Description

Barre de contrôle pour aile de traction avec enrouleur intégré Control bar for traction wing with integrated reel
La présente invention concerne un système de barre de contrôle pour les ailes de traction. Les ailes de traction ou les cerf-volants sont généralement retenus par des fils contrôlés par des poignées, des barres ou des guidons. La méthode classique, pour mettre l'aile en vol, consiste à déployer l'aile et les fils au sol. Ensuite, on fait décoller l'aile par traction sur les fils, souvent l'opérateur se fait aider pour soulever l'aile afin de faciliter son envol. Ce système présente le grave inconvénient de nécessiter une surface disponible au sol sensiblement égale à la longueur des fils sur la largeur de l'aile, soit un ordre de grandeur d'environ 150M2.The present invention relates to a control bar system for traction wings. The traction wings or kites are generally retained by wires controlled by handles, bars or handlebars. The classic method, to put the wing in flight, is to deploy the wing and the wires on the ground. Then, we take off the wing by pulling on the wires, often the operator is helped to lift the wing to facilitate its flight. This system has the serious drawback of requiring an available area on the ground which is substantially equal to the length of the wires over the width of the wing, an order of magnitude of approximately 150M 2 .
Des systèmes de barre de contrôle comprenant deux tiges, l'une rectiligne l'autre arquée et réunies ensemble par leurs extrémités sont connues. Elles comportent un moulinet, sur lequel sont enroulés deux fils; situé entre les deux tiges, chaque fil apparent relie une extrémité desdites tiges qui présentent un anneau traversés par le fil, l'extrémité des fils étant reliée à la voile.Control bar systems comprising two rods, one straight the other arched and joined together by their ends are known. They include a reel, on which two wires are wound; located between the two rods, each apparent wire connects one end of said rods which have a ring through which the wire passes, the end of the wires being connected to the sail.
Un but de la présente invention est de proposer un système de barre de contrôle dans lequel, les fils qui se prolongent en dehors de la gorge du moulinet jusqu'aux extrémités des tiges, ne sont pas aisément accrochés lors de la navigation par l'utilisateur.An object of the present invention is to provide a control bar system in which the wires which extend outside the reel groove to the ends of the rods are not easily hooked during navigation by the user .
Ce but est atteint du fait que le système de barre de contrôle pour aile de traction, comprend : un boîtier présentant deux ouvertures opposées et comportant un arbre d'entraînement traversant ledit boîtier, sensiblement perpendiculaire à la ligne passant par les deux ouvertures ; des organes d'enroulement solidaires en rotation dudit arbre d'entraînement, susceptibles de recevoir au moins deux enroulements de fil, chaque fil étant apte à être entraîné en translation dans des directions sensiblement opposées à travers lesdites ouvertures ; et, deux éléments tubulaires prolongeant lesdites deux ouvertures dans deux directions opposées l'une de l'autre et se terminant chacun par une extrémité libre, lesdits fils étant susceptibles de traverser chacun un des éléments tubulaires pour déboucher à chacune desdites extrémités libres, par quoi les portions de fil, raccordées à ladite aile de traction sont susceptibles d'être allongées ou raccourcies simultanément d'une même valeur.This object is achieved by the fact that the control bar system for the traction wing comprises: a housing having two opposite openings and comprising a drive shaft passing through said housing, substantially perpendicular to the line passing through the two openings; winding members integral in rotation with said drive shaft, capable of receiving at least two windings of wire, each wire being capable of being driven in translation in substantially opposite directions through said openings; and, two tubular elements extending said two openings in two directions opposite from each other and each ending in a free end, said wires being capable of passing through each of one of the tubular elements to lead to each of said free ends, whereby the portions of wire, connected to said traction wing are may be lengthened or shortened simultaneously by the same amount.
Ainsi, une caractéristique du système de barre de contrôle réside dans le mode d'encastrement des organes d'enroulement dans un boîtier et des fils dans les éléments tubulaires qui prolongent le boîtier. De la sorte, les organes d'enroulement et les fils, dans leur portion située dans l'élément tubulaire, sont isolés de l'extérieur et ne risque pas d'être accrochés par l'utilisateur dont les deux mains enserrent les éléments tubulaires durant la navigation.Thus, a characteristic of the control bar system resides in the manner of embedding the winding members in a housing and of the wires in the tubular elements which extend the housing. In this way, the winding members and the wires, in their portion located in the tubular element, are isolated from the outside and do not risk being hooked by the user whose two hands grip the tubular elements during navigation.
