CATA.vzRAN DE PETITE TAILLE
La présente invention concerne un petit bateau de type cata- maran. Elle se distingue de celles existantes par la réalisation d'un catamaran de petite taille nécessitant des formes de coques nouvelles et un gréément original.SMALL SIZE CATA.vz
The present invention relates to a small catamaran type boat. It differs from existing ones by the creation of a small catamaran requiring new hull shapes and original rigging.
Cette invention a l'avantage, de part sa taille, d'être aussi facilement transportable qu'une planche à voile, et offre une sta bilité et une capacité de redressement nettement supérieures à celles d'un catamaran ordinaire. This invention has the advantage, due to its size, of being as easily transportable as a windsurfing board, and offers a stability and a recovery capacity clearly superior to that of an ordinary catamaran.
Ce catamaran de petite taille est constitué de deux coques ayant une forme très large et assez plate, avec un léger "V" dans sa partie avant, ce qui permet une grande surface portante pour une petite taille. This small catamaran is made up of two hulls with a very wide and fairly flat shape, with a slight "V" in its front part, which allows a large bearing surface for a small size.
Les coques sont entièrement fermées et reliées entre elles par deux poutres métalliques démontables. The hulls are fully closed and connected to each other by two removable metal beams.
le dispositif objet de l'invention, comporte, outre la forme des coques:
-Un trampoline situé entre les coques; et maintenu en tension par les poutres.the device which is the subject of the invention, comprises, in addition to the shape of the shells:
-A trampoline located between the hulls; and kept in tension by the beams.
-Un gréément "dipode", constitué d'un mat démontable sur chaque coque. -A "dipod" rig, consisting of a removable mast on each hull.
I1 est donné à titre d'exemple non limitatif, un mode de réalisation se référant aux dessins çi-annexés:
Figure I: Vue en plan
Figure 2: Vue de profil
La Figure I représente une vue en plan de l'ensemble qui comprend les deux coques (I) de forme très large et assez plate, maintenues entre elles par deux poutres (2) avant et arrière, fixées sur chaque coque par boulonnage (3). Entre les coques est disposé un trampoline (4) en toile plastifiée, maintenu en tension entre les poutres par laçage.I1 is given by way of nonlimiting example, an embodiment referring to the attached drawings:
Figure I: Plan view
Figure 2: Profile view
Figure I shows a plan view of the assembly which includes the two hulls (I) of very wide and fairly flat shape, held together by two beams (2) front and rear, fixed to each hull by bolting (3) . Between the shells is placed a trampoline (4) in plasticized canvas, kept in tension between the beams by lacing.
Sur chaque coque est fixé un mat (5) pouvant pivoter dans un puits étanche. On each hull is fixed a mat (5) which can pivot in a sealed well.
La direction du bateau est assurée par une barre d'accouplement rigide (6) rendant solidaires les deux safrans (7). The direction of the boat is ensured by a rigid coupling bar (6) making the two rudders (7) integral.
Chaque coque est en outre dotée d'une dérive pivotante se logeant dans un-puits (8). Each hull is furthermore provided with a pivoting fin housed in a well (8).
Les deux écoutes de voile sont renvoyées vers le barreur, à l'aide de deux poulies (9). The two sail sheets are returned to the coxswain, using two pulleys (9).
La Figure 2 représente une vue de profil qui permet de distinguer la forme et l'emplacement des deux plans de voilure (I) ainsi que les deux dérives pivotantes (2). Figure 2 shows a side view which distinguishes the shape and location of the two sail planes (I) and the two pivoting fins (2).
De conception simple, puisque ce catamaran de petite taille peut Btre réalisé en matériau synthétique et moulé, il présente une facilité de transport, puisque démontable. Simple in design, since this small catamaran can be made of synthetic and molded material, it is easy to transport, since it can be dismantled.
Par ailleurs, ce catamaran a é-té conçu pour assurer par ses formes originales une très grande stabilité. La largeur de ses coques offre une résistance à la submersion et leur permet au contraire de planer à la surface de l'eau, dans les mimes conditions qu'une planche à voile. In addition, this catamaran has been designed to provide great stability with its original shapes. The width of its hulls offers resistance to submersion and on the contrary allows them to hover on the surface of the water, in the same conditions as a windsurfing board.
Le choix d'un gréément "bipode" se justifie pour deux raisons:
Il permet une meilleure rdpartition de la surface de voile en nécéssitant une moindre hauteur de mat. Le centre de voilure se trouve ainsi abaissé et diminue d'autant le couple de chavirage.The choice of a "bipod" rig is justified for two reasons:
It allows a better distribution of the sail surface by requiring a lower mast height. The sail center is thus lowered and therefore reduces the capsizing torque.
En cas de chavirage, celui-çi est stoppé en position verticale par le mat étanche et une légère poussée en'type de mat suffit à redresser le catamaran. In the event of a capsize, it is stopped in a vertical position by the waterproof mast and a slight push in the mast type is enough to straighten the catamaran.
Ce type de catamaran se présente donc comme un nouvel engin ajoutant une stabilité et une sécurité accrues aux performances spécifiques de cette catégorie de bateaux à voile. This type of catamaran therefore presents itself as a new craft adding increased stability and safety to the specific performance of this category of sailing boats.
