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.