En outre, ce nouveau système permet de décoller la voile avec des espaces réduits, il améliore considérablement la sécurité, la maniabilité, le confort et aussi la performance des voiles de traction. L'invention permet de décoller l'aile en ne débobinant que quelques mètres de fils. En soulevant la barre d'environ 1.5M du sol, la voile décolle. L'invention permet en outre de moduler la longueur des fils en fonction des besoins. Elle est donc particulièrement intéressante, car elle réduit la surface nécessaire à la mise en vol, facilite et sécurise cette phase délicate. Il devient ensuite possible de moduler la longueur des fils en fonction de l'espace disponible. La force du vent variant avec l'altitude, en modulant la longueur des fils on peut placer la voile, à une altitude voulue permettant ainsi de choisir une force de vent adaptée et un angle de fils adaptés à la puissance de traction recherchée.In addition, this new system makes it possible to take off the sail with reduced spaces, it considerably improves the safety, the handling, the comfort and also the performance of the traction sails. The invention makes it possible to take off the wing by unwinding only a few meters of son. By lifting the bar about 1.5M from the ground, the sail takes off. The invention also makes it possible to modulate the length of the wires as required. It is therefore particularly interesting, because it reduces the surface necessary for flight, facilitates and secures this delicate phase. It then becomes possible to adjust the length of the wires according to the space available. The force of the wind varying with the altitude, by modulating the length of the wires, the sail can be placed at a desired altitude, thus making it possible to choose a suitable wind force and an angle of wires adapted to the desired pulling power.
L'invention permet donc une économie de matériel à acheter et accroît la longévité de l'ensemble barre-voile-fils en permettant des largages plus faciles et plus rapides ; il en va de même pour le rangement. De façon préférentielle, ledit boîtier comprend des moyens de commande susceptibles d'entraîner en rotation ledit arbre d'entraînement. De la sorte, la voile es susceptible d'être éloignée ou rapprochée de l'utilisateur durant la navigation afin de profiter des conditions de vent optimales, c'est-à-dire en ajustant la voile dans la couche d'air appropriée, en fonction de la vitesse du vent. En outre, lors du pliage du système de barre, les fils sont aisément enroulés grâce auxdits moyens de commande.The invention therefore makes it possible to save material to purchase and increases the longevity of the bar-sail-son assembly by allowing easier and faster drops; the same goes for storage. Preferably, said housing comprises control means capable of driving said drive shaft in rotation. In this way, the sail is likely to be distant or brought closer to the user during navigation in order to take advantage of optimal wind conditions, that is to say by adjusting the sail in the appropriate layer of air, depending on the wind speed. In addition, during the folding of the bar system, the wires are easily wound up thanks to said control means.
Avantageusement, ledit arbre d'entraînement comprend des moyens de freinage et des moyens de commande desdits moyens de freinage, et lesdits moyens de freinage sont commandables entre une position de repos où ils bloquent ledit arbre d'entraînement et une position de travail où ils libèrent ledit arbre d'entraînement. Ainsi, lorsque l'opérateur est en position de navigation et que la voile est située à la bonne altitude, les portions de fil qui séparent le système de barre de contrôle de la voile sont maintenus à une longueur fixe par les moyens de freinage qui bloquent l'arbre d'entraînement dans leur position de repos. De la sorte, l'opérateur n'exerce aucun travail pour coincer les fils en position normale de navigation. En revanche, il actionne les moyens de commande des moyens de freinage pour libérer les fils et pour éloigner la voile du système de barre. De même, lors du raccourcissement des fils, l'opérateur libère le frein de façon à commander la rotation des organes d'enroulement.Advantageously, said drive shaft comprises braking means and means for controlling said braking means, and said braking means are controllable between a rest position where they block said drive shaft and a working position where they release said drive shaft. Thus, when the operator is in the navigation position and the sail is located at the correct altitude, the portions of wire which separate the control bar system from the sail are kept at a fixed length by the braking means which block the drive shaft in their rest position. In this way, the operator does no work to wedge the wires in the normal navigation position. On the other hand, it actuates the means for controlling the braking means to release the wires and to move the sail away from the helm system. Similarly, during the shortening of the wires, the operator releases the brake so as to control the rotation of the winding members.
