Description

La présente invention concerne un dispositif de commande et de contrôle amélioré pour une aile de traction du type « cerf volant », ou pour un gréement de voilier (intégré à la bôme).The present invention relates to an improved control and control device for a "kite" type kite, or for a sailboat rig (built into the boom).

L'invention concerne en outre une aile de cerf volant ou une bôme de voilier, munie d'un tel dispositif.The invention further relates to a kite wing or a sailboat boom, provided with such a device.

L'invention sera décrite en regard de son application à une aile de cerf volant, intégré à la barre de ladite aile, sans être limitée à cette seule application.The invention will be described with regard to its application to a kite wing, integrated in the bar of said wing, without being limited to this single application.

On sait que les ailes cerf volant comportent une ou plusieurs voilures souples, de forme généralement elliptique ou semi elliptique, plate ou semi plate et dont la concavité est destinée à être placée dans le vent pour constituer un moyen de traction, et éventuellement de déplacement d'un utilisateur (ou utilisatrice) ou autre qui est relié(e) à l'aile par des câbles appelés lignes.It is known that the kite wings have one or more flexible wings, of generally elliptical or semi-elliptical shape, flat or semi-flat and whose concavity is intended to be placed in the wind to constitute a means of traction, and possibly displacement of a user (or user) or other who is connected to the wing by cables called lines.

De telles ailes ont de nombreuses applications possibles, notamment les sports de glisse, terrestre, eau, neige, et utilisées par exemple pour la planche nautique (telle que le « kitesurf » en anglais), la planche à roulette (« mountain board » en anglais), la planche de ski (« kitesnow » en anglais), le char (« buggy » en anglais), engins qui sont tractés à l'aide d'un cerf volant de traction. Ces ailes servent à la traction de tous types d'engin nautique ou terrestre, glissant ou roulant, mais aussi sont utilisés pour des systèmes de production d'électricité utilisant la force générée par de telles ailes.Such wings have many possible applications, including sliding sports, land, water, snow, and used for example for wakeboarding (such as "kitesurfing" in English), skateboarding ("mountain board" in English), the snowboard ("kitesnow" in English), the chariot ("buggy" in English), machines that are towed using a kite traction. These wings are used to pull all types of nautical or terrestrial equipment, slipping or rolling, but also are used for power generation systems using the force generated by such wings.

Une aile de ce type comporte généralement un bord d'attaque (partie avant) et un bord de fuite (partie arrière).A wing of this type generally comprises a leading edge (front portion) and a trailing edge (rear portion).

L'aile comporte en outre :

  • deux lignes qui gèrent la direction et la puissance, dites arrières, reliées aux extrémités arrière latérales gauche et droite de l'aile ;
  • deux lignes dites avant, liées au bord d'attaque de l'aile ;
  • une cinquième ligne dite ligne de sécurité, reliée à l'utilisateur par un système de largage et fixée directement ou indirectement, via un bridage optionnel, sur le bord d'attaque de l'aile, ou sur une des quatre lignes avant et arrière.
The wing further comprises:
  • two lines that manage the direction and the power, called rear, connected to the rear left and right ends of the wing;
  • two lines said before, related to the leading edge of the wing;
  • a fifth line called safety line, connected to the user by a delivery system and fixed directly or indirectly, via an optional clamping, on the leading edge of the wing, or on one of the four front and rear lines.

Les extrémités des quatre lignes arrière et avant, opposées à l'aile, sont reliées à l'utilisateur par l'intermédiaire d'une barre de contrôle et plus précisément, les extrémités des deux lignes avant sont reliées à un bout central traversant la barre, tandis que les extrémités des lignes arrière sont fixées aux extrémités gauche et droite de la barre.The ends of the four rear and front lines, opposed to the wing, are connected to the user via a control bar and more precisely, the ends of the two front lines are connected to a central end crossing the bar. , while the ends of the back lines are attached to the left and right ends of the bar.

La partie centrale de la barre est reliée à l'utilisateur/trice par un système de largage connecté à un harnais porté par l'utilisateur ou équivalent. La barre est tenue par l'utilisateur/trice avec ses deux mains.The central portion of the bar is connected to the user by a delivery system connected to a user-worn harness or equivalent. The bar is held by the user with both hands.

Selon la force du vent, l'utilisateur règle la puissance de traction de l'aile en l'inclinant plus ou moins, selon un plan variable délimité par les points d'accroche des lignes avant et arrière, et ce en raccourcissant ou en allongeant la distance entre le point d'accroche au harnais.Depending on the force of the wind, the user adjusts the traction power of the wing by tilting more or less, according to a variable plan defined by the points of attachment of the front and rear lines, and this by shortening or lengthening the distance from the point of attachment to the harness.

Selon la force du vent, l'utilisateur peut varier la puissance de traction de l'aile en l'inclinant plus ou moins à l'aide de la barre coulissante reliée aux lignes « arrière » (pilotage et puissance) par rapport aux lignes « avant » (traction).Depending on the wind force, the user can vary the traction power of the wing by tilting more or less using the sliding bar connected to the lines "rear" (control and power) compared to the lines " before "(traction).

Si la force du vent est trop ou pas assez importante pour l'utilisateur, ce dernier peut également grâce un système de réglage et de renvoi central qui relie, le plus généralement les deux lignes avant, régler la puissance de son aile et ainsi étendre sa plage d'utilisation. Cette opération modifie le calage de l'incidence de l'aile.If the wind force is too important or not important enough for the user, the latter can also thanks to a system of adjustment and central referral which connects, most generally the two front lines, adjust the power of his wing and thus extend his range of use. This operation modifies the wedging of the incidence of the wing.

