Abstract

The board has a flat hull (1) with a keel (2) having, on its rear section, a cavity of domed shape to catch the water currents with a maximum traction coefficient. The hull can be tapering and recurved on its lower face. The hull has binding s for the users feet. It can have one or more fins (5,6). All the board components can be formed integrally. there can be a safety loop with a cable attached to an eye fitting around the users ankle.

Description

La présente invention concerne un nouvel engin de locomotion utilisant la force de trainée générée par les courants des voies d'eau intérieures pour se mouvoir.The present invention relates to a new locomotion machine using the drag force generated by the currents of inland waterways to move.

Ce véhicule est destiné à être à l'origine d'une nouvelle pratique sportive pouvant être appellée planche de rivières ou surf de rivières
Le dispositif selon l'invention permet:
- d' assurer la flotabilité de l'engin et de son pilote
- de piéger les veines d'eau permettant de mouvoir l'engin par l'utilisation de la force de
trainée
- d'effectuer des changements de direction sous l'impulsion du pilote II comporte une partie de forme plane prévue pour permettre au pilote de prendre appui, éffilée et légèrement recourbée en sous-face afin d'utiliser la force de portance le cas échéant, une partie inférieure en forme de quille destinée à fendre la surface de l'eau avec le minimum de perte de charges, notamment lors des changements de direction. Cet élément comporte en sa partie arrière une cavitée de forme galbée destinée à piéger les veines d'eau de façon à utiliser la force de trainée permettant de mouvoir l'ensemble.
This vehicle is intended to be at the origin of a new sporting practice which can be called river boarding or river surfing.
The device according to the invention allows:
- ensuring the buoyancy of the craft and its pilot
- to trap the veins of water making it possible to move the machine by the use of the force of
trail
- to carry out changes of direction under the impulse of the pilot II comprises a part of planar form intended to allow the pilot to take support, tapered and slightly curved under-face in order to use the force of lift if necessary a lower part in the form of a keel intended to split the surface of the water with the minimum pressure drop, especially during changes of direction. This element comprises in its rear part a cavity of curved shape intended to trap the veins of water so as to use the drag force making it possible to move the assembly.

Il est complété par une ou plusieurs dérives en partie arrière ayant pour fonction de maintenir l'ensemble dans la direction voulue par le pilote, et par deux éléments de fixation des pieds du pilote, le rendant ainsi solidaire de l'ensemble.It is completed by one or more drifts in the rear part whose function is to maintain the assembly in the direction desired by the pilot, and by two elements for fixing the feet of the pilot, thus making it integral with the assembly.

With reference to these drawings, the invention consists of a flat part (1) with a width of about 0.40 m, a length of about 1.50 m and a thickness of 0.07 to About 0.10 m from a keel-shaped part (2) with a thickness of 0.20 to 0.25 m and a length of about 1.10 m, from a hollow part of curved shape (3) with a depth of approximately 0.10 to 0.15 m. The assembly is completed by a fixing device (4) and by one or more fins (5) and (6).

Les dimensions ci-avant indiquées sont établies à titre d'exemple non limitatif.The dimensions indicated above are established by way of nonlimiting example.

Selon un premier procédé de fabrication
- les parties (1) et (2) jusque légèrement au dessus de la ligne de flottaison sont constituées d'une pièce moulée en alliage léger d'une épaisseur la plus faible possible tout en respectant les containtes de chocs envisageables dans les cours d'eau les plus accidentés
- le remplissage de cette pièce ainsi que la partie (2) au dessus de la ligne de flottaison sont faits en mousse de polyuréthane poncée ou usinée, recouverte d'une résine nautique pour la partie extérieure
Selon un autre procédé:
- I'ensemble du dispositif (1) et (2) est constitué d'une épaisseur de plastique rigide (le polymère exact étant à définir) la forme étant obtenue par moulage sous pression, le noyau est constitué d'un vide d'air
Selon un autre procédé
- I'ensemble (1) et (2) est obtenu par moulage autour d'un noyau, soit d'un seul tenant, soit en deux éléments assemblés par soudure thermique ou par ultrasons. La sous-face de l'ensemble pouvant être protégée par une tôle emboutie épousant parfaitement ses formes,
I'assemblage étant réalisé par collage.
According to a first manufacturing process
- the parts (1) and (2) up to slightly above the waterline consist of a molded piece of light alloy with the smallest possible thickness while respecting the shock containments that can be envisaged in the courses most damaged water
- the filling of this part as well as the part (2) above the waterline are made of sanded or machined polyurethane foam, covered with a nautical resin for the external part
According to another method:
- the whole of the device (1) and (2) consists of a thickness of rigid plastic (the exact polymer being to be defined) the shape being obtained by pressure molding, the core consists of a vacuum
According to another method
- The assembly (1) and (2) is obtained by molding around a core, either in one piece, or in two elements assembled by thermal welding or by ultrasound. The underside of the assembly can be protected by a stamped sheet perfectly matching its shapes,
The assembly being carried out by gluing.

Selon un autre procédé identique au précédant, la matrice est en mousse de polyuréthane moulée et constitue le noyau définitif de l'ensemble (1) et (2)
En ce qui concerne les composants annexes, sont prévus les éléments ci-après
- deux dispositifs de fixation des pieds du pilote sur l'engin (4), composés soit de simples bandes de coutchouc pré-formées, soit de systèmes plus élaborés, se rapprochant de ceux utilisés pour le ski nautique.
According to another process identical to the previous one, the matrix is made of molded polyurethane foam and constitutes the final core of the assembly (1) and (2)
With regard to the ancillary components, the following elements are provided
- two devices for fixing the pilot's feet to the machine (4), composed either of simple pre-formed rubber bands, or of more sophisticated systems, similar to those used for water skiing.

- une ou plusieurs dérives (5) et (6) dont la forme et la composition - métal ou polymère, intégrée(s) ou rapportée(s) - seront définies précisemment après les tests sur prototypes. - one or more drifts (5) and (6) whose shape and composition - metal or polymer, integrated (s) or added (s) - will be defined precisely after the tests on prototypes.

- un dispositif de sécurité constitué d'un câble synthétique terminé par un anneau en caoutchouc à mettre autour de la cheville avant du pilote, relié à l'avant de l'engin, soit en matière élastique, soit terminé par un petit enrouleur automatique. Ce système devant permettre d'éviter la perte de l'engin en cas de chute du pilote, ainsi que sa mise en position à contre-courant de façon à faciliter sa reprise en main. Cet élément est mentionné à titre indicatif et ne fait pas partie de la présente invention.  - a safety device consisting of a synthetic cable terminated by a rubber ring to be put around the front ankle of the pilot, connected to the front of the craft, either in elastic material, or terminated by a small automatic winder. This system should make it possible to avoid the loss of the machine in the event of a fall of the pilot, as well as its setting in position against the current so as to facilitate its recovery. This element is mentioned for information only and is not part of the present invention.
