Detachable external heating device for an outdoor grill or smoker

Abstract

Disclosed is a grid-like device for the support of the bottom exterior surface of a cooking vessel, the grid being removably placed atop the upper exterior surface of an outdoor cooking grill or smoker. Three identically-shaped and symmetrically bent metal rectangular bands are conjoined at their midpoints to form essentially a spherical grid shape. A series of symmetrical bends, arcs, and rounds are formed at specific intervals transverse to the length of each band such that the cumulative shape of the adjoined bands forms the grid. The bottom-most segment of the support grid comprises legs and feet of a semi-rigid elasticity such that the support device may be flexibly placed about the top of the grill or smoker. Spring tension coils connect the inner surfaces of the bands to stabilize the grid shape and to impart leveraged gripping force upon the feet of the grid.

DETAILED DESCRIPTION OF THE INVENTION

(6) The objects, features, and advantages of the concept presented in this application are more readily understood when referring to the accompanying drawings. The drawings, totaling five figures, show the basic components and functions of embodiments and/or methods of use. In the several figures, like reference numbers are used in each figure to correspond to the same component as may be depicted in other figures.

(7) The discussion of the present inventive concept will be initiated with FIG. 1, which illustrates the support grid 1 in the configuration as a finished product which would be used by a consumer.

(8) The disclosed support grid 1 comprises three identical, primarily longitudinal, conjoined metallic bands, being a first band 5, a second band 5(a), and a third band 5(b). The three bands 5, 5(a), 5(b) are composed of a semi-rigid material, enabling a flexing of each of the bands 5, 5(a), 5(b) as may be desired by a user to. A general perspective view of the inventive concept in its intended utilization is depicted in FIG. 1. In the various drawing figures disclosed, all three bands 5(a), 5(b), 5(c) have identical components, configurations and dimensions. Therefore, these identical items for the second and third bands 5(a), 5(b) will be further distinguished by attachment of the sub-letter (a) or (b), respectively, to the components of the second and third bands 5(a), 5(b).

(9) To form the support grid 1, all three bands 5, 5(a), 5(b) are conjoined at their respective center apertures 6, 6(a). 6(b) (not visible in FIG. 1) by any of a variety of fastening means. In the preferred embodiment, a bolt 7, a corresponding lock washer 8, and nut 9 (collectively shown in FIG. 5) are used to conjointly fasten each of the three bands 5, 5(a), 5(b) through their respective apertures 6, 6(a), 6(b) located at the midpoint of each band 5, 5(a), 5(b). By viewing FIG. 1, it can be seen that a systematic and symmetrical bending of the three bands 5, 5(a), 5(b) results in the formation of six relatively vertical legs culminating in six diametrically opposed boots 41-42, 41(a)-42(a), and 41(b)-42(b).

(10) The fastening means is tightened securely, yet still allowing restricted freedom of rotation of the three bands 5, 5(a), 5(b) about the axis of the bolt 7. The support grid 1, in its intended use, is most stable and effective by a user symmetrically spreading the three bands 5, 5(a), and 5(b) radially with respect to the axis of the bolt 7. In this manner, each of the bands 5, 5(a), 5(b) is oriented, from one to the other, by a separation angle of approximately sixty (60) degrees. This enables the six relatively horizontally opposed boots 41-42, 41(a)-42(a), and 41(b)-42(b) of each of the three bands 5, 5(a), and 5(b) to be placed atop a cooking grill or smoker in a stable and laterally balanced manner.

(11) For better clarification of the profile and configuration of each of the three bands 5, 5(a), 5(b), a profile view of the first band 5 is shown in FIG. 2. The profile of the first band 5 is identical to the profiles of the second and third bands 5(a), 5(b). In FIG. 2 there is shown a sequence of varying bends, arcs, and rounds (50-59) made orthogonally transverse to the first band 5, which all emanate from, or transform into, linear sections (30-40) of the first band 5. As can be seen, the first band 5 is symmetrical with respect to the left side in comparison to right side of the first band 5.

(12) In the preferred embodiment, the general dimensions of each band 5, 5(a), and 5(b) prior to the symmetrical transverse bending along the length of the bands 5, 5(a), 5(b), comprise 25.0 inches in length, 1.0 inch in width, and 0.125 inch thick. The boots 41-42, 41(a)-42(a), and 41(b)-42(b) are approximately 1.00 to 1.25 inch in length. These dimensions may be varied in accordance with the type and size of outdoor grill or smoker upon which the support grid 1 will be affixed. When each band 5, 5(a), 5(b) has undergone the symmetrical bending, the resulting support grid 1 has general dimensions of 9.25 inches from left to right and 6.25 inches from top to bottom. The symmetrical bending of the bands 5, 5(a), 5(b) thereby forms an inner surface 27 of each band composing the support grid 1.

(13) Again referring to FIG. 2, a description of the first band 5 will be conducted in a clockwise manner, initiated at the bottom left section of the first band 5. A horizontally-oriented segment, termed the “left foot” 30 is the starting point. Continuing to the left of the left foot 30, an arcuate, ninety-degree bend forms a “left heel” 50 of the band 5, which then transcends upwardly to form a relatively straight segment comprising a “left leg” 31 of the band 5. From this point, proceeding upward, a slight bend, termed a “left mid-bend” 51 of approximately ten degrees occurs, which then transforms into a linear segment termed a “left incline” 32.

