Abstract: A free-standing, prefabricated, knock down, readily assembled and disassembled, relocatable vertical wall or space divider. Such wall dividers are useful for partitioning buildings and/or office complexes. The wall is made up of a plurality of individualized and decorative flush panel units which are interchangeable and which are adapted to be readily inserted within quadrilateral openings delineated by a novel wall frame and locked into place by hidden spline members that are mounted in the wall frame for translatory movement. The wall frame is fabricated in a novel assemblage of unique components which can present either a metallic or wooden exterior finish surface. The configuration of the wall frame components provides for lateral walls to extend outwardly not only at modular locations but also from any other desired location by use of novel adapters. The panels may be removed, redecorated and replaced as needed. Shelving or other appurtenances are attachable to the hidden spline members.

Abstract: A shelf support bracket construction adapted for use singly or in pairs for engaging into a vertical wall divider or spline and having at least one rearwardly disposed projection and at least one forwardly disposed laterally offset projection for supporting an appurtenance. When used in pairs the brackets intermesh and the rearward projections of the brackets are vertically offset with respect to each other to engage in adjacent slots in the spline with the forward projections in horizontal alignment.

Abstract: A snubbing assembly for releasably securing a sheet of covering material to a wall panel module. The peripheral frame of the wall panel module is comprised of channels having a web wall and at least one side wall. The channels are disposed with the web wall facing inwardly of the module and with the side wall extending outwardly thereof. A longitudinal flange extends parallel with the side wall and is spaced laterally inwardly thereof to present a footed snub. Selectively movable gate means are carried by the channel to oppose the snub. An anchor means is secured to the marginal edge portion of the covering material and is releasably secured by the opposed interaction of the snub and gate means to maintain the covering material tautly upon the face of the wall panel module.
