The present invention relates to a platform door release device for an elevator. An inner door hook and an outer door hook are coupled to the inner and outer lower ends of the platform door, and a platform fixed hook and a platform rotation hook are installed at positions corresponding to the inner door hook and the outer door hook when the platform door is completely closed. When the platform door is completely closed, as the inner door hook and outer door hook combined on both sides of the platform door, the platform fixed hook and the platform rotation hook are combined, respectively, even if a strong external force is applied to any part of the platform door which is closed, the platform door can be efficiently prevented from released from a door guide chamber.

    본 발명은 엘리베이터용 승강장 도어 이탈장치에 관한 것으로서, 내측도어훅 및 외측도어훅이 승강장 도어의 내측 및 외측 하단부에 결합되고, 승강장 도어가 완전히 닫혀있을 때 내측도어훅 및 외측도어훅에 대응되는 위치에 승장강 고정훅 및 승강장 회전훅이 각각 설치됨으로써 승강장 도어가 완전히 닫혀있을 때 승강장 도어의 양측에 결합된 내측도어훅 및 외측도어훅과 승강장 고정훅 및 승강장 회전훅이 각각 결합됨에 따라 닫혀있는 승강장 도어의 임의의 부분에 강한 외력이 가해지더라도 승강장 도어가 도어 가이드실로부터 이탈되는 것을 효과적으로 방지할 수 있다.
