Alternatively, the drive pulley and the driven pulley is made of a chain pulley, the belt member may be made of a chain structure to be engaged thereto.

Preferably, the present invention includes a first operation pulley which is integrally rotated with the emergency key insert exposed to the outside of the door; And a second manipulation pulley interlocked with the first manipulation pulley via a belt member, the second manipulation pulley coupled to forcibly rotate the driven pulley during rotation thereof.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 schematically shows the configuration of the present invention installed on the inner body (A) of the digital door lock.

Referring to FIG. 2, the present invention mediates a motor unit 100 that is forward / reversely rotated according to a control signal, a drive pulley 105 coupled to a rotation shaft of the motor unit 100, and a belt member 110. A driven pulley 115 connected to the drive pulley 105 and a movable means for advancing or reversing the dead bolt 40 with respect to the striker of the door frame in conjunction with the rotation of the driven pulley 115.

As the belt member 110, a timing belt may be preferably employed. At this time, the driving pulley 105 and the driven pulley 115 is composed of a timing pulley engaged with the timing belt. Therefore, when the driving pulley 105 is integrally rotated with the rotation shaft of the motor unit 100, the timing belt precisely engaged thereto rotates to transmit power to the driven pulley 115.

Alternatively, the belt member 110 may be made of a chain structure. At this time, the driving pulley 105 and the driven pulley 115 may be made of a chain pulley meshed with the chain structure.

When the driven pulley 115 is rotated by the power of the motor unit 100, the rotational force is transmitted to the dead bolt 40 via the movable means. In this case, as the movable means, a variety of well-known configurations for converting the rotational motion into the horizontal motion to move forward / backward of the dead bolt 40 may be adopted.

For example, the movable means is connected with the dead bolt 40 and the spindle 125 which rotates integrally with the driven pulley 115, the operation lever 130 protruding from the spindle 125, and the dead bolt 40. It may be configured to include a movable member 135 is moved forward / backward horizontally in conjunction with the rotation of the operating lever (130). At this time, the movable member 135, the long hole 138 may be further formed to the horizontal movement of the movable member 135 with respect to the guide rod 137, the support to correspond to the rotation range of the operating lever 130 The groove 136 is preferably formed to support the end of the operating lever 130.

Therefore, when the spindle 125 rotates in conjunction with the driven pulley 115, the operation lever 130 moves the movable member 135 horizontally, and as a result, the dead bolt connected to the movable member 135 ( 40) moves forward or backward with respect to the striker in the door.

In the present invention, the movable means is not limited to the above configuration and can be variously modified by employing a known technique.

One side of the inner body (A) may be further formed with a coupling hole 120 for the combination of the door handle 30 described above. The coupler 120 is formed in a conventional gear assembly (not shown) for releasing the latch bolt 50 against the striker during its rotation.

On the other hand, preferably in the outer body (B) of the digital door lock, the first operation pulley 140 and the first operation pulley 140, which is integrally rotated with the emergency key inserting portion (140a), and the belt member 145. A second operation pulley 150 for forcibly rotating the driven pulley 115 may be further provided. In addition, one side of the outer body (B) may be further formed with a coupler 155 for the combination of the door handle 70 described above.

The second operation pulley 150 receives the rotational force from the first operation pulley 140 forcibly rotates the driven pulley 115, that is, forcibly rotates regardless of the power transmitted from the driving pulley 105. To substantially apply the movable force to the dead bolt (40). Here, a variety of known techniques can be employed for the coupling structure for forced rotation.

The second operation pulley 150 and the driven pulley 115 may be preferably configured integrally, may be coupled via a predetermined power transmission means.

As the belt member 145, preferably, a timing belt may be employed. At this time, the first operation pulley 140 and the second operation pulley 150 is made of a timing pulley meshed with the timing belt. Therefore, when the first operation pulley 140 rotates as the user rotates the emergency key in the state in which the emergency key is inserted into the emergency key insertion unit 140a exposed to the outside of the door 1, the timing belt engaged with the first operation pulley 140 is precisely interposed. The rotational force is transmitted to the second operation pulley 150 to rotate the driven pulley 115.

Alternatively, the belt member 145 may have a chain structure. At this time, the first operation pulley 140 and the second operation pulley 150 may be made of a chain pulley meshed with the chain structure.

Then, the operation of the dead bolt operating device according to the present invention having the configuration as described above will be described.

When the first dead bolt 40 is locked to the striker side and the motor unit 100 is driven and rotates forward by the operation of the keypad 60, the belt member 110 having a timing belt or a chain structure is preferably rotated. A very accurate rotational force transmission operation is performed from the driving pulley 105 to the driven pulley 115 as a medium.

At this time, since the driven pulley 115 is mechanically connected to the dead bolt 40 via the movable means, the rotation of the driven pulley 115 immediately leads to the backward movement of the dead bolt 40 to substantially the striker The unlocking operation of the dead bolt 40 is made.

On the other hand, when the motor unit 100 is driven to rotate in reverse according to the manipulation of the keypad 60, the opposite operation is performed while the locking operation for the dead bolt 40 is made.

In addition, the outer body (B) has a second rotational pulley 150 for forcibly rotating the driven pulley 115, and the rotational force to the second operation pulley 150 accurately via the belt member 145. Since the first operation pulley 140 is provided, it is possible to release the dead bolt 40 regardless of the driving state of the motor unit 100 by the user's emergency key operation.
