La présente invention concerne un dispositif de contrôle pour cerf-volant de traction, il est constitué d'une barre centrale horizontale dont l'extrémité arrière est prolongée d'un élément s'élargissant progressivement vers l'arrière du dispositif. L'extrémité avant de la barre centrale est fixée à la partie étroite d'une plaque rigide horizontale. Cette plaque s'élargit progressivement vers Pavant du dispositif. Une poignée de préhension transversale est solidaire de l'extrémité avant de la plaque rigide. Au moins trois lignes de commande d'une aile de traction sont fixées sur le dispositif afin d'en assurer le contrôle, une à l'avant, tes deux autres aux extrémités latérales de la partie arrière. L'utilisation s'effectue principalement avec des lignes courtes.The present invention relates to a control device for traction kite, it consists of a horizontal central bar whose rear end is extended by an element gradually widening towards the rear of the device. The front end of the center bar is attached to the narrow portion of a rigid horizontal plate. This plate widens progressively towards the front of the device. A transverse grip is secured to the front end of the rigid plate. At least three control lines of a traction wing are attached to the device for control, one at the front, the other two at the lateral ends of the rear portion. The use is mainly with short lines.
Les systèmes à quatre lignes utilisés traditionnellement pour contrôler les cerfs-volants de traction sont composés d'une barre de préhension simple que l'utilisateur tient à bout de bras et sur laquelle sont fixées les lignes de commande de l'aile de traction. Généralement les deux lignes arrière sont fixées aux extrémités de la barre et les deux lignes avant sont liées à un cordon unique qui traverse un trou ou un filoir situé au centre de ladite barre. La partie basse du cordon est fixée au harnais de l'utilisateur. Ce dernier pousse ou tire la barre pour modifier l'incidence du cerf-volant. Un dispositif de largage manuel est prévu à la base du cordon pour se libérer totalement de l'aile. Ce système de commande équipe l'ensemble des ailes gonflables et une partie des ailes à caissons munies d'un système « border/choquer ». Les lignes avant des ailes à caissons sans « border/choquer » dirigées à l'aide d'une barre de contrôle sont généralement fixées directement à la barre. Les fonctions et les configurations des lignes de commande sur barre unique peuvent néanmoins présenter quelques variantes notamment lorsque de nouveaux systèmes de sécurité y sont adaptés.The four-line systems traditionally used to control pull kites are composed of a simple gripping bar which the user holds at arm's length and on which the control lines of the traction wing are fixed. Generally the two back lines are attached to the ends of the bar and the two front lines are connected to a single bead that passes through a hole or a wire located in the center of said bar. The lower part of the cord is attached to the user's harness. The latter pushes or pulls the bar to change the kite's impact. A manual release device is provided at the base of the cord to release completely from the wing. This control system equips all of the inflatable wings and part of the coffered wings equipped with a "border / shock" system. The front lines of coffered wings without "border / shock" directed with a control bar are usually attached directly to the bar. The functions and configurations of the single-bar control lines can nevertheless have some variants, especially when new security systems are adapted to them.
Un autre moyen de contrôle consiste à relier les deux lignes de commande du bord d'attaque aux extrémités supérieures de deux petites barres verticales coudées. Les lignes de commande du bord de fuite sont fixées aux extrémités inférieures des deux barres de contrôle. L'utilisateur tient une barre dans chaque main, il effectue des mouvements avec ses poignets pour diriger, reprendre de la puissance, freiner ou poser son cerf-volant. Ces petites barres verticales, appelées communément « poignées », sont essentiellement utilisées avec les ailes à caissons. Dans certains cas de figure, elles peuvent être fixées aux extrémités d'une barre de préhension horizontale. Les systèmes de contrôle décrits ci-dessus présentent plusieurs inconvénients.Another means of control is to connect the two control lines of the leading edge to the upper ends of two small vertical bars bent. The control lines of the trailing edge are attached to the lower ends of the two control rods. The user holds a bar in each hand, he makes movements with his wrists to direct, regain power, brake or put his kite. These small vertical bars, commonly called "handles", are mainly used with the coffered wings. In some cases, they can be attached to the ends of a horizontal gripping bar. The control systems described above have several disadvantages.
Le dispositif du « border/choquer » de la barre de contrôle précitée nécessite d'être attaché en permanence à l'aile pour pouvoir agir sur * l'incidence. Si on se détache, le cerf-volant sera en position de puissance maximum et donc difficile à tenir à bout de bras. De plus, l'alignement de toutes les lignes de commande sur une barre unique ne permet pas de freiner ou stabiliser l'aile rapidement et efficacement.The device of the "border / shock" of the aforementioned control bar requires to be permanently attached to the wing to be able to act on the incidence. If we come off, the kite will be in maximum power position and therefore difficult to hold at arm's length. In addition, the alignment of all control lines on a single bar does not allow to brake or stabilize the wing quickly and efficiently.
