Abstract
Description
La présente invention a essentiellement pour objet une embarcation à voile et/ou à moteur, destinée en particulier à la navigation de plaisance. The present invention essentially relates to a sailing and / or motorized boat, intended in particular for pleasure boating.
On a déJà proposé des bateaux comprenant une coque à carène trilobée possédant, à l'avant, une coque ou un lobe allongé symétrique par rapport au plan longitudinal médian du bateau, et à l'arrière, deux coques ou lobes allongés transversalement espacés et sensiblement symétriques par rapport audit plan médian
Mais avec ce genre de coques, les trois lobes de carène se chevauchent dans le sens longitudinal, comme c'est d'ailleurs le cas des bateaux appelés généralement trimarans, de sorte que la maniabilité et la possibilité de changement de direction de tels bateaux sont loin d'être satisSaisantes. Boats have already been proposed comprising a three-lobed hull having, at the front, an elongated hull or lobe symmetrical with respect to the median longitudinal plane, and at the rear, two transversely spaced and substantially elongated hulls or lobes symmetrical with respect to said median plane
But with this type of hull, the three hull lobes overlap in the longitudinal direction, as is the case with boats generally called trimarans, so that the maneuverability and the possibility of change of direction of such boats are far from satisfactory.
La présente invention a pour but de remédier notamment aux inconvénients ci-dessus, en proposant une nouvelle embarcation à carène trilobéespécia} et susceptible de conférer à ladite embarcation des qualités exceptionnelles de maniabilité et de stabilité en cours de navigation. The object of the present invention is to remedy the above drawbacks in particular, by proposing a new hulled boat with three-lobed hulls and capable of giving said boat exceptional qualities of maneuverability and stability during navigation.
A cet effet, l'invention a pour objet une embarcation, notamment à voile, du type comprenant une coque à carène trilobée, sensiblement symétrique par rapport au plan longitudinal médian de l'embarcation, et possédant, à l'avant, un lobe allongé et, à l'arrière, deux lobes allongés transversalement espacés, caractérisée en ce qutau moins les parties avant des deux lobes arrières de la carène convergent vers ledit plan médian ou en divergent. To this end, the subject of the invention is a boat, in particular a sailboat, of the type comprising a hull with a three-lobed hull, substantially symmetrical with respect to the median longitudinal plane of the boat, and having, at the front, an elongated lobe and, at the rear, two transversely spaced elongated lobes, characterized in that at least the front parts of the two rear lobes of the hull converge towards or diverge from said median plane.
Selon une autre caractéristique de l'invention, le plan médian de la partie avant de chaque lobe arrière est incliné d'un angle compris entre environ 2 et 200 par rapport au plan longitudinal médian de l'embarcation, tandis que le plan médian de la partie arrière de chaque lobe arrière est au moins approximativement parallèle audit plan longitudinal médian de l'embarcation. According to another characteristic of the invention, the median plane of the front part of each aft lobe is inclined at an angle of between approximately 2 and 200 relative to the longitudinal median plane of the boat, while the median plane of the stern part of each aft lobe is at least approximately parallel to said median longitudinal plane of the boat.
Il faut encore noter que, selon l'invention, le plan médian précité de la partie arrière de chaque lobe arrière est incliné d'un angle compris entre environ O et 50 par rapport au planlongitudinal médian de l'embarcation. It should also be noted that, according to the invention, the aforementioned median plane of the rear part of each rear lobe is inclined at an angle of between approximately 0 and 50 relative to the median longitudinal plane of the boat.
Selon encore une autre caractéristique de l'invention, les deux lobes arrières précités sont des parties intégrant3y de la coque de l'embarcation, ou bien sont montés pivotant sur celle-ci, dans quel cas lesdits lobes sont simultanément manoeuvrables au moyen d'une barre, roue ou analogue. According to yet another characteristic of the invention, the aforementioned two aft lobes are integral parts of the hull of the boat, or are pivotally mounted thereon, in which case said lobes are simultaneously maneuverable by means of a bar, wheel or the like.
Selon un mode de réalisation préféré, la coque présente un contour apparent horizontal au moins approximativement triangulaire avec un lobe précité vers chaque sommet de ce contour, la surface immergée des lobes arrières étant nettement espacée, dans le sens longituninal, de la surface immergée du lobe avant. According to a preferred embodiment, the shell has an apparent horizontal contour at least approximately triangular with an aforementioned lobe towards each vertex of this contour, the submerged surface of the rear lobes being clearly spaced, in the longitudinal direction, from the submerged surface of the lobe before.
