Description
Dispositif d'accrochage déverrouillable sous charge pour ceinture trapèze pour la pratique de la voile La présente invention concerne un dispositif d'accrochage déverrouillable sous charge pour ceinture de trapèze pour la pratique de la voile, et notamment pour la pratique de la voile sur des embarcations légères. Pour augmenter le couple de rappel de l'équipage constitué par une ou plusieurs personnes, afin de maintenir l'assiette d'un dériveur, d'un catamaran de sport, ou d'une planche à voile, le plus à l'horizontal possible, lorsque le vent devient fort, le barreur et le ou les équipiers ont recours à l'utilisation dite du trapèze. A cet effet, le ou chaque équipier est équipé d'une ceinture munie d'un crochet situé au niveau de l'abdomen. Ce crochet permet le passage d'une boucle métallique fixée à une extrémité d'un câble dont l'autre extrémité est fixée sur le mât, lorsqu'il s'agit d'un voilier. En l'absence de tension exercée sur le crochet, la boucle solidaire du câble peut s'échapper aisément du crochet, permettant de libérer l'équipier pour effectuer les manœuvres nécessaires, et notamment pour changer de bord. Cependant, si le câble reste en tension, ou si le crochet s'accroche à un accessoire autre que la boucle, l'équipier peut ne pas pouvoir se détacher de la boucle, et se trouver dans une situation délicate. Des accidents peu nombreux mais parfois mortels, se produisent, quel que soit le niveau de compétence des pratiquants. Ces accidents surviennent souvent lorsque les bateaux se retournent, et que les équipiers tombent à l'eau. Les équipiers peuvent alors se trouver coincés sous le bateau ou sous les voiles, sans possibilité de se dégager, bloqués par la tension du câble de trapèze qui empêche la libération du crochet. Dans d'autres cas, un équipier, en tombant du bateau, peut se trouver suspendu par le crochet à une corde en tension dans le bateau. Cet accessoire peut être le haie bas dans le cas d'un dériveur, ou le transfilage du trampoline dans le cas d'un catamaran. Quelle que soit la situation, le point commun est que l'équipier dispose d'un délai très court pour se libérer avant d'être coincé sous l'embarcation, dont il contribue souvent, par son propre poids, à accélérer le chavirement. Les situations à risque se multiplient aujourd'hui, dans la mesure où il existe un nombre de plus en plus important d'embarcations qui sont de plus en plus rapides et instables, et qui requièrent l'utilisation du trapèze tant pour le ou les équipiers que pour le barreur, dans le cadre d'une pratique en solitaire ou en double.
Certains accidents ont conduit des clubs de voile à renoncer à utiliser les ceintures de trapèze dans certaines conditions de vent et de mer, pour prévenir les accidents, même si ces conditions sont précisément celles dans lesquelles ce type d'équipement est le plus utile. Le but de l'invention est de fournir un dispositif d'accrochage déverrouillable sous charge, pour ceinture de trapèze, grâce auquel l'équipier portant une telle ceinture, peut se libérer de façon immédiate, dans un geste réflexe, y compris lorsque le crochet exerce une tension sur le câble relié au mât ou sur un autre accessoire appartenant à la structure de l'embarcation. A cet effet, le dispositif, qu'elle concerne, comprend : - un corps de forme aplatie solidaire d'une barre de harnais recevant un jeu de sangles permettant à un équipier de s'équiper en ayant la barre de harnais sur l'abdomen, le corps étant disposé dans le plan médian longitudinal de la barre et tourné vers l'avant, - un crochet monté pivotant sur la partie avant du corps, autour d'un axe transversal au corps, ce crochet comportant, en dessous de son axe d'articulation, d'une part du côté avant une partie courbe en forme de crochet ouvert vers le bas et d'autre part du côté arrière un bec comportant un évidement ouvert vers le bas, - un ressort en épingle dont les deux extrémités des branches, tournées l'une vers l'autre sont engagés dans des trous du corps décalés tendant à faire pivoter l'ensemble du ressort vers l'avant, de telle sorte que la partie centrale du ressort vienne assurer le verrouillage du crochet en venant prendre appui dans l'évidement du bec de celui-ci, et - un levier articulé sur le corps autour d'un axe parallèle à l'axe du crochet et situé au dessus de celui-ci, comportant une partie supérieure, au- dessus de l'axe, tournée vers le haut et vers l'avant, et une partie inférieure tournée vers le bas et vers l'arrière, dont l'extrémité inférieure prend appui contre la face tournée vers l'avant, des branches du ressort en épingle. Le crochet étant ouvert vers le bas, un équipier muni d'une ceinture comportant ce dispositif s'accroche de façon rapide en engageant le crochet sur une boucle ou similaire solidaire d'un câble fixé au mât. En position de verrouillage du crochet, celui-ci est maintenu dans sa position de verrouillage par appui de la partie centrale du ressort en épingle contre le bec que comporte la partie arrière du crochet.
