It is designed so that the movable jaws can be set in an intermediate position with a gap large enough to allow the clamp to pass over supports on the safety line holding it to the wall. A control member (11) allows the jaw gap to be widened for fitting and removing the clamp, while is it automatically closed completely if a pull is applied to the handle.

Description

La présente invention se rapporte à un coulisseau pour ligne de vie.The present invention relates to a slide for lifeline.

L'invention vise, plus particulièrement, un coulisseau destiné à être monté sur une ligne de vie fixée horizontalement le long d'une paroi, ledit coulisseau étant destiné à être relié par un câble à un harnais ou à une ceinture, porté par un ouvrier travaillant le long de la paroi afin de le protéger en cas de chute accidentelle.The invention relates, more particularly, to a slide intended to be mounted on a lifeline fixed horizontally along a wall, said slide being intended to be connected by a cable to a harness or to a belt, worn by a worker working along the wall to protect it in case of accidental fall.

L'un des buts de la présente invention est de réaliser un coulisseau qui peut aisément être monté sur la ligne de vie, qui peut aisément glisser sur celle-ci et qui offre une grande sécurité.One of the aims of the present invention is to achieve a slide which can easily be mounted on the line of life, which can easily slide on it and which offers great security.

Le coulisseau, selon l'invention, est destiné à être utilisé avec une ligne de vie horizontale comprenant un câble s'étendant le long d'une paroi et relié à celle-ci par des supports, ledit coulisseau étant du type comprenant un corps présentant une gouttière dans laquelle coulisse le câble, une poignée destinée à recevoir l'une des extrémités d'une longe dont l'autre extrémité est reliée à un harnais de sécurité et une mâchoire mobile de manière à permettre de former une fente dans la gouttière afin de pouvoir monter le coulisseau sur le câble, ledit coulisseau étant caractérisé en ce qu'il comporte des moyens pour maintenir la mâchoire légèrement écartée dans une première position intermédiaire de manière à ménager une fente correspondant à l'épaisseur des supports du câble, des moyens pour commander l'écartement de la mâchoire pour agrandir la fente dans une seconde position d'ouverture afin de pouvoir monter le coulisseau sur le câble et des moyens pour placer automatiquement le coulisseau dans une position de sécurité si une traction est appliquée sur la poignée, la mâchoire mobile étant basculée pour que la fente soit complètement obturée.The slide, according to the invention, is intended to be used with a horizontal lifeline including a cable extending along a wall and connected to it by supports, said slide being of the type comprising a body with a gutter in which the cable, a handle intended to receive one of the ends a lanyard the other end of which is connected to a harness and a movable jaw so as to allow to form a slot in the gutter in order to be able to climb the slide on the cable, said slide being characterized in that it includes means for maintaining the jaw slightly apart in a first intermediate position so as to provide a slot corresponding to the thickness of the cable supports, means for controlling the jaw spacing to enlarge the slot in a second opening position in order to be able to mount the slide on the cable and means for automatically placing the slide in a safe position if a traction is applied to the handle, the movable jaw being tilted so that the slot is completely closed.

Grâce à cette disposition, on peut très aisément monter le coulisseau sur le câble, celui-ci pouvant aisément glisser le long du câble, même au droit des supports, et si l'utilisateur vient à chuter, la fente est refermée.Thanks to this arrangement, it is very easy to mount the slide on the cable, which can easily slide along the cable, even to the right of the supports, and if the user falls, the slot is closed.

Suivant une caractéristique constructive, la mâchoire mobile est articulée sur un axe et comporte un talon mobile à l'intérieur du corps contre l'action de moyens élastiques tendant à amener la mâchoire mobile vers une position de fermeture de la fente, tandis que la poignée est supportée par un axe mobile dans un canal du talon, le corps comportant une came avec laquelle coopère l'axe de la poignée, ladite came et ledit canal étant inclinés en sens opposé par rapport à la verticale de manière que, lorsque l'axe de la poignée est déplacé vers le bas, la mâchoire tend à basculer vers la position de sécurité, tandis que lorsque ledit axe de la poignée est déplacé vers le haut, la mâchoire tend à basculer vers la position d'ouverture.According to a constructive characteristic, the jaw mobile is articulated on an axis and has a heel mobile inside the body against the action of means elastic tending to bring the movable jaw to a position closing the slot, while the handle is supported by a movable axis in a heel channel, the body comprising a cam with which the axis of the handle, said cam and said channel being inclined in direction opposite from the vertical so that when the axis of the handle is moved down, the jaw tends to tip over to the safety position, while when said axis of the handle is moved upwards, the jaw tends to tilt towards the open position.

