A portable or operable wall system utilizing wall panels defining a wall or partition extending between a floor surface and a ceiling surface with the portable wall system including wall panels which are completely separable from the ceiling surface and includes lower support means for movably supporting the panels on a floor surface to facilitate movement of the panels to a desired location. The operable wall system includes ceiling trackways which suspend the panels to enable movement to a desired location. Both wall systems include an adjustable, spring biased, inverted channel-shaped member engageable with the ceiling surface and a vertically extendible and retractable channel-shaped floor engaging member which enables the effective vertical height of the panels to be altered between an extended position in which the panels sealingly engage the floor surface and ceiling surface and a retracted position of lesser vertical dimension than the floor to ceiling height to enable the panels to be movably supported on the floor surface for movement while in generally vertical position to a desired location in the portable wall system and for suspended support from an overhead trackway for movement to a desired location in the operable wall system. |
