Description

Sanitary concealed fitting

The invention relates to a sanitary concealed fitting with

a) a connection body which has at least one connection for a water line, in particular a cold water house line and / or a hot water domestic line, and at least one fastening element for fastening the connection body in an installation opening;

b) a functional unit, in particular with a sanitary valve, which has connection means for the water-proof connection with complementary connection means of the connection body;

c) a connecting device with which the functional unit can be detachably fastened to the connecting body.

In recent years, increasingly sanitary flush fittings are used, in which the client can delay his decision on what exact type sanitary concealed fitting he wishes to the last phase of the interior of a building. Firstly, only one universally usable connection body is installed in an installation opening of the building wall, for example a wall tile, which is connected to the water pipes laid in the wall of the building, in particular the cold water domestic pipe, the hot water domestic pipe and optionally mixed water pipes becomes. The wall nested in this way is then covered until the interior of the building is largely completed. Only then the cover of the wall niche is removed again. Now decides the builder, which special type of concealed fitting he wants, for example, a Einhe¬ belmischer, a thermostatic valve or the like. The manufacturer of the flush-mounted fitting supplies a whole set of functional units which are standardized in such a way that they can all be connected to the same connection body but contain different sanitary valves. The special, desired by the client functional unit is then connected to the connector body; finally brewing chen only the wall covering the covering Rosette and the controls to be attached

Since the depth of the wall recess and the depth, in which the house lines are laid in the wall, vary, the way in which the connection body is fixed in the wall-see must also be variable. In known sanitary Unterputzarmatu¬ Ren of the type mentioned above, the connection body is adjusted by fitting Hol¬ zunterlagen or similar brackets to the wall recess, in particular, the installation depth of the connection body is varied in the wall recess. However, the adaptation with such wooden documents to be provided on site takes up a relatively long time. The attachment of the connector body to Wandauf¬ builds, prewall systems or the like adapt to achieve an optimal installation depth is not possible in this way at all.

The object of the present invention is to design a flush-mounted fitting of the type mentioned at the outset in such a way that the connection body can be adapted to different assembly situations and can be installed quickly and technically in these in a simple manner.

This object is achieved in that the connection body has an adjustable fastening device, with which the connection body in the Ein¬ construction opening in different mounting depths can be fastened and comprises:

d) at least one fixing ring displaceable along the connecting body in the axial direction,

e) at least one locking means for locking the Befestϊgungsrings to the connector body.

According to the invention, therefore, a fastening device is provided with which the connection body can be installed in a different installation opening on site in a technically simple and precise manner. With this fastening device, the connecting body can be adapted to different constructions, for example conventional facing, pre-wall systems or wooden stud walls. The time-consuming and time-consuming consuming adaptation with often provisional means, such as Holzun¬ documents and similar mounts, is therefore not required. With the fastening device, the installation depth of the connection body in the installation opening can always be precisely adjusted without additional aids. Errors during installation in a prefabricated wall mounting, for example a wrong installation depth and / or an oblique installation of the connection body, can be corrected with the fastening device.

In an advantageous embodiment, the attachment ring has at least one radially inwardly projecting bayonet claw, and the attachment ring is axially displaceable along the connector body and rotatably disposed at least in a portion of the connector body, and the connector body has at least one arcuate Arretierungsnut for receiving the bayonet claw , A fastening ring with a bayonet claw is technically easy to produce and allows a reliable and stable connection to the connection body. By turning the mounting ring, wherein the bayonet claw is pushed into the respective locking groove, the mounting ring is stably locked.

So that the fastening ring can not rotate when displaced along the connection body, in a further advantageous embodiment the connection body has at least one guide element, in particular a guide groove, for the fastening ring.

Different mounting depths can be realized in a further advantageous embodiment in that a plurality of locking grooves are arranged one behind the other.

In order to be able to dispense with additional fastening means, for example special screws, in a further advantageous embodiment the fastening ring has the same fastening element as the connecting body.

A particularly advantageous embodiment provides that the fastening ring has at least two mutually complementary coupling means with which it with a second identical fixing ring can be coupled, so that in particular large installation depths can be realized by successively set of a variety of standardized Befe¬ stigungsringen.

