Definitions

  • the invention relates to a walk-in shower.
  • Walk-in showers are commonly known. There are various embodiments, such as e.g. a stall shower with a ceramic or metal tub and with metal or plastic side walls and a glass door, or a walk-in shower with a tiled floor without a step, a tiled wall, two glass side walls and a glass door.
  • Walk-in showers have the advantage that the installation thereof requires less consideration for the height of the final floor below or around the shower, and that they can be installed e.g. after the bathroom has been tiled, or that they can be installed afterwards without breaking up the floor, but they have the disadvantage of a step of e.g. 20 cm, which is a problem for older people.
  • Walk-in showers avoid such a step, and usually have a floor with the same tiles as used around the walk-in shower, which is aesthetically very attractive, hence their increasing popularity in recent years.
  • One problem with such walk-in showers is that they often exhibit moisture problems, such as leakage and/or mould formation.
  • the shower according to the present invention comprises:
  • the walk-in shower has a water-impermeable upright wall (e.g. at a side face or at the back), seeping of water through the side wall or back wall is avoided.
  • the walk-in shower is provided with tiles along the side (or back). These upright tiles can abut the walls in an aesthetically beautiful way.
  • the second plate is a water-permeable plate, such that moisture situated behind the upright tiles, or in the joints between the tiles, may dry up quicker, such that mould formation and/or growth is prevented, or at least heavily reduced.
  • the second spacers are elongated second support ribs for mounting the second plate, and for guiding the shower water behind the second plate in the direction of the tub, and for forming second circulation channels for the air circulation behind the second plate.
  • the second support ribs are an integral part of the water-impermeable upright wall, such that the installation time of the walk-in shower is greatly reduced and the finishing is improved.
  • the impermeable upright wall and the second plate are connected by means of a second hinged connection for tilting the second plate for cleaning the second cavity.
  • the second cavity is more accessible, and can (if desired) even be opened completely to promote drying.
  • the tub has first spacers, mounted on the bottom, for supporting a first plate at a distance above the bottom to form a first cavity between the bottom and the first plate; wherein the first plate has a circumference with outer dimensions that are smaller than the inner dimensions of the raised edge of the tub to form a gutter along at least a portion of the circumference, for drainage of the shower water and for allowing air circulation below the first plate; and wherein the first plate is at least partially covered with tiles.
  • the walk-in shower in this embodiment has a water-impermeable tub at the bottom for collecting the shower water, seepage of water through the floor (and possibly the ceiling below) is avoided.
  • a walk-in shower never uses a tub; foils and the like are used, of which it is the intention that they are connected watertight to each other and to the drain opening, but they are often not watertight.
  • the walk-in shower is provided on its bottom with tiles on which one can stand. These laying tiles can abut in an aesthetically beautiful way the tiles around the shower (except for the gutter).
  • first plate By positioning the first plate at a distance above the bottom of the tub, and by choosing the outer dimensions of the first plate to be smaller than the inner dimensions of the raised edge of the tub, a first cavity is created below the first plate, and a gutter is created along the circumference of the first plate such that air circulation is possible in the first cavity below the first plate via the gutter. Due to this air circulation, the possibly remaining shower water will evaporate in the first cavity below the first plate, such that mould formation below and between the laying tiles is avoided.
  • the first plate is a water-permeable plate, such that moisture that is situated below the laying tiles, or in the joints between the tiles, can dry up faster (e.g. order of magnitude of several hours), such that mould formation and/or growth is prevented, or at least greatly reduced.
  • the first plate has a convex shape for the drainage of the shower water to the gutter, for example a substantially spherical shape.
  • a convex shape for the drainage of the shower water to the gutter for example a substantially spherical shape.
  • the first spacers are elongated first support ribs for supporting the first plate, for guiding the shower water in the direction of the drain opening, and for forming the first circulation channels for the air circulation below the first plate.
  • the first support ribs are for example an integral part of the water-impermeable tub, such that the assembly time of the shower is greatly reduced and the finishing is improved.
  • the first support ribs have rounded edges for avoiding corners in which soap residues or other dirt can accumulate. Avoiding remaining soap residues that may prevent an easy drainage contributes to avoiding moisture problems.
  • the tub can be cleaned faster, easier and more thoroughly, contributing to the hygiene in the bathroom.
  • the tub and the first plate are connected by means of a first hinged connection for tilting the first plate for cleaning the first cavity.
  • first hinged connection for tilting the first plate for cleaning the first cavity.
