[Prior art]
Picking, in which doors of various buildings are unlocked illegally by using special tools, is rampant, and theft of burglars and robbery by rehabilitation will not stop. As measures against such illegal unlocking, means to use a lock with a strong and complicated structure, means to make the unlocking operation complicated and difficult by using multiple locks, and install a vibration sensor on the indoor side to respond to abnormal vibration Then, a method of improving the security effect by means of generating an alarm by loud sound or flash, means of strengthening surveillance by a security camera, or the like is recommended.
[0003]
However, no matter how complicated the structure of the lock is, various damages due to the case of attempting to open the lock illegally remain. Furthermore, the number of cases in which the door itself is destroyed and forcedly penetrated by using stronger machines and tools, instead of illegal unlocking, is increasing.
[0004]
In cases where such doors are broken and penetrated, there are cases where the door itself is destroyed using a crowbar or other tools, cases where the deadbolt (bar) catches on the side of the frame (door frame) are destroyed, and cases where the door is provided. It has been pointed out that a door or lock is destroyed by using a mail box or a courier service as a clue.
[0005]
Further, as a means for illegally opening the outward opening door, a case is pointed out in which a hinge (hinge) is broken by cutting or fusing using an electric cutter or an arc cutting machine. In order to protect against such damage, it is effective to adopt a structure in which the hinge does not protrude to the outside. In many cases, it is common to project outside.
[0006]
In the case of an open door that employs a hinge that protrudes to the outside as described above, the lock is made stronger, and even if a plurality of locks are installed, the hinge is cut, melted, or otherwise broken. Then, there is a possibility that the door is easily opened illegally from the hinge side. In other words, no matter how strong the lock is, and even if a plurality of locks are added, the door with the broken hinge can be easily pulled out from the hinge side by using an appropriate tool such as a bar. The door is illegally opened.
[0007]
[Problems to be solved by the invention]
In view of such circumstances, it is an object of the present invention to enhance a crime prevention function that can prevent an illegal door from being opened as long as the lock-side deadbolt is fitted, even if the hinge portion of the outer door is broken. It is an object to provide a door.
