Abstract:
A pull down exercise apparatus, comprising:a base member for supporting the apparatus on a horizontal plane and defining a first vertical plane normal thereto and a second vertical plane orthogonal to the first;a support member extending from the base member;a pair of four-bar linkage mechanisms supported by the support member, the pair of four-bar linkage mechanisms each including a primary lever arm pivotable about a primary axis and a follower lever arm pivotable about a secondary axis, the primary axes being disposed at an angle with respect to each other and to the second vertical planet, such that the lower end of the primary axes are tilted inwardly toward each other and the second vertical plane, the primary and follower lever arms lying in a common plane tilted at an angle relative to the first vertical plane;a handle operatively associated with each of the four-bar linkage mechanismsa weight mechanism operatively associated with the pair of four-bar linkage mechanisms for resisting; andwherein the primary and follower lever arms travel in the common plane as the pair of four-bar linkage mechanisms are displaced between a first position and a second position while maintaining a correct biomechanical positioning.
