Abstract

The system has a rigid sail segmented horizontally into sail segments (21), where progression of pivoting of all the segments is ensured by a double reduction/increase system of a sail surface. The sail segments rotates in a horizontal plane around an axis located in its medium (22) so as to provide a surface (23) when the segments are active or a section (24) when the segments are inactive. Each segment has a pair of pulleys, where one of the pulleys is traversed by a rotation axis of the segment and another pulley is positioned in bottom of the segment.

Description

-1- La présente invention concerne un système de réduction/augmentation progressive de la surface d'une voile rigide. Les voiles rigides ou « ailes » actuellement utilisées sur les voiliers de dernière génération ont pour défaut majeur de ne pouvoir être « affalées », c'est-à-dire de pouvoir réduire leur surface au vent, comme pour une voile en tissus traditionnelle. La seule solution actuellement envisagée consiste en leur démontage pur et simple et ne peut s'effectuer qu'une fois rentré au port. Le dispositif selon l'invention permet de remédier à cet inconvénient. Le système consiste en la segmentation horizontale de la voile, chaque segment représentant une hauteur de « ris », soit une réduction/augmentation de surface de voilure potentielle, la réduction progressant, segment par segment, du haut vers le bas et l'augmentation en sens inverse. La réduction effective de la surface au vent s'effectue par rotation du segment dans le plan horizontal, autour d'un axe situé en son milieu, afin de n'offrir au vent que la section du segment de voile. L'augmentation, utilisant le processus inverse. Les dessins annexés illustrent l'invention : La figure 1 représente une vue d'ensemble du dispositif monté sur un voilier.The present invention relates to a progressive reduction / increase system of the surface of a rigid sail. The rigid sails or "wings" currently used on the latest generation sailboats have the major drawback of not being able to be "slumped", that is to say to be able to reduce their surface to the wind, as for a traditional fabric sail. The only solution currently envisaged is to dismantle them outright and can only be done once returned to port. The device according to the invention overcomes this disadvantage. The system consists of the horizontal segmentation of the sail, each segment representing a height of "reef", ie a reduction / increase of potential sail area, the progressive reduction, segment by segment, from top to bottom and the increase in reverse. The effective reduction of the wind surface is effected by rotation of the segment in the horizontal plane, around an axis located in the middle, in order to offer the wind only the section of the sail segment. The increase, using the reverse process. The accompanying drawings illustrate the invention: FIG. 1 represents an overall view of the device mounted on a sailboat.

La figure 2 détaille le fonctionnement de réduction/augmentation de la surface au vent d'un segment. La figure 3 représente les systèmes de réduction et d'augmentation de la surface de la voile. Les figures 3A-R et 3A-A représentent la cinématique des systèmes de réduction/augmentation. En référence à ces dessins, le dispositif est décrit selon deux composantes interdépendantes : Le système de réduction/augmentation de surface au vent d'un segment Les systèmes de réduction/augmentation progressive de la surface au vent de la voile -2- Système de réduction/augmentation de surface au vent d'un segment (FIG. 2) Partant du principe que « affaler » une voile consiste à réduire la surface exposée au vent, le système de réduction par segment consiste, non pas à supprimer de la surface, comme sur une voile traditionnelle, mais d'en modifier l'orientation pour la rendre inopérante. Pour ce faire, chaque segment de voile (21) va pouvoir effectuer une rotation dans le plan horizontal, autour d'un axe situé en son milieu (22), de manière à présenter au vent, non pas sa surface (23), mais sa section (24), sur laquelle, le vent n'aura pas plus de prise que sur un élément de gréement traditionnel (mât, bôme...). L'augmentation de surface s'appuie sur le processus inverse pour un segment réduit.Figure 2 details the operation of reducing / increasing the wind area of a segment. Figure 3 shows the systems for reducing and increasing the surface of the sail. Figures 3A-R and 3A-A show the kinematics of the reduction / augmentation systems. With reference to these drawings, the device is described according to two interdependent components: The wind surface reduction / augmentation system of a segment The progressive reduction / increase systems of the wind surface of the sail -2- Reduction system / Wind surface augmentation of a segment (FIG 2) Assuming that "slackening" a sail is to reduce the area exposed to the wind, the segment reduction system consists, not to remove from the surface, as on a traditional sail, but to change the orientation to make it inoperative. To do this, each sail segment (21) will be able to rotate in the horizontal plane, about an axis located in its middle (22), so as to present the wind, not its surface (23), but its section (24), on which, the wind will have no more hold than on a traditional rigging element (mast, boom ...). The surface increase is based on the reverse process for a reduced segment.

