Description

La présente invention a trait à un dispositif de réduction de voilure, plus précisément la grand-voile d'un voilier, par enroulement de cette dernière sur la bôme et plus particulièrement encore une bôme dite à enrouleur.The present invention relates to a device for reducing the sail area, more precisely the mainsail of a sailboat, by winding the latter on the boom and more particularly still a so-called furling boom.

Ce type de bôme est bien connu et permet de réduire la grand-voile verticalement en l'enroulant autour d'une gaine montée pivotante à l'intérieur même de la bôme, l'entraînement en rotation de ladite gaine étant réalisé soit par un tambour intérieur, soit par un moteur hydraulique ou électrique.This type of boom is well known and makes it possible to reduce the mainsail vertically by wrapping it around a sheath pivotally mounted inside the boom itself, the rotary drive of said sheath being carried out either by a drum. interior, either by a hydraulic or electric motor.

Ce système donne cependant des résultats médiocres car il est utilisé avec un dispositif de guidage de la ralingue du guindant de voile constitué par une gorge verticale fixée à l'arrière du mât.However, this system gives poor results because it is used with a device for guiding the headline of the sail luff constituted by a vertical groove fixed to the rear of the mast.

Un tel dispositif présente divers inconvénients parmi lesquels :

  • l'axe de cette gorge de guidage est décalé par rapport à l'extrémité de l'arbre d'enroulement disposé à l'intérieur de la bôme, ce qui peut entraîner un mauvais enroulement de la voile sur l'arbre et la formation de plis ;
  • du fait de la fixité de ladite gorge, la poussée des lattes sur le guindant rend difficile l'envoi, l'affalage ou la réduction de la voile à cause des frottements, ce qui oblige à placer la voile dans le lit du vent ;
  • ces problèmes de frottements et de couples parasites rendent le système inutilisable en pratique sur des voiliers supérieurs à 12 m.
Such a device has various drawbacks, among which:
  • the axis of this guide groove is offset from the end of the winding shaft disposed inside the boom, which can cause the sail to wind up badly on the shaft and the formation of folds;
  • because of the fixity of said groove, the thrust of the slats on the luff makes it difficult to send, lower or reduce the sail because of friction, which forces the sail to be placed in the bed of the wind;
  • these problems of friction and parasitic couples make the system unusable in practice on sailboats longer than 12 m.

Le but de l'invention est de pallier ces inconvénients en proposant un dispositif apte en particulier à l'enroulement à l'intérieur de la bôme d'une grand-voile à lattes, en réduisant substantiellement les frottements et efforts engendrés au niveau de la liaison entre mât et voile et autorisant la réduction de voilure dans une plage d'angle pouvant atteindre 45° tribord ou babord par rapport au lit du vent, dans des conditions mécaniques parfaitement acceptables.The object of the invention is to overcome these drawbacks by proposing a device suitable in particular for winding inside the boom of a battened mainsail, by substantially reducing the friction and forces generated at the level of the connection between mast and sail and authorizing the reduction of sail in an angle range of up to 45 ° starboard or port side relative to the wind bed, in perfectly acceptable mechanical conditions.

A cet effet, l'invention a pour objet un dispositif de guidage de ralingue de guindant notamment d'une voile enroulable sur bôme d'un voilier, caractérisé en ce qu'il est constitué d'une gorge continue dans laquelle est engagée et circule librement la ralingue de guindant, ladite gorge étant disposée à l'arrière du mât et montée pivotante librement autour de son axe, d'une amplitude déterminée de part et d'autre du plan de symétrie du voilier.To this end, the subject of the invention is a device for guiding a rope luff in particular of a sail that can be rolled up on the boom of a sailboat, characterized in that it consists of a continuous groove in which is engaged and circulates freely the luff line, said groove being disposed at the rear of the mast and mounted pivoting freely around its axis, of a determined amplitude on either side of the plane of symmetry of the sailboat.

