Description

Harnais rotatif pour la pratique d'un sport aérotracté Rotary harness for practicing a jet sport
La présente invention concerne un dispositif pour la pratique d'un sport aérotracté tel que le kitesurf, qui permet à un utilisateur d'effectuer une rotation complète sur lui-même sans devoir se décrocher d'un cerf volant auquel il est relié par un ensemble de câbles.The present invention relates to a device for the practice of an aerotracted sport such as kitesurfing, which allows a user to perform a complete rotation on itself without having to unhook a kite to which it is connected by a set of cables.
ARRIERE PLAN DE L'INVENTIONBACKGROUND OF THE INVENTION
Pour la pratique du kitesurf, l'utilisateur porte à ses pieds une planche lui permettant de glisser sur l'eau, et il est relié par un ensemble de câbles à un cerf volant, pour glisser sur l'eau en étant tracté par ce cerf volant.For the practice of kitesurfing, the user has at his feet a board allowing him to slide on the water, and he is connected by a set of cables to a kite, to slide on the water being towed by this deer wheel.
Dans ce cadre, l'utilisateur est équipé d'un dispositif comportant un harnais en matière textile et un moyen d'attache fixé à ce harnais, ce moyen d'attache étant solidarisé à une extrémité d'un câble principal dont l'autre extrémité est reliée au cerf volant.In this context, the user is equipped with a device comprising a harness made of textile material and a fastening means attached to this harness, this attachment means being secured to one end of a main cable whose other end is connected to the kite.
Complémentairement, deux autres câbles relient l'utilisateur au cerf volant, l'utilisateur manoeuvrant les extrémités de ces autres câbles avec ses bras, via une barre de direction, pour orienter et diriger le cerf volant, et plus généralement pour moduler la puissance de traction délivrée par ce cerf volant.Complementarily, two other cables connect the user to the kite, the user manipulating the ends of these other cables with his arms, via a steering bar, to orient and direct the kite, and more generally to modulate the traction power delivered by this kite.
L'utilisateur peut ainsi glisser sur l'eau, et s'envoler pour effectuer, au dessus de l'eau, une figure libre telle qu'une rotation. Avec un dispositif traditionnel, la réalisation de cette rotation nécessite de décrocher le câble principal du harnais, pivoter d'un tour complet, et accrocher à nouveau le câble principal au harnais.The user can thus slide on the water, and fly to perform, above the water, a free figure such as a rotation. With a traditional device, the realization of this rotation requires unhooking the main cable of the harness, rotate a full turn, and hang the main cable to the harness.
Cette opération est très physique parce qu'une fois le cerf volant décroché, l'utilisateur doit le retenir uniquement par la force de ses bras, et elle est technique du fait que dans cette situation, l'utilisateur ne peut pas manœuvrer le cerf volant pour moduler la puissance de traction.This operation is very physical because once the kite is off the hook, the user must hold it only by the force of his arms, and it is technical because in this situation, the user can not maneuver the kite. to modulate the pulling power.
Il est connu du document FR2856307'un dispositif comportant un harnais et une ceinture solidarisée à ce harnais et entourant l'utilisateur, cette ceinture ayant une forme de bande circulaire.It is known from FR2856307 ' a device comprising a harness and a belt secured to this harness and surrounding the user, this belt having a circular band shape.
Un chariot roule le long de cette bande, et porte le moyen d'attache auquel est accroché le câble principal du cerf volant. Avec ce dispositif, l'utilisateur peut effectuer une rotation complète sans devoir se décrocher. En pratique, il est relativement long d'acquérir ia maîtrise d'un tel dispositif, de sorte qu'ii est finalement peu utilisé.A carriage rolls along this band, and carries the attachment means which is attached to the main cable of the kite. With this device, the user can perform a complete rotation without having to unhook. In practice, it is relatively slow to acquire the control of such a device, so that it is finally little used.

DESCRIPTION DETAILLEE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION
Le dispositif selon l'invention comprend un harnais textile et un rail fermé destiné à entourer un utilisateur au niveau de sa ceinture, ainsi qu'un chariot portant une boucle crochet, ce chariot circulant le long du rail.The device according to the invention comprises a textile harness and a closed rail for surrounding a user at its belt, and a carriage carrying a hook loop, the carriage running along the rail.
Le harnais comporte plusieurs sangles ajustables engagées dans des boucles correspondantes du rail, de façon à solidariser fermement le rail à l'utilisateur, au niveau de sa ceinture, pour permettre à la boucle crochet portée par le chariot de circuler librement le long du rail, tout autour de l'utilisateur.The harness has several adjustable straps engaged in corresponding loops of the rail, so as to securely fasten the rail to the user, at its belt, to allow the hook loop carried by the carriage to move freely along the rail, all around the user.
