In the state in which the door opening time is controlled by the extension means and the second extension means, both the first ultrasonic detector and the second ultrasonic detector do not detect passengers. And a second door closing means for closing the door when the door is opened.

[Action]

According to the present invention, when a person with a disability in a wheelchair gets into a car, he / she operates a switch for a person with a disability at a hall, and when the first ultrasonic detector detects a passenger, that is, a person with a disability in a wheelchair, the door is opened. The first extension means for extending the opening time is activated. As a result, the door opening time is set to a normal door opening time for persons with disabilities, for example, a door opening time longer than 15 seconds. Therefore, even if a disabled person in a wheelchair takes more than 15 seconds to get into the car, the door will not close. Then, when the disabled person in the wheelchair gets into the car, the second ultrasonic detector detects it, and the first ultrasonic detector stops sensing the disabled person in the wheelchair, the door is closed by the first closing means. Is closed.

A person with disabilities operates a switch for people with disabilities in the car,
The car ascends / descends to a predetermined destination floor, landes on the predetermined destination floor, and the door opens. In this state, the second ultrasonic detector detects a passenger with a disability in a wheelchair, so the second extension means is activated and the door opening time is longer than the normal elevator door opening time of 15 seconds. Even long door opening times are set. Therefore, even at this time, even if the disabled person in the wheelchair takes more than 15 seconds to get into the car, the door does not close. When the disabled person in the wheelchair gets off the car from the car and both the first ultrasonic detector and the second ultrasonic detector no longer detect the disabled passenger, the door is closed by the second closing means. To be closed.

In this way, it is possible to prevent the wheelchair of a disabled person from being caught in the door when the disabled person in the wheelchair gets in or out of the car.
