Selon une caractéristique de l'invention, les deux étriers sont diamétralement opposés par rapport à l'axe en étant disposés de part et d'autre de la direction d'extension du bras support avec un angle d'inclinaison prédéterminé.According to a characteristic of the invention, the two stirrups are diametrically opposite with respect to the axis by being arranged on either side of the direction of extension of the support arm with a predetermined angle of inclination.
Selon un mode de réalisation préférentiel, les moyens de déblocage de l'enrouleur sont fixés à des plots de guidage des lignes. Ils comportent des gaines élastiques de passage du fil des lignes et destinées à coopérer avec des crochets situés sur des étriers pour occuper soit une position de verrouillage unidirectionnel, soit une position de déverrouillage, respectivement pour empêcher ou autoriser le dévidage de l'enroulement du fil sous l'effet de traction exercé sur des lignes par le cerf-volant, le passage de la position de verrouillage vers la position de déverrouillage s'effectuant manuellement par un déplacement simultané des deux gaines ou des lignes hors de la trajectoire des crochets. Les plots font saillie de la barre de préhension, et comportent des moyens de réglage pour ajuster l'écartement en fonction de la voilure du cerf-volant. Selon une autre caractéristique de l'invention, une manivelle est portée par au moins un étrier pour autoriser le rembobinage manuel du fil sur l'enrouleur suite à un mouvement de rotation inverse à celui s'opérant lors du dévidage.According to a preferred embodiment, the means for unlocking the reel are fixed to line guide pads. They include elastic sheaths for the passage of the line wire and intended to cooperate with hooks located on stirrups to occupy either a unidirectional locking position or an unlocking position, respectively to prevent or allow the unwinding of the winding of the wire under the pulling effect exerted on lines by the kite, the passage from the locking position to the unlocking position is effected manually by a simultaneous movement of the two sheaths or lines outside the trajectory of the hooks. The studs protrude from the grip bar, and include adjustment means for adjusting the spacing as a function of the kite's airfoil. According to another characteristic of the invention, a crank is carried by at least one stirrup to authorize the manual rewinding of the wire on the reel following a rotation movement opposite to that occurring during the unwinding.

Description d'un mode de réalisation préférentiel.Description of a preferred embodiment.
En référence aux figures, un dispositif d'enroulement 10 du fil souple de retenue d'un cerf-volant comporte une barre de préhension 12 équipée dans la partie centrale d'un enrouleur 14 rotatif permettant d'enrouler ou de dérouler progressivement la longueur d'une paire de lignes 16A, 16B gauche et droite du fil de retenue.With reference to the figures, a device 10 for winding the flexible wire for retaining a kite comprises a gripping bar 12 fitted in the part central of a rotary winder 14 for winding or progressively unwinding the length of a pair of lines 16A, 16B left and right of the retaining wire.
L'enrouleur 14 comprend un bras de support 18 rectiligne, lequel est monté à rotation libre sur un axe 20 fixe s'étendant perpendiculairement à la barre de préhension 12. Deux étriers 22A, 22B conformés selon des fourches en U, sont fixés aux extrémités opposées du bras de support 18 rotatif pour assurer la mise en place et le stockage du fil de retenue. Au moins un des étriers 22A, 22B est doté d'une manivelle 24 autorisant le rembobinage manuel des lignes 16A, 16B gauche et droite du fil de retenue lorsque l'enrouleur 14 tourne dans le sens des aiguilles d'une montre.The reel 14 comprises a straight support arm 18, which is mounted for free rotation on a fixed axis 20 extending perpendicular to the gripping bar 12. Two stirrups 22A, 22B shaped according to U-shaped forks, are fixed at the ends opposite support arm 18 rotating to ensure the establishment and storage of the retaining wire. At least one of the stirrups 22A, 22B is provided with a crank 24 authorizing the manual rewinding of the lines 16A, 16B left and right of the retaining wire when the reel 14 rotates clockwise.
Les deux étriers 22A, 22B diamétralement opposés par rapport à l'axe 20 de l'enrouleur 14, sont disposés de part et d'autre de la direction d'extension du bras de support 18 avec un angle d'inclinaison prédéterminé, par exemple de l'ordre de 40°.The two stirrups 22A, 22B diametrically opposite with respect to the axis 20 of the reel 14, are arranged on either side of the direction of extension of the support arm 18 with a predetermined angle of inclination, for example of the order of 40 °.
Le mouvement de rotation de l'enrouleur 14 peut être contrôlé au moyen d'un frein 26 comprenant un premier flasque de freinage 28A solidaire du bras de supportThe rotational movement of the reel 14 can be controlled by means of a brake 26 comprising a first braking flange 28A secured to the support arm
18 rotatif, et coopérant par friction avec un deuxième flasque de freinage 28B fixé à la barre de préhension 12. Les deux flasques de freinage 28A, 28B sont traversés par l'axe 20, dont l'extrémité filetée est dotée d'un écrou 30 de serrage permettant de moduler manuellement la force de friction entre les deux flasques 28A, 28B. Une rondelle 31 anti-rotation est interposée entre l'écrou 30 et la barre de préhension 12 pour empêcher la rotation de l'axe 20 lors du réglage du frein 26.18 rotating, and cooperating by friction with a second braking flange 28B fixed to the gripping bar 12. The two braking flanges 28A, 28B are crossed by the axis 20, the threaded end of which is provided with a nut 30 clamp for manually modulating the friction force between the two flanges 28A, 28B. An anti-rotation washer 31 is interposed between the nut 30 and the grip bar 12 to prevent rotation of the axis 20 when the brake 26 is adjusted.
