Description

« Voilier de course ou de croisière à mât implanté » "Racing or cruising sailboat with mast installed"
La présente invention a pour objet un voilier de course ou de croisière comportant une coque fermée par un pont et dans laquelle est implantée l'extrémité inférieure d'un mât portant la voilure.The present invention relates to a racing or cruising sailboat comprising a hull closed by a bridge and in which is installed the lower end of a mast carrying the wing.
On a pu observer, ces dernières années, un développement considérable de la navigation de plaisance et nombreux sont les particuliers qui ont déjà acquis ou envisagent d'acquérir un voilier. La flotte de plaisance actuelle est principalement constituée, en particulier dans le domaine des embarcations de taille moyenne, de voiliers habitables monocoques relativement peu onéreux et largement satisfaisants du point de vue du confort et des possibilités d'aménagement inté- rieur.We have observed, in recent years, a considerable development in pleasure boating and many individuals have already acquired or are planning to acquire a sailboat. The current pleasure fleet is mainly made up, in particular in the field of medium-sized boats, of monohull habitable sailboats which are relatively inexpensive and largely satisfactory from the point of view of comfort and interior design possibilities.
Le gréement de ces voiliers est habituellement constitué d' un mât et de haubans dont le rôle est de le maintenir et de le consolider.The rigging of these sailboats usually consists of a mast and shrouds whose role is to maintain and consolidate it.
L' apparition de voiliers dont la coque est non plus en bois mais dans des matériaux dits composites, en particulier des stratifiés (carbone époxy) a conduit à proposer au public des voiliers dans lesquels le mât est directement implanté dans la coque, ce qui permet de supprimer les haubans latéraux et donc de simplifier notablement la structure du bateau.The appearance of sailboats whose hull is no longer made of wood but of so-called composite materials, in particular laminates (epoxy carbon) has led to the public offering sailboats in which the mast is directly implanted in the hull, which allows to remove the side stays and therefore significantly simplify the structure of the boat.
Une telle conception a, cependant, pour corollaire une augmentation importante du poids du gréement, vu que le mât doit ainsi être sensiblement plus lourd avec un centre de gravité situé très haut ; ceci est pénalisant et nuit dans une large mesure à la vitesse du bateau, en particulier lorsque le vent devient important.Such a design has, however, as a corollary a significant increase in the weight of the rigging, since the mast must thus be substantially heavier with a very high center of gravity; this is penalizing and harms to a large extent the speed of the boat, especially when the wind becomes strong.
Cette situation est d' autant plus désavantageuse que, notamment sous l'influence des grandes courses transocéaniques, de plus en plus de plaisanciers recherchent la performance sportive et souhaitent donc acquérir un voilier qui soit le plus rapide possible. La présente invention a pour objet de proposer un voilier de course ou de croisière à mât implanté du type susmentionné de nature à satisfaire à ces exigences.This situation is all the more disadvantageous since, in particular under the influence of major ocean racing, more and more boaters are looking for sporting performance and therefore wish to acquire a sailboat that is as fast as possible. The object of the present invention is to propose a racing or cruising sailboat with an implanted mast of the aforementioned type capable of meeting these requirements.
Un tel voilier est caractérisé en ce que le mât est un mât basculant exempt de haubanage latéral monté pivotant notamment sur paliers autour d'au moins un axe essentiellement horizontal, cet axe coïncidant avec l'axe longitudinal de la coque ; par suite de cette faculté de basculement babord-tribord, quelles que soient les conditions atmosphériques, le centre de gravité du mât peut être placé au vent, au centre de rotation du voilier, et le plan de voilure perpendiculaire aux filets d'air.Such a sailboat is characterized in that the mast is a tilting mast free of guying mounted pivotally mounted in particular on bearings around at least one essentially horizontal axis, this axis coinciding with the longitudinal axis of the hull; as a result of this port-starboard tilting ability, whatever the atmospheric conditions, the mast center of gravity can be placed in the wind, at the center of rotation of the sailboat, and the sail plane perpendicular to the air streams.
Selon une caractéristique préférentielle de l'invention, le mât est un mât tournant et basculant monté pivotant autour de trois axes, perpendiculaires entre eux, à savoir un axe vertical, l'axe de basculement babord-tribord et un axe essentiellement horizontal perpendiculaire à cet axe de basculement et peut donc être orienté dans toutes les directions . Conformément à l'invention, un tel mât peut, avantageusement, être monté sur un palier de type rotule fixé au niveau du pont du voilier ; parallèlement, son pied peut coulisser sur un rail de préférence en carbone inséré en fond de coque . Cette configuration permet d'augmenter, d'une part, le couple de redressement du voilier, suite au déplacement du centre de gravité du mât au vent de celui-ci et, d'autre part, la force propulsive aérodynamique vu que le mât peut être orienté perpendiculairement aux filets d'air, et même développer un léger effet de portance . On obtient, parallèlement, une diminution de la traînée compte tenu de 1 ' absence de haubans .According to a preferred characteristic of the invention, the mast is a rotating and tilting mast mounted pivoting about three axes, perpendicular to each other, namely a vertical axis, the port-starboard tilting axis and an essentially horizontal axis perpendicular to this tilt axis and can therefore be oriented in all directions. According to the invention, such a mast can advantageously be mounted on a ball-type bearing fixed at the deck of the sailboat; at the same time, its base can slide on a rail, preferably made of carbon, inserted at the bottom of the hull. This configuration makes it possible to increase, on the one hand, the righting moment of the sailboat, following the displacement of the center of gravity of the mast in the wind thereof and, on the other hand, the aerodynamic propelling force since the mast can be oriented perpendicular to the air streams, and even develop a slight lift effect. At the same time, a reduction in drag is obtained taking into account the absence of shrouds.
