도어 가이드실에 설치되어 승강장 도어가 도어 가이드실로부터 이탈되는 것을 방지하는 엘리베이터용 이탈방지장치에 관한 것으로, 중심부가 절곡된 평판 형상의 고리로 도어 가이드실의 실홈의 길이방향과 수직한 방향으로 연장되는 승강장 훅, 및 승강장 도어의 하단 중앙에 부착되고 “[”의 단면을 갖는 고리로서 승강장 훅이 끼워지는 끼움홈을 갖는 도어훅을 포함하고, 승강장 훅은 도어 가이드실에서 승강장 도어가 완전히 닫혔을 때 도어훅과 대응되는 위치에 설치되고, 승강장 도어가 완전히 닫혔을 때 승강장 훅이 도어훅의 끼움홈에 끼워짐에 따라 승강장 훅에 승강장의 바닥과 수평인 방향의 외력이 가해지더라도 승강장 도어가 도어 가이드실로부터 이탈되는 것을 방지할 수 있다.

    The present invention relates to a derailing prevention apparatus for an elevator installed in a door guide room to prevent a landing door from being derailed from the door guide room. The derailing prevention apparatus includes: a landing hook which extends in a direction perpendicular to the longitudinal direction of a thread groove of the door guide room with a flat-shaped ring with a bent center; and a door hook which is attached to the lower center of the landing door and has a fitting groove into which the landing hook is inserted as a ring with a cross-section of a C-shape. The landing hook is installed at the position corresponding to the door hook when the landing door is completely closed in the door guide room. When the landing door is completely closed, the landing hook is inserted into the fitting groove of the door hook, so even if an external force in the horizontal direction with the floor of the elevator is applied to the landing hook, thereby preventing the landing door from being separated from the door guide room.
