An inner peripheral wall extends substantially perpendicularly from the base plate. The inner peripheral wall has an inner wall venting aperture extending therethrough. An outer peripheral wall is also provided.
The outer peripheral wall being configured and sized to be slidably mounted outwardly relatively to the inner peripheral wall with its lower peripheral edge abuttingly resting on the base plate. In such a position, the outer peripheral wall is in a substantially contiguous and concentric relationship relatively to the inner peripheral wall. The outer peripheral wall being rotatable about its longitudinal axis relatively to the inner peripheral wall.
The outer peripheral wall having an outer wall venting aperture extending therethrough. The cooking device also having a grid member. One of the features of the device relates to its inherent ventilating components that allow for the creation of an up draft of air through the solid combustible material. When the outer peripheral wall is rotated about its longitudinal axis, relatively to the inner peripheral wall, the inner wall venting aperture and the outer wall venting aperture are adapted to be be put approximately in register with each other to modulate the flow rate of an up draft of air flowing into the open top container through the venting apertures.

Description
~~~.~014 i Patent Application of Therese Gadbois for a Barbecue-Type Cooking Device Field of the Invention:
The present invention relates to the field of cooking devices and is particularly concemed with a barbecue-type cooking device.
Background of the Invention:
The field of cooking devices is replete with barbecue-type cooking devices presenting various configurations. Most prior art barbecue-type cooking devices have an open-top container mounted on a set of legs and adapted to contain a solid combustible material such as charcoal or the like. A grid member is typically mounted over the open top container to support the food item.
To facilitate the ignition of the combustible material, the latter is typically previously soaked in volatile chemical substances. Although efficient, these volatile chemical substances present a potential risk of explosion and sometimes adversely alter the taste of the cooked food.
~
Accordingly, some prior art structures are provided with ventilation components that are adapted to create an up draft of air through the combustible material and thus facilitate the ignition step. Furthermore, the presence of an up draft of air through the combustible material creates an intense cooking heat effective to sear meat and the like.
The presence of a means for creating an up draft of air that will, in tum, create an intense cooking heat can prove to be particularly important in situations wherein the combustible material must be used sparingly since the searing of meat or the like can be performed more efficiently.
Examples of barbecue-type structures having ventilation components are described in US
Patent 3,327,697, issued to Sigmund Berlant on June 27, 1967, and US Patent 3,159,119, issued to Frederick W. Hottenroth, et al. on December 1, 1964. The ventilation components of the prior art, although efficient, are made up of various mechanical components and are thus relatively expensive and susceptible to breakdown.
Some of the prior art barbecue-type cooking devices are provided with a lid adapted to protectively enclose the combustible container to prevent the combustible material from getting soaked by rain or otherwise affected by environmental factors when the device is not in use.
Most prior art lids are hingely connected to the cooking device thus requiring assembly during the manufacturing process.

~
Furthermore, most prior art lids are not particularly suited to sealingly enclose the combustible material container and thus cannot be used effectively as a mean for depriving the combustible material from oxygen so as to extinguish the latter. The presence of a means for efficiently stopping the combustion of the combustible material can prove to be particularly important in conditions wherein the combustible material must be used sparingly since the combustion of the combustible material can be stopped as soon as the cooking operation is finished.
A barbecue-type cooking device having a mechanically simple yet efficient means for creating an up draft of air through the combustible material and having a means for selectively and readily extinguishing the combustible material is thus highly desirable.
These features are particularly desirable in situations wherein the combustible material is an expensive and scarce resource such as in some so-called third-world countries.
Summary of the Invention:
Accordingly, it is an object of the present invention to provide an improved barbecue-type cooking device. According to an embodiment of the present invention, there is provided a cooking device adapted for use with a solid combustible material. The cooking device comprises a substantially flat base plate. The base plate defines a base plate first surface and a base plate second surface.

Referring to figure 1, there is shown a cooking device 10 in accordance with an embodiment of the present invention. It should be understood that although the cooking device is herein illustrated in one of its particular embodiments, as being substantially cylindrical in configuration, it could also be of any suitable form and appearance without departing from the scope of the present invention.
The cooking device 10 has a substantially flat and disc-shaped base plate 12.
The base 10 plate 12 defines a base first surface 14 and a base second surface 16. A
set of supporting legs 18 is rigidly fixed to the base first surface 14. Typically, a set of three supporting legs 18 are used. The supporting legs 18 are preferably angled outwardly in a direction leading away from the base first surface 14 so as to provide for a stable support.
A substantially annular shaped inner peripheral wall 20 extends substantially perpendicularly from the base second surface 16. The inner peripheral wall 20 is provided with a set of inner wall venting apertures 22 extending therethrough.
