    CH 710 857 B1
    Description: The present invention relates to a sanitary tub arrangement with a tub body which has a drain opening and a depression surrounding the drain opening on a tub floor, with a drain fitting connected to the drain opening of the tub body and with a cover arranged above the drain fitting, which extends into the depression is used and has a larger footprint than the drain opening.
    The tub body can be a shower tray, bathtub or a sink. Such tub bodies are usually formed from steel enamel, mineral casting, ceramic, sanitary acrylic, other plastics or composite materials.
    The tub body then forms - even with a very flat, floor-level shower - a basin by collecting the water from a tap, shower head or the like and leading to the drain opening. The drain fitting is then connected to the drain opening and has the cover in the form of a lid on its upper side.
    In simple configurations of the tub body and drain fitting, such a cover protrudes as a cover in the tub body, in which case the water flows in laterally. If the cover has a smaller footprint than the drain opening, it can also be used as a simple plunger in the drain fitting. A large number of corresponding designs are known from practice.
    In addition, generic sanitary tub arrangements are known in which a recess is provided in the tub floor around the drain opening, which can accommodate the cover, which has a larger base area than the drain opening. The water then usually flows along the edge through a gap between the cover and the depression and then reaches the drain opening below the cover. The cover is then at least partially inserted into the depression and, depending on the configuration of the depression, can be flush with the adjacent area of the tub floor. Generic sanitary tub arrangements are known for example from DE 10 2009 023 015 A1, DE 20 2013 105 431 U1, DE 20 2011 109 947 U1, DE 10 2011 000 272 A1 and DE 10 2005 011 790 B3.
    In order to provide a shower space, designs are also known in which, instead of a shower tray, a floor area sloping towards an outlet is provided, which is generally tiled. The drain fitting is then inserted into the floor, for example in the screed of a bathroom, a cover layer of tiles or the like then being brought up to the drain during the further construction of the substrate. Optionally, such a drain set can also be connected to a support to be tiled.
    From DE 10 2004 011 853 A1 a drain device is known, which can be adapted in its construction both for a tiled shower area and for connection to a tub body, a simple grille being provided as a cover for the drain set in a tiled shower area is. A corresponding grid as a cover is also known from DE 10 2010 046 179 A1.
    According to DE 20 218 799 U1, a grating is provided which, in a star-shaped arrangement, has a plurality of slits running obliquely downwards.
    In addition, various designs of drainage channels are known, for which reference is made to DE 20 2006 014 745 U1 by way of example.
    Starting from a generic sanitary tub arrangement with a tub body, the invention is based on the object of specifying an embodiment of the cover which is inexpensive to manufacture, requires a small installation space and is easy to handle.
    The object of the invention and the solution to the problem is a sanitary tub arrangement according to claim
    1. Starting from a generic configuration, it is provided according to the invention that the cover has a central section and an edge section surrounding the central section in a frame-like manner, the cover being supported downward on the recess and / or the drain fitting at the edge section and having a water passage opening on the central section has an upper edge and a lower edge formed by a free end of a downwardly sloping water guide surface.
    The present invention thus relates to a sanitary tub arrangement with a tub body and a recess around the drain opening, in which the cover is inserted. Starting from such a basic construction, however, it is provided according to the invention that the water flows off through a water passage opening inside the cover and not on the edge as in the known designs.
    At the frame-shaped edge section, the cover lies on its underside on the drain fitting and / or the recess directly or indirectly, so that water flows exclusively or at least for the most part through the water passage opening during use. However, since a continuous tub body is provided up to the drain opening, it is generally not harmful if small amounts of water get under the cover at the edge section.
    CH 710 857 B1 [0014] According to the invention, the cover is furthermore not designed as a simple grid, but with a water guiding surface that slopes downward at an angle. It can thereby be achieved that the gap formed between the upper edge and the lower edge runs vertically or approximately vertically.
    Preferably, the gap extending between the upper edge and the lower edge of the water passage opening is arranged at an angle between +/- 45 ° with respect to the vertical.
    Due to the downwardly sloping water guide surface, the water is effectively directed into the drain fitting, whereby the drain fitting underneath is covered to a certain extent by the vertical or oblique gap - unlike a simple grid.
    Basically, the drain opening with the recess arranged around it and the cover inserted into the recess can be arranged at any point on the tub floor. According to a preferred embodiment of the invention, however, it is provided that the drain opening is arranged and the cover is inserted such that the gap formed between the upper edge and the lower edge of the water passage opening is not visible to a user. This is achieved by an arrangement in which the water guide surface slopes away in the direction of the usual position of the user, so that from the user's point of view the free end of the water guide surface as the lower edge of the water passage opening is covered by the upper edge. In the arrangement described, the user only looks at the top of the cover and the sloping water guide surface, the water passage opening itself being covered.
    Against this background, the cover preferably has only one water passage opening or a plurality of water passage openings with the same orientation.
