Abstract (en)
[origin: US6543579B2] A length-adjustable ladder functioning as a telescopic lean-to ladder, a free-standing stepladder, and as a platform is described. The ladder includes stringers, ladder rungs fastened between the stringers, and supports connected to the stringers. The supports can be length-adjusted in a stepless manner. The supports can be swung in and arrested on the outer longitudinal sides of the stringers. A floor board assembly formed of two panel halves corresponding to a length of the ladder and has hinges is disposed on the two panel halves. The two panel halves each have a longitudinal side fastened, in an articulated manner on the ladder rungs by the hinges. Arresting elements are provided. Each of the arresting elements run through one of the two panel halves. The two panel halves are movable into a swung-up panel position wherein the two panel halves are arrested by the arresting elements.
