The present invention relates to a door lock device that is automatically opened, and more specifically, when a person approaches or a fire occurs within a certain distance from the inside of the door, it detects it and keeps the door open to operate the inside of the door without operating the inner handle. The present invention relates to a door lock device that is automatically opened so that the door can be pushed out.

Normally, the locks installed on the doors for use in residential facilities and security purposes to restrict the access of outsiders are mechanical door openers (keys / locks), card door openers, Various types of door opening and closing devices, such as a voice recognition door opening and closing device and an opening and closing device for opening and closing the door by a password input, have been applied.

However, recently, in order to overcome the problems caused by the mechanical wear and tear of the mechanical door opening and closing device among the above-described door opening and closing device and to use the low-cost door opening and closing device while preventing inconvenience caused by the loss of the key, card or password input is required. Many devices for opening and closing the door through the use has been widely used.

However, such a door opening and closing device is cumbersome at the time of entry and exit because the door is operated by the inside and outside handles to open the door in the always locked state.

That is, when the person carrying the luggage in both hands, there was a problem that the operation of the handle is difficult because the handle is difficult, and in the case of a fire, the mechanical configuration mounted on the door is damaged, so that it is difficult to operate the handle. Since the handle contact is not possible due to heat, there is a problem that human injury is caused due to difficulty of entering and exiting through the door.

The present invention is devised to solve the above problems, the accessor or fire occurs within a certain distance of the inside of the door in the state that the operating member of the door lock locking device mounted to the door is inserted into the latch portion, It is an object of the present invention to provide a door lock device that is automatically opened so that the door is opened by automatically releasing the operation member from the latch portion after detecting this.

Automatically opening the door lock device of the present invention for achieving the above object; A door lock device for automatically opening a door when a person approaches or fires inside the door, comprising: an optical sensor for detecting a person's approach to a predetermined location inside the door, or a fire sensor for detecting heat and smoke in response to a fire At least one or more independently mounted or integrally mounted as one module, the detection signal receiving unit for wirelessly receiving the detection signal according to the accessor access detection and the fire occurrence detection by the optical sensor, transfer the detection signal from the detection signal receiving unit And a microprocessor controlling the operation member, which is inserted into the door latch part and is in the locked state, is slidably moved by the solenoid drive to open the door, and a selection switch for selecting the reception selection operation of the detection signal receiver. The unit part is provided And a gong.

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

1 is a block diagram illustrating a door lock device that is automatically opened according to an embodiment of the present invention, Figure 2 is a schematic perspective view showing that the door lock device according to Figure 1 is installed in the door.

As shown, a door opening / closing unit part 100 having an operation member 130 which is inserted into and departed from the door latch part 20 and slidably moves on the side of the door so as to open and close the door is embedded in the door 10. It is installed, the door opening and closing unit 100 is a solenoid 120 for sliding the operating member 130, the microprocessor 110 for controlling the drive of the solenoid 120, and the following sensors (210, 220) A detection signal according to a person's approach or a fire is received and transmitted to the microprocessor 110 so that the microprocessor 110 drives the solenoid 120 to open a door. And a selection switch 150 for selectively turning on / off a sensing function of the sensing signal receiver 140.

In addition, at least one detection sensor module unit 200 for transmitting a detection signal to the detection signal receiving unit 140 is mounted on the ceiling or the side of the door 10.

The sensor module module 200 may include a first sensor (for example, an optical sensor) 210 for detecting a human body shape, not an animal, and a second sensor (for example, a fire sensor) for detecting a fire, for example smoke or heat ( 220 is provided.

In addition, the selection switch 150 turns on / off the driving of the detection signal receiver 140 and automatically opens the door 10 according to the sensor detection when the driving signal is turned on for user convenience. In the off driving, the sensor detection is not driven and the visitor directly opens the door 10 by operating the inner handle 160.

Next, the operation of the present invention will be described with reference to the accompanying drawings.

First, the person can select the door opening method by selectively operating the selection switch 150, when the selection switch 150 is off-drive the person directly inside the handle as in most door opening and closing method (160) Rotating the operating member 130 can be moved out of the door latch portion 20 to enter and exit, and when the selection switch 150 is on-drive as in the present invention approaching the door 10 or a fire, etc. When the door 10 is automatically opened, it will be described.

