Abstract

An outdoor cooking appliance, such as a “Barbeque Grill”, having a body and a lid. The lid is connected to the body by a hinge assembly and is movable between a first, closed position and a second, open position. As the lid is moved between the first and second positions, the hinge assembly counterbalances the weight of the lid so that the lid does not close of its own accord and may be positioned at one of plurality of positions intermediate between the closed and the open positions. The hinge assembly includes two arms that are pivotally interconnected. The hinge assembly preferably includes a linkage that interconnects the one of the two arms of the hinge assembly to the lid to permit the hinge to reside in a location that is relatively removed from and remote to the lid so that the hinge assembly. In a further embodiment, the hinge is adjustable.
