Multi-function exercise system

摘要

A multi-function exercise system (10) for reversibly displacing weight elements (12) in a substantially vertical direction (14) responsive to a rotative displacement force applied to the actuating arm assembly (38) from an initial position in either of two opposite directions. The exercise system (10) includes a transforming mechanism (100) displaceably coupled to a base frame (18) in order to accommodate the user applying the rotative force to the actuating arm assembly (38). The transforming mechanism (100) includes a rotative displacement member (102) rotatively coupled to the actuating arm assembly (38). Rotative displacement member (102) is coupled to a linear displacement member (104) by a pair of flexible chain members (108) and (110), coupled to opposing sides of rotative displacement member (102). Linear displacement member (104) is slidably coupled to displaceable frame assembly (106) for displacement in an identical direction regardless of the displacement direction of the actuating arm assembly (38) from an initial predetermined position. The linear displacement member (104) is coupled to the weight elements (12) by force transmission mechanism (30). Force transmission mechanism (30) and transforming mechanism (100) are coupled to a vertical adjustment assembly (40) for compensating for the selective positional displacement of transforming mechanism (100).
