Abstract
Abstract A compact, lightweight, collapsible, outdoor cooking apparatus, which can be used as a reflector oven for baking foods by an open fire, hot coals, or other source of heat, and can also be used for grilling, frying and boiling, comprises a partially demountable, open framework adapted to have aluminum foil or the like applied thereto. The framework is made up of an elongate tubular member extending longitudinally and two corresponding sets of three transversely extending radial members adapted for removable attachment, respectively, to opposite ends of the tubular member. The outer members of one set are pivotally interconnected to the corresponding outer members of the other set by means of longitudinal connecting members, and the intermediate members of each set serve as struts with their free ends being pivotally interconnected to the ends of the outer members of the set by elongate connection means. The apparatus is used as a reflector oven by stretching aluminum foil or the like from attachment to one of the longitudinal connecting members, around the elongate tubular member to attachment to the other longitudinal connecting member, thereby providing reflective surfaces that diverge outwardly from the tubular member and, when faced toward a source of heat, concentrate baking or broiling heat in the area between such surfaces. A grill is advantageously provided for suspension between the struts to support food to be baked or broiled. The apparatus may be used as a stove for frying or boiling by stretching aluminum foil or the like directly between the longitudinal connecting members thereby providing a cooking surface for horizontal positioning over a campfire or other heat source.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
246 words
Collapsible, outdoor cooking apparatus, which can be used as a reflector oven for baking food and can also be used for grilling, frying and boiling, comprising an elongate, tubular member; two sets of three transversely extending radial members adapted for removable attachment, respectively, to opposite ends of the tubular member with the members of one set of radial members being parallel with the corresponding members of the other set of radial members; longitudinal rods connecting respectively, the free end portions of the outer members of one set of radial members to the outer members of the other set of radial members; and support members which connect the end portions of the outer members of each set of radial members to the end portion of the intermediate member of that set, said apparatus being used as a reflector oven by stretching a flexible, reflective material from one longitudinal rod, around the elongate tubular member, to attachment to the other longitudinal rod thereby providing reflective surfaces that diverge outwardly from the tubular member and, when faced towards a source of heat, concentrate baking or broiling heat in the area between said surfaces, and suspending a grill between the intermediate members to support food to be baked, and said apparatus being used as a stove for grilling, frying or boiling foods by suspending a grill or stretching a flexible material directly between the longitudinal rods as a cooking surface for horizontal positioning over a campfire or other heat source.
Claim 2
Dependent Claim
246 words
Collapsible, outdoor cooking apparatus, which can be used as a reflector oven for baking food and can also be used for grilling, frying and boiling, comprising an elongate, tubular member; two sets of three transversely extending radial members adapted for removable attachment, respectively, to opposite ends of the tubular member with the members of one set of radial members being parallel with the corresponding members of the other set of radial members; longitudinal rods connecting respectively, the free end portions of the outer members of one set of radial members to the outer members of the other set of radial members; and support members which connect the end portions of the outer members of each set of radial members to the end portion of the intermediate member of that set, said apparatus being used as a reflector oven by stretching a flexible, reflective material from one longitudinal rod, around the elongate tubular member, to attachment to the other longitudinal rod thereby providing reflective surfaces that diverge outwardly from the tubular member and, when faced towards a source of heat, concentrate baking or broiling heat in the area between said surfaces, and suspending a grill between the intermediate members to support food to be baked, and said apparatus being used as a stove for grilling, frying or boiling foods by suspending a grill or stretching a flexible material directly between the longitudinal rods as a cooking surface for horizontal positioning over a campfire or other heat source.
Claim 3
Dependent Claim
67 words
Collapsible outdoor cooking apparatus as claimed in claim 1, wherein said longitudinal rods are pivotally attached to the radial members, whereby when the radial members are removed from the tubular member, they remain interconnected to the longitudinal rods and support members and can be folded together with the longitudinal rods and support members into a compact, elongate bundle which can be inserted coaxially within the tubular member.
Claim 4
Dependent Claim
182 words
Collapsible outdoor cooking aPparatus as claimed in claim 2, wherein the end portions of the outer radial members which are to be attached to the respective ends of the tubular member are pivotally attached together by a grommet and the ends of the tubular member have slots opening longitudinally thereinto in which the outer radial members are positioned so that the grommet is adjacent to the inside wall of the tubular member, the tubular member having a small hole on each end thereof, with the small hole being in line with the opening in said grommets, the tubular member also having a square hole on each end thereof directly opposite the small holes, each intermediate radial member having a short end portion of round cross-section with the remainder thereof having a square cross-section slightly smaller than the square holes in the tubular member so that the intermediate radial members can slide through the square holes with the short portion thereof extending through said grommets and through the small hole in the tubular member to pinion the radial members to the tubular member.
Claim 5
Dependent Claim
46 words
Collapsible outdoor cooking apparatus as claimed in claim 3 wherein each intermediate radial member has a circumferential groove therein which engages the square hole in the tubular member so that said intermediate radial member can be rotated to lock itself in engagement with the tubular member.
Claim 6
Dependent Claim
55 words
A collapsible outdoor cooking apparatus as claimed in claim 2 wherein aluminum foil is stretched from attachment to one of the longitudinal rods around the elongate tubular member to attachment to the other longitudinal rod thereby providing divergent reflective surfaces, and a grill is suspended between the intermediate members for supporting food to be baked.
Claim 7
Dependent Claim
73 words
Collapsible outdoor cooking apparatus as claimed in claim 5 wherein the grill comprises a plurality of elongate, parallel elements connected together at their respective ends by pivoted connecting members which allow the grill to be flexed in one direction but not in its complementary direction whereby the grill can be suspended between the intermediate members as a rigid, flat grill and can also be rolled up into a compact roll for storage purposes.
Claim 8
Dependent Claim
44 words
Collapsible outdoor cooking apparatus as claimed in claim 2 wherein aluminum foil is stretched directly from attachment to one of the longitudinal rods to attachment to the other longitudinal rod as a cooking surface or positioned horizontally over a fire or other heat source.
Claim 9
Dependent Claim
28 words
Collapsible outdoor cooking apparatus as claimed in claim 2 wherein a grill is suspended between the longitudinal rods and positioned horizontally over a fire or other heat source.
Claim 10
Dependent Claim
72 words
Collapsible outdoor cooking apparatus as claimed in claim 8 wherein the grill comprises a plurality of elongate, parallel elements connected together at their respective ends by pivoted connecting members which allow the grill to be flexed in one direction but not in its complementary direction, whereby the grill can be suspended between the intermediate members a rigid, flat grill and can also be rolled up into a compact roll for storage purposes.