Dans un premier mode de réalisation de l'invention qui est représenté aux figures 1 à 3, le rail repéré par 1 est fabriqué dans un profilé présentant une section transversale en C. Il a une forme générale fermée circulaire autour d'un axe de révolution AX1 représenté en figure 1, cette forme pouvant aussi être ovoïde ou analogue, et il reçoit un chariot repéré par 2 portant une boucle crochet 3.In a first embodiment of the invention which is represented in FIGS. 1 to 3, the rail marked with 1 is manufactured in a profile having a cross-section in C. It has a generally closed circular shape around an axis of revolution. AX1 shown in Figure 1, this shape can also be ovoid or the like, and it receives a carriage marked by 2 carrying a hook loop 3.
Comme visible en figure 2, deux trous 4, 6 sont réalisés en partie avant de ce rail 1 , en étant alignés selon un axe AX2 normal au plan général du rail 1 , pour recevoir une goupille 7. Cette goupille 7 permet d'immobiliser le chariot 2 à une position située au centre de la partie avant du rail, lorsqu'elle est engagée conjointement dans les trous 4 et 6 et dans un trou central 8 du chariot 2.As can be seen in FIG. 2, two holes 4, 6 are made in the front part of this rail 1, being aligned along an axis AX2 normal to the general plane of the rail 1, to receive a pin 7. This pin 7 makes it possible to immobilize the carriage 2 at a position located in the center of the front part of the rail, when it is engaged jointly in the holes 4 and 6 and in a central hole 8 of the carriage 2.
Sur la face intérieure du rail 1 se trouve une boucle 9 s'étendant parallèlement au plan du rail, ainsi que deux boucles 11 et 12 s'étendant perpendiculairement au plan du rail 1 , et une ouverture intérieure 13. La boucle 9 permet d'accrocher le rail 1 à une poignée arrière du harnais, les deux boucles 11 et 12 sont prises par deux sangles principales du harnais.On the inner face of the rail 1 is a loop 9 extending parallel to the plane of the rail, as well as two loops 11 and 12 extending perpendicularly to the plane of the rail 1, and an inner opening 13. The loop 9 allows hanging the rail 1 to a rear handle of the harness, the two loops 11 and 12 are taken by two main straps of the harness.
L'ouverture 13 permet d'introduire le chariot 2 à l'intérieur du profilé en C qui constitue le rail 1 , elle a à cet effet des dimensions supérieures à celles du chariot 2. Une plaque 14 maintient cette ouverture 13 fermée, en étant fixée au corps du rail 1 par quatre vis repérées par 16 traversant cette plaque pour se visser dans quatre pattes correspondantes 17 du rail 1.The opening 13 makes it possible to introduce the carriage 2 inside the C-profile which constitutes the rail 1, it has for this purpose dimensions greater than those of the carriage 2. A plate 14 maintains this opening 13 closed, being attached to the body of the rail 1 by four screws marked by 16 through this plate to screw into four corresponding legs 17 of the rail 1.
Le chariot 2 comprend une plaque principale 18 percée de trois trous incluant le trou central 8 destiné à recevoir la goupille 7, et deux trous latéraux non visibles dans les figures qui sont prévus pour recevoir deux axes repérés par 19 et 21. Les deux trous latéraux ont des diamètres supérieurs à ceux des axes 19 et 21 pour que ces axes puissent pivoter dans ces trous.The carriage 2 comprises a main plate 18 pierced with three holes including the central hole 8 intended to receive the pin 7, and two lateral holes not visible in the figures which are provided to receive two pins marked by 19 and 21. The two lateral holes have diameters greater than those of the axes 19 and 21 so that these axes can rotate in these holes.
Chacune des extrémités de chaque axe 19, 21 est emboîtée dans un roulement à billes, l'axe 19 portant ainsi les roulements 22 et 23, l'axe 21 portant quant à lui les roulements 24 et 25.Each of the ends of each axis 19, 21 is nested in a ball bearing, the shaft 19 thus bearing the bearings 22 and 23, the axis 21 carrying the bearings 24 and 25.
L'une des tranches de la plaque 18 constituant le corps du chariot 2 dépasse de la face périphérique externe du rial 1, deux tiges filetées 27 et 28 étant soudées à cette tranche de la plaque, pour recevoir la boucle crochet 3 qui se fixe à ces tiges filetées 27 et 28 grâce à quatre écrous repérés par 29.One of the slices of the plate 18 constituting the body of the carriage 2 protrudes from the outer peripheral face of the rial 1, two threaded rods 27 and 28 being welded to this slice of the plate, to receive the hook loop 3 which is fixed to these threaded rods 27 and 28 with four nuts marked 29.
Cette boucle crochet 3 peut par exemple être formée à partir d'une tige ou barre rectiligne qui est d'abord repliée en son centre, en ramenant ses extrémités parallèlement l'une à l'autre de manière à constituer une boucle. L'extrémité de cette boucle est ensuite rabattue sur elle-même pour lui donner une forme de crochet en vue de profil.This hook loop 3 may for example be formed from a rod or straight bar which is first folded in its center, bringing its ends parallel to each other so as to form a loop. The end of this loop is then folded back on itself to give it a hook shape in profile.
