Abstract

Abstract A multiple rigid bar mechanism serving as an exercise machine which may be characterized as providing a motion path along a closed curve. In the simplest embodiment, the mechanism comprises a motion bar rotatably connected to a flywheel and a trunnion element. The flywheel is rotatably secured to the machine frame about a flywheel base joint, and is eccentrically connected to the motion bar at a flywheel motion bar first joint. Upon input force from the machine operator at a motion bar force input region, the motion bar will be caused to pivot about a motion bar trunnion region thus effecting the motion bar first joint to translate at an eccentric radius about the flywheel or crank rotational axis. The mechanism may be used to exercise the operators upper and/or lower body, and may be described as having a reciprocating type of resistive motion with inertial characteristics of a flywheel.

Claims Analysis

Total Claims: 21
Claim 1
Independent Claim 147 words
An elliptical motion exercise apparatus, comprising: a frame designed to rest upon a floor surface; a crank member mounted on said frame and rotatable about an axis relative to said frame; a force receiving member having a first portion configured for engagement by a person, and a second portion rotatably connected to said crank member at a point radially displaced from said axis; a guide member connected to said frame and operative to direct a third portion of said force receiving member through a reciprocal path as said crank member rotates, wherein said first portion of said force receiving member is directed through a generally elliptical path as said crank member rotates; and a variable length member interconnected between said frame and one of said force receiving member and said guide member, wherein said variable length member resists movement of said guide member relative to said frame.
Claim 2
Dependent Claim 147 words
An elliptical motion exercise apparatus, comprising: a frame designed to rest upon a floor surface; a crank member mounted on said frame and rotatable about an axis relative to said frame; a force receiving member having a first portion configured for engagement by a person, and a second portion rotatably connected to said crank member at a point radially displaced from said axis; a guide member connected to said frame and operative to direct a third portion of said force receiving member through a reciprocal path as said crank member rotates, wherein said first portion of said force receiving member is directed through a generally elliptical path as said crank member rotates; and a variable length member interconnected between said frame and one of said force receiving member and said guide member, wherein said variable length member resists movement of said guide member relative to said frame.
Claim 3
Dependent Claim 16 words
