Abstract

The invention concerns safety and working comfort on stepladders It comprises 1 a stepladder in which the treads 2 pivot around bars 3 and are maintained in a horizontal working position by arms 4. The object is to retract the treads which cause an obstruction so as to be able to use the stepladder with your back turned to it without the tread above the one being used pressing into your calves.

Description

La présente invention concerne principalement les secabeaux et en particulier un système permettant d'escamoter les marches, de manière à rendre l'utilisation de ce modèle très sûr et très confortable. The present invention mainly relates to the saddles and in particular a system for retracting the steps, so as to make the use of this model very safe and very comfortable.

Aucun dispositif de ce genre n'étant connu actuellement, il est gênant et même dangereux de vouloir se tenir b l'envers sur un escabeaux par exemple pour travailler face à un mur, façon échafaudage. En effet cette position "retournés" est souvent utilisée car elle permet de travailler face à une surface sane avoir l'escabeau devant soi. II est à préciser que cette façon de faire est quelquefois dangerouse et toujours inconfortable, attendu qu'il est obligayeire de se maintenir sur les talons, les jambes légèrement pliées puisque la marche supérieure à celle utilisée rentre dans les mollets. No device of this kind being known at present, it is embarrassing and even dangerous to want to stand upside down on a stepladder for example to work facing a wall, like scaffolding. In fact, this "inverted" position is often used because it allows you to work facing a surface without having the stepladder in front of you. It should be noted that this way of doing things is sometimes dangerous and always uncomfortable, since it is compulsory to keep on your heels, your legs slightly bent since the step higher than that used fits into your calves.

L'escabe@u selon l'invention permet d'éviter ces inconvénients le modèle étant muni de marches escamotables, c'est à dire pouvant se relever dsns l'alignement des jexbes de l'escabeau, en pivotant autour
d'un axe qui peut être un barreau. Elles deviennent alors inutilisables
dans ce cas mais elles ne gênent plus l'utilisateur lorsque celuici est
monté en position retournée, sur une marche inférieure, rabaissée.
The ladder @ u according to the invention makes it possible to avoid these drawbacks since the model is provided with retractable steps, that is to say which can be raised in alignment with the jexbes of the stepladder, by pivoting around
of an axis which can be a bar. They then become unusable
in this case but they no longer bother the user when it is
mounted in the inverted position, on a lower step, lowered.

Ajoutons qu'elles sont relativement larges, donc confortable. Ce système
permet aussi de s'asseoir en utilisant simplement la marche ou reposent
les pieds et celle servant de siège. L'escabeau s'utilise aussi normale
ment c'est à dire à l'endroit.
We should add that they are relatively wide, therefore comfortable. This system
also allows you to sit using just walking or resting
the feet and that serving as seat. The stepladder can also be used normal
that is to say at the place.

Selon une première Variante les marches pivotent autour d'un
axe qui peut être na barreau soudé aux jabes de l'escabeau, elles
peuvent ainsi prendre une position verticale parallèle aux jambes, ou
horisontale une fois rabaissées on position de travail.Dans ce sas elles
sont retenues par deux bras classiques. Précisone que ces bras disposés
de chaque côté des marches ne gênent nullement.
According to a first variant, the steps pivot around a
axis which can be na bar welded to the jabes of the stepladder, they
can thus take a vertical position parallel to the legs, or
horizontal once lowered into working position. In this airlock they
are retained by two conventional arms. Specify that these arms arranged
on each side of the steps do not interfere in any way.

Selon une deurième variante le moyen amployé pour esc@moter les marches est un coulissement herizontal de celles-ci dans des glissières
fixées aur jambes de l'escabeau.
According to a second variant, the amplified means for esc @ moting the steps is a horizontal sliding of these steps in slides.
attached to the legs of the stepladder.

Le dispositif selon l'invention pernet d'escamoter les marches
d'un escabeau afin de @e pas être gêné par les marches supérieures à
à celle utilisée.
The device according to the invention makes it possible to retract the steps
of a stepladder so as not to be bothered by the steps higher than
to the one used.

Le dessin annexé est un discriptif de la premère variante
montrant l'éscab@au avec deux marches baissées, une , demi relevée et
une complètement, ainsi que son utilisation comparativement avec un
escabeau classique.
The attached drawing is a description of the first variant
showing the staircase @ au with two steps down, one half raised and
one completely, as well as its use compared with a
classic stepladder.

Tel qu'il est représenté FIG.1, le dispositif comporte un
escabeau 1 dont les marches 2 pivotent autour de barreaux 3 et sont 0maintenues en position borisontale de travail par des bres 4.La FIG.2.
As shown in FIG.1, the device includes a
stepladder 1 whose steps 2 pivot around bars 3 and are 0 maintained in the borisontal working position by bres 4.La FIG.2.

montre la position de la jambe, à l'aise, lormque il n'y a pas de marche supérieure gênante. La FIG.3.mentre la position de la jambe gênée par une marche supérieure non escamotés.shows the position of the leg, comfortable, when there is no annoying upper step. FIG. 3. ment the position of the leg hampered by an upper step not retracted.

Le dispositif objet de l'invention pout être utilisé lorsque l'on voudra se placer à une h@utour désirée directement en face de la surface à travailler, en toute séourité et confortablement.  The device which is the subject of the invention can be used when one wishes to place oneself at a desired h @ utour directly in front of the surface to be worked, safely and comfortably.
