DESCRIPTION

Drain with erect edge

The invention is related to the combination of a shower floor, a drain for a shower floor connected to the shower floor to discharge flowing water entering from substantially a direction on the shower floor and an adjacent floor connected to the drain and opposite the shower floor, according to the preamble of claim 1.

A combination of this type is known, for example, from EP 1577452 and DE-U-20214403.

The drainage of said combination is already known, and in the past years an elongated shower drain, sold under the brand name Easydrain, has become particularly known. This elongated drain has a collection vessel and a grill placed therein, and is usually placed on one side of a shower space, in particular under the shower space door and over the entire width thereof. The slope of the shower floor can then run in an direction to the elongated shower drain.

However, in some cases it has been found that a small part of the water and foam runs on the drain grate and thus enters the adjacent space. This is not desirable. It is also essential that the drain extends over the entire width of the slope, so that either the slope or the drain must be tailored.

Therefore, the object of the invention is to provide a combination with a drain where the drawbacks indicated above are alleviated or even obvious.

This object is achieved with a combination according to claim 1.

Water and foam flowing on the rack are slowed and stopped on the raised side so that they can still be discharged through the collection vessel.

According to an alternative of the invention, the edge of the collection vessel is high and forms the raised side. This can be done in a very simple way from a manufacturing point of view.

According to another alternative of the invention, a separate strip is provided adjacent to the drain and having a ridge protruding above the incoming flow ridge in order to form the raised side. The grid preferably comprises openings in the upper surface.

According to even another alternative of the invention, it is provided that the grid has elevation on one side to form a barrier to water and foam running on the grid. The advantage of this alternative is that existing drains can be easily modified by replacing the grid.

In an embodiment of the drain according to the invention the grid protrudes above the collection edge on at least the raised side. This creates the appearance of a completely flat drain, however an elevation is provided that forms a barrier.

In even another embodiment of the drain according to the invention the grid has a substantially U-shaped cross section with an upper surface and two descending side surfaces.

In even another embodiment of the drain according to the invention the upper surface protrudes above the incoming flow edge, and the lateral surface is provided with openings adjacent to the incoming flow edge. The approaching water will rise immediately against the side of the grid and ah will flow through the openings to the collection vessel. Due to the raised upper surface, water and possible foam cannot flow over this upper surface. The upper surface here may also be provided with openings, this further reduces the possibility of overflow.

These and other features of the invention are further clarified with reference to the attached drawings.

Figures 8A and 8B respectively show a top view and a cross-sectional view of a connection strip for a drain according to the invention.

Figure 9 shows a top view of a seventh embodiment of a drain according to the invention.

Figure 10 shows a cross-sectional view of an eighth embodiment of a drain according to the invention.

Figures 1A and 1B show perspective views of a first embodiment of a drain 1 according to the invention. The drain 1 has a collection vessel 2 with a grid 3 placed therein. On the lower side of the collection vessel 2 there is a siphon 4 that can be connected to a drain pipe by means of a connection 5. The collection vessel 2 has an inlet flow 6 and, opposite, a raised edge 7 forming the raised side of the drain 1.

Figure 2 shows the drain 1 in cross-sectional view and incorporated in a floor of, for example, a shower. The shower floor 8 is provided, for example, with tiles and slopes down towards the inlet flow 6. The water that falls on the shower floor 8 is thus carried by means of the slope created to the drain 1. The floor 9 of the adjacent space is connected to the raised side 7. The raised side 7 of the drain 1 prevents water and foam, which they run on the grid 3, they rest on the floor 9.

Figure 3 shows a second embodiment 10 of a drain. The collection vessel 11 is provided here with two erect edges 12 of equal height. In the collection vessel 11 a grid 13 is placed which has an elevation 14 on one side. This elevation 14 forms a barrier for water and foam flowing over the grid 13.

Figures 4A and 4B show a third embodiment 20 of a drain according to the invention. The drain 20 here also has a collection vessel 21 with side edges 22 of equal height. The shower floor 23 is flush with the inlet stream 22 of the drain 20. On the opposite side there is a strip 24 that can be adjusted to the height of the adjacent floor 25. In Figure 4A, the adjacent floor 25 it is at the same level as the grid 26, and the strip 24 provides a barrier. In the variant according to Figure 4B, where the adjacent floor 25 is slightly raised with respect to the grid 26, the strip 24 also provides the necessary barrier.

Figure 5 shows a cross-sectional view of a fourth embodiment 30 of the drain according to the invention. This drain 30 has a collection vessel 31 with an edge 32 of incoming flow and an elevated edge 33 that is taller than the edge 32 of incoming flow. This raised edge 33 provides the barrier. The drain 30 is also provided with a grid 34, whose upper surface extends from the inlet stream 32 to the raised edge 33. The drain 30 therefore has an appearance similar to that of a conventional drain. However, due to the upper rising surface of the grid 34, the flow of water and foam on the grid 34 is prevented, and thus a barrier is created for this purpose in combination with the raised edge 33.

Figure 6 shows a cross-sectional view of a fifth embodiment 40 of a drain according to the invention. The collection cup 41 is also provided here with two edges 42 of equal height. These two edges 42 are connected to the shower floor 43 and the adjacent floor 44. In the collection vessel 41 a grid 45 is placed, the upper surface of which is higher than the edges 42. The lateral surface 46 adjacent to the shower floor 43 , and thus to the inlet stream 42, is provided with openings 47. This drain 40 thus has the appearance of a threshold and also prevents water and foam from flowing over the upper surface 45 to the adjacent ground 44. This is prevented because water and foam flowing over the shower floor 43 rises against the side surface 46 and ah enters the collection vessel 41 directly through the openings 47.

Figure 7 shows a sixth embodiment 50 of a drain according to the invention. The collection vessel here again has two side edges of equal height and the grid 52 is provided with an elevated side 53 that forms the desired barrier. In this embodiment, the grid 52 protrudes over the edges of the collection cup 51.

Figure 8A shows a top view of a shower floor 60 with a drain 61 according to the invention therein. This drain, for example, may be one of the previous embodiments.

When the drain 61 does not extend fully between the two walls 62, there is still a danger that water and foam flow from the shower floor 60 to the adjacent floor 63. In order to prevent this, a strip 64 is provided, which forms a barrier for the other parts, adjacent to the shower drain 61, which is provided with a raised side according to the invention. Figure 8B shows a cross section of this strip 64. The strip 64 can be made with a length so that a standard size drain can still discharge water from the entire slope.

Figure 9 shows a seventh embodiment 70 of a drain according to the invention. This drain 70 is curved and for example suitable for corner shower curtains with semicircular shower doors. Barrier strips 71 corresponding to strips 64 shown in Figures 8A and 8B are disposed adjacent to the semicircular drain 70.

Figure 10 shows an eighth embodiment 80 of a drain according to the invention. This drain 80 has a collection vessel 81 with an inlet flow 82 and an elevated edge 83. The incoming flow edge 82 is connected to the shower floor 84 and the raised edge 83 is connected to the adjacent floor 85. Like the edge elevated 83 form a

barrier, it is possible to reduce the distance between the inlet stream 82 and the raised edge 83. Then in this space a narrower grid 86 is placed. However, in order to ensure a good through flow of the incoming water, the vessel Collection 81 must have a tank 87 in which the collected water can accumulate and subsequently be discharged through an outlet. The advantage of this embodiment is that with this you get a very narrow drain that is practically hidden from view.
