Abstract
Abstract A foot and leg exerciser comprises an inclinable base, at least one foot pad for supporting and moving the foot of the user, and means for moving the foot pads in a pattern to provide mild exercise which simulates normal walking. The heel ends of the foot pads are moved in a vertical plane by revolving cranks driven by an electric motor through reduction gears, while the toe ends of the foot pads are supported on adjustable rocker arms. Starting, stopping and speed of the motor are controllable by the user through a remote control box. A number of features of the design are directed to safety in the operation of the exerciser.