Le corps 31 de la boucle crochet constitué par cette tige recourbée est ensuite fixé à une embase 32 allongée, par exemple de façon rigide en soudant les extrémités libres de cette tige aux extrémités d'une face de cette embase. Cette embase comporte en outre deux trous 33 et 34 permettant de l'engager sur les tiges filetées du chariot afin de l'y fixer.The body 31 of the hook loop formed by this curved rod is then fixed to an elongated base 32, for example rigidly by welding the free ends of this rod to the ends of a face of this base. This base further comprises two holes 33 and 34 for engaging on the threaded rods of the carriage to fix it.
Le corps de boucle 31 peut aussi être monté rotatif par rapport à l'embase 34, de manière à permettre à ce corps de boucle de pivoter autour d'un àxe tangent au rail, lorsque le câble principal du cerf volant est incliné par rapport au plan du rail.The loop body 31 may also be rotatably mounted relative to the base 34, so as to allow this loop body to pivot about an axis tangent to the rail, when the main cable of the kite is inclined relative to the rail plane.
En fonctionnement, lorsque le cerf volant exerce une traction sur la boucle crochet 3, seuls les quatre roulements à billes 22 à 25 sont en contact avec le rail, au niveau de deux faces d'appui ou bandes de roulement formées par deux faces intérieures du rail 1.In operation, when the kite exerts traction on the hook loop 3, only the four ball bearings 22 to 25 are in contact with the rail, at two bearing faces or treads formed by two inner faces of the rail 1.
Comme indiqué plus haut, ce rail présente une section en C comportant en section, deux portions rectangulaires 35 et 36 orientées parallèlement à l'axe AX1, situées dans le prolongement l'une de l'autre, et séparées l'une de l'autre par une fente dans laquelle s'engage la plaque 18 du chariot 2.As indicated above, this rail has a section C comprising in section, two rectangular portions 35 and 36 oriented parallel to the axis AX1, located in the extension of one another, and separated one of the other by a slot in which engages the plate 18 of the carriage 2.
Ces deux portions 35 "et 36 dont les faces internes 37 et 38 constituent les faces d'appui ou bandes de roulement pour des roulements à billes du chariot, ont leurs extrémités opposées prolongées par deux portions rectangulaires 39 et 40 orientées radialement par rapport à l'axe AX1 , c'est à dire s'étendant perpendiculairement aux portions 35 et 36. Ces deux portions radiales ont leurs autres extrémités réunies par une portion 30 parallèle à l'axe AX1 , et constituant le fond du rail.These two portions 35 "and 36 whose inner faces 37 and 38 constitute the bearing faces or treads for ball bearings of the carriage, have their opposite ends extended by two rectangular portions 39 and 40 oriented radially relative to the AX1 axis, ie extending perpendicular to the portions 35 and 36. These two radial portions have their other ends joined by a portion 30 parallel to the axis AX1, and constituting the bottom of the rail.
Selon un second mode de réalisation qui est représenté dans les figures 4 à 8, le rail qui est repéré par 41 a aussi une forme générale circulaire autour d'un axe de révolution repéré par AX4, mais son corps a une section dont au moins une partie a la forme de la lettre T. Le chariot, qui est repéré par 42 dans les figures, comporte un corps ayant une section en U et portant une boucle crochet 43, ce corps étant apte à entourer une partie de la section en T du rail.According to a second embodiment which is represented in FIGS. 4 to 8, the rail which is marked by 41 also has a generally circular shape around an axis AX4, but its body has a section of which at least a portion has the shape of the letter T. The carriage, which is indicated by 42 in the figures, comprises a body having a U-shaped section and carrying a hook loop. 43, this body being able to surround part of the T-section of the rail.
Comme visible en figure 4, le rail 41 comporte deux boucles 44 et 46 perpendiculaires au plan de ce rail, et deux boucles 47 et 48 parallèles au plan de ce rail. Ces quatre boucles sont espacées les unes des autres d'environ quatre-vingt dix degrés autour de l'axe AX4 en étant par exemple soudées à une face interne du corps de rail.As visible in FIG. 4, the rail 41 has two loops 44 and 46 perpendicular to the plane of this rail, and two loops 47 and 48 parallel to the plane of this rail. These four loops are spaced from each other by about ninety degrees around the axis AX4 being for example welded to an inner face of the rail body.
Les deux boucles perpendiculaires qui sont espacées de quatre-vingt dix degrés l'une de l'autre constituent les boudes avant et elles sont prises dans deux sangles principales du harnais. Les deux autres boucles qui sont les boucles arrières sont prises dans des anneaux arrières du harnais.The two perpendicular loops, which are ninety degrees apart, constitute the front slats and are taken in two main harness straps. The other two loops that are the back loops are taken in back rings of the harness.
