Description
Background of the Invention
[0002] This invention relates generally to outdoor lighting devices and, more particularly, to a gas powered barbecue grill lighting apparatus.
[0003] The use of outdoor cooking grills has become very popular and such grills are often used for cooking an evening meal. The use of outdoor grills during the evening often results in an inadequate amount of ambient light being available to discern when the meat has been completely cooked. Various devices have been proposed in the prior art for lighting a grill, such as those disclosed in U.S. Pat. Nos. 3,992,618 to Matthews, U.S. Pat. No. 5,257,169 to Walendziak, and U.S. Pat. No. 5,664,875 to Hegedus. Although assumably effective for their particular purposes, they are not as suitable for use with new or existing outdoor gas grills as the invention disclosed herein.
[0004] Therefore, it is desirable to have a grill lighting device that is easily installed on new or existing gas grills. It is further desirable to have an apparatus which can be powered by the same combustible fuel that operates the gas grill. Finally, it is desirable to have a lighting apparatus which is pivotal so as to selectably light the grill cooking grate or an area adjacent to the grill.
Summary of the Invention
[0005] A grill lighting apparatus according to a preferred embodiment of the present invention includes a hollow conduit having a rectangular circumference as is customary for portable grill frame members. The conduit has a first end portion mounted to a horizontally disposed hollow frame member of an outdoor gas grill, such as an arm supporting a side platform of the grill. The conduit further includes a second end portion parallel to and spaced apart from the first end portion by an intermediate portion extending upwardly therebetween.
[0006] An illumination assembly is pivotally coupled to the second end portion such that it can be positioned to illuminate the cooking grate of the grill or an area adjacent to the grill. A hose having first and second ends extends through the hollow interior of the intermediate and second end portions of the conduit. The first end of the hose may be connected to a container of combustible fuel, such as propane gas, that is also used to fuel the cooking means of the grill. The second end of the hose is coupled to the illumination assembly for supplying fuel thereto. The illumination assembly further includes a mantle and igniter for selectably providing light during operation thereof.
[0007] Therefore, it is a general object of this invention to provide a lighting apparatus which can be used with a gas grill for illuminating food cooking on a cooking grate thereof.
[0008] Another object of this invention is to provide a lighting apparatus, as aforesaid, which is easy to install on new and existing portable gas grills.
[0009] Still another object of this invention is to provide a lighting apparatus, as aforesaid, which is economical to manufacture.
[0010] Yet another object of this invention is to provide a lighting apparatus, as aforesaid, which includes an illumination assembly operated with the same combustible fuel used to operate the grill.
[0011] A further object of this invention is to provide a lighting apparatus, as aforesaid, in which the illumination assembly is pivotal so as to direct light upon the cooking grate or an area adjacent the grill.
[0012] A still further object of this invention is to provide a lighting apparatus, as aforesaid, in which the illumination assembly may be operated from the main control panel of the grill.
[0013] Other objects and advantages of this invention will become apparent from the following description taken in connection with the accompanying drawings, wherein is set forth by way of illustration and example, an embodiment of this invention.

Description of the Preferred Embodiment
[0021] The preferred embodiment of the grill lighting device will now be described with reference to FIGS. 1-4bof the accompanying drawings. The lighting apparatus 10 is particularly constructed to be used in conjunction with a conventional portable outdoor gas grill 20 having a frame assembly 22 (FIGS. 1 and 2). The frame assembly 22 includes a plurality of legs 24 with cross-struts 26 therebetween and a combustible fuel container 28 mounted thereto. The fuel container 28 contains propane or other suitable gas. A cooking grate 30 is supported atop the legs 24 and at least one side platform 32 is mounted atop horizontal support arms 34 with fasteners 36 such as bolt/nut combinations. The support legs 24 and arms 34 conventionally found on portable grills present a rectangular circumference although grills with tubular support members can also be used with this invention.