Le guidage des lignes 16A, 16B s'effectue au moyen de deux plots 32A, 32 B faisant saillie de la barre de préhension 12 en s'étendant parallèlement à l'axe 20. Le fil peut coulisser autour d'axes 34 ménagés à la partie supérieure des plotsThe lines 16A, 16B are guided by two studs 32A, 32 B projecting from the gripping bar 12, extending parallel to the axis 20. The wire can slide around axes 34 arranged at the upper part of the studs
32A, 32B. En fonction de la voilure du cerf-volant, l'écartement des deux plots 32A, 32B est réglable le long de la direction longitudinale de la barre de préhension 12. Les axes sont positionnés dans un plan parallèle à la barre de préhension 12 et passant au voisinage des crochets 38A, 38B.32A, 32B. Depending on the wing size of the kite, the spacing of the two studs 32A, 32B is adjustable along the longitudinal direction of the bar. gripping 12. The axes are positioned in a plane parallel to the gripping bar 12 and passing in the vicinity of the hooks 38A, 38B.
Chaque plot 32A, 32B peut être pourvu d'une gaine 36A, 36B élastique pour le passage du fil de retenue, lequel est enroulé sur l'enrouleur 14 placé entre les plotsEach pad 32A, 32B can be provided with an elastic sheath 36A, 36B for the passage of the retaining wire, which is wound on the reel 14 placed between the pads
32A, 32B. Les gaines 36A, 36B évitent l'usure des fils sur les crochets 38A, 38B, et constituent des ressorts coopérant avec des crochets 38A, 38B de verrouillage unidirectionnel, lesquels sont solidaires des étriers 22A, 22B.32A, 32B. The sheaths 36A, 36B prevent wear of the wires on the hooks 38A, 38B, and constitute springs cooperating with hooks 38A, 38B of unidirectional locking, which are integral with the stirrups 22A, 22B.
Dans la position de verrouillage unidirectionnel, les gaines 36A, 36B interfèrent avec les crochets 38A, 38B en constituant des cliquets anti-retour qui empêchent le dévidage de l'enroulement 40 du fil sous l'effet de traction (flèche T, figure 3) exercé sur les lignes 16A, 16B par le cerf-volant. L'enrouleur 14 reste fixe en étant bloqué en rotation dans le sens inverse des aiguilles d'une montre.In the unidirectional locking position, the sheaths 36A, 36B interfere with the hooks 38A, 38B by constituting non-return pawls which prevent the unwinding of the winding 40 of the wire under the pulling effect (arrow T, FIG. 3) exerted on lines 16A, 16B by the kite. The reel 14 remains fixed while being locked in rotation in the anticlockwise direction.
Par contre, l'enrouleur 14 n'est pas bloqué pour le rembobinage du fil lors de la rotation inverse au moyen de la manivelle 24 (flèche R, figure 4).On the other hand, the winder 14 is not blocked for rewinding the wire during the reverse rotation by means of the crank 24 (arrow R, FIG. 4).
Le déblocage de l'enrouleur 14 dans le sens inverse des aiguilles d'une montre est rendu possible par un déplacement manuel simultané des gaines 36A, 36B vers une position de déverrouillage (flèche F1 , figure 6). Les crochets 38A, 38B des deux étriers 22A, 22B sont alors libérés en autorisant le dévidage de l'enroulement 40 sous l'effet de traction T exercé sur les lignes 16A, 16B.The unlocking of the reel 14 anticlockwise is made possible by simultaneous manual movement of the sheaths 36A, 36B towards an unlocking position (arrow F1, FIG. 6). The hooks 38A, 38B of the two stirrups 22A, 22B are then released by authorizing the unwinding of the winding 40 under the pulling effect T exerted on the lines 16A, 16B.
Le relâchement des gaines 36A, 36B provoque le rappel vers la position de verrouillage unidirectionnel provoquant le blocage automatique de l'enrouleur 14 lors d'un demi-tour complet.The release of the sheaths 36A, 36B causes the return to the unidirectional locking position causing the automatic rewinding of the reel 14 during a complete half-turn.
L'enroulement 40 du fil autour des deux étriers 22A, 22B de l'enrouleur 14 présente une forme sensiblement oblongue ou ovoïde, et a tendance à se positionner dans la direction longitudinale de la barre de préhension 12 lorsque les étriers 22A, 22B viennent en butée contre les gaines 36A, 36B. L'enrouleur 14 ayant un bras de support 18 d'une longueur de 35cm correspond à une bobine ronde conventionnelle de 22 cm de diamètre. Il en résulte un gain d'encombrement, et une grande capacité de stockage du fil de retenue.The winding 40 of the wire around the two stirrups 22A, 22B of the reel 14 has a substantially oblong or ovoid shape, and tends to be positioned in the longitudinal direction of the grip bar 12 when the stirrups 22A, 22B come in stop against sheaths 36A, 36B. The reel 14 having a support arm 18 with a length of 35cm corresponds to a reel conventional round 22 cm in diameter. This results in a gain in size, and a large storage capacity of the retaining wire.
Il est clair que les deux gaines 36A, 36B élastiques pour le passage du fil vers l'enrouleur 14 peuvent être réalisées par tout autre organe de guidage permettant de libérer progressivement la longueur de ligne souhaitée par le pilote du cerf- volant. It is clear that the two elastic sheaths 36A, 36B for the passage of the wire towards the reel 14 can be produced by any other guide member making it possible to gradually release the length of line desired by the pilot of the kite.
