Description

L'invention concerne la base renflée d'une quille de bateau, notamment la base d'une des quilles destinées à équiper un bateau du type catamaran.The invention relates to the swollen base of a boat keel, in particular the base of one of the keels intended to equip a catamaran type boat.

On connaít déjà une quille d'un bateau du type catamaran qui est renflée à sa base et dont la section horizontale est étroite dans sa partie haute et élargie dans sa partie basse pour former un patin, comme montré dans le brevet de modèle américain US Des. 362 835, le patin large permettant d'obtenir un effet de "foil" sous spinnaker avec des vents portants.We already know a keel of a catamaran type boat which is swollen at its base and whose horizontal section is narrow in its upper and enlarged part in its lower part to form a skid, as shown in the patent for American model US Des. 362 835, the wide pad providing an effect of "foil" under spinnaker with carrying winds.

Par ailleurs, on sait aussi que les bateaux de plaisance du type catamaran sont utilisés notamment prés des plages sur lesquelles ils sont traínés ou tractés, posés sur leurs quilles. Ces bateaux sont souvent tractés sur les plages sans moyen extérieur et, en raison de leur coque en V formant un socle de charrue, leur traction est très difficile et pénible. La présence de quilles à bases renflées en forme de patins, aux extrémités inférieures, en facilite la traction.In addition, we also know that pleasure boats of the catamaran type are used in particular near the beaches on which they are towed or towed, put on their skittles. These boats are often towed on the beaches without external means and, due to their V-shaped hull forming a plow base, their traction is very difficult and painful. The presence of bulges with bulging bases in shape of skids, at the lower ends, facilitates traction.

Un autre avantage des quilles à patin de ce type tient à ce qu'elles constituent, pour l'utilisateur, des moyens d'accrochage lorsque le bateau chavire, ce qui est dans ce cas fréquent. L'utilisateur peut caler ses talons contre le patin dune des quilles pour faire remonter le bateau.Another advantage of skates of this type is that they constitute, for the user, attachment means when the boat capsize, which in this case is frequent. User can wedge their heels against the skid of one of the skittles to bring the boat up.

Toutefois, ces patins, comme ils ne forment qu'une seule pièce avec le reste de la quille, présentent l'inconvénient d'être fragiles et de s'user rapidement, ce qui a pour effet d'entraíner une usure rapide de l'ensemble de la quille et une dégradation de la structure générale des coques ou de l'une des coques du catamaran.However, these pads, as they form a single piece with the rest of the keel, have the disadvantage of being fragile and wearing out quickly, which has the effect of causing rapid wear of the entire keel and degradation of the general structure of the hulls or of one of the hulls of the catamaran.

De plus, la fabrication de cette quille qui se termine en forme de patin nécessite l'installation, sous la quille, d'un moule de forme compliquée - il faut prévoir un moule avec dépouille et qui est constitué de plusieurs parties - est délicate et d'un coût élevé.In addition, the manufacture of this keel which ends in the shape of a skate requires the installation, under the keel, of a mold of complicated shape - it is necessary provide a mold with draft and which consists of several parts - is delicate and high cost.

Un objet de la présente invention est de remédier à ces inconvénients: à savoir usure rapide, dégradation de la coque, fabrication coûteuse et malcommode, en prévoyant toujours une quille à base renflée qui offre un effet de « foil », d'une part, et qui facilite le déplacement du catamaran sur une plage.An object of the present invention is to remedy these drawbacks: know rapid wear, hull degradation, expensive manufacturing and inconvenient, always providing a bulge with a swollen base which offers an effect on the one hand, and which facilitates the movement of the catamaran on a beach.

Suivant une caractéristique de l'invention, il est prévu un patin séparé mais qui peut être monté et fixé solidement sous la quille d'une coque de bateau par des moyens simples.According to a characteristic of the invention, there is provided a separate pad but which can be mounted and fixed securely under the keel of a boat hull by simple means.

Suivant une autre caractéristique, il est prévu un patin séparé dont le montage et le démontage sous la quille sont faciles au moyen de vis verticales traversant le patin et se vissant dans des trous forés dans la base de la quille.According to another characteristic, a separate pad is provided, the assembly and disassembly under the keel is easy by means of vertical screws crossing the skate and screwing into holes drilled in the base of the keel.

Il devient ainsi possible, après avoir apprécié l'état d'usure du patin, de le démonter et de le remplacer avant que la dégradation de la quille devienne irréversible.It thus becomes possible, after having assessed the state of wear of the pad, to disassemble and replace it before degradation of the keel becomes irreversible.

Suivant une autre caractéristique de l'invention, il est prévu un patin dont la surface a été enduite d'une matière réfléchissante pour repérer plus facilement le bateau lors du chavirement du bateau.According to another characteristic of the invention, a pad is provided, the surface has been coated with a reflective material for easier identification the boat when the boat capsized.

