Description

DESCRIPTION DESCRIPTION
TITRE : Système de traction auto-orientable pour bateau TITLE: Self-orienting traction system for boats
Domaine de l'invention Field of the invention
La présente invention concerne un système de traction auto-orientable pour bateau. L'invention concerne également un voilier incluant le bateau et le système de traction auto-orientable. The present invention relates to a self-steering traction system for a boat. The invention also relates to a sailboat including the boat and the self-steering traction system.
Art antérieur Prior art
Il est connu de disposer d'un bateau qui peut être mis en mouvement par un système de traction monté directement sur le bateau. Le système de traction peut être un système à voile(s) comprenant notamment un mât et une voilure. It is known to have a boat which can be set in motion by a traction system mounted directly on the boat. The traction system can be a sail system(s) comprising in particular a mast and a sail.
Un voilier est défini comme l'ensemble comprenant un bateau et un système à voile(s) monté sur le bateau. A sailboat is defined as the assembly comprising a boat and a sail system(s) mounted on the boat.
Le bateau s'étend selon un axe longitudinal. La voilure est déviée par rapport à l'axe longitudinal pour naviguer dans diverses directions. The boat extends along a longitudinal axis. The sail is deflected from the longitudinal axis to navigate in various directions.
Toutefois, la poussée du vent qui est transversale à la voilure, engendre, en plus du déplacement du voilier, un couple de renversement latéral qui est responsable de la gite. However, the wind thrust which is transverse to the sail, generates, in addition to the movement of the sailboat, a lateral overturning torque which is responsible for the list.
Pour limiter la gite; divers dispositifs plus ou moins coûteux, lourds et complexes sont nécessaires : lest, quille profonde, déplacement d'équipage et de charges, foils, ou flotteurs latéraux. To limit listing; various more or less expensive, heavy and complex devices are necessary: ballast, deep keel, movement of crew and loads, foils, or lateral floats.
En outre, le skipper doit intervenir, pratiquement en continu, pour adapter l'incidence de la voilure aux fluctuations du vent dans le but de limiter la gite. Les virements de bord exigent des manœuvres délicates. Sur les voiliers multicoques, il faut également éviter le retournement qui est irrécupérable. In addition, the skipper must intervene, practically continuously, to adapt the incidence of the sail to wind fluctuations in order to limit listing. Tacking requires delicate maneuvers. On multihull sailboats, it is also necessary to avoid overturning which is irrecoverable.
La présente invention vise à résoudre tout ou partie des inconvénients mentionnés ci-dessus en limitant de manière simple et fiable la gite tout en facilitant le pilotage du voilier. The present invention aims to resolve all or part of the drawbacks mentioned above by limiting the list in a simple and reliable manner while facilitating the piloting of the sailboat.
Exposé de l'invention Presentation of the invention
A cet effet, la présente invention concerne un système de traction autoorientable pour un bateau, le système de traction auto-orientable comprenant : une voile, un mât configuré pour coopérer avec une partie supérieure de la voile, un assemblage flottant configuré pour coopérer avec le mât et une partie inférieure de la voile, un élément de liaison configuré pour relier l'assemblage flottant au bateau, l'élément de liaison comprenant une première extrémité configurée pour être montée mobile en rotation sur le bateau de sorte à permettre la rotation de l'assemblage flottant et de l'élément de liaison par rapport à un axe de référence du bateau, l'élément de liaison comprenant en outre une deuxième extrémité configurée pour coopérer avec l'assemblage flottant, un mécanisme de changement d'amure configuré pour déplacer et maintenir en position l'assemblage flottant par rapport à l'élément de liaison de sorte à modifier une position relative de l'assemblage flottant par rapport à l'axe de référence. To this end, the present invention relates to a self-steering traction system for a boat, the self-steering traction system comprising: a sail, a mast configured to cooperate with an upper part of the sail, a floating assembly configured to cooperate with the mast and a lower part of the sail, a connecting element configured to connect the floating assembly to the boat, the connecting element comprising a first end configured to be mounted movable in rotation on the boat so as to allow rotation of the floating assembly and the connecting element relative to a reference axis of the boat, the connecting element further comprising a second end configured to cooperate with the floating assembly, a tack changing mechanism configured to move and hold in position the floating assembly relative to the connecting element so as to modify a relative position of the floating assembly by relative to the reference axis.
Le système de traction auto-orientable comprend un assemblage flottant distinct du bateau. Le déplacement de l'assemblage flottant et donc de la voile est réalisé sans intervention de l'équipage du bateau. The self-steering traction system includes a floating assembly separate from the boat. The movement of the floating assembly and therefore of the sail is carried out without intervention by the boat's crew.
En effet, l'assemblage flottant sur lequel est montée la voile est libre en rotation par rapport à l'axe de référence et s'oriente librement pour maintenir constant l'angle d'incidence de la voile par rapport au vent relatif. In fact, the floating assembly on which the sail is mounted is free to rotate relative to the reference axis and is oriented freely to keep the angle of incidence of the sail relative to the relative wind constant.
Le mécanisme de changement d'amure est avantageux car il permet de régler la position de la voile par rapport à l'axe de référence sans déplacer la voile par rapport à l'assemblage flottant. A la place, l'assemblage flottant et la voile sont déplacés conjointement. The tack changing mechanism is advantageous because it allows the position of the sail to be adjusted relative to the reference axis without moving the sail relative to the floating assembly. Instead, the floating assembly and the sail are moved together.
Ceci facilite le changement de l'amure et le réglage de l'assiette. La fabrication du mécanisme de changement d'amure est également simple puisqu'il s'agit d'un mécanisme de maintien de la coopération permettant d'ajuster la position relative des deux parties coopérantes. This makes changing the tack and adjusting the trim easier. The manufacture of the tack change mechanism is also simple since it is a mechanism for maintaining cooperation making it possible to adjust the relative position of the two cooperating parts.
