Abstract

The trimaran external floats can be adjusted horizontally and vertically relative to the central shell. This increases the stability, performance and comfort of the boat according to the force and direction of the wind.The trimaran is constituted from a central shell (1) with two external floats (2). The floats are able to slide horizontally forwards or rearwards the length of the connecting arm (3). The connecting arm (3) is pivoted on the arm (4) which allows vertical adjustment. This provides tightening or spacing the floats relative to the central shell.

Description

DESCRIPTION
La présente invention concerne un dispositif de glissement verticaI et horizontal des flotteurs extérieurs d'run voilier type trimaran, par rappart à la coque centrale;
Sur les trimarans ou catamarans classiques, les coques sont fixes et donc ne disposent pas de réglages à ce niveau. L'équilibre et la stabilité du bateau s'en trouvent donc perturbes, en fonction de la force et de la direction du vent. Cela joue sur les performances du bateau.DESCRIPTION
The present invention relates to a vertical and horizontal sliding device for the external floats of a trimaran type sailboat, by comparison with the central hull;
On classic trimarans or catamarans, the hulls are fixed and therefore do not have adjustments at this level. The balance and stability of the boat are therefore disturbed, depending on the strength and direction of the wind. This plays on the performance of the boat.

Le dispositif, selon l'invention, permet d'augmenter considérablement l'équi libre et la stabilité du bateau. Ainsi ses performances sont olus importantes, le confort est ameliore et le déplacement du poids est moindre (rappel du trapèze)
Les dessins annexes illustrent l'application de l'invention et ne représentent qu'un exemple.The device according to the invention makes it possible to considerably increase the balance and the stability of the boat. Thus its performance is more important, comfort is improved and weight displacement is less (reminder of the trapezoid)
The accompanying drawings illustrate the application of the invention and represent only one example.

La figure 1 représente une vue en plan de l'application.Figure 1 shows a plan view of the application.

La figure 2 représent une vue arrière de l'invention.Figure 2 shows a rear view of the invention.

Et la figure 3, elle, une vue de cAté. And Figure 3, it, a side view.

En reférence à ces dessins, le dispositif comporte une coque centrale (1), deux skis ou flotteurs extérieurs coulissants (2), et deux bras de liaison articulés (3).Referring to these drawings, the device comprises a central shell (1), two sliding skis or external floats (2), and two articulated link arms (3).

(2) : flotteurs à glissement avant du arrière paralléles à la coque centrale1 soutenu par la partie (3) et glissant dans une cornière le long de cetle-ci. (2): front sliding floats aft parallel to the central hull1 supported by part (3) and sliding in an angle iron along the latter.

Les forces d'appui varient le long des flotteurs par rapport à la direction de la voile Le réglage des flotteurs effectué manuellement à l'aide de cables pris sur un "Winch" ou électriquement ou hydroliquement, permet d'amener le flotteur à l'endroit ob les forces d'appui sont les plus fortes, afim d'équilibrer la portance. The support forces vary along the floats relative to the direction of the sail. The adjustment of the floats carried out manually using cables taken from a "Winch" or electrically or hydrolically, makes it possible to bring the float to the place where the support forces are strongest, in order to balance the lift.

(3) : bras de liaison portants la partie (2) c'est: à dire les flotteurs,
fixés et articulés sur la partie (4).(3): link arms carrying part (2), that is to say the floats,
fixed and articulated on the part (4).

L1 articulation de la partie (3) sur la partie (4) permet de resserer les-flot-
teurs le long de Sa coque centrale. Ce réglage actionné manuellement, éléctriqué-
ment ou hydroliquement, augment la poussée des flotteurs sur l'eau. Cela amé
liore la stabilité du bateau et provoque le déjaugement de la coque centrale,
Ainsi nous obtenons une diminutiom du tirant d'eau, et le bateau glisse uni
quement sur ses flotteurs (dans certaines conditi-ons). L1 articulation of the part (3) on the part (4) allows to tighten the -flot-
along its central hull. This manually operated, electrically controlled
or hydrologically, increases the thrust of the floats on the water. That brings
improves the stability of the boat and causes the central hull to take off,
So we get a decrease in the draft, and the boat slides together
only on its floats (in certain conditions).

Le bateau, grâce à l'invention, peut porter un nombre de métres carrés de voile supérieur, ce qui augmente sa puissance, par comparaison à un bateau classique
de la même catégorie.The boat, thanks to the invention, can carry a greater number of square meters of sail, which increases its power, compared to a conventional boat.
of the same category.

Le dispositif, selon l'invention, est particulièrement destiné à un nouveau
type de bateau, quelque soit sa taille. The device according to the invention is particularly intended for a new
type of boat, whatever its size.
