Abstract (en)

[origin: EP1939126A1] A door device for an elevator includes: an elevator door having first and second doors; first and second door driving devices having first and second rotary shafts, respectively; a first power transmission mechanism for moving the first door in response to rotation of the first rotary shaft; a second power transmission mechanism for moving the second door in response to rotation of the second rotary shaft; a position detector for generating a signal corresponding to the rotation of the first rotary shaft; and a door control device for controlling the second door driving device based on information from the position detector such that the rotation of the second rotary shaft follows the rotation of the first rotary shaft. With this structure, movement speeds of the first and second doors are synchronized according to information from the single position detector.
