Abstract

An exercise apparatus having foot beams (38a, 40a) rotatably mounted to an upright post member (140a) of a frame to rotate about a first axis (322). Hand levers (132a, 134a) are secured to pivot members (152a) pivotally mounted to the upright post member to rotate about a second axis (328). The hand levers are coupled by resilient linkage members (380) including elastomeric joints (382) to the foot levers so that as each foot lever rotates about the first axis, the corresponding hand lever normally rotates a related distance about the second axis. The linkage members are resiliently deformable to allow discontinuity between the rotation of the foot levers and hand levers when an exerciser exerts a differential force on the hand levers relative to the corresponding foot levers.

Dependent claims

An exercise apparatus comprising:

a frame;
a first lever for an exerciser to exert resistance against, said first lever rotatably mounted on the frame to rotate about a first axis;
a second lever for an exerciser to exert resistance against, said second lever rotatably mounted on the frame to rotate about a second axis;
and
linkage means for coupling the first lever to the second lever so that as the first lever rotates about the first axis the second lever is normally caused to rotate a proportional distance about the second axis, the linkage means being reversibly deformable to enable the first and second levers to rotate relative to each other by an amount other than the proportional distance when a user exerts differential resistance to rotation of the second lever relative to the first lever, wherein the linkage means includes an elastomeric joint member.