Selon un mode particulier de mise en oeuvre de l'invention, lesdits moyens de freinage comprennent une bande flexible située dans le boîtier et maintenue à force autour dudit arbre par des moyens élastiques, lesdits moyens de commande étant aptes à compenser l'action desdits moyens élastiques pour libérer ladite bande flexible dudit arbre. Ainsi, une caractéristique desdits moyens de freinage réside dans l'application à force d'une bande flexible dans au moins une portion du pourtour de l'arbre d'entraînement de façon à induire des frottements susceptibles de le bloquer. La tension de cette bande flexible qui est adaptée à la force de traction des fils sur le système de barre et sur l'opérateur est réalisée par des moyens élastiques. Ces moyens élastiques sont libérables par lesdits moyens de commande desdits moyens de freinage.According to a particular embodiment of the invention, said braking means comprise a flexible band located in the housing and held by force around said shaft by elastic means, said control means being able to compensate for the action of said means elastic to release said flexible strip from said shaft. Thus, a characteristic of said braking means lies in the application by force of a flexible strip in at least a portion of the periphery of the drive shaft so as to induce friction liable to block it. The tension of this flexible strip which is adapted to the tensile force of the wires on the bar system and on the operator is produced by elastic means. These elastic means can be released by said control means of said braking means.
De façon particulièrement avantageuse, lesdits organes d'enroulement comprennent des bobines montées de façon coaxiale sur ledit arbre d'entraînement. De la sorte, les fils sont chacun enroulés sur une bobine et sont susceptibles d'être enroulés ou déroulés simultanément en actionnant l'arbre en rotation.In a particularly advantageous manner, said winding members comprise coils mounted coaxially on said drive shaft. In this way, the wires are each wound on a reel and are capable of being wound or unwound simultaneously by actuating the shaft in rotation.
Préférentiel lement, le système de barre de contrôle comporte un bout de harnais reliant entre eux les deux éléments tubulaires et une poulie posée sur ledit bout de harnais reliée à une pièce d'accrochage par un axe pivotant dans une chape. Ainsi, la position de l'opérateur par rapport au système de barre est aisément ajustable sans frottement considérable, comme cela est le cas lorsque le bout est directement relié au crochet du harnais. Selon un autre mode particulier de mise en œuvre de l'invention, le système de barre de contrôle comprend des moyens de frottement susceptibles d'être appliqués contre lesdits fils lors de l'enroulement de ceux-ci sur les organes d'enroulement de façon à tendre les fils. Ainsi, les fils sont enroulés sur chacune des bobines de manière serrée de façon à obtenir une longueur de fil maximale et identique dans chaque enroulement.Preferably, the control bar system comprises a harness end connecting the two tubular elements together and a pulley placed on said harness end connected to a hooking piece by a pivoting axis in a yoke. Thus, the position of the operator relative to the bar system is easily adjustable without considerable friction, as is the case when the end is directly connected to the hook of the harness. According to another particular embodiment of the invention, the control rod system comprises friction means capable of being applied against said wires during the winding of these on the winding members so to stretch the threads. Thus, the wires are wound on each of the coils in a tight manner so as to obtain a maximum and identical length of wire in each winding.
Avantageusement, le système de barre de contrôle comporte un système de protection dudit boîtier par une mousse évitant les blessures en cas de choc et permettant à l'ensemble de flotter. L'ensemble est très compact, et bien qu'il offre un risque moindre en cas de chocs, il pourra être facilement enveloppé d'une mousse de protection améliorant aussi la flottabilité.Advantageously, the control bar system includes a system for protecting said housing with a foam preventing injuries in the event of an impact and allowing the assembly to float. The assembly is very compact, and although it offers a lower risk in the event of impact, it can be easily wrapped in a protective foam also improving buoyancy.
Selon un troisième mode particulier de mise en œuvre de l'invention, lesdits organes d'enroulement comportent un troisième enroulement de fil et le boîtier présente en outre une troisième ouverture que ledit fil traverse pour être raccordé à ladite aile. Ainsi, le troisième fil qui est relié à l'aile de traction, permet de la maintenir dans une position fixe en rotation autour de l'axe passant par les deux points de fixation des deux autres fils sur l'aile.According to a third particular embodiment of the invention, said winding members comprise a third wire winding and the housing also has a third opening that said wire passes through to be connected to said wing. So the third thread which is connected to the traction wing, makes it possible to maintain it in a fixed position in rotation about the axis passing through the two fixing points of the two other wires on the wing.
