The present invention provides an interlocking device provided on a car door of a freight elevator to interlock a hall door. According to the present invention, the interlocking device comprises a car frame (100A) supported by a car door of an elevator; a hall frame (100B) capable of being engaged with a structure provided on the back surface of a hall door to be interlocked with the hall door of the elevator; and an interlocking link body (La) provided between the car frame and the hall frame and expandable toward the hall frame from the fixed car frame. According to the present invention, the interlocking link body (La) comprises a plurality of arms capable of folding and unfolding; a folding means unfolding the arm into an unfolded state to engage the hall frame with the hall door; and an unfolding means folding the arm into a folding state in which the hall fame is adjacent to the car frame. The folding and unfolding of the interlocking link body use an elastic member, such as a spring, and a solenoid. According to the present invention, durability can be maintained sufficiently even in long-term use.

    본 발명은, 화물용 승강기의 카도어에 설치되어 홀도어를 연동시키기 위한 연동장치를 제안하고 있다. 본 발명 연동장치는, 승강기의 카도어에 지지되는 카프레임(100A)과; 승강기의 홀도어와 연동할 수 있도록, 홀도어 이면에 설치되는 구조물과 결합될 수 있는 홀프레임(100B): 그리고 상기 카프레임과 홀프레임 사이에 설치되고, 고정된 카프레임에 대하여 홀프레임 측으로 신장되거나 수축 가능한 연동링크체(La)로 구성된다. 본 발명의 연동링크체(La)는, 폴딩 및 언폴딩 가능한 다수의 아암과, 홀프레임이 홀도어에 결합되도록 언폴딩 상태로 아암을 펼치기 위한 폴딩수단, 그리고 홀프레임이 카프레임에 인접한 폴딩 상태로 아암을 접기 위한 언폴딩수단으로 구성된다. 연동링크체의 폴딩 및 언폴딩은, 스프링과 같은 탄성부재 및 솔레노이드를 이용한다.
