Abstract

The invention relates to the conversion of a basic sailboard, such as a "fun board", into any other kind of sailboard, so allowing it to be used for many purposes. The basic sailboard A is able to accommodate a rear portion B which is pushed inside it, this action being reinforced by male or female inserts I contained inside A and B. The rear portion B is immobilised in the forward direction by a stop C belonging to the basic float, the joint being completed by a seal of an elastic material. The assembly is made nondissociable in use by means of bolts symbolised by arrows. The sailboard of the invention is intended to alleviate the unpredictability of the weather (wind, waves) and has the advantage of compactness and of being less expensive than several different sailboards.

Description

La présente invention concerne la transfo'r tion d'un f teur 'I de base du type (tFUN BOARD, ou tout autre type en FUN BOARD poiyvalent, ou en planche de Régate, ou en planche d'initiation. The present invention relates to the transfer of a base f ector of the type (tFUN BOARD, or any other type into a multi-purpose FUN BOARD, or a regatta board, or an initiation board.

Elle permet également de changer le type d'asymétrie d'une planche à voile pour vagues. It also allows you to change the type of asymmetry of a windsurfing board for waves.

Il faut savoir, en effet, qu'à chaque degré de pratique, et qu'a' chaque type de temps (vent, vagues...) correspond un type de plache différent. Ainsi, une seule planche à voile est insuffisante en fonction, d'une part de la progression leehnique du pratiquant, d'autre part, des caprices de la météorologie. La possession de plusieurs planches à voile est onéreuse et leur transport, ainsi que leur stockage contraignants. You should know, in fact, that at each level of practice, and that 'each type of weather (wind, waves ...) corresponds to a different type of plache. Thus, a single windsurfing board is insufficient depending, on the one hand, on the leehnic progression of the practitioner, on the other hand, on the whims of meteorology. The possession of several windsurfing boards is expensive and their transport, as well as their storage constraining.

La planche à voile faisant l'objet-de la présente invention pallie ces inconvénients majeurs, puisqu'elle est composée d'un flotteur de base pouvant accueillir différentes rallonges en forme de queue de planche à voile lui conférant les types d'utilisation désirés, sans altérer l'aérodynamisme ni la rigidité, caractérisant une planche classique, c'est-à-dire d'un seul morceau. The windsurfing object of the present invention overcomes these major drawbacks, since it is composed of a basic float that can accommodate different extensions in the form of a windsurfing tail giving it the desired types of use, without altering aerodynamics or rigidity, characterizing a classic board, that is to say of a single piece.

La présente invention concerne l'adaptation d'une ou plusieurs rallonges de queue de planche à voile sur le flotteur de base préparé à cet effet. The present invention relates to the adaptation of one or more windsurfing tail extensions on the basic float prepared for this purpose.

Les avantages et caractéristiques de la présente invention ressortiront mieux à la lecture de la description qui va suivre, faite en regard des figures données à titre indicatif et nuilement limitatif parmi les lesquelles - La figure 1 est une vue de dessus du flotteur de base A et d'une partie arrière B, en forme de queue de planche à voile, non assemblés. Sur cette figure apparaît le rétrécissement brusque en C de tout le volume arrière du flotteur de base A (sans respecter les proportions qui pourraient nuire à la clarté du dessin) dégageant un espace tel qu'il puisse accueillir, par emboîtement, la partie arrière
B sans discontinuité en C. Sur le dessin de la partie B apparaît en pointillés, le volume E aménagé où vient s'ajuster la partie rétrécie du flotteur A.The advantages and characteristics of the present invention will emerge more clearly on reading the description which follows, made with reference to the figures given for information only and slightly limiting among which - FIG. 1 is a top view of the basic float A and a rear part B, in the shape of a windsurfing tail, not assembled. In this figure appears the abrupt narrowing in C of all the rear volume of the basic float A (without respecting the proportions which could harm the clarity of the drawing) freeing up a space such that it can accommodate, by interlocking, the rear part
B without discontinuity in C. In the drawing of part B appears in dotted lines, the volume E arranged where the narrowed part of the float A comes to fit.

- La figure 2 est une vue de profil en coupe ZZ' des deux parties
A et B non assemblées, où apparaissent, à nouveau, le rétrécissement de l'arrière de A, la butée C et l'évidement E de la partie B, tel qu'il puisse accueillir I 'arrière de la planche de base A, par emboî tement - La figure 3 montre le détail en C en coupe ZZ' des parties A et
B assemblées. Elle met en évidence le raccordement, sans discontinuité et l'ajustement parfait des parties A et B en C. Sur la figure 3 et sur le reste de la surface d'emboîtement, apparaît également le joint J en matière élastique, solidaire de l'une ou l'autre partie
A ou B, destiné à parfaire le raccordement et à empêcher la pénétration d'eau et de corps étrangers.- Figure 2 is a profile view in section ZZ 'of the two parts
A and B not assembled, where, once again, the narrowing of the rear of A, the stop C and the recess E of the part B appear, so that it can accommodate the rear of the base board A, by interlocking - Figure 3 shows the detail in C in section ZZ 'of parts A and
B assembled. It highlights the connection, without discontinuity and the perfect adjustment of parts A and B at C. In FIG. 3 and on the rest of the interlocking surface, also appears the seal J made of elastic material, integral with the either party
A or B, intended to perfect the connection and to prevent the penetration of water and foreign bodies.

Sur la figure 3 apparaît aussi -In système de verrouillage, constituant un exemple, et un exemple; seulement de verrouillage, celui-ci pouvant être effectué en un ou plusieurs points de l'emboîtement.In Figure 3 also appears -In locking system, constituting an example, and an example; only locking, it can be performed at one or more points of the socket.

La mise en oeuvre de ce verrouillage, pour une utilisation aisée, doit être rapide. The implementation of this locking, for easy use, must be rapid.

L'exemple choisi, pour la figure 3, est une vis à pas rapide. The example chosen for FIG. 3 is a fast-pitch screw.

- La figure 4 est une coupe transversale des parties A et B non assemblées et montre un renforcement possible de l'assemblage, par l'installation d'un ou plusieurs inserts I mâles et femelles, respectivement ou non respectivement, dans les parties A et B. Ces inserts sont réalisés en des matériaux légers et résistants à la flexion et au cisaillement. Le duralumin ou des résines synthétiques peuvent 5 5 illustre le fait que les inserts sont placés à mi-épais- seur, à l'arrière du flotteur de base A. Les inserts (mâles ou femel- les) correspondants, dans ia partie B, sont placés de même.- Figure 4 is a cross section of the unassembled parts A and B and shows a possible reinforcement of the assembly, by the installation of one or more male and female inserts I, respectively or not respectively, in parts A and B. These inserts are made of light materials which are resistant to bending and shearing. Duralumin or synthetic resins can illustrate the fact that the inserts are placed at mid-thickness, behind the base float A. The corresponding inserts (male or female), in part B, are placed in the same way.

- La figure 6 est une vue de dessus, représentant l'arrière de la partie A et, en pointillés, les inserts I dans lesquels viennent s'introduire des caches inserts K, formés de telle sorte qu'ils complètent le profil de l'arrière de la partie A, afin de lui restituer un profil aérodynamique parfait. - Figure 6 is a top view, representing the rear of part A and, in dotted lines, the inserts I into which are inserted insert covers K, formed so that they complete the profile of the rear of part A, in order to restore it to a perfect aerodynamic profile.
