Filed:
May 18, 1990
Appl. No.:
7/524977
Inventors:
Richard W. Febey - Grayling MI
International Classification:
G05G 114
US Classification:

Abstract:
A pedal radius adjustment device comprised of a frame mounted onto the existing crank arm of a bicycle or similar exercise machine by a screw passing through the existing crank arm pedal mounting hole and attaching to the adjustment frame, and by a bracket mounted to the adjustment frame around the crank arm. The contact side of the frame is grooved to align with the pedal crank arm. The pedal is attached to a sliding block within the adjustment frame and is adjusted by a hand operated pull T-pin at multiple, known-radius, settings prearranged on the adjustment frame. In another embodiment, the T-pin is held in place by magnetic attraction between the T-pin and the sliding block.
