Abstract
Description
[0001] The present invention relates to a drainage channel according to the preamble of claim 1 and a drainage device according to the preamble of claim 9.
[0002] A drainage channel and a drainage device of the aforementioned type are known from EP 3680 406 A1. The drainage device described therein comprises two elongated drainage channels and a housing part which, in the installed state, has an upper opening and a lower opening, wherein water flowing from the drainage channels can enter into the upper opening and wherein water entering through the upper opening can exit from the lower opening. In the assembled state, the two drainage channels are attached to opposite sides of the housing part. Each drainage channel comprises a channel base and two side walls extending upwards from the channel base in the operating position. The side walls are bent downwards at their upper end and extend downwards beyond the channel base. As a result, each drainage channel has a comparatively large overall height.Furthermore, each of the drainage channels has a comparatively large width from the outside of one of the side walls to the outside of the other side walls.
[0003] The problem underlying the present invention is the creation of a drainage channel and a drainage device of the type mentioned above, which can be integrated into the floor of a room in such a way that they are less conspicuous and / or more attractive.
[0004] This is achieved by a drainage channel of the type mentioned above, having the characterizing features of claim 1 and / or claim 4, and by a drainage device of the type mentioned above, having the characterizing features of claim 9. The dependent claims relate to preferred embodiments of the invention.
[0005] According to claim 1, the drainage channel is provided to have a total height of less than 7 mm. The drainage channel can have a total height of less than 6 mm, in particular a total height between 4.5 mm and 5.5 mm, for example a total height of 5.0 mm. Such a low height allows the drainage channel to be easily integrated into a thin floor covering.
[0006] It is possible that the drainage channel between the side walls has a width for the transport of water of 8 mm or less than 8 mm, in particular a width of less than 6 mm, for example a width between 3 mm and 4 mm.
[0007] According to claim 4, the drainage channel has a width of 8 mm or less than 8 mm from the outside of one of the side walls to the outside of the other side walls. The drainage channel can have a width of less than 6 mm from the outside of one of the side walls to the outside of the other side walls, in particular a width between 4 mm and 5 mm. Such a small width allows the drainage channel to be integrated very discreetly into the floor covering.
[0008] The drainage channel can be made of metal, particularly stainless steel. This results in an attractive appearance. Alternatively, the drainage channel can be a bent metal component. It can also be manufactured using 3D printing. Finally, the drainage channel can be made of plastic.
[0009] The channel base may be designed with a slope, particularly if this slope is created by milling. Despite the channel's shallow depth, this slope ensures effective water drainage. Milling also allows for the creation of a suitable slope in very shallow metal channels without compromising their stability.
[0010] The cross-section of the drainage channel can be U-shaped, V-shaped, or, deviating from a U- or V-shape, a freeform shape. Other shapes are also possible. A suitable cross-sectional shape can be selected based on design considerations or local requirements.
[0011] According to claim 9, the two drainage channels, or two of the drainage channels, are arranged to be parallel and transversely spaced apart on the same side of the housing part. The drainage channels may be separated from one another. In particular, the drainage device may comprise four drainage channels, wherein two first drainage channels are arranged to be parallel and transversely spaced apart on a first side of the housing part, and wherein two second drainage channels are arranged to be parallel and transversely spaced apart on a second side of the housing part, facing away from the first side of the housing part. The spaced drainage channels allow for a more aesthetically pleasing integration of the drainage device into the floor of a room.
[0012] It is possible for the housing section to have a receptacle for each of the drainage channels, with each receptacle designed so that one of the drainage channels projects its end into the receptacle. This ensures a stable connection between the drainage channels and the housing section of the drainage device during and after assembly.
[0013] The drainage device may include a cover, in particular wherein the cover is U-shaped and has a base and two side walls extending upwards from the base in the installed position. The drainage device may include two ribs extending outside the cover parallel to the side walls of the cover, so that a slot-shaped opening for water is formed between each of the ribs and a side wall of the cover, in particular wherein the drainage device is configured to allow water flowing from a drainage channel to enter each of the slot-shaped openings. The slot-shaped openings may also receive water that has not flowed from the drainage channels but flows laterally into the openings from a floor covering arranged next to the housing part.
