Abstract
Description
Dans la navigation des b teaux - voile, la coque du bâteau prend dans certaines directions relatives du vent une inclinaison en érection até- rale appelée gite. Ce phénomène contre toute apparence réa-uit la vitesse d'avance du bateau et rend la navigationmalaisée. In the navigation of boats, the hull of the boat takes in certain relative directions of the wind an inclination in an erection called gite. This phenomenon against all appearance reacts to the speed of advance of the boat and makes navigation difficult.
Pour remédier a cet inconvénient, la technique antérieure a prévu des balasts élevés a l'extrémité inférieure de la quille du bateau. Cette solution présente l'inconvénient d'un cou très élevé et réait les possibilités du transport du bateau sur route et son utilisation dans la navigation côtière dans des régions grandes différences de hauteur 'eau au cours des marées. To overcome this drawback, the prior art has provided high ballasts at the lower end of the boat's keel. This solution has the disadvantage of a very high neck and makes possible the transport of the boat on the road and its use in coastal navigation in regions with great differences in height during the tides.
L'invention a pour objet de concevoir un bateau a voile permettant de remédier a ces inconvénients et qui permet de réduire oensidérablement la gîte du bAteau dans les conditions de vent évoquees ci-dessus. The object of the invention is to design a sailing boat which makes it possible to remedy these drawbacks and which makes it possible to considerably reduce the heeling of the boat under the wind conditions mentioned above.
Le bAteau selon l'invention est un bâteau a voile perfectionné du type a quille fixe, caractérisé en ce qu'il comprend a l'extremite inférieure de sa quille, un volet s'étendant dans le sens longitudinal de la coque du bâteau et qui est monté pivotant autour d'un arbre vertical. The boat according to the invention is an improved sailboat of the fixed keel type, characterized in that it comprises at the lower end of its keel, a flap extending in the longitudinal direction of the hull of the boat and which is pivotally mounted around a vertical shaft.
Suivant un mode de réalisation préféré, ledit volet est positionné dans un logement creux prévu a l'extrémité inférieure de la quille et qui est ouvert vers le bas. According to a preferred embodiment, said flap is positioned in a hollow housing provided at the lower end of the keel and which is open downwards.
De préférence, ledit arbre vertical est situé a l'extrémité avant dudit volet. Preferably, said vertical shaft is located at the front end of said flap.
Suivant une variante, ledit arbre vertical est situé dans la partie centrale dudit volet. According to a variant, said vertical shaft is located in the central part of said flap.
Suivant un mode de réalisation avantageux, le pivotement dudit volet autour de l'axe vertical est commandé par un moteur actionné en fonction de la gîte de la coque dans un sens ou dans un autre. According to an advantageous embodiment, the pivoting of said flap around the vertical axis is controlled by a motor actuated as a function of the heeling of the hull in one direction or another.
Dans le bAteau selon l'invention, l'écartement du volet de l'axe longitudinal de la coque permet de compenser efficacement la gîte du bAteau. In the boat according to the invention, the spacing of the flap from the longitudinal axis of the hull makes it possible to effectively compensate for the heel of the boat.
La structure selon l'invention est simple et peu coûteuse. The structure according to the invention is simple and inexpensive.
On comprendra aisément que le moteur actionnant le volet selon l'invention peut être commandé par certains mécanismes d'action a tout moment de la gîte instantanée du bateau pour régler la position du volet de sorte que celui-ci apporte une compensation importante a cette gîte. It will easily be understood that the motor actuating the shutter according to the invention can be controlled by certain action mechanisms at any time from the instant heel of the boat to adjust the position of the shutter so that it provides significant compensation for this heel .
D'autres avantages de l'invention ressortiront de la description qui va suivre et en se référant aux dessins annexés sur lesquels
La figure i est une vue en coupe longitudinale verticale schématique du premier mode de réalisation préféré du bâteau selon l'invention et
Laa figure 2 est une vue ccrresponnart à celle de la figure 1 deuxième mode de réalisation préféré du bateau selor. l'invention.Other advantages of the invention will emerge from the description which follows and with reference to the appended drawings in which
FIG. I is a schematic vertical longitudinal section view of the first preferred embodiment of the boat according to the invention and
Laa Figure 2 is a view ccrresponnart to that of Figure 1 second preferred embodiment of the selor boat. the invention.
Le bateau représenté à la figure 1 comprend une coque '1) munie d'une quille fixe (2). Il s'aait du bAteau à voile dont le mât et le voiles ne sont pas représentés ici. The boat shown in Figure 1 comprises a hull '1) provided with a fixed keel (2). There was a sailing boat whose mast and sails are not represented here.
Suivant l'invention, la quille (2) comporte à son extrémité inférieure un volet de eom?enset:on de glte :4 étendant e repos dans le sens de l'axe longitudinal de la coque ', et qui est a préférence logé dans un logement creux (3) prévu à l'extrémité inférieure de la quille (2) et ouvert vers le bas. According to the invention, the keel (2) comprises at its lower end a flap of eom? Enset: on glte: 4 extending e rest in the direction of the longitudinal axis of the hull ', and which is preferably housed in a hollow housing (3) provided at the lower end of the keel (2) and open downwards.
Le volet (4) est monté pivotant autour d'un axe vertical. The flap (4) is pivotally mounted about a vertical axis.
Dans le mode de réalisation représenté à la figure 1, le volet est monté par sa partie centrale sur un arbre vertical (5) actionné par un moteur de commande (6). In the embodiment shown in Figure 1, the flap is mounted by its central part on a vertical shaft (5) actuated by a control motor (6).
A la figure 2, on voit de nouveau une coque de bâteau (7) munie d'une quille (8) présentant à son extrémité inférieure un logement creux (9). In Figure 2, there is again seen a boat shell (7) provided with a keel (8) having at its lower end a hollow housing (9).
Dans ce logement, est disposé un volet de compensation de gite calé par sa partie frontale sur un arbre vertical (11) actionné par un moteur de commande (12). In this housing, there is a gite compensation flap wedged by its front part on a vertical shaft (11) actuated by a control motor (12).
Lorsque la coque selon l'invention prend sous l'action relative du vent une gîte plus ou moins prononcée, on actionne le moteur (6, 12) dans un sens ou dans un autre pour faire pivoter le volet (4, 10) qui s'écarte alors de l'axe longitudinal de la coque (1, 7). When the hull according to the invention takes on a more or less pronounced list under the relative action of the wind, the motor (6, 12) is actuated in one direction or another to rotate the flap (4, 10) which s 'then deviates from the longitudinal axis of the hull (1, 7).
A ce moment, le volet oppose une résistance à l'eau qui tend ainsi à compenser la gite de la coque. At this time, the flap opposes a resistance to water which thus tends to compensate for the hull gite.
Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits et représentés ici mais on peut y apporter de nombreuses modifications sans pour cela sortir du cadre de l'invention. Of course, the invention is not limited to the embodiments described and shown here, but many modifications can be made without departing from the scope of the invention.
