Description

ENGIN NAUTIQUE PROPULSÉ ET DIRIGÉ PAR L'UTILISATEUR DEBOUT, SANS L'AIDE DES MAINS BOAT MACHINE POWERED AND DIRECTED BY THE STANDING USER, WITHOUT THE HELP OF HANDS
Cette invention concerne un engin nautique propulsé et dirigé par l'utilisateur debout sans l'aide des mains.This invention relates to a nautical device propelled and directed by the standing user without the help of the hands.
Sur les engins existants la transmission des mouvements des utilisateurs aux propulseurs nécessite une certaine mécanique. L'objet de cette description est un engin sur lequel cette mécanique est simplifiée grâce à un ou plusieurs propulseurs constitués d'ailerons flexibles formant palmes ou nageoires et actionnés par des oscillations dudit engin dans un plan horizontal. Sur les dessins annexés, donnés à titre d'exemples non limitatifs de formes de réalisation de l'objet de l'invention: les figures 1, 3 et 4 représentent un engin nautique avec palmes de fond et nageoire caudale, vu respectivement de dessous, en élévation et de l'avant, la figure 2 montre une palme en position ouverte (pointillé) et en position de repos, les figures 5 et 6 représentent un engin nautique avec deux nageoires axiales et nageoire caudale, vu respectivement de dessous et en élévation, les figures 7 et 8 représentent dans les mêmes conditions un engin nautique avec nageoire centrale unique, la figure* 9 montre, vu de dessous, un engin nautique à palmes latérales, et la figure 10 montre, vu de l'avant, une variante d'un tel engin à palmes inclinées.On existing vehicles, the transmission of users' movements to the thrusters requires a certain amount of mechanics. The object of this description is a machine on which this mechanics is simplified thanks to one or more propellants made up of flexible fins forming fins or fins and actuated by oscillations of said machine in a horizontal plane. In the appended drawings, given by way of nonlimiting examples of embodiments of the subject of the invention: FIGS. 1, 3 and 4 represent a nautical craft with bottom fins and caudal fin, seen respectively from below, in elevation and from the front, FIG. 2 shows a palm in the open position (dotted line) and in the rest position, FIGS. 5 and 6 represent a nautical craft with two axial fins and caudal fin, seen respectively from below and in elevation , FIGS. 7 and 8 represent, under the same conditions, a nautical machine with a single central fin, FIG. 9 shows, seen from below, a nautical machine with lateral fins, and FIG. 10 shows, seen from the front, a variant. of such a device with inclined fins.
Comme illustré sur les dessins annexés, l'engin est constitué d'une plate-forme 1 flottante circulaire ou ovoïde, dont la partie immergée est équipée de palmes de fond 2 et 3 ou latérales 11 et 12 diamétralement opposées (fixées suivant les pointillés sur la figure 1), et/ou d'une nageoire caudale 4, et/ou de nageoires axiales 13, 14 et/ou d'une nageoire centrale 15. Les palmes sont entrebâillées au repos (figure 2, trait plein).As illustrated in the accompanying drawings, the machine consists of a floating platform 1 circular or ovoid, the submerged part of which is fitted with bottom fins 2 and 3 or lateral fins 11 and 12 diametrically opposite (fixed along the dotted lines in Figure 1), and / or a caudal fin 4, and / or fins axial 13, 14 and / or a central fin 15. The fins are ajar at rest (Figure 2, solid line).
