Description

" Système et dispositif d'enroulement de voile triangulaire " "Triangular sail winding system and device"
La présente invention se rapporte à un dispositif d'enroulement et à un système de voile d'avant qui permet d'enrouler une voile, notamment une voile d'avant, généralement triangulaire, ayant un fort creux.The present invention relates to a winding device and to a front sail system which makes it possible to wind a sail, in particular a forward sail, generally triangular, having a strong hollow.
Une telle voile, est disposée entre le mat et l'étrave. Les voiles d'avant asymétriques sont généralement classée en quatre catégories: les focs, les génois, les gennakers et les spinnakers (spi) asymétriques, par ordre de creux croissant. Les focs et génois ont un guindant relié sur toute sa longueur à un câble tendu entre le pont et le mât. Les gennakers ont généralement un câble intégré à leur guindant. Au contraire, les spis ont un guindant libre, c'est-à-dire que le guindant n'est tenu que par le point d'amure et le point de drisse. Une voile de type gennaker ou spi n'est pas plate, elle présente un creux qui améliore le rendement de la voile, lorsque celle-ci est utilisée à des allures spécifiques adaptées. Lorsqu'elle est posée à plat, le guindant d'une telle voile présente une forme convexe, ce qui aide à former le creux lorsque la voile est en service.Such a sail is arranged between the mat and the bow. Asymmetric sails are generally classified into four categories: asymmetric jibs, genoa, gennakers and spinnakers (spinnakers), in order of increasing hollow. The jibs and genoa have a luff connected all along its length to a cable stretched between the deck and the mast. Gennakers usually have a cable built into their luff. On the contrary, the spinnakers have a free luff, that is to say that the luff is held only by the tack and the point of halyard. A gennaker or spinnaker type sail is not flat, it has a hollow that improves the performance of the sail, when it is used at specific adapted speeds. When laid flat, the luff of such a sail has a convex shape, which helps to form the hollow when the sail is in use.
Généralement, une voile d'avant n'est pas utilisée en permanence, d'autant qu'une voile donnée est adaptée à une allure spécifique et doit donc être changée lorsqu'elle n'est plus adaptée à l'allure du bateau. Pour un foc ou un génois, on utilise généralement un enrouleur, c'est-à-dire un dispositif qui permet l'enroulement de la voile autour du câble ou d'un tube monté autour du câble. Cependant, plus le creux est important et plus l'excédent de tissus correspondant au creux est important. De nombreux plis sont donc susceptibles de se former lors de l'enroulement. Ceci donne un effet "bouffant" à la voile enroulée, même lorsque l'enroulement est complet. La voile risque d'être endommagée, et offre une grande prise au vent. Notamment pour un spi, le creux est tel qu'un enroulement ne peut pas être envisagé.Generally, a forward sail is not used permanently, especially since a given sail is adapted to a specific pace and must therefore be changed when it is no longer adapted to the pace of the boat. For a jib or a genoa, it is generally used a winder, that is to say a device that allows the winding of the sail around the cable or a tube mounted around the cable. However, the larger the trough, the larger the tissue surplus corresponding to the trough. Many folds are likely to form during winding. This gives a "baggy" effect to the coiled sail, even when the winding is complete. The sail may be damaged, and offers great wind resistance. Especially for a spinnaker, the hollow is such that a winding can not be envisaged.
Le but de l'invention est donc de proposer une solution pour l'enroulement de voiles à fort creux. Selon l'invention, une telle solution est apportée par un dispositif d'enroulement pour voile sensiblement triangulaire, qui peut être une voile d'avant asymétrique, comprenant:The object of the invention is therefore to propose a solution for the winding of high-void sails.

La figure 1 représente l'avant d'un voilier 1. Ce voilier comprend un coque 2 et un mât 3. Un voile d'avant asymétrique 4 est représentée en service. Un bord de la voile le plus en avant, c'est-à-dire le bord d'attaque, est appelé le guindant 40. La voile 4 est maintenue entre trois points, respectivement un point d'amure 41 , à l'extrémité basse du guindant, un point de drisse 42, à l'extrémité haute du guidant, et un point d'écoute 43, à un angle de la voile qui est opposé au guidant. Cette voile est dite "triangulaire". Néanmoins, les bords de la voile ne sont pas rectilignes et le guindant est nettement convexe.- Figure 1 is a schematic side view of the front of a boat equipped with a device according to the invention; Figures 2 to 4 illustrate three embodiments of mounting means for a device according to the invention; and, Figure 5 illustrates another method of attachment for the hoist of a sail on the cable, in a system according to the invention. Figure 1 shows the front of a sailboat 1. This sailboat comprises a hull 2 and a mast 3. An asymmetrical front sail 4 is shown in use. One edge of the foremost sail, that is to say the leading edge, is called the luff 40. The sail 4 is held between three points, respectively a tack point 41, at the end. lower luff, a halyard point 42, at the high end of the guide, and a clew 43, at an angle of the sail which is opposite the guide. This sail is called "triangular". Nevertheless, the edges of the sail are not rectilinear and the hoist is clearly convex.
