Abstract
A deadbolt lock system is provided for a swinging door which prevents movement of the deadbolts from a locked position to an unlocked position when the door is open. Movement of the deadbolts from an unlocked to a locked position when the door is opened is prevented by a slide plate which is locked into a deadbolt deactivating position by a plunger which is biased outward when the door is opened. The system also provides for an unlocking of the deadbolts and an opening of the door with a single rotation of the inside handle.
