Description

[Detailed description of the invention] B. Industrial application fields: The present invention relates to an improvement of a door lock device.

Conventional technology: Mechanical locks that are opened and closed using a key are most commonly used for door locking devices, but with the development of integrated circuits, complex and sophisticated electric locks are becoming more and more popular for buildings with special uses. It is used.

The problem that the invention aims to solve. :Using an electric lock with the required number of electrical contacts inside the lock body of a mechanical door lock,
In order to electrically obtain information about opening and closing the door, it is necessary to run an electric wire through the hinge and inside the door, and then connect it to the lock body.

However, inside the existing door, so that it cannot be seen from the outside,
Due to the structure of the door, it is almost impossible to pass electric wires through the door, and even if you force it through, it will often damage the appearance, so it is better to get a new door and lock and throw away the old one. It was normal.

It was also extremely difficult to convert an existing mechanical lock system in an apartment or hotel to an electric lock system, requiring all doors and locks to be replaced and the entire system to be rewired.

In order to avoid the inconvenience of wiring to the door lock, the lock catch is replaced with an electromagnetic catch (Elpctro-+agnetic).
5trike), there is a method of wiring only on the outgoing side, but the drawback is that the electromagnetic catch can only be used to ``unlock'' the lock.

There is also a system lock that incorporates a permanent magnet inside the dead bolt of the door lock, and uses a strike sensor on the pillar side to detect the movement of the dead bolt and emit an electric signal. In this case, special locks for this system had to be used from the beginning.

In either case, it is extremely difficult to convert an existing mechanical lock system to a new electric lock system, requiring a large amount of cost and effort.

21.Object of the invention: To provide a locking system for small and medium-sized buildings, offices, hotels, condominiums, and other buildings equipped with conventional mechanical locking systems.
