Description

DESCRIPTION

Drain comprising a tubular casing and a siphon

The invention relates to a drainage and surrounding soil according to the preamble of claim 1. A drainage and surrounding soil as such is known from DE 202006014745.

WO 2009/091245 describes an elongated shower drain. This shower-type drain has a channel-shaped tray in which a grid with a U-shaped cross-section is placed. According to this publication, an adjusting frame is further placed in the lower tray in order to bring the grid to the same height as the surrounding tile floor in a simple way.

The trend in the field of drains is that drainage should be as less visible as possible. To this end, the width of the grid is reduced. The disadvantage of this is that as the width of the rack is reduced, the width of the lower tray is also simultaneously reduced. The storage volume of the lower tray, therefore, decreases, whereby the amount of water to be drained per unit of time decreases. The result can be that a layer of water remains on the ground, which can spill onto the ground surface in an unwanted direction.

Another known elongated drain has, in the position of the usual grid, a tray-shaped support in which, for example, a tile can be placed. The water can then flow into the lower tray through an opening between this tile and the surrounding floor. In this tile drain, an opening is normally formed on both sides of the tiled tray support. Furthermore, the tile pattern of the surrounding floor is interrupted by the tile on the backing, whereby a tile drain known as such is even visible as well. The construction, in particular, of the tile support, is furthermore unfavorable from the point of view of manufacture.

GB 2210392 shows a drain, in which the drain consists of a lower part and an upper part. The upper part has a threaded part into which a part can be screwed with a grid. The grid can therefore be adjusted in height. In addition, the upper part is slidable in the lower part, so the grid can also be adjusted in the horizontal plane.

The drawback of the embodiment shown is, however, that at least both the lower and upper parts are laid on the floor before a final layer, such as tiles, can be laid out. This is because without laying the upper part of the drain it is not possible to obtain a flat substrate in order to provide a final layer, such as a tile layer.

Now, it is an object of the invention to provide a drain, in which the above-mentioned drawbacks are mitigated, or even eliminated.

This objective is achieved with a drainage and a surrounding soil according to claim 1.

In a drainage and surrounding soil according to the invention, the tubular casing is integrated into the soil. The top layer of the surrounding floor such as, for example, a tile floor, is laid over the tubular shell up to the elongated opening. By this, only an elongated opening is visible. This elongated opening can be a narrow opening, since sufficient drainage capacity is present in the tubular housing directly below the elongated opening.

By using a tubular casing a flat upper surface is obtained, thanks to which the tile layer can be easily laid.

The drain used in the invention comprises a vertical edge arranged along the periphery of the elongated opening in the lower surface. The tile floor here is positioned against the vertical edge arranged along the periphery of the elongated opening in the lower surface. The vertical edge allows for a delimitation and a flawless finish. The vertical edge also ensures a good seal because moisture can no longer pass under the tiles.

It is possible with the tubular casing to make a very flat drain. The tubular casing can be arranged here in only a part of the covering floor, whereby it is not necessary to damage the underlying floor system, for example by drilling a hole in the floor system. A typical height of the tubular shell could be 1 to 2 centimeters.

The tubular housing can be arranged directly underneath, for example, a tiled floor, since the floor load is low in sanitary applications.

In one embodiment of the drain used in the invention, at least a portion of the vertical peripheral edge may be provided on the upper side with a horizontally outwardly bent part and an inwardly bent part connecting there, so that the upper side is provided with a horizontal projection of U-shaped cross-section.

A sealing membrane, which ensures a watertight transition between the drain and the surrounding soil, can easily be added to the horizontal projection.

In a preferred embodiment of the drainage used in the invention, the upper surface is here the separate sheet part protruding with the peripheral edges at the horizontal shoulder of the U-shaped cross section. The separated sheet part is preferably arranged so as slider on the horizontal shoulder.

Because the separate sheet portion is slidably arranged on the horizontal shoulder, the position of the vertical edge around the elongated opening can easily be adapted to the surrounding ground. Therefore, it is possible to correct a skewed positioning of the tubular housing by rotating the upper surface with respect to the shoulder. It is also possible, by means of a regulation, to have the flow inlet opening directly connected to an entire floor tile.

