Description

[0001] The present invention relates to a mounting housing for sanitary fittings, such as washbasin or urinal fittings.

[0002] To facilitate the adjustment or maintenance of faucets installed in or behind a wall, it is very practical to use a mounting box with openings for water inlet and outlet, which are preferably sealed. This prevents water from penetrating the wall in the event of a leak in the faucet itself.

[0003] Such housings are described, for example, in the documents DE 10 2011 051 739 A1, CN 1 02 720 888 A, EP 2 143 846 A1, DE 10 2008 064 253 B3 and EP 1 382 757 A1.

[0004] These housings consist of a tubular, essentially cylindrical body, a flange that encircles this body and allows the housing to be attached to a wall, and a means for positioning and locking the flange to the tubular body. They have an opening at the front to drain unwanted water. However, they have the disadvantage of requiring the production of complex molds, and their application proves difficult or even impossible, particularly in the case of renovating older buildings.

[0005] One objective of the present invention is therefore to create a built-in housing that can be easily adapted to any situation.

[0006] Another objective of the invention is to create such a housing that allows for quick adjustments and whose components have shapes that are easy to produce by casting.

[0007] These objectives, as well as others that will become clear subsequently, are achieved by a mounting housing for sanitary fittings, such as washbasin or urinal fittings, which has a tubular body provided with a flat bottom and which has two diametrically opposed holes near this flat bottom and two foot-forming units that are detachably attached to this tubular body, wherein an adjustable collar is attached to this tubular body and wherein this mounting housing is characterized according to the invention in that the outside of the tubular body has two wedge-connecting grooves extending from the flat bottom and over a certain length for fastening each of the foot-forming units.

[0008] Preferably, the inside or outside of the tubular body is flat at the level of two holes.

[0009] Advantageously, the wedge connection grooves border on the sliding rails.

[0010] Preferably, the wedge-joint grooves lie in a plane perpendicular to the axis of the two holes.

[0011] Advantageously, the two units forming a foot have a shape such that the outer sides of each are inscribed in a rectangle and that the inner sides conform to the shape of the outer side of the tubular body, and the inner side of each unit forming a foot carries two ramps that interact with two inclined planes formed on the outer side of the tubular body and arranged on either side of the wedge-jointing grooves.

[0012] Preferably, each foot-forming unit is attached to the tubular body by means of fasteners in the form of bolts, which interact with the wedge-connecting grooves.

[0013] Advantageously, the outside of the tubular body also has longitudinal rows of teeth to accommodate the adjustable collar, which has projections with a snap-in profile opposite these teeth.

[0014] Preferably, a bean-shaped recess is formed in the collar above each snap-in profile to give elasticity to this snap-in connection.

[0015] Advantageously, the lower part of the collar has a radial slot and on either side of this slot a hole with a shoulder to accommodate a screw-nut unit to ensure a secure locking of the collar.

[0016] Advantageously, the rear side of the collar has a concave groove to accommodate a foam seal designed to conform to the front of a wall.

[0017] In a preferred embodiment of the present invention, the lower outer surface of the tubular body has a series of grooves with the profile of water droplets to prevent any escape of water into the wall as a result of a possible leak inside the housing.

[0018] Advantageously, the outside of the tubular body has at least one longitudinal rib in an upper or lateral area, which interacts with at least one recess formed in the collar and designed to block this collar against rotation.

[0019] The following description, which is in no way restrictive, must be read in consideration of the attached figures, among which: - Fig. 1 a perspective three-quarter front view from above of a built-in housing according to the invention is, - Fig. 2 a front view of the mounting housing of the Fig. 1 and - Fig. 3 A perspective three-quarter rear view from below of the installation housing of the Fig. 1.

[0020] As can be seen in these figures, a built-in housing according to the present invention has a tubular body 1, the inside of which 1a is cylindrical and which is provided with a flat bottom 2. The front of this flat bottom 2, i.e., the one facing the interior of the tubular body 1, is provided with fastening means 3 and 4 for receiving a tap.

[0021] The tubular body 1 is provided near the flat bottom 2 with two diametrically opposed holes 5 and 5': preferably the outside or the inside of this tubular body 1 is flat in this area.

[0022] According to the invention, the outer surface 6 of the tubular body 1 has two wedge-joint grooves 7 and 7', arranged on either side of the holes 5 and 5': These wedge-joint grooves extend from the flat base 2 over a certain length. In the present embodiment, these wedge-joint grooves are diametrically opposed to each other and lie in a plane substantially perpendicular to the plane of the axis of the holes 5 and 5'.

[0023] These wedge-jointing grooves 7 and 7' are each bounded by sliding rails 8 which extend substantially the same length as these wedge-jointing grooves.

[0024] The mounting housing also includes two foot-forming units 9 and 9', the outer surfaces of which are inscribed in a rectangle and whose inner surfaces are fastened to the tubular body 1 by fasteners, such as the bolts 10 and 10' respectively, which interact with the wedge-connecting grooves 7 and 7', and whose inner surfaces conform to the shape of the outer surface of the tubular body 1. Each unit 9 and 9' can therefore slide on the tubular body 1 along the guide rails 8, thus allowing easy adjustment of the mounting depth of the housing.

[0025] In a preferred embodiment of the present invention, the inside of each unit has two ramps 11 and 11' which interact with two inclined planes 12 and 12' respectively, which are arranged on either side of the wedge-jointing grooves 7 and 7'.

[0026] Each foot-forming unit 9 and 9' is pierced with two openings 13 and 14, each designed to receive a fastening screw. These openings have a countersink on the front and back, thus allowing the foot-forming units 9 and 9' to be fastened to a wall, regardless of whether they are mounted on the front or back.

[0027] In the present embodiment, the positions of the bolts 10 and 10' are offset from each other to allow the adjustment range of the installation depth to be increased by reversing the units 9 and 9' forming a foot.

[0028] The outer surface of the tubular body 1 also has longitudinal tooth rows 15 to accommodate an adjustable collar 16, which can slide onto them. In the present embodiment, there are four of these longitudinal tooth rows 15, diametrically opposed to each other. Opposite these tooth rows 15, the collar 16 has four rows of snap-in profiles 17. A bean-shaped recess 18 is formed in the collar 16 above each snap-in profile to give this snap-in connection elasticity and thereby facilitate the insertion of this collar 16.

[0029] The lower part of the collar 16 has a radial slot 19 with a hole having a shoulder on either side of this slot 19, which accommodates a screw-nut unit 20 to ensure a secure locking of the collar 16.

[0030] The rear side of the collar 16 has a concave groove 21 which accommodates a foam seal 22 designed to conform to the front of a wall and thereby prevent any risk of water penetrating the wall.

[0031] The outer surface 6 of the tubular body 1 has a series of grooves 23 with the profile of water droplets along a lower generatrices of the tubular body 1 in order to prevent any leakage of water into the wall as a result of a possible leak inside the housing.

[0032] In the present embodiment, the outer surface 6 of the tubular body 1 has at least one longitudinal rib 24 in the upper or side region, in this case three, which interacts with at least one recess, in this case three, which is formed in the collar and is intended to block this collar against rotation.

[0033] In a known manner, the tubular body 1 must be cut off by the installer immediately at the collar after the collar 16 has been adapted to the cladding of the wall; the collar 16 has notches for the attachment of a cladding plate which, in a known manner, carries the operating elements of the tap.

[0034] In the present embodiment, the tubular body 1 has essentially a cylindrical shape and a circular cross-section, but it could also essentially have the shape of a parallelepiped.
