ABSTRACT:
A manually controlled actuating device is provided to assist in overcoming forces, which resist adjustment of the device into certain positions, and at the same time minimize operator fatigue. The device includes a shaft adjustably mounted for movement from a predetermined rest position along a fixed path and having a spring-biased multiple-input-accepting handle attached to one end of the shaft. The handle is adapted to accept push, pull and squeeze inputs. Disposed adjacent the other end portion of the shaft and in proximity to the shaft's path of movement are a pair of fixedly mounted cam plates having the surfaces thereof adapted to be engaged by a follower pin carried by the shaft. The follower pin is mounted on the shaft for limited movement longitudinally thereof and is interconnected to the handle whereby application of one of the input forces on the handle will effect movement of the follower pin relative to the cam surfaces and permit controlled movement of the shaft from the predetermined rest position. As the shaft moves along its path from the rest position, the follower pin simultaneously follows the cam surfaces. Any longitudinal displacement of the follower pin by the cam surfaces in a direction away from the handle causes increased energization of the handle biasing spring. Upon release of the handle, the shaft will return to the rest position due to the increased energy of the biasing spring being released through the follower pin onto a segment of the cam surfaces causing a force vector to be established overcoming any resistance normally encountered by the shaft in returning to its rest position.
