Description

TREMPLIN DE GYMNASTIQUE A ÉLASTICITÉ RÉGLABLE GYMNASTIC SPRINGBOARD WITH ADJUSTABLE ELASTICITY
La présente invention a pour objet un tremplin de gymnas tique à élasticité réglable.The present invention relates to a springboard gymnastics tick with adjustable elasticity.
II est destiné à l'équipement des salles ou des terrain de sport et peut être utilisé aussi bien pour l'entraînement que pou la compétition.It is intended for equipping halls or sports grounds and can be used both for training and for competition.
Les tremplins actuels servant à la compétition, homologué par la Fédération Internationale de Gymnastique (F.I.G.) ont des ca ractéristiques bien définies, à savoir longueur 1200 mm, largeur 60 mm, hauteur 220 mm, avec une élasticité constante, identique pour un jeune gymnaste de 30 kgs ou pour un garçon de 80 kgs.The current springboards used for competition, approved by the International Gymnastics Federation (FIG) have well defined characteristics, namely length 1200 mm, width 60 mm, height 220 mm, with constant elasticity, identical for a young gymnast of 30 kgs or for a boy of 80 kgs.
Le tremplin en gymnastique artistique sert, après un course d'environ 25 mètres, à prendre appel avec les deux pieds afi de franchir un obstacle, à savoir le cheval de saut.The springboard in artistic gymnastics is used, after a race of about 25 meters, to take up with both feet in order to overcome an obstacle, namely the jumping horse.
Les exercices au cheval de saut ont considérablement évo lué, de nouveaux sauts sont apparus: par exemple, au lieu de saute face à l'obstacle, les gymnastes effectuent en fin de course un demi tour sur eux-mêmes après avoir posé les mains au sol et se .retrouven les deux pieds sur le tremplin, le dos au cheval, pour réaliser u saut par renversement arrière.The exercises on the jumping horse have evolved considerably, new jumps have appeared: for example, instead of jumping in front of the obstacle, the gymnasts perform at the end of the race a half turn on themselves after having put their hands to the ground and .rouven two feet on the springboard, back to the horse, to perform a jump by reverse inversion.
On conçoit aisément la grande difficulté à ne pas manque le tremplin, car avant la pose des pieds il y a une perte visuell momentanée du tremplin. Malheureusement, l'utilisation des tremplin actuels a déjà entraîné des accidents très graves, voire mortels.It is easy to see the great difficulty in not missing the springboard, because before the feet are placed there is a temporary visual loss of the springboard. Unfortunately, the use of the current springboard has already led to very serious and even fatal accidents.
Le dispositif selon la présente invention a pour but d réduire considérablement ces risques tout en augmentant l'efficacit du tremplin, sa visualisation et ses caractéristiques d'élasticit puisqu'elles seront réglées par le gymnaste en fonction du saut a ef fectuer et de sa morphologie (fille ou garçon).The device according to the present invention aims to considerably reduce these risks while increasing the effectiveness of the springboard, its visualization and its elasticity characteristics since they will be adjusted by the gymnast according to the jump to ef perform and its morphology (girl or boy).
Il est constitué par la combinaison, d'une part, d'un plateau souple plus grand que les plateaux homologués, mais comportant une zone de couleur différente ayant les dimensions réglementaires, ce plateau étant constitué d'une partie courbée à l'arrière et d'une par¬ tie plane à l'avant, et ayant son extrémité arrière articulée par une charnière à un châssis et son extrémité avant reliée au même châssis par l'intermédiaire de ressorts, d'autre part, d'un chariot coulissant longitudinalement sous la partie plane dudit plateau et portant des ressorts sur lesquels appuie le plateau lors des sauts et permettant d'ajuster l'élasticité de ce dernier en modifiant leur position, le tremplin pouvant être équipé de moteurs électriques commandant le dé¬ placement du chariot et du tremplin lui-même.It consists of the combination, on the one hand, of a flexible plate larger than the approved plates, but comprising a different colored zone having the statutory dimensions, this plate consisting of a curved part at the rear and of a flat part at the front, and having its rear end articulated by a hinge to a chassis and its front end connected to the same chassis by means of springs, on the other hand, of a carriage sliding longitudinally under the flat part of said plate and carrying springs on which the plate rests during jumps and making it possible to adjust the elasticity of the latter by modifying their position, the springboard can be equipped with electric motors controlling the movement of the carriage and of the springboard itself.
