Abstract
Description
L'objet de l'invention concerne un flotteur à propulsion musculaire. The object of the invention relates to a muscle-propelled float.
Il est destiné à assurer en même temps que la sustentation, 1 ' avancement par propulseur stabilise subissant un flou- vement d'enfoncement et de rélèvement alternatif. It is intended to ensure at the same time as the lift, the advancement by propellant stabilizes undergoing a buoyancy of recess and alternating lifting.
Dans les dispositifs connus constitués par un flotteur il était difficile de permettre à l'usager son maintien en position verticale et son avancement par propulseurs placés de part et d'autre de l'engin. In the known devices constituted by a float, it was difficult to allow the user to keep it in an upright position and to advance it by thrusters placed on either side of the machine.
Le dispositif suivant l'invention supprime cet inconvénient et donne la possibilité à l'utilisateur d'assurer son maintien en une position verticale tout en manoeuvrant alternativement les éléments de propulsion provoquant un avancement orienté et rapide. The device according to the invention eliminates this drawback and gives the user the possibility of ensuring that it is kept in a vertical position while alternately maneuvering the propulsion elements causing oriented and rapid advancement.
I1 est constitué par la combinaison de câbles souples ayant leur point fixe à l'arrière sur les ailes d'un stabilisateur et leur point d'attache à l'avant sur un secteur élastique avec les éléments propulseurs fixés en un point déterminé, mais déplaçables suivant les nécessités à la commande. I1 is constituted by the combination of flexible cables having their fixed point at the rear on the wings of a stabilizer and their point of attachment at the front on an elastic sector with the propellants fixed at a determined point, but movable according to the needs when ordering.
Sur les dessins annexés donnés à titre d'exemple non limitatif d'une des formes de réalisation de l'objet de l'invention
La figure 1 montre le flotteur vu en plan.In the accompanying drawings given by way of nonlimiting example of one of the embodiments of the subject of the invention
Figure 1 shows the float seen in plan.
Les figures 2 et 3 représentent les détails constructifs des éléments de propulsion. Figures 2 and 3 show the construction details of the propulsion elements.
La figure 4 est une vue en élévation de l'ensemble du dispositif. Figure 4 is an elevational view of the entire device.
Le flotteur 1 est constitué par un élément de préférence plan ( Fis, 1),
I1 comporte à sa partie arrière un stabilisateur avec ailes profilées 2, 3.The float 1 is constituted by a preferably planar element (Fis, 1),
I1 has at its rear part a stabilizer with profiled wings 2, 3.
Ces ailerons rigides, pouvant être remplacés par une tige servent de points d'attaches fixes 4, 5, aux câbles souples 6, 7. Ils sont préférentiellement placés en position médiane de l'épaisseur du flotteur, de façon que suivant les déplacements, ils puissent être immergés ou pas. These rigid fins, which can be replaced by a rod serve as fixed attachment points 4, 5, to the flexible cables 6, 7. They are preferably placed in the middle position of the thickness of the float, so that according to the movements, they may or may not be submerged.
Ces câbles ont les extrémités de leurs brins 8, 9, relis à une attache élastique 10 qui cercle l'avant 11 du flot teur- et est immobilisé sur ce dernier. These cables have the ends of their strands 8, 9, connected to an elastic clip 10 which circles the front 11 of the float tor- and is immobilized on the latter.
Les éléments de propulsion 13, 14, sont retenus de part et d'autre du flotteur 1 par les câbles 6, 7, au moyen d' une boucle 15. Ces câbles souples et indépendants assurent le rappel des éléments propulseurs en toutes positions. The propulsion elements 13, 14 are retained on either side of the float 1 by the cables 6, 7, by means of a loop 15. These flexible and independent cables ensure the return of the propulsion elements in all positions.
Les extrémités de ces tiges sont pourvues de palmes 16, 17. The ends of these rods are provided with fins 16, 17.
Ces tiges sont alternativement enfoncées, flèche A et relevées, flèche B afin que leur mouvement ondulatoire assure la propulsion de l'engin (Fig 4). These rods are alternately driven in, arrow A and raised, arrow B so that their wave movement ensures the propulsion of the machine (Fig 4).
Le mouvement peut également être simultané. The movement can also be simultaneous.
Ce dispositif est adaptable aux planches à voile et tous autres flotteurs de même type. This device is adaptable to windsurfers and all other floats of the same type.
Le câble souple dont chaque brin 6, 7, indépendant est relié à l'élément élastique 10 peut effectuer indépendamment un mouvement présentant une amplitude variable pour modifier 0a vitesse d'avancement. The flexible cable of which each independent strand 6, 7 is connected to the elastic element 10 can independently perform a movement having a variable amplitude to modify the forward speed.
Leur attache 15, 15' permet leur stabilisation de part et d' autre de 1 'usager, sans entraver ses mouvements. Elle stabilise l'ensemble et en fait un tout, parfaitement homogène facilitant l'utilisation du flotteur ainsi que sa manoeuvre ; C'est ainsi qu'il est possible de faire marche arrière, tourner sur place en modifiant l'orientation, le positionnement des éléments de propulsion. Their attachment 15, 15 ′ allows their stabilization on either side of the user, without hampering his movements. It stabilizes the whole and makes it a whole, perfectly homogeneous facilitating the use of the float as well as its operation; This is how it is possible to reverse, turn on the spot by changing the orientation, the positioning of the propulsion elements.
Toutefois les formes, dimensions et dispositions des différents éléments pourront varier dans la limite des équivalents comme d'ailleurs les matières utilisées pour leur fabrication, sans changer pour celà la conception générale de l'invention qui vient d'être décrite. However, the shapes, dimensions and arrangements of the various elements may vary within the limit of the equivalents, as moreover the materials used for their manufacture, without changing the general conception of the invention which has just been described.
