Claim:
A gravity hinge assembly for a swinging door, the gravity hinge assembly comprising: a rotating cam cylinder including a head portion at a first end and a first angled cam surface at a second end, wherein the head portion of the rotating cam cylinder includes a discontinuous raised wall portion defining a seating depression across the head portion; a stationary cam cylinder including a projecting nipple at a first end and a second angled cam surface at a second end, wherein a cross-section of at least one of the rotating cam cylinder and the stationary cam cylinder is continuous, the cross-section being a plane parallel to at least one of the first and second angled cam surface; a connection plate adapted to translate rotation of the door to the rotating cam cylinder, wherein the connection plate includes an interior portion configured in mating relation to the seating depression across the head portion of the rotating cam cylinder such that upon seating the interior portion of the connection plate within the seating depression, the connection plate is substantially prevented from axial rotation relative to the rotating cam cylinder; and a wall mounting bracket including a nipple acceptance opening disposed through a leg projecting away from a mounting wall and adapted to accept the nipple projecting from the stationary cam cylinder.
