Description

Perfectionnements au flotfceur de planche à voile libre catamaran utilisable également en dériveu . Improvements to the catamaran free windsurfing float can also be used in dinghies.
L'invention concerne un flotteur de forme catamaran utilisable en planche à voile libre ou en dériveur par adjonction d'éléments modulaires.The invention relates to a catamaran-shaped float usable in free windsurfing or dinghy sailing by the addition of modular elements.
On connaît déjà des catamarans sur lesquels on a monté un gréément à voile libre tel que décrit dans les brevets français n° 2 436 709 et 2 451 709. Ces embarcations sont lourdes et ne sont pas facilement manipulables avec un gréément libre. En effet, il est difficile pour des débutants ou des véliplanchistes moyens de virer avec de tels engins comme on le fait avec une planche à voile libre (PAVL) traditionnelle, à cause de l'effet de rails produit par les deux coques. De plus ces engins ne sont pas tr-ansportables sur le toit de véhicules de tourisme.Catamarans are already known on which a free sail rigging has been mounted as described in French patents Nos. 2,436,709 and 2,451,709. These boats are heavy and cannot be easily handled with a free rigging. Indeed, it is difficult for beginners or average windsurfers to tack with such gear as is done with a traditional free windsurf (PAVL), because of the effect of rails produced by the two hulls. In addition, these devices are not very portable on the roof of passenger vehicles.
Les perfectionnements selon l'invention ont pour objet: d'accroître la maniabilité à toutes les allures et la facilité de conduite notamment pour les virements. Selon une première réalisation de l'invention, l'arrière de chaque coque est prévu pour recevoir un safran équipé d'un mécanisme de rappel élastique les maintenant au repos dans l'axe du flotteur, coopérant avec une barre commandée au pied; d'alléger le flotteur par remplissage de mousse uniquement dans le volume du pont, de fournir les pièces annexes suivantes pour transformer ledit flotteur de PAVL en dériveur:The object of the improvements according to the invention is: to increase the maneuverability at all speeds and the ease of driving, in particular for transfers. According to a first embodiment of the invention, the rear of each hull is designed to receive a rudder equipped with an elastic return mechanism keeping them at rest in the axis of the float, cooperating with a bar controlled by the foot; to lighten the float by filling with foam only in the volume of the deck, to supply the following additional parts to transform said PAVL float into a dinghy:
- un support amovible de mât fixe incluant une plaque de répartition d'efforts évitant le haubannage; - deux rails supplémentaires sur le dessus de chaque coque à l'arrière du pont;- a removable fixed mast support including a force distribution plate avoiding the bracing; - two additional rails on top of each hull aft of the deck;
- un pivot de barre en cas d'utilisation des deux safrans.- a bar pivot when using the two rudders.
Il est également prévu un équipement pour recevoir un ensemble de propulsion à hélice, et un chariot de transport à deux roues se montant sur les paliers de safrans.Equipment is also provided for receiving a propeller propulsion unit, and a two-wheeled transport carriage mounted on the rudder bearings.
Selon une seconde réalisation de l'invention, la position du pont a été reculée au maximum pour permettre à l'utilisateur d'effectuer toutes ses manoeuvres de l'arrière, évitant ainsi de passer devant le mât, le pont a été surélevé, les deux coques sont moins larges et leur bordure extérieure comporte une partie en surplomb au-dessus de la ligne de flottaison, de largeur dégressive de l'arrière vers l'avant, on a également ajouté des cale-pied; le dessous des deux coques s'élève progressivement en légère courbe de l'arrière vers l'avant jusqu'à leur extrémité qui se situe au-dessus de la ligne de flottaison, de plus, le dessous des deux coques présente, en section, une forme creuse à grand rayon et ce sur toute leur longueur.According to a second embodiment of the invention, the position of the bridge has been moved back as far as possible to allow the user to carry out all his maneuvers from the rear, thus avoiding passing in front of the mast, the deck has been raised, the two hulls are narrower and their outer edge has an overhanging part above the waterline, of tapering width from the rear to the front, we also added toe clips; the underside of the two hulls rises gradually in a slight curve from the rear towards the front to their end which is located above the waterline, in addition, the underside of the two hulls is present in section, a hollow shape with a large radius and this over their entire length.
