Description

description

FIELD OF THE INVENTION The present invention relates to a built-in box, preferably as a semi-finished product, for (flush-mounted) installation in a niche or recess in a wall or pretext. In particular, the invention relates to a watertight installation box for sanitary facilities in wet rooms or in the kitchen.

Background of the Invention There is a great need on the market to provide wall niches for storing objects in wet rooms or in the kitchen instead of the usual wall-mounted brackets. This has the advantage that no objects protrude from the wall surfaces. Furthermore, neither fasteners such as e.g. Screws still necessary the necessary holes.

As a rule, such wall niches are sharpened for the storage of objects by a plasterer or tiler. Then the surfaces of the niches are mortar or the like balanced.

Then wall coverings (such as tiles) are laid in the interior or around the wall niche. Alternatively, a built-in box is made from different panels (such as plasterboard) manually and inserted into the prepared wall niche. The manual individual production of such boxes is very time consuming. Furthermore, the shape variability and precision of such built-in boxes that are individually hand-made on site are very limited and unpredictable.

In order to offer an ideal water drainage and a visually attractive solution, it is essential that the built-in box is installed flush with the wall niche.

In addition, more and more builders want the lighting of the built-in box.

Another difficulty / problem of these solutions arises from the fact that strict structural standards and regulations relating to watertightness must be hooked into wet rooms.

The water resistance was ensured according to the previously known solutions in that the interior of such wall niches / built-in boxes was sealed manually (mostly by the tiler). However, this work is very time-consuming and prone to errors. Especially in the area of corners and edges, it is very difficult to produce a properly processed seal that meets the requirements.

Technical problem to be solved Therefore, the technical problem to be solved by the invention is to provide an installation box with lighting which offers reduced installation times and guaranteed watertightness.

DISCLOSURE OF THE INVENTION The technical objects of the invention identified above are achieved by an installation box which forms a closed-surface cavity with an access opening on the room side. A recess is provided in the area of the cavity, which is designed to accommodate an illumination device. The lighting device sits in the recess and comprises fastening means which enable the height of the lighting device to be adjusted in relation to a surface of the cavity which surrounds the lighting device.

The cavity comprises two side walls, a bottom, a top surface and a rear wall, the cavity being designed as a closed surface by all walls, the bottom, the top surface and the rear wall of the installation box being closed in themselves and being connected to one another in a water-tight manner. The closed-surface cavity includes an access opening on the room side. In the area of the top surface, a recess is provided, which is designed to accommodate a lighting device. The lighting device sits in the recess and comprises fastening means which enable the height of the lighting device to be adjusted in relation to the top surface or to the level of the top surface.

Advantageous Effects The most important advantage of the invention is that a built-in box is available as a watertight semi-finished product, which can be installed in a time-saving manner, while compliance with strict building standards and regulations relating to watertightness can be guaranteed. The time-consuming and qualitatively unreliable sealing of the box interior is eliminated. Due to the height adjustment, an adjustment to the thickness of tiles or other cladding materials can be made on site during installation.

Another advantage of the invention lies in the flexibility of the height adjustability on site. This makes it possible to position the lighting device so that its lowest level (e.g. a diffusing lens or transparent cover plate) is flush with the tiles or other cladding materials that are used for cladding inside the box.

CH 711 422 B1 [0014] The box can therefore be coated or clad with materials of different thicknesses without any problems. The height adjustment of the lighting device enables a corresponding adjustment on site.

1A shows a perspective view of a preferred embodiment of the installation box 1 for wall-flush installation according to the present invention. As can be seen in the figures, the installation box I comprises a plurality of walls 11a, 11b, 12 (also called rear wall), a top surface 14 and a floor 16, which are self-contained and connected to one another in a water-tight manner. These walls 11a, 11b, 12 together with the top surface 14 and the floor 16 define an interior space 5. The interior space 5 is in each case through an opening 10 on the front side of the installation box 1

CH 711 422 B1 accessible. For the storage of objects, e.g. Shampoo bottles or the like, the interior 5 comprises at least one storage surface 20. The bottom 16 can be e.g. serve as a storage surface 20.

For installation flush with the wall, the installation box 1 can be provided with a flange 18 running around the opening 10. As can be seen in FIG. 1B, which represents a perspective cross section of the installation box 1 of FIG. 1A, the flange 18 runs essentially at right angles to the side walls 11a, 11b, 12 and / or to the bottom 16 and the top surface 14 of FIG Installation box 1. In order to enable a fixed installation, the flange 18 is preferably at least 1 cm wide (measured parallel to the installation wall).

In Fig. 1B it can be seen that a recess 30 is provided in the area of the top surface 14 for receiving a lighting device. The recess 30 is preferably surrounded by a conversion 31 in all embodiments. In all embodiments, such a conversion 31 can include side walls and a top surface, as indicated in FIG. 1B. The conversion 31 serves to close the area of the recess 30 tightly upwards and to the side.

2 shows a perspective rear view of a further installation box 1 of the invention. The same reference numerals are used as in connection with the other embodiments, even if the elements can differ in detail.

