Heat source 14 comprises a container holding a combustible fuel such as a Sterno Brand™ heat source including a flammable mixture of 3.3% methyl alcohol, available from Candle Corp. of America of Des Plaines, Ill. Alternatively, other heat sources, such as electric heating elements or containers containing other combustible fuels may be used. According the example shown,heat source 14 is cylindrically shaped. Alternatively, other geometries may be used. Whenheat source 14 is used to produce heat, water inwater pan 16 distributes that heat about the bottom surface offood pan 18 to raise or maintain the temperature of the contents offood pan 18. -
Water pan 16 includes abottom 26,elongated sidewalls 28 andshorter sidewalls 30 extending frombottom 26, and arim 32 extending fromelongated sidewalls 28 andshorter sidewalls 30.

Alternatively,side members 46 may be solid to provide greater strength. Also, whileside members 46 are shown as round tubes, other geometries including, but not limited to, oval, rectangular, and polygonal geometries may be used. -
Chafer system 10 can be easily assembled from relatively few parts, and without the use of welding or other complicated manufacturing techniques.Handles 44 are coupled toside members 46 to form aframe 24 that is configured to extend aboutwater pan 16.Handles 44 includeprotrusions 58 that extend intoaxial recesses 56 inside members 46.Fasteners 60 secure ends 42 ofsupports 22 to frame 24, andprotrusions 58 ofhandles 44 toside members 46. -
FIGS. 4 and 5 illustrate the connections betweenhandle 44 andside member 46, and betweensupport 22 andframe 24 in greater detail.FIGS. 4 and 5 show side member 46, handle 44,support 22, andfastener 60. As shown byFIGS. 4 and 5 ,side member 46 is provided with anaxial recess 56 whilehandle 44 is provided with aprotrusion 58.Axial recess 56 receivesprotrusion 58 ofhandle 44. Alternatively, handle 44 could be provided with a recess for receiving a portion of a side member. Further, whileprotrusion 58 is shown as hollow, the protrusion may be solid. Also, whileaxial recess 56 andprotrusion 58 are shown as cylindrical, other geometries including, but not limited to, oval, rectangular, and polygonal could be used. - As further shown in
FIG. 4 ,support 22 is coupled to frame 24 by partially encircling the circumferences of both handle 44 andside member 46 by approximately 315 degrees withend 42. This configuration makes it possible to securely connect supports 22 to frame 24 without the use of welding or other more costly methods of manufacture. Ends 42 of the support may be pre-shaped by wrapping the ends about a mandrel or similar device so that the end is configured to slide over a portion of the frame. Alternatively, ends 42 ofsupports 22 may be wrapped directly aboutframe 24. Further, end 42 may only encircle a portion ofhandle 44 or a portion ofside member 46. Also, end 42 may encircle more or less of the circumference offrame 24 sufficient to couplesupport 22 to frame 24. - To further
secure handle 44,side member 46 andsupport 22 to one another,rack 12 additionally includesfasteners 60. As shown inFIGS. 4 and 5 , each offastener 60 extends throughend 42,side member 46, andprotrusion 58 to securehandle 44 toside member 46, andsupport 22 to frame 24. This configuration is advantageous in that only one fastener is required for joining all three parts: handle 44,side member 46, andsupport 22.Fastener 60 may be a screw, bolt, rivet or other suitable device. Coupling supports 22 to frame 24 in this way may eliminate the need for welding or other costly and complex manufacturing processes thus reducing assembly time and cost. Alternatively, separate fasteners may be used to couple handles 44 toside members 46 andsupport 22 to frame 24. According to an exemplary embodiment,fastener 60 is made of steel, however other suitable materials may be used. Also, other methods of securing handle 44 toside member 46, such as a compression fitting, may be used in place offastener 60. Alternatively,frame 24 may be provided with grooves to receive ends 42 thesupports 22 to obviate the need for fasteners. Further,side members 46 or handles 44 may be provided with at least one detent while the other ofside members 46 or handles 44 is provided with at least one biased member such as a prong or ratchet configured to engage the detent andsecure handles 44 toside members 46. - Overall,
chafer system 10 eliminates the need to use welding and other costly manufacturing techniques.Fuel holder 36 is formed as a single unitary body withsupport 22 which eliminates the need for any fasteners, welds, or other connection methods to securefuel holder 36 to support 22. This construction also eliminates the need for multipart supports. Each ofside members 46 includes anaxial recess 56 which receivesprotrusion 58 from each ofhandles 44 so thatside members 46 and handles 44form frame 24 which provides anenclosed area 49 for receivingwater pan 16.Side member 46 is further secured to handle 44 byfastener 60, which eliminates the need for welding to join these components.Frame 24 has a generally tubular construction which provides greater strength and simpler assembly than other frames constructed of wire or metal bands. Ends 42 partially encircles portions offrame 24 and is further secured to frame 24 byfastener 60. Again, no welding is required to couplesupports 22 to frame 24. Because no welding in required,Chafer system 10 may be sold or packaged as a kit that may be inexpensively shipped, and easily assembled. - Although the present invention has been described with reference to example embodiments, workers skilled in the art will recognize that changes may be made in form and detail without departing from the spirit and scope of the invention. For example, although different preferred embodiments may have been described as including one or more features providing one or more benefits, it is contemplated that the described features may be interchanged with one another or alternatively be combined with one another in the described preferred embodiments or in other alternative embodiments. Because the technology of the present invention is relatively complex, not all changes in the technology are foreseeable. The present invention described with reference to the preferred embodiments and set forth in the following claims is manifestly intended to be as broad as possible. For example, unless specifically otherwise noted, the claims reciting a single particular element also encompass a plurality of such particular elements.
