Abstract

The outer and top square tubular section of the telescopic upright has a hydraulic jack for automatic height-adjustment. The top of the hydraulic jack is fixed to the top tubular section by means of a threaded manual adjustment rod. The bottom of the jack has an insulating joint through which passes the rod which is joined to the upright's base and which has a fluid discharge piston at the top. The top of the jack has a gap filled with air, connected to the bottom of the jack by holes, some of which are fitted with valves.
