Abstract

This invention is a device in the form of a console having a top 103 supported by two crosspieces 102 having a straight edge 106A, the edge opposite 106 being in the form of a V. This V consists of a flat metal part 106 of approximately 10 x 60 on which is bonded a rubber 106c which will reinforce the nonskid action. This form is intended to be applied against a cylindrical object or against a wall angle, thereby preventing any risk of skidding. Its top plate 103 thus offers the possibility of placing tools and serves as a shelf. By virtue of a system of braces 111 and 112 it will be possible for this shelf to be adjusted according to the inclination given to the ladder element relative to its support (post or wall angle).

Description

La présente invention concerne un dispositif à console PL. 1/5 fig 39 se fixant à l'extrémité de un ou plusieurs éléments d'échelle, fig 8 et 10, formant ainsi une tablette pour travailler.The present invention relates to a PL console device. 1/5 fig 39 attaching to the end of one or more ladder elements, fig 8 and 10, thus forming a shelf for working.

Cette console est conçue principalement dans le but de pouvoir travailler en toute sécuri té, en s'appuyant comme le montre PL. 3/5 fig 43: soit contre un objet cylindrique (A)( pilier), ou un angle de mur (B)
Sa tablette (103) servira de table de travail; où l'on pourra poser les outils. Une jambe de force PL. 4/5 fig 44 en 111 et 112 permet le réglage et le maintient en position horizontal de la tablette.This console is designed mainly for the purpose of being able to work in complete safety, using as shown by PL. 3/5 fig 43: either against a cylindrical object (A) (pillar), or a wall angle (B)
Its shelf (103) will serve as a work table; where we can put the tools. A PL strut. 4/5 fig 44 in 111 and 112 allows the adjustment and maintains it in horizontal position of the tablet.

Il est souvent trés difficile de travailler sur une échelle en tenant ses outils dans les mains, même si l'on a de grandes poches, on ne voit pas toujours l'outil qu'il nous faut et quand il faut; puis on ne peut pas tout mettre. Hors sur une tablette on peut poser une caisse à outils.It is often very difficult to work on a ladder while holding your tools in your hands, even if you have large pockets, you do not always see the tool we need and when we need it; then we can't put everything. Outside on a shelf you can put a toolbox.

Néanmoins, il est trés possible si on la fixe à deux éléments d'échelle,
PL.4/5 fig 44, d'en faire une forme d'escabeau, mais un escabeau spécial, qui pourra s'agrandire à la demande.However, it is very possible if it is fixed to two scale elements,
PL.4 / 5 fig 44, to make it a form of stepladder, but a special stepladder, which can be enlarged on demand.

En effet, on sait que la demande de brevet déposée 1e29.04.86 sous le
N 86/06410 et rendue public sous le NO 2 597 920, possède des éléments d'échelle s'emboitant les uns dans les autres, pouvant ainsi constituer une échelle trés grande.Indeed, we know that the patent application filed 1e29.04.86 under the
N 86/06410 and made public under NO 2 597 920, has ladder elements which fit together, thus constituting a very large ladder.

Hé bien il en est de même pour cette forme d'escabeau. (exemple: si l'on veut poser du lambris sous des chevrons, en se posant sur un balcon, la hauteur d'un élément suffira. Par contre, si l'on veut faire le même travail, mais à partir du sol, deux éléments seront nécéssaires.) De plus, une entretoise téléscopique PL. 4/5 fig 44 en 108 et 109 permet le maintient des pieds, soit: en position fixe, mais aussi plus ou mois écartés, d'où une plus grande souplesse dans le positionnement.Cela peut permettre d'enjamber ou d'éviter un monticule
Ce dispositif selon l'invention PL. 2/5 est constitué; d'une tablette (103) supportée par deux traverses tao2) aprés léquelles sont fixés deux pieds(100) équipés de tenons (131) qui permettrons un assemblage avec un élément d'échelle PL.1/5 fig 8, puis deux bras (129) qui en assurerons le parfait maintient.Well it is the same for this form of stepladder. (example: if you want to put paneling under rafters, by landing on a balcony, the height of one element will be enough. However, if you want to do the same work, but from the ground, two elements will be necessary.) In addition, a PL telescopic spacer. 4/5 fig 44 in 108 and 109 allows the feet to be held, either: in a fixed position, but also more or less apart, hence greater flexibility in positioning. This can allow to step over or avoid a mound
This device according to the invention PL. 2/5 is formed; of a shelf (103) supported by two crosspieces tao2) after which are fixed two feet (100) equipped with tenons (131) which will allow an assembly with a ladder element PL.1 / 5 fig 8, then two arms ( 129) which will ensure its perfect maintenance.