De préférence, la têtière et les éventuelles lattes de la voile sont reliées à ladite ralingue par l'intermédiaire de coulisseaux en forme de T, la barre horizontale du T étant creuse et entourant, à distance, la ralingue, cependant que la barre verticale du T, d'une part, est reliée auxdites têtières et lattes par une liaison articulée, d'autre part, s'étend à l'intérieur d'une échancrure ménagée dans la voile autour du coulisseau.Preferably, the headrest and any slats of the sail are connected to said headline by means of T-shaped slides, the horizontal bar of the T being hollow and surrounding, at a distance, the headline, while the vertical bar of the T, on the one hand, is connected to said headrests and slats by an articulated connection, on the other hand, extends inside a notch formed in the sail around the slide.

De préférence, ladite barre verticale du T des coulisseaux, présente, en regard des flancs d'entrée de la gorge de guidage de la ralingue, une surface en un matériau à faible coefficient de frottement.Preferably, said vertical bar of the T of the slides, has, opposite the entry flanks of the guide groove of the rope, a surface made of a material with a low coefficient of friction.

Avantageusement, dans le cas d'une voile enroulable sur bôme, ladite gorge de guidage est disposée à l'aplomb de l'extrémité du dispositif d'enroulement de la bôme et est prolongée, à son extrémité inférieure, par un guide conique fendu facilitant la transition de la ralingue et ses coulisseaux, de la gorge vers le dispositif d'enroulement de la voile et, surtout, de ce dernier vers la gorge pour un engagement parfait notamment des coulisseaux.Advantageously, in the case of a sail which can be rolled up on a boom, said guide groove is disposed vertically above the end of the device for winding the boom and is extended, at its lower end, by a split conical guide facilitating the transition from the rope and its sliders, from the groove to the winding device of the sail and, above all, from the latter towards the throat for perfect engagement, in particular of the sliders.

Avec un tel dispositif, le montage pivotant de la gorge de guidage permet à cette dernière de suivre le pivotement de l'ensemble voile-lattes-coulisseaux autour de l'axe de la ralingue, en sorte qu'à l'intérieur de toute la plage de débattement angulaire de cet ensemble, l'éventuelle réduction de la voile s'effectuera correctement avec le minimum de frottements entre, d'une part, la ralingue et les coulisseaux et, d'autre part, la gorge de guidage.With such a device, the pivoting mounting of the guide groove allows the latter to follow the pivoting of the sail-slats-sliders assembly around the axis of the headline, so that inside all the angular range of travel of this assembly, the possible reduction of the sail will be carried out correctly with the minimum of friction between, on the one hand, the headline and the slides and, on the other hand, the guide groove.

D'autres caractéristiques et avantages ressortiront de la description qui va suivre d'un mode de réalisation d'un dispositif selon l'invention, description donnée à titre d'exemple et en regard des dessins annexés sur lesquels :

Other characteristics and advantages will emerge from the description which follows of an embodiment of a device according to the invention, description given by way of example and with reference to the appended drawings in which:
  • Figure 1 is a side elevational view of a battened mainsail rollable on a boom using a device according to the invention;

Sur la figure 1 on a représenté schématiquement en 1 le pont d'un voilier, en 2 le mât supportant une grand-voile 3 à lattes 4, enroulable sur un arbre 5 agencé à l'intérieur de la bôme 6.In FIG. 1, the deck of a sailboat is shown diagrammatically at 1, at 2 the mast supporting a mainsail 3 with slats 4, which can be rolled up on a shaft 5 arranged inside the boom 6.

Conformément à l'invention, la ralingue de guindant 7 de la grand-voile 3 est montée coulissante dans une gorge 8 définie par un profilé 9 à section en forme de C, dont la partie supérieure sur la figure 1 est arrachée pour montrer la ralingue 7.According to the invention, the luff line 7 of the mainsail 3 is slidably mounted in a groove 8 defined by a section 9 with a C-shaped section, the upper part of which in FIG. 1 is cut away to show the headline 7.

