Description

La présente invention concerne un dispositif de sécurité de type assureur/descendeur, destiné à coopérer avec une corde, comprenant des moyens aptes à recevoir ladite corde et solidaires en rotation d'un châssis sur lequel sont montés en pivotement des moyens d'enserrement de ladite corde aptes à coopérer avec lesdits moyens de réception, lesdits moyens d'enserrement et le châssis comprenant en vis-à-vis en position d'enserrement un logement destiné à coopérer avec des moyens d'accrochage, notamment un mousqueton.The present invention relates to a safety device type insurer / descender, intended to cooperate with a rope, comprising means adapted to receive said rope and secured in rotation of a frame on which are pivotally mounted means for clamping said rope capable of cooperating with said receiving means, said gripping means and the frame comprising, facing each other in the gripping position, a housing intended to cooperate with attachment means, in particular a carabiner.

La présente invention entre dans le domaine de l'escalade, de l'alpinisme et analogue, en particulier elle concerne les dispositifs de sécurité destinés à assurer une personne. En outre, l'invention trouve aussi son application dans le sauvetage et l'évacuation de personne.The present invention is in the field of climbing, mountaineering and the like, in particular it relates to safety devices for ensuring a person. In addition, the invention also finds application in the rescue and evacuation of person.

L'escalade et l'alpinisme sont des sports à risque qui nécessite prudence et attention, tout en respectant des règles de sécurité strictes. Le matériel utilisé subit sans cesse des modifications pour améliorer leur résistance, pour simplifier leur utilisation, pour diminuer leur poids, etc.Climbing and mountaineering are risky sports that require caution and attention, while respecting strict safety rules. The equipment used constantly undergoes modifications to improve their resistance, to simplify their use, to reduce their weight, etc.

La présente invention entre dans le cadre de cette amélioration et concerne donc un dispositif de sécurité, en particulier de type descendeur, assureur ou analogue.The present invention falls within the scope of this improvement and therefore relates to a safety device, in particular of descender, insurer or the like type.

Un descendeur permet à une personne de s'assurer elle-même sur une corde en vue de descendre le long d'une paroi, mur, dévers ou autre. Un descendeur connu est le descendeur en huit en raison de sa forme et est souvent utilisé pour la descente dite en rappel. Très simple d'utilisation, il nécessite le maintien par le grimpeur de la corde, ou du brin libre de la corde, et ne permet toutefois pas le blocage de la corde en cas de chute ou en cas de lâcher de la corde par la personne. Un tel descendeur est polyvalent et peut aussi servir à assurer une personne escaladant ou descendant une paroi. Il présente toutefois le même inconvénient de ne pas bloquer la corde si cette dernière est lâchée par la personne qui assure le grimpeur (voir par example le document GB 2 044 414 ).A chute allows a person to secure himself on a rope in order to descend along a wall, wall, overhang or other. A known descender is the descender in eight because of its shape and is often used for so-called abseiling. Very easy to use, it requires the climber to keep the rope, or the free end of the rope, and does not allow the rope to be locked in case of fall or if the rope is dropped by the person . Such chute is versatile and can also be used to ensure a person climbing or descending a wall. However, it has the same disadvantage of not locking the rope if it is released by the person who assures the climber (see for example the document GB 2 044 414 ).

Le bloqueur résout notamment ce problème en bloquant la corde sous l'action du grimpeur. Un tel dispositif comprend généralement une gâchette pour l'actionner et un évidement denté pour assurer l'immobilisation sur une corde. Le bloqueur est tout de même destiné à permettre la remontée le long d'une corde.The blocker solves this problem by blocking the rope under the action of the climber. Such a device generally comprises a trigger for actuating it and a toothed recess for immobilizing on a rope. The blocker is still intended to allow the rise along a rope.

C'est pourquoi l'état de la technique comprend encore des systèmes d'assurage de type assureur et plaquette, destinés à assurer en toute sécurité l'escalade ou la descente d'un grimpeur par une autre personne. Ces systèmes d'assurage ont pour particularité d'être utilisés en combinaison avec un mousqueton de sécurité, notamment à vis ou à fermeture automatique.This is why the state of the art still includes insurer and wafer type belay systems, designed to ensure the safe climbing or descent of a climber by another person. These belaying systems have the particularity to be used in combination with a carabiner security, including screw or automatic closure.