Lorsque l'équipier muni de cette ceinture de trapèze souhaite libérer sous charge le crochet, il exerce une pression vers l'avant sur la partie supérieure du levier articulé, la partie inférieure du levier faisant basculer la partie inférieure du ressort en épingle autour des points d'articulation de ce ressort, de telle sorte que le ressort libère le bec de la partie arrière du crochet qui peut ainsi librement pivoter autour de son axe d'articulation sur le corps. Avantageusement, l'axe d'articulation du crochet est monté transversalement dans une pièce cylindrique, elle-même montée pivotante dans le corps autour d'un axe orthogonal à l'axe d'articulation du crochet. Cette caractéristique assure la possibilité, après dégagement du bec de la partie arrière du crochet hors de l'épingle ressort, de permettre un pivotement de l'ensemble du crochet autour d'un axe transversal à l'axe de rotation du crochet sur le corps. On dispose ainsi d'une double rotation, à la façon d'un joint de cardan, ce qui améliore considérablement la sécurité, car permettant une libération du crochet hors de la boucle d'accrochage, quelle que soit l'orientation du câble exerçant une tension sur le crochet. Suivant une caractéristique intéressante de l'invention, la face inférieure du corps possède une section en U ouvert vers le bas, dans laquelle vient s'encastrer le crochet en position verrouillée de celui-ci par le ressort. Ainsi, en position de verrouillage, le crochet est maintenu par la partie inférieure du corps, et ne peut donc pivoter autour de l'axe orthogonal à l'axe principal de rotation du crochet. Suivant une forme d'exécution de ce dispositif, le corps possède une forme générale de C ouvert vers l'avant, entre les branches duquel est monté un support pour l'articulation du crochet. Avantageusement, l'axe du levier est monté dans une lumière allongée ménagée dans le corps et orientée de haut en bas et d'avant en arrière sensiblement dans le prolongement de laquelle se trouve un évidement ménagé dans la partie inférieure du corps et dans lequel est destinée à venir s'engager l'extrémité inférieure du levier en position ouverte du crochet et en position escamotée du ressort. Ainsi, lorsque l'équipier exerce une poussée sur le levier de déverrouillage, ce levier, non seulement pivote autour de son axe de rotation, mais encore l'axe de rotation se décale vers le bas dans la lumière, jusqu'à ce que le levier vienne occuper une position verrouillée, son extrémité inférieure se trouvant alors dans l'évidement ménagé dans la partie inférieure du corps.