On ajoutera encore que3 selon l'invention, le contour apparent horizontal de la coque présente une partie axent sensiblement ogivale raccordée par une partie intermédiaire sensiblement rectiligne à une partie arrière au moins approximativement en forme de trapèze curviligne. It will also be added that, according to the invention, the apparent horizontal contour of the shell has a substantially ogival axial part connected by a substantially rectilinear intermediate part to a rear part at least approximately in the shape of a curvilinear trapezoid.
Une telle forme de coque présente non seulement des qualités sur le plan esthétique, mais également sur le plan fonctionnel, en ce qui concerne l'aménagement intérieur de l1embarcation. Such a hull shape presents not only qualities on the aesthetic level, but also on the functional level, as regards the interior layout of the boat.
Suivant encore une autre caractéristique de l'invention, la coque précitée est équipée d'un mât tétrapode comportant au moins une plate-forme susceptible de supporter un individu. According to yet another characteristic of the invention, the aforementioned hull is equipped with a tetrapod mast comprising at least one platform capable of supporting an individual.
D'autres caractéristiques et avantages de l'invention apparaitront mieux dans la description détaillée qui suit et se réfère aux dessins annexds, donnés uniquement à titre d'exemple, et dans lesquels
-la figure 1 est une vue en élévation d'une embarcation conforme à l'invention;
-la figure 2 est une vue en plan de dessus de cette embarcation
-la figure 3 est une vue en plan de dessous illustrant plusieurs modes de réalisation des lobes arrières sous la coque ; et
-la figure 4 est une vue de l'arrière et en bout de l'embarcation, suivant la flèche IV de la figure 3.Other characteristics and advantages of the invention will appear better in the detailed description which follows and which refers to the appended drawings, given only by way of example, and in which
FIG 1 is an elevational view of a boat according to the invention;
FIG 2 is a plan view from above of this boat
FIG. 3 is a bottom plan view illustrating several embodiments of the rear lobes under the hull; and
FIG. 4 is a view from the rear and at the end of the boat, according to arrow IV of FIG. 3.
Suivant exemple de réalisation représenté, et en se reportant notamment aux figures 1 et 4, une embarcation 1 conforme à l'invention comprend essentiellement une coque 2 à carène trilobée,sensiblement symétrique par rapport au plan longitudinal médian 3 de l'embarcation 1. According to the embodiment shown, and with particular reference to FIGS. 1 and 4, a boat 1 according to the invention essentially comprises a hull 2 with a three-lobed hull, substantially symmetrical with respect to the median longitudinal plane 3 of the boat 1.
Plus précisément, le dessous de la coque 2 comporte à 'n e o k > be allongé 4 syméiri;e rapport au plan longitudinal médian 3, et, à l'arrière deux lobes allongés 5 transversalement espacés et symétriques par rapport audit plan longitudinal médian 3. More precisely, the underside of the shell 2 comprises at 'n e o k> be elongated 4 symmetry; e relative to the median longitudinal plane 3, and, at the rear two elongated lobes 5 transversely spaced and symmetrical with respect to said median longitudinal plane 3.
Suivant une caractéristique essentielle de la présente invention, et comme on le voit bien sur la figure 3, les parties avant 5a des deux lobes arrières 5 sont inclinées d'un certain angle par rapport au plan longitudinal médian 3. According to an essential characteristic of the present invention, and as can be seen in FIG. 3, the front parts 5a of the two rear lobes 5 are inclined at a certain angle relative to the median longitudinal plane 3.
Plus précisément, et suivant un premier mode de réalisation, chaque lobe arrière 5 présente une partie avant 5b (visible en traits pleins sur la figure 3, et également sur la figure 4), qui converge vers le plan longitudinal médian 3 et qui forme ainsi un certain angle avec celui-ci qui peut entre compris entre environ 2 et 200. More precisely, and according to a first embodiment, each rear lobe 5 has a front part 5b (visible in solid lines in FIG. 3, and also in FIG. 4), which converges towards the median longitudinal plane 3 and which thus forms a certain angle with it which can range between about 2 and 200.
