2. Description of the Related Art Usually, an elevator car installed in a building is equipped with an in-car communication device such as a telephone or an intercom. This in-car communication device is used in the manager's room of the building. It is connected to the monitoring phone installed in. Then, for example, when an accident occurs in which the passenger is confined in the car due to the failure of the elevator, the passenger operates the call button installed in the car. In response to this operation, a call signal is output, the in-car communication device and the monitoring communication device are connected, and the passenger can talk with the manager. Further, when there is no manager in the building where the elevator is installed, or when the manager disappears at night, a monitoring center for monitoring the building via a communication line is equipped with a monitoring telephone, and, for example, as described above, If an accident occurs in which the passenger is trapped inside the car due to a malfunction of the car, the passenger operates the call button to talk to the staff at the monitoring center via the car in the car and the monitor phone. ing. Recently, the remote monitoring method described later has become mainstream.

In such an emergency call device for an elevator, even if the passenger operates the call button by mischief, the caller in the car and the monitoring room provided in the management room or the monitoring center are provided. Since it is connected to the telephone, the manager or the staff member had to deal with the connection by the mischief. In particular, since the monitoring center monitors multiple buildings where elevators are installed,
There was a problem that the clerk had to deal with a lot of connection by mischief. Therefore, as described in, for example, Japanese Patent Laid-Open No. 3-200682, when the call button is operated while the door of the elevator is open,
There has been proposed an elevator communication device that judges a mischief and blocks the connection between the in-car communication device and the monitoring communication device.

[0004]

By the way, in the above-described conventional elevator communication device, when the call button is operated by mischief while the elevator is traveling, the in-car communication device and the monitoring communication device are connected to each other. Will be connected. Therefore, it has not been possible to completely prevent the connection between the in-car communication device and the monitoring communication device due to mischief.

The present invention has been made in view of the above-mentioned problems, and an object thereof is to prevent the in-car intercom and the monitoring intercom from being connected to each other by mischief while the car is traveling. It is to provide an emergency call device for an elevator.

[0006]

In order to achieve this object, the present invention provides an in-car intercom which is installed in an elevator car and has a call button, and an in-car intercom and a communication line. In an emergency call device of an elevator equipped with a monitoring call device connected via a call, when the car stops at the nearest floor in response to a call signal output from the call button and the door is opened, The structure is provided with connection blocking means for blocking the connection between the in-car communication device and the monitoring communication device.

[0007]

Since the present invention is configured as described above, when the call button of the intercom in the car is operated while the car is running, the call signal output from the call button is output according to the call signal. The car is stopped at the nearest floor, that is, the floor closest to the floor when the call signal is output, and the door is opened. At this time, if the door does not open due to a failure, the in-car communication device and the monitoring communication device are connected, while if the access door opens, the in-car communication device is connected by the connection blocking means. The connection between the communication device and the monitoring telephone is blocked. In this way, when the call button is operated while the car is running, it is judged whether it is a malfunction or a prank,
Since the connection processing between the in-car cage communication device and the monitoring communication device is performed, it is possible to prevent the in-car communication device and the monitoring communication device from being connected to each other by mischief while the car is traveling.