Expediently, an advantageous embodiment provides that a first coupling means is a ring collar which revolves on one of the two end faces of the fastening ring, and a second coupling means is an annular groove which extends in the other end face and is complementary to the annular collar, so that the two fasteners tion rings are technically easy to plug together.

In order to allow a greater variation of the installation depth, a further advantageous embodiment provides that the rear side of the connection body has a further coupling means complementary to one of the coupling means, with which at least one of the attachment rings can be coupled to the rear side. In this way, the fastening rings can also be inserted from the back onto the connector body.

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

Connecting body, in which two fastening rings are put on each other;

FIG. 6 is a schematic plan view of one of the fastening rings shown in FIG.

FIG. 1 shows a first exemplary embodiment of a connection body provided in general with the reference numeral 1 for a concealed sanitary fitting for installation in a wall installation opening. A functional unit (not shown), for example a single-lever mixer, a thermostatic battery or a two-handle fitting, can be connected to the connection body 1 in a manner known per se and fastened with a conventional connection device (not shown).

The connecting body 1 essentially has the shape of a hollow cylinder, which is closed at the bottom on its rear side 2 in FIG. 1 and open at the top at the front region 3.

In the area of the rear side 2, four connecting pieces 4 are introduced radially into the connecting body 1. The connecting pieces 4 may be integral parts of the Anschluß¬ body 1, but also separately with this parts to be joined. The connection pieces 4 can be connected in a manner known per se to water pipes not laid in the wall and not shown.

In the interior of the connection body 1, as shown in the front view in FIG. 3, four connection openings 5 respectively assigned to the connection stubs 4 are provided. At these connection openings 5, the respective functional unit can be connected in a water-tight manner to the connection body 1 in a manner known per se.

In order to be able to fix the connection body 1 in the wall in an installation depth corresponding to a standard standard, the connection body 1 in FIG. 1 has below the connecting piece 4, a rear mounting collar 7, which is interrupted in each case in the region of the connecting piece 4.

The fastening collar 7 protrudes radially beyond the outer circumferential surface 8 of the connection body 1. In the fastening collar 7, four continuous collar fastening bores 9 are arranged as fastening elements in FIG. 4, in each case at the corners of an imaginary square. The axes of the collar mounting holes 9 are parallel to the imaginary axis of the connector body. 1

In the collar mounting holes 9 screws not shown can be used, with which the connecting body 1 in a conventional manner in the wall can be screwed bar

In the front region 3 of the connection body 1, a front attachment ring 10 is arranged in the direction of the axis of the connection body 1 in FIG. 1 upwardly and downwardly displaceably, with which the installation depth of the connection body 1 in the wall can be changed.

The front fastening ring 10 has identical to the collar mounting holes 9 in their shape and their arrangement in Figure 2 visible ring mounting holes 11. In order to achieve different installation depths, the connection body 1 can be attached optionally with the rear attachment collar 7 or with the front attachment ring 10 in the wall installation opening.

On the inner circumferential surface 12 of the front fastening ring 10, three bayonet-type claws 15 are integrally formed in the middle between its two end faces 13, 14, radially inwardly, as locking means (see FIG. 2).

The bayonet claws 15 form sections of an imaginary hollow cylinder, whose outer circumferential surface adjoins the inner circumferential surface 12 of the front fastening ring 10 and is fixedly connected to this or emerges integrally therefrom. The centers of the arches spanned by the bayonet claws 15 form the corners of an equilateral triangle arranged in a plane parallel to the end faces 13, 14 of the fastening ring 10. The arc length of the bayonet claws 15 each speaks a central angle of 30 °. The bayonet claws 15 are half as high in the axial direction as the front attachment ring 10. They are approximately half as wide in the radial direction as the attachment ring 10.

In the outer circumferential surface 8 of the front portion 3 of the connector body 1 are three to the bayonet claws 15 complementary guide grooves 16 provided as a guide means for the front mounting ring 10, in the axial direction from the outer end of the front portion 3 of the connector body 1 to an area above the connecting piece. 4 run. The guide grooves 16 extend over a somewhat larger arc length than the bayonet claws 15. The depths of the guide grooves 16 are slightly larger than the widths of the bayonet claws 15. When the front fastening ring 10 is displaced along the front region 3, it becomes axial to the connection body 1 the bayonet claws 15 are guided in the guide grooves 16.

