摘要： A collapsible ladder (1) having hollow ladder bars (2, 3) and ladder steps (4). Two ladder bars are interconnected at one end by one ladder step to form U-shaped ladder sections, which are telescopically inserted into each other. The upper ends of the ladder bars comprise each a retaining mechanism (6). A locking pin (8) projects into a locking hole in the ladder bar of the adjacent upper ladder section. The retaining mechanisms are actuated outside the space between the ladder steps (4), preferably on the front side of the ladder, and are designed to be released manually and individually. The locking pins (8) project in their locking positions into the hollow space (9) in the locked ladder section in order to provide safety units, designed to prevent the bar portions from passing the locking pin of a bar section.

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.

摘要： A loft ladder assembly 10 is described which comprises a telescopically collapsible ladder 12 in combination with a frame 14 for mounting the ladder 12 within a hatch opening. The frame 14 comprises a mounting bracket 14a to be secured in use to the hatch opening, to which bracket 14a the uppermost section of the ladder 12 is pivotably connected, and a carriage 14b pivotably connected to the mounting bracket 14a for supporting the weight of the ladder 12 in its stowage position and preventing the ladder 12 from extending unintentionally.
