Description

The invention relates to a drain comprising a collecting tray with a bottom, an upright peripheral wall arranged along the periphery of the bottom, which peripheral wall bounds an inflow opening, and a discharge opening for discharging collected water;
wherein the peripheral wall of the collecting tray consists of two parts so as to be height-adjustable; and
wherein the peripheral wall comprises a first peripheral wall part, which first peripheral wall part is upright along the periphery of the bottom and is arranged thereon, and wherein the peripheral wall comprises a second peripheral wall part which is displaceable relative to the first peripheral wall part in a direction perpendicularly of the bottom. Such a drain is for instance known from EP 2140072 .
Drains are usually placed in the centre of a floor, after which a tile floor is laid around the drain and, finally, a seal, such as a silicone mastic bead, is arranged between the peripheral wall of the collecting tray of the drain and the surrounding tiles.
In the case of elongate drains it is more usual to place them against a wall so that the tile floor to be laid requires only a single slope. Because the drain lies against a wall in these cases, it is more difficult to provide a good seal between the collecting tray and the wall, which increases the chance of leakages.
In the shower drain according to EP 1287213 an upright plate is provided on one side, with which the drain can be mounted against a wall. Because the plate is formed integrally with the collecting tray, this upright plate, on which a sealing membrane can be arranged, provides for a reliable seal in the transition from wall to floor and drain. The drawback of this solution is that a special model, specifically for such wall applications, must be kept in stock. This shower drain cannot for instance be applied in the centre of a floor.
It is further known, for instance from EP 2140072 , to use an adjusting frame in elongate drains, which frame surrounds the inflow opening of the drain and thereby provides a finish for the side of the surrounding tiles. The adjusting frame here usually lies against the peripheral wall which is upright from the bottom. Depending on the application and wishes, it is necessary to arrange a seal between the adjusting frame and this upright peripheral wall, which is usually a silicone sealant or the like. When the drain is placed against a wall, it is difficult to reach between the adjusting frame and the peripheral wall with a mastic gun.
In the case of such adjusting frames it is moreover known to provide a horizontal flange on the side adjacent to the wall, so that the gap between the adjusting frame and the wall tiles can be bridged. The horizontal flange however does impede the option of arranging a seal after the adjusting frame has been arranged. In the case of such a known adjusting frame it is thereby necessary to first arrange the seal, such as a sealant, and then place the adjusting frame, in hopes that the adjusting frame will be sealed to sufficient extent by the already arranged sealant. A visual inspection hereof is however not possible due to the horizontal flange on the frame.
When a shower drain with a horizontal flange arranged therearound is used and placed against a wall, the width of the horizontal flange will ensure that the inflow opening comes to lie at a distance from the wall. This is because the flange is usually for instance more than 2 centimetres wide in order to provide a sufficient attaching surface for a tile membrane, while wall tiles are usually no thicker than 1 centimetre. This will result in a gap of at least 1 centimetre between the wall tiles and the inflow opening of the shower drain, which for instance has to be filled with a specially cut tile strip.
The inflow opening of a drain is understood to mean the opening along which the majority of the water to be discharged flows into the drain. In some drains a secondary drainage is further provided, this having small individual openings along which small quantities of leaked water, for instance coming from under a tile layer, can still flow into the drain. Such openings for secondary drainage are not deemed to be the inflow opening of a drain in the present invention.
It is now an object of the invention to provide a drain wherein the above stated drawbacks are reduced or even obviated.
This object is achieved according to the invention with a drain according to the preamble, which is characterized by an elongate profile with substantially constant cross-section, which profile is arranged parallel to and adjacently of a side of the peripheral wall and wherein the centre of gravity of the cross-section of the profile lies outside the inflow opening, as seen in top view of the drain.
The drain according to the invention is very suitable to be placed against a wall. The necessary sealing can then be provided and, finally, an elongate profile is placed adjacently of a side of a peripheral wall. This profile can provide the connection of the drain to the wall so that a seal need not immediately be arranged in the corner where the wall, floor and drain meet.