Le profilé 9 est fixé verticalement à l'aplomb de l'extrémité de l'arbre d'enroulement 5 et à l'arrière du mât 2, par l'intermédiaire de bagues 10 de paliers disposés à distance les uns des autres le long du profilé 9 et assurant à ce dernier un libre pivotement autour de son axe, d'un angle par exemple d'une centaine de degrés, comme illustré par la figure 4, de part et d'autre du plan de symétrie du voilier symbolisé en 11 sur ladite figure 4. Les bagues de palier 10 sont en nombre nécessaire pour assurer une bonne répartition des charges appliquées par la voile 3 sur la ralingue 7.The profile 9 is fixed vertically vertically to the end of the winding shaft 5 and to the rear of the mast 2, by means of bearing rings 10 arranged at a distance from one another along the profile 9 and ensuring the latter a free pivoting about its axis, of a angle for example of a hundred degrees, as illustrated in FIG. 4, on either side of the plane of symmetry of the sailboat symbolized at 11 in said FIG. 4. The bearing rings 10 are in a number necessary to ensure good distribution of the loads applied by the sail 3 on the headline 7.

Dans le mode de réalisation représenté, les bagues de palier 10 ont une forme générale de C (figure 4) en correspondance avec la section du profilé 9 et sont portées par des corps de palier 12, rapportés sur une pièce de liaison 13, elle-même rapportée sur la face arrière du mât 2, l'ensemble conférant à la gorge 8 la position à l'aplomb de l'extrémité, côté mât, de l'arbre d'enroulement 5, comme indiqué plus haut.In the embodiment shown, the bearing rings 10 have a general shape of C (FIG. 4) in correspondence with the section of the profile 9 and are carried by bearing bodies 12, attached to a connecting piece 13, itself even attached to the rear face of the mast 2, the assembly giving the groove 8 the position perpendicular to the end, mast side, of the winding shaft 5, as indicated above.

La ralingue 7 est un cordage enveloppé dans un repli de la toile de la voile 3, des échancrures 14 étant ménagées dans la voile au droit des jonctions entre les lattes 4 et la ralingue 7.The rope is a cord wrapped in a fold of the canvas of the sail 3, notches 14 being formed in the sail at the junctions between the slats 4 and the rope 7.

Dans ces échancrures 14 sont disposés des coulisseaux 15 en forme générale de T et représentés en vue éclatée sur la figure 3.In these notches 14 are arranged slides 15 in the general shape of a T and shown in exploded view in FIG. 3.

La barre horizontale du T est une pièce tubulaire 16 à l'intérieur de laquelle est enfilée la ralingue 7, sans liaison entre cette dernière et ladite pièce 16.The horizontal bar of the T is a tubular part 16 inside which the headline 7 is threaded, without connection between the latter and said part 16.

Les deux extrémités de la pièce 16 sont manchonnées à l'aide d'une pièce 17 en matériau à faible coefficient de frottement tel qu'une matière plastique.The two ends of the part 16 are sleeved using a part 17 made of a material with a low coefficient of friction such as a plastic material.

La barre verticale du T comporte une tige 18 de section rectangulaire à l'extrémité de laquelle est articulée, autour d'un axe horizontale 19, une latte 4, ladite tige 18 étant entourée d'un manchon coulissant 20, en matériau à faible coefficient de frottement du même type que les pièces 17.The vertical bar of the T comprises a rod 18 of rectangular section at the end of which is hinged, around a horizontal axis 19, a slat 4, said rod 18 being surrounded by a sliding sleeve 20, made of low coefficient material of the same type as the parts 17.

La latte 4 est reliée à la tige 12 via un boîtier de latte conventionnel 21 et son embout cylindrique de liaison 22.The batten 4 is connected to the rod 12 via a conventional batten casing 21 and its cylindrical connecting end piece 22.

L'ensemble de la ralingue 7 avec son enveloppe de toile et des coulisseaux 15 disposés en chapelet le long de la ralingue, peut librement coulisser à l'intérieur du profilé 9. Le diamètre externe des pièces 17 est légèrement supérieur à celui de la ralingue 7 (avec sa toile) et légèrement inférieur au diamètre interne du profilé 9, c'est-à-dire de la gorge de guidage 8.The whole of the rope 7 with its canvas cover and slides 15 arranged in a chain along the rope, can freely slide inside the profile 9. The external diameter of the parts 17 is slightly greater than that of the rope 7 (with canvas) and slightly less than the internal diameter of the profile 9, that is to say of the guide groove 8.

