Description

  The present invention relates to an emergency communication device for an elevator.

  Under the Building Standards Law, it is mandatory to install an emergency contact device as part of the elevator safety device. That is, as a general rule, emergency contact devices are installed in all elevators. And the conventional emergency contact apparatus is limited to the extension call in the elevator car, the elevator machine room, and the manager room. However, only when a contract is concluded with the elevator maintenance management company, it is configured such that an outside line call can be made only with the maintenance management company. In addition, some old elevators have a simple configuration in which a buzzer installed in a manager's room sounds only when a notification button in a car is pressed.

  In such emergency contact devices, in the event of an emergency such as an earthquake, fire or water damage, if a confinement failure occurs in the elevator, the rescue of passengers in the car is the only way unless a contract is made with the elevator maintenance management company. It is entrusted only to the building manager. For this reason, there is a problem that the rescue is delayed if the manager takes off the seat of the management room. Even if a contract is made with an elevator maintenance management company, if a confinement failure occurs frequently due to a large-scale natural disaster, the dispatch of the maintenance management company may be delayed. At that time, there is a problem that it is not possible to directly contact a rescue unit such as a fire department.

  Therefore, an emergency contact device in which an external telephone or a mobile phone is installed as a communication device has been proposed (for example, see Patent Document 1).

When the power supply of the normal power supply 23 is cut off, the electronic lock control coil 26 is dropped out. That is, the lock device 9 is unlocked. For this reason, the passenger can take out the internal communication device 5. That is, the passenger can talk with the external communication device using the internal communication device 5.

  According to Embodiment 1 demonstrated above, the passenger in a cage | basket cannot open the door 7 normally. For this reason, mischief and theft of the internal communication device 5 can be prevented. Further, the film 8 and the display lamp 13 can inform the car that the open / close door 7 is released from maintaining the closed state when an emergency is detected. For this reason, it is possible to prompt the passenger to use the internal communication device 5 promptly. Thereby, a passenger's safety and convenience can be improved.

  Furthermore, the internal communication device 5 includes a mobile phone terminal that performs wireless communication. This eliminates the need for wiring for transmitting and receiving information relating to the communication between the inside and outside of the car. In addition, the internal communication device 5 can be used without concluding a special contract with an elevator maintenance company. For this reason, even when a confinement failure frequently occurs due to a large-scale natural disaster, the passenger can directly contact a rescue unit such as a fire department.

  In addition, by using a mobile phone instead of an external telephone, it is possible to reduce initial installation costs such as telephone line installation costs, line usage fees, and maintenance costs. Further, a charging device 11 that supports the internal communication device 5 and charges the rechargeable battery 6 is provided in normal times. For this reason, simply by installing a mobile phone terminal or the like as the internal communication device 5, driving power is ensured even in an emergency, and it is possible to communicate with the external communication device reliably.
