Description

Sanitary concealed fitting with a basic body.

The invention relates to a sanitary concealed fitting with a base body, which is connectable to at least one water-conducting inlet or outlet, and at least one functional component, which comprises at least one water channel, wherein the functional component is releasably fixed to the base body with a connection device such that the Inlet or outlet is connected to the water channel water leading.

Such concealed fittings are used where, during the construction phase, a sanitary connection with a base body is to be prepared, which is connected to the corresponding domestic water line (supply or discharge line). The functional component, for example a thermostat or a two-handle fitting, is attached later to the base body. In this way, the decision on the nature of the functional component can be made very late, since this must be installed only during interior work.

From EP 0790 448 Bl a sanitary concealed fitting of the type mentioned is known in which a basic body without functional component is connected to the existing in the wall opening installation lines of the house installation. After or during assembly, a winding block can be attached to the base body. be wise, with which the installation can be checked for leaks. Subsequently, after a possibly existing tiling is completed, the functional component is attached to the base body. Since the functional component must be mounted here in the installation direction of the front of the base body, the known sanitary concealed fitting has a relatively large installation depth. Such a concealed fitting can therefore often not be used with small wall thicknesses, in particular in the case of drywall walls or pre-wall systems.

Object of the present invention is to provide a sanitary concealed fitting of the type mentioned in such a way that it has a small installation depth.

This object is achieved in that the connection device viewed in the installation direction laterally engages the functional component, such that the functional component is connected by a movement parallel to the surface of the mounting wall with the connection device and detachable from this.

According to the invention, therefore, the connection device and the functional component are arranged side by side in the installation direction, so that a much smaller installation depth is required, as is the case in the known sanitary fittings, in which the base body and the functional component are arranged one behind the other in the installation direction. Due to their low installation depth The flush-mounted fitting according to the invention can also be used with relatively thin walls. The flush-mounted housing offers a stable, easily accessible receptacle for the functional component. The functional component is also easily accessible in the flush-mounted housing for maintenance purposes. The detachable connection device allows easy installation and removal of different functional components.

In an advantageous embodiment, the connection device may have a connecting piece for the water channel, which runs essentially parallel to the rear wall of the flush-mounted housing. The connection piece can simply be frictionally connected, in particular screwed or screwed, and sealed, with corresponding receptacles in the base body or in the functional component, thus forming a watertight universal connection between the (inner) water channel and the (outer) inlet and / or outlet. management. The course of the connecting piece parallel to the rear wall of the flush-mounted housing is very advantageous in view of a small installation depth.

In order to be able to connect the functional component to the base body in a simple and releasable manner, the connecting device can have at least one threaded pin which fixes the connecting sleeve in a form-fitting manner in a corresponding receptacle in the base body or in the functional component. Conveniently, the functional component may be a valve device with a valve housing or a flushing housing. With the flushing housing, the installation can be checked for leaks after assembly. It can then be removed again and replaced by the final functional component, in particular a valve.

With regard to a universal usability of the base body, a hot water line, a cold water line and / or a mixed water discharge line can be connected to the base body. In this way, all necessary connections for the common functional components are available.

The connection device can be fastened to the flush-mounted housing, in particular detachably from the outside. This has the great advantage that the existing domestic water pipes do not have to be threaded into the flush-mounted housing. In addition, because of the detachable attachment different connection devices and flush-mounted housing can be modularly combined.

In order to acoustically decouple the base body and the functional component, a sound decoupling device, in particular at least one rubber plate, can be arranged between the base body and the functional component. In this way, the transmission of operating noise of the functional component, such as a solenoid valve or an electric motor of an electrically operated valve, significantly reduced to the base body and thus to the installation lines.

FIGS. 1 and 2 show a first exemplary embodiment of a sanitary flush-mounted fitting provided overall with the reference numeral 10 with a base body 12 and a valve housing 14 of an electrically operated mixing fitting (not shown in the following). The base body 12 without valve housing 14 is shown in FIG.

The base body 12 has an elongated, cuboid, in the installation direction, in the direction perpendicular to the installation wall (arrow 16), flat flush-mounted housing 18, the front, in the figures 1.3 and 4 in front and in Figure 2 above, is open. In addition, the base body 12 comprises a connection device 20 with a cuboid connecting body 22 made of brass, which is mounted from the outside to a short in the figures 1 to 4 left side wall 18a of the flush-mounted housing 18.

