Abstract

높은 곳에 작업을 행하거나 고층으로 이동하기 위해 사용되는 접이식 계단이 개시된다. 지지 프레임은 한 쌍의 지지 부재들이 서로 이격되고 하단에서 서로 연결된다. 가동 프레임은 한 쌍의 가동 부재들이 지지 부재들에 각각 승강 가능하게 끼움 결합하고 상단에서 서로 연결된다. 발판들은 지지 부재들 간의 이격된 공간과 가동 부재들 간의 이격된 공간에서 상하로 배열된다. 링크 조립체는 발판들을 지지 프레임 또는 가동 프레임에 연결하며, 가동 프레임이 지지 프레임에 대해 승강하는 과정에서 발판들이 연동되어 펼쳐지거나 접히도록 신축 동작한다. 이에 따라, 미사용시에 부피가 줄어들 수 있어 보관 또는 운반이 편리할 수 있으며, 장시간 작업시에도 안정된 자세에서 편하게 작업할 수 있고 안정되게 오르내릴 수 있다.
