Abstract

The invention relates to a floor drain (1) comprising an elongate housing (2), said housing having a base wall (3), two side walls (4, 5) extending in a longitudinal direction, two end walls (6, 7) connecting the side walls (4, 5) to one another, and a ceiling wall (8) provided with an elongate inlet opening (10) extending in the longitudinal direction (L), and further comprising an outflow connection piece (11) extending outwardly from the base wall (3) or one of the side walls (4, 5) or one of the end walls (6, 7) for the connection of a drain tube, wherein the inlet opening (10) ends in each case at a distance to the front-side ends of the ceiling wall (8) and at a distance to at least one of the side walls (4, 5), so that a receiving flange surrounding the inlet opening (10) is formed, on which a sealing gasket (14) is or can be attached.

First claim

The invention claimed is:

1. A floor drain ( 1 ) comprising:
an elongate housing ( 2 ) having a base wall ( 3 ), two side walls ( 4 , 5 ) extending in a longitudinal direction, two end walls ( 6 , 7 ) connecting the side walls ( 4 , 5 ) to one another, and a ceiling wall ( 8 ) provided with an elongate inlet opening ( 10 ) extending in the longitudinal direction (L), and an outflow connection piece ( 11 ) extending outwardly from the base wall ( 3 ) or from one of the side walls ( 4 , 5 ) or from one of the end walls ( 6 , 7 ) for the connection of a drain tube, wherein the inlet opening ( 10 ) terminates in each case a distance away from the front-side ends of the ceiling wall ( 8 ) and a distance away from at least one of the side walls ( 4 , 5 ) so that a receiving flange surrounding the inlet opening ( 10 ) is formed, the receiving flange being attachable to a sealing gasket 14 );
wherein the ceiling wall ( 8 ) defines at least one incline falling away in the direction of the inlet opening ( 10 ), or that the base wall ( 3 ) defines an incline falling away towards the outflow connection piece ( 11 ).

2. The floor drain ( 1 ) according to claim 1 , wherein the inlet opening ( 10 ) is positioned a distance (b) away from the front-side ends of the ceiling wall ( 8 ), which distance is at least 10 mm and/or that the inlet opening ( 10 ) has a width (B) in the range of from 4 to 12 mm.

3. The floor drain ( 1 ) according to claim 1 , wherein the sealing gasket ( 14 ) is attached to the ceiling wall ( 8 ) and the sealing gasket ( 14 ) projects over the front-side and/or side ends of the ceiling wall ( 8 ).

4. The floor drain ( 1 ) according to claim 1 , wherein the base wall ( 3 ) and a lower region of the inner wall of the outflow connection piece ( 11 ) merge into one another.

5. The floor drain ( 1 ) according to claim 1 , further comprising at least one supporting strut ( 13 ) extending in the longitudinal direction between a side wall ( 5 ) and the ceiling wall ( 8 ) or between the base wall ( 3 ) and the ceiling wall ( 8 ).

6. The floor drain ( 1 ) according to claim 1 , wherein the housing ( 2 ) includes feet ( 9 ) extending to the side walls ( 4 , 5 ) or the front walls ( 6 , 7 ).

7. The floor drain ( 1 ) according to claim 1 , wherein the inlet opening ( 10 ) borders directly on one of the side walls ( 4 ).

8. The floor drain ( 1 ) according to claim 1 , wherein the sealing gasket ( 14 ) projects upwards from the side wall ( 4 ) and is attached to one of the side walls ( 4 ).

9. The floor drain ( 1 ) according to claim 8 , wherein the housing ( 2 ) has at least one upwardly extending bar ( 30 ) positioned adjacent to the inside of the side wall ( 4 ) on which the inlet opening ( 10 ) directly borders and extends from the base wall ( 3 ) or the side wall ( 4 ), the side wall ( 4 ) and the at least one bar ( 30 ) defining between them a receiving slot ( 31 ), and an elongate, strip-shaped screen ( 32 ) being insertable into the receiving slot ( 31 ) and the protrusion of which over the ceiling wall ( 8 ) is varied by the corresponding choice of insertion depth, the at least one bar ( 30 ) extending at least over the entire length of the inlet opening ( 10 ).

10. The floor drain ( 1 ) according to claim 1 , wherein the housing ( 2 ) is made in one part or is made up of individual components connected to one another undetachably.

