Description

Description: TECHNICAL FIELD The present invention relates to an elevator passenger rescue device, and more particularly to an elevator passenger rescue device provided in a building having an entrance door provided with an electric lock.

[Prior Art] Conventionally, as shown in, for example, Japanese Patent Publication No. 59-17017, a telephone station connected via a telephone line is provided outside a dedicated telephone device such as an interphone connecting the inside of a car and a management office. There has been proposed an elevator passenger rescue device provided with a specific telephone. In such a conventional elevator passenger rescue device, when the car stops not at the landing position but at a position between the floors and the passenger is locked in the car, that is, when the car becomes canned, the in-car communication device is used. Call the outside with
They are now seeking rescue from the car. Then, when the calling device at the management office does not answer despite the call from the calling device in the car, the specific telephone is called by the automatic dialing means and the telephone is communicated with the specified telephone via the telephone line. As described above, it seeks rescue from the car.

[Problems to be Solved by the Invention] By the way, in the case of a recent building, etc., an entrance door provided with an electric lock which can be unlocked from a place away from the entrance of the building, an ID card, and an electric lock which can be unlocked by operating a numeric keypad. Installation is increasing.

Then, an accident occurs in which a passenger is trapped in a car of an elevator in a building having such an entrance door, and a request for rescue from the car is received by the above-described conventional elevator rescue device. When dispatching rescuers to the above building, the rescuer usually does not have a key device such as a lock to unlock the electric lock or an ID card, so stay in the building until you find and obtain this key device. There is a problem that it is not possible to enter, and the rescue operation from the inside of the car is delayed. In particular, there is a concern that when a person is not in a building besides the passengers trapped in the car, it takes time to obtain the key device.

The present invention has been made in view of such a situation in the related art, and an object thereof is to provide a key device of an electric lock when a rescuer arrives at a building to rescue a passenger trapped in a car. It is an object of the present invention to provide an elevator passenger rescue device that can open an entrance door and enter a building without need.

[Means for solving the problem]

In order to achieve this object, the present invention provides an elevator passenger rescue provided in a building having an entrance door provided with an electric lock which can be locked and unlocked by an electric signal, and including an in-car communication device for making a call with the outside of the car. In the device, an entrance / exit communication device capable of communicating with the in-car communication device is provided near the entrance / exit door, and an operation means for outputting an electric signal for unlocking the electric lock is provided in the car. It has a configuration.

[Action]

Since the present invention is configured as described above, when a rescuer arrives at a building in response to a request for rescue from the car and the electric lock of the entrance door is locked, it is provided near the entrance door. A call is made from the entrance / exit communication device to the in-car communication device to notify the passenger that the vehicle has arrived for rescue. Then, when the passenger operates the operating means in the car, the electric lock of the entrance door is unlocked by the electric signal output from the operating means. This allows the rescuer to open the entrance door and enter the building without the need for an electric lock key device.

〔Example〕

Hereinafter, an embodiment of an elevator passenger rescue device of the present invention will be described with reference to the drawings.

FIG. 1 is an explanatory view showing one embodiment of an elevator passenger rescue apparatus of the present invention.

An entrance door 2 installed in a building 1 shown in FIG. 1 includes an electric lock 3 which can be unlocked and unlocked by an electric signal. A control unit 3a for controlling the electric lock 3 is provided near the entrance door 2. Connected to a card reader (not shown).
In addition, the elevator car 4 moves up and down in the building 1.

The passenger rescue device for an elevator according to the present embodiment is provided near the entrance door 2 and the in-car communication device 5 for communicating with the outside of the car 1, for example, a communication device of a control center (not shown). An entrance / exit communication device 8 capable of communicating with the in-car communication device 5; and operating means provided in the car 4 for outputting an electric signal for temporarily unlocking the electric lock 3, for example, an unlock switch 9. And The in-car communication device 5 can be connected via a telephone line 6 to a monitoring center 7 for monitoring the presence or absence of an abnormality in a number of elevators and building equipment (not shown).

In this embodiment, a power outage or the like occurs while the passenger A is getting on and off the car 4, and the car 4 stops at the inter-floor position instead of the landing position, and the passenger A When the passenger is in a locked state, that is, when the container is in a canned state, the passenger A activates the in-car communication device 5 to call the communication device in the management office (not shown). If the communication device of the above-mentioned management office does not answer within a predetermined time despite this call, the monitoring center 7 is called by an automatic dial means (not shown), and the monitoring center 7 is connected to the monitoring center 7 via the telephone circuit 6 in the car. Device 5
Connect. Therefore, the passenger A reports that the car is canned in the car 4 and requests rescue from the car 4.

When the rescue worker B arrives at the building 1 in response to the rescue request from the car 4 and the electric lock 3 of the entrance door 2 is locked, an entrance provided near the entrance door 2 is provided. The communication device 8 makes a call to the in-car communication device 5 to inform the passenger A that the vehicle has arrived for rescue, and requests the unlock switch 9 to be operated. When the passenger A breaks the plastic plate (not shown) that covers the unlocking switch 9 in the car 4 in response to this communication and presses the unlocking switch 9, an electric signal is output from the unlocking switch 9 and the electric signal is output. The control section 3a unlocks the electric lock 3 by this.

In the embodiment configured as described above, when the rescuer B arrives at the building 1 to rescue the passenger A trapped in the car 4, the entrance door 2 is opened without the need for the key device of the electric lock 3. To enter the building 1.

〔The invention's effect〕

Since the present invention is configured as described above, when the rescuer arrives at the building to rescue the passengers trapped in the car, the entrance door is opened without needing the key device of the electric lock and the inside of the building is opened. Therefore, there is an effect that the passenger can be quickly rescued from the inside of the car as compared with the conventional case requiring the key device.
