ADJUSTABLE OUTDOOR COOKING ASSEMBLY

Abstract

An outdoor cooking assembly includes a plurality of poles configured to support a cooking grate above an open fire. The grate is connected to the poles by a lockable adjustment mechanism that allows a user to adjust the height of the grate above the fire. The adjustment mechanism includes a plurality of sleeves that may be attached directly to the grate, or to a frame that supports the grate from below, and that are slidable on the support poles. The assembly also includes a releasable locking mechanism for preventing unintentional sliding movement of each sleeve along its pole, a locking tool allowing a user to manipulate the locking mechanism without touching locking mechanism, and a grasping tool allowing the user to reposition the grate without physically contacting the grate.

DETAILED DESCRIPTION

[0017] As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention that may be embodied in various and alternative forms. The figures are not necessarily to scale; some features may be exaggerated or minimized to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ the present invention.

[0018] FIG. 1 shows a portable outdoor cooking assembly 10 according to the present disclosure being used to grill various foods over an open fire. The assembly 10 includes an upper grate 14, which may be used to cook vegetables or other foods that burn easily (or to warm food that has already been cooked), and a lower grate 18, which may be used to cook foods such as meats that require higher heats. One of the grates 14, 18 may be removed if a small amount of only one type of food is being cooked or, alternatively, one or more additional grates may be added if more food is being cooked.

[0019] Each grate 14, 18 comprises an outer perimeter 20 and a grid formed from a plurality of horizontally extending bars 22. Both the outer perimeter 20 and the horizontally extending bars 22 are manufactured from a fire-resistant, non-combustible material such as steel, stainless steel, titanium, or combinations thereof. The grates 14, 18 are supported above the fire 12 by a plurality of vertically extending support poles 24 that are preferably manufactured from the same or similar material(s) as the grates 14, 18.

[0020] An upper adjustment mechanism 26 allows the height of the of the upper grate 14 to be adjusted, and a lower adjustment mechanism 28 allows the height of the lower grate 18 to be adjusted. As best seen in FIGS. 2 and 3, the upper adjustment mechanism 26 includes an upper frame 30 that extends below the upper grate 14. The upper frame 30 has opposite sides defined by a pair of spaced apart side bars 32, 34, and opposite ends defined by a pair of end bars 36, 38 that extend at right angles to the side bars 32, 34. A central bar 40 extends horizontally between the side bars 32, 34. Other bars may be added if needed to reinforce the frame 30. The frame 30 may also be constructed in other shapes than the square or rectangular shape illustrated, provided its dimension and strength are sufficient to hold the weight of the upper grate 14 and any food supported on it.

[0021] A plurality of cylindrical sleeves 42 is provided on the exterior of the upper frame 30. Each sleeve 42 is carried by a different one of the support poles 24, and has an inner diameter slightly larger than the outer diameter of the associated pole 24, allowing it to slide freely along the pole 24 for adjustment purposes. A releasable locking mechanism 44 is provided on each sleeve 42 for preventing sliding movement of the sleeve 42 when the adjustment is complete. In the illustrated embodiment, the releasable locking mechanism 44 comprises an externally threaded set screw 46 that extends through an internally threaded bore in a boss 48 formed on a side of the sleeve 42. Other locking mechanisms such as friction clips or pin/receptacle assemblies may also be used.

[0022] The cooking assembly 10 also includes a locking tool 49 configured to cooperate with the locking mechanism 44 to lock or unlock the sleeve 42 as needed. In the illustrated embodiment, the locking tool 49 comprises a screwdriver having an elongated shaft 50 with a tip 52 that engages the head of the set screw 46. A thermally insulating handle 54 at the proximal end of the shaft 50 protects the user's hand from exposure to high temperatures while locking or unlocking the sleeve 42. Other type of locking tools may also be used, depending on the type of locking mechanism used, provided that the tools are sufficiently long and thermally insulating to protect the user.

[0023] As shown in FIG. 5, the lower adjustment mechanism 28 preferably includes a lower frame 50 that is similar or identical in structure to the upper frame 30. That is, the lower frame 50 includes side bars 52, 54, end bars 56, 58, a central bar 60, and cylindrical sleeves 62 having locking mechanisms 64, similar or identical to their counterparts in the lower frame 30. A grasping tool 66 is provided to allow a user to change the position of the lower frame 50 relative to the upper frame 30, without exposing the user to extremely high temperatures.

[0024] As best seen in FIG. 4, the grasping tool 66 comprises an elongated strip 70 of steel or other material capable of withstanding high temperatures. A hook 68 is formed at one end of the strip 70, and a handle 72 made of wood or other thermal insulating material is provided at the other end of the strip. A plurality of spaced apart apertures 74 extend along the length of the strip. A positioning pin 76 is secured by a cord, wire, or cable 78 to the handle 72 or another portion of the tool 66.

[0025] To adjust the lower grate 18 of the cooking assembly 10, a user extends the grasping tool 66 through the bars 22 of the upper grate 14 and manipulates the tool 66 until the hook 68 engages the central bar 60 of the lower frame 50. The user then inserts the positioning pin 76 through the aperture 74 nearest the upper grate 14, as shown in FIG. 5. When the positioning pin 76 is supported on the upper grate 14, the grasping tool 66 is locked in place relative to the upper grate 14, and the lower grate 18 is prevented from moving downwardly relative to the upper grate 14. The user can then release the locking mechanism 64 on the lower frame 50, remove the positioning pin 76 from the aperture 74, raise or lower the hook 68 to reposition the lower frame 50 and grate 18, and finally retighten the locking mechanism 64 when the lower grate 18 is in its desired position.

[0026] A cooking grate 70 according to an alternate embodiment of the disclosure is shown in FIG. 6. In this embodiment, the support frame is eliminated, and the adjustment mechanism comprises a plurality of cylindrical sleeves 72 that are integrally coupled to the perimeter 74 of the grate 70. In all other respects, the structure and operation of an outdoor cooking assembly having this type of grate 70 is identical to the structure and operation of the outdoor cooking assembly of FIGS. 1-5, except that the hook of the grasping tool is manipulated to grasp one of the horizontal bars 76 of the grate 70, rather than the central bar of a frame.

[0027] While exemplary embodiments are described above, it is not intended that these embodiments describe all possible forms of the invention. Rather, the words used in the specification are words of description rather than limitation, and it is understood that various changes may be made without departing from the spirit and scope of the invention. Additionally, the features of various implementing embodiments may be combined to form further embodiments of the invention.
