Definitions

  • the invention relates to a sanitary tub, in particular a shower tray, preferably made of steel enamel, with a base, a drain opening formed in the base and an annular flange produced separately from the tub, which defines a connection surface and on the underside of the base of the tub is arranged and surrounds the drain opening.
  • a sanitary tub is to be understood as meaning, for example, a bathtub or a deep or flat shower tub, the latter also being able to be referred to as a shower tray.
  • a shower tray is also understood here to mean those shower trays that are designed to be particularly flat, in particular those that do not have an upwardly protruding shower tray edge on their circumference.
  • Conventional bathtubs and shower trays are made of steel enamel or fiber-reinforced plastic and have a trough or surrounding recess in the edge area of their drainage opening (see e.g. DE 10 2006 030 481 A1 ).
  • the surrounding recess is used to fix a drain fitting by means of a connecting counterpart in the form of a flange.
  • the circumferential recess is produced by reshaping, usually by embossing the edge area of the drainage opening of the bathtub or shower tray. After reshaping the sheet steel and cutting it out, e.g. B. punching out the drain opening - and possibly cutting out an overflow opening - the tub or shower tray body is enamelled.
  • the invention is based on the object of creating a sanitary tub, in particular a shower tray of the type mentioned, which differs from conventional bathtubs and shower trays in terms of the shape in the area of the drain opening and yet has a liquid-tight connection of a drain fitting to the drain opening of the Tub allows.
  • the tub according to the invention which can be designed in particular in the form of a flat shower tray, is characterized in that the flange is connected to the bottom of the tub in a liquid-tight manner without a connecting counterpart, for example a fastening flange, resting on the top of the bottom of the tub, and that the Flange which defines a connection surface and is arranged on the underside of the bottom of the tub and surrounds the drain opening, is connected to a drain housing of a drain fitting or is prepared for a detachable connection to a drain housing of a drain fitting.
  • a connecting counterpart for example a fastening flange
  • the present invention is based on the idea of design parts of a bathtub or shower tray, in particular one made of steel enamel, in the area of the drain opening to be produced by flat components or floor sections without a high degree of deformation. All or almost all functional parts in the area of the drainage opening should be arranged in the non-visible area under the cover (drainage hood) and thus hidden.
  • An advantageous embodiment of the tub according to the invention, in particular the shower tray, is characterized in that the tub preferably has no circumferential embossing in an edge area surrounding the drain opening in a ring shape, which extends away from the drain opening, this edge area having a circumferential or radial edge width in the range from 10 mm to 80 mm, preferably in the range from 50 mm to 80 mm.
  • no small bending radii, in particular no S-shaped bending contours are formed in the said edge area.
  • this edge area directly adjoining the drain opening which has a circumferential or radial edge width in the range from 10 mm to 80 mm, preferably in the range from 50 mm to 80 mm, is essentially designed without a circumferential embossing and thus particularly flat.
  • the tub in particular the shower tray, is thus largely or largely flat in the edge region of the drain opening.
  • the drain opening can be produced by cutting the tub bottom in the area of a provided floor drain using lasers, punching or similar cutting processes, without plastically reshaping the tub bottom in the edge region of the drain opening.
  • the depth of this minimal circumferential embossing is, for example, in the range from 2 mm to 20 mm, preferably in the range from 2 mm to 15 mm, particularly preferably in the range from 2 mm to 10 mm.
  • the drain opening of the tub according to the invention is preferably delimited by a perforated edge which has an edge radius in the range from 0.25 mm to 2.5 mm, preferably in the range from 1.0 mm to 2.0 mm.
  • the flange can also be referred to as an adapter flange.
  • the flange is positively, cohesively or non-positively connected to the tub.
  • Another advantageous embodiment of the invention is characterized in that the flange is glued to its connection surface with the underside of the tub.
  • Such a material connection can be implemented cost-effectively in terms of production technology.
  • the adhesive connection enables a liquid-tight connection of the flange to the tub at the same time.
  • the underside of the bottom of the tub is provided with pin-shaped or bolt-shaped fastening means, the flange having a plurality of through holes for receiving the fastening means in the region of its connection surface.