Les avantages apportés par les perfectionnements selon l'invention sont les suivants:The advantages brought by the improvements according to the invention are the following:
- amélioration de la maniabilité en virage à toutes les allures, particulièrement pour les débutants et les véliplanchistes moyens notamment par adjonction de safrans commandés par une barre manoeuvrée au pied;- improved maneuverability when cornering at all speeds, particularly for beginners and medium windsurfers, in particular by adding rudders controlled by a foot-operated bar;
- accroissement de la rapidité d'apprentissage grâce à la stabilité exceptionnelle excluant les chutes et notamment par la possibilité d'accompagnement par un moniteur; - impossibilité de chavirer conférant une grande sécurité; la voile affalée, le flotteur constitue un canot insubmersible sur lequel on peut s'arrimer par gros temps;- increase in the speed of learning thanks to the exceptional stability excluding falls and in particular by the possibility of accompaniment by an instructor; - impossibility of capsizing conferring great security; with the sail collapsed, the float constitutes an unsinkable canoe on which you can stow in bad weather;
- légèreté du flotteur qui n'est rempli de mousse que dans le volume du pont; - utilisations polyvalentes en PAVL et en dériveur;- lightness of the float which is only filled with foam in the volume of the deck; - versatile uses in PAVL and dinghy;

Les fig.l et 2 montrent, en élévation et en vue de dessus, un exemple de flotteur monobloc utilisable en PAVL ou en dériveur suivant les accessoires utilisés. Il se compose de deux coques 1,2 identiques ou pouvant être symétriques, solidaires d'un pont 3 disposé largement au-dessus de la ligne de flottaison 4. il est réalisé en deux parties en polyester ou en matière plastique thermoformable de caractéristiques compatibles, collées sur un plan de joint 5 fig.3 vu de l'arrière. Sur toute la longueur du pont, la partie inférieure 6 vient se raccorder sur le plan de joint extérieur 5A en incluant la partie inférieure 7 des coques 1,2. Au-delà des lignes veticales arrières 8 et avant 9, la partie inférieure du flotteur se prolonge en avant et en arrière en s ' interrompant sur les plans de joint horizontaux 5A,5B pour chaque coque 1,2. La largeur 10 des coques , au niveau du plan de joint est identique sur toute la longueur jusqu'à la ligne 12. Depuis 12 débute une forme spatulée qui s'élève jusqu'au- dessus de la ligne de flottaison 4. le volume des coques est sensiblement identique au droit des lignes 12,13, mais s'accroît entre les lignes 8 et 9 sous le pont, puis décroît rapidement après la ligne 12 vers l'avant. Les flancs 15,16 de la coque sont légèrement en pente de l'ordre de 5° et se raccordent avec de petits rayons convexes 17 sur une courbe inférieure 18 à grand rayon pour améliorer la glisse latérale en virage. La partie supérieure 20 du flotteur comporte le dessus du pont, une partie latérale du dessus de chaque coque 1,2 au droit du pont et la totalité du dessus des coques en avant et en arrière du pont jusqu'au plan de joint horizontal supérieur 5A,5B (fig.3) . Les parties supérieures 20 et inférieure 6 du flotteur sont chacune réalisée en un seul morceau. L'avant spatule 21 de chaque coque comporte un bouchon 22 formant crochet de remorquage. Le dessus et le dessous du pont sont en forme légèrement bombée à très grand rayon, le dessous présentant un rayon plus faible pour accroître la rigidité et la résistance aux vibrations. Le dessus du pont comporte un revêtement anti-dérapant; il est équipé normalement d'un rail avant 23 pour recevoir le pied de mât de gréément libre pour l'utilisation en PAVL, ou une emplanture de mât fixe 25 constitué d'une plaque de répartition d'efforts 26 fixée également sur le rail 23 par deux boulons, elle reçoit un tube 27 soudé et éventuellement renforcé par des goussets 28.' Ce tube reçoit le gréément fixe de dériveur sans haubannage. On a prévu également, à l'arrière, également dans l'axe XX' , un rail 30 pour la fixation d'un pivot de barre. Lorsque l'on utilise pas les safrans pour la PAVL, on peut monter des ailerons arrières 31 sur un rail 32 disposé sous l'arrière de chaque coque 1,2; de même, un autre rail inférieur 33 reçoit une dérive réglable en position 34 