11. The floor drain ( 1 ) according to claim 1 , further comprising an odour trap formed within the housing ( 2 ) which fluidically connects the inlet opening ( 10 ) to the outflow connection piece ( 11 ), the odour trap having at least two accumulation chambers ( 22 , 23 ) which, in the correct state of the floor drain ( 11 ), fill with accumulated water, and an outflow chamber ( 24 ), the first accumulation chamber ( 22 ) and the second accumulation chamber ( 23 ) being separated from one another by a first partition wall ( 25 ) extending in the longitudinal direction (L) and downwards from the ceiling wall ( 8 ), said first partition wall being provided in the lower region with one or with a number of first through holes ( 26 ), and the second accumulation chamber ( 23 ) and the outflow chamber ( 24 ) being separated from one another by a second partition wall ( 27 ) extending in the longitudinal direction (L) and upwards from the base wall ( 3 ), said second partition wall being provided in the upper region with one or with a number of second through holes ( 28 ), and/or the accumulation chambers ( 22 , 23 ) being closed on at least one of their front sides by an additional partition wall ( 29 ).

12. The floor drain according to claim 11 , wherein the inlet opening ( 10 ) is positioned centrally and equidistantly from the side walls ( 4 , 5 ), and wherein the odour trap has a first accumulation chamber ( 22 ) positioned centrally and two second accumulation chambers ( 23 ) each positioned adjacent to the first accumulation chamber ( 22 ) and connected fluidically to a common outflow chamber ( 24 ), or that the height of the first and the second through holes ( 26 , 28 ) is between 4 and 12 mm, or that the odour trap and the housing ( 2 ) are made in one part or are connected undetachably to one another.

13. The floor drain ( 1 ) according to claim 7 , wherein the housing ( 2 ) has at least one upwardly extending bar ( 30 ) positioned adjacent to the inside of the side wall ( 4 ) on which the inlet opening ( 10 ) directly borders and extends from the base wall ( 3 ) or the side wall ( 4 ), the side wall ( 4 ) and the at least one bar ( 30 ) defining between them a receiving slot ( 31 ), and an elongate, strip-shaped screen ( 32 ) insertable into the receiving slot ( 31 ) and the protrusion of which over the ceiling wall ( 8 ) is varied by the corresponding choice of insertion depth, the at least one bar ( 30 ) extending at least over the entire length of the inlet opening ( 10 ).

14. A floor drain ( 1 ) comprising:
an elongate housing ( 2 ) having a base wall ( 3 ), two side walls ( 4 , 5 ) extending in a longitudinal direction, two end walls ( 6 , 7 ) connecting the side walls ( 4 , 5 ) to one another, and a ceiling wall ( 8 ) provided with an elongate inlet opening ( 10 ) extending in the longitudinal direction (L), and an outflow connection piece ( 11 ) extending outwardly from the base wall ( 3 ) or from one of the side walls ( 4 , 5 ) or from one of the end walls ( 6 , 7 ) for the connection of a drain tube, wherein the inlet opening ( 10 ) terminates in each case a distance away from the front-side ends of the ceiling wall ( 8 ) and a distance away from at least one of the side walls ( 4 , 5 ) so that a receiving flange surrounding the inlet opening ( 10 ) is formed, the receiving flange being attachable to a sealing gasket 14 );
wherein the base wall ( 3 ) and a lower region of the inner wall of the outflow connection piece ( 11 ) merge into one another.

15. A floor drain ( 1 ) comprising:
an elongate housing ( 2 ) having a base wall ( 3 ), two side walls ( 4 , 5 ) extending in a longitudinal direction, two end walls ( 6 , 7 ) connecting the side walls ( 4 , 5 ) to one another, and a ceiling wall ( 8 ) provided with an elongate inlet opening ( 10 ) extending in the longitudinal direction (L), and an outflow connection piece ( 11 ) extending outwardly from the base wall ( 3 ) or from one of the side walls ( 4 , 5 ) or from one of the end walls ( 6 , 7 ) for the connection of a drain tube, wherein the inlet opening ( 10 ) terminates in each case a distance away from the front-side ends of the ceiling wall ( 8 ) and a distance away from at least one of the side walls ( 4 , 5 )
