Abstract

Nouvelle voile pour planche a voile, skis de neige, patins a glace et a roulettes et plus generalement tous sports de glisse. La voile (1) a profil convexe stable en forme d'ailes de goeland est constituee d'un tissu en secteur de cercle muni de deux fenetres transparentes (2) et tendu sur une armature en alliage leger comprenant deux tubes de bordure (3) emboites dans un tube frontal courbe (4), un tube central legerement cintre (7) servant a former un 'V' par l'action des deux tubes d'etarquage (5) sur la liaison (12) et, un tube de soutien courbe (6). La voile est tendue a l'aide de 'Velco' en bouts d'aile (9) et par des lattes pre-cambrees (8) maintenues elles aussi par du 'Velcro' (10). La voile ne presentant qu'un seul cote au vent peut etre construite en materiaux rigides afin d'en augmenter encore le rendement aerodynamique.New sail for windsurfing, snow skis, ice and roller skates and more generally all board sports. The sail (1) with a stable convex profile in the form of gull's wings consists of a fabric in a sector of a circle provided with two transparent windows (2) and stretched over a light alloy frame comprising two border tubes (3) nested in a curved front tube (4), a slightly arched central tube (7) used to form a 'V' by the action of the two stretching tubes (5) on the link (12) and, a support tube curve (6). The sail is stretched using 'Velco' at the wing tips (9) and by pre-arched slats (8) also held by 'Velcro' (10). The sail having only one side to the wind can be built in rigid materials in order to further increase its aerodynamic efficiency.

Description

Voile à effets propulseur et de sustentation variables. Sail with variable propellant and lift effects.
La présente invention concerne un nouveau type de voile pour des engins tels que la planche à voile, le char à voile, le bateau à voile et plus généralement pour tous les sports de glisse tels que par exemple le ski et le patin à glace et à roulettes.The present invention relates to a new type of sail for gear such as windsurfing, sand yachting, sailing boat and more generally for all board sports such as for example skiing and ice skating and casters.
Les voiles actuellement utilisées ont pour carac¬ téristique, quelque soit leur forme, de se servir de la force du vent en pivotant autour d'un axe vertical ; la composante propulsive étant alors perpendiculaire à cet axe.The sails currently used have the characteristic, whatever their shape, of using the force of the wind by pivoting about a vertical axis; the propellant component then being perpendicular to this axis.
Un certain nombre de brevets qui décrivent de nou velles voiles capables de se régler suivant les trois dime sions ont cependant été déposés. Le plus ancien brevet et sans aucun doute celui qui décrit le mieux les caractéris¬ tiques' de ces nouvelles voiles est celui déposé par Rudow Rummler le 14 janvier 1935 aux Etats-Unis dont le numéro est 2.170.914 ; les figures 1 à 10 sont en particulier très explicites. Deux autres brevets américains, celui de Hugh Perrin, déposé le 15 mai 1968 dont le numéro est 3.455.261 décrit une voile cerf-volant à l'aide des figures de 1 à 5, et celui de Spivack déposé le 9 décembre 1975 propose une voile pour patins à glace. Un brevet français déposé par Jean-Paul Lenoble en février 1972 dont ie numéro est 2.173.3 reprend avec force détails et quelques montages particu¬ liers essentiellement les mêmes principes de voilure déjà bien décrits par le brevet américain de Rudow Ru mler. Un autre brevet américain déposé par Grey M. Gurley en Mars 5 1978 dont le numéro est 4.077.345 particularise le type de voile précédent en l'orientant autour d'un axe oblique fixé à l'avant d'un bateau. Enfin, un dernier brevet allemand déposé par Gunter M. Voss en février 1980 et dont le numéro est 2.833.616 concerne une voile spécialisée aux ° planches à voile.A certain number of patents which describe new sails capable of adjusting according to the three dimensions have however been filed. The oldest patent and certainly the one that best describes the caractéris¬ ticks' of these new sails is one filed by Rudow Rummler January 14, 1935 in the United States whose number is 2170914; Figures 1 to 10 are in particular very explicit. Two other American patents, that of Hugh Perrin, deposited on May 15, 1968, the number of which is 3,455,261 describes a kite sail using figures from 1 to 5, and that of Spivack deposited on December 9, 1975 proposes a sail for ice skates. A French patent filed by Jean-Paul Lenoble in February 1972, the number of which is 2,173.3 takes up with great detail and some particular assemblies essentially the same wing principles already well described by the American patent of Rudow Ru mler. Another American patent deposited by Gray M. Gurley in March 5 1978 whose number is 4.077.345 particularizes the previous type of sail by orienting it around an oblique axis fixed to the front of a boat. Finally, a last German patent filed by Gunter M. Voss in February 1980 and whose number is 2,833,616 relates to a specialized sail with ° sailboards.