sous chaque coque. Sur la face arrière de chaque coque, on a fixé des paliers safran 35. Pour faciliter le transport et surtout le rangement après usage, on a prévu en variante la fabrication du flotteur en trois parties: deux coques identiques et un pont de liaison 42 (fig.4) . La forme inférieure des coques est identique à celle des fig.l, 2 et 3. Par contre elle s'arrête au plan de joint inférieur 5A,5B d chaque côté de la coque. La forme supérieure est un pe différente puisqu'elle est plane et se raccorde à son plan d joint horizontal par des rayons 43,44. Comme pour la versio des fig.1,2, 3, on peut remplacer le moussage par un boudin e film plastique extrudé en faible épaisseur, soudé de faço étanche à ses extrémités et mis en place avant assemblage su les plans de joint 5. Une extrémité du boudin, en regard avec le bouchon crochet 22 (fig.1,2) comporte un ajutage de gonflage. Après soudure ou collage du plan de joint, on gonfle les boudins qui prennent leur place en emplissant la totalité du volume interne des coques empêchant l'entrée d'eau en cas de choc perçant la coque. La pression interne de gonflage accroît la résistance élastique de la coque. On peut faire de même pour le pont, mais il est préférable de le remplir de mousse ou d'une structure-légère et très rigide de type nid d'abeille.Fig.l and 2 show, in elevation and in top view, an example of a one-piece float usable in PAVL or dinghy depending on the accessories used. It consists of two identical or possibly symmetrical 1.2 shells, integral with a deck 3 placed widely above the water line 4. it is made in two parts in polyester or in thermoformable plastic material of compatible characteristics, glued on a joint plane 5 fig. 3 seen from the back. Over the entire length of the bridge, the lower part 6 is connected to the external joint plane 5A by including the lower part 7 of the shells 1,2. Beyond the rear vetical lines 8 and front 9, the lower part of the float extends forwards and backwards, interrupting on the horizontal joint planes 5A, 5B for each hull 1,2. The width 10 of the shells, at the joint plane is identical over the entire length up to line 12. From 12 begins a spatula shape which rises above the waterline 4. the volume of the hulls is substantially identical to the right of the lines 12,13, but increases between lines 8 and 9 under the bridge , then decreases rapidly after line 12 forward. The sides 15, 16 of the hull are slightly sloping on the order of 5 ° and are connected with small convex spokes 17 on a lower curve 18 with a large radius to improve lateral gliding when cornering. The upper part 20 of the float comprises the top of the deck, a lateral part of the top of each hull 1, 2 to the right of the deck and the entire top of the hulls in front and behind the deck up to the upper horizontal joint plane 5A , 5B (fig. 3). The upper 20 and lower 6 parts of the float are each made in one piece. The front spatula 21 of each hull has a plug 22 forming a tow hook. The top and bottom of the bridge are slightly domed in shape with a very large radius, the bottom having a smaller radius to increase rigidity and resistance to vibration. The top of the bridge has a non-slip coating; it is normally equipped with a front rail 23 for receiving the free mast foot for use in PAVL, or a fixed mast base 25 consisting of a force distribution plate 26 also fixed on the rail 23 by two bolts, it receives a tube 27 welded and possibly reinforced by gussets 28. ' This tube receives the fixed rigging of a dinghy without shrouding. There is also provided, at the rear, also in the axis XX ', a rail 30 for fixing a bar pivot. When the rudders are not used for the PAVL, rear ailerons 31 can be mounted on a rail 32 disposed under the rear of each hull 1,2; similarly, another lower rail 33 receives an adjustable fin in position 34 under each shell. On the rear face of each hull, rudder bearings 35 have been fixed. In order to facilitate transport and above all storage after use, a variant of the float is provided in three parts: two identical hulls and a connecting bridge 42 ( fig. 4). The lower shape of the shells is identical to that of Figs. 1, 2 and 3. On the other hand, it stops at the lower joint plane 5A, 5B on each side of the hull. The upper shape is a different shape since it