Avantageusement, le système de barre de contrôle comprend en outre des moyens d'entraînement en translation dudit fil dudit troisième enroulement pour raccourcir ou allonger ledit fil par rapport aux autres fils. De la sorte, on peut faire varier la position de l'aile de traction autour de l'axe passant par les deux points de fixation des deux autres fils sur l'aile, ce qui permet d'orienter l'aile et de faire varier sa surface au vent. Selon un quatrième mode particulier de mise en œuvre de l'invention, lesdits organes d'enroulement comprennent quatre enroulements de fils, lesdits fils étant appariés deux à deux de façon qu'une paire de fils débouche à chacune des extrémités libres desdits organes tubulaires. Ainsi, selon ce mode de mise en œuvre, l'inclinaison de l'aile de traction est déterminée par longueur relative des deux portions de fils reliant chacune des extrémités libres des éléments tubulaires à la voile, ce qui en permet un meilleur contrôle.Advantageously, the control bar system further comprises means for driving in translation said wire of said third winding to shorten or lengthen said wire relative to the other wires. In this way, the position of the traction wing can be varied around the axis passing through the two fixing points of the two other wires on the wing, which makes it possible to orient the wing and to vary its surface in the wind. According to a fourth particular embodiment of the invention, said winding members comprise four windings of wires, said wires being paired in pairs so that a pair of wires opens out at each of the free ends of said tubular members. Thus, according to this embodiment, the inclination of the traction wing is determined by the relative length of the two portions of son connecting each of the free ends of the tubular elements to the sail, which allows better control.

L'invention consiste à intégrer sur la partie centrale de la barre (15) une ou plusieurs bobines (3) juxtaposées. Disposer la, ou les bobines à l'intérieur de la partie centrale, permet de passer les fils dans les poignées (1 A), (1 B) et (8).The invention consists in integrating on the central part of the bar (15) one or more coils (3) juxtaposed. Arrange the, or the coils inside the central part, allows to pass the wires in the handles (1 A), (1 B) and (8).
En référence à ces dessins, la barre est principalement constituée de deux éléments tubulaires ou tubes (1A) et (1 B) du type de ceux utilisés pour les wishbones de planche à voiles. La partie centrale (15), reliant ces deux tubes, est beaucoup plus volumineuse et permet d'y introduire la ou les bobines et éventuellement le frein (12). Cette partie centrale pourra être constituée du même matériau que les tubes (1A) et (1 B) comme l'aluminium, fibres de verre, de carbone, plastique moulé, contre-plaqué cintré ou moulé, ou tout autre matériau adapté. Elle (15) est assemblée sur (1A) et (1 B) par soudure, vissage, rivetage ou collage. Elle peut aussi être réalisée de façon monobloc avec les poignées (1A) et (1 B). Elle (15) permettra la dépose des bobines et du frein sans outillage spécial. A cet effet, la partie centrale (15) s'ouvrira sur un côté.With reference to these drawings, the bar is mainly made up of two tubular elements or tubes (1A) and (1B) of the type of those used for the windsurfing boom. The central part (15), connecting these two tubes, is much larger and allows the introduction of the coil (s) and possibly the brake (12). This central part may be made of the same material as the tubes (1A) and (1 B) such as aluminum, glass fibers, carbon, molded plastic, bent or molded plywood, or any other suitable material. It (15) is assembled on (1A) and (1 B) by welding, screwing, riveting or gluing. It can also be made in one piece with the handles (1A) and (1 B). Her (15) will allow the removal of the coils and the brake without special tools. For this purpose, the central part (15) will open on one side.
Le bobinage des fils s'effectue par la mise en rotation des bobines (3) à l'aide de la poignée (10). Les fils (2) et (21) passent à l'intérieur de la barre, (1), qui est généralement creuse.The winding of the wires is carried out by rotating the coils (3) using the handle (10). The wires (2) and (21) pass inside the bar, (1), which is generally hollow.
Des poulies (11) pourront limiter les frottements aux renvois d'angles situés dans ou sur la barre entre la bobine et la voile.Pulleys (11) can limit friction at the angle references located in or on the bar between the reel and the sail.
