Abstract

The present invention relates to a standup exercise apparatus that stimulates in-place jogging and climbing with elliptical 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. A linkage is provided for each foot pedal to guide the pedal with reciprocating motion wherein the toe of the foot moves faster than the heel of the foot. A pair of cranks operably associated with the pedals provide dependent pedal motion. Handle movement is coordinated with the pedal movement for total body crosstraining. Low knee stress allows long duration exercise without hurting knees common with some crosstrainers.

Claims

1. An exercise apparatus comprising:

a frame, said frame configured to be supported by a supporting surface;

a pair of linkages, each said linkage comprising a plurality of links operably associated with said frame;

a pair of foot support members, each foot support member having a foot engaging pedal and being operably associated with a corresponding said linkage;

a pair of cranks, each said crank configured to rotate about a common axis connected to said frame;

a pair of handles links, each said handle link pivotally connected to a corresponding said crank and said foot support member;

each said linkage configured to guide said pedal relative to said frame with reciprocating movement along inclined arcuate non-elliptical paths as the foot of a user rotates said cranks whereby the toe of said foot is higher than the heel of said foot during the upper portion of said arcuate paths and said toe of said foot is below said heel of said foot during the lower portion of said arcuate paths.

2. The exercise apparatus according to claim 1 further comprising a pair of handles, each said handle operably associated with corresponding said handle link whereby said handle provides arm exercise.

3. The exercise apparatus according to claim 2 wherein said handle further comprises a hand grip whereby said hand grip follows an elongate curve path.

4. The exercise apparatus according to claim 1 further comprising a flywheel, said flywheel operably associated with said cranks.

5. The exercise apparatus according to claim 1 further comprising a load resistance, said load resistance operably associated with said cranks.

6. An exercise apparatus comprising:

a frame, said frame configured to be supported by a supporting surface;

a pair of linkages, each said linkage comprising a plurality of links operably associated with said frame;

a pair of cranks, each said crank configured to rotate about a common axis connected to said frame;

a pair of foot support members, each said foot support member having a foot engaging pedal and being operably associated with a corresponding said linkage and said crank;

each said linkage configured to guide said pedal relative to said frame with reciprocating movement along inclined arcuate non-elliptical paths as the foot of the user rotates said cranks whereby the toe of said foot moves faster than the heel of said foot along a portion of said arcuate paths.

7. The exercise apparatus according to claim 6 further comprising a pair of handle links, each said handle link pivotally connected to a corresponding said foot support member and said crank.

8. The exercise apparatus according to claim 7 further comprising a pair of handles, each said handle operably associated with a corresponding said handle link whereby said handle provides arm exercise.

9. The exercise apparatus according to claim 8 wherein said handle further comprises a hand grip whereby said hand grip follows an elliptical curve path.

10. The exercise apparatus according to claim 6 further comprising a flywheel, said flywheel operably associated with said cranks.

11. The exercise apparatus according to claim 6 further comprising a load resistance, said load resistance operably associated with said cranks.

12. An exercise apparatus comprising:

a frame, said frame configured to be supported by a supporting surface;

a pair of first pedal links, each said first pedal link pivotally connected to said frame;

a pair of second pedal links, each said second pedal link pivotally connected to said frame;

a pair of foot support members, each said foot support member having a foot engaging pedal and being pivotally connected with corresponding said first and said second pedal links;

a pair of cranks, each said crank configured to rotate about a common axis connected to said frame and operably associated with a corresponding said foot support member;

said pedals configured to reciprocate relative to said frame along inclined arcuate paths when the foot of the user is rotating said cranks whereby the toe curve of said foot has a slope different from the heel curve of said foot.

13. The exercise apparatus according to claim 12 further comprising a pair of handle links, each said handle link pivotally connected to a corresponding said foot support member and said crank.

14. The exercise apparatus according to claim 12 further comprising a pair of handles, each said handle operably associated with said corresponding pedal whereby said handle provides arm exercise.

15. The exercise apparatus according to claim 14 wherein said handle further comprises a hand grip whereby said hand grip follows an elongate curve path.

16. The exercise apparatus according to claim 12 further comprising a flywheel, said flywheel operably associated with said pedals.

17. The exercise apparatus according to claim 12 further comprising a load resistance operably associated with said pedals.
