A foot operated double acting lever for rotating a lid hinged to a base from a first position to a second position such as lifting the seat of a toilet bowl without touching the seat with the hands wherein the lid (or seat) is locked in the second position when the pedal is not depressed thereby maintaining the seat in its second position and is unlocked by depressing the pedal a second time and allowing the lid to rotate back to its first position at a speed that is under control of the foot on the pedal. The device includes a rotating housing coupled to one end of the lever (opposite the end with the pedal) that is coupled to a drive gear that turns a hinge gear mounted to rotate on the same axis as the lid. In order that the lid be locked in the second position, a lock catch engages the drive gear and a fixed slot thereby locking the drive gear. When the pedal is depressed, the lock catch is withdrawn permitting the drive gear to rotate thereby allowing the lid to rotate on its hinge back to its first position.
