SANITAERER APPARAT MIT UEBERSTROEMWEG

摘要

The manufacture of a drain fitting for sinks, washbasins, bathtubs or such sanitary equipment with a drain insert (12) secured in a drain hole (11) in which a plunger (16) consisting of a guide and a plunger head as the plug for the drain hole (11) can be moved longitudinally via a plunger rod (18), whereby the upper edge region of the drain insert (12) forms a sealing collar (19) for the plunger head (15) in its closed position and the upper edge region (14) of the drain insert (12) forming a seat is inserted deeply into the wall of the drain hole (11) of the sanitary equipment, is to be simplified. To this end, a fixed disc (25) with a smaller diameter can be inserted into the drain hole (11) and the drain insert of a standard drain fitting with a larger diameter than the plunger head (15) is inserted in the wall of the drain hole (11) at such a distance from the disc (15) that the plunger head (15) is movable between its closed and open positions beneath the fixed disc (25).
