  • Patent number: 6186444
    Abstract: A sliding pocket door adapted for aircraft use comprising two generally tabular door segments, each laying in a common sliding plane and each attached to a carrier frame which is mounted to an aircraft bulkhead. Each door segment is attached to its carrier frame by unique hinges that allow the door segment to rotate out of the sliding plane while simultaneously dropping along their axes of rotation. This rotation will allow a nondestructive depressurization of the doors, for example, during rapid decompression in the aircraft.
