Abstract

The ladder has two adjustable ends that slip into a set of covers, and a set of bolts (3, 4) that is utilized for fixing ends of the ladder into the ground. A set of bearing surfaces of the ladder is arranged to have different heights. A set of additional support points (A, B) is arranged so as to allow the ladder to take support on the ground, where the set of additional support points are provided in an adjustable manner.

Description

Description Cette innovation est une échelle avec des points d'appui qui sont réglables, et avec 2 points d'appui supplémentaires pour éviter le glissement sur la terre. Les défauts des échelles existantes sont : -d'abord elles glissent lorsque l'on augmente la force horizontale plus que la résistance de friction à la terre (à cause d'un excès de poids ou d'un faible angle d'appui) causant des accidents, -le second est la non stabilité de deux points d'appui non Io réglables qui ne sont pas compatibles avec les surfaces d'appui d'hauteurs inégales, horizontalement ou verticalement, et surtout dans les cages d'escaliers. Cette innovation permet d'éviter ces défauts. Les 2 points d'appui sont réglables : on peut 1 5 augmenter ou diminuer l'un d'eux ou les deux, sur le sol ou sur le mur, en faisant glisser le bout de l'échelle dans la housse et le fixer avec 2 boulons Fig.1. Ce dispositif assure la stabilité, même si les 2 points d'appui se trouvent sur des marches d'escalier. 2o deux L'ajout de de points d'appui, comme la Fig.1 le montre, fait que les 2 points d'appui de l'échelle deviennent antidérapants dans le sens de la flèche Fig. 1. Ces points d'appui supplémentaires sont aussi réglables et les deux boulons 3 et 4 fixent le bout de l'échelle qui 15 glisse dans la housse. Ces 2 points d'appui peuvent se trouver sur deux surfaces d'appui qui n'ont pas les mêmes hauteurs. Ce dispositif assure le contact des points d'appui des quatre bouts de l'échelle sur des surfaces inégales, afm d'assurer la stabilité et d'assurer l'anti-dérapage horizontal des 2p points d'appui sur la surface de la terre. Fig. (1) il y 12 boulons (3 et 4) qui assure la fixation de la partie glissante A et B sont les 2 points d'appui supplémentaires qui assure l'anti-dérapageDescription This innovation is a ladder with support points that are adjustable, and with 2 additional points of support to prevent slipping on the ground. The defects of the existing ladders are: -First they slide when the horizontal force is increased more than the friction resistance to the ground (because of an excess of weight or a low angle of support) causing accidents, -the second is the non-stability of two non-adjustable bearing points that are not compatible with the bearing surfaces of unequal heights, horizontally or vertically, and especially in the stairwells. This innovation avoids these defects. The 2 support points are adjustable: you can increase or decrease one of them or both, on the floor or on the wall, by sliding the end of the ladder into the cover and fix it with 2 bolts Fig.1. This device ensures stability, even if the 2 points of support are on stair steps. 2o two The addition of points of support, as shown in Fig.1, makes the 2 points of support of the ladder become non-slip in the direction of the arrow Fig. 1. These additional support points are also adjustable and the two bolts 3 and 4 fix the end of the ladder which slides into the cover. These 2 points of support can be on two bearing surfaces that do not have the same heights. This device ensures the contact of the points of support of the four ends of the ladder on uneven surfaces, in order to ensure the stability and to ensure the horizontal anti-skid of the 2p points of support on the surface of the earth. . Fig. (1) there are 12 bolts (3 and 4) which ensures the fixing of the sliding part A and B are the 2 additional points of support which ensures the anti-skid
