Abstract: A multipoint door lock system comprises a door frame having a bolt opening and a secondary opening. A latch takes an activable position when the door is opened and a pre-armed position when the door is closed. A door-locking tip of the latch protrudes from the secondary opening of the door frame and into a secondary bore of the door when the door is closed. A transfer block moves from an inactive position to an active position upon insertion the deadbolt in the bolt opening. A biasing element causes a displacement of a translating member when the transfer block moves to the active position in the absence of a force sufficient to cause a compression of the biasing element. This action of the translating member locks the latch in its pre-armed position within the secondary bore.

A lock bolt is pivotally mounted within the lock frame and extends through it for engagement with a door keeper in a door frame. A lock bolt detent is pivotally mounted to the slide member for maintaining the lock bolt in a secure position when the door is closed. Actuation of movement of the slide member results in movement of the lock bolt detent away from the lock bolt followed by pivotal motion of the lock bolt as a pin on the slide member engages the lock bolt and lifts clear of the door keeper. The door is sprung open by a spring loaded plunger which extends out of the lock frame.
