The latch bolt head may also be configured to move between a first rotational position and a second rotational position, wherein the blocking pin is configured to prevent movement of the latch bolt head from the first rotational position to the second rotational position when the blocking pin is in an engaged position.

Abstract: Techniques for controlling access to zones of a building. The techniques include determining with a computing device configured to regulate access to a zone of the building, at a time and responsive to a request to access the zone of the building received via an access control interface, whether a user is allowed to access the zone of the building; and in response to the computing device determining that the user is not allowed to access the zone at the time, receiving, via the access control interface, a request to permit access to the zone at the time; determining, with the computing device and at the time, whether to permit access to the zone based on one or more criteria; and outputting a result of determining whether to permit access to the zone.

Abstract: A lock having a latch assembly with a bolt head freely movable between an extended position and a retracted position. The latch assembly also includes lock pin that is movable between a locked position and an unlocked position, which may be moveable by a motor and/or biasing mechanism. The lock also has a strike assembly including a strike housing for receiving the bolt head. The strike housing includes a keeper biased to a latched position relative to the bolt head. When the lock pin is in the locked position, the lock pin engages the keeper to hold the keeper in the latched position, and thus the bolt head in the extended position in the strike housing. The lock also includes an access control system for controlling the motor of the lock.

The actuator may include a rod holder including a lockout configured to inhibit disengagement of a rod from the rod holder. The side latch may be a mortise latch which may include a channel configured to receive a nut for alignment during installation. When installed in an associated door, the latching device may withstand multiple impacts from windborne objects or pressures induced by high winds.

Abstract: A status indicator for a locking mechanism may include a status indicator face, a status indicator plate, a cam coupling, and a locking mechanism coupler. The status indicator face and status indicator plate may be at least partially moveable relative to one another. The locking mechanism coupler may have a greater rotational range of motion than the cam coupling. The status indicator face may indicate the state of a locking mechanism and may have a viewing angle greater than or equal to 180 degrees.

Abstract: A dogging mechanism for an exit device may include a progressive latching arrangement to allow for dogging at a plurality of positions of a push bar. An electronic latch retraction device may include a camming arrangement configured to provide mechanical advantage when retracting a push bar of an exit device.

Abstract: A door latch includes a latch bolt and strike plate capable of transferring electricity therebetween. The latch bolt and strike plate may each include one or more complementary electrical leads such that electrical power and/or electrical signals may flow between the complementary electrical leads, when the electrical leads are in contact with one another.

Abstract: A latching device for a door includes an actuator, a first rod, a second rod, a transom latch, and a side latch having a hook latch head. The actuator may include a rod holder including a lockout configured to inhibit disengagement of a rod from the rod holder. The side latch may be a mortise latch which may include a channel configured to receive a nut for alignment during installation. When installed in an associated door, the latching device may withstand multiple impacts from windborne objects or pressures induced by high winds.

Abstract: Disclosed herein is a door lock configured to indicate the lock status of the door lock to nearby persons. In some instances, the door lock includes a locking mechanism with one or more actuators configured to act directly on an indicator such that the indicator indicates the lock status of the lock.

Abstract: A hook bolt for a latch assembly includes a hook that deploys laterally from a deadbolt when the deadbolt is moved to an extended position. When the deadbolt is actuated, the hook automatically deploys perpendicular to the deadbolt movement to an engaged position within a corresponding opening in a door jamb to secure the door.

Abstract: A multi-point latching device may include a mortise lock and one or more remote latches which are operable with a handle. The mortise lock may include a handle lock which selectively locks and unlocks the handle is independently controllable by an actuator and by a lock cylinder. The lock cylinder may be used to unlock the handle during power failure events where the mortise lock is put into a fail secure state, such that the mortise lock maintains normal functionality as a manual device.

Abstract: Systems and methods for controlling the emission of gases and/or flames emitted from one or more electrochemical cells are disclosed. In one exemplary embodiment, gas emitted from an electrochemical cell located within an interior of an enclosure may be flowed through a flow restriction to reduce a pressure and/or temperature of the gas and/or the gas may be flowed through a catalyst prior to exiting through an outlet of the enclosure.

Abstract: Disclosed herein is a door lock configured to indicate the lock status of the door lock to nearby persons. In some instances, the door lock includes a locking mechanism with one or more actuators configured to act directly on an indicator such that the indicator indicates the lock status of the lock.

Abstract: A door exit device may include an actuator, an upper latch, and a lower latch. The actuator may be operatively coupled to the upper latch by a first drive and to the lower latch by a second drive. Each drive may include a housing which is mountable to the exterior of a door panel and a drive rod slidably supported within the housing. The housing may include a base which is mountable to the door panel and a cover attachable to the base with the drive rod located between the base and the cover. The housing may be configured to extend from the actuator to the latch to conceal the entire length of the rod between the actuator and the latch.

Abstract: A button assembly for a door lock may include a button and a shank. The button may be toollessly couplable to the shank to allow force transmission between the button and the shank. The button may transfer linear force and torque along a longitudinal axis of the button to the shank to allow a state of an associated lock body to be changed.
