Abstract
A security pocket door traverses within a security bulkhead wall that defines a pocket, within which the pocket door traverses, and a through passage to permit people, carts and luggage to pass. The pocket door has an upper door track mechanism and a lower door track mechanism that engages a corresponding upper and lower track mechanism of the bulkhead and floor, respectively. The bulkhead door locks with at least one solenoid with a locking pin that engages a hole in a tab of the pocket door. The locking pin creates a magnetic field with a magnet located in the tab to send a signal to the flight deck in order to indicate a closed and locked or an unlocked pocket door condition. When the pocket door is in its closed position, the door perimeter overlaps the bulkhead on at least three sides of the door and also overlaps with the floor.