D'autre part le débobinage ne se fait que si l'opérateur actionne la commande (24) du frein (Figure 12). Une bande flexible 26 ou sangle présente une première extrémité reliée à un point fixe 25, lequel est situé à proximité d'une poulie, ou frein, solidaire en rotation de l'arbre 13. La bande flexible 26 est maintenue contre la poulie 12 dans une partie substantielle de sa circonférence par des moyens élastiques 23 de façon à en assurer le blocage. L'actionnement de la commande 24 compense l'action des moyens élastiques et libère la bande flexible de la poulie 12.On the other hand, the unwinding is only done if the operator actuates the brake control (24) (Figure 12). A flexible band 26 or strap has a first end connected to a fixed point 25, which is located near a pulley, or brake, integral in rotation with the shaft 13. The flexible band 26 is held against the pulley 12 in a substantial part of its circumference by elastic means 23 so as to block it. The actuation of the control 24 compensates for the action of the elastic means and releases the flexible strip from the pulley 12.
Le frein (12) est solidaire en rotation avec la ou les bobines (3) et le bras (9) par l'arbre (13). Il développera un couple suffisamment important pour pouvoir s'opposer au débobinage même pendant les tractions les plus fortes. Il permet en outre de contrôler la vitesse d'eloignement de la voile en disposant d'une commande actionnant le dosage du couple produit par le frein. Il peut être totalement neutralisé, pendant le rembobinage des fils notamment. Il peut être du type à sangle (26) (Figure12), (plate ou trapézoïdale), à patins, tambour, disque. Il doit aussi permettre de s'opposer au débobinage par les vents les plus forts, et permettre le dosage du couple produit sur le système d'enroulage des fils pendant le débobinage en actionnant la commande (24). La commande (24) a son point fixe en extrémité de (1 A) ou (1 B) ou sur (8).The brake (12) is integral in rotation with the coil (s) (3) and the arm (9) by the shaft (13). It will develop a torque large enough to be able to oppose the unwinding even during the strongest pulls. It also makes it possible to control the speed at which the sail is moving away by having a control actuating the dosage of the torque produced by the brake. It can be completely neutralized, especially during the rewinding of the wires. It can be of the strap type (26) (Figure 12), (flat or trapezoidal), with pads, drum, disc. It must also make it possible to oppose unwinding by the strongest winds, and allow the metering of the torque produced on the wire winding system during unwinding by actuating the control (24). The control (24) has its fixed point at the end of (1 A) or (1 B) or on (8).
L'invention n'est pas liée au nombre de fils. Ils sont le plus souvent au nombre de deux (Figures 1 , 2 et 3 ), trois (Figures 7, 8, 9 et 10 ) ou quatre (Figures 4, 5 et 6 ). Les groupes de fils, en nombres pairs, reliant la voile à la barre, quitteront avantageusement la bobine dans des points diamétralement opposés. (Fig 2 et 5).The invention is not related to the number of wires. They are most often two in number (Figures 1, 2 and 3), three (Figures 7, 8, 9 and 10) or four (Figures 4, 5 and 6). The groups of children, in even numbers, connecting the sail to the bar, advantageously leave the reel in diametrically opposite points. (Fig 2 and 5).
Les groupes de fils en nombres impairs auront la même disposition sauf pour le fil central qui arrivera sur la bobine centrale. (Figures 7, 8, 9 et 10 ). Après le passage du fil (21 ) sur les renvois d'angle centraux (11 ), il pourra être ajusté en longueur (Figures 8 et 10 ) en actionnant un bout (31 ) agissant sur une poulie (32) ou un anneau coulissant, et éventuellement, maintenu par un taquet coinceur pour s'adapter aux conditions de navigation ou affaler la voile. La poulie (32) agira sur le fil (21 ) transversalement entre les poulies (11 ) et la bobine (3) de façon à raccourcir la portion de fil 21 qui sépare le système de barre du point de fixation du fil 21 sur la voile.The groups of wires in odd numbers will have the same arrangement except for the central wire which will arrive on the central coil. (Figures 7, 8, 9 and 10). After the passage of the wire (21) on the central corner gears (11), it can be adjusted in length (Figures 8 and 10) by actuating a tip (31) acting on a pulley (32) or a sliding ring, and possibly maintained by a cleat cleat to adapt to sailing conditions or to lower the sail. The pulley (32) will act on the wire (21) transversely between the pulleys (11) and the spool (3) so as to shorten the portion of wire 21 which separates the bar system from the point of attachment of the wire 21 to the sail .
