Abstract

Drainage device for arrangement on a floor tile, the drainage device, when at least partially assembled in the floor, has at least two pipe lengths moveable relative to one another in such a way that a movement of the pipe lengths relative to one another allows an aperture in the floor tile and the upper inlet aperture of the drainage device to be made to coincide at least partially with one another. At the same time the pipe lengths have flanges extending radially outwards, which are sealed against one another by seals.

Claims

1. A drainage device for arrangement on a floor tile having an aperture for drain water, comprising

an upper inlet aperture, into which drain water, having passed through the aperture in the floor tile, can enter,

parts preassembled in the floor area, which can be connected to a drainage pipe, so that drain water, having passed through the inlet aperture, can pass into the drainage pipe,

two parts, which when assembled at least partially in the floor area are moveable relative to one another, in such a way that their movement relative to one another allows the aperture in the floor tile to be moved in relation to the parts preassembled in the floor area.

2. The drainage device as claimed in claim 1, wherein the aperture in the floor tile and the upper inlet aperture of the drainage device can be made to coincide at least partially with one another through a movement of the parts relative to one another.

3. The drainage device as claimed in claim 1, wherein the parts of the drainage device moveable relative to one another take the form of pipe lengths or tubular sections arranged at least partially one inside the other, which in particular enclose a deformable annular space or partially annular space between them.

4. The drainage device as claimed in claim 3, wherein the inner pipe length or the inner tubular section has an upper flange extending radially outwards, which is supported so that it is horizontally moveable.

5. The drainage device as claimed in claim 3, wherein the outer pipe length or the outer tubular section has an upper flange extending radially outwards.

6. The drainage device as claimed in claim 1, wherein the flange of the inner pipe length or the inner tubular section is arranged, at least in sections, parallel to and at a distance from the flange of the outer pipe length or the outer tubular section.

7. The drainage device as claimed in claim 5, wherein the drainage device comprises at least one seal which seals the flange of the inner pipe length or the inner tubular section against the flange of the outer pipe length or the outer tubular section.

8. The drainage device as claimed in claim 7, wherein at least one seal takes the form of an O-ring.

9. The drainage device as claimed in claim 7, wherein at least one seal takes the form of a corrugated bellows seal.

10. The drainage device as claimed in claim 5, wherein the flange of the outer pipe length or the outer tubular section is bent upwards at its radially outer end, so that the bend thereby produced peripherally encloses the flange of the inner pipe length or the inner tubular section, at least in sections.

11. The drainage device as claimed in claim 10, wherein at least one seal is arranged between the outer edge of the flange of the inner pipe length or the inner tubular section and the bend peripherally enclosing this flange.

12. The drainage device as claimed in claim 5, wherein the flange of the outer pipe length or the outer tubular section is bent upwards and radially inwards at its radially outer end, so that the bend thereby produced is arranged at least partially above the flange of the inner pipe length or the inner tubular section.

13. The drainage device as claimed in claim 12, wherein at least one seal is arranged between the bend, which extends at least partially above the flange of the flange of the inner pipe length or the inner tubular section, and the upper side of the flange of the flange of the inner pipe length or the inner tubular section.

14. The drainage device as claimed in claim 7, wherein the drainage device comprises two seals, which are arranged on the upper side and the underside of the flange of the inner pipe length or the inner tubular section.

15. The drainage device as claimed in claim 14, wherein one of the two seals rests on the upper side of the flange of the outer pipe length or the outer tubular section and the other of the two seals bears on the underside of the bend, which extends at least partially above the flange of the inner pipe length or the inner tubular section.

16. The drainage device as claimed in claim 3, wherein the outer pipe length or the outer tubular section is part of a drain well.

17. The drainage device as claimed in claim 1, wherein the parts moveable relative to one another comprise a drain well, which is moveable in relation to parts preassembled in the floor area.

18. The drainage device as claimed in claim 17, wherein the parts preassembled in the floor area comprise seating devices which are capable of at least partially receiving the drain well, the drain well being moveable in relation to the seating devices.

19. The drainage device as claimed in claim 18, wherein the seating devices and the drain well each comprise a union connection, the union connection of the drain well having been at least partially received by the union connection of the seating devices.

20. The drainage device as claimed in claim 19, wherein sealing devices, in particular a sealing ring or a lip packing, which allow a movement of the union connections relative to one another, are arranged between the two union connections.

23. An arrangement of a drainage device on a floor tile, comprising a floor tile having an aperture, through which drain water can pass, characterized by a drainage device as claimed in claim 1.

21. A drainage device for arrangement on a floor tile having an aperture for drain water, comprising

an upper inlet aperture, into which drain water, having passed through the aperture in the floor tile, can enter,

parts preassembled in the floor area, which can be connected to a drainage pipe, so that drain water, having passed through the inlet aperture, can pass into the drainage pipe,

two pipe lengths or tubular sections arranged at least partially one inside the other, which when assembled at least partially in the floor area are moveable relative to one another, in such a way that the aperture in the floor tile can be moved in relation to the parts preassembled in the floor area through a movement of the pipe lengths or tubular sections relative to one another,

the inner pipe length or the inner tubular section having an upper flange extending radially outwards.

22. A drainage device for arrangement on a floor tile having an aperture for drain water, comprising

an upper inlet aperture, into which drain water, having passed through the aperture in the floor tile, can enter,

seating devices preassembled in the floor area, which can be connected to a drainage pipe, so that drain water, having passed through the inlet aperture, can pass into the drainage pipe,

a drain well which can be at least partially received by the seating devices, and which is moveable in relation to the seating devices in such a way that the aperture in the floor tile can be moved in relation to the seating devices,

the seating devices and the drain well each comprising a union connection, the union connection of the drain well being at least partially received by the union connection of the seating devices.

24. The arrangement as claimed in claim, wherein the floor tile takes the form of natural stone, a molding or ceramic tile or the like.
