Abstract
The coupling is placed between the wishbone (7) and mast (2) of a sail board. It consists of a V shaped piece (8), pivoted (9) on both of the wishbone arms. These hold the mast when sail force acts on the wishbone. The wishbone arms each have seatings (10) which are intended to receive pivots carried by the V shaped part. The V shaped part is covered with a protecting cord of synthetic rubber (13). The seatings are open grooves and sail force prevents the pivots from leaving these grooves.
Description
"Dispositif de liaison entre wishbone et mât de planche à voile" La présente invention concerne un dispositif de liaison entre wishbone et mât de planche à voile.
En général, la tête du wishbone est fixée au mât à l'aide d'un cordage. Une extrémité de celui-ci est fixée au mât par un noeud de cabestan, lequel est suivi de deux tours morts puis d'un transfilage au travers d'un ou plusieurs trous prévus à cet effet dans la tête du wishbone. L'autre extrémité dudit cordage est ensuite soit frappée sur un taquet, soit assujettie dans un coïnceur porté par un bras du wishbone.
Ce mode de fixation traditionnel rend malaisé le réglage en hauteur du wishbone, réglage nécessaire tant en ce qui concerne la taille de l'utilisateur que les conditions de vent.
La présente invention a pour but de fournir une solution à ce problème. A cet effet, un dispositif de liaison entre wishbone et mât de planche à voile conforme à l'invention consiste en un élément substantiellement en forme de V, pivoté sur chacun des deux bras du wishbone et destiné à enserrer le mât lors de l'étarquage du point d'écoute de la voile sur ledit wishbone.
Pour plus de clarté, un exemple de réalisation de l'invention est décrit ci-après avec référence aux dessins annexés, dans lesquels :
la figure 1 représente schématiquement une planche à voile et sert à localiser le dispositif selon l'invention; la figure 2 est une vue perspective, à échelle agrandie, de la partie indiquée en F2 à la figure 1; la figure 3 représente, en perspective, la pièce de liaison en V constituant l'élément principal de l'invention; et la figure 4 est une vue en plan du dispositif représenté à la figure 2.
La planche à voile représentée à la figure 1 est constituée par un flotteur 1 auquel est solidarisé de façon amovible un mât articulé 2 autour duquel est engagé le fourreau 3 d'une voile 4. Le point d'amure 5. de la voile 4 est étarqué sur le pied du mât
<EMI ID=1.1>
d'un wishbone 7 dont l'autre extrémité est reliée de façon pivotante au mât 2.
La liaison entre le wishbone 7 et le mât 2 s'effectue, con-fermement à l'invention, à l'intervention d'un élément 8 substantiellement en forme de V, pourvu de deux tétons latéraux 9. Ces derniers sont destinés à être engagés, chacun, dans une rainure 10 prévue à cet effet dans un blocket 11, ces blockets étant soli-
<EMI ID=2.1>
L'élément 8, engagé au travers de l'échancrure 12 usuelle de la voile 4, est destiné à venir enserrer le mât lorsque le point d'écoute 6 est étarqué sur le wishbone 7. Cet étarquage empêche que les tenons 9 sortent des rainures 10.
On remarque que la hauteur d'application de l'élément 8 sur le mât 2 peut être aisément modifiée en fonction de la taille du pilote et/ou des conditions du vent.
L'élément 8 peut être avantageusement pourvu d'un revêtement protecteur 13, par exemple en caoutchouc synthétique, téflon ou similaire.
REVENDICATIONS.
1.- Dispositif de liaison entre wishbone et mât de planche à voile, caractérisé en ce qu'il consiste en un élément substantiellement en forme de V, pivoté sur chacun des deux bras du wishbone et destiné à enserrer le mât lors de l'étarquage du point d'écoute de la voile sur ledit wishbone.
"Connection device between wishbone and windsurf mast" The present invention relates to a connection device between wishbone and windsurf mast.
In general, the head of the wishbone is fixed to the mast using a rope. One end of the latter is fixed to the mast by a capstan knot, which is followed by two dead turns and then by threading through one or more holes provided for this purpose in the head of the wishbone. The other end of the said rope is then either struck on a cleat, or secured in a wedge carried by an arm of the wishbone.
This traditional method of attachment makes it difficult to adjust the height of the boom, which is necessary both in terms of user size and wind conditions.
The present invention aims to provide a solution to this problem. To this end, a connecting device between wishbone and windsurf mast according to the invention consists of a substantially V-shaped element, pivoted on each of the two arms of the wishbone and intended to grip the mast during towing from the listening point of the sail on said wishbone.
For greater clarity, an exemplary embodiment of the invention is described below with reference to the accompanying drawings, in which:
Figure 1 schematically shows a windsurfing board and is used to locate the device according to the invention; Figure 2 is a perspective view, on an enlarged scale, of the part indicated in F2 in Figure 1; Figure 3 shows, in perspective, the V-shaped connecting piece constituting the main element of the invention; and FIG. 4 is a plan view of the device shown in FIG. 2.
The windsurfing board shown in FIG. 1 is constituted by a float 1 to which a hinged mast 2 is removably secured around which the sheath 3 of a sail 4 is engaged. The tack point 5. of the sail 4 is stretched on the foot of the mast
<EMI ID = 1.1>
a wishbone 7, the other end of which is pivotally connected to the mast 2.
The connection between the wishbone 7 and the mast 2 takes place, con-firmly with the invention, with the intervention of an element 8 substantially in the form of a V, provided with two lateral pins 9. The latter are intended to be each engaged in a groove 10 provided for this purpose in a blocket 11, these blockets being solid
<EMI ID = 2.1>
The element 8, engaged through the usual notch 12 of the sail 4, is intended to grip the mast when the listening point 6 is tightened on the wishbone 7. This tightening prevents the studs 9 from coming out of the grooves 10.
It is noted that the height of application of the element 8 on the mast 2 can be easily modified according to the size of the pilot and / or the wind conditions.
The element 8 can advantageously be provided with a protective coating 13, for example made of synthetic rubber, Teflon or the like.
CLAIMS.
1.- Connecting device between wishbone and windsurf mast, characterized in that it consists of a substantially V-shaped element, pivoted on each of the two arms of the wishbone and intended to grip the mast during towing from the listening point of the sail on said wishbone.
