ABSTRACT:
An exercise apparatus having a frame (12,22,32), a pair of foot beams (38,40) pivotally mounted to the frame, and a pair of elastomeric torsion springs (100,102) for urging each of the foot beams toward an upper position. Each of the elastomeric torsion springs comprises an annular elastomeric member (110) having a central bore (112). An outer casing (104) surrounds and is attached to the exterior surface of the elastomeric member and an inner casing (114) is disposed within and attached to the side wall of the central bore. The inner casing of each spring surrounds and is attached to a support arm (42,44) extending out from the frame of the exercise apparatus, and the outer casing of each spring is received in and attached to the side wall of an aperture (120) in a foot beam. As the foot beam is caused to rotate relative to the frame, the elastomeric member is torqued. When weight is released from the foot beam, this torque urges the foot beam to rotate toward its nominal orientation until the torque is dissipated.
