Vertically adjustable work station assembly

Image Number 3 for United States Patent #5158157.

A vertically adjustable work station for use proximate a conveyor belt or the like. The work station includes a platform with side rail assemblies that is mounted for vertical displacement to ground engaging support posts. The posts are telescoped inside the rail assembly and a displacement assembly is provided to raise and lower the platform on the posts. In one embodiment, the posts are externally threaded and belt-driven gear nuts are mounted on the posts and carry the platform. In another embodiment, the posts and side rails are formed to provide a fluid piston-cylinder assembly. In a final embodiment, a pneumatic constant force spring biases the rail assembly and platform upwardly from the posts, and a brake assembly is used to hold the platform at the desired elevation.