De manière connue, cette manoeuvre est effectuée via un système de réglage et de renvoi central qui relie, le plus généralement les deux lignes avant de manière centrale et qui coulisse perpendiculairement à travers ou à proximité de la barre. Ledit système permet d'ajuster l'inclinaison incidente de l'aile, en diminuant ou en allongeant la distance entre le bord de fuite arrière et le point d'accroche au harnais avant. Le même système ou son équivalent peut être réalisé aussi à partir des lignes arrière.In known manner, this maneuver is performed via a central adjustment and return system which connects, most generally the two front lines so central and slides perpendicularly across or near the bar. Said system makes it possible to adjust the incident inclination of the wing, decreasing or lengthening the distance between the rear trailing edge and the point of attachment to the front harness. The same system or its equivalent can be realized also from the back lines.

Ainsi, par poussée ou traction sur la barre, on diminue ou augmente l'incidence de l'aile ce qui par effet aérodynamique diminue ou augmente la tension dans les lignes (avant et arrière).Thus, by pushing or pulling on the bar, it decreases or increases the incidence of the wing which by aerodynamic effect decreases or increases the tension in the lines (front and rear).

L'utilisateur/trice, pour actionner le système de réglage de renvoi central, doit donc libérer une main, et il/elle ne tient alors la barre que d'une seule main.The user, to operate the central return adjustment system, must release a hand, and he / she then holds the bar with one hand.

Ceci constitue un inconvénient majeur en termes de contrôle de l'aile, d'autant plus gênant que l'utilisateur/trice a justement besoin de mieux contrôler la barre au moment où la force et/ou la direction du vent change.This is a major drawback in terms of control of the wing, all the more annoying that the user needs to better control the bar when the force and / or wind direction changes.

Des barres de kite comprenant des mécanismes de réglage la longueur des brins arrières sont connues des documents DE20315464U et WO2011014904 .Kite bars comprising mechanisms for adjusting the length of the rear strands are known from the documents DE20315464U and WO2011014904 .

On a proposé selon la demande de brevet français n° 1361291 déposée par le demandeur, et publié sous le numéro FR3013227 , une barre comportant un enrouleur central sur la barre, actionnable d'une seule main, et associé à un mécanisme de renvoi (interne à la barre) lié aux deux extrémités des câbles arrière.It has been proposed according to the French patent application no. 1361291 filed by the applicant, and published under number FR3013227 , a bar having a central reel on the bar, operable with one hand, and associated with a return mechanism (internal to the bar) connected to both ends of the rear cables.

Ce système, bien qu'apportant une amélioration avantageuse aux barres antérieures, est susceptible d'amélioration, au regard de la rapidité et la réactivité, des efforts que doit fournir l'utilisateur/trice, et de la puissance de traction sur les câbles.This system, while providing an advantageous improvement to the previous bars, is likely to improve, in terms of speed and responsiveness, the efforts that must provide the user, and the traction power on the cables.

De plus, les mécanismes connus ne sont pas totalement étanches et la présence de sable affecte leur fonctionnement et leur fiabilité.In addition, the known mechanisms are not completely sealed and the presence of sand affects their operation and reliability.

La présente invention a pour objet une barre de commande et de contrôle, pour aile de traction, qui permette à l'utilisateur/trice d'ajuster ou de régler la puissance de l'aile, c'est-à-dire l'inclinaison (appelée l'incidence) de l'aile tout en maintenant la barre avec ses deux mains, et ce à moindre effort, de manière rapide et réactive, et offrant une précision inégalée, et enfin qui soit quasiment étanche au sable.The present invention relates to a control and control bar, for traction wing, which allows the user to adjust or adjust the power of the wing, that is to say the inclination (called the incidence) of the wing while maintaining the bar with both hands, and this with less effort, quickly and reactively, and offering unparalleled accuracy, and finally that is almost sealed to sand.

A cette fin, selon l'invention, la barre de commande et de contrôle pour aile du type cerf volant dite de traction, susceptible d'être associée à deux câbles avant et deux câbles arrière, les câbles étant destinés à être reliés par une extrémité à ladite aile, la barre étant de forme allongée sensiblement cylindrique, les câbles arrière étant reliés à la barre, et les câbles avant étant destinés à être reliés à l'utilisateur, des moyens étant prévus pour raccourcir ou allonger les câbles avant ou arrière, afin de faire varier l'inclinaison / l'incidence de l'aile, les moyens de raccourcissement / allongement des câbles arrière étant intégrés à la barre de manière à être actionnables par l'une des mains de l'utilisateur/trice sans lâcher la barre, chaque câble arrière étant associé à un système de renvoi créant, pour chaque câble arrière, un brin de câble de longueur variable, caractérisée en ce que ledit système de renvoi est mobile en translation parallèlement à l'axe de la barre, et est relié à des moyens de rappel, et en ce que la barre comporte des moyens aptes à bloquer/débloquer la position du système de renvoi le long de la barre, en fonction des forces de traction exercées sur les câbles, lesdits moyens de blocage/déblocage étant accessibles à au moins un doigt de l'utilisateur/trice depuis l'extérieur de la barre.To this end, according to the invention, the control and control bar for wing kite type said traction, may be associated with two front cables and two rear cables, the cables being intended to be connected by one end at said wing, the bar being of substantially cylindrical elongate shape, the rear cables being connected to the bar, and the front cables being intended to be connected to the user, means being provided for shortening or lengthening the front or rear cables, in order to vary the inclination / the incidence of the wing, the means of shortening / elongation of the rear cables being integrated in the bar so as to be operable by one of the hands of the user without letting go of the bar, each rear cable being associated with a return system creating, for each rear cable, a cable strand of variable length, characterized in that said return system is mob it is in translation parallel to the axis of the bar, and is connected to return means, and in that the bar comprises means able to lock / unlock the position of the return system along the bar, depending on tensile forces exerted on the cables, said locking / unlocking means being accessible to at least one finger of the user from the outside of the bar.

