Description

A mortise}

The present invention relates to a mortice in which a dead bolt and a latch bolt firmly hold a closed state of a door when the door is locked and a user can open the door easily when the door is opened.

Generally, door lock assemblies are installed for security of doors. Recently, the development of digital door lock assemblies is increasing.

Conventional digital door lock assemblies are disclosed in Japanese Patent Registration No. 10-543831, Japanese Patent Laid-open No. 10-0680945, and Registration No. 20-0356813.

Conventional digital door locks include a mothesis assembly inserted into a door, an interior handle coupled to the inside and outside of the door, and an outdoor handle. The mortise assembly includes a case and dead bolt and latch bolt projecting outwardly from the case. In a conventional digital door lock assembly, when a user inputs a predetermined authentication key such as a password, the dead bolt moves to the inside of the case, and the door is locked or unlocked in the door frame so that the door is locked or unlocked.

The latch bolt is engaged or disengaged with the door frame in the same manner as the deadbolt, in association with the movement of the indoor or outdoor knob provided outside the case so that the user can rotate by hand.

The double locking of the dead bolt and the latch bolt can further enhance the security of the door.

However, in order to catch or release the dead bolt, a dead bolt driver is provided inside the case. The conventional deadbolt driver is operated by a mechanical operation such as the insertion of an electronic signal or a key. However, the conventional deadbolt driver has a problem in that it has a complicated structure, increases the manufacturing cost, and has a high risk of malfunction or failure at the time of driving operation.

In order to solve such a problem, Patent No. 10-1184346 has been proposed.

In this patent, dead bolt and latch bolt are included in the casing, and the dead bolt is linearly moved in conjunction with the rotation of the action gear portion that is rotationally driven according to whether an electric signal or a key is inserted for locking and unlocking of the dead bolt And the connecting rod is bent in such a manner that the connecting rod is moved in the outer peripheral tangential direction of the action gear portion when the action gear portion is rotated.

In addition, the latch bolt is driven by a separate driving means.

However, in the case of the above-mentioned registered patent, the mechanical structure of the action gear part is constituted by a mechanism that can cause an error, so that a long life time loss is often caused, and means for driving the dead bolt and the latch bolt are separately constructed, There is a problem that the failure rate is also high as the driving means is formed separately.

Particularly, since the motis itself is operated by the electric signal, the problem that the motor becomes inoperable even when the power is not good is exposed.

In order to solve the above-mentioned problems, the present invention provides a mortise which can be inserted into a striker without a dead bolt and a latch bolt, .

Another object of the present invention is to fix the latch bolt part by using two components of the dead bolt part and the latch bolt fixing part so as to improve the fixing force and improve the reliability of the door crime prevention.

It is a further object of the present invention to simplify the apparatus so that it can operate in a non-powered manner without errors.

The present invention is characterized in that a latch bolt portion that maintains a fixed state by a dead bolt that is set in a locked state when a door is closed and a dead bolt portion including the dead bolt is formed, .

In addition, when the door is closed and the lock is set, the latch bolt portion can be fixedly secured through the dead bolt portion and the latch bolt fixing portion to further improve reliability. When the dead bolt portion is unlocked, the latch bolt portion can freely move And the convenience of the user can be improved.
