Patent ID: 7530930

Claim:
An exercise apparatus comprising: a frame adapted to rest on a surface, the frame including a front end, a rear end, a front region, and a rear region, the rear region having two tracks extending longitudinally; a rotating assembly mounted on the front region of the frame, the rotating assembly having two opposite connecting points moving along a circular path, and the distance between the bottom of the circular path and the tracks is smaller than 10 cm; a flywheel mounted pivotally on the front region of the frame and connected to the rotating assembly, the flywheel being rotatable simultaneously with the connecting points; left and right supporting rods respectively having a front end, a rear end, and a supporting member therebetween, the respective distance between the front ends and the corresponding rear ends of the supporting rods being greater than the diameter of the circular path and smaller than two times diameter of the circular path, the supporting member located between the rear end and the middle of the supporting rod, the front ends of the supporting rods connected pivotally to the connecting points respectively, the rear ends of the supporting rods moving along the track between a front point and a rear point so as to cause the supporting member to move along an arcuate closed path, therefore in the longitudinal direction, the front edge of the closed path aligns transversely or is in back of the rear edge of the circular path, and the longitudinal horizontal distance between the front edge of the closed path and the rear edge of the circular path is smaller than 20 cm; left and right swing arms each having a pivot point connected to the front region of the frame, and a swing end located below the pivot point for moving back and forth; left and right links each having a front end and a rear end, the front ends respectively pivotally connected to the swing ends of the swing arms; and left and right pedals connected respectively to the rear ends of the links and located behind the corresponding supporting members of the supporting rods, the left and right pedals further connected pivotally to the supporting members; wherein, in the longitudinal direction, the front point of the track aligns transversely or is in back of the front edge of the motion path of the front ends of the pedals, and the rear point of the track aligns transversely or is in front of the rear edge of the motion path of the rear ends of the pedals.