Ainsi, l'utilisateur/trice raccourcit / allonge les câbles d'une part sans lâcher la barre, et d'autre part avec un effort réduit, grâce aux moyens de rappel.Thus, the user shortens / lengthens the cables on the one hand without releasing the bar, and on the other hand with reduced effort, thanks to the return means.

Avantageusement, la barre comporte un élément longiligne, telle qu'une réglette, dont une extrémité est solidaire du système de renvoi mobile et dont l'autre extrémité est reliée aux moyens de rappel.Advantageously, the bar comprises an elongate member, such as a strip, one end of which is secured to the mobile return system and the other end of which is connected to the return means.

De préférence, ledit élément longiligne, les moyens de renvoi, les brins de câble de longueur variable et les moyens de rappel sont disposés à l'intérieur de la barre.Preferably, said elongate member, the return means, the cable strands of variable length and the return means are disposed within the bar.

Le système de renvoi comporte un coulisseau mobile.The return system comprises a movable slide.

Particulièrement, l'élément longiligne est une barrette ou une tige rigide.In particular, the elongated element is a bar or a rigid rod.

La barre comporte des moyens aptes à bloquer et débloquer la translation de l'élément longiligne, et ces derniers comportent un tenon mâle mobile, apte à prendre deux positions stables, à savoir une position de blocage, où il coopère avec des lumières ou encoches prévues sur l'élément longiligne, et une position de déblocage escamotée, libérant la translation de l'élément longiligne et donc du système de renvoi.The bar comprises means capable of blocking and unblocking the translation of the elongate member, and these comprise a movable male stud, able to take two stable positions, namely a locking position, where it cooperates with the slots or notches provided on the elongate element, and a retracted unlocking position, releasing the translation of the elongate element and therefore the return system.

Plus spécifiquement, le tenon est relié par un mécanisme de transmission à un bouton poussoir actionnable par un doigt de l'utilisateur/trice depuis l'extérieur de la barre. Ainsi, la barre comporte un mécanisme d'actionnement, en particulier comprenant un bouton poussoir accessible de l'extérieur de la barre, et un mécanisme de transmission reliant à l'intérieur de la barre ledit bouton poussoir au tenon.More specifically, the post is connected by a transmission mechanism to a push button actuated by a user's finger from outside the bar. Thus, the bar comprises an actuating mechanism, in particular comprising a push button accessible from outside the bar, and a transmission mechanism connecting inside the bar said push button to the post.

Lesdits moyens de rappel comportent un vérin à gaz ou un ressort de rappel.Said return means comprise a gas cylinder or a return spring.

Ledit élément longiligne est relié d'une part aux moyens de rappel et d'autre part au système de renvoi par une poulie additionnelle respective.Said elongate element is connected on the one hand to the return means and on the other hand to the return system by a respective additional pulley.

L'invention vise de plus un ensemble pour aile de traction de type cerf volant, ou une voile de voilier, de parapente ou de planche à voile, comprenant une voile ou une aile et au moins un câble ou ligne reliant l'aile à ladite barre de commande telle que décrite et revendiquée, ou reliant la voile audit dispositif tel que décrit et revendiqué.The invention furthermore relates to a kite-type traction wing assembly, or a sailboat, paraglider or windsurf sail, comprising a sail or wing and at least one cable or line connecting the wing to said control bar as described and claimed, or connecting the sail to said device as described and claimed.

L'invention est susceptible d'être associée à des ailes dans de nombreuses applications, notamment les sports de glisse, terrestre, eau, neige, et utilisées par exemple pour la planche nautique, la planche à roulette, la planche de ski, le char à voile. Ces ailes servent à la traction de tous types d'engin nautique ou terrestre, glissant ou roulant, mais aussi sont utilisés pour des systèmes de production d'électricité utilisant la force générée par de telles ailes.The invention is likely to be associated with wings in many applications, including sliding sports, land, water, snow, and used for example for wakeboarding, skateboarding, ski board, tank sailing. These wings are used to pull all types of nautical or terrestrial equipment, slipping or rolling, but also are used for power generation systems using the force generated by such wings.

On a représenté sur la figure 1 une vue schématique de principe d'une voile 1 de forme parallélépipédique ou carrée, bombée, et reliée à une barre de commande 2, tenue par un utilisateur/trice, qui n'est pas représenté(e), par l'intermédiaire de deux câbles ou lignes avant 3 et 4, et de deux lignes ou câbles arrière 5 et 6.We have shown on the figure 1 a schematic view of the principle of a sail 1 of parallelepipedal or square shape, convex, and connected to a control bar 2, held by a user / trice, which is not shown, via two cables or front lines 3 and 4, and two lines or rear cables 5 and 6.

