DOOR LOCK SYSTEM BEING ABLE TO REMOTELY UNLOCK}

The present invention relates to a door lock system, and more particularly, to a door lock system capable of remote unlocking, which is configured to remotely open a door by electric power in a door lock having a latch bolt and a dead bolt.

In general, the lock device installed in the door has been developed a lot of technology to maintain a high security.

That is, the door lock has been developed in various ways such as having a unlocking structure by various mechanical key combinations or unlocking by inputting an encrypted code by an electronic control device.

However, various door locks created by these conventional technologies have a common problem that it is difficult to unlock the door remotely.

Looking at this problem, in the case of a pure mechanical door lock, the latch bolt and the dead bolt may be formed by only the latch bolt or double lock.

In the case of the mechanical door lock it is made to open the lock by a way to release the inside or to release the key from the outside.

Such a door lock has a problem that it is very inconvenient to use because it is impossible to unlock at all.

In addition, there is a lock device made by adding a solenoid to the mechanical door lock to unlock the lock by electric and open the door. Such electric unlocked door locks include Korean Utility Model Publication No. 96-5229.

When the electric unlocking mechanism is added to the mechanical lock as described above, the problem of the remote unlocking as described above may be solved, but the structure is very complicated and there is a problem in that the entire assembly must be replaced with a necessary door lock.

In addition, since the door lock has to be supplied with power to the pivoting door, the installation is not easy and a problem occurs frequently during use.

On the other hand, a door lock having a more precisely controlled door lock having a mechanical structure as described above and a control device having various functions is known.

Such electronic door locks include Korean Patent Publication Nos. 93-9088 and 93-9091. These electronic door locks have improved security by various electronic encryption technologies when attempting to unlock the locks from the outside. It has the disadvantage of having a complicated configuration, and has the disadvantage of being quite expensive in price.

All the door locks according to the prior art described above are configured to be electrically unlocked or locked by adding an actuator such as a solenoid and a motor for unlocking to a lock device formed on the door, so that the door locks of various types installed without replacing existing door locks are installed. Is difficult.

On the other hand, in the conventional gate, such as a single-family house, the lock device that forms a remote release while the lock is rotated by the solenoid has been used for a long time, but this conventional technology is fundamentally different from the present invention. That is, the present invention will be described later, but the main technical idea is to form the release means to the door frame so that it can be unlocked remotely while maintaining the function of the door lock is that any type of door lock can be accommodated.

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

The present invention includes a rotation lock (10) for accommodating the latch bolt and the dead bolt of the door lock and unlocking and locking according to the rotation, a drive unit (20) comprising a solenoid and a trigger coupled to the operation shaft of the solenoid, and the rotation A latch 30 for maintaining or releasing a restraining force between the lock 10 and the drive unit 20, a door frame-shaped housing 40 incorporating the component, and a cover 60 for closing the housing up and down. 62).

The rotation lock 10 is formed of a "c" shaped clasp, one side of which is a tapered surface 11, and the other side forms a support surface 12 to be pushed by a latch bolt or a dead bolt of the door lock, The protrusion 15 is integrally formed behind. In addition, the spring support 13, which is supported by the spring 80 and has an extension shaft 14, is fixedly coupled to both sides of the "c" shaped clasp.

The drive unit 20 fixedly installs the solenoid 21 on the fixed plate 22 so as to release the rotation lock 10, which has been locked by the remote control signal, by the remote release signal from the restrained state, and operates the solenoid operating shaft 21a. ), The trigger 23 of the flat plate having the protrusions 23a and 23b formed thereon is held by a spring 23c to be hinged with the fixing plate 22, and is joined by a screw 25.

The latch 30 forms a protrusion 31 which is in contact with the protrusion 15 of the pivot lock 10 at one central portion thereof, and is supported by the spring 34 on both sides of the opposite side to support the fixing plate 22. A protrusion 32 is formed, and in the center portion, a trigger surface 33 is formed to be interviewed with the protrusion 23a of the trigger 23 and the thickness thereof is thinly cut to facilitate the trigger.

On the other hand, a housing 40 is provided for housing these components so that the rotation lock 10, the drive unit 20, and the latch 30 interact with each other.

The housing 40 has a two-stage stepped structure that matches the outer shape of the door frame, and provides a central opening 41 for accommodating the rotational lock 10 and inserts the spring 80 on both sides of the opening. Drills the installation hole 42 formed the spring installation hole 43 for.

Between the center opening 41 and the installation hole 43 is provided with a bearing groove 44 for installing the shaft 14 of the rotation lock (10).

In addition, in order to install the drive unit 20, the drive unit installation hole 45 is drilled and the drive unit 20 is fixedly coupled by screwing from the rear surface, and the installation hole 45 and the center opening 41 are installed. In the bottom portion of the latch 30 is formed by forming a latch groove 46 for recessing the protrusion 31 so as to be slidable.

On the other hand, by inserting and coupling the rotation lock 10 to the center opening 41 to form a bearing 44a for supporting the shaft 14 of the rotation lock so that the rotation is possible screwed into the bearing groove 44 This is accomplished.

The upper cover 60 is formed as a bracket covering the upper surface of the housing 40 and coupled to a conventional door frame, and a lower cover 62 is formed to close the lower surface of the housing. It is made by puncturing the opening (63) to test-trigger the trigger (23).

Each component made as described above is coupled to enable interaction in the housing 40.

That is, when the rotation lock 10 is inserted into the center opening 41 of the housing, the spring support 13 is located in the installation hole 42 and the shaft 14 is positioned in the bearing groove 44 and the shaft 44 44 By the shaft. At this time, the elastic force by the compression spring 80 inserted into the spring installation hole 43 is formed to act on the end of the spring support (13). Therefore, when the restraint force applied to the rotation lock is released, the rotation lock is made to rotate by the elasticity of the spring 80.

