Emergency / cargo elevator operating status display device located outside the fire door

The present invention relates to a device for displaying the operating status of an emergency/freight elevator provided outside a fire door, and more particularly, it recognizes the operating status by shooting an operating status display image of an emergency/freight elevator installed inside an opening/closing space dividing wall. It is related to a technology that enables the customer to check the operation status display information of the elevator from the outside of the opening/closing space partition wall without opening and closing the corresponding door by transmitting and outputting it to a third operating status display device installed outside the opening/closing space dividing wall. will be.

In the case of emergency/freight elevators, fire doors are installed in the opening and closing space to protect passengers and facilities from fire in accordance with the evacuation facility regulations stipulated in Article 10 of the Fire Protection Act and Article 49 of the Building Act.

As such, since the emergency/freight elevator is installed inside the firewall, the passenger must open and close the fire door to check the operating status of the elevator, such as the location (floor) and operating direction (up or down), which causes inconvenience in using the elevator.

In addition, in some buildings, elevators are operated with fire doors that should be closed at all times, thereby threatening the safety of passengers in case of fire or emergency.

In order to solve this inconvenience, an increasing number of buildings have recently installed a separate operation status display device outside the firewall, that is, outside the opening and closing place. After receiving the driving status information from the device by wire, it is displayed.

In this process, it is necessary to drill the opening/closing space dividing wall or fire door to wire the operation status display information transmission line. There are problems such as violating the facility law or the building law. This problem is repeated on every floor for all floors of the building.

As mentioned above, in order to transmit the operating status information to the operating status display device installed outside the partition wall, it is necessary to connect a wire to the existing elevator circuit installed in the building. It is desirable to construct the elevator at the time the building was completed.

However, since most of the construction work to install the display device on the outside of the dividing wall of the opening and closing space has already been completed and the construction is carried out after each household or tenants have moved in, it is difficult for elevator installation companies to cooperate with the construction and lack of expertise. A lack of a third party or maintenance company may cause safety problems as construction is performed.

In addition, when an additional device is installed by extending the wire from the existing device in a wired manner, it is not easy to identify the responsible person in case of abnormal operation of the elevator itself, a fire, or other emergency, and the possibility of occurrence of problems increases.

Accordingly, the applicant of the present applicant records the operation status information of the emergency/freight elevator installed inside the opening/closing space partitioning wall as an image, recognizes it, transmits it wirelessly, and outputs it through a separate display device installed on the outside of the opening/closing space partition wall. The present study proposes a display device that can check the elevator operation status information from the outside of the opening and closing space dividing wall without opening and closing the fire door.