Par ailleurs, le système de traction auto-orientable engendre un équilibrage fondamentalement différent de celui des voiliers traditionnels et tire le bateau verticalement ce qui limite fortement le couple de renversement latéral responsable de la gite existant dans les voiliers traditionnels. Furthermore, the self-orienting traction system generates a balancing that is fundamentally different from that of traditional sailboats and pulls the boat vertically, which strongly limits the lateral overturning torque responsible for the list existing in traditional sailboats.
Le terme « traction » signifie que le système de traction auto-orientable est un système apte à permettre le déplacement du bateau, la voile entraînant ledit système et le bateau en réaction à la force du vent. Auto-orientable signifie que l'assemblage flottant est apte à se déplacer par rapport au bateau de façon à maintenir constant l'angle d'incidence de la voile avec le vent apparent. The term “traction” means that the self-orienting traction system is a system capable of allowing the movement of the boat, the sail driving said system and the boat reacting to the force of the wind. Self-orienting means that the floating assembly is able to move relative to the boat so as to maintain constant the angle of incidence of the sail with the apparent wind.
Selon un aspect de l'invention, l'assemblage flottant présente deux dispositifs d'attache fixes, chacun étant configuré pour coopérer avec un élément de fixation inférieur correspondant de la voile. According to one aspect of the invention, the floating assembly has two fixed attachment devices, each being configured to cooperate with a corresponding lower attachment element of the sail.
La partie inférieure de la voile est donc fixée en deux points fixes de l'assemblage flottant, ce qui simplifie le montage de la voile car il n'y a pas de dispositif de déplacement de la voile par rapport à l'assemblage flottant à prévoir. The lower part of the sail is therefore fixed at two fixed points of the floating assembly, which simplifies the assembly of the sail because there is no device for moving the sail relative to the floating assembly to be provided. .
Selon un exemple, chaque dispositif d'attache fixe présente une ouverture apte à recevoir l'élément de fixation inférieur de la voile. According to one example, each fixed attachment device has an opening capable of receiving the lower fixing element of the sail.
Selon un aspect de l'invention, le mât comprend un dispositif de fixation configuré pour coopérer avec un élément complémentaire la partie supérieure de la voile. La voile est ainsi solidaire de l'assemblage flottant par une fixation en trois points fixes les uns par rapport aux autres. According to one aspect of the invention, the mast comprises a fixing device configured to cooperate with an element complementary to the upper part of the sail. The sail is thus secured to the floating assembly by fixing it at three fixed points relative to each other.
Selon un aspect de l'invention, l'assemblage flottant comprend deux flotteurs montés de manière fixe l'un par rapport à l'autre, chaque flotteur comprenant un dispositif d'attache fixe correspondant. According to one aspect of the invention, the floating assembly comprises two floats fixedly mounted relative to each other, each float comprising a corresponding fixed attachment device.
Cette disposition permet d'alléger l'assemblage flottant et ainsi de faciliter le positionnement de la voile par rapport à la direction du vent. This arrangement makes it possible to lighten the floating assembly and thus facilitate the positioning of the sail in relation to the direction of the wind.
Selon un aspect de l'invention, l'assemblage flottant comprend une pièce centrale et deux montants latéraux, chaque montant latéral reliant la pièce centrale à un flotteur correspondant. According to one aspect of the invention, the floating assembly comprises a central part and two side uprights, each side upright connecting the central part to a corresponding float.
Cette organisation constitue une structure tétraédrique organisée autour de la pièce centrale dont les quatre sommets sont les extrémités du mât, des montants latéraux et de l'élément de liaison. This organization constitutes a tetrahedral structure organized around the central part whose four vertices are the ends of the mast, the side uprights and the connecting element.
Selon un aspect de l'invention, l'assemblage flottant est symétrique par rapport à un plan central passant par la pièce centrale et s'étendant transversalement à une droite reliant les deux flotteurs. According to one aspect of the invention, the floating assembly is symmetrical with respect to a central plane passing through the central part and extending transversely to a straight line connecting the two floats.
Ainsi, l'élément de liaison se situe soit d'un côté soit de l'autre du plan central, ce qui définit l'amure bâbord ou l'amure tribord lors de la navigation. La déviation maximale est de 15 degrés environ de chaque côté. Thus, the connecting element is located either on one side or the other of the central plane, which defines the port tack or the starboard tack during navigation. The maximum deviation is approximately 15 degrees on each side.
De préférence, un câble additionnel relie les deux flotteurs. Le câble additionnel est confondu avec la droite reliant les flotteurs. Selon un aspect de l'invention, chaque flotteur comprend un foil monté libre en rotation et configuré pour s'orienter en fonction des déplacements de l'assemblage flottant. Preferably, an additional cable connects the two floats. The additional cable coincides with the line connecting the floats. According to one aspect of the invention, each float comprises a foil mounted free to rotate and configured to orient itself according to the movements of the floating assembly.
Les foils disposés sous les flotteurs soulèvent l'assemblage flottant lorsque la vitesse est suffisante. Les foils des flotteurs sont munis d'un aileron et leur axe vertical tourne librement afin qu'ils s'orientent dans le courant. The foils placed under the floats lift the floating assembly when the speed is sufficient. The float foils are fitted with a fin and their vertical axis rotates freely so that they orient themselves in the current.
Selon un aspect de l'invention, le mât est monté sur la pièce centrale.According to one aspect of the invention, the mast is mounted on the central part.
La structure ainsi créée est légère et résistante. De préférence, l'assemblage flottant comprend deux haubans latéraux, chaque hauban latéral étant agencé pour relier le mât à l'extrémité du montant latéral correspondant. The structure thus created is light and resistant. Preferably, the floating assembly comprises two side shrouds, each side shroud being arranged to connect the mast to the end of the corresponding side upright.
