Abstract
The invention relates to a closing system with momentary locking which allows snap hooks to be used during climbing without risk of untimely opening. The system consists of a snap hook whose body includes, close to the hook (6), a stop (9) for the pin (5) of the articulated finger (2) and, at the other end, a recess (11) which is larger than the axle of the finger (3) thus allowing said finger to move longitudinally.
Description
SYSTEME DE FERMETURE AVEC BLOCAGE MOMENTANE POUR MOUSQUE¬ TON D'ALPINISME ET SPELEOLOGIE. CLOSING SYSTEM WITH MOMENTARY LOCKING FOR MOUNTAINEERING AND SPELEOLOGY.
La présente invention concerne le domaine de l'es- calade et de la spéléologie et plus particulièrement les mousquetons utilisés pour la pratique de ces deux activi¬ tés.The present invention relates to the field of climbing and speleology and more particularly to the carabiners used for the practice of these two activities.
D'une manière traditionnelle, les mousquetons ac- tuels sont constitués d'un corps en alliage léger en forme de C et d'un doigt articulé sur une extrémité du corps et maintenu en position de fermeture par un ressort interne ; l'utilisateur exerce une pression sur le doigt, contre l'effet du ressort, pour mettre la corde d'attache dans le mousqueton ou pour l'enlever de ce dernier.Traditionally, the current carabiners consist of a light alloy C-shaped body and a finger articulated on one end of the body and held in the closed position by an internal spring; the user exerts pressure on the finger, against the effect of the spring, to put the tether in the carabiner or to remove it.
La résistance à la rupture des mousquetons est don¬ née par des normes internationales qui l'ont fixée à 2000 ou 2200 DAN au minimum lorsque le doigt est fermé, et de 600 à 900 DAN lorsque le doigt est ouvert. On voit donc toute l'importance du fait que le mousqueton soit tou¬ jours fermé au cours de la pratique de l'escalade ou de la spéléologie ; or, au cours de ces activités, on a pu déterminer que dans trois cas au moins le doigt pouvait s'ouvrir, à savoir lorsque le mousqueton contenant la corde frappe la paroi au cours d'une chute du grimpeur, lorsque la corde formant boucle autour du doigt vient appuyer sur ce dernier, et lors des phénomènes vibratoi¬ res engendrés par le frottement de la corde dans le mous- queton au cours de certaines chutes.The breaking strength of carabiners is given by international standards which have set it at 2000 or 2200 DAN at least when the finger is closed, and from 600 to 900 DAN when the finger is open. We therefore see the importance of the fact that the carabiner is always closed during the practice of climbing or speleology; however, during these activities, it was determined that in at least three cases the finger could open, namely when the carabiner containing the rope struck the wall during a fall of the climber, when the rope forming a loop around the finger comes to press on the latter, and during vibratoi¬ res phenomena generated by the friction of the rope in the snap hook during certain falls.
On comprend donc alors que dans ces trois cas, la sécurité de l'utilisateur n'est plus assurée puisque 1'ouverture totalement involontaire du doigt ramènera la résistance du mousqueton à une résistance trop faible (600 à 900 DAN) pour résister à la plupart des chutes importantes.
La présente invention vise à pallier ces inconvé¬ nients d'une manière fiable et efficace et concerne, d'une manière générale, un système permettant un blocage volontaire et momentané du doigt du mousqueton dans les trois cas évoqués précédemment.We therefore understand that in these three cases, the safety of the user is no longer ensured since the totally involuntary opening of the finger will reduce the carabiner's resistance to too low a resistance (600 to 900 DAN) to withstand most significant falls. The present invention aims to overcome these drawbacks in a reliable and efficient manner and relates, in general, to a system allowing voluntary and temporary blocking of the carabiner's finger in the three cases mentioned above.
