Abstract (en)
[origin: EP0410774A2] An elevator system is provided having a car in a hoistway. A pair of linked profiles (3) are pivotally connected to the car door (4). When the car stops at a floor, the profiles lie between rollers (6, 7) which are provided on the hoistway door (5) at each floor and which cooperate with the hoistway door lock shaft 1a. The profiles (3) are biased by a spring (10) (see Fig. 2) into an expanded condition in which they are level with one another and push against the hoistway door rollers (6, 7) to tilt the latch (1a) open. However when the car door (4) is closed, a cam roller (8) attached to one of the profiles (3) moves along a cam track (9) and forces the profiles (3) together to lock the lock 1. When the car door (4) opens, the cam roller (8) moves out of the cam track (9), so that the profiles (3) expand, and push the hoistway rollers (6, 7) which open the lock 1. The profiles (3) remain in engagement with said rollers (6, 7) so that the movement of the car door (4) is transmitted to the hoistway door (5) during opening and closing of the doors (4, 5).
