A burner 371 is installed within the cooking base 31 and is connected to a fuel connector 372 mounted on and disposed externally of the cooking base 31 via a fuel pipe 43 that extends therebetween. The fuel connector 372 is adapted to be connected to a fuel source (not shown) to permit the supply of fuel to the burner 371 within the cooking base 31.
Each of the [0019] top cover 32 and the cooking base 31 is generally rectangular in shape. The cooking base 31 has a bottom wall 311, front and rear side walls 312, 317 and left and right side walls 316 that extend upwardly from the bottom wall 311. The top cover 32 has a rear edge 322 hinged to an upper edge of the rear side wall 317 of the cooking base 31 by means of a pair of pivot lobe units 325 secured to the rear side wall 317 and a pair of pivot shafts 52. The top cover 32 further has a front edge 321 opposite to the rear edge 322, and left and right edges 323 interconnecting the front and rear edges 321, 322. The fastening members 38 are provided on the front edge 321 of the top cover 32 and the front side wall 312 of the cooking base 31 for releasably fastening together the front edge 321 of the top cover 32 and an upper edge of the front side wall 312 of the cooking base 31. Each fastening member 38 includes inter-engageable fastening parts 381, 382 fixed respectively to the front edge 321 of the top cover 32 and the front side wall 312 of the cooking base 31. The handle 33 is secured to the top cover 32 adjacent to the front edge 321. The handle 33 has a pair of connecting end portions 331 connected to the top cover 32, and a gripping portion 332 extending between the connecting end portions 331 and spaced apart from the front edge 321 of the top cover 32 so as to define a finger opening 333. The upper edge of the rear side wall 317 of the cooking base 31 is formed with a draining notch 314 adapted for draining liquid, such as oil generated during use of the cook unit 3, from the cooking base 31.
A pair of [0020] side racks 35 are mounted on the left and right side walls 316 of the cooking base 31. Each of the side racks 35 has a first end portion 351 and a second end portion 352 opposite to the first end portion 351 and extending from the first end portion 351 in a first direction. The first end portion 351 is forked so as to form a pair of pivot portions 351 a and an opening 351 b between the pivot portions 351 a. The pivot portions 351 a are mounted pivotally on an upper edge of a respective one of the left and right side walls 316 of the cooking base 31 by means of a pair of pivot shafts 36 that extend through a pair of pivot lobes 315 provided on the respective one of the left and right side walls 316 of the cooking base 31. The second end portion 352 of each of the side racks 35 is formed with a plurality of hook projections 355 for hooking of various barbecue utensils (not shown) thereon. Each of the side racks 35 is mounted with a respective handle bar 353 at the first end portion 351 thereof. Each of the handle bars 353 is substantially U-shaped, and has a pair of connecting sections 353 a connected fixedly and respectively to the pivot portions 351 a of a respective one of the side racks 35, and a gripping section 353 b interconnecting the connecting sections 353 a. Each of the handle bars 353 extends from the respective one of the side racks 35 in a second direction generally transverse to the first direction. That is, the handle bars 353 are generally transverse to the side racks 35. To use the cook unit 3, the top cover 32 is released from the cooking base 31 and is turned upwardly for uncovering the top side of the cooking base 31, and the side racks 35 are unfolded from the cooking base 31 so as to be disposed in a substantially horizontal orientation on left and right sides of the cooking base 31 and adjacent to the left and right side walls 316 of the cooking base 31, respectively. At this time, the handle bars 353 are oriented downwardly and abut against the left and right side walls 316 of the cooking base 31 for supporting the side racks 35 in the unfolded position, as shown in FIG. 6. The fuel connector 372 is disposed in the opening 351 b when the right side one of the side racks 35 is turned to the unfolded position (see FIG. 4).
Referring to FIGS. 5 and 7, when it is desired to store the barbecue grill assembly of the present embodiment after use, the side racks [0021] 35 are turned inwardly into the cooking base 31 for moving to a folded position, in which the side racks 35 are disposed within the cooking base 31 above the grill member 34. The top cover 32 is then turned toward the cooking base 31 for covering the side racks 35 and the top side of the cooking base 31. Each of the left and right edges 323 of the top cover 32 has a pair of recessed portions 324 for accommodating the forked first end portion 351 of a respective one of the side racks 35 such that the top cover 32 can be disposed fittingly on top of the cooking base 31 for covering the same when the side racks 35 are disposed in the folded position. At this time, the handle bars 353 on the side racks 35 are oriented upwardly and are disposed externally of the cooking base 31 and the top cover 32 to permit gripping thereat for handling the cook unit 3. Then, the top cover 32 is fastened to the cooking base 31 via the fastening members 38. The cook unit 3 can be carried by gripping at the handle bars 353 using both hands of the user or by gripping at the handle 33 using one hand of the user.