    In particular, it can be provided in a shower tray that the drain opening is arranged adjacent to a straight edge section of the tub body, the cover being arranged such that the water guiding surface slopes downward from the adjacent edge section in the direction of the free end. The distance between the drain opening and the adjacent edge section can in particular be less than 300 mm, preferably less than 200 mm. When a user is in a central position on a tub body in the form of a shower tray, the gap formed between the lower edge of the water passage opening is then covered as previously described.
    Even if fundamentally different geometries are possible within the scope of the invention, the cover preferably has an at least substantially flat upper side, the water guiding surface then falling obliquely from the flat upper side in the direction of its free end. In principle, however, it is also conceivable that the upper edge is drawn upwards from the essentially flat edge section in order to allow water to enter.
    So that the water can reach the water passage opening, at least the edge section is inserted into the depression in such a way that it is flush with the area adjoining the depression or springs back.
    In order to achieve a high-quality appearance, a small space requirement and a large passage volume, it is provided according to a preferred embodiment of the invention that the base area of the cover deviates from a circular or square shape, the ratio of a width running through the center of the area to a length determined perpendicular to it is at least 3: 2. The cover can, for example, have an elongated rectangular shape or an oval shape. In addition, for example, the two long sides can also be formed by semicircles, each of which is connected in the width direction by straight sections. At least with the geometric structures described, the assignment of the width and the length is readily possible.
    [0023] According to a preferred embodiment of the invention, the ratio is at least 2: 1. The upper edge and the lower edge of the water passage opening expediently run parallel to the width, so that a comparatively long gap can then be provided between the upper edge and the lower edge of the water passage opening, which enables a large water passage volume.
    The drain opening of the tub body, which is arranged under the cover, can have a shape deviating from a circle or a square, the ratio of a width running through the center of the area to a length determined perpendicularly thereto being at least 3: 2, particularly preferably at least 2: 1.
    According to a preferred embodiment of the invention, the distance between the upper edge and the lower edge of the water passage opening is between 4 mm and 10 mm. If the distance is too small, the flow rate will decrease, but if the distance is too large, a risk of injury cannot be excluded. The gap between the upper edge and the lower edge should expediently be chosen so that large particles or a user's fingers can be retained.
    The cover can be formed in a particularly simple manner from two parts, namely an upper part and a lower part. The top then forms the visible surface of the cover while supporting the cover
    CH 710 857 B1 down over the lower part. The lower part can in particular have a frame shape and extend on the edge portion of the cover.
    A two-part design results in particularly low production costs, the lower part and the upper part also being formed from different materials and being able to be optimally adapted to the respective requirements. For example, the upper part can be made from a simple sheet metal, which can then be punched, bent or deep-drawn to form the water passage opening. Depending on the optical requirements, the upper part can be formed, for example, from an uncoated stainless steel sheet or a coated sheet. Plastic coatings, enamelling or painting are particularly suitable as coatings.
    Alternatively, it is also possible that the water guide surface is formed by the lower part, so that the upper part can then be manufactured particularly easily and only has to have a cutout above the water guide surface. The upper part then only forms a kind of design cover and can be easily adapted to different requirements. In the case of production from sheet metal or another layer material, only punching or cutting, for example with a laser, is necessary in order to form the upper part. Such a configuration is particularly suitable for individual customer requests and small series.
    In a two-part design of the cover, the lower part can in particular be made of plastic, in which case snap-in formations or the like can then be formed in a simple manner. Production by an injection molding process is preferred.
    In principle, however, it is also possible within the scope of the invention to either produce the cover in one piece or to form it from more than two parts. A one-piece production is possible in particular by plastic injection molding in order to produce suitable connection structures on the underside. Even in the case of one-piece production from plastic, at least the visible surfaces of the cover are preferably coated, it being possible, depending on the requirements, to apply a layer of lacquer or a type of chrome plating.
    Since the cover is inserted into the recess, a certain positive locking against slipping can be achieved without further measures. According to a preferred embodiment of the invention, however, a further securing of the cover against slipping or a willful or accidental removal is provided.
    For example, the cover on the one hand and the drain fitting on the other hand can be provided with protruding pins and associated bores to prevent slipping.
    In addition, it is also possible that the cover can be placed on the drain assembly in an assembly position, the cover and the drain assembly having mutually associated guide structures which enable the cover to be transferred from the assembly position to the end position. The guide structures can form a linear guide, for example.
    For example, it can be provided that the cover is first placed with an offset in relation to the depression and then moved during the transfer from the assembly position into the end position to a central arrangement above the depression and finally lowered in a further step. This ultimately results in a three-stage movement when the cover is put on (downwards, sideways, downwards), which offers particularly secure fixing and even a certain protection against vandalism. A user will not easily be able to remove the cover without practice, but easy handling is possible if the mode of operation is known.
