Abstract
A multipoint locking system includes a body having an upper aperture and a lower aperture therein. An upper latch pawl is disposed in the upper aperture and is pivotable about a first vertical axis between a first retracted position and a first extended position. A lower latch pawl is disposed in the lower aperture and is pivotable about a second vertical axis between a second retracted position and a second extended position. At least one actuator is configured to move the upper and lower latch pawls between their retracted and extended positions. The body can be an astragal, a vertical frame member, or the like.
Claims7
An astragal comprising:
- an elongated housing having an upper end and a lower end, the housing being configured for external attachment along a non-hinged vertical edge of a swinging door panel;
- an upper shoot bolt slidably disposed in the housing proximate to the upper end, the upper shoot bolt being movable between a retracted position and an extended position;
- a lower shoot bolt slidably disposed in the housing proximate to the lower end, the lower shoot bolt being movable between a recessed position and a deployed position;
- an actuator comprising a lever that is selectively movable between an unlocked position and a locked position, the actuator being operatively coupled to both the upper shoot bolt and the lower shoot bolt, and when the lever is in the unlocked position, the upper shoot bolt is in its retracted position and the lower shoot bolt is in its recessed position, and when the lever is in the locked position, the upper shoot bolt is in its extended position and the lower shoot bolt is in its deployed position;
- a first latch pawl at least partially disposed within the housing and being pivotable about an axis generally parallel to a longitudinal axis of the housing, between an inactive position substantially contained within the housing and an active position wherein a portion of the latch pawl projects from the housing;
- a second latch pawl at least partially disposed within the housing spaced from the first latch pawl, the second latch pawl being pivotable about an axis generally parallel to a longitudinal axis of the housing, between an inactive position substantially contained within the housing and an active position wherein a portion of the latch pawl projects from the housing;
- A pair of actuation members within the housing, each actuation member engaging a respective latch pawl to move the latch pawls to their respective active positions;
- and
- an actuator cam pivotable about an axis generally perpendicular to the latch pawl axes and disposed with an opening in the housing that aligns with a deadbolt to be received in the opening;
- the actuator cam being coupled to the actuation members and pivoting to move actuation members in response to movement of the deadbolt into the opening in the housing.
