Abstract
ABSTRACT
The tubular frame of the grill cart forms a laterally extending shelf with opening into which an insulated container removably nests. A
heat shield of folded metal with slotted apertures to inhibit heat transfer by conduction protects the container from the intense heat developed by the grill by deflecting radiated thermal energy and by inhibiting air current convection heat transfer. The insulated container may hold either refrigerated or heated items and features opposing carrying handles which rest upon the frame to support the container with its lid in a generally horizontal plane. The lid in this position may be used as a countertop work space while tending the grill. The lid may also be flipped over to expose a contoured surface with recess compartments for holding beverage containers, plates and trays.

GAS GRIIL ~OOLER ST{~F
Background and Summary of the Invention The invention relates generally to barbecue grills and more particularlv to a barbecue grill having a removable insulated container with lid formung a horizontal shelf adjacent the grill. The insulated container i9 suitable for use as a cooler and is protected bv a heat shield suPported bv the leg framework structure.
In the hot summer months barbecuing meals and eating out of doors is a popular way to entertain, to en~cy nature and to avoid the heat of a hot kitchen. Earbecue grills for this purpose can take a wide variety of shapes, sizes and configurations, ranging from small charcoal fired hibachi grills to multiple kurner gas or propane fired grills mounted upon carts having shelves for convenience. At the tvpical patio cookout or picnic one often also finds the ubiquitous cooler for containing cold beverages, ice and other condiments and foods requiring refrigeration, ~ hile a suita~le grill, a cooler, perhaps a few lawn chairs and the friends or family can offer the makings of a good barbecue or picnic, there i8 still considerable room for improvement in the grill and cooler art. m e present invention offers such an improvement by providing the convenience of a grill having a removable insulated container or cooler which integrally nests in side extensions of the cart. m e container is preferably a double-walled and insulated plastic container having a removable and invertible cover which defines a substantially horizontal shelf adjacent the grill for the convenient placement of cooking utensils an~ the like while oooking. The container or oooler i8 removably carried by or attached to the grill cart in close proximity to the grill itself.

.
A heat shield protects the container or cooler from the intense heat of the grill heat source. The open top of the container or cooler is formed with laterally extending handles which rest atop the side extending tubular frame of the cart to hold the container in place, allowing the body of the container to extend through and beneath and side extending frame.
The heat shield comprises a rebent or folded sheet metal structure defining two panels interposed between the grill housing and the insulted container. The folded shield defines an airspace between the panels and is further formed with a plurality of elongated slotted openings at the fold. The slotted openings minimize heat transfer by conduction from one panel to the other.
In summary, therefore, the present invention may be considered as providing a grill and storage apparatus which comprises: a grill having a containment means for containing at least one heat source; at least one insulated container; an external frame for receiving and supporting the grill; and a heat shield for protecting the insulated container from heat developed by the heat source. The frame has an outward and laterally extending support portion which defines an opening, the support portion further being substantially thermally isolated from the containment means. The insulated container is removably supported by the support portion and nestably engages the opening. The heat shield, as indicated, comprises a rebent sheet member disposed in spaced relation betw~en the containment means and the insulated container.
Thus the invention provides the convenience and utility of both a grill and an insulated contair.er or cooler in a single package, with the lid of the insulated container serving as a horizontal shelf adjacent the grill. The mechanism for holding the insulated container in place also serves as handles for carrying the insulated container when it is separated from the grill unit. For a more complete understanding of the invention, its objects and advantages, reference may be had to the following specification and to the accompanying drawings.