3 is a state diagram used for explaining that the door is opened according to the sensor detection of the present invention.

As shown, when an accessor approaches the inside of the door 10, that is, within the sensor response range of the human body sensor, the first sensor 210 detects that the accessor has approached, and the detected detection signal. To the detection signal receiving unit 140 of the door opening and closing unit 100 spaced a predetermined distance.

When the sensing signal receiver 140 transmits the received sensing signal to the microprocessor 110, the microprocessor 110 transmits a control signal for driving the solenoid 120 on.

Then, the solenoid 120 is a mechanical element coupled to one end, for example, a gear is driven to slide the drive member 130 to move away from the door latch portion 20. Here, since the series of mechanical driving methods in which the operating member 130 is driven in accordance with the solenoid 120 is applied in a general known art, detailed description thereof will be omitted.

When the operating member 130 is separated from the door latch part 20 according to the sliding drive of the operating member 130, the door is in an open state, and thus an accessor may open the door without operating a separate inner handle 160. You can go out while pushing (10).

After the person exits, the microprocessor 110 drives the solenoid 120 according to a sensing operation of a sensor (not shown) interposed in the side of the door when the door 10 is closed to control access from outside. The operation member 130 is inserted into the door latch portion 20. For example, the outside can be accessed only by a separate handle operation or unlocking operation.

On the other hand, in the event of a fire, as described above, the entrance and exit of the door 10 must be kept open rather than the locked state. That is, when a fire occurs, the door 10 is opened once a fire is detected because it must be able to quickly exit to the outside as an emergency situation.

To this end, as in the case of detecting the human body as described above, the second sensor 220 provided in the sensor module module 200 detects whether heat or smoke is generated and mediates the detection signal to the detection signal receiver 140. To the microprocessor 110.

Likewise, the microprocessor 110 drives the solenoid 120 and drives the operation member 130 in one direction according to the mechanical driving to separate the operation member 130 from the door latch 20 so that the door 10 may be opened. To open.

Once the door 10 is opened, the microprocessor 110 stops the solenoid 120 from being driven until the door 10 is opened until a separate operation, for example, a person directly operates the door handle and locks it. ) Will continue to open.

That is, when a fire occurs, the door 10 is initially opened according to the fire detection fact, and the door 10 is damaged or damaged by a heat source before the fire is extinguished, so that the door 10 cannot be artificially opened. In this case, the door 10 may not be opened at this time, and casualties due to the entrance and exit may be generated.

Therefore, when the microprocessor 110 detects a fire, the microprocessor 110 should continue to open even after the door 10 is opened.

On the other hand, as described above, in addition to the sensing sensor module unit 200 is installed on the ceiling or the side of the inside of the door 10, when a person approaches within a certain distance, the detection signal receiving unit 140 receives a signal for opening the door. A sensor module unit (not shown) in the form of a remote controller may be provided to allow the access person to receive and generate a predetermined signal.

Even when the sensor module unit only approaches the inside of the door 10, the detection signal receiver 140 receives a signal from the sensor module unit and slides the operation member 130 according to the control operation of the microprocessor 110. Move to open the door 10.

Of course, the radio signal frequency for opening the door should be set in advance by the sensor module unit and the microprocessor 110.

In addition, a separate key is provided to the sensor module unit and may be configured to generate a signal for opening the door when the key is operated.

As described above, according to the present invention, when a visitor approaches or a fire occurs by a sensor mounted at a predetermined location inside the door, the controller detects this and transmits a detection signal to the door opening / closing unit. By opening the door, the door is automatically opened when an accessor approaches, making it easy to enter and exit, and evacuating to the outside regardless of damage or damage to the door opener due to the automatic opening of the door, especially in the event of a fire. It can work.

On the other hand, the present invention is not limited to the above-described specific preferred embodiment, any person having ordinary knowledge in the field to which the present invention belongs without departing from the gist of the present invention claimed in the claims can be variously modified. will be.
