DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENT

[0023] Referring now to the drawings, FIGS. 1-8 show a rotisserie support insert 11 for a round barbecue grill configured in its rotisserie mode. In the rotisserie mode, a rotisserie unit 12 is attached to the insert as more fully described below. In pizza mode, the support insert is used without the rotisserie unit as later described.

[0024] The convertible rotisserie support insert 11 is seen to have an arcuate body portion 13 which has a top side 15, a bottom side 17, and an open front end 19 that can be closed off by a front cover portion 21. The height of the arcuate body portion, which is defined by the distance between the top and bottom sides of the arcuate body, is seen to taper from a maximum height at the open front end 19 of the body portion to a minimal height at the back end 23 of the body portion. As will be later described, the back end of the arcuate body portion is the portion of the insert that is placed closest to the hinge of the barbecue lid when the insert is installed on the barbecue.

[0025] The arcuate body portion 13 is constructed having a radius that conforms to the radius of the top rim of the bowl of the commercially available barbecue grill for which the insert is designed and is suitably fabricated in two sections 13A and 13B as shown in FIG. 2 that can be joined together at the back end 23 of the body by a suitable fastener or fasteners. (Fabrication of the insert in two parts allows inserts to be shipped in smaller, more compact packages.) The arcuate body portion suitably sits on and is supported by the top rim of the grill bowl. Any means can be used to clamp the arcuate body to the bowl rim.

[0026] As shown in FIGS. 1 and 2, a rotisserie unit 12 that is used with the support insert in the rotisserie mode will typically have a spit rod 25 with meat forks 27, and a rotisserie motor 35 and rotisserie handle 37 at opposite ends of the spit rod. The rotisserie unit is attached to opposite sides of the arcuate body portion of the insert so that it operatively extends across and is supported by the arcuate body. Commercially available rotisserie units are chosen with spit rods having a length that extends beyond the outer walls 14 of the insert's arcuate body. When the rotisserie unit is installed on the rotisserie support insert and when the support insert is placed on a barbecue grill for which it was designed, the meat forks 27 and any meat or other food items on the meat forks will be positioned inside of the arcuate body over the heat source in the barbecue's grill bowl.

[0027] As further shown in FIGS. 1 and 2, the rotisserie unit is attached to the top side 15 of the arcuate body of the rotisserie support insert. This top side attachment can be achieved by first attaching the rotisserie motor to the arcuate body portion 13 via a mounting bracket 36 attached to the side of the arcuate body portion near the top of the arcuate body. The mounting bracket is seen to hold the rotisserie motor in a suitable position outside of the arcuate body portion for receiving one end of the unit's spit rod. The spit rod is then held in place on the top side 15 of the arcuate body by pivot brackets 29 that pivotally slide, snap or clamp onto the ends of the spit rods. The pivot brackets in turn are provided with at least one and suitably two downwardly projecting prongs 31 that removably fit or snap tightly into prong holes 33 in the top side of the arcuate body. The prong holes (which are suitably in the shape of slots that match flat prongs on the pivot brackets) are provided on opposed sides of the arcuate body. When a rotisserie sized for the barbecue grill is mounted to the arcuate body, the rotisserie motor 35 and rotisserie handle 37 at the two ends of the spit rod will lie outside of the arcuate body.

[0028] In this rotisserie mode, a front cover portion 21 is attached to the arcuate body portion and extends across the front opening of the arcuate body portion. The front cover can be attached to the front edges 47 of the arcuate body 13 by any suitable means, such as by using mechanical fasteners, or by configuring the ends of the cover and arcuate body so that they can wedge together. Preferably, the front cover will have an arcuate shape with a radius corresponding to the radius of arcuate body portion 13 of the rotisserie insert, thereby completing the overall circular geometry of the insert. However, it shall be understood that the front cover could be provided in other shapes so long as it provides two primary support functions. First, the front cover completes the structural encirclement of the rotisserie unit, thereby providing stable support for the rotisserie unit. Second, it provides structural means for supporting the hinged lid of the barbecue above the top side of the insert's arcuate body portion to permit air flow through the cooking chamber of the barbecue grill.