The installation box 1 of FIG. 2 in turn has a circumferential flange 18 and a box with surrounding walls 11a, 11b, 12, a bottom 16 and with a top surface 14. In the area of the top surface 14 there is a recess 30 for receiving a Lighting device provided. In the perspective rear view of FIG. 2, only the conversion 31 can be seen, which still tightly encloses the recess 30 at the top and to the side.

3A and 3B, further details of an embodiment according to the invention will now be described. 3A shows a side section through an installation box 1 of the invention, which is installed in a wall 2. A wall niche is provided in the wall 2 so that the installation box 1 can be installed in the wall 2 from the room side (on the right in FIG. 3A). The elements of the installation box 1 are shown in cross-section in white in FIGS. 3A and 3B. In this exemplary embodiment, the installation box in turn comprises a circumferential flange 18, a top surface 14, a rear wall 12 and a base. The two opposite side walls 11 a and 11 b are not shown.

A plaster 3 is provided on the front wall. The circumferential flange 18 is covered with a sealing tape 4 and covered or coated with a (liquid) seal 6. The (liquid) seal 6 can optionally also extend into the interior of the installation box 1. In FIG. 3A it can also be seen that a tile adhesive 7 follows on the room side. This tile adhesive 7 extends along the vertical wall surfaces and also along all inner surfaces of the installation box 1. The tile adhesive 7 serves to connect tiles 8 or another wall covering (e.g. mosaic stones or earthenware) to the wall 2 and the inner surfaces of the installation box 1.

From the thickness of the tiles 8 and the layer thickness of the tile adhesive 7, a different overall thickness can result depending on the installation situation. So that the installation position of the lighting device 40 can now be adjusted relative to the position of the top surface 14, fastening means 41 are provided which enable height adjustment.

The fastening means 41 preferably sit in all embodiments in the interior of the recess 30, or in the interior of the conversion 31st

In the embodiment of FIGS. 3A and 3B, a U-profile serves as a conversion 31. The U-profile is fastened tightly in the area of the top surface 14 and connected to the top surface 14, so that no water into the wall in this area either can penetrate. The U-profile has an elongated opening, which is rectangular in the example shown. The opening points downwards into the interior of the installation box 1.

Details can be seen in the enlarged detail of FIG. 3B, the U-profile, which serves as a conversion 31. The U-profile with its opening down into the interior of the installation box 1. The U-profile extends upwards through the cover surface 14 and protrudes a little into the wall 2 with its upper region.

In order to protect the conversion 31 against splashing water and / or condensed water, in all embodiments this can comprise a transparent cover or scattering lens 32, as shown in FIGS. 3A and 3B using an example. In the example shown, the cover or scattering lens 32 has the shape of a U-profile, the lateral legs of which are designed in such a way that they can be inserted into the opening of the enclosure 31 from below. In FIG. 3B it can be seen that the legs of the U-profile of the cover or scattering lens 32 can be provided with sealing lips 33 in order to ensure a tight connection to the lateral legs of the tag 31 when inserted into the opening of the tag 31. The sealing lips 33 are shown schematically in FIG. 3B.

The lighting device 40 preferably includes lamps 42 in all embodiments. Here, LED lamps (e.g. LED strips) are preferably used in all embodiments. 3A and 3B, only one LED is shown as illuminant 42.

The fastening means 41 allow height adjustment in all embodiments either of the illuminants 42 relative to the top surface 14 and / or the cover or lens 32, if it is present.

CH 711 422 B1 In the exemplary embodiment in FIGS. 3A and 3B, a threaded rod 43 is used, which carries the illuminants 42 on the lower side. This threaded rod 43 is seated in a nut 44 or in a threaded hole on the conversion 31.

This nut 44 or the threaded hole is preferably provided with sealing means (e.g. a sealing lip) so that no water can get into the wall 2 through the nut 44 or the threaded hole.

However, an area can be provided on the conversion 31 in all embodiments, which is sealed off from the wall 2. The area can be realized, for example, by a cylindrical sleeve or chamber which is tightly connected to the enclosure 31.

In the embodiment of FIGS. 3A and 3B, both the height position of the lamps 42 and the height position of the cover or lens 32 can be changed. The cover or scattering lens 32 can namely be pushed into the interior of the U-shaped enclosure 31 to different degrees depending on the overall thickness of the tile adhesive 7 and the tiles 8.

Details of a further embodiment according to the invention will now be described with reference to FIGS. 4A and 4E. 4A shows a section along the line BB, FIG. 4B shows a front view (on the room side) of an installation box I, FIG. 4G shows a plan view of the installation box 1, FIG. 4D shows a section along the line AA and FIG. 4E shows one Enlargement of section Z.

4G, the conversion 31 can be seen. The conversion 31 comprises two fastening means 41, the position of which can be seen in FIG. 4G. This variant of the fastening means 41 is accessible from above. 4E shows that each of these fastening means 41 comprises a screw 45 which is mounted in a spring 46. The lower end of the screw 45 is in a nut 47 which is firmly connected to the spring 46. The height of the nut 47 can be adjusted up and down by turning the screw 45 (e.g. using a screwdriver). With the nut 47 is e.g. The illuminant 42 connected, which can thus be adjusted by turning the screw 45 up and down.

