         9 . A rotisserie device according to  claim 8 , wherein the flanged ring and the tapered height cover supporting portion each have upper surfaces, and at a 6 o'clock position such upper surfaces are at the same height with respect to one another as measured from the base sealing surface. 
     
     
         10 . A rotisserie device according to  claim 3  wherein the flanged ring at least partially shields the base sealing surface from grilling heat, and discourages inflow or outflow of air proximate the hinge. 
     
     
         11 . A rotisserie device according to  claim 3  wherein the flanged ring has a flanged ring thickness, and a ring height 4 to 20 times the flanged ring thickness. 
     
     
         12 . A rotisserie device according to  claim 3  wherein the flanged ring helps locate and retain the support ring with respect to the grill base and cover. 
     
     
         13 . A rotisserie device according to  claim 3  wherein the flanged ring improves the structural integrity of the support ring if the support ring is subjected to sudden temperature change or is accidentally dropped. 
     
     
         14 . A rotisserie device according to  claim 3  wherein the flanged ring and support ring are a unitary object made of cast aluminum. 
     
     
         15 . A rotisserie device according to  claim 1  wherein the wedge-shaped side profile enables a cook to close and seal the grill cover in a partially opened position when grilling using the device.