  • the first plate consists of two sections, each of which are connected to the tub by means of a hinged connection, for tilting the sections. In this way, one can stand on one section during cleaning of the other opened section.
  • the invention also focuses on the water-impermeable tub with a bottom and an edge and with first supporting ribs, as an element of the above-described walk-in shower.
  • the invention is also directed to the water-impermeable wall with second support ribs, as an element of the above described walk-in shower.
  • Fig 1 shows a portion of an embodiment of a walk-in shower 30 according to the present invention in perspective view and from a distance. Visible are tiles 5a at the bottom of the walk-in shower 30 on which a person can stand, and tiles 5d against at least one upright wall are provided, in this example on the back wall.
  • the sides of the walk-in shower 30 may be open, or may e.g. be two transparent side walls, and may e.g. be made of a plastic material or of glass or Plexiglas, or any other material deemed suitable by a person skilled in the art.
  • a walk-in shower 30 according to the invention may also contain more than one tiled side wall, e.g. two or three.
  • the walk-in shower 30 also has an entrance door, for example made from glass.
  • the walk-in shower 30 has a water-impermeable tub 1 which is generally incorporated in the top floor (also known as "screed"), as shown in Fig 4.
  • Fig 4 shows the tub 1 of Fig 1 in cross section along section line C-C.
  • the dimensions of the walk-in shower 30 may be selected such that the top of the tiles 5a on the first plate 4 lie at substantially the same height as the tiles 5c next to the walk-in shower.
  • the floor tiles 5b may be placed at a short distance (e.g. 1 m) from the walk-in shower 30 at a small decline, e.g. a decline of 1-3 cm over a distance of 1 m in length, to direct the shower water that falls next to the tub back to the tub 1.
  • the tiles 5b are for example placed up to the edge 16 of the tub, such that shower water that falls on the tiles 5b flows into the tub 1, and not next to the tub, to avoid moisture problems.
  • Fig 2A shows an embodiment of a tub 1 according to the invention in top view, and also indicates the position of the first plate 3, wherein a portion of the first plate has been cut away for illustrative purposes.
  • Fig 2B shows the tub in cross section along section line A-A
  • Fig 2C shows the tub in cross section along section line B-B.
  • the figures 2A-2C show a water-impermeable tub 1 with a bottom 15 and an raised edge (or border) 16.
  • the bottom 15 exhibits a slope towards a drain opening 2 for the drainage of the shower water.
  • the slope angle ⁇ is typically 1-3 degrees.
  • the tub 1 has first spacers 3, located on or applied to the bottom 1 for supporting a first plate 4 at a distance (of e.g.
  • the first spacers 3 are at least two elongated first support ribs by which the first plate 4 can be supported.
  • the first support ribs 3 are an integral part of the tub 1, and are for example formed together during the manufacture of the tub. This also provides a better finishing, less work to install the walk-in shower, and an increased hygiene.
  • the tub of Fig 2A has three substantially parallel first support ribs 3, with rounded edges to avoid remaining soap residues, and to ease the cleaning process. (Corners are indeed difficult to clean).
  • a rubber strip (not shown) may be applied to the first supporting ribs 3, by which the first plate 4 can be supported.
  • the portion of the first support ribs by which the first plate 4 will be supported will for example be placed substantially level.
  • the drain opening 2 in the tub of Fig 2 is located in the middle of one side of the tub 1, and the first support ribs 3 run substantially parallel in the direction of the drain opening 2, however other topologies are also possible.
  • the drain opening may also be located in one of the corners of the tub, or substantially in the middle of the tub, wherein for example each of the first support ribs 3 is positioned in such a way that their carriers (or extensions thereof) intersect in a point substantially in the drain opening 2. In this way, the first support ribs 3 help to guide the shower water to the drain opening 2.
  • the first plate 4 is for example rectangular or square, but other shapes are also possible.
  • the outer dimensions w, y of the first plate 4 are smaller, e.g. 1 to 10 cm smaller, for example 2 to 8 cm, or 2 to 6 cm smaller than the inner dimensions W, Y of the edge 16 of the tub 1, such that an opening is created (between the first plate 4 and the edge 16), which acts as a gutter 8 along at least a portion of the circumference of the first plate 4.
  • the shower water that falls on the tiled first plate 4 is directed to the drain opening 2.
  • This opening or gutter 8 also allows air circulation in the first cavity 7 below the first plate 4, for evaporation of the shower water that is not drained away, and for evaporation of the moisture that has seeped in between and under the tiles 5a of the first plate 4.
  • Figure 3 is a cross section of the walk-in shower along section line D-D of Fig 1.
