The present invention relates to a digital door lock having a panic function.

The conventional digital door lock is composed of an inner case installed on the indoor side, an outer case installed on the outdoor side, and a lock box provided with a dead bolt. The lock box is provided with a dead bolt, a dead bolt driving unit, a solenoid, etc. therein, and when a password is input through a keypad attached to an outer case or a key is inserted, power is applied to the solenoid formed inside the lock box. The dead bolt is configured to retract into the lock. In addition, when the button formed on the inner case is pressed or the unlocking device is turned on, the dead bolt is retracted into the locking device while power is also applied to the solenoid. In this way, when the handle is turned while the dead bolt is released, the latch bolt connected to the handle is released and the door is opened.

However, such a conventional digital door lock is difficult to open the door quickly in case of fire or emergency, even when the door is to be opened indoors, the door must be opened by pressing a button or rotating the lock device to release the dead bolt and then turning the handle. There was a downside.

In order to solve the above problems, the lock side is released only by rotating the handle in the indoor side, and the digital side with the panic function to unlock the lock state only by inserting a password or inserting a key as in the past. Door locks are designed.

The digital door lock having a conventional panic function has a double rotating body coupling structure, and includes a lever driving unit to release both the dead bolt and the latch bolt when the inner knob is rotated to release the locked state.

1 and 2, the operation of the lever driver having the panic function will be described in detail.

The lever drive unit is connected to the inner handle 51 and the outer handle 11, the panic lever 41 is connected to the inner handle, the outer handle is connected by the handle connector 61, the handle is inserted, the handle connector is inserted It consists of the 1st rotating body 21 provided with the groove | channel 25 to which it is made, and the 2nd rotating body 31 provided with the groove | channel 35 which inserts a panic lever.

The first rotor 21 is connected to the latch bolt driver 140 inside the lock box, and the second rotor is connected to the dead bolt driver 130 inside the lock box.

Therefore, when the inner handle 51 is rotated, the panic lever 41 coupled with the inner handle rotates, and the panic lever is inserted into the groove 35 formed in the second rotating body 31, so that the panic lever rotates. The second rotating body also rotates. Meanwhile, since the second rotating body is connected to the dead bolt driving unit 130, the dead bolt driving unit 130 is rotated by the rotation of the second rotating body, and as a result, the dead bolt 110 is shown in FIG. 2B. Will retract into the lock.

In addition, when the inner handle 51 is rotated, the handle connector 61 connected to the inner handle 51 rotates, and the handle connector is configured to be inserted into a groove formed in the first rotating body. When the sieve rotates, the first rotating body 21 also rotates. Since the first rotor is connected to the latch bolt driver 140, the latch bolt driver is rotated by the rotation of the first rotor. As a result, as shown in FIG. 2B, the latch bolt 120 is inside the lock box. Will retreat.

On the other hand, the outer handle 11 is connected to the first rotating body by the handle connecting body, but is not connected to the second rotating body 31, the second rotating body does not rotate even if the outer handle is rotated. As a result, rotating the outer knob unlocks only the latch bolt, and the dead bolt does not unlock, so the door will not open. Therefore, if you want to open the door outdoors, the dead bolt should be released by applying power through a password or inserting a key like a conventional digital door lock.

As such, when the door is opened outdoors, it is inevitable to use a digital method of applying power, so if the user forgets the password or there is a problem in the circuit, the door cannot be opened from the outside. In order to make up for this drawback, most digital door locks are equipped with emergency lock devices. The emergency lock device of the existing digital door lock is mounted on the front of the outer case, and the permanent lock device is directly connected to the dead bolt drive, and when the key is inserted and rotated, the dead bolt drive moves and releases the dead bolt.

However, the existing emergency emergency device is located in the front of the product has a disadvantage of making it easy to be completely exposed to the person attempting to unlock fraud.

In addition, since the dead bolt drive inside the lock and the lock device must be connected, the internal structure was complicated.

In order to solve the above problems, the present invention is to arrange the lock device of the digital door lock in a narrow space at the bottom of the outer case, making it difficult to operate illegal unlock, and by not using a direct connection method directly connecting the lock device and the dead bolt drive unit The purpose is to simplify the internal structure.

