Abstract

The ladder has side parts (2) arranged between its opposing longitudinal edges, between which transversal runs (3) extend. To facilitate a comfortable adjustment of their position in relation to the roof slope, the rungs are pivotable around axes (9,10) which are transversal to the side parts (2). - The rungs are connected with at least one longitudinal adjustment part which through longitudinal displacement causes them all to pivot. Pref., each side part comprises lower (7) and upper (6) longitudinal rods, the upper rod having the function of the adjustment part.
