ABSTRACT:
A climbing mechanism is disclosed that comprises a central upright post with right and left foot pedal assemblies slidably disposed on right and left lateral sides of the post. Each pedal assembly is attached to a wedge-shaped slider that travels within a complementary shaped channel lengthwise of the post. Each pedal includes a foot-supporting sole portion and has a foot restraining strap. User-controlled pivoting of the pedals controls the mechanism that locks the pedals with respect to the post. Illustrative embodiments describe locking and unlocking arrangements wherein a projecting member affixed to each pedal assembly (such as a tooth or a cambered element) is controllably mated with a selected one of a plurality of sockets or recesses located lengthwise of the post. A further embodiment describes a locking and unlocking arrangement in which a braking member on each pedal assembly selectively positions each assembly through controllably gripping a cable disposed lengthwise of the post. Tension springs are included to urge the pedal into locked positions on the post. Adjustable crosspieces located at the top and bottom of the post provide support and footing. The device can optionally be constructed in take-apart form, with post segments joined together by coupling elements.
