Multi-point locking system and astragal
View Patent ↗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.
1. 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.
2. An astragal according to claim 1 further comprising:
a lower seal block movable between a non-sealing position and a sealing position and having a bolt passage therethrough, the lower shoot bolt being slidably disposed in the passage and the lower seal block being operatively coupled to the actuator;
wherein the actuator is configured to substantially simultaneously move the lower shoot bolt from its recessed position to its deployed position and the seal block from its non-sealing position to its sealing position.
3. An astragal according to claim 2 further comprising a resilient seal disposed on a lower end of the lower seal block.
4. An astragal according to claim 1 further comprising a shoot bolt spring that biases the upper shoot bolt toward its extended position when the upper shoot bolt is in its extended position, and a lower shoot bolt spring that biases the lower shoot bolt toward its deployed position when the lower shoot bolt is in its deployed position.
5. An astragal according to claim 2 further comprising a seal block spring that biases the lower seal block toward its sealing position when the seal block is in its sealing position.
6. An astragal according to claim 1 wherein each latch pawl pivots about a vertical axis as the latch pawls move between their active and inactive positions.
7. An astragal according to claim 1 further comprising a plurality of latch keepers configured to be affixed along a non-hinged vertical edge of a cooperating door panel such that each latch keeper vertically aligns with one of the latch pawls, and wherein each latch keeper includes a pivoting keeper pawl that outwardly extends from the non-hinged vertical edge of the cooperating door panel.