Les lignes ou câbles 3, 4, 5, et 6 ont une extrémité liée chacune à un coin respectif de la voile 1. Les extrémités 6A et 5A, opposées à la voile 1, des câbles arrière 5 et 6, sont reliées aux extrémités 2A, 2B de la barre 2. Les extrémités 3A et 4A (opposées à la voile 1) des câbles avant 3 et 4 sont reliées à un bout central commun 10 qui passe à proximité ou au centre de la barre de commande 2. Au-delà de la barre 2, opposée à la voile, le bout 10 dépassant de la barre est relié à une poignée ou anneau dit « de largage » 10A.The lines or cables 3, 4, 5, and 6 have one end each connected to a respective corner of the sail 1. The ends 6A and 5A, opposite the sail 1, the rear cables 5 and 6, are connected to the ends 2A 2A of the bar 2. The ends 3A and 4A (opposite the sail 1) of the front cables 3 and 4 are connected to a common central end 10 which passes near or in the center of the control bar 2. Beyond of the bar 2, opposite the sail, the tip 10 protruding from the bar is connected to a handle or ring called "drop" 10A.

De manière connue, en fonction de la vitesse et/ou de la direction du vent, symbolisée par la flèche V, l'utilisateur/trice tenant la barre 2 modifie la longueur des câbles avant 3 et 4, par exemple de la manière montrée sur la figure 1 où la voile prend alors une position représentée en pointillés et référencée 1A.In known manner, as a function of the speed and / or direction of the wind, symbolized by the arrow V, the user holding the bar 2 modifies the length of the front cables 3 and 4, for example in the manner shown on FIG. the figure 1 where the sail then takes a position shown in dotted lines and referenced 1A.

Ainsi, l'utilisateur peut modifier l'angle d'attaque de la voile par rapport à la force du vent, et donc régler et gérer la puissance de traction de l'aile.Thus, the user can change the angle of attack of the sail relative to the wind force, and thus adjust and manage the traction power of the wing.

L'utilisateur/trice peut ainsi se déplacer, sur l'eau en étant associé à une planche à voile ou équivalent, ou encore sur terre sur un char à voile ou équivalent.The user can move on the water being associated with a windsurf board or equivalent, or on land on a sand yacht or equivalent.

La figure 2 montre une vue schématique de la barre 2 de la figure 1. La barre est reliée à la voile 1 par l'intermédiaire des câbles avant 3 et 4 dont les extrémités 3A et 4A sont reliées au bout commun L qui traverse la barre de commande, et les câbles arrière 5 et 6 dont les extrémités distales respectives 5A et 6A sont fixées aux extrémités 2A et 2B de la barre de commande 2.The figure 2 shows a schematic view of the bar 2 of the figure 1 . The bar is connected to the sail 1 via the front cables 3 and 4 whose ends 3A and 4A are connected to the common end L which passes through the control bar, and the cables rear 5 and 6, the respective distal ends 5A and 6A are fixed to the ends 2A and 2B of the control bar 2.

En régime « de croisière » d'utilisation, l'utilisateur/trice tient la barre 2 par ses mains gauche 7 et droite 8 tandis qu'un harnais (connu en lui-même et non représenté) relie la barre 2 à l'utilisateur/trice qui n'est pas représenté(e).In use "cruise" mode, the user holds the bar 2 by his left 7 and right 8 hands while a harness (known in itself and not shown) connects the bar 2 to the user who is not represented.

La barre de l'invention comporte un système de réglage de la longueur des câbles arrière 5 et 6, permettant de régler la puissance de l'aile, en raccourcissant / allongeant lesdits câbles, ledit système étant actionnable par l'une des mains de l'utilisateur/trice sans lâcher la barre. Les câbles ou lignes avant sont donc, dans l'exemple de réalisation décrit, de longueur fixe.The bar of the invention comprises a system for adjusting the length of the rear cables 5 and 6, for adjusting the power of the wing, by shortening / lengthening said cables, said system being actuatable by one of the hands of the user without letting go of the bar. The cables or front lines are, in the embodiment described, fixed length.

La figure 3 montre en perspective la barre de l'invention où l'on retrouve les éléments décrits ci-dessus, et en outre les éléments suivants :

  • deux manchons coudés d'extrémités 2C et 2 D pour le passage des câbles 5 et 6, respectivement ;
  • deux tiges filetées longitudinales 2E et 2F, pénétrant dans la barre 2 aux extrémités respectives de cette dernière et destinées au serrage / blocage des extrémités de la barre ;
  • un manchon 10 radial, réalisant un passage traversant pour le bout commun L.
The figure 3 shows in perspective the bar of the invention where we find the elements described above, and furthermore the following elements:
  • two elbow sleeves 2C and 2D for the passage of the cables 5 and 6, respectively;
  • two longitudinal threaded rods 2E and 2F, penetrating into the bar 2 at the respective ends thereof and intended for clamping / locking the ends of the bar;
  • a radial sleeve 10, making a through passage for the common end L.

Le système de l'invention, pour le raccourcissement / allongement des câbles 5 et 6, est disposé à l'intérieur de la barre et est décrit ci-après au regard de la figure 4, dans un premier temps, montrant une forme de réalisation.The system of the invention, for the shortening / elongation of the cables 5 and 6, is arranged inside the bar and is described below with regard to the figure 4 , at first, showing an embodiment.

