Description

GREEMENT, NOTAMMENT POUR PLANCHE A VOILE RIGGING, ESPECIALLY FOR SAILING BOARDS
La présente invention a pour objet un gréement destiné en particulier, mais non exclusivement aux planches à voile et notamment aux planches connues sous le nom de "fun-board".The subject of the present invention is a rigging intended in particular, but not exclusively for windsurfing boards and in particular for boards known under the name of "fun-board".
On sait que le gréement des planches à voile est actuellement réalisé au moyen d'une voile triangulaire enfilée sur un mât, lui-même monté au moyen d'une articulation sur la planche proprement dite. La manoeuvre de la voile s'effectue à l'aide d'une double bôme ou "whishbone". Un tel gréement est décrit dans le brevet US-A-3 487 800 au nom de SCHWEITZER.It is known that the rigging of windsurfers is currently carried out by means of a triangular sail threaded on a mast, itself mounted by means of a joint on the board itself. The sail is maneuvered using a double boom or "whishbone". Such rigging is described in US-A-3,487,800 in the name of SCHWEITZER.
Ce gréement, largement répandu, donne satisfaction en ce qui concerne les planches à voile traditionnelles, bien que son rendement ne soit pas parfait, notamment en raison du cintrage du mât sous l'action du vent qui fait que la voile déverse et perd de son efficacité.This rigging, widely used, is satisfactory with regard to traditional sailboards, although its performance is not perfect, in particular because of the bending of the mast under the action of the wind which causes the sail to dump and lose its efficiency.
On a vu récemment apparaître des planches dites "fun-board" qui sont plus petites que les précédentes et ne portent le planchiste que lorsque la planche est en mouvement ce qui conduit à des départs du genre ski nautique au cours desquels le planchiste est dans l'eau. Dans ce type de planche, l'utilisation du gréement mentionné ci-dessus rend délicat le virement de bord vent arrière car la voile se trouve en drapeau lors de l'empannage : à ce moment, le planchiste risque de se retrouver dans l'eau à moins que la planche n'ait une aire suffisante pour permettre le virement de bord.We recently saw the appearance of so-called "fun-boards" which are smaller than the previous ones and only carry the boarder when the board is in motion, which leads to departures of the water ski type during which the boarder is in the water. 'water. In this type of board, the use of the aforementioned rigging makes tacking downwind difficult because the sail is feathered during the jibe: at this moment, the rider may end up in the water unless the board has enough area to allow the tack.
La présente invention a pour objet de remédier à cet inconvénient en proposant un gréement de rendement amélioré par rapport à celui de la technique connue.The object of the present invention is to remedy this drawback by proposing improved performance rigging compared to that of the known technique.
Selon la présente invention, le gréement monté sur un pied de mât articulé est caractérisé en ce qu'il comprend une voile symétrique établie sur un cadre constitué de deux montants verticaux réunis à leurs parties supérieure et inférieure, la hauteur de la voile étant supérieure à sa largeur.According to the present invention, the rigging mounted on an articulated mast foot is characterized in that it comprises a symmetrical sail established on a frame consisting of two vertical uprights joined to their upper and lower parts, the height of the sail being greater than its width.
Selon une autre caractéristique de l'invention, le cadre précité est arqué par l'intermédiaire d'au moins un câble tendu entre le haut et le bas du gréement.According to another characteristic of the invention, the above-mentioned frame is arched by means of at least one cable stretched between the top and the bottom of the rigging.
Les montants sont arqués dans leur plan et dans un plan perpendiculaire à leur position de repos de manière à faire prendre à la voile une forme lenticulaire, un espar de manoeuvre ou bôme présentant une concavité opposée à celle de la voile tendue. Le gréement selon l'invention donne à la voile la forme d'une lentille sous-tendue par des arcs-boutants. On sait que cette structure est extrêmement résistante et le gréement ainsi constitué présente une bonne rigidité qui lui permet d'utiliser dans les meilleures conditions l'énergie du vent. De préférence, l' espar de manoeuvre est disposé entre les montants verticaux sensiblement au tiers de la hauteur de ceux-ci.The uprights are arched in their plane and in a plane perpendicular to their rest position so as to make the sail take a lenticular shape, an operating spar or boom having a concavity opposite to that of the taut sail. The rigging according to the invention gives the sail the form of a lens subtended by flying buttresses. We know that this structure is extremely resistant and the rigging thus formed has good rigidity which allows it to use the best wind energy. Preferably, the operating spar is disposed between the vertical uprights substantially at one third of the height thereof.
