Abstract
Description
COQUE DE BATEAU A SUSTENTATION TRIANGULAIRE
La présente invention a pour objet un dispositif de coque de bateau à sustentation triangulaire.BOAT HULL WITH TRIANGULAR SUPPORT
The present invention relates to a boat hull device with triangular lift.
I1 est destiné à permettre la réalisation de navires de plaisance à voiles ou à moteur joignant les avantages des bateaux à coque unique à ceux des bateaux à coques multiples. I1 is intended to allow the realization of pleasure craft with sails or motor joining the advantages of single hull boats to those of multiple hull boats.
Les dispositifs de ce genre réalisés à ce jour peuvent se ranger dans deux grandes catégories, d'une part les monocoques, peu encombrants, mais à la stabilité limitée et obligatoirement pourvus d'une quille lestée ou de grande taille, augmentant la surface mouillée et par conséquent la résistance à l'avancement, d'autre part, les multicoques, catamarans ou trimarans, plus stables, mais très encombrants et d'un maniement délicat.Devices of this kind made to date can fall into two main categories, on the one hand, monohulls, which are compact, but have limited stability and are necessarily fitted with a weighted or large keel, increasing the wetted surface and consequently resistance to advancement, on the other hand, multihulls, catamarans or trimarans, more stable, but very bulky and of delicate handling.
Le dispositif suivant la présente invention supprime tous ces inconvénients. En effet, il permet d'obtenir à la fois une excellente pénétration dans l'eau due à une faible résistance à l'avancement et une grande stabilité, aussi bien au roulis qu'au tangage; grâce à trois points d'appui judicieusement répartis sur l'eau, tout en présentant un encombrement et une facilité de maniement proche de ceux des monocoques, par suite de sa conception monobloc.The device according to the present invention eliminates all these drawbacks. Indeed, it makes it possible to obtain both excellent penetration in water due to low resistance to advancement and great stability, both in roll and in pitching; thanks to three support points judiciously distributed on the water, while presenting a bulk and an ease of handling close to those of monohulls, due to its monobloc design.
Il est constitué par la combinaison d'un ensemble monobloc formant en partie basse trois petites coques disposées en triangle, l'une centrale, à l'avant, les deux autres latérales et à l'arrière, s'appuyant sur l'eau au maTtre bau, dégageant à l'avant deux canaux hors d'eau se rejoignant en un seul derrière la coque centrale, le fond étant pourvu à l'arrière d'un étambot destiné à recevoir le safran et le fond de chacune des deux coques latérales pouvant recevoir un lest dont le poids est déterminé en fonction dc l'équipement et de l'usage du bateau. It consists of the combination of a monobloc assembly forming in the lower part three small shells arranged in a triangle, one central, at the front, the other two lateral and at the rear, leaning on the water at mast bau, releasing at the front two channels out of water joining in one behind the central hull, the bottom being provided at the rear with a stern intended to receive the rudder and the bottom of each of the two side hulls can receive a ballast whose weight is determined according to the equipment and the use of the boat.
Sur les dessins annexés, donnés à titre d 'exemple non limitatif d'une des formes de l'invention:
La figure 1 représente une vue en élévation de l'invention montrant par une partie hachurée l'emplacement éventuel du lest,
La figure 2 est une demi-coupe vue de dessous, suivant la ligne de flottaison,
Les figures 3 et 4 montrent à une autre échelle, le dispositif respectivement de l'avant et de 1' arrière,
La figure 5 est une coupe transversale suivant les flèches
A-A de la figure 1, montrant le montage d'une quille éventuelle
Le dispositif, figure 1 à 4 est constitué d'un ensemble monobloc 1 pouvant être réalisé en moulage unique en résine synthétique renforcée de fibres de verre, ou toute autre matière, formant à sa partie basse trois petites coques disposées en triangle, l'une à l'avant 2, les deux autres 3, 4 latéralement à 1' arrière. In the accompanying drawings, given by way of nonlimiting example of one of the forms of the invention:
FIG. 1 represents a view in elevation of the invention showing by a hatched part the possible location of the ballast,
FIG. 2 is a half-section seen from below, along the water line,
FIGS. 3 and 4 show on another scale, the device respectively from the front and from the rear,
Figure 5 is a cross section along the arrows
AA of figure 1, showing the mounting of a possible keel
The device, Figure 1 to 4 consists of a one-piece assembly 1 which can be produced by single molding in synthetic resin reinforced with glass fibers, or any other material, forming at its lower part three small shells arranged in a triangle, one at the front 2, the other two 3, 4 laterally at the rear.