is planar and is connected to its horizontal joint plane by spokes 43,44. As for the versio of fig. 1, 2, 3, the foaming can be replaced by a rod of thin extruded plastic film, welded in a sealed manner at its ends and put in place before assembly on the joint surfaces 5. A end of the flange, facing the hook plug 22 (fig.1,2) has an inflation nozzle. After welding or gluing the joint plane, the tubes are inflated which take their place by filling the entire internal volume of the hulls preventing the entry of water in the event of a shock piercing the hull. The internal inflation pressure increases the elastic resistance of the shell. The same can be done for the bridge, but it is preferable to fill it with foam or a light and very rigid structure of honeycomb type.
Sur les fig.5, 6 on a montré en coupe et en vue de dessus, une variante de pont 50, plus large et plus épais, donc plus robuste que celui de la formule PAVL, pour l'utilisation en dériveur avec les mêmes coques 40,41. Comme sur la fig.4, le pont présente dans sa partie interne, des épaulements 51 d'appui et de guidage de mise en place des coques 1,2. Le pont large de dériveur comporte des rails normaux 23,30, mais aussi des rails additifs 52,53 et 54,55 pour recevoir un ensemble de propulsion à hélice comme décrit sur la fig.19. Le pont étroit peut également recevoir ces rails. La coque est munie d'un rail de fixation 60 coopérant avec des moyens complémentaires du pont recevant des boulons 61. Sur la fig.6, on a également représenté, en traits mixtes, le pont étroit de PAVL et son mode de fixation montré en coupe transversale sur la fig.7. La coque 1,2 comporte un logement 65 dans lequel est disposé un rail extrudé 66 en alliage léger en forme de U comportant deux faces d'appui 67 sur un même plan à sa partie supérieure et deux petites ailesIn Figs. 5, 6 we have shown in section and in top view, a variant of deck 50, wider and thicker, therefore more robust than that of the PAVL formula, for use in a dinghy with the same hulls 40.41. As in fig.4, the bridge has in its internal part, shoulders 51 for supporting and guiding the placement of the shells 1,2. The wide dinghy deck has normal rails 23.30, but also additive rails 52.53 and 54.55 to receive a propeller propulsion assembly as described in fig.19. The narrow bridge can also receive these rails. The hull is provided with a fixing rail 60 cooperating with means complementary to the bridge receiving bolts 61. In FIG. 6, there is also shown, in dashed lines, the narrow bridge of PAVL and its method of fixing shown in cross section in fig. 7. The shell 1,2 comprises a housing 65 in which is disposed an extruded rail 66 of light alloy in the shape of a U comprising two bearing faces 67 on the same plane at its upper part and two small wings
68 définissant une glissière recevant les boulons à tête carrée 69. Ce rail, coupé à longueur dans la barre extrudée, est coll vissé dans son logement au moyen de vis auto-taraudeuses 7 dans une contre-plaque 71 collée sur le fond du logement 6 avant assemblage de la coque. La partie correspondante 73 d pont vient s'appliquer sur la face supérieure 72 de la coqu séparée, après mise en place des vis correspondantes dans les tubes entr.etoises 74 engagés collés dans un profil extrudé 75 de section carrée en aliage léger autour duquel les parties supérieure 76 et inférieure 77 du pont son engagées et collées et se raccordent, à l'extérieur, sur u plan de joint 78. Une rondelle 79 et un écrou borgne 80, e acier inoxydable, assurent le blocage du boulon sur l'ensemble ainsi rigidifié.68 defining a slide receiving the square head bolts 69. This rail, cut to length in the extruded bar, is glued into its housing by means of self-tapping screws 7 in a counter plate 71 glued to the bottom of the housing 6 before assembly of the shell. The corresponding portion 73 of the bridge comes to be applied to the upper face 72 of the separate shell, after fitting the corresponding screws in the spacer tubes 74 engaged glued in an extruded profile 75 of square section made of light alloy around which the upper 76 and lower 77 parts of the bridge are engaged and glued and are connected, on the outside, to a joint plane 78. A washer 79 and a cap nut 80, e of stainless steel, secure the bolt on the assembly thus stiffened.
