摘要： The invention relates to a collapsible ladder (1) having hollow ladder bars (2, 3) and ladder pins (4). The bars are divided into sections, which are telescopically inserted into each other and which in pairs at their top are connected to each other via a ladder pin, ladder sections, positioned above each other, being formed. The ends of the ladder pins (4) each houses its retaining mechanism (6), which via a locking pin (8) is locked against the lower portion of a ladder section, positioned above, in a separated or in a activated position of two such sections, arranged after each other, and which is releasable in order to allow an insertion of said ladder section, positioned above. According to the invention said retaining mechanisms can be actuated outside the space between the ladder pins (4), preferably on the front of the ladder, and are designed to be released in each section manually and individually, Also, the locking pins (8) project in their locking positions into the hollow space (9) in the locked bar section in order to in this area constitute safety units, designed to prevent the bar portions from passing by to the bar section, which follows after said bar section, positioned above.