Figure 5 is a cross-sectional view of the insulated container;
and Figure 6 is a detailed cross-sectional view showing the manner in which the container trim member snap fits in place.
Description of the Preferred Embcdiment Referring to Figure 1, the grill and container apparatus is illustrated generally at 10. The apparatus includes a frame 12, preferably constructed of hollow tubular metal stock of rectangular cross section. Frame 12 may be in the form of a cart having wheels or casters (not shcwn) and it may include one or more storage racks for holding fuel cannisters and may be outfitted with front, rear and side panels to define an enclosed lower cabinet and to give the apparatus a re decorative appearance. Tb s1mplify the understanding of the invention, the lower shelf, fuel cannister and panels have not been illustrated in the Figures.
Frame 12 defines twn pairs of generally vertically arranged legs 14, each pair being connected at the tcp to form an outwardly and laterally extending support portion 16. Support portions 16 may serve as handles when transporting the apparatus 10 and also define a generally rectangular opening 18 into which the insulated container 20 nests.
. .
. .
. :
Mbre specifically, container 20 has a lower portion 22 which e~tends through opening 18 and depends generally below support portion 16.
Container 20 further has an outwardl~ flared open end 24. The underside of flared open end 24 rests upon support portion 16. Preferably the flared open end includes a pair of out~ardly extendinq and opposing handle portions 26. Container 20 also includes a lid 28. Lid 28 is reversible in that it has a substantially flat first surface 30, which serves as a convenient countertop. As seen in Figure 2, the flip side of lid 28 has a molded contoured surface 32 having a plurality of recessed comparbments 34 of various shapes for holding beverage containers, plates, trays and the like. Figure 2 also illustrates container 20 lifted away from nesting engagement in rectangular opening 18. As illustrated, lower portion 22 is of a size and shape to generally conform to the size and shape of opening 18.
The grill and container apparatus further co~prises grill unit 36 which includes a lcwer grill housing 38 and an uPper hood or cover 40. Disposed within the lower housing is a heat source such as gas burner 44 (Figure 2). ~hile a gas burner of the type for bNrning bcttled gas is presently preferred, the invention may be practiced using grills employing other heat sources, inclu~ing natural gas fed burners, liquid fossil fuels and charcoal or wood, to name a few.
Tb protect container 20 from the intense heat given off by burner 44 during operation, a heat shield 46 is provided in the location ~hcwn in Figures 1 and 2 generally between lcwer grill housing 38 and container 20 when nested in rectangular opening 18. Althaugh only one container has been illustrated in Figures 1 and 2 for placement within cpening 18 on the right-hand side of apparatus 10, it will be understood : that a s~milar oontainer may be placed in the opening 18 on the left-hand ~ , .
. ' ' - ~ ~
side of the apparatus as well. Preferably both containers are of the same size and shape so that thev may be interchangeably placed in either of the openings 18.
Figures 3 and 4 show heat shield 46 in greater detail.
Preferably heat shield 46 comprises a rebent or folded rectangular sheet metal member folded as at 48 to define a generally rectangular grill facing panel 50 and a complementary container facin~ panel 52 and a mounting panel 51. Panels 50 and 52 define an airspace 54 therebetween and the shield is formed with a plurality of elongated slotted openings 56 along folds 48. Thus except for a few sheet metal bridge portions 58 which hold panels 50, 51 and 52 together, the panels are otherwise detached from one another, thereby minimizing heat transfer from panel 50 to panel 51 and from panel 51 to panel 52 by thermal conduction. mus the slotted openings 56 provide a means for minimizing thermal conduction between panels 50 and 52. While the slotted opening is presentlv preferred, other alternative means for minimizing thermal conduction are also possible, including formlng the folded portion or bridge portion from a material of low thermal conductivity such as plastic, w~od or the like.
In addition, airspace 54 may be filled with a thermally insulating material such as fiberglass, or the like. Heat shield 46 operates as a barrier, reducing heat transfer by air current convection and also reduce heat transfer by deflecting radiant energy away from container 20.
Referring now to Figure 5, the presently preferred co~tainer 20 comprises a double~walled lower portion 22 in which an outer double w~ forming shell 60 encloses an insulating material 62. Lcwer portion 22 is open at the top as at 64 and includes a plastic trim n~mber 66 as shown in Figure 6, trim member 66 snap fits onto shell 60 as at 68. m e trim member defines an airspace 70 which sen~es as further - . : . - , -.
,' -:
insulation abcut the open end. The trim member define~ a smooth generallv~ertically arranged sidewall 7~ into which the lid (not shown) nests.
Trim member 66 further defines a radially extendin~ channel 74. ~hen lid 28 is positioned in place, as shown in Figures 1 and 2, the channel 74 serves to permit the user to grasp and remove the lid bY grasping rail 76 (on the flat surface side) or by grasping raised platform 78 (on contoured side). m e flat vertical sidewalls 72 provide a close tolerance, tight fit with lid 28, thereb~ improving the insul~ting qualities of the contaLner.
As illustrated in Figure 4, trim member 66 is positioned so that only it and not the lower portion 22 contacts the heat shield. Contact is generally along the upper partion of the panel 52. The trim member is preferably made of a heat resistant Plastic material such as ~lass-filled polypropylene.
The container is preferably of a plastic material such as vinyl, polvethylene or the like, but it may be made of other materials as well.
m e contamer may be used to store either refrigeratea items which are desired to be kept cold or it mav store heated items, such as food prepared on the grill prior to serving. Container 20 may be placed directly in a refrigerator or freezer prior to use and then placed in nesting relationship within opening 18 for use.
While the invention has been described in connection with the presently preferred embod1ment, ~t will be understnod that the invention is capable of certain modification and change wlthout departin~ from the 6pirit of the invention as set forth in the appended claims.
