Planche de surf pour trampolineSurfboard for trampoline
Domaine technique de l'inventionTechnical field of the invention
L'invention concerne une planche de surf pour sauts sur trampoline.The invention relates to a surfboard for jumping on a trampoline.
État de la techniqueState of the art
Pour la pratique du surf des neiges hors saison d'hiver, beaucoup d'utilisateurs souhaitent des appareils pour s'entraîner et améliorer leur technique. Ainsi, il est connu d'adapter une planche de surf à l'usage d'un trampoline, pour permettre aux pratiquants de surf de réaliser des figures, de travailler leurs appuis, ainsi que leurs prises d'impulsion.For the practice of snowboarding outside the winter season, many users want devices to train and improve their technique. Thus, it is known to adapt a surfboard to the use of a trampoline, to allow surfers to perform tricks, to work on their supports, as well as their impulses.
Toutes les planches de surf pour trampoline connues (notamment par les documents US-A-2002/0077222, FR-A-2831452, US 6196558) comportent une partie centrale plane, sur laquelle viennent se poser les fixations, et deux extrémités éventuellement relevées, de manière à imiter parfaitement une planche de surf. Cependant, le poids élevé et la configuration particulière d'une telle planche de surf engendrent souvent une dégradation du filet du trampoline, après une utilisation prolongée. Une telle planche s'avère également très peu maniable et difficile à utiliser, ce qui réduit le temps d'entraînement. Objet de l'inventionAll known trampoline surfboards (in particular by documents US-A-2002/0077222, FR-A-2831452, US 6196558) have a flat central part, on which the bindings come to rest, and two ends which may be raised, so as to perfectly imitate a surfboard. However, the high weight and the particular configuration of such a surfboard often cause degradation of the trampoline net, after prolonged use. Such a board also turns out to be very unwieldy and difficult to use, which reduces the training time. Subject of the invention
L'invention a pour but de remédier à ces inconvénients et a pour objet la réalisation d'une planche de surf pour sauts sur trampoline, légère, maniable et offrant un contact non agressif et inusable pour le filet du trampoline.The invention aims to remedy these drawbacks and relates to the production of a surfboard for jumping on a trampoline, light, handy and offering non-aggressive and wear-free contact for the trampoline net.
Selon l'invention, ce but est atteint par le fait que la planche de surf comporte un cadre tubulaire, de section sensiblement circulaire, ayant longitudinalement un rayon de courbure prédéterminé, et au moins une platine de fixation, solidaire du cadre tubulaire.According to the invention, this object is achieved by the fact that the surfboard comprises a tubular frame, of substantially circular section, having longitudinally a predetermined radius of curvature, and at least one fixing plate, integral with the tubular frame.
Selon un mode de réalisation de l'invention, le cadre tubulaire comporte deux longerons latéraux parallèles courbes connectés, par des moyens d'assemblage, à deux coudes d'extrémité.According to one embodiment of the invention, the tubular frame comprises two parallel curved side rails connected, by means of assembly, to two end bends.
Selon une variante de réalisation de l'invention, le cadre tubulaire comporte deux éléments identiques, ayant ledit rayon de courbure, comportant chacun une branche longitudinale prolongée par un coude d'extrémité, une extrémité libre de la branche longitudinale de l'un des éléments étant connectée à une extrémité libre du coude d'extrémité de l'autre élément, par l'intermédiaire de moyens d'assemblage.According to an alternative embodiment of the invention, the tubular frame comprises two identical elements, having said radius of curvature, each comprising a longitudinal branch extended by an end bend, a free end of the longitudinal branch of one of the elements being connected to a free end of the end bend of the other element, by means of assembly means.