Sur les dessins annexés, donnés à titre d'exemple non li¬ mitatif d'une des formes de réalisation de' l'objet de l'invention: la figure 1 représente une vue latérale du tremplin mon¬ trant le plateau souple, le châssis, l'articulation par charnière, les ressorts boulonnés sur le plateau souple et sur le châssis au point, la figure 2 représente le tremplin en perspective, et montre en particulier la partie de couleur différente de dimensions conformes aux normes de la F.I.G', la figure 3 montre le tremplin en perspective, sans le plateau souple de dessus, afin de voir le mécanisme du chariot qui est représenté en position extrême, tout à l'avant du châssis, position donnant le maximum de souplesse au tremplin,In the accompanying drawings, given by way of non-li¬ mitatif example of one of the embodiments of 'the subject of the invention: Figure 1 shows a side view of the springboard mon¬ trating the flexible plate, the chassis , the articulation by hinge, the springs bolted on the flexible plate and on the chassis in point, Figure 2 represents the springboard in perspective, and shows in particular the part of different color of dimensions in accordance with the standards of FIG ', FIG. 3 shows the springboard in perspective, without the flexible top plate, in order to see the mechanism of the carriage which is shown in the extreme position, all at the front of the chassis, position giving the maximum flexibility to the springboard,
La figure 4 est une vue en perspective du tremplin sans le plateau souple, permettant de voir les mécanismes de deux moteurs de déplacement du chariot et du tremplin, le chariot se trouvant en po¬ sition arrière extrême ce qui a pour effet de rendre le tremplin très dur.Figure 4 is a perspective view of the springboard without the flexible plate, allowing to see the mechanisms of two motors for moving the carriage and the springboard, the carriage being in extreme rear po¬ sition which has the effect of making the springboard very difficult.
Le plateau souple 1, 2 a des dimensions nettement plus grandes que la norme en vigueur mais, comme le montre la figure 2, la surface de réception 8 aux dimensions actuellement normalisées, est d'une couleur nettement différente de celle de la partie l'entourant sur les côtés et à l'avant et formant une zone de sécurité 9 ayant toutefois les mêmes caractéristiques d'élasticité que la partie 8 de façon à ce que si un gymnaste venait frapper la zone 9, il franchirait tout de même le cheval de saut sans risque. Dans le cas ou les normes changeraient, la surface 8 pourrait être modifiée en conséquence.The flexible plate 1, 2 has dimensions considerably larger than the standard in force, but, as shown in FIG. 2, the receiving surface 8 with the dimensions currently standardized, is of a color distinctly different from that of the part surrounding it on the sides and at the front and forming a safety zone 9 having however the same elasticity characteristics as part 8 so that if a gymnast came hitting zone 9, he would still cross the jumping horse without risk. In the event that the standards change, the surface 8 could be modified accordingly.
La partie 8 peut éventuellement être légèrement surélevée par rapport à la partie 9, ceci afin d'augmenter la visualisation. Dans ce cas, ses bords se marieront en pente douce avec la surface 9. La zone de sécurité 9 pourra comporter un tapis magnétique permettant un contact électrique afin de déclencher un signal sonore ou visuel lorsque le gymnaste sautera sur cette zone non homologuée.Part 8 can possibly be slightly raised relative to part 9, this in order to increase the visualization. In this case, its edges will marry in a gentle slope with the surface 9. The safety zone 9 may include a magnetic mat allowing electrical contact in order to trigger an audible or visual signal when the gymnast jumps onto this unauthorized zone.
Le plateau souple 1, 2, recouvert de mousse et de moquet¬ te, peut être en matériau composite, par exemple fibre de verre car— bonne, "Quevlar" avec balza ou nid d'abeille, en aluminium ou tout simplement en bois tel que ultiplis hêtre ou autre. Il est constitué à l'arrière d'une partie courbée 1 à concavité dirigée vers" le bas et à l'avant d'une partie plane et horizontale 2.The flexible tray 1, 2, covered with foam and moquet¬ te, can be made of composite material, for example fiberglass car— good, "Quevlar" with balza or honeycomb, aluminum or simply wooden such than ultiplis beech or other. It is made in the back of a curved portion 1 with concavity directed toward the "bottom to the front of a plane and horizontal portion 2.
