Abstract
Description
La présente invention concerne un appareil nautique propulsé par son utilisateur et, plus précisément, un tel appareil propulsé sous l'influence du poids propre de son utilisateur en position debout, agissant par enfoncement de pédales. The present invention relates to a nautical device powered by its user and, more specifically, such a device powered under the influence of the self-weight of its user in the standing position, acting by depressing the pedals.
Dans la technique actuelle, on connaît de nombreux types d'appareils nautiques propulsés par des aubes ou des helices mises en rotation sous l'action d'un pédalier ou d'un vilebrequin, lui-même entraîné en rotation par l'effort des jambes d'un utilisateur installé en position assise. Ces appareils connus de longue date comportent, en général, deux flotteurs sous forme de réservoirs étanches. In the current technique, many types of nautical apparatus are known, propelled by blades or propellers set in rotation under the action of a crankset or a crankshaft, itself driven in rotation by the effort of the legs. of a user installed in a seated position. These devices which have been known for a long time generally have two floats in the form of sealed tanks.
Contrairement à ces appareils connus, l'appareil nautique selon l'invention est constitué d'une coque unique fermée sur laquelle l'utilisateur se tient en position debout. Unlike these known devices, the nautical device according to the invention consists of a single closed shell on which the user stands in a standing position.
Selon l'invention, un tel appareil nautique, conçu de préférence pour une seule personne, est constitué d'une coque fermee, effilée à l'avant et plongeante à l'arrière, comportant, d'une part, dans la partie correspondant à son centre de gravité, deux pédales dont chacune est montée sur deux leviers oscillants sous forme d'un parallélogramme articulé et, d'autre part, pourvue dans sa partie arrière de deux plateaux pousseurs montés sur des soufflets et debouchant de l'arrière de la coque sous la ligne de flottaison de celle-ci, chaque plateau etant respectivement relié par une tringlerie à une des pedales correspondantes. According to the invention, such a nautical device, preferably designed for a single person, consists of a closed hull, tapered at the front and plunging at the rear, comprising, on the one hand, in the part corresponding to its center of gravity, two pedals, each of which is mounted on two oscillating levers in the form of an articulated parallelogram and, on the other hand, provided in its rear part with two pusher plates mounted on bellows and emerging from the rear of the hull under the waterline thereof, each plate being respectively connected by a linkage to one of the corresponding pedals.
De manière plus spécifique, chaquepédale est du type à enfoncement et ses deux leviers oscillants de support sont montés en paral lèle et en inclinaison vers l'arrière de la coque, afin qu'en course descendante elle se déplace vers l'arrière tout en restant en position horizontale. D'autre part, la partie arrière de chaque pédale est reliée, en tête de son levier arrière, par une tige rigide, au plateau pousseur qui lui correspond, ce plateau etant lui-même guidé dans ses mouvements de va et vient par une tige coulissante.Par ailleurs, chaque tige coulissante associée à une extremite à son plateau pousseur est rappelée, à son autre extrémité, par un ressort qui est conçu de force suffisante pour ramener, par l'intermédiaire de la tige rigide, la pédale correspondante en position haute lorsque celle-ci ne subit plus de pression d'enfoncement. En outre, chaque pédale comporte, comme chaque plateau pousseur, un soufflet environnant relie aux bords de l'ouverture du pont de la coque prévue pour cette pédale, afin d'assurer I'étanchéité. A noter que les soufflets d'étanchéité des plateaux pousseurs sont de préférence en forme de soufflet d'accordéon, alors que ceux des pédales peuvent être prévus elasiques bien que de forme ondulée.En outre, de preference et afin d'assurer l'équilibre de l'utilisateur, la corde d'amarrage de l'appareil accrochee à l'avant est conçue de manière que l'utilisateur puisse, en position debout sur les pedales, la prendre en mains pour ne pas basculer en arrière lors de la manoeuvre d'enfoncement des pedales et, par là, suite au glissement en avant de la coque. More specifically, each pedal is of the depressing type and its two oscillating support levers are mounted in parallel and in inclination towards the rear of the shell, so that in downward travel it moves rearward while remaining in horizontal position. On the other hand, the rear part of each pedal is connected, at the head of its rear lever, by a rigid rod, to the pusher plate which corresponds to it, this plate being itself guided in its back and forth movements by a rod. Furthermore, each sliding rod associated with one end to its pusher plate is recalled, at its other end, by a spring which is designed with sufficient force to return, by means of the rigid rod, the corresponding pedal to the position high when it is no longer subjected to pressing pressure. In addition, each pedal includes, like each pusher plate, a surrounding bellows which connects to the edges of the opening of the deck of the shell provided for this pedal, in order to ensure sealing. Note that the sealing bellows of the pushing plates are preferably in the form of an accordion bellows, while those of the pedals can be provided elastic although of wavy shape. In addition, preferably and in order to ensure balance of the user, the mooring rope of the device attached to the front is designed so that the user can, while standing on the pedals, take it in hand so as not to tip backwards during the maneuver depression of the pedals and, there, following the sliding forward of the hull.