Selon un développement de l'invention, chaque platine de fixation comporte une surface de support plane, surélevée par rapport au cadre tubulaire. Description sommaire des dessinsAccording to a development of the invention, each fixing plate comprises a flat support surface, raised relative to the tubular frame. Brief description of the drawings
D'autres avantages et caractéristiques ressortiront plus clairement de la description qui va suivre de modes particuliers de réalisation de l'invention donnés à titre d'exemples non limitatifs et représentés aux dessins annexés, dans lesquels :Other advantages and characteristics will emerge more clearly from the description which follows of particular embodiments of the invention given by way of nonlimiting examples and represented in the appended drawings, in which:
La figure 1 est une vue en perspective d'un premier mode de réalisation d'une planche de surf selon l'invention. La figure 2 est une vue de profil de la planche de surf selon la figure 1.Figure 1 is a perspective view of a first embodiment of a surfboard according to the invention. FIG. 2 is a side view of the surfboard according to FIG. 1.
La figure 3 représente une vue en perspective d'un autre mode de réalisation d'une planche de surf selon l'invention.FIG. 3 represents a perspective view of another embodiment of a surfboard according to the invention.
Description de modes particuliers de réalisationDescription of particular embodiments
Sur les figures 1 et 2, la planche de surf d'entraînement 1 , destinée à recevoir, par exemple, une paire de fixations et de chaussures conventionnelles (non représentées) comporte un cadre tubulaire 2, ayant sensiblement la forme d'une planche de surf traditionnelle. Le cadre tubulaire 2 a iongitudinalement un rayon de courbure prédéterminé constant, permettant de s'adapter efficacement au filet d'un trampoline, lorsque celui-ci subit une déformation sous l'impulsion d'un utilisateur.In FIGS. 1 and 2, the training surfboard 1, intended to receive, for example, a pair of bindings and conventional shoes (not shown) comprises a tubular frame 2, having substantially the shape of a traditional surfing. The tubular frame 2 iongitudinally has a constant predetermined radius of curvature, making it possible to adapt effectively to the net of a trampoline, when the latter undergoes deformation under the impulse of a user.
Le cadre tubulaire 2 comporte une paire de longerons 3 latéraux parallèles courbes, disposés en vis-à-vis, connectés, par exemple, par l'intermédiaire de rivets, à une paire de coudes d'extrémité 4 identiques, formant les extrémités arrondies latérales de la planche de surf 1 (figure 1). Selon la figure 2, les longerons 3 et les coudes d'extrémité 4 sont cintrés selon un rayon de courbure déterminé, définissant la courbure générale longitudinale du cadre tubulaire 2. La planche de surf 1 a donc un rayon de courbure constant tout le long du cadre tubulaire 2. Ce rayon correspond à la déformation moyenne subie par une planche de surf des neiges, lors de la prise d'impulsion de son utilisateur, notamment lors d'un saut dans le creux d'une bosse. À titre d'exemple, pour une longueur de planche 1 de l'ordre de 1200mm et une largeur de planche 1 de l'ordre de 265mm, le rayon de courbure du cadre tubulaire 2 est de l'ordre de 1610mm.The tubular frame 2 comprises a pair of curved parallel lateral side rails 3, disposed opposite, connected, for example, by means of rivets, to a pair of identical end bends 4, forming the rounded side ends of surfboard 1 (figure 1). According to FIG. 2, the longitudinal members 3 and the end bends 4 are bent according to a determined radius of curvature, defining the general longitudinal curvature of the tubular frame 2. The surfboard 1 therefore has a constant radius of curvature all along the tubular frame 2. This radius corresponds to the average deformation undergone by a snowboard, during the taking of impulse of its user, in particular during a jump in the hollow of a bump. For example, for a length of board 1 of the order of 1200mm and a width of board 1 of the order of 265mm, the radius of curvature of the tubular frame 2 is of the order of 1610mm.