On the rear wall 17 of the flush-mounted housing 18, two elongated plate-shaped mounting tabs 24 are fastened from the outside, preferably screwed, welded or glued, which project above and below the flush-mounted housing 18 on its long sides in FIGS. 1, 3 and 4. The projecting areas of the mounting tabs 24 each have two elongated holes 26 which run perpendicular to one another, ie parallel to the long edges of the long side walls of the flush-mounted housing 18 or perpendicular thereto. The slots 26 are used to hold mounting screws, not shown, with which the Base body 12 can be aligned and fixed in a wall opening.

On the inner surface of the lower side wall 18c in FIGS. 1, 3 and 4, a U-shaped guide frame 28, which is viewed in the installation direction 16, is fastened. Its legs extend along the lower portions of the left side wall 18a and the right side wall 18b opposite thereto, and are respectively fastened to their inner sides. The guide frame 28 projects beyond the edges of the lower long side wall 18c, the left side wall 18a and the right side wall 18b at the front of the flush-mounted housing 18. The guide frame 28 facilitates the assembly of a trough-shaped cover, not shown, for the flush-mounted housing 18. To fix the lid is provided on the guide frame 28, in Figures 1, 3 and 4, left, a receptacle 30 for a corresponding pin or screw on the lid.

The left side wall 18a adjacent to the connection body 22 has three connection openings 32 arranged at the corners of an imaginary triangle, one of which is shown in section in FIG. Through the connection openings 32 leads in each case a parallel to the long edges of the rear wall 17 of the flush-mounted housing 18 extending connecting piece 34. In Figure 2, one of the connecting piece 34 in section and in Figure 3, all three connecting pieces 34 are shown isometrically. One corner of the triangle, as can be seen in FIG Front side of the flush-mounted housing 18, so that viewed in installation direction 16 above and below the front of the flush-mounted housing 18 next connection piece 34 two areas of the open front of the flush-mounted housing 18 are freely accessible.

In these two freely accessible areas, the left side wall 18a has two continuous holes, hidden in FIGS. 1 to 4, for a respective hexagon socket screw 36 visible in particular in FIGS. 1 and 3.

On the inner surface of the left side wall 18a of the flush-mounted housing 18 which faces the valve housing 14, a rubber plate 38 is also fastened, preferably adhesively bonded. The rubber plate 38 serves for the sound decoupling of the base body 12 from the valve housing 14.

The right-hand side wall 18b of the flush-mounted housing 18 has, in the region of the upper side wall 18d, two identical through-holes 40, visible in FIG. 2, which are each closed by a cover stopper 42. In the area of the lower long side wall 18 c, a further through hole 44 is provided, to which two opposite screw holes 46 are assigned, which is visible only in FIGS. 1, 3 and 4. The connecting body 22 is detachably attached to the flush-mounted housing 18 via the two hexagon socket screws 36, which run through the above-described continuous holes through the left side wall 18a. The heads of the hexagon socket screws 36 are easily accessible in the interior of the flush-mounted housing 18. In the connecting body 22 corresponding threaded holes are provided, which are not visible in Figures 1 to 4.

From the left side wall 18a of the flush-mounted housing 18 adjacent the right end of the connector body 22 lead a the rear wall 17 of the flush-mounted housing 18 facing, visible in Figure 2 in section upper connecting channel 47 and a non-visible lower connection channel and a front of the flush-mounted housing 18th adjacent also not visible front connecting channel out. Each connecting channel, which is explained below in a representative manner with reference to the upper connecting channel 47 in FIG. 2, has a receiving area 49 in the form of a circular cylinder open towards the right end side of the connecting body 22, in which the respective connecting piece 34 is firmly inserted. The receiving region 49 extends coaxially to the connecting opening 32 in the left side wall 18a, ie parallel to the longer edges of the rear wall 17 of the flush-mounted housing 18th

Adjoining the receiving region 49 of the upper connecting channel 47 is a step. Following the stage leads approximately in extension of the receiving area 49, a connection area 48 for a hot water pipe, not shown, with a reduced cross-section straight ahead and opens in the flush housing 18 facing away from the end face of the connecting body 22. The lower connecting channel is constructed accordingly. In the local, not visible in Figures 1 to 4 connection area leads a cold water line, not shown.

