Unitized modular rack for vertical storage of flat sheet materials

Claim 1

A unitized module adapted for interconnection with one or more other such modules to form a modular rack for storage materials comprising, in combination, a base member having a leading end and a trailing end each of said leading and trailing ends being provided with connecting means for interconnecting adjacent base members, said base member formed by at least one base rail, said base rail having a forward support bar mounted thereon and spaced rearwardly from said leading end of said base member and extending upwardly therefrom, said base rail further including a rear support bar mounted thereon and extending upwardly therefrom, said rear support bar overhanging the trailing end of said base member thereby to form a connecting offset, said forward and rear support bars interconnected by a top frame member, said leading end of one module cooperating with the connecting offset trailing end of a next adjacent module such that the point of interconnection between adjacent modules is removed from contact with the materials stored in said rack, whereby interconnection of one unitized module with an adjacent module is accomplished by inserting the leading end of said base member of one module into the connecting offset trailing end of the next adjacent module such that said rear support bar overrides the leading edge of adjacent base members thereby to conceal the point of interconnection between adjacent unitized modules from the materials stored within said rack.
