Description
Dispositif de fixation et de renfort de voile, son procédé de fabrication et voile équipée d'un tel dispositif. Device for fixing and reinforcing a sail, its manufacturing process and sail equipped with such a device.
La présente invention se rapporte à un dispositif de fixation et de renfort de voile pour une embarcation à voile telle qu'une planche à voile ou un voilier léger. L'invention concerne également un procédé de fabrication d'un tel dispositif ainsi qu'une voile équipée d'au moinsTrn dispositif de fixation et de renfort de ce type.The present invention relates to a device for fixing and reinforcing a sail for a sailing boat such as a windsurfing board or a light sailboat. The invention also relates to a method of manufacturing such a device as well as a sail equipped with at leastTrn fixing device and reinforcement of this type.
Les voiles comportent habituellement à leurs angles (point de drisse, point d'armure, point d'écoute dans le cas d'une voile de forme générale triangulaire) des renforts de fixation formés d'un oeillet de fixation et de plusieurs morceaux de tissu superposés cousus sur une ou sur les deux faces de la voile de manière que l'épaisseur des renforts diminue graduellement vers le centre de la voile, cela afin d'éviter des amorces de déchirure sur la voile. Dans le même but, les ralingues grâce auxquelles les voiles peuvent coulisser sur le mât comprennent habituellement un morceau de tissu emprisonnant un cordage et cousu sur la voile.The sails usually have at their angles (halyard stitch, point of armor, point of listening in the case of a sail of generally triangular shape) fixing reinforcements formed by a fixing eyelet and several pieces of fabric superimposed sewn on one or on both sides of the sail so that the thickness of the reinforcements gradually decreases towards the center of the sail, this in order to avoid tears starting on the sail. For the same purpose, the ropes with which the sails can slide on the mast usually include a piece of fabric trapping a rope and sewn on the sail.
Les principaux inconvénients de tous ces dispositifs de fixation et de renfort connus résident dans leur coût (une ou plusieurs épaisseurs de tissu à fixer sur la voile) et dans le fait que leur fixation à la voile par couture entraîne une fragilisation de la voile. Dans le cas des ralingues, la présence du cordage ne permet par ailleurs pas de choisir à volonté le profil de guidage sur le mât, et le tissu des ralingues subit inévitablement une usure rapide sous l'effet du coulissement dans le profilé de guidage du mât.The main drawbacks of all these known fastening and reinforcement devices lie in their cost (one or more thicknesses of fabric to be fixed on the sail) and in the fact that their attachment to the sail by sewing leads to embrittlement of the sail. In the case of ropes, the presence of the rope does not also allow the guide profile to be chosen at will on the mast, and the fabric of the ropes inevitably undergoes rapid wear under the effect of sliding in the guide profile of the mast. .
La présente invention vise un dispositif de fixation et de renfort de voile qui soit simple à fabriquer et à poser sur une voile et ne fragilise par la voile.The present invention relates to a device for fixing and reinforcing a sail which is simple to manufacture and to place on a sail and does not weaken by sailing.
L'invention vise par ailleurs une ralingue qui, de plus, permette une adaptation optimale au profil de guidage sur le mât et ne soit pas l'objet d'une usure rapide. L'invention vise également un procédé particulièrement simple de fabrication de tels dispositifs de fixation et de renfort de conformations différentes.The invention also relates to a rope which, in addition, allows optimal adaptation to the guide profile on the mast and is not subject to rapid wear. The invention also relates to a particularly simple method of manufacturing such fastening and reinforcement devices of different conformations.
Enfin, l'invention vise une voile équipée d'au moins un dispositif de fixation et de renfort de ce type. Le dispositif de fixation et de renfort de voile objet de la présente invention comprend des moyens de fixation et des moyens de renfort qui s'étendent depuis les moyens de fixation vers l'intérieur de la voile. Les moyens de renfort sont constitués d'une seule pièce en matière plastique avec les moyens de fixation sous la forme d'au moins une partie de renfort s'étendant avec une épaisseur dégressive depuis les moyens de fixation vers l'intérieur de la voile.Finally, the invention relates to a sail fitted with at least one fixing and reinforcing device of this type. The sail fastening and reinforcement device which is the subject of the present invention comprises fastening means and reinforcement means which extend from the fastening means towards the interior of the sail. The reinforcing means consist of a single piece of plastic material with the fixing means in the form of at least one reinforcing part extending with a decreasing thickness from the fixing means towards the interior of the sail.
