Abstract

The hull can transform a windsurf board into a catamaran. The board has two shells (1,2) which are mirror images and form the board when assembled. The two shells are retained together by fastenings, but can be released and retained parallel to one another by a deck (20) to form a catamaran. The two shells may be rotated through 90 degrees between their connected and separated positions. The fastenings can be formed by inserts with double flanges engaging in shaped apertures in the boards.

Description

L'invention concerne une embarcation pouvant être transformée alternativement en planche à voile (wind surf) et en catamaran.The invention relates to a boat which can be transformed alternately into windsurfing (wind surfing) and catamaran.

Les planches à voile et les catamarans sont bien connus, en tant qu'embarcations indépendantes chacune prévue pour un propre emploi spécifique et avec une propre structure particulière, de sorte que l'usager doit nécessairement se pourvoir d'une embarcation différente selon l'emploi désiré, ce qui comporte pour lui des charges non indifférentes pour l'acquisition, ainsi qu'un encombrement consi dérable pour les mettre à l'abri et des difficultés lorsqu'il désire changer d'embarcation.Windsurfing boards and catamarans are well known as independent boats, each intended for its own specific use and with its own particular structure, so that the user must necessarily have a different boat depending on the job. desired, which involves for him non-indifferent charges for the acquisition, as well as a considerable space to shelter them and difficulties when he wishes to change boat.

L'invention se propose par conséquent de réaliser une embarcation pouvant servir, par des opérations simples et rapides, soit de planche à voile (wind surf), soit de catamaran et en affectant la structure et les fonctions de l'une ou de l'autre.The invention therefore proposes to produce a boat which can be used, by simple and rapid operations, either for windsurfing (wind surfing) or for a catamaran and by affecting the structure and the functions of one or the other.

L'invention prévoit dans ce but deux coques de for me réciproquement spéculaire pouvant être assemblées de façon coplanaire entr'elles et reliées par des moyens quelque ce soit aptes à cette tâche, de sor te à réaliser une planche à voile dont chacune des coques représente une moitié longitudinale, ou bien disposées parallèlement entr'elles et à une certai ne distance et reliées au moyen d'une structure d' entretoisement quelque ce soit interposée de sorte à réaliser un catamaran.To this end, the invention provides two reciprocally specular shaped shells which can be assembled in a coplanar manner with one another and connected by means whatever it is suitable for this task, so as to make a windsurfing board each of whose hulls represents a longitudinal half, or else arranged parallel to one another and to a certain distance and connected by means of a structure of bracing whatever is interposed so as to achieve a catamaran.

L'assemblage desdites deux coques dans leur juste position pour obtenir une planche à voile est obte nu, suivant l'invention, de préférence avec des moyens d'emboîtement et, en particulier, en faisant usage de goujons à emboîtement à double queue d'aronde.The assembly of said two hulls in their correct position to obtain a windsurf board is obtained naked, according to the invention, preferably with interlocking means and, in particular, by making use of interlocking studs with double tail of dovetails.

L'assemblage desdites deux coques dans leur juste position pour obtenir un catamaran est obtenu, toujours suivant l'invention, en disposant celles-ci en profil après les avoir renversées de 90° sur leurs axes longitudinaux par rapport à la position coplanaire de la planche à voile.The assembly of said two hulls in their correct position to obtain a catamaran is obtained, still according to the invention, by arranging them in profile after having overturned them by 90 ° on their longitudinal axes relative to the coplanar position of the board. sailing.

Toujours suivant l'invention, la structure transver sale d'entretoisement et de reliage des deux coques dans leur position entretoisée dans le catamaran est constituée de préférence par une ou deux branches transversale étant elles aussi de préférence emboîtées sur les coques en queue d'aronde et en faisant usage des mêmes entailles prévues pour l'assemblage réciproce des coques pour la planche à voile.Still according to the invention, the dirty cross-bracing and bridging structure of the two hulls in their braced position in the catamaran preferably consists of one or two transverse branches which are also preferably fitted tees on the dovetail hulls and using the same notches provided for the reciprocal assembly of the hulls for windsurfing.

