The present invention relates to an elevator door separation prevention device, which is applied to a door of an elevator for moving a person or cargo up and down to increase the stopping power against the impact load generated at the front surface to prevent the unauthorized separation of the door and the opening of a hoist way, thereby preventing fall accidents. The elevator door separation prevention device comprises: a door frame installed on the floor of an elevator opening connecting an elevator path, along which an elevator moves, to an interior space; elevator doors opened and closed by being close to and spaced apart from each other with respect to the center of the elevator opening; and a separation prevention means configured to lock the elevator doors while the elevator opening is closed as the elevator doors approach, and generate a support pressure against an impact applied from a front surface. The separation prevention means includes: a safety bar embedded in the door frame to axially move about a rotational shaft, and having a locking piece formed on one side end thereof, which has a length upward; a locking bracket provided on the elevator door and formed with a locking space, which is locked and coupled as the locking piece is fitted while the elevator door is disposed to close the elevator opening; and a pressing bracket provided on the elevator door and having a pressing bar configured to press the locking piece to move up by pressing and axially rotating a pressing piece disposed at a location symmetric to the locking piece on the safety bar while the elevator door is disposed to close the elevator opening.

    본 발명은, 도어의 무단 이탈을 방지하여 승강로가 개방되는 것을 방지함으로써, 추락사고 등을 예방하도록; 승강기가 이동운동하는 승강통로와 실내공간을 연결하는 승강개구의 바닥에 시설되는 도어문틀과; 상기 승강개구의 중앙을 중심으로 서로 근접 및 이격되어 개폐하는 승강도어들과; 상기 승강도어들의 근접에 따라 상기 승강개구가 폐쇄되는 중에 상기 승강도어들을 잠금하고 전면에서 인가되는 충격에 대하여 지지압을 형성하는 이탈방지수단;을 포함하는 엘리베이터 도어이탈방지장치에 있어서; 상기 이탈방지수단은, 회전축을 중심으로 축회전운동가능하게 상기 도어문틀에 내설되며 일측단에 상부로 길이를 가지면서 형성되는 잠금편이 연장구비된 안전바와; 상기 승강도어에 구비되며 상기 승강개구가 폐쇄되도록 상기 승강도어가 배치되는 중에 상기 잠금편이 끼움되면서 잠금결합되는 잠금공간이 형성된 잠금브라켓과; 상기 승강도어에 구비되며 상기 승강개구가 폐쇄되도록 상기 승강도어가 배치되는 중에 상기 안전바에서 상기 잠금편과 대칭되는 위치에 배치된 가압편을 가압하여 축회전시키어 상기 잠금편을 상승시키도록 가압하는 가압바가 구비된 가압브라켓;을 포함하는 것을 특징으로 하는 엘리베이터 도어이탈방지장치를 제공한다.