Pour actionner l'engin, l'utilisateur debout, déjaugeant l'avant, immerge la nageoire caudale, et par des torsions plus ou moins amples et saccadées, à droite et à gauche, de son corps accompagnées et transmises par les pieds, lui imprime des oscillations horizontales alternées autour d'un axe vertical passant par son centre. Entraînées par ces oscillations alternées, les palmes réagissent comme celles d'un palmipède l'une s'ouvrant 9, (figure 3), 3, (figure 4), et assurant la propulsion pendant que l'autre se plaque contre la plate-forme 1 2, (figure 4) et réciproquement. La nageoire caudale 4 propulse comme celle d'un têtard. Le changement de direction s'obtient par des impulsions plus puissantes d'un côté, et/ou, en déjaugeant la nageoire caudale dans le sens utile. La position de l'utilisateur est indépendante de la direction suivie.To operate the machine, the standing user, planing the front, immerses the caudal fin, and by more or less ample and jerky twists, to the right and to the left, of his body accompanied and transmitted by the feet, prints it alternating horizontal oscillations around a vertical axis passing through its center. Driven by these alternating oscillations, the fins react like those of a palmiped one opening 9, (figure 3), 3, (figure 4), and ensuring the propulsion while the other is pressed against the platform form 1 2, (figure 4) and vice versa. The tail fin 4 propels like that of a tadpole. The change of direction is obtained by more powerful impulses on one side, and / or, by planing the caudal fin in the useful direction. The position of the user is independent of the direction followed.
Un poids minimum de l'engin réduit les effets nuisibles de l'inertie lors de l'inversion de sens des oscillations. Ce poids minimum est obtenu par une plate-forme 1 monobloc en mousse semi-rigide à micro-cellules fermées dans laquelle les palmes pourront éventuellement être entaillées 9, (figure 3), et la nageoire caudale 4 découpée. Cette plate-forme ronde ou ovoïdale peut être divisible, et démontable ou articulée et repliable. La plate-forme 1 pourra avoir la forme d'un tronc de cône avec sommet dirigé veres le bas, et être équipée de palmes latérales 11, 12 inclinées (figure 10). Un poids minimum peut également être atteint par une plate-forme, fig 4, vue de face gonflable en plusieurs compartiments, notamment, une chambre à air 5 périphérique, et le volume centre 6 circonscrit par les parois 7 8. Les gonflements respectifs et mesurés de ces volumes confèrent à l'engin sa forme circulaire et la rigidité requises. Ces volumes sont contenus dans des enveloppes d'une extensibilité limitée, pouvant être transparentes.A minimum weight of the machine reduces the harmful effects of inertia when reversing the direction of the oscillations. This minimum weight is obtained by a monobloc platform 1 in semi-rigid foam with closed micro-cells in which the fins can possibly be notched 9, (FIG. 3), and the caudal fin 4 cut out. This round or oval platform can be divisible, and removable or articulated and foldable. The platform 1 could have the shape of a truncated cone with the top directed towards the bottom, and be equipped with lateral fins 11, 12 inclined (FIG. 10). A minimum weight can also be reached by a platform, fig 4, front view inflatable in several compartments, in particular, a peripheral air chamber 5, and the center volume 6 circumscribed by the walls 7 8. The respective and measured swellings of these volumes give the machine its circular shape and the required rigidity. These volumes are contained in envelopes of limited extensibility, which may be transparent.
Un emplacement central antidérapant, ou des cale-pieds pivotants et réglables 10, (figure 4) sont prévus. Les cale-pieds 10 pourront être de type enveloppant et fixés sur la plate-forme 1 au moyen de bandes à raicro-boucles et crochets ("Velcro"), ce qui permet d'adapter aisément leur position et d'éviter certains accidents, lors de l'exécution de figures d'acrobatie type "surf" par exemple.A non-slip central location, or swivel and adjustable toe clips 10, (Figure 4) are provided. The toe clips 10 may be of the enveloping type and fixed to the platform 1 by means of strips with micro-loops and hooks ("Velcro"), which makes it possible to easily adapt their position and avoid certain accidents, when performing "surf" type acrobatics, for example.
En eau libre un lien de sécurité relie l'engin et l'utilisateur.In open water, a safety link connects the machine and the user.
Tous les plans d'eau, de la pataugeoire à l'océan sont utilisables, soit pour des jeux, joutes, entrechocs, courses, poursuites, soit pour la promenade paisible, soit pour un surf innovant qui s'autopropulsant et se dirigeant debout permet de trouver aisément la vague propice. All the bodies of water, from the paddling pool to the ocean, can be used, either for games, jousting, bumps, races, chases, or for a peaceful walk, or for an innovative surf which propels itself and heads up allowing to easily find the right wave.
