Abstract: A portable grill having a rectangular structural foam base and a structural foam pillar defining the outside of the grill. A metal collar is mounted on the pillar with a ceramic insulating gasket and a metal heat shield in contact with the gasket and collar. Aluminum bottom and top shells enclose the burner. At least one shelf bracket is on the bottom shell with a structural foam side table mounted thereon. The preferred foamed polymer has a flexural modulus of over 150,000 psi and a hardness of over 80 Rockwell Hardness R. The pillar and base have ribs aligned to resist bending or flexing. The preferred gasket is formed from ceramic material capable of resisting a temperature of at least 1800° F. during continuous use. The grill can operate at full combustion for at least eight hours for at least six consecutive days.

Abstract: A portable cooking grill includes a substantially hollow pillar made from structural foam polymer mounted to a base. The top end of the pillar is coupled to a bottom shell where combustion takes place to cook food. A thermal insulator is disposed between the bottom shell and the top end of the pillar to protect the pillar from damage caused by heat generated by the combustion in the bottom shell. The structural foam pillar makes the grill light, easy to clean and maintain, and less costly to produce. The result is a grill that is very attractive and very durable, yet affordable.