Certes il existe, comme cela ressort notamment des FR-A-2 461 146, US-A-3 367 001 et FR-A-2 108 846, des mousquetons dits "de sécurité" qui permettent d'éviter le risque d'une ouverture intempestive, même si un effort extérieur est exercé sur le doigt. Les solutions décrites dans ces documents qui font appel à des moyens tels que virole manipulée par vissage ou translation permettent un blocage total du doigt en position- verrouillée, rendant l'ouverture du mousqueton impossible. Ces mousquetons ne sont cependant pas utilisables comme mousquetons de pro¬ gression car, outre leur poids important du à la virole supplémentaire, la manipulation nécessite l'usage des deux mains, ce qui est pratiquement impossible pour le grimpeur en activité, surtout lorsqu'il réalise un pas¬ sage d'escalade difficile étant donné que dans un tel cas, il est bien connu, compte tenu du principe même de l'escalade, qu'il est nécessaire d'avoir toujours trois points d'appui (les deux pieds et une main) et qu'en conséquence, toutes les manoeuvres doivent être faites d'une seule main.Certainly there are, as is apparent in particular from FR-A-2 461 146, US-A-3 367 001 and FR-A-2 108 846, so-called "safety" carabiners which make it possible to avoid the risk of inadvertent opening, even if an external force is exerted on the finger. The solutions described in these documents which use means such as a shell manipulated by screwing or translation allow total locking of the finger in the locked position, making it impossible to open the carabiner. These carabiners are not, however, usable as pro¬ gression carabiners because, in addition to their significant weight due to the additional ferrule, handling requires the use of two hands, which is practically impossible for the active climber, especially when performs a difficult climbing pass given that in such a case, it is well known, taking into account the very principle of climbing, that it is necessary to always have three support points (both feet and one hand) and therefore all maneuvers must be done with one hand.
Or on a trouvé, et c'est ce qui fait l'objet de la présente invention, une solution qui permet de résoudre ces problèmes, et ce sans augmentation du poids du mous¬ queton, et grâce à laquelle le grimpeur a la possibilité d'utiliser ou non le blocage du doigt et qui, lorsqu'il souhaite réaliser le blocage, permet d'effectuer cette manipulation d'une seule main, par une pression complé- mentaire du doigt de la main, sans donc gêner en aucune façon sa progression.
Par ailleurs, comme cela ressortira de la suite de la description, la réalisation technique d'un mousqueton conforme à l'invention implique l'utilisation de moyens classiques d'usinage, sans modification de l'allure géné- raie du mousqueton, et sans modifier la résistance à la rupture dudit mousqueton.Now we have found, and this is what is the subject of the present invention, a solution which makes it possible to solve these problems, and this without increasing the weight of the musket, and thanks to which the climber has the possibility of '' use or not the blocking of the finger and which, when it wishes to carry out the blocking, makes it possible to carry out this manipulation with one hand, by additional pressure of the finger of the hand, without therefore in any way hindering its progression. Furthermore, as will emerge from the following description, the technical production of a carabiner according to the invention involves the use of conventional machining means, without modifying the general appearance of the carabiner, and without modify the breaking strength of said carabiner.
D'une manière générale, l'invention concerne donc un système de fermeture avec blocage momentané entre le corps et le doigt d'un mousqueton d'escalade ou de spé¬ léologie, dont le corps comporte un relief à proximité du crochet et à l'autre extrémité un logement pour l'axe solidaire du doigt qui autorise le déplacement longitudi¬ nal de ce dernier, ledit système se caractérisant en ce que :In general, the invention therefore relates to a closure system with momentary blocking between the body and the finger of a climbing or caving carabiner, the body of which has a relief near the hook and at the 'other end a housing for the axis secured to the finger which allows the longitudinal movement of the latter, said system being characterized in that:
- la distance précise entre le relief lui-même et le logement fait sensiblement coïncider, sous la pression du ressort, la position extrême du doigt avec la position du fond de l'encoche ; - le relief est de faible dimension et comporte une rampe du côté de l'encoche ; l'association de ces deux éléments autorisant ainsi une ouverture dudit mousqueton en position de verrouillage momentané par simple pression exercée perpendiculairement au doigt.- the precise distance between the relief itself and the housing substantially coincides, under the pressure of the spring, the extreme position of the finger with the position of the bottom of the notch; - The relief is small and has a ramp on the side of the notch; the association of these two elements thus authorizing an opening of said carabiner in a momentary locking position by simple pressure exerted perpendicularly to the finger.
De préférence, conformément à l'invention :Preferably, in accordance with the invention:
- la butée est extérieure au crochet et placée à proximité de ce dernier ; - le logement est cylindrique et de diamètre supé¬ rieur à celui de 1'axe et ;- The stop is outside the hook and placed close to the latter; - The housing is cylindrical and of diameter greater than that of the axis and;
- la butée est rapportée sur le corps.