  • Fig 3 and Fig 4 show that the embodiment of the walk-in shower 30 according to the invention has at least one water-impermeable upright wall 20, on which second spacers 13 are attached.
  • these are at least two elongated second support ribs 13 which are positioned upright, for example vertical. This has the advantage that seepage water is drained quickly.
  • the second spacers 13 are part of the water-impermeable upright wall 20, and are for example formed at the same time during the manufacture of the wall 20.
  • the second spacers 13 show rounded corners where joining the impermeable wall 20 because of the same advantages as mentioned for the first support ribs 3 and the tub 1.
  • a second plate 14 is mounted, at a distance from the impermeable upright wall 20 to form a second cavity 17.
  • the second plate 14 of Fig 4 is rectangular, and a bottom and a top thereof are provided with openings 18 (e.g. a bottom and a top slit) for allowing air circulation through the second cavity 17.
  • the second plate 14 is at least partially covered with tiles 5d.
  • the elongated second support ribs thus have the following functions: fixing the second plate 14 suspended above the tub 1, guiding the shower water behind the second plate 14 in the direction of the tub 1, and forming second circulation channels for the air circulation behind the second plate 14.
  • the water-impermeable plate 20 may occupy the entire height of the space, or it may occupy a portion thereof as shown in the example of Fig 4 . In that case, the opening 18 at the top of the second plate 14 will not be located against the ceiling of the bathroom, but a lower distance. Over this distance then e.g. tiles 5e can be applied to the wall 11 (or to the stucco).
  • the upright impermeable wall 20 with the second support ribs 13 is for example positioned in such a way with respect to the second plate 14, that shower water that flows down along the upright tiles 5d, for example ends up directly in the gutter 8.
  • this shower water is guided to the drain opening 2, and in this way takes with it as much as possible of the shower water and soap residues or other dirt.
  • the first plate 4 has a convex shape for the drainage of the shower water that falls on the first plate 4 to the gutter 8, for example a substantially spherical shape, with the highest point at substantially the centre of the first plate 3. Because of this, it can be avoided that the first plate 4 itself has to be placed at an angle, which makes it difficult to stand on. Because of this, it is also possible to position the circumference of the first plate 4 is substantially level, which greatly simplifies the tiling along the tub 1 (and on the edge 16). By using the tub 1 and the first plate 4 with a convex shape, the drainage does not have to be worked out in the floor tiles 5a, as is the case in known embodiments of walk-in showers. In this way, a lot of time can be gained during the assembly of the walk-in shower.
  • the first and the second plate 4, 14 are made of a porous material, and are thus water-permeable. This not only promotes drying of the fluid behind/below/in between the tiles 5, but also the adhesion of the tiles 5 to the first and second plate (because of the improved adhesion in the pores of the first resp. second plate).
  • a suitable material is a fibre cement board.
  • the tub 1 and the water-impermeable wall 20 are made of a plastic material, e.g. an acrylic. But other materials may also be used, e.g. an aluminium plate of which at least one side is coated with plastic. The aluminium plate provides the strength, the coating provides the contact medium with the shower water.
  • the first plate 4 can be removably attached.
  • the first plate 4 is attached to the tub 1 by means of a first hinged connection (not shown), such that it can be tilted for cleaning the first cavity 7 below the first plate 4.
  • a hydraulic pump or an air pump may be provided to help the first plate 4 to tilt against the weight of the first plate 4.
  • a locking mechanism ensures that the first plate 4 remains in a flat position during normal use of the walk-in shower 30.
  • the second plate 14 can be permanently mounted to the second support ribs 14 by means of adhesive, but the second plate may also be removably attached e.g. by means of a second hinged connection (not shown) for rotation of the second plate 14 for cleaning of the second cavity 17.
  • a second hinged connection (not shown) for rotation of the second plate 14 for cleaning of the second cavity 17.
  • rust free hinged connections are used, e.g. from plastic or from stainless steel or aluminium.
  • the first plate 4 consists of two parts, e.g. from two substantially equal halves, wherein both halves are connected to the tub 1 by means of hinged connections, such that they can both at the same time or separately be opened outwardly. This allows e.g. to stand on one part while the other part is opened during the cleaning process.
  • lighting may also be provided below the first plate 4, e.g. LED lighting, or lighting on the basis of an optical fibre.
  • the light will then be visible through the gutter 8 between the edge 16 of the tub 1 and the tiled first plate 4. This is both aesthetically pleasing and practical, because the light indicates the area where the person who wants to shower, should stand most appropriately.
