Abstract

Device which offers the craft to which it is fitted novel characteristics such as jumping and handleability. It consists of a stationary structure 2 to the apex of which is articulated a sail or wing 1, the structure itself being secured to the craft. The manoeuvres take place with the aid of two settings: the first "hauling the sheets taut and close-hauling the sheets" of the sail takes place by adjusting the inclination of the bar 5 by means of a set of sheets; The second setting takes place by means of the rope 2 which makes it possible to control the inclination of the plane of the sail assembly with respect to the surface over which one is travelling.

Description

La pressente invention concerne un dispositif de gréement nobile qui de part sa géométrie permet, lorsqu'il est utilisé sur un catamaran de sport (voir aussi engin de terre), de lui adjoindre des capacités supplénentaires. The present invention relates to a mobile rigging device which, by virtue of its geometry, makes it possible, when used on a sport catamaran (see also land craft), to add additional capacities to it.

Une première de ces capacités pernet au cata2aran, lorsqu'il gite de présenter une surface de voile toujours perpendiculaire i l'axe du vent (fig.l),la voile (i)pouvant alors offrir un rendement optinal contrairenent à ce qu'il se passe habituellenent. A first of these capacities pernet to the cata2aran, when it gites to present a surface of sail always perpendicular to the axis of the wind (fig.l), the sail (i) being able then to offer an optimal yield contrary to what it usually happens.

Une deuxième de ces capacités rient de la nobilité de la voile (ou aile) selon deux degrés de liberté,qui peut-etre positionné de façon horizontale ou pas selon se que souhaite l'opérateur, offrant ainsi la possibilité å l'engin d'avancer,de planner ou de voler au-dessus de la surface sur laquelle il évolue. Cette possibilité etant largenent exploitable part les amateurs de saut de vague. A second of these capacities laughs at the nobility of the sail (or wing) according to two degrees of freedom, which can be positioned horizontally or not according to what the operator wishes, thus offering the possibility to the craft of advance, planner or fly over the surface on which it is moving. This possibility being widely exploitable by amateurs of wave jumping.

Selon une première configuration (fig; 4 et 5), l'aile ou la voile est articulée au sommet d'une structure pyramidale (6) rigide à base carrée. According to a first configuration (fig; 4 and 5), the wing or sail is articulated at the top of a rigid pyramidal structure (6) with a square base.

Structure qui de part ses propriétés d'indéfornabilités dans le sens de la torsion supprinent toute fatigue en torsion au niveau des vulnérables poutres de liaison des catamarans. Chaque tube formant une arrete de cette pyranide vient se fixer sur une coque.Structure which due to its properties of indeformability in the direction of torsion eliminates any fatigue in torsion at the level of the vulnerable connecting beams of the catamarans. Each tube forming a stop of this pyranide is fixed on a shell.

Selon une deuxième configuration (fig 1, 2 et 3), la forme pyramidale
est matérialisée par un mat que l'on nommera mateau (4) pour ne pas le
confondre avec les nats (lO),lequel est maintenu verticalement par un haubannage classique (3).According to a second configuration (fig 1, 2 and 3), the pyramidal shape
is materialized by a mat which we will call mateau (4) so as not to
confused with the nats (lO), which is held vertically by a conventional guy (3).

Selon une troisième configuration (fig. 7), le. nât (10) est maintenu en deux endroits par deux tubes (7) et (8) se croisant ou non, chacun d'entre eux étant fixé à sa base sur sa coque respective par une liaison rotule. According to a third configuration (fig. 7), the. nât (10) is held in two places by two tubes (7) and (8) crossing or not, each of them being fixed at its base on its respective shell by a ball joint.

Si voile il y a, la bôme(9) permettra de la tendre par l'intermédiaire de son point d'écoute. If there is a veil, the boom (9) will allow it to be stretched through its listening point.

La manoeuvre du gréement se fait a l'aide de deux réglages. The rigging is operated using two settings.

Le premier consiste à faire varier, de façon classique, l'angle que fait le plan de voilure avec l'axe du vent. Il se fait en réglant l'inclinaison de la tige arrière(5)
Le deuxième consiste à régler l'inclinaison du plan de voilure de façon à pouvoir choisir la direction de la force resultante qui s'applique sur la voile, selon qu'on veuille voler ou avancer. The first consists in varying, in a conventional manner, the angle made by the sail plane with the axis of the wind. It is done by adjusting the inclination of the rear rod (5)
The second is to adjust the inclination of the sail plane so that you can choose the direction of the resulting force that applies to the sail, depending on whether you want to fly or move forward.

Claims

REYENDICATIONS

i) Mobile rigging adaptable to any light, nautical or terrestrial machine allowing the operator to choose a dominant one from the two components of the velical thrust are the load-bearing and propulsive components, characterized in that the surface intended to capture the.

wind force has two degrees of freedom.

- And a second part which can be either a sail or a wing (l), articulated at the top of this structure and which can take all the positions offered by these two degrees of freedom.

2) Device according to the preceding claim characterized in that it is composed of - a first part (3) and (4) or (6) according to the configuration respectively (fig. I, 2 or 3) or (fig. 4 and 5), integral with the shells, which can, if the pyramidal structure is tubular, stiffen the general structure since using the non-deformability properties of the triangles forming this pyramid,

3) Device according to any one of the preceding claims, characterized in that the listening point of 1R sail is connected to the machine by means of a tube (5) whose length determines the angle of attack optimal of the sail or the wing compared to the wind so that the machine can plan in good conditions.

5) Device according to any one of the preceding claims, characterized in that the second, specific adjustment and this boat is effected by means of a rope (8) attached to each end of the forward mast (10).

4) Device according to any one of the preceding claims, characterized in that the adjustment of the sail in the usual direction (border, shock) is done by giving an inclination to the bar (5)

6) Device according to any one of the preceding claims, characterized in that the ease of adjustment (in the direction of the force.

physical) is due to the symmetries of the wing or sail with respect to the directions of height and width, and to the almost superimposition of the center of thrust and the point of attachment of the propulsion unit.

7) Device which, depending on the configuration (fig. 7) stiffens the mast, the latter being held at two different points thus making the balance of the sail more stable, and thus adding flexibility in the operation of the rigging.