Les frottements s'opèrent donc essentiellement au droit desdites pièces 17.The friction therefore takes place essentially at the level of said parts 17.

L'ensemble tige 18-manchon 20 est dimensionné en sorte de coulisser librement dans la fente longitudinale du profilé 9 définissant l'entrée de la gorge 8. A cet effet, les flancs en regard 23 de l'entrée de la gorge 8 sont sensiblement parallèles et reçoivent les efforts répercutés par les pièces 20 des coulisseaux 15 et émanant des lattes 4.The rod 18-sleeve 20 assembly is dimensioned so as to slide freely in the longitudinal slot of the profile 9 defining the entrance to the groove 8. For this purpose, the facing flanks 23 of the entrance to the groove 8 are substantially parallel and receive the forces reflected by the parts 20 of the slides 15 and emanating from the slats 4.

Il est à noter que les faces en regard 24 (figure 4) de l'ouverture ménagée dans les bagues rotatives 10 dans le prolongement de l'entrée de la gorge 8, se trouvent en retrait des flancs 23 et ne sont donc pas soumis à frottement de la part des coulisseaux 15.It should be noted that the facing faces 24 (FIG. 4) of the opening made in the rotating rings 10 in the extension of the entry of the groove 8, are set back from the sides 23 and are therefore not subjected to friction on the part of the slides 15.

Les bagues 10 et les corps de palier 12 ont une structure particulière.The rings 10 and the bearing bodies 12 have a particular structure.

Succinctement, chaque bague 10 a une forme d'anneau ouvert présentant deux faces d'extrémité 25, planes, parallèles et en forme de C, sur lesquelles sont ménagés deux chemins de roulement en arc de cercle 26 centrés sur l'axe de la bague 10.Briefly, each ring 10 has the shape of an open ring having two end faces 25, flat, parallel and C-shaped, on which are formed two raceways in an arc of a circle 26 centered on the axis of the ring 10.

Dans ces chemins 26 peuvent circuler des billes 27 pouvant également circuler dans un logement ménagé dans une pièce 28 solidaire du corps de palier 12 et rapportée en regard des faces 25.In these paths 26 can circulate balls 27 which can also circulate in a housing formed in a part 28 integral with the bearing body 12 and attached opposite the faces 25.

La forme du logement des pièces 28 est telle qu'entre les pièces 28 et la bague 10 sont ménagés deux chemins de roulement, en boucle fermée, des billes 27. Ces billes 27 sont à la queue leu leu le long de ladite boucle qui s'étend dans un plan cylindrique coaxial à la bague 10 et qui est formée de deux arcs de cercle parallèles, disposés au-dessus l'un de l'autre et reliés à leurs extrémités correspondantes par des arcs de cercle.The shape of the housing of the parts 28 is such that between the parts 28 and the ring 10 are formed two raceways, in a closed loop, of the balls 27. These balls 27 are at the tail leu leu along said loop which s 'extends in a cylindrical plane coaxial with the ring 10 and which is formed of two parallel arcs of a circle, arranged above one another and connected at their corresponding ends by arcs of a circle.

Ainsi, lorsque la bague 10 tourne par rapport au corps de palier 12, les billes 27 circulent le long de la boucle fermée fixe délimitée pour partie dans la pièce 28 et pour partie par une fraction du chemin 26 et les efforts transmis aux bagues 10 par le profilé 9 et émanant de la voile 3, sont transmis au mât 2 dans de bonnes conditions, c'est-à-dire dans l'axe de la ralingue 7 et en parfaite convergence avec le centre de pivotement de celle-ci, quelle que soit la position angulaire de la bague 10 par rapport au corps de palier 12, dans des limites de débattement angulaire déterminées bien entendu et fixées par une saillie fixe 29 (figure 4) mobile dans une gorge en arc de cercle 30 ménagée sur la face cylindrique externe de la bague 10.Thus, when the ring 10 rotates relative to the bearing body 12, the balls 27 circulate along the fixed closed loop delimited partly in the part 28 and partly by a fraction of the path 26 and the forces transmitted to the rings 10 by the profile 9 and emanating from the sail 3, are transmitted to the mast 2 in good conditions, that is to say in the axis of the rope 7 and in perfect convergence with the pivot center of the latter, whatever the angular position of the ring 10 relative to the bearing body 12, within limits of angular clearance determined of course and fixed by a fixed projection 29 (FIG. 4) movable in a groove in an arc 30 formed on the external cylindrical face of the ring 10.

