ABSTRACT:
A portable wall system utilizing portable wall panels defining a wall or partition extending between a floor surface or other lower surface and a ceiling surface or other overhead surface. The portable wall panels each include lower support means for movably supporting the panels on a floor surface to facilitate movement of the panels to a desired location. The upper edge of each panel is provided with a spring biased ceiling or overhead surface engaging member and the lower edge of each panel includes a vertically extendible and retractable floor surface engaging member so that the wall panels will form a complete partition between the floor surface and ceiling surface and be easily installed, removed or released and relocated. The side edges of the wall panels are constructed for inter-engagement with similar panel modules or wall mounted receptors.
