    Description d'un mode de réalisation préférentiel.Description of a preferred embodiment.

    En référence aux figures 1 à 4, un dispositif assureur descendeur 10 pour l'escalade ou l'alpinisme, comporte un corps 12 métallique composé d'un flasque 14 central sur lequel est rapporté un étrier 16 en forme de U, de manière à définir deux fentes 18, 20 adjacentes pour le passage de la corde.With reference to FIGS. 1 to 4, a descending belay device 10 for climbing or mountaineering, comprises a metallic body 12 composed of a central flange 14 to which is attached a U-shaped bracket 16, so as to define two adjacent slots 18, 20 for the passage of the rope.

    L'âme 22 de l'étrier 16 est dotée dans la zone médiane de deux saignées de centrage 24, 26, alignées dans le plan du flasque 14 et ayant chacune une épaisseur légèrement supérieure à celle du flasque 14. Les extrémités des deux ailes 28, 30 symétriques de l'étrier 16 sont pourvues d'orifices 32 circulaires destinées à recevoir un organe d'assemblage 34, par exemple un rivet, lequel traverse coaxialement deux douilles 36, 38 et le flasque 14 dans la direction transversale. Chaque douille 36, 38 constitue un moyen de butée fixe, qui ferme la fente 18, 20 correspondante à l'opposé de l'âme 22 et dans la partie rétrécie de l'étrier 16. Un bossage 39 est ménagé sur chaque douille 36, 38 pour améliorer le blocage de la corde en cas de chute. The core 22 of the stirrup 16 is provided in the median zone with two grooves of centering 24, 26, aligned in the plane of the flange 14 and each having a thickness slightly greater than that of the flange 14. The ends of the two symmetrical wings 28, 30 of the stirrup 16 are provided with orifices 32 circulars intended to receive an assembly member 34, for example a rivet, which coaxially passes through two sockets 36, 38 and the flange 14 in the transverse direction. Each socket 36, 38 constitutes a stop means fixed, which closes the corresponding slot 18, 20 opposite the core 22 and in the narrowed part of the stirrup 16. A boss 39 is provided on each bushing 36, 38 to improve the blocking of the rope in the event of a fall.

    Le flasque 14 s'étend dans le plan vertical médian, et comporte une première ouverture 40 en forme d'anse de retenue, et une deuxième ouverture 42 pour l'accrochage d'un mousqueton dans le cas de l'assurage du deuxième de cordée. Un trou 44 additionnel de forme rectangulaire est également prévu dans le flasque 14 pour autoriser le passage de l'organe d'assemblage 34, et l'insertion de deux ergots 46 faisant saillie de chaque douille 36, 38 dans la direction transversale. La partie centrale du trou 44 est circulaire, et présente un diamètre légèrement supérieur à celui du rivet.The flange 14 extends in the median vertical plane, and comprises a first opening 40 in the form of a retaining loop, and a second opening 42 for the hooking of a carabiner in the case of the belaying of the second roped. An additional hole 44 of rectangular shape is also provided. in the flange 14 to allow the passage of the assembly member 34, and the insertion of two lugs 46 projecting from each socket 36, 38 in the transverse direction. The central part of hole 44 is circular, and has a diameter slightly greater than that of the rivet.

    Lors du montage de l'étrier 16, les deux saignées de centrage 24, 26 de l'âme 22 s'engagent dans la partie centrale du flasque 14. Les deux douilles 36, 38 fixes sont bloquées en rotation suite à la pénétration des ergots 46 dans le trou 44 rectangulaire du flasque 14, et les bossages 39 sont orientés vers l'intérieur de l'étrier 16. L'âme 22 forme un plan incliné agencé entre la deuxième ouverture 42 et les deux douilles 36, 38 fixes.When mounting the bracket 16, the two centering grooves 24, 26 of the core 22 engage in the central part of the flange 14. The two sockets 36, 38 fixed are locked in rotation following the penetration of the lugs 46 in the rectangular hole 44 of the flange 14, and the bosses 39 are oriented towards the inside of the stirrup 16. The core 22 forms an inclined plane arranged between the second opening 42 and the two fixed sockets 36, 38.

    Le dispositif assureur descendeur 10 selon les figures 1 à 4 est réalisé par découpage pliage d'une tôle en aluminium ou en acier inoxydable, mais il est clair qu'il pourrait être forgé.The belay device 10 according to FIGS. 1 to 4 is produced by cutting folding of an aluminum or stainless steel sheet, but it is clear that it could be forged.

    Les différents modes d'utilisation du dispositif assureur descendeur 10 selon l'invention sont les suivants :The different modes of use of the descender insurer device 10 according to the invention are as follows:

    L'appareil peut être utilisé en corde simple ou en corde double. Dans le cas d'une corde simple (non représentée), une seule fente 18 ou 20 est traversée longitudinalement par une boucle de la corde dans un plan décalé parallèle au flasque 14. Dans le cas d'une corde double, les deux fentes 18, 20 sont utilisées, avec deux boucles de corde s'étendant parallèlement de part et d'autre du flasque 14.The device can be used in single rope or double rope. In the case a single rope (not shown), a single slot 18 or 20 is crossed longitudinally by a loop of the rope in a parallel offset plane to the flange 14. In the case of a double cord, the two slots 18, 20 are used, with two loops of rope extending parallel to each other and other side of flange 14.

