Description

The present invention relates to an installation system for sanitary fittings, including a built-in box for connecting sanitary fittings to water lines, which has a perimeter extending around the perimeter, restricting the installation opening from the front side of the built-in box and having a side wall having a height and a socket holder for subsequent overlapping of the installation opening, the installation system comprising a completely closing installation opening of the built-in box and having an installation cover extending along the perimeter parallel to the side wall.

An installation system with the features first mentioned is known from AT 399183 B. During the installation of such boxes as also known as hidden boxes, built-in boxes with a side wall, the main part initially, as a rule, protrudes above the unfinished wall. After the wall is finished directly to the side wall of the main part, the side wall of the main part is separated at the level of the finished wall surface. This separation must be performed with great accuracy, since the remaining side wall should not protrude significantly from the wall surface, nor should it be cut too deep, as the built-in box should also provide the wall with protection against condensation moisture occurring in the built-in box.

After cutting off the side wall and installing the sanitary fittings in the built-in box, the lid-shaped outlet holder is mounted on the built-in box above the protruding, in certain cases, sanitary fittings from the built-in box. In this case, the outlet holder with a relatively short wall section enters the built-in box and from the inside comes in with a seal in contact with the side wall. In this case, the seal occurs directly under the installation opening formed by the cut-off side wall.

The publication DE 102012203393 A1, which reveals the built-in box of the installation system, proposes, for ease of installation, that a cylindrical collar be installed on the side wall of the main part at different heights, with the cuff being pulled out of the main part as far as possible during wall decoration and, after finishing the wall, is pulled into the main part until until the installation opening formed by the cuff is flush with the surface of the wall. With this form of implementation of the built-in box, the disadvantage is, on the one hand, that during cuffing, despite fixing, the cuff can be moved inadvertently, and, on the other hand, that the cuff should be aligned in the plane of the finished wall surface, and it is not guaranteed that when installing the outlet holder, the cuff will remain in the required position. In addition to this, it is possible that due to contamination due to plastering or tiling, the cuff will be tight during alignment.

Therefore, the objective of the present invention is to take into account the state of the art to solve the problems that have been discovered and, first of all, to name the installation system, through which the installation of sanitary fittings in the wall is simplified. First of all, the installation of the outlet holder should be simplified without cutting the side wall of the built-in box and without the need to align another element.

This problem is solved by means of an installation system with features of an independent claim. Preferred improvements to the installation system are indicated in the dependent claims and in the description, and individual features of the improvements are arbitrarily combined with each other in a technologically expedient manner.

This problem is solved, first of all, by means of an installation system with the features mentioned at the beginning, and in the mounting position that overlaps the installation opening, the mounting cover acts as a protective edge section above the installation opening, so that when mounting an embedded box in the wall, the wall can be made up to the protective section of the mounting cover moreover, before installing the sanitary fittings, the mounting cover for releasing the installation opening is removable from the built-in box, and after removing the mounting cover, the socket holder with the help of a sealant is brought into contact with the side wall of the built-in box at a distance specified by the installation depth of the built-in box to the installation opening, and moreover, the outlet holder passing along the perimeter of the wall section covers the wall edge released by the removed mounting cover, passing along the perimeter between the wall surface and the installation opening.

First of all, it is envisaged that during installation, a built-in box with an installation opening already fixed to the wall is located inside the wall to be trimmed, and that the mounting cover protrudes axially above the wall to be trimmed. Thus, the wall can first be finished, for example, plastered or tiled, up to the protective section of the mounting cover. During wall decoration, the built-in box is protected from the ingress of dirt by the fully closed mounting cover. That is, there are no openings in the mounting cover through which dirt can enter the built-in box in the mounting position. After finishing the wall, the mounting cover is removed so that the installation opening becomes accessible. At the same time, the installation aperture that is not changed subsequently lies in the plane of the finished wall inside it. After the sanitary fittings are installed through the installation opening into the built-in box, the socket holder with the wall section is inserted into the built-in box, first of all, the protruding edge region of the socket holder fits into the finished wall surface and, First of all, between the protruding edge region and the surface of the wall is located a perimeter seal. The socket holder preferably has openings through which the sanitary fittings protrude through the socket holder. This ensures that the built-in box is protected from contamination during its installation, and after installation, the side wall of the built-in box does not need to be cut or aligned, since the wall section of the socket holder has such an axial length that it can be sealed in the built-in box at different depths.

The built-in box is, for example, a hidden box with a water distributor housing pre-installed in it for connecting water lines and sanitary fittings. The side wall can be made integral with the main part of the embedded box, but can also be an independent structural element of the embedded box. The leading edge of the side wall is limited by the installation opening.