De formes et d'utilisations multiples, ces systèmes d'assurage comprennent en particulier un assureur/descendeur autobloquant et autofreinant. Un tel dispositif permet le blocage en cas de chute dès qu'une tension importante intervient sur la corde, sans pour autant nécessiter le maintien du brin libre de cette dernière. Pour ce faire, ce dispositif comprend deux poulies à gorge destinée à recevoir la corde et est articulé de manière à s'ouvrir en deux parties, par pivotement suivant l'axe de rotation d'une desdites poulies, pour permettre l'engagement de ladite corde. Les deux parties comprennent un orifice ménagé en vis-à-vis l'une de l'autre en position fermée en vue de recevoir un mousqueton. L'une desdites poulie est montée apte à pivoter sur son axe de manière à pincer la corde, arrêtant ainsi son défilement. Une poignée sert à débloquer la corde afin de permettre la descente dite en moulinette, par freinage de la corde mais il est alors nécessaire de maintenir le brin libre de la corde.Of multiple forms and uses, these belay systems include in particular a self-locking and self-braking insurer / descender. Such a device allows blocking in case of a fall as soon as a large tension occurs on the rope, without requiring the maintenance of the free strand of the latter. To do this, this device comprises two grooved pulleys for receiving the rope and is articulated so as to open in two parts, by pivoting along the axis of rotation of one of said pulleys, to allow the engagement of said rope. The two parts comprise an orifice formed vis-à-vis one another in the closed position to receive a carabiner. One of said pulley is mounted pivotable on its axis so as to pinch the rope, thus stopping its scroll. A handle is used to unlock the rope to allow the so-called roping, braking rope but then it is necessary to maintain the free strand of the rope.

Un tel dispositif est toutefois limité à l'escalade en salle ou en falaise, dans un lieu déjà bien équipé en matière de moyens de sécurité.Such a device is however limited to climbing in the room or cliff, in a place already well equipped in terms of security.

Un autre inconvénient des dispositifs de l'état de la technique est la possibilité pour la corde de glisser, les forces de frottements n'étant plus assez élevées pour contrer le poids lors d'une chute. De plus, l'arrêt en cas de chute est souvent brutal et net, pouvant ainsi occasionner un choc du grimpeur sur la paroi.Another disadvantage of the devices of the state of the art is the possibility for the rope to slide, the friction forces are no longer high enough to counter the weight during a fall. In addition, stopping in case of a fall is often brutal and sharp, and may cause a shock climber on the wall.

La présente invention a pour but de pallier les inconvénients de l'état de la technique en proposant un dispositif de sécurité de type assureur/descendeur simple d'utilisation et rapide à mettre en place, léger et apportant une sécurité optimale. En particulier, il permet de réguler la vitesse de descente par rapport à la corde. De plus, l'assureur/descendeur selon l'invention empêche tout glissement de la corde et évite les arrêts brusques en cas de chute.The present invention aims to overcome the disadvantages of the state of the art by providing a safety device insurer / descender type easy to use and quick to implement, lightweight and providing optimal security. In particular, it makes it possible to regulate the speed of descent with respect to the rope. In addition, the insurer / descender according to the invention prevents slippage of the rope and avoids sudden stops in case of a fall.

Pour ce faire, l'invention concerne un dispositif de sécurité de type assureur/descendeur, destiné à coopérer avec une corde, comprenant des moyens aptes à recevoir ladite corde et solidaires en rotation d'un châssis sur lequel sont montés en pivotement des moyens d'enserrement de ladite corde aptes à coopérer avec lesdits moyens de réception, lesdits moyens d'enserrement et le châssis comprenant en vis-à-vis en position d'enserrement un logement apte à coopérer avec des moyens d'accrochage, notamment un mousqueton, caractérisé par le fait que lesdits moyens de réception se présentent sous la forme d'une poulie enfermant des moyens aptes à réguler sa vitesse de rotation.To do this, the invention relates to a safety device of the insurer / descender type, intended to cooperate with a rope, comprising means adapted to receive said rope and secured in rotation to a frame on which are pivotally mounted means of gripping said rope capable of cooperating with said receiving means, said gripping means and the frame comprising, facing a gripping position, a housing adapted to cooperate with fastening means, in particular a carabiner, characterized in that said receiving means is in the form of a pulley enclosing means adapted to regulate its speed of rotation.

