Abstract

The invention relates to a platform which makes it possible to work on ladders with comfort and without risk of falling. The device comprises four uprights 1, a work board 2, two stay-rods 14, a handrail 4, a plinth 8, an intermediate rail 9, two crosspieces 5, and hooks 6 bearing on the rungs of the ladder 7 at the desired height. A hinge 10 makes it possible to lift the board into position 11 in order to permit access to the platform from below. A spring automatically lifts the board vertically. The device can be folded down after use, by virtue of its trapezoidal shape, after disassembly of the two stay-rods 14. The device according to the invention is intended for all users of ladders.

Description

Le travail sur échelle a toujours présenté des risques de chutes,l'ouvrier a une position instable sur un échelon et il n'a qu'une main de libre pour travailler. Working on a ladder has always presented the risk of falling, the worker has an unstable position on a rung and he has only one free hand to work.

Le Décret NO 65.48 du 8 Janvier I965 (Code du Travail ) n'autorise d'ailleurs un travail n'excédant pas une journée sur une échelle A plus de 3 mètres de'haut quten utilisant une cein -ture ou un baudrier de sécurité. Decree NO 65.48 of January 8, I965 (Labor Code) does not authorize work not exceeding one day on a ladder more than 3 meters high using a belt or a safety harness.

Pour remédier A ces risques,diverses-solutions ont été proposées et un minimum de I5 brevets ont té déposés dans le monde depuis I920. To remedy these risks, various solutions have been proposed and a minimum of 15 patents have been filed worldwide since I920.

Ces solutions sont notamment les suivantes - Marche ou plateforme se fixant sur un échelon de l'échelle. These solutions include the following - Steps or platforms that attach to a rung of the ladder.

- Crinoline ,ceinture ou garde corps.- Crinoline, belt or bodyguard.

- Nacelle monte sur échelle ou sur camion.- Nacelle mounts on ladder or on truck.

les deux premiers types de solutions ne donnent pas une sécurité parfaite. the first two types of solutions do not give perfect security.

La solution nacelle est un dispositif souvent commandé par vérins hydrauliques donc beaucoup plus onéreux que le dispositif proposé. The nacelle solution is a device often controlled by hydraulic cylinders, therefore much more expensive than the proposed device.

L'objet de la présente invention ddfinit une plate-forme légère conforme au décret n 65-48 du code du travail et offrant donc toutes sécurités pour travailler au niveau désiré sur une échelle simple,double,ou è coulisse. The object of the present invention defines a light platform conforming to decree No. 65-48 of the labor code and therefore offering all the safety to work at the desired level on a single, double, or sliding ladder.

les dessins annéxés donnent à titre d'exemple non limitatif deux formes de réalisation de l'objet de l'invention,la solution définitive pouvant utiliser des principes de ces deux formes. the appended drawings give, by way of nonlimiting example, two embodiments of the subject of the invention, the final solution being able to use the principles of these two forms.

Les figures I et 2 montrent pour la première forme de réali
-sation: - les montants verticaux (I) au nombre de quatre.Figures I and 2 show for the first form of reality
- station: - the vertical uprights (I) four in number.

- le plancher de travail (2) maintenu par deux cales (3).- the work floor (2) held by two wedges (3).

- le garde corps (4).- the bodyguard (4).

L'ensemble est maintenu A l'aide des traverses et crochets (5) et (6) prenant appui sur les barreaux de l'échelle (7). The assembly is held in place by means of crosspieces and hooks (5) and (6) bearing on the bars of the ladder (7).

Pour être conforme au décret N 65-48,l'invention comporte également: - une plinthe (8) à 0,I5 m de hauteur. To comply with decree N 65-48, the invention also includes: - a plinth (8) at 0.15 m in height.

- une lisse intermédiaire (9) à 0,45 m de hauteur.- an intermediate beam (9) 0.45 m high.

D'autre part le garde corps est disposé à I,00 m de hauteur. On the other hand, the bodyguard is placed at 1.00 m in height.

te plancher articulé sur la charnière (IO) est relevable en position (II) pour permettre l'accès de l'ouvrier par le bas du dispositif. te hinged floor on the hinge (IO) can be raised to position (II) to allow the worker access from the bottom of the device.

les crochets (5) et (6) permettent de fixer la plate-forme à la hauteur désirée. the hooks (5) and (6) allow the platform to be fixed at the desired height.

