US 6,314,955 B1 · Collapsible barbeque and cooking stove

Abstract

A collapsible cooking stove including a lower housing, an upper housing, a fire chamber assembly, and at least one lef mechanism. The upper housing and fire chamber assembly are interconnected by a pair of mating flanges disposed on the upper housing and fire chamber assembly. The fire chamber assemblyis interconnected with the lower housing by at least one retaining clasp associated with the fire chamber assembly that interfaces with a retaining surface located on the lower housing. The upper housing and lower housing are further interconnected by the at least one collapsing leg mechanism, which has a leg rotationally affixed to the upper housing and a linkage member rotationally affixed to both the leg and the lower housing. The collapsible cooking stove can be uncollapsed for cooking by lifting upwards on the upper housing, preferably using a bail attached to the upper housing. The collapsible stove is useful for many types of cooking and is adaptable for use with a number of utensils including a cooking plate, a grill, a wok, a Dutch oven, and a rotisserie. After use, the collapsible cooking stove can be collapsed for storage by lifting upwards on the lower housing, preferably at the bottom edge. In the collapsed condition, the collapsible cooking stove is characterized by minimal volume and low aspect ratio.

Dependent claims

A collapsible cooking stove comprising:

an upper housing;
a fire chamber assembly slidably disposed within said upper housing;
a plurality of collapsing leg mechanisms rotatably coupled to said upper housing;
and
a lower housing pivotally coupled to said plurality of collapsing leg mechanisms and slidably disposed around said upper housing, wherein moving said upper housing away from and out of said lower housing along a common axis unfolds said collapsing leg mechanisms for placement on a surface, thereby collapsing said cooking stove, and wherein moving said lower housing toward and into said upper housing along said common axis folds said collapsing leg mechanisms and collapses said cooking stove for storage.

A collapsible cooking stove comprising:

a lower housing including a base plate and a lower housing wall extending around a perimeter of said base plate forming a top opening, and including at least one retaining surface disposed on said base plate;
an upper housing slidably disposed within said top opening of said lower housing, said upper housing including at least one inner wall forming a top opening and a bottom opening, and further including an inward-facing flange disposed about a perimeter of said bottom opening of said at least one inner wall;
a fire chamber assembly for combustion of a solid fuel slidably disposed within said upper housing and said lower housing, said fire chamber assembly including an outward-facing flange capable of abutting said at least one retaining surface;
and
at least three collapsing leg mechanisms, each including a leg member rotatably affixed to said upper housing, and further including a rigid linkage member with one end thereof rotationally affixed to said leg member and an opposing end thereof rotationally affixed to said lower housing, wherein motion of said lower housing relative to said upper housing effects rotation of said leg member and said linkage member.