L'angle maximal de débattement angulaire de 200° de la bague 10 illustré par la figure 4 est ainsi délimité par la course maximale de la saillie 29 dans la gorge 30.The maximum angle of angular movement of 200 ° of the ring 10 illustrated in FIG. 4 is thus delimited by the maximum stroke of the projection 29 in the groove 30.

La solidarisation en rotation du profilé 9 et des bagues 10 est assurée par des nervures 31 ménagées sur les flancs externes du profilé 9 et engagées dans des gorges 32 de forme complémentaire ménagées dans la paroi interne cylindrique des bagues 10.The rotation 9 of the profile 9 and the rings 10 is secured by ribs 31 formed on the external sides of the profile 9 and engaged in grooves 32 of complementary shape formed in the cylindrical internal wall of the rings 10.

La têtière 33 est reliée à des coulisseaux 15 solidaires de la ralingue 7.The headrest 33 is connected to slides 15 integral with the headline 7.

A l'extrémité inférieure du profilé 9 (figure 5) est avantageusement agencé un guide conique fendu 34. Les flancs 35 de la fente longitudinale du guide 34 sont dans le prolongement des flancs 23 et vont en s'écartant en sorte de définir, à l'extrémité inférieure du guide 34, une large ouverture 36 surplombant l'extrémité de l'arbre d'enroulement 5 de la bôme 6 et facilitant notamment l'engagement des coulisseaux 15 dans le profilé 9 lors du déploiement de la voile 3.At the lower end of the profile 9 (FIG. 5) is advantageously arranged a split conical guide 34. The sides 35 of the longitudinal slot of the guide 34 are in the extension of the sides 23 and go away so as to define, at the lower end of the guide 34, a wide opening 36 overhanging the end of the winding shaft 5 of the boom 6 and in particular facilitating the engagement of the slides 15 in the profile 9 during the deployment of the sail 3.

Le dispositif de l'invention permet, comme indiqué plus haut, l'envoi et l'affalage de la voile 3 en parfait prolongement de la gorge de guidage 8, c'est-à-dire sans formation de plis parasites lors du roulage de la voile sur l'arbre 5, à n'importe quelle allure et sans pour autant que le bateau soit nécessairement dans le sens du vent, du fait du libre débattement angulaire du profilé 9 sous la pression des lattes 4, sans gêner pour autant le libre coulissement de la ralingue 7 à l'intérieur dudit profilé 9.The device of the invention allows, as indicated above, the sending and lowering of the sail 3 in perfect extension of the guide groove 8, that is to say without the formation of parasitic folds during the rolling of the sail on the shaft 5, at any speed and without necessarily the boat being in the direction of the wind, due to the free angular movement of the profile 9 under the pressure of the slats 4, without hampering the free sliding of the headline 7 inside said profile 9.

L'ensemble lattes 4-coulisseaux 15 présente un encombrement réduit évitant la création d'un volume excessif lors de l'enroulement de la voile 3.The set of 4-slat slats 15 has a reduced overall size avoiding the creation of an excessive volume during the winding of the sail 3.

Le guindant avec ses coulisseaux 15 forme un ensemble continu, de la têtière 33 au point d'amure bas, d'encombrement réduit, coulissant aisément dans le profilé 9 et s'enroulant sans problème sur l'arbre 5 et sous un volume d'encombrement acceptable.The luff with its sliders 15 forms a continuous assembly, from the headrest 33 to the low tack point, of reduced size, sliding easily in the profile 9 and winding without problem on the shaft 5 and in an acceptable volume.

L'agencement du profilé 9 en retrait par rapport au mât 2 laisse l'espace minimal nécessaire au logement du vit de mulet 37.The arrangement of the section 9 set back with respect to the mast 2 leaves the minimum space necessary for housing the mullet saw 37.