  • the fastening means can be designed, for example, as screw bolts connected to the underside of the tub bottom.
  • the fastening means can also be locking bolts.
  • a sealing ring can be arranged between the tank bottom and the flange. It is also possible to combine this non-positive connection with the adhesive connection specified above, the adhesive or a double-sided adhesive sealing ring ensuring a liquid-tight connection of the flange to the tub.
  • Another advantageous embodiment of the invention is characterized in that the flange has several through holes for anchoring adhesive in the area of its connection surface. In this way, a particularly reliable fixation of the drain fitting on the shower tray or tub can be achieved.
  • a further embodiment of the invention consists in that the drain opening is provided with a cover which, together with the drain opening, delimits a circumferential inlet gap, the top of the cover being flush with the top of the edge area surrounding the drain opening.
  • the cover hood can also be referred to as a drain hood.
  • the cover hood covers an inlet opening of the drain fitting and creates an attractive design. The flush arrangement of the covering hood relative to the surrounding edge area prevents a person using the tub from possibly painfully striking the peripheral edge of the covering hood with a foot.
  • the top of the cover (drainage hood) is typically clearly visible to an observer when the drainage fitting is installed and in its intended condition.
  • the top of the cover can therefore also be referred to as a decorative top or is designed as a decorative top.
  • the decorative top of the cover can be implemented, for example, by a decorative plate arranged on the top of the cover.
  • the top of the cover hood or decorative plate can be designed to be essentially flat or slightly curved upward.
  • the inlet gap delimited by the tub drain opening and the cover hood has, for example, a gap width in the range from 1.0 to 8 mm, preferably in the range from 1.5 mm to 4 mm, particularly preferably in the range from 1.5 mm to 2.5 mm.
  • the drain opening has an inside diameter of at least 130 mm, preferably at least 150 mm, particularly preferably at least 180 mm.
  • the inside diameter of the drain opening can also be at least 200 mm.
  • An upper limit for the inside diameter of the drain opening can be, for example, 250 mm, 300 mm or 400 mm. However, even larger inner diameters are also conceivable for the drain opening of the tub.
  • the cover is preferably arranged such that the perforated edge of the drain opening and the hood edge defined by the cover are butted against each other, delimiting the inlet gap.
  • the circumferential inlet gap has an inlet cross-sectional area in the range from approx. 1500 mm 2 to approx. 3500 mm 2 , preferably in the range from approx. 1500 mm 2 to approx 3000 mm 2 , particularly preferably in the range from approx. 1200 mm 2 to approx. 2500 mm 2 , in particular in the range from approx. 1200 mm 2 to approx. 2000 mm 2 .
  • a further advantageous embodiment of the invention provides that the cover hood has spacers on its underside, with which it rests on an inlet surface of the flange that is lower relative to the connection surface of the flange. In this way, with a flush arrangement of the cover hood relative to the surrounding edge area of the tub bottom, stable mounting of the cover hood can be achieved in a favorable manner.
  • the flange has a horizontal outer dimension which is greater than a horizontal outer dimension of the cover hood that is aligned relative to the outer dimension of the flange.
  • the present invention significantly extends the scope for the design of a shower tray, in particular a shower tray made of steel enamel.
  • a shower tray designed according to the invention enables a drain fitting to be reliably fixed to the shower tray without a circumferential indentation (embossing) in the edge area of the drain opening of the shower tray.
  • the invention offers the possibility of producing design parts in the area of the drain opening of the shower tray using flat components without a high degree of deformation. All functional parts in the area of the drain opening can be arranged in the non-visible area under the cover and thus hidden.
  • the horizontal outer dimension of the flange is preferably at least 5%, preferably at least 10%, particularly preferably at least 15% greater than the horizontal outer dimension of the cover hood, which is aligned in the same direction relative to the outer dimension of the flange.
  • An upper limit for the horizontal outer dimension of the flange can be, for example, approximately 150% of the rectified, horizontal outer dimension of the cover hood.
  • the drain opening of the shower tray and the cover hood are preferably designed to be circular.
  • the above-mentioned horizontal external dimension can then also be referred to as the (horizontal) external diameter.
