Description

[0001] Sanitary facilities

[0002] The present invention relates to a sanitary installation. Such sanitary installations, for example in the form of toilet installations, can serve to receive excrement or liquid and / or solid bodily excretions.

[0003] Sanitary facilities typically include a basin that can be cleaned after use with a flushing fluid, especially water. For this purpose, the sanitary facility may be connected to a cistern to hold the flushing fluid, with a drain valve controlling the flow of the flushing fluid from the cistern into the basin. The basin is mounted on a building wall at a height that allows a user to sit comfortably on it. Depending on the user's height, age, and / or health limitations, the required height of the basin may change. Adjusting the height of the basin would require regularly opening the building wall, which is a time-consuming and costly process.Furthermore, sanitary facilities with electrically height-adjustable washbasins are known. However, these are technically complex and expensive.

[0004] 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 sanitary installation whose sanitary basin can be adjusted in height with minimal effort.

[0005] This problem is solved by a sanitary fitting according to the features of the independent claim. 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.

[0006] This is achieved by a sanitary installation which has a sanitary basin with at least one mounting opening for attaching the sanitary basin to a support, wherein the at least one mounting opening includes a plurality of geometrically defined plug-in positions for a fastening element and wherein the plug-in positions partially overlap.

[0007] Sanitary facilities are particularly suitable for use in sanitary rooms, which may be used, for example, for personal hygiene. For instance, sanitary facilities can be designed as toilets, (sit) toilets, WCs, urinals, or bidets.

[0008] The sanitary facility includes a sanitary basin. This basin can be, for example, a toilet bowl, a urinal bowl, or a bidet bowl. The sanitary basin serves, for example, to collect excrement. To remove the excrement from the sanitary basin, it can be flushed with a flushing fluid, especially water. The sanitary basin may have a siphon. The sanitary basin may have a seat for a user of the sanitary facility and / or a toilet lid. The sanitary basin may be made, at least partially, of ceramic, metal, and / or plastic.

[0009] The sanitary basin has at least one mounting opening for attaching it to a support. The sanitary basin may have multiple mounting openings, for example, two. The mounting openings may be arranged side by side and / or (when the sanitary basin is mounted) at the same height. The mounting openings may be identical. The at least one mounting opening is located, in particular, on the rear side of the sanitary basin. The sanitary basin may be attachable to, or already attached to, the support. The at least one mounting opening may extend from the rear of the sanitary basin to a mounting side of the sanitary basin. The support may be, in particular, a wall, a building wall, or a mounting frame. Such mounting frames are known, for example, as pre-wall elements.These are attached to the building wall and then covered with a partition wall. Wall cladding elements, such as tiles, can then be attached to this partition wall. An access shaft or wall opening can be incorporated into the wall and / or the partition wall. The sanitary basin is attached to the support, specifically at a distance from the floor or building floor.

[0010] The at least one mounting opening has multiple geometrically defined or predetermined insertion positions for a fastening element. All mounting openings of the sanitary basin can each have multiple geometrically defined or predetermined insertion positions for the fastening element. For example, the at least one mounting opening can have 2 to 5 insertion positions for the fastening element. "Geometrically defined" means, in particular, that the insertion positions are at least partially geometrically and / or visibly separated from one another, for example, by a grid or height grid. The insertion positions can extend completely through the at least one mounting opening, for example, from the back to the mounting side of the sanitary basin.The insertion positions can each have a central axis, in particular a straight one, and / or extend along a central axis, in particular a straight one. The central axes can run parallel to each other. The insertion positions partially overlap. In particular, adjacent insertion positions partially overlap. This can mean, in particular, that cross-sections of adjacent insertion positions (especially those orthogonal to the central axes) partially overlap.