La ralingue 7 et ses coulisseaux 15 se déplacent à l'intérieur du profilé 9 suivant un axe qui coïncide avec l'axe de pivotement dudit profilé 9, en sorte que les efforts de traction et compression des lattes 4, chargées de transmettre au mât 2 les forces de propulsion de la voile 3, se répercutent de manière optimale sur le mât 2, sans couple parasite susceptible d'altérer les mouvements de montée et descente de la ralingue 7 à l'intérieur du profilé 9.The rope 7 and its slides 15 move inside the profile 9 along an axis which coincides with the pivot axis of said profile 9, so that the traction and compression forces of the slats 4, responsible for transmitting to the mast 2 the propulsion forces of the sail 3 have an optimum effect on the mast 2, without parasitic torque capable of altering the up and down movements of the headline 7 inside the section 9.

Les coulisseaux 15 autorisent une rotation verticale, autour de l'axe 19, des lattes 4, et ces dernières ne comportent pas d'articulation latérale comme sur les voiles à lattes traditionnelles. Ceci permet aux lattes d'entraîner en rotation les coulisseaux 15 autour de l'axe de la ralingue et, par suite, le profilé tournant 9. L'amplitude de rotation du profilé 9 est de l'ordre de 100° sur chaque bord mais peut être bien entendu adaptée par un simple réglage de la longueur de la gorge 30 dans laquelle circule la butée 29.The sliders 15 allow vertical rotation, around the axis 19, of the slats 4, and the latter do not have a lateral articulation as on traditional slat sails. This allows the slats to rotate the sliders 15 around the axis of the headline and, consequently, the rotating profile 9. The amplitude of rotation of the profile 9 is of the order of 100 ° on each edge but can of course be adapted by a simple adjustment of the length of the groove 30 in which the stop 29 circulates.

Du fait de la facilité et de la sécurité de la manoeuvre de montée et descente de la ralingue 7, le dispositif de l'invention peut être entièrement automatisé.Due to the ease and safety of the raising and lowering operation of the headline 7, the device of the invention can be fully automated.

L'invention s'applique à des voiles à lattes mais peut également s'appliquer à des voiles sans lattes.The invention applies to slatted sails but can also be applied to sails without slats.

Bien que l'invention concerne plus particulièrement les voiliers équipés de bôme à enrouleur, on peut néanmoins envisager le dispositif de guidage de ralingue à guide (profilé 9) pivotant, pour la réduction de la surface d'une grand-voile par prise de ris, la grand-voile étant simplement affalée verticalement en réduisant sa hauteur sur le mât, sans enroulement sur la bôme.Although the invention relates more particularly to sailboats fitted with a furling boom, it is nevertheless possible to envisage the revolving guide line guiding device (profile 9), for reducing the surface of a mainsail by taking reefs , the mainsail being simply collapsed vertically by reducing its height on the mast, without winding on the boom.

Par ailleurs, le dispositif de l'invention peut s'utiliser sur des voiliers de toute taille.Furthermore, the device of the invention can be used on sailboats of any size.

Enfin, l'invention n'est évidemment pas limitée au mode de réalisation représenté et décrit ci-dessus, mais en couvre au contraire toutes les variantes, notamment en ce qui concerne les formes et dimensions des coulisseaux 15, du profilé tournant 9 et de sa gorge de coulissement 8. De même, les bagues rotatives 10 et corps de palier 12 peuvent être remplacés par tout autre moyen permettant le support du profilé 9, son pivotement angulaire suivant un certain angle, éventuellement réglable, et tout en laissant totalement libre d'accès l'intérieur du profilé 9, sur toute sa hauteur.Finally, the invention is obviously not limited to the embodiment shown and described above, but on the contrary covers all its variants, in particular as regards relates to the shapes and dimensions of the slides 15, of the rotary profile 9 and of its sliding groove 8. Likewise, the rotary rings 10 and bearing housing 12 can be replaced by any other means allowing the support of the profile 9, its angular pivoting at a certain angle, possibly adjustable, and while leaving the interior of the profile 9 completely free to access, over its entire height.
