摘要：A toilet seat lifting and lowering device for pivoting the seat to its raisedposition and for pivoting it back to its horizontal position without having to touch theseat. A first lever arm is rigidly attached at one end to a first part of a torque transfermechanism and at its other end to a foot pedal and a second lever arm is rigidly attached
at one end to a second part of the torque transfer mechanism and at its other end to thetoilet seat. With the toilet seat in its horizontal position, a downward force on the pedalproduces a rotation of the first part of the torque transfer mechanism which produces anopposite rotation of the second part of the torque transfer mechanism causing the toiletseat to pivot to its raised position. Lifting the pedal, preferably by providing an upwardforce under the pedal, lowers the seat to the horizontal position. In a preferred
embodiment, a counterweight positionable on the first lever arm is provided to provide aconstant torque to partially oppose the torque produced by the weight of the toilet seatabout its pivot axis. In a preferred embodiment, the first and second parts of the torquetransfer mechanism are both cams.
