Craft having a wing (1), symmetrical according to a plane, connected at the top of a mast (2) by means of a flexible joint or a swivel and which is handled by means of a control bar (5) perpendicular to the wing under the latter, and comprising at its base a handle bar (7). The rotation of the handle bar allows to steer a boat having a center board (8). The mast is either fixed or movable rotating about an axis directed according to the longitudinal axis of the craft. The wing is comprised of two half wings which are not in the same plane. The wing may consist of a sailcloth stretched on an articulated armature which may be folded on unfolded like a parasol so as to bring together the sailcloth within a small volume about the handle (6) which is used to manoeuvre the sail, or on the contrary to stretch the sail cloth close to a plane perpendicular to the handle (5). The armature has essentially 3 bars (18, 19 and 20) and is kept open by means of a system including 3 small bars (24, 25 and 26) of which one end slides along the handle (5). The cloth (28) at the vicinity of the leading edge of the sail may be cambered by means of a lath (29) which bends at the opening. Applications: beach craft, sport and leisure boats, sail bicycle, delta-plane.

Description

ENGIN A VOILURE EN AILE FIXEE ARTICULEE AU SOMMET D'UN MAT Le présent brevet présente un bateau ou engin à voile dont la voilure est caractérisée par sa forme, sa fixation et son utilisation. FIXED WING VEHICLE ARTICULATED AT THE TOP OF A MAST This patent presents a boat or sailing machine whose sail is characterized by its shape, its fixing and its use.

La forme de la voilure est celle d'une aile symétrique selon un plan; elle peut être proche, en ce qui concerne sa géométrie ou sa technologie, de celle d'un avion, d'un delta-plane ou d'un ultra-léger-motorisé (ULM).The shape of the wing is that of a wing symmetrical according to a plane; it can be close, as regards its geometry or its technology, to that of an airplane, a delta-plane or an ultra-light-motorized (ULM).

Une aile de ce type est illustrée aux figures 1 , 2 et 3 équipant un petit catamaran. L'aile (1) est reliée au sommet d'un mât (2) fixe par rapport aux coques (3) (éventuellement à la coque si elle est unique) ou mobile en rotation autour d'un axe, l'aile étant fixée par l'intermédiaire d'une pièce (4) servant d'articulation, pouvant être une rotule ou une pièce souple. Le point de fixation à l'aile se situe sous celle-ci dans son plan de symétrie. Pour être orientée, cette aile peut être équipée d'une tige (5), dite tige ou bar¬ re de commande ou manche, approximativement perpendiculaire au plan de portance moyen et située dans le plan de symétrie de l'aile sous celle-ci. Cette tige (5) peut être éventuellement renforcée par une autre tige et/ou des câbles (6) ou filins. Elle peut être articulée pour se plier sous l'aile. Sur un petit bateau ou un engin de plage à roues, l'aile est tenue et manoeu- vrée au moyen d'un guidon (7), d'un volant ou de poignées situés à l'extrémi¬ té basse de la tige (5) de commande. Au repos, le guidon est accroché vers le bas du mât, éventuellement par un élastique, de sorte que la tige (5) de commande soit sensiblement verticale et que donc l'aile soit maintenue approximativement horizontale au dessus du sommet du mât.A wing of this type is illustrated in Figures 1, 2 and 3 fitted to a small catamaran. The wing (1) is connected to the top of a mast (2) fixed relative to the hulls (3) (possibly to the hull if it is unique) or mobile in rotation around an axis, the wing being fixed by means of a part (4) serving as an articulation, which may be a ball joint or a flexible part. The point of attachment to the wing is located below it in its plane of symmetry. To be oriented, this wing can be equipped with a rod (5), said rod or control rod or handle, approximately perpendicular to the mean lift plane and situated in the plane of symmetry of the wing under the latter. . This rod (5) can possibly be reinforced by another rod and / or cables (6) or ropes. It can be hinged to fold under the wing. On a small boat or wheeled beach machine, the wing is held and maneuvered by means of a handlebar (7), a steering wheel or handles located at the lower end of the rod ( 5) order. At rest, the handlebars are hung down the mast, possibly by an elastic band, so that the control rod (5) is substantially vertical and therefore the wing is held approximately horizontal above the top of the mast.

