ABSTRACT:
A portable, manually adjustable work station (10, 60) for use on a support surface. The work station (10, 60) includes a frame assembly (12) and a platform member (18, 68). The frame assembly (12) has a base portion (14, 72) and a support portion (16, 70) extending vertically from the base portion (14, 72). The work station (10, 60) further includes a mounting assembly (30, 80) cantilever mounting the platform member (18, 68) to extend from at least one side of the support portion (16, 70) in several elevated positions relative to the base portion (14, 72). The mounting assembly (30, 80) is formed for movement between the elevated positions upon unweighting and tilting of the platform member (18, 68), and for automatic securing of the platform member (18, 68) in a selected elevated position upon rotating in the reverse direction and weighting of the platform member (18, 68). The base portion (14, 72) extends laterally from the support portion (16, 70 ) by an amount sufficient to support the platform member (18, 68) in a stable elevated position over the support surface with a person standing at any location on the platform member (18, 68). An adjustable and movable support assembly (66), preferably in the form of a seat support (88), also may optionally be mounted to the platform (18, 68).
