Un tel descendeur est connu du document FR-2451 752, dans lequel la deuxième poulie est équipée de deux bossages coopérant avec la première poulie pour former un coinceur à deux positions de blocage, lorsque le levier de commande pivotant se trouve alternativement dans deux positions extrêmes. On remarque que la fonction de coincement de chaque bossage s'exerce toujours sur le même brin intermédiaire de la corde, agencé entre les deux poulies. Le débattement du levier de commande entre les deux positions de blocage est de l'ordre d'un quart de cercle, et l'action manuelle de déblocage vers la position intermédiaire du levier de commande nécessite un effort important.Such a descender is known from document FR-2451 752, in which the second pulley is equipped with two bosses cooperating with the first pulley to form a jammer with two locking positions, when the pivoting control lever is alternately in two extreme positions . Note that the wedging function of each boss is always exercised on the same intermediate strand of the rope, arranged between the two pulleys. The movement of the control lever between the two locking positions is of the order of a quarter of a circle, and the manual unlocking action towards the intermediate position of the control lever requires significant effort.

DESCRIPTION DETAILLEE DE L'INVENTION Sur les figures, un descendeur 10 autobloquant à deux positions de blocage, comporte une paire de poulies 12,14, logées dans un intervalle 16 transversal ménagé entre deux flasques 18,20 parallèles. La première poulie 12 est montée fixe au moyen d'une vis 21 sur le premier flasque de base 18, en étant immobilisée en rotation. Le secteur circulaire supérieur de la poulie 12 est doté d'une gorge 22 de guidage de la corde 24. L'autre partie, orientée vers la deuxième poulie 14, est équipée d'une première surface de freinage 26 et d'une deuxième surface de freinage 28. Les deux surfaces 26,28 sont sensiblement rectilignes en faisant entre elles un angle obtu.DETAILED DESCRIPTION OF THE INVENTION In the figures, a self-locking descender 10 with two locking positions, comprises a pair of pulleys 12,14, housed in a transverse gap 16 formed between two parallel flanges 18,20. The first pulley 12 is mounted fixed by means of a screw 21 on the first base flange 18, while being immobilized in rotation. The upper circular sector of the pulley 12 has a groove 22 for guiding the rope 24. The other part, oriented towards the second pulley 14, is equipped with a first braking surface 26 and a second surface braking 28. The two surfaces 26, 28 are substantially rectilinear, forming an obtuse angle between them.
Dans la zone médiane du flasque de base 18 fait saillie un axe 30 fixe, s'étendant parallèlement à la vis 21 de fixation de la première poulie 12. Sur l'axe 30 est monté à rotation limitée un support 32 mobile, séparé du flasque de base 18 par un faible jeu axial, autorisant le pivotement du support 32 à l'intérieur de l'intervalle 16 dans un plan parallèle au flasque de base 18. L'une des extrémités du support 32 mobile est prolongée latéralement par un levier de commande 34, dont l'actionnement manuel pilote le blocage et le déblocage de la corde 24, ainsi que la vitesse de descente. L'autre extrémité du support 32 est pourvue d'un taquet de coincement 36, alors que la deuxième poulie 14 est immobilisée en rotation sur le support 32 entre le levier 34 et le taquet 36.In the central zone of the base flange 18 a fixed axis 30 projects, extending parallel to the screw 21 for fixing the first pulley 12. On the axis 30 is mounted with limited rotation a mobile support 32, separate from the flange base 18 by a small axial clearance, allowing the pivoting of the support 32 inside the gap 16 in a plane parallel to the base flange 18. One of the ends of the movable support 32 is extended laterally by a lever command 34, the manual actuation of which controls the blocking and unblocking of the rope 24, as well as the speed of descent. The other end of the support 32 is provided with a wedging cleat 36, while the second pulley 14 is immobilized in rotation on the support 32 between the lever 34 and the cleat 36.
La deuxième poulie 14 est conformée en came comprenant un secteur circulaire à gorge 38 de guidage de la corde 24, et un bossage 40 destiné à coopérer avec la première surface de freinage 26. Un orifice 42 circulaire traverse la poulie 14 pour autoriser le montage du support 32 mobile sur l'axe 30 fixe du flasque de base 18.The second pulley 14 is shaped as a cam comprising a circular grooved sector 38 for guiding the rope 24, and a boss 40 intended to cooperate with the first braking surface 26. A circular orifice 42 passes through the pulley 14 to allow the mounting of the support 32 movable on the fixed axis 30 of the base flange 18.
