Abstract
A pulley assembly for removably fastening an arm cord to an exercise apparatus is disclosed. The pulley assembly includes a yoke having a central portion and a pair of parallel leg portions, the central portion having a bore therethrough, a pulley wheel rotatably supported between the yoke leg portions by an axle, and an elongated stem having an axially extending shaft portion protruding through the bore. The shaft portion has distal end portion having an L shaped slot formed therethrough. The L shaped slot forms a hook shaped end to the shaft portion. A tapered coil spring over the shaft portion of the stem, has a small end and a large diameter around the shaft portion of the stem. The spring biases the hooked end away from an eyebolt on the exercise apparatus to keep the pulley assembly engaged with the eye bolt and hence fastened to the exercise apparatus.
