Abstract
The invention is a readily adjustable work station. The invention includes a manual or machine driven linkage for adjusting the vertical position of a work station top surface in a level manner. This linkage includes rack and gear sets associated with movable supporting columns that support the work station top surface and a rotational transfer means that ensures that rotational energy from a driving means is evenly imparted to the rack and gear sets. Alternatively, the mechanical linkage may comprise ball plunger screws rather than rack and gear sets. The invention also includes an apparatus for manually adjusting the angular orientation of the work station top surface, and an apparatus for adjusting the clearance between the stationary support structure and the movable support structure.
