Combined leg press/leg extension machine

摘要

A multiple-exercise station may be used alone or as a station for a multi-gym type of exercise machine. The station has a frame supporting a bench for performance of leg presses and leg extensions. A user standing on the floor at one end of the bench may also perform standing leg curls. Two movable arms are attached to the frame at the one end of the bench. A first movable arm is pinned near the floor, having a plate attached to an upper end for placement of the feet of a user thereagainst. The first movable arm is rotated by the force of a user's legs, moving away at its upper end from the bench in response to a pressing action against the plate. A second movable arm is pinned at its top end to an aperture proximate the top of the first movable arm on the side opposite the bench. The lower end of the second movable arm is rotatable away from the first movable arm. A padded crossbar is attached to the bottom end of the second movable arm for engaging the back of the ankle of a user performing standing leg curls or for engaging the front of the ankle of a user performing sitting leg extensions. A cable attached to a resistance is reeved in a block and tackle arrangement around a first pulley mounted to the second movable arm and other pulleys mounted to the frame. When either the first or the second movable arm is rotated away from the frame, the appropriate resistance is provided by the cable acting on the first pulley to resist the motion.
