The present invention relates to an opening/closing apparatus for a multi-stage elevator door. With the present invention, the multi-stage door can be opened and closed with speed and stability by a driving method based on a simple structure. In addition, the present invention is structurally compact and thus convenience can be provided in terms of manufacturing and maintenance. The present invention is provided so as to open and close doors (11 to 14) of an elevator car (10) in line with floor doors on building floors. The present invention is operated such that the doors (11 to 14) overlap forward and backward during opening and is driven such that the doors (11 to 14) are continuously unfolded during closing. A drive unit (31) includes pulleys or sprockets (37 to 40) coupled onto a drive shaft (35) such that door belts (41 to 44) mesh. The pulleys or sprockets (37 to 40) are mounted in multiple stages on the single drive shaft (35). The pulleys or sprockets (37 to 40) have different diameters, different numbers of gear grooves, or different numbers of teeth. As a result, the traveling distances or speeds of the doors (11 to 14) are different.

    본 발명은 간단한 구조의 구동방식에 의해 다단도어를 개폐작동을 신속하면서도 안정적으로 행할 수 있을 뿐만 아니라 컴팩트한 구조에 따른 제작 및 유지보수 상의 편리함을 제공할 수 있는 엘리베이터의 다단도어 개폐장치에 관한 것이다. 본 발명에 따르면, 건물의 각 층에 구비된 층별도어를 연동하여 승강카(10)의 도어(11~14)를 개폐시키도록 구비되되, 개방시에 복수의 도어(11~14)가 전후로 겹쳐지도록 작동시키거나 닫힘시에 복수의 도어(11~14)가 연속적으로 펼쳐지도록 구동하는 엘리베이터의 다단도어 개폐장치에 있어서; 구동유닛(31)은 구동축(35) 상에 결합되어 각 도어벨트(41~44)가 맞물리도록 된 풀리 또는 스프라켓(37~40)을 포함하되; 상기 풀리 또는 스프라켓(37~40)은 하나의 구동축(35) 상에 복수개가 다단으로 장착되되, 상기 각 풀리나 스프라켓(37~40)은 직경과 기어홈수 또는 잇수를 달리하여 상기 각 도어(11~14)의 주행거리나 속도를 달리하도록 된 엘리베이터의 다단도어 개폐장치가 제공된다.