The present invention relates to a digital door lock having a panic function. The present invention is characterized in that the lock device is installed in a narrow space at the bottom of the outer case unlike the lock devices of the conventional digital door lock are installed on the front portion of the outer case installed in the outdoor portion. As such, if the lock device is located at the bottom of the product, there is an advantage that it is difficult to negate the conventional product because it is forced to take an unstable posture when attempting to negate it.

In addition, the present invention is characterized in that it takes a concise manner that does not directly connect the lock device with the dead bolt drive. Existing key devices use an electronic method in which the dead bolt drive unit is rotated together when the key is connected to the dead bolt drive unit of the lock box to rotate the key, or when the key is inserted, the power is applied. In the former case, the internal structure is complicated because the connection part for connecting the key holder and the dead bolt driving part is provided. In the latter case, the circuit does not operate when the circuit is broken or power is consumed.

However, the present invention does not connect the dead bolt drive unit and the locking device, but instead, the locking device is connected between the first and second rotors to connect the two rotors, and the second rotor and the dead bolt driver are connected. There is an advantage of simplifying the internal structure by using a concise method of releasing the dead bolt using the connection. In addition, by using the mechanical unlocking method, instead of the electronic unlocking method, it is possible to release the lock even when the circuit is broken or the power supply is cut off. On the other hand, according to the mechanical unlocking method does not generate such a beeping sound, there is an advantage that can be delayed because the negative unlocker can not immediately know whether the door is open.

The digital door lock according to the present invention comprises a lever drive having a panic function (that is, an outer handle, an inner handle, a handle connector, a panic lever, a first rotating body and a second rotating body) and a key holder. Among the above components there is in particular a characteristic element of the invention in the first rotating body and the key holder.

 According to the present invention, the first rotating body has a protrusion formed on the surface thereof, an opening is formed on one side of the protrusion, the locking device for coupling the first rotating body and the second rotating body below the opening. Characterized in that the mounting. In addition, according to the present invention, the key holder is characterized in that it consists of a bar (bar) in contact with one end of the locking device, a key cylinder and a key insertion hole located in the lower side of the bar and rotated by the rotation of the key. .

Among the constituent parts of the present invention, the inner handle, the outer handle, the handle connecting body, the panic lever, and the second rotating body constituting the lever driving unit have the same function as the lever driving unit of the digital door lock performing the conventional panic function.

That is, the outer handle and the inner handle are mounted on the inner case and the outer case of the digital door lock, respectively, and are connected by the handle connector 270. Therefore, by rotating the handle of either one by the handle connector 270 is rotated in conjunction with the other handle.

In addition, the panic lever is attached to the inner handle, moves in conjunction with the movement of the inner handle, is inserted into the groove 320 formed in the second rotating body (310).

In addition, the handle connector 270 is connected to the inner handle and the outer handle rotates when the handle is rotated, it is inserted into the first groove 250 formed on the surface of the first rotating body 310 to be described later. The first groove 250 is formed on the surface of the first rotating body 310 to match the shape and size of the handle connector to fix the handle connector 270, inserting the handle connector into the groove Rotating the handle also rotates the first rotating body.

In addition, the second rotating body 310 has a second groove 320 for inserting the panic lever on the surface thereof, and a third groove 330 for allowing the handle connecting member 270 to pass therethrough. Characterized in that. At this time, the second groove 320 should be formed with the same width as the panic lever so as to move according to the movement of the panic lever, the third groove 330 is connected to the handle so as not to move in conjunction with the movement of the handle connector. It should be constructed wider than the radius of rotation of the sieve.

The second rotating body 310 is configured to be connected to the dead bolt driving unit inside the lock box (not shown). That is, when the second rotor 310 rotates, the dead bolt driving unit rotates by the rotational force, and thus the dead bolt can be released by retreating the dead bolt into the lock box.

Next, the first rotating body and the key holder forming the features of the present invention will be described in detail with reference to FIGS. 3 to 6.

