Ladder e.g. foldable climbing ladder, has ladder parts connected with each other by pivoting joints such that usage position of ladder is set by holder based on non-usage position to automatically form usage position and lock joints

摘要

The ladder (100) has pivoting joints (202A, 202A`) with ladder parts (104A-104C), which are connected with each other in a pivotable manner by the joints. The ladder parts have beams (102, 102`) running parallel to each other, where the beams are connected with each other by rungs (106A-106C). The ladder parts are connected with each other by the joints such that a usage position of the ladder is set by a bare holder based on a non-usage position to automatically form the usage position and automatically lock the joints. The joints are arranged between the beams.
