Abstract

A portable gas stove includes a rectangular housing defined by parallel front and rear panels joined to parallel, opposed side panels. A top opening at an upper end of the housing provides access to at least one burner, and a hinged cover is adapted to pivot to close the upper opening entirely. At the bottom end of the housing, a coffer is formed with a downward opening, and a pair of flanges extending inwardly at the side edges of the coffer are dimensioned to retain the disassembled stove legs disposed therebetween. A clamp is provided to secure the legs in the coffer for travel with the stove. Each leg includes a tubular main portion, and a top end having an L-section. The L-section is dimensioned to fit in complementary fashion over any corner vertex formed by the conjunction of a side and front or rear panel of the housing. Each corner vertex includes a slot extending vertically therein, and a nut is slidably supported by a nut holder for translation along the slot. A mounting screw extends through the apex of the L-section to engage the nut within the slot, whereby the upper end of each leg may be secured to a corner of the housing. Translation of each nut in its respective slot is possible when the mounting screw is engaged but not tightened in the nut, permitting vertical adjustment of each leg before the nut is tightened. Thus the stove may be leveled to obtain stable support on uneven terrain.

Claims

1. A portable stove, including:

a housing for supporting at least one burner, said housing including a plurality of corners;

a plurality of leg assemblies, each having a lower end adapted to be ground-engaging and an upper end adapted to engage one of said plurality of corners;

means for releasably securing said upper end of each leg assembly to one of said plurality of corners; and

,

means for securing and storing said plurality of leg assemblies in said housing;

said upper end of each of said leg assemblies including an angle iron portion having two panels extending from a common spine and defining an included angle therebetween; and

,

a plurality of mounting screws, each extending through said spine of one of said angle iron portions.

2. The portable stove of claim 1, wherein said included angle of said angle iron portion of any of said plurality of leg assemblies provides a complementary fit to any of said corner of said housing.

3. The portable stove of claim 1, further including a plurality of slot means, each slot means extending through a corner of said housing, a plurality of nuts, each adapted to engage one of said mounting screws, and means for slidably supporting each of said nuts within said housing for translation along one of said slot means.

4. The portable stove of claim 3, wherein said means for slidably supporting including a sliding bracket having opposed side flanges, said side flanges engaging said slot means in slidable fashion, one of said nuts secured to each of said sliding brackets.

5. The portable stove of claim 4, wherein said slot means includes a first slot extending through one of said corners of said housing.

6. The portable stove of claim 5, wherein said slot means includes a second slot formed in an interior structural member of said housing, said second slot extending substantially parallel and spaced apart from said first slot, said sliding bracket engaging opposed side edges of said second slot.

7. A portable stove, including:

a housing for supporting at least one burner, said housing including a plurality of corners;

a plurality of leg assemblies, each having a lower end adapted to be ground-engaging and an upper end adapted to engage one of said plurality of corners;

means for releasably securing said upper end of each leg assembly to one of said plurality of corners; and

,

means for securing and storing said plurality of leg assemblies in said housing;

said means for securing and storing said plurality of leg assemblies including a storage compartment formed in said housing;

said storage compartment including a length dimension along one axis that is greater than the length dimension of said leg assemblies, whereby said leg assemblies may be disposed parallel to said one axis and received within said storage compartment;

said storage compartment including an outer opening, and further including a pair of flanges disposed at said outer opening and converging along said one axis, the distance defined between said pair of flanges being less than said length dimension, whereby said flanges retain said leg assemblies within said storage compartment.

8. The portable stove of claim 7, further including clamping bracket means for securing said leg assemblies in said storage compartment.

9. The portable stove of claim 8, wherein said storage compartment includes a bottom panel on which said leg assemblies impinge, and said clamping bracket includes a blade portion, said blade portion adapted to extend in a first position parallel to said bottom panel and clamp said leg assemblies between said blade portion and said bottom panel.

10. The portable stove of claim 9, further including means for releasably securing said blade portion in said first position, whereby said clamping means may be moved to a second position in which said leg assemblies are freely removable from said storage compartment.

11. The portable stove of claim 10, wherein said means for releasably securing includes a threaded fastener extending through said bottom panel and said clamping means.

12. The portable stove of claim 11, wherein said storage compartment includes a sidewall and an opening formed in said sidewall, and said blade portion includes a tip portion adapted to be releasably retained in said opening when said blade is disposed in said first position.

13. The portable stove of claim 7, wherein said storage compartment comprises a coffer recess formed in a bottom portion of said housing.

14. The portable stove of claim 13, wherein said housing includes a bottom conformation adapted to be supported stably on a flat surface without recourse to support by said leg assemblies.

15. A portable stove, including:

a housing for supporting at least one burner therein, said housing including a plurality of corners;

a plurality of leg assemblies, each having a lower end adapted to be ground-engaging and an upper end adapted to engage one of said plurality of corners;

means for coupling said upper end of each leg assembly to one of said plurality of corners in height-adjustable fashion, including a plurality of slot means, each slot means extending through one of said corners of said housing, a plurality of fastener means, each extending from one of said upper ends of said leg assemblies and through a respective one of said slot means, and means within said housing for releasably securing said fastener means within said slot means.

16. The portable stove of claim 15, wherein said fastener means includes a plurality of screws, each extending from one of said upper ends of said leg assemblies, and said means for releasably securing includes a plurality of nuts adapted to receive said screws, and means for securing said nuts in slidable fashion in said second slots, whereby each of said screws may extend through a respective first slot to engage a respective nut in a respective second slot.

17. The portable stove of claim 16, wherein tightening each of each of said screws in its respective nut also immobilizes the respective means for securing the nut in slidable fashion in the second slot.
