ABSTRACT:
A nearly all-plastic food cover is described. It includes a pair of upright side panels resting upon a substantially horizontal base such a table or the like, and a pair of mirror image front and back L-shaped panels.
The side panels each has a pair of oppositely canted, stops molded in its side wall. Each stop is equi-spaced about a working plane normal to both side panels and the horizontal base.
Each L-shaped panel includes an upright, wall segment that rests upon the horizontal base in the closed position of the food cover, and a roof segment that is canted in mirror image fashion about a plastic spider hinge coincident with the working plane. The canted roof segments are designed to be supported upon the canted stops of the side panels in both the full closed and half-open positions of the food cover.
The spider hinge also includes a central spine segment coincident with the pivot axis and a plurality of arms and legs radiating from the spine segment, two of which attach to the lips of the L-shaped panel by means of a series of hand tightened wing nut-bolt combinations. Thus, the invention can be easily assembled and disassembled at an off-site location without tools.
