Description

La présente invention concerne un système de stockage et de largage d'un radeau de sauvetage pour navire et un navire comportant ledit système.The present invention relates to a system for storing and release of a life raft for a ship and a vessel containing the system.

Les navires modernes possèdent tous des systèmes de sauvetage sous la forme d'embarcations de sauvetage et sous la forme de radeaux gonflables.Modern ships all have life-saving systems in the form of lifeboats and in the form of rafts inflatable.

Suivant les types de navires et la réglementation applicable, le largage des embarcations de sauvetage ou des radeaux gonflables sera effectué en chute libre ou via des bossoirs.Depending on the types of vessels and the applicable regulations, the dropping out of lifeboats or inflatable rafts will be made in free fall or via davits.

Les embarcations de sauvetage sont de relativement grandes embarcations destinées à des navires importants comme les paquebots, ferrys... Elles sont généralement positionnées sur des berceaux, et des bossoirs installés à proximité servent à les mettre à l'eau.Lifeboats are relatively large boats intended for major ships such as steamers, ferries ... They are usually positioned on cradles, and davits installed nearby are used to launch them.

Généralement, les radeaux de sauvetage, le plus souvent du type gonflable, sont fixés sur un carlingage ou sur un berceau incliné servant de rampe. Le lancement des radeaux se fait alors par gravité suite à un déclenchement manuel ou par un largage hydrostatique.Generally, life rafts, usually of the type inflatable, are attached to a carling or inclined cradle serving as a ramp. The launch of the rafts is then done by gravity following a manual triggering or hydrostatic release.

Du fait de leur utilisation en cas de danger, ces systèmes de largage doivent être simples d'utilisation et extrêmement fiables, quelque soit l'environnement. A titre d'exemple, les réglementations prévoient qu'ils doivent fonctionner même si le navire gíte de 20°.Because of their use in the event of danger, these delivery systems must be easy to use and extremely reliable, whatever the environment. For example, regulations provide that they must operate even if the vessel is 20 °.

Pour répondre à ces contraintes, différents systèmes ont été développés. Ainsi, le brevet US 4,709,650 de Ingle décrit un radeau de sauvetage sous forme d'une sphère habitable qui repose sur un berceau fixe incliné. Le système comprend des moyens de retenue initiale du radeau et une rampe de chute qui pivote d'une position verticale de stockage vers une position inclinée permettant au radeau d'être largué par gravité.To meet these constraints, different systems have been developed. Thus, US Patent 4,709,650 to Ingle describes a raft of rescue in the form of a habitable sphere that rests on a fixed cradle inclined. The system includes initial raft restraint means and a drop ramp that pivots from a vertical storage position to a sloping position allowing the raft to be dropped by gravity.

Un autre système fonctionnant par gravité est celui décrit dans le brevet US 3,593,355 de R.E. Husband dans lequel une rampe de chute se déplie à partir d'une position verticale en accompagnement d'une rotation d'un berceau contenant le radeau.Another system operating by gravity is that described in US Pat. No. 3,593,355 to R. E. Husband in which a fall ramp unfolds from a vertical position along with a rotation of a cradle containing the raft.

Ces systèmes ont l'inconvénient d'être relativement complexes mécaniquement et donc de présenter un risque de dysfonctionnement et de mal s'intégrer dans les structures du navire ce qui occasionne des pertes de place importantes ainsi que des problèmes d'esthétique selon les types de navire.These systems have the disadvantage of being relatively complex mechanically and therefore present a risk of malfunction and harm integrate into the structures of the ship causing loss of space as well as aesthetic problems depending on the types of ship.

Le but de l'invention est donc d'obtenir un système mécaniquement simple et fiable s'intégrant dans les structures du navire de manière esthétique.The object of the invention is therefore to obtain a system mechanically simple and reliable integrating into the ship's structures in an aesthetic way.

Un navire, figure 1, comporte dans ses superstructures des systèmes de stockage et de largage de radeaux de sauvetage selon l'invention.A ship, Figure 1, has in its superstructures systems for storing and releasing life rafts according to the invention.

