Description

Appareil d'assurage et de rappel pour corde simple ou double Belay and rappel device for single or double rope
Domaine technique de l'inventionTechnical field of the invention
L'invention est relative à un dispositif d'assurage pour corde comprenant : un corps métallique ayant au moins une fente pour le passage d'une boucle de corde, un élément de retenue solidaire du corps sans être articulé à ce dernier, et destiné à contrôler le mouvement relatif d'éloignement du corps par rapport à un mousqueton traversant ladite boucle.The invention relates to a belay device for rope comprising: a metal body having at least one slot for the passage of a rope loop, a retaining element integral with the body without being articulated to the latter, and intended for controlling the relative movement of the body away from a carabiner through said loop.
Ce type d'appareil de sécurité est destiné à accompagner et sécuriser révolution des grimpeurs, notamment lors de la progression du premier de cordée qui est assuré par le second grimpeur en cas de chute. Il peut également servir à assurer le second de cordée lorsque le premier de cordée aura atteint un point sécurisé. Outre les fonctions d'assurance du premier ou du second de cordée, l'appareil permet également de descendre en rappel assurant la sécurité du descendeur en lui permettant de freiner son allure.This type of safety device is designed to accompany and secure revolution climbers, especially during the progression of the first rope that is provided by the second climber in case of a fall. It can also be used to ensure the second roped when the leader of the rope has reached a secure point. In addition to the insurance functions of the first or second roped, the device also allows rappelling to ensure the safety of the descender by allowing it to slow down its pace.
État de la techniqueState of the art
II existe un premier type de plaquettes d'assurage en forme de tube à une ou deux fentes, le tube étant fixé à une anse de retenue. Lors du coulissement de la corde en service normal, la présence de l'anse évite l'éloignement du corps par rapport à un mousqueton traversant ladite boucle, mais le mousqueton peut se déplacer à l'intérieur de l'ouverture définie par l'anse. En cas de chute du premier de cordée, le mousqueton est plaqué contre le corps lors du blocage de la corde. Une action manuelle de déblocage est alors nécessaire pour libérer la corde, ce qui n'est pas toujours facile pour l'assureur en présence d'une corde mouillée, et avec des mains gantées.There is a first type of belay inserts in the form of a tube with one or two slots, the tube being attached to a retaining loop. When sliding the rope in normal operation, the presence of the handle prevents the body from moving away from a carabiner through said loop, but the carabiner can move within the opening defined by the handle . In the event of the first roped off, the carabiner is pressed against the body when the rope is blocked. A manual unlocking action is then necessary to release the rope, which is not always easy for the insurer in the presence of a wet rope, and with gloved hands.
Un deuxième type de plaquettes d'assurage utilise une plaquette à deux fentes, sur laquelle est serti un ressort hélicoïdal. Le mousqueton traverse une ou deux boucles selon que la corde est simple ou double, et vient comprimer le ressort lors du blocage. Le déblocage de la corde intervient par la détente du ressort après disparition de l'effort de traction sur la corde, mais l'absence de maintien du corps favorise son éloignement par rapport au mousqueton.A second type of belay pad uses a two-slot plate on which a coil spring is crimped. The carabiner passes through one or two loops depending on whether the rope is single or double, and compresses the spring during blocking. The unblocking of the rope intervenes by the relaxation of the spring after disappearance of the tensile force on the rope, but the absence of maintenance of the body favors its removal from the carabiner.
Il existe également un appareil d'assurage dénommé Toucan ayant un fiasque mobile articulé sur le corps fixe de l'appareil, de manière à pouvoir basculer entre une position rapprochée et une position déployée. La distance relative du corps par rapport au mousqueton d'attache traversant ladite boucle, n'est pas optimisée lorsque le flasque se trouve en position déployée.There is also a belay device called Toucan having a mobile flap hinged to the fixed body of the device, so as to switch between a close position and an extended position. The relative distance of the body relative to the fastening carabiner through said loop, is not optimized when the flange is in the deployed position.