Dans le cadre d'une utilisation sur un trampoline, ce type de planche 1 courbée présente une plus grande stabilité qu'une planche rigide plate de même longueur. L'entraînement peut durer plus longtemps sur le trampoline, car l'utilisateur est sollicité physiquement de façon plus réaliste et moins contraignante. Par ailleurs, la forme courbée de la planche empêche les projections latérales violentes dues à un mauvais appui lors d'une impulsion.When used on a trampoline, this type of curved board 1 has greater stability than a rigid flat board of the same length. The training can last longer on the trampoline because the user is physically more realistic and less demanding. Furthermore, the curved shape of the board prevents violent lateral projections due to poor support during an impulse.
Les longerons 3 et les coudes d'extrémité 4 du cadre tubulaire 2 sont assemblés au moyen de rivets métalliques ou de tout autre moyen d'assemblage mécanique approprié, comme le boulonnage ou la soudure. Dans le cas d'un assemblage par rivets métalliques, ceux-ci sont disposés, de préférence, vers le haut, à savoir sur le dessus du cadre tubulaire 2, de manière à ne pas entrer en contact avec le filet du trampoline pour éviter toute détérioration.The side members 3 and the end bends 4 of the tubular frame 2 are assembled by means of metal rivets or any other suitable mechanical assembly means, such as bolting or welding. In the case of an assembly by metal rivets, these are preferably arranged upwards, namely on the top of the tubular frame 2, so as not to come into contact with the net of the trampoline to avoid any deterioration.
Afin d'offrir une grande rigidité et un poids réduit, les longerons 3 et les coudes d'extrémité 4 sont des tubes, de préférence, creux de section circulaire, par exemple, en carbone ou en aluminium. À titre d'exemple, le cadre tubulaire 2 est sensiblement cylindrique en aluminium soudable, avec un diamètre de l'ordre de 30mm et une épaisseur de paroi de l'ordre de 2mm. Dans la variante de réalisation représentée sur la figure 3, la planche de surf 1 se distingue de celle représentée sur les figures 1 et 2 par les éléments constituants le cadre tubulaire 2. En effet, le cadre tubulaire 2 comporte deux éléments 5a, 5b identiques, comportant chacun, respectivement, une branche longitudinale 6a, 6b et un coude d'extrémité 7a, 7b. La branche longitudinale 6a du premier élément 5a est connectée à une extrémité libre du coude d'extrémité 7b du second élément 5b, tandis que la branche longitudinale 6b du second élément 5b est connectée à une extrémité libre du coude d'extrémité 7a du premier élément 5a.In order to offer great rigidity and a reduced weight, the longitudinal members 3 and the end bends 4 are preferably hollow tubes of circular section, for example, made of carbon or aluminum. For example, the tubular frame 2 is substantially cylindrical in weldable aluminum, with a diameter of around 30mm and a wall thickness of around 2mm. In the alternative embodiment shown in FIG. 3, the surfboard 1 differs from that shown in FIGS. 1 and 2 by the elements constituting the tubular frame 2. In fact, the tubular frame 2 comprises two identical elements 5a, 5b , each comprising, respectively, a longitudinal branch 6a, 6b and an end bend 7a, 7b. The longitudinal branch 6a of the first element 5a is connected to a free end of the end bend 7b of the second element 5b, while the longitudinal branch 6b of the second element 5b is connected to a free end of the end bend 7a of the first element 5a.
Les branches longitudinales 6a, 6b et les coudes d'extrémité 7a, 7b sont assemblés, par exemple, par soudage, pour assurer une rigidité optimale au cadre tubulaire 2. Par ailleurs, les extrémités de la branche longitudinale 6a et du coude d'extrémité 7a du premier élément 5a peuvent comporter des rétrécissements de section, de manière à pouvoir s'insérer facilement dans les extrémités correspondantes de la branche longitudinale 6b et du coude d'extrémité 7b du second élément 5b. L'assemblage du cadre tubulaire 2 est alors facilité et permet d'optimiser la rigidité de la planche 1 , car le cadre tubulaire 2 ne comporte que deux zones de soudure.The longitudinal branches 6a, 6b and the end bends 7a, 7b are assembled, for example, by welding, to ensure optimal rigidity in the tubular frame 2. Furthermore, the ends of the longitudinal branch 6a and the end bend 7a of the first element 5a may have section narrowing, so that it can be easily inserted into the corresponding ends of the longitudinal branch 6b and of the end bend 7b of the second element 5b. The assembly of the tubular frame 2 is then facilitated and makes it possible to optimize the rigidity of the board 1, since the tubular frame 2 only has two welding zones.
