What is the real purpose hidden behind the key of the mystery that the blade part turns into a bend?

Atariimae that "key" used by everyone as a necessity of familiar security is sturdy. However, we knew that there was a key that seemed unreliable at Funafuna, which overturned such common sense from the ground, and there were hidden purpose which can be said unexpectedly.

(627) John Coulter's WEIRDEST LOCK ON EARTH !!


This is a mysterious key and a dedicated lock, which turns very suddenly. The key on the right hand is structured so that the contents of the key can be contained in the cartridge on the outside.


Looking at the lock from the front is like this. It is not much different from a normal lock, except that the part where the key is inserted looks a bit complicated. In the bezel part, "HYT" logo and "PATENT" which are regarded as the manufacturer name are written, you can see that it is a key with a patent.


And the special key is here. Normally, the blade part that is engraved in a jagged shape is a straight and straight line, and the parts like something like a small piece are connected to the inside.


The key handle part is engraved with descriptions that have won something prize in 1991 with German-like words.


I tried to illuminate the cylinder part of the lock with light, and I saw how the interior had a stepped structure. This is also a completely different shape from a normal lock.


So how do you actually use this key? First set the key at the insertion opening of the cylinder. It is very ordinary so far.


And hold the handle part ......


"Jack" and slide. Only the handle part slid and the part which was thought to be a blade remained on the outside. It looks as though the key itself is not stuck.


However, turning the steering wheel confirmed that it works properly as a key.


When pulling out the key, hold the handle like when using the syringe ... ...


By pulling out it returned to its original shape.


So what exactly is the structure of the key?


The blade part has a hollow tube structure. Slide the handle from here ......


I do not.


More. Some kind of object like a belt of a chain or a wrist watch came out.


There is no toughness at all, it is a slender condition.


However, when I straightly extended on the palm of the hand, I could see the unevenness like the keys I see mostly is engraved.


But from the side, it is the key of the mystery that you can bend to Kuyaka Nya like this with your fingers. What on earth ......


Its identity is achieved by making the cylinder part of the lock a special shapepickingIt is the key to prevent the damage of 1991, which was patented in the United States in 1991 and published in 1992. You can see that he invented the man as Hsu Yun-Tung in Taiwan.

In the attached illustration of the application form, the state of the lock where the insertion part of the key is bent is drawn in an easy-to-understand manner.


In picking, a special tool or the like is inserted in the insertion port to release the lock, but in the present invention, by bending the insertion slot in the middle, the picking tool is blocked in the middle and unlocked unlocking It is a mechanism to prevent being done.


Although it was quite excellent as an idea, it was an invention that seemed to be effective as picking countermeasures, but there were some reasons such as having problems in practicality such as durability when looking at places that are not so popular I wonder. Inventor Hsu Yun-Tung seems to have done a number of invention related key issues.
