     SUMMARY OF THE INVENTION 
     According to the present invention, a portable barbecue grill includes a rounded fire bowl, a cooking grill removably supported within the fire bowl top and pairs of inverted U-shaped foldable legs. The first or outer pair of legs is pivotably connected at its top to the bottom of the fire bowl with its free leg ends depending. The second or inner pair of legs is pivoted at its shank portion to the shank portion of the pair of outer legs. A leg clip affixed to the bottom surface of the fire bowl resiliantly engages the pair of inner legs at its top so as to releaseably secure the inner pair of legs to the fire bowl bottom with the shank portions of the outer and inner legs intersecting beneath the fire bowl.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     In FIG. 1 portable grill 10 is illustrated as including rounded fire bowl 12, cooking grill 13, outer pair of inverted U-shaped legs 16 and inner pair of inverted U-shaped legs 14. 
     In FIG. 2 pairs of legs 14, 16 are illustrated as folded in parallel with the bottom of rounded fire bowl 12 for portability or storage. 
     A modified version is illustrated in FIG. 3 embodying a removable cover 18 having insulated carrying handle 20, cover vent 22, removable grill 13 and rigid legs 17. 
     In FIG. 4, fire bowl 12 is illustrated as including upper outwardly extending flange 15, together with pairs of lower dimples 26, 28 and 32, 36. Upper dimples 30, 34 are superposed with respect to pairs of lower dimples 26, 28 and 32, 36 respectively. Also, upper dimples 38, 40 are provided on opposed sides such that cooking grill 13 may be snap fitted into the fire bowl assembly. 
     Cooking grill 13 is illustrated in FIG. 7 as including peripheral member 44, a plurality of smaller rods 42 butt welded at their ends to perimeter 44 and peripheral portion transverse support rod 46. Cooking grill 13 is snap fitted into fire bowl 12 such that the grill lower portion is supported upon lower dimples 26, 28 and 32, 34 while the upper portion of peripheral portion 44 is snap fitted beneath the upper dimples 30, 38 and 40. 
     In FIG. 8, the pairs of inverted U-shaped outer legs 16 and inner legs 14 are shown as pivoted at their shank portions by means of pins 48, 50. 
     In FIG. 9 resilient clip 52 is illustrated as including top portion 56 are secured to the bottom of fire bowl 10 by means of hole 54 and conventional stove bolt or the like extending through hole 54 into the bottom of fire bowl 10 and closed on the bottom outside of fire bowl 16 by means of a lock nut or the like. A resilient free end 58 is curled upon itself and engages the top portion of the pair of inner legs 14, so as to releasably secure the top of the pair of inner legs apart from the top of outer legs 16. 
     In FIG. 10, pivoting clip 60 is illustrated as including flat portion 62 secured to the bottom of the fire bowl by means of bolts extending through aligned holes 66, 64 and locked by conventional lock nut on the bottom outside of fire bowl 10. One or more clips 60 may be secured to the bottom of fire bowl 10, such that the top of the outer pair of legs 16 is pivotably secured and that the pairs of legs 14, 16 may be pivoted from the intersecting and supporting position illustrated in FIG. 1 to the folded storage or portability position illustrated in FIG. 2. 
     Manifestly, folding legs 14, 16 provide for easy portability and storage, while snap-in grill 13 is locked between the upper and lower dimples. In one prototype, 380 square inches of cooking area are provided, while top of the inner pair of legs 14 is resiliently snapped into clip 52. This snap-in of inner legs 14 provides a rigid support, yet integrated disassembly to the parallel position shown in FIG. 2 for carrying and storage. The simplicity of the device is in contrast to a sophisticated cooking capability, and easy portability in storage. 
     FIG. 11 depicts hanger bracket 68 which may be secured to the fire bowl side by means of conventional bolt and lock nut (not illustrated), extending through hole 17 defined in flat portion 70. 
     Manifestly, the snap-in feature and folding of the legs may be varied without departing from the spirit and scope of the invention.