L'obligation de garder une certaine longueur de lignes (entre 15 et 30 "*° mètres) laisse une marge de manœuvre nécessaire pour palier à ce déficit de contrôle. Cela permet d'effectuer des sinusoïdales pour s'équilibrer et reprendre de la puissance.The obligation to keep a certain length of lines (between 15 and 30 "* meters) leaves room for maneuver necessary to compensate for this lack of control.This allows to perform sinusoidal to balance and regain power .
D'autre part les ailes de petites et moyennes dimensions installées sur ce système sont trop réactives avec des lignes courtes ( inférieures à 15 mètres ~*£ environ ).On the other hand the wings of small and medium size installed on this system are too reactive with short lines (less than 15 meters ~ * £).
Les deux barres verticales présentent l'inconvénient d'être difficile à gérer sur un support mobile ou l'utilisateur se tient en équilibre car elles ne permettent pas au pilote de se stabiliser correctement. Par ailleurs le contrôle d'une aile de traction avec ce type de barres s'effectue essentiellement à la ~$° force des poignets. De nombreux pratiquants trouvent ce dispositif physique et délicat, même avec une barre horizontale reliant les deux poignées verticales.The two vertical bars have the disadvantage of being difficult to manage on a mobile support or the user is balanced because they do not allow the pilot to stabilize properly. In addition, the control of a traction wing with this type of bar is carried out essentially at ~ $ ° wrist strength. Many practitioners find this physical and delicate device even with a horizontal bar connecting the two vertical handles.
Le dispositif de contrôle selon l'invention permet de remédier à ces inconvénients et trouve son application dans de nombreux sports tractés par un cerf-volant comme le kitesurf, le kitesnow, le mountainboard, le buggy, le t?.T catakite etc.. il peut s'adapter à la plupart des ailes de traction du marché et permet de réduire considérablement la longueur des lignes de commande, responsable de nombreux accidents.The control device according to the invention overcomes these disadvantages and finds application in many sports towed by a kite such as kitesurf, kitesnow, mountainboard, buggy, t? .T catakite etc. .. It can be adapted to most traction wings on the market and considerably reduces the length of control lines, which is responsible for many accidents.

La description figure 4 et 4A représente le principe de fonctionnement, vu de profil, du réglage de l'incidence d'une aile gonflable (10) de type « bow » et d'une aile à caissons (27) (brides non représentées) sans système de « border/choquer », basé sur le pivotement du dispositif de contrôle. Description 4 and 4A represents the operating principle, seen in profile, of the adjustment of the incidence of an inflatable wing (10) of the "bow" type and of a caisson wing (27) (flanges not shown) without a "border / shock" system, based on the pivoting of the control device.
En poussant la partie arrière (fig. 4) de la barre centrale (1), la longueur initialement réglée des lignes avant (7) par rapport aux lignes arrière (6), qui correspond au réglage optimum de l'aile (10), s'en trouve modifiée. Le relâchement de la pression sur les lignes arrière (6) qui en résulte, réduit la 5 pression sur les brides (26) du bord de fuite (9) de l'aile gonflable (10) quiBy pushing the rear part (FIG 4) of the central bar (1), the length initially set of the front lines (7) with respect to the rear lines (6), which corresponds to the optimum setting of the wing (10), is modified. The resulting release of pressure on the rear lines (6) reduces the pressure on the flanges (26) of the trailing edge (9) of the inflatable wing (10) which
« ouvre » et devient moins puissante. Une poulie de renvoi (25) reliant les brides arrière (26) aux suspentes avant (28) solidaires du bord d'attaque (8) permet de démultiplier l'effet d'ouverture de l'aile (10). A l'inverse, Tirer la partie arrière de la barre centrale (1) vers soi permet de border plus ou moins l'aile (10) afin d'augmenter sa puissance."Opens" and becomes less powerful. A return pulley (25) connecting the rear flanges (26) to the front lines (28) integral with the leading edge (8) allows to increase the opening effect of the wing (10). Conversely, pulling the rear part of the central bar (1) towards you allows more or less to taper the wing (10) to increase its power.
Le fonctionnement du dispositif de contrôle (fig.4A) installé sur une aile à caissons (27) non munie d'un système de « border/choquer » diffère car le bord d'attaque (8), à l'inverse d'une aile gonflable (10), ne fait pas office de pivot. La puissance se règle alors en pliant plus ou moins le bord de fuite (9) de l'aile (27) -//" vers le bas. En tirant vers soi l'arrière de la barre centrale (1) du dispositif, on augmente la pression sur les lignes arrières (6), la puissance est plus importante. Le profil de l'aile (27) se déforme plus ou moins en fonction de la pression exercée sur l'arrière de la barre centrale (1).The operation of the control device (FIG. 4A) installed on a box wing (27) not equipped with a "border / shock" system differs because the leading edge (8), unlike a inflatable wing (10), does not act as pivot. The power is then adjusted by folding more or less the trailing edge (9) of the wing (27) - // " downwards, pulling towards the rear of the central bar (1) of the device. increases the pressure on the rear lines (6), the power is greater.The profile of the wing (27) deforms more or less depending on the pressure exerted on the rear of the central bar (1).