On retrouve sur la figure 4 les câbles arrière 5 et 6, les deux câbles avant 3 et 4. La barre 2 de l'invention est constituée d'un cylindre creux, en métal, ou en matériau composite et par exemple du carbone, et de longueur d'environ 30 à 60 cm pour un diamètre d'environ 20 à 30 mm. La barre est représentée sur la figure 3, en coupe longitudinale et en « écorché », montrant ainsi l'intérieur.We find on the figure 4 the rear cables 5 and 6, the two front cables 3 and 4. The bar 2 of the invention consists of a hollow cylinder, made of metal, or composite material and for example carbon, and about 30 at 60 cm for a diameter of about 20 to 30 mm. The bar is represented on the figure 3 , in longitudinal section and in "skinned", thus showing the interior.

La barre comporte à ses deux extrémités deux manchons 7 et 8 d'obturation, et sensiblement en son centre, un manchon fixe 9.The bar has at its two ends two sleeves 7 and 8 shutter, and substantially at its center, a fixed sleeve 9.

Les câbles avant 3 et 4 traversent la barre 2, sensiblement en son centre, au travers d'une ouverture 10A créée dans la barre 2, destinée à recevoir le manchon 10 (non représenté) de la figure 3, pour permettre le passage desdits câbles au-delà de la barre, vers le harnais (non représenté) que porte l'utilisateur/trice. Plus précisément, les câbles avant 3 et 4 traversent la barre dans un fourreau (non représenté pour des raisons de clarté) guidant ces derniers. Le fourreau est disposé diamétralement sur la barre au niveau d'une échancrure délimitant l'ouverture 10 centrale.The front cables 3 and 4 pass through the bar 2, substantially at its center, through an opening 10A created in the bar 2, intended to receive the sleeve 10 (not shown) of the figure 3 , to allow the passage of said cables beyond the bar, to the harness (not shown) worn by the user. Specifically, the front cables 3 and 4 pass through the bar in a sheath (not shown for clarity) guiding them. The sleeve is arranged diametrically on the bar at a notch defining the central opening.

Dans la barre, sont également prévus :

  • Un coulisseau 11 de forme complémentaire apte à se déplacer dans la barre longitudinalement ;
  • Une réglette longitudinale 12, rendue solidaire dudit coulisseau 11, et présentant une longueur d'environ 17 cm, et comportant une pluralité de trous 13, 14, etc. cylindriques et régulièrement espacés, sur une partie de la longueur de la réglette ;
  • Un vérin à gaz 15 comprenant un corps de vérin 16 à l'intérieur duquel se déplace un piston 17 dont l'extrémité distale est fixée au manchon fixe central 9 ;
  • Un bloc fonctionnel 18 fixe, disposé à proximité de l'ouverture 10 de passage des câbles avant, et comportant un mécanisme d'actionnement 18 (détaillé ultérieurement) d'un tenon 19 mobile diamétralement, et dont l'extrémité est apte à traverser l'un des trous prévus sur la réglette 12.
In the bar, are also planned:
  • A slider 11 of complementary shape adapted to move in the bar longitudinally;
  • A longitudinal strip 12, secured to said slider 11, and having a length of about 17 cm, and having a plurality of holes 13, 14, etc. cylindrical and regularly spaced, over a part of the length of the strip;
  • A gas cylinder 15 comprising a cylinder body 16 inside which moves a piston 17 whose distal end is fixed to the central fixed sleeve 9;
  • A fixed functional block 18, disposed near the opening 10 for the passage of the front cables, and comprising an actuating mechanism 18 (detailed later) of a peg 19 movable diametrically, and whose end is adapted to traverse the one of the holes provided on the slide 12.

Le câble arrière gauche 5 traverse le manchon d'extrémité gauche 7, pour s'engager, à l'intérieur de la barre 2, sur une poulie de guidage, qui n'est pas représentée, disposée à l'intérieur du coulisseau 11. L'extrémité du câble arrière gauche 5 est reliée au manchon d'extrémité gauche 7.The left rear cable 5 passes through the left end sleeve 7, to engage, inside the bar 2, on a guide pulley, which is not shown, disposed inside the slider 11. The end of the left rear cable 5 is connected to the left end sleeve 7.

Ainsi, à l'intérieur de la barre, le câble 5 forme deux brins parallèles 5A et 5B entre le manchon d'extrémité 7 et le coulisseau 11.Thus, inside the bar, the cable 5 forms two parallel strands 5A and 5B between the end sleeve 7 and the slider 11.

Le câble arrière droit 6 passe au travers du manchon d'obturation 8, puis traverse intégralement la barre par l'intérieur, et passe par une poulie de renvoi (non représentée) d'axe diamétral et prévue dans le manchon d'obturation 7. Le câble forme à la sortie de cette poulie un premier brin 6A qui passe autour de l'autre poulie de renvoi prévue sur le coulisseau 11, puis, forme un second brin 6B dont l'extrémité distale est fixée au manchon d'extrémité 7.The right rear cable 6 passes through the sealing sleeve 8, then completely crosses the bar from the inside, and passes through a return pulley (not shown) of diametrical axis and provided in the closure sleeve 7. The cable forms at the output of this pulley a first strand 6A which passes around the other deflection pulley provided on the slider 11, then forms a second strand 6B whose distal end is fixed to the end sleeve 7.

La poulie prévue dans le coulisseau 11 est donc commune aux deux câbles arrière 5 et 6.The pulley provided in the slider 11 is therefore common to the two rear cables 5 and 6.

