ABSTRACT:
A toilet seat is equipped with an hydraulic closing mechanism to provide automatic lowering of the toilet seat upon operation of the flush mechanism. A uni-directional hydraulic motor is coupled in driving relation with a very high ratio reduction gear, to drive an output shaft at slow speed. The seat of the toilet, and possibly also the toilet lid are rotatably mounted upon the output shaft, being coupled thereto by way of adjustable friction clamps, so that the seat and lid may not slip, relative to the shaft, under their own weight, while yet permitting ready manual pivotal repositioning of the lid, or lid and seat, regardless of movement of the shaft. The clamps also permit the output shaft to complete its rotation even when the seat is fully lowered. The hydraulic motor is driven by ancillary water re-routed from the toilet tank, which flows only as the tank is refilling after flushing. The ancillary water is routed back to the toilet tank, to perform its normal wash and fill functions, after driving the seat to its lowered position.
