Abstract: An adjustable height table includes a pair of spaced upright support members each having an upper free end and a lower end, with the lower ends each connected to a pair of leg members. A work surface is disposed between the support members. A pair of forwardly extending brackets and a pair of rearwardly extending brackets are each adjustable mounted to the support members and the work surface is connected to the brackets by manually operable latches. The work surface is thereby height adjustable by adjusting the positions of the brackets on the support members and the entire assembly may be packaged and shipped in essentially flat form and easily assembled without tools at its shipped destination.

Abstract: A system for interlocking together two panel members comprises a washer member having a first washer portion connected by a first necked down portion to a second intermediate washer portion and a third washer portion connected by a second necked down portion to the second intermediate washer portion. A bore runs through the washer member for receiving a screw for fastening the washer member to a side of a first panel member. A second panel member has a keyhole slot and an aperture spaced from the keyhole slot. A resilient clip member has one end formed with a right angle projecting portion and a second end formed with an aperture configured to securely receive the first necked down portion of the washer member.

Abstract: A panel system includes a rigid generally rectangular frame assembly formed from a pair of spaced upright members and a plurality of transverse members connecting the upright members. One of the transverse members is positioned intermediate the ends of the upright members and has a generally H-shaped configuration in cross-section. A generally elongate channel fits within the intermediate transverse member and has an upwardly projecting portion which is narrower in width than the transverse member. The projecting portion serves to provide for the mounting of electrical devices and also creates a light stop when decorative tiles are used to form a gap or slot in the frame assembly for passage of electrical cables and wiring into the interior of the frame assembly.