Selon une autre caractéristique de l'invention, le mât coopère, par son extrémité inférieure, avec des orga- nés de manoeuvre permettant de l'orienter et de le bloquer dans une position déterminée.According to another characteristic of the invention, the mast cooperates, by its lower end, with operating elements making it possible to orient and block it in a determined position.
Un tel réglage peut être effectué manuellement au moyen de leviers de commande mis à la disposition du barreur. On peut, également, envisager de prévoir une commande automatique de l'orientation du mât à partir d'organes de détection de la position du voilier coopérant avec un système d'asservissement électronique connu en lui-même. II est à noter qu'en cours de navigation, les efforts exercés sur le mât sont repris par le palier à rotule et par les organes de manoeuvre.Such an adjustment can be carried out manually by means of control levers made available to the coxswain. It is also possible to envisage providing an automatic control of the orientation of the mast from members for detecting the position of the sailboat cooperating with an electronic control system known in itself. It should be noted that during navigation, the forces exerted on the mast are taken up by the spherical bearing and by the operating members.
Selon une caractéristique non limitative de l'invention, le mât peut respectivement basculer d'un angle de ± 45° autour d'un axe essentiellement horizontal coïncidant avec l'axe longitudinal de la coque et, le cas échéant, autour d'un axe lui aussi essentiellement horizontal et perpendiculaire à cet axe longitudinal .According to a non-limiting characteristic of the invention, the mast can respectively tilt by an angle of ± 45 ° around an essentially horizontal axis coinciding with the longitudinal axis of the hull and, if necessary, around an axis also essentially horizontal and perpendicular to this longitudinal axis.
Selon une autre caractéristique non limitative de l'invention, le mât peut basculer d'un angle pouvant dépasser ± 90° autour d'un axe essentiellement vertical perpendiculaire à l'axe longitudinal de la coque.According to another non-limiting characteristic of the invention, the mast can tilt by an angle which can exceed ± 90 ° around an essentially vertical axis perpendicular to the longitudinal axis of the hull.
On a en effet pu établir qu'une telle faculté de basculement du mât autour de chacun de ses trois axes de pi- votement est suffisante pour s'adapter à toutes les conditions de navigation (gîte, tangage ou roulis) .We have indeed been able to establish that such a tilting ability of the mast around each of its three tilt axes is sufficient to adapt to all navigation conditions (heel, pitch or roll).
Selon une autre caractéristique de l'invention, le mât a une section en forme d'aile ; une telle configuration est particulièrement avantageuse sur un plan aérodynami- que vu qu'elle entraîne une diminution sensible de la traînée ou résistance à l'avancement, et parallèlement sur le plan structurel au niveau de la rigidité du mât : en effet, la toile de grand voile est alors montée de manière à solliciter le mât selon sa plus grande inertie. II est à noter que, conformément à l'invention, la rigidité latérale du mât est assurée exclusivement par celui-ci, en particulier dans le cas d'un profil en aile. La rigidité longitudinale peut, quant à elle, être « consolidée » par les drisses des voiles renvoyées vers l'arrière ou un hauban avant longitudinal à poste (étai) raidi par une bastaque si cet étai sert de support au guindant d'une voile d'avant par exemple. Les caractéristiques du voilier qui fait l'objet de l'invention seront décrites plus en détail en se référant aux dessins annexés dans lesquels :According to another characteristic of the invention, the mast has a wing-shaped section; such a configuration is particularly advantageous on an aerodynamic level since it results in a significant reduction in drag or resistance to advancement, and in parallel on the structural level at the level of the rigidity of the mast: in fact, the canvas of the mainsail is then mounted so as to urge the mast according to its greatest inertia. It should be noted that, in accordance with the invention, the lateral rigidity of the mast is ensured exclusively by the latter, in particular in the case of a wing profile. Longitudinal stiffness can, for its part, be "consolidated" by the halyards of the sails returned to the rear or a longitudinal front shroud with post (forestay) stiffened by a bastaque if this forestay is used to support the luff of a sail of 'before for example. The characteristics of the sailboat which is the subject of the invention will be described in more detail with reference to the accompanying drawings in which:
- la figure 1 est une vue schématique d'un voilier conforme à 1 ' invention,FIG. 1 is a schematic view of a sailboat according to the invention,
- la figure la est une vue détaillée de la rotule et du pied du mât ,- Figure la is a detailed view of the ball joint and the foot of the mast,
- les figures 2a, 2b et 2c sont des schémas représentant les différents axes de pivotement du mât, - les figures 3a et 3b représentent respectivement un voilier classique et un voilier conforme à l'invention en cours de navigation.- Figures 2a, 2b and 2c are diagrams showing the different pivot axes of the mast, - Figures 3a and 3b respectively represent a classic sailboat and a sailboat according to the invention during navigation.