Dans cette position, le levier maintient donc le ressort en position d'ouverture, et ne permet le réenclenchement du bec de la partie postérieure du crochet et du ressort. Ainsi, le crochet ne peut-il être actionné de façon accidentelle vers sa position de verrouillage. Pour reverrouiller le crochet, il convient d'exercer une action volontaire consistant à faire basculer le crochet vers sa position de verrouillage, puis à déplacer le levier vers l'avant et vers le haut pour libérer le ressort, et permettre l'engagement de celui-ci derrière le bec de la partie postérieure du crochet. De toute façon l'invention sera bien comprise, à l'aide de la description qui suit, en référence au dessin schématique annexé, représentant, à titre d'exemple non limitatif, une forme d'exécution de ce dispositif d'accrochage pour ceinture de trapèze. Figure 1 est une vue en perspective de ce dispositif de trois quart arrière en position verrouillée. Figures 2 et 3 sont deux vues de côté de ce dispositif, respectivement en position verrouillée et en position déverrouillée. Figure 4 est une vue de côté du corps du dispositif d'accrochage. Le dispositif d'accrochage représenté au dessin comprend une barre de harnais 2 constituée par une structure tubulaire, destinée à recevoir un jeu de sangles, non représentées, permettant à un équipier de s'équiper en ayant la barre de harnais positionnée sur l'abdomen. Sur cette barre de harnais, est fixé un corps 3, de forme aplatie, disposé dans le plan médian longitudinal de la barre, se présentant sous la forme d'une pièce de section en C ouvert vers l'avant. La fixation du corps sur la barre de harnais est réalisée par engagement de deux éléments tubulaires, respectivement supérieur et inférieur de la barre, dans deux évidements respectivement 4 et 5 du corps. L'extrémité avant du corps est équipée d'un support 6 fermant l'ouverture du C, ce support 6 présentant une ouverture 7 centrale de section circulaire, tournée vers l'avant. Cette ouverture 7 de section circulaire sert au montage pivotant d'une pièce cylindrique 8. Sur la partie avant de cette pièce 8, est monté pivotant autour d'un axe 9 orthogonal à l'axe autour duquel peut pivoter la pièce 8 vis-à-vis du support 9, une pièce 10 formant crochet.The present invention relates to an unlockable hanging device under load for a trapeze belt for the practice of sailing, and in particular for the practice of sailing on boats. light. To increase the return torque of the crew made up of one or more people, in order to maintain the trim of a dinghy, a sport catamaran, or a windsurf board, as horizontal as possible , when the wind becomes strong, the coxswain and the team member (s) use the so-called trapeze. For this purpose, the or each team member is equipped with a belt provided with a hook located at the level of the abdomen. This hook allows the passage of a metal loop fixed to one end of a cable whose other end is fixed to the mast, when it is a sailboat. In the absence of tension exerted on the hook, the loop integral with the cable can easily escape from the hook, making it possible to free the team member to perform the necessary maneuvers, and in particular to change the edge. However, if the cable remains under tension, or if the hook hangs on an accessory other than the loop, the team member may not be able to detach from the loop, and be in a delicate situation. Few but sometimes fatal accidents occur regardless of the skill level of the practitioners. These accidents often occur when boats overturn, and crew members fall into the water. Team members can then be trapped under the boat or under the sails, without the possibility of getting free, blocked by the tension of the trapeze cable which prevents the release of the hook. In other cases, a team member, falling from the boat, may find himself hanging by the hook on a rope in tension in the boat. This accessory can be the low hedge in the case of a dinghy, or the transfiling of the trampoline in the case of a catamaran. Whatever the situation, the common point is that the team member has a very short time to free himself before being trapped under the boat, which he often contributes, by his own weight, to accelerate the capsizing. Risk situations are multiplying today, to the extent that there are an increasing number of boats which are more and more rapid and unstable, and which require the use of the trapeze for both the crew member (s) as for the coxswain, as part of a solo or double practice. Some accidents have led sailing clubs to give up using trapeze belts in certain wind and sea conditions, to prevent accidents, even if these conditions are precisely those in which this type of equipment is most useful. The object of the invention is to provide an unlockable hanging device under load, for a trapeze belt, by means of which the team member wearing such a belt can be released immediately, in a reflex gesture, including when the hook exerts tension on the cable connected to the mast or on another accessory belonging to the structure of the boat. To this end, the device, which it relates to, comprises: - a flattened body secured to a harness bar receiving a set of straps allowing a team member to equip themselves with the harness bar on the abdomen , the body being disposed in the longitudinal median plane of the bar and turned towards the front, - a hook pivotally mounted on the front part of the body, around an axis transverse to the body, this hook comprising, below its axis articulation, on the one hand