Selon d'autres caractéristiques de l'invention, les moyens aptes à réguler la vitesse de rotation de la poulie comprennent des moyens de démultiplication de vitesse aptes à asservir l'accroissement du ralentissement de ladite poulie à l'accroissement de la vitesse de rotation de celle-ci.According to other characteristics of the invention, the means able to regulate the speed of rotation of the pulley comprise gear reduction means capable of controlling the increase of the slowing down of said pulley with the increase of the speed of rotation of the pulley. it.

De préférence, les moyens de démultiplication consistent en un train épicycloïdal.Preferably, the reduction means consist of an epicyclic gear train.

De manière particulière, les moyens de démultiplication comprennent un porte satellite monté en rotation par rapport à ladite poulie et supportant au moins un satellite denté double coopérant par engrènement, d'une part, avec une couronne dentée solidaire de ladite poulie, et, d'autre part, avec une couronne dentée solidaire dudit châssis, les dentures desdites couronnes étant conformées de sorte que le rapport d'engrènement entre chacune desdites couronnes entraîne le porte satellite à une vitesse différente de la vitesse de rotation de la poulie.In particular, the reduction means comprise a satellite carrier rotatably mounted relative to said pulley and supporting at least one double toothed satellite cooperating meshing, on the one hand, with a ring gear integral with said pulley, and, on the other hand, with a ring gear secured to said frame, the teeth of said rings being shaped so that the meshing ratio between each of said rings drives the satellite gate at a speed different from the speed of rotation of the pulley.

De plus, le porte satellite comprend les moyens de freinage de la poulie par friction et/ou au travers d'un fluide.In addition, the satellite gate comprises means for braking the pulley by friction and / or through a fluid.

Selon un mode de réalisation, les moyens de freinage comprennent au moins une masselotte libre en translation radialement par rapport à la poulie et apte à coopérer par frottement sur une piste ménagée à l'intérieure de ladite poulie.According to one embodiment, the braking means comprise at least one flyweight free in translation radially relative to the pulley and adapted to cooperate by friction on a track formed inside said pulley.

Avantageusement, les moyens d'enserrement s'étendent sur tout ou partie de la périphérie de la poulie de manière à maintenir la corde dans ladite gorge et empêcher son glissement dans celle-ci.Advantageously, the gripping means extend over all or part of the periphery of the pulley so as to maintain the rope in said groove and prevent slipping therein.

Préférentiellement, les moyens d'enserrement comprennent au moins une poulie destinée à coopérer avec la corde et montée en rotation dans un espace prévu pour le passage de ladite corde.Preferably, the clasping means comprise at least one pulley intended to cooperate with the rope and mounted in rotation in a space provided for the passage of said rope.

De plus, le logement est opposé diamétralement aux moyens empêchant le glissement de la corde.In addition, the housing is diametrically opposed to the means preventing slippage of the rope.

L'invention concerne aussi une corde combinée au dispositif précédent, caractérisée par le fait qu'elle est agencée en boucle.The invention also relates to a rope combined with the preceding device, characterized in that it is arranged in a loop.

Dans un mode particulier d'assujettissement sur la corde 2 du dispositif de sécurité 1, ladite corde 2 est agencée en boucle, à savoir que ses extrémités sont reliées entre elles. De cette manière, il est alors possible de faire tourner la corde 2 à l'infini au travers dudit dispositif 1, sans jamais la remontée, ce qui s'avère utile lors du sauvetage de plusieurs personnes à la suite. En particulier, le dispositif de sécurité 1 peut être fixé à un point fixe et servir de simple poulie qui régule alors la vitesse de descente de la personne accrochée à la corde 2.In a particular mode of securing on the rope 2 of the safety device 1, said rope 2 is arranged in a loop, namely that its ends are interconnected. In this way, it is then possible to rotate the rope 2 to infinity through said device 1, without ever the ascent, which is useful when rescuing several people in a row. In particular, the safety device 1 can be fixed at a fixed point and serve as a simple pulley which then regulates the speed of descent of the person hooked to the rope 2.