Enfin , toujours suivant l'invention, une patte in clinée, en matériel quelque ce soit, est fixée en proximité de l'extrémité antérieure de chaque coque, du côté extérieur de celles-ci,les pattes fournissent u ne poussée dynamique vers le haut lorsque la partie antérieure de la coque se plonge dans l'eau. La rai son doit être recherchée dans le fait que la quantité de mouvement de l'eau qui frappe le plan incliné (patte) change en direction. La différence vectoriel le entre la quantité de mouvement finale et la quan tité de mouvement initiale de l'eau indique la di - rection de la force ayant une composante vers le haut.Finally, still according to the invention, an inclined leg, in whatever material, is fixed in proximity to the anterior end of each shell, on the outside of these, the legs provide a dynamic upward push. when the front part of the hull plunges into the water. The reason must be sought in the fact that the amount of movement of the water hitting the inclined plane (leg) changes in direction. The vector difference between the final momentum and the initial amount of movement of the water indicates the direction of the force with an upward component.

Sur les figures on a indiqué avec 1, 2 les coques constituant les deux moitiés d'une planche à voile (wind surf) et qui sont spéculaires entr'elles par rapport au plan longitudinal médian de la planche à voile. Lorsque les deux coques 1, 2 sont en position coplanaire et placées côte à côte, elles forment une planche à voile 3 (fig.1). Les deux coques 1, 2 sont assemblées dans ce cas au moyen de goujons 4, 5, 6, 7 d'emboîtement à double queue d'aronde.The figures show with 1, 2 the hulls constituting the two halves of a wind surfboard and which are specular to each other with respect to the median longitudinal plane of the windsurf board. When the two hulls 1, 2 are in the coplanar position and placed side by side, they form a windsurf board 3 (fig.1). The two shells 1, 2 are assembled in this case by means of studs 4, 5, 6, 7 double dovetail fitting.

Un tel goujon 4 est représentée en échelle agrandie sur la figure 5, affectant la forme d'un "X", c'est à dire un profil à double queue d'aronde qui est constitué par deux profils à queue d'aronde assem= blés en correspondance de leurs côtés plus courts. Chacun desdits goujons 4, 5, 6; 7 est emboîté par moitié dans une correspondante entaille à queue d'a ronde 104, 105, 106, 107 prévue dans la coque 1, tandis que l'autre moitié est emboîtée dans une correspondante entaille en queue d'aronde 204, 205, 206, 207 prévue dans l'autre coque 2. Les coques 1, 2 sont ainsi serrées et assemblées entr'elles.Such a stud 4 is shown in enlarged scale in FIG. 5, affecting the shape of an "X", that is to say a double dovetail profile which is constituted by two dovetail profiles assem = wheat in correspondence of their shorter sides. Each of said studs 4, 5, 6; 7 is fitted in half in a corresponding notch with a round tail 104, 105, 106, 107 provided in the shell 1, while the other half is fitted in a corresponding notch in dovetail 204, 205, 206 , 207 provided in the other shell 2. The shells 1, 2 are thus clamped and assembled between them.

Par ailleurs, au moins une partie de ces goujons d'emboîtement à double queue d'aronde 4, 5, 6, 7 peut être pourvue d'une agrafe supérieure et d'une agrafe inférieure 8 qui sont reliées au goujon par une longue vis 9 passant à travers le goujon et les agrafes. Les extrémités des agrafes sont sailIan tes des deux côtés par rapport au goujon et sais sent de leurs dents des entailles correspondantes prévues dans les coques 1, 2 de sorte à serrer cel les-ci entr'elles en coopération avec les embolte= ments.Furthermore, at least part of these double dovetail interlocking studs 4, 5, 6, 7 can be provided with an upper clip and a lower clip 8 which are connected to the stud by a long screw. 9 passing through the stud and staples. The ends of the staples are sailIan tes on both sides relative to the stud and know feels their teeth of the corresponding notches provided in the shells 1, 2 so as to tighten them between them in cooperation with the embolte = ments.

Les goujons d'emboîtement en double queue d'aronde sont employés aussi pour l'application d'autre par ties de fonctionnement de la planche à voile 3.Dans la forme de réalisation suivant la figure 1, le mât 10, la dérive 11 et la nageoire postérieure 12 de la planche à voile sont fixés à autant de goujons d'emboîtement 4, 5, 6, 7 en double queue d'aronde.Double dovetail studs are also used for the application of other operating parts of the windsurfing board 3. In the embodiment according to FIG. 1, the mast 10, the fin 11 and the rear fin 12 of the windsurf board are fixed to as many interlocking studs 4, 5, 6, 7 in double dovetail.