En référence à la figure 2, l'invention comporte un caisson 1 qui fait en général partie de la structure du navire ou qui en est solidaire.With reference to FIG. 2, the invention comprises a box 1 which makes generally part of the ship's structure or in solidarity with it.

Le caisson 1 comporte un châssis 2 fixe par rapport au reste de la structure du navire. Le châssis comporte une paroi verticale 2A orientée vers l'intérieur du navire et un fond 2B. La paroi 2A est équipée de préférence d'un système d'accès, non représenté, pour les membres d'équipage.The casing 1 comprises a frame 2 fixed relative to the rest of the ship structure. The frame has a vertical wall 2A oriented towards inside the ship and a 2B bottom. The wall 2A is preferably equipped with a access system, not shown, for crew members.

Une ouverture latérale 2C de largage du radeau est délimitée par le caisson 1. Cette ouverture 2C est tournée vers l'extérieur du navire. Une deuxième paroi 3 orientée vers l'extérieur du navire est prévue pour obturer l'ouverture 2C. Cette paroi 3 est mobile et bascule par rapport au caisson 1 horizontalement autour d'une charnière 4, positionnée sur le bord inférieur de celle-ci. Cette charnière 4 permet une rotation de la paroi 3 d'au maximum 180 degrés vers l'extérieur du navire, entre une position relevée de fermeture illustrée sur la figure 2 et une position abaissée de largage, illustrée sur la figure 3.A lateral release opening 2C of the raft is delimited by the caisson 1. This opening 2C is facing the outside of the ship. A second wall 3 facing the outside of the ship is intended to close the opening 2C. This wall 3 is movable and tilts with respect to the casing 1 horizontally around a hinge 4, positioned on the lower edge of it. This hinge 4 allows a rotation of the wall 3 of at most 180 degrees to the outside of the ship, between a closed up position illustrated in FIG. 2 and a lowered drop position, illustrated in FIG. 3.

La paroi mobile 3 est avantageusement intégrée dans les pavois du navire, comme illustré sur la figure 1.The movable wall 3 is advantageously integrated into the bulwarks of the ship, as shown in Figure 1.

Un dispositif de verrouillage 5 classique, maintient la paroi 3 en place.A conventional locking device 5 keeps the wall 3 in place. square.

Dans ce caisson 1, est installé un berceau 6 de support et de maintien d'un radeau de sauvetage 7. Ce radeau 7 se présente sous la forme classique d'un cylindre qui s'ouvre au contact de l'eau en deux moitiés pour libérer un canot gonflable.In this box 1, is installed a cradle 6 support and maintenance of a life raft 7. This raft 7 is in the form classic cylinder that opens on contact with water in two halves for release an inflatable canoe.

Le berceau 6 est équipé de cales 7A propres à maintenir le radeau 7 sur le berceau.The cradle 6 is equipped with wedges 7A adapted to maintain the raft 7 on the cradle.

Le berceau 6 est monté basculant par rapport au caisson 1 autour d'une charnière 8 à axe horizontal. Cette charnière est fixée sur le caisson 1 et se trouve à proximité de la charnière 4 de la paroi pivotante 3. La charnière 8 permet une rotation du berceau entre une position abaissée de stockage illustrée sur la figure 2 et une position relevée de largage du radeau illustrée sur la figure 3. La charnière est propre à autoriser un débattement angulaire supérieur à 20 degrés qui est la norme de gíte du navire à prendre en compte pour le fonctionnement des systèmes de sauvetage. Dans la pratique, cette rotation est de préférence supérieure à 45 degrés.The cradle 6 is mounted tilting relative to the casing 1 around a hinge 8 with horizontal axis. This hinge is fixed on the casing 1 and is close to the hinge 4 of the pivot wall 3. The hinge 8 allows rotation of the cradle between a lowered storage position illustrated in Figure 2 and a raised float release position shown on Figure 3. The hinge is suitable for allowing angular deflection greater than 20 degrees which is the norm of the ship's cottage to be taken into account for the operation of the rescue systems. In practice, this rotation is preferably greater than 45 degrees.

