Abstract

Rigging for nautical or terrestrial craft comprising a sail (1) integral with a mast hinged to the craft. According to the invention, the sail (1) is stretched on two symmetrical uprights (2) which are themselves bent by a cable (7) tensioned by a hoist (10) so as to give the sail a lenticular shape.

Description

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 present invention relates to 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 «wishbone». 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 "wishbone". 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, widespread, gives satisfaction 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 viremement 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 erre suffisante pour permettre le viremement 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 above-mentioned rigging makes tacking downwind tricky because the sail is feathered during the jibe: at this point, the rider may end up in the water unless the board has enough wander to allow tacking.

Le brevet EP-A-0 031 074 (SCHLIEBS) décrit un gréement pour planche à voile monté sur un pied de mât articulé et comprenant un cadre fermé, à symétrie longitudinale sur lequel est établie la voile, un espar transversal de manoeuvre prenant appui de part et d'autre du cadre. La partie supérieure du cadre est arquée dans son plan alors que la partie inférieure, reposant sur le pied de mât, est constituée par un triangle.Patent EP-A-0 031 074 (SCHLIEBS) describes a rigging for windsurfing mounted on an articulated mast foot and comprising a closed frame, with longitudinal symmetry on which the sail is established, a transverse spar of maneuver taking support from on either side of the frame. The upper part of the frame is arched in its plane while the lower part, resting on the mast foot, consists of a triangle.

La présence du triangle formé par des branches inférieures empêche une déformation du cadre. Mais, étant donné qu'il n'existe pas de raidisseur en direction longitudinale, les montants du cadre doivent être épais et sont par suite lourds et peu aérodynamiques ce qui conduit à un mauvais rendement du gréement.The presence of the triangle formed by lower branches prevents deformation of the frame. However, since there is no stiffener in the longitudinal direction, the uprights of the frame must be thick and are consequently heavy and not very aerodynamic, which leads to poor rigging performance.

La présente invention a pour but de remédier aux inconvénients des gréement connus et de proposer un gréement présentant un rendement amélioré par rapport à ceux de la technique connue.The object of the present invention is to remedy the drawbacks of known rigging and to propose a rigging having an improved yield compared to those of the known technique.

Selon la présente invention, le gréement pour engin nautique ou terrestre, monté sur un pied de mât articulé et comprenant une voile établie sur un cadre fermé à axe de symétrie longitudinale dont l'extrémité supérieure est arquée dans au moins un plan, et un espar prenant appui sur le cadre, est caractérisé en ce que la voile au repos est taillée en forme de secteur d'ellipsoïde définissant une face concave et une face convexe, deux montants souples, arqués selon deux directions perpendiculaires, constituant le cadre et solidarisés avec la voile, étant réunis à leurs parties supérieure et inférieure, l'espar étant monté du côté de la face concave de la voile.According to the present invention, the rigging for nautical or land craft, mounted on an articulated mast foot and comprising a sail established on a closed frame with axis of longitudinal symmetry whose upper end is arched in at least one plane, and a spar bearing on the frame, is characterized in that the sail at rest is cut in the shape of an ellipsoid sector defining a concave face and a convex face, two flexible uprights, arched in two perpendicular directions, constituting the frame and secured to the sail, being joined at their upper and lower parts, the spar being mounted on the side of the concave face of the sail.

Selon une autre caractéristique de l'invention, le gréement est caractérisé en ce que les montants sont tendus par au moins un câble s'étendant sensiblement dans la direction longitudinale de la voile entre le point commun et la partie supérieure du gréement, au moins un moyen de tension étant disposé sur le câble.According to another characteristic of the invention, the rigging is characterized in that the uprights are stretched by at least one cable extending substantially in the longitudinal direction of the sail between the common point and the upper part of the rigging, at least one tension means being arranged on the cable.

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 de secteur d'ellipsoide, 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'un «quartier d'orange» sous-tendu par des arcs-boutants. On sait que cette structure est extrêmement résistante et le gréement ainsi constitué peut 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 cause the sail to take on the shape of an ellipsoid sector, 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 an "orange quarter" subtended by flying buttresses. We know that this structure is extremely resistant and the rigging thus formed can 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 bôme, d'une arcticula- tion. 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 boom, with an arcticula- tion. In case of difficulties, the rigging can bend thus avoiding breaking.

