Abstract
A leg exerciser is for use by a person sitting in a chair. The device is located in front of the chair and the user puts his feet onto two boards which are at an acute angle to the horizontal. A mechanism including a drive motor or flywheel inside the device rocks the boards anti-phase about a horizontal axis lying transverse to the feet between acute angle positions. Sections of the boards lift out of and back into the planes of the boards during each cycle of rocking to lift and lower the user's toes relative to the remainder of the feet so that the feet are subjected to exercise movements similar to walking movements. The exerciser drives the leg blood pump with a view to improving the user's leg circulation.
Claims7
An exercise machine for the leg and foot comprising
- (a) a casing adapted to stand on the floor,
- (b) means defining a horizontal rocking axis in the casing,
- (c) a footboard positioned to receive the foot in a predetermined position and mounted on said rocking axis for rocking movement,
- (d) means limiting the rocking of the footboard on said rocking axis between first and second acute angle positions,
- (e) a sub-board defined in said footboard at a forward end thereof in the region where the user's big toe is to be located, said subboard being displaceable relative to the plane of the footboard,
- (f) a push rod connected to the underside of said sub-board, and
- (g) means effecting pushing of said rod and displacement of said sub-board upwardly relative to the plane of the footboard as the footboard rocks from the first and greater acute angle position to the second and lesser acute angle position to articulate the user's big toe relative to the foot while the foot is articulated relative to the leg by the rocking of the board, whereby simulated walking movements of the foot and toe are effected by the machine.