L'invention et les avantages qu'elle apporte seront cependant mieux compris grâce aux exemples de réalisation donnés ci-après à titre indicatif, mais non limitatif, et qui sont illustrés dans les schémas annexés dans les- quels :- the stopper is attached to the body. The invention and the advantages which it brings will however be better understood thanks to the exemplary embodiments given below by way of indication, but not limitation, and which are illustrated in the diagrams appended in which:
- la figure 1 présente une vue extérieure d'un mous¬ queton de l'invention selon un premier mode de réalisation ;- Figure 1 shows an exterior view of a mous¬ queton of the invention according to a first embodiment;
- la figure 2 présente un détail agrandi du crochet; - la figure 3 présente en coupe un autre détail de ce premier mode ;- Figure 2 shows an enlarged detail of the hook; - Figure 3 shows in section another detail of this first mode;
- la figure 4 présente une variante de ce premier mode ;- Figure 4 shows a variant of this first mode;
- la fiugre 5 présente un deuxième mode de réalisa- tion de l'invention.- Figure 5 presents a second embodiment of the invention.
Dans la figure 1 montrant un mousqueton de l'inven¬ tion, le doigt est articulé en (3) sur le corps (1), la goupille (5) du doigt venant, en fermeture, se placer dans le crochet (6) du corps (1). La figure 2 montre la forme originale du crochet (6) comprenant une première encoche (7) séparée de la deuxième (8) par une butée (9) , ces différentes formes étant réalisées par fraisage (à commande numérique par exemple) . Pour la clarté du des- sin, seule est représentée la goupille (5) du doigt (2), en position non verrouillée. La figure 3 décrit de quelle façon, suivant un premier mode de réalisation, le doigt (2) est articulé sur le corps (1), un ressort interne (4) s'opposant en permanence à l'ouverture du doigt. On no- tera que l'axe d'articulation (3) solidaire du doigt (2) peut se déplacer dans un trou oblong (10) réalisé dans le corps (1) (de 1mm environ).
Dans la variante du premier mode présentée à la figure 4, le trou oblong est remplacé par un troi (11) de diamètre supérieur à l'axe (3) permettant ainsi à ce dernier un déplacement possible de un millimètre environ.In FIG. 1 showing a carabiner of the invention, the finger is articulated at (3) on the body (1), the pin (5) of the finger coming, when closing, to be placed in the hook (6) of the body (1). FIG. 2 shows the original shape of the hook (6) comprising a first notch (7) separated from the second (8) by a stop (9), these different shapes being produced by milling (with numerical control for example). For the sake of clarity, only the pin (5) of the finger (2) is shown, in the unlocked position. Figure 3 describes how, according to a first embodiment, the finger (2) is articulated on the body (1), an internal spring (4) permanently opposing the opening of the finger. It should be noted that the articulation axis (3) integral with the finger (2) can move in an oblong hole (10) made in the body (1) (of about 1 mm). In the variant of the first mode presented in Figure 4, the oblong hole is replaced by a hole (11) of diameter greater than the axis (3) thus allowing the latter a possible displacement of about one millimeter.
Dans un deuxième mode de réalisation, illustré par la figure 5, la butée (12) n'est plus réalisée dans le crochet (6) , mais sur le rebord du corps (1) , le doigt (2) comportant un creux (13) destiné à venir s'engager dans la butée (12). Comme dans la figure 3, l'axe (3) solidaire du doigt (2) peut se déplacer dans une rainure oblongue du corps (1) .In a second embodiment, illustrated by FIG. 5, the stop (12) is no longer produced in the hook (6), but on the edge of the body (1), the finger (2) having a recess (13 ) intended to come and engage in the stop (12). As in Figure 3, the axis (3) integral with the finger (2) can move in an oblong groove of the body (1).
On comprend ainsi le fonctionnement de ce nouveau mousqueton : lorsque le grimpeur a introduit la corde dans le mousqueton, la goupille (5) revient en butée dans l'encoche (7) contre (9) ; il exerce alors une pression complémentaire pour forcer la goupille à franchir la butée (9). Ceci est possible car le doigt peut se dépla- cer vers le bas grâce aux trous oblong (10) ou agrandi (11), contre l'effet du ressort (4). Dès que la butée (9) est franchie, le doigt, poussé par le ressort (4), re¬ vient en position initiale dans l'encoche (8), assurant ainsi son blocage momentané. Ainsi, quelque soit la sol- licitation du doigt (choc contre le rocher ou appui de la corde ou phénomène de vibrations), celui-ci est verrouil¬ lé, apportant ainsi une grande sécurité au grimpeur. Pour ouvrir le mousqueton ainsi fermé, le grimpeur exerce une pression sur le doigt vers l'intérieur du mousqueton provoquant le franchissement de la butée (9) par efface¬ ment momentané du doigt vers le bas. On constate d'ail¬ leurs que cette invention est applicable au mousqueton quelle que soit la forme du doigt (droit ou courbé), que l'ouverture soit ou non dans le plan du mousqueton et aussi dans la disposiiton inverse, soit le crochet sur le doigt (2) et la goupille (5) sur le corps.
