Abstract: An improved undershelf elongated task light fixture. The fixture includes an elongated housing means having a top, a front wall depending from the top, and a back wall depending from the top and spaced rearwardly of the front wall. A tubular lamp is positioned in the housing between the front wall and the back wall. An elongated shield having a rearwardly facing, downwardly and rearwardly inclined reflector element is mounted on the housing. The shield lies beneath, and extends forwardly of, the tubular lamp. The housing and shield define an elongated opening adjacent the base of the housing between the front wall and the tubular lamp. A light diffuser, such as a batwing diffuser, covers the opening. The elongated shield substantially blocks direct radiation from the tubular lamp from impinging on the light diffuser, hence prevents veiling reflections almost entirely.

Abstract: An illumination system usable in a display cabinet includes a plurality of spaced apart, low-voltage lamps. The lamps are supported by a reflector off-set from a shell or housing. The air space created between the reflector and the shell or housing provides thermal insulation such that the system will not excessively heat the display cabinet.

Abstract: A movable storage system having a plurality of storage units disposed side-by-side and movable relative to each other to selectively open access paths between selected pairs of units. In response to operation of enabling and selection switches, a new aisle is identified, and the necessary units are moved to open the new aisle in a determined time sequence.

Abstract: A shelf assembly which is assembleable without extraneous fasteners and which may be shipped flat and ready for attachment to a pair of spaced standards. The assembly comprises an expansive shelf of formed sheet metal having an upper shelf surface portion and a lower portion which provides groups of spaced slots opening into hollows within the shelf. Shelf support brackets, each having an expansive main body portion, hooks for supporting the assembly on a standard and a pair of mounting ears integral with the bracket extend laterally from the upper regions of the bracket main body portion. The mounting ears are seated within the hollows of a corresponding group of slots. The ears on each bracket have projections by which the shelf and bracket are interconnected. At least one projection is a protuberance, the combined width of the ear and the protuberance being greater than the width of the slot portion through which that ear entered. One ear has a hook-like projection.