In the area in FIG. 1, directly above the connecting piece 4, three complementary locking grooves 17 of identical dimensions are annularly formed in the outer circumferential surface 8 of the connecting body 1 - the front locking groove 17 is covered by the front fastening ring 10 in FIG. The depth of the Arretie¬ rungsnuten 17 in the radial direction is slightly larger than the width of the bayonet claws 15, their width in the axial direction is slightly greater than the height of the bayonet claws 15, so that the bayonet claws 15 fit fit into the locking grooves 17.

The bayonet claws 15 can be pushed by a rotation of the front mounting ring 10 relative to the connector body 1 in the locking grooves 17 to prevent displacement of the front mounting ring 10 in the direction of the axis of the Anschluß¬ body 1 and to lock the front mounting ring 10.

The distance between two adjacent locking grooves 17 corresponds to half the height of the fastening ring 10, so that at the same time two fastening rings 10 can be locked hinter¬ each other on the front portion 3 of the connector body 1.

In addition, a plurality of recessed grips 20 are provided along the outer lateral surfaces of the mounting ring 10 at regular intervals, with which the Fixing ring 10 are easily rotated by hand. Otherwise, the fastening ring 10 has essentially the same geometry as the rear fastening collar 7.

In order to set the mounting depth in the niche during assembly of the connection body 1, a fastening ring 10 is pushed along the guide groove 16 on the connection body 1 from the front area 3 of the connection body 1 and fixed by turning into the corresponding locking groove 17.

Subsequently, the fastening ring 10 and thus the connector body 1 is fastened by screws, not shown, through the ring mounting holes 11 in a conventional manner in the wall.

FIG. 5 shows a second exemplary embodiment of the invention. It differs from the first exemplary embodiment only in that instead of the fastening ring 10 in the second exemplary embodiment two identical fastening rings 110 are placed on one another.

The fastening rings 110 in the second exemplary embodiment differ from the fastening ring 10 in the first exemplary embodiment only in that they each have a peripheral annular collar 127 shown in plan view in FIG. 5 on their upper annular end surfaces 113, which are shown in plan view in FIG. which correspond to the ring fastening bores 11 in the first embodiment, is in each case interrupted, and which serves as a first coupling means for coupling two fastening rings 110.

The annular collar 127 has the shape of a hollow cylinder which is placed in the middle between the inner circumferential surface of the fixing ring 110 and an outer circumferential surface on the upper end face 113 and fixedly connected thereto or integrally formed thereon.

In its lower end face 114, in the fastening ring 110, a peripheral annular groove 128 complementary to the annular collar 127 acts as the second coupling means arranged, in which the annular collar 127 of Figure 5 lower mounting ring 110 of the mounting ring pair 110 is inserted.

In addition, in a rear attachment collar 7 substantially similar to the rear attachment collar 7 in the first exemplary embodiment, a rearward engagement collar 107 on the rear side 102 of the attachment body 101 is likewise provided with an annular groove 129 complementary to the annular collar 128 of the attachment ring 110, so that, not shown in the figure, at least one of the fastening rings 110 can be plugged onto the rear fastening collar 107. The circumferential annular groove 129 is interrupted by four collar mounting holes 109 corresponding to the collar mounting holes 9.

By attaching or plugging together one or more fastening rings 110, the distance between a front, in Figure 5 upper Befestigungsi¬ tion possibility, namely the upper mounting ring 110, and a rear Be¬ fastening option, in Figure 5 the mounting collar 7 or at least one not shown, there plugged further attachment ring 110 ver¬ be enlarged, whereby a greater variation of the mounting depth is made possible.

Instead of the mounting holes 9, 11; 109, 111 can also eyelets or tabs, also in a different number, be provided with which the connection body 1; 101 or the fastening rings 10, 110 in the wall - Einbauöfmung or the like can be fastened.

The fastening rings 10, 110 may also be locked in a different manner, for example with bolts, instead of with a bayonet closure. It can also be provided more or less than three bayonet claws.

For example, it is also possible to provide a pin-hole pair or the like instead of the annular collar 127 and the annular grooves 128 with which two fastening rings 110 can be connected to one another. The connection body 1; 101 can be installed in a conventional masonry, a Vorwandsy- system, a wooden stand wall, a floor niche, a prefabricated house installation system or another type of wall installation.