Suivant une autre caractéristique, le talon comporte une lumière transversale dans laquelle coulisse, contre l'action de moyens élastiques, un poussoir comportant une échancrure susceptible d'être amenée en regard de l'axe de la poignée de manière que ledit axe puisse être déplacé vers le haut pour que la mâchoire puisse être basculée vers la position d'ouverture.According to another characteristic, the heel has a transverse light in which slides, against the action of elastic means, a pusher comprising a notch likely to be brought opposite the axis of the handle so that said axis can be moved upwards so that the jaw can be tilted towards the open position.

Suivant encore une autre caractéristique constructive, l'axe de la poignée est poussé vers le haut par des moyens élastiques de manière à porter contre le poussoir, dans cette position la mâchoire étant maintenue dans la position intermédiaire.According to yet another constructive characteristic, the handle axis is pushed up by elastic means so as to bear against the pusher, in this position the jaw being held in the position intermediate.

De préférence, les moyens élastiques tendant à faire basculer la mâchoire mobile vers la position de fermeture de la fente sont constitués par une épaisseur de matière plastique cellulaire élastique.Preferably, the elastic means tending to make tilt the movable jaw to the closed position of the slit consist of a thickness of material elastic cellular plastic.

Enfin, les moyens élastiques tendant à pousser vers le haut l'axe de la poignée dans le canal sont constitués par une épaisseur de matière plastique cellulaire élastique insérée entre le fond du canal et ledit axe. Finally, the elastic means tending to push towards the top the axis of the handle in the channel are made up by a thickness of elastic cellular plastic inserted between the bottom of the channel and said axis.

L'invention va maintenant être décrite avec plus de détails en se référant à un mode de réalisation particulier donné à titre d'exemple seulement et représenté aux dessins annexés, dans lesquels :The invention will now be described with more details with reference to a particular embodiment given by way of example only and shown in the drawings annexed, in which:

Figure 1 est une vue en perspective d'un coulisseau, selon l'invention, celui-ci étant dans la position intermédiaire.FIG. 1 is a perspective view of a slide, according to the invention, the latter being in the intermediate position.

Figure 2 est une vue en perspective, le coulisseau étant en position ouverte.Figure 2 is a perspective view, the slide being in the open position.

Figure 3 montre en perspective le coulisseau dans la position intermédiaire monté sur une ligne de vie.Figure 3 shows in perspective the slide in the intermediate position mounted on a lifeline.

Figure 4 et figure 5 sont des vues en perspective avec des arrachements et montrant respectivement le coulisseau en position intermédiaire et ouverte.Figure 4 and Figure 5 are perspective views with cutouts and respectively showing the slide in the intermediate and open position.

Figure 6 est une vue en coupe suivant la ligne 6-6 de la figure 1.Figure 6 is a sectional view along line 6-6 of figure 1.

Figure 7 est une vue en coupe suivant la ligne 7-7 de la figure 2.Figure 7 is a sectional view along line 7-7 in Figure 2.

Figure 8 est une vue similaire aux figures 6 et 7, mais le coulisseau occupe une position active dans laquelle l'utilisateur est sensé avoir chuté.Figure 8 is a view similar to Figures 6 and 7, but the slide occupies an active position in which the user is assumed to have dropped.

Le coulisseau représenté aux figures comprend un corps 1 présentant, à sa partie supérieure, une gouttière 2 avec une fente 4 et délimitée par une mâchoire fixe 3 et une mâchoire mobile 5, celle-ci s'articulant sur un axe 6 et étant prolongée par un talon 7 mobile à l'intérieur du corps 1 contre l'action d'un moyen élastique constitué ici par une épaisseur de matière plastique cellulaire élastique 8.The slide shown in the figures includes a body 1 having, at its upper part, a gutter 2 with a slot 4 and delimited by a fixed jaw 3 and a movable jaw 5, the latter being articulated on an axis 6 and being extended by a movable heel 7 inside the body 1 against the action of an elastic means formed here by a thickness of elastic cellular plastic 8.

