ABSTRACT:
A toilet seat lifting device for selectively raising and lowering the seat of a toilet includes a base disposed on a floor surface, a stanchion secured to the front of the base, and a foot pedal pivotably mounted to the stanchion. A plurality of link arms are pivotably mounted to the stanchion and are linked to the foot pedal so that movement of the foot pedal pivots the link arms. Mounted to the distal ends of the link arms is a lifting arm retaining member which carries an elongated lifting arm capable of vertical repositioning on the lifting arm retaining member to accommodate variously-sized toilet bowls and seats. The upper end of the lifting arm is attached to the under-side of the toilet seat. A main spring attached to the link arms assists in raising and dampens the lowering of the toilet seat, and a helper spring projecting upwardly from the base between the link arms engages when the toilet seat goes past the top dead center position in order to assist in returning the toilet seat to the lowered state.