Comme représenté sur les figures 1 à 3, le cadre tubulaire 2, comporte, de préférence, deux platines de fixation 8, espacées entre elles selon une distance comparable à celle séparant les fixations d'un surf classique. Les platines de fixation 8, solidaires du cadre tubulaire 2, peuvent comporter des orifices 9, destinés à recevoir, par exemple, des fixations de surf traditionnelles (non représentées). Chaque platine de fixation 8 est réalisée dans une plaque plane, de préférence, en aluminium soudable, conformée selon la forme souhaitée. Chaque platine de fixation 8 comporte une surface plane de support 10, surélevée par rapport au cadre tubulaire 2 et comportant deux plis 11 sur ses bords, de manière à former deux ailes de fixation 12 sensiblement perpendiculaires à la surface plane 10 de support. Les ailes de fixation 12 sont rabattues à l'intérieur du cadre tubulaire 2 et sont destinées à recevoir les moyens de fixation de la platine 8 sur le cadre tubulaire 2. À titre d'exemple, les ailes de fixation 12 sont fixées par des rivets métalliques 13 sur le cadre tubulaire 2 (figure 1).As shown in FIGS. 1 to 3, the tubular frame 2 preferably includes two fixing plates 8, spaced apart at a distance comparable to that separating the bindings from a conventional board. The fixing plates 8, integral with the tubular frame 2, may include orifices 9, intended to receive, for example, traditional surfboard bindings (not shown). Each fixing plate 8 is produced in a flat plate, preferably made of weldable aluminum, shaped according to the desired shape. Each fixing plate 8 has a flat support surface 10, raised relative to the tubular frame 2 and comprising two folds 11 on its edges, so as to form two fixing wings 12 substantially perpendicular to the flat support surface 10. The fixing wings 12 are folded back inside the tubular frame 2 and are intended to receive the means for fixing the plate 8 on the tubular frame 2. For example, the fixing wings 12 are fixed by rivets 13 on the tubular frame 2 (Figure 1).
Comme représenté sur la figure 2, la surface plane 10 des platines de fixation 8 est orientée sensiblement horizontalement. L'angle d'orientation entre la surface plane 10 et l'horizontale peut varier selon les applications.As shown in Figure 2, the planar surface 10 of the fixing plates 8 is oriented substantially horizontally. The orientation angle between the flat surface 10 and the horizontal can vary depending on the applications.
Grâce à la surélévation des platines de fixation 8, la rigidité du cadre tubulaire 2 est assurée et tout contact est évité entre les platines de fixation 8 et le filet du trampoline, empêchant toute détérioration.Thanks to the elevation of the fixing plates 8, the rigidity of the tubular frame 2 is ensured and any contact is avoided between the fixing plates 8 and the trampoline net, preventing any deterioration.