La présente voile appartient à ce nouveau type de voile capable de s'orienter suivant les trois axes afin d'obtenir à volonté des effets propulseurs et de sustenta¬ tion. Cependant, à la différence de tous les brevets pré- 5 cédemment cités, qui décrivent tous des voiles à forme transversale concave, la voile proposée par le présent brevet est caractérisée par une forme transversale convexe stable du type aile de goéland. En effet, un profil concave a toujours tendance à se retourner par fort vent puisque 0 si on l'écarté de sa position d'équilibre où les deux moitiés de la voile offrent la même surface, perpendiculai¬ rement au vent, une des moitiés reçoit de plus en plus de vent tandis que l'autre en reçoit de moins en inoins à l'in¬ verse d'un profil convexe en "V" qui tend toujours à ramener 5 la voile* à sa position d'équilibre. En outre, un profil convexe en "V facilite l'écoulement de l'air, et lors de rafales* il a tendance à se refermer en amortissant de ce fait les sautes de vent.The present sail belongs to this new type of sail capable of being oriented along the three axes in order to obtain propellant and lift effects at will. However, unlike all the previously cited patents, which all describe sails of concave transverse shape, the sail proposed by this patent is characterized by a stable convex transverse shape of the gull wing type. Indeed, a concave profile always tends to turn around in strong wind since 0 if it is removed from its equilibrium position where the two halves of the sail offer the same surface, perpendicular to the wind, one of the halves receives more and more wind while the other receives less and lefs to in¬ pays a convex profile "V" which always tends to return the sail 5 * to its equilibrium position. In addition, a convex "V" profile facilitates the flow of air, and during gusts * it tends to close, thereby dampening wind swings.
De façon avantageuse, la voile présente un bord d'attaque divergeant vers l'arrière, une section centrale fortement courbée de façon concave au vent au voisinage du sommet du bord d'attaque et se poursuivant de façon progres¬ sivement plus rectiligne vers l'extrémité arrière, et un bord de fuite joignant les deux extrémités du bord d'at- 5 taqueà ladite extrémité arrière pour former deux pansAdvantageously, the sail has a leading edge diverging towards the rear, a central section strongly curved concave to the wind in the vicinity of the top of the leading edge and continuing progressively more rectilinearly towards the rear end, and a trailing edge joining the two ends of the leading edge to said rear end to form two sides
OMFI v,τ?o divergeant en "V" de façon convexe au vent de part et d'autre de ladite section centrale. Le sommet du bord d'attaque est de préférence arrondi et son ouverture est de préférence de l'ordre de 110 à 130°. La section centrale peut être légèrement convexe et son extrémité arrière pour présenter une forme de S dissymétrique.OMFI v, τ? O diverging in "V" convex to the wind on either side of said central section. The top of the leading edge is preferably rounded and its opening is preferably of the order of 110 to 130 °. The central section can be slightly convex and its rear end to present an asymmetrical S shape.
La voile peut présenter un élément de soutien élo gné de la voilure sous celle-ci et deux barres de rappel divergeant en avant à partir de ladite extrémité arrière, formant par exemple un système triangulaire avec la barre de soutien.The sail may have a support element away from the wing under the latter and two return bars diverging forward from said rear end, for example forming a triangular system with the support bar.
De préférence, la voile comporte une ossature en éléments allongés sensiblement rigides, notamment tubulaire et une voilure tendue sur l'ossature avec, de préférence, un ensemble de lattes précambrées concaves au vent près du bord d'attaque. Les liaisons entre les éléments d'ossature peuvent être avantageusement souples pour faciliter une certaine défor abilité de la voile dont la forme est maintenue par sa propre tension.Preferably, the sail comprises a framework of substantially rigid elongated elements, in particular tubular and a wing stretched over the framework with, preferably, a set of pre-cambered slats concave in the wind near the leading edge. The connections between the framing elements can advantageously be flexible to facilitate a certain deformability of the sail, the shape of which is maintained by its own tension.
Afin de bien décrire un montage possible de la voile, elle est représentée sous trois angles : la figure 1 est une vue de côté et par dessous, la figure 2 est une vue de dessous, la figure 3 est une vue de face avec une petite rotation et les figures 4 et 5 sont des vues de détails.In order to properly describe a possible assembly of the sail, it is represented from three angles: Figure 1 is a side view and from below, Figure 2 is a view from below, Figure 3 is a front view with a small rotation and Figures 4 and 5 are detail views.
