Abstract

A display-type shelving unit comprises stacked, factory-assembled modules, each of which comprises four vertically elongated hinges connected by horizontal connecting elements and unfoldable from an exaggerated rhomboidal condition in which the connecting members are essentially parallel to one another to a condition in which the connecting elements define a rectangle. Shelves may be dropped into frames formed by the connecting elements to hold the modules in a rectangular condition. Hinge pins project upwardly from each hinge, and a corresponding pin-receiving recess is provided at the bottom of each hinge, so that the hinge pins are used to hold the modules in vertical alignment. The hinges have trim retaining tabs which are appropriately spaced, when the shelf module is in the unfolded condition, to engage slots along the edges of vertically elongated trim strips which serve to hide the knuckles of the hinges from view. Feet are frictionally engaged in the recesses at the bottoms of the hinges of the lowermost module, and caps are engaged with the pins at the tops of the hinges of the uppermost module. These caps allow for attachment of sign panels. In the case of a module having a sloping forward-feed shelf, wire guards are provided, which are held in place by the shelf itself.
