To this end, the plate 12 of the fastener 11 is monolithic with the bearing 10 of the single cleat 5 that it carries and comprises, below this bearing 10, a tubular liner 14 having the same sectional shape as the bar B1 which it surrounds and with which it cooperates to ensure its own positioning, said platen being fixed by a single means 18 against the upright M of the fixed plane 2 and so that the bearing 10 faces projecting towards the inside of the scale and that the notches 5a of the cleat are opposite the splines 20 of the bar B1.

Description

Pour travailler en hauteur, par exemple sur les lignes électriques basse tension ou sur les lignes téléphoniques portées par des poteaux, il est connu d'utiliser des échelles s'appuyant sur le poteau 1, comme montré figure 1, ou, disposées près du poteau, mais s'appuyant sur des jambes de soutien. L'échelle comprend un plan fixe 2 formé par assemblage de montants M avec des barreaux B. Pour sécuriser l'échelle quand elle est en appui contre le poteau 1, et pour former un ensemble rigide, insensible aux variations de charges et au couple de basculement engendré par le déplacement de la personne sur l'échelle, à son sommet ou sur sa plateforme sommitale, elle est haubanée sur le poteau. A cette fin elle comporte une corde d'haubanage 4 qui entoure le poteau et dont les brins sont tendus entre les montants du plan fixe 2 et le poteau 1. Dans d'autres applications, par exemple avec une échelle équipée de jambes de soutien, la corde de haubanage est tendue entre l'échelle et un point d'accrochage fixe.To work at height, for example on low-voltage power lines or telephone lines carried by poles, it is known to use ladders based on the pole 1, as shown figure 1 , or, arranged near the pole, but leaning on supporting legs. The ladder comprises a fixed plane 2 formed by assembling M uprights with bars B. To secure the ladder when it is in abutment against the post 1, and to form a rigid assembly, insensitive to load variations and the torque of tipping caused by the movement of the person on the ladder, at its summit or on its summit platform, it is guyed on the pole. For this purpose it comprises a guying rope 4 which surrounds the post and whose strands are stretched between the uprights of the fixed plane 2 and the post 1. In other applications, for example with a ladder equipped with support legs, the guying rope is stretched between the ladder and a fixed attachment point.

La corde de haubanage de l'échelle est calée sur les montants par des taquets coinceurs 5 qui sont rapportés et fixés par des vis contre les faces internes des deux montants du plan fixe 2.The guy rope of the ladder is wedged on the uprights by jamming cleats 5 which are attached and fixed by screws against the inner faces of the two uprights of the fixed plane 2.

Habituellement, chaque taquet est composé d'une platine portant deux axes transversaux sur chacun desquels sont montés rotatifs deux taquets de forme ovoïdale rappelés élastiquement l'un contre l'autre. Ces taquets sont disposés de part et d'autre du plan de serrage de la corde d'haubanage. La face courbe de chaque taquet, qui est tournée vers l'autre taquet, est munie d'arrêtes transversales crantées aptes à s'opposer aux déplacements de la corde de haubanage 4. Le platine porte taquet est fixée par des vis sur la paroi interne de chacun des montants M du plan fixe 2.Usually, each cleat is composed of a plate carrying two transverse axes on each of which are rotatably mounted two cleats of ovoidal shape resiliently biased against each other. These cleats are arranged on either side of the clamping plane of the guying rope. The curved face of each cleat, which is turned towards the other cleat, is provided with notched transverse ridges adapted to oppose the movements of the guying rope 4. The cleat bearing platen is fixed by screws on the inner wall of each of the M amounts of the fixed plan 2.

Bien que donnant satisfaction, de tels taquets présentent les inconvénients suivants :

  • le premier est qu'ils nécessitent de percer deux trous dans chaque montant, avec pour conséquence d'affaiblir localement ce montant.
  • Le second résulte de leur structure et de leur positionnement qui, sous des efforts de traction exagérés de la corde sur eux, amplifient le couple de basculement sur les taquets qui tend vers leur arrachement de la platine.
Although satisfactory, such cleats have the following drawbacks:
  • the first is that they require drilling two holes in each amount, with the result of weakening locally this amount.
  • The second results from their structure and their positioning which, under exaggerated tensile forces of the rope on them, amplify the tilting torque on the cleats which tends towards their tearing of the plate.

Bien que le risque d'arrachement soit très faible, son existence suffit à générer un sentiment d'insécurité sur l'utilisateur de l'échelle.Although the risk of tearing is very low, its existence is enough to generate a feeling of insecurity on the user of the scale.

L'objet de l'invention est de remédier à ces inconvénients en fournissant des moyens de coincement de la corde de haubanage réduisant le nombre de trous pour le fixer sur le montant de l'échelle et augmentant sa résistance à l'arrachement.The object of the invention is to overcome these disadvantages by providing means for jamming the guying rope reducing the number of holes to fix it on the amount of the ladder and increasing its resistance to tearing.

