摘要： A resilient support column for height-adjustable chairs or the like includes a piston-and-cylinder type pneumatic spring that is installable in and removable from the column by means of a retaining sleeve structure carried by the spring. The retaining sleeve is connected to the column through a threaded connection that permits quick one-step insertion of the combined sleeve-spring unit into the column, while thereafter affording the advantage of threaded adjustment within the column or threaded removal therefrom. A simple mechanical fastener holds the retaining sleeve in place on the pneumatic spring during shipment and/or assembly.

摘要： A gas spring, having a collapse safety feature operable in the event of psure loss, is provided, for use, for example, as a counterbalance for flaps or vertically adjustable structures. A movable partition is arranged between the piston and the head of the cylinder of the gas spring, and is exposed on one side to a closed gas chamber under pressure, while on the other side the gas volume effecting the extension force of the piston rod is present between the piston and the partition. In event of pressure loss in the gas volume on either side of the piston, the movable partition will meet the piston and act as a safety to prevent abrupt release or lowering of the object for which the gas spring is to serve as a counterbalance.
