Abstract
A height-adjustable column has a stationary tube that receives a height-changing mechanism, such as a pneumatic spring having a cylinder and a rod that are axially movable with respect to one another. A transmitting mechanism includes a movable member that is operatively associated with the rod and is movable in a direction opposite to the direction of movement of the cylinder upon extension of the pneumatic spring when the pneumatic spring is in a predetermined lift zone.