In contrast to the embodiment of FIGS. 3A and 3B, here the conversion 31 sits above the cover surface 14. Only the two screws 45 protrude through holes into the interior of the box 1.

Details of a further embodiment according to the invention will now be described with reference to FIG. 5. 5 shows a section through a further installation box 1. The installation box comprises a flange 18, a top surface 14, a rear wall 12 and a floor 16. The two side walls 11 a and 11 b are not shown. A conversion 31 is provided in the area of the top surface 14, which is firmly connected to the top surface 14 here. Fastening means 41 are provided on the conversion 31. In this embodiment, the fastening means 41 comprise a screw 45, the threaded shaft of which is inserted in a nut 46 which is connected to the conversion 31. Here, sealing means are preferably provided in the area of the nut 46 or on the nut 46. The lower end of the threaded shaft is seated in a sleeve 47 so that the threaded shaft can rotate freely in the sleeve 47. The sleeve 47 is connected to the lighting device 40. The lighting device 40 here comprises a hollow profile 48, preferably an elongated U-profile 48, in the interior of which a number of LED lamps 49 (e.g. an LED strip) are arranged. The LED lamps 49 can e.g. be cast in a transparent resin 50.

After the height position of the lighting device 40 has been adjusted relative to the position of the top surface 14 by turning the screw 45, a tile adhesive 7 can be applied and tiles 8 can be attached, as indicated in FIG. 5. In order to be able to fill up a space between the U-profile 48 and the tile adhesive 7 or the tiles 8, e.g. a joint material 51 (e.g. silicone) can be introduced.

Instead of the mentioned nut 46, e.g. a cylindrical sleeve or a bolt with an internal thread are also used in all embodiments.

Details of a further embodiment according to the invention will now be described with reference to FIG. 6. The structure is similar to that in FIG. 5. Reference is therefore made to the description of FIG. 5.

In the area of the top surface 14, a conversion 31 is provided, which is firmly connected to the top surface 14 here. On the conversion 31, e.g. Fastening means 41 are provided at two points. These fastening means 41 comprise a cylindrical insert 52, which has an axial through hole. In the through hole there is a plastic element 53 (e.g. made of rubber), which is provided with tooth-shaped lips on one side. The plastic element 53 is shown here in black. A type of rack 56 is seated on the U-profile 48 of the lighting device 40 and extends through the plastic element 53. The rack 56 has teeth that e.g. are complementary to the tooth-shaped lips of the plastic element 53. The lighting device 40 can now be pushed up or down as required from below (i.e. from the inside of the box 1) by hand or with a tool. The tooth-shaped lips, together with the teeth of the rack 56, form a height-adjustable fastening means 41, which at the same time also exerts a sealing effect. After the suitable height position has been specified, a joint material 51 (e.g. silicone) can be inserted here again.

CH 711 422 B1 The fastening means 41 can also comprise another toothed rack, which e.g. can be snapped into different height positions using clips.

Details of a further embodiment according to the invention will now be described with reference to FIG. 7. The structure is similar to that in FIGS. 5 and 6. Reference is therefore made to the description of FIGS. 5 and 6.

Here, the box 1 has an elongated conversion 31, the side walls of which protrude somewhat into the interior of the box 1. The lighting device 40 also comprises a U-profile 48, in the interior of which lamps 49 are received and, if necessary, also cast in. The elongated conversion 31 defines an interior 54 in which the lighting device 40 can be moved up and down. In order to be able to determine a height position, e.g. on the outside of the U-profile 48 plastic lips 57 are provided, which clamp the U-profile 48 between the side walls of the enclosure 31. In addition, the plastic lips 57 exert a sealing effect.

Here, too, a joint material 51 (e.g. silicone) can optionally be introduced again, but this is not shown in FIG. 7.

Details of a further embodiment according to the invention will now be described with reference to FIG. 8. The structure is similar to that in FIGS. 5, 6 and 7. Reference is therefore made to the description of FIGS. 5, 6 and 7.

Here, the box 1 has an elongated conversion 31. The lighting device 40 also comprises here, for example, a U-profile 48, in the interior of which bulbs are received and, if necessary, cast in (the bulbs are not visible in the section shown). The elongated conversion 31 defines an interior 54 in which the lighting device 40 can be moved up and down. In order to be able to determine a height position, e.g. a combination of a screw 58, a spring 59 and a sleeve 60 with an internal thread is provided. By turning the screw 58 from the interior of the installation box 1, the U-profile 48 can be shifted up and down between the side walls of the enclosure 31. Optionally, the plastic lips 57 of the fig. 7 are used. In order to achieve a better seal, a sealing ring can optionally also be provided in the area of the interior 54 (e.g. on the sleeve 60).

The installation box 1 is preferably made of metal (sheet metal) or plastic (e.g. from deep-drawn plastic) in all embodiments. In all embodiments, the installation box 1 can also be made from a woven material (e.g. glass fiber with resin).

In all embodiments, the installation box 1 is preferably coated with a material that corresponds to the specific application, such as Ceramic, glass, wood, synthetic resin, or with a mineral coating.