The not visible in Figures 1 to 4 receiving portion of the front connecting channel opens into a vertical connecting portion 50 which has the shape of a continuous circular cylindrical bore which is perpendicular to the front connecting channel and perpendicular to the installation direction 16 from the upper side of the connecting body 22 to the extends lower side. In the vertical connection region 48, a mixing water outflow line, not shown, can be attached optionally from above or from below, which leads to a shower. The respective unused opening of the vertical connection region 50 is closed with a sealing plug (not shown).

The three connecting pieces 34 are identical and constructed as follows:

Each connecting piece 34 consists essentially of a rotationally symmetrical pipe section, which is slightly less than halfway with a local external thread in the corresponding, an internal thread having, receiving portion 49 of the connector body 22 is screwed.

The region of the connecting piece 34, which is inserted in the receiving region 49, has a circumferential annular groove 52 with a ring seal, which seals the connecting sleeve 34 against the receiving region 49; this is shown in FIG. 2 using the example of the upper connecting piece 34. At the end region facing away from the connector body 22, the connecting sleeve 34 has a further circumferential annular groove 54 with a further annular seal, which seals the connecting sleeve 34 in each case against a housing receptacle 56 in the valve housing 14; the housing receptacle 56 will be described in more detail below. The annular grooves 52 and 54 having regions of the connecting piece 34 have the same outer diameter.

The region of the connecting piece 34 facing away from the connecting body 22 has a collar 58 of larger diameter, which extends from the right-hand end face of the connecting body 22 to near the annular groove 54. In the collar 58, a circumferential Fixierkerbe 60 is introduced with V-shaped profile.

The inner diameter of the connection piece 34 is somewhat smaller in the region remote from the connection body 22 than in the region inserted in the reception region 49 of the connection body 22 and has an inner surface. winch up. As long as no valve housing 14 or another type of functional component is mounted on the base body 12, there is an end plug 62 is screwed with a corresponding external thread and hexagon, which closes the connection piece 34 and prevents the ingress of dirt; this is shown in FIG.

The connecting pieces 34, which are in communication with the cold water and the hot water line, communicate via the corresponding water channel 74 and illustrated water paths with a likewise not shown, accommodated in the valve housing 14 mixing valve, which is actuated by an electric motor 78. A first mixed water path leads from the outlet of the mixing valve via a first magnetic valve 64 in the valve housing 14 to the shower, a second water path via a second solenoid valve 66 to an outlet connection 70, which communicates with a bath outlet, not shown.

The connection body 22 facing side of the valve housing 14 has a, visible in Figures 1 and 2, plateau 72, which has the three housing receptacles 56. The inner contours and inner diameters of the housing receptacles 56 correspond to the outer contours or outer diameters of the connection stubs 34; This is visible only in Figure 2 in section. The housing receptacles 56 are each with one of the hot water pipe, the cold water pipe or the mixed water drain pipe corresponding inner water channel 74th connected, of which only the hot water pipe corresponding water channel 74 in Figure 2 is shown in section.

In which the upper connecting piece 34 and the lower connecting piece 34 corresponding housing receptacles 56 leads each one visible in Figures 1, 2 and 4 radial threaded hole 76, which is easily accessible from the open front of the flush-mounted housing 18.

In each threaded hole 76, a threaded pin 78 can be screwed with hexagon socket, whose located in the housing receptacle 56 end tapers. When the connection piece 34 is inserted, ie when the valve housing 14, as shown in FIGS. 1 and 2, is arranged laterally of the connection device 20 in the flush-mounted housing 18, the edge of the fixing notch 60 facing away from the connection body 22 is located in the extension of the axis of the threaded bore 76 When the threaded pin 78 is screwed in, its conical end initially engages on the flank of the fixing notch 60. The conical end interacts wedge-like with this flank, thus pulling the connecting housing 14 to the left in FIG. 2 and thus fixing the valve housing 14 to the base body 12.

The hot water pipe, the cold water pipe and the mixed water outflow pipe are connected wasserfüh ^¬ rend in this way with the respective water channels 74 in the Ventilge ^¬ housing 14 detachably. In FIG. 4, instead of the valve housing 14, the base body 12 from FIGS. 1 to 3 is connected to a flushing housing 80, which comprises a jack-off screw 82. The flushing housing 80 has three housing receptacles, which are concealed in FIG. 4, for the connecting sockets 34, which correspond to the housing receptacles 56 of the valve housing 14. The fixation of the flushing housing 80 on the base body 12 is analogous to that of the valve housing 14. The flushing housing 80 is not the subject of the invention. Its function is known in the further and is therefore not described in detail.