Suivant un autre mode de réalisation, et comme cela est illustré en traits mixtes sur la figure 3, la partie avant 5c de chaque lobe arrière 5 peut diverger du plan longitudinal médian 3 de façon à former un angle par rapport à celui-ci, qui peut être également compris entre environ 2et 200. According to another embodiment, and as illustrated in phantom in Figure 3, the front part 5c of each rear lobe 5 can diverge from the median longitudinal plane 3 so as to form an angle with respect thereto, which can also be between about 2 and 200.
On a repéré en A l'angle en question, formé entre le plan longitudinal médian 3 et la partie avant 5b de chaque lobe arrière 5 dans le cas du premier mode de réalisation, c'est-à-dire dans le cas où la partie avant de chaque lobe arrière 5 converge vers ledit plan médian
Qu'il s'agisse d'un mode de réalisation ou de l'autre, la partie arrière 5d de chaque lobe arrière 5 est approximativement parralèle au plan longitudinal médian 3 ou bien forme un très petit angle avec celui-ci, comme on l'a montré en B sur la figure 3. Ainsi, l'angle B entre le plan médian de la partie arrière 5d des lobes arrières 5 et le plan longitudinal médian 3 de l'embarcation 1 peut être compris entre approximativement O et 5 . At the angle in question, formed between the median longitudinal plane 3 and the front part 5b of each rear lobe 5 has been identified in the case of the first embodiment, that is to say in the case where the part front of each rear lobe 5 converges towards said median plane
Whether it is an embodiment or the other, the rear part 5d of each rear lobe 5 is approximately parallel to the median longitudinal plane 3 or else forms a very small angle with it, as shown in FIG. 'has shown at B in FIG. 3. Thus, the angle B between the median plane of the rear part 5d of the aft lobes 5 and the median longitudinal plane 3 of the boat 1 can be between approximately 0 and 5.
Les deux lobes arrières 5 de la carène de ltembarca- tion peuvent faire partie intégrante de la coque, en venant de moulage avec celle-ci par exemple,dans le cas d'une coque réalisée en matière plastique. Mais une autre disposition avantageuse selon l'invention peut consister à prévoir des lobes-arrières 5 en quelque sorte indépendants de la coque 2 et montés pivotant sur celle-ci au moyen dlun axe transversal montré schématiquement en 6 sur la figure 3. The two rear lobes 5 of the hull of the vessel may form an integral part of the hull, coming from molding therewith for example, in the case of a hull made of plastic. However, another advantageous arrangement according to the invention may consist in providing rear lobes 5 which are somewhat independent of the shell 2 and mounted so as to pivot on the latter by means of a transverse axis shown diagrammatically at 6 in FIG. 3.
Dans ce cas là, les lobes arrières 5 peuvent jouer le r81e d'un gouvernail en étant simultanément manoeuvrables au moyen d'un système approprié et actionné par une barre, roue ou analogue non représentée.In this case, the rear lobes 5 can play the role of a rudder while being simultaneously maneuverable by means of an appropriate system and actuated by a bar, wheel or the like, not shown.
Bien entendu, la prévision de lobes arrières 5 intégraux à la coque 2 ou mobiles par rapport à celle-ci, doit s'entendre comme n'excluant pas la possibilité de prévoir pour la partie avant 5a desdits lobes une forme convergente ou divergente par rapport au plan longitudinal médian 3 de ltembarcation 1. Of course, the provision of rear lobes 5 integral with the shell 2 or movable relative thereto, must be understood as not excluding the possibility of providing for the front part 5a of said lobes a shape which is convergent or diverging with respect to at the median longitudinal plane 3 of the boat 1.
Comme il apparat clairement sur la figure 2, la forme, vue en plan de dessus, de l'embarcation 1 est approximativement triangulaire, étant bien entendu, comme on le voit sur la figure 3, qu'un lobe se trouve situé vers chaque sommet du triangle approximatif que forme le dessous de la coque 2. As it clearly appears in FIG. 2, the shape, seen in plan from above, of boat 1 is approximately triangular, it being understood, as seen in FIG. 3, that a lobe is located towards each vertex of the approximate triangle formed by the underside of the shell 2.
Revenant à la figure 2, on voit quele contour de la coque 2 présente une partie avant 7 sensiblement ogivale raccordée par une partie intermédiaire 8 sensiblement rectiligne à une partie arrière14 qui présente sensiblement la forme d'un trapèze curviligne.Returning to FIG. 2, it can be seen that the outline of the shell 2 has a substantially ogival front part 7 connected by a substantially rectilinear intermediate part 8 to a rear part 14 which has substantially the shape of a curvilinear trapezoid.
