A floor drain (100) comprising a bottom part (4) having at least one discharge opening (5), a front part being integral with the bottom part (4) and having a first part (3b) being inclined to said bottom part at an angle being at least 30°, such as at least 45°, preferably at least 60° more preferably at least 75° and even more preferably about 90° or at least 90° and having a flange part (3a) being horizontal or inclined to horizontal at an angle being less than 20° such as less than 17°, preferably less than 15°, such as less than 10°, more preferably less than 5°, tow side walls (2) integral with said bottom part and said first part, and a back part (1) being integral with said bottom part (4), said back part (1) extending vertically from the bottom part (4), through and above the plane defined by the flange part (3a).
A floor drain (100) for use adjacent to a wall in a wet area in a building structure, such as in a bath room or bath cabin, said floor being exposed to running water in use of said wet area, the wall and the floor including a watertight covering (8, 9, 17, 18), said floor preferably being inclined towards said wall to enable said water to flow by gravity towards said wall and to be discharged through said floor drain arranged adjacent said wall, said floor drain (100) comprising:
A floor drain (100) according to the preceding claim, at least one of the side walls (2) further comprising an intermediate part being horizontal or inclined to horizontal at an angle less than 15°, said at least one intermediate part being arranged at the same horizontal level as the flange part of the front part, or slightly above.
A floor drain (100) according to any of the preceding claims, said drain being elongated, each of said side walls (2) extending through and above a plane defined by the flange part (3a), said side walls (2) being adapted to be at least partially covered by a part of said water tight covering (8, 17) of said wall (16), and said bottom part (4) defining a sloping surface to enable said water to flow by gravity along said sloping surface towards said at least one discharge opening (5).
A floor drain (100) according to any of the preceding claims, said front and back (1) parts and said side walls (2) comprising bearing surfaces (15) for supporting said grating (12).
A floor drain (100) according to any of the preceding claims, said back part (1) including mounting means (200) for securing said floor drain (100) to an essentially vertical or horizontal surface.
A floor drain (100) according the preceding claim, said mounting means being receiving holes for screws or nails.
A floor drain (100) according to any of the preceding claims, further comprising a heightening frame (26) for supporting said grating (12).
A floor drain (100) according to any of the preceding claims, said floor drain (100) including a vertical surface (13) providing a lateral support for a floor covering (9).
A floor drain (100) according to any of the preceding claims, said flange part (3a) having at an extremity thereof remote from said first part (3b) a rearwardly bent section.
A floor drain according to any of the previous claims, said floor drain (100) moreover including a trap connected to said discharge opening (5) and having an outlet (6) connectable to discharge tubing.
A floor drain (100) according to the preceding claim, said trap including a funnel shaped part (50) with a straight part and a bowl shaped part (51) with a straight part, said straight parts being arranged concentrically such that at least a part of the straight part of the funnel shaped part extends inside at least a part of the straight part of the bowl shaped part (51), said straight part and said bowl shaped part (51) being arranged within a further trap bowl (6′) including said outlet (6).
A floor drain (100) according to the preceding claim, wherein the bottom of the bowl shaped part (51) is torus member shaped.
