Abstract
Description
La présente invention concerne un dispositif basé sur la ventouse, en vueThe present invention relates to a device based on the suction cup, in view
de laof the
fixation amovible de dérive, ailerons, foil ou autres dispositifs hydrodynamique de stabilisation et de guidage, cette fixation devant s'effectuer sur ou principalement sous divers objets flottants tels que la planche à voile, la planche de surf, le ski nautique, le wakeboard, le kitesurf, les bateaux et leurs divers types de coques. removable drift attachment, ailerons, foil or other hydrodynamic stabilization and guidance devices, this attachment must be carried out on or mainly under various floating objects such as windsurfing, surfboards, water skiing, wakeboarding, kitesurfing, boats and their various types of hulls.
Jusqu'à présent cette fixation s'effectuait, soit de manière rigide et non amovible, soit au moyen de boîtiers de type: puits de dérive (système rétractable ou non), us box, trim box, tuttle box etc... Until now, this fixing was carried out either rigidly and not removable, or by means of boxes of the type: drift well (retractable system or not), us box, trim box, tuttle box, etc.
Le dispositif par ventouse proposé n'implique aucune altération ou modification 10 des objets flottants précités (vissage, collage, soudage, présence de boîtiers...). De ce fait, en cas de casse, il permet le remplacement immédiat des stabilisateurs ou auxiliaire de guidage sans l'intervention d'un atelier. Pour l'initiation a la planche à voile, la présence d'une dérive stabilisatrice auxiliaire est d'une grande utilité, il est par contre souhaitable de pouvoir la supprimer aisément une fois les bases techniques du sport 15 acquises. The proposed suction device does not imply any alteration or modification of the aforementioned floating objects (screwing, gluing, welding, presence of housings, etc.). Therefore, in the event of breakage, it allows the immediate replacement of the stabilizers or guiding auxiliary without the intervention of a workshop. For initiation to windsurfing, the presence of an auxiliary stabilizing fin is of great use, it is however desirable to be able to easily remove it once the technical basics of the sport have been acquired.
L'invention proposée permet donc d'utiliser la même planche tant comme instrument d'initiation qu'a l'usage d'un sportif averti.. The proposed invention therefore allows the same board to be used both as an initiation instrument and for the use of an experienced sportsperson.
Les dessins annexés illustrent l'invention: La figure 1 représente de profil la dérive en position de repos, ventouse désactivée. 20 La figure 2 représente de profil la dérive en position fonctionnelle, ventouse activée. The accompanying drawings illustrate the invention: FIG. 1 shows in profile the fin in the rest position, suction cup deactivated. FIG. 2 shows in profile the drift in the functional position, with the suction cup activated.
La figure 3 représente en coupe la dérive en position fonctionnelle, ventouse activée. Figure 3 shows in section the drift in the functional position, suction cup activated.
En référence à ces dessins, le dispositif comporte une ventouse (1), disque en matériel élastique déformable venant, en position activée (fig. 2), s'emboîter dans une coupelle rigide (2), créant de la sorte un vide d'air (3) entre elle-même et la surface de 25 l'engin nautique (4) sur laquelle s'effectue la fixation. Un disque rigide (5) est solidaire, d'une part de la ventouse (1) d'autre part d'un axe de liaison (6) qui a pour fonction l'activation de la ventouse (1). Sa désactivation s'effectue automatiquement par le ressort (7). With reference to these drawings, the device comprises a suction cup (1), a disk made of deformable elastic material which, in the activated position (fig. 2), fits into a rigid cup (2), thereby creating a vacuum of air (3) between itself and the surface of the watercraft (4) on which the attachment is made. A rigid disc (5) is integral on the one hand with the suction cup (1) and on the other with a connecting pin (6) which has the function of activating the suction cup (1). It is deactivated automatically by the spring (7).
Mécanisme d'activation: La dérive (8) est fixée sur l'axe de liaison (6) au moyen d'un pivot de rotation (9). Activation mechanism: The fin (8) is fixed to the connecting axis (6) by means of a pivot pivot (9).
L'activation de la ventouse (1) s'effectue en basculant la dérive (8) depuis une position au repos (fig. 1). The suction cup (1) is activated by tilting the fin (8) from a rest position (fig. 1).
En sa position fonctionnelle (fig.2), le relèvement de l'axe de liaison (6) étant égal à la différence des longueurs de segments (AC-AB) (fig. 1). Précisons que le pivot de rotation (9) est placé a proximité du bord d'attaque (10), de ce fait l'effet hydrodynamique va dans le sens du basculement de la dérive (8) dans sa position fonctionnelle (fig.2) et donc du maintien de la ventouse (1), dans sa position activée (fig.2) ( la désactivation ne 10 pouvant ce faire que volontairement à l'arrêt). In its functional position (fig. 2), the raising of the connecting pin (6) being equal to the difference of the segment lengths (AC-AB) (fig. 1). Note that the pivot pivot (9) is placed near the leading edge (10), therefore the hydrodynamic effect goes in the direction of tilting of the fin (8) in its functional position (fig. 2) and therefore maintaining the suction cup (1) in its activated position (fig. 2) (deactivation can only do this voluntarily when stopped).
La géométrie extérieur de la coupelle rigide (2) et le profil sommital (11) de la dérive sont ajustés de manière à s'emboîter le long de la ligne (DEF) (fig.2), ceci permettant l'immobilisation de la dérive (8) par le jeu conjoint de la prise d'appui sur la ligne (DEF), et de traction exercée par la ventouse sur le pivot (9). Le long de la ligne 15 (DEF) une rainure additionnelle pourra de plus être prévue pour améliorer cette stabilisation.. The external geometry of the rigid cup (2) and the top profile (11) of the fin are adjusted so as to fit together along the line (DEF) (fig. 2), this allowing the fin to immobilize (8) by the joint play of the support socket on the line (DEF), and of traction exerted by the suction cup on the pivot (9). Along line 15 (DEF) an additional groove may also be provided to improve this stabilization.
Le dispositif selon l'invention est particulièrement destiné à l'industrie nautique. The device according to the invention is particularly intended for the nautical industry.