The perimeter edge of the mounting cover has a cross-sectional shape corresponding to the cross-sectional shape of the side wall with a slightly larger or smaller diameter, so that the edge of the mounting cover can be bent over the side wall or inserted into the side wall. Preferably, the edge of the mounting cover, when removed, is in contact with the side wall of the built-in box.

The height of the protective portion of the mounting cover protruding above the installation opening is preferably at least half the height of the side wall of the built-in box. First of all, the length of the side wall in the axial direction is taken as the height of the side wall, along which the side wall has a constant cross section emanating from the installation opening. In this region defining the height of the side wall, the mounting cover and / or socket holder are movable along the side wall. The height of the protective portion of the edge of the mounting cover is the length of the mounting cover in the axial direction, with which the mounting cover protrudes above the installation opening in the mounting position, the protective portion of the edge having substantially the same diameter as the installation opening. The diameter of the outer perimeter of the protective portion of the mounting cover differs from the diameter of the outer perimeter of the side wall of the built-in box, primarily by a maximum of 5%, preferably a maximum of 3%. Since the height of the protective section is preferably at least half the height of the side wall, the mounting cover protrudes a considerable length on the installation opening, so that the protective section of the mounting cover extends from the installation opening in the wall to the surface of the wall to be finished. The height of the protective portion is preferably at least three quarters of the height of the side wall. It may also be provided that the height of the protective portion is greater than the height of the side wall. In addition to this, the height of the side wall ensures that the socket of the outlet inserted later in the built-in box can be sealed at different heights of the side wall. The height of the side wall is preferably at least 2 cm (centimeters), and particularly preferably at least 3 cm. How far the wall portion of the outlet holder protrudes into the side wall of the built-in box depends essentially on the installation depth of the built-in box in the wall .

The installation depth of the built-in box is the distance from the built-in box to the wall surface. The deeper the built-in box is fixed to the wall, the less deep the socket holder penetrates with the wall section extending around the perimeter into the side wall of the built-in box. Thus, protruding in the installed position above the installation opening of the wall section of the socket holder closes, first of all, that area of the wall that was previously made up to the protective section of the edge of the mounting cover. That is, the wall portion of the outlet holder has a height that is greater than the height of the protective portion of the mounting cover.

Preferably, the mounting cover is mounted on the built-in box by means of a screw which is protected against axial relative movement relative to the mounting cover of the screw, so that for removal the mounting cover is movable by the screw relative to the built-in box in the axial direction. The screw is protected from relative movement relative to the mounting cover, especially in the cup-shaped area extending back from the front wall of the mounting cover, so that a relatively short screw can be used to engage the built-in box. By actuating the screw, a breaking force can be provided by which the mounting cover, for example, can be released from the plastering brought up to the protective portion and thus additionally fixing the mounting cover.

Alternatively or additionally, it can be provided that the mounting cover is mounted on the built-in box by means of a press fit and has at least one tear-off formation also performed independently of the press fit along which the mounting cover is destructible before being removed. For example, a tear-off made in the form of a predetermined tear-off point can lie along the front wall, along the edge and / or along the cup-side region of the mounting cover, so that the mounting cover can be partially destroyed at first and subsequently be pressed in the radial direction inside, due to which you can simply free yourself from additional fixation due to plastering. Due to the tear-off formation from the mounting cover, the tape-shaped region is removed, first of all.

In order to prevent the fixing of the mounting cover due to the plaster or the adhesive for the tiles first, it can be provided that there is an axially extending annular tear-off element at least on the protective portion of the mounting cover. During the decoration of the wall, for example, a tear-off element made of fabric is stretched over the protective section and, if necessary, on the side walls, so that after the finish of the wall, the mounting cover allows the tear-off element to be reliably secured with plaster or adhesive for facing tiles to be installed boxes.

In order to prevent water from entering the brickwork, it can be provided that a sealing lip passing around the perimeter is removably located outside the protective portion of the mounting cover, which is connected to the sealing non-woven material extending radially from the mounting cover. A frame can be provided, for example, which has a sealing lip on its inside and is coated with a sealing non-woven material. The frame is made, first of all, with an opening for the mounting cover, and the sealing lip is aligned with the opening. After plastering the wall, the sealing lip and sealing non-woven material are pushed onto the protective area of the mounting cover, and the sealing non-woven material comes into contact with the plaster layer and, first of all, is then embedded into the adhesive for the tile. Then, a facing tile is glued onto the plaster layer and in the area of the sealing non-woven material onto the sealing non-woven material. Due to this, the sealing non-woven material is fixed between the tiles and the layer of plaster. When the wall is completely finished, the mounting cover is removed, and the sealing non-woven material fixed by the facing tile holds the frame with the sealing lip in its intended place. Then, the outlet holder with the wall section is guided through the sealing lip passing along the perimeter, and the sealing lip comes to fit against the wall section of the socket holder. Thus, by means of a sealing lip and a sealing non-woven material, water penetrating into the brickwork is prevented from penetrating through the seams between the tiles, despite the sealing between the edge region of the socket holder and the wall surface.