L'orifice 42 est excentré par rapport au centre fictif 44 de la gorge 38 de la ù? xième poulie 14, de manière à augmenter le coupl Icrc d'un blocage automatique à la suite d'une chute. L'orifice 42 est situé entre le centre fictif 44 de la gorge 38 et l'arête 46 rectiligne agencée à l'opposé de la gorge 38. Un espace 48 de passage de la corde 24 est ménagé entre la deuxième poulieThe orifice 42 is eccentric relative to the imaginary center 44 of the groove 38 of the ù? 10th pulley 14, so as to increase the coupling Icrc of an automatic blocking following a fall. The orifice 42 is located between the imaginary center 44 of the groove 38 and the straight edge 46 arranged opposite the groove 38. A space 48 for passage of the rope 24 is provided between the second pulley
14 et le taquet de coincement 36.14 and the wedge block 36.
Le deuxième flasque 20 d'obturation de 1'intervalle 16 transversal, est monté à basculement en ciseaux sur l'axe fixe 30 entre une position écartée (fig.l) appropriée à l'engagement selon un S de la corde 24 dans les gorges 22,38 de guidage des deux poulies 12,14, et une position fermée (fig.7) dans laquelle les deux flasques 18,20 sont disposés en regard l'un de l'autre, en empêchant tout échappement de la corde 24 hors de l'intervalle 16. Le premier flasque 18 de base comporte avantageusement un rebord 50 en équerre orienté en direction du deuxième flasque 20.The second flange 20 for closing the transverse interval 16, is mounted to scissor tilt on the fixed axis 30 between a separated position (fig.l) suitable for engagement along an S of the rope 24 in the grooves 22,38 for guiding the two pulleys 12,14, and a closed position (fig. 7) in which the two flanges 18,20 are arranged opposite one another, preventing any escape of the rope 24 out of the interval 16. The first base flange 18 advantageously comprises a square flange 50 oriented in the direction of the second flange 20.
A l'opposé du rebord 50, le premier flasque 18 est doté d'une lumière 52 oblongue de section décroissante vers le bas. Le deuxième flasque 20 comporte également une lumière 54 de même profil, susceptible de venir en alignement en position fermée avec la lumière 52 conjuguée, pour autoriser .le passage d'un mousqueton d'attache, relié au baudrier d'encordement de * l'utilisateur. Un cliquet articulé est associé à la Lumière 52 du deuxième flasque 20 pour faciliter l'introduction du mousqueton.Opposite the rim 50, the first flange 18 is provided with an oblong opening 52 of decreasing section downwards. The second flange 20 also includes a lumen 54 of the same profile, capable of coming into alignment in the closed position with the lumen 52 conjugate, to allow .the passage of a fastening carabiner, connected to the rope harness of * l ' user. An articulated pawl is associated with the light 52 of the second flange 20 to facilitate the introduction of the carabiner.
Le fonctionnement du descendeur 10 autobloquant est le suivant :The functioning of the self-locking descender 10 is as follows:
Après basculement du deuxième flasque 20 vers la position écartée (fig.l), l'utilisateur enroule la corde 24 autour de la gorge 38 de la deuxième poulie 14, suivi du passage dans l'espace intermédiaire délimité par l'arête 46 et la première surface de freinage 26. La corde 24 passe ensuite dans la gorge 22 de la première poulie 12, puis dans l'espace 48 adjacent entre le taquet de coincement 36 et l'arête 46. La refermeture du deuxième flasque 20 emprisonne la corde 24 dans l'intervalle 16, et tout écartement accidentel des flasques 12,14 est exclu par la présence du mousqueton dans les lumières 52,54. La section décroissante des lumières 52,54 permet un positionnement et un centrage corrects du mousqueton indépendamment de sa dimension.After tilting of the second flange 20 towards the separated position (fig.l), the user wraps the cord 24 around the groove 38 of the second pulley 14, followed by passage through the intermediate space delimited by the edge 46 and the first braking surface 26. The rope 24 then passes through the groove 22 of the first pulley 12, then into the space 48 adjacent between the wedging cleat 36 and the edge 46. The reclosing of the second flange 20 traps the rope 24 in the interval 16, and any accidental separation of the flanges 12,14 is excluded by the presence of the carabiner in the slots 52,54. The decreasing section of the lights 52, 54 allows correct positioning and centering of the carabiner regardless of its size.
La figure 2 montre le descendeur 10 en position débloquée, correspondant à la position intermédiaire de la poig>.éβ .de commando 34, autor-i^ant le mouvement de descente de l'utilisateur le long de la corde 24 verticale. La vitesse de descente est contrôlée par la friction de la corde 24 dans les deux gorges 22,38 des poulies 12,14. La venue de la poignée 34 dans la position intermédiaire résulte d'une action volontaire exercée manuellement par l'utilisateur dans le sens de la flèche FI. Il en résulte un pivotement prédéterminé du support 32 autour de 1'axe 30 et dans le sens inverse des aiguilles d'une montre, de manière à neutraliser la réaction du bossage 40 et du taquet de coincement 36 sur la corde 24.Figure 2 shows the descender 10 in the unlocked position, corresponding to the intermediate position of the poig> .é β .de commando 34, authorizing the downward movement of the user along the vertical rope 24. The speed of descent is controlled by the friction of the rope 24 in the two grooves 22,38 of the pulleys 12,14. The coming of the handle 34 in the intermediate position results from a voluntary action exerted manually by the user in the direction of the arrow FI. This results in a predetermined pivoting of the support 32 around the axis 30 and in an anti-clockwise direction, so as to neutralize the reaction of the boss 40 and the jamming cleat 36 on the rope 24.