Sur la fig.8 on a montré en vue de dessus un exempl de barre 85 de commande au pied, par le vélip-lanch'iste, des safrans 86,87; la barre peut être également manoeuvrée manuellement en ajoutant une portion articulée verticalement. Elle pivote sur un axe vertical 88 (fig.9,10) solidaire d'une plaque 89 fixée sur le rail 30 par des boulons 90,91, une lame de ressort 92, articulée en 93 et munie d'un trou 94, fait fonction d'arrêtoir à la barre 85. Les flèches 95,96 montrent le sens de manoeuvre au pied. Les safrans 86,87 sont disposés articulés dans les paliers 35, ils comportent chacun en regard, une patte 97,98 vissée percée d'un trou 99 (fig.12) dans lequel est engagé l'extrémité 100, pliée à l'équerre, d'une tringle de renvoi 101 arrêtée par un clip constitué par une lame de ressort 102 dont l'extrémité est engagée dans un cran fraisé 103, ladite lame étant fixée sur l'équerre 97,98. Le milieu de la tringle de renvoi 101 (fig.11) comporte une patte soudée 104 munie d'une rainure 105 dans laquelle est engagée l'extrémité 106, pliée à l'équerre, d'une tige 107 soudée sur l'extrémité de la barre 85 fermée par un bouchon 109 en matière plastique. Le rappel élastique de la barre 85, dans l'axe longitudinal XX' d flotteur, est assuré au moyen de deux cordons 110,111 en matériau élastiquement défor able, attaché d'une part au crochets 112,113 des coques 1,2 et d'autre part à un anneau 114 soudé sur la barre 85, lesdits cordons ayant pour fonction, en l'absence d'actio sur la barre, de la maintenir normalement dans l'axe XX' .In fig.8 there is shown a top view of an exemplary bar 85 foot control, by the velip-lanch ' iste, rudders 86.87; the bar can also be maneuvered manually by adding a vertically articulated portion. It pivots on a vertical axis 88 (fig. 9,10) secured to a plate 89 fixed to the rail 30 by bolts 90,91, a spring leaf 92, articulated at 93 and provided with a hole 94, made bar stop function 85. The arrows 95, 96 show the direction of operation with the foot. The rudders 86.87 are arranged articulated in the bearings 35, they each have opposite, a screwed leg 97.98 pierced with a hole 99 (fig.12) in which is engaged the end 100, bent at right angles , of a deflection rod 101 stopped by a clip constituted by a spring leaf 102 the end of which is engaged in a countersunk notch 103, said blade being fixed to the bracket 97.98. The middle of the deflection rod 101 (fig. 11) comprises a welded lug 104 provided with a groove 105 in which the end 106 is engaged, bent at right angles, with a rod 107 welded on the end of the bar 85 closed by a plastic plug 109. The elastic return of the bar 85, in the longitudinal axis XX 'd float, is ensured by means of two cords 110,111 made of elastically deformable material, attached on the one hand to the hooks 112,113 of the shells 1,2 and on the other hand to a ring 114 welded to the bar 85, said cords having the function, in the absence of actio on the bar, to maintain it normally in the axis XX '.
