Abstract
A stationary exercise device with flexible support elements may include a frame with a base portion. A crank system with crank arms is coupled to and supported by the frame. Right and left pivotal linkage assemblies may each have an arcuate motion member and a foot support member. The arcuate motion member may be coupled to the frame. The foot support member may be coupled to the arcuate motion member. The arcuate motion member may be oriented in a generally vertical position and the foot support member may be oriented a generally horizontal position. Flexible element coupling systems couple the right and left foot support members to the crank system.
Claims30
A stationary exercise apparatus comprising:
- a frame having a base portion adapted to be supported by a floor,
- a crank system comprising first and second crank arms, the crank system being supported by the frame,
- a right linkage assembly comprising a right arcuate motion member and a right foot support member coupled to the right arcuate motion member, the right arcuate motion member oriented in a generally vertical position during use, the right foot support member oriented in a generally horizontal position during use,
- a left linkage assembly comprising a left arcuate motion member and a left foot support member coupled to the left arcuate motion member, the left arcuate motion member oriented in a generally vertical position during use, the left foot support member oriented in a generally horizontal position during use, and
- first and second coupling systems each comprising a flexible element, the first coupling system coupling the first crank arm to the right foot support member and the second coupling system coupling the second crank arm to the left foot support member.

A stationary exercise apparatus comprising:
- a frame having a base portion adapted to be supported by a floor,
- a crank system comprising first and second crank arms, the crank system supported by the frame,
- a right linkage assembly comprising a right arcuate motion member and a right foot support member, the right arcuate motion member comprising a first portion and a second portion, the first portion being above the second portion and coupled to the frame, the right foot support member comprising a first portion and second portion, the first portion of the right foot support member being coupled to the second portion of the right arcuate motion member,
- a left linkage assembly comprising a left arcuate motion member and a left foot support member, the left arcuate motion member comprising a first portion and a second portion, the first portion being above the second portion and coupled to the frame, the left foot support member comprising a first portion and a second portion, the first portion being coupled to the second portion of the left arcuate motion member, and
- first and second coupling systems each comprising a flexible support element, wherein the first coupling system couples the first crank arm to the second portion of the right foot support member and the second coupling system couples the second crank arm to the second portion of the left foot support member,
- the right and left arcuate motion members being cross coupled so that motion of the right arcuate motion member causes an opposing motion of the left arcuate motion member.
