Abstract: A device for lowering a toilet seat when the toilet is flushed comprises a trip wire attached at one of its ends to the toilet flush crank arm outside the toilet tank and leading through guide means to a point near the edge of the toilet seat. The trip wire is guided by guide means along the front of the tank from the crank arm to a point near the toilet seat in its upright position where the guide means turns the other end of the wire from its path along the front of the tank towards the toilet seat. When the crank arm is pushed down to flush the toilet, the wire is pushed through the guide means and the other end of the wire pushes the toilet seat forward to an unstable position from which the seat drops to its seating position on the toilet bowl.
