Abstract

Abstract A portable campfire grill employing three identical elongate members constructed of steel or like heat resistant material. Each of the elongate members has a pair of slots, one slot being formed adjacent each end and the respective slots being oriented in opposite directions. The slots have a depth half the width of the member so that when the elongate members are engaged by interengagement at the slots, the opposite surfaces of the elongate members are in coplanar relation thereby forming a triangular shaped grill structure having a flat surface. The slots have a dimension in a direction longitudinally of the members such that the members must be stressed to effect such interengagement so that the triangular structure formed by assembling the three members is retained in assembled, operative condition.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 222 words
A portable campfire grill for supporting cooking pots on an open fire comprising a trinity of substantially identical straight linear elongate members constructed of substantially rigid heat resistant resilient material having an elastic limit, each said elongate member having a substantially uniform cross sectional shape throughout its length and a thickness dimension, two spaced apart portions of each said elongate member defining first and second oppositely opening slots extending substantially perpendicularly of the longitudinal axis of said member, each said slot having a dimension longitudinally of the respective elongate member greater than the thickness dimension and less than √3 times the thickness dimension so as to stress within the elastic limit the elongate members when assembled into a triangular configuration by interengaging the slots of respective said members, said slots having a depth approximately equal to 1/2 said width dimension so that when said members are interengaged with one another the exterior surfaces thereof are substantially coplanar, said first slot in each said member being spaced farther from the adjacent end than said second slot so that each said member has a relatively long leg portion outward of said first slot, so that with said first slot in an upward position said grill can be supported at three triangularly spaced locations which are outwardly remote from the apices of said triangular configuration.
