A door lock mounted on a front door or the like is generally equipped with a mortise lockset having a latch bolt and a dead bolt. The latch bolts and the dead bolts are mounted on the side of the mortise lockset and operated by the door handle and the rotary knob.

As a lock device such as a door lock, a mechanical method that is to be manually locked and unlocked, and an electric method that can be locked / unlocked using a solenoid or a motor are generally used. In addition, an electronic lock device for determining an accessor using a device for inputting a password, for example, a keypad device, a fingerprint recognition device, a card reader, and the like, has also been widely used in recent years. The electronic lock provides a high level of security compared to other methods by the electronic user authentication process.

On the other hand, in the case of an electronic locking device employing a Mortis lockset, especially in a stand-alone type operated by a built-in battery, the locking state can be firmly maintained, but it is inconvenient to manually operate the dead bolt to release the locking state. There is this. In the case of adopting a structure that automatically releases a dead dead bolt in a locked state, power consumption is large and battery life is shortened.

In addition, a mechanical lock with Mortis Lockset can provide a solid lock by Mortis Lockset's dead bolts, but it does not provide an auto re-locking function and requires careful check of the lock. .

The present invention has been proposed to solve the problems described above, and to provide a mortise locking system that can provide automatic visibility and robust reliability.

Referring to the drawings, the inner door lock cover 200 has a main control circuit 220, a battery 230 for supplying the operating power. As described above, the outer door lock cover 300 includes a keypad 330 and a motor 340 and a mechanical assembly 350 for controlling the mechanical locking / unlocking state of the outer door handle 310. . The keypad 330 and the motor 340 are electrically connected to the main control circuit 220 by the first and second connector cables 322 and 342, respectively.

The inner / outer door handles 210 and 310 are coupled to the door handle mounting groove 151 of the mortise lockset 100 by first and second rotation shafts 260 and 360, respectively. The inner door handle 210 is coupled with the mortise lockset 100 so as to open the door 400 at all times, but the outer door handle 310 is always locked so that the door 400 is not entered without a password. Can not open.

In order to open the door 400 from the outside, a password must be input through the keypad 330. The password inputted through the keypad 330 (which is converted into an electrical signal by the keypad 330) is sent to the main control circuit 220. The main control circuit 220 drives the motor 340 to open the door 400 when it is determined that the authenticity of the input password is appropriate. As the motor 340 rotates, the mechanical assembly 350 interlocked with the motor is operated to open the door by the outer door handle 310. That is, in the locked state, the second rotation shaft 360 does not rotate in conjunction with the outer door handle 310. However, while the mechanical assembly 350 is operated by the motor 340, the second rotation shaft 360 is interlocked by the outer door handle 310. After the door is opened, the motor 340 again rotates to switch the mechanical assembly 350 to the previous locked state.

Referring to FIG. 4, as the door 400 is closed, the trigger bolt 110 is inserted and then returned to the protruding state by the first spring 111. As the trigger bolt 110 is inserted, the first locking arm 140 rotates by returning the engaging jaw 112 engaged by the return spring 113. Accordingly, the departure-preventing washer 123 moves until it comes in contact with the tension maintaining plate 122 so that the dead bolt 120 protrudes to be locked. As the first pivotal arm 140 rotates, the stopper 130 rises to prevent the dead bolt 120 from retreating. Thus, the locked state of the door is maintained.

Subsequently, the unlocking process of the Mortis lockset 100 will be described with reference to FIG. 5. When the inner / outer door handles 210 and 310 connected to the door handle mounting groove 151 rotate, the second pivot arm 150 interlocks the stopper pin 153 to rotate the first pivot arm 140. As the first pivotal arm 140 is rotated in conjunction with the dead bolt 120, the anti-separation washer 123 and the locking jaw 112 are interlocked so that the dead bolt 120 reverses. Since the end of the first pivotal arm 140 is engaged with the locking jaw 112, the open state is maintained. In addition, the stopper 130 is lowered by the interlocking pin 141 installed in the middle of the first pivotal arm 140 to release the restriction on the insertion of the dead bolt 120.

As such, the mortise lockset 100 is locked at the same time as the door 400 is closed by the trigger bolt 110 and the dead bolt 120 are interlocked, and the outer door handle is always locked in the locked state, and the inside door handle Stay free at all times. When opening the door 400, after inputting the password into the keypad 330, only the outer door handle 310 can be opened to open the door 400 is convenient to use and dead by the movement of the handle to open the door As the bolt 120 is operated, power consumption for releasing the locked state is minimized.

In this embodiment, the electronic locking system has been described as an example, but in the case of the mechanical locking system, the mortise lockset of the present invention as described above can be used. In other words, it can be easily implemented by those skilled in the art by adding a configuration that can be locked / unlocked by a mechanical method except for devices for electronic locking / unlocking.

Although the configuration and operation of the self-correcting mortise locking system according to a preferred embodiment of the present invention as described above has been shown according to the above description and drawings, this is merely an example and does not depart from the spirit of the present invention. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope.