Le chariot 42 qui est engagé sur ce rail 41 comporte un corps 49 formé à partir d'une plaque généralement rectangulaire repliée pour avoir une section en U, définissant ainsi une portion principale 51 et deux portions latérales 52 et 53, chacune de ces portions ayant une forme de paroi rectangulaire. Le chariot 42 comporte également quatre galets, roulettes ou roulements à billes repérés par 54 à 57.The carriage 42 which is engaged on this rail 41 comprises a body 49 formed from a generally rectangular plate folded to have a U-shaped section, thus defining a main portion 51 and two lateral portions 52 and 53, each of these portions having a rectangular wall shape. The carriage 42 also comprises four rollers, rollers or ball bearings marked 54 to 57.
La première portion latérale 52 porte deux galets 54 et 55 qui sont situés au niveau de sa face interne, et la seconde portion latérale 53 porte les deux autres galets 56 et 57 qui sont aussi situés au niveau de sa face interne. Chacun des galets 54 à 57 est engagé sur une extrémité d'un axe dont l'autre extrémité est engagée dans un trou de la portion latérale correspondante, les axes et trous étant repérés respectivement par 58 à 61 et par 62 à 65.The first lateral portion 52 carries two rollers 54 and 55 which are located at its inner face, and the second lateral portion 53 carries the two other rollers 56 and 57 which are also located at its inner face. Each of the rollers 54 to 57 is engaged on one end of an axis whose other end is engaged in a hole of the corresponding lateral portion, the axes and holes being marked respectively by 58 to 61 and 62 to 65.
Les extrémités des axes 58 à 61 sont par exemple serties sur les portions latérales après avoir été engagées dans les trous de ces parois. Une fois l'ensemble monté, les galets 54 et 56 sont situés en vis-à-vis l'un de l'autre, les galets 55 et 57 sont aussi situés en vis-à-vis l'un de l'autre.The ends of the axes 58 to 61 are for example crimped on the lateral portions after being engaged in the holes of these walls. Once assembled, the rollers 54 and 56 are located vis-à-vis one another, the rollers 55 and 57 are also located vis-à-vis one another.
Lorsque le chariot 42 est engagé sur le rail 41 , comme dans la figure 4, les deux galets 54 et 55 roulent sur une première face d'appui ou bande de roulement de ce rail, repérée par 67, et les deux galets 56 et 57 roulent sur une seconde face d'appui ou bande de roulement de ce rail, repérée par 68. La première et la seconde face de roulement sont des faces internes cylindriques du rail 41. Comme indiqué plus haut, le rail 41 présente une section en T, comportant une portion rectangulaire 50, orientée radialement par rapport à l'axe AX4 et correspondant à la barre verticale de la lettre T. L'une des extrémités de cette portion 50 est prolongée par deux portions rectangulaires, 60 et 70 qui s'étendent perpendiculairement à la portion 50. Ces deux portions 60 et 70 sont situées dans le prolongement l'une de l'autre, parallèlement à l'axe AX4, et correspondent à la barre horizontale de la lettre T.When the carriage 42 is engaged on the rail 41, as in FIG. 4, the two rollers 54 and 55 roll on a first bearing face or tread of this rail, identified by 67, and the two rollers 56 and 57 roll on a second bearing surface or tread of this rail, identified by 68. The first and second bearing surface are cylindrical inner faces of the rail 41. As indicated above, the rail 41 has a T-shaped section, comprising a rectangular portion 50, oriented radially with respect to the axis AX4 and corresponding to the vertical bar of the letter T. One end of this portion 50 is extended by two rectangular portions, 60 and 70 which extend perpendicular to the portion 50. These two portions 60 and 70 are located in the extension of one another, parallel to the axis AX4, and correspond to the bar horizontal letter T.
La portion 50 constitue une âme rigidifiant le rail, et les portions 60 et 70 délimitent deux faces internes d'appui du chariot, ou bandes de roulement 67 et 68 qui sont séparées l'une de l'autre par l'âme 50. Lorsque le chariot est monté sur le rail, les roulements 56 et 57 sont en appui sur la bande de roulement 67 et les roulements 54 et 55 sont en appui sur la bande de roulement 68.The portion 50 constitutes a core stiffening the rail, and the portions 60 and 70 delimit two internal bearing faces of the carriage, or treads 67 and 68 which are separated from each other by the core 50. When the carriage is mounted on the rail, the bearings 56 and 57 are supported on the tread 67 and the bearings 54 and 55 bear against the tread 68.
Le chariot est d'autre part équipé d'une goupille 69 portée par sa portion principale 51. Cette goupille 69 est apte à s'engager dans un trou correspondant repéré par 71 , traversant une face externe 72 du rail 41 et orienté selon un axe AX5 radial par rapport à l'axe AX4.The carriage is further equipped with a pin 69 carried by its main portion 51. This pin 69 is able to engage in a corresponding hole marked 71, passing through an outer face 72 of the rail 41 and oriented along an axis AX5 radial with respect to axis AX4.
Cette goupille 69 coulisse dans une pièce tubulaire 73 qui est elle-même engagée dans un trou 74 de la portion principale 51 , cette pièce tubulaire 73 étant rigidement solidaire de la portion principale 51.This pin 69 slides in a tubular piece 73 which is itself engaged in a hole 74 of the main portion 51, this tubular piece 73 being rigidly secured to the main portion 51.