Pour utiliser la voilure, on oriente l'aile de sorte que son plan de symétrie soit sensiblement vertical et parallèle à la direction du vent, le bord d'attaque de l'aile étant dirigé vers le vent, puis on bascule la tige de commande vers le haut et vers l'arrière du bateau jusqu'à ce que l'aile soit suffisamment verti¬ cale; pour border la voile, on amène la tige (5) vers le vent. Pour équilibrer la force du vent, l'utilisateur a intérêt à se pencher en arrière en se tenant au guidon de commande (7).To use the airfoil, the wing is oriented so that its plane of symmetry is substantially vertical and parallel to the wind direction, the leading edge of the wing being directed towards the wind, then the control rod is tilted. upwardly and rearwardly of the boat until the wing is sufficiently verti¬ wedge; to border the sail, the rod (5) is brought upwind. To balance the force of the wind, it is in the user's interest to lean back while holding onto the control handlebar (7).

Selon une variante, l'aile est constituée de 2 demi-ailes, qui ne sont pas dans un même plan mais dans 2 plans faisant entre eux un angle d'au moins 15° et généralement proche de 40°. Ainsi, vues de l'avant, les 2 demi-ailes forment un angle alpha d'environ 140° comme montré à la figure 4. Pour son utilisation, l'aile est mise dans une position proche de celle présen¬ tée à la figure 4 où la demi-aile supérieure est verticale, la demi-aile inférieure faisant alors un angle béta de 40° environ avec la verticale. Ainsi, lorsque le vent, supposé horizontal, souffle dans cette voile, la compo¬ sante horizontale de la force donnée par l'aile supérieure est plus grande que la composante horizontale de la force donnée par l'aile inférieure. Le centre de poussée horizontale de la voile se trouve alors en un point (par exemple C) situé au dessus du point de rotation (4) situé au sommet du mât.According to a variant, the wing consists of 2 half-wings, which are not in the same plane but in 2 planes forming between them an angle of at least 15 ° and generally close to 40 °. Thus, seen from the front, the 2 half-wings form an alpha angle of approximately 140 ° as shown in FIG. 4. For its use, the wing is placed in a position close to that presented in FIG. 4 where the upper half-wing is vertical, the lower half-wing then making a beta angle of approximately 40 ° with the vertical. Thus, when the wind, assumed to be horizontal, blows in this sail, the horizontal component of the force given by the upper wing is greater than the horizontal component of the force given by the lower wing. The center of horizontal thrust of the sail is then at a point (for example C) located above the point of rotation (4) located at the top of the mast.

On peut donc, si l'on fait tourner la voile autour de la tige (5) de commande, prise comme axe de rotation, déplacer le centre de poussée vers l'avant ou l'arrière du bateau.It is therefore possible, if the sail is rotated around the control rod (5), taken as the axis of rotation, to move the center of thrust towards the front or the rear of the boat.

Ainsi, il est possible de diriger un bateau ayant au moins une dérive (8) en utilisant le guidon (7) pour faire tourner la tige (5) sur elle-même dans un sens ou dans l'autre sens, car on remonte au vent (on loffe) lorsqu'on met le centre de poussée de la voile derrière le centre de réaction de la dérive (sensi- blement le barycentre de la dérive), et on descend sous le vent (on abat) lors¬ qu'on met le centre de poussée de la voile devant le centre de réaction de la dérive.Thus, it is possible to steer a boat having at least one drift (8) by using the handlebars (7) to rotate the rod (5) on itself in one direction or the other direction, because we go up to the wind (we blow it) when we put the center of thrust of the sail behind the center of reaction of the drift (sensi- the barycenter of the drift), and we go downwind (we shoot down) when we put the center of thrust of the sail in front of the center of reaction of the drift.

Selon une variante présentée aux figures 5 et 6, le mât (9) est mobile autour d'un axe parallèle à l'axe longitudinal de la coque; il est, par exemple, relié à la coque par 2 charnières (10 et 1 1) dont les axes sont selon l'axe longitudinal de la coque; ainsi, lorsque le mât tourne autour des charnières, son sommet décrit un cercle dans un plan transversal à la coque. Les 2 charnières peu¬ vent être remplacées par des articulations souples. Au repos, le mât est approximativement horizontal à la surface de l'eau et la voile repose sur l'eau du coté sous le vent (position B de la figure 6 et figure 7 qui montre une vue du haut).According to a variant presented in Figures 5 and 6, the mast (9) is movable about an axis parallel to the longitudinal axis of the hull; it is, for example, connected to the hull by 2 hinges (10 and 1 1) whose axes are along the longitudinal axis of the hull; thus, when the mast rotates around the hinges, its top describes a circle in a plane transverse to the hull. The 2 hinges can be replaced by flexible joints. At rest, the mast is approximately horizontal to the surface of the water and the sail rests on the water on the leeward side (position B in Figure 6 and Figure 7 which shows a view from above).