Because the centre of gravity of the cross-section of the profile lies outside the inflow opening, the profile will extend substantially outside the inflow opening, whereby it can provide a bridging between the inflow opening and for instance a wall.
It is possible to provide such elongate profiles along more sides of the peripheral wall, for instance when the drain is placed in the corner against two walls at right angles to each other.
The use of a separate profile enables the colour and material of the profile to be chosen as desired. It is thus for instance possible to have the colour of the profile match the colour of the wall tiles. The profile can for instance be made from stainless steel, although a plastic, such as corian, is also possible.
The two-part form of the peripheral wall is also often referred to as a collecting tray with single peripheral wall, in which an adjusting frame or tile frame is arranged. This adjusting frame or tile frame lies directly adjacently of or even against the upright peripheral wall and is height-adjustable by means of adjusting means. The height of the upper edge of the peripheral wall can hereby be adjusted to the thickness of the surrounding tiles or finishing layer.
An additional advantage of the invention is that the two-part peripheral wall can be easily sealed with a sealant layer. The seal can then still be visually inspected, only after which the elongate profile is arranged on the upper edge of the two-part peripheral wall and a good connection to an adjacent wall can thus be obtained.
In a preferred embodiment of the drain according to the invention the elongate profile comprises a depending wall part, which wall part extends via the inflow opening on the inner side of the peripheral wall or in a longitudinal groove in the upper edge of the side of the peripheral wall.
When moisture comes to lie on the profile, it will automatically flow via the profile and the depending wall part into the inflow opening. It is thus for instance possible to attach a sealing membrane, such as a tile membrane, to the profile and to incorporate this membrane behind a finishing layer, such as a tile layer. If a crack were to appear in the tile-work, leakage water will flow via the sealing membrane, over the profile and into the inflow opening, whereby leakage cannot occur.
In a further preferred embodiment of the drain according to the invention the elongate profile comprises a horizontal wall part extending from the upper edge of the side of the peripheral wall and away from the inflow opening.
In addition, the elongate profile preferably comprises a vertical, upright wall part which is arranged on the distal end of the horizontal wall part, as seen in cross-section.
With such a profile, which has substantially an L-shaped cross-section, the distance from the upright wall of the collecting tray to the wall of a space can be bridged, and with the vertical part a flange is moreover provided to which a sealing membrane, such as a tile membrane, can be easily attached.
The vertical part can also be used as visible part. It is hereby possible with the vertical part to compensate for a height difference between a shower floor zone and a surrounding bathroom floor, whereby wall tiles adjacent to the bathroom floor can run in a horizontal path to the shower floor zone without interruption. The height difference between this horizontal tile path and the shower floor which lies lower is compensated by the vertical visible part of the profile.
Yet another embodiment of the drain according to the invention further comprises a filler body, such as a foam body, arranged on the underside of the horizontal wall part.
Since an upright wall of the collecting tray often also provides for the bounding of surrounding tiles, and because a tile edge is usually no longer placed behind a drain which is placed against the wall, there will be a height difference between the sub-floor and the horizontal wall part of the profile. The foam part fills this space and moreover easily compensates possible height differences.
In addition, a groove into which a side of the peripheral wall can be inserted can be formed in simple manner using the foam part and the depending wall part, so that the profile can be easily coupled to the peripheral wall.
Yet another embodiment of the drain further comprises a horizontal peripheral flange arranged on the outer side of the collecting tray.
A water-sealing membrane can be attached to the peripheral flange for the purpose of sealing the drain relative to a sub-floor, while the elongate profile can be arranged on the upper edge of the upright peripheral wall for the purpose of a reliable sealing on an adjacent wall of a space.