[0011] To secure the sanitary basin at different heights, the mounting element can be positioned and / or inserted into different mounting positions. The mounting element can extend through a sleeve and / or a centering element located in the respective mounting position. The centering element can have a centering section located within the sleeve. The sleeve and / or the centering element can be made at least partially of metal. The centering element can be rotatable relative to the sleeve and / or relative to the mounting opening to align the sanitary basin horizontally. The sleeve can have a (second) flange section. The (second) flange section can be located on the mounting side of the sanitary basin. The sanitary basin can be attached to the mounting element, for example, by means of a nut.The nut can be screwed onto the mounting element. The majority of mounting positions do not allow for stepless height adjustment of the sanitary basin. The majority of mounting positions allow for discrete height adjustment of the sanitary basin, for example, in height intervals from 5 mm to 25 mm. The majority of mounting positions can allow for height adjustment of the sanitary basin relative to the support from 30 mm to 50 mm. A number of mounting positions for a single mounting hole can define a number of heights at which the sanitary basin can be attached to the support. The mounting element can be, in particular, a threaded rod. The mounting element can have a length of 100 mm to 200 mm and / or a diameter of, for example, 10 mm to 14 mm, in particular 12 mm.The fastening element is attached to the support (e.g., rigidly). The fastening element is attached to the support and / or in the sanitary room in a way that is not height-adjustable. The fastening element may protrude from the wall, the building wall, and / or the partition wall into the sanitary room.

[0012] The sanitary basin can be easily attached to the support at different heights thanks to the at least one mounting opening with multiple insertion positions, without having to open the wall, the building wall, and / or the partition wall. Furthermore, no additional components are required. Each insertion position can be formed by a recess. The recesses can be shaped like bores. The recesses can be cylindrical. The recesses can form the at least one mounting opening. The recesses can extend concentrically to the central axes and / or completely through the at least one mounting opening, particularly along the central axes. The recesses can extend from the back of the sanitary basin to the mounting side of the sanitary basin.

[0013] The recesses can be round. The recesses can be circular. The recesses can be round or circular, especially if they are perpendicular to the central axes. In particular, the recesses can have a round or circular cross-section.

[0014] The plug-in positions (and / or the recesses) can be arranged one above the other. In particular, the plug-in positions and / or the recesses can be arranged one above the other when the sanitary basin is attached to the support.

[0015] The insertion points (and / or the recesses) can have a diameter of 15 mm to 25 mm. The diameter can be dimensioned, in particular, perpendicular to the central axes.

[0016] The center axes of adjacent insertion positions (or adjacent recesses) can be spaced apart by a distance smaller than the diameter of the insertion positions (or recesses). This distance can be measured orthogonally to the center axes.

[0017] The center axes of adjacent plug positions (or adjacent recesses) can be spaced 5 mm to 20 mm apart. The plug positions (and / or the recesses) can be formed in a receiving housing of the sanitary basin. The receiving housing can be made at least partially of metal, such as die-cast zinc. The receiving housing can be at least partially sleeve-shaped and / or have a (first) flange section. The (first) flange section can be located on the mounting side of the sanitary basin. The receiving housing can be located in a basin opening of the sanitary basin. The basin opening can extend from the rear of the sanitary basin to the mounting side of the sanitary basin. The receiving housing can be positively connected to the sanitary basin and / or the basin opening.

[0018] A flushing water inlet for a sanitary basin can be connected to a flushing water supply line that is at least partially flexible. The flushing water supply line can be telescopic. The flushing water supply line can be made at least partially of plastic. The flexible flushing water supply line allows for the flexible compensation of any height difference between the flushing water inlet of the sanitary basin and a flushing water outlet opening of a supply pipe for the flushing fluid.

[0019] A bathroom sink drain can be connected to a drainpipe that is at least partially flexible. The drainpipe can be at least partially telescopic. The drainpipe can be made at least partially of plastic. The flexible drainpipe can compensate for any height difference between the bathroom sink drain and the wastewater inlet of a sewer pipe.

[0020] The inlet and outlet of a sanitary basin can have a maximum connection distance of 140 mm. The connection distance can be, for example, 130 mm to 140 mm, preferably (essentially) 135 mm. The connection distance can be measured, in particular, from the center of the inlet to the center of the outlet and / or (when the sanitary basin is mounted on the support) in a vertical direction.

[0021] The flush water outlet and the wastewater inlet each have a defined opening distance. This opening distance can be measured from the center of the flush water outlet to the center of the wastewater inlet and / or (when the sanitary basin is mounted on the support) in a vertical direction. The connection distance between the flush water inlet and the wastewater outlet of the sanitary basin can be smaller than the opening distance between the flush water outlet and the wastewater inlet. This ensures that the flush water inlet and the wastewater outlet are not positioned higher than the flush water outlet and that the wastewater outlet is not positioned lower than the wastewater inlet, regardless of the mounting position and / or recess of the mounting hole used to attach the sanitary basin to the mounting element.This ensures that, regardless of the height setting of the sanitary basin, there is the lowest possible flow resistance for the flushing fluid.