A correspondingly shaped outer peripheral wall 24 is abuttingly rested against the base second surface 16. The outer peripheral wall 24 has an outer wall upper peripheral edge 26 and an outer wall lower peripheral edge 28. The outer wall lower peripheral edge 28 is adaptcd to contact the base second surface 16. The outer peripheral wall 24 extends substantially ~
perpendicularly from the base second surface 16.
The outer peripheral wall 24 is positioned so as to be outwardly disposed and in a contiguous and concentric relationship relatively to the inner peripheral 20.
The inner peripheral wall 20, the outer peripheral wall 24 and a portion of the base plate 12 delimited by the inner peripheral wall 20 thus form an open-top cylindrical container 29.
The outer peripheral wall 24 is provided with a set of outer wall venting apertures 30 extending therethrough. The outer wall venting apertures 30 are located so as to be positionable in register with the inner wall venting apertures 22 as will be hereinafter described.
A grid member 32 having a peripheral and substantially perpendicularly depending grid member flange 34 is abuttingly rested on the outer wall upper peripheral edge 26.
A pair of outer wall handles 36 are rigidly fixed to the outer surface of the outer peripheral wall 24 in a substantially diametrically opposed relationship relatively to one another.
In the embodiment illustrated in figures 1 through 4, the outer wall handles 36 are formed by a corresponding pair of bolts that are welded to the outer peripheral wall 24.
An inner rim 38 and an outer rim 40 both extend substantially perpendicularly from the base second surface 16. The inner rim 38 and the outer rim 40 are in substantially concentrical relationship relatively to one another and to the inner peripheral wall 20.
The inner rim 38 and ~ ~152014 the outer rim 40 define a substantially ring-shaped and open-top annular channel 42 therebetwcen. The annular channel 42 is adapted to be substantially filled with a volume of substantially granular or friable material 44 such as earth, sand or the like.
A lid 46 is adapted to enclose the outer peripheral wall 24 and the grid member 32. The lid 46 has a substantially disk-shaped lid top wall 48 and a lid flange 50.
The lid flange 50 depends integrally and substantially perpendicularly from the lid top wall 48.
The lid flange 50 has a lower peripheral edge 52. The lid 46 is configured and sized so that the lower peripheral edge 52 may be embedded into the volume of granular or friable material 44. A
lid handle 54 is fixed to the outer surface of the lid top wall 48.
A pair of locking prongs 56 extends outwardly from the outer surface of the lid flange 50. The locking prongs 56 are in a substantially diametrically opposed relationship relatively to each other. A corresponding pair of locking hooks 58 extends substantially perpendicularly from the base second surface 16. The locking hooks 58 are positioned outwardly relatively to the outer rim 40. The locking hooks 58 are configured and sized so as to be adapted to releasably hook the corresponding locking prongs 56.
In use, from the configuration illustrated in figure 1, an intended user first grasps the lid handles 54 and rotates the lid 46 relatively to the base plate 12 so as to unhook the locking prongs 56 from the locking hooks 58. The intended user then removes the lid 46 by raising the latter away from the base plate 12.
Referring to figure 1, there is shown a cooking device 10 in accordance with an embodiment of the present invention. It should be understood that although the cooking device is herein illustrated in one of its particular embodiments, as being substantially cylindrical in configuration, it could also be of any suitable form and appearance without departing from the scope of the present invention.
The cooking device 10 has a substantially flat and disc-shaped base plate 12.
The base 10 plate 12 defines a base first surface 14 and a base second surface 16. A
set of supporting legs 18 is rigidly fixed to the base first surface 14. Typically, a set of three supporting legs 18 are used. The supporting legs 18 are preferably angled outwardly in a direction leading away from the base first surface 14 so as to provide for a stable support.
A substantially annular shaped inner peripheral wall 20 extends substantially perpendicularly from the base second surface 16. The inner peripheral wall 20 is provided with a set of inner wall venting apertures 22 extending therethrough.
A correspondingly shaped outer peripheral wall 24 is abuttingly rested against the base second surface 16. The outer peripheral wall 24 has an outer wall upper peripheral edge 26 and an outer wall lower peripheral edge 28. The outer wall lower peripheral edge 28 is adaptcd to contact the base second surface 16. The outer peripheral wall 24 extends substantially ~
perpendicularly from the base second surface 16.
The outer peripheral wall 24 is positioned so as to be outwardly disposed and in a contiguous and concentric relationship relatively to the inner peripheral 20.
The inner peripheral wall 20, the outer peripheral wall 24 and a portion of the base plate 12 delimited by the inner peripheral wall 20 thus form an open-top cylindrical container 29.
The outer peripheral wall 24 is provided with a set of outer wall venting apertures 30 extending therethrough. The outer wall venting apertures 30 are located so as to be positionable in register with the inner wall venting apertures 22 as will be hereinafter described.
