SKI A VOILE SAILING SKI
Mémoire descriptifDescriptive memory
La présente invention se rapporte à un cerf-volant pour faire de la voile.The present invention relates to a kite for sailing.
Pour faire de la voile avec un cerf-volant, il faut pouvoir le diriger pour le faire voler près du sol dans la direction où l'on veut aller. Plus il vole bas, plus on va vite et ce faisant, il peut toucher le sol et s'effondrer. J'ai découvert qu'en utilisant un cerf-volant compact de style parapente, il pouvait glisser sur la neige ou l'eau sans s'effondrer. Il suffit que le parapente soit de forme compacte et lorsqu'il touche le sol, il n'a pas tendance à pivoter.To sail with a kite, you have to be able to steer it to make it fly close to the ground in the direction you want to go. The lower it flies, the faster it goes and in doing so, it can hit the ground and collapse. I discovered that by using a compact paraglider-style kite, it could slide on snow or water without collapsing. It is enough that the paraglider is compact in shape and when it touches the ground, it does not tend to pivot.
Mais ce genre de cerf-volant possède de longues cordes qui servent à le tenir et à le diriger. Celles-ci peuvent s'emmêler lorsque l'on rate une manoeuvre et il faut du temps et de la technique pour repartir. J'ai découvert que l'on pouvait utiliser un support formé de deux tubes joints ensemble de façon rigide en forme de " T " auxquels on fixe les cordes et qui permet à la fois de réduire considérablement leur longueur de façon à ce qu'elles ne puissent plus s'emmêler et à la fois d'agir en rotation sur la voile de sorte qu'on n'a pas besoin d'actionner les cordes elles-mêmes, ce qui facilite grandement la manoeuvre.But this kind of kite has long strings that are used to hold and steer it. These can get tangled when you miss a maneuver and it takes time and technique to start again. I discovered that one could use a support formed of two tubes joined together rigidly in the shape of a "T" to which the strings are fixed and which allows both to considerably reduce their length so that they can no longer get tangled and at the same time act in rotation on the sail so that there is no need to actuate the ropes themselves, which greatly facilitates the maneuver.
SUBSmUTE SHEET (RULE 26)
Un parapente tient sa stabilité de son allongement, mais j'ai découvert qu'il suffisait de deux pièces de toile triangulaires reliées en " V " par deux cordes à l'arrière du support en " T " pour donner la stabilité voulue à un parapente compact.SUBSmUTE SHEET (RULE 26) A paraglider keeps its stability from its elongation, but I discovered that it was enough of two triangular pieces of canvas connected in "V" by two cords at the back of the support in "T" to give the desired stability to a paraglider compact.
Lorsqu'on tombe, il faut que le joint en " T " entre les deux tubes puisse pivoter pour ne pas briser, mais il faut aussi qu'il soit suffisamment rigide pour ne pas pivoter lorsqu'on a besoin de contrôler la voile en rotation. J'ai découvert qu'il suffisait de fixer sur le bout avant du tube arrière une section semi-cylindrique qui vient s'emboîter sur le tube avant et qui y est tenue par un élastique. Quand le joint force, il se déboîte en soulevant l'élastique puis se remet en place tout seul.When falling, the "T" joint between the two tubes must be able to pivot so as not to break, but it must also be rigid enough not to pivot when it is necessary to control the sail in rotation. . I discovered that it was enough to fix on the front end of the rear tube a semi-cylindrical section which comes to fit on the front tube and which is held there by an elastic band. When the seal forces, it dislodges by lifting the elastic then replaces itself.
J'ai découvert que l'on pouvait réduire considérablement le nombre et la grandeur des ouvertures qui permettent à la voile de gonfler. Il faut plus de temps pour l'établir mais la pression interne est aussi bonne. Cela donne une meilleure forme à la voile, réduit le temps de fabrication, et permet de l'utiliser sur l'eau.I discovered that you could greatly reduce the number and size of the openings that allow the sail to inflate. It takes longer to establish it but the internal pressure is also good. This gives a better shape to the sail, reduces the manufacturing time, and allows it to be used on water.
Pour l'utiliser sur l'eau, j'ai découvert qu'il suffisait de coincer dans les ouvertures des blocs de " foam " hydrofuge munis d'une rainure pour y coincer la toile, et percés d'une cheminée pour laisser pénétrer l'air. Lorsque la voile tombe sur l'eau du côté des ouvertures, l'eau ne peut pas remonter les cheminées et pénétrer dans la voile.
J'ai découvert que l'on pouvait enlever ou ajouter facilement une section de deux cellules à la voile en ajoutant un zipper au centre. On peut réduire ou augmenter la surface de voilure de 25% et avoir une seule voile pour tout l'échantillonnage des vents.To use it on water, I discovered that it was enough to wedge in the openings blocks of water-repellent "foam" provided with a groove to wedge the canvas there, and pierced with a chimney to let penetrate the 'air. When the sail falls on the water on the side of the openings, the water cannot go up the chimneys and enter the sail. I discovered that you could easily remove or add a section of two cells to the sail by adding a zipper in the center. We can reduce or increase the sail area by 25% and have only one sail for all wind sampling.
J'ai découvert que l'on pouvait utiliser du polyéthylène tissé très mince (3.2 on/vg2) pour le revêtement extérieur de la voile qui ne supporte que la pression d'air. Cette partie de la voile nécessite une toile de moindre résistance que les sections où s'attachent les cordes. Cette toile est suffisamment légère pour le ski à voile car il faut un vent minimum de 15 km/hre pour avancer sur la neige. Par contre, elle est 7 fois moins dispendieuse que celle utilisée actuellement pour les parapentes. Comme elle est étanche à 100%, on peut réduire les ouvertures à presque rien tout en conservant la même pression d'air dans la voile. Pour les sections internes, on peut utiliser du polyéthylène plus lourd (plus résistant) ou du nylon léger.I discovered that you could use very thin woven polyethylene (3.2 oz / yd2) for the outer covering of the sail, which only supports air pressure. This part of the sail requires a canvas of less resistance than the sections where the ropes are attached. This canvas is light enough for ski sailing because it takes a minimum wind of 15 km / hr to advance on the snow. On the other hand, it is 7 times less expensive than that currently used for paragliders. As it is 100% waterproof, the openings can be reduced to almost nothing while maintaining the same air pressure in the sail. For internal sections, heavier (more resistant) polyethylene or light nylon can be used.