Suivant un mode de réalisation préféré, les moyens de renfort sont constitués d'une seule pièce en matière plastique avec les moyens de fixation sous la forme de deux parties de renfort complémentaires s'étendant avec une épaisseur dégressive depuis une partie commune de liaison comprenant les moyens de fixation vers l'intérieur de la voile.According to a preferred embodiment, the reinforcing means consist of a single piece of plastic material with the fixing means in the form of two complementary reinforcing parts extending with a decreasing thickness from a common connecting part comprising the fixing means towards the interior of the sail.
Le dispositif de fixation et de renfort selon l'invention peut être réalisé sous forme de renfort d'angle avec un oeillet de fixation, par exemple un oeillet métallique surmoulé dans la partie de liaison, ou également sous forme de ralingue avec une partie guidée moulée d'une seule pièce avec la partie de liaison.The fixing and reinforcement device according to the invention can be produced in the form of a corner reinforcement with a fixing eyelet, for example a metal eyelet overmolded in the connecting part, or also in the form of a rope with a molded guided part. in one piece with the connecting part.
Dans ce dernier cas, la partie guidée peut être moulée avec un profil adapté selon les besoins au profil de guidage prévu sur le mât. Le dispositif de fixation et de renfort selon l'invention, du fait de sa réahsation en matière plastique, peut être avantageusement fixé à la voile par collage et/ou par soudage.In the latter case, the guided part can be molded with a profile adapted as necessary to the guide profile provided on the mast. The fixing and reinforcement device according to the invention, due to its reahsation in plastic material, can advantageously be fixed to the sail by gluing and / or welding.
Le procédé de fabrication selon l'invention concerne, suivant un premier aspect, la fabrication d'un dispositif de fixation et de renfort d'angle et consiste à mouler une ébauche avec deux parties de renfort ayant un contour correspondant à une courbe fermée autour des moyens de fixation et à découper ensuite dans cette ébauche une pièce sensiblement en forme de secteur contenant les moyens de fixation.The manufacturing method according to the invention relates, according to a first aspect, the manufacture of a fixing device and corner reinforcement and consists in molding a blank with two parts of reinforcement having a contour corresponding to a closed curve around the fixing means and then to cut from this blank a part substantially in the form of a sector containing the fixing means.
En moulant cette ébauche avec un contour correspondant à un cercle, les moyens de fixation se trouvant au centre du cercle, il est possible de découper dans l'ébauche des pièces en forme de secteur d'angle quelconque, mais de même rayon.By molding this blank with a contour corresponding to a circle, the fixing means being in the center of the circle, it is possible to cut from the blank parts in the form of a sector of any angle, but of the same radius.
En moulant l'ébauche avec un contour correspondant à un cercle, les moyens de fixation se trouvant en position excentrée, il est possible de découper dans une même ébauche des pièces ayant non seulement des angles différents, mais également des rayons différents.By molding the blank with a contour corresponding to a circle, the fixing means being in the eccentric position, it is possible to cut from the same blank parts not only having different angles, but also different radii.
En moulant l'ébauche avec un contour correspondant à une courbe fermée de rayon variable telle qu'une ellipse, un ovale ou analogue, il est possible de faire varier encore davantage les rayons des pièces susceptibles d'être découpées dans une ébauche.By molding the blank with a contour corresponding to a closed curve of variable radius such as an ellipse, an oval or the like, it is possible to vary the radii of the parts which can be cut out of a blank even more.
Le procédé de fabrication selon l'invention, suivant un second aspect, concerne la fabrication d'un dispositif de fixation et de renfort du type ralingue et consiste à extrader un profilé continu comprenant les parties de renfort et la partie commune de liaison avec la partie guidée et à couper à longueur ce profilé en fonction de la voile à équiper.The manufacturing method according to the invention, according to a second aspect, relates to the manufacture of a fixing and reinforcement device of the rope type and consists in extruding a continuous profile comprising the reinforcing parts and the common part connecting with the part guided and cut to length this profile according to the sail to be fitted.
La voile objet de la présente invention qui peut être une voile tissée classique formée de panneaux cousus ou de préférence une voile tridimensionnelle monopièce thermoformée comprend au moins un dispositif de fixation et de renfort tel que défini ci-dessus, fixé de préférence par collage et/ou soudage à la voile.The sail which is the subject of the present invention which may be a conventional woven sail formed from sewn panels or preferably a three-piece thermoformed sail comprises at least one fixing and reinforcement device as defined above, preferably fixed by gluing and / or sail welding.