Elle concerne plus spécialement les échelles dans lesquelles, comme décrit dans le document FR1360240 au nom de la déposante, chacun des barreaux présente des cannelures longitudinales saillant de sa face supérieure pour l'appui du pied de l'utilisateur, et est tubulaire, par exemple avec une section de forme triangulaire avec son coté cannelé vers le haut.It concerns more especially the scales in which, as described in the document FR1360240 in the name of the applicant, each of the bars has longitudinal grooves protruding from its upper face for the support of the foot of the user, and is tubular, for example with a triangular section with its fluted side upwards.

Selon l'invention, la platine de la pièce de fixation est monolithique avec le palier de l'unique taquet qu'elle porte et comporte, au dessous de ce palier, une chemise tubulaire ayant la même forme que le barreau B1 qu'elle entoure et avec lequel elle coopère pour assurer son positionnement, la dite platine étant fixée par un seul moyen de fixation contre le montant M du plan fixe et de manière que le palier face saillie vers l'intérieur de l'échelle et que les crans du taquet soient en vis-à-vis des cannelures de l'un des barreaux, pour former avec eux des mâchoires de serrage de la corde de haubanage..According to the invention, the plate of the fastener is monolithic with the bearing of the single cleat it carries and comprises, below this bearing, a tubular jacket having the same shape as the bar B1 that surrounds it and with which it cooperates to ensure its positioning, said platen being fixed by a single fastening means against the upright M of the fixed plane and so that the bearing face protruding inwardly of the scale and the notches of the cleat are vis-à-vis the grooves of one of the bars, to form with them clamping jaws of the guy rope.

La pièce monolithique est mise en place entoure du barreau lors du montage de celui-ci sur les montants, tandis que la fixation définitive de sa platine sur le montant est assurée par l'unique moyen de liaison, tel que vis, rivet.The monolithic piece is placed around the bar when mounting it on the uprights, while the final fixing of its plate on the upright is provided by the single connecting means, such as screw, rivet.

Dans une forme d'exécution, la pièce monolithique comporte, au dessous du palier pour le taquet, une chemise tubulaire ayant la même forme que le barreau qu'elle entoure sans jeu.In one embodiment, the monolithic piece comprises, below the bearing for the stopper, a tubular jacket having the same shape as the bar which it surrounds without play.

Cette chemise positionne la pièce et le taquet coinceur et, surtout, améliore la résistance au couple d'arrachement.This shirt positions the workpiece and the cleat and, above all, improves the resistance to tearing torque.

D'autres caractéristiques et avantages ressortiront de la description qui suit, en référence au dessin schématique annexé, représentant une forme d'exécution de l'invention.

  • Figures 5, 6 et 7 sont de vues de coté en élévation d'un taquet quand il est, respectivement, en position d'attente, en position de coincement d'une corde et en position de libération manuelle d'une corde.
Other features and advantages will become apparent from the description which follows, with reference to the attached schematic drawing, showing an embodiment of the invention.
  • Figure 1 is a perspective view of a state-of-the-art scale;
  • Figure 2 is a partial perspective view showing, on an enlarged scale, an embodiment of the cleat according to the invention, when it is in the jamming position;
  • Figure 3 is a perspective view of the monolithic piece alone;
  • Figure 4 is a perspective view of the cleat when in the waiting position of a rope;
  • Figures 5, 6 and 7 are side views in elevation of a cleat when it is, respectively, in the waiting position, in the wedging position of a rope and in the position of manual release of a rope.

Dans la forme d'exécution représentée aux figures 2 à 7, à chaque montant du plan fixe 2 de l'échelle est associé un seul taquet 5 qui est monté libre en rotation sur un palier 10 faisant partie d'une pièce de fixation 11, monolithique et moulée en métal.In the form of execution shown in Figures 2 to 7 , at each amount of the fixed plane 2 of the scale is associated a single latch 5 which is rotatably mounted on a bearing 10 forming part of a fastener 11, monolithic and molded metal.

Comme on peut le voir à la figure 3, le palier 10 fait saillie en direction de l'intérieur de l'échelle à partir d'une platine 12. Celle-ci comporte, à son extrémité supérieure, un trou circulaire 13 pour le passage d'un moyen de fixation, tel que rivet ou vis, et, à son extrémité inférieure, une chemise tubulaire 14 dont la forme de la section est la même que celle du barreau B1 qu'elle va entourer avec un jeu réduit. Dans cette forme de réalisation elle présente une section triangulaire arrondie. Ainsi, la chemise 14 est positionnée angulairement par le barreau et renforce la pièce monolithique 11.As can be seen at figure 3 , the bearing 10 projects towards the inside of the ladder from a plate 12. The latter comprises, at its upper end, a circular hole 13 for the passage of a fixing means, such as rivet or screw, and at its lower end, a tubular liner 14 whose shape of the section is the same as that of the bar B1 that it will surround with a reduced clearance. In this embodiment it has a rounded triangular section. Thus, the liner 14 is angularly positioned by the bar and strengthens the monolithic piece 11.