L'extrémité arrière de la partie courbée 1 (partie basse du tremplin) est fixée par des charnières 4 permettant une parfaite mobilité du plateau souple, à un châssis 3 qui recevra tous les orga¬ nes mécaniques. L'extrémité avant de la partie plane 2 (partie haute) est reliée au châssis 3 par deux ressorts fixes 5 et 5' (ou tout autre organe souple ayant les mêmes caractéristiques) boulonnés sur le pla¬ teau souple au point 6 et sur le châssis au point 7.The rear end of the curved part 1 (lower part of the springboard) is fixed by hinges 4 allowing perfect mobility of the flexible plate, to a chassis 3 which will receive all the mechanical organs. The front end of the flat part 2 (upper part) is connected to the chassis 3 by two fixed springs 5 and 5 '(or any other flexible member having the same characteristics) bolted to the flexible plate at point 6 and on the chassis at point 7.
Le châssis 3 pourra être en n'importe quel matériau plat et rigide: métal, plastique, bois, contreplaqué. Le dessous sera équipé d'antidérapant. Deux autres ressorts 13 et 13' à spires (qui pourraient évidemment être remplacés par d'autres éléments élastiques donnant des résultats similaires tels que mousses, ressorts à lames, etc) sont fixés sur un chariot A, lui-même coulissant sur un rail 16 fixé sur le châssis permettant des déplacements des deux ressorts sous la partie plate 2 du plateau souple, sans pour autant la toucher, un millimètre environ d'espace libre étant laissé pour ne pas freiner le déplacement. du chariot A. Ces deux ressorts 13 et 13' sont reliés à une planche 1 (en bois ou autre matériau) pour une bonne tenue mécanique, planch sur laquelle il y aura un caoutchouc ou de la moquette pour éviter l bruit lors des sauts.The frame 3 can be made of any flat and rigid material: metal, plastic, wood, plywood. The underside will be equipped with non-slip. Two other springs 13 and 13 'with turns (which could obviously be replaced by other elastic elements giving similar results such as foams, leaf springs, etc.) are fixed on a carriage A, itself sliding on a rail 16 fixed on the chassis allowing displacements of the two springs under the flat part 2 of the flexible plate, without however touching it, approximately one millimeter of free space being left so as not to slow down the displacement. of the carriage A. These two springs 13 and 13 ′ are connected to a board 1 (made of wood or other material) for good mechanical strength, a board on which there will be a rubber or carpet to avoid noise during jumps.
Le chariot A se compose d'une glissière 10, d'une chape 1 d'un levier de crantage 12 permettant de manoeuvrer le chariot, d support des deux ressorts 13 et 13' et d'un renfort 15. Le rail 16 es solidaire du châssis 3 par l'intermédiaire de cales ou entretoises permettant à la glissière de coulisser sur le rail et fixées par les vis 17 et 17' , les autres trous servant au crantage du chariot ce qui évitera aux ressorts de se déplacer lors de sauts violents.The carriage A is made up of a slide 10, of a yoke 1 of a notching lever 12 making it possible to maneuver the carriage, of support for the two springs 13 and 13 ′ and of a reinforcement 15. The rail 16 is integral of the chassis 3 by means of wedges or spacers allowing the slide to slide on the rail and fixed by the screws 17 and 17 ', the other holes serving for the notching of the carriage which will prevent the springs from moving during violent jumps .
Le déplacement du chariot A s'effectue par une seule opé¬ ration manuelle (ou du pied) du levier 12, assurant le débloquage et le déplacement du chariot en avant ou en arrière.The movement of the carriage A is carried out by a single manual operation (or of the foot) of the lever 12, ensuring the unlocking and the movement of the carriage forward or backward.
On comprend aisément que lorsque le chariot A se trouve du côté des ressorts fixes 5, 5'(figure 3), à l'avant du plateau souple, le tremplin est en position très souple et, à l'inverse, lorsque le chariot se trouve au début de la partie courbée 1 du plateau souple, le tremplin est en position très dure (figure 4).It is easily understood that when the carriage A is on the side of the fixed springs 5, 5 '(FIG. 3), at the front of the flexible plate, the springboard is in the very flexible position and, conversely, when the carriage found at the start of the curved part 1 of the flexible platform, the springboard is in a very hard position (Figure 4).
Il faut savoir également que la distance du tremplin au cheval de saut se règle en fonction du saut à effectuer, donc le gym¬ naste doit régler, avant de sauter, la distance du tremplin au cheval de saut et son élasticité. Souvent il se trouve en bout des 25 mètres et doit revenir pour voir si un autre gymnaste ne l'a pas touché ou déréglé.You should also know that the distance from the springboard to the jumping horse is adjusted according to the jump to be made, so the gymnast must adjust, before jumping, the distance from the springboard to the jumping horse and its elasticity. Often he is at the end of 25 meters and must come back to see if another gymnast has not touched or disturbed him.
