DOOR OPENABLE IN CASE OF STRUCTURAL FAILURE

摘要

A door openable in case of structural failure has a front face (2) and a rear face (3), vertical hinge and lock sides (4, 5) with a lock latch (6). The door has a major door portion (8) bearing a lock, and at least one end door portion (9, 30), both being enclosed by said front and rear faces (2, 3), vertical hinge and lock sides (4, 5) and a surface (10) inclined downwardly from the front face (2) to the rear face (3). A plurality of energy absorbers are arranged in correspondence of said inclined surface (10) in order to permit an offset of the end door portions (9, 30) with respect to the major door portion (8). A releasing rod (23) for unlocking the lock latch (6) moves upwards under the action of the springs (27), due to said offset, returns the lock latch (6) into the door lock and retains it in unlocked position.