En se référant aux dessins annexés, on va décrire ci-après plus en détail plusieurs exemples de réalisation non limitatifs d'un dispositif de fixation et de renfort selon l'invention, ainsi que le procédé de fabrication correspondant; sur les dessins:With reference to the accompanying drawings, several non-limiting exemplary embodiments of a fixing and reinforcement device according to the invention will be described below in more detail, as well as the corresponding manufacturing process; on the drawings:
- la figure 1 représente sur une voile l'emplacement des différents dispositifs de fixation et de renfort objet de la présente invention;- Figure 1 shows on a sail the location of the various fastening and reinforcement devices object of the present invention;
- les figures 2 et 3 représentent deux exemples d'un dispositif de fixation et de renfort d'angle selon l'invention; - la figure 4 illustre la possibilité de découpage de pièces en forme de secteur de rayons et d'angles différents dans une même ébauche, et- Figures 2 and 3 show two examples of a fixing device and corner reinforcement according to the invention; FIG. 4 illustrates the possibility of cutting parts in the form of a sector of different radii and angles in the same blank, and
- la figure 5 représente un dispositif selon l'invention formant ralingue.- Figure 5 shows a device according to the invention forming a rope.
Une voile 1 telle qu'illustrée schématiquement à titre d'exemple par la figure 1 comporte trois dispositifs de fixation et de renfort d'angle 2a, 2b, 2c respectivement au point de drisse, au point d'amure et au point d'écoute, ainsi qu'un dispositif de fixation et de renfort allongé 3 formant ralingue sur le bord avant, pour coopérer avec un profil de guidage non représenté sur le mât d'une embarcation à voile.A sail 1 as illustrated schematically by way of example in FIG. 1 comprises three fastening and corner reinforcement devices 2a, 2b, 2c respectively at the halyard point, at the tack point and at the listening point , as well as an elongated fixing and reinforcement device 3 forming a rope on the front edge, for cooperating with a guide profile not shown on the mast of a sailing boat.
Tel que cela apparaît sur les figures 2 et 3 illustrant deux exemples d'un dispositif de fixation et de renfort d'angle 2, ce dernier comprend un moyen de fixation 4 constitué par exemple par un oeillet métallique destiné à recevoir un "bout" (cordage) ou une manille, et deux parties de renfort 5 complémentaires réunies entre elles à l'endroit du moyen de fixation 4 par une partie commune de liaison 6 contenant le moyen de fixation 4. Les deux parties de renfort 5 s'étendent depuis la partie de liaison 6 sensiblement en forme de secteur sous la forme de deux lames plates, dont l'épaisseur est progressivement décroissante depuis la partie de liaison 6 jusqu'au bord 7 opposé. Les deux parties de renfort 5 sont parallèles et légèrement espacées l'une de l'autre, délimitant entre elles un intervalle 8 qui correspond sensiblement à l'épaisseur de la voile à laquelle est destiné le dispositif 2 et qui s'arrête avant le moyen de fixation 4 (oeillet). L'angle du secteur compris entre les deux autres bords opposés 9 et 10 rectilignes constituant deux rayons partant de la partie de liaison 6 est fonction de l'angle que la voile présente à l'endroit où le dispositif 2 doit être fixé.As shown in Figures 2 and 3 illustrating two examples of a fixing device and corner reinforcement 2, the latter comprises a fixing means 4 constituted for example by a metal eyelet intended to receive a "tip" ( rope) or a shackle, and two complementary reinforcing parts 5 joined together at the location of the fixing means 4 by a common connecting part 6 containing the fixing means 4. The two reinforcing parts 5 extend from the connecting part 6 substantially in the form of a sector in the form of two flat blades, the thickness of which is progressively decreasing from the connecting part 6 to the opposite edge 7. The two reinforcing parts 5 are parallel and slightly spaced from each other, delimiting between them a gap 8 which corresponds substantially to the thickness of the sail for which the device 2 is intended and which stops before the means fastening 4 (eyelet). The angle of the sector between the two other opposite straight edges 9 and 10 constituting two radii starting from the connecting part 6 is a function of the angle that the sail has at the place where the device 2 must be fixed.
Selon la figure 2, les deux bords 9 et 10 ont la même longueur, le dispositif 2 ayant sensiblement la forme d'un secteur de cercle, tandis que selon la figure 3, les deux bords 9 et 10 sont de longueurs différentes, le dispositif 2 ayant sensiblement la forme d'un secteur d'ellipse ou d'une autre figure géométrique définie par une courbe fermée de courbure variable.According to FIG. 2, the two edges 9 and 10 have the same length, the device 2 having substantially the shape of a sector of a circle, while according to FIG. 3, the two edges 9 and 10 are of different lengths, the device 2 having substantially the shape of an ellipse sector or of another geometrical figure defined by a closed curve with variable curvature.
