Abstract

Some embodiments of the present invention relate to a portable charcoal grill where, in the closed position, charcoal may be supplied through an opened chimney lid located at the top of the grill, and lit paper or other kindling material may be inserted through an opening to an ignition area located at the bottom of the grill in order to ignite the charcoal. The chimney effect created by the shape and directionality of the closed portable grill may aid in heating and igniting the charcoal. Once the charcoal is at the proper burning point, the portable grill may be safely opened up and a large grilling area may be available for cooking. The legs, which can be used as carrying handles for the grill, may be secured in place by a unique joint that has two or more distinct positions.

Claims

1. A portable grill device having a closed position and an open position, said grill comprised of:

a housing, with a plurality of convection openings on at least one surface of said housing, said housing including an outer cover and an inner cover hinged together at one end,

wherein in the closed position, the lower end and the lateral sides of the outer cover overlap and cover the corresponding end and sides of the inner cover;

a collapsible shelf having a substantially horizontal position and a substantially parallel and adjacent position, wherein said shelf is situated inside the grill housing,

wherein in the closed position, the substantially horizontal position of said shelf supports the charcoal and creates a temporary partition to provide a separate ignition area below the charcoal during an ignition process,

in the open position, the substantially parallel and adjacent position of said shelf to the outer cover eliminates the ignition area; and

said shelf automatically rotates between said substantially horizontal, supporting position and a collapsed, prone position when said grill device moves between the closed and open positions, and

a safety cover having a plurality of convection openings dispersed across the surface of said cover for providing aeration for the flames,

wherein in the closed upright position, the interior cavity of the housing creates a single charcoal containment area and the organized placement of the openings on the housing and safety cover manipulates air flow and circulation to enable convection heat transfer throughout said single charcoal containment area causing the charcoal to heat more quickly and efficiently, and in the fully-opened position the outer and inner covers create an enlarged contiguous grilling area;

wherein the safety cover is attached to the hinged end of the inner cover.

4. The device of claim 1, wherein the plurality of convection openings on the housing includes a plurality of small perforations along the housing sides creating convection vents.

5. The device of claim 1, wherein the plurality of convection openings on the housing includes two large openings, one at each side of the housing, situated on lower part of the device, said openings additionally providing access to the ignition area of the device when in the closed position.

6. The device of claim 1, wherein the housing includes a fill mark for indicating the maximum amount of charcoal to be placed in the device when in the closed position.

7. The device of claim 1, further comprising two legs attached to the inner cover, each leg situated at one edge of inner cover, and a third leg attached to the far edge of the outer cover.

8. The device of claim 7, wherein in the closed vertical position, the device sits on the ground and two of the legs support the device for increased stability.

9. The device of claim 7, wherein in the closed horizontal position, the device sits on two of the legs and the third leg functions as a handle for opening or carrying the device.

10. The device of claim 7, wherein in the open horizontal position, the device sits on all three legs.

11. The device of claim 7, wherein the legs are immaterially connected to the housing.

12. The device of claim 7, wherein the legs are attached to the housing using a joint connector, wherein the elasticity of said rod enables said legs to be in a locked position or in free rotation around their axis.

13. The device of claim 7 wherein a joint rod can be stretched to move between at least two positions, including a locked position in which the rod is seated into a drilled-out area of the housing and a free position wherein the rod is seated in a debossment area of the housing.

2. A portable grill device having a closed position and an open position, said grill comprised of:

a housing, with a plurality of convection openings on at least one surface of said housing, said housing including an outer cover and an inner cover hinged together at one end,

wherein in the closed positions, the lower end and the lateral sides of the outer cover overlap and cover the corresponding end and sides of the inner cover;

a collapsible shelf having a substantially horizontal position and a substantially parallel and adjacent position, wherein said shelf is situated inside the grill housing,

wherein in the closed position, the substantially horizontal position of said shelf supports the charcoal and creates a temporary partition to provide a separate ignition area below the charcoal during an ignition process,

in the open position, the substantially parallel and adjacent position of said shelf to the outer cover eliminates the ignition area; and

said shelf automatically rotates between said substantially horizontal, supporting position and a collapsed, prone position when said grill device moves between the closed and open positions, and

a safety cover having a plurality of convection openings dispersed across the surface of said cover for providing aeration for the flames,

wherein in the closed upright position, the interior cavity of the housing creates a single charcoal containment area and the organized placement of the opening on the housing and safety cover manipulates air flow and circulation to enable convection heat transfer throughout said single charcoal containment area causing the charcoal to heat more quickly and efficiently, and in the fully-opened position the outer and inner covers create an enlarged contiguous grilling area;

wherein the safety cover includes a securing mechanism adapted to maintain the safety cover in a locked position while the device is in the closed position, and automatically releasing said safety cover when sufficient pressure is applied by the increasingly obtuse angle of said outer and the inner covers when the device is moved to the open position.

3. The device of claim 2, wherein the securing mechanism is of a louver and lock type.
