Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an elevator door control device, and particularly to a door control method suitable for an elevator for the handicapped.

[Conventional technology]

Elevators for people with disabilities have longer door opening times than regular elevators, but even so, when getting on or off a car, the door opening time is exceeded and the door hits a wheelchair, which is dangerous.

In addition, related devices of this type include
-43663 is mentioned.

[Problem that the invention seeks to solve]

The above-mentioned conventional technology does not take into account the danger of wheelchairs that cannot be completely boarded and exited even after the door opening time has elapsed, and there is a problem with safety.

SUMMARY OF THE INVENTION An object of the present invention is to provide an elevator door control device that solves the above problems.

[Means for solving problems]

The above object is achieved by installing two ultrasonic detectors inside the car, the first detector detecting the vicinity of the hall door, and the second detector detecting the inside of the car.

[Effect]

When a disabled person gets on the car, the first detector detects it.

The door opening time is extended, and when the second detector detects and the first detector does not detect, the door is closed, and when leaving the car, the door open time is extended when the second detector detects, and the first detector and the first detector do not detect the door. 2 Since the door is closed without detection by the detector, there is no danger of a disabled person getting caught in the door.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

1 is a handicapped person, 2 is a hall operation switch, 3-1 is a car door, 3-2 is a hall door, 4 is a second ultrasonic detector that detects the inside of the heel 6, and 5 is a first ultrasonic detector that detects the vicinity of the hall door. It is a sound wave detector.

When the disabled person 1 operates the hall operation switch 2, the doors 3-1 and 3-2 open, and the first door opens. The second ultrasonic detector is O
NL, the first ultrasonic detector 5 detects the disabled person 1 and extends the door opening time. When the disabled person 1 gets into the heel 6, the second ultrasonic detector 4 detects the disabled person 1, and then the disabled person 1
When the elevator advances into the elevator 6, the first ultrasonic detector 5 detects no detection, and then the doors 3-1, 3-2 close and the elevator starts.

When the elevator reaches the floor and doors 3-1 and 3-2 open, the first door opens.
The second ultrasonic detectors 4 and 5 turn on, and the second ultrasonic detector 4
When it detects a disabled person 1, it extends the door opening time. When the disabled person 1 comes out of the heel 6, the first ultrasonic detector 5 detects it, and the second ultrasonic detector 4 becomes insensitive, and when the disabled person 1 comes out of the heel 6, the first ultrasonic detector 5 detects it. After sensing, the first and second ultrasonic detectors 4 and 5 turn off, and the L door closes and restarts or goes into standby.

〔Effect of the invention〕

According to the present invention, by providing separate detectors for detecting the inside and outside of the car, there is an effect of eliminating the risk of a disabled person getting caught in the door.

Claims (1)

[Claims] 1. In an elevator for the disabled, a first ultrasonic detector having a detection area near the hall door and a second ultrasonic detector having a detection area inside the car are installed in the car, and the disabled person gets on the car. When the car is out of the car, the door open time is extended when the first detector detects it, and when the second detector is detected and the first detector is not detected, the door is closed. When leaving the car, the door is opened when the second detector detects An elevator door control device for a handicapped person, characterized in that the opening time is extended and the door is closed when a first detector and a second detector are not detected.
