Abstract

It is an object of the present invention to provide a portable cooking grill of the kind intended for use outdoor charcoal cooking. In one embodiment, the grill according to the invention may be relatively small and easily carried on camping hikes. In another embodiment, the grill of the invention is completely collapsible but is useful as a large multipurpose apparatus for use in charcoal cooking for a large number of people. The invention provides adjustable features, including at least one grill unit and/or a cooking pan which can be handled while hot but very safely. Moreover, the supporting frame of the grill and the added cooking members such as grill units, pans or the like are structured to permit these added members to be placed in horizontal or inclined positions and at preselected levels above the ground. Yet another object of the invention is to provide adjusting means including handle bars attached to the cooking pan so that it can be easily repositioned or removed from the grill frame in a safe and secure manner.

Claims

1. A portable cooking device comprising:

a knockdown supporting frame having four leg members extending upwardly from the ground to provide the four corner positions of a rectangel, as viewed on a horizontal plane passing through the frame, and

two parallel crosspieces, each of which connects upper corner positions between any of two opposing leg members, respectively;

a plurality of studs mounted at intervals along each of said leg members to protect a short distance from said corner positions at preselected levels above the ground;

at least one removable cooking pan constructed and arranged to be held in a substantially horizontal position by said crosspieces or in a horizontal to inclined position by a set of said studs in pairs located at the same or different preselected levels above the ground; and

adjusting means including a plurality of bars attached to said pan for flexible movement substantially laterally thereof, said bars extending longitudinally beyond each of the four corner position, respectively, for support on said projecting studs when in a closed position and being movable upwardly or downwardly free of said studs when flexed laterally to an open position.

2. A portable cooking device as claimed in claim 1, including a grill unit with means for attaching it to at least one of said parallel crosspieces.

3. A portable cooking device as claimed in claim 2 wherein said grill unit is removably attached to at least one of said parallel crosspieces by clamping means.

4. A portable cooking device as claimed in claim 3 wherein said grill unit is attached to one of said parallel crosspieces by a releasable hook means.

5. A portable cooking device as claimed in claim 1, wherein said cooking pan fits within the studs at the four corner positions of said frame.

6. A portable cooking device as claimed in claim 1, including a flat griddle sheet sufficiently large to cover and completely enclose the interior of the cooking pan.

7. A portable cooking device as claimed in claim 1 wherein each bar is equipped on its longitudinal extension with an insulating handle grip.

8. A portable cooking device as claimed in claim 1 wherein said four legs are incorporated into a free-standing box frame.

9. A portable cooking device as claimed in claim 8 wherein the entire frame is formed of a single length of wire or rod.

10. A portable cooking device as claimed in claim 8, including a grill unit with means for attaching it to said two parallel crosspieces.

11. A portable cooking device as claimed in claim 1 comprising two pairs of separate leg members, each pair being joined at the top by a crosspiece and each leg having a downwardly extending staking portion adapted to be forced into the ground, and a grill unit with means for attaching it to the two parallel crosspieces.

12. A portable cooking device comprising:

a knockdown supporting frame having four leg members extending upwardly from the ground to provide the four corner positions of a rectangle as viewed on a horizontal plane passing through the frame, and

two parallel crosspieces, each connecting upper corner positions of said leg members at the front and back of the frame, respectively;

a plurality of studs mounted at spaced intervals along each of said leg members to project a short distance from said corner positions at preselected levels above the ground;

a removable grill unit fitting onto and being supported by said crosspieces in an approximately horizontal position between the upper front and back of the frame;

a cooking pan adapted to be positioned predominately within the four corners of said frame; and

adjusting means including four bars attached to said pan for flexible movement substantially laterally thereof, said bars extending longitudinally beyond each of the four corner positions, respectively, for support on said projecting studs when in a closed position and being movable upwardly or downwardly free of said studs when flexed laterally to an open position.

13. A portable cooking device as claimed in claim 12 wherein each bar is equipped in its longitudinal extension with an insulting handle grip.

14. A portable cooking unit as claimed in claim 12, wherein the four leg members extend upwardly at an angle from the ground to cross each other in pairs to provide a collapsible X-frame with pivot means at the point of crossing to lock the frame in a standing position.

15. A portable cooking unit as claimed in claim 12, wherein said grill unit is removably attached to at least one of said parallel crosspieces by clamping means.

16. A portable cooking unit as claimed in claim 15, wherein said grill unit is attached to one of said parallel crosspieces by a releasable hook member.

17. A portable cooking unit as claimed in claim 12, including a flat cover member fitting over and sufficiently large to cover and completely enclose the interior of the cooking pan.

18. A portable cooking unit as claimed in claim 17, wherein said cover member fits slidably onto the pan from either end for storage and is dimensioned so as to be received as a separate cooking unit for support on said projecting studs within said frame.

19. A portable cooking unit as claimed in claim 12, including at least one additional flat cooking unit, said frame providing a sufficient number of studs and spaced intervals along each leg member to support such cooking units both above and below said cooking pan.

20. A portable cooking unit as claimed in claim 12, wherein said adjusting bars are attached to the cooking pan along a short inner center section thereof and then extend outwardly of said leg members to rest on outwardly projecting studs.