on the front side a curved hook-shaped part open at the bottom and on the other hand on the rear side a spout comprising a recess open at the bottom, - a pin spring whose two ends of the arms, facing towards each other are engaged in offset body holes tending to pivot the entire spring forwards, so that the central part of the spring comes to lock the hook in coming support in the recess of the spout d e the latter, and - a lever articulated on the body around an axis parallel to the axis of the hook and situated above the latter, comprising an upper part, above the axis, facing the top and forward, and a bottom portion facing downward and backward, the lower end of which bears against the forward facing face, of the branches of the pin spring. The hook being open downwards, a team member provided with a belt comprising this device hooks quickly by engaging the hook on a loop or the like secured to a cable fixed to the mast. In the hook locking position, the latter is held in its locking position by pressing the central part of the pin spring against the spout which the rear part of the hook comprises. When the team member equipped with this trapeze belt wishes to release the hook under load, he exerts pressure forward on the upper part of the articulated lever, the lower part of the lever tilting the lower part of the pin spring around the points of articulation of this spring, so that the spring releases the spout of the rear part of the hook which can thus freely pivot around its axis of articulation on the body. Advantageously, the axis of articulation of the hook is mounted transversely in a cylindrical piece, itself pivotally mounted in the body around an axis orthogonal to the axis of articulation of the hook. This characteristic ensures the possibility, after releasing the spout from the rear part of the hook out of the spring pin, to allow the whole hook to pivot around an axis transverse to the axis of rotation of the hook on the body . There is thus a double rotation, in the manner of a universal joint, which considerably improves safety, since it allows the hook to be released from the hooking loop, whatever the orientation of the cable exerting a tension on the hook. According to an advantageous characteristic of the invention, the underside of the body has a U-shaped section open downwards, in which the hook is fitted in the locked position of the latter by the spring. Thus, in the locked position, the hook is held by the lower part of the body, and cannot therefore pivot around the axis orthogonal to the main axis of rotation of the hook. According to an embodiment of this device, the body has a general shape of C open towards the front, between the branches of which is mounted a support for the articulation of the hook. Advantageously, the axis of the lever is mounted in an elongated opening formed in the body and oriented from top to bottom and from front to back substantially in the extension of which is a recess formed in the lower part of the body and in which is intended to come to engage the lower end of the lever in the open position of the hook and in the retracted position of the spring. Thus, when the team member pushes the unlocking lever, this lever not only pivots about its axis of rotation, but also the axis of rotation shifts downward in the light, until the lever comes to occupy a locked position, its lower end then being in the recess in the lower part of the body. In this position, the lever therefore maintains the spring in the open position, and does not allow reclosing of the spout of the rear part of the hook and of the spring. Thus, the hook cannot be accidentally actuated towards its locking position. To relock the hook, it is necessary to exert a voluntary action consisting in tilting the hook towards its locked position, then moving the lever forwards and upwards to release the spring, and allow the engagement of that -this behind the spout of the rear part of the hook. In any case, the invention will be clearly understood, with the aid of the description which follows, with reference to the appended diagrammatic drawing, representing, by way of nonlimiting example, an embodiment of this hanging device for a belt. trapeze. Figure 1 is a perspective view of this three quarter rear device in the locked position. Figures 2 and 3 are two side views of this device, respectively in the locked position and in the unlocked position. Figure 4 is a side view of the body of the attachment device. The attachment device shown in the drawing comprises a harness bar 2 constituted by a tubular structure, intended to receive a set of straps, not shown, allowing a team member to be equipped by having the harness bar positioned on the abdomen . On this harness bar, is fixed a body 3, of flattened shape, arranged in the longitudinal median plane of the bar, being in the form of a piece of C section open towards the front. The body is fixed on the harness bar by engagement of two tubular elements, respectively upper and lower of the bar, in two recesses 4 and 5 respectively of the body. The front end of the body is equipped with a support 6 closing the opening of the C, this support 6 having a central opening 7 of circular section, facing forward. This opening 7 of circular section is used for the pivoting mounting of a cylindrical part 8. On the front part of this part 8, is pivotally mounted about an axis 9 orthogonal to the axis around which the part 8 can pivot opposite. screw of the support 9, a piece 10 forming a hook.