Selon un aspect de l'invention, l'élément de liaison est un bras rectiligne, le bras rectiligne et la pièce centrale constituant une articulation pivotante. According to one aspect of the invention, the connecting element is a rectilinear arm, the rectilinear arm and the central part constituting a pivoting joint.
L'élément de liaison et l'assemblage flottant coopèrent selon un principe mécanique simple, ce qui facilite la fabrication et améliore la fiabilité du système de traction auto-orientable. The connecting element and the floating assembly cooperate according to a simple mechanical principle, which facilitates manufacturing and improves the reliability of the self-orienting traction system.
Selon un aspect de l'invention, le système de traction auto-orientable comprend un hauban arrière reliant le mât à la première extrémité de l'élément de liaison. De préférence, le hauban arrière inclut un tendeur configuré pour rigidifier la structure. According to one aspect of the invention, the self-orienting traction system comprises a rear stay connecting the mast to the first end of the connecting element. Preferably, the rear stay includes a tensioner configured to stiffen the structure.
Selon un aspect de l'invention, la pièce centrale est surélevée par rapport aux flotteurs. De préférence, la surélévation de la pièce centrale par rapport à la limite haute des flotteurs est inférieure à la longueur des montants latéraux et/ou de l'élément de liaison, et en particulier de l'ordre d'un quart de la moyenne des longueurs des montants latéraux et de l'élément de liaison. According to one aspect of the invention, the central part is raised relative to the floats. Preferably, the elevation of the central part relative to the upper limit of the floats is less than the length of the side uprights and/or the connecting element, and in particular of the order of a quarter of the average of the lengths of the side uprights and the connecting element.
Selon un aspect de l'invention, le mécanisme de changement d'amure comprend : au moins un câble de mise sous tension apte à relier l'assemblage flottant à l'élément de liaison, un agencement d'enroulement et de déroulement de l'au moins un câble de mise sous tension. According to one aspect of the invention, the tack changing mechanism comprises: at least one tensioning cable capable of connecting the floating assembly to the connecting element, a winding and unwinding arrangement of the at least one power cable.
Le mécanisme de changement d'amure peut ainsi maintenir l'orientation de l'assemblage flottant par rapport à l'élément de liaison tout en permettant la rotation conjointe de ces ceux éléments par rapport à l'axe de référence. The tack change mechanism can thus maintain the orientation of the floating assembly relative to the connecting element while allowing the joint rotation of these elements relative to the reference axis.
Le mécanisme de changement d'amure permet le déplacement relatif de l'assemblage flottant par rapport à l'élément de liaison tout en maintenant la coopération de ces derniers. Selon un aspect de l'invention, l'agencement d'enroulement et de déroulement est rapporté sur la première extrémité de l'élément de liaison et est centré selon l'axe de référence. The tack change mechanism allows the relative movement of the floating assembly relative to the connecting element while maintaining the cooperation of the latter. According to one aspect of the invention, the winding and unwinding arrangement is attached to the first end of the connecting element and is centered along the reference axis.
L'au moins un câble de mise sous tension s'enroule et se déroule autour de l'axe de référence. De préférence, l'agencement d'enroulement et de déroulement comprend un dispositif d'entrainement à vis sans fin permettant la rotation de l'au moins un câble de mise sous tension selon l'axe de référence. The at least one power-up cable is wound and unwound around the reference axis. Preferably, the winding and unwinding arrangement comprises a worm drive device allowing the rotation of the at least one tensioning cable along the reference axis.
En particulier, le dispositif d'entrainement à vis sans fin comprend un levier rotatif manuel. Cette disposition facilite l'enroulement et le déroulement. In particular, the worm drive device comprises a manual rotary lever. This arrangement makes rolling and unwinding easier.
Selon un aspect de l'invention, l'au moins un câble de mise sous tension correspond à un câble bâbord et un câble tribord montés à deux emplacements distincts de l'assemblage flottant, le câble bâbord s'enroulant autour de l'axe de référence lorsque le câble tribord se déroule et inversement. According to one aspect of the invention, the at least one power-up cable corresponds to a port side cable and a starboard cable mounted at two distinct locations of the floating assembly, the port side cable winding around the axis of reference when the starboard cable unwinds and vice versa.
L'assemblage flottant est maintenu par deux câbles, l'agencement d'enroulement et de déroulement permettant un enroulement et déroulement simultanés. Cet agencement d'enroulement et de déroulement est également appelé came d'empannage. The floating assembly is held by two cables, the winding and unwinding arrangement allowing simultaneous winding and unwinding. This furling and unwinding arrangement is also called a jibe cam.
Pour naviguer bâbord amure, l'assiette de la voile est ajustée en déviant l'élément de liaison dans le sens horaire. Au contraire, pour naviguer tribord amure, l'assiette est réglée en déviant l'élément de liaison dans le sens antihoraire. Cette déviation du bras arrière est réglée par les longueurs du câble bâbord et du câble tribord. To sail on port tack, the trim of the sail is adjusted by deflecting the connecting element clockwise. On the contrary, to sail starboard tack, the trim is adjusted by deflecting the connecting element counterclockwise. This deflection of the rear arm is regulated by the lengths of the port cable and the starboard cable.
L'agencement d'enroulement et de déroulement peut comprendre un dispositif classique destiné à afficher l'angle de rotation de l'assemblage flottant par rapport à l'élément de liaison et l'assiette de la voile. The furling and unwinding arrangement may include a conventional device for displaying the angle of rotation of the floating assembly relative to the connecting element and the trim of the sail.
