  • Patent number: 5411117
    Abstract: A safety device arrangement for stopping the downward drift of an elevator car (1) has a controllable arrester (10) mounted on the supporting frame (7) of an elevator car. The arrangement is provided with latches (20), and for each latch a stop block (26) is immovably mounted in the elevator shaft (3). The arrangement comprises buffer elements (13) placed between the arrester (10) and the supporting frame (7) of the elevator car. When the elevator car rests on latches (20) engaged by stop blocks (26), the resulting supporting forces are passed between the car frame (7) and the arrester (10) substantially only through the buffer elements (13).
