Abstract: A barbecue grill includes a body defining a heating chamber and having an open top. A main food supporting grill is mounted on the body in a generally horizontal manner so as to span at least a portion of the open top. Walls extend generally upwardly from portions of the body. The walls include opposing side walls and a rear wall extending between the side walls. A grate is mounted between the side walls and is in spaced relation to the rear wall so as to define a generally vertically arranged fire chamber for holding a source of heat generating fuel. A secondary food supporting grill is mounted between the side walls, forwardly of the grate and above and generally parallel to the main grill.

Abstract: A removable firebox for use in a portable, collapsible barbecue grill including retractable heating grate on top of the firebox and a retractable mid-level cooking grill for providing high-temperature cooking. A lower main grill is disposed in a base cavity of the barbecue grill for providing moderate temperature cooking. The firebox rests in the base cavity of the grill housing and provides heat to a cooking area defined by the base cavity, an upper lid of the housing and a pair of side walls extending upward from the base cavity. The firebox and/or the upper lid includes insulation and/or cooling baffles to protect users from heated surfaces. Venting is provided from the sides and rear of the grill housing. When collapsed, the grate and grills fold onto or are retracted within the firebox, and the entire firebox assembly is stowed in a sealed grill housing. The top and bottom portions of the grill housing mate to form a sealed container-like structure for convenient transportability or storage.
