Abstract
A simulated stair climbing exercise apparatus having variable sensory feedback is provided. Sensory feedback, in the form of a lifting force acting on a lifting foot of the operator, varies with the operator's location in the stepping stroke. Maximum sensory feedback is provided at a lower portion of the stroke, minimum sensory feedback is provided at an upper portion of the stroke and maximum feedback at the lower portions. Sensory feedback is effected by means of direct interconnection of left and right foot mechanisms in combination with a spring. Direct interconnection is achieved by a cable routed around a series of pulleys such that a downward force on one foot mechanism results in an equal and opposite lifting force on the other foot mechanism. One of the pulleys is a floating pulley that is free to move and its positioned based upon the operating position of the stepping stroke. The spring is connected to the floating pulley such at 1) the direct interconnection cable controls the lifting force in the lower portion of the stroke, 2) the spring controls the lifting force at the upper portion of the stroke, and 3) a combination of the cable and spring control lifting force in the mid range.