Outre à l'assemblage pour réaliser la planche à voile 3, les deux coques 1, 2 peuvent être assem = blées aussi pour réaliser un catamaran 13 tel que représenté sur la figure 4. Les deux coques 1 et 2 formant la planche à voile 3 sont à cet effet sépa rées en détachant les goujons d'emboîtement 4, 5, 6, 7. Successivement les deux coques 1, 2 sont pla cées de profil à une certaine distance, c'est à dire en renversant chacune d'elles de 90° sur son axe longitudinal, en dehors, de sorte à lui faire présenter vers le haut sa surface jadis intérieure,pourvue des entailles à queue dtaronde 104, 105, 106, 107 et 204, 205, 206, 207 (fig. 3). Pour réaliser le catamaran 13, les deux coques 1, 2 sont reliées entr'elles par deux branches transversales 15 et 17 qui affectent un profil à queue d'aronde et qui sont emboîtées dans deux entailles à queue d'aronde correspondantes et alignées 105, 205 et 107, 207 des deux coques 1, 2, c'est à dire les mêmes dans lesquelles les goujons 5, 7 en double queue d'a= ronde étaient emboîtés lors de l'assemblage des coques en planche à voile. Dans le but d'éviter que les branches 15, 17 puissent sortir de leurs emboîtements, les coques 1, 2 sont serrées l'une à l'autre par des câbles en acier 16 pourvus de ten= deurs 116, chacune des extrémités des câbles étant reliée à une des coques 1, 2. Les extrémités des câbles sont à cet effet pourvues d'équerre-support 18 chacune desquelles est fixée à la coque 1, re = spectivement 2 en les faisant passer par exemple dans les entailles 105, 205 et 107, 207 au dessous des branches 15, 17. Pour tendre le câble 16 Qn place celui-ci sur un pont 19 qui peut être appli= qué au dessous de la branche 15 et, respectivement, de la branche 17.In addition to the assembly for producing the windsurfing board 3, the two hulls 1, 2 can also be assembled to make a catamaran 13 as shown in FIG. 4. The two hulls 1 and 2 forming the windsurfing board 3 are for this purpose separated by detaching the interlocking studs 4, 5, 6, 7. Successively the two shells 1, 2 are placed in profile at a certain distance, that is to say by inverting each of them 90 ° about its longitudinal axis, outwards, so as to make it show up its formerly inner surface provided with indentations to tail t dovetail 104, 105, 106, 107 and 204, 205, 206, 207 (fig. 3). To make the catamaran 13, the two hulls 1, 2 are interconnected by two transverse branches 15 and 17 which affect a dovetail profile and which are fitted into two corresponding and aligned dovetail notches 105, 205 and 107, 207 of the two shells 1, 2, that is to say the same in which the studs 5, 7 in double tail of a = round were nested when assembling the hulls in windsurfing. In order to avoid that the branches 15, 17 can come out of their sockets, the shells 1, 2 are tightened to each other by steel cables 16 provided with tenors 116, each of the ends of the cables being connected to one of the shells 1, 2. The ends of the cables are for this purpose provided with support brackets 18 each of which is fixed to the shell 1, re = spectively 2 by passing them for example through the notches 105, 205 and 107, 207 below the branches 15, 17. To tension the cable 16 Q n place it on a bridge 19 which can be applied = below the branch 15 and, respectively, of the branch 17.

En correspondance de la surface comprise entre les deux coques longitudinales 1, 2 et les deux branches transversales 15, 17, une toile peut être tendue, ou bien une plate-forme 20 peut être prévue, cette dernière pouvant être constituée par des panneaux rigides remplis avec du polystyrène et emboîtés l'un dans l'autre et dans les deux branches transversales de sorte à former un plan rigide sur lequel l'usager peut se tenir debout. Le catamaran 13 est gouverné par des gouvernails 21 en soi connus.In correspondence of the surface between the two longitudinal shells 1, 2 and the two transverse branches 15, 17, a fabric can be stretched, or else a platform 20 can be provided, the latter can be constituted by rigid panels filled with polystyrene and nested one inside the other and in the two transverse branches so as to form a rigid plane on which the user can stand. The catamaran 13 is governed by rudders 21 known per se.