Pour son utilisation, on tire sur un bout (12), une corde ou équivalent fixé à l'avant de la voile au centre de son bord d'attaque; ainsi, on soulève le bord d'attaque de la voile, ce qui permet au vent de passer sous l'aile et d'aider à la relever. Puis on tire l'aile à soi jusqu'à saisir la tige de commande (5) ou le guidon (7). A l'aide de cette tige, on bascule la voile en position presque verti¬ cale (position D de la figure 6) puis on la borde.For its use, a end (12) is pulled, a cord or equivalent attached to the front of the sail at the center of its leading edge; this raises the leading edge of the sail, which allows the wind to pass under the wing and help to raise it. Then pull the wing towards you until you grab the control rod (5) or the handlebars (7). Using this rod, the sail is tilted into an almost vertical position (position D in FIG. 6) and then bordered.

Selon une variante présentée aux figures 8 et 9. la voilure peut équiper un bateau de taille moyenne ou grande; l'aile est manoeuvree d'une part à l'aide de 2 bouts (13), ou cordes ou filins de mise en place, reliant chaque extrémité de l'aile au bateau et d'autre part à l aide d'une écoute (14) reliant un point situé à l'arrière de l'aile, dans son plan de symétrie, au bateau.According to a variant presented in Figures 8 and 9. the wing can equip a medium or large boat; the wing is maneuvered on the one hand using 2 ends (13), or ropes or ropes for positioning, connecting each end of the wing to the boat and on the other hand using a sheet (14) connecting a point located at the rear of the wing, in its plane of symmetry, to the boat.

L'aile est mise en position proche de la verticale en tendant l'un des bouts (13) et la voile est bordée en tirant vers le vent l'écoute (14).The wing is brought into position close to the vertical by stretching one of the ends (13) and the sail is bordered by pulling the sheet towards the wind (14).

Pour une utilisation sur le sol, la voiture peut être adaptée à un véhicule à 2, 3 ou 4 roues; elle est montée au sommet d'un mât pouvant faire partie inté¬ grante du cadre du véhicule ou pouvant basculer sur la droite ou la gauche du véhicule comme dans son utilisation sur les petits bateaux de type planches à voile.For use on the ground, the car can be adapted to a vehicle with 2, 3 or 4 wheels; it is mounted on top of a mast which can form an integral part of the vehicle frame or which can tilt to the right or left of the vehicle as in its use on small boats of the windsurfing type.

Une version d'un véhicule à 2 roues et mât fixe est montrée figures 10 et 11.A version of a 2-wheeled vehicle with a fixed mast is shown in Figures 10 and 11.

L'aile est fixée au sommet du mât (15) par un élément souple; l'utilisateur a les pieds sur la barre inférieure (16) du cadre; il tient la voile par le guidon (7): il guide le véhicule à l'aide de son pied le plus en avant en agissant sur un guidon (17) relié à la roue avant.The wing is fixed to the top of the mast (15) by a flexible element; the user has his feet on the lower bar (16) of the frame; he holds the sail by the handlebars (7): he guides the vehicle using his foremost foot by acting on a handlebar (17) connected to the front wheel.

Selon une variante, la voilure est constituée d'une toile ou analogue (film. enveloppe...) tendue sur une armature articulée qui peut se plier ou se déplier à la manière d'un parasol de façon à amener toute la toile dans un petit volume rassemblé autour d'un manche ou au contraire à l'étendre proche d'un plan perpendiculaire à ce manche.According to a variant, the blade is made up of a canvas or the like (film, envelope, etc.) stretched over an articulated frame which can be folded or unfolded in the manner of a parasol so as to bring the entire canvas in a small volume collected around a sleeve or on the contrary to extend closer to a plane perpendicular to the handle.

L'armature de la voilure, montrée schématiquement aux figures 12. 13 et 14. est composée principalement d'une barre (5), ou manche, utilisée pour la manoeuvre de la voiture, et de au moins 3 barres (18. 19 et 20) qui s'articulent à une de leur extrémité reliée au sommet du manche (5) de façon à pouvoir être soit serrées contre ce manche, soit écartées jusqu'à en être sensiblement perpendiculaires.The frame of the blade, shown schematically in Figures 12. 13 and 14 is mainly composed of a bar (5), or sleeve, used for actuating the car, and at least 3 bars (18. 19 and 20) which are articulated at one of their ends connected to the top of the handle (5) so as to be either tightened against the handle, or spaced up to be substantially perpendicular.