La réglette 12 est solidaire par son extrémité 12B (opposée à l'extrémité 12A solidaire du coulisseau 11) du manchon central fixe 9, par un câble ou filin additionnel 20. Ce dernier passe par une poulie de renvoi (non représentée) d'axe diamétral et prévue dans un second coulisseau 21 solidaire de l'extrémité du vérin 16 tournée vers le manchon d'extrémité 8.The slider 12 is secured by its end 12B (opposite the end 12A secured to the slider 11) of the fixed central sleeve 9, by an additional cable or rope 20. The latter passes through a return pulley (not shown) axis diametrical and provided in a second slide 21 secured to the end of the jack 16 turned towards the end sleeve 8.

Le filin additionnel 20 comporte ainsi :

  • un premier brin 20A reliant l'extrémité 12 B de la barrette 12 et la poulie du second coulisseau 21 ;
  • un second brin 20B reliant ladite poulie ou manchon central fixe 9.
The additional rope 20 thus comprises:
  • a first strand 20A connecting the end 12 B of the bar 12 and the pulley of the second slider 21;
  • a second strand 20B connecting said fixed central pulley or sleeve 9.

Le piston à gaz 15 est du type connu en soi et est apte à exercer, en fonction de la position relative de la tige du piston 17 et du corps de vérin 16, une force de rappel sur la réglette 12. En effet, cette dernière est reliée, par le filin additionnel 20 de longueur totale fixe à un point fixe de la barre, c'est-à-dire le manchon central 9.The gas piston 15 is of the type known per se and is able to exert, as a function of the relative position of the rod of the piston 17 and the cylinder body 16, a restoring force on the strip 12. In fact, the latter is connected by the additional rope 20 of fixed total length to a fixed point of the bar, that is to say the central sleeve 9.

Il est maintenant fait référence aux figures 5A à 5D montrant la barre 2 de la figure 4 suivant quatre étapes ou positions des éléments mobiles disposés à l'intérieur de la barre, en cours d'utilisation de cette dernière associée à une aile.Reference is now made to Figures 5A to 5D showing bar 2 of the figure 4 following four steps or positions of the movable elements disposed within the bar, in use of the latter associated with a wing.

Sur la figure 5A, le piston 17 est en extension maximale. En conséquence, le second coulisseau 21 est dans sa position extrême, c'est-à-dire en butée contre le manchon d'extrémité 8. Cette position correspond à celle de la figure 3.On the Figure 5A the piston 17 is in maximum extension. As a result, the second slider 21 is in its extreme position, that is to say in abutment against the end sleeve 8. This position corresponds to that of the figure 3 .

Sur la figure 5B, sous l'action de forces de traction exercées par l'aile (non représentée) et donc sur les câbles arrière 5 et 6, les deux coulisseaux 11 et 21 sont déplacés vers la gauche de la figure. Le premier coulisseau 11 entraîne ainsi la translation de la réglette 12 vers la gauche. Ce faisant, les brins 5A, 5B, 6A et 6B sont raccourcis puisque la distance entre le manchon d'extrémité 7 et le coulisseau 11 est diminuée.On the Figure 5B under the action of traction forces exerted by the wing (not shown) and thus on the rear cables 5 and 6, the two slides 11 and 21 are moved to the left of the figure. The first slider 11 thus causes the slide 12 to be shifted to the left. In doing so, the strands 5A, 5B, 6A and 6B are shortened since the distance between the end sleeve 7 and the slider 11 is decreased.

En fin de course, on aboutit à la position représentée sur la figure 5C, le coulisseau 11 butant contre le manchon d'extrémité 7, et la tige de piston 17 étant rentrée quasiment totalement à l'intérieur du corps de vérin 16.At the end of the race, we reach the position represented on the Figure 5C , the slider 11 abuts against the end sleeve 7, and the piston rod 17 is retracted almost completely inside the cylinder body 16.

Le déplacement des éléments mobiles à l'intérieur de la barre conduit à allonger / raccourcir les câbles arrière 5 et 6, de manière à régler le comportement de l'aile, sa puissance, son inclinaison, etc.Moving the movable elements inside the bar leads to lengthen / shorten the rear cables 5 and 6, so as to adjust the behavior of the wing, its power, its inclination, etc.

Par les deux poulies de renvoi prévues dans les coulisseaux respectifs 11 et 21, on constate qu'une distance donnée « D » d'allongement / raccourcissement des câbles 5 et 6 conduit à un déplacement « d » en translation des éléments mobiles de la barre, tel que : d = D / 4.By the two return pulleys provided in the respective sliders 11 and 21, it is found that a given distance "D" of elongation / shortening of the cables 5 and 6 leads to a displacement "d" in translation of the movable elements of the bar , such that: d = D / 4.

Ceci permet de limiter l'encombrement de la barre, tout en bénéficiant d'une amplitude d'allongement / raccourcissement des câbles, appréciable et suffisante pour l'utilisateur/trice.This makes it possible to limit the bulk of the bar, while benefiting from an amplitude of elongation / shortening of the cables, which is appreciable and sufficient for the user.

Il est maintenant fait référence aux figures 6A à 6C, montrant de manière schématique les forces exercées sur la réglette 12 et donc sur les câbles 5 et 6. L'ensemble filin additionnel 20 / coulisseau 21 / piston à gaz 15 est représenté de manière schématique par un ressort, tandis que les manchons d'extrémité 7 et 9 sont symbolisés par des attaches fixes.Reference is now made to Figures 6A to 6C , schematically showing the forces exerted on the strip 12 and thus on the cables 5 and 6. The additional wire assembly 20 / slide 21 / gas piston 15 is represented by schematically by a spring, while the end sleeves 7 and 9 are symbolized by fixed fasteners.

