Abstract

This automatic unhooking system for harnesses, which can be used in particular for windsurfing boards, permits rapid and easy release from the watercraft. It comprises a rigid plate (2) which is fastened to the harness (1) and is provided with fastening supports (5, 6) for a pivot (9) which is offset with regard to the plate (2) and about which a movable hook (10) can pivot. Opening of the hook is ensured by a spring (15) which presses it against the plate when the tension with the connecting element (13) which is fastened to the watercraft is removed. Quick unhooking is thereby ensured, which is facilitated by the opening position of the hook forwards and downwards. Hooking is effected as in a fixed hook without the aid of the hands by a body movement which guides the connecting element into the opening of the hook, which according to the invention goes into the closed position when it is pulled.

Description

La présente invention concerne un système d'ouverture automatique pour le crochet des harnais utilisés notamment dans la pratique de la navigation et en particulier la planche à voile. The present invention relates to an automatic opening system for the hook of harnesses used in particular in the practice of navigation and in particular windsurfing.

Les dispositifs connus permettant de réduire les efforts physiques des bras nécessaires à la pratique d'activités sportives, en particulier la planche à voile, le dériveur et le ski nautique se divisent en deux grands types : 1) Les systèmes munis de sangles de suspension que l'utilisateur doit passer dans le dos afin de diminuer la traction sur les bras. Exemples : Brevet numéro 2 442 641 et brevet numéro 2 391 748. 2) Le harnais qui comprend une ceinture de poitrine, de longueur réglable, munie de bretelles ajustables à la taille de l'utilisateur, cette ceinture étant munie au niveau du sternum d'une platine rigide possédant un crochet de fixation pour un élément de liaison largable par l'utilisateur, cet élément ayant ses extrémités fixées à une partie de l'embarcation, par exemple sur le wishbone d'une planche à voile. The known devices making it possible to reduce the physical efforts of the arms necessary for the practice of sporting activities, in particular windsurfing, the dinghy and water skiing are divided into two main types: 1) Systems provided with suspension straps that the user must pass in the back in order to decrease the traction on the arms. Examples: Patent number 2 442 641 and patent number 2 391 748. 2) The harness which includes a chest belt, of adjustable length, provided with suspenders adjustable to the size of the user, this belt being provided at the level of the sternum d 'a rigid plate having a fixing hook for a connecting element which can be released by the user, this element having its ends fixed to a part of the boat, for example on the wishbone of a windsurfing board.

le problème principal pose par ce type de harnais provient de la pièce rigide formant crochet à laquelle l'utilisateur doit sf accrocher afin de diminuer la traction des bras. Quand l'utilisateur se trouve en difficulté ou désire simplement se désolidariser de son embarcation, il éprouve souvent des difficultés à décrocher l'élément de liaison pris dans le crochet de son harnais, ce crochet étant généralement fixe sur la platine. the main problem posed by this type of harness comes from the rigid piece forming a hook to which the user must hang in order to reduce the traction of the arms. When the user finds himself in difficulty or simply wishes to dissociate himself from his boat, he often experiences difficulties in unhooking the connecting element caught in the hook of his harness, this hook being generally fixed on the plate.

Les perfectionnements apportés par le dispositif breveté sous les numéros 2 345 172 et 2 373 295 apportent une solution au problè- me du largage de l'élément de liaison. La pièce de fixation est for ée dans ce cas d'un crochet ouvert, monté sur un pivot bloque par un pontet permettant d'obtenir une position fermée, ou position d' accrochage et une position ouverte ou position de décrochage, celuici étant obtenu. rrâce à une traction sur une ligne fixée cénérale- ment au poignet de l'utilisateur. The improvements made by the patented device under the numbers 2 345 172 and 2 373 295 provide a solution to the problem of the release of the connecting element. The fixing piece is for ée in this case of an open hook, mounted on a pivot blocked by a trigger guard allowing to obtain a closed position, or hooking position and an open position or stalling position, this being obtained. rThrough a traction on a line cenerally fixed to the user's wrist.

l'inconvénient principal de ce perfectionnement provint de cette ligne fixée au poignet qui gène les mouvements de l'utilisateur : pour ne pas régner ces mouvements, il faut que la ligne soit très détendue, mais dans ce cas, la traction nécessaire au décrochage du système devient très difficile à effectuer. the main drawback of this improvement came from this line attached to the wrist which hinders the movements of the user: to avoid reigning these movements, the line must be very relaxed, but in this case, the traction required to unhook the system becomes very difficult to perform.