Il est important de noter ici, comme on le voit sur la figure 3, que les trois lobes 4 et 5 sont ainsi prévus que, dans le sens longitudinal, ils ne se chevauchent pas, ce qui confère au bateau selon l'invention des qualités exceptionnelles de maniabilité en cours de navigation. Plus précisément, la surface immergée des lobes arrières 5 est nettement espacée, dans le sens longitudinal,de la surface immergée du lobe avant 4, comme cela se voit en considérant la ligne de flottaison visible en 9 sur la figure 1. En d'autres termes, il ne risque pas d'y avoir d'interactions entre les coques ou lobes45 lors de l'avance du bateau, ce qui lui assure une bonne maniabilité sans pour cela nuire à sa stabilité qui est inhirente à ses trois points d'appui sur l'eau gracie aux trois lobes espacés 4 et 5. It is important to note here, as can be seen in FIG. 3, that the three lobes 4 and 5 are thus provided that, in the longitudinal direction, they do not overlap, which gives the boat according to the invention qualities exceptional maneuverability during navigation. More precisely, the submerged surface of the rear lobes 5 is clearly spaced, in the longitudinal direction, from the submerged surface of the front lobe 4, as can be seen by considering the water line visible at 9 in FIG. 1. In others terms, there is no risk of interactions between the hulls or lobes45 during the advance of the boat, which ensures good maneuverability without affecting the stability which is inherent in its three support points on water pardoned by the three spaced lobes 4 and 5.
Une embarcation 1 conforme à l'invention sera avantageusement équipée d'un mSt tétrapode 10 comme on le voit bien sur les figures 1, 2, 4, lequel mSt peut comporter au moins une plate-forme telle que 11, susceptible de supporter un individu qui peut y accéder par une petite échelle ou analogue 12. Une telle plate-forme sera particulièrement utile pour faire le point ou des observations. A boat 1 according to the invention will advantageously be equipped with a tetrapod mSt 10 as can be seen in FIGS. 1, 2, 4, which mSt can comprise at least one platform such as 11, capable of supporting an individual who can access it by a small ladder or the like 12. Such a platform will be particularly useful for taking stock or making observations.
Comme on le voit sur la figure 1, une embarcation 1 selon l'invention peut entre équipée d'au moins une voile 13 maintenue, sur un mat ou analogue 20 monté entre l'avant du bateau et le mSt tétrapode 10. Il est évidemment possible d'équiper l'embarcation 1 d'un moteur (non représenté) susceptible d'entratner une hélice 15, comme cela est bien connu. Enfin, comme on le voit sur la figure 2, l'embarcation 1 peut être aménagée d'un manière appropriée et comprendre à l'avant par exemple un espace 16 avec table 17 faisant suite au poste de pilotage 18, et, à l'arrière, une plage ou analogue 19, faisant par exemple office de solarium pour les passagers. As can be seen in FIG. 1, a boat 1 according to the invention can between fitted with at least one sail 13 maintained, on a mast or the like 20 mounted between the front of the boat and the tetrapod mSt 10. It is obviously possible to equip boat 1 with a motor (not shown) capable of driving a propeller 15, as is well known. Finally, as can be seen in FIG. 2, the boat 1 can be fitted out in an appropriate manner and include at the front for example a space 16 with table 17 following the cockpit 18, and, at the rear, a beach or the like 19, for example acting as a solarium for passengers.
On a donc réalisé selon-l'invention une embarcation à voile et/ou à moteur qui est remarquablement stable et maniable et qui peut être utilisée sans aucun risque par des navigateurs m8me inexpérimentés. There has therefore been produced according to the invention a sailing and / or motorized boat which is remarkably stable and manageable and which can be used without any risk by even inexperienced sailors.
Bien entendu, l'invention n'est nullement limitée aux modes de réalisation décrits et illustrés qui n'ont été donnés qu'à titre d'exemple. L'invention comprend donc tous les équivalents techniques des moyens décrits ainsi que leurs combinaisons si celles-ci sont effectuées suivant son esprit et mises en oeuvre dans le cadre de la protection revendRpée. . Of course, the invention is in no way limited to the embodiments described and illustrated which have been given only by way of example. The invention therefore includes all the technical equivalents of the means described and their combinations if these are carried out according to the spirit and implemented in the context of the protection claimed. .
