Description
L'invention est relative à un dispositif bloqueur de remontée sur corde double, composé d'un premier bloqueur et d'un deuxième bloqueur assemblés l'un à l'autre par des moyens de fixation, chaque bloqueur comprenant :
- un flasque métallique découpé à la partie inférieure par une lumière en formant une poignée de préhension du côté extérieur,
- une goulotte agencée à la partie supérieure du flasque pour le passage de la corde,
- et un taquet pivotant doté d'une surface de blocage de la corde dans le fond de ladite goulotte.
- a metal flange cut at the bottom by a light forming a handle on the outside,
- a chute arranged at the upper part of the flange for the passage of the rope,
- and a pivoting latch with a locking surface of the rope in the bottom of said chute.
Les bloqueurs pour corde double utilisent généralement un premier bloqueur à poignée pour main droite et un deuxième bloqueur à poignée pour main gauche, lesquels sont montés dos à dos sans décalage de manière à superposer les deux poignées. Les deux goulottes sont disposées côte-à-côte avec les taquets de blocage correspondants, et l'assemblage final de l'appareil s'effectue par rivetage des deux poignées.Double rope clamps typically use a first right hand grip blocker and a second left hand grip locker, which are mounted back-to-back without offset to overlap both handles. The two chutes are arranged side by side with the corresponding locking tabs, and the final assembly of the apparatus is effected by riveting the two handles.
Dans un autre appareil connu, les poignées sont écartées l'une de l'autre sans être superposées pour permettre une meilleure préhension par les deux mains. Les deux goulottes restent néanmoins disposées côte-à-côte comme dans le premier cas précité.In another known device, the handles are spaced apart from each other without being superimposed to allow better grip with both hands. The two chutes remain nevertheless arranged side by side as in the first case mentioned above.
Dans tous ces appareils connus, les deux bloqueurs possèdent des flasques de structures différentes, qui nécessitent plusieurs types d'outillages pour le découpage et le pliage des flasques droit et gauche des deux bloqueurs.In all these known devices, the two blockers have flanges of different structures, which require several types of tools for cutting and folding the left and right flanges of the two blockers.
L'objet de l'invention consiste à réaliser un dispositif bloqueur facile à utiliser et à tenir lors de la remontée le long d'une corde double, et réalisé avec des pièces standards nécessitant le même outillage pour la fabrication des deux bloqueurs.The object of the invention is to provide a blocking device easy to use and hold during the ascent along a double rope, and made with standard parts requiring the same tools for the manufacture of two blockers.
Le dispositif selon l'invention est caractérisé en ce que les flasques des deux bloqueurs sont identiques et sont inversés par pivotement de 180° l'un par rapport à l'autre suivant un axe vertical s'étendant parallèlement aux deux goulottes, et que les deux poignées de préhension sont symétriques par rapport à l'axe vertical de manière à pouvoir être tenues simultanément par la main droite et la main gauche de l'utilisateur.The device according to the invention is characterized in that the flanges of the two blockers are identical and are reversed by pivoting 180 ° relative to each other along a vertical axis extending parallel to the two channels, and that the two handles are symmetrical about the vertical axis so that they can be held simultaneously by the right hand and the left hand of the user.
Il en résulte une tenue équilibrée du dispositif bloqueur pour corde double. Les deux flasques de structures identiques sont réalisés chacun avec le même outillage dans le cas d'une opération de découpage et de pliage, ou le même moule dans le cas d'une fabrication en fonderie.This results in a balanced hold of the locking device for double rope. The two flanges of identical structures are each made with the same tooling in the case of a cutting and folding operation, or the same mold in the case of a foundry manufacture.
Les deux flasques sont superposés à la base, et comportent une paire d'orifices coaxiaux constituant un trou d'accrochage unique pour le passage d'un mousqueton.The two flanges are superimposed on the base, and comprise a pair of coaxial orifices constituting a single attachment hole for the passage of a carabiner.
Selon un premier mode de réalisation, les poignées des flasques sont réunies du côté interne à deux branches superposées s'étendant verticalement dans le prolongement des goulottes, et comportant des trous coaxiaux pour le passage des moyens de fixation.According to a first embodiment, the handles of the flanges are joined on the inner side with two superimposed branches extending vertically in the extension of the troughs, and having coaxial holes for the passage of the fastening means.
Selon un deuxième mode de réalisation, les bloqueurs sont assemblés en forme de coeur, sans branches superposées du côté interne.According to a second embodiment, the blockers are assembled in the form of a heart, without superposed branches on the internal side.
Les flasques identiques du dispositif bloqueur peuvent être réalisés par découpage pliage, par usinage d'un profilé métallique, ou par fonderie.The identical flanges of the blocking device can be made by cutting bending, by machining a metal section, or by foundry.

La partie supérieure de chaque bloqueur 11 A, 11B est pliée en U pour constituer une goulotte 16A, 16B verticale de logement de la corde C1, C2, et comporte en plus un taquet 17A, 17B articulé sur un axe de pivotement 18A, 18B transversal. Chaque taquet 17A, 17B est doté d'une surface de blocage en forme de came, équipée d'une pluralité de picots du type décrit dans le document
A l'opposé de la poignée 15A, 15B, chaque lumière 14A, 14B du flasque 13A, 13B est délimitée par une branche 19A, 19B sensiblement rectiligne s'étendant verticalement dans le prolongement et sous la goulotte 16A, 16B correspondante.Opposite the
La base de chaque branche 19A, 19B des flasques 13A, 13B est pourvue d'un orifice 20A, 20B circulaire pour le passage d'un mousqueton. La partie intermédiaire des branches 19A, 19B comporte en plus des trous 21 de diamètres inférieurs à ceux des orifices 20A, 20B. Les trous 21 seront utilisés pour la mise en place des moyens de fixation 12.The base of each
L'assemblage des deux bloqueurs 11 A, 11B s'effectue de la manière suivante :
- Les
13A, 13B des deuxflasques 11 A, 11B sont identiques, et sont inversés l'un par rapport à l'autre suite à un mouvement de pivotement vertical de 180°, en étant accolés par leursbloqueurs 19A, 19B internes et leursbranches 16A, 16B. Lesgoulottes 19A, 19B rectilignes sont ainsi superposées, et lesbranches 20A, 20B sont coaxiaux et alignés dans la direction transversale.orifices
- The
13A, 13B of the twoflanges 11A, 11B are identical, and are inverted relative to each other following a vertical pivoting movement of 180 °, being contiguous by theirblockers 19A, 19B and theirinternal branches 16A, 16B. Thechutes 19A, 19B rectilinear are thus superimposed, and thebranches 20A, 20B are coaxial and aligned in the transverse direction.orifices
Les trous 21 dans les branches 19A, 19B sont également alignés, ce qui permet le passage des moyens de fixation 12, constitués par des rivets ou tout autre système d'assemblage. Deux rivets dans les branches 19A, 19B superposées sont suffisants pour obtenir la résistance mécanique souhaitée du dispositif bloqueur 10.The

Lors de la remontée le long d'une corde double C1,C2, l'utilisateur attache d'abord le dispositif bloqueur 10 au baudrier par l'intermédiaire d'un mousqueton (non représenté) traversant les orifices 20A, 20B. Il passe ensuite la corde double C1, C2 dans les goulottes 16A, 16B, puis monte le long de la corde C1, C2 en tenant les deux poignées 15A, 15B par la main droite et la main gauche.During the ascent along a double rope C1, C2, the user first attaches the
