摘要： The spring counterbalanced boom suspension system is designed for suspending a viewer for use in a visual virtual environment system. The spring counterbalanced boom suspension has an improved range of motion which allows for fully counterbalanced movement of the viewing device to a vertical positions, and to horizontal positions on either side of the vertical. The viewer is suspended by a counterbalanced boom arm which is in turn supported by a cantilever arm pivotably and rotatably connected to a support structure. A tension spring is connected between the support structure and an attachment point on the cantilever arm by a cable for counterbalancing the weight of the viewing means and the boom arm. The spring tension and preload are adjusted to the geometry and counterbalancing weight of the suspension system, and the cantilever arm is capable of a fully counterbalanced range of motion. A pair of pulleys are preferably mounted to the upper end of the support structure to provide a channel through which the cable passes.
