PURPOSE: Folding type stairs are provided to facilitate keeping or transportation as volume can be reduced when not in use and to enable an operator to steadily move up and down. CONSTITUTION: Folding type stairs comprise a support frame(110), a movable frame(120), a step(130), and a link assembly(140). A pair of support members(111) are separated from each other and are formed in the support frame. A pair of movable members(121) are coupled with the support members in the movable frame. The link assembly connects the steps to the support frame or the movable frame. |
