Abstract
A counterbalancing mechanism allows a weight or constant force to be counterbalanced for any practical linear range of travel, including means for effortlessly adjusting the mechanism for a constant force or load of any practical magnitude. A load support slides along an axis substantially passing through a fixed lower pivot point. The load support member is pivotally connected to the top end of an upper lever arm. The upper lever arm is pivotally connected by a horizontal link to the upper end of a lower lever arm that is pivotally connected to the fixed point. A pully that may swivel about its swivel axis embraces the axis and guides a cable connected to the horizontal link at one end to a spring assembly at the other end. The spring assembly may be adjusted.