Le berceau 6 repose dans sa position de stockage parallèlement au fond 2B du caisson, maintenu d'une part par la charnière 8 et d'autre part par un système de vérin pneumatique 9 installé entre le berceau et le fond du caisson.The cradle 6 rests in its storage position parallel to the bottom 2B of the box, maintained on the one hand by the hinge 8 and on the other hand by a pneumatic cylinder system 9 installed between the cradle and the bottom of the caisson.

Ce système de vérin 9 est lui-même connecté à un système 11 de génération de gaz tel qu'un accumulateur d'azote, par l'intermédiaire d'un verrou de déclenchement connecté à un système hydrostatique 12 bien connu de l'homme du métier.This jack system 9 is itself connected to a system 11 of generation of gas, such as a nitrogen accumulator, via a trigger lock connected to a well known hydrostatic system 12 of the skilled person.

Le fonctionnement du système selon l'invention va maintenant être décrit en référence à la figure 2 sur laquelle le système est en position de stockage et à la figure 3 sur laquelle le système est en position de largage.The operation of the system according to the invention will now be described with reference to FIG. 2 on which the system is in a position of storage and in Figure 3 on which the system is in the release position.

Quand le radeau de sauvetage n'a pas besoin d'être utilisé, le système se trouve dans la position illustrée à la figure 2. La paroi mobile 3 ferme le caisson. Elle est maintenue en place par le dispositif de verrouillage 5. Le berceau 6 est dans une position sensiblement horizontale, le radeau 7 étant maintenu sur celui-ci par son propre poids par l'intermédiaire des cales 7A, éventuellement complétées par un sanglage amovible non représenté.When the life raft does not need to be used, the The system is in the position shown in Figure 2. The movable wall 3 close the box. It is held in place by the locking device 5. The cradle 6 is in a substantially horizontal position, the raft 7 being maintained on it by its own weight via wedges 7A, possibly supplemented by a removable strap not shown.

Quand le radeau doit être mis à la mer, le système de verrouillage 5 libère la paroi mobile 3.When the raft is to be put to sea, the locking system 5 releases the movable wall 3.

Le système de vérin 9 pousse alors le berceau 6 afin qu'il pivote autour de sa charnière 8.The jack system 9 then pushes the cradle 6 so that it pivots around its hinge 8.

Le basculement de la paroi mobile 3 après son déverrouillage est provoqué par le radeau 7 qui, lors de la rotation du berceau 6, pousse la paroi 3 jusqu'à son basculement.The tilting of the mobile wall 3 after unlocking is caused by the raft 7 which, during the rotation of the cradle 6, pushes the wall 3 until it tilts.

Le berceau 6 prolongé par la paroi 3 créent ainsi une rampe de chute pour le radeau comme illustré en figure 3.The cradle 6 extended by the wall 3 thus create a fall ramp for the raft as shown in Figure 3.

Le sanglage éventuel qui maintenait le radeau 7 ayant été retiré, celui-ci quitte, par simple gravité, son berceau 6 et glisse et/ou roule sur la rampe de chute en direction de la mer. The possible webbing that kept the raft 7 having been removed, it leaves, by simple gravity, its cradle 6 and slides and / or rolls on the drop ramp towards the sea.

Le système selon l'invention étant mécaniquement très simple garantit ainsi une haute fiabilité de son fonctionnement.The system according to the invention being mechanically very simple thus guarantees a high reliability of its operation.

Selon une variante représentée en figure 4, 5 et 6, la charnière 4 et la charnière 8 sont positionnées sur le même axe horizontal. Mais il est aussi possible de positionner la charnière 8 solidairement avec le berceau 6.According to a variant shown in FIGS. 4, 5 and 6, the hinge 4 and the hinge 8 are positioned on the same horizontal axis. But he is also possible to position the hinge 8 integrally with the cradle 6.

Un système de vérin 15 est installé entre lé berceau 6 et la paroi mobile 3. Par ailleurs, la paroi mobile 3 possède une butée 16 sur son bord inférieur.A jack system 15 is installed between the cradle 6 and the wall mobile 3. Moreover, the movable wall 3 has a stop 16 on its edge inferior.