[0014] It may be provided that the slot-shaped openings have a width for the transport of water of 8 mm or less.
[0015] It is possible that the drainage system is designed so that a section of flooring can be placed between the two parallel drainage channels and / or between the two side walls of the cover. This allows both the drainage channels and the housing to be integrated almost invisibly into the flooring.
[0016] It can be provided that the at least two drainage channels are drainage channels according to the invention.

[0018] 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.
[0019] The in Fig. 6 bis Fig. 18 The illustrated embodiment of a drainage device according to the invention comprises four narrow drainage channels 1 (see, for example, Fig. 6 The drainage device further comprises a housing part 2, which has a rectangular frame 3 and a substructure frame 4 extending downwards from the frame 3 in the form of a rectangular tube (see, for example, Fig. 7 ).
[0020] The housing part 2 has two spaced-apart receptacles 15 on each of its opposite end faces, into which the end of one of the drainage channels 1 can be inserted (see Fig. 7 and Fig. 9 ). The spaced arrangement of the receptacles 15 ensures that two separate drainage channels 1 are arranged spaced apart from each other in the transverse direction on each of the end faces of the housing part 2.
[0021] When installed, the housing part 2 has an upper opening 19 and a lower opening 20, whereby water flowing from the drainage channels 1 can enter the upper opening 19 and the water entering through the upper opening 19 can exit through the lower opening 20. The lower opening 20 corresponds to the lower opening of the substructure frame 4 (see Fig. 9 ). When the four drainage channels 1 are inserted into the receptacles 15 of the housing part 2, water flowing via the drainage channels 1 can enter the upper opening 19 of the housing part 2.
[0022] The drainage device further comprises a drainage body 5, which has an upper opening into which water escaping from a lower opening 20 of the housing part 2 or the substructure frame 4 can enter (see Fig. 11 ). At least one drain nozzle 6 is molded onto the drain body 5, which can be connected to a drain pipe provided by the customer.
[0023] The drainage device further includes a trap 7, which can be inserted into the drain body 5 from above. The drainage device further includes a sealing membrane 8, which is attached or can be attached to the top of the drain body 5. The sealing membrane 8 has an opening through which water can enter the drain body 5 from the substructure frame 4 (see Fig. 11 ).
[0024] When the drainage device is installed, a composite seal is applied to the sealing membrane 8, onto which tiles 9 can then be applied (see Fig. 11 ). The substructure frame 4 can be cut to length to adapt it to the thickness of the tiles 9.
[0025] The drainage device includes a cover 10 which can be inserted into the frame 3 (see Fig. 7 The cover 10 is U-shaped and has a base 11 and two side walls 12 extending upwards from the base 11 in the installed position. The cover 10 has an upper recess between the two side walls into which a tile or other section 9a of a floor covering can be inserted.
[0026] It is entirely possible to use a differently shaped cover, for example a cuboid one, instead of a U-shaped cover 10. This cover could, for example, be designed as an insert made of metal, such as stainless steel.
[0027] The cover 10 reduces the water inlet opening to slot-shaped openings 13 (see Fig. 9 These slit-shaped openings 13 have a width WÖ for the transport of water of 8 mm or less than 8 mm (see Fig. 13 ). For this purpose, the housing part 2 includes two webs 14 which extend outside the U-shaped cover 10 parallel to the side walls 12 of the cover 10, so that one of the slot-shaped openings 13 for water is formed between each of the webs 14 and a side wall 12 of the cover 10 (see, for example, Fig. 7 , Fig. 9 and Fig. 13 ). Fig. 15 This illustrates the transition from the drainage channel 1 to the housing part 2. It is shown in Fig. 15 unlike Fig. 14 Cover 10 has been omitted for clarity.
[0028] The cover 10 and the webs 14 can be made of metal, in particular stainless steel. Alternatively, the cover 10 and the webs 14 can be formed as bent metal parts. Alternatively, the cover 10 and the webs 14 can be manufactured by 3D printing. Alternatively, the cover 10 and the webs 14 can be made of plastic.
