Abstract
Description
Mousqueton de sécurité.Safety carabiner.
L'invention se rapporte aux mousquetons de sécurité, dont il est notamment fait usage avec les harnais de sécurité, pour la protection des personnes exerçant des activités risquées, ou dans des systèmes d'attache ou de manutention divers.The invention relates to safety carabiners, which are used in particular with safety harnesses, for the protection of persons carrying out risky activities, or in various attachment or handling systems.
On connaît déjà une réalisation de mousqueton à linguet articulé ouvrant dans laquelle la sécurité est assurée à l'aide d'un manchon de verrouillage du linguet vissable en position de fermeture du mousqueton. Le fait de devoir visser ou dévisser manuellement le manchon pour, soit la sécurité de fermeture,soit l'ouverture du mousqueton, constitue une sujétion que l'utilisateur a tendance à négliger au détriment de la sécurité.There is already known an embodiment of a carabiner with an articulated latch opening in which security is ensured by means of a sleeve for locking the latch screwable in the closed position of the carabiner. The fact of having to manually screw or unscrew the sleeve for either closing security or opening of the carabiner constitutes a constraint that the user tends to neglect at the expense of security.
La présente invention a pour objet une réalisation de mousqueton perfectionnée quant à la facilité d'emploi et à la sécurité qu'elle apporte automatiquement.The present invention relates to an improved carabiner in terms of the ease of use and the security which it automatically provides.
Essentiellement, à cet effet, le mousqueton de sécurité selon l'invention, à linguet articulé ouvrant et manchon de verrouillage en position de fermeture du mousqueton, est caractérisé en ce que ledit manchon est monté coulissant sur les parties du linguet et du mousqueton adjacentes à leur axe d'articulation et rappelé par ressort en une position de chevauchement de ces parties correspondant au verrouillage du mousqueton, de sorte que ce dernier est déverrouillable par déplacement coulissant du manchon sur l'une desdites parties au delà dudit axe d'articulation et automatiquement reverrouillable par relâchement du manchon.Essentially, for this purpose, the safety carabiner according to the invention, with an open articulated latch and locking sleeve in the closed position of the carabiner, is characterized in that said sleeve is mounted to slide on the parts of the latch and of the carabiner adjacent to their axis of articulation and returned by spring in an overlapping position of these parts corresponding to the locking of the carabiner, so that the latter is unlockable by sliding movement of the sleeve on one of said parts beyond said axis of articulation and automatically relockable by releasing the sleeve.
De préférence et pour la meilleure facilité d'emploi possible, le manchon est déplaçable à coulissement sur le linguet pour le déverrouillage, de sorte que par une seule action de pousse du manchon à l'aide du pouce on obtient à la fois le déverrouillage et l'ouverture voulue du linguet en tenant le mousqueton en main.Preferably and for the best possible ease of use, the sleeve can be moved to slide on the latch for unlocking, so that by a single pushing action of the sleeve with the thumb, both unlocking and the desired opening of the latch while holding the carabiner in hand.
Une forme de réalisation d'un tel mousqueton de sécurité est d'ailleurs ci-après décrité à titre d'exemple et en référence au dessin annexé, dans lequel - la figure 1 est une vue du mousqueton en position de fermeture, avec coupe axiale du manchon de verrouillage ; - la figure 2 est une vue du mousqueton en position d'ouverture, avec coupe axiale du manchon en position de déverrouillage
Le mousqueton représenté comprend un crochet 1 formant une boucle ouverte à l'une des extrémités de laquelle est articulé, par l'intermédiaire d'un axe 2, un linguet 3 formant organe de fermeture de la boucle et coopérant ici avec elle par un interengagement de dentures d'extrémité 4 et 5.An embodiment of such a safety carabiner is moreover described below by way of example and with reference to the attached drawing, in which - Figure 1 is a view of the carabiner in the closed position, with axial section the locking sleeve; - Figure 2 is a view of the carabiner in the open position, with axial section of the sleeve in the unlocked position
The carabiner shown comprises a hook 1 forming an open loop at one end of which is articulated, via a pin 2, a latch 3 forming a member for closing the loop and cooperating here with it by an interengagement end teeth 4 and 5.
