Abstract

The invention concerns a pendular nautical craft whereof the passengers are overhead in a nacelle travelling above the water surface. It consists of: a floatable hull (1) equipped with a control system; an arm (2) pivoting on the hull; a nacelle (3) attached to the arm on its free part, and wherein are seated the passengers and the set of controls; a kite-like sail (6) fixed to the nacelle (3). The traction on the sail (6) exerted by the wind lifts the nacelle (3) with its passengers above the water and provides, via the arm (2), a propelling force to the hull (1). The piloting controls of the craft, installed in the nacelle, are used to manoeuvre the hull control system, the sail activity, to modify the craft displacement speed and generally to adapt to sailing conditions.

Description

ENGIN NAUTIQUE PROPULSE PAR LE VENT WIND-PROPELLING NAUTICAL MACHINE
La présente invention concerne un engin nautique pendulaire tracté par la force du vent caractérisé en ce que les passagers sont suspendus dans une nacelle évoluant au dessus de l'eau.The present invention relates to a pendular nautical vehicle towed by the force of the wind characterized in that the passengers are suspended in a nacelle moving above the water.
Les passagers, installés dans la nacelle, disposent des différentes commandes qui permettent de gérer l'évolution de l'engin, la direction du déplacement et sa vitesse.The passengers, installed in the nacelle, have different controls which allow to manage the evolution of the machine, the direction of movement and its speed.
Cet engin est inspiré du dériveur pour ce qui est de la position dite 'en rappel', du ski nautique soulevé par une aile de parapente et du suif tracté par un cerf-volant. Son utilisation se distingue par la maîtrise totale de son évolution de l'engin par les passagers. Leur position instable et pendulaire au dessus de l'eau, affranchie des effets des chocs de l'eau sur la coque, la maniabilité, procurent de nouvelles sensations.This machine is inspired by the dinghy in terms of the so-called 'abseiling' position, water skiing lifted by a paraglider wing and tallow towed by a kite. Its use is distinguished by the total control of its evolution of the craft by the passengers. Their unstable and pendular position above the water, freed from the effects of water impacts on the hull, the maneuverability, provide new sensations.
L'engin est constitué d'une coque équipée de gouvernes de direction et éventuellement de profondeur, d'un bras solidaire de la coque par une articulation positionnée sur sa partie centrale et son plan de symétrie longitudinal. Sur l'extrémité du bras libre de la coque prennent place plusieurs passagers dans une nacelle suspendue,.The machine consists of a hull fitted with rudders and possibly of depth, of an arm secured to the hull by an articulation positioned on its central part and its longitudinal plane of symmetry. Several passengers sit on the end of the free arm of the hull in a suspended basket.
L'engin est tracté par une ou plusieurs voilures soumises à la force du vent reliées au bras par des moyens souples et réglables,. La coque, libre de tout passager, a essentiellement une fonction de contact avec le milieu aquatique, et impose la direction du déplacement et résiste à la dérive de l'engin.The machine is towed by one or more blades subjected to the force of the wind connected to the arm by flexible and adjustable means. The hull, free of any passenger, essentially has a function of contact with the aquatic environment, and imposes the direction of movement and resists the drift of the craft.
La coque peut avoir une forme adaptée au type de navigation souhaitée (course, raid ,mer, lac ..), longue et fine pouvant, du fait de sa densité, de façon momentanée, être totalement immergée sous l'effet des forces transmises par le bras, soit de forme aplatie de type surf évoluant en surface comme un patin.The hull can have a shape adapted to the type of navigation desired (race, raid, sea, lake, etc.), long and fine which, due to its density, momentarily, can be completely submerged under the effect of the forces transmitted by the arm, either flattened surf type evolving on the surface like a skate.
La ou les voilures ou structures peuvent être un ballon plus léger que l'air, un cerf volant, une aile de parapente, une voilure spécifique. Le(s) gouvernail(s) et les voilures sont commandés mécaniquement par le(s) pilote(s) installé(s) dans la nacelle.The wing (s) or structure may be a lighter-than-air balloon, a kite, a paraglider wing, a specific wing. The rudder (s) and the sails are mechanically controlled by the pilot (s) installed in the nacelle.

