Abstract
Description
[0001] The present invention relates to a drainage channel according to the preamble of claim 1 and to a drainage device with such a drainage channel.
[0002] A drainage channel and a drainage device of the aforementioned type are known from EP 2 765 250 A1. The drainage channel described therein is designed for a drainage device arranged adjacent to a wall, at least partially embedded in the floor of a room, wherein the drainage channel is designed such that, in the installed state, a drainage opening can be formed in the area of the lower edge of the wall. The drainage channel comprises a channel base and a back panel, which, in the installed state, can be arranged against the wall. The height of the back panel from its upper end to the underside of the channel base is less than 5 cm, in particular less than 3 cm. Furthermore, the depth of the drainage channel from the wall-side end of the back panel to the room-side end of the channel base is less than 5 cm, in particular less than 3 cm.
[0003] The back wall has a fold at its upper end, resulting in a thickness more than twice that of the material used for the back wall. This leads to a comparatively large thickness of the back wall and a comparatively large depth of the drainage channel from the wall-side end of the back wall to the room-side end of the channel base. Furthermore, the drainage channel has a front wall, at least in sections, which connects to the channel base on the room side. The front wall extends upwards from the channel base in a quarter-circle shape and terminates in a vertical section running parallel to the back wall. This results in a comparatively large height of the front wall from the underside of the channel base to the top edge of the front wall, which is formed by the vertical section running parallel to the back wall.
[0004] The problem addressed by the present invention is the creation of a drainage channel of the type mentioned above, which is more compact and can therefore be more easily integrated into a thin floor covering and / or a thin wall covering. Furthermore, a drainage device of the type mentioned above with such a drainage channel is to be created.
[0005] This is achieved with regard to the drainage channel by a drainage channel of the type mentioned above with the characterizing features of claim 1 and / or claim 3 and / or claim 6, and with regard to the drainage device by a drainage device of the type mentioned above with the characterizing features of claim 12. The dependent claims relate to preferred embodiments of the invention.
[0006] According to claim 1, the height of the front wall from the underside of the channel base to the top edge of the front wall in the at least one second section of the drainage channel is less than 8 mm. The height of the front wall from the underside of the channel base to the top edge of the front wall in the at least one second section of the drainage channel can be less than 7 mm, in particular between 4.5 mm and 6.5 mm, for example approximately 5.5 mm. Such a low height allows the drainage channel to be easily integrated into a thin floor covering.
[0007] According to claim 3, the direction in which the end of the front wall facing away from the channel base extends in the at least one second section of the drainage channel forms an angle of less than 80° with the underside of the channel base, which is horizontally oriented in the installed state of the drainage channel. The direction in which the end of the front wall facing away from the channel base extends in the at least one second section of the drainage channel may form an angle of less than 60° with the underside of the channel base, which is horizontally oriented in the installed state of the drainage channel, particularly between 20° and 50°, preferably between 30° and 40°, for example between 36° and 37°.This relatively small angle results in a relatively low height of the front wall, without at least one second section of the drainage channel losing its water collection function.
[0008] According to claim 6, the thickness of the back panel in the direction extending perpendicular to the wall in the installed state is less than 5 mm. Specifically, the thickness of the back panel in the direction extending perpendicular to the wall in the installed state can be less than 4 mm, in particular between 2 mm and 3 mm, for example approximately 2.5 mm. Such a small thickness of the back panel allows the drainage channel to be easily integrated into a thin wall covering.
[0009] It is possible for the depth of the drainage channel, from the wall-side end of the rear wall to the room-side end of the front wall, to be less than 20 mm, in particular less than 18 mm, preferably between 15 mm and 17 mm. This further increases the compactness of the drainage channel.
[0010] It may be designed so that the first section of the drainage channel is a central section of the drainage channel. For example, a second section may be arranged to the left and right outside the first section.
[0011] It is possible that the channel bottom has a slope in the longitudinal direction of the drainage channel, particularly in at least one second section which slopes longitudinally towards the first section. This ensures that the water reaches the area of the channel from which it can discharge laterally.
[0012] According to claim 12, the drainage channel is a drainage channel according to the invention.
[0013] The drainage device may include a cover under which water can flow from the drainage channel to the water inlet opening. This allows water flowing laterally out of the drainage channel to safely enter a water inlet opening of a drain body pre-installed in the screed. To facilitate the flow of water under the cover from the drainage channel to the water inlet opening, the cover may have a beveled edge on the wall side when installed.
[0014] The drainage device may include a retaining frame for the cover, with the drainage channel and the retaining frame designed to be connected to each other. In particular, the drainage channel may have at least one threaded stud or screw that projects downwards from the drainage channel and can be attached to the retaining frame via a screw connection.

[0016] It is not necessary for a device according to the invention to have all the features described below. It is also possible for a device according to the invention to have only individual features of the embodiments described below.
[0017] The from Fig. 16 The apparent embodiment of a drainage device according to the invention comprises a drainage housing (not shown) which can be connected to a drain pipe provided on site via a drain spigot. The drainage device has a water inlet opening 8 in an upper area (see Fig. 15 ), from which water can enter the drain housing. The drain device also includes a trap (not shown).
[0018] The drainage device further comprises a drainage channel 1 according to the invention, through which the water can enter the water inlet opening 8. The drainage channel 1 is arranged in the transition area from the wall 2 to the floor 3 of the room. The wall 2 can be provided with wall tiles and the floor 3 with floor tiles.