Par conséquent, ledit dispositif de sécurité 1 comprend des moyens 5 aptes à recevoir ladite corde 2. Ces moyens de réception 5 sont solidaires en rotation d'un châssis 6 et se présentent préférentiellement sous la forme d'une poulie 7, cette dernière comportant une gorge 8 conformée de manière à coopérer avec ladite corde 2. Ladite poulie 7 est montée en rotation libre sur un axe 9 sur ledit châssis 6.Therefore, said safety device 1 comprises means 5 adapted to receive said rope 2. These receiving means 5 are integral in rotation with a frame 6 and are preferably in the form of a pulley 7, the latter comprising a 8 groove shaped to cooperate with said rope 2. Said pulley 7 is mounted in free rotation on an axis 9 of said frame 6.

Des moyens 10 d'enserrement de ladite corde 2 sont montés en pivotement sur ledit châssis 6. Ces moyens d'enserrement 10 sont aptes à coopérer avec les moyens de réception 5, en particulier de manière à bloquer la corde 2 dans la gorge de la poulie 7 pour empêcher son glissement par rapport à cette dernière. Pour ce faire, comme visible sur les figures 1 et 2, les moyens d'enserrement 10 peuvent se présenter sous la forme d'un arc 11 articulé sur ledit châssis 6, en outre en rotation mais il peut être prévu de l'assujettir par d'autre moyens d'articulation et/ou de fixation, par exemple par clipsage.Means 10 for gripping said rope 2 are pivotally mounted on said frame 6. These gripping means 10 are able to cooperate with the receiving means 5, in particular so as to block the rope 2 in the groove of the pulley 7 to prevent slippage with respect thereto. To do this, as visible on the Figures 1 and 2 , the clamping means 10 can be in the form an arc 11 hinged to said frame 6, further in rotation but it may be provided to secure it by other means of articulation and / or fixing, for example by clipping.

De manière toute particulière, le châssis 6 et les moyens d'enserrement 10 comprennent en vis-à-vis un logement 12 destiné à coopérer avec des moyens d'accrochage, non représentés, notamment un mousqueton. Ce logement 12 est conformé de manière à permettre le passage du mousqueton en position d'ouverture de ce dernier. Une fois le mousqueton enfilé, le châssis 6 et les moyens d'enserrement 10 sont bloqués et solidarisés entre eux.In a very particular way, the frame 6 and the clasping means 10 comprise, in facing relation, a housing 12 designed to cooperate with hooking means, not shown, in particular a carabiner. This housing 12 is shaped to allow the passage of the carabiner in the open position of the latter. Once the carabiner is threaded, the frame 6 and the clasping means 10 are locked and secured to each other.

Cette agencement particulier d'une poulie 7 en rotation sur un châssis 6, supportant les moyens d'enserrement 10 en pivotement, permet d'assujettir très simplement le dispositif de sécurité 1 directement sur la corde 2, sans être obligé de nouer un extrémité de la corde 2, de la lover, etc.This particular arrangement of a pulley 7 rotated on a frame 6, supporting the pivoting means 10, makes it possible to easily secure the safety device 1 directly on the rope 2, without having to tie an end of rope 2, lover, etc.

Une caractéristique du dispositif 1 selon l'invention réside dans la régulation de la vitesse de descente d'une personne assurée au travers dudit dispositif de sécurité 1. Pour ce faire, lesdits moyens de réception 5 enferment des moyens 13 aptes à réguler la vitesse de rotation de ladite poulie 7. Ces moyens de régulation 13 comprennent des moyens 14 de démultiplication de vitesse aptes à asservir l'accroissement du ralentissement de ladite poulie 7 à l'accroissement de la vitesse de rotation de celle-ci. Les moyens de démultiplication 14 consistent préférentiellement en un train épicycloïdal, particulièrement visible en vue éclatée sur le mode de réalisation de la figure 5. La poulie 7 sert alors de cage audit train épicycloïdal.A feature of the device 1 according to the invention lies in the regulation of the descent rate of a person insured through said safety device 1. To do this, said receiving means 5 enclose means 13 able to regulate the speed of rotation of said pulley 7. These regulating means 13 comprise means 14 of gear reduction capable of slaving the increased slowing of said pulley 7 to increase the speed of rotation thereof. The demultiplication means 14 preferably consist of an epicyclic gear train, which is particularly visible in an exploded view of the embodiment of the invention. figure 5 . The pulley 7 then serves as a cage to said epicyclic train.