La figure 15 montre l'armature repliée.Figure 15 shows the folded frame.

Une toile, ou analogue, est tendue entre les barres (18. 19 et 20). en consti¬ tuant ainsi les 2 plans principaux (21 et 22) de la voilure. Une corde (23). cable, ruban ou analogue ou une autre toile est placée entre les barres (18 et 20) de façon à être bien tendue lorsque l'armature est ouver¬ te, et constitue ainsi un lien souple pouvant faire bord d'attaque pour la voi¬ lure.A canvas, or the like, is stretched between the bars (18. 19 and 20). thus constituting the 2 main planes (21 and 22) of the airfoil. A rope (23). cable, tape or the like or another fabric is placed between the bars (18 and 20) so as to be well tensioned when the frame is open, and thus constitutes a flexible link which can form a leading edge for the car.

L'armature est maintenue ouverte par 3 petites barres (24, 25 et 26) dont cha- cune est reliée, à l'une de ses extrémités, à l'une des barres (18, 19 ou 20) par une articulation, et à l'autre extrémité à une pièce (27) commune aux 3 petites barres (24, 25 et 26), cette pièce (27) coulissant le long du manche (5) lorsque l'on plie ou déplie la voilure. C'est le blocage de cette pièce (27) à l'une de ses positions extrêmes au moyen d'un système approprié qui bloque l'armatu- re en position ouverte, position d'utilisation.The frame is kept open by 3 small bars (24, 25 and 26) each of which is connected, at one of its ends, to one of the bars (18, 19 or 20) by a joint, and at the other end to a part (27) common to the 3 small bars (24, 25 and 26), this part (27) sliding along the handle (5) when the wing is folded or unfolded. It is the blocking of this part (27) at one of its extreme positions by means of an appropriate system which blocks the armature in the open position, position of use.

Selon une variante, pour améliorer l'efficacité, l'espace situé entre les 2 bar¬ res (18 et 20), proche du bord d'attaque de la voilure, comporte une toile (28) ou analogue reliant ces 2 barres (18 et 20), cette toile pouvant être équipée d'une ou plusieurs lattes (29) souples assez longues pour se courber dés que la voilure est ouverte en position d'utilisation, car ces lattes (29) se trouvent coincées entre le point fixe sommet de l 'armature et le lien souple (23), corde ou autre, tendu qui constitue le bord d'attaque de la voilure.According to a variant, to improve efficiency, the space located between the 2 bars (18 and 20), close to the leading edge of the airfoil, comprises a canvas (28) or the like connecting these 2 bars (18 and 20), this fabric being able to be fitted with one or more flexible slats (29) long enough to bend as soon as the airfoil is open in the use position, because these slats (29) are wedged between the fixed top point of the frame and the flexible link (23), rope or the like, which is stretched the leading edge of the wing.

Selon une variante améliorée, la voilure comporte un autre morceau (30) triangulaire de tissu, toile ou analogue, tendu (voilure ouverte) entre, d'une part, le lien souple (23) qui constitue le bord d'attaque de la voilure et, d'autre part, les 2 parties de toiles (21 et 22) qui constituent les 2 plans principaux de la voilure, ce morceau de toile (30) pouvant recouvrir les 3 petites barres (24, 25 et 26).According to an improved variant, the blade comprises another triangular piece (30) of fabric, canvas or the like, stretched (open blade) between, on the one hand, the flexible link (23) which constitutes the leading edge of the blade and, on the other hand, the 2 parts of fabrics (21 and 22) which constitute the 2 main planes of the wing, this piece of fabric (30) being able to cover the 3 small bars (24, 25 and 26).

Selon une variante, la base du mât (31 ) n'est pas fixée à une coque de bateau mais comporte, comme le montre la figure 16, un petit siège (32) sur lequel on s'assoit pour utiliser cette voilure en delta-plane. L'engin est alors guidé par l'orientation que l'on donne à la barre (5) par rapport au mât (31).According to a variant, the base of the mast (31) is not fixed to a boat hull but comprises, as shown in FIG. 16, a small seat (32) on which one sits to use this wing in delta- plane. The machine is then guided by the orientation that is given to the bar (5) relative to the mast (31).

APPLICATIONS: Engin de plage, bateaux de sport et de loisir, bicyclette à voi¬ le, delta-plane. APPLICATIONS: Beach machine, sport and leisure boats, bicycle, hang-glider.
