Abstract
The invention relates to an elevator door opening device designed for opening the car doors and the landing doors. The door opening device comprises a power means and a door coupling apparatus for opening and closing the car and landing doors essentially simultaneously. According to the invention, the door coupling apparatus engages both the car door and the landing door when the car is at a landing, in such manner that its travel during the opening and closing motion of the doors is essentially shorter than the travel of the doors, and that the door coupling apparatus is located outside the area delimited by the landing doorway.
