Description

BATEAU MULTICOQUES A DOUBLE PONT DESCRIPTIONBOAT MULTICOQUES DOUBLE BRIDGE DESCRIPTION

DOMAINE DE L'INVENTION L'invention concerne le domaine des bateaux multicoques, notamment des catamarans ou des trimarans, du genre comprenant au moins deux coques, une structure de liaison des coques entre elles et un pont étanche.  FIELD OF THE INVENTION The invention relates to the field of multihull boats, in particular catamarans or trimarans, of the type comprising at least two hulls, a hull connecting structure between them and a watertight deck.

ARRIERE PLAN TECHNOLOGIQUEBACKGROUND TECHNOLOGY

Dans les bateaux connus du genre en question, les ponts sont étanches et sont toujours positionnés au dessus de la structure de liaison des coques entre elles. Le volume comptabilisé pour le calcul de la jauge correspond, pour les bateaux de longueur inférieure à 15 mètres, au volume étanche situé au dessous du pont étanche, alors que, pour les bateaux de longueur supérieure, on comptabilise également les superstructures.  In known boats of the kind in question, the bridges are waterproof and are always positioned above the hull connection structure between them. The volume recorded for the calculation of the gauge corresponds, for the boats of length less than 15 meters, to the tight volume located below the waterproof deck, whereas, for the boats of greater length, one counts also the superstructures.

Dans le cas des bateaux multicoques de longueur inférieure à 15 mètres, le volume étanche de la structure de liaison représente une part non négligeable (de 10 à 90 %) du volume total comptabilisé pour le calcul du tonnage.  In the case of multihull vessels of less than 15 meters in length, the tight volume of the connecting structure represents a significant proportion (from 10% to 90%) of the total volume recorded for the tonnage calculation.

Or il se trouve que, dans la pratique, le souhait de tout armateur et bien évidemment de tout navigateur, est d'obtenir, pour un tonnage donné, un bateau de dimensions (longueur et largeur) les plus grandes possibles.  Now it turns out that, in practice, the wish of any shipowner and obviously of any navigator, is to obtain, for a given tonnage, a boat of dimensions (length and width) the greatest possible.

C'est donc dans la diminution des volumes comptabilisés que des recherches ont été entreprises par le demandeur.  It is therefore in the reduction of the volumes recorded that research was undertaken by the applicant.

RESUME DE L'INVENTION L'invention vise à réaliser un dispositif du genre en question destiné à mettre en oeuvre une solution inédite et originale apte à diminuer le volume des éléments comptabilisés pour calculer le tonnage et à remplacer cette diminution de volume par un accroissement des dimensions des volumes étanches situés sous le pont étanche donc celles (longueur et largeur) du bateau.  SUMMARY OF THE INVENTION The purpose of the invention is to provide a device of the kind in question designed to implement a novel and original solution capable of reducing the volume of the elements counted to calculate the tonnage and to replace this volume reduction by an increase in the dimensions of the watertight volumes located under the waterproof deck so those (length and width) of the boat.

Elle concerne à cet effet, un bateau multicoques qui se caractérise essentiellement en ce qu'il comporte un double pont constitué : a) d'un pont étanche positionné sous la structure de liaison, au niveau de la partie supérieure des coques; b) d'un pont non étanche positionné sur la structure de liaison; et en ce que les parties latérales de la structure de liaison, qui sont comprises entre lesdits deux ponts, sont ouvertes aux intempéries et servent de sabords de décharge.  It concerns for this purpose, a multihull boat which is characterized in that it comprises a double bridge consisting of: a) a waterproof bridge positioned under the connecting structure, at the upper part of the hulls; b) an unsealed bridge positioned on the connecting structure; and in that the lateral parts of the connecting structure, which are between said two bridges, are open to the weather and serve as discharge ports.

Ainsi réalisée, la structure de liaison qui est rendue non étanche, n'est plus comptabilisée.  Thus achieved, the link structure which is made leakproof, is no longer counted.

