1. Field of the Invention
The present invention relates to portable stoves that are adapted to backpacking activities. More particularly, the present invention relates to an improved stove with nested pot arrangement wherein a specially configured frame has flanged side portions that form legs and wherein recesses accept a portion of the wall of the pot, a burner element being supported upon the frame, the burner element being nested within the confines of the pot when in a storage position.
2. General Background of the Invention
Backpacking stoves are known that occupy very little space. However, most of these stoves generate a small amount of heat so that they are restricted to light cooking activity such as boiling water, frying eggs, frying bacon, or like food items. A need exists for a more robust yet portable stove arrangement that can cook larger quantities of food in a relatively large pot having a diameter that approaches the length and/or width of the stove and which can accept optional accessories such as an oven cabinet or smoker cabinet.
Many stoves are powered with commercially available containers of gaseous fuel. Such stoves are typically very large and too bulky to be used for backpacking purposes. Such stoves typically are not adapted to form a nested arrangement with a very large pot wherein the diameter of the pot approaches or is larger than one of the length or width dimensions of the stove frame.
The present invention provides an improved portable stove and pot apparatus. The apparatus features a frame that has upper and lower surfaces, the frame including a pair of spaced apart channel members connected by a central plate section.
Each channel member includes a horizontally extending web, a long flange and a short flange.
Each short flange provides a connection between a web and the central plate section.
A pair of opposed recesses are provided on the lower surface of the frame, each recess being defined by the web and flanges of the channels.
A pot is provided that nests with the frame. The pot provides a sidewall and a bottom. The sidewall has a pot rim spaced away from the bottom that fits the recesses, wherein the rim engages the web and the sidewall occupies a position in between the flanges of each channel member. The pot sidewall has a height that is preferably slightly larger than the length of the longer flange.
The pot and burner apparatus can provide one or more removable grate members that attach to the frame upper surface.
The grate member or members can each connect to the frame at diagonally opposing corners of the frame.
The apparatus of the present invention is adapted to accept optional cabinets such as a smoker cabinet or oven cabinet that fits the upper surface of the frame.
Each of the grate members can provide a retainer that restrains the pot from substantial lateral movement when the pot is in a cooking position upon the grate members and above the burner element.
The smoker cabinet has upper and lower end portions, a front door that enables access to a majority of the front area of the cabinet and a side door near the lower end of the cabinet.
The cabinet can provide opposed slides at the lower end portion of the cabinet that are receptive of one or more trays such as a wood chips tray and/or a water containing tray.
For a further understanding of the nature, objects, and advantages of the present invention, reference should be had to the following detailed description, read in conjunction with the following drawings, wherein like reference numerals denote like elements and wherein:
Frame 11 has upper surface area 15 and lower surface area 16. Burner element 17 is mounted to plate 14 at upper surface area 15. A gaseous fuel inlet fitting 18 is provided on burner element 17 for enabling a connection to be made between an available gas containing cylinder or fuel canister and burner element 17. Such cylinders are known and are commercially available, sold under the Coleman® mark, for example.
Each channel member 12, 13 includes a long flange 19, short flange 20 and web 21. The long flange 19 has a foot (see
A concavity 35 is defined by the central plate 14 and the short flanges 20 of the spaced apart channel members 12, 13. Concavity 35 is provided for holding burner element 17. The burner element 17 is preferably a gaseous fuel fired burner element that is mounted to the upper surface area 15 of the central plate section 14, within the concavity.
Front wall 46 has an aperture 47 for receiving gas inlet fitting 18 of burner element 17. Front wall 46 has ventilation openings 48. Rear wall 49 extends upwardly from central plate 14 and connects to short flanges 20 of channel members 12, 13. Rear wall 49 has ventilation openings 50.
The frame 11 provides a plurality of corners 27. In the preferred embodiment, each corner 27 can be provided with an aperture 28 that is receptive of a grate member 29, 30 (see
Each grate member 29, 30 preferably has a projection 31, 32 at its opposing end portions as shown. These projections 31, 32 fit the apertures 28 of diagonally opposed corners 27 (see arrows 45,
Pot 40 and burner frame 11 nest together for storage such as when occupying the interior of a user's backpack.
Burner frame 11 optionally accepts a cabinet (e.g. smoker or oven) 60 which can be placed upon the webs 21 of channel members 12, 13 as indicated schematically by arrow 54 in
As shown in
Rear wall 55 provides opposed flanges 62, 63 that are provided with apertures for enabling the side walls 57, 58 to be bolted to the rear wall 55 at the flanges 62, 63. A bolted connection 64 can employ wing nuts 65 for speed. Side walls 57, 58 are provided with a plurality of openings that enable a bolted connection to be formed with rear wall 55. Apertures are also provided in side walls 57, 58 for enabling a bolted connection to be made with bracket 66.
Bracket 66 provides flanges 67, 68 that are connectable to side panels 57, 58 using bolted connections 64 for example. Each side panel has a plurality of shelf holders 69 that enable one or more shelves 70 to be supported at intervals (see
To retain front wall 56 in the operating, cooking position of FIGS. 12 and 14-15, lid 72 is placed over the combination of rear wall 56, side walls 57, 58 and front wall 56 as shown in
Lower shelf holders 75 can be provided for supporting one or more pans 76, such as a water pan or wood chips pan. Side walls 57, 58 can optionally be provided with vents 77. Side walls 57, 58 are preferably provided with handles 78 that enable a user to place smoker or cabinet 60 upon frame 11 or to remove it.
Rear wall 55 can be provided with an access panel 79 that moves between open and closed positions by rotating upon hinge 80. Access panel 79 can be provided with handle 81. A thermometer 61 can be placed on front panel 56.
