La présente invention concerne un dispositif réservé à l'initiation, l'entraînement ou le perfectionnement, d'un skieur nautique. The present invention relates to a device reserved for initiation, training or improvement, of a water skier.
La pratique du ski nautique, traditionnellement, nécessite un bateau à moteur avec pilote et observateur, un plan d'eau calme de grande dimension, ainsi que des conditions météorologiques propices, obligeant les adeptes de ce sport à une pratique saisonnière, tout au moins dans les régions de la planète o les périodes froides sont longues et rigoureuses. The practice of water skiing, traditionally, requires a motor boat with pilot and observer, a large body of calm water, as well as favorable weather conditions, obliging the followers of this sport to a seasonal practice, at least in regions of the planet where cold periods are long and severe.
L'équipage, pilote, observateur, skieur, quitte le ponton, et évolue loin de la berge, loin des spectateurs. The crew, pilot, observer, skier, leaves the pontoon, and moves away from the shore, away from the spectators.
L'apprentissage du ski, est difficile, le débutant chute souvent; le bateau doit alors s'arrêter et faire demi-tour pour repêcher le skieur. Learning to ski is difficult, the beginner often falls; the boat must then stop and turn around to rescue the skier.
L'entraînement à la discipline des figures est très fastidieux, tant pour le moniteur, que pour l'élève car les chutes sont très fréquentes. Training in the discipline of figures is very tedious, both for the instructor and for the student because falls are very frequent.
Le skieur nautique doit s'armer de patience car il passe beaucoup de 15 temps sur le ponton à attendre son tour. The water skier must be patient because he spends a lot of time on the pontoon waiting for his turn.
La communication entre le moniteur et l'élève est difficile à cause de la distance qui les sépare, et du bruit du moteur, obligeant ceux ci à communiquer par gestes. Communication between the instructor and the student is difficult because of the distance between them, and the noise of the engine, forcing them to communicate by gestures.
Les adeptes du ski nautique sont mal vus par les pêcheurs, les 20 écologistes, car les bateaux, font du bruit, des vagues, et polluent. Water skiing enthusiasts are frowned upon by fishermen, the 20 environmentalists, because the boats make noise, waves, and pollute.
Ce sport n'est pas à la portée de tout un chacun, car il est coûteux. This sport is not accessible to everyone because it is expensive.
Le dispositif selon l'invention permet de remédier à tous ces inconvénients, car il peut s'inscrire, dans sa forme essentielle, dans un espace restreint de la grandeur d'une piscine. The device according to the invention makes it possible to remedy all of these drawbacks, because it can be inscribed, in its essential form, in a restricted space the size of a swimming pool.
Le principe du ski nautique, consiste à tracter le skieur à l'aide du mat de traction fixé sur le bateau, de la corde et du palonnier de façon à ce que sa vitesse de déplacement lui permette d'obtenir une portance sur l'eau. The principle of water skiing is to tow the skier using the traction mat fixed on the boat, the rope and the spreader so that its speed of movement allows it to obtain a lift on the water. .
Le principe de l'invention consiste à amarrer l'ensemble corde palonnier à un mat scellé sur le bord d'un bassin, retenant ainsi le skieur, et à faire 30 défiler sous ses pieds un courant d'eau, à l'aide de turbines placées sous le bord de ce même bassin. The principle of the invention consists in mooring the lifter rope assembly to a sealed mast on the edge of a pool, thus retaining the skier, and making a stream of water pass under his feet, using turbines placed under the edge of this same basin.
L'eau propulsée revient vers les turbines par un conduit périphérique, utilisant la même quantité d'eau en circuit fermé. The propelled water returns to the turbines through a peripheral duct, using the same amount of water in a closed circuit.
Le skieur a une vitesse de déplacement nulle par rapport à son environnement, mais peut se déplacer latéralement de façon pendulaire avec des accélérations qui lui permettent grâce au mou de corde, d'exécuter des virages ainsi que des figures. The skier has a zero displacement speed compared to his environment, but can move laterally in a pendulum with accelerations which allow him, thanks to the slack of the rope, to execute turns as well as figures.
Les dessins annexés illustrent l'invention: La figure 1 représente en coupe le dispositif de l'invention. 40 La figure 2 représente en plan le dispositif de l'invention. The accompanying drawings illustrate the invention: Figure 1 shows in section the device of the invention. Figure 2 shows in plan the device of the invention.
En référence à ces dessins, le dispositif comporte un bassin (1) un conduit périphérique recouvert (2) permettant à l'eau propulsée par les turbines (3) de revenir indéfiniment dans le bassin (1) par le conduit en circuit fermé (2). With reference to these drawings, the device comprises a basin (1) a covered peripheral conduit (2) allowing the water propelled by the turbines (3) to return indefinitely into the basin (1) by the conduit in closed circuit (2 ).
Sur le bord du bassin (1) est scellé un mat de retenue (4) auquel sont fixés la corde (5) et le palonnier (6). On the edge of the basin (1) is sealed a retaining mat (4) to which are fixed the rope (5) and the lifter (6).
Sur le bord du bassin (1) est installé un moteur électrique (7) d'o part un arbre de transmission (8) qui fait tourner les turbines (3) disposées en série. On the edge of the basin (1) is installed an electric motor (7) from where a transmission shaft (8) which rotates the turbines (3) arranged in series.
