Abstract

A portable cooking grill supported on support elements slidable on a series of rods driven into the ground and clamped thereto with eyebolts. In one embodiment, a rectangular enclosure open at the top and bottom surrounds a grill supported at an intermediate height to create a chimney effect aiding in cooking. The enclosure is assembled from separate panels without separate fasteners, and a top may be added to create an oven. In a second embodiment, two rods have forked clamping bars slidable thereon and clamped at a selected height with the eyebolts.

Claims

1. A portable cooking grill comprising:

a plurality of rods adapted to be driven into the ground at spaced apart locations defining a rectangular pattern;

a plurality of support elements comprising a pair of elongated support bars each extending between respective aligned pairs of rods, each of said pair of elongated bars having a vertical hole at each end slidably receiving a rod, a horizontal threaded bore at each end of each support bar, extending into an adjacent vertical hole, and a plurality of bolts, each bolt received in a respective threaded hole to enable clamping of each end of each support bar to a respective rod;

each of said bolts having a finger grippable radially projecting feature thereon so that said support element may be clamped to said rod by advance of each of said bolts in said threaded bore to engage a respective rod; and

,

a cooking grill resting on said support elements at an adjusted height set by the height at which said support bars are clamped to said rods by said bolts.

2. The portable cooking grill according to claim 1 wherein said bolts comprise eyebolts.

3. The portable cooking grill according to claim 1 further including a pair of cross bars each extending between adjacent ends of said support bars, said cross bars received over said bolts which extend endwise in each end of said support bars.

4. The portable cooking grill according to claim 3 further including a wing nut threaded onto each bolt and able to be tightened onto said cross bars.

5. The portable cooking grill according to claim 1 further including an enclosure open at the top and bottom also supported on said support bars surrounding said grill.

6. The portable cooking grill according to claim 5 wherein said enclosure includes portions extending substantially above and below said grill.

7. The portable cooking grill according to claim 6 further including a separate top positioned on said top of said enclosure to create an oven.

8. The portable cooking grill according to claim 6 wherein said enclosure comprises separate side panels each extending across respective ends of said support bars, and separate front and rear panels supported on front and rear edges of said side panels.

9. The portable cooking grill according to claim 6 wherein said enclosure extends several inches above and below said grill.

10. The portable cooking grill according to claim 8 wherein said front and rear panels each have a rolled top edge and said side panels each have inwardly turned corner flanges, said top edges hooked over said corner flanges to support said front and rear panels on said side panels.

11. The portable cooking grill according to claim 10 wherein said rods extend upwardly outside said side panels to confine said side panels therebetween.

12. The portable cooking grill according to claim 10 wherein said front and rear panels are assembled within said corner flanges to be confined therein.

13. The portable cooking grill according to claim 12 wherein said front and rear panels are assembled within said corner flanges to be confined therein.

14. The portable cooking grill according to claim 8 wherein each said side panels include a top portion formed with said cover flanges and also include skirt portions extending below said support bars and grill disposed thereon.

15. The portable cooking grill according to claim 14 wherein said cross bars have central notches, and said skirt portions of said side panels comprise a pair of spaced apart panels having a gap aligned with said notches, whereby a spit can be supported and extend within said enclosure.

16. The portable cooking grill according to claim 14 wherein each said side panels include a top portion formed with said cover flanges and also include skirt portions extending below said support bars and grill disposed thereon.

17. The portable cooking grill according to claim 1 wherein two rods are included, and each support element comprises a forked clamping bar portion of substantial width gripping said grill so as to prevent rotation thereon.

18. A portable cooking grill assembly comprised of a rectangular boxlike enclosure formed by four connected side panels and open at a top and bottom of said four side panels to form a chimney-like structure;

a rod at each corner of said enclosure supporting said enclosure spaced above the ground so as to enable an open fire to be built and maintained beneath said enclosure; and

,

a grill comprised of an array of spaced apart bars, said grill defining a support for food cooking, said grill mounted within said enclosure at an intermediate level, located several inches from each of said top and bottom of said four side panels forming said enclosure, whereby a draft effect induces a vertical flow of gases heated by said fire to flow up and through said enclosure and past said grill mounted at an intermediate level therein to establish consistent cooking conditions for food supported on said grill.

19. The portable cooking grill according to claim 18 wherein said enclosure comprises separate side panels each extending across respective ends of said support bars, and separate front and rear panels supported on front and rear edges of said side panels.

20. The portable cooking grill according to claim 19 wherein said front and rear panels each have a rolled top edge and said side panels each have inwardly turned corner flanges, said top edges hooked over said corner flanges to support said front and rear panels on said side panels.

21. The portable cooking grill according to claim 20 wherein said rods extend upwardly outside said side panels to confine said side panels therebetween.

22. A portable cooking grill comprised of a rectangular boxlike enclosure open at the top and bottom;

a rod at each corner of said enclosure supporting said enclosure spaced above the ground so as to enable an open fire to be built and maintained beneath said enclosure;

elongate support bars extending between aligned pairs of rods and secured at each end thereof to a respective rod, said enclosure resting on said support bars; and

,

a cooking grill supported within said enclosure at an intermediate level, several inches from both a top and bottom of said enclosure, whereby a chimney effect induces a vertical flow of gases heated by said fire to flow through said grill to establish consistent cooking conditions on said grill.
