Outdoor cookers or stoves are a popular way to prepare food away from the kitchen of a home. Conventionally, outdoor cookers or stoves include an open support over a heat source such as a collection of charcoal briquettes or one or more gas burners. The open support, or grill, is commonly constructed of a number of horizontally disposed, parallel elements connected to a frame. The elements of the grill are most often fashioned of relatively thin, cylindrical metal. The diameter of the cylindrical stock material is often substantially smaller than the spacing between cylindrical elements, leaving a fairly open structure upon which the food to be grilled may be placed.
A grilling surface as described above may be sufficient for cooking large foodstuffs or for cooking pieces of food which tend to stay whole during the cooking process. However, the described cooking surface may not be adequate for cooking smaller pieces of food, or for cooking food which flakes apart or breaks into smaller pieces during the cooking process; these smaller pieces of food may easily fall through the cooking surface and be lost to the person doing the cooking. Having to handle and/or turn the food during the cooking process may only exacerbate these problems.
Other grilling assemblies have been described in the prior art which serve to overcome some of the above-described problems. However, earlier grilling assemblies have various shortcomings, including: being made of fine-gauge wire mesh; having integral covers; having handles which are unstable or difficult to utilize; and not providing an enclosed space for containing the food items.
The grill assembly described in the present disclosure overcomes the flaws inherent in the prior art by providing an enclosure which may be used for cooking food of many types while enhancing ease of use and providing a robust design.
Type Here
Each handle 12 may include a grip 16 and a rod 18. Grip 16 may be shaped in an elongated manner such that it has a proximal end 20 near to the main grill body 14 and a distal end 22 remote from the main grill body 14. In the depicted embodiment, grip 16 has an elongated shape, making it easily grasped by a person's hand, but it may be designed in any shape suitable for holding, without departing from the spirit of the present disclosure. Grip 16 may be made of any suitable material for being grasped by a human hand. For example, material for grip 16 may include, but is not limited to wood, a suitable metal (such as steel), plastic, rubber, silicone, etc. It is preferable that the materials not be conductive to heat or that the configuration of the grip be such that heat is easily dissipated. For example, the handle may be constructed of an open, rigid metallic coil.
Grip 16 may include, near its distal end 22, one or more holes 24 which may be used for attaching a lanyard 26. Holes 24 may be any suitable shape for holding lanyard 26. Lanyard 26 may be used as a support for hanging the removable handles 12 on, for example, a storage hook when they are not in use. Therefore, lanyard 26 may be made of any suitable material that will allow it to perform this function, such as leather, twine, plastic, metal, rubber, nylon, etc.
Grip 16 is normally non-removably attached to a rod 18. Alternatively, the handle could be designed such that the grip and rod are removably attached to each other. Rod 18 may be made of any material suitable for the task of being removably inserted into, and supporting, main grill body 14, such as metal, wood, rubber, plastic, etc. In a preferred embodiment, the design of rod 18 may include one or more protrusions 28 and a rod groove 40 (best seen in
Protrusions 28 (see
As shown in
Top grill member 30 and bottom grill member 32 of main grill body 14 may include engagement surfaces 46 at their peripheries, such that the top and bottom grill members and their associated engagement surfaces define a central enclosure identified at 48. The limits of the central enclosure may be roughly defined as the space bounded by the four corners, in this embodiment, of the top grill member 30 and bottom grill member 32, as shown by dashed lines 50 in
As is clear from the figures, top grill member 30 and bottom grill member 32 may be constructed so that they have an open grillwork surface, composed of grill slats 52 and grill openings 54. The combination of grill slats 52 and grill openings 54, and their relative sizes, makes it possible to place food in the central enclosure of the grill assembly, and cook it, without the food exiting the container. The relative sizes, spacing, and placement of the grill slats and openings, as shown in the figures, also serve the functional role of preventing the main grill body 14 from warping under conditions of extreme heating. The absence of appreciable warping of the main grill body, even when it is hot, allows the grill assembly to be easily opened and closed before, during, and after the cooking process.
