Abstract
An upright shelf unit with cantilevered shelves for mounting to the carriage of a mobile storage system. The shelf unit is assembled from a pair of end uprights mounted to the carriage and spaced apart from each other, and at least one interior upright mounted to the carriage between the end uprights, to form pairs of adjacent uprights. Each of the uprights has slots formed therein to accommodate a plurality of shelves. Each shelf has hooks at each end for engaging with the slots of an upright at each end. The interior upright is constructed of a pair of channels facing together. Welded between the two channels is a trapezoidal gusset and above that a rectangular reinforcing member, both having the same thickness. The top end of the gusset and the bottom end of the reinforcing member butt together about halfway up the upright. The width of the reinforcing member and the top end of the gusset are approximately the width of the channels, the thickness being the same. The width of the gusset increases gradually toward the bottom end of the gusset until it is substantially wider than the channels. Together, in the butting relationship just described, the gusset and reinforcing member extend over the entire length of the channels.