In the drain used in the invention, the upper edge of the peripheral wall comprises an inwardly directed horizontal shoulder, which horizontal shoulder forms, together with a separate sheet portion, the upper wall of the housing. Spacers are preferably arranged on the underside of the separated sheet part in order to support the separated sheet part at a distance from the bottom surface and against the horizontal shoulder.

This embodiment provides a drain in which the flow inlet opening is slidable while the tubular housing remains compact.

In a highly preferred embodiment of the drain used in the invention, a closable inspection opening is provided on the upper surface, above the discharge opening. This inspection opening preferably lies flush with the upper side of the vertical edge. The inspection opening can here be covered with an aesthetically designed cover.

The width of the elongated opening in the upper surface is preferably less than 50%, and even more preferably less than 25%, of the width of the tubular shell.

In still another embodiment of the drain used in the invention, the separate sheet portion is slidably disposed in the elongated opening. The width of the elongated flow inlet opening can be regulated using this separate sheet portion.

In still another embodiment of the drain used in the invention, the top surface is stepped, such that the wall tiles can, for example, be laid on top. Such a drain is thus particularly suitable for arrangement against a wall.

These and other features of the invention are further explained with reference to the accompanying drawings.

The upper wall 25 of the drain 20 is a separate part projecting towards the horizontal U-shaped shoulder 23, 24. Therefore, it is possible to slide the upper wall alternatively.

An elongated flow inlet opening 26 is arranged in the upper wall 25. An upward edge 27 is arranged along this flow inlet 26. Because the upper wall 25 can slide alternately, it can be adjusted accordingly. mode the distance between the vertical edge 27 and the surrounding tile floor that may be placed on the top wall 25.

A sealing membrane 28 can furthermore be arranged on the horizontal projection 23, 24. The edge of the sealing membrane 28 is provided with a double edge, within which the horizontal projection can be received in order to make, of this way, a good seal.

Figure 4 shows a third embodiment of a drain 40. This drain 40 is also preferably manufactured from laminated material. The drain 40 here consists of two parts, in which the lower part comprises a lower wall 41, a peripheral wall 42 and an inwardly directed horizontal shoulder 43 arranged on the upper side of the peripheral wall 42.

The upper part of the drain 40 consists of a wall part 44 supported at a certain distance from the lower wall 41 by spacers 45. An elongated flow inlet opening 46 is further arranged in the wall part 44. Furthermore, it also A vertical edge 47 is disposed around this elongated flow inlet opening 46.

Because the wall portion 44 is narrower than the width of the bottom portion 41, 42, 43, the wall portion 44 can alternatively slide such that the flow inlet opening 46 can be adjusted to a floor, such as a tile floor, disposed over drain 40.

The wall tiles can be placed on the shoulder 43. A vertical edge 47 extends here against the wall tiles. So here the drain can be sealed with respect to the wall tiles. Should moisture nevertheless enter between the wall tiles and the upward edge 47, this moisture will nonetheless pass to the bottom of the drain 40. The wall portion 44 may optionally also be provided with a perforation for better drainage of a liquid that leaks as such.

The perforations described above can also be applied in the other embodiments.

Figure 5 shows a fourth embodiment of a drain 50 according to the invention. The cross section shown passes over the outlet tube 51. The drain 50 has a lower surface 52 with a peripheral wall 53. The upper surface 54, 55, 56 is a combination of the embodiments shown above. On one side an inwardly bent shoulder 53 is formed which acts in cooperation with the upper surface 54, while on the other side an inward bent shoulder is provided which acts in cooperation with a U-shaped bent shoulder 56.

The upper surface 54, 55, 56 further has a flow inlet opening 57 which is bordered by the vertical edge 58.

Furthermore, disposed on a lower surface 52 is a discharge opening 59 to which a siphon constructed from a sloping wall 60 and a vertical wall 61 is connected. These two walls 60, 61 provide the necessary trap for malodors.
