Central Hub Assembly 30 - The
Central hub assembly 30 includes: -
- Central
core tube section 32 - Support assembly mount sections (4) 34
- Longer connector sleeve (1) 36
- Shorter connector sleeve (1) 37
- Pivot sleeves (4) 38
- Central
- The
central hub assembly 30 is configured to provide a connection between the three wing support assemblies 20 and thegas line member 40. The connection between thecentral hub assembly 30 and two of the three wing support assemblies 20 is a pivoting connection. These two assemblies are designated 20P in for exampleFIGS. 15 and 16 . However the third wing support assembly (designated 20F in for exampleFIGS. 15 and 16 ) is fixed relative to thecentral hub assembly 30, and also has thegas line member 40 fixed thereto by welding or the like. This is advantageous in that it provides additional stability when open or closed, and the folding/breakdown process is simple and does not tend to bind. - The rigid fixation of
wing support assembly 20F relative to thecentral hub assembly 30 is provided by aconnector sleeve 36 which is elongate and tubular, and accepts the tubular ends of thewing support assembly 20F, such its tubular main loop is complete. Thisconnector sleeve 36 is welded (or otherwise fixed) relative to the tubular ends of the wing support assembly 20 as well as welded (or otherwise fixed) relative to the centralcore tube section 32, such that the longitudinal axes of theconnector sleeve 36 and the centralcore tube section 32 are substantially parallel. - The pivoting connection of the two
wing support assemblies 20F relative to thecentral hub assembly 30 is substantially similar, and thus one will be discussed as an example of the other. A pair ofpivot sleeves 38 is used to provide a pivoting connection between each of thewing support assemblies 20F and thecentral hub assembly 30. Each pair ofpivot sleeves 38 is welded to the circumferential surface of thecentral hub assembly 30 each pair shares a common tubular axis. Ashorter connector sleeve 37 is also used for each of thewing support assemblies 20P such that theshorter connector sleeve 37 accepts the ends of the accepts the tubular ends of the correspondingwing support assembly 20P, such its tubular main loop is complete. Theconnector sleeve 36 is attached to the tubular ends of the correspondingwing support assembly 20P by set screws, welding, or the like. - Once assembled, the
shorter connector sleeve 37 is effectively captured between twocorresponding pivot sleeves 38 as shown inFIG. 15 , such that thewing support assembly 20P can pivot relative to thecentral hub assembly 30 about a pivoting axis which is preferably common to the bore axis of theshorter connector sleeve 37 and thepivot sleeves 38. This allows theoutdoor stove 10 to be manipulated from its erected position inFIG. 1 , for example, to its collapsed configuration ofFIG. 5 , 6 or 15. - Rigid
Gas Line Assembly 40 - The rigid
gas line assembly 40 includes the following: -
- 41 body
- 42 Brass Fitting
- 43 Downstream Tip
- 44 Bend
- The
body 41 is rigid, elongate and tubular, and passes gas from the brass fitting at it inlet to the downstream tip at its exit. Just before the exit there is a bend 44 (seeFIG. 16 for example), such that its opening is preferably proximate the center of the lower opening of the central core tube section, such that the downstream-most tip of the gas line member can direct gas into the lower opening of the central core tube section. - The rigid gas line assembly is welded to the
wing support assembly 20F at two weld locations W (seeFIG. 15 for example). - Flexible
Gas Line Assembly 50 - The Flexible
gas line assembly 50 includes the following: -
- 51 body
- 52 upstream fitting
- 53 downstream fitting
- The body 51 is flexible, elongate and tubular, and passes gas from the upstream fitting 52 at its inlet to the
downstream fitting 53 at its exit. Thedownstream fitting 53 of the flexiblegas line assembly 50 is configured to mate with theupstream fitting 42 of the rigidgas line assembly 40. - The upstream fitting 52 of the flexible
gas line assembly 50 is configured to mate with a propane or other gas storage device such as a one pound propane cylinder or twenty pound propane tank. - Materials
- It may be understood that conventional steel or iron may be used instead of stainless steel. The flexible body 51 of the flexible
gas line assembly 50 - Erection and Breakdown
- Erection and breakdown of the
outdoor stove 10 is very simple. - To erect the
outdoor stove 10 from configuration ofFIG. 5 , 6 or 15, the three wing support assemblies 20 are pivoted from the relative positions of shown inFIG. 5 , 6 or 15 to that ofFIG. 1 , and theoutdoor stove 10 is placed on a preferably flat supporting surface 100 such as the ground, a deck, or the like. - To break down the
outdoor stove 10, all cooking elements such as pots or the like are removed from the top of theoutdoor stove 10, and the device is allowed to properly cool. The three wing support assemblies 20 are then pivoted from the relative positions of shown inFIG. 1 toFIG. 5 , 6 or 15. - Therefore it may be seen that the outdoor stove (a.k.a. “outdoor cooker”) 10 according to the present invention is configured to be easily set up and taken down, has a minimum of parts, yet provides a secure cooking surface.
- Many modifications and other embodiments of the inventions set forth herein will come to mind to one skilled in the art to which these inventions pertain having the benefit of the teachings presented in the foregoing descriptions and the associated drawings. Therefore, it is to be understood that the inventions are not to be limited to the specific embodiments disclosed and that modifications and other embodiments are intended to be included within the scope of the appended claims. Although specific terms are employed herein, they are used in a generic and descriptive sense only and not for purposes of limitation.