(14) Next, in FIG. 2, there appears an arcuate bend of approximately eighty degrees, entitled a “left inward arc” 52 which transforms into a horizontal “left flat” 33 section, measuring approximately 1.0 inch in the preferred embodiment. Immediately after the left flat 33 occurs a “left outer round” 53, comprising a ninety degree bend, and forming a vertical segment, termed a “left brace” 34. Following the left brace 34 is a “left inner round” 54 of ninety degrees resulting in a horizontal segment referred to as a “top surface” 35.

(15) The top surface 35 features a center aperture 6 (integral to all three bands 5, 5(a), 5(b)), through which a type of fastener may be inserted to join all three bands at a common point. The preferred means of fastening comprises a bolt 7, fastened by a corresponding lock washer 7 and nut 9 (all shown in FIG. 5). The top surface 35 extends rightward and the bends and linear segments previously described occur in the reverse order on the right side of the center aperture 6. From the center aperture 6, the sequential description of the first band 5 continues clockwise, with a right inner round 55, a right brace 36, a right outer round 56, a right flat 37, a right inward arc 57, a right incline 38, a right mid-bend 58, a right leg 39, a right heel 59, and a right foot 40.

(16) It is to be noted that the left foot 30 and the right foot 40 are respectively covered by a boot 41 and 42, respectively. During the manufacturing process, the boots 41, 42 are constructed of elastomeric material. This elastomeric material is formed from a process comprising a coating of a plastic dip-type substance which securely adheres to each foot 30, 40 for a length of approximately 1.0 inch of each foot 30, 40.

(17) Further details essential in the description of the first band 5, include a left side aperture 25, drilled through the left incline 32, and a right side aperture 26 drilled through the right incline 38. Each of these apertures 25, 26 on opposite sides of the band 5 serve to facilitate the fastening of a rigid left tab 18 and a rigid right tab 22 (shown in FIG. 3 and FIG. 4) to the respective inner surfaces 27 of the left and right inclines 32, 38. In viewing FIG. 4, there is illustrated a depiction of a tab 18, 22 (typical of either a left or right tab 18, 22). The tab 18, 22 is attached to the inner surface 27 of the directly opposed left and right inclines 32, 38, respectively, of each of the bands 5, 5(a), 5(b).

(18) Both the left and/or right tab 18, 22 are identical to each other and comprise essentially an oblong, rigid structure bent at an angle of approximately forty-five degrees. Each tab 18, 22 is further shown having a circular opening 17, 21 in the upper section of each tab 18, 22 and an oval opening 19, 23 in the lower section of the tab 18, 22. A threaded fastener may be used to securely attach each tab 18, 22 to the respective left and right inclines 32, 38 of the first band 5. This is done by insertion of the fastener through the left side aperture 25 and into the left circular hole 17 of the left tab 18. Likewise, the fastener is inserted through the right side aperture 26 and right circular hole 21 of the right tab 22. In the preferred embodiment, the fastener comprises a rivet 24(a) integral to the left/right incline 32, 38 and co-axial with the respective left- and right-side apertures 25, 26.

(19) Reference is made to FIG. 3, which depicts the second band 5(a) in its final stage of manufacture/assembly. Two tabs 18(a), 22(a) are secured in place onto their respective left and/or right incline 32(a), 38(a). Shown are a first tension coil spring 15(a), a center closed junction ring 11, and a second tension coil spring 16(a) are linearly joined to provide a linear, tensioned connection of the left tab 18(a) to the right tab 22(a).

(20) Further details of FIG. 3 show that the first tension coil spring 15(a) culminates with a coil inner hook 14 on one end and a coil outer hook 13 on the opposite end. Also shown is an identical second tension coil spring 16(a) with its coil inner hook 14 and a coil outer hook 13. The center closed junction ring 11, which is essentially a closed circular ring, serves as a common connecting point for the inner hook 14 of the first tension coil spring 15(a) and the inner hook 14 of the second tension coil spring 16(a). The outer hook 13 of the first tension coil spring 15(a) and the outer hook 13 of the second tension coil spring 16(a) are connected to the respective left tab 18(a) and right tab 22(a), thereby providing a spring-loaded connection of the left incline 32(a) of the second band 5(a) to its right incline 38(a). In an identical manner, the left side and right side of the first band 5 and the third band 5(b) are provided with the exact spring-loaded connection arrangement.

(21) The accumulative effect of the aligned pairs of tension coil springs 15-16, 15(a)-16(a), and 15(b)-16(b) provide a leveraged, inward-directed force downward to the boots 41-42, 41(a)-42(a), and 41(b)-42(b) of the support grid 1. Therefore, there is a stabilized, friction-enhanced gripping force for the support grid 1 against the generally rounded exterior of an outdoor grill or smoker.

(22) In the preferred embodiment, each band 5, 5(a), 5(b), prior to the bending process, comprises dimensions of approximately 25.0 inches in length, 1.0 inches in width, and 0.125 inch in thickness. The dimensions of the bands 5, 5(a), 5(b) may vary in accordance with the physical characteristics of the particular material used to fabricate the bands 5, 5(a), 5(b). The support grid 1 itself is formed by the permanent fastening of the first band 5, the second band 5(a), and the third band 5b) to each other at overlapping positions corresponding to the center aperture 6 in the top side 35, 35(a), 35(b) of each respective band 5, 5(a), 5(b).
