Abstract
Abstract An exercise apparatus includes a crank rotatably mounted on a frame, and an axially extending support connected to the crank at a radially displaced location. Both a force receiving member and a discrete support member are linked to the axially extending support in such a manner that rotation of the crank relative to the frame is linked to movement of the force receiving member in a generally elliptical path relative to the frame.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
76 words
On an exercise apparatus of the type having left and right foot supports movably interconnected between a frame and respective left and right cranks for movement through respective elliptical paths, the improvement comprising left and right rails; wherein each said foot support is rollably mounted on a respective rail: left and right cables that link rotation of the cranks to amplified displacement of the foot supports in relation to a crank diameter defined by the cranks.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
250 words
An exercise apparatus, comprising: a frame designed to rest upon a floor surface; a first left pin mounted on a left side of the frame, and a first right pin mounted on an opposite, right side of the frame; a left crank and a right crank, wherein each said crank is rotatably mounted on the frame and rotatable about a common crank axis; a second left pin mounted on the left crank, and a second right pin mounted on the right crank, wherein the second left pin and the second right pin cooperate to define a crank diameter; a left rail and a right rail, wherein a first end of the left rail is rollably supported on one said left pin, and an opposite, second end of the left rail is pivotally connected to the other said left pin, and a first end of the right rail is rollably supported on one said right pin, and an opposite, second end of the right rail is pivotally connected to the other said right pin; a left foot support and a right foot support, wherein each said foot support is rollably mounted on a respective rail; and a left cable assembly and a right cable assembly, wherein each said cable assembly links rotation of a respective crank to movement of a respective foot support through a generally elliptical path having a first axis that is longer than the crank diameter, and an orthogonal, second axis that is shorter than the crank diameter.