Selon une autre caractéristique de l'invention, il est prévu un patin séparé plus large que la base inférieure de la quille et dont la face supérieure comporte une partie centrale qui épouse la forme de ladite base inférieure et qui est bordée, de chaque côté de ladite base, par des rebords longitudinaux.According to another characteristic of the invention, a separate pad is provided wider than the lower base of the keel and the upper side of which is a central part which follows the shape of said lower base and which is bordered, on each side of said base, by longitudinal edges.

Selon une autre caractéristique de l'invention, le patin séparé présente une série de trous alignés dans le sens longitudinal au centre de ladite partie centrale en face de trous forés dans ladite base, à travers lesquels passent des vis.According to another characteristic of the invention, the separate pad has a series of holes aligned in the longitudinal direction at the center of said central part opposite holes drilled in said base, through which screws pass.

Selon une autre caractéristique de l'invention, le patin séparé, vu de profil, a une épaisseur variable de manière à présenter une surface inférieure rectiligne, quelle que soit le profil de ladite base inférieure de la quille. According to another characteristic of the invention, the separate pad, seen in profile, has a variable thickness so as to present a rectilinear lower surface, whatever the profile of said lower base of the keel.

Les caractéristiques de l'invention mentionnées ci-dessus, ainsi que d'autres, apparaítront plus clairement à la lecture de 1 a description suivante d'un exemple de réalisation, ladite description étant faite en relation avec les dessins joints:

  • la Fig. 1 est une vue schématique d'une coupe transversale d'une coque de bateau et notamment d'une quille sous laquelle est monté un patin suivant l'exemple de réalisation,
  • la Fig. 2 est une vue schématique d'une coupe partielle longitudinale de la quille de la Fig. 1, sous laquelle est accroché un patin suivant l'invention, et
  • la Fig. 3 est une vue schématique éclatée en élévation d'une coque à laquelle on accroche un patin suivant l'invention.
    • The characteristics of the invention mentioned above, as well as others, will appear more clearly on reading the following description of an exemplary embodiment, said description being made in relation to the accompanying drawings:
  • Fig. 1 is a schematic view of a cross section of a boat hull and in particular of a keel under which a skate is mounted according to the embodiment example,
  • Fig. 2 is a schematic view of a partial longitudinal section of the keel of FIG. 1, under which a shoe according to the invention is hung, and
  • Fig. 3 is a schematic exploded view in elevation of a shell to which a shoe according to the invention is attached.

    • La Fig. 1 montre la coupe transversale d'une coque 1 se terminant vers le bas par une quille 2, de plus en plus fine, sous laquelle est monté un patin 3. Le patin 3 a une largeur sensiblement plus grande que la quille 2, à sa base inférieure 4, et comme le montre la Fig. 1, présente de chaque côté de la base 4 de la quille 2 des rebords 5 qui créent entre eux une partie centrale 6.Fig. 1 shows the cross section of a shell 1 ending towards the bottom by a keel 2, thinner and thinner, under which is mounted a shoe 3. The shoe 3 has a width substantially greater than the keel 2, at its lower base 4, and as shown in FIG. 1, present on each side of the base 4 of the keel 2 of the flanges 5 which create between them a central part 6.

    Le long de la ligne centrale longitudinale de la partie 6, comme le montrent les Figs. 2 et 3, sont percés verticalement, de place en place, des trous 7 qui se trouvent en face de trous 8 forés verticalement dans la quille 2 et à travers lesquels sont enfoncées des vis 9.Along the longitudinal center line of Part 6, as shown Figs. 2 and 3, are drilled vertically, from place to place, holes 7 which are found opposite holes 8 drilled vertically in the keel 2 and through which are driven screws 9.

    La Fig. 2 montre partiellement que le patin 3 est placé en butée contre le bord arrière 19 de la base 4 de la quille 2, ce qui assure au moment de la mise en place du patin 3 un alignement correct des trous 7 et 8. Les trous 8 peuvent être, à l'avance, munis de viroles filetées, ce qui assure une meilleure sécurité.Fig. 2 partially shows that the shoe 3 is placed in abutment against the rear edge 19 of the base 4 of the keel 2, which ensures at the time of setting place of skate 3 a correct alignment of the holes 7 and 8. The holes 8 can be, in advance, fitted with threaded ferrules, which ensures better security.

    La vue éclatée de profil de la Fig. 3 montre que le patin 3 peut avoir une épaisseur variable, ce qui lui permet de présenter une face inférieure rectiligne.The exploded side view of FIG. 3 shows that skate 3 can have a variable thickness, which allows it to have a rectilinear underside.

    On comprendra encore que d'autres moyens de fixation peuvent être adaptés pour fixer ce patin de manière optimum.It will also be understood that other fixing means can be adapted to fix this pad optimally.