Cette goupille 69 est équipée d'un ressort de rappel 75 apte à maintenir son extrémité continûment en appui sur la face cylindrique externe 72 du rail 41 , pour que cette extrémité s'engage dans le trou 71 dès qu'elle arrive à son niveau lorsque le chariot 42 est déplacé le long du rail, de manière à bloquer ce chariot 42 au centre de la partie avant de ce rail 41.This pin 69 is equipped with a return spring 75 adapted to keep its end continuously bearing on the outer cylindrical face 72 of the rail 41, so that this end engages in the hole 71 as soon as it reaches its level when the carriage 42 is moved along the rail, so as to block the carriage 42 in the center of the front part of this rail 41.
Concrètement, le ressort de rappel 75 qui est hélicoïdal entoure le corps de la goupille 69 tout en étant situé à l'intérieur de la pièce tubulaire 73. L'une de ses extrémités est en appui sur un chanfrein interne réalisé à l'extrémité libre de la pièce tubulaire 73, et son autre extrémité est en appui sur un chanfrein externe du corps de la goupille 69 qui est situé sensiblement à hauteur de la portion principale 51.Specifically, the return spring 75 which is helical surrounds the body of the pin 69 while being located inside the tubular part 73. One of its ends is supported on an internal bevel made at the free end of the tubular piece 73, and its other end is supported on an outer bevel of the body of the pin 69 which is located substantially at the height of the main portion 51.
L'extrémité libre de la goupille 69, c'est à dire celle qui est la plus éloignée radialement de l'axe de révolution du rail 41 est équipée d'une tête de goupille repérée par 76 qui constitue une butée venant en appui sur l'extrémité de la pièce tubulaire 73 lorsque la goupille est engagée dans le trou correspondant du rail. Avantageusement, des moyens sont prévus pour désactiver la goupille 69, c'est à dire pour la bloquer dans une position où son extrémité est maintenue espacée de la face externe 72 du rail 41 , de sorte qu'elle ne puisse pas bloquer le chariot par rapport au rail.The free end of the pin 69, that is to say the furthest radially from the axis of revolution of the rail 41 is equipped with a pin head marked by 76 which constitutes a stop abutting on the end of the tubular piece 73 when the pin is engaged in the corresponding hole of the rail. Advantageously, means are provided to deactivate the pin 69, ie to block it in a position where its end is kept spaced from the outer face 72 of the rail 41, so that it can not lock the carriage by report to the rail.
Ces moyens peuvent comporter un axe traversant transversalement la goupille 69 en étant situé à proximité de sa tête 76, et deux fentes réalisées à l'extrémité de la pièce tubulaire 73, ces deux fentes ayant une largeur légèrement supérieure au diamètre de l'axe transversal et étant orientées selon l'axe du tube 73 en étant diamétralement opposées autour de cet axe.These means may comprise an axis traversing transversely the pin 69 being located near its head 76, and two slots made at the end of the tubular part 73, these two slots having a width slightly greater than the diameter of the transverse axis and being oriented along the axis of the tube 73 being diametrically opposed about this axis.
Dans ce cas, en fonctionnement normal, l'axe coulisse dans les fentes, ce qui permet à la goupille 69 d'être rappelée par le ressort 75, contre la face 72. Pour bloquer la goupille en position sortie, l'utilisateur la tire et la fait pivoter par exemple d'un quart de tour, pour que les extrémités de l'axe transversal viennent en appui sur la face d'extrémité de la pièce 73, bloquant ainsi la goupille en position sortie.In this case, in normal operation, the axis slides in the slots, which allows the pin 69 to be recalled by the spring 75, against the face 72. To lock the pin in the extended position, the user pulls it and rotates it for example by a quarter of a turn, so that the ends of the transverse axis bear on the end face of the part 73, thus blocking the pin in the extended position.
La portion principale 51 du corps de chariot 49 porte d'autre part la boucle crochet 43. Cette boucle crochet comprend un corps de boucle 77 formé à partir d'une tige ou barre rectiligne, qui est d'abord repliée en son centre en ramenant ses extrémités parallèlement l'une à l'autre pour constituer une boucle. L'extrémité de cette boucle est ensuite rabattue sur elle-même pour lui donner une forme de crochet en vue de profil.The main portion 51 of the carriage body 49 also carries the hook loop 43. This hook loop comprises a loop body 77 formed from a rod or straight bar, which is first folded in its center by reducing its ends parallel to each other to form a loop. The end of this loop is then folded back on itself to give it a hook shape in profile.
Chacune des deux extrémités du corps de boucle 77 est sertie sur une portion de câble inox 78, 79. Un embout ou poinçon est d'autre part serti à chacune des deux extrémités libres des câbles inox, ces deux embouts étant repérés par 81 et 82.Each of the two ends of the loop body 77 is crimped onto a portion of stainless steel cable 78, 79. A tip or punch is also crimped at each of the two free ends of the stainless steel cables, these two ends being marked 81 and 82 .