Objet de l'inventionObject of the invention
L'objet de l'invention consiste à réaliser un dispositif d'assurage polyvalent permettant de combiner sur le même appareil les fonctions de déblocage de la corde et de maintien du corps de l'appareil, de manière à obtenir une sécurité d'assurage optimum.The object of the invention is to provide a versatile belay device for combining on the same device the functions of unlocking the rope and maintaining the body of the device, so as to obtain optimum security belay .
Le dispositif d'assurage selon l'invention est caractérisé en ce que comporte de plus des moyens élastiques agencés pour rapprocher le corps du mousqueton lors d'un blocage de la corde, et à l'en écarter automatiquement lors du déblocage. Les moyens élastiques peuvent être solidaires de l'élément de retenue, ou être séparés de ce dernier en étant attachés directement au corps.The belay device according to the invention is characterized in that further comprises elastic means arranged to bring the body of the carabiner during a locking of the rope, and to depart automatically when unlocking. The elastic means may be integral with the retaining element, or be separated from the latter by being attached directly to the body.
Selon un mode de réalisation préférentiel, l'élément de retenue est réalisé au moyen d'une matière souple constituant lesdits moyens élastiques, et est doté d'un organe d'attache et/ou d'une pièce de maintien du mousqueton. Le corps métallique à une ou deux fentes peut être formé par une plaquette tubulaire, ou un flasque central sur lequel est rapporté un étrier en U.According to a preferred embodiment, the retaining element is made by means of a flexible material constituting said elastic means, and is provided with an attachment member and / or a holding part of the carabiner. The metal body with one or two slots may be formed by a tubular plate, or a central flange on which is reported a U-shaped stirrup.
L'élément de retenue peut être constitué par une anse élastique fixée au dispositif d'assurage pour permettre le maintien du mousqueton au voisinage du corps, et favoriser le déblocage de la corde en cas de diminution de la tension mécanique.The retaining element may be constituted by an elastic loop attached to the belay device to allow the maintenance of the carabiner in the vicinity of the body, and promote the release of the rope in case of decrease in mechanical tension.

En référence aux figures 1 et 2, un dispositif d'assurage 10 pour corde 11 comporte un corps 12 métallique agencé selon une plaquette tubulaire, laquelle est pourvue de deux fentes 13, 14 oblongues pour le passage de la corde. Les deux fentes 13, 14 sont parallèles, et disposées côte-à-côte en étant séparées l'une de l'autre par une paroi 15 intermédiaire.Referring to Figures 1 and 2, a belay device 10 for rope 11 comprises a metal body 12 arranged in a tubular plate, which is provided with two slots 13, 14 oblong for the passage of the rope. The two slots 13, 14 are parallel, and arranged side by side, being separated from one another by an intermediate wall.
Un élément de retenue 16 comporte une anse 17, dont les deux extrémités sont solidarisée au corps 12 par sertissage ou tout autre procédé de fixation.A retaining element 16 comprises a loop 17, whose two ends are secured to the body 12 by crimping or any other method of attachment.
L'anse 17 est située dans un plan s'étendant perpendiculairement à la face interne 18 du corps 12, et est réalisée au moyen d'une matière souple autorisant une déformation élastique lors du blocage de la corde 11. De préférence, l'anse 17 est réalisée au moyen d'une gaine en plastique très résistant, dans laquelle peut être intégrée une armature interne de renforcement. L'anse 17 peut également être constituée par un câble très souple.The handle 17 is situated in a plane extending perpendicular to the internal face 18 of the body 12, and is made by means of a flexible material allowing elastic deformation during the locking of the rope 11. Preferably, the handle 17 is made by means of a very resistant plastic sheath, in which can be integrated an internal reinforcing reinforcement. The handle 17 can also be constituted by a very flexible cable.