Dans le talon 7 est pratiquée une lumière 10 délimitée par des surfaces de guidage 13 et 14 pour un poussoir 11 monté coulissant dans ladite lumière contre l'action des moyens élastiques 8.In the heel 7 is made a light 10 delimited by guide surfaces 13 and 14 for a pusher 11 mounted sliding in said light against the action elastic means 8.

Le poussoir 11 est accessible de l'extérieur à travers la lumière 10 de la partie inférieure de la mâchoire 5 et présente, sur sa face tournée vers le bas, une échancrure 12 et sur sa face opposée, une entaille 16.The pusher 11 is accessible from the outside through the lumen 10 of the lower part of the jaw 5 and presents, on its face facing down, a notch 12 and on its opposite face, a notch 16.

L'axe 6 est supporté par des paliers 17 prévus dans des joues 18 du corps 1.The axis 6 is supported by bearings 17 provided in cheeks 18 of body 1.

Le corps 1 est pourvue de deux fentes 19 dans lesquelles s'insèrent des pattes 20 solidaires d'une poignée 21 destinée à recevoir un mousqueton solidaire de l'une des extrémités d'une longe dont l'autre extrémité est fixée à un harnais de sécurité porté par un utilisateur.The body 1 is provided with two slots 19 in which insert legs 20 integral with a handle 21 intended to receive a carabiner secured to one end of a lanyard whose other end is attached to a safety harness worn by a user.

Les pattes 20 sont solidaires d'un axe 25 qui passe à travers un canal 26 du talon 7 et qui, à ses extrémités, est guidé dans des cames 27 des joues 18, le fond du canal 26 étant garni d'une épaisseur 28 de matière plastique élastique afin de constituer un élément élastique tendant à maintenir l'axe 25 dans une position intermédiaire dans laquelle il bute contre le poussoir 11. The legs 20 are integral with an axis 25 which passes through a channel 26 of the heel 7 and which, at its ends, is guided in cams 27 of cheeks 18, the bottom of the channel 26 being filled with a thickness 28 of plastic material elastic in order to constitute an elastic element tending to maintain the axis 25 in an intermediate position in which it abuts against the pusher 11.

Le canal 26 est incliné par rapport à la verticale de manière que son fond soit plus rapproché des moyens élastiques 8 que son extrémité supérieure.Channel 26 is inclined relative to the vertical so that its bottom is closer to the means elastic 8 as its upper end.

Les cames 27 sont inclinées en sens opposé par rapport au canal 26, le fond du canal 26 et l'extrémité inférieure de la came 27 coïncident dans une position dans laquelle la mâchoire 5 bute contre la mâchoire fixe 3, la fente 4 étant fermée.The cams 27 are inclined in the opposite direction with respect to at channel 26, the bottom of channel 26 and the lower end of cam 27 coincide in a position in which the jaw 5 abuts against the fixed jaw 3, the slot 4 being closed.

Comme représenté à la figure 3, le coulisseau est destiné à être utilisé sur une ligne de vie constituée par un câble, horizontal 30 s'étendant le long d'une paroi et supporte, par un étrier 31 monté contre ladite paroi et sur lequel sont fixées les pattes 33, un cavalier 32 traversé par le câble 31 et prolongé par des manchons tronconiques 34.As shown in Figure 3, the slider is intended to be used on a lifeline constituted by a horizontal cable 30 extending along a wall and supports, by a stirrup 31 mounted against said wall and on which are fixed the legs 33, a jumper 32 crossed by cable 31 and extended by sleeves tapered 34.

Le coulisseau peut occuper trois positions, une position intermédiaire (voir figures 1, 3 et 6) dans laquelle la mâchoire 5 est légèrement éloignée de la mâchoire 3 de manière à laisser subsister la fente 4, celle-ci ayant une largeur inférieure au diamètre du câble 30, mais légèrement supérieure à l'épaisseur des pattes 33 de manière que le coulisseau puisse passer librement sur le cavalier 32 moyennant un pivotement sur les manchons 34. Il est à noter que le coulisseau, selon l'invention, peut ainsi être utilisé aussi bien pour un déplacement dans un sens que dans l'autre puisque le corps 1 peut basculer librement aussi bien dans un sens ou dans l'autre que sur les pattes 20. The slide can occupy three positions, one position intermediate (see Figures 1, 3 and 6) in which jaw 5 is slightly away from jaw 3 by so as to leave the slot 4, the latter having a width less than cable diameter 30, but slightly greater than the thickness of the legs 33 so that the slide can pass freely on rider 32 by pivoting on the sleeves 34. It should be noted that the slide, according to the invention, can thus be used for both one-way and in the other since the body 1 can tilt freely as well in one way or the other as on the legs 20.

