ABSTRACT:
A vertically adjustable device for carrying a vise, an assembly platform or the like comprises a support tube which is vertically adjustably arranged within a guide tube arranged for attachment to a work bench or the like. In order to facilitate the vertical adjustment a gas spring is provided which acts between the support tube and the guide tube end exerts an upwardly directed force upon the support tube. The gas spring comprises a cylinder, a piston movable therein and a piston rod extending from the piston. The cylinder is arranged and held within the support tube so that upon removal of the support tube and the implement carried thereby by pulling the support tube out of the guide tube the gas spring is simultaneously removed leaving the work bench clear for other work.