Un organe d'attache 19 se trouve à la partie médiane de l'anse 17 pour permettre la mise en place d'un mousqueton 20. L'organe d'attache 19 est formé à titre d'exemple par une spire 22 fermée intermédiaire disposée à l'intérieur de l'anse 17, et ayant un diamètre interne correspondant à la section du mousqueton 20. Ce dernier est maintenu sans jeu dans l'organe d'attache 19, et s'étend orthogonalement par rapport à l'anse 17. La spire 22 est conformée par un bracelet 23 serti sur l'anse 17.An attachment member 19 is located at the middle portion of the handle 17 to allow the introduction of a carabiner 20. The fastener 19 is formed by way of example by an intermediate closed turn 22 arranged inside the handle 17, and having an internal diameter corresponding to the section of the carabiner 20. The latter is held without play in the fastener 19, and extends orthogonally with respect to the handle 17 The turn 22 is shaped by a bracelet 23 crimped on the handle 17.
Le fonctionnement du dispositif d'assurage 10 selon les figures 1 et 2 est le suivant :The operation of the belay device 10 according to Figures 1 and 2 is as follows:
Une seule corde 11 est représentée sur la figure 2 après passage d'une boucle 21 de corde dans la fente 14. Le mousqueton 20 traverse la boucle 21 de la corde 11 , et est simultanément accroché à un anneau du baudrier de l'assureur.A single rope 11 is shown in Figure 2 after passage of a loop 21 of rope in the slot 14. The carabiner 20 passes through the loop 21 of the rope 11, and is simultaneously attached to a ring of the shoulder belt of the insurer.
Il est possible de faire usage d'une corde double (non représentée) après passage d'une deuxième boucle dans l'autre fente 13. Dans ce cas, le mousqueton 20 traverse les deux boucles juxtaposées de la corde double.It is possible to use a double rope (not shown) after passing a second loop in the other slot 13. In this case, the carabiner 20 passes through the two juxtaposed loops of the double rope.
Dans les deux cas, l'anse 17 constitue l'organe de liaison déformable entre le corps 12 et l'anneau du baudrier.In both cases, the handle 17 constitutes the deformable connecting member between the body 12 and the ring of the harness.
Lors d'une progression normale du premier de cordée, l'assureur qui est par exemple le second grimpeur, contrôle le libre coulissement de la corde 11 , car l'anse 17 reste dans la position écartée de la figure 1. Le mousqueton 20 reste également dans la position écartée en favorisant le libre coulissement de la corde 11. L'anse 17 maintient le mousqueton 20 dans cette position, mais sans l'éloigner du dispositif d'assurage 10. Le mouvement relatif d'éloignement du corps 12 par rapport au mousqueton 20 traversant la boucle 21 , est ainsi contrôlé.During a normal progression of the first rope, the insurer who is for example the second climber, controls the free sliding of the rope 11, because the handle 17 remains in the position removed from Figure 1. The carabiner 20 remains also in the remote position by promoting the free sliding of the rope 11. The handle 17 keeps the carabiner 20 in this position, but without moving away from the belay device 10. The relative movement of the body 12 relative to the relative distance at the carabiner 20 passing through the loop 21, is thus controlled.
En cas de chute du premier de cordée, la tension exercée sur le brin amont de la corde 11 (voir flèche F1), provoque le rapprochement du mousqueton 20 vers la face interne 18 du corps 12 suite à la déformation élastique de l'anse 17 (voir figure 2). L'effet de friction important exercé par la boucle 21 de la corde 11 sur le mousqueton 20 assure le blocage de la corde et l'arrêt immédiat de la chute du grimpeur.In the event of a fall of the rope leader, the tension exerted on the upstream end of the rope 11 (see arrow F1) causes the carabiner 20 to approach the inner face 18 of the body 12 following the elastic deformation of the handle 17. (see Figure 2). The strong friction effect exerted by the loop 21 of the rope 11 on the carabiner 20 ensures the locking of the rope and the immediate stop of the fall of the climber.
