Device for fixing a toilet to a wall and toilet arrangement with a corresponding device

Description

[0001] The present invention relates to a device for mounting a toilet to a wall and to a toilet assembly with a corresponding device. With such devices, toilets and cisterns for holding flushing fluid can be securely mounted to the wall. Devices for mounting a toilet are known, for example, from German patent applications DE102015111423A1, EP1703030A2 and DE102013203941A1.

[0002] Known toilet mounting devices feature a mounting frame to which the toilet and cistern can be attached using a variety of fasteners such as threaded rods, screws, and / or nuts. In addition to standard toilets, so-called shower toilets with an integrated bidet function are also available. These shower toilets may include motorized spray arms that direct a jet of water onto the user's lower abdomen. These spray arms typically require an additional water supply and / or electrical connections for a motor. However, arranging the necessary water and / or electrical connections on known wall-mounted toilet mounting devices has proven challenging due to insufficient installation space. Furthermore, such devices often require significant installation effort.

[0003] The object of the invention is therefore to at least partially solve the problems described with reference to the prior art and, in particular, to provide a device with which toilets can be mounted on a wall with less installation effort. Furthermore, a toilet arrangement is also to be proposed that enables the mounting of a toilet on a wall with minimal installation effort.

[0004] These problems are solved with a device and a toilet arrangement according to the features of the independent claims. Further advantageous embodiments of the invention are specified in the dependent claims. It should be noted that the features listed individually in the claims can be combined with one another in any technologically meaningful way and define further embodiments of the invention. Furthermore, the features specified in the claims are further specified and explained in the description, which also presents further preferred embodiments of the invention.

[0005] This is achieved by a device for fixing a toilet to a wall, which has a mounting frame with at least one mounting crossbar, wherein the mounting crossbar comprises a mounting surface to which the toilet can be fixed by means of at least one fastening element, wherein the mounting surface of the device is arranged such that a mounting space can be formed between the mounting surface and a cover of the device or between the mounting surface and the toilet.

[0006] The device is used to mount a toilet to a wall. Such devices allow toilets to be mounted, particularly on lightweight walls that are unsuitable for direct mounting of the toilet bowl. Furthermore, the device can be used to mount a cistern to the wall, which holds the toilet's flushing fluid. For this purpose, the device includes a mounting frame, which typically comprises several metal profiles. The mounting frame may, for example, have a first vertical metal profile and a second vertical metal profile connected by a (horizontal) upper crossbar and a (horizontal) lower crossbar. The mounting frame may also have feet, allowing its height to be adjusted.

[0007] Furthermore, the mounting frame has at least one mounting bracket with a mounting surface to which the toilet can be attached by means of at least one fastening element. The mounting bracket preferably consists at least partially of metal, in particular sheet metal with a thickness of 1 mm to 5 mm, preferably (essentially) 2 mm. The mounting bracket is preferably arranged (horizontally) between the first vertical metal profile and the second vertical metal profile of the mounting frame. Furthermore, the mounting bracket can be attached to the mounting frame by friction and / or form-fitting means. The mounting surface of the mounting bracket is a region of the mounting bracket in which at least one bore or threaded hole for the at least one fastening element of the toilet is arranged.After the device is attached to the wall, the mounting surface preferably runs (essentially) parallel to the wall. The at least one fastening element is, for example, a threaded rod, a fixing bolt, or a screw. This at least one fastening element can be screwed into the at least one hole or threaded hole in the mounting surface of the mounting bracket and / or secured by means of at least one nut. The toilet can thus be mounted to the mounting bracket of the device by means of this at least one fastening element.

[0008] The mounting surface of the mounting bracket is arranged such that an installation space can be created between the mounting surface and a cover for the device or between the mounting surface and the toilet. The cover can be, for example, at least one panel and / or tile that conceals the device (invisibly) when installed. Thus, there is preferably no direct contact between the mounting surface and the cover or the toilet when the device is installed. The installation space thus gained can be used, in particular, for at least one electrical connection cable and / or a flushing water line of a shower toilet, thereby reducing the installation effort for such toilets. The installation space preferably has a volume of at least 100 cubic centimeters and can, for example, range from 600 to 3,000 cubic centimeters.