[0022] The lighting apparatus 10 includes an elongate conduit 40 having a peripherally rectangular circumference of the type that is conventional for the construction of outdoor cooking grills. It is understood, however, that the conduit 40 may be constructed of tubular conduit where it is to be used with a grill having tubular frame members. As best shown in FIGS. 4aand 4b, the lighting apparatus 10 includes a first end portion 42 having a peripheral circumference smaller than a circumference of a horizontal support arm 34 such that the first end portion 42 may be slidably received within the support arm 34 through an opening 35 in the end thereof and secured thereto with fasteners 36 such as bolt/nut combinations. Alternatively, the first end portion 42 may be mounted to a side of the support arm 34 with laterally extending fasteners 38 such as bolt/nut combinations (FIGS. 5aand 5b).
[0023] The conduit 40 includes an intermediate portion 44 extending upwardly and normal to the first end portion 42. A second end portion 48 is normal to the intermediate portion 44 and parallel to the first end portion 42. The lower end of the intermediate portion 44 includes an aperture 46. A primary segment 52 of an elongate flexible hose extends through the aperture 46 and through the intermediate 44 and second 48 conduit portions, the primary segment 52 exiting and extending beyond an open distal end 50 of the second end portion 48 of the conduit 40. An auxiliary segment 54 of the hose includes a first end 56 coupled to a valve 29 on the grill fuel container 28 and a second end 58 coupled to a lower end of the primary segment 52.
[0024] As best shown in FIG. 3, the lighting apparatus 10 further includes an illumination assembly 60 pivotally coupled to the free end 50 of the second end portion 48 of the conduit 40 with a swivel assembly 80. The swivel assembly 80 includes a first arm 82 having a first end pivotally coupled to the free end 50 of the second end portion 48 of the conduit 40 with a hinge 84. The swivel assembly 80 further includes a second arm 86 having a first end pivotally coupled to a second end of the first arm 82 with a hinge 88. A pair of hooks 90 depend from the first arm 82 for supporting and guiding a portion of the primary segment 52 of the hose.
[0025] The illumination assembly 60 includes a valve 62 mounted to a second end of the second arm 86 of the swivel assembly 80. The upper end 53 of the primary segment 52 of the hose is coupled to the valve 62, the valve including a regulatory knob 64 for controlling the rate of gas flow therethrough. A supply conduit 66 extends from the valve 62 and includes a burner 68 at a terminal end thereof, the burner 68 having an igniter 70 capable of providing a spark to ignite gas flowing from the supply conduit 66. A bag-like mantle 72 is supported above the burner 68 and is constructed of a fabric which is effective to provide light when in close proximity to a flame. The illumination assembly 60 further includes a reflector 74 having a transparent shield 76 or globe depending concentrically therefrom and surrounding the mantle 72.
[0026] In use, the lighting apparatus 10 may be mounted to a gas grill 20 at the point of manufacture or by a user to a preexisting grill. The apparatus 10 is mounted by sliding the first end portion 42 into the open end 35 of a horizontal support arm 34 of a gas grill 20 and securing it thereto with the bolt/nut fasteners 36 that are provided to hold a side platform 32 to the arm 34 (FIG. 4b). Alternatively, the first end portion 42 is mounted to a side of the support arm 34 by inserting fasteners 38 laterally through the arm 34 and first end portion 42 (FIG. 5b). The primary segment 52 of the hose is then coupled to the auxiliary segment 54. The auxiliary segment 54 is coupled to a special valve 29 which, in turn, is coupled to the combustible fuel container 28 (e.g. propane tank) such that gas may be regulated to both the cooking mechanism of the grill and to the illumination assembly.
[0027] The illumination assembly 60 may be positioned so as to direct light upon the cooking grate 30 or to another area by pivoting the swivel assembly 80. The flow of gas through the supply conduit 66 and into the area within the mantle 72 may be regulated by the valve knob 64. The gas may be ignited by a user pressing a button 21 on the main grill panel area which delivers a voltage through a wire 78 to an igniter 70 on the illumination assembly burner 68.
[0028] It is understood that while certain forms of this invention have been illustrated and described, it is not limited thereto except insofar as such limitations are included in the following claims and allowable functional equivalents thereof.
