(h), the outer grip b is not rotated and cannot be opened from the outside. In addition, even if the lock button c is pressed inside, the inside handle a can be rotated so that the lock button c can be returned to open the door at the same time as a partial rotation.

And, in the door lock to release it from the outside, when the key (k) is inserted and rotated using a key hole provided in the center of the outer handle (b), the hinge (f) is rotated by the rotation of the operating rod (h) lock button (c) returns and the door can be opened.

However, in these door locks, the doors are opened and closed with keys one by one several times in daily life, which is inconvenient according to this problem. And when you lose a key, you have to find the key maker and order another identical key to solve it, or even to forcibly dismantle it to open it.

In addition, the door lock as described above was often opened with iron wire in the locked state, such as economical double burden, such as the need to install the auxiliary lock, there was a disadvantage in preventing theft.

On the other hand, another conventional technique that is relatively related to the present invention is known in the Korean Utility Model Publication No. 405 "button type ruler ball" (notification number 79-787).