La voile est maintenue au voilier par un dispositif 6 selon l'invention, qui est prévu pour permettre l'enroulement de la voile 4 sur elle-même. Ce dispositif est relié d'une part au pont 20 du voilier, dans une zone du pont 20 proche de l'étrave 21 et distante du mât 3, et d'autre part à une partie supérieure 30 du mât 3.The sail is maintained in the sailboat by a device 6 according to the invention, which is provided to allow the winding of the sail 4 on itself. This device is connected on the one hand to the deck 20 of the sailboat, in an area of the deck 20 close to the bow 21 and distant from the mast 3, and on the other hand to an upper part 30 of the mast 3.
Le dispositif 6 comprend un câble 60 et à chaque extrémité 601 ,602 du câble, des moyens de montage 61-64. Il comprend en outre des moyens, ici un anneau 67, pour y fixer une drisse 7. La drisse permet la mise en tension du câble entre le pont 20 et le mât 3 lors des manœuvres d'enroulement ou de déroulement de la voile. En cours e navigation, la voile étant déroulée, la drisse permet de contrôler la déformation de la voile, c'est-à-dire son creux, donc son rendement.The device 6 comprises a cable 60 and at each end 601, 602 of the cable, mounting means 61-64. It further comprises means, here a ring 67, to attach a halyard 7. The halyard allows the tensioning of the cable between the bridge 20 and the mast 3 during winding or unwinding of the sail. During navigation, the sail being unwound, the halyard makes it possible to control the deformation of the sail, that is to say its hollow, thus its yield.

Ces moyens de montage sont des émerillons 61 ,62 prévus pour autoriser une rotation du câble 60 sur lui-même, c'est-à-dire sensiblement selon un axe longitudinal du câble 60, relativement à la coque 2 et au mât 3 considérées comme fixes.The mounting means comprise first mounting means 61 and second mounting means 62 for respectively fixing the device to the bridge 20 and the mast 3. These mounting means are swivels 61, 62 provided to allow rotation of the cable 60 on itself, that is to say substantially along a longitudinal axis of the cable 60, relative to the shell 2 and mast 3 considered fixed.
Les moyens de montage comprennent en outre des troisièmes moyens de montage 63 et des quatrièmes moyens de montage 64, pour monter respectivement à l'extrémité basse 601 et à l'extrémité haute 602 du câble 60. Ces moyens de montage sont des émerillons 63,64 prévus pour autoriser une rotation du câble 60 sur lui- même, c'est-à-dire sensiblement selon un axe longitudinal du câble 60, relativement à la voile 4. Dans l'exemple illustré, le troisième émerillon est disposé entre le câble et le premier émerillon, et le quatrième émerillon est disposé entre le câble et le deuxième émerillon.The mounting means further comprises third mounting means 63 and fourth mounting means 64, for mounting respectively at the lower end 601 and the upper end 602 of the cable 60. These mounting means are swivels 63, 64 provided to allow a rotation of the cable 60 on itself, that is to say substantially along a longitudinal axis of the cable 60, relative to the sail 4. In the illustrated example, the third swivel is disposed between the cable and the first swivel, and the fourth swivel is disposed between the cable and the second swivel.