[0029] The second support functionthat of supporting the hinged lid of the barbecue grill above the top side of the insert's arcuate body portionis achieved by upwardly extending lid support structures provided on the insert's front cover 21. The lid support structures are suitably in the form of vertical support walls 41 extending outwardly from the front cover which can be bent over at the top to provide elevated horizontal seating surfaces 43 positioned on the radius of the body portion. The positioning of these seating surfaces will allow the hinged lid of the barbecue grill to rest on the seating surfaces at an angled position relative to the bowl of the barbecue grill. As shown, support walls 41 are most suitably provided at each end 44 of the front cover portion.

[0030] Removal of the front cover portion allows the hinged lid of the barbecue to drop down onto the angled top side of the arcuate body portion so that it comes to rest in a second angled use position relative to the bowl of the barbecue grill. This second use position without the front cover would be the desired configuration of the insert when in its pizza mode.

[0031] FIGS. 9-11 illustrate the insert, denoted 11A, in the pizza mode. In this use mode, the rotisserie unit 11 shown in FIGS. 1-8 is removed along with the front cover 21. What is left is the arcuate body portion that can now be used to hold the grill's hinged lid in an open position (second angled use position) with an unobstructed access opening 45 for inserting a pizza or other food item onto the grill grate of the barbecue. The presence of the access opening 45 will allow air circulation within the cooking chamber without having to create a gap between the grill's hinged lid and the top side of the arcuate body.

[0032] FIGS. 12 and 13 show the insert of the invention when deployed in the rotisserie mode (FIG. 12) and pizza mode (FIG. 13). In either mode the insert is inserted into a type of commercially available barbecue grill 51 that includes a bowl 53 for a heat source and a lid 55 which is connected to the grill bowl by a hinge (not illustrated). The hinge allows the lid to be rotated about hinge point 57 all the way up to a standing position when food items are to be placed on the grill grate (not shown) of the barbecue. When the insert of the invention is used with this hinged lid barbecue grill, the hinge lid can be closed down onto the insert, where it is propped open to a much lesser degree. The degree to which the lid is propped open will depend on the use mode as above described. In FIG. 12, the rotisserie mode, lid 55 is seen to be propped open to a first angled use position, denoted P1, relative to grill bowl 53 of the barbecue grill, whereas in FIG. 13, the pizza mode, the lid of the barbecue is seen to be propped open to a second angled use position, denoted P2, relative to the grill bowl, which is smaller than angle P1.

[0033] The degree to which lid 55 is propped open advantageously accommodates the intended use of the insert: in the rotisserie mode it provides an air gap 59 between the top side 15 of the arcuate body of the insert and the rim 61 of the hinged lid supported by the insert; in the pizza mode where the insert converts the barbecue grill into a pizza oven, the lid drops down so as to rest on the top side of the arcuate body. In this mode of use the front of the insert is now open due to the removal of front cover 21.

[0034] The above-described components of the support insert of the invention can be fabricated of bent sheet metal at relatively low cost. Suitably, the metal parts can be coated with a high heat powered coating to protect against the high heat environments in which the insert is used. Cost savings are also achieved by mounting a rotisserie to the top of the support insert in accordance with the invention as this avoids the need for more complex attachment schemes for the rotisserie taught by the prior art.

[0035] While the present invention has been described in considerable detail in the foregoing specification and accompanying drawings, it is not intended that the invention be limited to such detail, except as necessitated by the following claims. For example, it will be understood that the illustrated rotisserie unit can be attached to the arcuate body portion of the rotisserie support insert by means other than the illustrated top side attachment scheme described herein, or by other top side attachment schemes. Also, the upwardly extending lid support structures on the front cover portion of the insert can be implemented in ways other than illustrated and described, for example, by a single outwardly extending support wall centered on the front cover having a seating edge or surface for supporting the hinged lid, or by other vertical extension configurations that provide a seat for the lid of the barbecue grill.
