GAS LIFTER OF A MULTI-STAGE OF AN OPEN ARCHITECTURE, CAPABLE OF PROVIDING A VARIETY OF OPEN HEIGHTS

摘要

PURPOSE: A gas lifter of a multi-stage of an open architecture is provided to ensure the safety of a user and to enhance user satisfaction since the open heights of a tail gate can be adjusted and thus are adaptively open to a variety of user heights.;CONSTITUTION: A gas lifter of a multi-stage of an open architecture comprises a cylinder(200), a piston rod(205), a piston(230) and a stopper(220). The cylinder comprises first and second grooves, which form the moving path of the gas. The piston rod linearly moves back and forth along the whole length of the cylinder in the cylinder. The piston is coupled to the leading end of the piston rod, which is located in the cylinder. The stopper is installed so that its position is fixed in the cylinder by a coupling protrusion. The stopper is installed so that its central part is penetrated by the piston rod. The stopper makes contact with one surface of the piston when the whole length of the gas lifter is extended.;COPYRIGHT KIPO 2011
