Abstract
A modular unit of a shelf assembly has four vertical corner posts, three pairs of longitudinal shelf-supporting cross beams fastened to the corner posts at respectively spaced elevations, and one shelf member supported by each pair of beams. Whereby this forms a first embodiment of a modular shelf assembly. Lateral modular expansion of the first embodiment into a second embodiment is accomplished by combining of a pair of such first embodiments side-by-side to each other. Depth-wise expansion of the second embodiment into a third embodiment is accomplished by combining of a pair of such second embodiments in a front to back file relative to each other. Stacking-wise expansion of the third embodiment into a fourth embodiment is accomplished by stacking a pair of such third embodiments on top of another, and so on.
