Multi-hip exerciser
TLDR
In this article, an exercising machine with an adjustable actuator arm assembly coupled to a weight stack by a pulley/cable assembly is described, which can be rotated through an arc to provide a number of operating locations.Abstract:
An exercising machine that has an adjustable actuator arm assembly coupled to a weight stack by a pulley/cable assembly. The actuator arm assembly includes an actuator arm that lifts the weight stack when rotated through an arc. The machine is constructed with a frame that has a vertical bar. The actuator arm is coupled to a sleeve assembly that can slide along the vertical bar, to provide a number of operating locations. The machine also has a first cable that is coupled to the actuator arm. The cable is looped around a first tension pulley, a first floating pulley and then fixed to the sleeve assembly. The first floating pulley is coupled to a second cable that loops around a second tension pulley and is attached to the weight stack. When the actuator arm is rotated, the first floating pulley is pulled in a downward direction. The movement of the first floating pulley pulls the second cable and lifts the weight stack in an upward direction. When the sleeve assembly is adjusted to a new position on the vertical bar, the cable lengths between the first tension pulley and actuator arm assembly, and between the first floating pulley and sleeve, change an equal and offsetting amount.read more