[0029] The in Fig. 1 bis Fig. 3 The drainage channel 1 shown is comparatively long, narrow, and low. The drainage channel 1 has a channel base 16 and two side walls 17 extending upwards from the channel base 16 in its operating position.
[0030] The cross-section of the drainage channel 1 shows in the Fig. 1 bis Fig. 3 The illustrated embodiment features a freeform shape in which a concave recess is formed for water transport. The cross-section of the [unclear text] Fig. 4 The illustrated embodiment of the drainage channel 1 is essentially U-shaped, whereas the cross-section of the Fig. 5 The illustrated embodiment of the drainage channel 1 is essentially V-shaped. Other shapes are certainly possible.
[0031] The channel base 16 of the drainage channel 1 has a slope that ensures water transport to the housing part 2 of the drainage device. Fig. 2 shows that the end of the drainage channel 1 facing away from the drainage device has a channel bottom 16 positioned significantly higher than the one in Fig. 3 The end of the drainage channel 1, facing the drainage device, is shown. The gradient is shown in the sectional views of the Fig. 16 bis Fig. 18 clarifies.
[0032] The drainage channels 1 can be made of metal, in particular stainless steel. The slope can be created by milling into the channel base 16.
[0033] Alternatively, the drainage channels 1 can be designed as a bent metal component. Alternatively, the drainage channels 1 can be manufactured using 3D printing. Alternatively, the drainage channels 1 can be made of plastic.
[0034] Each of the drainage channels 1 has a total height H of less than 7 mm, in particular a total height between 4.5 mm and 5.5 mm, for example a total height of 5.0 mm. In the illustrated design of the drainage channel 1, the total height H is determined by the distance between the underside of the channel base 16 and the top of the side walls 17.
[0035] It may be provided that each of the drainage channels 1 between the side walls has a width WR for the transport of water of 8 mm or less than 8 mm.
[0036] In the illustrated embodiment (see Fig. 3 Each of the drainage channels 1 has a width B of less than 8 mm, in particular a width between 4 mm and 5 mm. In the illustrated design of the drainage channel 1, the width B is determined by the distance from the outer surface of one of the side walls 17 to the outer surface of the other side walls 17. Therefore, in this embodiment, the width WR is significantly less than 8 mm.
[0037] The in the Fig. 6 bis Fig. 9 The illustrated embodiments of the drainage channels 1 have support strips 18 on the lower sections of the outer sides of the side walls 17. These support strips 18 serve as a bearing surface for the tiles 9 that adjoin the respective drainage channel 1. The thickness of each of the support strips 18 corresponds approximately to the typical thickness of a joint between the tiles 9.
[0038] Fig. 10 This indicates that a section 9a of floor covering can be arranged between the two parallel drainage channels 1. Alternatively, an insert with a different appearance than the floor covering can be placed here. Furthermore, this indicates Fig. 10 bis Fig. 12 that a section 9a of a floor covering is arranged between the two side walls 12 of the cover 10.
[0039] To simplify the parallel arrangement of the two drainage channels 1, which are to be mounted at a distance from each other, it is possible to provide one or more spacers, which can, for example, be included with the drainage device in its delivered state.
[0040] It can also be provided that the two drainage channels 1 are firmly connected to each other via suitable connecting elements, the connecting elements remaining in the floor after the drainage channels 1 have been installed. In particular, a section 9a of the floor covering, such as a tile, can be applied to the top of the connecting elements.
[0041] A corresponding embodiment is described in the Fig. 19 und Fig. 20 The two drainage channels 1 are connected by an intermediate piece 21, which serves as a connecting element. The side walls 17' of the drainage channels 1 facing the other drainage channel 1 are lower than the outer side walls 17 of the respective drainage channels 1. The side walls 17' facing each other correspond to the outer sides of the intermediate piece 21.
[0042] A tile section or another section 9a of a floor covering can be applied to the intermediate piece 21 (see Fig. 20The intermediate piece 21 and the section 9a of the floor covering together have a height that corresponds to the height of the outer side walls 17.