Comme représenté sur la figure 1 , le cadre tubulaire 2 peut comporter un habillage central 14. L'habillage 14 est en matériau souple, de préférence un tissu du type grille d'aération textile, et peut aisément servir de support à une publicité ou à une simple décoration cousue ou collée. L'habillage 14 est conformé de telle sorte qu'il remplit complètement l'espace central délimité par le cadre tubulaire 2. L'habillage 14 est fixé sur les bords du cadre tubulaire 2 par des passants de retenue 15 (figure 1), solidaires de l'habillage 14 et entourant complètement le cadre tubulaire 2. Les passants 15 sont, de préférence, amovibles et repositionnables et sont, par exemple, en matière auto-agrippante textile ou plastique, sous forme de sangles de renfort. Le nombre des passants de retenue 15 est choisi afin d'assurer un maintien suffisant de l'habillage 1 4 sur le cadre tubulaire 2.As shown in FIG. 1, the tubular frame 2 can comprise a central covering 14. The covering 14 is made of flexible material, preferably a fabric of the textile ventilation grid type, and can easily serve as a support for an advertisement or a simple sewn or glued decoration. The covering 14 is shaped so that it completely fills the central space delimited by the tubular frame 2. The covering 14 is fixed to the edges of the tubular frame 2 by retaining loops 15 (FIG. 1), integral of the covering 14 and completely surrounding the tubular frame 2. The loops 15 are preferably removable and repositionable and are, for example, of self-gripping textile or plastic material, in the form of reinforcement straps. The number of passers-by retaining 15 is chosen to ensure sufficient retention of the covering 1 4 on the tubular frame 2.
L'habillage 14 peut donc servir de surface de sécurité ou tout simplement de surface de support à des fins esthétiques ou commerciales, particulièrement lors de manifestations de démonstration ou de promotion.The covering 14 can therefore serve as a safety surface or simply as a support surface for aesthetic or commercial purposes, particularly during demonstration or promotion events.
Dans la variante de réalisation de la planche de surf 1 représentée sur la figure 3, le cadre tubulaire 2 est équipé d'une chaussette d'habillage 16, entourant, de préférence, la majeure partie du cadre tubulaire 2, à l'exception des coudes d'extrémité 7a, 7b de la planche 1. La chaussette d'habillage 16 s'enfile par un des coudes d'extrémité 7a, 7b et comporte deux évidements 17 pour le passage des platines de fixation 8. Lorsque la chaussette 16 est enfilée, les platines de fixation 8 sont apparentes, grâce aux évidements 17, ce qui confère un aspect esthétique important.In the alternative embodiment of the surfboard 1 shown in FIG. 3, the tubular frame 2 is equipped with a covering sock 16, preferably surrounding the major part of the tubular frame 2, except for the end bends 7a, 7b of the board 1. The covering sock 16 is threaded through one of the end bends 7a, 7b and has two recesses 17 for the passage of the fixing plates 8. When the sock 16 is threaded, the fixing plates 8 are visible, thanks to the recesses 17, which gives an important aesthetic appearance.
La chaussette 16 est réalisée, de préférence, avec deux matériaux distincts. La partie supérieure de la chaussette 16, adjacente aux platines de fixation 8, est en matériau élastique de type stretch, par exemple du cordur, tandis que la partie inférieure de la chaussette 16, destinée à venir en contact avec le filet du trampoline, est en matériau textile du type tissu ajouré imprimable.The sock 16 is preferably made with two separate materials. The upper part of the sock 16, adjacent to the fixing plates 8, is made of elastic material of the stretch type, for example cordur, while the lower part of the sock 16, intended to come into contact with the trampoline net, is in textile material of the openwork printable fabric type.