The invention further relates to a combination of a drain according to the invention with a two-part peripheral wall and a sub-floor, wherein the collecting tray is at least partially embedded in the sub-floor, wherein the combination further comprises a seal, such as a silicone mastic bead, arranged between the two parts of the upright peripheral wall.
The invention also relates to a method for arranging a drain according to the invention in a sub-floor, which method comprises the steps of:

providing a drain according to the invention;
positioning the collecting tray on a ground;
pouring a sub-floor around the collecting tray, such that the collecting tray is at least partially embedded in the poured sub-floor;
arranging a seal between the two parts of the upright peripheral wall of the collecting tray;
arranging the elongate profile on the upper edge of a side of the peripheral wall after the seal has been arranged, wherein the elongate profile extends over the upper surface of the sub-floor.

In yet another embodiment of the drain according to the invention the second peripheral wall part is formed integrally with the first peripheral wall part.
For some applications a height adjustment of the peripheral wall part is not required, while a separately arranged elongate profile is conversely desired on the peripheral wall part in order to for instance bridge the distance between the peripheral wall and an adjacent wall.
These and other features of the invention are further elucidated with reference to the accompanying drawings.

Figure 7 shows a cross-section of a sixth embodiment according to the invention.
Figure 8 shows a cross-section of a seventh embodiment according to the invention.

Figure 1 shows a first embodiment 1 of a drain according to the invention. Drain 1 has a collecting tray with a bottom 2 (see also figure 2) and a two-part peripheral wall 3, 4. First peripheral wall part 3 is here arranged on bottom 2 as one whole, while the second peripheral wall part 4 is embodied as adjusting frame. Second peripheral wall part 4 can be adjusted in the height by means of adjusting screws 5 so that upper edge 6 of peripheral wall part 4 can be brought to the same height as a surrounding floor, such as a tile floor.
Collecting tray 2, 3, 4 is further provided with an outflow 7 so that water flowing in via inflow opening 8, which is bounded by peripheral wall part 4, and is collected in collecting tray 2, 3, 4 can be discharged.
First peripheral wall part 3 is further provided with a horizontal flange 9 to which for instance a water-sealing membrane can be attached.
An elongate profile 10 is arranged on upper edge 6 along one side. This elongate profile 10 has in cross-section a horizontal wall part 11, a depending wall part 12 hanging over upper edge 6 into inflow opening 8 and a vertical wall part 13 arranged on the distal end of horizontal wall part 11. A filler body 14 of a foam is arranged under horizontal wall part 11.
The centre of gravity Z of the cross-section of elongate profile 10 lies outside inflow opening 8, as seen in top view of drain 1.
Figure 3 shows a second embodiment 20 of a drain according to the invention. This drain 20 has a collecting tray with a bottom 21, a single upright peripheral wall 22 and an outflow 23. Peripheral wall 22 here also bounds an inflow opening 24.
Arranged on an upper edge 25 of peripheral wall 22 is an elongate profile 26 with a substantially L-shaped cross-section. Arranged under profile 26 is a filler body 27 whereby L-shaped profile 26 supports partially on sub-floor 28.
As shown in figure 3, collecting tray 21, 22, 23 is partially embedded in sub-floor 28 and L-shaped profile 26 lies with the vertical part against a wall 29. Sub-floor 28 is tiled with tiles 30, while wall 29 is also provided with tiles 31, which cover the vertical part of L-shaped profile 26.
The embodiment according to figures 1 and 2 can also be built into a sub-floor and against a wall in the same manner. The advantage of a separate elongate profile 11, 12, 13; 26 is that use can be made of a collecting tray 2, 3, 4; 21, 22, which is also suitable for installation in the centre of a space. Separate profile 11, 12, 13; 26 can be installed at a later time than collecting tray 2, 3, 4; 21, 22 is embedded in the sub-floor, whereby seals can also be provided more easily.
Figure 4 shows a third embodiment 40 of a drain according to the invention. Drain 40 has a collecting tray with a bottom 41, a peripheral wall 42 and an outflow 43. Peripheral wall 42 bounds an inflow opening 44 of collecting tray 41, 42, 43.