    Les figures suivantes illustrent l'installation du dispositif assureur descendeur 10 avec le deuxième cas en corde double.The following figures illustrate the installation of the belay device descender 10 with the second case in double rope.

    Assurage du premier de cordée ( figures 5 et 6).Belaying the first rope (Figures 5 and 6).

    Le premier de cordée grimpe, et est assuré par le deuxième de cordée qui se trouve en-dessous. Deux boucles de la corde double 48 sont logées dans les fentes 18, 20 du dispositif assureur descendeur 10, et un premier mousqueton 50 traverse les deux boucles et l'anse 40, en étant attaché à l'anneau 52 du baudrier 54 appartenant au second de cordée. L'une des mains 56 du deuxième de cordée tient les brins supérieurs de la corde reliés au premier de cordée, tandis que l'autre main 58 entoure les brins inférieurs. La deuxième ouverture 42 du flasque 14 n'est pas utilisée dans ce mode d'assurage.The first of the rope climbs, and is provided by the second of the rope which is found below. Two loops of the double rope 48 are housed in the slots 18, 20 of the descending belay device 10, and a first carabiner 50 crosses the two loops and the loop 40, being attached to the ring 52 of the harness 54 belonging to the second of rope. One of hands 56 of the second of the rope hold the upper strands of the rope connected at the first of the rope, while the other hand 58 surrounds the lower strands. The second opening 42 of the flange 14 is not used in this mode belay.

    Lors de la progression normale du premier de cordée, il suffit que la main 58 du deuxième de cordée donne du mou dans le sens de la flèche F1 pour autoriser le libre coulissement de la corde 48 dans l'appareil.During the normal progression of the first rope, it suffices that the hand 58 of the second of the rope gives slack in the direction of the arrow F1 for authorize the free sliding of the rope 48 in the device.

    Pour bloquer le premier de cordée, notamment en cas de chute, le deuxième de cordée serre les brins inférieurs avec sa main 58 en sollicitant la corde 48 dans le sens de la flèche F2. Il en résulte un coincement des boucles de corde sur les bossages 39 des douilles 36, 38, et un blocage des brins supérieurs de la corde 48. To block the first rope, especially in the event of a fall, the second of rope tightens the lower strands with his hand 58 while straining the rope 48 in the direction of arrow F2. This results in jamming of the loops cord on the bosses 39 of the sockets 36, 38, and a blockage of the strands rope superiors 48.

    Assurage du deuxième de cordée ( figures 7 et 8).Belaying the second rope (Figures 7 and 8).

    Le deuxième de cordée grimpe, et est assuré par le premier de cordée qui se trouve au-dessus, notamment à un relais. La corde 48 est attachée au baudrier du deuxième de cordée, et le premier mousqueton 50 traverse l'anse 40 et les boucles de corde de l'appareil 10 du premier cordée, mais sans être attaché au baudrier de ce dernier. L'appareil 10 est relié à des moyens d'amarrage 60 fixes par l'intermédiaire d'un deuxième mousqueton 62 passant à travers la deuxième ouverture 42 du flasque 14.The second of the rope climbs, and is provided by the first of the rope which is found above, including a relay. The rope 48 is attached to the harness of the second rope, and the first carabiner 50 crosses the handle 40 and the rope loops of the apparatus 10 of the first rope, but without being attached to the harness of the latter. The apparatus 10 is connected to means 60 fixed mooring via a second carabiner 62 passing through the second opening 42 of the flange 14.

    Lors de la progression normale du deuxième de cordée, la corde peut coulisser librement dans l'appareil 10, et les mains 56, 58 du premier de cordée accompagnent le mouvement de la corde 48 (flèches F3 et F4), de manière à rattraper au fur et à mesure le mou se formant sur le tronçon entre le deuxième de cordée et l'appareil 10.During normal progression of the second rope, the rope may slide freely in the apparatus 10, and the hands 56, 58 of the first of cordée accompany the movement of cord 48 (arrows F3 and F4), so as to catch up progressively the slack forming on the section between the second of the team and the apparatus 10.

    En cas de chute du deuxième de cordée, le blocage instantané de l'appareil 10 coinceur est automatique, entraínant l'arrêt de la chute. Les chocs sont absorbés intégralement par l'appareil 10 et les moyens d'amarrage 60 fixes.In the event of a fall in the second rope, the instantaneous blocking of the device 10 jammer is automatic, causing the fall to stop. The shocks are fully absorbed by the apparatus 10 and the fixed mooring means 60.

    Descendeur (figure 9).Descender (Figure 9).

    On utilise l'appareil 10 comme dans le cas des figures 5 et 6, mais dans le sens de la descente. Il se comporte alors comme un descendeur avec le premier mousqueton 50 attaché au baudrier 54. Pour freiner ou arrêter le mouvement de descente, il suffit de tirer plus ou moins énergiquement sur la corde avec la main 56 comme on le fait d'une manière classique avec des descendeurs simples. Un élément de sécurité rappel 64 additionnel peut être adapté sur les brins inférieurs, et contrôlé par l'autre main 58.The apparatus 10 is used as in the case of FIGS. 5 and 6, but in the direction of descent. He then behaves like a descender with the first carabiner 50 attached to the harness 54. To brake or stop the downward movement, just pull more or less vigorously on the rope with the hand 56 as we do in a classic way with single descenders. An additional reminder security element 64 can be adapted on the lower strands, and controlled by the other hand 58.