le système de crochet de harnais selon l'invention permet d'éviter ces inconvénients. l'utilisateur est totalement libre de ses mouvements, aucune ligne n'étant pessaire au largage de l'elément de liaiscn : Grâce à un ressort ramenant le crochet en po@i- tion ouverte, seul un relachement de la tension assure le largage de l'élément de liaison.Le système d'accrochage pour sa part ne diffère pas de celui d'un harnais a crochet fixe, la position d' ouverture du crochet vers le bas et vers l'avant permettant une mise en place de l'élément de liaison dans ce crochet, sans l'aide des mains, par un mouvement du corps qui amène l'élément de liaison dans l'ouverture du crochet qui, dans l'invention, se place en position de fermeture dès sue l'on exerce sur lui une tension. the harness hook system according to the invention makes it possible to avoid these drawbacks. the user is completely free to move, no line being necessary for the release of the connecting element: Thanks to a spring bringing the hook back into open position, only a release of the tension ensures the release of the connecting element. The attachment system for its part does not differ from that of a harness with fixed hook, the position of opening of the hook downwards and forwards allowing a positioning of the connecting element in this hook, without the help of the hands, by a movement of the body which brings the connecting element into the opening of the hook which, in the invention, is placed in the closed position as soon as one exerts tension on him.

Le système d'accrochage du harnais de soutien sur l'élément de liaison solidaire de l'embarcation est constitué d'une platine riglde sur laquelle sont fixées, au centre, deux pattes parallèles l'une à l'autre et perpendiculaire à la platine. Ces deux pattes sont percées à l'avant par deux trous dans lesquels passe un axe mobile ou non par rapport aux pattes. Sur cet axe et perpendiculaire a la platine vient s'artiouler un élément rigide de forme recourbée en demi-cercle, formant crochet, solidaire ou non de l'axe, mais nécessairement mobile par rapport aux pattes.Entre la partie fixe constituée par l'ensemble platine-pattes et le crochet mobile vient
e placer un ressort ou tout autre forme de pièce mécanique à propriétés élastiques (comme une lame métallique semi-rigide ou un élastique) permettant de croduire un mouvement suffisant pour pla quer l'anse du crochet, lorsqu'il n'est pas fixe à l'élément de liaison, contre la partie supérieure de la platine.L'ouverture du demi-cercle se trouvant alors vers le bas et légèrement vers l'avant par rapport à la poitrine de l'utilis@teur, l'angle formé entre l'axe de symétrie du demi-cercle formant crochet et l'horizontale étant alors d'environ 120 degrès, Lorsque l'utilisateur vient placer dans le crochet l'élément de liaison, l'élasticité du ressort doit être suffisamment faible pour permettre au crochet de pivoter sur l'axe et de se placer ainsi dans une position qui empêche le largage de l'élément de liaison ; l'angle formé entre l'axe de symétrie du demi-cercle formant crochet et l'horizontal étant alors inférieur à @@ degrès, Dès que l'utilisateur relâche la tension exercée entre le crochet et l'élément de liaison, par exe.vDle en rapprochant de lui le wishbone de sa planche à voile, le ressort ramene le crochet dans sa position d'ouverture, l'anse du crochet contre la partie supérieure de la platine.
The system for attaching the support harness to the connecting element integral with the boat consists of a rigid plate on which are fixed, in the center, two legs parallel to each other and perpendicular to the plate . These two legs are pierced at the front by two holes through which passes a movable axis or not relative to the legs. On this axis and perpendicular to the plate is articulated a rigid element of curved shape in a semicircle, forming a hook, integral or not with the axis, but necessarily movable relative to the legs. Between the fixed part constituted by the set of legs and legs and the movable hook comes
e place a spring or any other form of mechanical part with elastic properties (such as a semi-rigid metal blade or an elastic band) allowing sufficient movement to be applied to place the hook handle when it is not fixed to the connecting element, against the upper part of the plate. The opening of the semicircle then being located downwards and slightly forward with respect to the chest of the user, the angle formed between the axis of symmetry of the semicircle forming the hook and the horizontal then being approximately 120 degrees, When the user places the connecting element in the hook, the elasticity of the spring must be sufficiently low to allow the hook to pivot on the axis and thus to be placed in a position which prevents the release of the connecting element; the angle formed between the axis of symmetry of the semicircle forming the hook and the horizontal then being less than @@ degrees, As soon as the user releases the tension exerted between the hook and the connecting element, for example. vDle by bringing the wishbone closer to its windsurf board, the spring returns the hook to its open position, the hook handle against the upper part of the plate.