[0009] The mounting surface may be recessed relative to the front face of the mounting frame. This means that the mounting surface is not flush with the front face of the mounting frame. The front face of the mounting frame is specifically the surface defined by those surfaces of the metal profiles and / or crossbars that face away from the wall when the device is mounted. When the device is mounted, the mounting surface is offset relative to the front face of the mounting frame, towards the wall. The offset between the front face and the mounting surface can range from, for example, 10 mm to 100 mm.This creates the mounting space in the mounting frame, in particular between the first vertical metal profile and the second vertical metal profile, which, in the mounted state of the device, is located between the mounting surface and the cover of the device or between the mounting surface and the toilet.

[0010] The mounting bracket can have a U-shaped cross-section. The cross-section of the mounting bracket can be hat-shaped.

[0011] The mounting bracket can have at least one contact surface for a cover of the device, wherein the contact surface and the at least one contact surface are spaced apart from each other. The at least one contact surface of the mounting bracket runs, in particular, parallel to the mounting surface of the mounting bracket and / or parallel to the front face of the mounting frame. The distance (horizontal when the device is mounted) between the mounting surface and the at least one contact surface can be, for example, 10 mm to 100 mm.

[0012] The mounting bracket can have at least one groove. Preferably, the mounting bracket has a first groove at its first longitudinal end and a second groove at its second longitudinal end. The at least one groove is, in particular, a channel-shaped depression in the mounting bracket, the depth of which decreases, especially towards the first longitudinal end and / or the second longitudinal end of the mounting bracket (in a horizontal direction when the device is mounted). The at least one groove increases the stiffness of the mounting bracket.

[0013] The device further comprises a junction box with at least one interior space for an electrically conductive element, wherein the at least one interior space can be sealed liquid-tight from the environment. The junction box is made, in particular, at least partially of plastic and / or metal. At least one electrically conductive element, such as an electrical connection cable, a plug of an electrical connection cable, or a transformer, can be arranged in the at least one interior space. Furthermore, a fan can also be arranged in the at least one interior space. Before the installation of a toilet, the at least one interior space can be open in at least one direction. The opening of the at least one interior space can be closed by the toilet after its installation, so that the at least one interior space is sealed from the environment.Furthermore, at least one interior space may have additional openings through which connecting lines, such as electrical and / or water lines, can be routed. These openings may be sealed to prevent liquids from entering at least one interior space. Additionally, a flushing water line for the bidet function of a shower toilet, a flushing water line for the toilet, and / or a wastewater line for the toilet may be routed through the connection box, with at least one interior space also being liquid-tight against these lines. The connection box may also have a T-shaped base.

[0014] The connection box is attached to the mounting bracket. If the connection box has a T-shaped base, it is attached to the mounting bracket, particularly with its horizontal section. Attachment can be achieved, for example, via a screw connection and / or with at least one mounting element for the toilet.

[0015] A flushing water pipe for the toilet, a wastewater pipe for the toilet, a shower water pipe for the toilet, or an electrical connection pipe for the toilet can be routed through the connection box.

[0016] Furthermore, the connection box can extend through a cover of the device and be connected to the cover in a liquid-tight manner. For this purpose, a seal, for example made of silicone, can be provided between the connection box and the cover.

[0017] Following a further aspect, a WC arrangement is also proposed which includes a device described here for fixing a WC to a wall and a WC, wherein the WC is fixed to a fixing surface of a fixing traverse of the device by means of at least one fixing element and wherein an installation space is formed between the fixing surface and a cover of the device or between the fixing surface and the WC.

[0018] For further details of the WC arrangement, please refer to the description of the proposed device for fixing a WC to a wall.

