DOOR MECHANISM FOR CELLULAR TRANSCIEVER

摘要

A unique hinge construction is provided for pivotally connecting a cover to a main body of a transceiver. The main body comprises a base and upstanding sidewalls and an endwall. Movable between a closed position generally overlying the main body and an operative angularly disposed position, the cover includes a pair of spaced apart ears projecting from an end thereof, the ears having opposed key slots formed therein being aligned with opposed mounting bores in the sidewalls adjacent the endwall. A pair of hinge shafts are rotatably received in an associated one of the mounting bores in the sidewalls on the main body. Each hinge shaft includes a key member engageable with an associated one of the key slots in the opposed ears for rotation therewith and a central member having a uniformly contoured outer surface defined by elevationally opposed convex shaped lobes, laterally opposed concave shaped depressions, and smooth transition zones joining the lobes and said depressions. A pair of spring members, each having a convex shaped surface fixed to the main body are biased into engagement with the uniformly contoured outer surface of its associated shaft for maintaining the cover closed in one instance and in at least one operative position relative to the main body in another instance.
