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.

Abstract: Modular vehicle units, including aircraft interior storage units, and associated methods are disclosed herein. One embodiment is directed toward an aircraft system that includes a modular unit and at least one latch or releasable coupler to couple the modular unit to at least one surface of an aircraft. Another embodiment is directed toward a vehicle system that includes a vehicle having a first surface and a second surface. A modular unit can be positioned generally against the first and second surfaces. The system can further include at least one latch or releasable coupler to couple the modular unit to at least one of the first and second surfaces. In further embodiments, the system can include at least one locating device for positioning the modular unit.

Abstract: A self locking fastener system is disclosed for light-weight ballistic resistant applications. The fastener system includes a ballistic resistant cap nut with an integral shoulder. The shoulder is formed onto the mating surface of the cap nut and is keyed to lock with a cut-out in a structural member to which the fastener system is secured. In a commercial aircraft, the cap nut is located on the passenger cabin side of the ballistic resistant flight deck door and prevents tampering therewith that might otherwise lead to disassembly or damage to the fastener system and degrade the ballistic resistance of the door assembly. Thus provided, the fastener system is resistant to removal by manipulation of the cap nut as well as damage from ballistic projectiles. The shoulder of the cap nut increases the shear area of the fastener along the plane of the mating surface thereby enhancing the fastener's resistance to shear loading. The cap nut is constructed of titanium or stainless steel.

Abstract: A dead bolt lock apparatus specifically adapted for use with a flight deck door of an aircraft. The apparatus includes a dead bolt member which can be moved between locked and unlocked positions via a key. A lockout handle is included on the side of the apparatus which faces the flight deck area of the aircraft. The lockout handle is movable rotationally from a first position, wherein it has no affect on the use of the key to unlock the dead bolt, to a second position wherein it prevents the dead bolt from being moved out of a locked position by use of the key. The apparatus thus provides an additional degree of security to occupants of the flight deck by allowing them to prevent unlocking of the apparatus even with the key.