Selon ce type de réalisation, la paroi basculante 3 effectue une rotation d'environ 135 degrés vers l'extérieur du navire de telle sorte que la butée 16 vienne en contact avec le berceau 6. La paroi 3 est ainsi sensiblement alignée avec le berceau 6.According to this type of embodiment, the rocking wall 3 performs a rotation about 135 degrees to the outside of the ship so that the stop 16 comes into contact with the cradle 6. The wall 3 is thus substantially aligned with the cradle 6.

Le système de vérin 15 a une double fonction dans ce mouvement. Dans un premier temps, il participe à la rotation de la paroi 3 jusqu'à ce que celle-ci, ayant dépassé la verticale, soit entraínée par son propre poids. Dans un second temps, en fin de mouvement, il amortit la rotation de la paroi 3 et participe à rendre le berceau 6 et la paroi 3 solidaires.The jack system 15 has a dual function in this movement. At first, it participates in the rotation of the wall 3 until this, having exceeded the vertical, is driven by its own weight. In a second time, at the end of the movement, it damps the rotation of the wall 3 and participates in making the cradle 6 and the wall 3 integral.

Le système étant alors dans la position représentée figure 5, le berceau 6 et la paroi mobile 3 forment un ensemble solidaire. Le système de vérin 9 pousse alors le berceau 6, ce qui entraíne la paroi 3, vers la position de largage, figure 6.The system then being in the position shown in FIG. cradle 6 and the movable wall 3 form an integral assembly. The system of cylinder 9 then pushes the cradle 6, which causes the wall 3, to the position of drop, figure 6.

Dans une autre variante, le berceau 6 est équipé d'un dispositif mécanique 13 de type butée ou vérin, propre à prendre appui et à pousser la paroi 3 pour provoquer son basculement lors de la rotation du berceau. Par rapport au mode de réalisation initial, cela a l'avantage de ne pas créer de contrainte sur le radeau de sauvetage 7.In another variant, the cradle 6 is equipped with a device mechanical 13 stop type or cylinder, able to support and push the wall 3 to cause its tilting when rotating the cradle. By compared to the initial embodiment, this has the advantage of not creating stress on life raft 7.

Par ailleurs, pour garantir un fonctionnement en toute circonstance, le vérin de poussée 9 est alimenté par l'accumulateur de gaz 11 sous pression. Ce gaz est alors libéré lorsque nécessaire, par la percussion du verrou qui, au repos, est maintenu en place par le système hydrostatique 12.In addition, to guarantee operation in all circumstances, the thrust cylinder 9 is fed by the gas accumulator 11 under pressure. This gas is then released when necessary, by the percussion of the lock which, at rest, is held in place by the hydrostatic system 12.

Il est aussi possible de remplacer l'accumulateur de gaz par une charge pyrotechnique 11 dont la combustion génère un gaz pour alimenter le vérin. It is also possible to replace the gas accumulator with a pyrotechnic charge 11 whose combustion generates a gas to fuel the cylinder.

En variante, la paroi mobile 3 bascule, après déverrouillage, sous l'action de son propre poids autour de l'axe de la charnière 4 pour atteindre sa position abaissée de largage quand la configuration du navire et en particulier celle du pavois et quand le centre de gravité de l'ensemble le permettent.As a variant, the mobile wall 3 switches, after unlocking, under the action of its own weight around the axis of the hinge 4 to reach its lowered position of drop when the configuration of the ship and in particular that of the bulwark and when the center of gravity of the whole allow it.

Les pavois étant souvent dans les navires des zones pas ou peu utilisées, l'installation de systèmes selon l'invention dans les pavois permet d'optimiser l'utilisation des espaces du navire. Et comme, la paroi mobile 3 est conçue pour s'intégrer aux pavois, cela permet de cacher les radeaux et de protéger le système des intempéries, augmentant ainsi sa fiabilité.The bulwarks being often in the ships of the zones not or little used, the installation of systems according to the invention in the bulwarks allows to optimize the use of the spaces of the ship. And as, the movable wall 3 is designed to integrate with the bulwarks, this allows the rafts to be hidden and protect the system from the weather, increasing its reliability.