La planche de surf 1 selon la présente invention présente non seulement une dimension ludique, mais s'avère aussi être un véritable outil pédagogique pour l'entraînement à la pratique sur neige et pour l'appréhension des contraintes qui en découlent. C'est pourquoi, la planche de surf 1 peut comporter des lests amovibles de différents poids (non représentés sur les figures 1 à 3 pour des raisons de clarté), afin de se rapprocher le plus possible des conditions réelles d'utilisation d'une planche de surf. Les lests peuvent être disposés de part et d'autre des pieds de l'utilisateur, entre une platine de fixation 8 et un coude d'extrémité 4, 7a, 7b correspondant. Les lests s'accrochent sur la cadre tubulaire 2, par exemple, par l'intermédiaire de crochets, qui viennent s'encliqueter autour du cadre tubulaire 2. Les lests peuvent représenter différentes charges et peuvent être combinés pour obtenir la masse désirée de la planche 1. Les lests amovibles permettent donc de configurer la planche 1 selon le poids et la taille de l'utilisateur et selon les applications recherchées.The surfboard 1 according to the present invention not only has a playful dimension, but also proves to be a real educational tool for training in the practice on snow and for understanding the constraints which result therefrom. This is why the surfboard 1 may include removable weights of different weights (not shown in FIGS. 1 to 3 for reasons of clarity), in order to get as close as possible to the actual conditions of use of a surfboard. The weights can be arranged on either side of the feet of the user, between a fixing plate 8 and an end bend 4, 7a, 7b corresponding. The weights hang on the tubular frame 2, for example, by means of hooks, which snap around the tubular frame 2. The weights can represent different loads and can be combined to obtain the desired mass of the board 1. The removable weights therefore make it possible to configure the board 1 according to the weight and size of the user and according to the desired applications.
L'invention n'est pas limitée aux différents modes de réalisation décrits ci- dessus. Les platines de fixation 8 peuvent être fixées, notamment, sur le cadre tubulaire 2. Les ailes de fixation 12 perpendiculaires à la surface de support 10 des platines de fixation 8 sont alors soudées sur le dessus du cadre tubulaire 2. Une telle configuration permet de renforcer la rigidité de la planche 1 , les platines de fixation 8 s'appuyant sur l'épaisseur du cadre tubulaire 2.The invention is not limited to the various embodiments described above. The fixing plates 8 can be fixed, in particular, to the tubular frame 2. The fixing wings 12 perpendicular to the support surface 10 of the fixing plates 8 are then welded to the top of the tubular frame 2. Such a configuration makes it possible to reinforce the rigidity of the board 1, the fixing plates 8 resting on the thickness of the tubular frame 2.
Les platines de fixation 8 peuvent être en matériau aimanté. Ainsi, les platines de fixation 8 ne comportent pas d'orifices et coopèrent avec des chaussures à semelle aimantée. Une telle configuration évite l'encombrement engendré par les fixations de surf traditionnelles et permet à n'importe quel utilisateur d'utiliser la planche 1.The fixing plates 8 can be made of magnetic material. Thus, the fixing plates 8 do not have orifices and cooperate with shoes with a magnetic sole. Such a configuration avoids the bulk created by traditional surfboard bindings and allows any user to use the board 1.
Les platines de fixation 8 peuvent être reliées par leur surface plane 10, pour ne former qu'une seule platine de fixation solidaire du cadre tubulaire 2.The fixing plates 8 can be connected by their flat surface 10, so as to form a single fixing plate secured to the tubular frame 2.
Les orifices 9 des platines de fixation 8 sont adaptables à tout moyen de fixation des pieds d'un utilisateur sur la planche 1. Les lests peuvent se positionner sous les platines de fixation 8, par l'intermédiaire, par exemple, de petites ornières réalisées dans les ailes de fixation 12 des platines de fixation 8. Les lests ont, par exemple, la forme d'un disque et viennent se glisser dans les ornières.The orifices 9 of the fixing plates 8 are adaptable to any means of fixing the feet of a user on the board 1. The weights can be positioned under the fixing plates 8, by means, for example, of small ruts made in the fixing wings 12 of the fixing plates 8. The weights have, for example, the shape of a disc and come to slip into the ruts.
Une telle planche de surf 1 pour sauts sur trampoline est donc très maniable, légère, n'abîme pas le trampoline et peut être utilisée pour la pratique de tous les sports de planche, à savoir snowboard, kitesurf, wakeboard, etc. Such a surfboard 1 for jumping on a trampoline is therefore very handy, light, does not damage the trampoline and can be used for the practice of all board sports, namely snowboarding, kitesurfing, wakeboarding, etc.
