  • Publication number: 20130175119
    Abstract: A collapsible ladder (100), comprises a number of tube portions (210, 220, 310, 320) having various diameters and being telescopically insertable into one another. The upper end of a first tube portion (210, 310) is connected to one end of a ladder step (230, 330) and the other end of the ladder step (230, 330) is fastened to an upper end of a second tube portion (220, 320) having the same diameter as the first tube portion (210, 310). The first (210, 310) and second tube portions (220, 320) and the ladder step (230, 330) form a ladder section (200, 300), the tube sections of which being insertable into an adjacent ladder section comprising tube portions having a larger diameter, wherein the ladder sections may be mutually interlocked by interaction between pins (280) located in the ladder steps (230, 330) and openings provided in the tube portions of a neighboring ladder section.