L'enroulage des fils sur la bobine sera avantageusement effectué manuellement à l'aide d'une poignée (10) (Figures 1 , 3, 4, 6, 7 et 9 ) posée sur un bras (9) entraînant l'arbre de la bobine (13). Par basculement de ce bras (9), (articulé au point de liaison avec l'arbre porte bobine 13), on amène la poignée de manœuvre contre la partie centrale de la barre (position Z). La poignée se trouve ainsi, en partie, escamotée et apporte un blocage supplémentaire au débobinage. Un ressort situé dans le bras le maintiendra dans l'une des trois positions suivantes : bobinage en position X (poignée vers le haut), centrale en position Y (axe bras sensiblement dans l'axe de la bobine), et blocage en position Z (poignée butant contre la barre). D'une manière générale ce ressort agira sur le bout d'arbre de la bobine. Un leash (16) (Figures 1 , 4 et 7) de sécurité reliant l'extrémité de l'une des poignées (1A), (1 B) ou (8) à l'utilisateur permettra de retenir la barre même si elle échappait à l'utilisateur et déséquilibrera la voile afin de l'affaler. Un bout de harnais (17) (Figures 1 ,4, 7 et 11 ) relie la barre à l'opérateur, généralement équipé d'un harnais, ou au mobile à déplacer, pour soulager les efforts de l'utilisateur. Dans le cas d'une voile trois fils, le leash (16) pourra être supprimé et remplacé par le bout (31 ). Un système plaça entre la barre et l'objet à tracter (harnais de l'opérateur ou partie du mobile) permettra par pivotement de compenser la rotation entre la voile et l'objet tracté.The winding of the wires on the spool will advantageously be carried out manually using a handle (10) (Figures 1, 3, 4, 6, 7 and 9) placed on an arm (9) driving the shaft of the coil (13). By tilting this arm (9) (articulated at the point of connection with the reel-carrying shaft 13), the operating handle is brought against the central part of the bar (position Z). The handle is thus, in part, retracted and provides additional blocking when unwinding. A spring located in the arm will hold it in one of the following three positions: winding in position X (handle up), central in position Y (arm axis substantially in the axis of the coil), and locking in position Z (handle abutting against the bar). In general, this spring will act on the end of the reel shaft. A safety leash (16) (Figures 1, 4 and 7) connecting the end of one of the handles (1A), (1 B) or (8) to the user will allow the bar to be retained even if it escapes to the user and unbalance the sail in order to lower it. A harness end (17) (Figures 1, 4, 7 and 11) connects the bar to the operator, generally equipped with a harness, or to the mobile to be moved, to relieve the efforts of the user. In the case of a three-wire sail, the leash (16) can be removed and replaced by the end (31). A system placed between the bar and the object to be towed (operator's harness or part of the mobile) will allow by pivoting to compensate for the rotation between the sail and the towed object.
En référence à la figure (11 ) ce système pourra être composé d'un anneau ou d'une poulie (18) placé sur le bout (17). Cette poulie (18) est reliée à un anneau (20) par une chape (27) et un axe pivotant (19). Ceci permet une rotation facile entre la barre (1 ) et la liaison avec l'anneau (20) ou un bout ou autre moyen relié au harnais de l'opérateur ou au mobile. Ce système permettra de compenser le vrillage des fils consécutif à une rotation de la voile ou de l'opérateur sans interrompre la liaison par le bout de harnais, en effectuant une simple rotation de la barre.Referring to Figure (11) this system may be composed of a ring or a pulley (18) placed on the end (17). This pulley (18) is connected to a ring (20) by a yoke (27) and a pivoting axis (19). This allows easy rotation between the bar (1) and the connection with the ring (20) or a tip or other means connected to the operator's harness or to the mobile. This system will compensate for the twisting of the wires following a rotation of the sail or of the operator without interrupting the connection by the end of the harness, by simply rotating the bar.
