixing battery on the connector.

The above object is achieved according to the invention in that between the outlet piece and the mounting luminaire there is provided a cylindrical projection part corresponding to the outlet piece, provided with three water channels, and that the projection part and said water channels are adapted to a cylinder plug which can be formed in the luminaire. the three water channels when the fixture is plugged in and locked on the front part.

The peculiarities of the main claim in particular offer the advantage that mounting of a hot and cold water mixing battery can then be done in a very simple manner by simply inserting the battery over the protruding part and securing it with a pin screw.

The invention will now be explained in more detail with reference to the drawing, in which 1 to illustrate the basic idea of the invention, the individual parts, for example, show a bathtub mixer battery as a connection fixture in a perspective view, fig. 2 is a longitudinal sectional view of the built-in element with the fully assembled battery; FIG. 3 is a longitudinal sectional view of the built-in element with the fully assembled battery in line A-B in FIG. 2, FIG. 4 shows a section through the assembled parts along the line E-F of FIG. 2, and FIG. Figure 5 is a perspective view of a fully assembled bathtub mixer battery with built-in element and stand for shower.

Referring to FIG. 1, the integral element is denoted by 1. It has on each side the connecting studs 2 too cold and 3 - hidden in FIG. 1 - for hot water and preferably offset by 90 °, also two jacks 4 and 5 for return of mixed water, of which, depending on the location of the drain pipe, the upper or lower is closed with a stop. This avoids turning the connector to achieve the correct position. With internal supply of ribs, the built-in element; divided into 4 U2730 three channels, of which it connects to the studs 4 and 5 for return of mixed water to the central outlet opening 6, while the other two are connected to the studs 2 and 3 for cold and hot water conduit to the peripheral outlet. apertures 7 and 8. 9 are the separately constructed projection portion for routing the three water channels to the fixture. It has a central bore 10 through which it can be sealed in a sealing manner by means of the screwed-in hollow screw 11 which, using the flat gasket rings 12 cut after the three water channels, is screwed into the thread 13 · The two peripheral water channels are routed in the projection member 9 in locations displaced 180 ° relative to each other, outwardly in slots 14 and 15-15 are hidden in FIG.

1. On this projection part 9, the luminaire, in the example shown bathtub mixer 16, is optionally pushed, if possible, by placing a cover rose 17 in between, with a part 18, which is designed as a cylinder plug and is pulled by ice screwing of a pin screw 19 against the wedge surface 20 provided on the projection part 9, fixed to the wall and secured in place.

For a more detailed illustration of the individual parts, in particular the water supply in the pre-construction part 9 and in the cylinder plug part 18, the connecting element with the finished mounting bath mixer battery is shown in figures 2 - 4 in section, thereof in fig. 4 in section E-F. Hereby, an extra spacer 21 is drawn between the recessed element 1 and the projecting member 9. Such a - short or long - spacer may conveniently be used, if e.g. a greater distance from the vessel to the wall requires the spout of the battery to stand further out from the wall. The spacer has the same channels that match the outlet openings 6,7 and 8 of the connector. Of course, when using such a spacer, the central hole screw 21 must be extended by the length of the spacer and the thickness of two spacers 22, 12.

The exact design and location of the water channels in the cylinder connector 18 and the location of necessary O-ring gaskets are shown in the figures. The cylindrical part 18, which is formed as an extension piece for the luminaire 16 in molding, is sealed outwardly with the O-ring 23 and against the inner luminaire with the O-ring 24. It has two cavities 25 and 26 which are located at such a distance from each other internally. that they are covered by the slots 14 and 15 of the water channels in the construction part 9, which slots are separated from each other by the O-ring 27. From the cavities 25 and 26, the supply of hot and cold water over the connecting channels 28 and 29 takes place in the mixing battery 16 under the seats 30 , 31 for the non-drawn valve tops and thence into the mixing and distribution compartment 32 of the switching member 33. In the position of the switching member, see fig. 2, the mixing water flows directly into the vessel outlet 34. If, by the movement of the switching member, the closure drains upwards and opens to the shower outlet, the mixing water flows through the conduit channel 35 into the central bore 10 of the projection part 9 and then through the central hollow screw 11. in the mounting element 1 and the upper, open-standing connecting rod 5 - see fig. 2 for forwarding, for example, to a stand shower.

FIG. 5 again shows in perspective the use of the built-in element according to the invention finished on the wall, bathtub mixer battery 16 with the built-in return channel 36 - shown in dotted lines - for the mixing water for the stand shower 37.

It is clear that the recessed element can be used for connecting also other fittings in the sanitary area, e.g. kitchen and dishwasher batteries.