A ce propos, en référence à la figure 4 sur laquelle est représenté un mode simplifié de réalisation de l'invention, les moyens de démultiplication 14 comprennent un porte satellite 15 monté en rotation par rapport à ladite poulie 7, en particulier sur l'axe 9 solidaire dudit châssis 6. Ainsi, le porte satellite 15 est libre en rotation par rapport à la poulie 7 et par rapport audit châssis 6. Ce porte satellite 15 supporte au moins un satellite 16, monté en rotation sur un axe 17. Dans le mode préférentiel de réalisation de l'invention, les satellites 16 sont au nombre de trois montés respectivement sur trois axes 17 solidaires dudit porte satellite 15. Dans ce cas, les satellites 16 sont libres les uns par rapport aux autres.In this connection, with reference to figure 4 on which is represented a simplified embodiment of the invention, the reduction means 14 comprise a satellite door 15 mounted in rotation relative to said pulley 7, in particular on the axis 9 secured to said frame 6. Thus, the satellite door 15 is free to rotate relative to the pulley 7 and relative to said frame 6. This satellite holder 15 supports at least one satellite 16, mounted in rotation on an axis 17. In the preferred embodiment of the invention, the satellites 16 are three mounted respectively on three axes 17 integral with said satellite door 15. In this case, the satellites 16 are free from each other.

De manière toute particulière, un satellite 16 est prévu denté et double coopérant ainsi par engrènement, d'une part, avec une denture 18A ménagée sur une piste s'étendant sur le pourtour intérieur de ladite poulie 7, et, d'autre part, avec une denture 19A ménagée sur une piste s'étendant sur le pourtour intérieur dudit châssis 6.In a very particular way, a satellite 16 is provided toothed and double thus cooperating by meshing, on the one hand, with a toothing 18A formed on a track extending on the inner periphery of said pulley 7, and, on the other hand, with a toothing 19A formed on a track extending on the inner periphery of said frame 6.

Il convient de noter que le châssis 6 est monté en rotation par rapport à ladite poulie 7 au travers d'un roulement 20 réalisé entre ladite poulie 7 et le châssis 6. De préférence et comme visible sur le mode de réalisation de la figure 3, une couronne de roulement 21 est fixée sur ladite poulie 7 pour refermer ledit roulement 20. Suivant un autre mode de réalisation, cette couronne 21 pourrait être fixée sur ledit châssis 6.It should be noted that the frame 6 is rotatably mounted relative to said pulley 7 through a bearing 20 formed between said pulley 7 and the frame 6. Preferably and as visible in the embodiment of the figure 3 , a bearing ring 21 is fixed on said pulley 7 to close said bearing 20. According to another embodiment, this ring 21 could be fixed on said frame 6.

Les dentures 18A et 19A sont conformées de sorte que le rapport d'engrènement entre chacune desdites dentures 18A et 19A entraîne le porte satellite 15 à une vitesse différente de la vitesse de rotation de la poulie 7. En effet, le nombre de dent de chaque denture 18A et 19A est différent. On notera qu'un satellite 16 est prévu double avec deux dentures identiques 22 et 23 conformées pour coopérer respectivement avec lesdites dentures 18A et 19A. De plus, dans le cas de plusieurs satellites 16, ces derniers ne sont pas engrenés entre eux. Ainsi un satellite 16 devrait mettre plus de temps à parcourir une desdites denture 18A (ou 19A) que l'autre denture 19A (respectivement 18A). Or, les dentures 22 et 23 d'un satellite 16 étant solidaires, cette différence se traduit par un différentiel de vitesse de rotation et l'entraînement dudit porte satellite 15. De cette manière, le rapport d'engrènement entre chacune desdites dentures 18A et 19A entraîne le porte satellite 15 à une vitesse différente de la vitesse de rotation de la poulie 7.The teeth 18A and 19A are shaped so that the meshing ratio between each of said teeth 18A and 19A drives the satellite door 15 at a speed different from the speed of rotation of the pulley 7. In effect, the number of teeth of each Teeth 18A and 19A are different. Note that a satellite 16 is provided double with two identical teeth 22 and 23 shaped to cooperate respectively with said teeth 18A and 19A. In addition, in the case of several satellites 16, the latter are not meshed with each other. Thus a satellite 16 should take longer to traverse one of said teeth 18A (or 19A) than the other toothing 19A (respectively 18A). However, the teeth 22 and 23 of a satellite 16 being integral, this difference results in a rotation speed differential and the drive of said satellite carrier 15. In this way, the meshing ratio between each of said teeth 18A and 19A drives the satellite gate 15 at a speed different from the speed of rotation of the pulley 7.