Selon un aspect de l'invention, le câble bâbord et le câble tribord sont chacun configurés pour être fixés à un dispositif d'attache fixe correspondant ou un dispositif additionnel d'attache correspondant de l'assemblage flottant. According to one aspect of the invention, the port cable and the starboard cable are each configured to be attached to a corresponding fixed attachment device or a corresponding additional attachment device of the floating assembly.
Ainsi, les dispositifs d'attaches fixes peuvent ainsi être utilisés pour fixer à la fois, la voile, le câble bâbord et le câble tribord. Thus, the fixed attachment devices can be used to fix the sail, the port cable and the starboard cable at the same time.
Selon un aspect de l'invention, la deuxième extrémité de l'élément de liaison est configurée pour être montée mobile en rotation avec l'assemblage flottant selon un axe de réglage. According to one aspect of the invention, the second end of the connecting element is configured to be mounted movable in rotation with the floating assembly along an adjustment axis.
Le mécanisme de changement d'amure règle donc un angle entre l'élément de liaison et l'assemblage flottant. Selon un aspect de l'invention, le mécanisme de changement d'amure est configuré pour changer d'amure en une amure bâbord et en une amure tribord. Le mécanisme de changement d'amure permet également d'ajuster l'assiette. The tack changing mechanism therefore adjusts an angle between the connecting element and the floating assembly. According to one aspect of the invention, the tack changing mechanism is configured to change from tack to a tack port side and on a starboard tack. The tack change mechanism also allows you to adjust the trim.
Ainsi, l'assemblage flottant s'oriente sans intervention de l'équipage selon l'orientation du vent et le cap du navire, la seule intervention étant l'inversion du mécanisme de changement d'amure lors des virements de bords. Thus, the floating assembly is oriented without intervention from the crew according to the direction of the wind and the heading of the ship, the only intervention being the reversal of the tack change mechanism during tacks.
L'axe de réglage est distant de l'axe de référence. De préférence, l'axe de réglage est parallèle à l'axe de référence. Selon un aspect de l'invention, le mât s'étend parallèlement à l'axe de réglage ou selon l'axe de réglage. The adjustment axis is distant from the reference axis. Preferably, the adjustment axis is parallel to the reference axis. According to one aspect of the invention, the mast extends parallel to the adjustment axis or along the adjustment axis.
La présente invention concerne également un voilier comprenant un bateau et un système de traction auto-orientable tel que décrit ci-dessus apte à coopérer avec le bateau (3). The present invention also relates to a sailboat comprising a boat and a self-orienting traction system as described above capable of cooperating with the boat (3).
Selon un aspect de l'invention, le voilier comprend un gouvernail et une barre de contrôle du gouvernail, le mécanisme de changement d'amure étant monté sur l'axe de la barre de contrôle. According to one aspect of the invention, the sailboat comprises a rudder and a rudder control bar, the tack changing mechanism being mounted on the axis of the control bar.
Cette disposition permet de centraliser les commandes du voilier à un même emplacement. De préférence, la barre de contrôle s'étend selon l'axe de référence et comprend également une poignée. Selon un aspect de l'invention, le gouvernail inclut un foil. This arrangement allows the controls of the sailboat to be centralized in the same location. Preferably, the control bar extends along the reference axis and also includes a handle. According to one aspect of the invention, the rudder includes a foil.
Cet ensemble foil-gouvernail doit pouvoir supporter la charge verticale du bateau et la poussée latérale antidérive. This foil-rudder assembly must be able to support the vertical load of the boat and the anti-drift lateral thrust.
L'axe de la barre de contrôle est libre en rotation par rapport au mécanisme de changement d'amure pour conserver un contrôle indépendant du cap. The axis of the control bar is free to rotate relative to the tack change mechanism to maintain independent control of heading.
Selon un aspect de l'invention, le bateau présente une forme circulaire.According to one aspect of the invention, the boat has a circular shape.
Cette disposition permet de créer un voilier s'étendant selon une direction longitudinale. La direction longitudinale s'étend entre l'arrière défini par l'axe de référence et l'avant défini comme un point central entre les deux flotteurs. This arrangement makes it possible to create a sailboat extending in a longitudinal direction. The longitudinal direction extends between the rear defined by the reference axis and the front defined as a central point between the two floats.
La forme circulaire a pour centre l'axe de référence. The circular shape has the reference axis as its center.
Ce bateau ou flotteur principal de forme circulaire permet d'assurer la flottabilité à l'arrêt et à petite vitesse du voilier qui navigue sur son foil dès que la vitesse est suffisante. This circular-shaped boat or main float ensures buoyancy when stationary and at low speed of the sailboat which sails on its foil as soon as the speed is sufficient.
Durant la navigation, une force aérodynamique est appliquée vers l'avant suivant la direction longitudinale du voilier. Une résistance hydrodynamique, due à la traînée et à la composante antidérive est appliquée à l'arrière. En conséquence, la poussée du vent ne crée pas de gîte. Durant la navigation, la direction longitudinale du voilier s'oriente toujours à environ 95 degrés de la direction du vent, quelles que soient les variations du vent, le voilier se déplace latéralement (en crabe) vers le cap du gouvernail. During navigation, an aerodynamic force is applied forward following the longitudinal direction of the sailboat. Hydrodynamic resistance, due to drag and the anti-drift component, is applied to the rear. Consequently, the wind thrust does not create a list. During navigation, the longitudinal direction of the sailboat is always oriented at approximately 95 degrees from the direction of the wind, whatever the variations in the wind, the sailboat moves laterally (crab) towards the rudder heading.
Ces différences fondamentales d'équilibrage, comparativement à celles des voiliers classiques comprenant un mât monté sur le bateau, modifient radicalement le pilotage. Il n'y a pas à intervenir sur les voiles durant la navigation ni au changement de bord. Il n'est pas non plus nécessaire de déplacer charges et équipage sur le bateau au changement de bord. These fundamental differences in balancing, compared to those of classic sailboats comprising a mast mounted on the boat, radically modify the steering. There is no need to intervene on the sails during navigation or when changing sides. It is also not necessary to move loads and crew on the boat when changing sides.
