Abstract

Craft with a sail the wing structure of which is a wing fixed to the top of a mast by an articulation and that the user holds and manipulates through the use of a handlebar located at the end of a handle perpendicular to the wing. The hull of the craft is equipped either with underwater fins (2) or with skis connected to the hull by dagger boards (3) such that the hull comes out of the water with speed. In operation, equilibrium of the craft is ensured by the user in a similar fashion to the sail of a sail board. Applications: sailing craft, beach sport and leisure pursuits.

Description

Le brevet principal (nO 88 11785 du 9 Sept. 88) décrit un engin à voile dont la voilure est une aile fixée au sommet d'un mât par une articulation et que l'on tient par l'intermédiaire d'un manche perpendiculaire à l'aile, et la presente addition décrit des variantes de cet engin dont les coques sont spécialement équipées pour augmenter la vitesse. The main patent (No. 88 11785 of 9 Sept. 88) describes a sailing machine, the blade of which is a wing fixed to the top of a mast by an articulation and which is held by means of a handle perpendicular to the wing, and the present addition describes variants of this machine whose hulls are specially equipped to increase speed.

Cet équipement consiste en des ailes ou des skis fixés sous la ou les coques afin que l'engin, s'appuyant sur ces éléments, s'enfonce moins dans l'eau, les coques pouvant aller, avec la vitesse, jusqu'à ne plus toucher l'eau
Selon l'une des variantes montrée aux figures 1 et 2, la coque (1) (ou les coques) est équipée d'une ou plusieurs ailes (2) sous-marines sensiblement parallèles au dessus de la coque disposées sous celle-ci transversalement par rapport à la coque et reliées à elle par des dérives (3) sensiblement verticales ou obliques.This equipment consists of wings or skis fixed under the hull (s) so that the machine, leaning on these elements, sinks less in the water, the hulls being able to go, with speed, up to more touch the water
According to one of the variants shown in Figures 1 and 2, the hull (1) (or the hulls) is equipped with one or more underwater wings (2) substantially parallel to the top of the hull arranged under the latter transversely relative to the hull and connected to it by drifts (3) substantially vertical or oblique.

Le plan de portance de ces ailes sous-marines est orienté légèrement à cabrer afin que le déplacement horizontal de la coque dans l'eau crée une force de portance vers le haut. The lift plane of these underwater wings is oriented slightly to nose up so that the horizontal displacement of the hull in the water creates a lift force upwards.

Selon une autre variante montrée aux figures 3 et 4, la coque (1) (ou chaque coque, s'il y en a plusieurs) est équipée d'un ski (4) disposé sous la coque longitudinalement et relié à la coque (1) par des dérives (5) et/ou ailerons (6) sensiblement verticaux. L'avant du ski est cambré vers le haut; I'extrémité avant de la spatule (6) peut rejoindre l'avant de la coque. According to another variant shown in Figures 3 and 4, the hull (1) (or each hull, if there are several) is equipped with a ski (4) disposed under the hull longitudinally and connected to the hull (1 ) by substantially vertical fins (5) and / or fins (6). The front of the ski is arched up; The front end of the tip (6) can join the front of the hull.

Selon une autre variante montrée à la figure 5, la coque est équipée d'une aile (7) en forme de V, formée de 2 dérives obliques se rejoignant sous la coque. According to another variant shown in FIG. 5, the hull is equipped with a wing (7) in the shape of a V, formed by 2 oblique daggerboards joining under the hull.

Avec la vitesse, les coques de ces bateaux sortent de l'eau et l'équilibre des engins est assuré par l'utilisateur en bordant plus ou moins la voile. With speed, the hulls of these boats come out of the water and the balance of the machines is ensured by the user by more or less lining the sail.

Selon une variante montrée à la figure 6, I'engin n'a pas de coques; la base du mât (8) est fixée à une structure (9) de forme sensiblement triangulaire ou semi-circulaire comportant d'une part 2 roues (10) à axe transversal commun et d'autre part, une "roue folle" (lui), c'est à dire une roue dont l'axe horizontal s'oriente librement. Cet engin est guidé par l'utilisateur à l'aide du guidon (12) situé au bout du manche de commande de l'aile, en faisanf tourner l'aile autour de ce manche pris comme axe de rotation, afin de déplacer le centre de poussée de la voile devant ou derrière l'axe transversal des roues (10). According to a variant shown in Figure 6, the machine has no shells; the base of the mast (8) is fixed to a structure (9) of substantially triangular or semi-circular shape comprising on the one hand 2 wheels (10) with common transverse axis and on the other hand, a "mad wheel" (it ), that is to say a wheel whose horizontal axis turns freely. This machine is guided by the user using the handlebars (12) located at the end of the wing control stick, by turning the wing around this stick taken as the axis of rotation, in order to move the center sail thrust in front of or behind the transverse axis of the wheels (10).

Applications: Voiliers et engins de plage. Applications: Sailboats and beach machines.

Claims

2. Sailing machine according to claim 1 of the main patent characterized in that the hull, or each hull, if there are several, is equipped with a ski (4) disposed under the hull longitudinally and connected to the hull (1) by substantially vertical drifts (5) and / or fins (6), the front end of the tip (6) of the ski being able to join the front of the hull.

3. Sailing machine according to claim 1 of the main patent characterized in that the hull is equipped with a wing (7) in the form of V, formed of 2 oblique daggerboards joining under the hull.
