Claim Text:
1. A hinge mechanism comprising: a hinge frame with at least one support plate slidably mounted on an arcuate plate guide on an interior surface of the hinge frame; a cam slidably mounted on an arcuate cam guide on an interior surface of the at least one support plate, the cam including an inner cam surface, at least one outer cam surface, and a mounting portion for mounting a moveable component to the cam, the inner cam surface and the at least one outer cam surface having different surface profiles; a cam follower pivotably mounted within the hinge frame and including an inner follower surface positioned to be engageable with the inner cam surface, and at least one outer follower surface positioned to be engageable with the at least one outer cam surface, the inner follower surface and the at least one outer follower surface having different surface profiles; and a hinge spring mounted within the hinge frame and that applies force to the cam follower such that the cam follower is held in contact with the cam in at least some positions of the hinge mechanism, the hinge mechanism being configured such that during movement of the cam, contact between the cam and the cam follower transitions between contact between the inner cam surface and the inner follower surface, to contact between the at least one outer cam surface and the at least one outer follower surface, thus enabling the hinge mechanism to snap into different preset open positions.
