Grill handle with heat shield
View Patent ↗Two main embodiments of a heat shield for a barbecue grill are disclosed herein. Both are designed to reduce the transfer of heat from the heated volume of the cooking chamber to the handle of the barbecue grill. The first embodiment mounts to the exterior of the cooking chamber and is disposed between the cooking chamber and the handle. The first embodiment is contoured to interrupt the convective flow of heated air away from the handle. The second embodiment mounts to the interior of the cooking chamber opposite the handle. The second embodiment rests adjacent the inside surface of the cooking chamber to form a partially or substantially closed volume that serves as an insulating barrier for the handle.
1. A barbecue grill comprising:
a cooking chamber at least partially defined by a firebowl and a lid, the lid having an outside surface, a bottom side opening, and a generally closed top side, the lid having the general shape of a hollow spherical segment;
a handle and a heat shield positioned approximately at an apex of the lid;
the handle comprising a gripping portion and at least two leg portions, each of the two leg portions at a first end having a flange affixed adjacent to the outside surface of the lid, and the gripping portion extending between the two leg portions at a second end, whereby the gripping portion has a spaced positional relationship to the outside surface of the lid;
the heat shield affixed adjacent the outside surface of the lid and disposed between the outside surface of the lid and the gripping portion of the handle, the heat shield having a longitudinal axis which is generally aligned with a length of the gripping portion, the heat shield in a cross section plane having a generally parabolic shape with two upturned ends and a vertex that has a spaced positional relationship to the outside surface of the lid, the cross section plane being generally normal to the longitudinal axis of the heat shield, the two upturned ends being laterally spaced on opposite sides of the handle, whereby the heat shield is configured to form a heat barrier between a heated volume of the cooking chamber and the gripping portion of the handle;
the heat shield being formed from sheet metal comprising stainless steel, whereby the heat shield has a reflective surface to reduce radiation heat transfer; and,
the flange, the lid, and the heat shield each having at least one aperture which are correspondingly aligned and through which at least one fastener extends to affix the handle and the heat shield to the firebowl.
2. A barbecue grill comprising:
a cooking chamber at least partially defined by a firebowl having an inside surface, an outside surface, a top side opening and a generally closed bottom side, the firebowl having the general shape of a hollow spherical segment;
a handle comprising a gripping portion and at least two leg portions, each of the two leg portions at a first end having a flange affixed adjacent to the outside surface of the firebowl, and the gripping portion extending between the two leg portions at a second end, whereby the gripping portion has a spaced positional relationship to the outside surface of the firebowl;
a heat shield affixed adjacent the inside surface of the firebowl and opposite the handle, the heat shield comprising a perimetric edge region and a central region, the perimetric edge region being in at least close proximity to the inside surface of the firebowl and surrounding the central region of the heat shield, at least of a portion of the central region of the heat shield having a spaced positional relationship to the inside surface of the firebowl, whereby the heat shield and inside surface of the firebowl collectively define an at least partially closed volume disposed opposite the handle to form an insulating barrier to insulate the handle from a heated volume of the cooking chamber;
the heat shield being formed from sheet metal comprising stainless steel, whereby the heat shield has a reflective surface to reduce radiation heat transfer; and,
the flange, the firebowl, and the heat shield each having at least one aperture which are correspondingly aligned and through which at least one fastener extends to affix the handle and the heat shield to the firebowl, the fastener including a spacer disposed between the heat shield and the inside surface of the firebowl to prevent distortion of the heat shield caused by overtightening of the fastener.