La barre de contrôle commande l'orientation du gouvernail et du foil. Le déplacement vers le cap est déterminé, indépendamment de l'orientation du bateau, par le gouvernail (entre 35 et 180 degrés par rapport à la direction du vent réel). The control bar controls the orientation of the rudder and foil. The movement towards the heading is determined, independently of the orientation of the boat, by the rudder (between 35 and 180 degrees relative to the actual wind direction).
Les différents aspects définis ci-dessus non incompatibles peuvent être combinés. The different non-incompatible aspects defined above can be combined.

Description en référence aux figures Description with reference to the figures
Dans la description détaillée qui va suivre des figures définies ci-dessus, les mêmes éléments ou les éléments remplissant des fonctions identiques pourront conserver les mêmes références de manière à simplifier la compréhension de l'invention. In the detailed description which follows of the figures defined above, the same elements or elements fulfilling identical functions may retain the same references so as to simplify the understanding of the invention.
Comme illustré aux figures 1 à 3, un système de traction auto-orientable 1 pour un bateau 3 est présenté selon plusieurs points de vues. As illustrated in Figures 1 to 3, a self-orienting traction system 1 for a boat 3 is presented from several points of view.
Le système de traction auto-orientable 1 comprend une voile 5, un mât 7 configuré pour coopérer avec une partie supérieure 9 de la voile 5, un assemblage flottant 11 configuré pour coopérer avec le mât 7 et une partie inférieure 13 de la voile 5, et, un élément de liaison 15. The self-orienting traction system 1 comprises a sail 5, a mast 7 configured to cooperate with an upper part 9 of the sail 5, an assembly floating 11 configured to cooperate with the mast 7 and a lower part 13 of the sail 5, and a connecting element 15.
L'élément de liaison 15 est configuré pour relier l'assemblage flottant 11 au bateau 3. L'élément de liaison 15 comprend une première extrémité 17 configurée pour être montée mobile en rotation sur le bateau 3 de sorte à permettre la rotation l'assemblage flottant 11 et de l'élément de liaison 15 par rapport à un axe de référence 19 du bateau 3. The connecting element 15 is configured to connect the floating assembly 11 to the boat 3. The connecting element 15 comprises a first end 17 configured to be rotatably mounted on the boat 3 so as to allow the assembly to rotate floating 11 and the connecting element 15 relative to a reference axis 19 of the boat 3.
La position autour de l'axe de référence 19 est fonction de la direction du vent apparent 21 reçu par la voile 5, l'élément de liaison 15 comprenant en outre une deuxième extrémité 23 configurée pour coopérer avec l'assemblage flottant 11. The position around the reference axis 19 is a function of the direction of the apparent wind 21 received by the sail 5, the connecting element 15 further comprising a second end 23 configured to cooperate with the floating assembly 11.
Par ailleurs, le système de traction auto-orientable 1 comprend un mécanisme de changement d'amure 25 configuré pour déplacer et maintenir en position l'assemblage flottant 11 par rapport à l'élément de liaison 15 de sorte à modifier une position relative de l'assemblage flottant 11 par rapport à l'axe de référence 19. Furthermore, the self-orienting traction system 1 comprises a tack change mechanism 25 configured to move and maintain in position the floating assembly 11 relative to the connecting element 15 so as to modify a relative position of the floating assembly 11 relative to the reference axis 19.
L'assemblage flottant 11 est distinct du bateau 3. Le déplacement en rotation de l'assemblage flottant 11 et donc de la voile 5 autour de l'axe de référence 19 est réalisé sans intervention. The floating assembly 11 is distinct from the boat 3. The rotational movement of the floating assembly 11 and therefore of the sail 5 around the reference axis 19 is carried out without intervention.
En effet, l'assemblage flottant 11 sur lequel est montée la voile 5 est libre en rotation par rapport à l'axe de référence 19. La voile 5 s'oriente librement pour maintenir constant l'angle d'incidence par rapport à la direction du vent apparent 21. Indeed, the floating assembly 11 on which the sail 5 is mounted is free to rotate relative to the reference axis 19. The sail 5 orients freely to keep the angle of incidence constant with respect to the direction apparent wind 21.
L'assemblage flottant 11 présente deux dispositifs d'attache fixes Tl , chacun étant configuré pour coopérer avec un élément de fixation inférieur 29 correspondant de la voile 5. The floating assembly 11 has two fixed attachment devices Tl, each being configured to cooperate with a corresponding lower fixing element 29 of the sail 5.
La partie inférieure 13 de la voile 5 est donc fixée en deux points fixes de l'assemblage flottant 11, ce qui simplifie le montage de la voile 5 car il n'y a pas de dispositif de déplacement de la voile 5 par rapport à l'assemblage flottant 11 à prévoir. The lower part 13 of the sail 5 is therefore fixed at two fixed points of the floating assembly 11, which simplifies the assembly of the sail 5 because there is no device for moving the sail 5 relative to the sail 5. floating assembly 11 to be expected.
Ici, chaque dispositif d'attache fixe Tl présente une ouverture apte à recevoir l'élément de fixation inférieur 29 correspondant de la voile 5. Here, each fixed attachment device Tl has an opening capable of receiving the corresponding lower fixing element 29 of the sail 5.
Le mât 7 comprend un dispositif de fixation 31 configuré pour coopérer avec un élément complémentaire la partie supérieure 9 de la voile 5. La voile 5 est ainsi solidaire de l'assemblage flottant 11 par une fixation en trois points fixes les uns par rapport aux autres. The mast 7 comprises a fixing device 31 configured to cooperate with a complementary element the upper part 9 of the sail 5. The sail 5 is thus secured to the floating assembly 11 by a fixing at three fixed points relative to each other .
