Abstract

A collapsible unit for supporting food items over a heat source comprises a collapsible frame enclosure wherein at least one side of the frame is reconfigurable to enable various types of cooking and heating arrangements.

Claims

1. A device facilitating the heating of items, the device comprising:

at least one grill for supporting an item to be heated; and

a collapsible frame for suspending the grill above a heat source, the frame having a plurality of vertical sides, at least one of the vertical sides being designated as a first side having user-selectable variable construction and the sides other than the designated first side collectively constituting the remainder of the frame;

wherein the first side having user-selectable variable construction is constructed Of at least one panel selected by a user from among a plurality of panels available for constructing the first side by being removably attached to the remainder of the frame;

and wherein the at least one panel directly supports the grill;

and wherein the remainder of the frame attaches to at least one combination of multiple ones of the available panels vertically stacked along the first side;

and wherein the available panels exhibit different vertical heights when applied to the frame and Wherein the designated first side is selectively constructed by a user to include a panel of specific height by which the user adjusts at least one of;

how much of the first side of user-selectable variable construction is substantially enclosed or at what height the grill is supported by the frame.

2. The device of claim 1 wherein the device operates in at least one user-selectable in-use configuration wherein the first side having user-selectable variable construction is constructed with fewer than all of the available panels that are able to be used on the first side concurrently and any unused panels from the plurality of available panels are entirely excluded from the construction of the first side having user-selectable variable construction.

3. The device of claim 1 wherein a vertical position at which the at least one panel selected by the user is attached to the remainder of the frame is selectable by the user from among more than one possible such position of attachment.

4. The device of claim 3 wherein the position of attachment of the panel changes at least one of:

a proportion of the first side that is substantially enclosed, which portion of the first side is substantially enclosed by the panel, or a height above the heat source at which the grill is supported by the frame.

5. The device of claim 1 wherein the first side having user-selectable variable construction is constructed of a first quantity of panels to establish a first value of a variable attribute and alternatively constructed of a second quantity of panels to establish a second value of the variable attribute, the variable attribute being at least one of a proportion of the first side that is substantially enclosed or a height above the heat source at which the grill is supported by the frame.

6. The device of claim 1 wherein the first side having user-selectable variable construction is constructed to comprise a first panel and a second panel, the first and second panels having different heights, wherein, in attaching the first and second panels to the remainder of the frame, the first panel is placed above the second panel to support the grill at a first height and the first panel is placed below the second panel to support the grill at a second height different from the first height.

7. The device of claim 1 wherein the first side having user-selectable variable construction comprises first and second panels, both concurrently attached to the remainder of the frame, and the grill is user-selectable to either be directly supported by the first panel in accordance with a first user-selectable configuration or to be directly supported by the second panel in accordance with a second user-selectable configuration.