Cette invention permet également d'utiliser un res¬ sort (4) plus faible, ce qui est très agréable pour le grimpeur, puisque le doigt peut être verrouillé en utili¬ sation. On notera que ce nouveau mousqueton est très sûr puisque si le grimpeur oublie de verrouiller le doigt, toute chute amènera une déformation du corps (1) suffi¬ sante pour provoquer automatiquement le passage de la goupille (5) du doigt (2) dans l'encoche (8) assurant ainsi le verrouillage du mousqueton, qui est ainsi anti- choc.We thus understand the operation of this new carabiner: when the climber has introduced the rope into the carabiner, the pin (5) comes into abutment in the notch (7) against (9); it then exerts additional pressure to force the pin to pass the stop (9). This is possible because the finger can move downwards thanks to the oblong (10) or enlarged (11) holes, against the effect of the spring (4). As soon as the stop (9) is crossed, the finger, pushed by the spring (4), returns to the initial position in the notch (8), thus ensuring its momentary blocking. Thus, whatever the solicitation of the finger (impact against the rock or support of the rope or vibration phenomenon), it is locked, thus providing great safety to the climber. To open the carabiner thus closed, the climber exerts pressure on the finger towards the interior of the carabiner causing the abutment of the stop (9) by momentary erasure of the finger down. We also note that this invention is applicable to the carabiner whatever the shape of the finger (straight or curved), whether or not the opening is in the plane of the carabiner and also in the reverse arrangement, or the hook on the finger (2) and the pin (5) on the body. This invention also makes it possible to use a weaker spring (4), which is very pleasant for the climber, since the finger can be locked in use. Note that this new carabiner is very safe since if the climber forgets to lock the finger, any fall will cause deformation of the body (1) sufficient to automatically cause the passage of the pin (5) of the finger (2) in the 'notch (8) thus ensuring the locking of the carabiner, which is thus shockproof.
On ne sort pas du cadre de l'invention en réalisant une butée (9) rapportée sur le corps (1) par tous moyens, en plaçant cette butée à un endroit différent (toujours entre le corps (1) et le doigt (2)), en utilisant pour la butée des matériaux compressibles (caoutchouc par exem¬ ple), en modifiant la forme du logement (10,11) ou en remplaçant la butée (9) par une bille ; de la même façon, l'invention englobe toutes les formes que l'on peut don- ner à la butée (9) (portions de cercle, segments de droi¬ te de différentes inclinaisons) : en effet, on comprend bien qu'en jouant sur ces formes et proportions, le fa¬ bricant pourra obtenir un blocage plus ou moins dur et donc un effort pour ouvrir et fermer le mousqueton plus ou moins important (en liaison avec la force du ressort (4)).We do not depart from the scope of the invention by making a stop (9) attached to the body (1) by any means, by placing this stop in a different location (always between the body (1) and the finger (2) ), by using compressible materials (rubber for example), by modifying the shape of the housing (10,11) or by replacing the stop (9) with a ball; in the same way, the invention encompasses all the forms that can be given to the stop (9) (portions of a circle, segments of droi¬ te of different inclinations): in fact, it is well understood that playing on these shapes and proportions, the fa¬ bricant can obtain a more or less hard blocking and therefore an effort to open and close the carabiner more or less important (in connection with the force of the spring (4)).
On ne sort pas du cadre de l'invention en réalisant une disposition inverse, par exemple au niveau de l'ar- ticulation du doigt (2), en réalisant le trou oblong ou agrandi dans le doigt, l'axe (3) étant fixe sur le corpsWe do not depart from the scope of the invention by making a reverse arrangement, for example at the joint of the finger (2), by making the oblong or enlarged hole in the finger, the axis (3) being fixed on the body
(1).(1).
L'invention participe ainsi à une grande sécurité pour la pratique de l'escalade et de la spéléologie.
The invention thus contributes to great safety for the practice of climbing and speleology.
