Abstract
A counterbalancing assembly reduces the weight of an exercising person by pulling the exercising person upwardly. The counterbalancing assembly includes a monolithic support structure which is secured to a base. A cantilever support extends out from the top of the monolithic support structure. A cable extends from the top of the monolithic support structure, down through a linear actuator, and back up through the monolithic support structure to the cantilever support. The cable extends down from the end of the cantilever support to a position suitable for an exercising person to comfortably exercise on a piece of exercising equipment. A spring at the fixed end of the cable provides an unloading force accommodating to the exercising patient movement and dampens sudden movements created by the exercising person. A linear actuator is used to adjust the length of the cable extending down from the cantilever support and to tension the spring.
