Foldable ladder that can be assembled with work platform
The present invention relates to a foldable ladder allowed to be assembled as a work platform, the foldable ladder comprising: a leg part including a pair of vertical members arranged side by side and having a plurality of insertion holes formed through side surfaces thereof, a plurality of footplate members connecting the vertical members to each other, and a perforated plate covering one side surface of each of the vertical members and the footplate members; an auxiliary leg part including vertical bars, which have a U-shaped cross-sectional surface to have a space part formed therein, are arranged to face each other, and have a through-hole formed through the exterior side of each upper end thereof, and a plurality of transverse bars installed to be aligned on the outer surface of one side of each of the vertical bars, wherein the auxiliary leg part adjusts the height of the leg part while sliding on the exterior side of the vertical members inserted into the space parts; a position fixing means fixed to an upper part of the auxiliary leg and fixing the height of the leg part while passing through the through-holes (212) to be selectively inserted into the insertion holes; and a hinge part coupled to the upper ends of the pair of leg parts and allowing the leg parts to be axially folded or unfolded. The foldable ladder is assembled to be deformed into a work platform having footplates in order to perform a work requiring safety, thereby allowing a user to effectively use a space.
본 발명은 나란하게 배치되며 측면에 삽입공을 다수 형성한 한 쌍의 수직부재와 수직부재의 사이를 연결하는 다수의 발판부재와 수직부재와 발판부재의 한쪽면을 덮는 타공판을 포함하는 다리부와, 내부에 공간부가 형성되도록 단면이 'JPEG112019051299190-pat00009.jpg44'자 형상으로 형성되어 마주보고 배치되며 상단 외측에 통공이 형성된 수직바와, 수직바의 한쪽 외측면에 정렬설치된 다수의 가로바를 포함하여 상기 공간부에 수직부재가 삽입되어 수직부재의 외측을 슬라이딩하며 높이를 조절하는 보조다리부와, 상기 보조다리의 상부에 고정되어 상기 통공(212)을 관통해 수직부재의 삽입공에 선택적으로 삽입되면서 다리부의 높이를 고정하는 위치고정수단과, 한 쌍의 다리부의 상단에 결합되어 다리부가 축으로 접혀지거나 펼쳐지는 힌지부를 포함하는 작업대로 조립 가능한 접이식 사다리에 관한 것이다.