La seconde position du coulisseau est une position ouverte qui permet de monter le coulisseau sur le câble 30 (voir figures 2, 5 et 7), la mâchoire 5 étant basculée de manière que la fente 4 soit assez large pour permettre le passage à travers celle-ci du câble 30.The second position of the slide is a position open which allows the slide to be mounted on the cable 30 (see Figures 2, 5 and 7), the jaw 5 being tilted so that the slot 4 is wide enough to allow the passage through it of the cable 30.

Enfin, la troisième position est une position de sécurité (voir figure 8). Cette position est automatiquement obtenue si la poignée 21 est soumise à une traction en cas de chute par exemple et dans ce cas, la mâchoire 5 est serrée de manière à venir coopérer contre la mâchoire fixe 3, la fente 4 étant ainsi fermée.Finally, the third position is a safety position (see figure 8). This position is automatically obtained if the handle 21 is subjected to traction in the event drop for example and in this case the jaw 5 is tightened so as to cooperate against the jaw fixed 3, the slot 4 being thus closed.

Le coulisseau, par construction, occupe la première position et si on veut faire passer la mâchoire dans la seconde position, on appuie sur le poussoir 11 (voir figures 5 et 7), l'axe 25, poussé par le basculement vers le haut de la poignée 21, s'insère alors dans l'échancrure 12 en glissant dans le canal 26. Durant le glissement de l'axe 25 celui-ci est guidé par les cames 27 qui sont inclinées et commandent le basculement de la mâchoire 5 sur son axe 6.The slide, by construction, occupies the first position and if we want to move the jaw in the second position, press button 11 (see figures 5 and 7), axis 25, pushed by the tilting towards the top of the handle 21, then fits into the notch 12 by sliding in channel 26. During the sliding of the axis 25 this is guided by the cams 27 which are inclined and control the tilting of the jaw 5 on its axis 6.

Pour ramener le coulisseau vers la première position, il suffit de relâcher la poignée 21 et, sous l'action des moyens élastiques 8, l'axe 25 échappe l'échancrure 12, le poussoir revenant dans sa position initiale sous l'action de l'épaisseur de la matière élastique 8. On remarquera que, dans cette position intermédiaire, l'axe 25 est légèrement éloigné du fond du canal 26 grâce à l'épaisseur 28 (voir figure 6). Si une traction est appliquée sur la poignée 21 (voir figure 8), l'axe 25 est tiré vers le bas et comprime l'épaisseur souple et élastique 28 ; durant ce déplacement, la came 27 oblige le talon 7 à basculer dans le sens de la fermeture de la fente 4 correspondant à la position de sécurité.To bring the slide back to the first position, just release the handle 21 and, under the action of the elastic means 8, the axis 25 escapes the notch 12, the pusher returning to its position initial under the action of the thickness of the material elastic 8. Note that in this position intermediate, axis 25 is slightly away from the bottom of the channel 26 thanks to the thickness 28 (see FIG. 6). If one traction is applied to the handle 21 (see FIG. 8), axis 25 is pulled down and compresses the thickness flexible and elastic 28; during this movement, the cam 27 forces heel 7 to switch in the closing direction of the slot 4 corresponding to the safety position.

Lorsque la traction exercée sur la poignée 21 a cessé, le coulisseau revient automatiquement dans la position intermédiaire.When the traction exerted on the handle 21 has stopped, the slider automatically returns to the position intermediate.

On conçoit qu'un tel dispositif offre une grande sécurité et que son utilisation particulièrement simple permet d'éviter tout risque de mauvaise manoeuvre.We understand that such a device offers great security and that its particularly simple use allows to avoid any risk of improper operation.

Bien entendu, l'invention n'est pas limitée au mode de réalisation qui vient d'être décrit et représenté. On pourra y apporter de nombreuses modifications de détail sans sortir pour cela du cadre de l'invention.Of course, the invention is not limited to the mode of realization which has just been described and represented. We may make many detailed changes without departing from the scope of the invention.
