Abstract

The device has a foot of a mast slidingly articulated on a rail, where the mast slides on the rail by a chain or cable controlled by a winch. A gantry (3) guides and maintains the mast by a carriage sliding in the rail or on the gantry. The carriage is articulated with the mast for varying a mast/carriage angle. A shroud is installed in a horizontal spacer for reinforcing a rigidity of the gantry.

Description

La présente invention concerne un dispositif permettant d'augmenter les rapports poids/puissance et stabilité/puissance des bateaux à voile.
Les mats des bateaux à voile sont à l'heure actuelle fixes ou très peu mobiles en inclinaison à la gîte ou contre gîte. Tout est fait pour au contraire apporter de la rigidité et maintenir le plan de voilure vertical.
Les voiles subissent une poussée latérale dont les résultantes tendent à renverser le bateau (1 fig. 1) en enfonçant la partie sous le vent de la coque ou la coque sous le vent (2 fig. 1) et en soulevant par réaction la coque au vent (3 fig.
1) Ce principe de base a déjà causé de nombreux et célèbres naufrages.
Le dispositif selon l'invention permet de diminuer les risques de chavirages sans abaisser notablement la force de propulsion, tout en apportant un effet de soulagement par la limitation des forces résultantes verticales.
Il comporte en effet comme première caractéristique un pied de mât articulé coulissant sur tout ou partie de la largeur du bateau. Ensuite un portique qui guide et maintient le mât par l'intermédiaire d'un chariot articulé coulissant.
Le dispositif permet d'incliner le mât et la voilure au vent, ce qui a pour effet de diriger vers le haut la résultante de poussée vélique et de diminuer les forces tendant à chavirer le bateau.
La perte de surface active induite par l'inclinaison du mât varie de 2% à 10[deg] jusqu'à 18% à 35[deg], cette perte se compense aisément dans la hauteur d'autant qu'en déplaçant le centre de voilure vers le haut on déplace l'axe de soulèvement au vent ainsi que le poids de la partie de mâture faisant contre gîte, ce qui augmente l'effet recherché.
Le mât ne pouvant être haubané selon les techniques habituelles doit être soit maintenu par des haubans coulissants, soit pourvu de guignols ou alors structuré pour tenir sans ces renforts.
Un étai reste possible en l'arrimant sur une patte d'oie calculée pour correspondre au centre de rotation (7 fig. 3) du mât.
Des étais rigides peuvent maintenir le portique en position et un guignol avant compenser la traction vers l'arrière de la voile et de l'écoute.
Les dessins annexés illustrent l'invention et ses principes.
La figure 1 montre le principe des forces appliquées par le vent sur la voilure (1 fig. 1) et ses composantes verticales (2 et 3 fig. 1). La figure 2 schématise les mêmes forces appliquées par le vent sur la voilure (1 fig. 2) et ses composantes verticales (2 et 3 fig. 2). La figure 3 montre le dispositif dans les trois positions extrêmes.
En référence à ces dessins le dispositif comporte un pied de mât articulé et coulissant (5 fig. 3) sur un rail (4 fig. 3) dont le coulissement peut être obtenu par des palans à corde ou par une chaîne ou câble commandé par treuil.
Un portique (3 fig. 3) assure le maintien et le guidage du mât en route et pendant l'inclinaison. La courbe de la partie haute du portique correspond à une distance constante entre le rail de pied de mât et une hauteur définie selon la largeur de coulissement disponible et l'angle d'inclinaison recherché, ce, en faisant varier l'angle d'inclinaison proportionnellement au déplacement du pied de mât sur son rail. Des haubans en diagonale (8 fig.1) en une entretoise horizontale (9 fig. 1) renforcent la rigidité du portique.
Le mât est solidarisé avec le portique par un chariot (6 fig.3) coulissant dans un rail ou sur le portique. Le chariot est articulé dans sa liaison avec le mât pour permettre la variation d'angle mât/chariot au cours du passage d'un coté à l'autre.
Le dispositif selon l'invention est particulièrement destiné aux bateaux multicoques mais s'adapte aux monocoques sous conditions de largeur suffisante pour atteindre un angle suffisant pour être efficace.
The present invention relates to a device for increasing the weight / power and stability / power ratios of sailing boats.
The masts of sailing boats are currently fixed or not very mobile in inclination at the heel or against heel. Everything is done to bring stiffness and keep the sail plan vertical.
The sails undergo a lateral thrust, the results of which tend to overturn the boat (1 fig. 1) by pushing the leeward part of the hull or the leeward hull (2 fig. 1) and lifting the hull by reaction wind (3 fig.
1) This basic principle has already caused many famous shipwrecks.
The device according to the invention makes it possible to reduce the risks of capsizing without appreciably lowering the propelling force, while bringing a relieving effect by limiting the resulting vertical forces.
As a first characteristic, it comprises an articulated mast foot sliding over all or part of the width of the boat. Then a gantry which guides and maintains the mast by means of a sliding articulated carriage.
The device makes it possible to tilt the mast and the sail to the wind, which has the effect of directing upwards the result of the thrust and reducing the forces tending to capsize the boat.
The loss of active surface induced by the inclination of the mast varies from 2% at 10 [deg] up to 18% at 35 [deg], this loss is easily compensated in height as much as by moving the center of wing up, the lifting axis is moved in the wind as well as the weight of the part of the mast making against the heel, which increases the desired effect.
The mast which cannot be guyed according to the usual techniques must either be maintained by sliding guy lines, or provided with horns or then structured to hold without these reinforcements.
A forestay remains possible by securing it on a crow's feet calculated to correspond to the center of rotation (7 fig. 3) of the mast.
Rigid stays can keep the gantry in position and a horn before compensating for the rearward pull of the sail and the sheet.
The accompanying drawings illustrate the invention and its principles.
Figure 1 shows the principle of the forces applied by the wind on the wing (1 fig. 1) and its vertical components (2 and 3 fig. 1). Figure 2 shows schematically the same forces applied by the wind on the airfoil (1 fig. 2) and its vertical components (2 and 3 fig. 2). Figure 3 shows the device in the three extreme positions.
With reference to these drawings, the device comprises an articulated and sliding mast foot (5 fig. 3) on a rail (4 fig. 3), the sliding of which can be obtained by rope hoists or by a chain or cable controlled by winch. .
A gantry (3 fig. 3) maintains and guides the mast while underway and during tilting. The curve of the upper part of the gantry corresponds to a constant distance between the mast foot rail and a height defined according to the available sliding width and the desired inclination angle, this by varying the inclination angle in proportion to the movement of the mast foot on its rail. Diagonal shrouds (8 fig. 1) in a horizontal spacer (9 fig. 1) reinforce the rigidity of the gantry.
The mast is secured to the gantry by a carriage (6 fig.3) sliding in a rail or on the gantry. The carriage is articulated in its connection with the mast to allow the mast / carriage angle variation during the passage from one side to the other.
The device according to the invention is particularly intended for multihull boats but adapts to monohulls under conditions of sufficient width to reach a sufficient angle to be effective.