Deux pieds plus petits (101) pourront également recevoir un élément d'échelle. PL. 1/5 fig 10 Du coté de l'échelle qui aura les tenons et bras d'assemblage.Two smaller feet (101) can also receive a ladder element. PL. 1/5 fig 10 On the side of the ladder which will have the tenons and assembly arms.

Les tenons (131) ainsi que les bras (129) seront de même type-que ceux décrit dans la demande de brevet principal. The studs (131) and the arms (129) will be of the same type as those described in the main patent application.

PL. 4/5 fig 44, une crémaillère téléscopique, composée de deux carrés creux coulissant l'un dans l'autre, permet un réglage de mise à niveau selon l'inclinaison de l'ensemble. Afin d'assurer une meilleur rigidité de l'ensemble, dans le cas où l'on aboute plusieurs élements d'échelle on placera l'entretoise de la même façon que le montre PL. 3/5 fig 43 en 107 et 108, formant ainsi un triangle ressemblant à une charpente répartissant ainsi au maximum la flexion.PL. 4/5 fig 44, a telescopic rack, composed of two hollow squares sliding one inside the other, allows leveling adjustment according to the inclination of the assembly. To ensure better rigidity of the assembly, in the case where there are several scale elements, the spacer will be placed in the same way as shown in PL. 3/5 fig 43 in 107 and 108, thus forming a triangle resembling a frame thus distributing the bending as much as possible.

PL.3/5 fig 43, en ( A et B) nous avons une idée de l'utilisation de cette tablette. En (A), posée contre un support cylindrique, en (B) posée contre un angle de mur.PL.3 / 5 fig 43, in (A and B) we have an idea of the use of this tablet. In (A), placed against a cylindrical support, in (B) placed against a wall angle.

Pu.1/5. fig 44 en 107 et 108, on remarque l'entretoise télescopique, qui assure le maintient des pieds lors de l'utilisation en escabeau géant fig 45, le détail de verrouilage de cette entretoise montre un système simple. La partie (109) est un étrier, qui, d'un côté s'emboite dans les carré creux (108 ou 109), et de lautre permet l'accrochage sur les échelons. Le verrouillage est assuré par une tige métallique en forme de "S", qui vient se loger dans la partie inférieur de l'étrier. Pu. 1/5. fig 44 in 107 and 108, we notice the telescopic spacer, which provides support for the feet when using a giant stepladder fig 45, the locking detail of this spacer shows a simple system. The part (109) is a stirrup, which, on one side fits into the hollow square (108 or 109), and on the other allows hooking on the rungs. Locking is ensured by a metal rod in the shape of an "S", which is housed in the lower part of the bracket.

afin de lui assurer une mise en position parfaite, et ainsi éviter un risque d'ouverture lors du transport sur le chantier, on lui mettra en (113) un ressort de rappel.in order to ensure a perfect positioning, and thus avoid a risk of opening during transport to the site, it will be put in (113) a return spring.

PL. 5/5 fig 46, on voit ici le dispositif dans la position pliée.PL. 5/5 fig 46, we see here the device in the folded position.

On remarque, que l'ensemble des composants forment une surface plane, réduisant ainsi l'encombrement, facilitant son transport et son rangement. Note that all of the components form a flat surface, thus reducing the size, facilitating its transport and storage.