Après disparition de la tension, le déblocage de la corde 11 intervient ensuite automatiquement suite au rappel élastique de l'anse 17 vers la position écartée de la figure 1. La présence de l'anse 17 élastique du dispositif d'assurage 10 permet à la fois de maintenir le mousqueton 20 au voisinage du corps 12, et de favoriser le déblocage de la corde 11 en absence de tension mécanique. Le matériau de l'anse 17 est choisi pour autoriser la flexion bidirectionnelle entre les positions rapprochée (figure 2) et écartée (figure 1 ).After disappearance of the tension, the unlocking of the cord 11 then occurs automatically following the elastic return of the handle 17 to the position removed from FIG. The presence of the elastic loop 17 of the belay device 10 allows both to maintain the carabiner 20 in the vicinity of the body 12, and to promote the unlocking of the rope 11 in the absence of mechanical tension. The material of the loop 17 is chosen to allow bidirectional bending between the close positions (Figure 2) and spaced apart (Figure 1).
Les figures 3 à 8 montrent différentes variantes de réalisation. Les mêmes numéros de repères seront utilisés pour désigner des pièces identiques ou similaires.Figures 3 to 8 show different embodiments. The same reference numbers will be used to designate identical or similar parts.
Sur la figure 3, le mousqueton 20 est rendu solidaire de l'anse 17 au moyen d'une pièce de maintien 24, notamment en élastomère. Le mousqueton 20 est alors monté imperdable.In Figure 3, the carabiner 20 is secured to the handle 17 by means of a holding member 24, in particular elastomer. The carabiner 20 is then mounted captive.
Sur la figure 4, l'anse 17 est réalisée en matériau rigide ou semi-rigide, mais sans être élastique. L'anse 17 est indépendante des moyens élastiques, lesquels sont formés par une jupe 32 en matière déformable élastique, par exemple en élastomère ou caoutchouc, ladite jupe étant attachée au corps 12 sous les fentes 13, 14.In Figure 4, the handle 17 is made of rigid or semi-rigid material, but without being elastic. The loop 17 is independent of the elastic means, which are formed by a skirt 32 of elastic deformable material, for example elastomer or rubber, said skirt being attached to the body 12 under the slots 13, 14.
Sur la figure 5, le corps 12 à fentes 13, 14 est relié du côté de la face interne 18 à deux ressorts 27, 28 de compression en liaison avec un support 29. La partie centrale de ce dernier est percé d'un orifice 30 circulaire pour le passage du mousqueton 20. Les deux ressorts 27, 28 sont de préférence identiques.In FIG. 5, the body 12 with slots 13, 14 is connected on the side of the inner face 18 to two compression springs 27, 28 in connection with a support 29. The central part of the latter is pierced with an orifice 30. The two springs 27, 28 are preferably identical.
La figure 6 concerne l'appareil d'assurage 100 décrit dans le document EP- A- 1221327, et comportant un corps 120 métallique ayant un flasque central 31 sur lequel est rapporté un étrier 31a en forme de U de manière à délimiter les deux fentes 13, 14 de part et d'autre du flasque 31. L'anse 17, au lieu d'être rigide comme le flasque métallique 31 , est remplacée par l'anse 17 élastique selon l'invention et illustrée à titre d'exemple à la figure 1 de la présente demande.FIG. 6 relates to the belay device 100 described in document EP-A-1221327, and comprising a metal body 120 having a central flange 31 on which a U-shaped stirrup 31a is attached so as to delimit the two slots 13, 14 on either side of the flange 31. The handle 17, instead of being rigid as the metal flange 31, is replaced by the handle 17 resilient according to the invention and illustrated by way of example in Figure 1 of the present application.
Sur la figure 7, le corps 12 à fentes 13, 14 est équipé d'un ressort 33 hélicoïdal fixé au corps 12, et s'étendant dans la direction de l'élément de retenue fixe en forme d'anse 17. La hauteur de l'anse 17 est supérieure à la longueur axiale du ressort 33 hélicoïdal.In FIG. 7, the slotted body 12, 14 is equipped with a helical spring 33 fixed to the body 12, and extending in the direction of the fixed loop-shaped retaining element 17. The height of the handle 17 is greater than the axial length of the coil spring 33.
Selon la figure 8, le ressort 33 hélicoïdal est prolongé par une spire 34 fermée servant à l'accrochage du mousqueton, et jouant le rôle de l'élément de retenue. According to Figure 8, the coil spring 33 is extended by a closed coil 34 for fastening the carabiner, and acting as the retaining element.