Le même mât 10 de la planche à voile est employé comme mât 110 du catamaran 13, une pièce pouvant être adjointe par emboîtement. La bôme de la plan che à voile 3 peut être aussi utilisée pour le ca tamaran 13. Lorsqu'on veut gouverner le catamaran 13 en guise de planche à voile il faut pouvoir in cliner le mât de la position verticale dans une autre direction quelque ce soit ainsi qu'on le fait sur la planche à voile 3, ce qui impose la présence d'un joint à rotule. Lorsqu'on ne veut pas gouverner le catamaran de cette façon, son mât 110 est maintenu en position droite par exemple au moyen de deux haubans hauts, de deux haubans bas et de deux étais, ou bien par un seul étai pour le cas où on désire faire usage d'un foc. On peut aussi prévoir pour le catamaran 13 un mât appro = prié avec bôme respective et une voilure appro = priée.The same mast 10 of the windsurfing board is used as the mast 110 of the catamaran 13, a part which can be joined by interlocking. The boom of the sail board 3 can also be used for the tamaran 13. When you want to govern the catamaran 13 as a windsurf board, you must be able to tilt the mast from the vertical position in another direction whatever either as is done on the windsurf board 3, which requires the presence of a ball joint. When one does not want to govern the catamaran in this way, its mast 110 is maintained in an upright position for example by means of two high shrouds, two low shrouds and two stays, or else by a single stay in the case where one wish to use a jib. One can also provide for catamaran 13 an appropriate = required mast with respective boom and an appropriate = required wing.

Dans le but de fournir au catamaran 13 une poussée dynamique vers le haut lorsque la partie antérieure des coques se plonge dans l'eau, l'invention a pré vu l'application d'une patte inclinée 123, 223 en correspondance de l'extrémité de chaque coque, du côté extérieur de celle-ci. Sur la figure 6 on a montré une patte à droite 123 et une patte à gauche 223 qui sont fixées sur des supports inclinés 121, 221 au moyen de rivets R aux parties inclinées 122, 222 moulées en une seule pièce avec lesdits supports 121, 221. Il a été établi par l'expérience que l'inclination des pattes 123, 223 est particulièr = ment fonctionnelle si établie en 30°. Les supports 121, 221 présentent des rainures 121', 221' au moyen desquelles ils sont appliqués sur les chevilles 120, 220 des coques 1, 2 de sorte que les pattes 123, 223 sont disposées du côté extérieur de cel = les-ci.In order to provide the catamaran 13 with a dynamic upward thrust when the front part of the hulls is immersed in water, the invention provided for the application of an inclined tab 123, 223 corresponding to the end of each shell, on the outer side thereof. FIG. 6 shows a right tab 123 and a left tab 223 which are fixed on inclined supports 121, 221 by means of rivets R with inclined parts 122, 222 molded in one piece with said supports 121, 221. It has been established by experience that the inclination of the legs 123, 223 is particularly functional if established in 30 °. The supports 121, 221 have grooves 121 ', 221' by means of which they are applied to the pegs 120, 220 of the shells 1, 2 so that the tabs 123, 223 are arranged on the outside of the latter.

Bien entendu l'invention n'est pas limitée au formes de réalisation qui ont été décrites ci-avant; des modifications pourront être apportées en disposition, proportions et dimensions. Les coques peuvent être réalisées avec un matériel quelque ce soit et affec ter une forme quelconque. D'autre moyen d' emboîte= ment pourront être adoptés soit pour assembler les coques dans le but de réaliser une planche à voile (wind surf), soit pour réaliser un catamaran. On peut prévoir bien entendu toute sorte d'accessoire apte au fonctionnement de la planche à voile et du catamaran, sans pour cela sortir du cadre de l'in= vention.Of course, the invention is not limited to the embodiments which have been described above; modifications may be made in layout, proportions and dimensions. The hulls can be made with any material whatsoever and take on any shape.
