Abstract
The invention provides a catch device of a cockpit door of an aircraft with improved safety. A cockpit door 1 disposed between a cockpit 2 and a passenger cabin 3 in an aircraft comprises a door body 10 that opens toward the cockpit via a hinge 12. A latch device 100 for opening and closing the door is provided on the cockpit side, and a bolt 120 thereof engages with a catch device 200 provided on a wall adjacent to the door. The catch device 200 has a solenoid device which restrains the rotatably disposed catch device by electromagnetic force. When trouble occurs to the solenoid, the restrained status of the catch member is released and the cockpit door may be opened. In such case, a pit pin 300 is inserted to the catch device to restrict rotation of the catch member.