En cas de relâchement de la poignée de commande 34, notamment à la suite d'une chute non contrôlée, les forces de friction engendrent une tension sur la corde 24 (voir flèche F2, fig.3) qui sollicite le support 32 mobile dans le sens des aiguilles d'une montre. Le bossage 40 de la deuxième poulie 14 coince la corde 24 contre la première surface de freinage 26 de la première poulie 12, et bloque automatiquement le mouvement de descente. L'utilisateur reste alors suspendu en toute sécurité à la corde 24, et la poignée de commande 34 occupe une première position relevée de blocage. Dans cette position, le couple de serrage de la corde est optimum, grâce à l'excentricité de la deuxième poulie 14. Le taquet de coincement 36 est inactif, en étant écarté au maximum de la deuxième surface de freinage 28.In the event of release of the control handle 34, in particular following an uncontrolled fall, the friction forces generate a tension on the rope 24 (see arrow F2, fig. 3) which urges the support 32 movable in the clockwise. The boss 40 of the second pulley 14 wedges the rope 24 against the first braking surface 26 of the first pulley 12, and automatically blocks the downward movement. The user then remains safely suspended from the rope 24, and the control handle 34 occupies a first raised blocking position. In this position, the tightening torque of the rope is optimum, thanks to the eccentricity of the second pulley 14. The wedging cleat 36 is inactive, being separated as far as possible from the second braking surface 28.
A partir de cette première position de blocage, le déblocage s'opère normalement par abaissement manuel de la poignée 34 selon la flèche FI, vers la position intermédiaire de la figure 2.From this first locking position, the unlocking takes place normally by manual lowering of the handle 34 according to the arrow FI, towards the intermediate position of FIG. 2.
Cette action de déblocage est facilitée par le positionnement en saillie du levier de commande 34, lequel s'étend sensiblement à angle droit par rapport au flasque de base 18.This unlocking action is facilitated by the projecting positioning of the control lever 34, which extends substantially at right angles to the base flange 18.
Un déplacement poursuivi au-delà de la position intermédiaire, amène le support 32 et la poignée de commande 34 vers une deuxième position abaissée de blocage (figure 4), dans laquelle le taquet de coincement 36 presse la corde .24 contre la deuxième surface de freinage 28 de la première poulie 12. La deuxième poulie 14 n'exerce aucun effet de blocage sur la corde 24, étant donné que l'arête 46 est sensiblement parallèle à la première surface de freinage 26. Le déblocage de la corde 24 se produit automatiquement par relèvement dé la poignée de commande 34 vers la position intermédiaire.Continued movement beyond the intermediate position brings the support 32 and the control handle 34 to a second lowered locking position (FIG. 4), in which the wedging cleat 36 presses the rope .24 against the second surface of braking 28 of the first pulley 12. The second pulley 14 has no locking effect on the rope 24, since the edge 46 is substantially parallel to the first braking surface 26. The rope 24 is released. automatically by raising the control handle 34 to the intermediate position.
La figure 5 montre 'état du descendeur lu hors-service, notamment lors du transport. La forme et l'excentricité de la deuxième poulie 14 autorisent en l'absence de corde 24, un libre pivotement du levier de commande 34 au-delà de la première position, sans que le bossage 40 ne touche la première surface de freinage 26. La poignée 34 est alors sensiblement parallèle aux flasques 18,20, et ne se trouve plus en saillie. Le transport du descendeur 10 s'effectue alors sans gêne pour l'utilisateur.Figure 5 shows the state of the descender read out of service, especially during transport. The shape and the eccentricity of the second pulley 14 allow, in the absence of rope 24, free pivoting of the control lever 34 beyond the first position, without the boss 40 touching the first braking surface 26. The handle 34 is then substantially parallel to the flanges 18,20, and is no longer projecting. The transport of the descender 10 is then carried out without discomfort for the user.
Selon une variante, l'orifice 42 de la deuxième poulie 14 est agencé coaxialement sur le centre fictif 44.According to a variant, the orifice 42 of the second pulley 14 is arranged coaxially on the imaginary center 44.
L'invention s'étend également à un descendeur pour corde double de rappel, dans lequel chaque poulie 12,14 comporte deux gorges juxtaposées de guidage de la corde 24. The invention also extends to a descender for a double return rope, in which each pulley 12, 14 has two juxtaposed grooves for guiding the rope 24.