Les fig.13, 14 montrent un exemple de variante d réalisation de flotteur selon l'invention vu de dessus et v en élévation. Il comporte des coques 115,116 solidarisées pa un pont 117 formant un ensemble monobloc. La position du mâ 118 est avancée vers l'avant et le pont se prolonge ver l'arrière' de façon à permettre toutes les manoeuvres de l'arrière, les virements de bord s 'effectuant en passant sous la voile et non plus en contournant le mât par l'avant comme sur les PAVL traditionnelles. On a disposé des cale-pieds 119,120 de chaque côté du pont et à l'arrière de celui-ci. Les flotteurs 115,116 sont symétriques par rapport à un axe YY' et disposés symétriquement par rapport à l'axe longitudinal XX' du flotteur. Une dérive centrale 121 est fixée sous chacune des coques sur des rails 122,123 solidaires du dessous des coques. Deux autres rails 124,125 disposés à l'arrière, également sur l'axe YY' , reçoivent chacun un aileron 126. Les coques sont étroites et comportent chacune, sur leur côté extérieur, une bordure 127,128 disposée au-dessus de la ligne de flottaison 129 (fig.15) , constituant une réserve de flottaison. Le dessus 130 des coques 115,116 s'élève progressivement depuis l'arrière, leur point le plus bas comportant un redan 131 de réduction de trainée, jusqu'à leur extrémité avant qui est située au- dessus de la ligne de flottaison 131. Le dessous 132,133 des bordures 127,128 s'élève en ligne droite à l'arrière 135 situé au-dessus de la ligne de flottaison 132, vers l'avant 136 nettement au-dessus de cette ligne. Le dessous 137 du pont 117 est parallèle à la ligne de flottaison jusqu'à la ligne verticale 138 où il s'élève légèrement vers l'avant.Figs. 13, 14 show an example of a variant embodiment of a float according to the invention seen from above and v in elevation. It includes shells 115,116 secured by a bridge 117 forming a one-piece assembly. The position of the mast 118 is advanced forward and the deck extends towards the rear ' so as to allow all maneuvers from the rear, the tacking being carried out by passing under the sail and no longer bypassing the mast from the front as on traditional PAVLs. 119,120 toe clips were placed on each side of and behind the bridge. The floats 115, 116 are symmetrical with respect to an axis YY 'and arranged symmetrically with respect to the longitudinal axis XX' of the float. A central fin 121 is fixed under each of the hulls on rails 122, 123 secured to the underside of the hulls. Two other rails 124, 125 placed at the rear, also on the axis YY ', each receive a fin 126. The hulls are narrow and each have, on their outside side, a border 127, 128 arranged above the water line 129 (fig.15), constituting a flotation reserve. The top 130 of the hulls 115, 116 gradually rises from the rear, their lowest point comprising a step 131 for reducing drag, to their front end which is located above the water line 131. The bottom 132,133 of the edges 127,128 rises in a straight line at the rear 135 situated above the water line 132, towards the front 136 clearly above this line. The underside 137 of the deck 117 is parallel to the water line up to the vertical line 138 where it rises slightly forward.
