Abstract

It is constituted by the combination of the mobility of the hull 12, capable of carrying out rotation through 180 DEG in both directions with the reversibility of the floats 4, 5 and of the mast assembly 17, 18. It is designed to allow itself to be raised solely by the efforts of the sailor of the vessel which has overturned.

Description

Dispositif d'auto redressement pour embarcation à coques multiples. Self-righting device for multiple hull craft.

I1 est destiné à permettre son relevage par l'interven- tion du seul navigateur du batîment qui a chaviré. It is intended to allow its lifting by the intervention of the only navigator of the vessel which has capsized.

Il est connu qu'une embarcation tels que les trimarans ou catamarans et similaires qui se sont retournés par suite d'intempéries ne peuvent plus se redresser par les propres moyens de l'équipage. It is known that a boat such as trimarans or catamarans and the like which have turned over as a result of bad weather can no longer recover by the crew's own means.

La plate-forme inversée très large, l'absence de lest, le mât jouant le rôle de quille inversée maintiennent l'embar- cation dans sa position périlleuse pour l'équipage qui doit l'abandonner et attendre qu'un ponton ou une grue de levage remette le navire en position normale, ce qui est aléatoire en plein océan. The very large inverted platform, the absence of ballast, the mast playing the role of inverted keel keep the boat in its perilous position for the crew who must abandon it and wait for a pontoon or crane lifting puts the ship in normal position, which is random in the open ocean.

L'objet de l'invention supprime ces inconvénients et permet à l'équipage, fut-il réduit à un seul homme de -rendre l'embarcation navigable à l'endroit comme à l'envers. Ce qui augmente les chances de survie dans des voyages transocéaniques. The object of the invention eliminates these drawbacks and allows the crew, even if it was reduced to a single man, to make the navigable boat upright and upside down. This increases the chances of survival on transoceanic voyages.

Il est constitué par la combinaison de la mobilité de la coque pouvant effectuer une rotation de 1800 dans les deux sens avec la reversibilité des flotteurs et de la mâture. It is made up of the combination of the mobility of the hull which can rotate 1800 in both directions with the reversibility of the floats and the mast.

Sur les dessins annexés, donnés à titre d'exemple non limitatif, d'une des formes de réalisation de l'objet de l'invention
La figure 1 représente le multi coque dans la position de renversement.
In the accompanying drawings, given by way of nonlimiting example, of one of the embodiments of the subject of the invention
Figure 1 shows the multi hull in the inverted position.

La figure 2 montre à une échelle réduite le redressement de la coque. Figure 2 shows on a reduced scale the straightening of the hull.

La figure 3 représente dans les mêmes conditions le multi coque redressé. FIG. 3 represents, under the same conditions, the straightened multi-hull.

La figure 4 est une vue à titre de comparaison d'un multi coque courant après renversement à 1800.  Figure 4 is a view for comparison of a multihull current after overturning in 1800.

Lorsqu une embarcation multi coque chavire (figure
L), la coque 1, les flotteurs Q, et le mât 3 formant quille s'opposent à tout redressement. L'équipage doit alors abandonner le navire et attendre des secours extérieurs.
When a multi-hull boat capsizes (figure
L), the hull 1, the floats Q, and the mast 3 forming a keel oppose any straightening. The crew must then abandon the ship and wait for outside help.

Le multi coque suivant l'invention tFig 1) comporte des flotteurs 4, 5 à profils sustentateurs 6, 7 symétriquement intégrés avec partie immergée 8, 9. The multihull according to the invention tFig 1) comprises floats 4, 5 with lift profiles 6, 7 symmetrically integrated with submerged part 8, 9.

Les structures formées par les bras 10, 10' sont reliées à l'armature ll qui forme berceau contenant la coque 12 montée sur arbres longitudinaux 13 de part et d'autre permettant son tourillonnement à 1800 dans les deux sens. The structures formed by the arms 10, 10 ′ are connected to the frame 11 which forms a cradle containing the shell 12 mounted on longitudinal shafts 13 on either side allowing it to be journalled at 1800 in both directions.

Des verins 14, 15 immobilisent la coque dans sa position horizontale, un lestage 16 peut être placé à la partie haute. Cylinders 14, 15 immobilize the hull in its horizontal position, a ballast 16 can be placed at the top.

La mature est formée par les montants 17, 18 reliés à leur extrémité 22 immobilisés par les paliers 19, 20 avec verrouillage au moyen de crémaillères circulaires dont le déverrouillage permet d' effectuer une rotation de 1800 dans les deux sens autour de leur arbre de support 10.The mature is formed by the uprights 17, 18 connected at their end 22 immobilized by the bearings 19, 20 with locking by means of circular racks whose unlocking allows a rotation of 1800 in both directions around their support shaft 10.

Lorsque le multi coque chavire en actionnant les verins 14, 15, on libère la coque de la structure rigide 11. La ditecoque effectue alors une rotation de 1800, flèche A (fig 2) et la cabine est automatiquement redressée par l'effet du lestage 16 qui prend la position basse. A ce moment on serre les verins pour l'immobiliser à nouveau. Les flotteurs 4, 5 étant automatiquement en état de flottabilité maximale. When the multi hull capsizes by actuating the jacks 14, 15, the hull is released from the rigid structure 11. The ditecoque then performs a rotation of 1800, arrow A (fig 2) and the cabin is automatically straightened by the effect of ballasting 16 which takes the low position. At this time we tighten the jacks to immobilize it again. The floats 4, 5 being automatically in a state of maximum buoyancy.

Les mâts immergés figure 2 ont la position B. Ils sont relevables par des moyens de levage réduits au minimum et sont mis dans la position C (fig 3). The submerged masts in Figure 2 have position B. They can be lifted by lifting means reduced to a minimum and are placed in position C (fig 3).

L'embarcation à coque multiple est ainsi redressée sans intervention de secours extérieurs et en état de navigabilité.  The multi-hull boat was therefore straightened without outside rescue assistance and in an airworthy condition.

Le lestage 16 renforçant en sa position basse la stabilité du navire sera automatiquement replacé dans sa position fonctionnelle en cas de nouveau chavirement (fig 1)
La structure centrale 11 sustentant la coque peut être réalisée en profilés métalliques à très haute résistance, n'entraînant en rien l'avancement de l'embarcation et augmentant même sa stabilité.
The ballast 16 reinforcing in its low position the stability of the vessel will be automatically returned to its functional position in the event of a new capsizing (fig 1)
The central structure 11 supporting the hull can be made of metal profiles with very high resistance, in no way leading to the advancement of the boat and even increasing its stability.

C'est pourquoi, les formes, dimensions et dispositions des différents éléments, pourront varier dans la limite des équi valent, comme d'ailleurs les matières utilisées pour leur fabrication, sans changer pour cela la conception générale de l'inven- tion qui vient d'être décrite. This is why, the shapes, dimensions and arrangements of the various elements, may vary within the limit of the equivalents, like, moreover, the materials used for their manufacture, without thereby changing the general conception of the invention which comes to be described.

C'est ainsi qu'il peut être utilisé un mat unique, soit solidaire de la coque, soit monté sur l i armature ou berceau.  Thus it can be used a single mast, either integral with the shell, or mounted on the frame or cradle.
