Abstract
A parallelogram bracket assembly with a force balance mechanism which utilizes a pneumatic spring situated in the parallelogram bracket assembly. The pneumatic spring has a cylinder receiving a piston which has a piston rod and the cylinder is supported against parts connected to one articulated axle and an end of the piston rod is supported against parts which are connected to an articulated axle diametrically arranged to the one articulated axle. According to the invention, one of the rod members forming the parallelogram bracket assembly has a tubular guide channel for the telescopic acceptance of the pneumatic spring in a manner to allow an easy interchangeable fashion. For easy replacement of the pneumatic spring, an end piece is connected to the articulated axle and is releasably held at least at one end of the guide channel and the piston rod or the cylinder presses against this end piece.