Le cas de l'engin illustré dans les dessins comprend :The case of the machine illustrated in the drawings includes:
- une coque (1) de forme générale allongée et fine comportant un plan de symétrie longitudinale (A) avec une face supérieure et une face inférieure immergée en position de repos, sans dérive, la forme de la coque (1) faisant office. Cette coque est équipée d'un gouvernail (4) de direction orientable, commandé mécaniquement par câbles par le(s) passager(s).- A shell (1) of generally elongated and fine shape comprising a plane of longitudinal symmetry (A) with an upper face and a lower face immersed in the rest position, without drift, the shape of the shell (1) acting. This hull is fitted with a steerable rudder (4), mechanically controlled by cables by the passenger (s).
- un bras (2) possédant un axe de rotation (D) longitudinal, solidaire de la coque (1) par une articulation (14) positionnée sur la face supérieure de la dite coque, dans son plan de symétrie (A), en sa partie centrale et de façon réglable. Le bras (2) pivote sur son axe de rotation (D) sur 360°, et par rapport à la dite coque, d'arrière en avant dans le plan de symétrie (A) longitudinal de la coque (1) selon un angle ( ) maximal, imposant en permanence au bras (2) une position sur l' arrière de la coque (1).- An arm (2) having a longitudinal axis of rotation (D), integral with the shell (1) by an articulation (14) positioned on the upper face of said shell, in its plane of symmetry (A), in its central part and adjustable. The arm (2) pivots on its axis of rotation (D) through 360 °, and by with respect to said hull, from rear to front in the longitudinal plane of symmetry (A) of the hull (1) at a maximum angle (), permanently imposing on the arm (2) a position on the rear of the hull (1).
- une nacelle (3) suspendue par une charnière pivotante à une potence (15) solidaire du bras (2) dans sa partie libre de la coque (3), dans laquelle prennent place le(s) passager(s) maintenus par effet pendulaire en position assise verticale. La position de la nacelle sur le bras est réglable pour modifier le bras de levier exercé par la nacelle sur le bras.- a nacelle (3) suspended by a pivoting hinge from a bracket (15) secured to the arm (2) in its free part of the shell (3), in which the passenger (s) held by pendulum effect take place in a vertical sitting position. The position of the nacelle on the arm is adjustable to modify the lever arm exerted by the nacelle on the arm.
- une voilure (6), de type cerf-volant de traction à deux brins, insubmersible, décolable de l'eau, symétrique en activité, sans action différentielle sur les brins, suivant un plan vertical (B) dans le même plan vertical que celui contenant l'axe du vent (C ). L'activité de la voilure est commandée à partir de la nacelle par deux câbles (10).- an airfoil (6), of the two-strand traction kite type, unsinkable, detachable from water, symmetrical in activity, without differential action on the strands, in a vertical plane (B) in the same vertical plane as the one containing the wind axis (C). The wing activity is controlled from the nacelle by two cables (10).
- un dispositif de flottaison (5) solidaire de la nacelle (3) et de sa potence (15). Le dispositif de flottaison (5) rend la dite nacelle insubmersible avec ou sans ses passagers. Il offre à l'arrêt une assise suffisamment stable pour que les passagers puissent monter et descendre dans la dite nacelle sans chavirer.- a flotation device (5) integral with the nacelle (3) and its stem (15). The flotation device (5) makes said pod unsinkable with or without its passengers. When stationary, it offers a sufficiently stable seat so that passengers can get on and off in the so-called gondola without capsizing.
Les figures 1 et 2 nous montre un engin nautique en fonctionnement dans une allure dite 'au portant' respectivement en vue de coté et vue de dessus la voilure (6) est déployée au-dessus de l'eau, la nacelle (3) est soulevée.Figures 1 and 2 shows us a nautical craft in operation in a so-called 'downwind' pace respectively in side view and top view the wing (6) is deployed above the water, the nacelle (3) is raised.
La figure 3 montre les différentes rotations possibles du bras. Le bras (2) lorsque l'engin est en activité est généralement incliné au dessus de l'eau. Le bras en cours d'évolution est situé dans le plan de symétrie (A) de la coque (1) la dite coque est alors sur un de ses cotés comme le montre les figures 1 ,2 4 et 5.Figure 3 shows the different possible rotations of the arm. The arm (2) when the machine is active is generally inclined above the water. The evolving arm is located in the plane of symmetry (A) of the shell (1), the said shell is then on one of its sides as shown in FIGS. 1, 2 4 and 5.
