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.

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.

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.

An integrated lock body system for securing access points. An electronic door lock has a lock body, at least one electrical component within the lock to be monitored, and at least one output for connection to an external unit located remotely from the electronic door lock for monitoring load resistance between the external unit and the electronic door lock. A circuit is mounted adjacent to or within the electronic lock body. The circuit includes an electrical connection to the at least one electrical component within the electronic door lock and an external electrical output for connection to the external unit. The circuit further includes at least one resistor between the electrical connection to the at least one electrical component within the electronic door lock and the external electrical output, the at least one resistor imparting a desired load resistance capable of being monitored by the external unit.

A latch assembly for a door includes automatically deployable deadbolt. When the door is closed and the latch engages a strike plate, the deadbolt automatically extends into a corresponding opening in a door jamb to secure the door.

An anti-ligature handle and escutcheon for operating a lock. The handle and escutcheon are smoothly curved in all directions to eliminate hanging points and prevent suicide by preventing the attachment of a ligature to the handle or escutcheon. The handle is curved to allow fingers to be inserted behind the handle to pull on the handle. The handle is attached to a handle plate that slides behind an escutcheon plate portion of the escutcheon. Multiple ligature traps in the form of an inverted 'V' are positioned in parallel offset rows between the handle plate and the escutcheon plate to prevent the insertion of a ligature around the handle and handle plate.

The present invention provides a pin and tumbler cylinder lock and a retrofitted cylinder lock which minimizes unauthorized openings of the lock by bumping. The cylinder lock utilizes specially designed driver pins which are correlated in size to the largest possible stack height of the tumbler pins with a bump key inserted in the plug portion of the lock and the shear line height of the lock. All the driver pins are about the same height and preferably symmetrical with a lip on each end. The invention also provides a method for retrofitting existing locks by removing at least one of the driver pins and replacing the removed driver pin or pins with the driver pins of the invention.

A fire plate for receiving a bored in lock assembly and preventing passage of fire through a lock opening bored perpendicularly through a fire door. The fire plate is particularly adapted for use with integrated lock and latch assemblies that are designed for installation through a latch opening bored from an edge of the door into the lock opening. The latch opening has a diameter less than the lock opening and the fire plate blocks the space above and below the lock assembly in the lock opening to prevent the passage of smoke and fire through the lock opening. The fire plate includes two fire stop barriers that may be formed by bending from a sheet of spring steel and which preferably snap into engagement with the lock assembly as it is inserted from the latch opening into the lock opening.