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 câble 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.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 a joint 16. The articulated mast foot 16 allows the rigging to move in all desired positions above the horizontal plane. It is known that the performance of a sail in the vicinity of the water surface is poor taking into account 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 stretched 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 avoid 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 a light metal alloy such as aluminum or of glass or carbon fibers included in a suitable resin.

Sur les Figs. 1 et 2, la voile présente une forme de secteur d'ellipsoide. 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 form of ellipsoid sector. 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 that 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 4 ends.

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) soir 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 car- guage 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 thanks to a sheath fitted with lacing means 31, either of the Velcro type (registered trademark) in the evening 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 sail mounting system and the geometrical structure of the sail make it very easy to obtain a reduction in the sail area by trapping 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 bôme 5 de forme arrondie permet de manoeuvrer le gréement, le câble 7 n'étant pas lié à la bôme ou espar 5. Le ou les câbles 7 passent à l'extérieur de la bôme 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 bôme 5 est fixée sur les montants 2 par des cordages.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 boom 5 of rounded shape allows the rigging to be maneuvered, the cable 7 not being linked to the boom or spar 5. The cable or cables 7 pass outside of the boom 5 so that the inclination of this allows to adjust the tension of the cable and consequently the hollow of the sail. The boom 5 is fixed to the uprights 2 by ropes.

Comme indiqué ci-dessus, la forme symétrique du gréement permet l'établissement d'une voile ou épaisse. Comme celà 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 de 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 celà apparaît à plus grande échelle sur la Fig. 7.As indicated above, the symmetrical shape of the rig allows the establishment of a sail or thick. As shown in Fig. 6, in the type of symmetrical rigging considered, the surface of 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 ply, the function of 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 this 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 soumis 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 écartement 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.When such a sail is subjected to the wind, the underside sheet 12 undergoes the pressure of the wind and takes a slightly marked curvature, while the face of the suction 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.

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 bôme 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 taré de retenue, jouant le rôle de frein. Comme celà apparaît sur la Fig. 8, le gréement peut se plier de la position I à la position Il 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 bôme 5 est également munie d'une articulation 29 de manière à permettre un pliage complet du gréement.The tensioned rigging according to the invention being slightly deformable is subjected to considerable forces in the breaking blades when it is not held by its user after falling into the water. In order to reduce the risk of the uprights 2 breaking, it is possible, as shown in FIG. 8, to provide them with an articulation 28 in the vicinity of the boom 5. Thus, the cable 7 collects the forces from the rear towards the front while the articulation bends in the opposite direction. 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 Il 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 reducing the size of the rigging at the height of the upper branch thereof, or substantially two thirds of the height of sailing. Preferably, the boom 5 is also provided with a hinge 29 so as to allow complete folding of the rigging.

La présente invention peut être mise en oeuvre chaque fois que l'on entend utiliser la force éolienne et notamment sur les voiliers, sur les planches à voile, sur les chariots à voile «speed- sails» (marque déposée) et sur les planches à roulettes (wind-skates).The present invention can be implemented whenever it is intended to use wind power and in particular on sailboats, on sailboards, on “speed-sails” (registered trademark) and on sailboards. casters (wind-skates).

2. Rigging according to claim 1, characterized in that the risers (2) are tensioned by at least one cable (7) extending substantially along the longitudinal direction of the sail (1) between the common point (4) and the top portion of the rigging, with at least one tensioning means (10) being disposed on the cable (7).
3. Rigging according to claim 1, characterized in that the risers (2) are interconnected by at least one transverse holding element (6, 8) fixed at its ends to the risers (2).
4. Rigging according to claim 2, characterized in that the cable (7) passes outside the spar (5) which is hinged to the risers (2).
5. Rigging according to any preceding claim, characterized in that the sail (1) is constituted by two sheets, respectively a convex sheet (11) and a concave sheet (12) with the ends of the sheets forming sheaths (14) for the risers (2).
6. Rigging according to claim 5, characterized in that a filling (13) is disposed between the two sheets (11,12).
7. Rigging according to any preceding claim, characterized in that the risers (2) are fitted with hinges (28) at substantially the same height as the spar (5) enabling the rigging to fold backwardly, the spar (5) having a hinge (29) in the middle portion thereof.
8. Rigging according to any preceding claim, characterized in that the sail (1) is threaded over the risers (2) and is held thereon by means (31 ) which are releasable from place to place to enable sail to be taken-in in horizontal strips (32).
