Collapsible dual-tier fire grate kit

Abstract

A collapsible fire grate kit includes a pair of opposing support frames. A lower grate and an upper grate each include a plurality of elongated members for supporting logs. The elongated members of the lower and upper grates are removably supported on the first support frame and the second support frame. A pan disposed below the lower grate between the first support frame and the second support frame for collecting ash and for outwardly radiating heat. Each elongated member of the lower and upper grates define a pair of slots receiving the first support frame and the second support frame, respectively. The slots open downwardly and extend along the longitudinal axis with the first support frame and the second support frame extending through the slots transversely to the axis so that the lower and upper grates support the first and second support frames in upright positions.

         5 . The collapsible fire grate kit as set forth in  claim 1  wherein said first support frame and said second support frame each include a base and only contact the ground along said base, said base of said first support frame extending along a straight line and said base of said second support frame extending along a straight line. 
     
     
         6 . The collapsible fire grate kit as set forth in  claim 1  wherein said first support frame and said second support frame each include legs and only contact the ground at said legs, said legs of said first support frame spaced along a straight line and said legs of said second support frame spaced along a straight line. 
     
     
         7 . The collapsible fire grate kit as set forth in  claim 1  wherein said first support frame and said second support frame are spaced from each other along said longitudinal axes. 
     
     
         8 . The collapsible fire grate kit as set forth in  claim 1  wherein said lower bars of said first and second support frames define slots for receiving said elongated members of said lower grate and wherein said upper bars of said first and second support frames define slots for receiving said elongated members of said upper grate. 
     
     
         9 . The collapsible fire grate kit as set forth in  claim 8  wherein said slots of said elongated members of said lower grate engage said slots of said lower bars and wherein said slots of said elongated members of said upper grate engage said slots of said upper bars. 
     
     
         10 . The collapsible fire grate kit as set forth in  claim 1  wherein said lower grate includes cross members fixed to and extending transverse to said longitudinal members and said upper grate includes cross members fixed to and extending transverse to said longitudinal members. 
     
     
         11 . The collapsible fire grate kit as set forth in  claim 1  wherein said first side frame and said second side frame each include an extension extending upwardly from said upper bar for retaining logs on said upper grate. 
     
     
         12 . The collapsible fire grate kit as set forth in  claim 1  wherein said lower grate and said upper grate are concave for containing the logs. 
     
     
         13 . The collapsible fire grate kit as set forth in  claim 1  wherein said pan is slideably received between said first support frame and said second support frame. 
     
     
         14 . The collapsible fire grate kit as set forth in  claim 1  wherein said pan defines perforated knock-outs for being selectively removed to receive a gas line. 
     
     
         15 . The collapsible fire grate kit as set forth in  claim 1  wherein said first support frame and said second support frame each include legs. 
     
     
         16 . The collapsible fire grate kit as set forth in  claim 15  wherein said legs each define bottoms for supporting said first and second support frames on ground and wherein said first support frame and said second support frame each define a track spaced from said bottoms of said legs and configured to slideably receive said pan.
