EP3366852B1 - Device for floor drain in the floor of a room - Google Patents

Description

The present invention relates to a device for a floor drain arranged in the floor of a room, in particular at a distance from a wall, according to the preamble of claim 1.

Floor drains of this type are generally used in floor-level showers, with channel-shaped drain bodies often being used. To date, to create a floor-level shower, it has been necessary for a shower tray or shower board to be equipped with a multi-sided slope towards the drain. The same applies to training with sloping screed. In the case of a drain in the middle of the shower area, a so-called central drain, four sloping areas are usually formed. If the drain is close to the wall, either three or four slope areas are worked out. If there are three slope areas, the first area is on the side opposite the wall. The two other areas are arranged in the longitudinal direction of the channel-shaped drain body to the left and right of this. Occasionally there is also a short, fourth slope area between the channel body and the wall.

It proves to be problematic that the formation of several sloping areas in the screed or in a shower tray causes a high level of manual or mechanical effort. In addition, the adjustment of the tile level to the different slope situations is demanding.

A device of the type mentioned is from DE 10 2014 111 784 A1 known. The device described therein has in particular a one-piece part made of stainless steel on which Surface a multi-slope contour is formed. The manufacture of such a device is comparatively expensive. Furthermore, no subsequent adaptation to local conditions or to design requirements can be made.

From the DE 10 2008 050 094 A1 a drain device with a channel-shaped drain body is known in which an elongated cover is arranged. The water to be discharged can enter the channel-shaped drain body around the cover.

From the U.S. 3,037,631 a drain device with a rotationally symmetrical drain body is known in which a sieve is introduced.

From the DE 20 2012 011 346 U1 a drain device designed as a shower tray is known. The shower tray has a recess into which an inclined cover is made, around which the water to be discharged can enter a drain body arranged below the shower tray.

The problem on which the present invention is based is to create a device of the type mentioned at the outset, which can be adapted more variably to local conditions or to design requirements, and in particular the manufacture of the device should be less expensive.

This is achieved by a device of the type mentioned at the beginning with the characterizing features of claim 1. The subclaims relate to preferred embodiments of the invention.

According to claim 1 it is provided that the device comprises a molded part and a receptacle, from which the molded part is received at least in sections, wherein on the molded part the im installed state of the device opposite to the horizontal inclined upper surfaces are arranged or formed, wherein the molded part and the receptacle each include an opening for the passage of water into the floor drain arranged below the device, the receptacle is open at the top when the device is installed and a base as well as a frame protruding upwards from the base and encircling the base, which surrounds the molded part and, in particular at the end, is adapted to the contour of the molded part, the opening of the receptacle in the base being excluded, and wherein the The molded part and the receptacle are elongated in a longitudinal direction and are significantly more extensive in this longitudinal direction than in the transverse direction perpendicular thereto. Due to the separate design of the receptacle and the molded part, the device can be designed in a more variable manner. Due to the upwardly open receptacle, the molded part can be easily inserted into the receptacle during assembly, with the surrounding frame still ensuring that the molded part is held in a stable manner.

It can be provided that, when the device is installed, the molded part can be introduced into the receptacle and, in particular, can also be removed from it, so that the molded part can preferably be removed for cleaning purposes. The insertability of the molded part also enables the design of the device to be more easily adapted to local requirements, in particular if the molded part is the only or at least predominantly visible part in the installed state. As the molded part can be removed, the device is easier to clean. Furthermore, the appearance of the device can also be changed subsequently by exchanging the molded part.

Alternatively, after being inserted into the receptacle, the molded part can also be firmly connected to the receptacle, for example by gluing.

It can be provided that the device is set up so that the molded part is converted into the final contour on site, the molded part being created by pouring a liquid or foam-like material into the receptacle during assembly.

There is the possibility that the molded part consists of a plastic, in particular a hard plastic or silicone or a foam-like material, or a metal, in particular stainless steel, or a plastic, in particular a hard plastic or silicone or a foam-like material, or comprises a metal, in particular stainless steel. In particular, a molded part made of silicone offers the feet of a user a non-slip contact surface. For example, the material of the molded part can also be colored, so that a large number of different designs result from the introduction or exchange of corresponding molded parts.

It can be provided that the receptacle is made of a plastic or a metal, in particular stainless steel, or comprises a plastic or a metal, in particular stainless steel. The receptacle can be adapted to the material of the molded part with regard to the material used. But there is also the possibility of creating a conscious contrast, for example by using stainless steel for the recording, the frame of which is visibly surrounded by a molded part made of colored silicone.

It can be provided that the device comprises a support part which is arranged between the molded part and the receptacle, in particular above the opening in the receptacle.

