Abstract

Abstract A drain and overflow device for bathtubs having overflows at different heights and various slopes. By rotation of a turning knob (6) adjacent the overflow housing (15), the body (8) of the drain valve (1) can be raised and lowered by means of a Bowden draw tube (10). A bellows (5) is inserted in the overflow conduit (11), and this enables adjustment of the length of the latter and orientation of the overflow housing (15) to the dimensions of the bathtub. In order to prevent twisting of the Bowden cable (12) during actuation of the turning knob (6), the cable is rotatably arranged on a cable bolt (28). For this purpose, an easily rotatable bearing (34) is inserted in an axial bore (33) of the cable bolt (28), and on this bearing rests a disc (36) to which the Bowden cable is attached.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 154 words
Drain and overflow device for bathtubs having a drain valve (1) and a turn knob (6) adjacent to an overflow (4), a body (8) of said drain valve being lifted into open position by rotation of said turn knob by means of a Bowden draw tube (10), wherein (a) a conduit (11) for said overflow is formed at least partly as a bellows (5) so as to enable adaptation of the length and orientation of said overflow to bathtubs of diverse dimensions; (b) a flexible Bowden cable (12) being entirely contained within said Bowden draw tube (10) and being operably rotatably connected to a rigid, axially slidable cable bolt (28) having an axial bore (33) containing a bearing (34) to which said Bowden cable (12) is attached, said bearing (34) being rotatable relative to said cable bolt (28), whereby twisting of said Bowden cable (12) upon rotation of said cable bolt (28) is obviated.
Claim 2
Dependent Claim 154 words
Drain and overflow device for bathtubs having a drain valve (1) and a turn knob (6) adjacent to an overflow (4), a body (8) of said drain valve being lifted into open position by rotation of said turn knob by means of a Bowden draw tube (10), wherein (a) a conduit (11) for said overflow is formed at least partly as a bellows (5) so as to enable adaptation of the length and orientation of said overflow to bathtubs of diverse dimensions; (b) a flexible Bowden cable (12) being entirely contained within said Bowden draw tube (10) and being operably rotatably connected to a rigid, axially slidable cable bolt (28) having an axial bore (33) containing a bearing (34) to which said Bowden cable (12) is attached, said bearing (34) being rotatable relative to said cable bolt (28), whereby twisting of said Bowden cable (12) upon rotation of said cable bolt (28) is obviated.
Claim 3
Dependent Claim 21 words
Device according to claim 1, wherein said bellows (5) is inserted between an overflow housing (15) and an overflow pipe (14).
Claim 4
Dependent Claim 34 words
Device according to claim 1, comprising a disc (36) with a central recess (37) on the inner transverse plane (35) of said bearing (34), said Bowden cable (12) being rotatably attached to said disc.