[0019] In the illustrated embodiment, the drainage channel 1 has a first section 6, which is arranged in the middle of the drainage channel 1. The drainage channel 1 further has two second sections 7, which are arranged on the outside and extend to the left and right. Fig. 3 connect to the first section 6.
[0020] The drainage channel 1 is open upwards and towards the side facing away from the wall in the first section 6 or in the area of the water inlet opening 8 (see Fig. 4 and Fig. 15 In this first section 6 of the drainage channel 1, water can therefore flow forwards or to the right into Fig. 4 and Fig. 15 out of the drainage channel 1 and into the water inlet opening 8.
[0021] The drainage channel 1 has a substantially L-shaped cross-section in its first section 6, with a vertical leg that serves as the back wall 4 when installed and projects upwards, and a horizontal leg that serves as the channel base 5. The back wall 4 can either end below the lowest wall tile or be integrated into the wall structure.
[0022] The drainage channel 1 is designed differently in the two second sections 7 and outside the area of the water inlet opening 8. There, on the side opposite the rear wall 4, it has a front wall 9 extending upwards from the channel bottom 5 (see Fig. 4 and Fig. 14 The front wall 9 can prevent water from running out of the drain channel 1 on the tile side.
[0023] The channel bottom 5 has a longitudinal slope towards the first section 6 in the two second sections 7. The back wall 4 is designed identically in the two second sections 7 as in the first section 6. The back wall 4 is significantly more extended vertically than the front wall 9 (see Fig. 4 ).
[0024] The front wall 9 does not extend vertically upwards from the channel bottom 5, but diagonally upwards (see Fig. 4 The direction in which the end of the front wall 9 facing away from the channel base 5 extends with the underside of the channel base 5, which is horizontally oriented in the installed state of the drainage channel 1, forms an angle α that is less than 80°, in particular less than 60°, preferably between 20° and 50°, for example between 30° and 40°. In the illustrated embodiment, the angle α is between 36° and 37°.
[0025] Furthermore, the height H of the front wall 9 from the underside of the channel bottom 5 to the upper edge of the front wall 9 in the second sections 7 of the drainage channel 1 is less than 8 mm, in particular less than 7 mm, preferably between 4.5 mm and 6.5 mm, for example about 5.5 mm (see Fig. 4 ).
[0026] Furthermore, the thickness D of the back wall 4 in the direction extending perpendicular to the wall 2 in the installed state is less than 5 mm, in particular less than 4 mm, preferably between 2 mm and 3 mm, for example about 2.5 mm (see Fig. 4 ).
[0027] Furthermore, the depth T of the drainage channel 1 from the wall-side end of the rear wall 4 to the room-side end of the front wall 9 is less than 20 mm, in particular less than 18 mm, preferably between 15 mm and 17 mm (see Fig. 4 ).
[0028] A cover 10 is arranged next to the drainage channel 1 (see, for example, the figure shown). Fig. 6 ), the upper surface of which can be at the same height as the upper surface of the floor tiles. Accordingly, the water to be drained can pass from the floor tiles over the cover 10 into the drainage channel 1. The wall-side side of the cover 10 can be essentially flush with the wall tiles. This creates a drainage opening, which is arranged as a narrow gap in the wall at its lower end. The cover 10 is only located in a central area of the drainage channel 1, extending over the first section 6 and short portions of the two second sections 7 (see, for example, ). Fig. 16 und Fig. 17 ).
[0029] The side of the cover 10 facing wall 2 is angled so that water in the drain channel 1 can flow under the angled section 11 of the cover 10 to the water inlet opening 8. When installed, the cover 10 can rest loosely on parts of the drain assembly or the floor, allowing it to be lifted upwards to access the odor trap.
[0030] In the illustrated embodiment, the cover 10 is formed by a surrounding frame into which an insert can be placed. The insert can be made of the same material as the floor tiles. However, the cover 10 can also be designed differently, for example as a single piece made of metal.
[0031] The drainage device comprises a retaining frame 12 for the cover 10, wherein the drainage channel 1 and the retaining frame 12 are designed to be connected to each other. In particular, the drainage channel 1 has at least one threaded stud 13 that projects downwards from the drainage channel 1 and can be attached to the retaining frame 12 via a screw connection (see Fig. 6 and Fig. 14 ).
[0032] The drainage device further comprises a base frame 14, which extends downwards from the support frame 12 towards the drainage housing (not shown). The base frame 14 and the support frame 12 can also be connected to each other via the screw connection.
[0033] The installation of a drainage device according to the invention is achieved by first mounting the drainage housing on the subfloor before the screed is applied and connecting it to a drain pipe. The screed is then applied to the subfloor so that the drainage housing is at least partially surrounded by the screed. Finally, the entire floor and wall area, including the already mounted drainage components, is sealed.
[0034] The drainage channel 1 is typically delivered to the construction site pre-assembled, connected to the mounting frame 12 and the substructure frame 14 via a screw connection. The drainage channel 1 is mounted adjacent to the plastered wall. Wall tiles are then applied, which may cover the back panel 4 of the drainage channel 1 from above. The odor trap is inserted, and the cover 10 is loosely placed onto the mounting frame 12. Finally, the floor tiles can be fitted to fit the cover 10.