Le moteur électrique (7) caréné, est muni d'un tableau de commande avec potentiomètre, o s'installe le pilote du dispositif. The faired electric motor (7) is fitted with a control panel with potentiometer, where the device driver is installed.
Cela n'empêche pas de disposer dans le palonnier (6) du skieur (11) un bouton à impulsions, relié au potentiomètre par un émetteur radio, qui lui permet de régler lui-même la vitesse de propulsion de l'eau selon son poids, la dimension de son ou de ses skis ou bien des figures qu'il désire exécuter. This does not prevent having a pulse button in the lifter (6) of the skier (11), connected to the potentiometer by a radio transmitter, which allows it to adjust the propulsion speed of the water itself according to its weight. , the size of his or his skis or the figures he wishes to perform
En cas de chute du skieur (11), si celui-ci a lâché le palonnier (6), un 15 coupe circuit stoppe automatiquement par sécurité, la propulsion de l'eau. In the event of the skier (11) falling, if the skier has released the lifter (6), a circuit breaker automatically stops the propulsion of water for safety.
A l'endroit o l'eau s'échappe du bassin (1) pour être conduite dans le circuit périphérique (2) on dispose une grille de sécurité (9) en pente douce pour éviter tout accident. At the place where water escapes from the basin (1) to be conducted in the peripheral circuit (2) there is a safety grid (9) gently sloping to avoid any accident.
Pour reproduire artificiellement le sillage du bateau dont le skieur (l1) nautique se sert pour exécuter des sauts de vague ou des figures décollées, on immerge un aileron amovible (10) devant chacune des turbines (3) situées de part et d'autre de l'axe central pour provoquer deux remous qui font effet de vagues sur lesquelles le skieur (11) peut effectuer des figures décollées. To artificially reproduce the wake of the boat which the nautical skier (11) uses to perform wave jumps or unstuck figures, a removable fin (10) is immersed in front of each of the turbines (3) located on either side of the central axis to cause two eddies which have the effect of waves on which the skier (11) can perform detached figures.
Les dessins annexés illustrent des variantes de l'invention: La figure 3 représente en coupe une variante du dispositif de l'invention l'eau propulsée en surface revient vers les turbines (3) par un conduit souterrain (2) en circuit fermé, comme dans le principe du tapis roulant. The accompanying drawings illustrate variants of the invention: FIG. 3 shows in section a variant of the device of the invention the water propelled on the surface returns to the turbines (3) by an underground conduit (2) in closed circuit, as in principle of the treadmill.
La figure 4 représente en coupe le dispositif de l'invention avec le système de circulation d'eau périphérique (2) mais adapté sur un bassin (1) plus profond, 30 avec grand et petit bain, qui sert de piscine lorsque les turbines (3) ne sont pas en action. FIG. 4 represents in section the device of the invention with the peripheral water circulation system (2) but adapted on a deeper basin (1), with large and small bath, which serves as a swimming pool when the turbines ( 3) are not in action.
Ou: si les turbines (3) sont actionnées à très faible régime permettre la natation à contre courant. Or: if the turbines (3) are operated at very low speed, allow swimming against the current.
Et: à un régime moyen, permettre à un baigneur qui se retient au palonnier 35 (6) le corps immergé, d'être massé par le courant d'eau et ainsi pratiquer l'hydrothérapie. And: at an average speed, allow a bather who retains the immersed body at the lifter 35 (6), to be massaged by the stream of water and thus practice hydrotherapy.
A titre d'exemple non limitatif le bassin s'inscrira dans un espace de mètres sur 30 mètres. By way of nonlimiting example, the basin will be in a space of meters by 30 meters.
Ce bassin dans ces dimensions est propice à l'initiation au ski nautique 40 d'enfants et adultes, à l'entraînement à la discipline des figures, ainsi qu'au - 3 perfectionnement en figures de compétiteurs de haut niveau. This pool in these dimensions is conducive to initiation to water skiing 40 for children and adults, training in the discipline of figures, as well as - 3 improvement in figures of high level competitors.
Si l'on veut à l'aide de ce même principe d'invention permettre l'exécution des deux autres disciplines du ski nautique; c'est à dire le slalom et le saut il faut concevoir un bassin de dimension beaucoup plus importante. If we want to use this same principle of invention to allow the execution of the other two disciplines of water skiing; that is to say the slalom and the jump it is necessary to conceive a basin of much larger dimension.
La figure 5 représente le dispositif selon le même principe d'invention, installé sur la rive d'un lac (1), avec un nombre de turbines (3) non limité, propulsant l'eau dans le lac (1) o elle se perd, deux larges bouches(12) reliées entre elles par un canal qui passe derrière les turbines (3), chacune d'entre elles est placée de chaque côté du dispositif l'eau est ainsi aspirée par 10 les turbines (3) et propulsée vers le skieur (11) Une grille de sécurité (9) est placée à l'entrée de chacune des bouches (12). - 4 Figure 5 shows the device according to the same principle of invention, installed on the shore of a lake (1), with an unlimited number of turbines (3), propelling water into the lake (1) where it loses, two large mouths (12) connected together by a channel which passes behind the turbines (3), each of them is placed on each side of the device, the water is thus sucked in by the turbines (3) and propelled towards the skier (11) A safety grid (9) is placed at the entrance to each of the vents (12). - 4
