Patent attributes
A hinge assembly includes a first monument piece having a first knuckle and a monument leaf attached, and a second monument piece having a first knuckle and a monument leaf attached to the first knuckle of the second monument piece, with the second monument piece spaced apart from the first monument piece by a monument piece space. A door piece includes an intermediate door knuckle extending across the monument piece space, and a door leaf coupled to the intermediate door knuckle. A pin extends through the first knuckle of the first monument piece, the first knuckle of the second monument piece, and the intermediate door knuckle. When the hinge assembly is mounted to a door and monument, a space is formed between the intermediate door knuckle and the monument to define a vent gap through the hinge assembly.