L'assemblage flottant 11 comprend deux flotteurs 33 montés de manière fixe l'un par rapport à l'autre, chaque flotteur 33 comprenant un dispositif d'attache fixe Tl correspondant. L'assemblage flottant 11 comprend une pièce centrale 35 et deux montants latéraux 37, chaque montant latéral 37 reliant la pièce centrale 35 à un flotteur 33 correspondant. The floating assembly 11 comprises two floats 33 fixedly mounted relative to each other, each float 33 comprising a corresponding fixed attachment device Tl. The floating assembly 11 comprises a central part 35 and two side uprights 37, each side upright 37 connecting the central part 35 to a corresponding float 33.
L'assemblage flottant 11 est symétrique par rapport à un plan central 39 passant par la pièce centrale 35 et s'étendant transversalement à une droite 41 reliant les deux flotteurs 33. The floating assembly 11 is symmetrical with respect to a central plane 39 passing through the central part 35 and extending transversely to a straight line 41 connecting the two floats 33.
L'élément de liaison 15 est un bras rectiligne, le bras rectiligne et la pièce centrale 35 constituant une articulation pivotante. The connecting element 15 is a rectilinear arm, the rectilinear arm and the central part 35 constituting a pivoting joint.
Ainsi, l'élément de liaison 15 se situe soit d'un côté soit de l'autre du plan central 39, ce qui définit l'amure bâbord ou l'amure tribord lors de la navigation. La déviation maximale est de 15 degrés environ de chaque côté. Thus, the connecting element 15 is located either on one side or the other of the central plane 39, which defines the port tack or the starboard tack during navigation. The maximum deviation is approximately 15 degrees on each side.
Un câble additionnel 43 relie les deux flotteurs 33. Le câble additionnel 43 est confondu avec la droite 41 reliant les flotteurs 33. An additional cable 43 connects the two floats 33. The additional cable 43 coincides with the line 41 connecting the floats 33.
Comme également visible à la figure 5, chaque flotteur 33 comprend un foil 45 monté libre en rotation et configuré pour s'orienter en fonction des déplacements de l'assemblage flottant 11. As also visible in Figure 5, each float 33 comprises a foil 45 mounted free to rotate and configured to orient itself according to the movements of the floating assembly 11.
Les foils 45 disposés sous les flotteurs 33 soulèvent l'assemblage flottant 11 lorsque la vitesse est suffisante. Les foils 45 des flotteurs 33 sont munis d'un aileron et leur axe vertical tourne librement afin qu'ils s'orientent dans le courant. The foils 45 arranged under the floats 33 lift the floating assembly 11 when the speed is sufficient. The foils 45 of the floats 33 are provided with a fin and their vertical axis rotates freely so that they orient themselves in the current.
Le mât 7 est monté sur la pièce centrale 35. L'assemblage flottant 11 comprend deux haubans latéraux 47, chaque hauban latéral 47 étant agencé pour relier le mât 7 à l'extrémité du montant latéral 37 correspondant. The mast 7 is mounted on the central part 35. The floating assembly 11 comprises two side stays 47, each side stay 47 being arranged to connect the mast 7 to the end of the corresponding side upright 37.
Le système de traction auto-orientable 1 comprend un hauban arrière 49 reliant le mât 7 à la première extrémité 17. Le hauban arrière 49 inclut un tendeur 51 configuré pour rigidifier la structure. The self-orienting traction system 1 includes a rear stay 49 connecting the mast 7 to the first end 17. The rear stay 49 includes a tensioner 51 configured to stiffen the structure.
La pièce centrale 35 est surélevée par rapport à la limite haute des flotteurs 33. La surélévation de la pièce centrale 35 par rapport aux flotteurs 33 est inférieure à la longueur des montants latéraux 37 et/ou de l'élément de liaison 15, et en particulier de l'ordre d'un quart de la moyenne des longueurs des montants latéraux 37 et de l'élément de liaison 15. The central part 35 is raised relative to the upper limit of the floats 33. The elevation of the central part 35 relative to the floats 33 is less than the length of the side uprights 37 and/or the connecting element 15, and in particularly of the order of a quarter of the average length of the side uprights 37 and the connecting element 15.
Comme également illustré à la figure 4, le mécanisme de changement d'amure 25 comprend au moins un câble de mise sous tension 53 apte à relier l'assemblage flottant 11 à l'élément de liaison 15, et, un agencement d'enroulement et de déroulement 55 de l'au moins un câble de mise sous tension 53. As also illustrated in Figure 4, the tack changing mechanism 25 comprises at least one tensioning cable 53 capable of connecting the floating assembly 11 to the connecting element 15, and, a winding arrangement and unwinding 55 of the at least one power-up cable 53.
Le mécanisme de changement d'amure 25 peut ainsi maintenir l'orientation de l'assemblage flottant 11 par rapport à l'élément de liaison 15 tout en permettant la rotation conjointe de ces ceux éléments par rapport à l'axe de référence 19. The tack change mechanism 25 can thus maintain the orientation of the floating assembly 11 relative to the connecting element 15 while allowing the joint rotation of these elements relative to the reference axis 19.
L'agencement d'enroulement et de déroulement 55 est rapporté sur la première extrémité 17 de l'élément de liaison 15 et est centré selon l'axe de référence 19. The winding and unwinding arrangement 55 is attached to the first end 17 of the connecting element 15 and is centered along the reference axis 19.
