Embodiment Construction

[0026] figure 1 Different views of the invention are shown in the first state. A ladder 1 can be seen, which includes a first upright member 2 equipped with a plurality of steps 3, the first upright member being hinged to a second upright member 5 with one end 4 in the longitudinal direction On the end in the longitudinal direction, the second upright member 5 is equipped with at least one detachable and closable eyelet 6 for directly tightening the ladder 1 rotatably around the vertically extending tube 7 of a scaffold upright member 8 solid. This figure also shows a scaffold 9 comprising a system with a plurality of scaffold erectors 10, at least one vertically extending tubular section 7 with a substantially circular cross-section 11, and erected by these scaffolds At least one platform 12 carried by the piece 10, the platform forming a working surface, characterized by a ladder according to one of the preceding claims, wherein the at least one eyelet is around the tube wit...

Abstract

The present application relates to a ladder, comprising a first upright, provided with rungs, hingedly connected at one end in the longitudinal direction to the end in the longitudinal direction of a second upright, wherein the second upright is provided with at least one eye which can be removably closed for the rotatable fastening of the ladder directly about a vertically extending tubing of a scaffold upright, as well as a scaffolding, comprising a system of scaffold uprights, there being at least one vertically extending tubing part with an essentially round cross section and at least one platform carried by the scaffold uprights and forming a work surface provided with such a ladder.

Description

Technical field [0001] The invention relates to a ladder, in particular a ladder for fastening to a scaffold. Such ladders are also called stairs or landing ladders and are themselves known from, for example, U.S. Patent US3997024 and U.S. Patent No. 4,807,719, and they are used to achieve climbing to scaffolding and promote climbing in a specified manner, namely from the side Scaffolding. Background technique [0002] However, the prior art ladder has several disadvantages. First of all, they are not universally applicable to any given scaffold, but a scaffold must be equipped with a special fastening device for them. [0003] In addition, the known fastening design increases the width of the scaffolding, which is a disadvantage when moving such scaffolding, especially when moving through narrow openings, such as door frames. [0004] Therefore, an object of the present invention is to create a ladder used on scaffolding without the above-mentioned disadvantages and being able to...