Despite its possibly small dimensions in the transverse direction, the device according to the invention can effectively reduce the work or production effort for the screed or a shower tray.

There is the possibility that the inclined upper surfaces in the position of use have a gradient to the horizontal in the first and / or in the second direction, at least one of the inclined upper surfaces being in particular designed as a free-form surface. The several different slopes formed in the prior art in the screed or in a shower tray or a shower board can thus be formed at least to a large extent on the device according to the invention.

It can be provided that the device comprises a cover which partially covers the opening of the molded part. It can be provided that the cover has at least one drain opening or that the cover is surrounded by a circumferential gap which opens into the opening. The circumferential gap or the, for example, slot-shaped drainage opening can be designed so narrow that they are barely visible to the viewer.

There is the possibility that the cover is made of a plastic, in particular a hard plastic or silicone, or a metal, in particular stainless steel, or comprises a plastic, in particular a hard plastic or silicone, or a metal, in particular stainless steel. The cover can consist of the same material as the molded part. However, there is also the possibility that the cover is made of a different material than the molded part, so that, for example, the molded part is made of silicone and the cover is made of stainless steel.

It can be provided that the device is more extensive in a first direction than in a second and a third direction, that is to say to the first direction and are perpendicular to one another, the first and the second direction in the installed state Device are arranged in the horizontal and the third direction corresponds to the vertical. Furthermore, it can be provided that the opening for the passage of water into the floor drain is more extensive in the first direction than in the second and third directions. In addition, it can be provided that the device and / or the opening are so slightly expanded in the third direction that the opening is not intended to accommodate parts of the floor drain.

The invention offers the craftsman and the shower tray manufacturers the possibility of having to use less slope in the floor of the room. For example, only two slopes opposite one another need to be provided in the second direction, which correspond to the transverse direction of the device. In contrast, the device can have such a large extension in its longitudinal direction that the water is effectively discharged in this direction. This reduces the effort involved in making screed and shower panels. In addition, there is no work for the production of the tile level in the area of the various gradient transitions.

There is the possibility that the device only extends essentially in the horizontal direction. It is elongated and has on its long sides the upper surfaces, which have a gradient both in the first direction and in the second direction towards the opening. This gradient can, for example, continue the gradient of tiles that can be laid around the device. In this way, the drainage of the water is optimized.

It can be provided that the device, in particular only the molded part and the receptacle of the device in the assembled state, in the third direction has a height or extent between 5 mm and 30 mm, in particular between 5 mm and 10 mm. In this way, the device, or the receptacle with the molded part mounted therein, can be integrated into the tile covering of the floor, so that on the one hand an attractive design results and on the other hand the device can be at least partially mounted on the screed together with the tiles.

In the FIGS. 1 to 16 two embodiments of a device 1 according to the invention can be seen, which are to be arranged at a distance from the wall, for example in the middle of a room. The device 1 according to FIGS. 1 to 16 extends essentially in a plane that corresponds to the horizontal when installed.

The ones in the FIGS. 1 to 8 The first embodiment shown comprises a molded part 2 and a receptacle 3 which, in the assembled state, receives the molded part 1 at least in sections (see FIG Fig. 2 ). Both the molded part 2 and the receptacle 3 each have an opening 4, 5 for the passage of water into the floor drain 6 arranged below the device 1. There is definitely the possibility that the openings 4, 5 are not arranged centrally in the molded part 2 and in the receptacle 3, but rather off-center, for example at the edge.

The molded part 2 and the receptacle 3 are elongated in the X direction or a longitudinal direction and are significantly more extensive in this X direction than in the Y direction or transverse direction perpendicular thereto (see Fig. 1 ).

The molded part 2 can consist of a plastic, in particular a hard plastic or silicone. The receptacle can also consist of a plastic or also of a metal, in particular of stainless steel.

In the position of use, the molded part 2 has a plurality of upper surfaces 7, 8 which, when the device is installed, are inclined relative to the horizontal, so that the water can flow over the upper surface 7, 8 to the opening 4. The upper surfaces 7, 8 in particular have a gradient in the X direction or in the longitudinal direction of the molded part to the opening 4. Furthermore, the upper surfaces 7, 8 also have a slope in the Y direction in sections, by means of which a channel 9 is formed, which leads the water to the opening 4.

FIGS. 6 to 8 show that the depth of the channel 9 increases from the end faces of the molded part 2 to an area in the vicinity of the opening 4, so that the water is guided to the opening 4.

The embodiment according to FIGS. 1 to 8 has a cover 10 which can be applied or introduced onto the molded part 2 in the region of the opening 4. In the cover 10 there is at least one drain opening 11 which opens into the opening 4 through which the water can flow to the floor drain 6 arranged below the device.

