0002

[Prior Art] When a plurality of elevators are installed and group control is performed by group management, an elevator car position display device (indicator) for each elevator is not provided at the elevator landing of each floor, and an entrance/exit frame is provided for each elevator. A hall lantern is installed in the elevator section, and only the hall lantern of the elevator that responds to a call at the hall lights up and is displayed to the users. In this case, it is not displayed which floor the car is traveling on, including other elevators.

[0003] For this reason, even if the elevator stops due to a power outage or a malfunction, it is unclear at which floor the elevator has stopped. Therefore, in order to repair the malfunction or rescue the trapped passengers, maintenance personnel had to go to the machine room, check which floor the train was stopped on, and then go to that floor and carry out the rescue work.

[Problem to be Solved by the Invention] However, if the rescue operation is started after going to the machine room and confirming the floor where the car is stopped, it takes a long time and increases the anxiety of the passengers. In addition, in order to hasten the rescue of the trapped passengers,
In some cases, the hall door is opened using the unlock key without checking the floor where the hall door is stopped, but if the car is not stopped near the floor where the hall door is opened, the hoistway becomes a deep hole and the inside of the hall door is opened. There is a risk of falling.

The present invention was made in view of the above-mentioned circumstances, and its purpose is to detect the stopping position of the car without having to go to the machine room in the event of a failure in an elevator that does not have an indicator and only has a hall lantern. Elevator elevators that can be quickly and easily checked at the landing, quickly relieve passengers' anxiety by quickly rescuing passengers trapped in the car, and prevent the danger of falling into the hoistway. The purpose of the present invention is to provide a car position display device.

[0006]

[Means for Solving the Problems] The present invention provides a portable car position indicator equipped with a display section and a selection switch that outputs outputs from a car sorting circuit and a car position display discrimination matrix circuit provided in an elevator control device. , the car is arbitrarily input via a connector at the landing of each floor of the elevator, the car is selected on a portable car position display, and the stop position is displayed on the display.

[0007]

[Function] At the landing of each floor of the elevator, you can select a car and check the stopping position of the selected car using the portable car position display, so you can quickly unlock the hall door of the nearest floor using the unlock key. Locked and trapped passengers can be rescued within a short period of time.
