ABSTRACT:
Two arm sections are interconnected by a connection to provide an articulated arm. The connection includes mating gear wheels with one such wheel on each of the two arms. The connection also includes side pieces for providing a fixed distance between the respective axes of the gear wheels. The side pieces include an extension which constitutes a lever. As the angle between the sections of the articulated arm, varies the lever moves to increase or decrease the tension in a spring that counterbalances the varying forces on the articulated arm.