The installation of the sanitary concealed fitting 10 takes place as follows:

First, the hot water pipe, the cold water pipe and the mixed water drain pipe, which are already laid in the wall opening in a known manner, connected to the respective terminal portions 48 and 50 of the corresponding receiving portion 49 in the connector body 22. The connecting pieces 34 were already screwed into the receiving area 49 in advance.

Subsequently, the flush-mounted housing 18 is brought with its rear wall 17 ahead in the installation direction 16 in the wall opening, after which the connection piece 34 of the connection device 20 are guided through the corresponding connection openings 32 in the left side wall 18a of the flush-mounted housing 18 from the side the. Then the connecting body 22 is screwed with the hexagon socket screws 36 with the flush-mounted housing 18.

The flush-mounted housing 18 is then fastened with suitable screws via the mounting tabs 24 in the wall opening.

Thereafter, the flushing housing 80 is attached. This is pushed with the housing receptacles 56 on the connecting piece 34 for this purpose. Thereafter, the setscrews 78 are screwed into the threaded holes 76 and so the flushing housing 80 fixed to the base body 12.

With the flushing housing 80 is now flushed in a known manner, the water-bearing system to clean it, and then tested for leaks.

The purge housing 80 remains attached to the base body 12 to protect the installation until the final functional component is assembled. This may only happen with the completion of the interior work, if necessary only after completion of tiling.

To connect the final functional component, the flushing housing 80 is first removed after loosening the threaded pins 78. The valve housing 14 is then connected and fixed analogously to the above-described mounting of the flushing housing 80 with the base body 12. Finally, a not shown water spout, the ^■ shower, any cover elements, such as cover rosettes, and controls the sanitary fitting mounted.

FIG. 5 shows a second exemplary embodiment of a sanitary flush-mounted fitting 110. Those elements that are similar to those of the first, described in Figures 1 to 4 embodiment are denoted by the same reference numerals plus 100, so respecting their description to the comments on the first embodiment reference is made. In contrast to the first embodiment, in the second embodiment, the structure of the front, upper and lower connection channels 147 in the terminal body 122 are identical. The mixed water line leads here from the side into the connection body 122 and not from above or below as in the first embodiment. The connecting pieces are not shown in Figure 5; instead, the threaded holes 182 in the connector body 122 are visible here. In addition, the connection body is fastened here with three screws to the flush-mounted housing 118, instead of with only two screws.

Incidentally, the valve housing 114 is constructed somewhat differently, but this will not be explained further, as this is not the subject of the invention. FIG. 5 also shows a tile frame 184 and a bath inlet 186 in the form of a flat, upwardly open channel, as it is used by way of example.

In all embodiments described above a sanitary concealed fitting 10; 110, the following modifications are possible:

The invention is not limited to the use in showers and bath inlets. Rather, it can also be used for other types of sanitary concealed fittings, for example for washing or sink fittings.

Instead of the valve housing 14; 114 of the electrically operated mixing valve or the flushing housing 80 may also be a different type of functional component, such as a thermostat or a two-handle fitting, to the base body 12; 112 are connected.

The base body 12; 112, instead of the hot water pipe, the cold water pipe and the mixed water drain pipe can also be connected with only one or two or more than three, even different types of water supply or discharge lines. In particular, it can also be connected to two or more mixed water outflow lines leading to further showerheads.

The connection device 20; 120 may also have only one or more than two setscrews 78. It can For example, be provided for each connection piece 34, a threaded pin 78.

The connection device 20; 120 may instead of outside even within the flush-mounted housing 18; 118 may be arranged. It can also be inextricably linked to it.

Instead of the rubber plate 38, a different type of sound decoupling device, for example a spring unit, can also be used.

The connecting piece 34 may also extend obliquely to the rear wall 17. It is important that in another than the described course, the installation depth of the flush-mounted fitting 10; 110 is not significantly increased and easy installation is guaranteed.

The connection piece 34 can instead of the connection device 20; 120 also with the functional component 14, 80; 114 be firmly connected. In this case, the corresponding receptacles in the connection device 20; 120 provided.

The connection body 22; 122 may be made of a different material, such as plastic instead of brass.
