Abstract
The present invention relates to a standup exercise apparatus that simulates walking and jogging with arm exercise. More particularly, the present invention relates to an exercise machine having separately supported pedals for the feet and arm exercise coordinated with the motion of the feet where the pedal stride length is determined by the movements of an operator.
Claims19
An exercise apparatus comprising;
- a framework, said framework configured to be supported on a generally horizontal surface;
- a pair of crank arms, said crank arms being connected to rotate about a pivot axis on said framework;
- a pair of foot support members, each said foot support member having a foot engaging pedal attached;
- a pair of first support links, each said first support link having a first end pivotally connected to a respective said crank arm and a respective said foot support member;
- a pair of second support links, each said second support link pivotally connected to a respective said foot support member and to a stationary pivot on said framework;
- a pair of handles for arm exercise, each said handle pivotally connected to said framework;
- a pair of connector links, each said connector link pivotally connected to a respective said handle and to a respective said first support link;
- a crossover assembly, said crossover assembly operably associated with said handles to cause one said handle to move in a direction opposed to the other said handle;
- said pedals configured to move relative to said framework when the foot of an operator is rotating said crank arms whereby said pedals follow an elongate curve path wherein the stride length of said elongate curve path is determined by the movement of said operator.

- a pair of handles for arm exercise, each said handle pivotally connected to said framework;
- a pair of connector links, each said connector link pivotally connected to a respective said handle and to a respective said first support link;
- a crossover member, said crossover member pivotally connected to said framework intermediate the ends of said crossover member;
- a pair of crossing links, each said crossing link pivotally connected to one end of said crossover member and to a respective said handle such that forward movement of one said handle causes the rearward movement of the other said handle;
- said pedals-configured to move relative to said framework when the foot of an operator is rotating said crank arms whereby said pedals follow an elongate curve path wherein the stride length of said elongate curve path is determined by the movement of said operator.

An exercise apparatus comprising;
- a framework, said framework configured to be supported on a generally horizontal surface;
- a pair of crank arms, said crank arms being connected to rotate about a pivot axis on said framework;
- a pair of foot support members, each said foot support member having a first portion, a second portion and a foot engaging pedal;
- a pair of first support links, each said first support link having a first end pivotally connected to a respective said crank arm and a respective said foot support member to cause said first portion of said foot support member to have a generally up and down movement;
- a pair of second support links, each said second support link pivotally connected to a respective said foot support member and to a stationary pivot on said framework to cause said second portion of said foot support member to have a generally back and forth movement;
- a pair of handles for arm exercise, each said handle pivotally connected to said framework intermediate said pivot axis and said second support links;
- a pair of connector links, each said connector link pivotally connected to a respective said handle and to a respective said first support link;
- a crossover assembly, said crossover assembly operably associated with said handles to cause one said handle to move in a direction opposed to the other said handle;
- said pedals configured to move relative to said framework when the foot of an operator is rotating said crank arms whereby said pedals follow an elongate curve path wherein the stride length of said elongate curve path is determined by the range of movement of said handles.
