Abstract

Claims (19)

1. A multipoint locking system comprising:

an elongated body having an upper aperture, a lower aperture, and a deadbolt opening therein;

an upper latch pawl disposed in the upper aperture and being pivotable about a first vertical axis extending generally along the body between a first retracted position and a first extended position;

a lower latch pawl disposed in the lower aperture and being pivotable about a second vertical axis extending generally along the body between a second retracted position and a second extended position; and

a pair of actuation members within the housing, each actuation member engaging a respective latch pawl to move the latch pawls to their respective extended positions; and

an actuator cam pivotable about an axis generally perpendicular to the pawl axes and disposed within the deadbolt opening; the actuator cam being coupled to the actuation member and pivoting to move the actuation members in response to movement of a deadbolt into the deadbolt opening in the body.

2. A multipoint locking system according to claim 1 wherein the body is an astragal comprising upper and lower shoot bolts.

3. A multipoint locking system according to claim 1 wherein the body is a vertical frame member.

4. A multipoint locking system according to claim 3 wherein the vertical frame member is a side jamb.

5. A multipoint locking system according to claim 3 wherein the vertical frame member is a mullion.

6. A multipoint locking system for a door panel having a non-hinged vertical edge and being pivotally disposed within a doorframe having a vertical frame member that is proximate to the non-hinged vertical edge when the door panel is in a closed position in the doorframe, the locking system comprising:

an upper latch pawl disposed in an upper aperture in the vertical frame member and being pivotable about a first vertical axis extending generally along the vertical frame member between a first retracted position and a first extended position;

a lower latch pawl disposed in a lower aperture in the vertical frame member and being pivotable about a second vertical axis extending generally along the vertical frame member between a second retracted position and a second extended position;

a first actuation member within the housing engageable with the upper latch pawl to move the upper latch pawl to the first extended position;

a second actuation member within the housing engageable with the lower latch pawl to move the lower latch pawl to the second extended position;

a deadbolt opening in the vertical frame member; and

an actuator cam operatively coupled to both the first and second actuation members, the actuation cam being disposed in the deadbolt opening and being pivotable about a generally horizontal axis, the actuator cam being configured to substantially simultaneously cause the first and second actuation members to engage with the upper and lower latch pawls respectively to move the upper and lower latch pawls between their retracted and

extended positions in to a deadbolt being received in the deadbolt opening.

7. A multipoint locking system according to claim 6 further comprising an upper latch keeper and a lower latch keeper configured to be affixed along the door panel such that the upper latch keeper vertically aligns with the upper latch pawl and the lower latch keeper vertically aligns with the lower latch pawl, wherein the upper and lower latch keepers each include a pivoting keeper pawl that outwardly extends from the non-hinged vertical edge of the door panel.
