Abstract (en)
[origin: EP0498247A1] Using this device, noise and vibration which occur during actuation and unlatching of a shaft door (1) which is moved by a driven car door (2) can be largely prevented. To this end, a first coupling element (3) which is mounted on the shaft door (1) and a second coupling element (4) which is mounted on the car door (2) are constructed as magnets and are arranged in such a manner that a north pole (N) of the first coupling element (3) is opposite a north pole (N) of the second coupling element (4), and a south pole (S) of the first coupling element (3) is opposite a south pole (5) of the second coupling element (4), separated by an air gap in the movement direction of the doors. Provided on a latching element of the shaft door (1) is a further magnet whose one pole is located opposite a similar pole of the second coupling element (4), with an air gap, in the movement direction of the doors. When a car stops at a floor, the repulsion forces of the magnets initially unlatch the shaft door (1) without being touched, and then move without being touched when the car door (2) opens. <IMAGE>