Les dispositifs 2 tels qu'illustrés par les figures 2 et 3 peuvent être fabriqués à partir de toute matière plastique appropriée, de préférence un polyéthylène téréphtalate (PET) ou polypropylène (PP) ou une matère similaire, éventuellement renforcée de fibres, directement par un procédé de moulage tel que l'injection, dans des moules de formes correspondantes. Cela implique la prévision d'un moule spécifique pour chaque taille et chaque forme d'un tel dispositif. La figure 4 illustre un mode de fabrication permettant de réduire de manière significative le nombre de moules nécessaires pour réaliser des dispositifs 2 de tailles et de formes différentes.The devices 2 as illustrated in FIGS. 2 and 3 can be manufactured from any suitable plastic material, preferably a polyethylene terephthalate (PET) or polypropylene (PP) or a similar material, possibly reinforced with fibers, directly by a molding process such as injection, in molds of corresponding shapes. This implies the provision of a specific mold for each size and each shape of such a device. FIG. 4 illustrates a manufacturing method making it possible to significantly reduce the number of molds necessary to produce devices 2 of different sizes and shapes.
Ce procédé consiste à mouler des ébauches 11 identiques en forme de figure géométrique définie par une courbe fermée qui peut être par exemple un cercle, une ellipse comme dans l'exemple représenté ou toute autre figure définie par une courbe fermée de courbure variable, chaque ébauche 11 étant constituée par deux parties de renfort 5 ayant la forme de cette figure complète, réunies entre elles à l'endroit du moyen de fixation 4 (par exemple oeillet surmoulé) par une partie de liaison 6 disposée en position excentrée par rapport au contour de l'ébauche 11. Dans ces ébauches 11, il est ensuite possible de découper à volonté des pièces en forme de secteur avec des angles et des rayons différents, constituant des dispositifs 2 de formes et de tailles différentes, par exemple une pièce de forme sensiblement symétrique et de faible rayon telle qu'esquissée en pointillés, une pièce de forme sensiblement symétrique et de grand rayon telle qu'esquissée en tirets, une pièce asymétrique de rayon variable telle qu'esquissée en traits mixtes, ou une pièce de toute autre forme appropriée. Selon la figure 5, un dispositif de fixation et de renfort 3 conforme à l'invention de forme allongée, servant de ralingue, comprend deux parties de renfort 12 complémentaires réunies entre elles par une partie commune de liaison 13 conformée en partie de fixation, c'est-à-dire comportant une portion 14 profilée de manière à pouvoir être guidée dans un profil de guidage prévu sur la mât, en étant mobile en translation longitudinale dans ce profilé. Les deux parties de renfort 12 s'étendent depuis depuis un côté de la partie de liaison 13 sous la forme de deux lames plates, rectangulaires, dont l'épaisseur est progressivement décroissante depuis la partie de liaison 13 jusqu'au bord 15 opposé qui est rectiligne et parallèle à la partie de liaison 13. Les deux parties de renfort 12 sont parallèles et légèrement espacées l'une de l'autre, délimitant entre elles un intervalle 16 qui correspond sensiblement à l'épaisseur de la voile à laquelle est destiné le dispositif 3. II est à noter que la portion guidée 14 du dispositif 3, au lieu d'être de profil circulaire comme dans l'exemple illustré, pourrait avoir tout autre profil approprié, adapté au profil de guidage prévu sur le mât pour le recevoir, pour lui permettre d'assumer au mieux ses fonctions, notamment de maintenir le bord de la voile par rapport au mât, tout favorisant son coulissement dans le profil de guidage. La portion guidée 14 pourrait ainsi présenter avantageusement une forme ovale, la grand axe de l'ovale étant perpendiculaire aux parties de renfort 12, ou toute autre forme semblable.This method consists in molding identical blanks 11 in the form of a geometric figure defined by a closed curve which may for example be a circle, an ellipse as in the example shown or any other figure defined by a closed curve of variable curvature, each blank 11 being constituted by two reinforcing parts 5 having the shape of this complete figure, joined together at the location of the fixing means 4 (for example overmolded eyelet) by a connecting part 6 arranged in an eccentric position relative to the contour of the blank 11. In these blanks 11, it is then possible to cut at will pieces in the shape of a sector with different angles and radii, constituting devices 2 of different shapes and sizes, for example a piece of substantially shaped symmetrical and of small radius as sketched in dotted lines, a piece of substantially symmetrical shape and of large radius as sketched in t irets, an asymmetrical piece of variable radius as sketched in phantom, or a piece of any other suitable shape. According to