Definitions
- the ladder which is the subject of the present patent application is manufactured according to a new technique and with the aim of facilitating its transport, its handling and its storage, thanks to a new design.
- the ladder is made up of two uprights 1 and 1 ', linked together by transverse bars 2, in such a way that it is possible to press the uprights 1 and one against the other to reduce its size.
- Figure 1 the thickness of the scale is equal to the thickness of the two uprights 1 and 1 '.
- bars 2 are therefore mobile, so as to be able to either place the uprights 1 and one against the other for storage and transport, or move aside the uprights 1 and 1 'for using the ladder. .
- the bars 2 are horizontal ( Figure 2), in the storage and transport position, they are slightly oblique ( Figure 3).
- Figure 2 When deploying the ladder, the upright 1 'leaves its resting place to touch the ground; in this deployment phase, the bars 2 are horizontal, thanks to axes 3 which connect them to the uprights 1 and 1 '; the spacing of the uprights 1 and 1 'then corresponds to the length of the bars.
- each end of the bars 2 are held by a riveted pin 4 '.
- Each end of the bars 2 is provided with a tip with rounded head 5 to ensure mobility and to strengthen the solidity.
- One of the bars 2 ' is full and has at one of its ends 2 1 ' a locking device ( Figure 4) to keep the ladder open safely.
- This device is composed of a steel axis 6, a spring 7 and two pushers 8 screwed onto the axis 6.
- the upright 1 is provided at the bottom with a tube end 11 whose upper part is partially bevelled, while on the upright 1 'an identical element 11' is fixed on its upper part.
