Abstract

Ladder adaptable to any surface. The invention relates to a device which gives stability on any surface, irrespective of its gradient, without the risk of toppling over. It consists of a ladder (1) and (2), of two telescopic arms (5), the base of which has a predetermined angle, with a non-slip end fitting (4), a screwing pin (6), and two spirit levels (7) and (8), one for the horizontal level and the other for the slope of the ladder. The device according to the invention is particularly designed to improve the stability of the ladder, for use in the construction (building) industry.

Description

La présente invention concerne une échelle adaptable sur toute surface, pour éffectuer des travaux dans des cages d'écaliers. The present invention relates to a ladder adaptable to any surface, for carrying out work in stairwells.

les échelles traditionnelles ne disposent pas de bras télescopique incorporé à l'échelle, et de niveau-à bulle, pour la stabilite horizontale, et d'inclinaison de l'échelle, on utilisé des cales, ou, des planches en bois pour compenser le niveau souhaiter, et qu'il ne seront pas stable, et qu'ils risque de se déséquilibrer à tous moment, pendant la durér des travaux, et d'être dangereux pour l'utilisateur et les personnes de passage, par (exemple) on renouvelle une peinture ou papier à l'intérieur d'une cage d'éscalier, d'un bâtiment publique. traditional ladders do not have a telescopic arm incorporated into the ladder, and a spirit level, for horizontal stability, and inclination of the ladder, wedges are used, or wooden planks to compensate for the desired level, and that it will not be stable, and that they risk becoming unbalanced at any time, during the duration of the work, and being dangerous for the user and people passing through, for example renews a painting or paper inside a staircase, in a public building.

Les dispositif selon l'invention permet de remedier à cet inconvienient, il comporte en effet un bras télescopique, à chaque montant de l'échelle, et un axe vissant (boulon), qui permet le blocage du bras télescopique, les deux niveaux à bulle qui permet de vérifier le niveau horizontale et l'inclinaison de l'échelle, qui est prédéterminer par l'embout antidérapant
Quand l'utilisateur travaille par (exemple) dans une cage d'éscalier, un montant de l'échelle va sur une marche d'éscalier, et l'autre montant de l'échelle va sur l'autre marche d'escalier, on déploit le bras télescopique j'usqutà obtenir un niveau horizontale stable, en prenant comme reference le niveau à bulle horizontale, incorporé sur une marche de l'échelle, on introduit l'axe vissant (boulon), et on verifie à l'aide du deuxieme niveau à bulle incorporer près du premier, que l'inclinaison de l'échelle est au niveau, pour éffectuer les travaux dans la cage d'escalier en toute sécurite.The devices according to the invention makes it possible to remedy this drawback, it in fact comprises a telescopic arm, at each upright of the ladder, and a screw pin (bolt), which allows the telescopic arm to be locked, the two spirit levels which allows to check the horizontal level and the inclination of the ladder, which is predetermined by the non-slip tip
When the user works (for example) in a stairwell, one amount of the ladder goes on one stair step, and the other amount of the ladder goes on the other stair step, we deploy the telescopic arm I used to obtain a stable horizontal level, taking as a reference the horizontal bubble level, incorporated on a step of the ladder, we introduce the screw axis (bolt), and we verify using the second spirit level incorporate near the first, that the inclination of the ladder is level, to carry out the work in the stairwell safely.

Selon une forme de realisation pérferentielle les deux bras télescopique constitue une partie de l'échelle, l'autre partie étant un niveau horizontale et un niveau d'inclinaison, et un axe vissant (boulon). According to a perferential embodiment, the two telescopic arms constitute a part of the scale, the other part being a horizontal level and a level of inclination, and a screw axis (bolt).

le dispositif peut-etre realise en matiere aluminium ou, autre matiere. the device can be made of aluminum material or another material.

La figure 1 represente le dispositif selon l'invention. Figure 1 shows the device according to the invention.

La figure 2 represente en coupe les deux niveaux horizontale et d'inclinaison. Figure 2 shows in section the two horizontal and tilt levels.

La figure 3 represente le bras télescopique et l'axe vissant (boulon).  Figure 3 shows the telescopic arm and the screw axis (bolt).

le dispositif represente sur la figure 1,2,3 comporte une échelle (1) et (2) de dimension de l'ordre de deux metre pour la hauteur, et 0,34 metre pour la largeur, et 3,5 cm pour l'épaisseur, dans l'une des marche (2) deux niveaux (7) et (8) sont incorporer pour la position horizontale et d'inclinaison de l'échelle, les deux bras télescopique (5) sont incorporer à échelle (1) et (2), reglable de 0 cm à 25 cm pour obtenir le niveau sauhaiter de l'échelle, et des embouts antidérapants(4) et (3), avec un angle d'inclinaison prédéterminer, quand le niveau (7) de l'échelle est bien positionné, et le niveau d'inclinaison (8), on introduit l'axe vissant (boulon) (6) dans l'un des trous (9), et on bloque l'axe vissant (6). the device represented in figure 1,2,3 includes a scale (1) and (2) of dimension of the order of two meters for the height, and 0.34 meters for the width, and 3.5 cm for the thickness, in one of the steps (2) two levels (7) and (8) are incorporated for the horizontal position and inclination of the ladder, the two telescopic arms (5) are incorporated on the ladder (1) and (2), adjustable from 0 cm to 25 cm to obtain the desired level of the scale, and non-slip tips (4) and (3), with a predetermined angle of inclination, when the level (7) of l 'scale is well positioned, and the level of inclination (8), we introduce the screw axis (bolt) (6) in one of the holes (9), and we block the screw axis (6).

le dispositif selon l'invention est particulierement destine à l'amelioration de la stabilite de l'échelle, et pour l'industrie du bâtiment, et menagée.  the device according to the invention is particularly intended for the improvement of the stability of the ladder, and for the building industry, and managed.