On the other hand, the drive unit mounting hole 45 of the housing 40 is inserted into the drive unit 20 is provided with a solenoid and a trigger.

The drive unit 20 is firmly coupled to the housing by the fixing plate 22.

The latch 31 is inserted into the latch groove 46 by inserting a latch 30 that substantially restrains or releases the rotation lock 10 between the rotation lock 10 and the drive unit 20. At the same time, the trigger surface 33 is engaged with the protrusion 23a of the trigger 230 and has a compression spring 34 which provides an actuation force when it is switched from the unlocked state to the locked state. It is made by coupling between the coalescing between and closed by the cover (60,62) in the upper and lower.

Looking at the operation of the present invention constituting the configuration as described above in more detail below may be more easily understood.

First, among the door locks formed on the existing doors of the present invention, preferably, the latch bolts are mounted in the horizontal direction while being fitted into or away from the opposing grooves provided in the door frame, and thus can be applied to all door locks that are locked and unlocked.

The door lock may be a cylinder lock, a door lock having a latch bolt, and a door lock having a double lock having a dead bolt together with the latch bolt.

The present invention is cut and embedded in the size of the housing 40 in the opposite position door frame 100 of the door lock 101 is already formed and coupled to the door frame as a cover 60.

At the same time, it is installed by extending the power line to enable electric drive remotely and its operation switch is installed at the user's required place. Such electrical power and actuation switches may typically be made to be controlled in an interphone, video phone, or the like.

In the door lock system of the present invention, which is constructed as described above, the lock bolt of the latch lock 101a and the dead bolt 101b formed in the conventional door lock 101 are provided in the rotation lock 10. It is located at (11a).

At this time, the rotation lock 10 is in a state in which rotation is impossible because the protrusion 15, the protrusion 31 of the latch 30, the trigger surface 33, and the protrusion 23a of the trigger 23 come into contact with each other. It is constrained to keep the door locked firmly.

When the external visitor is confirmed and wants to release the door, when the power is applied by operating an operation switch (not shown) provided remotely, the solenoid 21 of the driving unit 20 sucks the operation shaft 21a by the power. Accordingly, the trigger 23 coupled to the operating shaft 21a rotates upward in the drawing about the hinge point A formed at the lower end of the fixed plate 22.

Therefore, as the protrusion 23a is separated from the trigger surface 33 of the latch 30, the restraining force applied to the rotational lock 10 is released, and the rotational lock is released. When the visitor continues to pull the door open, the rotation lock 10 is pushed by the latch bolt 101a to be rotatable and releases the door.

At this time, it should be noted that the existing door lock can be opened without any operation for disengagement, and this is the greatest advantage of the present invention which can be remotely disengaged door lock system.

When the door is pulled open, the rotation lock 10 rotates while pushing the latch 30 by the elastic force of the compression spring 80. Here, the elastic force of the spring 80 and the spring 34 is required to be designed such that the compression spring 80 to be the release lock 10 release position is relatively large.

In addition, at this time, the solenoid 21 of the driving unit 20 is considered to be able to operate even if the driving power is not continuously applied and the instantaneous operating power is applied. This forms a gap with the width of the lock groove 11a slightly larger than the thickness of the latch bolt 101a, and the protrusion 23a of the trigger 23 is latched by the rotation lock 10 which is rotated into the minute gap. 30) is pushed back and the trigger surface and the trigger surface 33 are mutually displaced, so that the unlock state is maintained until the door is opened by the user's external force.

Here, as described with respect to the spring force, the action of displacing the latch 30 and the trigger 23 in the mutually released state by moving the minute gap is performed by the force of the spring 80 described above.

Therefore, the user can unlock the door remotely so that the user can open the door without checking the door.

Then, the case of maintaining the locked door again as follows.

When the door is unlocked and the door is rotated again to reach the door, the latch bolt 101a and the dead bolt 101b of the door lock 100 come into contact with the support surface 12 of the rotation lock 10 and the external force. When the rotation lock is rotated by the external force, the latch 30 is advanced to the original position by the elastic force of the compression spring 34, and the trigger 23 is reversely rotated by the elasticity of the tension spring 23c. The state where the trigger surface 33 abuts against the protrusion 23a of the trigger is reproduced.

Therefore, as described above, it can be seen that the restraint state of the rotation lock in the locked state is achieved.

Here, the tapered surface 11 of the rotation lock 10 is provided to allow the user to open and close the door only with the existing door lock in a situation where the door is simply touched or opened while the dead bolt is not locked.

As described in detail above, the present invention can be remotely unlocked. The door lock system does not add a device for electrically unlocking the door lock as in the prior art. This makes it very simple to remotely disarm.

And forming the electrical operation structure in the door frame as described above has the effect of being electrically stable and easy to install compared to the structure for supplying power to the rotating door.

In addition, since the present invention supplies power only at the initial stage of operation, power consumption is negligible so that the power consumption is negligible, and it can be replaced by existing door frames. .

In addition, the use of locking or opening the door lock with a key is maintained as usual, so it is not inconvenient to use or tampered with new habits, and once the door lock has been unlocked once, it is lost to reverse the lock. It can be prevented even if it is destroyed.

As described above, the present invention solves the shortcomings of the conventional techniques of forming a power opening / closing mechanism and a corresponding power structure of a relatively complicated structure for remote opening of a door lock having a latch bolt and a dead bolt. It is a very good invention having various effects to enable remote opening.