A grid member 32 having a peripheral and substantially perpendicularly depending grid member flange 34 is abuttingly rested on the outer wall upper peripheral edge 26.
A pair of outer wall handles 36 are rigidly fixed to the outer surface of the outer peripheral wall 24 in a substantially diametrically opposed relationship relatively to one another.
In the embodiment illustrated in figures 1 through 4, the outer wall handles 36 are formed by a corresponding pair of bolts that are welded to the outer peripheral wall 24.
An inner rim 38 and an outer rim 40 both extend substantially perpendicularly from the base second surface 16. The inner rim 38 and the outer rim 40 are in substantially concentrical relationship relatively to one another and to the inner peripheral wall 20.
The inner rim 38 and ~ ~152014 the outer rim 40 define a substantially ring-shaped and open-top annular channel 42 therebetwcen. The annular channel 42 is adapted to be substantially filled with a volume of substantially granular or friable material 44 such as earth, sand or the like.
A lid 46 is adapted to enclose the outer peripheral wall 24 and the grid member 32. The lid 46 has a substantially disk-shaped lid top wall 48 and a lid flange 50.
The lid flange 50 depends integrally and substantially perpendicularly from the lid top wall 48.
The lid flange 50 has a lower peripheral edge 52. The lid 46 is configured and sized so that the lower peripheral edge 52 may be embedded into the volume of granular or friable material 44. A
lid handle 54 is fixed to the outer surface of the lid top wall 48.
A pair of locking prongs 56 extends outwardly from the outer surface of the lid flange 50. The locking prongs 56 are in a substantially diametrically opposed relationship relatively to each other. A corresponding pair of locking hooks 58 extends substantially perpendicularly from the base second surface 16. The locking hooks 58 are positioned outwardly relatively to the outer rim 40. The locking hooks 58 are configured and sized so as to be adapted to releasably hook the corresponding locking prongs 56.
In use, from the configuration illustrated in figure 1, an intended user first grasps the lid handles 54 and rotates the lid 46 relatively to the base plate 12 so as to unhook the locking prongs 56 from the locking hooks 58. The intended user then removes the lid 46 by raising the latter away from the base plate 12.
The grid member 32 is then removed by applying radial finger pressure on opposite sides of the grid member flange 34 and raising the grid member 32 upwardly.
Charcoal, wood or any other suitable solid combustible material is then introduced into the open-top cylindrical container 29. The solid combustible material is then ignited from the top surface thereof, using tinder or any other suitable means. The grid member 32 is then placed back to its original position wherein it is abuttingly sitting against the outer wall upper peripheral edge 26.
The inner Wall venting apertures 22 and the outer wall venting apertures 30 are adapted to cooperate for allowing an up draft of air to flow into the cylindrical container 29. The presence of an up draft in the container 29 is adapted to facilitate the ignition of the combustible material without the necessity for soaking the combustible material in volatile chemical substances.
Furthermore, the flow rate of the air draft is adapted to be modulated so as to modulate accordingly the intensity of the combustion occurring in the cylindrical container 29 once the combustible material is ignited.
The flow rate of the air draft may be controlled by a relative rotational displacement between the inner peripheral wall 20 and the outer peripheral wall 24. To modulate the flow rate of the air draft, the intended user grasps the outer wall handles 36 and rotates the outer peripheral wall 24 relatively to the inner peripheral wall 20 so as to modify the relative positioning of each inner wall venting apertures 22 and each adjacent outer wall venting apertures 30 relatively to each other.
* 2152014 One of the main features of the present invention resides in the presence of a means for selectively preventing outside air from reaching the cylindrical container 29 in order to selectively bring the combustion to a halt by depriving the ignited combustible material from oxygen. To halt the combustion of the combustible material, the intended user merely needs to position the lid 46 over the cylindrical container 29 with the lower peripheral edge 52 of the flange 50 embedded in the volume of granular or friable material 44. The embedded lower peripheral edge 52 provided a gas-tight sealing means that leads to the oxygen deprivation of the combustible material and thus to its extinguishment.
The cooking device 10 may be readily carried from one location to another by releasably locking the lid 46 to the base plate 12 and thereafter using the lid handle 54 as a carrying handle.
The lid 46 is releasably locked to the base plate 12 by first positioning the lid 46 over the cylindrical container 29 with the lower peripheral edge 52 of the flange 50 embedded in the volume of granular or friable material 44 and then rotating the lid 46 until the locking prongs 56 are snappingly hooked by the corresponding locking hooks 58.
Numerous modifications, variations and adaptations may be made to the particular embodiments of the invention hereinbefore described without departing from the scope of the invention as defined in the claims.
