Abstract
The present invention comprises a simple deadbolt assembly for hinged doors. The deadbolt assembly includes a deadbolt slideably mounted between two side plates for movement between an extended position and a retracted position. A cam is rotatably mounted between the side plates and actuates movement of the deadbolt upon rotation of the cam. The cam is mounted through an elongated opening in the deadbolt and includes an actuating arm with a guide. The guide is positioned within a corresponding guide channel formed in the deadbolt. Upon rotation of the cam, the guide is rotated through the guide channel and the force of the cam guide is transferred to the deadbolt causing the deadbolt to move between its extended and retracted positions. Opposing leaf springs are mounted to the deadbolt, along the length of the elongated opening to engage the cam and prevent binding between the cam and deadbolt during actuation of the deadbolt. The leaf springs further compensate for imprecise manufacturing tolerances as well as varying loads on the deadbolt.