Les coques latérales forment avec la coque centrale, au dessus de la ligne de flottaison 10, deux canaux hors d'eau 5, 5' qui n'en font plus qu'un à l'arrière 6. L'écoulement de l'eau entre les coques (flèches figure 2) crée un effet de venturi permettant d ' atteindre une vitesse importante avec une puissance réduite.The lateral hulls form, with the central hull, above the waterline 10, two out of water channels 5, 5 'which become one at the rear 6. The flow of water between the hulls (arrows in figure 2) creates a venturi effect making it possible to reach a high speed with reduced power.
Les coques latérales 3, 4 sont dessinées pour prendre appui sur l'eau au niveau du maitre bau, de manière à assurer la plus grande stabilité au roulis. Elles peuvent comporter dans leur partie basse un lest 7 dont le poids est adapté à la destination du bateau.The lateral hulls 3, 4 are designed to rest on the water at the level of the master beam, so as to ensure the greatest roll stability. They may include in their lower part a ballast 7 whose weight is adapted to the destination of the boat.
A l'arrière, sous le fond central, un étambot 8, intégré dans l'ensemble monobloc 1, est destiné à recevoir un safran 9.At the rear, under the central bottom, a stern 8, integrated in the monobloc assembly 1, is intended to receive a rudder 9.
Suivant une variante d'exécution (figure 5), l'ensemble peut être équipé, entre les coques latérales 3, 4, d'une quille traditionnelle 11 construite en matériau synthétique sur lest métallique, située dans l'axe longitudinal, et maintenue par deux arceaux 12 en acier inoxydable. According to an alternative embodiment (Figure 5), the assembly can be equipped, between the side shells 3, 4, with a traditional keel 11 constructed of synthetic material on metal ballast, located in the longitudinal axis, and maintained by two stainless steel arches 12.
Grâce à ses excellentes performances, obtenues avec une puissance infèrieure à celle nécessaire avec les coques actuellement existantes, grâce à sa facilité de maniement, à sa grande stabilité malgré son volume réduit, grâce à sa possibilité de fabrication par moulage unique, le dispositif qui vient d'être décrit se prête particulièrement bien à la réalisation de bateaux de plaisance de toutes dimensions, aussi bien à voiles qu'à moteur.Thanks to its excellent performance, obtained with a power lower than that necessary with the hulls currently existing, thanks to its ease of handling, to its great stability despite its reduced volume, thanks to its possibility of manufacturing by unique molding, the device which comes to be described lends itself particularly well to the production of pleasure boats of all sizes, both sail and motor.
Le positionnement des divers éléments constitutifs donne à ce dispositif un maximum d'effets utiles qui n' avaient pas été obtenus à ce jour par des dispositifs similaires.The positioning of the various constituent elements gives this device a maximum of useful effects which had not been obtained to date by similar devices.
Cependant, les formes et dispositions des différents éléments ainsi que les matières utilisées pour leur fabrication pourront varier dans la limite des équivalents, sans changer pour cela la conception générale de l'invention qui vient d'être décrite. However, the shapes and arrangements of the various elements as well as the materials used for their manufacture may vary within the limit of equivalents, without thereby changing the general conception of the invention which has just been described.
