Abstract

The ladder has an automatic shifting unit for shifting support legs (6). The unit has a spacer arm (22) placed below a foldable platform (4). The arm has an end articulated on a pivot (23), and another end articulated on a collar (8) that is assembled on the corresponding leg. A lateral tie rod (10) has an end connected to the collar by a hinge (9), and another end connected to posts (2) by a hinge (12). The arm and the rod form two sides of a triangle. Third side of the triangle is formed between the pivot and the hinge (12) and modifies the position of the collar on the leg.