Dans le mode de réalisation préférentiel de l'invention, les dentures 18A et 19A sont remplacées respectivement par une couronne 18B dentée solidaire de ladite poulie 7, et, d'autre part, par une couronne 19B dentée solidaire dudit châssis 6. Ces couronnes 18B et 19B sont amovibles et fixées au travers de moyens de fixation, par exemple par vissage de vis au travers d'alésages 24 visibles sur les figures 3 et 5.In the preferred embodiment of the invention, the teeth 18A and 19A are replaced respectively by a toothed crown 18B integral with said pulley 7, and, secondly, by a toothed ring 19B integral with said frame 6. These rings 18B and 19B are removable and fixed through fastening means, for example by screwing screws through holes 24 visible on the figures 3 and 5 .

Avantageusement, les moyens de régulation 13 comprennent des moyens 25 de freinage de la poulie 7. Selon le mode préférentiel de réalisation de l'invention, représenté sur les dessins, le freinage s'opère par friction. En particulier, ces moyens de freinage 25 par friction sont compris dans le porte satellite et comprennent au moins une masselotte 26 libre en translation radialement par rapport à la poulie 7. Comme visible sur les figures 3 et 4, cette masselotte 26 glisse dans un logement 27 sous l'effet de la force centrifuge due à la rotation du porte satellite 15. La masselotte 26 est alors expulsée vers l'extérieur dudit logement 27 et coopère par frottement sur une piste 28 ménagée à l'intérieur de ladite poulie 7.Advantageously, the regulation means 13 comprise means 25 for braking the pulley 7. According to the preferred embodiment of the invention, shown in the drawings, the braking takes place by friction. In particular, these friction braking means are included in the satellite carrier and comprise at least one flyweight 26 which is free to translate radially relative to the pulley 7. figures 3 and 4 this flyweight 26 slides in a housing 27 under the effect of the centrifugal force due to the rotation of the satellite carrier 15. The flyweight 26 is then expelled outwardly of said housing 27 and frictionally engages a track 28 formed at the inside said pulley 7.

Lors d'une rotation lente de la poulie 7, la masselotte 26 ne sort que peu ou pas du logement 27, le porte satellite ayant une vitesse sensiblement identique à celle de la poulie 7. Par contre, l'effet démultiplicateur du train épicycloïdal accélère le porte satellite 15 de sorte que la masselotte 26 sort davantage du logement 27 et entre en contact avec la poulie 7, freinant alors cette dernière.During a slow rotation of the pulley 7, the flyweight 26 leaves little or no housing 27, the satellite carrier having a speed substantially identical to that of the pulley 7. By cons, the multiplier effect of the epicyclic gear accelerates the satellite door 15 so that the feeder 26 comes out further housing 27 and comes into contact with the pulley 7, thereby braking the latter.

Comme visible sur la figure 5, le porte satellite 15 comprend plusieurs, de préférence trois, masselottes 26 destinées à chacune s'insérer dans un logement 27.As visible on the figure 5 , the satellite gate 15 comprises several, preferably three, weights 26 each intended to fit into a housing 27.

Selon un autre mode de réalisation, non représenté, le freinage peut s'opérer au travers de la résistance de l'entraînement de la poulie 7 au travers d'un fluide, en particulier de l'huile ou analogue. Pour ce faire, tout ou partie de la poulie 7 peut être plongé dans ledit fluide, ladite poulie étant alors prévue étanche.According to another embodiment, not shown, the braking can take place through the resistance of the driving of the pulley 7 through a fluid, in particular oil or the like. To do this, all or part of the pulley 7 can be immersed in said fluid, said pulley then being sealed.

Selon encore un autre mode de réalisation, les moyens de freinage 25 par friction peuvent être combinés au freinage au travers d'un fluide pour augmenter le ralentissement de la poulie 7.According to yet another embodiment, the friction brake means 25 may be combined with braking through a fluid to increase slowing of the pulley 7.

Une autre particularité du dispositif de sécurité 1 selon l'invention, réside dans le fait que la corde 2 ne glisse pas, même sous l'effet d'une forte charge ou d'une accélération brutale et/ou prolongée.Another feature of the safety device 1 according to the invention lies in the fact that the rope 2 does not slip, even under the effect of a heavy load or a sudden and / or prolonged acceleration.