The at least one drainage opening 11 of the cover 10 is slot-like in the illustrated embodiment and extends predominantly in the X direction. The parts of the cover 10 which are arranged next to the drain opening 11 in the Y direction have a gradient in the Y direction towards the drain opening 11. There is the possibility that the parts of the cover 10 which are arranged next to the drain opening 11 in the X direction have a gradient in the X direction towards the drain opening 11.

There is also the possibility that the drain opening 11 extends both in the X direction and in the Y direction. In the example shown, the drain opening 11 is arranged in the middle. Alternatively, this at least one drainage opening 11 could also be arranged on the edge. Instead of at least one slot-shaped drainage opening, one or more differently designed, for example circular or rectangular drainage openings can be arranged in the cover 10.

Alternatively, there is the possibility, not shown, that the cover 10 is surrounded by a circumferential gap which opens into the opening 4. The circumferential gap or the, for example, slot-shaped drainage opening 11 can be designed so narrow that they are barely visible to the viewer.

When the device 1 is installed, the receptacle 3 is open at the top and has a base 12 and a frame 13 extending around the base 12. The opening 5 is cut out in the center of the base 12. The frame 13 surrounds the molded part 2 in the assembled state. The frame 13 is adapted to the contour of the molded part 2, in particular on the front side (see FIG Fig. 2 ). In particular, the top of the molded part 2 is flush with the top of the frame 13 (see also, for example Fig. 6 ).

The molded part 2 can be introduced into the receptacle 3 and, in particular when the device 1 is installed, can also be removed therefrom. As a result, the molded part 2 can be removed for cleaning purposes. However, the molded part 2 can also be replaced, for example, by a molded part 2 of different design or of a different color.

There is also the possibility of fastening the molded part 2 in the receptacle 3 during assembly so that it can no longer be removed. This can be done, for example, by gluing.

The floor drain 6 is mounted on the raw floor before the screed is applied and connected to a drain pipe. The screed is then applied to the raw floor so that the floor drain 6 is at least partially surrounded by the screed. The floor, including the drainage parts that have already been installed, is then sealed, in particular provided with a composite seal. The device 1 is then applied to the composite seal.

For this purpose, a substructure 14 protrudes downward from the receptacle 3 and can stand on parts of the floor drain 6 in the assembled state. In particular, the substructure frame 14 can be displaced horizontally or in the X direction and in the Y direction on the floor drain 6 in order to correct the position of the device 1. The water that has entered the drain opening 11 of the cover 10 can enter the floor drain 6 through the openings 4, 5 of the molded part 2 and the receptacle 3 as well as through the substructure frame 14.

The frame 13 of the receptacle 3 has in particular a height such that the receptacle 3 with the molded part 2 in one Floor covering, in particular made of in Fig. 3 floor tiles 15 shown, can be integrated. The second upper surfaces 7, 8 of the molded part 2 and the cover 10 can be shaped in such a way that an inclination of the floor tiles 15 continues on the upper surfaces 7, 8 and / or the cover 10.

The molded part 2 and the receptacle 3 of the device 1 preferably have a length in the X direction of 100 mm to 2500 mm. The molded part 2 and the receptacle 3 of the device 1 preferably have a width in the Y direction of 10 mm to 250 mm. The molded part 2 and the receptacle 3 of the device 1 preferably have a height in the Z direction of 5 mm to 30 mm.

In particular, there is the possibility that the molded part 2 and the receptacle 3 of the device 1 have a height in the Z direction between 5 mm and 10 mm. A flush finish of the upper sides of the molded part 2 with the surrounding tiles can be achieved by means of a suitable height of the substructure frame 14. This can be cut to length for thin tiles.

The embodiment according to FIGS. 1 to 8 furthermore has a support part 16, which consists, for example, of sheet metal or of hard plastic. The support part 16 is arranged between the molded part 2 and the receptacle 3 and surrounds the opening 5 of the receptacle 3. The support part 16 prevents the molded part 2 from bending downward in the area of the opening 5.

The support part 16 can also be dispensed with, in particular when the opening 5 is comparatively small.

The second embodiment of the device 1 according to FIGS FIGS. 9 to 16 differs from the first embodiment according to FIG FIGS. 1 to 8 only by the fact that no separate Cover is provided. Rather, the opening 4 in the molded part is slit-shaped so that it takes over the function of the drain opening 11 in the cover 10 of the first embodiment.

In a further exemplary embodiment, not shown, no prefabricated molded part is used. Rather, the molded part is only created during assembly and converted into the final contour in the process. This can be done by pouring a liquid or foam-like material into the receptacle 3.
