Abstract
The invention comprises a portable open flame fireplace. The invention has a planar base with a plurality of gas orifices. The base is of any desired shape. The gas is directed through channels in the base to the orifices, where it emerges and ignites. In an alternate embodiment, the base is enclosed with a watertight windscreen above the base. The windscreen may also contain water, which allows the illusion of flames emerging from a free water surface. The invention further comprises a detachable portable fuel source, such as a propane gas bottle. The invention also has a removable cover for storage and transport.
Claims15
A portable fireplace comprising:
- a fuel source;
- a fuel pipe connected to said fuel source and having a plurality of orifices facing vertically with a minimal spacing of one inch;
- said fuel pipe mounted in a stand suitable to place on the ground;
- a windscreen mounted to the stand, wherein the windscreen protects flames issuing from said orifices from being extinguished due to high air flow over said orifices, and the flames provide a visual effect of a fireplace;
- and
- a combination cover and stand having a planar surface and having first and second opposing sides connected to said planar surface at opposing edges and normal to said planar surface sized to cover said portable fireplace when not in use, and support said portable fireplace when in use.

A portable fireplace comprising:
- a base having a first surface and having a plurality of orifices in said first surface, each of said orifices connected by a gas channel extending through said base to a connecting block;
- a fuel gas port connected to said connecting block;
- a windscreen having a plurality of surfaces normal to said base;
- said plurality of surfaces encircling said first surface;
- a spacing between said orifices ranging from 1″ to 2 feet;
- a watertight seal between said windscreen and said first surface;
- a noncombustible fluid contained within said windscreen over said first surface, whereby a gas flows from said orifices through said fluid to burn above a surface of said fluid;
- wherein each of said orifices further comprises:
- a pipe having a length substantially equal to a height of a fluid surface above said first surface;
- said pipe having an orientation substantially normal to said first surface;
- wherein said base comprises a non-combustible material;
- a plurality of legs attached to a bottom surface of said planar base;
- said bottom surface opposite to said first surface;
- a cover having a planar surface and having first and second opposing sides connected to said planar surface at opposing edges and normal to said planar surface;
