Abstract
Abstract A toilet lid closing device for use on toilets of the type having a vertical tank with a flushing lever, a bowl, a seat and an overlying lid pivotally mounted by a hinge pin, has a torsional coil spring received around the hinge pin which biases the lid and the seat to a closed position. A channel shaped bracket has a horizontal mounting surface secured by the toilet seat mounting bolts, with perpendicularly attached parallel support legs for mounting end portions of a pair of dampening cylinders. An adjustment bracket allows independent adjustable positioning of the dampening cylinders. Each of the dampening cylinders has an extensible rod provided with a circumferential groove for engagement with a spring biased locking pin which retains the rod in a extended position. End portions of the extensible rods have journal bearing ends received on mounting pad axles secured to the underside of the lid and the seat. A sheathed cable is operatively connected to each of the locking pins for disengaging the pins from the grooves upon actuation of the flushing lever. A cable actuation bracket is secured on a side wall of the toilet tank and includes a slider mounted for linear reciprocal movement.
