ABSTRACT:
The invention relates to a partition wall movable in an opening and consisting of double-walled panels coupled pivotally to each other at the standing edges, alternate panels being formed with a guide member attached fixedly to the panel and displaceable along a rail extending above the panels. An extension device in the form of a pin-like body which is slidable in an upper rail and which is continuously loaded by a force directed towards one of the standing hinged edges is provided. The partition wall is distinguished in that on the hinge edges two or more hinge assemblies are arranged, each provided with at least three parallel hinge pins and in each case with a pair of wings associated with each hinge portion. The partition wall further includes a panel wall whereby between the walls of each panel spacer elements are arranged.
