Abstract
A hinge apparatus has relatively rotatable first and second parts, one of which is adapted to be secured to the phone housing and the other of which is adapted to be secured to a cover. One of the parts comprises a cam and the other comprises a follower, the cam having end stops corresponding to an open and a closed position of the cover relative to the housing, and a convex surface between the end stops to provide initial resistance to rotation of the cover out of the open and closed positions. The parts are spring loaded such that the cover is snapped into the open and closed positions, respectively, once the follower passes the arcuate surface of the cam.
