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.

Claims

1. A stationary exercise apparatus comprising:

a frame having a base portion adapted to be supported by the floor;

a crank system comprising first and second crank coupling locations, the crank system coupled to the frame;

a brake system coupled to the crank system and adapted to provide resistance to rotation of the crank system;

right and left linkage assemblies, each assembly comprising an arcuate motion member pivotally coupled to the frame and a foot support member pivotally coupled to the arcuate motion member at a location below the pivotal coupling to the frame, said foot support member oriented in a generally horizontal position; and

first and second coupling systems each comprising a flexible support element, said first coupling system coupling the foot support member of the right linkage assembly to the first crank coupling location, said second coupling system coupling the foot support member of the left linkage assembly to the second crank coupling location,

wherein the user may undertake a climbing motion causing continuous rotation of the crank system, and

wherein the user may also undertake a walking, striding, or jogging motion by applying forward and rearward forces to the foot support members while resistance is applied to the crank system by the brake system, the stride length of said walking, striding, or jogging motions being instantaneously variable by altering the forward and rearward forces applied to the foot support members.

2. The stationary exercise device of claim 1 wherein the right and left foot support members are cross coupled so that a forward or rearward motion of the right foot support member causes an opposing motion of the left foot support member.

3. The stationary exercise device of claim 1 wherein the crank system is operatively associated with means to inhibit at least one of the foot support members from settling in a top dead center position.

4. The stationary exercise device of claim 3 wherein said inhibiting means is a counterweight.

5. The stationary exercise device of claim 1 wherein said flexible support element is a belt, cable, or chain.
