Abstract: It is desirable to be able to lift, lower and lock a toilet seat assembly in position without any hands-on interaction with the toilet seat assembly. In order to accomplish this objective the invention incorporates a selection of devices having additional mechanical advantage when pivoting the seat assembly. In one preferred embodiment of the invention, a cable-operated foot lever is used in combination with a crank portion on the hinge of the toilet seat. In another preferred embodiment of the invention, a system of planetary gears is used in the lever and/or the hinge assembly.