    [0035] The invention is explained below on the basis of a drawing which represents only one exemplary embodiment. It shows:
    1 shows a sanitary tub arrangement with a tub body in the form of a shower tub,
    2 shows an exploded view of the sanitary arrangement according to FIG. 1, the tub body being shown only in a detail,
    3 the detail according to FIG. 2 in a perspective sectional view,
    4 individual parts of a cover,
    Fig. 5 shows a lower part of the cover according to FIG. 4 and a clamping ring of a drain fitting.
    1 shows a sanitary tub arrangement with a tub body 1 in the form of a flat shower tray. A drain opening 2 in a trough base of the trough body 1 is covered by a cover 3, the cover 3 being inserted flush or slightly recessed into a recess 4 in the trough base.
    Further details of the sanitary tub arrangement result in particular from FIG. 2, in which the tub body 1 is only shown in a small section and the other components of the sanitary tub arrangement are shown in an exploded view. First of all, it can be seen that the depression 4 surrounds the drain opening 2, the
    CH 710 857 B1
    Drain opening 2 has a greater width bi than length h. The short long sides are each formed by semicircles, which are connected along the width of straight sections. The ratio of the width bi to the length h is more than 2: 1. The cover has a similar ratio of width b 2 to length l 2 . A drain fitting 5 is connected to the drain opening 2, the drain fitting 5 having a drain pot 6, a collar seal 7 and a clamping ring 8. A siphon insert 9, which can be removed upwards, is also arranged inside the drain pot 6.
    During assembly, the collar seal 7 is arranged on the edge of the drain opening 2. The drain pot 6 is then placed on the underside of the tub body 1 on the collar seal 7 and mounted from above with the clamping ring 8, the clamping ring 8 being arranged in the depression 4 of the tub bottom. In the exemplary embodiment, the clamping ring 8 and the drain pot 6 are connected in a known manner by screws 10.
    From Fig. 2 it can also be seen that the cover 3 arranged on the drain fitting 5 and covering the drain opening 2 is formed from an upper part 11 and a lower part 12.
    The cover has a central section with a water passage opening 13 and an edge section surrounding the central section in the form of a frame, the cover 3 being supported on the edge section downward on the depression 4 and / or the drain fitting 5. In the exemplary embodiment shown, the cover 3 is supported on the clamping ring 8 of the drain fitting 5.
    It can be seen from FIG. 2 that the lower part 12 extends at the edge section of the cover 3, the water passage opening 13 having an upper edge 14 and a lower one hidden at the viewing angle according to FIGS. 1 and 2 Has edge 15. The lower edge 15 is formed by the free end of a water guiding surface 16 sloping downwards.
    The gap 17 formed between the upper edge 14 and the lower edge 15 of the water passage opening 13 can be seen in the sectional view according to FIG. 3. It is also clear that the gap 17 cannot be seen in the usual viewing direction of a user (see FIG. 1) because the cover 3 is arranged adjacent to a straight edge section of the tub body 1, the water guiding surface 16 starting from the adjacent edge section of the Tub body 1 drops down towards the free end. In other words, the gap 17 formed between the upper edge 14 and the lower edge 15 is covered by the upper edge 14 from a viewing direction centrally above the tub body 1.
    From the sectional view according to FIG. 3 it can also be seen that the gap 17 between the upper edge 14 and the lower edge 15 is oriented approximately vertically. An exact vertical alignment of the upper edge 14 and lower edge 15 is not necessary. The gap 17 preferably extends at an angle between +/- 45 ° with respect to the vertical axis.
    As can already be seen from FIG. 2, the cover 3 is formed by an upper part 11 and a lower part 12. The upper part 11 can be manufactured in a particularly simple manner from a sheet metal or another layer material, in which case the water guiding surface 16 can then be produced by embossing, deep drawing or bending. The lower part 12, on the other hand, is intended to fasten the cover 3 on the drain fitting 5. The lower part 12 accordingly forms a type of adapter which can be glued to the upper part 11 in a particularly simple manner. Accordingly, the lower part 12 according to FIG. 2 has a structure on its upper side which enables the application of an adhesive. In contrast, 12 are provided on the underside of the lower part, which enable a connection to the clamping ring 8 of the pop-up valve 5.
    Thus, on the one hand, there are simple cylindrical pins 18 and guide webs 19 on the underside of the lower part 12. When mounting the cover 3 on the drain fitting 5, the cover 3 is first placed with a lateral offset in the direction of the width, the guide webs 19 engage in assigned slots 20. Due to the lateral offset, the cover 3 still protrudes over the recess 4. The guide webs 19 are then laterally displaced in the slots 20 until the cover 3 is arranged centrally above the depression 4. The cover 3 is then lowered, the pins 18 engaging in associated openings 21 in the clamping ring 8 and ensuring a secure fixation of the cover 3 against slipping.