Arranged in the upper edge of peripheral wall 42 is a slot 45 into which a depending wall part 46 of an elongate profile 46, 47, 48 can be inserted. Because wall part 46 protrudes into the slot 45, the height of elongate profile 46, 47, 48 relative to collecting tray 41, 42, 43 is adjustable. This embodiment 40 can also be arranged in a sub-floor and close to a wall in the same manner as shown in figure 3.
Figure 5 shows a fourth embodiment 50 of a drain according to the invention. Drain 50 has a collecting tray with a bottom 51, an upright first peripheral wall part 52 on which a horizontal flange 53 is arranged and a second peripheral wall part 54 which is height-adjustable.
A U-shaped profile 55 is arranged on the upper edge of second peripheral wall part 54 along one side. A glass plate 56 is placed in this U-shaped profile 55.
The advantage of the invention is that collecting tray 51, 52, 53, 54 can be embedded in sub-floor 57 in this embodiment. The second peripheral wall part 54 is then adjusted in the height so that upper edge 58 lies at the same height as the upper surface of floor tiles 59. Finally, the U-shaped profile 55 can be placed, in which the glass plate 56 can be arranged.
Because U-shaped profile 55 is arranged separately, a usual collecting tray can be applied and it is possible to provide a seal between the first peripheral wall part and the second peripheral wall part before the profile is arranged.
Figure 6 shows a perspective view of a fifth embodiment 60 according to the invention. Collecting tray 2, 3, 4 corresponds to the embodiment shown in figures 1 and 2. Frame 4 is height-adjustable, just as shown in figure 2, and a flange 9 is provided around collecting tray 2, 3, 4 for the purpose of attaching a tile membrane or other seal.
An elongate profile 61 is provided on upper edge 6 of frame 4 along a short and a long side of frame 4. Elongate profile 61 is provided with a first horizontal part 62 and a second horizontal part 63 attached thereto. Provided on both horizontal parts 62, 63 is a respective vertical part 64, 65. Horizontal part 62 and vertical part 64 protrude beyond frame 4 and the collecting tray 2, 3 lying thereunder so that a connection between a floor and a wall can be given a uniform finish, even though collecting tray 2, 3, 4 does not extend over the whole width of the floor.
The horizontal parts 62, 63 are further provided with bent edges 66, 67 which protrude into inflow opening 8.
Figure 7 shows a cross-section of a sixth embodiment 70 according to the invention. Drain 70 has a bottom 71 and a peripheral wall 72, the upper part of which is folded over and ends in a horizontal flange 73. A sealing membrane 74 is arranged on horizontal flange 73 so that drain 70 is sealed watertightly relative to sub-floor 75 and wall 76.
Because the width of horizontal flange 73 is greater than the thickness of wall tiles 77, an elongate profile 78 is provided which protrudes with a vertical part into inflow opening 79 of drain 70. The space between horizontal flange 73 and elongate profile 78 is filled with a foam piece 80.
Figure 8 shows a cross-section of a seventh embodiment 90 according to the invention. In this embodiment collecting tray 71, 72, 73 is the same as in the embodiment according to figure 7. A tile membrane 74 is also arranged on horizontal flange 73, after which wall tiles 77 and floor tiles 91 can be arranged in reliable manner.
An elongate profile 92 is provided in order to bridge the distance between peripheral wall 72 and wall tiles 77 as a result of the width of horizontal flange 73.
This elongate profile 92 is arranged against upright wall 72 on the outer side and, owing to the bend, profile 92 matches the visible surface of wall tiles 77. The space under profile 92 is filled with a foam 93.
It will be apparent that diverse features of the different embodiments can be interchanged and combined. The elongate profile can thus lie against both the inner side and the outer side of the peripheral wall and with the other side lie behind the wall tiles or match the visible surface of the tiles.
