Abstract

A work station which has a work table top (30) in truncated "U" shape with end panels (32) and a rear panel (34) each having height adjusting angular legs (38) and (40). A pair of side skirts (36) are abutted against the panels enclosing one side of the work station. The height is adjusted by linear actuators (44) attached between the legs and panels controlled electrically, allowing a physically challenged or developmentally disabled person to utilize the work station while sitting in a wheelchair with the ability to adjust the height to an optimum level. Other embodiments provide manual adjustment of the height and platform enclosures (88), (98) and (102) mounted on top of the work station allowing material placed thereupon to be at a convenient angular position relative to the work table top (30).
