BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator emergency call device, and more particularly to an elevator emergency call device suitable for use when an emergency situation occurs for an inspector inspecting an elevator.

0002

2. Description of the Related Art Accidents in elevators not only cause great inconvenience to people using the elevators, but also may lead to personal injury. For this reason, inspectors are dispatched to elevators from the dispatch company that has jurisdiction over the elevator at predetermined intervals not only when an accident occurs, but also during normal times, and carry out maintenance inspections in the machine room, pit, and above the car. It is supposed to be done. Such maintenance inspections are usually carried out by one person, but if an emergency situation occurs during the inspection work, such as when the inspector becomes physically ill, such as falling down due to feeling unwell, the inspector must go outside by himself. If I didn't contact them, I risked being trapped there for a long time.

Conventionally, as a means of communication in the event of such an emergency, each inspector carries a security buzzer with him or her in case he or she becomes unwell while working in the machinery room and is unable to seek help on his or her own. In this case, the operator operates this buzzer and uses the alarm sound it emits to notify a third party other than the person belonging to the dispatching company of the occurrence of an abnormality, and this third party then contacts the dispatching company to which the inspector belongs. It was hot.

[Problems to be Solved by the Invention] However, with the above-mentioned conventional elevator emergency call system, it is difficult for an inspector to make an emergency call in a relatively closed place such as a pit, or when there is noise near the elevator. When a situation occurs, the inspector is unable to seek help on his own and even if he sounds the buzzer, there is a problem that a third party will not be able to hear the buzzer's alarm sound, and the inspector may leave the alarm unattended for a long time. There was a risk of being exposed. Previously, a third party had to listen to the buzzer's alarm sound and contact the dispatch company.
There was an undeniable feeling that the work was left to someone else, and it was difficult for the dispatch company to know for sure if there was an abnormality in the inspector.

The present invention has been made in view of the actual situation in the prior art, and its purpose is to provide an elevator that can ensure the safety of inspectors without relying on a third party to manage the inspectors. The purpose of this company is to provide an emergency call device.

[0006]

[Means for Solving the Problems] In order to achieve this object, the present invention provides an intercom that is provided inside the passenger car for making calls to the outside, and a telephone line that is connected in response to a calling signal output from the intercom. An emergency call device for an elevator includes a reporting device that connects the intercom to a monitoring unit via a communication device, and receives a wireless communication signal output from a cordless communication device carried by an inspector at at least one of an upper portion and a lower portion of the car. A converting device for converting the wireless communication signal into an intercom call signal is provided between the antenna and the reporting device.

[0007]

[Operation] Since the present invention is constructed as described above, when an emergency situation occurs for an inspector and the inspector is unable to seek help on his own and operates the cordless telephone that he is carrying, the operator responds to this operation. A wireless communication signal is output from the cordless telephone, and this wireless communication signal is received by an antenna provided at at least one of an upper portion and a lower portion of the car. Next, a conversion device provided between the antenna and the notification device converts the wireless communication signal into an intercom call signal, and outputs the signal to the notification device. Accordingly, this reporting device connects the cordless telephone and the monitoring section via a telephone line. Therefore, the operator of the monitoring department communicates with the inspector and takes necessary measures. Thereby, the safety of the inspector can be ensured without relying on a third party to manage the inspector.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the emergency call device for an elevator according to the present invention will be described with reference to the drawings.

FIG. 1 is an overall configuration diagram showing one embodiment of an emergency call device for an elevator according to the present invention, and FIG. 2 is a block diagram of the emergency call device.

The emergency call device of this embodiment shown in FIG. It has a reporting device 5 that connects the intercom 2 to a monitoring unit, for example, a communication device 4a in a monitoring center 4, and the intercom 2 has a terminal block 6 installed on the car 1 and a communication line 7. It is connected to the reporting device 5 via the communication terminal. Further, as shown in FIG. 2, the intercom 2 includes an operation button 2a, and the notification device 5 includes a control device 5a and a communication device 5b.

[0011] Antennas 9a and 9b are provided at the upper and lower parts of the above-mentioned car 1 to receive wireless communication signals output from the cordless intercom 8 carried by the inspector. Between the device 5,
The configuration includes a conversion device 10 that converts the wireless communication signal into an intercom call signal.

[0012] In this embodiment, for example, if an inspector working in the pit P becomes unwell and is unable to seek help on his own, the inspector can Operate the cordless telephone 8. In response to this operation, a calling signal consisting of a wireless communication signal is output from the cordless communication device 8, and this wireless communication signal is received by the antenna 9a provided at the bottom of the car 1. Then,
The wireless communication signal is converted into an intercom call signal by the conversion device 10, and outputted to the reporting device 5 via the terminal block 6 and the call line 7. Accordingly, the reporting device 5 connects the cordless communication device 8 and the monitoring center 4 via the telephone line 3. Therefore, the operator in the monitoring center 4 uses the telephone 4a to talk to the inspector and inquire about the inspector's condition.
It is designed to give instructions for prompt rescue.

[0013] In the embodiment configured as described above, the safety of the inspector can be ensured without relying on a third party to manage the inspector.

[0014]Although this embodiment has been described with reference to the work being carried out in the pit P, wireless communication signals can be received by the antennas 9a and 9b even when the work is being carried out on the car 1, inside the machine room K, etc. Use a cordless phone 8 wherever you can.
Similar actions can be taken by operating . Additionally, antennas 9a and 9b are provided at the top and bottom of the car 1.
Although an example is shown in which two locations are provided, it is not necessarily necessary to provide two locations, and it is possible to select and provide two locations as appropriate. Further, although an example in which the notification device 8 is newly provided is shown, a terminal device or the like provided in an elevator or a remote monitoring device of a building that has recently been installed may be used as the notification device. Although the monitoring unit to which the call signal is reported is the monitoring center 4, the notification may be sent to the dispatch company to which the inspector belongs.

[0015]

[Effects of the Invention] Since the present invention is configured as described above, the safety of the inspector can be ensured without relying on a third party to manage the inspector, so that the inspector can be protected from the occurrence of an emergency situation. This has the effect of being able to respond reliably and therefore improving the safety of inspectors.