Sur la figure 6A, on a représenté une position dite au repos, c'est-à-dire que la force FA, exercée par le vérin à gaz 15 sur la réglette 12, est supérieure en intensité à la force GA exercée par les câbles arrière 5 et 6 sur la réglette 12. Les forces FA et GA sont dans la direction de l'axe longitudinal de la base, mais sont de sens opposés.On the Figure 6A , a rest position is shown, that is to say that the force FA, exerted by the gas cylinder 15 on the strip 12, is greater in intensity than the force GA exerted by the rear cables 5 and 6 on the slide 12. The forces FA and GA are in the direction of the longitudinal axis of the base, but are in opposite directions.

Le tenon 19 fait saillie et pénètre dans le trou 13 de la réglette 12, bloquant celle-ci en translation. Le vérin à gaz 15 exerce ainsi une force de rappel sur la réglette 12.The post 19 protrudes and enters the hole 13 of the slide 12, blocking the latter in translation. The gas cylinder 15 thus exerts a restoring force on the strip 12.

Si l'utilisateur/trice appuie sur le bouton poussoir (non représenté et décrit ultérieurement) du mécanisme d'actionnement 18, associé au tenon 19, il fait ainsi rentrer celui-ci à nouveau dans la barre 12, libérant alors la réglette 12 qui peut donc se mouvoir en translation.If the user presses the pushbutton (not shown and described later) of the actuating mechanism 18, associated with the pin 19, it thus returns it again in the bar 12, then releasing the strip 12 which can therefore move in translation.

Du fait que la force FA est d'intensité supérieure à la force GA, la réglette se déplace donc vers la droite jusqu'à une position d'équilibre représentée sur la figure 5B, où la réglette est soumise à deux forces FB (de rappel du vérin) et GB (des câbles arrières) d'égales intensités et de sens opposé.Since the force FA is of greater intensity than the force GA, the slider moves to the right to a position of equilibrium represented on the Figure 5B , where the slider is subjected to two forces FB (cylinder return) and GB (rear cables) of equal intensities and opposite direction.

Cette situation correspond à une configuration de l'aile dite « légèrement bordée ».This situation corresponds to a configuration of the so-called "slightly lined" wing.

L'utilisateur/trice peut, si il/elle le souhaite, réenclencher le tenon 19 de manière à ce qu'il bloque dans cette position d'équilibre, la réglette 12.The user can, if he / she wishes, reset the pin 19 so that it blocks in this equilibrium position, the strip 12.

Si au contraire l'utilisateur/trice fait en sorte que le tenant 19 ne bloque pas la translation de la réglette 12, alors les forces exercées par les câbles arrière deviennent supérieures à la force de rappel du vérin à gaz. On aboutit alors à la position représentée sur la figure 5C, où la force GC exercée sur la réglette par les câbles arrière, est supérieure à la force de rappel FC exercée par le vérin à gaz 15. Sur la figure 6B, la réglette 12 est à l'équilibre, car soumise à deux forces FB et GB de même intensité, et de sens opposé, suivant la direction longitudinale de la barre. Cette position d'équilibre est atteinte lorsque l'utilisateur/trice « borde » légèrement l'aile, c'est-à-dire qu'une tension modérée est exercée sur la barre par l'aile.If instead the user makes sure that the holder 19 does not block the translation of the slide 12, then the forces exerted by the rear cables become greater than the restoring force of the gas cylinder. We then arrive at the position represented on the Figure 5C , where the force GC exerted on the slide by the rear cables, is greater than the restoring force FC exerted by the gas cylinder 15. On the Figure 6B , the strip 12 is in equilibrium, because subjected to two forces FB and GB of the same intensity, and opposite direction, in the longitudinal direction of the bar. This equilibrium position is reached when the user "edges" slightly the wing, that is to say that a moderate tension is exerted on the bar by the wing.

Les figures 7A et 7B sont des vues en perspective et en « éclaté », d'une partie de la barre, montrant le mécanisme d'actionnement 18 associée au tenon mobile 19 coopérant avec les trous 13, 14, etc. de la réglette 12, afin de bloquer ou débloquer celle-ci dans son mouvement de translation longitudinale.The Figures 7A and 7B are views in perspective and "exploded" of a portion of the bar, showing the actuating mechanism 18 associated with the movable pin 19 cooperating with the holes 13, 14, etc. of the strip 12, in order to block or unblock it in its longitudinal translation movement.

Ledit mécanisme d'actionnement 18 comporte :

  • un bouton poussoir 22 accessible depuis l'extérieur de la barre au travers d'une ouverture ;
  • un ressort de compression 23 diamétral ;
  • un petit vérin hydraulique 24 lié audit tenon 19 de blocage pour translater ce dernier entre une première position active (figure 7A) où il pénètre dans un des trous de la réglette, et une seconde position rétractée (figure 7B) où il laisse libre le coulissement de la réglette ;
  • une tige 25 reliée au ressort 23 et au vérin 24 apte à commander ce dernier, par actionnement sur le ressort.
Said actuating mechanism 18 comprises:
  • a push button 22 accessible from outside the bar through an opening;
  • a compression spring 23 diametral;
  • a small hydraulic jack 24 connected to said blocking pin 19 to translate the latter between a first active position ( Figure 7A ) where it enters one of the holes in the slide, and a second retracted position ( Figure 7B where it leaves free the sliding of the ruler;
  • a rod 25 connected to the spring 23 and the cylinder 24 adapted to control the latter, by actuation on the spring.