Selon encore une autre caractéristique de l' invention, chacun des montants constituant le mât est muni, à hauteur de la borne, d'une articulation. En cas de difficultés, le gréement peut plier évitant ainsi de casser.According to yet another characteristic of the invention, each of the uprights constituting the mast is provided, at the height of the terminal, with a hinge. In case of difficulties, the rigging can bend thus avoiding breaking.
D'autres caractéristiques et avantages de l'invention ressortiront de la description qui suit et qui, faite en référence aux dessins annexés, en illustre divers exemples de réalisation. Sur les dessins:Other characteristics and advantages of the invention will emerge from the description which follows and which, given with reference to the appended drawings, illustrates various embodiments thereof. In the drawings:

- La Fig.6, une vue en coupe horizontale d'une voile épaisse;- Fig.6, a horizontal sectional view of a thick sail;
- La Fig.7, un schéma montrant le montage d'une voile épaisse sur un montant;- Fig.7, a diagram showing the mounting of a thick sail on an amount;
- La Fig.8, un schéma montrant l'articulation des montants. Sur les Figs 1 et 2, la voile 1 est tendue sur des montants 2 reliés par leurs extrémités supérieure 3 et inférieure 4, l'extrémité inférieure 4 prenant appui sur la planche P au moyen d'une articulation 16. Le pied de mât articulé 16 permet au gréement de se mouvoir dans toutes les positions voulues au-dessus du plan horizontal. On sait que le rendement d'une voile au voisinage de la surface de l'eau est mauvais compte tenu de l'irrégularité des courants d'air à ce niveau. Une certaine constance dans la direction ne se retrouve que légèrement plus haut et selon une caractéristique de l'invention, la voile est en quelque sorte verticale, le rapport de sa hauteur sur sa largeur étant supérieur à celui d'une voile ordinaire. Ainsi, le rôle des courants d'air irréguliers de surface dans l'entraînement de la planche est réduit au minimum. Les montants 2 sont tendus par un ou des câbles 7 au moyen de tendeurs 10 (Fig.2) par exemple du type palan entre le pied de mât 16 et un espar horizontal 6 disposé au voisinage de la partie supérieure de la voile. Cette tension est appliquée sur les montants (2) avant adaptation du gréement sur la planche. En tant que de besoin, un ou deux câbles 8 ou espars 6 évitent une trop grande déformation de la voile sous l'influence de la traction exercée par les câbles 7. A hauteur d'homme, le gréement est tenu en main par le planchiste à l'aide de l'espar horizontal 5 qui est de préférence cintré en direction inverse de celle du cintrage de la voile . Ce gréement s'utilise comme un gréement classique pour progresser dans les différentes directions mais il facilite l'empannage de la voile puisque celle-ci étant symétrique, le planchiste le fait passer devant lui perpendiculairement à la direction du vent, et non dans le lit de celui-ci, ce qui inverse le bord d'attaque et le bord de fuite sur l'autre panne. Il n'y a donc plus de perte de puissance au moment de l'empannage, la voile n'ayant pas à être effacée en drapeau à aucun moment. En outre, la forme concave de la voile accroît sa puissance et son indéformabilité par les câbles verticaux qui contraignent les tubes à jouer le rôle d' arcs-boutants contrebalançant la traction du planchiste sur la bôme. Les montants 2 peuvent être réalisés par exemple en alliage de métaux légers tel que de l'aluminium ou en fibres de verre ou de carbone incluses dans une résine convenable.- Fig.8, a diagram showing the articulation of the uprights. In Figs 1 and 2, the sail 1 is stretched on uprights 2 connected by their upper 3 and lower 4 ends, the lower end 4 resting on the board P by means of an articulation 16. The articulated mast foot 16 allows the rig to move in any desired position above the horizontal plane. We know that the performance of a sail in the vicinity of the water surface is poor, given the irregularity of the air currents at this level. A certain consistency in the direction is found only slightly higher and according to a characteristic of the invention, the sail is somewhat vertical, the ratio of its height to its width being greater than that of an ordinary sail. Thus, the role of irregular surface air currents in driving the board is minimized. The uprights 2 are tensioned by one or more cables 7 by means of tensioners 10 (Fig. 2), for example of the hoist type between the mast foot 16 and a horizontal spar 6 disposed in the vicinity of the upper part of the sail. This tension is applied to the uprights (2) before adaptation of the rigging on the board. When necessary, one or two cables 8 or spars 6 prevent too much deformation of the sail under the influence of the traction exerted by the cables 7. At breast height, the rigging is held in hand by the boarder using the horizontal spar 5 which is preferably bent in the opposite direction to that of the bending of the sail. This rigging is used like a classic rigging to progress in the different directions but it facilitates the jibe of the sail since this one being symmetrical, the boarder makes it pass in front of him perpendicular to the direction of the wind, and not in the bed of it, which reverses the leading edge and the trailing edge on the other purlin. There is therefore no more loss of power during the jibe, the sail not having to be erased in flag at any time. In addition, the concave shape of the sail increases its power and its non-deformability by the vertical cables which force the tubes to play the role of flying buttresses counterbalancing the traction of the rider on the boom. The uprights 2 can be made for example of light metal alloy such as aluminum or fiberglass or carbon included in a suitable resin.