La voile 1 à profil convexe stable en forma d'aile de goéland est constituée d'un ensemble de portions trapé¬ zoïdales de tissu consues entre elles lui donnant l'aspect général d'un secteur de cercle et munie de deux fenêtres transparentes 2 pour la bonne vision de l'opérateur. La voile 1 est tendue sur une armature en alliage léger com¬ posée de : deux tubes de bordure 3 emboîtés dans un tube frontal courbé 4, un tube central 7 légèrement, cintré sui- vant un profil en "S" servant à former le profil traπversal convexe en "V" par l'action des deux tubes d'étarquage 5 sur la liaison 12 et enfin un tube de soutien coubé 6. Le raidissement de la toile et le maintien de l'emboîtage des tubes de bordure 3 dans le tube frontal courbé 4 se 5 fait en tirant sur les manches contenant ces tubes de bor¬ dure et en refermant les "Velcro" 9 des bouts d'aile. "Velcro" est une marque déposée désignant des bandes tex¬ tiles auto-adhérentes permettant des ouvertures et ferme¬ tures rapides répétées. La voile 1 est en outre tendue dans ° le sens longitudinal par les lattes 8 pré-cambrées, main¬ tenues par des "Velcro" 10, qui avec les manches contenant . les tubes 3 et 4 donnent à l'ensemble une bonne pénétration dans l'air. La figure 4 montre le détail 13 : les tubes de bordure 3 passent à l'intérieur de bandes de cuir respecti- ^ ve ent solidaires grâce aux vis 15 des tubes d'étarquage 5 et du tube de soutien 6 avant de s'emboîter à l'intérieur du tube frontal courbé 4 en prenant appui sur les butées 17 les baques 16 maintiennent en position les tubes 5 et le tube 6. Le détail 12 sur la figure 5 montre l'étarquage de l 0 voile à l'aide de la cordelettes 19 passant dans l'oeillet 18 La voile peut être utilisée seule ou acultativemen reliée à un mat 20 de l'engin à propulser. Le πat 20 peut par exemple être relié à l'engin par une première rotule 21 tandis qur l'autre extrémité est reliée à la voile par 5 un manchon 22 coulissant sur la barre de soutien 6 avec une seconde rotule 23.The sail 1 with a stable convex profile in the form of a gull's wing consists of a set of trapezoidal zoidal portions of fabric made up together giving it the general appearance of a sector of a circle and provided with two transparent windows 2 for the operator's good vision. The sail 1 is stretched over a light alloy frame composed of: two border tubes 3 fitted into a curved front tube 4, a slightly curved central tube 7 following an "S" profile used to form the profile transverse convex in "V" shape by the action of the two stretching tubes 5 on the link 12 and finally a curved support tube 6. The stiffening of the fabric and the maintenance of the fitting of the border tubes 3 in the front tube 4 is bent 5 by pulling on the sleeves containing these hard bor¬ tubes and closing the "Velcro" 9 of the wing tips. "Velcro" is a registered trademark designating self-adhesive textile tapes allowing repeated rapid openings and closings. The sail 1 is further stretched in ° the longitudinal direction by the pre-arched slats 8, main¬ held by "Velcro" 10, which with the sleeves containing. tubes 3 and 4 give the assembly good penetration into the air. FIG. 4 shows the detail 13: the border tubes 3 pass inside strips of leather respectively secured by means of the screws 15 of the stretching tubes 5 and of the support tube 6 before fitting into within the curved head pipe 4 by bearing on the stops 17 hold the Baques 16 in position 5 and the tube 6. the tubes 12 detail in Figure 5 shows the tensioning of 0 sail using the cords 19 passing through the eyelet 18 The sail can be used alone or acultativemen connected to a mast 20 of the vehicle to be propelled. The πat 20 can for example be connected to the machine by a first ball joint 21 while the other end is connected to the sail by 5 a sleeve 22 sliding on the support bar 6 with a second ball joint 23.
Dans le cas de l'utilisation de la voile pour la planche de saut où les pieds sont rendus solidaires de la planche à l'aide de petites bandes de tissu synthétique fixées à celle-ci, le saut s'effectue simplement par rétrac¬ tion des jambes et contrairement aux voiles classiques, la course de l'engin peut continuer sans à coup puisque la voile reste constamment en position propulsive.In the case of the use of the sail for the jump board where the feet are made integral with the board using small strips of synthetic fabric attached thereto, the jump is made simply by retraction legs and unlike conventional sails, the race of the machine can continue smoothly since the sail remains constantly in the propelling position.
La nouvelle voile a pour caractéristique de ne re- cevoir le vent que d'un seul côté, l'autre côté étant toujour sous le vent. Cette particularité est très importante puisqu'elle permet l'utilisation de voiles préformées en matériaux rigides avec des profils aérodynamiques du type aile d'avion. Les changements de bord se font par bordage de la voile suivi du passage de celle-ci par dessus la tête de l'opérateur avec reprise immédiate du vent sur l'autre bord ; cette technique est bien plus facile et rapide que la manière classique de changer de bord par basculement du mât vers l'arrière et passage de l'opérateur devant celui-ci, tel que cela se pratique avec les voiles ac¬ tuelles de planches à voile.The characteristic of the new sail is that it only receives the wind on one side, the other side being always downwind. This feature is very important since it allows the use of preformed sails made of rigid materials with aerodynamic profiles of the airplane wing type. The edge changes are made by planking the sail followed by the passage of the sail over the head of the operator with immediate recovery of the wind on the other edge; this technique is much easier and faster than the conventional way of changing edges by tilting the mast backwards and passing the operator in front of it, as is done with the current sails of windsurfers .
Les multiples orientations possibles de la voile permettent de créer une force propulsive ayant pour effet de tirer 1'engin en avant et vers le haut et cette susten¬ tation plus ou moins grande suivant la taille voulue de la voile doit en outre permettre de grandes vitesses dû à l'effet d'aquaplanning qui en résulte pour des engins léger The multiple possible orientations of the sail make it possible to create a propulsive force having the effect of pulling the machine forward and upwards and this more or less large susten¬ tion depending on the desired size of the sail must also allow high speeds due to the resulting aquaplanning effect for light equipment
