Abstract: An equapoised arm assembly is counterbalanced by springs enclosed within tubes that are components of the arm assembly. The arm assembly has a lower pair of parallel arms which are pivoted at their lower ends to a swivel bracket that turns about a vertical axis in a fixed bracket. Each of these arms is pivoted at its upper end to a floating bracket that is pivoted to a similar upper pair of parallel arms. An article support bracket is mounted upon the other end of the upper pair of arms and may include a universal joint assembly. The arms are tubular and each pair forms a parallelogram by virtue of the pivotal connections with the respective brackets. A coil spring is enclosed within one arm of each pair of arms to exert a counterbalancing effect upon its pair of arms. A nylon shoe is connected to at least one end of each spring and is slidable within the tube.