La voilure prend automatiquement position au-dessus de l'eau de telle sorte que la nacelle (3) est soulevée et maintenue en hauteur. Les brins de la voilure sont fixés à deux câbles (10) commandés depuis la nacelle (3) et circulant dans un anneau (12) fixé au sommet de la potence du bras (2) à proximité de la charnière qui soutient la nacelle (3).The wing automatically takes up position above the water so that the nacelle (3) is lifted and kept high. The blade strands are fixed to two cables (10) controlled from the nacelle (3) and circulating in a ring (12) fixed to the top of the arm stem (2) near the hinge which supports the nacelle (3 ).
La voilure (6) a une hauteur réglable à partir de la nacelle (3), elle peut être 'active' ou 'inactive'. Pour la rendre 'active' il suffit de libérer les câbles de commande (10) de la voilure (6) jusqu'à une certaine position, et de tirer sur ces câbles (10) grâce à un dispositif d'enroulement actionné par pédalier ou winch pour en régler la distance, la fermer et la rendre 'inactive'.The airfoil (6) has an adjustable height from the nacelle (3), it can be 'active' or 'inactive'. To make it 'active' it suffices to release the control cables (10) from the airfoil (6) to a certain position, and to pull on these cables (10) thanks to a winding device actuated by pedal or winch to adjust the distance, close it and make it 'inactive'.
Pour modifier le positionnement de la voilure (6) par rapport à l'axe du vent (C) l'on agit à partir de la nacelle et par traction différentielle sur les câbles de commande (10) de la voilure (6) grâce à une ou plusieurs pédales ou manettes. Ceci a pour effet de faire pivoter la voilure (6) sur elle même et de la déplacer par rapport au plan vertical dans lequel se trouve l'axe du vent (C ) et permet alors à l'engin de naviguer sous une allure dite 'au prés' comme illustré sur les figures 4 et 5.To modify the positioning of the airfoil (6) relative to the wind axis (C), one acts from the nacelle and by differential traction on the control cables (10) of the airfoil (6) thanks to one or more pedals or joysticks. This has the effect of rotating the canopy (6) on itself and of moving it relative to the vertical plane in which the wind axis is located (C) and then allows the craft to navigate under a so-called 'gait' near as illustrated in figures 4 and 5.
Suivant le modèle, la nacelle (3) peut héberger une ou plusieurs personnes. Les commandes de pilotage peuvent être constituées de volant(s), palonnier(s), guidon(s), winch(es), manette(s) pour manoeuvrer le(s) gouvernail(s) (4), l'activité de la voilure (6), la position de la nacelle (3) sur le bras (2), l'allure de déplacement de l'engin et le réglage de l'angle ( ).Depending on the model, the basket (3) can accommodate one or more people. The steering controls can consist of steering wheel (s), spreader (s), handlebars (s), winch (es), joystick (s) to operate the rudder (s) (4), the activity of the airfoil (6), the position of the nacelle (3) on the arm (2), the speed of movement of the machine and the adjustment of the angle ().
Pour limiter les effets produits par les incidents de navigation (risées, vagues,..) qui pourrait faire basculer la nacelle (3) par dessus la coque (1), l'engin est équipé d'un dispositif (7) de limitation de la hauteur de la nacelle (3) au dessus de l'eau.To limit the effects produced by navigation incidents (risings, waves, etc.) which could cause the nacelle (3) to tip over the hull (1), the machine is equipped with a device (7) for limiting the height of the nacelle (3) above the water.
La figure 6 montre le dispositif (7) de limitation de hauteur de la nacelle au dessus de l'eau en position inactive, la hauteur de la nacelle (3) au-dessus de l'eau n'étant pas suffisante. La figure 7 montre le même dispositif actif.Figure 6 shows the device (7) for limiting the height of the nacelle above the water in the inactive position, the height of the nacelle (3) above the water is not sufficient. Figure 7 shows the same active device.
