Definitions

  • the invention relates to a shower tray device according to the preamble of claim 1, as well as to a floor in which such a shower tray device is integrated, and to a method for installing a shower tray device in a floor.
  • a shower floor is required, providing a surface on which a person can stand while showering and through which shower water can drain.
  • a shower tray For many decades, it has been known to create such a shower floor using a shower tray. While shower trays were originally designed like bathtubs, featuring a horizontal base with a drain opening and vertical walls extending upwards from it, typically with a height of 20 to 30 cm, shower trays have recently become increasingly shallower. In modern shower trays, the bathtub shape is only subtly suggested, and the walls extend only a few centimeters. The shallower design of modern shower trays not only creates a contemporary look for the shower but also makes it easier to enter the shower. However, there are technical limitations to the minimum installation height of shower trays, as...
  • shower trays have a considerable horizontal dimension, typically at least 80 cm x 100 cm or at least 90 cm x 90 cm, and should be as rigid as possible across their horizontal extent when walked upon. Robust support against the subfloor on which they are installed is also required, necessitating a vertically thick overall structure and a stabilizing contour of the shower tray or its support, particularly in the support area. Therefore, special precautions must be taken when using a conventional shower tray to create a level-access shower floor.
  • the shower tray is usually installed as part of a shower tray unit that includes a support on which the tray is mounted.
  • the support structure is typically installed on a subfloor, after which a load-bearing layer, usually and preferably a screed (though it can also be achieved with a combination of wooden elements and leveling compound), is applied around the support structure.
  • a load-bearing layer usually and preferably a screed (though it can also be achieved with a combination of wooden elements and leveling compound)
  • This layer projects vertically beyond the support structure by the same amount as the shower tray extends beyond it.
  • this procedure is complex and prone to errors due to the interlocking of different trades, as the top surface of the load-bearing layer must project vertically beyond the support structure with a precisely planned offset.
  • the shower tray's top surface is positioned next to the top surface of the load-bearing layer, there is an increased risk of water penetrating between the shower tray and the load-bearing layer and spreading onto the floor.
  • a drainage channel is incorporated into the subfloor.
  • the subfloor is designed with a slope towards the drainage channel, allowing it to be subsequently covered with a conventional floor covering, such as floor tiles, vinyl planks, a poured or laid plastic floor covering (e.g., epoxy resin flooring), or a cement-based covering, extending up to the drainage channel.
  • EP 3 815 591 A1 A shower tray device is disclosed, comprising a shower tray which can be arranged on a subfloor supported by a support frame and which has a drain section with a drain opening as well as a support area arranged outside the drain section, with which it can be placed on the support frame or on a supporting surface.
  • the present invention is based on the objective of providing a shower tray device, a floor comprising such a shower tray device and/or a method for installing a shower tray device in a floor, with which at least one disadvantage is at least partially eliminated that exists in conventional manufacturing techniques for a shower floor.
  • the invention proposes a shower tray device with the features according to claim 1.
  • the shower tray assembly comprises a base element.
  • the base element extends along a horizontal plane in a horizontal longitudinal direction with a length of at least 60 cm, particularly at least 80 cm, and in a horizontal transverse direction with a width of at least 60 cm, particularly at least 80 cm.
  • the longitudinal and transverse directions are perpendicular to each other and span the horizontal plane.
  • the base element has a width of at least 80 cm and a length of at least 100 cm, particularly at least 120 cm. More preferably, the base element has a width of at least 90 cm, particularly at least 100 cm, and a length of at least 90 cm, particularly at least 100 cm.
  • the base element has a width of at least 80 cm, particularly at least 90 cm, particularly at least 100 cm, and a length of at least 120 cm, particularly at least 140 cm.
  • the base element has a drain opening within its horizontal extension.
  • the drainage opening extends vertically through the base element, from its vertical top to its vertical bottom. Drainage opening allows access to the top of the Water that enters the base element is discharged downwards beneath it.
  • the drainage opening is located entirely within a horizontal drainage section of the base element, which constitutes a substantial portion of the base element's horizontal extent.
  • this section comprises at least 10%, and more preferably at least...
  • the drainage section comprises 20%, preferably at least 30%, of the horizontal extent of the base element and/or extends horizontally over at least 400 cm2 , in particular at least 600 cm2 , and in particular at least 1000 cm2 , thus forming a correspondingly planar horizontal extent of the base element.