Les embouts 81 et 82 s'engagent dans des trous complémentaires 83 et 84 prévus au niveau de la portion principale 51 du corps de chariot 49, en étant situés de part et d'autre de son trou central 74, et ils sont fixés à la portion principale 51 par exemple par soudage, les câbles inox 78 et 79 s'étendant ainsi perpendiculairement à cette portion principale 51.The end pieces 81 and 82 engage in complementary holes 83 and 84 provided at the main portion 51 of the carriage body 49, being located on either side of its central hole 74, and they are fixed to the main portion 51 for example by welding, the stainless cables 78 and 79 thus extending perpendicularly to this main portion 51.
Les portions de câbles inox 78 et 79 par lesquelles le corps de boucle 77 est fixé au corps de chariot sont flexibles, de sorte qu'elles permettent au corps de boucle 77 de pivoter par rapport au corps de chariot 49, autour d'un axe parallèle à la tangente au rail 41. De plus, de par leur élasticité en flexion, ces câbles tendent à ramener la boucle crochet dans une position de base médiane correspondant à celle visible dans la figure 4.The stainless wire portions 78 and 79 through which the loop body 77 is attached to the carriage body are flexible, so that they allow the loop body 77 to pivot relative to the carriage body 49 about an axis. parallel to the tangent to the rail 41. Moreover, by their elasticity in bending, these cables tend to return the hook loop to a median base position corresponding to that seen in Figure 4.
La boucle crochet 43 permet à l'utilisateur de s'attacher au câble principal du cerf volant, au moyen d'un anneau à languette articulée représenté aux figures 9 à 11. Cet organe permet de s'accrocher au câble principal sans risque de décrochement intempestif, tout en permettant de se décrocher de façon sûre et rapide en agissant sur la languette articulée.The hook loop 43 allows the user to attach to the main cable of the kite, by means of an articulated tongue ring shown in Figures 9 to 11. This member allows to attach to the main cable without risk of recess untimely, while allowing to get off safely and quickly by acting on the articulated tongue.
Cet organe qui est repéré par 91 dans les figures comporte un anneau 92 qui est solidarisé au câble principal 93 par une embase 94. La languette 96 est articulée en son centre tout en ayant une longueur supérieure au diamètre de l'anneau 92. Cette languette a une extrémité fixée à l'embase 94, pour s'étendre dans le prolongement du câble principal 93, selon un diamètre de l'anneau.This member which is marked 91 in the figures comprises a ring 92 which is secured to the main cable 93 by a base 94. The tongue 96 is articulated at its center while having a length greater than the diameter of the ring 92. This tongue at one end fixed to the base 94, to extend in the extension of the main cable 93, according to a diameter of the ring.
Pour s'accrocher au câble, l'utilisateur engage d'abord le crochet que constitue la boucle crochet 3 ou 43 dans l'anneau 92, comme illustré en figure 9. Il agit ensuite avec sa main 97 sur la languette articulée 96 pour la passer à l'intérieur de la boucle que forme la boucle crochet 3 ou 43, ce qui correspond à la figure 10. Dans cette situation, la languette articulée 96 empêche l'anneau 92 de sortir spontanément de la boucle crochet 3 ou 43, ce qui évite un décrochage intempestif.To hook onto the cable, the user first engages the hook constituting the hook loop 3 or 43 in the ring 92, as illustrated in FIG. 9. He then acts with his hand 97 on the articulated tongue 96 for the pass inside the loop that forms the hook loop 3 or 43, which corresponds to Figure 10. In this situation, the hinged tab 96 prevents the ring 92 from spontaneously out of the hook loop 3 or 43, this which avoids an untimely stall.
Pour se décrocher du câble principal, l'utilisateur exerce avec son pouce une pression dans la région centrale de la languette articulée 96 pour la dégager de la boucle que constitue la boucle crochet 3 ou 43, ce qui correspond à la figure 11. Une fois que la languette a été dégagée, l'utilisateur est libre de sortir l'anneau 92 de la boucle crochet pour se décrocher.To unhook from the main cable, the user exerts with his thumb a pressure in the central region of the articulated tongue 96 to disengage it from the loop constituted by the hook loop 3 or 43, which corresponds to FIG. that the tongue has been released, the user is free to remove the ring 92 of the hook loop to unhook.
L'invention concerne également les différentes variantes ci-après.The invention also relates to the various variants below.
Dans l'exemple de la figure 5, le corps du rail 41 est fabriqué à partir d'un profilé unique à section en T, fourni sous forme rectiligne, et qui est courbé avec une cintreuse. Ses extrémités sont ensuite soudées l'une à l'autre après avoir engagé le chariot, de façon à constituer un anneau à section en T le long duquel coulisse le chariot.In the example of Figure 5, the body of the rail 41 is manufactured from a single section T-section, provided in rectilinear form, and which is bent with a bender. Its ends are then welded to each other after engaging the carriage, so as to form a T-section ring along which slides the carriage.
