ABSTRACT:
A traction sled exercise machine that provides two distinct exercise cycles, each of which employs bodily force to overcome gravity and elevate a body sled and user on an inclined frame supported rail from a point of origin to a point of destination. The structure and mechanics of this apparatus permits the user to confront machine resistance in a front or rear facing anatomical position. In either instance, arm force is extended through a block and tackle leveraging system, supplemented with leg pressure on one of two sets of adjustable foot stirrups provided for leg participation in the elevation task.
The body sled has a companion mechanism, called the force beam assembly, designed to help regulate machine resistance. In that assembly, the body sled is in pivotal connection with a force bar that carries a position adjustable, weighted hanger. The bar and hanger, in turn, are suspended in moveable fashion on a fulcrum mounted frame, wherein elevation of the sled produces oscillation of the frame and reciprocation of the bar and weighted hanger. That movement of force relative to the fulcrum reduces machine resistance during anatomically difficult phases of an exercise cycle. Also, overall increases or decreases in resistance may be obtained by repositioning the weighted hanger on the force bar.