La coupe transversale 15 montre la section des coques 115,116; le dessous 139 de celles-ci est de forme légèrement creuse à grand rayon; leur flanc interne 140 et externe 141 sont en légère dépouille vers le bas. On voit que les bordures 127,128 correspondent à une réserve de flottabilité accroissant la surface portante du flotteur lorsqu'elle entre en contact avec l'eau. Les flancs latéraux 142,143 sont sensiblement verticaux. Le dessus 144,145 des coques est légèrement bombé sur l'arrière et sur l'avant pour faciliter l'écoulement. Le dessus 146 du pont 117 est bombé transversalement à très grand rayon et se raccorde sur les flancs par deux petits rayons 147. Le dessous 148 du pont est limité par un rayon parallèle au rayon 146. Symétriquement à l'axe XX1 on a inséré, sur l'avant du pont, une plaque de renforcement en bois 149 dans laquelle est ménagée une rainure recevant le rail 150 de fixation de 1' emplanture de mât. Le milieu de ce rail se situe au voisinage des 2/3 avant de la longueur du flotteur. Tout le volume du pont est rempli de mousse d'une densité de l'ordre de 50kg/m3. La liaison du pont sur les coques, en version polyester, est réalisée au moyen d'un plan de joint sensiblement vertical prolongeant la peau extérieure 151 et intérieure 152 parallèlement à celle de la partie supérieure des flancs 140 et 142,143 des coques, cette partie des flancs est en retrait vers l'intérieur de façon à ne pas présenter de saillie sur laquelle l'utilisateur pourrait se blesser. Les lignes de liaison pont/coques sont de plus recouvertes d'une robuste bande adhésive 154 masquant le plan de joint. Il en est de même pour les liaisons dessus/dessous de la partie supérieure et de la partie inférieure des coques réalisées avec le même plan de joint. La peau interne 148 présente des rayons 155 de raccordement vers le flanc interne des coques- L'extrémité arrière 156 (fig.14) des coques présente une courbe en surplomb sur 1 ' eau=, se terminant, en partie basse, par un redan 131 pour réduire la trainée arrière. Sur la paroi inférieure creuse des coques, on a montré en traits pointillés l'emplacement des rails 122,123 de fixation des dérives. C'est le choix de ces formes opérationnelles de dessous de coques 139, des bordures 127,128 et de leur situation par rapport à la ligne de flottaison ainsi que la disposition du pont et de la forme arrière des coques qui confère à la PAVL selon l'invention ses performances remarquables sur l'eau, en mer, sur - lac ou rivière. Bien entendu cette PAVL est réalisable en tout matéria compatible et par tout procédé de fabrication préférablement automatisable, y compris le moulage par injection. Comme sur la version des figures 1,2, on utilise avec ce flotteur tous les grééments traditionnels de PAVL.Cross section 15 shows the section of the shells 115,116; the underside 139 of these is of slightly hollow shape with a large radius; their internal side 140 and external side 141 are slightly stripped down. We see that the edges 127,128 correspond to a buoyancy reserve increasing the bearing surface of the float when it comes into contact with water. The lateral flanks 142, 143 are substantially vertical. The top 144,145 of the hulls is slightly rounded on the rear and on the front to facilitate flow. The top 146 of the bridge 117 is curved transversely to a very large radius and is connected to the sides by two small spokes 147. The bottom 148 of the bridge is limited by a radius parallel to the radius 146. Symmetrically to the axis XX 1 we have inserted , on the front of the bridge, a wooden reinforcing plate 149 in which is formed a groove receiving the rail 150 for fixing the mast base. The middle of this rail is located near 2/3 before the length of the float. The entire volume of the deck is filled with foam with a density of around 50kg / m3. The connection of the deck to the hulls, in polyester version, is carried out by means of a substantially vertical joint plane extending the outer 151 and inner 152 skin parallel to that of the upper part of the sides 140 and 142,143 of the hulls, this part of the sides is recessed inward so as not to have a projection on which the user could be injured. The bridge / hull connection lines are also covered with a robust adhesive strip 154 masking the joint plane. It is the same for the links above / below the upper part and the lower part of the shells produced with the same joint plane. The internal skin 148 has spokes 155 for connection to the internal flank of the hulls. The rear end 156 (fig. 14) of the hulls has an overhanging curve on the water =, ending, in the lower part, with a step. 131 to reduce the rear drag. On the hollow bottom wall of the shells, we have shown in dotted lines the location of the rails 122, 123 for fixing the fins. It is the choice of these operational forms of undershells 139, the edges 127,128 and their location relative to the waterline as well as the arrangement of the deck and the rear shape of the hulls that gives the PAVL according to the invention its remarkable performance on water, at sea, on - lake or river. Of course, this PAVL can be produced in any compatible material and by any preferably automatable manufacturing process, including injection molding. As in the version of Figures 1,2, we use with this float all the traditional rigging of PAVL.
