ABSTRACT:
A magnetic coupling device is disposed on an elevator car door in a position to engage a magnetic vane disposed on a hoistway door which is to be opened in unison with the car door. The magnetic coupling unit may comprise either an electromagnet or a permanent magnet and has spring loaded rollers disposed above and below it so as to control the initial force of engagement between the elevator car door and the hoistway door, for smoother door opening operation.
