ABSTRACT:
A toilet seat elevator system comprising a base, a horizontal pedal member hinged to the base, and a vertical arm hinged between the end of the pedal member and the seat. Variable-length lever arms adjust the static leverage exerted through the linkage. A non-linear spring in the linkage adjusts the dynamic leverage for smoother operation. The toilet seat elevator system may be foot operated or through a sound recognition device.
