Abstract
Abstract A hinge structure for a barbecue grill which affords positive holding between the base and cover. The cover has extending flanges with end engaging portions to abut against the rear wall of the base and the base has stop members spaced from the rear wall of the base to engage the cover when the cover is in an open position. A flange interconnects the base stop member and serves as a bearing surface for the cover with an undercut portion of the stop providing a retention feature for a ledge on the cover.
