Abstract (en)

[origin: EP1449800A1] An emergency elevator stopping apparatus provided on an elevator car 1 and adapted to stop the elevator car 1 by pressing a guide rail 2 along which the elevator car 1 is guided, including: an elliptic roller 15 disposed rotatably in the vicinity of the guide rail 2, and having a smaller diameter shorter than a distance between the guide rail 2 and a rotary shaft 15a and a larger diameter longer than the same distance, and a lever 13 adapted to set the direction in which the guide rail 2 extends and that in which the larger diameter of the roller 15 extends, substantially parallel to each other while the elevator car 1 moves at a speed not higher than a predetermined level, and turn the roller 15 when the elevator car 1 moves at a speed in excess of a predetermined level, and thereby cause the roller 15 to press the guide rail 2. <IMAGE>