Il est à noter que les figures représentent à titre d'exemple un mât basculant et tournant articulé sur ro- tule ; cette configuration bien que préférentielle ne doit bien entendu pas être considérée comme étant limitative de 1 ' invention.It should be noted that the figures show by way of example a tilting and rotating mast articulated on a ball; this configuration, although preferred, should of course not be considered as limiting the invention.
Selon la figure 1, le voilier conforme à l'invention est essentiellement constitué d'une coque 1 qui est fermée par un pont 2 à sa partie supérieure et se prolonge vers le bas par une quille 3, de manière à assurer la flottaison ainsi que d'un mât 4 implanté dans la coque 1 et portant la voilure non représentée.According to FIG. 1, the sailboat according to the invention essentially consists of a hull 1 which is closed by a bridge 2 at its upper part and is extended downwards by a keel 3, so as to ensure the flotation as well as a mast 4 installed in the hull 1 and carrying the wing not shown.
Plus précisément et selon la figure la, le mât 4 est monté sur un palier de type rotule 5 fixé au niveau du pont 2 et coulisse, par son extrémité inférieure 6 sur un rail en carbone 7 inséré en fond de coque ; des organes de manoeuvre non représentés permettent d'orienter le mât 4 et de le bloquer dans différentes positions angulaires à partir du cockpit .More precisely and according to FIG. 1 a, the mast 4 is mounted on a ball-type bearing 5 fixed at the level of the deck 2 and slides, by its lower end 6 on a carbon rail 7 inserted at the bottom of the hull; operating members not shown make it possible to orient the mast 4 and to block it in different angular positions from the cockpit.
Selon les figures 2a, 2b et 2c, le mât 4 peut respectivement basculer d'un angle α autour d'un axe perpendiculaire à l'axe longitudinal x-x' de la coque 1 (figure 2a) , d'un angle β autour d'un axe coïncidant avec cet axe longitudinal x-x' (figure 2b) ou encore d'un angle γ autour d'un axe essentiellement vertical perpendiculaire à ces deux axes de pivotement (figure 2c) . Les angles de basculement α, β maxima sont tous deux de 45° dans un sens ou dans un autre tandis que l'angle γ maximum peut éventuellement même dépasser ± 90°.According to Figures 2a, 2b and 2c, the mast 4 can respectively tilt by an angle α around an axis perpendicular to the longitudinal axis xx 'of the shell 1 (Figure 2a), by an angle β around an axis coinciding with this longitudinal axis xx '(Figure 2b) or an angle γ around an essentially vertical axis perpendicular to these two pivot axes (Figure 2c). The maximum tilt angles α, β are both 45 ° in one direction or another while the maximum angle γ can possibly even exceed ± 90 °.
Selon la figure 2c, le mât 4 a une section en forme d'aile ce qui permet de garantir une rigidité latérale maxima compte tenu du fait que la grand voile V représentée schématiquement sollicite celui-ci selon sa plus grande inertie .According to FIG. 2c, the mast 4 has a section in the shape of a wing which makes it possible to guarantee maximum lateral rigidity taking into account the fact that the mainsail V shown diagrammatically urges the latter according to its greatest inertia.
Selon la figure 3a, en présence d'un vent dirigé selon la flèche A, le voilier s'incline latéralement (gîte) en entraînant, bien entendu, le mât 4 dans ce mouvement ; l'avancement du voilier est alors pénalisé par la gravité g du mât 4 qui s'exerce verticalement à partir du centre de gravité G de celui-ci par la diminution de la surface proje- tée de la voilure sur un plan vertical, par l'orientation des filets d'air qui font un angle de 70 à 75° avec la voilure.According to Figure 3a, in the presence of a wind directed along arrow A, the sailboat tilts laterally (heel), of course, driving the mast 4 in this movement; the advancement of the sailboat is then penalized by the gravity g of the mast 4 which is exerted vertically from the center of gravity G thereof by the reduction of the projected surface of the sail on a vertical plane, by l orientation of the air streams which make an angle of 70 to 75 ° with the airfoil.
Selon la figure 3b, l'invention permet de supprimer cet inconvénient grâce à l'orientation au vent du mât 4 qui permet le déplacement du centre de gravité G au centre de rotation du bateau grâce au pivotement de ce mât et ainsi de présenter la totalité de la surface de voilure en tant que surface projetée sur un plan vertical et une orientation des filets d'air à 90° de la voile. According to FIG. 3b, the invention makes it possible to eliminate this drawback thanks to the windward orientation of the mast 4 which allows the displacement of the center of gravity G at the center of rotation of the boat thanks to the pivoting of this mast and thus to present the whole of the sail surface as a surface projected on a vertical plane and an orientation of the air streams at 90 ° to the sail.