The sealing device described previously with a sealing lip and sealing non-woven material can also be used with conventional built-in boxes, regardless of the combination of a mounting cover with a socket holder according to the invention, and before laying the tiles, the sealing device would be extended along the side wall mounted in the wall of the built-in box .

In the following, the invention, as well as the technical environment, are explained using the figures, with the figures showing preferred embodiments of the invention. Schematically shown in:

FIG. 1 built-in box in cross section during wall decoration,

FIG. 2 perspective view of the mounting cover and

FIG. 3 is a cross-sectional view of the built-in box after installing the outlet holder.

In FIG. 1 shows an embeddable box 1 with a main part 2 and a side wall 4 fixed thereon, which defines an opening aperture 3 with its upper edge. The side wall 4 has a height of 5, along which a mounting cover 6 can be inserted into the mounting box 1. Mounting cover 6 has a passage along the perimeter there is an edge 7, which protrudes above the bounded side wall 4 of the installation opening 3. The protective section 8 has a height of 9. In addition to this, in the built-in box 1 there is a housing 24 of a water distributor for connecting water lines and sanitary fittings.

In the area of the bend that extends backward in the form of a bowl, the mounting cover 6 is fixed on the main part 2 with a screw 11. The screw 11 is not movable relative to the mounting bracket 6 in the axial direction.

The built-in box 1 is installed in the opening of the wall 10, and the wall 10 consists of brickwork 20 and a layer of plaster 21 made on it. The built-in box 1 with the installation opening 3 is located inside the opening in the wall 10 and protrudes from the opening by the protective section 8 of the mounting cover 6. Thus Thus, the wall 10 can be finished up to the protective section 8 of the mounting cover 6, made with a layer of plaster 21 or a later applied layer of facing tile.

In the depicted exemplary embodiment, a frame 25 with a sealing lip 13 located inside the seal portion 8 adjacent to the protective portion 8 is drawn through the protective section 8 of the mounting cover 6. On the radial outer side, the sealing non-woven material 14 is made 14. On the plaster layer 21 and, therefore, also on the sealing nonwoven fabric 14 is glued as shown in FIG. 3 facing tile 22, so that the frame 25 and the sealing lip 13 are fixed in their position.

When the wall 10 is finished, the mounting cover 6, by actuating the screw 11, moves axially relative to the built-in box 1. The force provided through the screw 11 is intended, first of all, to remove from the protective section 8 up to the protective section 8 and additionally fixing the mounting cover 6 layer of plaster. The mounting cover 6 evenly moves by moving with the screw 11.

Alternatively or additionally, the mounting cover 6 may have tear-off shapes 12 along which the mounting cover 6 is destructible. Such tear-off shapes 12, for example in the form of material weakenings, are shown in FIG. 12. Tear-off shaping 12 can be performed so that from the mounting cover 6 is a removable tape-shaped section. Subsequently, the mounting cover 6 can simply be compressed so that it can be released from the layer of plaster 21.

After the mounting cover 6 is removed from the built-in box 1, a socket holder 15 with a perimeter wall section 18 can be inserted into the built-in box 1. The corresponding mounting situation is shown in FIG. 3. It can be seen that the facing tile 22 fixed the sealing non-woven material 14 between the tile 22 and the layer of plaster 21. The socket holder 15 is directed by its wall section 18 through the frame 25, and the sealing lip 13 is adjacent to the wall portion 18 of the socket holder 15 from the outside, so a water barrier is formed for penetrating in certain cases through the seams between the facing tiles of water.

A seal 17 is located between the outer side of the wall portion 18 of the socket holder 15 and the side wall 4 of the built-in box. The distance 16 of the socket holder 15 protrudes the wall section 18 into the built-in box 1 depends on the installation depth 23 relative to the wall surface 19 the built-in box 1 is located. In this regard, it is provided that the socket holder 15 can be located with a seal in the main part 2 of the built-in box 1 at a different distance 16 relative to the installation opening 3).
