ABSTRACT:
A stackable modular shelf apparatus including at least two vertically stackable frame modules and a multi-sided intermediate shelf, in which each frame module includes a plurality of generally rectangular individual frames corresponding to the number of sides on the intermediate shelf and arranged in upright planes along the sides of the shelf with the upright end members on adjacent ends of the frames juxtaposed adjacent the corners of the shelf and connected together by a plurality of connectors. One frame module is stacked on top of the other frame module and the shelf has a generally horizontal peripheral portion interposed between adjacent side members on the frames of the upper and lower frame modules. A plurality of second connectors are provided for interconnecting the upper and lower frame modules to each other and to the intermediate shelf and the second connectors each comprise a unitary resilient clip member having a U-shaped intermediate portion opening inwardly of the shelving apparatus to receive the peripheral portion of the shelf and semi-circular end portions opening outwardly of the shelf apparatus and dimensioned to receive the adjacent side horizontal members on the frames of the upper and lower frame modules.
