Abstract: A system and method for a universal locking system that mounts to any type of door, clamping and reinforcing the door from both sides. The system and method is compliant with the intent of CMS, NFPA, TJC codes & standards, allowing the occupant to participate in his own decision to run, hide or fight. Wall-mounting the locking device and allowing the occupant to remove the device and install it at the door complies with the ANSI “Knowing Act” and requires the occupant to activate the locking device. Removal of the device from the wall mounting, immediately alerts first responders of potential sheltering-in-place while providing a remote audio/visual alarm, while identifying location of the device. Alert locations include nurse stations, staff locations, building securing desk/offices and fire command. A key override is provided so that responders/authorities can gain entry without requiring any special knowledge of the locking configuration.

A slide bar is fixable in a locked position and an unlocked position, wherein the slide bar is biased in the unlocked position. A knob slider is adapted to move the slide bar into the locked position such that the latch moves to the closed position and engages a notch of the slide bar to fix the slide bar in the locked position. A servo motor is adapted to rotate a servo cam in a second rotational direction to move the slide bar into the locked position, and is adapted to rotate the lock cam in the first rotational direction to move the slide bar into the unlocked position.

Abstract: A door lock mechanism for an overhead door employs a sliding pin or rod that passes into the path of the rollers in the track, and obstructs the roller from movement in the direction to open the door. A spring in the door lock frame biases the sliding pin towards a proximal open position. The sliding pin has an arm that extends radially from its proximal end, and which engages retaining structure at the proximal end of the door lock frame. The arm is rotated out of engagement with the retaining structure to release the pin so it may slide proximally to an unlocked position. The pin may slide into a receiver housing mounted on a door panel.
