ABSTRACT:
A calf exercising machine which utilizes a frame-journaled rotating foot-engaging assembly, which rotates about an axis which is approximately common with the axes of rotation of the operator's ankle joints, to apply resistive force to the balls of an operator's feet through circular paths about the axes of rotation of the operator's ankle joints. The machine fixes the positions of the operator's ankle joints, through the use of body-machine contact surfaces which apply constraining forces to the operator's body, which balance the components of force applied at the ball-of-the-foot-engaging force-transmitting contact surfaces, throughout the range of the exercise movement. A second rotating body, which contains provision for loading weight onto, is journaled to the machine's frame and is mechanically linked to the rotating foot-engaging assembly. Together, these two rotating bodies, the link joining them, and the frame of the machine form a 4-bar linkage, which acts in conjunction with the rotating weight arm, to vary the resistive force applied to the balls of the operator's feet, throughout the exercise movement.