Des moyens de liaison permettent de relier le point d'amure 41 avec une partie 631 du troisième émerillon 63, partie 631 qui est mobile autour de l'axe longitudinal du câble 60. Ces moyens sont ici un cordage 8 dont la longueur peut être réglée pour ajuster la tension relative de ce cordage 8 et du câble 60. Des moyens de liaison 8 similaires permettent de relier le point de drisse 42 avec une partie 641 du quatrième émerillon 64, partie 641 qui est mobile autour de l'axe longitudinal du câble 60. Des moyens 65 sont prévus pour entraîner le câble en rotation relativement au pont et au mât. Ces moyens d'entraînement sont illustrés à la figure 1 par des moyens de poulie 65. La poulie peut être entraînée manuellement, par exemple par l'intermédiaire d'un cordage de renvoi au cockpit, et/ou mécaniquement, par exemple par un moteur et/ou des moyens de ressort. La poulie 65 est montée solidaire en rotation avec une partie 613 commune aux premier et troisième émerillons 61 ,63, pièce qui est elle-même montée solidaire en rotation à l'extrémité basse 601 du câble 60.Connecting means make it possible to connect the tack point 41 with a portion 631 of the third swivel 63, part 631 which is movable about the longitudinal axis of the cable 60. These means are here a rope 8 whose length can be adjusted to adjust the relative tension of this rope 8 and the cable 60. Similar connecting means 8 make it possible to connect the halyard point 42 with a portion 641 of the fourth swivel 64, part 641 which is movable about the longitudinal axis of the cable 60. Means 65 are provided for driving the cable in rotation relative to the bridge and the mast. These drive means are illustrated in FIG. 1 by pulley means 65. The pulley can be driven manually, for example by means of a return rope to the cockpit, and / or mechanically, for example by an engine. and / or spring means. The pulley 65 is mounted to rotate with a portion 613 common to the first and third swivels 61, 63, which piece is itself mounted to rotate with the lower end 601 of the cable 60.
Une portion intermédiaire 44 du guidant 40 est fixée solidairement sur une portion intermédiaire correspondante 66 du câble 60. Dans la position d'usage de la voile 4 représentée à la figure 1 , on peut voir que de part et d'autre de la portion intermédiaire 44, le guindant comprend une portion libre 45,46, respectivement une portion libre basse 45 s'étendant depuis la portion intermédiaire 44 jusqu'à l'extrémité basse du guindant 40, et une portion libre haute 46 s'étendant depuis la portion intermédiaire 44 jusqu'à l'extrémité haute du guindant 40. Dans la position d'usage, chaque portion libre est progressivement plus éloignée du câble à mesure où l'on s'éloigne, sur cette portion libre, de la portion intermédiaire.An intermediate portion 44 of the guide 40 is fixed integrally on a corresponding intermediate portion 66 of the cable 60. In the position of use of the sail 4 shown in Figure 1, it can be seen that on either side of the intermediate portion 44, the luff comprises a free portion 45,46, respectively a low free portion 45 extending from the intermediate portion 44 to the lower end of the luff 40, and a high free portion 46 extending from the intermediate portion. 44 to the upper end of the hoist 40. In the use position, each free portion is progressively further away from the cable as one moves away on this free portion of the intermediate portion.
On va maintenant décrire l'enroulement de la voile 4 sur elle-même, et comment le dispositif 6 permet de surmonter les inconvénients que présentent les dispositifs de l'art antérieur. Pour préparer l'enroulement de la voile 4, il est préférable de tendre le câble de sorte qu'il prend une forme sensiblement rectiligne longitudinalement, tandis que la voile est choquée, de façon à exercer peu d'effort sur le câble, en limitant ainsi la déformation transversale.We will now describe the winding of the sail 4 on itself, and how the device 6 overcomes the disadvantages of the devices of the prior art. To prepare the winding of the sail 4, it is preferable to stretch the cable so that it takes a substantially rectilinear shape longitudinally, while the sail is shocked, so as to exert little effort on the cable, limiting thus the transverse deformation.
Lorsque le câble est ensuite mis en rotation grâce aux moyens d'entraînement 65, les portions intermédiaires correspondantes 44,66 du câble et la voile sont entraînées simultanément en rotation autour de l'axe longitudinal du câble tandis que les extrémités du guindant restent libres.When the cable is then rotated by the drive means 65, the corresponding intermediate portions 44,66 of the cable and the sail are driven simultaneously in rotation about the longitudinal axis of the cable while the ends of the luff remain free.
Lorsque le câble poursuit sa rotation, une zone de la voile d'abord proximale à la portion intermédiaire du guindant, commence à s'enrouler autour du câble. Les portions libres s'enroulent ensuite progressivement depuis la portion intermédiaire en allant vers les extrémités du guindant et avec elles les zones voisines de la voile.As the cable continues to rotate, a region of the sail first proximal to the intermediate portion of the luff, begins to wrap around the cable. The free portions then wind up progressively from the intermediate portion towards the ends of the luff and with them the neighboring areas of the sail.
