DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(10) Various aspects of the present application well evolve from the following detailed description of the preferred embodiments thereof which should be referenced to the prior delineated drawings.

(11) The barbecue apparatus as a whole is depicted in the drawings by reference character 10.

(12) With reference to FIG. 1, it may be observed that apparatus 10 includes, as one of its elements, a stand 12 having a ground contacting portion 14 and an outwardly extending portion 16, including a frame 18.

(13) Ground contacting portion 14 is provided with a platform 20 supported above ground surface 22 by removable legs 24, 26, 28, and 30, FIGS. 1 and 3. With reference to FIG. 6, it may be observed that a top plan view of exemplary leg 24 is depicted and is typical of the construction of legs 26, 28, and 30. Leg 24 includes a bracket 34 which is welded to platform 20 at weld line 36. An elongated square tube 38 slidingly engages the interior of bracket 34 and is held thereto by a pin 40. A spreadable retaining spring 42 (directional arrows 43) holds pin 40 in place and allows the removal of pin 40 when elongated square tube 38 is to be removed from bracket 34 for storage. Needless to say, the square tubes of legs 26, 28, and 30 are removed in a similar manner for storage.

(14) Frame 18 of outwardly extending portion 16 of stand 12 is formed with hollow vertical members 42 and 44 and a hollow/contiguous cross member 46. Frame 18 rests on and is removable from surface 48 of platform 20. For example, hollow frame member 44 slips over a supporting stud 45 and is held thereto by removable pin 47, FIG. 2. Frame member 42 is similarly formed. Thus, frame 18 may be removed for storage when apparatus 10 is not in use.

(15) A tray 50 is employed in apparatus 10 and is constructed to hold open grill 52. Tray 50 and held grill 52 may initially rest or locate adjacent to surface 48 of platform 20. As may be apparent hereinafter, tray is freely movable relative to ground surface contacting portion 14 of apparatus 10. Open grill 52 receives heat from ignited fuel source 88.

(16) Apparatus 10 further possesses a height adjuster 54 for positioning tray 50 and open grill 52 at a certain distance relative to ground surface 22. Height adjuster 54 is formed with cables 56 and 58 that may be of aircraft grade. Cables 56 and 58 are connected to a rotatable shaft 60 which is linked to a removable crank 62. Rotatable shaft 60 may be turned relative to supporting frame 16. FIG. 5 details the interconnection between removable crank 62 and rotatable shaft 60. As may be observed, an internally threaded boss 64 engages a threaded extension 66 of crank 62. Wing nut 68 holds crank 62 to internally threaded boss 64 when in use. Further, internally threaded boss connects to rotatable shaft 60 through frame member 44 such that the turning of crank 62, directional arrow 70, also rotates internally threaded boss and rotatable shaft 60. Such movement wraps and unwraps cables 56 and 58 about rotatable shaft 60 and positions tray 50 and open grill 52 at a certain distance relative to ground surface 22.

(17) With reference to FIG. 2, it may be observed that tray 50 and open grill 52 have been raised from a resting position on or near surface 48 of platform 20 to a position at a certain distance above ground surface 22. Cables 56 and 58 are shown partially wrapped about shaft 60 due to the turning of crank 62.

(18) Referring to FIG. 7, it may be seen that cable 58 connects to tray 50 by the use of a ring 72 which has been welded to tray 50. Guides 74 and 76 stabilize the positioning of tray 50 in its movement upwardly or downwardly along vertical members 42 and 44. With reference to FIG. 4, it may be seen that exemplary guide 76 is fashioned by L-shaped members 78 and 80 that are welded to tray 50 and, thus, moves along vertical member 44 with tray 50. Guide 74 is similarly fashioned.

(19) A brake 82 is also found in apparatus 10 for arresting the rotational movement of shaft 60. With respect to FIG. 8, it may be apparent that shaft 60 extends through vertical member 42 of frame 18 and terminates in a flange 84. A spring 86 circumvents shaft 60 and is positioned between flange 84 and vertical member 42. Spring 86 frictionally engages flange 84, vertical member 42, and rotatable shaft 50 to an extent that allows the rotation of shaft 60 by crank 62, but prevents the counter rotation of shaft 50 when crank 62 is released.

(20) In operation, the user of barbecue apparatus 10 provides selective fuel 88 below platform 20 atop ground surface 22. Igniting fuel 88 produces heat which rises up to grill 52 to cook a foodstuff. Fuel 88 may take the form of any wood based substance, such as chips, branches, charcoal, and the like. Grill 52 within tray is then positioned above ground surface 52 by the use of height adjuster 54, specifically by the turning of crank 62. Brake 82 retains grill 52 in the desired position above ground surface while foodstuffs are cooked on grill 52. Directional arrow 90, FIG. 2, shows the movement of tray 50 and grill 52 upwardly from a position on or adjacent to surface 48 of platform 20. Thus, the movement of tray 50 and grill 52 controls the cooking temperature for foodstuffs located on tray 52. Apparatus 10 may be easily assembled and disassembled for storage by removing legs 24, 26, 28, and 30 and frame 16 from platform 20. Crank 62 is also removable and connected to rotatable shaft by loosening wing nut 68 and operating the threaded engagement of boss 564 and extension 66.

(21) When stacked, the disassembled components of barbecue apparatus occupy a compact storage space of approximately 24 inches (61 cm) in width, 20.25 inches (51.4 cm) in depth, and 4.5 inches (11.4 cm) in height.

(22) While in the foregoing embodiments of the application have been set forth in considerable detail for the purposes of making a complete disclosure of the invention, it may be apparent to those of skill in the art that numerous changes may be made in such detail without departing from the spirit and principles of the application.