Comme on le remarque de ces figures, l'appareil selon l'invention est constitué d'une coque fermée 1, effilée à l'avant 2 et plongeante à l'arrière 3. Cette coque comporte, dans sa partie correspondant sensiblement à son centre de gravité, deux pedales 7a et 7b. Chaque pédale est montée sur deux leviers oscillants 8a et 8b formant une sorte de pa rallélogramme articulé. Cette coque comporte, en outre, montés dans sa partie arrière 3, deux plateaux pousseurs 9a et 9b, pourvus chacun d'un soufflet 10 le reliant de maniere étanche à la paroi arrière 11 de la coque.Ces deux plateaux pousseurs débouchent, de préférence, sous la ligne de flottaison de l'appareil, afin d'assurer une plus grande surface de poussee sur l'eau, et sont reliés respectivement par une tringlerie, que l'on décrira ci-après, à la pédale correspondante. As can be seen from these figures, the device according to the invention consists of a closed shell 1, tapered at the front 2 and plunging at the rear 3. This shell comprises, in its part corresponding substantially to its center of gravity, two pedals 7a and 7b. Each pedal is mounted on two oscillating levers 8a and 8b forming a sort of articulated parallelogram. This shell further comprises, mounted in its rear part 3, two pusher plates 9a and 9b, each provided with a bellows 10 sealingly connecting it to the rear wall 11 of the shell. These two pusher plates preferably open out. , below the waterline of the apparatus, in order to ensure a greater thrust surface on the water, and are connected respectively by a linkage, which will be described below, to the corresponding pedal.
Chaque pédale 7a,7b est du type à enfoncement sous le poids propre de l'utilisateur et ses deux leviers oscillants 8a,8b de support sont articulés en parallele avec une légère inclinaison vers l'arrière en position de repos, comme on le voit dans la figure 2, la pédale restant en position horizontale. La partie arrière de chaque pédale, en tête de son levier arrière 8b, est reliée par une tringlerie, sous forme d'une tige rigide 12, à une tige coulissante 13, elle-même solidaire par son extrémité arriere d'un plateau pousseur.Cette tige coulissante 13 est rappelée à son extrémité oppose au plateau par un ressort 14, conçu de force suffisante pour, non seulement ramener le plateau en direction de 1 arrière de la coque, mais également relever la pédale correspondante en position de repos, par l'intermédiaire de la tige rigide 12, lorsque l'utilisateur n'agit plus sur cette pédale. En outre, chaque pédale comporte un soufflet élastique 15 environnant, relie de manière etanche à l'ouverture 16a,16b du pont de la coque prevue pour le passage de chaque pédale. Each pedal 7a, 7b is of the push-in type under the user's own weight and its two oscillating levers 8a, 8b for support are articulated in parallel with a slight inclination towards the rear in the rest position, as seen in Figure 2, the pedal remaining in the horizontal position. The rear part of each pedal, at the head of its rear lever 8b, is connected by a linkage, in the form of a rigid rod 12, to a sliding rod 13, itself secured by its rear end to a pusher plate. This sliding rod 13 is recalled at its end opposite the plate by a spring 14, designed with sufficient force to not only bring the plate back towards the rear of the hull, but also raise the corresponding pedal to the rest position, by l 'intermediate of the rigid rod 12, when the user no longer acts on this pedal. In addition, each pedal has an elastic bellows 15 surrounding it, sealingly connects to the opening 16a, 16b of the deck of the shell provided for the passage of each pedal.
A noter que, de préférence, chaque soufflet 10 devplateau pousseur est de forme en accordeon. En outre, afin d'assurer l'équilibre de l'utilisateur lorsqu'il agit sur les pédales, une corde 17, prévue pour l'amarrage de l'appareil, est adaptée pour être prise en mains par l'utilisateur afin qu'il ne bascule pas en arrière. It should be noted that, preferably, each bellows 10 of the pushing plate is of accordion shape. In addition, in order to ensure the balance of the user when he acts on the pedals, a rope 17, provided for mooring the device, is adapted to be taken in hand by the user so that it does not tip back.