Systèmes de réduction/augmentation progressive de la surface au vent de la voile (FIG. 3) Afin de maîtriser la surface de voile à réduire et permettre une réduction progressive du haut vers le bas comme pour une voile traditionnelle, chaque segment de voile (21) est doté d'une paire de poulies, l'une traversée par l'axe de rotation du segment (31R), l'autre positionnée en bas de segment (32R). Chaque segment possède également une contrainte (33R), arrêtant la rotation lorsque le segment est en position horizontale. Les poulies de réduction des différents segments sont reliées les unes aux autres par un « bout » (corde) selon un enroulement précis (34R). Une traction sur ce « bout » permet la réduction progressive de la voile, par le pivotement successif de chaque segment du haut vers le bas (FIG.Progressive reduction / increase systems of the wind surface of the sail (FIG 3) In order to control the sail area to reduce and allow a progressive reduction from top to bottom as for a traditional sail, each sail segment (21) ) is provided with a pair of pulleys, one traversed by the axis of rotation of the segment (31R), the other positioned at the bottom of the segment (32R). Each segment also has a constraint (33R), stopping the rotation when the segment is in a horizontal position. The reduction pulleys of the different segments are connected to each other by a "tip" (rope) according to a precise winding (34R). A pull on this "end" allows the progressive reduction of the sail, by the successive pivoting of each segment from top to bottom (FIG.

3A-R). De même, pour l'augmentation progressive de la voile réduite, chaque segment de voile est doté d'une paire de poulies, l'une traversée par l'axe de rotation du segment (31A), l'autre positionnée en bas de segment (32A). Chaque segment possède également une contrainte (33A), arrêtant la rotation lorsque le segment est en position verticale, dans le plan de la voile. Les poulies d'augmentation des différents segments sont reliées les unes aux autres par un « bout » (corde) selon un enroulement précis (34A). Une traction sur ce « bout » permet l'augmentation progressive de la voile réduite, par le pivotement successif de chaque segment du bas vers le haut (FIG.3A-Rs). Similarly, for the progressive increase of the reduced sail, each sail segment is provided with a pair of pulleys, one traversed by the axis of rotation of the segment (31A), the other positioned at the bottom of the segment. (32A). Each segment also has a constraint (33A), stopping the rotation when the segment is in a vertical position, in the plane of the sail. The increase pulleys of the different segments are connected to each other by a "tip" (rope) according to a precise winding (34A). Pulling on this "tip" allows the gradual increase of the reduced sail, by successive pivoting of each segment from bottom to top (FIG.

3A-A). Le dispositif selon l'invention permet de faire varier la surface au vent d'une voile rigide, la rendant plus souple d'utilisation en mer et offrant la possibilité d'un « mouillage » (arrêt), intra ou extra portuaire sans démontage de la voile, Il devrait donc, de fait, permettre de démocratiser l'utilisation de la voile rigide et la faire sortir du seul registre de la haute compétition pour la faire entrer dans des domaines aussi variés que la plaisance ou le transport maritime.3A-A). The device according to the invention makes it possible to vary the windward surface of a rigid sail, making it more flexible to use at sea and offering the possibility of "wetting" (stop), intra or extra port without dismantling of It should therefore, in fact, make it possible to democratize the use of rigid sailing and remove it from the only register of high competition to enter fields as varied as pleasure craft or maritime transport.