  • the drainage section forms a continuous, closed rim surrounding the drainage opening. More preferably, the drainage section extends in all horizontal directions at least 3 cm, and in particular at least 5 cm, away from the rim surrounding the drainage opening, so that it forms a solid section surrounding the drainage opening with a corresponding horizontal extent, within which, for example, a drainage pot, as described in more detail below, can be arranged on the underside of the base element to seal around the drainage opening.
  • the drainage section forms the support surface of the base element, described in more detail below, horizontally outside the drainage opening.
  • the base element is preferably designed as a plate, the surfaces of which form the top and bottom of the base element, and whose narrow sides run vertically and connect the surfaces.
  • the base element is designed as a plate made of solid material, i.e., the plate volume is filled by the solid material.
  • the solid material can be, for example, a mineral casting or a polyurethane foam.
  • the base element has a vertical thickness of at most 20 mm, in particular at most 15 mm, at least at a first longitudinal end over its entire transverse extent and at a first transverse end over its entire longitudinal extent. In particular, less than 13 mm, in particular less than 12 mm, in particular less than 11 mm. In an embodiment that can be combined particularly advantageously with the aforementioned, the base element has a vertical thickness of at least 5 mm, in particular at least 10 mm, at least at a first longitudinal end over its entire transverse extent and at a first transverse end over its entire longitudinal extent.
  • the first longitudinal end defines an absolute end of the base element with respect to the longitudinal direction
  • the first transverse end defines an absolute end of the base element with respect to the transverse direction.
  • the floor element also has a correspondingly low vertical thickness at its second transverse end, opposite the first transverse end in the transverse direction, along its entire longitudinal extent. This makes it possible to integrate the floor element at both of its transverse ends and at the first transverse end into such a floor covering adjacent to the rest of the floor covering.
  • the floor element also has a correspondingly low vertical thickness at its second longitudinal end, opposite the first in the longitudinal direction, along its entire transverse extent.
  • the floor element has a correspondingly small vertical thickness, allowing it to be integrated into a floor covering even when spaced away from a wall.
  • the floor element has the same vertical thickness at its first longitudinal end as at its first transverse end, and especially at its second transverse end and its second longitudinal end.
  • the maximum thickness at each longitudinal end is defined as the maximum thickness at each transverse end.
  • the floor element has a slope of at least 0.7%, particularly at least 1%, particularly at least 1.2% towards the drain opening over an area of at least 0.3 m2 , particularly at least 0.5 m2 , and particularly over at least 70%, particularly at least 80% of the total surface area of its upper surface.
  • the slope is formed over an area of the upper surface that comprises at least 70%, particularly at least 80%, of the total horizontal extent of the floor element.
  • the base element further comprises a bearing area that extends horizontally outside the drain section and from the first longitudinal end of the base element over at least 30%, in particular at least 40%, and in particular at least 50%, and in particular at least 60%, of the length of the base element extends longitudinally towards the drain opening across the entire width of the base element.
  • the support area lies completely outside the drain section horizontally.
  • the base element consists of the drain section and the support area.
  • the support area is designed to rest on the upper surface of a screed laid on the subfloor, which is arranged horizontally next to the drain section and runs parallel to the horizontal plane.
  • the support area is also preferably designed to rest on the upper surface of any other load-bearing layer arranged horizontally next to the drain section on a subfloor and which has an upper surface running parallel to the horizontal plane.
  • a side-by-side arrangement includes, in particular, an arrangement directly adjacent to one another, unless otherwise specified.
  • the floor element rests on the described upper surface of the described supporting surface over its entire bearing area.
  • a space provided horizontally between the subfloor and the underside of the drainage section, adjacent to the load-bearing surface and the bearing area, can be used to accommodate a drainage pot, which is then sealed around the drainage opening within the drainage section and connected to the underside of the floor element.
  • the drain opening is particularly preferably spaced at least 15%, particularly at least 20%, particularly at least 30%, and particularly at least 40% away from at least one transverse end of the floor element, and especially at least from the first transverse end of the floor element. This is particularly preferably true for each transverse end, and thus not only for the first transverse end but also for the second transverse end opposite the first transverse end in the transverse direction, wherein the transverse ends define the floor element in the transverse direction.
  • Such a spacing from the respective transverse end is particularly advantageous if, in the operating state, the floor element extends in the transverse direction over at least 5%, particularly at least 10% of its total transverse extent with its bearing area extending from the respective transverse end towards the drain opening and/or extends in the transverse direction beyond a support described in more detail below.