L'articulation de cette pièce 10 est réalisée à l'aide d'une chape dont les deux ailes sont engagées sur la pièce cylindrique 8, et sont associées à celle-ci par l'axe 9. La pièce 10 formant crochet, possède, en dessous de l'axe
d'articulation et du côté de son extrémité avant une partie courbe 12 ouverte vers le bas et servant à l'accrochage sur une boucle solidaire d'un câble appartenant à l'embarcation. Cette pièce 10 comporte, du côté de son extrémité arrière, un bec 13 présentant un évidement 14 tourné vers le bas. Sur la partie postérieure du corps 3, est monté un ressort en épingle 15 dont les deux extrémités des branches, tournées l'une vers l'autre sont engagées dans des trous 16 décalés l'un par rapport à l'autre, ménagés dans le corps, ce décalage tendant à faire pivoter l'ensemble du ressort vers l'avant. De cette façon, lorsque le crochet 10 est en position de verrouillage, la partie centrale du ressort 15 vient coiffer le bec 13 du crochet 10, et vient prendre appui dans l'évidement 14 de ce bec. Ce dispositif d'accrochage comprend également un levier 11 monté articulé sur le corps 3 autour d'un axe 17. Ce levier comporte une partie supérieure 18 situé au dessus de l'axe 17, tourné vers le haut et vers l'avant, et une partie inférieure 19, tournée vers le bas et vers l'arrière, dont l'extrémité inférieure prend appui contre la face tournée vers l'avant des branches du ressort en épingle 15. L'axe 17 est monté articulé dans une lumière allongée 20 du corps, cette lumière étant orientée de haut en bas et d'avant en arrière. Sensiblement dans le prolongement de cette lumière, est ménagé dans le corps un évidement 22, tourné vers le haut, dans lequel est destiné à venir s'engager l'extrémité inférieure 19 du levier, lorsque l'axe 17 du levier est en position basse dans la lumière 20. Le fonctionnement de ce dispositif d'accrochage est le suivant. Dans la position représentée aux figures 1 et 2, le dispositif est en position verrouillée. Un équipier dont la ceinture de trapèze est équipée de ce dispositif peut accrocher la partie courbe 12 du crochet 10 à une boucle solidaire d'un câble fixé au mât de l'embarcation, en engageant la boucle derrière la partie courbe du crochet. La tension exercée sur le câble par le crochet maintient celui-ci dans la boucle. Dans le mesure où il s'agit de déverrouiller le dispositif alors qu'une traction est exercée par le crochet sur le câble, l'équipier exerce sur la partie supérieure 18 du levier 11 une pression de l'avant vers l'arrière. Cette action va se traduire par un pivotement de l'ensemble du levier 11 autour de l'axe 17, et par un déplacement de l'axe 17 de la partie haute de la lumière 20 vers la partie basse de celle-ci. Au cours de ce mouvement, le ressort 15 pivote de
telle sorte que sa partie centrale libère le bec 13 du crochet 10, la partie inférieure 19 du levier venant s'engager dans l'évidement 22 du corps pour maintenir le ressort en position de déverrouillage. Le crochet 10 commence à basculer autour de l'axe 9, et sa partie centrale échappant à la partie profilée en U du corps, permet le pivotement autour de l'axe de la pièce cylindrique 8, axe orthogonal à l'axe 9 d'articulation du crochet sur cette même pièce. Ainsi, la partie courbe 12 du crochet 10 peut échapper à la boucle du câble, ou à un autre accessoire de l'embarcation sur laquelle cette partie courbe exercerait une tension. Pour ramener le dispositif en position de verrouillage, il convient de faire pivoter le crochet 10 vers sa position de verrouillage, puis d'agir sur le levier 11 pour le déplacer vers le haut, l'axe 17 étant déplacé vers la partie haute de la lumière 20, afin de libérer le ressort 15 qui, sous l'effet de son élasticité, vient coiffer le bec 13 et maintenir le crochet en position de verrouillage, comme montrer aux figures 1 et 2. Comme il ressort de ce qui précède, l'invention apporte une grande amélioration à la technique existante, en fournissant un dispositif de structure simple, pouvant actionner de façon immédiate par un équipier, même dans des conditions très difficiles, et permettant un déverrouillage du crochet quelque soit la direction d'exercice de la force sur la partie courbe du crochet. Comme il va de soi, l'invention ne se limite pas à la seule forme d'exécution de ce dispositif, décrite ci-dessus à titre d'exemple, elle en embrasse au contraire toutes les variantes. C'est ainsi notamment que le crochet 10 pourrait pivoter autour d'un seul axe sur le corps, ou encore que le levier de commande de l'ouverture pourrait être monté pivotant autour d'un axe fixe vis-à-vis du corps, sans que l'on sorte pour autant du cadre de l'invention.