Après utilisation,la plate-forme est repliable sur elle même pour faciliter son transport et son rangement. les arceaux consti -tuant la plinthe,la lisse intermddiaire et le garde corps sont démontables par les boulons à oreilles (I2) et rabattables,puis les montants se retlient l'un sur l'autre par l'articulation (I3). After use, the platform is foldable on itself to facilitate its transport and storage. the arches constituting the plinth, the intermediate rail and the bodyguard are removable by the wing bolts (I2) and foldable, then the uprights are retracted one on the other by the joint (I3).

La figure 3 montre pour une deuxième forme de réalisation: - les quatre montants verticaux (I). Figure 3 shows for a second embodiment: - the four vertical uprights (I).

- le plancher de travail (2).- the work floor (2).

- le garde corps (4) disposé à I,00 m de hauteur.- the bodyguard (4) arranged at I, 00 m in height.

- les traverses (5) et les crochets (6) prenant appui sur les barreaux de l'échelle (7) et permettant de fixer la plate-forme la hauteur désirée. - the crosspieces (5) and the hooks (6) bearing on the bars of the ladder (7) and making it possible to fix the platform at the desired height.

- la plinthe (8) à 0,I5 m de hauteur.- the plinth (8) at 0.15 m high.

- la lisse intermédistre (9) à 0,45 m de hauteur.- the intermedister beam (9) at 0.45 m in height.

~ les deux tirants (I4).~ the two tie rods (I4).

Le plancher articulé sur la charnière (IO) est relevable en position (II) en s'écartant de l'échelle pour permettre de ddgager au maximum l'accès de l'ouvrier par le bas. En position horizontale, l'extrémité du plancher prend appui sur la traverse inférieure ou directement sur un barreau de l'échelle. The hinged floor on the hinge (IO) can be raised to position (II) by moving away from the ladder to allow maximum access for the worker from below. In a horizontal position, the end of the floor rests on the lower cross member or directly on a bar of the ladder.

Cette deuxième forme de réalisation est également repliable après utilisation gràce à sa forme trapézoïdale, après démontage des boulons à oreilles (I2) maintenant les tirants (I4). Sa conception d'ensemble doit donner un dispositif plus léger.  This second embodiment is also foldable after use thanks to its trapezoidal shape, after disassembly of the wing bolts (I2) holding the tie rods (I4). Its overall design should give a lighter device.

La figure 4 montre un détail de la traverse supérieure (5),
du crochet (6) avec un boulon de sécurité (I5).FIG. 4 shows a detail of the upper crosspiece (5),
hook (6) with a safety bolt (I5).

Dans les deux formes de réalisation un ressort relève auto- -matiquement le plancher pour permettre l'accès. Pendant le travail, le plancher est maintenu horizontal bar le poids de l'ouvrier. In both embodiments, a spring automatically raises the floor to allow access. During work, the floor is kept horizontal at the weight of the worker.

Selon une variante les boulons à oreilles peuvent être
remplacés par un dispositif de verrouillage avec cran de blocage
pour permettre un pliage plus rapide.According to a variant, the wing bolts can be
replaced by a locking device with locking notch
to allow faster folding.

Selon une variante la plate-forme peut comporter des galets
ou des surfaces de glissement permettant de la déplacer le long de
l'échelle à l'aide d'une corde passant sur une poulie disposée en
haut de l'échelle.According to a variant, the platform may include rollers
or sliding surfaces allowing it to be moved along
the ladder using a rope passing over a pulley arranged in
up the ladder.

La stabilité du bas de ltéchelle est assurée si nécessaire par un stabilisateur traditionnel. The stability of the bottom of the ladder is ensured if necessary by a traditional stabilizer.

La plate-forme peut être réalisée en alliage d'aluminium. The platform can be made of aluminum alloy.

a conception se rapproche beaucoup de celle d'un escabeau pliant de quelques marches Son poids ne devrait pas dépasser 3 h 6 Kgs. he design is very close to that of a folding stepladder of a few steps Its weight should not exceed 3 h 6 Kgs.

La plate-forme est destinée à tous les utilisateurs d'échelle.  The platform is intended for all scale users.