[0019] The invention and its technical context are explained in more detail below with reference to the figures. It should be noted that the figures show a particularly preferred embodiment of the invention, but that the invention is not limited to this embodiment. Identical components in the figures are designated with the same reference numerals. The figures show, by way of example and schematically: Fig. 1: A device with a mounting frame in a perspective view; Fig. 2: A mounting bracket of the mounting frame in a front view; Fig. 3: A side view of the mounting bracket; Fig. 4: The device mounted on a wall in a perspective view; Fig. 5: A connection box of the device; Fig. 6: A detail view of the Fig. 4 in the area of ​​the connection box in a perspective view; and Fig. 7: the wall-mounted device with a cover.

The mounting bracket 5 also has a first contact surface 13 and a second contact surface 36 which run parallel or flush with the front face 11 of the mounting frame 4.

[0021] The Fig. 2 Figure 5 shows the mounting bracket 5 in a front view. The mounting surface 6 has two holes 31 on each side, to which mounting elements 7, 8 (not shown here) for a WC 2 can be attached. The mounting surface 6 has a first groove 14 at a first longitudinal end 37 and a second groove 15 at a second longitudinal end 38. In addition, the Fig. 2 The first facility area 13 and the second facility area 36 can be identified.

[0022] The Fig. 3 Figure 1 shows the mounting bracket 5 in a side view looking at the first groove 14. It can be seen that the mounting bracket 5 has a U-shaped or hat-shaped cross-section 12. The mounting bracket 5 is also made of a formed metal sheet with a thickness of 32.

[0023] The Fig. 4 Figure 1 shows the device after the mounting frame 4 has been attached to a wall 3. A cistern 33 for a flushing fluid of a toilet 2 (not shown) has also been attached to the mounting frame 4, and a connection box 16 has been attached to the mounting bracket 5.

[0024] The Fig. 5 Figure 1 shows the connection box 16 in a perspective view. The connection box 16 has two openings 34 on each of its left and right sides, which, when assembled, align with the openings shown in the figure. Fig. 2The holes 31 shown in the illustration of the mounting surface 6 of the mounting bracket 5 are aligned. The connection box 16 can therefore be attached to the mounting bracket 5 using the fastening elements 7, 8 (not shown here). Furthermore, the connection box 16 shown here has a T-shaped base.

[0025] The Fig. 6 shows a detailed view of the in the Fig. 4The device 1 shown is depicted in a perspective view in the area of ​​the connection box 16. The connection box 16 is attached with its horizontal section to the mounting space 10 of the mounting bracket 5 by a first fastening element 7 and a second fastening element 8. Furthermore, the connection box 16 has a first interior space 17 in which an electrically conductive element 18, similar to a transformer for a (shower) toilet 2 (not shown here), is arranged and into which an electrical connection cable 23 opens. The connection box 16 also has a second interior space 35 into which a shower water line 22 for a (shower) toilet 2 (not shown here) opens. Additionally, a flushing water line 20 extends from the [unclear text], by means of which flushing water is supplied from the [unclear text] in the Fig. 4The flush water line 20 can be routed to the WC 2 shown in the cistern 33, and a wastewater line 21, with which wastewater from WC 2 can be conveyed, for example, into a public sewer, runs through the connection box 16. The flush water line 20 and the wastewater line 21 are held to the mounting frame 4 by the connection box 16. Furthermore, the flush water line 20 extends through the horizontal section of the connection box 16 and the wastewater line 21 extends through a vertical section of the connection box 16.

[0026] The Fig. 7 shows the device 1 after it has been covered by a cover 9.

[0027] The Fig. 8 Figure 24 shows a WC arrangement with a device 1 covered by the cover 9 and therefore not visible, and a WC 2. The WC 2 conceals the device shown in the Fig. 6The first interior space 17 and the second interior space 35 are shown, wherein a seal 39, for example in the form of silicone, is formed between the toilet 2 and the cover 9, so that the first interior space 17 and the second interior space 35 are sealed liquid-tight against the environment 19. This prevents liquid from entering the first interior space 17 and the second interior space 35 when the toilet 2 is cleaned, for example with a high-pressure cleaner, as is not uncommon in public toilets.

[0028] With the present invention, a (shower) toilet can be attached to a wall with minimal effort. Reference symbol list
