Abstract
Description
La présente invention se caractérise par un système permettant une fixation à angle variable par rapport au mât. The present invention is characterized by a system allowing fixing at a variable angle relative to the mast.
Les dispositifs de poignée existants fixent toujours le mât à 900, donc le wishbone se trouve perpendiculaire au mât alors que les véliplanchistes fixent le wishbone plus ou moins haut sur le mât suivant leur taille. I1 est donc rare que le wishbone se trouve à 900 par rapport au mât. I1 peut se trouver souvent à moins de 900 et plus rarement à plus de 900, ce qui rend la fixation mât-poignée moins solidaire, entraînant beaucoup de "jeu", inconvénient majeur pour la compétition et l'usure prématurée du mât et de la poignée. The existing handle devices always fix the mast at 900, so the wishbone is perpendicular to the mast while windsurfers fix the wishbone more or less high on the mast according to their size. It is therefore rare for the wishbone to be 900 relative to the mast. It can often be less than 900 and more rarely more than 900, which makes the mast-handle fixing less integral, leading to a lot of "play", a major drawback for competition and premature wear of the mast and the handle.
Quelques tentatives ont été faites pour solutionner ce problème.Some attempts have been made to resolve this problem.
Elles se caractérisent par deux articulations à la liaison poignée-tube du wishbone, provoquant un effet de manivelle extrêmement nuisible.They are characterized by two joints at the handle-tube connection of the wishbone, causing an extremely harmful crank effect.
L'objet de l'invention a pour but de supprimer complètement ce défaut tout en gardant la qualité première d'une bonne
A poignée de wishbone - sa forte rigidité latérale - grâce à une articulation intégrée et compacte permettant une fixation à angle variable par rapport au mât, dans la position souhaitée.The object of the invention is to completely eliminate this defect while retaining the primary quality of a good
Has a boom handle - its high lateral rigidity - thanks to an integrated and compact articulation allowing fixing at variable angle to the mast, in the desired position.
La figure 1 montre la poignée de wishbone A vue de dessus avec son berceau B en position "déclipsée" pour une meilleure compréhension du système. Figure 1 shows the wishbone handle A seen from above with its cradle B in the "unclipped" position for a better understanding of the system.
La figure 2 montre une coupe simplifiée de la figure 1, les deux pièces A et B étant déclipsées. Figure 2 shows a simplified section of Figure 1, the two parts A and B being unclipped.
Les caractéristiques essentielles de l'invention sont les suivantes - un axe d'articulation (x) horizontal par rapport au mât contenu dans le plan du wishbone - le clipsage du berceau B sur la poignée A en son milieu, formant une articulation ; - le clipsage serré du logement 2 du berceau B sur le pivot 1 volontairement long, de la poignée A - les faces 3 et 4 de la poignée A sont en contact forcé contre les faces 5 et 6 du berceau B. The essential characteristics of the invention are as follows - a hinge axis (x) horizontal with respect to the mast contained in the plane of the boom - the clipping of the cradle B on the handle A in the middle, forming a hinge; - the tight clipping of the housing 2 of the cradle B on the deliberately long pivot 1 of the handle A - the faces 3 and 4 of the handle A are in forced contact against the faces 5 and 6 of the cradle B.
- les parties 7 et 8 du berceau B peuvent dans les positions ex trêmes rentrer en contact avec les parties 9 ou 10 de la poignée
A, ce qui a pour but une plus grande facilité d'emploi. - the parts 7 and 8 of the cradle B can in the extreme positions come into contact with the parts 9 or 10 of the handle
A, which aims for greater ease of use.
- le berceau B peut varier de part et d'autre de la poignée A de O à + 120 et de O à - 120 ce qui permet une utilisation de poignée aussi bien dans un sens que dans l'autre.- the cradle B can vary on either side of the handle A from O to + 120 and from O to - 120 which allows the use of a handle both in one direction and in the other.
- la partie 15 du berceau B représente le logement du mat (ce dernier n' étant pas dessiné).- Part 15 of the cradle B represents the housing of the mat (the latter not being drawn).
La description qui suit ne concerne pas l'invention mais permet une meilleure compréhension du système : - le crochet 11 est en position semi-fermée et permet de tendre le cable 12, - la boucle du câble 12 s'accroche au point 13 après avoir entouré le mât (ce dernier ne figurant pas sur le plan), - les tubes 14 et 14' du wishbone sont emboités dans la poignée. The description which follows does not relate to the invention but allows a better understanding of the system: - the hook 11 is in the semi-closed position and makes it possible to tension the cable 12, - the loop of the cable 12 hooks at point 13 after having surrounded the mast (the latter not shown on the plan), - the tubes 14 and 14 'of the wishbone are fitted in the handle.