L'axe de translation du tenon de blocage 19 est sensiblement orthogonal d'une part à l'axe de translation du bouton poussoir 22 et d'autre part au plan de translation de la réglette. Ainsi, l'utilisateur/trice peut actionner ce dernier avec un pouce, par le dessous de la barre faisant sensiblement face au sol.The axis of translation of the locking pin 19 is substantially orthogonal on the one hand to the axis of translation of the push button 22 and on the other hand to the translation plane of the strip. Thus, the user can operate the latter with a thumb, from below the bar substantially facing the ground.

La figure 8 montre une vue en perspective et en écorché une partie de la barre de la figure 4 et montrant notamment une partie du vérin 15 et du système de renvoi, le manchon 10 traversant pour le passage des câbles, et les moyens de blocage/déblocage de la réglette (figures 7A et 7B).The figure 8 shows a perspective view and cut off some of the bar from the figure 4 and showing in particular a portion of the jack 15 and the deflection system, the sleeve 10 passing through for the passage of the cables, and the locking / unlocking means of the strip ( Figures 7A and 7B ).

La figure 9 montre la barre en perspective et en écorché, selon une autre forme de réalisation, sans réglette et à l'aide d'un vérin 150 dit « autobloquant ».The figure 9 shows the bar in perspective and cutaway, according to another embodiment without ruler and using a cylinder 150 called "self-locking".

Le vérin autobloquant est manoeuvré par l'utilisateur/trice, via un mécanisme à came 26, décrit plus loin, relié à un bouton poussoir 22 associé à un ressort de compression 23 (similaires à ceux de la réalisation des figures 7A et 7B).The self-locking cylinder is operated by the user, via a cam mechanism 26, described below, connected to a push button 22 associated with a compression spring 23 (similar to those of the embodiment of the invention). Figures 7A and 7B ).

La figure 10 montre une vue de détail du système de blocage 26 associé au vérin autobloquant 150.The figure 10 shows a detailed view of the locking system 26 associated with the self-locking jack 150.

Le bouton poussoir 22 fait corps avec une tige 27 déplaçable en translation diamétrale et pourvue d'un biseau 28. Une patte 29 porte contre le biseau 28, la patte étant elle-même solidaire d'un bras longitudinal 30 (passant devant le manchon 10) qui est relié par une fourche 31 au piston 32 du vérin auto bloquant 150.The push-button 22 is integral with a rod 27 which is displaceable in diametrical translation and provided with a bevel 28. A lug 29 bears against the bevel 28, the lug being itself secured to a longitudinal arm 30 (passing in front of the sleeve 10 ) which is connected by a fork 31 to the piston 32 of the self-locking jack 150.

Lorsque l'utilisateur/trice appui sur le bouton poussoir 22, la tige 27 se déplace en translation, ce qui provoque, par le biseau 28 repoussant alors la patte diamétrale 29, en translation longitudinale. Ceci entraine, via le bras 30 et la fourche 31, le déplacement du piston 32 du vérin.When the user pushes on the push button 22, the rod 27 moves in translation, which causes, by the bevel 28 then pushing the diametral lug 29, in longitudinal translation. This causes, via the arm 30 and the fork 31, the displacement of the piston 32 of the jack.

Ce dernier est alors soumis aux forces de traction exercée par les câbles 5 et 6, comme montré schématiquement sur la figure 12B.The latter is then subjected to the tensile forces exerted by the cables 5 and 6, as shown schematically on the figure 12B .

Le vérin autobloquant 150 est du type connu de l'homme de l'art, et dit auto bloquant en ce que son piston intérieur reste bloqué en translation tant qu'une action de déblocage n'est pas appliquée sur le piston, par le biais du bouton poussoir, comme décrit ci-dessus.The self-locking cylinder 150 is of the type known to those skilled in the art, and says self locking in that its inner piston remains locked in translation as a release action is not applied to the piston, through push button, as described above.

Lorsque l'utilisateur/trice relâche le bouton poussoir, le piston 32 du vérin n'est plus soumis à la force de translation longitudinale (par la cinétique expliquée ci-dessus), et alors le piston se bloque à nouveau.When the user releases the push button, the piston 32 of the cylinder is no longer subjected to the longitudinal translation force (by the kinetics explained above), and then the piston is blocked again.

La figure 11 est une vue en perspective en « écorché » d'une variante de réalisation de la figure 9, avec vérin autobloquant, et muni d'un système de poulies à quatre renvois respectivement 210 (du côté de la chambre fixe du vérin 150) et 110 du côté opposé, au-delà du manchon 10).The figure 11 is a perspective view in "skinned" of a variant embodiment of the figure 9 , with self-locking cylinder, and provided with a system of pulleys with four returns respectively 210 (on the side of the fixed chamber of the cylinder 150) and 110 of the opposite side, beyond the sleeve 10).

La configuration de la figure 11 est représentée schématiquement sur la figure 12C.The configuration of the figure 11 is schematically represented on the figure 12C .

Les figures 12A, 12B et 12C illustrent de manière schématique les trois formes de réalisation de la barre, et les moyens d'allongement / raccourcissement des câbles, respectivement de la figure 4 (vérin et réglette), la figure 9 (sans réglette et avec vérin autobloquant) et la figure 11 (sans réglette, avec vérin autobloquant et poulies à quatre renvois).The Figures 12A, 12B and 12C schematically illustrate the three embodiments of the bar, and the means of elongation / shortening of the cables, respectively the figure 4 (cylinder and ruler), the figure 9 (without ruler and with self-locking cylinder) and the figure 11 (without ruler, with self-locking cylinder and four-speed pulleys).
