Abstract
A height-adjustable support arm with a parallelogram linkage has a stationary first articulated head and a second articulated head which is movable relative thereto, the second articulated head having a support bar connected thereto for mounting a device such as a hanging lamp. In order to avoid gaps in the exterior portion of the second articulated head, the movable parts thereof are surrounded by a flexible covering mounted on a tubular parallelogram leg at one end and at the free end of the support bar at its other end. The exterior dimensions of the covering correspond substantially to the tubular parallelogram leg and the interior dimensions are selected such that the second articulated head can move freely therein within an adjustment range.
