Abstract

The rudder bar comprises ropes (6) surrounding a central rotating tube (4). Two lateral tubes (1) are separated from the central tube by two bearings (2). The kite lines (8) are fixed to the lateral tubes and to the upper ends of the rope. The lower ends of the rope are connected to the user. The kite power is managed by pushing or pulling the lateral tubes which rotate the central tube by the simultaneous unwinding and winding of the rope around the tube.

"\'Il L'invention concerne un palonnier pour cerf-volant de traction muni d'un système border, choquer. "\ 'It A joystick for traction kite with a border system shock.

Le système d'incidence variable utilisé actuellement pour réduire ou augmenter la traction d'un cerf-volant (brevet Legaignoux) est composé d'un palonnier comportant un trou central dans lequel coulisse une cordelette reliée d'un côté à l'utilisateur et de l'autre aux lignes du cerf-volant. The variable incidence system currently used to reduce or increase the traction of a kite (patent Legaignoux) is composed of a lifter having a central hole in which slides a cord connected at one end to the user and the other lines of the kite. Ce système comporte plusieurs inconvénients notamment une pratique plus physique du fait de l'absence de blocage des lignes arrières, ainsi qu'un manque de stabilité du palonnier, d'où un contrôle et une gestion de la puissance plus difficile (gestes parasites). This system has several drawbacks including increased physical practice because of the lack of blocking back lines and a lack of stability of the spreader, which control and difficult power management (parasites gestures).

Le système selon l'invention permet de remédier à ces inconvénients, il comporte en effet, selon une première caractéristique, un cordage entourant un tube central rotatif ainsi que deux tubes latéraux désolidarisés du tube central par deux roulements. The system according to the invention overcomes these drawbacks, it has in fact, according to a first feature, a rope around a rotatable central tube and two side tubes disconnected from the central tube by two bearings. Les lignes du cerf-volant sont fixées d'une part aux tubes latéraux et d'autre part aux extrémités supérieures du cordage. The lines of the kite are fixed on the one hand to the lateral tubes and the other at the upper ends of the rope. Les extrémités inférieures de ce cordage sont reliées à l'utilisateur. The lower ends of the string are connected to the user. Celui ci gère la force de traction en poussant ou en tirant les tubes latéraux, il entraîne ainsi la rotation du tube central obtenue par le déroulement et l'enroulement simultané du cordage autour dudit tube. This one manages the tensile force by pushing or pulling the side tubes, it thus causes rotation of the central tube obtained by the process and the simultaneous winding of the rope around said tube. Par ailleurs, lorsque l'utilisateur souhaite maintenir le palonnier dans une position donnée, il empoigne le tube central, empêchant ainsi la rotation de ce dernier. Furthermore, when the user wishes to maintain the lifter in a given position, it grabs the central tube, thereby preventing rotation of the latter. La force de rappel de l'utilisateur en opposition à la force de traction du cerf-volant bloque le cordage sur le palonnier. The restoring force of the user as opposed to the kite traction locks the rope on the spreader.

Selon des modes particuliers de réalisation : - Les extrémités du tube central peuvent comporter deux roulements. According to particular embodiments: - The ends of the central tube may have two bearings.

- Un cordage, dirigé par un ou des guides, peut être enroulé autour du palonnier. - A string, led by one or guides can be wrapped around the rudder.

- Les extrémités supérieures du cordage peuvent être fixées sur les lignes des avants du cerf- volant. - The upper ends of the rope may be attached to the lines of the front of the kite. Ces dernières coulissent à travers des oeillets situés sur le palonnier et se prolongent pour former les lignes des arrières. In recent slide through eyelets located on the lifter and extend to form the rear lines.

D'une manière générale, les éléments décrits ci-dessus peuvent être remplacés par des éléments similaires ayant la même fonction et permettant d'obtenir le même résultat. In general, the above described components can be replaced by similar elements having the same function and to obtain the same result. La présente invention n'est pas limitée aux modes de réalisations représentés et on peut apporter à ceux-ci de nombreux changements et modifications sans sortir du domaine de l'invention. The present invention is not limited to the embodiments shown and can be made to these many changes and modifications without departing from the scope of the invention.

Les dessins annexés illustrent l'invention : The accompanying drawings illustrate the invention:
La figure 1 représente le palonnier selon l'invention. 1 shows the joystick according to the invention.

La figure 2 représente la jonction du tube central et du tube latéral. 2 shows the junction of the central tube and the side tube.

La figure 3 représente le positionnement du cordage et des guides sur le tube central. 3 shows the positioning of the rope and guides on the central tube.

La figure 4 représente le palonnier dans une configuration spécifique des lignes. 4 shows the spreader in a specific configuration of the lines.

En référence à ces dessins, le palonnier comporte deux tubes latéraux (1) sur lesquels sont fixées les lignes (8) du cerf-volant. Referring to these drawings, the spreader comprises two lateral tubes (1) on which the lines are fixed (8) of the kite. Ils sont reliés à un tube central (4) par des tiges filtées (3). They are connected to a central tube (4) by filtées rods (3). Celles-ci se fixent dans des roulements (2) enchâssés aux extrémités du tube central (4). These are fixed in bearings (2) embedded at the ends of the central tube (4). Un cordage (6) dirigé par des guides (5) entoure le tube central (4). A rope (6) directed by guides (5) surrounds the central tube (4). Les extrémités inférieures du cordage (6) comportent un bout de harnais (7) relié à l'utilisateur. The lower ends of the rope (6) comprise a harness line (7) connected to the user. Les extrémités supérieures sont fixées aux lignes (8) du cerf-volant. The upper ends are attached to the lines (8) of the kite.

En configuration quatre lignes selon la figure 4, des oeillets (9) fixés sur les tubes latéraux (1) sont traversés par les lignes (8) reliant les avants et les arrières. Configuration four lines according to Figure 4, the eyelets (9) attached to the side tubes (1) are crossed by the lines (8) connecting the front and back. Les extrémités supérieures du cordage (6) sont fixées sur ces lignes (8). The upper ends of the rope (6) are fixed on these lines (8). Ainsi lorsque l'utilisateur, accroché au harnais, pousse ou tire le palonnier pour modifier la puissance du cerf-volant, il augmente l'amplitude de relâchement des lignes opposées. Thus, when the user, hooked in, pushes or pulls the joystick to change the power the kite, it increases the magnitude of relaxation of opposing lines.

Selon une variante non illustrée, un premier tube de diamètre inférieur peut être inséré dans un tube de plus gros diamètre afin d'obtenir un modèle de fabrication différent du palonnier. According to a variant not illustrated, a first smaller diameter tube can be inserted into a tube of larger diameter to obtain a different manufacturing model lifter.
