Abstract
Description
La pesante invention a pour objet une voilure pour bateau, et notamment une voile d'avant. The cumbersome invention relates to a sail sail, and in particular a head sail.
On sait que dans la navigation à voile, il faut pouvoir adapter la surface de voile du bateau à la force du vent. Le navigateur à cet effet dispose de plusieurs voiles qu'il peut gréer suivant la force dudit vent. Toutefois il n?est pas toujours aisé d'effectuer ce changement de voile, en sorte que certains bateaux sont équipés, notamment pour les voiles d'avant, d'un enrouleur permettant de réduire la surface de voile par enroulement. We know that in sailing, you have to be able to adapt the sail area of the boat to the force of the wind. The navigator for this purpose has several sails which he can set up according to the strength of said wind. However, it is not always easy to carry out this change of sail, so that certain boats are equipped, in particular for the forward sails, with a furling device making it possible to reduce the sail area by winding.
Néanmoins les enrouleurs présentent un inconvénient: en effet, lorsque le navigateur désire réduire la surface de voile de son bateau, c'est que le vent a forci, mais pour utiliser au maximum sa force, il est nécessaire que la voile soit la plus plate possible. However, the furlers have a drawback: in fact, when the navigator wishes to reduce the sail area of his boat, it is because the wind has increased, but to use his force as much as possible, the sail must be as flat as possible possible.
Or les voiles présentent un creux, et lorsque l'on enroule une voile, si ses extrémités s'enroulent parfaitement autour de l'enrouleur, sa partie centrale, qui comporte le creux, s'enroule en faisant des plis qui se défont lors de l'étarquage, laissant réapparaître le creux. However, the sails have a hollow, and when a sail is wound, if its ends are perfectly wrapped around the furler, its central part, which includes the hollow, is wound by making folds which come apart during stretching, letting the hollow reappear.
Divers dispositifs ont été proposés pour remédier à cet inconvénient. Ainsi le brevet français N" 2 567 097 décrit un dispositif permettant de rattraper le creux en rapprochant avant l'enroulement deux lèvres créées à la surface de la voile par un moyen de fermeture. Mais cette technique demande de nombreuses manipulations qui sont coûteuses en temps et en efforts, alors qu'il faut parfois effectuer cette manoeuvre rapidement et fréquemment. Various devices have been proposed to remedy this drawback. Thus, French patent No. 2,567,097 describes a device making it possible to make up for the hollow by bringing together before the winding two lips created on the surface of the sail by a closure means. But this technique requires numerous manipulations which are costly in time and in efforts, when it is sometimes necessary to perform this maneuver quickly and frequently.
La présente invention permet de pallier à ces divers inconvénients en proposant une voile adaptable sur n'importe quel enrouleur et permettant de réduire la surface de voile tout en réduisant le creux, en n'ayant à effectuer qu'une seule manoeuvre, l'enroulement. The present invention makes it possible to overcome these various drawbacks by proposing a sail which can be adapted to any reel and which makes it possible to reduce the sail surface while reducing the hollow, by having to carry out only one maneuver, the winding .
La voile objet de l'invention comporte à cet effet une ou plusieurs lattes forcées disposées chacune dans un fourreau parallèle au guindant, de sorte que lorsque la voile est enroulée jusqu'à ce qu'une latte soit prise dans l'enroulement, et donc que le fourreau la contenant ne soit plus apparent, cette latte plaquée contre l'enrouleur empêche le creux de se reformer lorsque la voile est étarquée. The sail object of the invention comprises for this purpose one or more forced slats each disposed in a sheath parallel to the luff, so that when the sail is wound until a batten is caught in the winding, and therefore that the sheath containing it is no longer visible, this slat pressed against the furler prevents the hollow from re-forming when the sail is stretched.
Les avantages et les caractéristiques de la présente invention ressortiront plus clairement de la description qui suit et qui se rapporte au dessin annexé, lequel en représente un mode de réalisation non limitatif. The advantages and characteristics of the present invention will emerge more clearly from the description which follows and which refers to the appended drawing, which represents a non-limiting embodiment thereof.

- la figure 3b représente une vue en coupe selon la ligne BB de la figure 2. - Figure 3b shows a sectional view along line BB of Figure 2.
Si on se réfère à la figure 1 on peut voir une voile 1 selon l'invention comportant le long de son guidant 10 un enrouleur 2. Cette voile 1 comporte des fourreaux 11, 12, 13 disposés parallèlement au guidant et espacés, destinés à recevoir des lattes 21, 22, 23 qui sont enfilées dans lesdits fourreaux par le bas, la fermeture s'effectuant de manière classique par des transfilages 15. If we refer to Figure 1 we can see a sail 1 according to the invention comprising along its guide 10 a reel 2. This sail 1 has sleeves 11, 12, 13 arranged parallel to the guide and spaced apart, intended to receive slats 21, 22, 23 which are threaded into said sheaths from the bottom, the closing being effected in a conventional manner by threading 15.
Si on se réfère à la figure 2 on peut voir que la voile 1 est enroulée sur l'enrouleur 2 jusqu'à ce que le premier fourreau, 11, contenant une latte 21 ait effectué un tour et qutil soit ainsi prisonnier de l'enroulement. If we refer to Figure 2 we can see that the sail 1 is wound on the reel 2 until the first sheath, 11, containing a slat 21 has made a turn and it is thus trapped in the winding .
Si on se réfère maintenant à la figure 3a on peut voir qu'aux extrémités de l'enrouleur 2 la voile est parfaitement enroulée autour dudit enrouleur 2. If we now refer to FIG. 3a, we can see that at the ends of the reel 2 the sail is perfectly wrapped around said reel 2.
Si on se réfère à la figure 3b on peut voir qu'au milieu de l'enrouleur 2 la voile, du fait de son creux 14, n'est pas enroulée serrée, mais que ledit creux 14 est prisonnier de l'enroulement et qu'il ne peut s'en échapper lors de l'étarquage, la latte 21 contenue dans le premier fourreau 11 constituant un obstacle longitudinal infranchissable. If we refer to Figure 3b we can see that in the middle of the winder 2 the sail, due to its hollow 14, is not wound tight, but that said hollow 14 is trapped in the winding and qu 'it cannot escape during the stretching, the slat 21 contained in the first sheath 11 constituting an insurmountable longitudinal obstacle.
Dans l'exemple illustré, la surface de voile peut être réduite de 25 % par un enroulement jusqu'à la première latte 21, de 45 % jusqu'à la deuxième latte 22, de 65 % jusqu'à la troisième latte 23, d'autres dispositions et réductions étant bien entendu possibles. In the example illustrated, the sail area can be reduced by 25% by winding up to the first batten 21, by 45% up to the second batten 22, by 65% until the third batten 23, d other arrangements and reductions are of course possible.
Il va de soi que la présente invention ne saurait être limitée à la description qui précède d'un de ses modes de réalisation, susceptible de subir certaines modifications sans pour autant sortir du cadre de l'invention. It goes without saying that the present invention cannot be limited to the foregoing description of one of its embodiments, capable of undergoing certain modifications without departing from the scope of the invention.
