In particular, it is particularly preferable to operate in the event of detecting an object in connection with the detection sensor S.

The operating relationship of the present invention made of such a configuration is as follows.

First, in terms of the security function, the description of the matters previously filed by the present applicant, such as odor or water injection by the detection signal of the object detection sensor S, will be omitted. Will be described only.

When the emergency door 20 is forcibly opened, the tip of the actuating rod 42 must be released from the clamping rod 30 in order to open the emergency door 20. In this case, the actuating rod 42 overcomes the pressure of the elastic spring 44. And retreat to touch the first limit switch 46.

Therefore, the operation state of the emergency door 20 is checked in real time in a remote place such as a security office or a management room according to the transmission signal of the first transmitter 50 which is interlocked by the operation of the first limit switch 46. And action.

In addition, when the emergency door 20 is opened, the operation part of the second limit switch 76 which is suppressed while maintaining the contact state with the wall is moved forward, and the second touch bar 78 interlocked with the second emitter ( The contact state with 80 is released, and at the moment, the second transmitter 80 emits a control signal and emits a warning sound or a warning light to the remote place as in the operation of the first limit switch 46, thereby enabling real-time management. Done.

That is, the second limit switch 76 performs a function of the dual stabilizer to quickly detect the above-mentioned first limit switch 46 even when the first limit switch 46 is not operated due to a defect or failure.

Of course, when it is necessary to open and close the emergency door 20 in good faith during the above-described process, the authorized person can turn off the power supply to stop the energization so that unnecessary operation does not occur.

In addition, another point of the present invention is how the emergency door 20 can be easily opened in an emergency.

In order to implement this, the present invention solved by giving at least one or more functions to the emergency door lock.

First, when normal operation is being made, when the emergency evacuator presses the operation switch 68, power is applied to operate the solenoid 66 to force the operator 64 to retreat.

At this time, the operating rod 42, which is connected by the operator 64 and the connecting rod 62, overcomes the pressure of the elastic spring 44 and the attraction force of the magnet 32 embedded in the fixing clamp 30 As the retracted state with the fixing clamp 30 is released as the retracted to the first limit switch 46 side, the emergency door 20 can be easily opened automatically.

Second, when the solenoid 66 cannot be used due to an emergency, for example, when the operation switch 68 is lost due to a fire or the solenoid 66 is deformed, the emergency evacuator directly handles the lever 60, such as a lever. Can be opened by manually retracting the actuating rod 42 by forcibly applying a strong force.

Third, if both of the above-mentioned cases are impossible or require a significant emergency, the emergency evacuator grabs the emergency door 20 and shakes it (mainly efficient to shake the tip of the operating rod), as shown in FIG. The fuse 96, which is embedded in the emergency cutting magnets 94a and b at the cutting side of the front end part of the c), is disconnected and the part of the length is cut without retracting the operating rod 42. It is possible to release the lock state and thus to easily open the emergency door 20.

On the other hand, when the normal object detection sensor (S) detects the proximity object, the operation of the operation solenoid 120 receives a signal while the pressure rod 122 is moved downward to press the push button of the air reservoir 100 Air inside the reservoir 100 is sprayed toward the access object through the air outlet 104.

At this time, if it contains odor component, the accessor is seriously alert by the odor and hesitates the approach.

At the same time, the return spring 160 is tensioned and the touch rod 126 is raised to be in contact with the counting limit switch 130 and the counter 140 counts the number of times and displays the number on the display window 142.

Therefore, it is possible to visually easily check the amount of remaining air in the inside of the air reservoir 100, thereby facilitating management.

In addition, when the reservoir (180) containing the pigment (W) is laid, the pigment (W) is injected through the injection nozzle 182, so that a stronger warning can be given to the accessor, the pigment ( The malodorous component may be further added to W).

In addition, such operation may vary from a single operation to a continuous operation by having a structure capable of maintaining the energized state continuously for a predetermined time or for a single period or a predetermined period of power supply state applied to the operation solenoid 120. As described above, when the emergency door 20 is required to be opened in good faith as described above, the electric power can be opened in a state in which the power is turned off in advance through consultation with an authorized person.

Finally, in the above-described configuration and operation relationship, the circuit configuration related to object detection, warning broadcast, odor injection, and remote signal transmission is well known and known circuit configuration, and thus the detailed description thereof will be omitted. Various modifications may be made without departing from the scope of the invention.

As described in detail above, the present invention provides the following effects.

First, in the event of an emergency in a building such as a fire, emergency doors can be opened quickly and easily, which can significantly reduce personal accidents.

Second, the emergency door can be prevented from being used for any purpose other than its own purpose by blocking the access of unnecessary people.

Third, remote monitoring is possible to monitor the status of emergency doors in real time.
