Collapsible cooking device
First Claim
1. A collapsible portable cooking stove comprising:
- a pair of substantially rectangular first side plates, each first side plate comprising;
a port configured to allow airflow and combustion, the port extending from a top edge of the first side plate toward a bottom edge of the first side plate, the bottom edge being opposite the top edge;
a mating tab extending from a side edge of each first side plate, the mating tab extending laterally away and along the side edge in a first direction to form a tab slot having a bottom; and
a locking tab having a bottom surface extending continuously and laterally away from and along the side edge to a tip and in a second direction opposite the first direction; and
a pair of substantially rectangular second side plates, each second side plate comprising;
a mating slot disposed near a side edge of each second side plate and configured to receive the mating tab of one of the pair of first side plates for engagement, the mating slot being positioned on each second side plate such that a top of the mating slot is aligned with the bottom of the tab slot when one of the pair of second side plate is engaged and horizontally aligned with one of the pair of first side plates; and
a locking slot configured to engage the bottom side of the locking tab of one of the pair of first side plates to form a force-fit interaction, the locking slot being positioned on each second side plate such that a bottom of the locking slot is slightly above the tip of the locking tab when one of the pair of second side plates is engaged and horizontally aligned with one of the pair of first side plates;
wherein;
engagement of the locking slot and the locking tab deforms the locking tab or stretches the side edge of one of the second side plates to allow the bottom of the locking slot to slip over the tip of the locking tab;
engagement of the locking slot and the locking tab opposes shifting motion in the first direction by the pair of second side plates relative to the pair of first side plates thereby allowing application of a lifting force to the pair of second side plates without disengaging the pair of second side plates; and
the first and second side plates are collapsible and stackable into a substantially flat configuration by disengaging the locking slot and tab and shifting the pair of second side plates relative to the pair of first side plates.

Abstract
A fire-resistant collapsible enclosure can include three or more sidewalls coupled with a cross plate internal to the enclosure. A top portion of the enclosure can include a non-linear edge configured to be an airflow outlet, or a bottom portion of the enclosure can include a non-linear edge configured to be an airflow outlet. The fire-resistant collapsible enclosure can be configured for use as an oven, a stove, or a smoker. In an example, two or more of the fire-resistant collapsible enclosures can be used together, such as where one enclosure is configured as a heat source and a second enclosure is configured as a smoker. In an example, the cross plate can include a throttle to control airflow through the enclosure.

2. A heating apparatus, comprising:
-
a fire-resistant collapsible enclosure comprising; a plurality of substantially vertical sidewalls having an assembled position defining an outer perimeter of the apparatus and an enclosure volume; each sidewall including; a bottom edge having a plurality of extensions protruding therefrom configured to support the sidewall and form an airflow inlet between the plurality of extensions defining an inlet area; and a top edge having an extension protruding therefrom, the extension of the top edge comprising; a slot configured to receive a cross member; and a recess configured to support a grate; wherein a sidewall of the plurality of sidewalls comprises a side edge having; a mating tab extending along and laterally away from the side edge in a first direction; and a locking tab having a bottom surface extending continuously and laterally away from the side edge in a second direction opposite the first direction; wherein another sidewall of the plurality of sidewalls comprises; a mating slot configured to receive the mating tab of the sidewall for engagement; and a locking slot configured to engage the bottom side of the locking tab of the sidewall to form a force-fit interaction; wherein the extensions of the top edge form a plurality of airflow ports defining an outlet area; a first cross plate coupled with the substantially vertical sidewalls at an intermediate location between the top and bottom support portions and configured for supporting a fuel above the airflow ports; a second cross plate coupled with the substantially vertical sidewalls and arranged above the airflow ports; wherein the airflow ports are in fluid communication and are configured to allow airflow through the enclosure; and wherein a ratio of a port area to the enclosure volume can be readjusted by blocking all or a portion of the plurality of airflow ports. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16)
