Abstract

Claims (40)

1. An elliptical exercise machine comprising:

a first assembly comprising:

a first frame member;

a rotational resistance mechanism associated with the first frame member;

a first foot support member pivotally coupled to a portion of the rotational mechanism;

a second foot support member pivotally coupled to another portion of the rotational mechanism;

a second assembly pivotally coupled with the first assembly, the second assembly comprising:

a second frame member;

a first reciprocating arm pivotally coupled with the second frame member;

a second reciprocating arm pivotally coupled with the second frame member;

at least one folding assist mechanism coupled between the first assembly and the second assembly, the at least one folding assist mechanism configured to provide resistance to the second assembly as the second assembly rotates relative to the first assembly between a first, operating position and a second, folded position;

a rotational assist mechanism associated with the first assembly, the rotational assist mechanism including at least one lever arm configured to engage the ground and apply a moment to the elliptical exercise machine when at least a portion of the elliptical exercise machine is being lifted.

2. The elliptical exercise machine of claim 1 , wherein:

the first frame member, the rotational resistance mechanism, the first foot support member and the second foot support member maintain their operational relationships with each other while in both the first position and the second position; and

the second frame member, the first reciprocating arm and the second reciprocating arm maintain their operational relationships with each other while in both the first position and the second position.

3. The elliptical exercise machine of claim 2 , wherein the first foot support member is pivotally coupled the first reciprocating arm and wherein the second foot support is pivotally coupled with the second reciprocating arm.

4. The elliptical exercise machine of claim 3 , further comprising a plurality of support structures configured to support the elliptical machine in an upright storage position wherein the first frame member extends in a substantially vertical direction.

5. The elliptical exercise machine of claim 4 , wherein the first assembly includes a rear cross member coupled with the first frame member, wherein at least one support structure of the plurality of support structures is coupled with the rear cross member.

6. The elliptical exercise machine of claim 5 , wherein the first assembly includes a front cross member coupled with the first frame member and a handle coupled with the front cross member.

7. The elliptical exercise machine of claim 1 , wherein the at least one folding assist mechanism includes a damping mechanism.

8. The elliptical exercise machine of claim 1 , wherein the at least one folding assist mechanism has a first end pivotally coupled with the first frame member and a second end pivotally coupled with the second frame member.

9. An elliptical exercise machine comprising:

a first assembly comprising:

a first frame member;

a rotational resistance mechanism associated with the first frame member;

a first foot support member pivotally coupled to a portion of the rotational resistance mechanism;

a second foot support member coupled to another portion of the rotational resistance mechanism;

a second assembly comprising:

a second frame member coupled with the first frame member;

a first reciprocating arm pivotally coupled with the second frame member;

a second reciprocating arm pivotally coupled with the second frame member;

a rotational assist mechanism associated with the first assembly, the rotational assist mechanism including at least one lever arm configured to engage the ground on which the elliptical exercise machine rests and apply a moment to the first assembly when at least a portion of the elliptical exercise machine is being lifted.

10. The elliptical exercise machine of claim 9 , further comprising a plurality of support structures configured to support the elliptical machine in an upright storage position wherein the first frame member extends in a substantially vertical direction.

11. The elliptical exercise machine of claim 10 , wherein the first assembly includes a rear cross member coupled with the first frame member, wherein at least one support structure of the plurality of support structures is coupled with the rear cross member.

12. The elliptical exercise machine of claim 11 , wherein the first assembly includes a front cross member coupled with the first frame member and a handle coupled with the front cross member.

13. The elliptical exercise machine of claim 9 , wherein the first frame member is pivotally coupled with the second frame member such that the second assembly is pivotally displaceable relative to the first assembly from a first position to a second position.

14. The elliptical exercise machine of claim 13 , further comprising a folding assist mechanism coupled between the first assembly and the second assembly, the folding assist mechanism configured to provide resistance to the second assembly as the second assembly is displaced from the first position to the second position.

15. The elliptical exercise machine of claim 14 , wherein the folding assist mechanism includes at least one of a biasing member and a damping member.

16. The elliptical exercise machine of claim 9 , further comprising a locking mechanism associated with the first assembly configured to selectively engage the rotational assist mechanism and prevent the at least one lever arm from engaging the ground.

17. The elliptical exercise machine of claim 9 , wherein the at least one lever arm includes a first lever arm positioned on a first side of the rear resistance mechanism and a second lever arm positioned on a second, opposing side of the rear resistance mechanism.
