ABSTRACT:
The specification discloses a vertical framework structure extendable in both lateral and longitudinal directions. The structure comprises a plurality of vertical columns which are tubular members having a rectangular cross-section. At least two vertical opposing faces of the column are provided with a series of pairs of vertically and horizontally aligned spaced mounting slots. The structure further includes at least one lateral bracing member adapted to support a shelf, and extending between a pair of front and rear vertical columns. Each end of said lateral bracing member is formed with a pair of mounting lugs projecting at right angles to the plane of the bracing member, arranged in vertical alignment and spaced apart vertically a distance equal to the vertical spacing of the mounting slots on the column. At least one mounting lug has a locking means at the lower portion thereof. The horizontal bracing member has at a side surface thereof one or more upwardly extending shelf support flanges. A shelving structure is formed by the above framework structure in conjunction with at least one rectangular horizontal shelf member extending longitudinally between one lateral bracing member and the next lateral bracing member thereby forming a shelf structure. The structure of the present invention is easily assembled or disassembled without any additional members and without the aid of tools other than a small mallet.
