Abstract

The invention concerns a device for folding the floats of a trimaran widthways on its central hull, for quickly reducing the span of a trimaran, except when it is using sails, to the span of a monohull of similar length, without decreasing its habitability. The device consists of arm links, made up of tubes of different lengths and mutually articulated at their ends. After putting down the locking rod joint (G) of axes (F and C), the user only has to lift float (H) which will describe by itself a curve (I) and will inevitably settle on the edge of the central hull, without increasing its length. The device is particularly designed for making a trimaran, except when making use of sails, as compact as a monohull while retaining the same habitability.

Description

DESCRIPTION
La présente invention, concerne un dispositif qui place, en dehors de la navigation sous voiles, les flotteurs d'un trimaran sur et dans le largeur de sa coque centrale.DESCRIPTION
The present invention relates to a device which places, apart from sailing under sails, the floats of a trimaran over and across the width of its central hull.

Le pliage des bras de liaison des trimarans se fait traditionnellement pour que les deux flotteurs viennent s'encastrer latéralement dans les cavités aménagées de chaque côté, sous la coque centrale, sans s'en désolidariser, ce qui est rapide, mais réduit considérablement le volume habitable intérieur de cette dernière. The folding of the link arms of the trimarans is traditionally done so that the two floats are laterally embedded in the cavities provided on each side, under the central hull, without detaching from it, which is rapid, but considerably reduces the volume habitable inside the latter.

Les trimarans qui conservent le volume intérieur habitable maximum de la coque centrale, rangent les flotteurs sur cette dernière, après un long démontage et en s'aidant d'appareils de manutention extérieurs et additionnels. The trimarans which keep the maximum habitable interior volume of the central hull, store the floats on the latter, after a long disassembly and with the help of external and additional handling equipment.

Le dispositif selon l'invention permet de remédier à l'un ou l'autre inconvénient. The device according to the invention overcomes one or the other drawback.

Chaque bras de liaison pliable comporte, en effet, selon une première caractéristique, un assemblage de tubes fixés entre eux, à leurs extrémités par un axe.Each foldable connecting arm comprises, according to a first characteristic, an assembly of tubes fixed to each other, at their ends by an axis.

La disposition de ces tubes permet par pliage de déplacer horizontalement le flotteur à une distance proportionnelle de la coque principale ou de le positionner au dessus de cette dernière sans jamais s'en désolidariser. The arrangement of these tubes allows by folding to horizontally move the float at a proportional distance from the main hull or to position it above the latter without ever detaching from it.

Selon l'importance du bateau, la manoeuvre de levage peut être assistée par le matériel propre à celui-ci. La proportion entre les longueurs des différents tubes qui constituent un bras de liaison et leurs points de fixation, permet d'obtenir le maximum de distance entre la position plié et déplié, en passant par un nombre infini de positions intermédiaires. Depending on the size of the boat, the lifting operation can be assisted by its own equipment. The proportion between the lengths of the different tubes which constitute a link arm and their fixing points, makes it possible to obtain the maximum distance between the folded and unfolded position, passing through an infinite number of intermediate positions.

La figure 1 représente en plan le bord d'une coque principale et deux bras de liaison dépliés qui maintiennent le flotteur.The accompanying drawings illustrate the invention
Figure 1 shows in plan the edge of a main hull and two unfolded connecting arms which hold the float.

La figure 3 représente le profil d'un bras de liaison en position replié.Figure 2 shows the profile of an unfolded link arm
Figure 3 shows the profile of a link arm in the folded position.

En référence à ces dessins, le dispositifs comporte entre eux les tubes(l et 1dont l'angle d'articulation est donné par les bielles (3, 4 et 5)articulées en(A B, C, D; E, F,Gss

The proportion must be respected, between the lengths of the different tubes which constitute a connecting arm, as well as their fixing points.

La position du flotteur (H) une fois choisie, les articulations se trouvent bloquées par une bielle (6) de longueur variable mécaniquement, brochée entre(G et C ou E et F),Chaque bras de liaison est fixé sur le bord supérieur de la coque centrale en deux endroit, respectifs et précis. Le flotteur(H)est solidaire du tube,j2)et présente toujours en position navigation une section favorable. Les bras de liaisons gardent la position perpendiculaire à l'axe longitudinal de la coque principale grâce aux haubans(7 et
Le dispositif selon l'invention est particulièrement destiné à plier les bras de liaison d'un trimaran pour que les flotteurs se placent sur la coque centrale. The position of the float (H) once chosen, the joints are blocked by a rod (6) of mechanically variable length, pinned between (G and C or E and F), Each link arm is fixed on the upper edge of the central shell in two places, respective and precise. The float (H) is integral with the tube, j2) and always has a favorable section in the navigation position. The link arms keep the position perpendicular to the longitudinal axis of the main hull thanks to the shrouds (7 and
The device according to the invention is particularly intended to fold the link arms of a trimaran so that the floats are placed on the central hull.
