ABSTRACT:
A two-component shelf-like or tray assembly of two end-joined interlocking panels each fabricated of molded plastics compositions. Abutting, inter-joinable end walls of the panels are of reciprocal structural configurations, making it possible to use a single mold in fabricating the panels themselves. The panels are pivotally interengageable and manually manipulable to lock and to assume a continuous, lineally extended, expanse constituting a stable, composite, unitary structure having a generally flat or planar support surface. Integrally formed auxiliary structures permit arrangement of a plurality of panel assemblies as a tiered, vertical array. Panels either of the same or of dissimilar longitudinal dimensions may be combined to provide shelves of selectable overall length. Molds with removable sections, in length and width, provide enhanced versatility, permitting one to mold various size components or to use a selectable number of sections with reciprocal interlock producing mold components to provide panels of varying sizes. Novel adapters or fixtures for use in the tiered array of shelves enable one to provide one or more shelves which are in a slanted or pitched mode or attitude.