  • An advantageous embodiment of the invention is characterized in that the flange and / or the drain housing has an inlet surface lying lower relative to the connection surface of the flange, which surrounds the inlet opening of the drain housing when the drain fitting is installed and is spaced from the underside of the cover hood.
  • the cover hood preferably has spacers on its underside, with which it rests on the inlet surface.
  • a circumferential annular groove for receiving an annular seal for example an annular elastomer seal

  • a ring seal inserted into the ring groove ensures a reliable liquid seal between the shower tray or tub and drain fitting, especially when the connection surface of the flange is subsequently glued to the underside of the tub or shower tray base.
  • this configuration can ensure that the adhesive is effectively sealed off from the water drainage area of the drain fitting, so that shower or bath water cannot get to the adhesive.
  • connection surface of the flange is connected in one piece to the inlet surface surrounding the inlet opening of the drain housing via a conical inlet surface.
  • the conical inlet surface promotes the drainage of water into the drain housing and prevents dirt from sticking to the inlet surface to a large extent.

  • the spacers formed on the underside of the cover preferably have beveled edges on their outer sections, the respective beveled edge defining an angle relative to a horizontal plane which essentially corresponds to the angle of inclination of the conical inlet surface. In other words, the beveled edge of the spacer runs essentially parallel to the contour of the conical inlet surface.
  • the inlet surface which is lower relative to the connection surface of the flange, is inclined, preferably conical, towards the inlet opening of the drain housing.
  • the inlet surface is limited to the outside by a circumferential shoulder or a circumferential inner wall.
  • the inclined, preferably conical inlet surface promotes the drainage of water into the drain housing and prevents dirt from adhering to the inlet surface to a large extent.
  • the cover hood can also be easily and reliably centered on the circumferential shoulder or on the circumferential inner wall relative to the drain opening of the tub.
  • the cover has on its underside, for example, a plurality of spacers, for example rib-shaped or web-shaped spacers, which protrude radially beyond the outer edge of the cover.
  • the outer end faces of the spacers abut against the circumferential shoulder or the circumferential inner wall or end with very little play relative to the shoulder or the inner wall.
  • the spacers are preferably designed in such a way that their ends protruding radially over the outer edge of the covering hood or over the outer edge of a carrier of a decorative panel of the covering hood are inclined or stepped towards the outer end face.
  • the spacers are barely visible through the inlet gap, which is advantageous for the aesthetic design of the inlet gap.
  • this configuration also optimizes the drainage capacity of the drainage fitting with a small width of the inlet gap.
  • the cover hood or the decorative plate attached to the carrier preferably has a closed or substantially closed top side.
  • a substantially closed top side means a top side that optionally has a single or multiple through openings, the area proportion of the through opening or through openings being a maximum of 2% of the total area of the upper side of the cover hood or decorative panel.
  • a further advantageous embodiment of the invention provides that the flange has a multiplicity of projections, the spacers engaging in recesses delimited by the projections.
  • the inlet surface is delimited to the outside by a circumferential shoulder or a circumferential inner wall, the shoulder or the wall having a plurality of projections, and the spacers engaging in recesses delimited by the projections.
  • This form-fitting connection prevents or blocks rotation of the cover around a vertical axis relative to the flange and the drain housing.
  • Another advantageous embodiment of the invention is characterized in that an annular shoulder is formed on the inlet surface for positively receiving a flange section of a fastening flange, in particular a screw flange.
  • the transition from the inlet surface to the fastening or screw flange can be made essentially flush with the surface, preferably without an upwardly protruding projection. In this way, deposits at the transition from the inlet surface to the screw flange can be largely prevented.
  • the inlet surface surrounding the inlet opening of the drain housing is connected to the drain housing by means of a screw flange.
  • This configuration enables the number of components of the drain fitting to be reduced by using only a single screw flange instead of a fastening flange with several fastening screws and a corresponding number of threaded sleeves cast in the drain housing, which is screwed into an internal thread formed on the inlet opening of the drain housing.
  • the screw flange preferably has grip elements.
  • the screw flange can thus be screwed into the internal thread formed on the inlet opening of the drain housing without tools.