Unmanchon 6 de verrouillage en position de fermeture du linguet est prévu pour venir chevaucher dans cette fonction les parties du crochet 1 et du linguet 3 adjacentes à leur axe d'articulation, dans la position représentée à la figure 1. A sleeve 6 for locking in the closed position of the latch is provided to overlap in this function the parts of the hook 1 and of the latch 3 adjacent to their articulation axis, in the position shown in FIG. 1.
A cet effet le manchon 6 est soumis à l'action d'un ressort de rappel 7 interposé entre lui et le linguet, ce ressprt ayant ici une spire d'extrémité engagée serrée dans une gorge 8 du linguet tandis que son autre spire d'extrémité prend appui sur un épaulement interne 9 du manchon 6, dont le bord d'extrémité 10 rient alors en butée contre la spire engagée dans la gorge 8.To this end, the sleeve 6 is subjected to the action of a return spring 7 interposed between it and the latch, this spring having here an engaged end turn clamped in a groove 8 of the latch while its other turn end is supported on an internal shoulder 9 of the sleeve 6, the end edge 10 of which then laugh in abutment against the turn engaged in the groove 8.
Pour être de manoeuvre plus sore, le manchon 6 est en outre ici monté coulissant sans rotation relative par rapport au linguet, par engagement avec un plat Il ménagé sur ce dernier, du bord d'extrémité 10 du manchon qui est déforme en correspondance du plat 11.To be more manoeuvrable, the sleeve 6 is also here mounted to slide without relative rotation relative to the latch, by engagement with a dish II formed on the latter, from the end edge 10 of the sleeve which is deformed in correspondence with the dish 11.
De plus, le manchon 6 est pourvu d'une collerette 12 d'appui du pouce, destinée à éviter ou limiter un glissement éventuel du pouce lorsqu'on déplace le manchon en position de déverrouillage et d'ouverture du linguet 3 comme représenté à la figure 2, en tenant le crochet dans la main. Le risque de glissement est également prévenu ici en moletant la partie du manchon 3 destinée à recevoir l'appui du pouce.In addition, the sleeve 6 is provided with a collar 12 for supporting the thumb, intended to avoid or limit possible sliding of the thumb when the sleeve is moved to the unlocking and opening position of the latch 3 as shown in FIG. Figure 2, holding the hook in your hand. The risk of slipping is also prevented here by knurling the part of the sleeve 3 intended to receive the support of the thumb.
On notera en effet que l'ouverture du mousqueton résulte automatiquement d'une simple action d'appui du pouce sur le manchon 6, le long du linguet 3, laquelle provoque d'abord sont déverrouillage lorsque le manchon ne chevauche plus que le linguet, en même temps qutil passe alors en position d'ouverture (figure 2).It will in fact be noted that the opening of the carabiner automatically results from a simple pressing action of the thumb on the sleeve 6, along the latch 3, which first causes its unlocking when the sleeve no longer overlaps the latch, at the same time as it then goes into the open position (Figure 2).
La fermeture verrouillée du mousqueton résulte du simple relâchement de la poussée exercée sur le manchon 6, car ce dernier, sous l'action de son ressort de rappel 7, vient automatiquement se réemboîter sur la partie du crochet adjacente à l'axe d'articulation 2 en rappelant ainsi le linguet 3 en position de fermeture et en le verrouillant par ce réemboetement. On notera que l'action du ressort de rappel 7 peut permettre de se dispenser de l'emploi usuel d'un ressort interne de réalignement du linguet et de ladite partie adjacente du crochet. Un tel ressort de réalignement peut néanmoins être maintenu par souci supplémentaire de sécurité.The locked closure of the carabiner results from the simple release of the thrust exerted on the sleeve 6, because the latter, under the action of its return spring 7, automatically re-engages on the part of the hook adjacent to the axis of articulation 2, thus recalling the latch 3 in the closed position and locking it by this repositioning. It will be noted that the action of the return spring 7 can make it possible to dispense with the usual use of an internal spring for realigning the latch and said adjacent part of the hook. Such a realignment spring can nevertheless be maintained for additional security concerns.
Bien entendu diverses variantes de réalisation peuvent aussi ereimaginées sans pour autant sortir du domaine de l'invention. Of course, various variant embodiments can also be imagined without departing from the scope of the invention.
