Abstract

A portable cooking grill is configured with a collapsible frame having a pair of frame sections extending outwardly and downwardly from a pair of foldably connected grill sections to allow the user to adjust the height of the grilling surface and the frame width. Each frame section has a pair of telescoping legs pivotally connected to the ends of side support rails. The side support rails have a downwardly facing U-shaped channel which receives one of the legs therein. For storage, the legs are telescopically collapsed and then folded into the channel, the support rails are received in a tubular section of the grill sections and the grill sections are folded together. The legs have a securing mechanism to secure the legs at the height desired by the user. A engagement mechanism secures the side support rails in the retracted or extended, or therebetween, position relative to the grill sections.

2. The portable cooking grill according to claim 1 further comprising a second grill section disposed between said first grill section and said second frame section, said second grill section having a first end at said second frame section, a second end foldably connected to said second end of said grill section, a first side and a second side.

3. The portable cooking grill according to claim 2, wherein said second grill section has a tubular section at each of said first side and said second side thereof, said tubular section sized and configured to receive said side support rails of said second frame section therein.

4. The portable cooking grill according to claim 3, wherein said tubular section is open at said first end of said first grill section to slidably receive said side support rails of said first frame section therein and open at said first end of said second grill section to slidably receive said side support rails of said second frame section therein.

5. The portable cooking grill according to claim 2 further comprising a hinge interconnecting said second end of said first grill section and said second end of said second grill section.

6. The portable cooking grill according to claim 1, wherein said legs are configured to pivot from inside said channel in said second position to downward projecting in said first position.

7. The portable cooking grill according to claim 1, wherein at least one of said first grill section and said second grill section has a plurality of substantially parallel disposed grate rods interconnecting said first side and said second side thereof.

8. The portable cooking grill according to claim 1, wherein each of said legs comprises a first leg member and a second leg member in telescoping cooperation with said first leg member.

9. The portable cooking grill according to claim 8 further comprising means for securing the position of said second leg member relative to said first leg member.

10. The portable cooking grill according to claim 1, wherein said tubular section is open at each of said first end and said second end of said first grill section and said side support rails are slidably received in said tubular sections.

11. The portable cooking grill according to claim 1 further comprising engagement means interconnecting said first grill section and each of said side support rails for securing said side support rails relative to said first grill section.

12. A portable cooking grill, comprising:

a frame having a first frame section and a second frame section, each of said first frame section and said second frame section comprising one or more legs and one or more side support rails, each of said legs having a first end, a second end, a first leg member and a second leg member in telescoping cooperation with said first leg member, each of said side support rails having a first end, a second end and a channel disposed between said first end and said second end of said side support rails, said first end of said legs pivotally connected to said first end of said side support rails, said channel sized and configured to receive one of said legs therein;

a first grill section having a first end, a second end, a first side and a second side; and

a second grill section having a first end, a second end, a first side and a second side, said second end of said first grill section foldably connected to said second end of said second grill section, at least one of said first grill section and said second grill section having a tubular section at each of said first side and said second side thereof, said tubular section sized and configured to slidably receive said side support rails therein,

wherein said legs are received in said channels and said side support rails are received in said tubular section so as to pivot and collapse said frame between a first position extended and open for cooking and a second folded position closed for storage said first grill section and said second grill section defining a grilling surface when said frame is in said first position.

13. The portable cooking grill according to claim 12, wherein both of said first grill section and said second grill section has said tubular section at said first side and said second side thereof.

14. The portable cooking grill according to claim 13, wherein said tubular section is open at said first end of said first grill section to slidably receive said side support rails of said first frame section therein and open at said first end of said second grill section to slidably receive said side support rails of said second frame section therein.

15. The portable cooking grill according to claim 12 further comprising a hinge interconnecting said second end of said first grill section and said second end of said second grill section.

16. The portable cooking grill according to claim 12, wherein said legs are configured to pivot from inside said channel in said second position to downward projecting in said first position.

17. The portable cooking grill according to claim 12 further comprising means for securing the position of said second leg member relative to said first leg member.

18. The portable cooking grill according to claim 12 further comprising engagement means interconnecting said first grill section and each of said side support rails of said first frame section and interconnecting said second grill section and each of said side support rails of said second frame section for securing the position of said side support rails relative to said first grill section and said second grill section.

19. A portable cooking grill, comprising:

a frame having a first frame section and a second frame section, each of said first frame section and said second frame section comprising a pair of legs and a pair of side support rails, each of said legs having a first end, a second end, a first leg member and a second leg member in telescoping cooperation with said first leg member, each of said side support rails having a first end, a second end and a substantially U-shaped channel disposed between said first end and said second end of said side support rails, said first end of said legs pivotally connected to said first end of said side support rails, said channel sized and configured to receive one of said legs therein;