FIG. 5, a fixing and reinforcing device 3 in accordance with the invention of elongated shape, serving as a rope, comprises two complementary reinforcing parts 12 joined together by a common connecting part 13 shaped as a fixing part, c that is to say comprising a portion 14 profiled so as to be able to be guided in a guide profile provided on the mast, in being movable in longitudinal translation in this profile. The two reinforcing parts 12 extend from one side of the connecting part 13 in the form of two flat, rectangular blades, the thickness of which is progressively decreasing from the connecting part 13 to the opposite edge 15 which is straight and parallel to the connecting part 13. The two reinforcing parts 12 are parallel and slightly spaced from each other, delimiting between them a gap 16 which corresponds substantially to the thickness of the sail for which the device 3. It should be noted that the guided portion 14 of the device 3, instead of being of circular profile as in the example illustrated, could have any other suitable profile, adapted to the guide profile provided on the mast to receive it , to allow it to better assume its functions, in particular to maintain the edge of the sail relative to the mast, while promoting its sliding in the guide profile. The guided portion 14 could thus advantageously have an oval shape, the major axis of the oval being perpendicular to the reinforcing parts 12, or any other similar shape.
Le dispositif 3 peut être fabriqués à partir de toute matière plastique appropriée, de préférence un polypropylène, éventuellement renforcée par exemple de fibres, soit par moulage, soit de préférence par tronçonnage, c'est-à-dire par coupe à longueur d'un profilé correspondant qui peut être extradé en continu.The device 3 can be manufactured from any suitable plastic material, preferably polypropylene, possibly reinforced for example with fibers, either by molding or preferably by cutting, that is to say by cutting to length corresponding profile which can be continuously extradited.
Les dispositifs de fixation et de renfort 2 et 3 peuvent être fixés d'une manière simple et rapide aux voiles auxquelles ils sont destinés, de préférence par collage et/ou soudage, mais également par couture. Les voiles en question peuvent être soit des voiles tissées classiques formées de panneaux cousus ou assemblés d'une autre manière, soit de préférence des voiles tridimensionnelles monopièces thermoformées (voir par exemple les documents EP-A-0 475 083 et WO-A-01/00487).The fastening and reinforcement devices 2 and 3 can be fixed in a simple and rapid manner to the sails for which they are intended, preferably by gluing and / or welding, but also by sewing. The sails in question can either be conventional woven sails formed from panels sewn or otherwise assembled, or preferably three-dimensional thermoformed sails (see for example documents EP-A-0 475 083 and WO-A-01 / 00487).
Au lieu d'être fabriqués, comme selon les exemples de réalisation illustrés, d'une seule pièce avec deux parties de renfort 5 ou 12 complémentaires, qui prennent entre elles la voile, le dispositif de fixation et de renfort 2 ou 3 pourrait également être fabriquée en deux parties qui sont alors assemblées sur la voile au moment de leur fixation à cette dernière.Instead of being manufactured, as according to the illustrated exemplary embodiments, in one piece with two complementary reinforcing parts 5 or 12, which take the sail between them, the fixing and reinforcing device 2 or 3 could also be made in two parts which are then assembled on the sail at the time of their attachment to the latter.
Enfin, notamment les dispositifs de fixation et de renfort 3 formant ralingue pourraient être fabriqués d'une seule pièce avec une partie de renfort 12 qui, au lieu d'être parallèle à l'autre partie de renfort 12, peut faire un angle plus ou moins aigu avec cette dernière, ce qui facilite éventuellement la fabrication. Les deux parties de renfort 12 sont alors amenées en position parallèle au moment de la fixation à la voile. L'invention est par ailleurs applicable également à d'autres dispositifs de fixation et de renfort de voiles, par exemple ceux communément appelés renforts de ris, servant à la fixation sur des voiles partiellement affalées. Finally, in particular the fixing and reinforcing devices 3 forming a rope could be made in one piece with a reinforcing part 12 which, instead of being parallel to the other reinforcing part 12, can make an angle more or less acute with the latter, which eventually facilitates manufacturing. The two reinforcing parts 12 are then brought into a parallel position at the time of attachment to the sail. The invention is also applicable also to other fastening and reinforcement devices for sails, for example those commonly known as reef reinforcements, used for fixing on partially collapsed sails.