The first rotating body 210 of the components of the present invention has a first groove 250 that can be fixedly inserted into the handle connector 270 on the surface. The first groove 250 should be formed in the same shape as the cross section of the handle connector to secure the handle connector 270. Accordingly, when the handle is turned, the handle connector 270 inserted into the first groove 250 rotates like the handle, thereby rotating the first rotating body 210.

In addition, the first rotor 210 is connected to the latch bolt driving unit inside the lock box, and when the first rotor rotates, the latch bolt driving unit rotates to release the latch bolt.

In addition, the first rotating body should have a protrusion 230 formed on its surface, and should be equipped with a locking device 240 for coupling the first and second rotating bodies.

As shown in FIG. 3, the protrusion 230 has to be formed with an opening 220 so that the locking device 240 can be inserted at one side.

In addition, the sliding device 240 of the sliding method to be mounted to the lower side of the opening (220). The locking device is formed in a b-shaped shape, the body portion of the b is pushed the locking device while the bar of the key holder, which will be described later, rotates, and slides into the opening of the protrusion, wherein the head of the locking device is second It is configured to be attached to the rotating body. That is, the first rotating body and the second rotating body are fixed to each other by the locking device so as to move together.

On the other hand, the key holder of the components of the present invention, as shown in Figure 4,

The bottom surface of the key holder 400 is formed with a key insertion hole 410 for inserting the key, the cylinder portion 420 to rotate together when the key is inserted into the key insertion hole and the upper portion of the cylinder It is mounted to the bar (430) is configured to rotate in conjunction with the rotation when the cylinder rotates.

The bar 430 rotates to push the locking device 240 toward the opening 220, whereby the body of the locking device slides to the opening 220 of the protrusion 230 on the surface of the first rotating body. The head of the locking device is attached to the second rotating body 310.

Using the present invention described above to look at the method of unlocking the lock device of the digital door lock having a panic lever.

As already mentioned, the digital door lock equipped with the panic lever is unlocked only by turning the knob on the indoor side, but unlocked only by pressing a password or inserting a key on the outdoor side. This is because the first rotating body and the second rotating body have a dual rotating body structure that moves independently.

However, in the present invention, the locking device is provided between the first rotating body and the second rotating body, and the rotating device is fixed by the locking device so that the two rotating bodies move together. When the knob is turned, the lock can be released.

Looking specifically at the above process,

First, insert the key into the key holder mounted on the bottom of the outer case and rotate it. As the key rotates, the key cylinder rotates, and thus, the bar mounted on the upper part of the key cylinder rotates to push the locking device which is in contact with one side of the bar. As a result, the locking device is slid into the opening of the protrusion formed on the surface of the first rotating body. At this time, the head portion of the locking device in close contact with the opening of the protrusion is coupled to the second rotating body, whereby the first rotating body and the second rotating body are coupled to move together.

When the outer handle is rotated while the first rotating body and the second rotating body are coupled by the locking device as described above, the handle connector connected to the outer handle and the inner handle rotates, and has a groove for inserting the handle connector. The first rotating body rotates. As described above, since the first rotating body is connected to the latch bolt driving part, the latch bolt driving part rotates by the rotation of the first rotating body to release the latch bolt.

However, since the first rotating body and the second rotating body are connected by the locking device, when the first rotating body rotates, the second rotating body also rotates. Since the second rotating body is connected to the dead bolt driving unit, when the second rotating body rotates, the dead bolt driving unit rotates, and as a result, the dead bolt is released.

Therefore, both the dead bolt and the latch bolt are released and the locked state is released. That is, by using the digital door lock of the present invention through the above process, it is possible to unlock the lock simply by inserting and turning the key outdoors and driving the external handle.

According to the present invention, the key cylinder is mounted on the narrow surface of the lower end of the outer case of the digital door lock, so that those who want to unlock the key without inserting the key cannot easily release the key cylinder.

In addition, the present invention uses a mechanical operation method, rather than the electric power to drive the dead bolt, so that a beep or the like does not occur when the door is opened, it is determined whether those who attempt to unlock the unlocked state Not immediately known has the effect of delaying the negative unlock.

In addition, the present invention does not adopt a direct connection method that directly connects the dead bolt driving unit of the key cylinder and the lock box, and has a simple effect of adopting a simple formula to simplify the internal structure.
