Description

The subject of the invention is an on-board device for recovery of a man overboard allowing self-recovery of a conscious victim.

• bouées de sauvetage, ronde,
• bouées en U ou en forme de fer à cheval,
• bouées en forme de triangles ou carrés, de divers matériaux rigides et gonflables.

The state of the art can be defined by the following material:

• lifebuoys, round,
• U-shaped or horseshoe-shaped buoys,
• buoys in the shape of triangles or squares, of various rigid and inflatable materials.

• engins de flottaison en volumes rectangulaires de différentes tailles comme les coussins de sauvetage des avions de ligne ou bien ceux plus gros des navires avec des cordes pour s'agripper,
• gilets de sauvetage en mousse rigide ou bien gonflable,
• combinaison de survie étanche et gonflable,
• canots de sauvetage de différentes tailles rigides ou gonflables, pouvant accueillir de une à plusieurs dizaines de personnes,
• matériel de signalisation personnelle : sifflets, miroirs, lampes, feux, colorants, émetteurs radio de positionnement par satellite, etc.

These buoys do not guarantee the flotation because the victim is involuntary and it may be that he did not put his buoy before falling or that there is no witness to launch one. Even if the victim has a buoy, she stays in the water while waiting for her rescue by outside help. It is the same for the material cited below:

• flotation devices in rectangular volumes of different sizes such as airbags for airliners or even larger ones for ships with ropes to grip,
• life jackets made of rigid or inflatable foam,
• waterproof and inflatable survival suit,
• lifeboats of various rigid or inflatable sizes, which can accommodate from one to several dozen people,
• personal signaling equipment: whistles, mirrors, lamps, lights, dyes, satellite positioning radio transmitters, etc.

Often when a victim falls into the sea, they do not carry none of the equipment mentioned above.

1 - fournir un équipement de flottaison,

2 - établir le contact physique avec la victime,

3 - ramener la victime à bord.

Studies by various organizations involved in safety at sea show that there are three critical steps in the rescue of a man overboard:

1 - provide flotation equipment,

2 - establish physical contact with the victim,

3 - bring the victim back on board.

Existing equipment, products or techniques for solve the problem, are incomplete because they fail on a or two steps leading to the rescue.

1) la flottaison : il existe la bouée de sauvetage (en forme d'anneau, de fer à cheval, etc.), les gilets de sauvetage en mousse rigides ou gonflables de n'importe quelle forme et même un radeau de survie gonflable, pour une personne et que la victime est supposée emporter avec elle dans sa chute. Les équipements cités fournissent la flottaison mais le contact avec le bateau qui continue sa course est perdu et cela ne permet pas de ramener la victime à bord. D'autres, offrent la possibilité de hisser la victime mais seulement dans le cas où celle-ci flotte à côté du bateau. Des perches sont destinées à marquer la position sur l'eau de la victime de même qu'une radio balise transmet par satellite sa position exacte mais échouent à deux des trois étapes critiques du sauvetage.Dans le cas d'un homme qui tombe à la mer, si celui-ci ne porte pas de gilet ou de bouée de sauvetage, il est impossible de garantir que les autres membres de l'équipage peuvent lui fournir un élément de flottaison. Si le marin est solitaire, il est sûr que personne ne lui viendra en aide immédiatement. Lorsque d'autres personnes sont à bord, il peut ne pas y avoir eu de témoin de la chute (exemple : le marin est de quart seul la nuit pendant que les autres dorment), les autres membres de l'équipage peuvent être dans l'impossibilité de manoeuvrer correctement le navire et revenir sur le point de chute pour fournir l'élément de flottaison. Il existe plusieurs raisons possibles.Donc, la seule solution pour qu'une victime flotte est qu'elle porte un gilet ou une bouée avant de tomber ou bien qu'il existe un élément de sauvetage dans l'eau, à côté de la victime que celle-ci puisse saisir immédiatement.

2) établir le contact avec la victime : Une victime solitaire ou sans témoin est perdue.Si la victime n'est pas reliée avec le bateau au moyen d'une corde, le contact physique est perdu et devra être établi à nouveau.Si un témoin éloigne le bateau en manoeuvrant, il lui est difficile de maintenir le contact visuel avec la victime. Un mécanisme automatique ou manuel peut lâcher sur l'eau un équipement de positionnement comme une perche avec un drapeau, une balise radio-satellite. De nuit, l'équipage perdra de vue la victime si celle-ci n'est pas munie d'une lampe de signalisation, de même la victime aura des difficultés à trouver une bouée de sauvetage si celle-ci n'est pas munie d'une lampe.Pour établir le contact, le bateau doit revenir et stopper exactement à l'endroit où se trouve la personne dans l'eau, ceci dans n'importe quelle condition. Il est extrêmement difficile de réaliser cette manoeuvre à la voile, parfois impossible par gros temps, vent fort et mer agitée. Si l'équipage arrive à manoeuvrer le bateau à proximité immédiate, cela met souvent la victime dans un péril plus grand que si le bateau maintenait une certaine distance.On peut tenter d'établir le contact en lançant une bouée attachée à une corde mais, pour que la victime s'en saisisse et l'enfile, il faut que celle-ci soit immobile sur l'eau sinon, elle sera arrachée des mains de ladite victime qui n'aura pas le temps de l'enfiler. Or ceci suppose que le bateau s'arrête.Par grand vent, il est impossible d'arrêter un voilier, particulièrement un multicoque qui va conserver une certaine vitesse sur l'eau. Si le contact est établi avec la victime par le moyen d'une corde, même si la victime a réussi à enfiler un gilet ou une bouée, elle va être traínée par le bateau qui continue à avancer. Or, avec plus de 70% du corps de l'eau, la résistance à l'avancement est telle que la victime est vite submergée et risque d'être noyée, l'obligeant ou obligeant les autres membres d'équipage à lâcher ladite corde, perdant ainsi le contact physique.Donc la seule solution pour établir le contact et de le garder est de fournir à la victime un élément de flottaison attaché au bateau, facile à saisir et qui n'offre pas de résistance à l'avancement dans l'eau quand la victime est traínée derrière un bateau.