Ce rail peut aussi être réalisé à partir de plusieurs lames ou profilés à section rectangulaires, concentriques et solidarisées les uns aux autres, comme représenté schématiquement en figure 11. Dans ce cas, le rail 41 est fabriqué à partir de trois lames ou bandes repérées par 101 , 102 et 103 et d'une âme 104, ces quatre éléments étant courbés avec une cintreuse pour constituer des anneaux de diamètres complémentaires s'emboîtant les uns dans les autres.This rail can also be made from a plurality of blades or sections with rectangular section, concentric and joined to each other, as shown schematically in FIG. 11. In this case, the rail 41 is made from three blades or strips marked 101, 102 and 103 and a core 104, these four elements being bent with a bender to form rings of complementary diameters fitting into each other.
Ces trois lames et l'âme rigidificatrice peuvent être solidarisés les unes aux autres par des boulons radiaux, tels que le boulon 106, qui comporte une vis 107 traversant successivement les lames 101 et 102, puis l'âme 104 et la lame 103, un écrou 108 étant serré à l'extrémité de cette vis 107.These three blades and the rigidifying core can be secured to each other by radial bolts, such as bolt 106, which comprises a screw 107 successively passing through the blades 101 and 102, then the core 104 and the blade 103, a nut 108 being tightened at the end of this screw 107.
D'autre part, le rail qui est présenté comme ayant une section en T, dans les figures 5 et 12 peut aussi avoir une section en V ou en Y, comme dans l'exemple de la figure 12. Dans ce cas, le rail 109 définit deux faces d'appui ou bandes de roulement de formes coniques 111 et 112 inclinées à angle droit l'une par rapport à l'autre lorsque vues en section.On the other hand, the rail which is shown as having a T-section, in FIGS. 5 and 12 may also have a V or Y section, as in the example of FIG. 12. In this case, the rail 109 defines two bearing faces or treads of conical shapes 111 and 112 inclined at right angles to each other when viewed in section.
Ce rail 109 est alors utilisé avec un chariot 113 portant des galets 114 et 115 tournant autour d'axes AX6, AX7 inclinés à angle droit de façon à leur permettre de rouler sur ces bandes de roulement. Avantageusement, la boucle crochet non représentée en figure 13 est portée par le corps de chariot par l'intermédiaire d'un support ou embasel 16 qui est apte à pivoter par rapport à ce corps de chariot.This rail 109 is then used with a carriage 113 carrying rollers 114 and 115 rotating about axes AX6, AX7 inclined at right angles so as to allow them to roll on these treads. Advantageously, the hook loop not shown in Figure 13 is carried by the carriage body via a support or embasel 16 which is pivotable relative to the carriage body.
En ce qui concerne le chariot, il est présenté dans les deux modes de réalisation comme portant quatre galets, roulettes ou roulements à billes, deux roulements à billes étant en appui sur une première bande de roulement du rail, deux autres roulements à billes étant en appui sur une seconde bande de roulement du rail.As regards the carriage, it is presented in both embodiments as carrying four rollers, rollers or ball bearings, two ball bearings being supported on a first tread of the rail, two other ball bearings being in position. support on a second tread of the rail.
Le chariot peut aussi être prévu avec uniquement trois roulements à billes. Partant du chariot du second mode de réalisation, les deux premiers sont alors montés aux extrémités de la première portion latérale, comme dans l'exemple des figures 5 à 7 de façon à rouler tous deux sur la première bande de roulement, le troisième roulement à billes étant alors monté au centre de la seconde portion latérale pour rouler sur la seconde bande de roulement. Un montage analogue des roulements à billes est également possible sur le chariot du premier mode de réalisation.The carriage can also be provided with only three ball bearings. Starting from the carriage of the second embodiment, the first two are then mounted at the ends of the first lateral portion, as in the example of FIGS. 5 to 7, so as to both roll on the first tread, the third tread The balls are then mounted in the center of the second lateral portion to roll on the second tread. A similar mounting of the ball bearings is also possible on the carriage of the first embodiment.
Cette solution comportant trois roulements à billes au lieu de quatre permet au chariot d'être en appui isostatique sur le rail, ce qui permet de réduire les tolérances de fabrication de ce chariot, et donc son coût. D'une manière générale, le rail et le chariot du dispositif selon l'invention peuvent être fabriqués en ferronnerie avec de l'inox marin, hormis les roulements à billes que l'on trouve dans le commerce. A titre d'exemple non limitatif, le rail a un diamètre de l'ordre de trente-cinq centimètres.This solution with three ball bearings instead of four allows the carriage to be isostatic support on the rail, which reduces the manufacturing tolerances of this truck, and therefore its cost. In general, the rail and the trolley of the device according to the invention can be made of ironwork with marine stainless steel, except for ball bearings that are commercially available. By way of non-limiting example, the rail has a diameter of the order of thirty-five centimeters.
