The present invention relates to a roller type apparatus for locking car doors of an elevator. When car doors come closer to each other, a locking pin enters a locking groove and a restraint arm presses the locking pin so that the locking pin does not unlink from the locking groove to prevent the car doors from opening. When the car doors are far from each other, the restraint arm is far from the locking pin and the locking pin unlinks from the locking groove so that the car doors open. Therefore, it is possible to prevent the car doors from opening due to an abnormal operation and to improve stability of an elevator.

    본 발명은 롤러타입의 승강기 카 도어 록킹장치에 관한 것으로, 카 도어가 서로 다가서면 록킹핀이 걸림홈으로 진입함과 아울러 구속암이 록킹핀을 압박하여 걸림홈에서 록킹핀이 빠지지 않도록 함으로서 카 도어가 열리지 않게 하는 반면, 카 도어가 서로 멀어지면 구속암이 록킹핀과 멀어짐과 아울러 걸림홈에서 록킹핀이 빠지며 카 도어가 열리 수 있도록 하여, 비정상적인 작동에 의해 카 도어가 열리지 않도록 단속함으로써 엘리베이터의 안정성을 향상시킬 수 있게 되는 롤러타입의 승강기 카 도어 록킹장치에 관한 것이다.