Ce dispositif est constitué d'un câble (8) (ou cordage, ou bout..) d'une longueur adaptable suivant la limitation souhaitée. A chaque extrémité de ce câble (8) est fixé un anneau (9). Le câble (8) est accroché à ime cadène (11) fixée au bras (2) dans sa partie basse. Les câbles (10) de commande de la voilure (6) circulent dans les anneaux (9). Le dispositif (7) se met en activité lorsque la nacelle (3) arrive à une certaine hauteur au-dessus de l'eau déterminée par la position de la cadène (11) sur le bras (2) et la longueur du câble (8). Ce dispositif (7) de lhnitation de la hauteur de la nacelle (3) modifie automatiquement le bras de levier exercé par la voilure (6) sur le bras (2). Ce dispositif (7) peut être actif quelle que soit l'allure de l'engin comme illustré en figures 3 et 4 sous une allure 'au prés' respectivement en vue de dessus et de coté : le plan (B) de symétrie de la voilure (6) a pivoté, le dispositif (7) de limitation de hauteur de la nacelle s'est adapté à cette nouvelle situation, A l'arrêt, comme le montre la figure 8, les câbles (10) de commande de la voilure (6) sont tirés dans la nacelle (3). Ces derniers et les brins de soutien de la voilure et la voilure (6) elle-même, sont enserrés dans les anneaux (9) du dispositif (7) de limitation de hauteur de la nacelle (3) et celui (12) du sommet de la potence (15). La voilure (6) est alors fermée, sa surface au vent est telle qu'elle ne peut plus procurer de force suffisante pour soulever la nacelle (3) et tracter l'engin.This device consists of a cable (8) (or rope, or end ..) of an adaptable length according to the desired limitation. At each end of this cable (8) is fixed a ring (9). The cable (8) is attached to a padlock (11) fixed to the arm (2) in its lower part. The airfoil control cables (10) (6) circulate in the rings (9). The device (7) is activated when the nacelle (3) arrives at a certain height above the water determined by the position of the padlock (11) on the arm (2) and the length of the cable (8 ). This device (7) for the height of the nacelle (3) automatically modifies the lever arm exerted by the blade (6) on the arm (2). This device (7) can be active whatever the shape of the machine as illustrated in FIGS. 3 and 4 under a look “in the meadows” respectively from above and from the side: the plane (B) of symmetry of the wing (6) has pivoted, the device (7) for limiting the height of the nacelle has adapted to this new situation, when stationary, as shown in FIG. 8, the cables (10) for controlling the wing (6) are pulled into the nacelle (3). These and the support strands of the airfoil and the airfoil (6) itself, are enclosed in the rings (9) of the device (7) for limiting the height of the nacelle (3) and that (12) of the top. of the gallows (15). The airfoil (6) is then closed, its windward surface is such that it can no longer provide sufficient force to lift the nacelle (3) and tow the machine.
En relâchant à partir de la nacelle (3) les câbles (10) de commande de la voilure, la voilure (6) ainsi que les brins de la voilure se libèrent des anneaux (9) et (12), la voilure (6) s'ouvre jusqu'à son ouverture complète, devient alors totalement 'active' et prend une position au-dessus de l'eau détenninée par la longueur libérée des câbles (10).By releasing from the nacelle (3) the cables (10) for controlling the airfoil, the airfoil (6) and the strands of the airfoil are released from the rings (9) and (12), the airfoil (6) opens up to its full opening, then becomes completely 'active' and takes up a position above the water determined by the length released from the cables (10).
Les figures 9 à 12 illustre une foπne de coque (1) spécifique de cet engin.Figures 9 to 12 illustrates a hull foπne (1) specific to this machine.

La figure 17 montre im schéma du dispositif de réglage de la position de la nacelle sur le bras. Ce réglage peut être effectué par les passagers eux même directement à partir de la nacelle grâce à un dispositif mécanique d'enroulement du câble (23). Le dispositif de réglage de la position de la nacelle sur le bras est constitué d'un palan (21) à plusieurs poulies. Ce palan (21) est fixé en sommet de bras (2) par un dispositif démontable et à son autre extrémité et aussi de façon démontable à un galet (22) pouvant circuler sur la potence (15).FIG. 17 shows a diagram of the device for adjusting the position of the nacelle on the arm. This adjustment can be made by the passengers themselves directly from the nacelle by means of a mechanical cable winding device (23). The device for adjusting the position of the nacelle on the arm consists of a hoist (21) with several pulleys. This hoist (21) is fixed at the top of the arm (2) by a removable device and at its other end and also in a removable manner to a roller (22) which can circulate on the bracket (15).
La figure 18 montre un schéma partiel de l'engin équipé d'un dispositif de réglage de l'angle ( ), constitué d'un câble (26) de longueur réglable par les passagers avec des moyens mécaniques d'enroulement. Ce câble est fixé à une cadène (24) située sur la coque et une autre (28) située sur le bras.Figure 18 shows a partial diagram of the machine equipped with an angle adjustment device (), consisting of a cable (26) of length adjustable by the passengers with mechanical winding means. This cable is fixed to a padlock (24) located on the hull and another (28) located on the arm.