L'enroulement complet du guindant permet d'absorber la partie de la voile qui, dans les dispositifs de l'art antérieur, provoquait la formation de plis et l'effet bouffant, alors que le dispositif 6 selon l'invention permet de réduire de façon très importante, voire de supprimer, ces effets indésirables. Une fois que le guindant et la partie correspondante de la voile sont complètement enroulés, l'enroulement de la partie restante de la voile ne pose pas de problème particulier et se poursuit comme si ce qui reste de la voile était un foc ou un génois, c'est-à-dire une voile avec un creux faible ou inexistant. Les figures 2 à 4 représentent les deuxièmes et quatrièmes moyens de montages. Des dispositions similaires, non représentées aux figures, peuvent être adoptées pour les premiers et troisièmes moyens de montage. Ces dispositions pouvant être choisies différentes entre elles pour chacune des extrémités du câble.The complete winding of the hoist makes it possible to absorb the part of the sail which, in the devices of the prior art, caused the formation of folds and the puffing effect, while the device 6 according to the invention makes it possible to reduce very important way, even to suppress, these undesirable effects. Once the luff and the corresponding part of the sail are completely wound, the winding of the remaining part of the sail does not pose any particular problem and continues as if what remains of the sail was a jib or a genoa, that is to say a sail with a weak or nonexistent hollow. Figures 2 to 4 show the second and fourth mounting means. Similar arrangements, not shown in the figures, may be adopted for the first and third mounting means. These arrangements can be chosen different from each other for each end of the cable.
Dans le mode de réalisation des figures 1 et 2, les deuxième émerillon 62 et quatrième émerillon 64 ne forment qu'une seule pièce. Cette pièce est constituée d'une première partie 624, reliée de façon solidaire en rotation avec le câble 60. La première partie 624 est similaire à la partie 613 du dispositif 6 illustré à la figure 1 , sur laquelle sont montés les moyens de poulie 65. La première partie 624 est montée sensiblement solidaire en rotation avec l'extrémité haute 602 du câble 60. Une deuxième partie 621 est montée en rotation dans la première partie 624, et forme avec la première partie le deuxième émerillon 62. Cette deuxième partie 621 porte l'anneau 67 qui permet d'attacher la drisse 7. Cette deuxième partie 621 permet en outre de désolidariser en rotation le câble et la drisse 7.In the embodiment of Figures 1 and 2, the second swivel 62 and fourth swivel 64 form a single piece. This part consists of a first portion 624, integrally connected in rotation with the cable 60. The first portion 624 is similar to the portion 613 of the device 6 shown in Figure 1, on which are mounted the pulley means 65 The first part 624 is mounted substantially integral in rotation with the upper end 602 of the cable 60. A second part 621 is rotatably mounted in the first part 624, and forms with the first part the second swivel 62. This second part 621 carries the ring 67 which makes it possible to attach the halyard 7. This second part 621 further makes it possible to detach the cable and the halyard 7 in rotation.
Une autre deuxième partie 641 est montée en rotation autour de la première partie 624, et forme avec la première partie le quatrième émerillon 64. Cette deuxième partie 641 porte un anneau qui permet d'attacher le cordage 8. Elle permet de désolidariser en rotation le câble et la voile 4.Another second part 641 is rotated around the first part 624, and forms with the first part the fourth swivel 64. This second part 641 carries a ring which makes it possible to fasten the rope 8. It makes it possible to detach in rotation the cable and sail 4.
Dans le mode de réalisation de la figure 3, les deuxième émerillon 62 et quatrième émerillon 64 sont deux pièces indépendantes. Chaque émerillon est constitué d'une première partie 620,640 respective. La première partie 640 du quatrième émerillon est montée sensiblement solidaire en rotation d'une part avec l'extrémité haute 602 du câble 60 et d'autre part avec la première partie 620 du deuxième émerillon 62.In the embodiment of Figure 3, the second swivel 62 and fourth swivel 64 are two independent parts. Each swivel consists of a respective first part 620,640. The first part 640 of fourth swivel is mounted substantially integral in rotation on the one hand with the upper end 602 of the cable 60 and on the other hand with the first part 620 of the second swivel 62.
La deuxième partie 621 du deuxième émerillon est ici montée en rotation dans la première partie 620, et forme avec la première partie 620 le deuxième émerillon 62.The second part 621 of the second swivel is here mounted in rotation in the first part 620, and forms with the first part 620 the second swivel 62.
