DETAILED DESCRIPTION OF THE INVENTION
As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention that may be embodied in various forms. The figures are not necessarily to scale, some features may be exaggerated to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present invention.
Referring now to FIGS. 1-4, the present invention provides for a cooking apparatus 1 comprising a firebowl 2, a column 3 and a base 4. The top portion of the column 3 is attached to a bottomside of the firebowl 2 and the bottom portion of the column 3 is attached to a base 4. There is a moveable charcoal grate 5 situated within the firebowl and a cooking grate 7 adapted to be situated above the charcoal grate 5 during a cooking stage. There is a moveable chimney 6 (not shown in FIG. 1). There are two actuators, 9a and 9b respectively, which are connected to and designed to move the charcoal grate 5 and the chimney 6. There are at least two handles 8 situated on an external surface of the firebowl 2.
FIGS. 2a and 2b show the chimney 6 in the usage position and the charcoal grate 5 in the charcoal igniting stage. There is a heat source 10 attached to the column and situated adjacent to the charcoal grate during the charcoal igniting stage. The heat source 10 may be a flammable gas torch. FIG. 2b shows a cross-sectional view of the cooking apparatus 1. During its charcoal igniting stage, the charcoal grate 5 is collapsed into a “basket” form for holding the charcoals 11 which are being ignited by the heat source 10. In one embodiment, at least a portion of the charcoal grate 5 is situated within an internal cavity of the chimney 6 during the charcoal igniting stage.
FIGS. 3a, 3b and 3c illustrate the transition of the chimney 6 from the usage position to the stowage position and the charcoal grate 5 from the charcoal igniting stage to the cooking stage. Once the charcoals 11 have been ignited, the actuator 9a is activated to allow the ascent of the charcoal grate 5 from the internal cavity of the column 3 to the internal cavity of the firebowl 2. The actuator 9b is also activated to allow the descent of the chimney 6 from the internal cavity of the firebowl 2 into the internal cavity of the column 3.
FIGS. 4a and 4b show the chimney 6 in its stowage position and the charcoal grate 5 with the ignited charcoals 11 in its cooking stage. During its stowage position, the chimney 6 is situated within the internal cavity of the column 3. During its cooking stage, the charcoal grate 5 is expanded to allow the exposure of the ignited charcoals 11 and situated within the internal cavity of the firebowl 2.
FIG. 5 shows another embodiment of the present invention showing the cooking system 100 with its moveable chimney 16. The cooking system 100 comprises a firebowl 12 with an aperture 21 on its bottomside, a column 13 having top and bottom portions, 13a and 13b respectively, and a base 14. The top portion 13a of the column 13 is attached to the bottomside of the firebowl 12 and the bottom portion 13b of the column 13 is attached to the base 14. The column 13 has an internal cavity (not shown) and the aperture 21 of the firebowl 12 leads to the internal cavity of the column 13. There are handles 18 which are situated on opposing sides of the external surface of the firebowl 12. There are also supports 20 for a cooking grate (not shown) situated within the firebowl 12. There is also an access door 23 with a handle 22 for accessing the internal cavity of the column 13. There are two actuators, 19a and 19b respectively, protruding from apertures on the external surface of the column 13. The actuator 19b activates the movement of the chimney 16 from the usage position to stowage position and back to the usage position. The chimney 16 moves downwardly through the aperture 21 of the firebowl 12 into the internal cavity of the column 13 for storage. The chimney 16 moves upwardly from the internal cavity of the column 13 through the aperture 21 and into the internal cavity of the firebowl 12 to achieve the usage position. At least the top portion of the chimney is situated above the topside opening of the firebowl 12 during the usage position.
FIGS. 6-10 demonstrate another embodiment of the present invention, in particular, the cooking system 30 with the moveable charcoal grate 35. The cooking system comprises a firebowl 32 with a bottomside attached to a column 33 and the column 33 is attached to a stand or base 34. The external surface of the firebowl 32 comprises handles 38. The external surface of the column 33 shows an access door 43 with its handle 42 and apertures which allow for the protrusion of at least two actuators, 39a and 39b respectively.
FIG. 6 shows the first stage of the charcoal igniting process of the present invention. A bag 41 of charcoals 11 are poured into the expanded charcoal grate 35 or charcoal grate basket. FIG. 7 shows the second stage wherein the actuator 39a is activated to allow the charcoal grate 35 begins to collapse to create the “basket” form and allow for the descent of the charcoal grate from the internal cavity of the firebowl, through the aperture of the firebowl 32 and into the internal cavity of the column 33. FIG. 8 shows how a heat source 50 is applied to the charcoal grate 35 to ignite the charcoal 11. In one embodiment, the access door 43 with its handle 42 is used to access the charcoal grate 35 and apply the heat source to ignite the charcoal 11. In this one embodiment, the heat source is paper or other flammable materials. FIG. 9 shows that once the charcoals 11 are ignited, the actuator 39a is activated to raise the charcoal grate 35 with the ignited charcoals 11 from the internal cavity of the column 33 to the internal cavity of the firebowl 32. The charcoal grate 35 goes from the “basket” form to its expanded form to expose the ignited charcoals 11. In another embodiment, the actuator 39 a may be moved side to side or up and down to distribute the ignited charcoals 11 evenly across the charcoal grate 35. FIG. 10 shows how the cooking grate 37 is situated upon the supports 60 and positioned above the ignited charcoals 11 on the charcoal grate 35.
Numerous modifications and variations of the present invention are possible in light of the above teachings. It is therefore to be understood that within the scope of the attendant claims attached hereto, this invention may be practiced otherwise than as specifically disclosed herein.