Pour ce faire, les moyens d'enserrement 10 s'étendent sur tout ou partie de la périphérie de la poulie 7 de manière à maintenir la corde 2 dans ladite gorge 8 et empêcher son glissement dans celle-ci. En particulier, l'arc 11 s'étend autour de la poulie 7 le long sensiblement de la moitié de son périmètre.To do this, the gripping means 10 extend over all or part of the periphery of the pulley 7 so as to maintain the rope 2 in said groove 8 and prevent slipping therein. In particular, the bow 11 extends around the pulley 7 along substantially half of its perimeter.

Dans un mode de réalisation non représenté, les moyens d'enserrement 10 peuvent comprendre deux arcs amovibles l'un par rapport à l'autre et tous les deux montés en pivotement sur ledit châssis 6 à une de leur extrémité. Ces arcs comprennent chacun au niveau de leur extrémité opposée un orifice pour former le logement 12 destiné à recevoir le mousqueton, en combinaison avec l'orifice du châssis 6.In an embodiment not shown, the clasping means 10 may comprise two removable arcs relative to each other and both pivotally mounted on said frame 6 at one end. These arcs each comprise at their opposite end an orifice for forming the housing 12 for receiving the carabiner, in combination with the hole of the frame 6.

Comme visible sur les figures 1 et 2, les moyens d'enserrement 10 comprennent au moins une galet 29 destiné à coopérer avec la corde 2 et monté en rotation dans un espace 30 prévu pour le passage de ladite corde 2. De préférence, les moyens d'enserrement 10 comprennent deux galets 29 montés en rotation de part et d'autre de l'espace 30 et formant des moyens empêchant le glissement de la corde 2.As visible on Figures 1 and 2 , the clasping means 10 comprise at least one roller 29 intended to cooperate with the rope 2 and rotatably mounted in a space 30 provided for the passage of said rope 2. Preferably, the clasping means 10 comprise two rollers 29 mounted in rotation on either side of the space 30 and forming means preventing the rope 2 from sliding.

Les brins 3 et 4 de la corde 2 sont destinés à s'appuyer sur chaque galet 29 qui appuie sur la corde 2 enfoncée dans la gorge 8 de la poulie 7. Le galet 29 améliore le déplacement de la corde 2 et empêche le frottement de cette dernière sur le dispositif 1, évitant une usure prématurée. De plus, la corde 2 sort de la gorge 8 sensiblement perpendiculairement, empêchant alors le glissement de la corde 2 en sortie de poulie 7.The strands 3 and 4 of the rope 2 are intended to rest on each roller 29 which presses the rope 2 pressed into the groove 8 of the pulley 7. The roller 29 improves the movement of the rope 2 and prevents the friction of the latter on the device 1, avoiding premature wear. In addition, the rope 2 leaves the groove 8 substantially perpendicularly, thus preventing the rope 2 from sliding out of the pulley 7.

Il convient de noter que les parois de la gorge 8 peuvent être prévues rugueuses ou non lisses, de préférence avec des aspérités, dentures ou autre, améliorant l'accroche de la corde 2 sur ladite poulie 7.It should be noted that the walls of the groove 8 can be provided rough or non-smooth, preferably with asperities, teeth or other, improving the grip of the rope 2 on said pulley 7.

De plus, le logement d'accrochage 12 est opposé diamétralement aux moyens empêchant le glissement de la corde 2, comme visible sur les figures 1 et 2. Cette position particulière permet audit dispositif de sécurité 1 d'être accroché à un point fixe et jouer le rôle classique d'une poulie.In addition, the attachment housing 12 is diametrically opposed to the means preventing the sliding of the rope 2, as visible on the Figures 1 and 2 . This particular position allows said safety device 1 to be hooked to a fixed point and play the classic role of a pulley.

Enfin, ce dispositif de sécurité 1 peut être réalisé en tout matériau présentant les caractéristiques de légèreté et de solidité requises, notamment en métal.Finally, this safety device 1 can be made of any material having the characteristics of lightness and strength required, especially metal.

Le dispositif de sécurité 1 selon l'invention permet donc de réguler la vitesse de descente d'une personne assurée tout en permettant un assujettissement simple, sûr et rapide.The safety device 1 according to the invention thus makes it possible to regulate the speed of descent of an insured person while allowing a simple, safe and fast subjection.
