ABSTRACT:
The seat lifter is for lifting a toilet seat. The seat lifter includes a foot pedal, cables, pulleys, a base, spring hinge, lifting arm, cable blocks, and a counter weight. The hinge holds the base down on to the toilet with its mounting hardware. The whole mechanism is held to the toilet by the toilet seat mounting holes in the toilet bowl. The seat is always in the down position until the foot pedal is depressed. Once the foot pedal is depressed a cable is pulled against the cable block then a small diameter pulley is rotated on a shaft that is pinned to a larger diameter pulley (this pulley assembly is called a reduction spool because it takes a small movement of the foot pedal to make a large enough movement to raise the seat to the proper height). The larger pulley then pulls a longer cable, that pulls a cable block mounted to a lifting arm with a counter weight, which pulls the arm down, that in turn moves a spring hinge attached to the seat. The seat is now in the lifted position. To return the seat to the down position simply release the pedal.
