Description
VELO NAUTIQUE PROPULSE PAR UN JET D'EAU NAUTICAL BIKE PROPELLED BY A WATER JET
1) DOMAINE TECHNIQUE AUQUEL SE RAPPORTE L'INVENTION La présente invention se situe dans le secteur technique des engins nautiques de sports et de loisirs non motorisés. Il s'agit d'un vélo nautique propulsé par un jet d'eau. Cette invention est destinée principalement à l'usage des amateurs de sports nautiques et des cyclistes qui veulent pratiquer leurs activités sur des lacs, des cours d'eau ou en bord de mer. Elle peut exister en version monoplace ou en tandem. TECHNICAL FIELD TO WHICH THE INVENTION RELATES The present invention is in the technical sector of non-motorized water sports and leisure equipment. It is a nautical bike powered by a jet of water. This invention is intended primarily for the use of water sports enthusiasts and cyclists who want to practice their activities on lakes, rivers or seaside. It can exist in single-seat or tandem.
2) DESCRIPTION DE L'ETAT DE LA TECHNIQUE ANTERIEURE Dans le domaine du vélo nautique, non statique, les techniques antérieures consistent à adapter des flotteurs rigides ou gonflables à un vélo pour permettre sa flottaison. Les pédales du vélo entraînent directement ou indirectement un système de propulsion par hélice ou roue à aube. Le guidon permet d'orienter directement ou indirectement le gouvernail qui dirige l'embarcation. La publication FR 2 693 427 est un exemple concret de ce type de réalisation. 2) DESCRIPTION OF THE STATE OF THE PRIOR ART In the field of nautical cycling, non-static, the prior art consists in adapting rigid or inflatable floats to a bicycle to allow its flotation. The bike pedals drive directly or indirectly a propulsion system propeller or impeller. The handlebar allows direct or indirect steering the rudder that directs the boat. The publication FR 2 693 427 is a concrete example of this type of embodiment.
On adapte aussi un système de motorisation mécanique, comprenant une hélice ou turbine qui est mise en rotation sous l'action des pédales, à des embarcations flottantes pour assurer leur propulsion. La publication WO 2005/108201 Al décrit l'adaptation d'un tel mécanisme à un canoë. It also adapts a mechanical motorization system, comprising a propeller or turbine which is rotated under the action of the pedals, to floating boats to ensure their propulsion. Publication WO 2005/108201 A1 describes the adaptation of such a mechanism to a canoe.
De la publication FR2 782 694 est connu un cycle à deux roues qui peut circuler sur des surfaces différentes. Ce dispositif comporte, en particulier, des nageoires qui s'ouvrent et se ferment en permettant au vélo d'avancer dans l'eau, sa flottaison étant assurée par des flotteurs fixés sur le cadre du vélo. From FR2 782 694 is known a two-wheel cycle that can travel on different surfaces. This device comprises, in particular, fins that open and close allowing the bike to advance in the water, its flotation being provided by floats attached to the frame of the bike.
Ces inventions présentent plusieurs inconvénients. Elles sont encombrantes et difficilement transportables même si elles sont démontables. En général, elles ne sont pas stables car dans certains cas leur centre de gravité est situé au dessus du niveau de la surface d'eau. Ces embarcations se déplacent grâce à une propulsion assurée par les pieds sur un pédalier et se dirigent à l'aide d'un guidon, mais elles ne permettent pas à l'utilisateur de se mouvoir dans l'eau comme il le fait avec un vélo dans l'air. These inventions have several disadvantages. They are bulky and difficult to transport even if they are removable. In general, they are not stable because in some cases their center of gravity is above the level of the water surface. These boats move thanks to a propulsion provided by the feet on a pedal and move with the help of a handlebar, but they do not allow the user to move in the water as it does with a bike in the air.
La présente invention vise donc à remédier à ces inconvénients. Elle est de faible encombrement et peut être rangée et transportée facilement. Par construction, la densité par rapport à l'eau du vélo nautique propulsé par un jet d'eau est légèrement inférieure à 1 ce qui assure sa flottabilité. Le centre de gravité du vélo nautique est situé en dessous de la surface d'eau ; ce qui assure sa stabilité. Ce vélo permet la pratique du sport nautique et du cyclisme dans un milieu aquatique et qui, de plus, est capable d' hydro massage.

By construction, the density relative to the water of the nautical bicycle propelled by a jet of water, when the tank float is empty, is slightly less than 1; which ensures its buoyancy. When the float tank is filled with water, the density relative to the water of the water bike is equal to 1; which allows to dive with the nautical bike. The center of gravity of the water bike is located below the water surface; which ensures its stability. With reference to the figures, the nautical bicycle propelled by a jet of water according to the present invention comprises: - A frame (5) which allows to assemble the various elements of the boat.