La conception selon l'invention pourrait s'appliquer à des bateaux monocoques mais le gain en volume comptabilisé pour le calcul du tonnage serait très inférieur. 5 PRESENTATION DES FIGURES Les caractéristiques et les avantages de l'invention vont apparaître plus clairement à la lecture de la description détaillée qui suit d'au moins un mode de réalisation préféré de celle-ci donné à titre d'exemple non limitatif et représenté aux dessins annexés. Sur ces dessins: - la figure 1 représente, en coupe transversale, la partie d'un bateau multicoques connu comprenant deux coques, une structure de liaison étanche et un pont étanche; - la figure 2 représente, en coupe transversale, la partie d'un bateau multicoques selon l'invention comprenant deux coques, une structure de liaison non étanche, un pont supérieur non étanche et un pont inférieur étanche; - la figure 3 représente, en vue de dessus, le bateau tel que représenté à la figure 2, pont non étanche enlevé.  The design according to the invention could be applied to monohull boats but the gain in volume recorded for the calculation of the tonnage would be much lower. PRESENTATION OF THE FIGURES The characteristics and advantages of the invention will appear more clearly on reading the following detailed description of at least one preferred embodiment thereof given by way of nonlimiting example and represented in the drawings. attached drawings. In these drawings: - Figure 1 shows, in cross section, the part of a known multihull boat comprising two shells, a sealed connection structure and a sealed bridge; - Figure 2 shows, in cross section, the part of a multihull boat according to the invention comprising two shells, a non-sealed connection structure, a top unsealed bridge and a sealed lower bridge; - Figure 3 shows, in top view, the boat as shown in Figure 2, non-sealed bridge removed.

DESCRIPTION DETAILLEE DE L'INVENTION  DETAILED DESCRIPTION OF THE INVENTION

Le bateau multicoques, représenté à la figure 1, comprend au moins deux coques (1), une structure (étanche) de liaison (2) des coques entre elles et un pont étanche (3).  The multihull boat, shown in Figure 1, comprises at least two shells (1), a structure (sealed) connecting (2) shells together and a sealed bridge (3).

Le volume de la structure de liaison (2), qui est étanche, est dans ce cas comptabilisé. Le volume comptabilisé est donc égal à 2 x V1 + V2 dans lequel VI correspond au volume de chaque coque et V2 celui de la structure de liaison.  The volume of the connecting structure (2), which is sealed, is in this case counted. The volume counted is therefore equal to 2 x V1 + V2 in which VI corresponds to the volume of each shell and V2 that of the link structure.

Les sabords de décharge (5) se situent entre le pont étanche (3) et les pavois de bordage (6).  The freeing ports (5) are located between the watertight deck (3) and the curtain bulwarks (6).

Le bateau multicoques, représenté à la figure 2, comprend au moins deux coques (1), une structure de liaison (2) des coques entre elles et un double pont (3,4). Le double pont est constitué : a) d'un pont étanche (3) positionné sous la structure de liaison (2), au niveau de la partie supérieure (1A) des coques (1) ; b) d'un pont non étanche (4) positionné sur la structure de liaison (2).  The multihull boat, shown in Figure 2, comprises at least two shells (1), a connecting structure (2) hulls between them and a double bridge (3,4). The double bridge consists of: a) a waterproof bridge (3) positioned under the connecting structure (2), at the upper part (1A) of the shells (1); b) an unsealed bridge (4) positioned on the connecting structure (2).

La structure de liaison (2), qui est non étanche, comporte des parties latérales (2A), comprises entre lesdits deux ponts, ouvertes aux intempéries et servant de sabords de décharge.  The connecting structure (2), which is not waterproof, has side portions (2A) between said two bridges, open to the weather and serving as freeing ports.

Le volume comptabilisé est donc égal à 2 x VI.  The volume counted is therefore equal to 2 x VI.

Le pont non étanche (4) est constituée d'éléments à claire-voie des types caillebotis ou treillis.  The non-waterproof bridge (4) consists of slatted elements of the slatted or lattice types.

La structure de liaison (2) est constituée d'au moins deux poutres maîtresses transversales (2B) et (2C) placées à la proue et à la poupe du bateau.  The connecting structure (2) consists of at least two transverse girders (2B) and (2C) placed at the bow and stern of the boat.

Les poutres maîtresses transversales (2B) et (2C) soutiennent des poutrelles (2D).  The transverse girders (2B) and (2C) support girders (2D).

Les poutrelles (2D), associées à des traverses (2E), soutiennent le pont non étanche (4).  The beams (2D), associated with sleepers (2E), support the unsealed bridge (4).

Le pont étanche (3) est pris en sandwich entre les poutrelles (2D) et la partie supérieure (1A) des coques (1).  The waterproof bridge (3) is sandwiched between the beams (2D) and the upper part (1A) of the shells (1).

Toutes les parties constitutives du bateau selon l'invention sont réalisées au moyen de matériaux couramment utilisés en construction navale (métal, polyester, carbone, etc.).  All the constituent parts of the boat according to the invention are made using materials commonly used in shipbuilding (metal, polyester, carbon, etc.).

Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits et représentés pour lesquels on pourra prévoir d'autres variantes, en particulier dans la nature, le type et les dimensions des coques, des structures de liaison et des ponts et l'étendre à d'autres types de bateaux, sans pour cela sortir du cadre de l'invention.  Of course, the invention is not limited to the embodiments described and shown for which other variants may be provided, in particular in the nature, type and dimensions of the hulls, connecting structures and bridges and extend to other types of boats, without departing from the scope of the invention.
