Abstract

The safety device has an open bracket (1) which the upright of the ladder slides into and a wing nut (2) which allows the bracket to be adjusted to the slope of the ladder. There is a bolt (5) which blocks the ladder upright between the end of the wing nut and the walls of the bracket. There is a cylindrical tube (6) which the wing nut passes through. This tube links the ladder bracket (1) to a second bracket (3) which is attached to a guard rail. The second bracket is open at one end. One side of the bracket is shaped to hold the head of a screw (4), whatever position it is in, and the other side has two sections with bent ends which only hold the screw in place when it is tightened. There is also a wing nut (7) which is tightened manually around the screw against the guard rail, locking the guard rail inside the bracket. A suitably sized screw brake (8) blocks the head of the screw (4) when the device is closed.

Description

DESCRIPTIONDESCRIPTION

La présente invention concerne un dispositif de sécurité assurant la stabilité  The present invention relates to a safety device ensuring stability

des échelles par fixation aux gardecorps.  ladders by fixing to railings.

Traditionnellement, les utilisateurs d'échelles sont exposés aux risques de chutes du fait de l'instabilité de l'échelle. Ces risques concernent dume part le glissement de l'échelle au niveau de ses deux appuis et d'autre part le mouvement de bascule selon une rotation dont le centre serait le point d'appui au sol de l'échelle. Le dispositff selon l'invention permet de remédier à ces inconvénients. Il comporte selon la prmière caractéristique un acceptant d'échelle (1) ouvert sur quatre de ses faces permettant le glissement du montant de l'échelle, le glissement des échelons et le passage d'unme vis papillon (2) cette dernière affectant un mouvement rotatif à l'acceptant d'échelle (1), nécessaire pour l'adaptation à  Traditionally, users of ladders are exposed to the risk of falls due to the instability of the ladder. These risks concern dume on the one hand the sliding of the scale at the level of its two supports and on the other hand the rocking movement according to a rotation whose center would be the fulcrum on the ground of the scale. The dispositff according to the invention overcomes these drawbacks. According to the first characteristic, it includes a scale acceptor (1) open on four of its faces allowing the sliding of the amount of the scale, the sliding of the steps and the passage of a butterfly screw (2) the latter affecting a movement rotatable to the scale acceptor (1), necessary for adaptation to

l'mclmaison de l'échelle.the scale house.

Selon la deuxième c risque le dispositifcomporte aussi une vis papillon (2) fixée à l'acceptant d'échelle (1) par un écrou (5) servant à bloquer le montant de l'échelle entre le bout de la vis papillon (2) et les parois de l'acceptant  According to the second risk c the device also includes a butterfly screw (2) fixed to the ladder acceptor (1) by a nut (5) used to block the amount of the ladder between the end of the butterfly screw (2) and the walls of the acceptor

d'échelle (1).scale (1).

La troisième caractrisque du dispositif est qu'il comporte également un tube cylindrique (6) dans lequel passe la vis papillon (2); ce tube cylindrique (6) relie l'acceptant d'échelle (1) à une attache-grdecp (3) ouverte en ses extrémités pour le logement d'une vis (4) cette dernière pouvant être déplacée entre deux positions correspondant aux états ouvert et fermé du dispositif selon l'invention; l'espace défmini par l'attach-gardecorps (3) et délimité par la vis (4) sert à insérer le grdecorps.  The third characteristic of the device is that it also comprises a cylindrical tube (6) through which the butterfly screw (2) passes; this cylindrical tube (6) connects the scale acceptor (1) to a grdecp attachment (3) open at its ends for the housing of a screw (4) the latter being able to be moved between two positions corresponding to the open states and closed of the device according to the invention; the space defined by the bodyguard attachment (3) and delimited by the screw (4) is used to insert the grdecorps.

Selon la quarie caractéristique le dispositif comporte l'attache-  Depending on the characteristic quarie, the device includes the attachment

gardecorps (3) composée de deux ouvertures différentes aux extrémités de ses deux faces opposées: l'une englobe la tête de la vis (4) quelquesoit la position de cette dernière et l'autre ne retient la vis (4) qu'en position fermée au moyen de deux  railing (3) composed of two different openings at the ends of its two opposite faces: one includes the head of the screw (4) whatever the position of the latter and the other retains the screw (4) only in position closed with two

décrochés en angle (9).angled hooks (9).

Le dispositffpossède selon la cinquième caractérisique un écrou papillon (7) qui se serre manuellement autour de la vis (4) contre l'attachegardecorps (3) et  The device has according to the fifth characteristic a wing nut (7) which is tightened manually around the screw (4) against the bodyguard fastener (3) and

bloque le gardecorps à l'intérieur de l'attache-gardcorps (3).  blocks the railing inside the railing clip (3).

Le dispositf comporte également selon la s''ixième caracistique un frein (8), adapté à la taille de la tête de la vis (4), de façon à pouvoir bloquer la vis (4)  The device also comprises, according to the sixth characteristic, a brake (8), adapted to the size of the head of the screw (4), so as to be able to block the screw (4)

lorsque le dispositif selon l'invention est en position fermée.  when the device according to the invention is in the closed position.

Lorsque le dispositif selon l'invention est serré et bloqué les axes des vis  When the device according to the invention is tightened and blocked the axes of the screws

(2) et (4) sont alors parallèles.(2) and (4) are then parallel.

Le dispositif selon l'invention est conçu pour s'adapter à tous types d'échelles et de gardecorps. Toutefois, il est possible d'adapter l'ensemble du dispositif selon l'invention à des dimensions particulières et ce sans limitation Le dispositif selon l'invention est particulièrement destiné aux travailleurs  The device according to the invention is designed to adapt to all types of ladders and railings. However, it is possible to adapt the entire device according to the invention to particular dimensions and this without limitation The device according to the invention is particularly intended for workers

du bâtiment et des travaux publics.  of building and public works.