Afin de simplifier ces tâches, l'invention permet égale¬ ment l'utilisation de deux moteurs situés soit à côté, soit devant le tremplin, commandés par système électrique ou télécommandés. Ces sys¬ tèmes de commande des moteurs seront doublés, deux à côté du tremplin, deux à 25 mètres (point de départ du gymnaste) et auront des afficha¬ ges digitaux ou à cristaux liquides ou tout autre moyen d'indication numérique. Donc le gymnaste pourra, avant de sauter, voir les deu>: paramètres, distance et élasticité, et pourra également les modifier grâce à un simple clavier numérique type calculette, ces manipulations pouvant se faire aussi bien en étant à côté du tremplin qu'en étant au bout de la piste de saut.In order to simplify these tasks, the invention also allows the use of two motors located either next to or in front of the springboard, controlled by electric system or remote-controlled. These engine control systems will be doubled, two next to the springboard, two 25 meters (starting point of the gymnast) and will have digital or liquid crystal displays or any other means of digital indication. So the gymnast will be able, before jumping, to see the two: parameters, distance and elasticity, and will also be able to modify them thanks to a simple numerical keyboard like calculator, these manipulations can be done as well by being next to the springboard as being at the end of the jump track.
Sur la figure 4 le tremplin est représenté sans le plateau souple, afin de mieux voir les mécanismes des deux moteurs. Le moteur 18, fixé sur le châssis 3, entraîne une vis sans fin 19, elle-même fixée au châssis par l'intermédiaire d'un palier 20 et ayant pour effet, suivant la commande du moteur (rotation à droite ou à gauche) par l'intermédiaire de l'écrou 21, de provoquer des dé¬ placements avant ou arrière du chariot A, tout autant que la vis 22 permet la solidarisation du levier de crantage 12 sur l'écrou 21, en position bien évidemment décrantée. On pourra enlever la vis rapide 22 (ou goupille rapide) en cas de panne électrique pour rétablir un réglage manuel avec le levier de crantage 12. Les graduations 23 per¬ mettent de situer le degré d'élasticité du tremplin. Le moteur 29, fixé sur un socle non représenté sur le dessin, comportant des rails pour guider le déplacement du tremplin, actionne une vis sans fin 24 fixée sur ledit socle par l'intermédiaire d'un palier 25 et ayant pour effet suivant la commande du moteur (ro¬ tation à droite ou à gauche) par l'intermédiaire de l'écrou 26, de provoquer des déplacements avant ou arrière du tremplin tout autant que la vis 27 sera solidaire du châssis 3. La désolidarisation de la vis rapide 27 permet de revenir à un réglage manuel en cas de panne électrique. Les graduations 28 positionnées sur ledit socle permettent de situer la distance du tremplin par rapport au cheval. Les commandes électriques, électromécaniques et électro¬ niques ne sont pas décrites, s'agissant de matériel conventionnel commercialisé.In Figure 4 the springboard is shown without the flexible plate, to better see the mechanisms of the two motors. The motor 18, fixed to the chassis 3, drives an endless screw 19, itself fixed to the chassis by means of a bearing 20 and having the effect, depending on the control of the motor (rotation to the right or to the left) by means of the nut 21, to cause the front or rear displacements of the carriage A, just as much as the screw 22 allows the locking lever 12 to be secured to the nut 21, in the obviously stripped position. We can remove the quick screw 22 (or quick pin) in case of power failure to restore manual adjustment with the notch lever 12. The graduations 23 per¬ put to locate the degree of springboard. The motor 29, fixed on a base not shown in the drawing, comprising rails to guide the movement of the springboard, actuates an endless screw 24 fixed on said base via a bearing 25 and having the following effect on the command of the motor (rotation to the right or to the left) via the nut 26, to cause front or rear displacements of the springboard just as much as the screw 27 will be secured to the chassis 3. The separation of the rapid screw 27 returns to manual adjustment in the event of a power failure. The graduations 28 positioned on said base make it possible to locate the distance of the springboard relative to the horse. The electrical, electromechanical and electronic controls are not described, being conventional equipment sold.
Le positionnement des divers éléments constitutifs donne à l'objet de l'invention un maximum d'effets utiles qui n'avaient pas été, à ce jour, obtenus par des dispositifs similaires. The positioning of the various constituent elements gives the object of the invention a maximum of useful effects which had not, to date, been obtained by similar devices.