En ce qui concerne le harnais en matière textile, il peut s'agir d'un harnais de type culotte, ou bien d'un harnais de type dorsal. Dans le cas où il s'agit d'un harnais culotte, le rail solidarisé à ce harnais entoure l'utilisateur au niveau de la ceinture. Dans le cas d'un harnais dorsal, Se rai! entoure l'utilisateur à un niveau situé au dessus de sa ceinture, par exemple au niveau du thorax.Regarding the textile harness, it may be a type of pants harness, or a dorsal type harness. In the case where it is a panty harness, the rail secured to this harness surrounds the user at the waist. In the case of a back harness, Se rai! surrounds the user at a level above his belt, for example at the level of the thorax.
L'invention apporte notamment les avantages suivants :The invention notably provides the following advantages:
Les moyens de blocage que constituent la goupille et les trous associés permettent de bloquer le chariot dans une position unique par rapport au rail, cette position de référence étant avantageusement située au centre de la partie avant du rail. L'utilisateur peut alors utiliser le dispositif comme un dispositif classique, dès lors qu'il a bloqué le chariot par rapport au rail.The locking means that constitute the pin and the associated holes to lock the carriage in a single position relative to the rail, this reference position being advantageously located in the center of the front portion of the rail. The user can then use the device as a conventional device, since it has blocked the carriage relative to the rail.
Les moyens de rappel de la goupille permettent de bloquer automatiquement le chariot dans la position de référence lorsqu'il passe à cette position, la goupille s'engageant alors spontanément dans le rail. La possibilité de bloquer la goupille en position sortie permet à un utilisateur maîtrisant le dispositif d'enchaîner des figures.The return means of the pin automatically lock the carriage in the reference position when it passes to this position, the pin then engaging spontaneously in the rail. The ability to lock the pin in the extended position allows a user mastering the device to link figures.
La boucle crochet permet à l'utilisateur de s'accrocher de façon fiable au câble principal le reliant au cerf volant, sans risque de décrochage intempestif, et tout en conservant la possibilité de se décrocher de façon rapide et sûre en cas de besoin.The hook loop allows the user to reliably hook onto the main cable connecting it to the kite, without the risk of unintentional stall, and while maintaining the ability to unhook quickly and safely when needed.
La solidarisation de la boucle crochet au corps de chariot par une liaison permettant à cette boucle de pivoter autour d'un axe tangent au rail permet de réduire le moment de efforts appliqués par la boucle crochet au chariot, par rapport à l'axe de déplacement du chariot. Le risque d'arc boutement du chariot sur le rail est ainsi diminué pour faciliter son glissement le long du rail en toute situation.The fastening of the hook loop to the carriage body by a connection allowing this loop to pivot about an axis tangential to the rail makes it possible to reduce the moment of forces applied by the hook loop to the carriage, relative to the axis of displacement. of the cart. The risk of bow thrust of the carriage on the rail is thus reduced to facilitate its sliding along the rail in any situation.
Ce risque d'arc boutement peut encore être diminué en utilisant un profilé du type en Y, comme illustré sur la figure 13, dans lequel l'arc boutement du chariot est impossible tant que le câble du cerf volant reste dans un secteur angulaire de quatre- vingt dix degrés délimité par les normales aux bandes de roulement 111 et 112. Le fait que les galets ou roulements à billes du chariot soient en appui sur des bandes de roulement cylindriques ou coniques, c'est-à-dire localement planes vis-à-vis des galets ou roulements à billes améliore le coulissement du chariot le long du rail.This risk of thrust bow can be further reduced by using a Y-shaped profile, as illustrated in FIG. 13, in which the trolley can not bow as long as the kite cable remains in an angular sector of four. - twenty-ten degrees delimited by the normals to treads 111 and 112. The fact that the rollers or ball bearings of the carriage rest on cylindrical or conical treads, that is to say locally flat against the rollers or ball bearings improves the sliding of the trolley along of the rail.
La structure de la section du rail, qui comporte en section des portions inclinées par rapport à l'axe de symétrie du rail lui confère une rigidité en flexion importante, sans pénaliser ni son poids ni son encombrement. Cette rigidité qui diminue la flexion du rai! dans son plan de référence contribue à améliorer significativement le coulissement du chariot le long de ce rail.The structure of the section of the rail, which comprises in section portions inclined relative to the axis of symmetry of the rail gives it a high flexural rigidity, without penalizing either its weight or its size. This rigidity which reduces the flexion of the spoke! in its reference plane contributes to significantly improve the sliding of the carriage along this rail.
D'une manière générale, dans son utilisation sous traction, seuls les roulements à billes sont en contact avec des bandes de roulement du rail qui est rigide, ce qui offre un coulissement très fluide du chariot le long du rail.In general, in its use under traction, only the ball bearings are in contact with treads of the rail which is rigid, which provides a very smooth sliding of the carriage along the rail.
Le dispositif selon l'invention est utilisable dans le cadre de différents sports aérotractés, que se soit sur l'eau comme le kitesurf, sur la neige comme le snow-kite ou sur la terre comme le kite-mountainboard, le buggy-kite ou le roller-kite. The device according to the invention can be used in the context of various aerotracted sports, whether on the water such as kitesurfing, on snow like snow-kite or on land such as kite-mountainboard, buggy-kite or roller-kite.
