Portable universal cooking grill
First Claim
1. Portable universal cooking grill comprising a generally rectangular bottom wall defining mutually orthogonal first and second pairs of spaced edges;
- a first pair of walls having upper and lower edges having lengths substantially equal to said first pair of edges;
a second pair of walls having upper and lower edges having lengths substantially equal to said second pair of edges;
means for movably mounting said first pair of walls along their lower edges to said first pair of edges and for movably mounting said second pair of walls along their edges to said second pair of edges to provide a knock-down enclosure formed by said bottom wall closed about its perimeter defined by said first and second pairs of edges and open at the top opposite said bottom wall in the operative condition of the grill when said first and second pairs of walls are erect and substantially normal to the plane of said bottom wall, said means for movably mounting permitting said walls to collapse to positions proximate to and substantially coplanar with said bottom wall;
retaining means for maintaining said first and second pair of walls in an erect condition during use of the grill;
a removable food supporting member positionable above said bottom wall for supporting food to be heated and including a skewer adapted for mounting proximate to the upper edges of one of said first and second pairs of walls; and
positioning means for selectively positioning and maintaining the selected position of said skewer about a longitudinal axis thereof, whereby said first and second pairs of walls can be collapsed to render the grill portable and easily storable when not in use.

Abstract
A portable cooking grill has a bottom wall and side and end walls which are hinged to the bottom wall to form an open box or enclosure which can be collapsed by moving the walls proximate to the bottom wall. One pair of walls is provided with mating, multi-stepped slots which can support a grill tray or a deep tray or skewers at different levels. Flat leaf or blade springs automatically open the grill from the collapsed condition when a locking mechanism is opened. Folding legs are mounted on the grill or a support tray can be used where the grill is formed integrally from a blank of semi-rigid material which is heat and fire resistant. The grill is universal and can readily be used with many fuels, including coal, wood, gas and electricity, and can be used to cook by broiling, baking, boiling of liquid foods (e.g. soup), frying and the like. Both solid and non-solid foods can be prepared in a simple and convenient manner at home or while traveling. The box or enclosure can be made from an inexpensive blank, made from a fire-proof material, which can be disposed of after one or a few uses.