Although insertion bodies 34 and insertion openings 44 may be designed as having any one of many different shapes and sizes, in a preferred embodiment they are designed in such a way that they may removably and rotatably receive rod 18 of handle 12. For example, if rod 18 of handle 12 has a circular cross-sectional area of a given size, then it may be preferable for insertion body 34 and insertion opening 44 to have circular cross-sectional areas of a similar size. In a preferred embodiment, rods 18 may be cylindrical in shape, insertion bodies 34 may be tubular in shape, and insertion openings 44 may be circular in shape. When designed with common cross-sectional shapes and sizes, rod 18, insertion body 34 and insertion opening 44 may be removably slid together along insertion axis 42, such that rod 18 of handle 12 resides closely within insertion body 34 and insertion opening 44.
To hold food items in the main grill body, and to prevent opening of the grill assembly when it is moved to or from the cooking surface and/or turned on the cooking surface, it may be preferable to include engagement mechanisms which serve to removably fasten the individual grill members of the main grill body into a useful whole. A preferred embodiment of the present disclosure may typically include two discrete engagement mechanisms: removable handles placed into insertion bodies and insertion openings, and engagement members placed into engagement openings.
Insertion of handles 12 into the closed main grill body 14 may serve to couple the top and bottom grill members together at a first position. Insertion of handle 12 causes rod 18 of the handle to enter insertion body 34 and the insertion opening. Upon full insertion of rod 18, which may be determined by the placement of protrusions 28 along its length, the tip 36 of the rod may impinge upon the central enclosure 48. In so doing, the tip 36 of rod 18 may necessarily traverse the engagement surfaces 46 of both the top grill member 30 and the bottom grill member 32. By traversing an engagement surface of each of the top and bottom grill members of the main grill body, handles 12 serve to restrict relative movement between the two pieces at a first position.
As depicted in
A brief description of the use of a grill assembly designed according to the details of the present disclosure will illuminate how the various parts of the present disclosure come together into a usable whole. The description will refer, for the most part, to various features shown in
Beginning with an empty grill assembly, a user may find it in a closed configuration with handles 12 inserted into insertion bodies 34 and insertion openings 44, and engagement members 60 within engagement openings 62, as shown in the solid line depiction of
Opening the main grill body is facilitated by using one or both handles to lift the top grill member off the bottom grill member. The rods 18 of handles 12 may be designed to fit into any of the grill openings 54, such that inserting the rods into the openings will allow that grill member to be moved in a direction of the user's choosing. In the embodiment of the present disclosure, the grill member which is moved may need to be moved at an angle; the presence of the second engagement mechanism (preferably including the engagement members and their associated openings) may inhibit direct upward movement of the moved grill member of the main grill body. Moving the grill member by rotating it to an open angle will allow the engagement members 60 to release from the engagement openings 62 in such a way that the two grill members of the main grill body may be completely separated. With the two grill members of the main grill body separated, the food items to be cooked are easily positioned within the central enclosure.
Reversing the above-described opening procedure allows the two grill members of the main grill body to be securely and removably fastened together. Using one or more of the handles to manipulate the positioning of the pieces, the top grill member of the main grill body is placed at an angle relative to the bottom grill member, and the engagement members 60 and engagement openings 62 are placed opposed to each other. Rotating the top grill member 30 down toward the bottom grill member 32 causes insertion of the engagement members into the engagement openings, and simultaneously brings the insertion bodies 34 and their associated insertion openings 44 into close proximity. Finally, inserting the handles 12 into the insertion bodies and through the insertion openings finalizes the engagement process. The two grill members of the main grill body are now securely (but removably) fastened together for use. In the case where insertion openings 44 and engagement openings 62 are of comparable size and placed symmetrically on opposite ends of the top grill member 30, as present in the preferred embodiment of the present disclosure, then top grill member 30 may be reversibly installed relative to bottom grill member 32. This arrangement may be noted when comparing
There are other useful characteristics which follow from the grill assembly design described in the present disclosure. One advantage of the depicted embodiment is that the handles, being made is such a way that they are removably inserted into the main grill body, may be removed during the cooking process after the main grill body has been placed upon the cooker. For example, placing the grill assembly in a cooker that has a cover which may be opened and/or closed might inhibit movement of the cover if the handles are present in the insertion bodies. However, removing the handles of the grill assembly after placing the main grill body in the cooker may allow the cover of the cooker to be freely closed and may allow all the generated heat to be maintained within the cooker, speeding the cooking process.
