Abstract:
1. A foot pedal mechanism for an elliptical exerciser comprising: a frame; a pair of foot pedals adapted to each support thereon a foot of the user standing on the elliptical exerciser; a crank for each said foot pedal, each said crank being operatively connected to a respective one of the foot pedals such that a rotation of each said crank about an axis of rotation thereof causes a first motion restriction of the respective one of the foot pedals; and first linkages interconnecting said cranks to the frame such that at least the axis of rotation of each said crank is displaceable with respect to the frame and with the axes of rotation of the cranks being generally displaceable in opposite directions to cause a second motion restriction of the respective one of the foot pedals, a combination of said first and second motion restrictions resulting in the foot pedals being restricted to an elliptical path of motion, the cranks being interconnected to synchronize a displacement of the foot pedals with respect to one another along the elliptical path of motion.
