摘要

A display device comprising a tube INTERIOR (10) SWINGING TO THE FLOOR IN "P" and carrying an outer tube (12) for moving TELESCOPICO. INSIDE THE TUBE EXTERIOR FITTING end carries a collar (14) pivotally connected to an actuator arm or RADIAL (18) pivoting toward the ground "Q". The radial arm (18) carries a drive plate (50) defining a path CAM IN WHICH RUNS A cam follower. The mechanism is actuated by a cam (20). Acting Lever (20), rotation consequently a drive plate on the joint collar (14) Executes INITIALLY SCHEDULED A outer tube (12) about its longitudinal axis rotation and then locks the outer tube against rotation. Then the outer tube (12) extends telescopically IN CONNECTION WITH inner tube and the inner tube pivots on "P".