Sur les Figs 1 et 2, la voile présente une forme lenticulaire. Un câble 8 peut être monté entre les montants 2 de manière à ce que ceux-ci ne s'écartent pas exagérément dans un plan vertical au détriment du cintrage. Il est également possible d'utiliser un cadre tel que celui qui est représenté sur la Fig.3 dont la partie supérieure présente une surface de voile plus importante que la partie inférieure, les montants 2 étant réunis à nouveau à leurs extrémités supérieure 3 et inférieure 4.In Figs 1 and 2, the sail has a lenticular shape. A cable 8 can be mounted between the uprights 2 so that they do not deviate excessively in a vertical plane at the expense of bending. It is also possible to use a frame such as the one shown in Fig. 3, the upper part of which has a larger sail area than the lower part, the uprights 2 being brought together again at their upper 3 and lower ends. 4.
La Fig.4 représente le montage de la voile 1 sur un montant 2 grâce à un fourreau équipé de moyens de laçage 31 soit du type Velcro (marque déposée) soit par un système de boutonnage ou de fermeture à glissière. Des oeillets 27 montés de place en place sur la hauteur du montant 2 permettent de tendre la voile vers les extrémités du tube à l'aide d'un cordage non représenté. Ce système de montage de la voile ainsi que la structure géométrique de celle-ci permettent d'obtenir très aisément une réduction de voilure par carguage de la voile. Il suffit en effet de séparer la partie supérieure de la voile des montants 2 et de l'enrouler sur la hauteur désirée comme schématisé en 32 sur la Fig.1.Fig.4 shows the mounting of the sail 1 on an upright 2 using a sheath fitted with lacing means 31 either of the Velcro type (registered trademark) or by a buttoning or zipper system. Eyelets 27 mounted from place to place on the height of the upright 2 allow the sail to be stretched towards the ends of the tube using a rope not shown. This mounting system of the sail as well as the geometric structure of the latter make it possible to very easily obtain a reduction in sail by cargo loading of the sail. It suffices to separate the upper part of the sail from the uprights 2 and to wind it up to the desired height as shown diagrammatically at 32 in FIG. 1.
Sur la Fig.5, le gréement est constitué par une voile 1 établie sur deux montants symétriques 2 réunis à leurs extrémités supérieure 3 et inférieure 4, les montants 2 étant arc-boutés par un câble 7 tendu par un palan 10. Sensiblement au tiers de la hauteur de la voile, une borne 5 de forme arrondie permet de manoeuvrer le gréement, le câble 7 n'étant pas lié à la borne ou espar 5. Le ou les câbles 7 passent à l'extérieur de la borne 5 de sorte que l'inclinaison de celle-ci permet d'ajuster la tension du câble et par suite le creux de la voile. La borne 5 est fixée sur les montants 2 par des cordages. Comme indiqué ci-dessus, la forme symétrique du gréement permet l'établissement d'une voile pleine ou épaisse. Comme cela apparaît sur la Fig.6, dans le type de gréement symétrique considéré, la surface d'extrados 11 de la voile reste toujours la même, c'est à dire qu'à l'encontre de ce qui se produit dans une voile à une nappe classique, la fonction des faces de la voile n'est pas modifiée lors de l'utilisation. Ce gréement est donc particulièrement adapté pour recevoir une seconde nappe de tissu 12 destinée à constituer la surface d'intrados dont la conformation sera, au cours de l'utilisation, différente de celle de la surface d'extrados 11. De plus, la faible épaisseur du bord d'attaque constitué par l'un des montants 2, par rapport aux mâts classiques qui doivent pour contrebalancer les efforts qui leur sont appliqués par la voile être assez épais, favorise l'application des filets d'air sur les faces 11 et 12 d'une telle voile qui se comporte alors un peu comme une aile d'avion, sans trainée importante en arrière du bord de fuite. La voile selon une autre caractéristique de l'invention comprend deux nappes 11 et 12 de tissu réunies à leurs extrémités par deux fourreaux 14 dans lesquels sont inclus les montants 2, comme cela apparaît à plus grande échelle sur la Fig.7.In Fig.5, the rigging is constituted by a sail 1 established on two symmetrical uprights 2 joined at their upper 3 and lower 4 ends, the uprights 2 being braced by a cable 7 stretched by a hoist 10. Substantially one third of the height of the sail, a terminal 5 of rounded shape makes it possible to maneuver the rigging, the cable 7 not being linked to the terminal or spar 5. The cable or cables 7 pass outside the terminal 5 so that the inclination of the latter makes it possible to adjust the tension of the cable and consequently the hollow of the sail. Terminal 5 is fixed to the uprights 2 by ropes. As indicated above, the symmetrical shape of the rig allows the establishment of a full or thick sail. As shown in Fig. 6, in the type of symmetrical rigging considered, the upper surface 11 of the sail always remains the same, that is to say that contrary to what occurs in a sail with a conventional tablecloth, the function of the faces of the sail is not modified during use. This rigging is therefore particularly suitable for receiving a second sheet of fabric 12 intended to constitute the surface of the pressure surface, the conformation of which will be, during use, different from that of the surface of the pressure surface 11. In addition, the low thickness of the leading edge constituted by one of the uprights 2, compared to conventional masts which must, to counterbalance the forces applied to them by the sail, be fairly thick, favors the application of air streams on the faces 11 and 12 of such a sail which then behaves a bit like an airplane wing, without significant drag behind the trailing edge. The sail according to another characteristic of the invention comprises two sheets 11 and 12 of fabric joined at their ends by two sleeves 14 in which the uprights 2 are included, as appears on a larger scale in Fig.7.