3) ramener la victime à bord : Tous les équipements existants supposent une aide extérieure et ne conviennent pas au marin solitaire ou sans témoins capables de manoeuvrer dans la tempête.

For example :

1) flotation: there is the lifebuoy (ring-shaped, horseshoe-shaped, etc.), rigid or inflatable foam lifejackets of any shape and even an inflatable liferaft, for a person and that the victim is supposed to take with him in his fall. The aforementioned equipment provides buoyancy but contact with the boat which continues its course is lost and this does not allow the victim to be brought back on board. Others offer the possibility of hoisting the victim, but only in the event that the victim floats next to the boat. Poles are used to mark the victim's position on the water, as is a radio beacon which transmits his exact position by satellite but fails in two of the three critical stages of the rescue. In the case of a man who falls to the sea, if he does not wear a life jacket or life buoy, it is impossible to guarantee that the other members of the crew can provide him with a flotation element. If the sailor is lonely, he is sure that no one will help him immediately. When other people are on board, there may not have been any witness to the fall (example: the sailor is on watch alone at night while the others sleep), the other members of the crew may be in the water. '' inability to properly maneuver the vessel and return to the point of descent to provide the flotation element. There are several possible reasons, so the only solution for a victim to float is to wear a life jacket or buoy before falling or that there is a rescue element in the water, next to the victim. that it can immediately grasp.

2) establishing contact with the victim: A lone victim or one without a witness is lost. If the victim is not connected to the boat by means of a rope, physical contact is lost and must be established again. witness moves the boat away while maneuvering, it is difficult for him to maintain eye contact with the victim. An automatic or manual mechanism can drop positioning equipment on the water such as a pole with a flag, a radio-satellite beacon. At night, the crew will lose sight of the victim if the latter is not equipped with a signaling lamp, similarly the victim will have difficulty finding a lifebuoy if it is not equipped with a To make contact, the boat must come back and stop exactly where the person is in the water, under any condition. It is extremely difficult to carry out this maneuver under sail, sometimes impossible in heavy weather, strong wind and rough sea. If the crew manages to maneuver the boat in the immediate vicinity, this often puts the victim in greater danger than if the boat maintained a certain distance. We can try to establish contact by launching a buoy attached to a rope but, for the victim to grab it and put it on, it must be stationary on the water otherwise, it will be torn from the hands of said victim who will not have time to put it on. However, this supposes that the boat stops. In strong winds, it is impossible to stop a sailboat, especially a multihull that will keep a certain speed on the water. If contact is made with the victim by means of a rope, even if the victim has successfully put on a life jacket or buoy, he will be dragged by the boat which continues to move forward. However, with more than 70% of the body of water, the resistance to advancement is such that the victim is quickly submerged and risks being drowned, forcing him or forcing the other crew members to let go of said rope , thus losing physical contact, so the only solution for establishing and maintaining contact is to provide the victim with a buoyancy element attached to the boat, easy to grip and which does not offer resistance to advancement in the when the victim is dragged behind a boat.

3) bring the victim back on board: All the existing equipment supposes an external help and is not suitable for the lone sailor or without witnesses able to maneuver in the storm.

What works in wind and sea conditions calm like launching a buoy attached to a rope and pulling to bring the victim on board does not work if the boat does not stop. As described above, the resistance is such that the victim cannot be tanned on the rope. On the other hand, if the boat can stop next to the victim, it often results in greater danger than if the boat maintained a certain distance. When the edge of the ship is high and above water the victim must be able to be hoisted in a comfortable way, without danger, which supposes winching equipment.

So the only solution for the victim to come back on board for sure is that she can do it on her own. Likewise, the life-saving appliance must have hydrodynamic characteristics allowing the victim to be pulled by a rope, without resistance behind a boat and allowing this victim to tan or be pulled in return to the boat then above the water, on board.

Figure 15 is a schematic view of the operation of the flotation device and winching by the floating anchor.