La paroi 14a de la chemise, qui est tournée vers le poteau 1, est prolongée vers le haut par une nervure 15 renforçant la pièce en formant un gousset. La figure 3 montre que la nervure 15 est traversée par un trou 16 pour le passage de la corde d'haubanage 4.The wall 14a of the liner, which is turned towards the post 1, is extended upwards by a rib 15 reinforcing the workpiece forming a gusset. The figure 3 shows that the rib 15 is traversed by a hole 16 for the passage of the guying rope 4.

Enfin, le corps du palier 10 est relié à la platine 12 par des nervures radiales 17 lui conférant une très bonne résistance à l'arrachementFinally, the body of the bearing 10 is connected to the plate 12 by radial ribs 17 giving it a very good resistance to tearing off

De façon connue, le taquet 5 comporte un alésage axial, non représenté, par lequel il est monté rotatif sur le palier 10. Il contient des moyens de rappel élastique, tel qu'un ressort en spirale, orientant sa face courbe crantée 5a en direction des cannelures sous jacentes 20 du barreau B1.In known manner, the cleat 5 comprises an axial bore, not shown, by which it is rotatably mounted on the bearing 10. It contains elastic return means, such as a spiral spring, orienting its toothed curved face 5a in the direction underlying grooves 20 of the bar B1.

Les deux pièces de fixation 11 sont mises en place sur les montants M du plan fixe 2, lorsque le barreau commun B1 qui les porte est lui-même fixé par ses extrémités sur les montants M. La fixation des barreaux s'effectue soit par dudgeonnage sur les montants, soit par une vis axiale prenant appui sur le montant, tandis que celle des pièces 11 sur ces mêmes montants s'effectue par un seul rivet 18 passant à travers le trou 13 de chaque platine 12.The two fixing pieces 11 are put in place on the uprights M of the fixed plane 2, when the common bar B1 which carries them is itself fixed by its ends on the uprights M. The fixing of the bars is carried out either by expansion on the uprights, either by an axial screw bearing on the upright, while that of the parts 11 on the same amounts is effected by a single rivet 18 passing through the hole 13 of each plate 12.

Les figures 2 et 6 montrent que, quand le taquet 5 est en position de coincement, sa face crantée 5a coopère avec les cannelures 20 du barreau B1, à la façon de mâchoires de serrage, pour agripper la corde 4 qui passe entre eux.The figures 2 and 6 show that when the latch 5 is in the jamming position, its notched face 5a cooperates with the splines 20 of the bar B1, in the manner of clamping jaws, to grip the rope 4 which passes between them.

Dans cette position, les taquets 5 sont autobloquants vis-à-vis de la corde 4 et absorbent aisément les efforts de traction qui leurs sont communiqués dans le sens de la flèche 21 de figure 2. La rigidité donnée aux pièces 11 par la chemise 14, la nervure de gousset 15 et les nervures 17, permet à ces pièces de résister aux efforts d'arrachement s'exerçant sur les montants tubulaires M qui les portent, d'autant plus que ces montants ne sont pas affaiblis par les fixations des platines 12 de la pièce 11.In this position, the catches 5 are self-locking with respect to the rope 4 and easily absorb the tensile forces communicated to them in the direction of the arrow 21 of FIG. figure 2 . The rigidity given to the parts 11 by the liner 14, the gusset rib 15 and the ribs 17, allows these parts to withstand the pulling forces exerted on the tubular uprights M which carry them, especially as these The amounts are not weakened by the fixings of the plates 12 of the part 11.

Quand il n'y a pas de corde 4, les moyens de rappel élastique maintiennent le taquet dans la position d'attente montrée aux figures 4 et 5, position dans laquelle les crans 5a du taquet ne viennent pas au contact des cannelures 20, et un intervalle S est ménagé entre taquet et barreau.When there is no rope 4, the elastic return means hold the stopper in the waiting position shown to Figures 4 and 5 position in which the notches 5a of the cleat do not come into contact with the grooves 20, and an interval S is formed between cleat and bar.

Pour libérer la corde 4 et permettre de décoller l'échelle de son appui sur le poteau 1 avant son repliement pour le transport, l'opérateur doit exercer sur chacun des deux brins de la corde 4 une traction dans le sens de la flèche 22 à la figure 7. Comme le montre la figure 6 cela a pour effets d'éloigner les taquets 5 de la corde 4 et de permettre de la laisser filer dans le sens inverse de la flèche 22.To release the rope 4 and allow the ladder to take off from its support on the post 1 before its folding for transport, the operator must exert on each of the two strands of the rope 4 a traction in the direction of the arrow 22 to the figure 7 . As shown in figure 6 this has the effect of moving the tabs 5 away from the rope 4 and allowing it to be left in the opposite direction to the arrow 22.

Il ressort de la description qui précède que le taquet selon l'invention facilite sa pose et son positionnement sur les montants, et présente une résistance à l'arrachement bien supérieure à celle des taquets existants, tout en améliorant la sécurité de l'utilisateur.It follows from the foregoing description that the cleat according to the invention facilitates its installation and positioning on the uprights, and has a tear resistance much higher than that of existing cleats, while improving the safety of the user.