Plus précisément la figure (12) illustre le système de freinage : Le frein pourra être un frein à disque de V.T.T., à tambour ou, de façon préférée, à sangle (26). La sangle (26) est actionnée par une traction élastique(23) (ressort, caoutchouc), elle est libérée par un bout (24) lié à un point fixe, barre (1A) ou (1 B) ou poignée (8). Cette extrémité peut être équipée d'un taquet coinceur pour le réglage en longueur ou d'un réglage par vis écrou. La sangle peut aussi être libérée par une commande de frein de vélo. Le sens de rotation indiqué par la flèche (30) (Figure 12) est celui du débobinage. Ce sens de rotation est lié au sens d'enroulement de la courroie qui doit être auto serrante pour s'opposer au débobinage. Toutefois lorsqu'on libère le frein en actionnant la commande (24) le débobinage doit s'effectuer facilement. De bons résultats ont étés obtenus avec des poulies et courroies standards du type de celles utilisées pour entraîner les ventilateurs utilisés en automobile. Une extrémité de la courroie et assemblée à un point fixe (25) l'autre est tirée par le ressort (23).More specifically, figure (12) illustrates the braking system: The brake could be a V.T.T. disc brake, drum or, preferably, strap (26). The strap (26) is actuated by an elastic traction (23) (spring, rubber), it is released by an end (24) linked to a fixed point, bar (1A) or (1 B) or handle (8). This end can be fitted with a cleat cleat for length adjustment or adjustment with a screw nut. The strap can also be released by a bicycle brake control. The direction of rotation indicated by the arrow (30) (Figure 12) is that of the unwinding. This direction of rotation is linked to the direction of winding of the belt which must be self-tightening to oppose unwinding. However when the brake is released by actuating the control (24) the unwinding must be carried out easily. Good results have been obtained with standard pulleys and belts of the type used to drive the fans used in cars. One end of the belt and assembled at a fixed point (25) the other is pulled by the spring (23).
Les poignées (8) incluront un dispositif pour être réglables en longueur ou coulisser par rapport à la liaison (14) de façon à s'adapter à l'équilibre de chaque voile. Elles pourront aussi s'inspirer des systèmes « vario » des wishbones en utilisant des tubes coaxiaux coulissant l'un dans l'autre et d'un système de blocage après réglage. On pourra les équiper de mousse pour améliorer la préhension et l'ergonomie.The handles (8) will include a device to be adjustable in length or slide relative to the link (14) so as to adapt to the balance of each sail. They can also be inspired by systems “Vario” of the wishbones using coaxial tubes sliding one inside the other and a locking system after adjustment. We can equip them with foam to improve grip and ergonomics.
L'assemblage tournant (14) est principalement composé d'un tube, assemblé à une extrémité sur la poignée (8). Il est coaxial avec (1A) ou (1 B). Ce tube lui est d'un diamètre juste inférieur ou supérieur. Il est bloqué en translation par un clip pour être démontable. Le clip est placé dans le trou rond percé dans l'un des tubes et dans une rainure oblongue perpendiculairement à l'axe de l'autre tube. Ce dispositif permet de limiter la rotation des poignées (8) l'une par rapport à l'autre et par rapport à la barre (1 ). Il évite ainsi le vrillage des fils qui serait provoqué par la rotation complète d'une poignée.The rotary assembly (14) is mainly composed of a tube, assembled at one end on the handle (8). It is coaxial with (1A) or (1 B). This tube is just smaller or larger in diameter. It is blocked in translation by a clip to be removable. The clip is placed in the round hole drilled in one of the tubes and in an oblong groove perpendicular to the axis of the other tube. This device makes it possible to limit the rotation of the handles (8) relative to one another and relative to the bar (1). It thus avoids the twisting of the wires which would be caused by the complete rotation of a handle.
La figure (13) représente le détail (F) du passage des fils dans l'extrémité des poignées (1A) et (1 B) dans le cas des barres à deux et trois fils pour les barres quatre fils les mêmes dispositions sont prises dans les extrémités des poignées (8). Il s'agit du système de freinage des fils permettant d'avoir toujours une tension suffisante des fils pour un bobinage bien serré. Un ressort à lame (28) pousse le fil (2) sur une surface résistante au frottement (29) entre les poulies (11 ). Lors du débobinage, par la force de traction du fil le ressort fléchit, et n'applique plus le fil contre la surface frottante.Figure (13) shows the detail (F) of the passage of the wires in the end of the handles (1A) and (1 B) in the case of two and three wire bars for the four wire bars the same arrangements are made in the ends of the handles (8). This is the wire braking system which always provides sufficient wire tension for a tight winding. A leaf spring (28) pushes the wire (2) onto a friction-resistant surface (29) between the pulleys (11). During the unwinding, by the tensile force of the wire, the spring flexes, and no longer applies the wire against the rubbing surface.