  • the inventors have surprisingly discovered that spacing the drain opening from the respective horizontal end of the base element can significantly contribute to the stability of the base element. It should be noted that, due to the spacing of the drain section from the first longitudinal end, the drain opening is already considerably spaced before reaching the first longitudinal end.
  • the thickness of the floor element would decrease with increasing distance from the longitudinal end, where it already has a small thickness, to such an extent that sufficient stability of the floor element could no longer be guaranteed.
  • the invention overcomes this misconception by simultaneously providing a sufficiently large bearing area encompassed by the floor element for resting on a screed or other load-bearing surface, and by providing a drainage section encompassed by the floor element in addition to the bearing area. Since the drainage section If the floor element is located next to the support area and is therefore not intended to rest on the supporting surface, it can have a geometry within the drainage section that is decoupled from the support requirement on the supporting surface, for example, a greater thickness than within the support area.
  • a further advantage of the shower tray installation according to the invention is that it opens up new design possibilities for the floor element and can provide a different spatial experience for a person stepping onto it. Because the floor element can bear a large area of support on the substrate, a void effect, which often occurs with conventional shower trays, can be avoided. This makes stepping onto the floor element very similar to stepping onto a tile or other floor covering laid on the substrate, resulting in a high-quality feel underfoot.
  • the shower tray installation according to the invention the The floor element is designed like a tile and perceived by the user as part of the tiled surface.
  • the base of the support is located exclusively outside the horizontal extent of the bearing area in the operating state, or exclusively horizontally outside and thus next to the load-bearing surface.
  • the support is designed to be supported by resting on the screed or other load-bearing surface on the subfloor, or to be erected on the subfloor in this way.
  • the support can, for example, have a plate-like support section for placement on the screed or other load-bearing surface and a retaining section offset horizontally from the support section to support the floor element outside the load-bearing surface.
  • the support section has a thickness of less than 3 mm, particularly less than 2 mm, so that it can be easily integrated into a tile adhesive layer and no excessively large corresponding recess needs to be provided on the underside of the floor element, which would entail a corresponding reduction in the thickness of the floor element.
  • the support extends In its intended use, the shower tray assembly extends vertically from the subfloor to the support surface of the base element, wherein the support may include a base that is placed directly on the subfloor.
  • the support surface and the bearing surface are preferably congruent and thus preferably lie completely against each other in the operating state.
  • the bearing area lies horizontally outside the support surface and thus, in the operating state of the shower tray assembly, outside the horizontal area of the shower tray assembly in which the support surface rests against the base element to support the base element as intended on a subfloor on which it rests.
  • the support bears at least a portion of the weight force exerted vertically by the base element towards the subfloor and, correspondingly, also at least a portion of the weight force of a person standing on the base element during intended use of the shower tray assembly.
  • the support is designed to transfer a vertical weight force of at least 200 N from the support surface to the base without deformation, through the interaction of the load-bearing surface and the bearing surface, so that it can hold a corresponding weight resting on its load-bearing surface above a subfloor on which it rests.
  • the bearing area is preferably arranged horizontally completely outside the support, or at least completely outside the bearing surface and the bearing surface.
  • it is supported on the upper side of a screed or other material provided on the subfloor, which is arranged horizontally next to the support and runs parallel to the horizontal plane.
  • the floor element is designed with a supporting surface and the support itself resting on the subfloor.
  • the floor element is thus supported on the subfloor via the supporting surface, particularly the screed, and supported on the subfloor via the support itself. Thanks to its suitability as described above, it can also be used in applications where the supporting surface rests on a mounting frame, which in turn rests on the subfloor. In the operating state of the shower tray unit, this mounting frame is positioned horizontally next to the support, with its upper surface, on which the supporting surface rests, running parallel to the horizontal plane.
  • the support can also be designed to support the floor element on its own, without the floor element needing to rest on the supporting surface.
  • the support area is designed, in particular, to provide support on the upper surface of the support surface or the upper surface of the mounting frame when the shower tray is in operation and the upper surface of the support surface or mounting frame is directly adjacent to the support.
  • the support area is preferably designed to be supported on the upper surface of the support surface or mounting frame, which is vertically at the same height as at least a section of the support surface, and in particular the entire support surface of the support.
  • the inventors have recognized that providing a flat, large-area floor element is particularly advantageous, as it has a large horizontal support area that rests on the upper surface of a support surface running parallel to the horizontal plane.
