Abstract:
1. A mechanism for an elliptical exerciser comprising: a crank rotatably connected to a frame so as to have a free end rotatable in a circular path with respect to the frame; a restriction member rotatably connected to the frame so as to have a free end movable along an arcuate path; a transmission member having a first end rotatably connected to the restriction member, and a central portion rotatably connected to the crank, whereby the central portion of the transmission member moves along said circular path while the first end of the transmission member is constrained by the restriction member to move along a reciprocating arcuate path, such that a free end of the transmission member moves along an elliptical path; a reciprocating member having a first end rotatably connected to the transmission member, with a second end of the reciprocating member being operatively mounted to the frame, such that a reciprocating movement of the second end of the reciprocating member along the frame causes the first end of the reciprocating member to move along said elliptical path by the combined constraints of the crank, the restriction member and the transmission member; and a foot pedal connected to the reciprocating member, whereby the foot pedal moves along another elliptical path.