Une mousse enveloppant la partie centrale protégera des blessures en cas de choc, et permettra à l'ensemble de flotter. Cette mousse sera élastique et non absorbante à l'eau. Elle sera fixée sur la barre tout en permettant le démontage des bobines et du frein. La partie recouvrant le bras (9), et la poignée (10) pourra se découvrir facilement pendant la navigation de façon à ne pas gêner la rotation du bras (9). Elle pourra également se recouvrir facilement après les opérations de débobinage ou de rembobinage. Une fixation du type « velcro » permettra de maintenir la partie ouvrante en position fermée et ouverte dans de bonnes conditions de facilité, de rapidité et de sécurité. On se référera maintenant à la Figure 14 pour décrire un mode de réalisation particulier du système de barre conforme à l'invention comportant trois fils. On retrouve sur la Figure 14 les deux fils 2 qui traversent les éléments tubulaire 1A et 1B prolongeant le boîtier de chaque côté. Les deux fils sont enroulés sur les bobines 13 puis sont guidées par deux galets 11 avant d'entrer dans les éléments tubulaires 1 A et 1 B afin de ne pas être directement en contact avec l'angle du boîtier et des éléments tubulaires de façon à ne pas provoquer une usure prématurée des fils. En outre, le bout 31 présente une extrémité susceptible d'agir directement sur le troisième fil 21 au-delà des poulies 11 et non entre ces dernières et les organes d'enroulements 3. Ainsi, en exerçant une traction sur le bout 31 , on raccourcit le troisième fil 21 , ce qui permet d'orienter la voile lors de la navigation. La Figure 15 illustre un système de barre de contrôle, dans lequel les bobines 3 et les moyens de freinage sont intégrés dans la partie centrale 15 ou boîtier, les fils 2 traversant les éléments tubulaire 1A et 1 B. Ainsi, les fils 2 ne débouchent à l'extérieur du système de barre qu'à l'extrémité libre des éléments tubulaires. En outre, les portions de fil 2 située entre le bord des bobines 3 et l'extrémité libre des éléments tubulaires coulissent dans des gaines 40 de façon à éviter l'usure des fils. De plus, les gaines 40, généralement en matière plastique constituent des moyens de frottement permettant la tension des fils 2 lors de leur enroulage. Foam enveloping the central part will protect from injuries in the event of an impact, and will allow the whole to float. This foam will be elastic and not absorbent in water. It will be fixed on the bar while allowing the disassembly of the coils and the brake. The part covering the arm (9), and the handle (10) can be easily discovered during navigation so as not to hinder the rotation of the arm (9). It can also be easily covered after the unwinding or rewinding operations. A "velcro" type fastening will keep the opening part in the closed and open position in good conditions of ease, speed and security. Reference will now be made to FIG. 14 to describe a particular embodiment of the bar system according to the invention comprising three wires. Found in Figure 14 the two son 2 which pass through the tubular elements 1A and 1B extending the housing on each side. The two wires are wound on the coils 13 then are guided by two rollers 11 before entering the tubular elements 1 A and 1 B so as not to be in direct contact with the angle of the housing and the tubular elements so as to do not cause premature wear of the wires. In addition, the end 31 has an end capable of acting directly on the third wire 21 beyond the pulleys 11 and not between the latter and the winding members 3. Thus, by exerting traction on the end 31, we shortens the third wire 21, which makes it possible to orient the sail during navigation. Figure 15 illustrates a control bar system, in which the coils 3 and the braking means are integrated in the central part 15 or housing, the wires 2 passing through the tubular elements 1A and 1 B. Thus, the wires 2 do not open out outside the bar system at the free end of the tubular elements. In addition, the wire portions 2 located between the edge of the coils 3 and the free end of the tubular elements slide in sheaths 40 so as to avoid wear of the wires. In addition, the sheaths 40, generally made of plastic, constitute friction means allowing the tension of the wires 2 during their winding.
