METHOD AND DEVICE FOR OPERATING SAFETY LOCK MECHANISM ON DOOR SIDE IN DOOR STRUCTURE OF AIRCRAFT

摘要

PROBLEM TO BE SOLVED: To provide a method and a device for operating a safety lock mechanism on a door side in a door structure of an aircraft in which the operability of the aircraft door is improved from an ergonomic viewpoint. SOLUTION: In this method, a safety lock shaft 40 of the safety lock mechanism 4 disposed on the door side is operated via a coupling/uncoupling connection mechanism 5 by a driving means 9 disposed on a door frame part side to perform transition between a single latch condition and safety-locked latch condition. In this device, the safety lock shaft 40 disposed on the door side is connected in a coupling/uncoupling manner to the driving means 9 disposed on the door frame part side and connected to an operation shaft 8 via the coupling/uncoupling connection mechanism 5 disposed between a door 1 and a door frame part 2.