La deuxième partie 641 du quatrième émerillon est ici montée en rotation autour de la première partie 620, et forme avec la première partie le quatrième émerillon 64.The second part 641 of the fourth swivel is here mounted in rotation around the first part 620, and forms with the first part the fourth swivel 64.
Le deuxième émerillon du mode de réalisation de la figure 4 est de conception identique à celui du mode de réalisation de la figure 3. Le quatrième en diffère en ce qu'il ne comporte pas de première partie spécifique. C'est le câble qui tient lieu de première partie pour le quatrième émerillon; la deuxième partie 641 étant directement montée en rotation autour du câble.The second swivel of the embodiment of FIG. 4 is of identical design to that of the embodiment of FIG. 3. The fourth differs in that it does not comprise a first specific part. It is the cable that takes the place of the first part for the fourth swivel; the second part 641 being directly mounted in rotation around the cable.
Dans le mode de réalisation illustré à la figure 1 , la portion intermédiaire 44 du guindant est fixée directement sur la partie intermédiaire correspondante 66 du câble 60. Dans le mode de réalisation de la figure 5, la partie intermédiaire 44 du guindant est indirectement fixée à la partie intermédiaire 66 du câble à l'aide d'un cordage 9 dont une première extrémité 91 est solidaire en rotation avec le câble. Ainsi, pour l'enroulement de la voile sur le câble, le cordage 9 est d'abord progressivement enroulé sur le câble. Lorsque ce cordage 9 est complètement enroulé, les portions intermédiaires correspondantes 44,66 du câble et la voile deviennent solidaires en rotation et, comme dans le mode de réalisation des la figure 1 , sont entraînées simultanément en rotation autour de l'axe longitudinal du câble tandis que les extrémités du guindant restent libres.In the embodiment illustrated in FIG. 1, the intermediate portion 44 of the luff is attached directly to the corresponding intermediate portion 66 of the cable 60. In the embodiment of FIG. 5, the intermediate portion 44 of the luff is indirectly fixed to the intermediate portion 66 of the cable using a rope 9, a first end 91 is integral in rotation with the cable. Thus, for the winding of the sail on the cable, the rope 9 is first gradually wound on the cable. When this rope 9 is completely wound, the corresponding intermediate portions 44,66 of the cable and the sail become integral in rotation and, as in the embodiment of Figure 1, are driven simultaneously in rotation about the longitudinal axis of the cable while the ends of the luff remain free.
Bien sûr, l'invention n'est pas limitée aux exemples qui viennent d'être décrits et de nombreux aménagements peuvent être apportés à ces exemples sans sortir du cadre de l'invention.Of course, the invention is not limited to the examples that have just been described and many adjustments can be made to these examples without departing from the scope of the invention.
Par exemple, la deuxième partie du quatrième émerillon peut être montée en rotation autour de la deuxième partie du deuxième émerillon.For example, the second part of the fourth swivel can be rotated around the second part of the second swivel.
La voile peut être fournie indépendamment du dispositif d'enroulement selon l'invention. Le dispositif peut alors comprendre des moyens pour fixer la portion intermédiaire d'une voile sur la portion correspondante du câble. Cette voile peut être une voile non spécifique du commerce, ou une voile spécifiquement adaptée pour être montée sur le dispositif.The sail can be provided independently of the winding device according to the invention. The device may then comprise means for fixing the intermediate portion of a sail on the corresponding portion of the cable. This sail can be a nonspecific sail of trade, or a sail specifically adapted to be mounted on the device.
La voile peut constituer avec le dispositif un système complet de voile d'avant, et être fournie avec le dispositif. Elle peut en outre ne former qu'une seule pièce avec le câble, le câble faisant partie intégrante de la voile. Dans un autre mode de réalisation, la voile peut être démontable du câble et comprendre les moyens pour la fixer sur le câble.The sail can constitute with the device a complete system of forward sail, and be provided with the device. It can also form one piece with the cable, the cable forming an integral part of the sail. In another embodiment, the sail may be removable from the cable and include means for securing it on the cable.
Les moyens d'entraînement peuvent être disposés différemment, par exemple comprendre une poulie montée solidaire avec le deuxième émerillon plutôt qu'avec le premier.The drive means may be arranged differently, for example comprise a pulley mounted integral with the second swivel rather than the first.
Le terme de cordage utilisé pour la liaison indirecte des portions intermédiaires du câble et du guidant, recouvrent aussi des moyens de liaison de type sangle. The term of rope used for the indirect connection of the intermediate portions of the cable and the guide, also cover strap type connection means.
