Abstract

The device of the present invention can be used as a cooking unit, or as a table, or as a suspended support. When the device is used as a cooking unit, a stand thereof supports a pan at the upper end of the stand. A larger, lower end of a hollow, truncated pyramidal support member is disposed on the pan. The smaller, upper end of the support member receives the smaller, lower end of a hollow, truncated pyramidal firebox. A fire grate is supported within the firebox intermediate its smaller, lower end and its larger, upper end. A cooking grill is also supported within the firebox above the fire grate, adjacent the larger, upper end of the firebox. To convert the cooking unit into a table, the pan, support member, firebox, fire grate, and cooking grill are removed from the stand. Then, the cooking grill and fire grate are successively disposed on the stand at the location previously occupied by the pan. The support member and firebox, which have hinged walls, are then individually folded into substantially flat configuration and are disposed above the fire grate and the cooking grill. The pan is disposed above the folded support member and the folded firebox and on top of the stand as a cover and is the table top surface for the table.