Il est conné à titre d'exemple non limitatif un mode de réali @ation se réfé@an@ aux figure@ I et II ci-annexées (planche unique). It is known by way of nonlimiting example a mode of realization referred to @ an @ to the figures @ I and II attached (single plate).

la figure @ représente l'ensemble du système monté sur un har nais de soutien classique. La sangle ventrale ou thoracique (1) du harnais de soutien supporte une platine métallique (2) par deux orifices (3) et (4) pour le passage des sangles. Au centre de la platine et distantes de un centimètre sont soudées deux pattes (5) et (6) de deux centimètres de long pour un centimètre de large. Au centre de la moitié avant de chacune. de ces pattes est percé un trou (7) et (8) par lequel passe un axe (9), soudé sur les pattes dans ce mode de réalisation. Autour de cet axe vient se placer l'ex trématé en forme de boucle fermée du crochet (10) du harnais forme ici d'une partie droite suivie d'un demi-cercle. Autour de cet axe s'enroule également un fil métallique formant ressort.L'une de,s extrémistes recourbées de ce fil métallique s'appuie en (11) sur la partie initiale du crochet et l'autre en (12) sur le bord inférieur d'une des deux pattes de soutien. Lorsque le harnais est en position d'accrochage, représentée ici en pointillés, le crochet est retenu dans l'élément de liaison constitue dans ce mode de réalisation par une cordelette (13) fixée à chacune de ses extrémités sur le wishbone dans le cas d'une planche à voile. Figure @ shows the entire system mounted on a conventional support harness. The ventral or thoracic strap (1) of the support harness supports a metal plate (2) by two holes (3) and (4) for the passage of the straps. In the center of the plate and separated by one centimeter are welded two tabs (5) and (6) two centimeters long by one centimeter wide. In the center of the front half of each. a hole (7) and (8) is pierced from these legs, through which an axis (9) passes, welded to the legs in this embodiment. Around this axis is placed the ex-tremat in the form of a closed loop of the hook (10) of the harness here formed of a straight part followed by a semicircle. Around this axis is also wound a metal wire forming a spring. One of the extremists bent over this metal wire is supported in (11) on the initial part of the hook and the other in (12) on the edge. lower of one of the two support legs. When the harness is in the hooking position, shown here in dotted lines, the hook is retained in the connecting element constitutes in this embodiment by a cord (13) fixed at each of its ends on the wishbone in the case of 'a windsurfing.

La figure II représente le système proprement dit permettant le retour du crochet en position d'ouverture. Une seule des deux pattes de fixation (5) est représentée ici. Elle soutient un axe (9) autour duquel vient se placer l'extremite en forme de boucle fermée (14) du crochet (10). Autour de cet axe s'enroule également un fil métallique (15) formant ressort. L'une des extrémités recourbée de ce fil métallique s'appuie en (11) sur la partie initiale du crochet et l'autre en (12) sur le bord inférieur d'une des pattes de sotie.  Figure II shows the system itself for returning the hook to the open position. Only one of the two fixing lugs (5) is shown here. It supports an axis (9) around which is placed the end in the form of a closed loop (14) of the hook (10). Around this axis is also wound a metal wire (15) forming a spring. One of the curved ends of this metal wire is supported in (11) on the initial part of the hook and the other in (12) on the lower edge of one of the tabs.

On pourrait facilement etendre le domaine d'application de cette invention à toutes les activités sportives ou autres qui utilisent un harnais de soutien nécessitant un largage rapide et facile de l'é- liment de liaison sans utiliser directement l'aide des mains, comme par exemple pour le dériveur à voile et le ski nautique. The field of application of this invention could easily be extended to all sports or other activities which use a support harness requiring quick and easy release of the binding element without directly using the aid of the hands, as for example. example for sailing dinghy and water skiing.

L'avantage de cette invention réside essentiellement dans la facilité de largage de l'élément ce liaison qui écoule de la Fcsi- tion d'ouverture du crochet vers l'avant et vers le bas, position qui élimine les risques tour l'utilisateur de rester solida-re dé son embarcation lorsqu'il désire s'en libérer, mais elle réside aussi dans la rapidité du décrochage obtenue grâce au ressort qui plaque instantanément le crochet en position d'ouverture dès que l'utilisateur relâche la tensi@. sur l'élément de liaison.  The advantage of this invention lies essentially in the ease of dropping the element, this connection which flows from the opening of the hook forward and downward, a position which eliminates the risks for the user. stay solida re re his boat when he wants to free himself, but it also lies in the speed of the stall obtained by the spring which instantly places the hook in the open position as soon as the user releases the tensi @. on the connecting element.
