2. Description of the Related Art In a conventional door of this type, a lock body is mounted inside a door on a door end side, and an engagement hole for engaging with a latch or dead bolt is formed on an end surface of a door frame facing the door end side of the door. And a gap between the top and bottom of the door with respect to the door frame and the door tip side is formed somewhat wider, and the lock is formed in a trapezoidal shape protruding from the end surface of the door frame. . When the door frame is deformed due to an earthquake or the like and the upper surface of the lock catch comes into contact with the end surface of the door, both ends of the trapezoidal lock catch are slid in the height direction of the door frame to open and close the door. Was possible.

[0003]

However, in the conventional structure, the door frame is deformed to a certain degree or more by an earthquake or the like, and the upper side and the lower side of the engagement hole of the lock catch are fixed to the upper surface of the dead bolt and the lower surface of the latch. When it is pressed, it becomes difficult to open and close the door and lock / unlock the lock, so that it cannot function as a door, and there is a fear that damage caused by an earthquake or the like may be increased. In addition, there is a problem that the security is reduced because the latch and the dead bolt can be seen from the gap between the door frame side and the door frame which is formed somewhat wide. In order to improve crime prevention, even if a gap concealment is attached to the end face on the door tip side of the door so that the latch and dead bolt can not be seen from the outside, it will not be a fundamental solution to improve crime prevention,
It costs extra material costs and time and effort. The present invention has been made in view of these circumstances, and even when a door frame is deformed due to an earthquake or the like, the door can be opened and closed, locked and unlocked, and fundamentally improved in crime prevention. The purpose is to provide an anti-earthquake door that can provide a solution.