L'au moins un câble de mise sous tension 53 s'enroule et se déroule autour de l'axe de référence 19. L'agencement d'enroulement et de déroulement 55 comprend un dispositif d'entrainement à vis sans fin 57 permettant la rotation de l'au moins un câble de mise sous tension 53 selon l'axe de référence 19. Le dispositif d'entrainement à vis sans fin 57 comprend un levier rotatif manuel 59. The at least one tensioning cable 53 winds and unwinds around the reference axis 19. The winding and unwinding arrangement 55 comprises a worm drive device 57 allowing rotation of the at least one tensioning cable 53 along the reference axis 19. The worm drive device 57 comprises a manual rotary lever 59.
Ici, l'au moins un câble de mise sous tension 53 correspond à un câble bâbord 61 et un câble tribord 63 montés à deux emplacements distincts de l'assemblage flottant 11, le câble bâbord 61 s'enroulant autour de l'axe de référence 19 lorsque le câble tribord 63 se déroule et inversement. Here, the at least one power-up cable 53 corresponds to a port side cable 61 and a starboard cable 63 mounted at two distinct locations of the floating assembly 11, the port side cable 61 winding around the reference axis 19 when the starboard cable 63 unwinds and vice versa.
L'assemblage flottant 11 est maintenu par deux câbles, l'agencement d'enroulement et de déroulement 55 permettant un enroulement et déroulement simultanés. Cet agencement d'enroulement et de déroulement 55 est également appelé came d'empannage. The floating assembly 11 is held by two cables, the winding and unwinding arrangement 55 allowing simultaneous winding and unwinding. This winding and unwinding arrangement 55 is also called a jibe cam.
Comme illustré à la figure 2, pour naviguer bâbord amure, l'assiette de la voile 5 est ajustée en déviant l'élément de liaison 15 dans le sens horaire. Au contraire, pour naviguer tribord amure, l'assiette est réglée en déviant l'élément de liaison dans le sens antihoraire. L'axe 39 est l'axe de symétrie, les axes 65 et 75 correspondant respectivement à la position de l'élément de liaison tribord amure et bâbord amure. Cette déviation du bras arrière est réglée par les longueurs du câble bâbord 61 et du câble tribord 63. As illustrated in Figure 2, to sail on port tack, the trim of the sail 5 is adjusted by deflecting the connecting element 15 clockwise. On the contrary, to sail starboard tack, the trim is adjusted by deflecting the connecting element counterclockwise. Axis 39 is the axis of symmetry, axes 65 and 75 corresponding respectively to the position of the starboard tack and port tack connecting element. This deviation of the rear arm is adjusted by the lengths of the port cable 61 and the starboard cable 63.
L'agencement d'enroulement et de déroulement 55 peut comprendre un dispositif classique destiné à afficher l'angle de rotation de l'assemblage flottant 11 par rapport à l'élément de liaison 15 et l'assiette de la voile. The furling and unwinding arrangement 55 may include a conventional device intended to display the angle of rotation of the floating assembly 11 relative to the connecting element 15 and the trim of the sail.
Le câble bâbord 61 et le câble tribord 63 sont chacun configurés pour être fixés à un dispositif d'attache fixe Tl correspondant de l'assemblage flottant 11. The port cable 61 and the starboard cable 63 are each configured to be attached to a corresponding fixed attachment device Tl of the floating assembly 11.
La deuxième extrémité 23 de l'élément de liaison 15 est configurée pour être montée mobile en rotation avec l'assemblage flottant 11 selon un axe de réglage 67. The second end 23 of the connecting element 15 is configured to be mounted movable in rotation with the floating assembly 11 along an adjustment axis 67.
Le mécanisme de changement d'amure 25 règle donc un angle entre l'élément de liaison 15 et l'assemblage flottant 11. Le mécanisme de changement d'amure 25 est configuré pour changer d'amure en une amure bâbord et en une amure tribord. Le mécanisme de changement d'amure 25 permet également d'ajuster l'assiette. The tack changing mechanism 25 therefore adjusts an angle between the connecting element 15 and the floating assembly 11. The tack changing mechanism 25 is configured to change the tack into a port tack and a port tack. starboard. The tack change mechanism 25 also makes it possible to adjust the trim.
Ainsi, l'assemblage flottant s'oriente sans intervention de l'équipage selon l'orientation du vent et le cap du navire, la seule intervention étant l'inversion du mécanisme de changement d'amure lors des virements de bords. Thus, the floating assembly is oriented without intervention from the crew according to the direction of the wind and the heading of the ship, the only intervention being the reversal of the tack change mechanism during tacks.
L'axe de réglage 67 est distant de l'axe de référence 19. L'axe de réglage 67 est parallèle à l'axe de référence 19. Dans le mode de réalisation présenté, le mât 7 s'étend selon l'axe de réglage 67. The adjustment axis 67 is distant from the reference axis 19. The adjustment axis 67 is parallel to the reference axis 19. In the embodiment presented, the mast 7 extends along the axis of setting 67.
Le bateau 3 et le système de traction auto-orientable 1 constituent ainsi un voilier 69 lorsqu'ils coopèrent. Le voilier 69 comprend un gouvernail 71 et une barre de contrôle 73 du gouvernail 71, le mécanisme de changement d'amure 25 étant monté sur l'axe de la barre de contrôle 73, l'axe étant libre en rotation par rapport au mécanisme de changement d'amure 25 pour conserver un contrôle indépendant du cap. The boat 3 and the self-steering traction system 1 thus constitute a sailboat 69 when they cooperate. The sailboat 69 comprises a rudder 71 and a control bar 73 of the rudder 71, the tack change mechanism 25 being mounted on the axis of the control bar 73, the axis being free to rotate relative to the tack mechanism. change of tack 25 to maintain independent control of course.
Cette disposition permet de centraliser les commandes du voilier 69 à un même emplacement. La barre de contrôle 73 s'étend selon l'axe de référence 19 et comprend également une poignée. This arrangement makes it possible to centralize the controls of the sailboat 69 in the same location. The control bar 73 extends along the reference axis 19 and also includes a handle.