A second benefit of the preferred embodiment of the present disclosure involves the safety of the user. Because the handles of the preferred embodiment are removable, they may be outside of or away from the cooker during the cooking process and may stay cool to the touch. Cool handles may be safer for the user and may obviate the need for the user to grasp them with hot pads or while wearing a heat-resistant hand covering, before moving the grill assembly from one position to another. Avoiding the use of hot pads or hand coverings, on the part of the user, also facilitates the ease of use of the grill assembly and may also make accidents less likely to occur.
Another benefit of the design of the preferred embodiment is the ease with which the grill assembly may be turned over. In order for efficient heating of both sides of a food item to occur, it may be desirable to turn the food partway through the cooking process. Since the grill assembly may sit stably with either of its halves contacting the cooking surface, it is a simple matter to turn the grill assembly over while the food is contained within the central enclosure, instead of opening the main grill body and turning over the food. In addition, the design of the rods of the handles in the present disclosure presents a distinct advantage for turning over the grill assembly. As was noted earlier, in a preferred embodiment of the present disclosure, the rods of the handles, and the insertion bodies and openings into which they insert, may all have circular cross-sectional areas of similar sizes. This means that the handles may rotate freely within the attachment bodies while still performing the function of removably engaging the grill members. If the two handles are grasped in the hands of a user, turning over the grill assembly may be performed without the user needing to either release the handles or alter the user's handhold. This feature may prevent a user from performing a movement which might cause biomechanical strain (such as a user rotating their wrists while holding a heavy object in their hands).
Because the two handles form a stable gripping platform, and because the handles rotate freely in the attachment bodies while still engaging the two halves of the main grill body, turning food by turning over the entire grill assembly becomes an easy, controlled exercise. Due to the design of the preferred embodiment of the present disclosure, it is also possible to turn the grill assembly with one handle only and still maintain the removable engagement of the grill members. For example, a user may insert one handle into the grill assembly and rotate the assembly with another implement that is not the second handle. The second implement may be a spatula, a knife, a fork, or some other appropriate tool.
A further benefit of the design of the preferred embodiment relates to the ability of the grill assembly to maintain its functionality when it is heated. Grill openings 54 may be disposed along the peripheries of the top grill member 30 and bottom grill member 32 to prevent warping of the grill assembly under extremes of heat exposure. Placing grill openings 54 so that they are near, and parallel to, the peripheries of the top and bottom grill members may allow for the center sections of the top and bottom grill members to be structurally isolated from the peripheries of the grill members. This further may allow for heat-induced expansion of the center sections of the top and bottom grill members to occur without causing binding of the top and bottom grill members. Although the described embodiment shows grill openings oriented perpendicular to other grill openings, it is understood that other dispositions of the grill openings may be possible in different applications without departing from the spirit of the present disclosure.
A similar prevention of heat-induced expansion and binding may be obtained by using an alternative construction of the center section of the top grill member 30 and bottom grill member 32.
Although the present invention has been shown and described with reference to the foregoing operational principles and preferred embodiments, it will be apparent to those skilled in the art that various changes in form and detail may be made without departing from the spirit and scope of the invention. The present invention is intended to embrace all such alternatives, modifications and variances that fall within the scope of the appended claims.
