Latch device of cockpit door of an aircraft |
摘要 |
<p>A latch device for detecting pressure reduction of a cockpit in an aircraft and releasing a bolt and a stopper device are provided so as to prevent a cockpit door from unexpectedly opening by an impact. A main latch device 100 of the cockpit door has a frame 112 fixed to a door panel, and a latch base 120 is mounted to the frame 112 capable of pivotal rotation with a pin 122 as a fulcrum. A bolt 132 is inserted into a catch in conjunction with a door handle 130. A holding/releasing portion 150 holds the latch base 120. When a pressure difference occurs between a cockpit 4 and a cabin 5, a pressure-sensing piston 160 is pushed in, a trigger 170 and a flapper 180 are rotated and the latch base 120 is released. A stopper device 190 regulates movement of the trigger 170 by movement of an inertial piston 192 when an impact force is applied from the cabin 5 side.