The on-board self-recovery device of a man with conscious sea is of the type using a floating tip 1 such that shown in Figure 1, said floating end being connected to a buoyancy member 3, said buoyancy member 3 possibly containing safety and emergency equipment for rescue.

The trailing floating end 1 is intended to be recovered by man overboard because it acts as a command means for release the flotation element 3. Said flotation element 3 is itself connected to the boat 2 by an end acting as trailer 4.

This end serving as a trailer 4 is equipped with a means acting as a shock absorber 5. buoyancy member 3, said buoyancy member 3 possibly containing safety and emergency equipment for rescue.

The trailing floating end 1 is intended to be recovered by man overboard because it acts as a command means for release the flotation element 3. Said flotation element 3 is itself connected to the boat 2 by an end acting as trailer 4.

This end serving as a trailer 4 is equipped with a means acting as a shock absorber 5.

As shown in Figure 1, the three diagrams put in evidence that when victim 6 falls into the sea, the latter if conscious, can grab floating tip 1 and use the floating tip as a control means to trigger the release of the flotation element 3.

The victim 6 can then hoist himself on the element of waterline 3 and get down on your stomach and be dragged by the trailer 3, the element acting as a shock absorber can easily allow victim 6 to get into place without accoup in relation to towing the boat.

In the embodiment shown in Figure 2, the boat is equipped with a winch 7 with automatic release with control means such as the trailer.

The victim can thus initiate the winching maneuver from the flotation element 3.

The winch is arranged in such a way on the boat 2 that the winching operation of the floating element allows the lifting and recovery on board the flotation element 3 and victim 6 hanging on it.

According to the embodiment shown in Figure 3, the boat 2 is equipped with a launcher 8, said launcher 8 is controlled by the trailing floating end 1 which acts as control means to trigger the launch of a container

Figure 5 highlights the flotation element 3 which includes in particular a gripping element 10 which allows the victim 6 to use this handle as a stirrup to be maintained on the buoyancy element 3 in particular when the latter is towed and then lifted aboard the boat 2.

Figures 6 and 7 highlight the characteristics techniques of this flotation element which has in particular a hydrodynamic shape, close to that of a mattress or floating board, to carry all or part of the victim as shown in figure 7 and this, with a minimum resistance to water and wind when towing the buoyancy element 3 by the boat 2 since the latter 2 continues its course.

FIG. 10 represents a launcher 8 according to the device.

It is a barrel, the tube 11 of which is disposed on a support 12 with adjustable feet 13.

The support 12 receives the propellant which is actuated at by means of a gas reserve 15.

The base of the barrel is fixed by an adjustable clip 16.

The position of the various fixing rings 17 allows as well as adjusting the length of the feet 13, 14, to adjust the launch angle of the launcher.

The actuating trigger 25 is connected to the floating end trailing 1. In the tube 11 of the barrel is arranged the container 9 which has the shape of a warhead and which contains the element of buoyancy 3. Said buoyancy member 3 is itself connected to the trailer 4.

Figure 11 shows a winch 7 with its engine electric 29 which is actuated by a control lever 18 to which the trailer 4 is connected.

The winch 7 naturally includes a winding drum 19.

Figure 12 highlights a possible example of arrangement of the winch 7, of the trailer 4 of the flotation 3 folded.

The assembly is arranged at the level of the rail 20.

Winch 7 is at deck 21, while a support 22 is fixed to the rail 20 overboard and in a position above the winch 7.

This support 22 receives a protective packaging 23 for the trailer 4 which is coiled in said packaging 23 and which is connected at one end to the winch 7, while the other end is connected to the folded flotation element 3.

The buoyancy element 3 is placed in the support 22 in an unstable balance retained by a fragile cord 28 also connected by a ring 24 to the trailing floating end 1.

Victim 6's violent pull on the floating end dragging 1 breaks the cord 28, which causes the fall to the sea of the folded flotation element 3 which was in unstable equilibrium above water.

Flotation element 3 inflates automatically or not if it is inflatable and victim 6 can be towed in hanging on it.

Victim 6 can trigger his winching and lifting on board. that a shock absorber 5 is disposed between said pulley 33 and the attachment point on the rail 20.

As shown in Figure 14, pulling on the tip floating 1, the victim pulls on the quick coupler 35 which operates the pin 36 which releases the flyweight 37 and releases thus the device of his post. Quick coupler 35 opens by traction. The entire device falls into the water.

The carabiner 38 frees the floating board from the trailer 4.

Carabiner 39 is opened by the victim to release the floating anchor 30 which falls into the water.

Man fell overboard on floating board 3 can drop the anchor 30 which, by the speed of the boat and the return pulley, brings back according to arrow 1, said floating board 3 towards the boat.

According to these latter embodiments, the floating anchor 30 may not be connected to the double trailer 4 which passes through the pulley 33 but be attached to the floating board 3 in one other place.

In this case it is then the victim himself who strikes the floating anchor 30 on one end of the trailer (and not automatically) and then frees that end of the board buoyancy 3.