Les fig.16, 17 et 18 montrent un exemple selon l'invention, d'un chariot de transport du flotteur au plan d'eau. Ledit chariot est constitué d'une structure tubulaire 160 comportant un premier tube 161 plié en U et un second tube soudé parallèlement au tube 161 à une distance entre axes correspondant au pas entre les paliers 35 de safrans des coques du flotteur. Des axes porteurs 163,164 sont soudés au droit de l'axe vertical YY' des trous de paliers 35 pour permettre de les engager dans les trous desdits paliers lors de l'utilisation du chariot. Le tube 162 reçoit au voisinage des ailes 165,166 (fig.18) un tube parallèle 167,168; les extrémités 169 des ailes 165,166 et des tubes 167,168 sont applaties et percées d'un trou recevant un axe 170 sur lequel tourne librement une roue 171,172. Ce chariot, peu encombrant, est très facilement et très rapidement mis en place sur la PAVL et retiré pour assurer aisément le transport du flotteur.Fig.16, 17 and 18 show an example according to the invention, a carriage for transporting the float to the water. Said carriage consists of a tubular structure 160 comprising a first tube 161 bent in a U and a second tube welded parallel to the tube 161 at a distance between axes corresponding to the pitch between the bearings 35 of rudders of the hulls of the float. Supporting pins 163, 164 are welded to the right of the vertical axis YY 'of the bearing holes 35 to allow them to be engaged in the holes of said bearings when the carriage is in use. The tube 162 receives in the vicinity of the wings 165,166 (FIG. 18) a parallel tube 167,168; the ends 169 of the wings 165,166 and of the tubes 167,168 are flattened and pierced with a hole receiving an axis 170 on which a wheel 171,172 rotates freely. This space-saving trolley is very easily and quickly set up on the PAVL and removed to easily transport the float.
Sur la fig.19 on a représenté, vu en élévation le flotteur des fig.1,2 dont l'arrière du pont 3 comporte un berceau 180 monté en chape sur le pont. Il est fixé sur les rails 30 ou 54,55 (fig.6) . Ce berceau reçoit un ensemble de motorisation 181 entraînant une hélice 182. Une barre 183 permet de diriger le flotteur en absence de safran et d'aileron arrière. Cette motorisation permet de le transformer en pseudo "scooter des mers".On fig.19 there is shown, seen in elevation the float of fig.1,2 whose rear of the bridge 3 includes a cradle 180 mounted in clevis on the bridge. It is fixed on the rails 30 or 54,55 (fig. 6). This cradle receives a motorization assembly 181 driving a propeller 182. A bar 183 makes it possible to direct the float in the absence of rudder and rear wing. This engine makes it possible to transform it into a pseudo "sea scooter".
Dans l'utilisation en dériveur on peut employer un gréément fixe à wishbone équipé d'un mouflage de rappel et un foc accroché sur un câble placé entre les anneaux de remorquage 22 (fig.2) ou tout autre gréément classique adaptable. On peut également entraîner les safrans par un système de câbles et poulies au lieu d'une tringlerie. In use as a dinghy, one can use a fixed wishbone rigging equipped with a hauling system and a jib hooked on a cable placed between the towing rings 22 (fig.2) or any other conventional adaptable rigging. The rudders can also be driven by a system of cables and pulleys instead of a linkage.
