Abstract

The floats, shaped as skis, are for moving on water and have openings (8) in the centre for the user's feet. The base of each float (3) is curved and the bilge (5) is highly rounded but the corner (4) at the inner side (2) is sharp. The base has one or more grooves (6) along it. The inner side of each float is flat or slightly convex in the centre and is rounded towards the extremities. The user's foot is held in a shaped recess (9) by a plug of supple material and a cover (11).

Description

La présente invention concerne les déplacements autonomes de l'homme sur les eaux agitées. The present invention relates to the autonomous movements of man on rough waters.

Diverses inventions destinées à permettre à l'homme de se propulser, en position debout, sur la surface de l'eau ont déjà été decrites depuis le 19 aout 1915 (brevet 480 278). Toutefois de telles inventions ne pouvaient être utilisées en rivière sportive, car la présence de quilles ou dérives sous le fond (brevets : 6924442 (1969) ; 229 4726 (1974) ; 227 6072 (1974) de volets dans les skis de fond sur l'eau (brevets : 237 6672 (1977) ; 233 8723 (1976) de configuration spéciale du bordage (brevets : 240 0926 (1978) 229 9885 (1975) interdisaient la pratique de virages "stop-courant" et ainsi limitaient considérablement les possibilités de manoeuvre en rivières sportives car ces skis offraient une résistance élevée au dérapage latéral. Various inventions intended to allow man to propel himself, in a standing position, on the surface of the water have already been described since August 19, 1915 (patent 480,278). However, such inventions could not be used in sport rivers, because the presence of skittles or daggerboards under the bottom (patents: 6924442 (1969); 229 4726 (1974); 227 6072 (1974) of flaps in cross-country skis on the 'water (patents: 237 6672 (1977); 233 8723 (1976) of special planking configuration (patents: 240 0926 (1978) 229 9885 (1975) prohibited the practice of "stop-current" turns and thus considerably limited the possibilities maneuvering in sporting rivers because these skis offered a high resistance to lateral skidding.

Le dispositif suivant l'invention permet d'éviter ces inconvénients car il est conçu de telle sorte qu'il peut d'une part accrocher la surface de l'eau et ainsi permettre de prendre appui sur elle et d'autre part il peut deraper sur l'eau. The device according to the invention makes it possible to avoid these drawbacks because it is designed in such a way that it can, on the one hand, hang the surface of the water and thus make it possible to rest on it and, on the other hand, it can undermine on the water.

Le dispositif objet de la présente invention comporte deux flotteurs ou skis sur lesquels sont fixés au moyen d'un dispositif décrit plus loin les pieds de l'utilisateur. Ces deux flotteurs sont symétriques l'un de l'autre par rapport à un plan médian. Le fond de chaque flotteur est plus ou moins gironne. Ce fond est relié au côte externe par des bouchains très arrondis par contre il forme avec le côté interne un angle, sur tout ou partie de la longueur, appelé care qui peut éventuellement faire saillie par rapport au flotteur ; cet angle peut selon différents modes de réalisation avoir un sommet vif ou légèrement arrondi. Le côté externe est convexe par rapport au plan de symetrie des deux skis. Le côté interne est parallèle au plan de symétrie des deux skis, il peut être plan ou légèrement concave ou légèrement convexe.Le fond peut être muni d'une ou plusieurs cannelures Le pont de forme quelconque est muni dans sa partie centrale d'une cavité étanche en forme de cheminée afin d'y loger le pied de l'utilisateur. Le pied de l'utilisateur est cale par une empreinte à sa forme fixee au fond de la cheminée tandis qu'un bouchon en matière souple en appui sur le coup de pied maintient le pied dans la cheminée. Ce bouchon est maintenu par un pontage qui assure l'étanchéité de la cheminée. The device object of the present invention comprises two floats or skis on which are fixed by means of a device described below the feet of the user. These two floats are symmetrical to each other with respect to a median plane. The bottom of each float is more or less gironne. This bottom is connected to the external side by very rounded chines, on the other hand it forms with the internal side an angle, over all or part of the length, called care which can possibly protrude with respect to the float; according to different embodiments, this angle can have a sharp or slightly rounded apex. The outer side is convex relative to the plane of symmetry of the two skis. The internal side is parallel to the plane of symmetry of the two skis, it can be flat or slightly concave or slightly convex.The bottom can be provided with one or more splines The bridge of any shape is provided in its central part with a cavity waterproof in the form of a chimney in order to accommodate the user's foot. The user's foot is wedged by an imprint of its shape fixed to the bottom of the chimney while a plug made of flexible material resting on the kick keeps the foot in the chimney. This plug is maintained by a bypass which ensures the tightness of the chimney.

Les dessins illustrent à titre d'exemple un mode de réalisation du dispositif conforme à l'invention. Les deux faces externes 1 des skis sont convexes, les faces internes 2 sont planes, le fond 3 est légèrement gironné. The drawings illustrate by way of example an embodiment of the device according to the invention. The two outer faces 1 of the skis are convex, the inner faces 2 are planar, the bottom 3 is slightly girled.

La face interne 2 forme avec le fond 3 un angle vif 4 tandis que le fond se prolonge sur la face externe par un bouchain très arrondi 5. Le fond est muni d'une canelure 6 dont les bords forment avec le fond deux angles 7 qui peuvent être vifs ou très légèrement arrondis. Le pied est maintenu dans la cheminée 8 par une cale 9.et par un bouchon 10 lui-même maintenu par un pontage 11 fixé au pont par un élastique enserrant l'hilloire 12. La fixation du pied est renforcée par une sangle passant sur le bouchon 13 et fixé par un moyen quelconque au ski. Une cordelette de sécurité libère l'attache en cas de chute de l'utilisateur. La propulsion est assurée au moyen d'une pagaie double suffisamment longue et dont l'attaque de la pelle peut être avancée.The internal face 2 forms with the bottom 3 a sharp angle 4 while the bottom is extended on the external face by a very rounded chine 5. The bottom is provided with a groove 6 whose edges form with the bottom two angles 7 which may be bright or very slightly rounded. The foot is held in the chimney 8 by a wedge 9. and by a plug 10 itself held by a bridging 11 fixed to the bridge by an elastic band enclosing the coaming 12. The fixing of the foot is reinforced by a strap passing over the plug 13 and fixed by any means to the ski. A safety cord releases the clip in the event of the user falling. Propulsion is ensured by means of a sufficiently long double paddle, the attack of the shovel of which can be advanced.

Le dispositif objet de la présente invention permet d'étendre le domaine nautique skiable à la rivière sportive jusqu'ici réservée aux canoës et kayaks ; l'invention permet d'y effectuer les mêmes parcours aussi bien pour le loisir que pour la compétition.  The device which is the subject of the present invention makes it possible to extend the nautical ski area to the sporting river hitherto reserved for canoes and kayaks; the invention makes it possible to carry out the same courses there as well for the leisure as for the competition.
