An abnormal opening detection device for an elevator door, characterized in that when the photoelectric device does not receive reflected light for a predetermined period of time, it is detected as an abnormal opening of the driven door on the landing side .

Claims

[Scope of utility model registration request]

A device for detecting an abnormal opening of a drive door disposed on each of the landing side and car side of an elevator and a driven door linked to the drive door, the device comprising: a reflection of a constant width extending over the entire length of the driven door in the longitudinal direction; A mirror is disposed, and a reflector having substantially the same width as the reflector is disposed on the hoistway wall as an extension of the reflector in the closed position, and the reflector is opposite to the reflector. A photoelectric device that emits light and receives the reflected light is disposed at the top and bottom of the car, respectively, and is configured to operate when the car goes up and down. An abnormal opening detection device for an elevator door, characterized in that when no light is received for a predetermined period of time, it is detected as an abnormal opening of the driven door on the car side.
