发明名称 Double ladder
摘要 This double ladder has two pairs of uprights which are pivotable towards one another and has at least two steps which are horizontal in work position. The steps are connected via a connecting rod and can be pivoted into a hanging rest position. Also provided is a guide part which is mounted displaceably in a guide path. The guide part is in this case arranged on one pair of uprights. The guide path, in which the guide part engages, is designed on the step connecting the two pairs of uprights, essentially in its plane.