The articulation of this part 10 is carried out using a yoke whose two wings are engaged on the cylindrical part 8, and are associated with the latter by the axis 9. The part 10 forming a hook, has, below the axis articulation and on the side of its front end a curved portion 12 open downward and used for attachment to a loop secured to a cable belonging to the boat. This part 10 comprises, on the side of its rear end, a spout 13 having a recess 14 facing downwards. On the rear part of the body 3, a pin spring 15 is mounted, the two ends of the branches of which, facing one another, are engaged in holes 16 offset from one another, formed in the body, this offset tending to rotate the entire spring forward. In this way, when the hook 10 is in the locking position, the central part of the spring 15 covers the spout 13 of the hook 10, and comes to bear in the recess 14 of this spout. This attachment device also comprises a lever 11 mounted articulated on the body 3 around an axis 17. This lever comprises an upper part 18 situated above the axis 17, turned upwards and forwards, and a lower part 19, turned downwards and backwards, the lower end of which bears against the front-facing face of the branches of the hairpin spring 15. The pin 17 is mounted articulated in an elongated slot 20 of the body, this light being oriented from top to bottom and from front to back. Significantly in the extension of this light, is formed in the body a recess 22, turned upwards, in which is intended to engage the lower end 19 of the lever, when the axis 17 of the lever is in the low position. in the lumen 20. The operation of this attachment device is as follows. In the position shown in Figures 1 and 2, the device is in the locked position. A team member whose trapeze belt is fitted with this device can hook the curved part 12 of the hook 10 to a loop secured to a cable fixed to the mast of the boat, by engaging the loop behind the curved part of the hook. The tension exerted on the cable by the hook keeps it in the loop. Insofar as it is a question of unlocking the device while a traction is exerted by the hook on the cable, the team member exerts on the upper part 18 of the lever 11 a pressure from the front to the rear. This action will result in a pivoting of the assembly of the lever 11 around the axis 17, and by a displacement of the axis 17 from the upper part of the lumen 20 towards the lower part thereof. During this movement, the spring 15 pivots by so that its central part releases the spout 13 from the hook 10, the lower part 19 of the lever engaging in the recess 22 of the body to keep the spring in the unlocked position. The hook 10 begins to tilt around the axis 9, and its central part escaping from the U-shaped part of the body, allows pivoting around the axis of the cylindrical part 8, axis orthogonal to the axis 9 of articulation of the hook on this same part. Thus, the curved part 12 of the hook 10 can escape the cable loop, or another accessory of the boat on which this curved part would exert tension. To return the device to the locking position, it is necessary to pivot the hook 10 towards its locking position, then act on the lever 11 to move it upwards, the axis 17 being moved towards the upper part of the lumen 20, in order to release the spring 15 which, under the effect of its elasticity, comes to cap the spout 13 and maintain the hook in the locking position, as shown in FIGS. 1 and 2. As is clear from the above, the he invention brings a great improvement to the existing technique, by providing a device of simple structure, which can be actuated immediately by a team member, even under very difficult conditions, and allowing an unlocking of the hook whatever the direction of exercise of the force on the curved part of the hook. It goes without saying that the invention is not limited to the sole embodiment of this device, described above by way of example, on the contrary, it embraces all of its variants. Thus in particular that the hook 10 could pivot around a single axis on the body, or that the control lever of the opening could be pivotally mounted around a fixed axis with respect to the body, without thereby departing from the scope of the invention.