Lorsqu'une telle voile est soumise au vent, la nappe d'intrados 12 subit la pression du vent et prend une courbure peu marquée, tandis que la face d'extrados 11 soumise à une dépression plus importante que la pression prend une courbure plus marquée, en relation avec l'écoulement des filets d'air sur la face 11. Afin d'améliorer le profil de la voile, il est possible d'introduire entre les nappes 11 et 12 une garniture 13 qui peut être , soit une couche de mousse plastique, soit encore un ensemble de lattes ou plus généralement tout matériau rigide ou semi-rigide maintenant un ecartement entre les deux nappes. Les nappes sont, par exemple cousues de manière à ce que les tensions sur chacune des nappes n'aient pas tendance à s'égaliser et qu'il n'y ait donc pas d'interactions entre les nappes. Le gréement tendu selon l'invention étant peu déformable est soumis à des efforts considérables dans les lames déferlantes lorsqu'il n'est pas tenu par son utilisateur après une chute à l'eau Afin de réduire les risques de rupture des montants 2, il est possible, comme représenté sur la Fig.8 de les munir d'une articulation 28 au voisinage de la borne 5. Ainsi, le câble 7 encaisse les efforts de l'arrière vers l'avant alors que l'articulation se plie dans le sens contraire. L'articulation 28 prévue sur chacun des montants est bien entendu bloquée par une pièce tarée de retenue, jouant le rôle de frein. Comme cela apparaît sur la Fig.8, le gréement peut se plier de la position I à la position II autour des articulations 28 lorsque les forces exercées sur le gréement sont trop importantes et correspondent au tarage du frein. Lorsque le frein est relâché, le pliage vers l'intérieur peut se faire librement permettant de réduire l'encombrement du gréement à la hauteur de la branche supérieure de celui-ci, soit sensiblement les deux tiers de la hauteur de la voile. De préférence, la borne 5 est également munie d'une articulation 29 de manière à permettre un pliage complet du gréement.When such a sail is subjected to the wind, the underside ply 12 is subjected to the pressure of the wind and takes a slightly marked curvature, while the upper face 11 subjected to a greater depression than the pressure takes a more marked curvature. , in relation to the flow of the air streams on the face 11. In order to improve the profile of the sail, it is possible to introduce between the layers 11 and 12 a lining 13 which may be either a layer of plastic foam, or even a set of slats or more generally any rigid or semi-rigid material maintaining a spacing between the two layers. The plies are, for example sewn so that the tensions on each of the plies do not tend to equalize and that there is therefore no interaction between the plies. Since the stretched rigging according to the invention is not very deformable, it is subjected to considerable efforts in the breaking blades when it is not held by its user after falling into the water. In order to reduce the risks of breaking the uprights 2, it is possible, as shown in Fig.8 to provide them with a hinge 28 in the vicinity of the terminal 5. Thus, the cable 7 collects the forces from the rear to the front while the articulation bends in the contrary. The articulation 28 provided on each of the uprights is of course blocked by a calibrated retaining piece, playing the role of brake. As shown in Fig.8, the rigging can bend from position I to position II around the joints 28 when the forces exerted on the rigging are too great and correspond to the setting of the brake. When the brake is released, the inward folding can be done freely to reduce the size of the rigging at the height of the upper branch thereof, or substantially two-thirds of the height of the sail.
