Abstract:
A height-adjustable workstation main frame includes a pair of telescoping, adjustable legs and a rigid yet efficient fixing frame carried by the upper portions of the legs to provide lateral stability, increased weight bearing capacity and functional flexibility. The same telescoping leg structure is adaptable to receive a motor drive, a manual crank lift or a manually adjusted mechanism for establishing the desired height of the table top. Fore and aft stability is increased by the shape and interengagement of the telescoping inner and outer leg weldments and the use of duplicate, laterally aligned bearing slide assemblies interconnecting the inner and outer leg weldments of each telescoping leg.