Comme visible à la figure 4, le gouvernail 71 inclut un foil 45. Cet ensemble foil-gouvernail 71 supporte la charge verticale du bateau 3 et la poussée latérale antidérive. As visible in Figure 4, the rudder 71 includes a foil 45. This foil-rudder assembly 71 supports the vertical load of the boat 3 and the anti-drift lateral thrust.
Le bateau 3 présente une forme circulaire. Comme illustré à la figure 2, cette disposition permet de créer un voilier 69 s'étendant selon une direction longitudinale 75. La direction longitudinale 75 s'étend entre l'arrière défini par l'axe de référence 19 et l'avant défini comme un point central entre les deux flotteurs 33. La forme circulaire a pour centre l'axe de référence 19. Boat 3 has a circular shape. As illustrated in Figure 2, this arrangement makes it possible to create a sailboat 69 extending in a longitudinal direction 75. The longitudinal direction 75 extends between the rear defined by the reference axis 19 and the front defined as a central point between the two floats 33. The circular shape has the reference axis 19 as its center.
L'assiette réglable par le mécanisme de changement d'amure 25 correspond à l'angle entre la perpendiculaire à la direction longitudinale 75 et la droite 41 reliant les deux flotteurs 33 sur bâbord amure, et à l'angle entre la perpendiculaire à la direction longitudinale 65 et la droite 41 reliant les deux flotteurs 33 sur tribord amure. The trim adjustable by the tack change mechanism 25 corresponds to the angle between the perpendicular to the longitudinal direction 75 and the straight line 41 connecting the two floats 33 on the port tack, and to the angle between the perpendicular to the direction longitudinal 65 and the straight 41 connecting the two floats 33 on the starboard tack.
Durant la navigation bâbord amure conformément à la figure 2, une force aérodynamique 77 est appliquée vers l'avant suivant la direction longitudinale 75 du voilier 69. Une résistance hydrodynamique 79, due à la traînée et à la composante antidérive est appliquée à l'arrière. En conséquence, la poussée du vent ne crée pas de gite. Durant la navigation, quelles que soient les variations du vent, le voilier 69 se déplace latéralement (en crabe) vers un cap 81 du gouvernail 71. During port tack navigation in accordance with Figure 2, an aerodynamic force 77 is applied forward in the longitudinal direction 75 of the sailboat 69. A hydrodynamic resistance 79, due to drag and the anti-drift component, is applied to the rear . Consequently, the wind thrust does not create a list. During navigation, whatever the variations in the wind, the sailboat 69 moves laterally (like a crab) towards a heading 81 of the rudder 71.
A la figure 2, la direction du vent 21 est représenté venant du haut, le voilier 69 naviguant bâbord amure. Dans ces conditions la force aérodynamique 77 oriente le voilier 69 à environ 95 degrés du vent vers tribord, tandis que la résultante hydrodynamique 79 lui est opposée en sens inverse. Sur cette amure bâbord, le déplacement vers le cap 81 peut être choisi entre 35 degrés et 180 degrés du vent réel vers tribord. Sur tribord amure, le déplacement peut être choisi entre 35 et 180 degrés du vent réel vers bâbord. In Figure 2, the direction of the wind 21 is shown coming from above, the sailboat 69 sailing on port tack. Under these conditions the aerodynamic force 77 orients the sailboat 69 at approximately 95 degrees from the wind to starboard, while the hydrodynamic resultant 79 is opposed to it in the opposite direction. On this port tack, the movement towards heading 81 can be chosen between 35 degrees and 180 degrees from the true wind to starboard. On starboard tack, the shift can be chosen between 35 and 180 degrees from the true wind to port.
Ces différences fondamentales d'équilibrage, comparativement à celles des voiliers classiques comprenant un mât monté sur le bateau, modifient radicalement le pilotage. Il n'y a pas à intervenir sur les voiles durant la navigation ni au changement de bord. Il n'est pas non plus nécessaire de déplacer charges et équipage sur le bateau au changement de bord. These fundamental differences in balancing, compared to those of classic sailboats comprising a mast mounted on the boat, radically modify the steering. There is no need to intervene on the sails during navigation or when changing sides. It is also not necessary to move loads and crew on the boat when changing sides.
Par ailleurs, le mécanisme de changement d'amure 25 est avantageux car il permet de régler la position de la voile 5 par rapport à l'axe de référence 19 sans déplacer la voile 5 par rapport à l'assemblage flottant 11. A la place, l'assemblage flottant 11 et la voile 5 sont déplacés conjointement. Furthermore, the tack changing mechanism 25 is advantageous because it makes it possible to adjust the position of the sail 5 relative to the reference axis 19 without moving the sail 5 relative to the floating assembly 11. Instead , the floating assembly 11 and the sail 5 are moved together.
Ceci facilite changement de l'amure et le réglage de l'assiette. La fabrication du mécanisme de changement d'amure 25 est également simple puisqu'il s'agit d'un mécanisme de maintien de la coopération permettant d'ajuster la position relative des deux parties coopérantes. This makes it easier to change the tack and adjust the trim. The manufacture of the tack change mechanism 25 is also simple since it is a mechanism for maintaining cooperation making it possible to adjust the relative position of the two cooperating parts.
Comme il va de soi, l'invention ne se limite pas à la seule forme d'exécution décrite ci-dessus à titre d'exemple, elle en embrasse au contraire toutes les variantes de réalisation et peut s'étendre à d'autres supports, sol dur, neige ou glace, en remplaçant le bateau et les flotteurs par des roues, ski ou patins. As it goes without saying, the invention is not limited to the sole form of execution described above by way of example, on the contrary it embraces all the variant embodiments and can extend to other supports. , hard ground, snow or ice, replacing the boat and floats with wheels, skis or skates.
