Definitions
- the present invention relates to improvements made to automatic emptying devices for boats, especially for life rafts, including a hole in the bottom of the boat and a substantially flexible sleeve located under the bottom of the boat by being tightly connected to the edge of the said hole.
- a dump device thus arranged has a fundamental drawback which lies in the lack of automatic operation. Indeed, also not as difficult as the maneuvers exposed above, they require minimal knowledge of the things of the sea from people in the boat. Gold, this condition is not met when the boat is a life raft collecting passengers from a ship transport which, in general, have no knowledge of things from the sea and are unable to operate properly, at the right time, such quick-drain device.
- an automatic emptying device which preserves as much as possible the structure simple and inexpensive of the known emptying device aforementioned, and which is capable of equipping all kinds lifeboats, including life rafts, including very large life rafts arming passenger ships (for example car ferries).
- a quick-drain device arranged in accordance to the invention is characterized in that said sleeve is equipped with flotation means arranged at a distance from its connection with the hole in the bottom of the boat, what, when there is no water in the boat, the flotation means raise the sleeve under the bottom of the boat, closing approximately said handle and water cannot enter the boat through the sleeve, while when water is present in the boat and brought back to the hole above, its weight forces on the sleeve to lower from from the bottom of the boat despite the presence of the means of flotation and water flows through the sleeve.
- the means of flotation are arranged at or near the end of the end of the sleeve, so that the hole in the handle in non-functional position is pressed against the bottom of the boat. It is also possible to do so that the flotation means are kept away from the end of the sleeve, which makes it part middle of the sleeve which is pressed against the bottom of the boat while its end hangs freely.
- the means of flotation consists of at least one pneumatic pocket; advantageously then, the pneumatic pocket is shaped as at least one hermetically sealed tube containing air and extending around the perimeter of the sleeve, or else preferred variant the pneumatic bag consists of two tubes each extending over a respective half of the periphery of the sleeve.
- the sleeve is, in the absence of water flow, flattened and present two faces joined against each other by being provided each of one of the above flotation tubes, the sleeve being flattened, in the raised position under the action of the means waterline, substantially flattened under the bottom of the boat: this gives a better seal sleeve obstruction in non-functional position.
- the sleeve can then be formed by a sheet of material flexible folded in half flat, the edges being secured to each other and the fold being marked; or, of simpler and more preferred, the sleeve is formed of two sheets of flexible material placed one against the other the other and joined to each other by their edges respective longitudinal ones.
- the orifice of the sleeve connected to the hole provided in the bottom of the boat is arranged laterally on the sleeve, so that the sleeve in non-functional position extends approximately parallel to the bottom; this makes it easier to raise the sleeve against the bottom of the boat under the action of flotation means outside the emptying phases; when emptying phases, the sleeve does not stretch drastically vertically below the bottom, but extends more or less
- the sleeve is advantageously made of material relatively soft synthetic.
- the sleeve opening secured to the hole in the bottom of the boat is equipped with a protective mesh, to prevent objects from the boat are driven by the water discharged.
- a life raft 1 has a sidewall 2 defined by example by two superimposed pneumatic tubes.
- a fund flexible 3 extends under the lower flange.
- the bottom 3 is provided with a hole 4 which can be preferably fitted with a protective mesh 5 of design suitable (for example of the so-called "duckbill" type) for retain objects.
- a sleeve 6 made of a flexible material, by example a synthetic material, not alterable in contact with Seawater.
- the sleeve 6 is equipped with flotation means 7 which, in the example illustrated in FIG. 1A, are located at its free end. So when the interior of the raft 1 does not contain water (case illustrated in fig. 1A), the flotation means 7 raise the sleeve 6 (here the free end of this sleeve) and apply it against the bottom 3 of the raft.
- the vertical upward push which is exerted on the flexible wall of the sleeve tends to flatten the sleeve while pressing it against the bottom 3, so that the sleeve is thus relatively closed and that the sea water does not can hardly penetrate the sleeve and flow back in the raft (balancing of the levels in the case of a loaded raft whose bottom is located below the level of the water).
- FIG 2 is shown a variant of embodiment which constitutes a preferred embodiment.
- the handle 6 has its connection orifice 10 (here equipped of the retaining mesh 4 in "duckbill" mentioned above) laterally, not axially.
- the sleeve 6 is connected to the bottom 3 by being plated against the bottom 3 over almost its entire length and deviating from hole 4 approximately parallel to the background 3.
- the sleeve 6 is formed in the form flattened in a way, on the one hand, to improve the faculty obturation of the sleeve in period of non-evacuation of water and, on the other hand, to simplify the structure of the sleeve and to facilitate its manufacture.
- the sleeve 6 is formed by a single sheet 13 of flexible material folded over on itself, with the two longitudinal edges 11 secured (for example welded or glued) to one another.
- the fold 12 can advantageously be crushed, so that the sleeve has a generally flattened shape with two faces 13 a (top side in fig. 3) and 13 b (bottom side visible through the trellis 4 in Figure 3).
- the sleeve is formed by joining, edge against edge, of two sheets of flexible material 13 a, 13 b in one 13a of which has been cut out the orifice 10.
- the flotation means 7 can be constituted in any suitable manner and / or in any suitable material: strip of floating material secured to the sleeve, pocket filled with air attached to the sleeve, etc.
- FIG. 3 also shown schematically in Figures 4A and 4B, there are two elongated air pockets 14 which extend respectively over the entire width of the faces 13 a, 13 b.
- These pockets 14 can be produced independently of the faces 13 a , 13 b and attached (for example glued or welded) thereon, or else consist of a flap at the end of the faces 13 a , 13 b suitable for trapping a certain air volume.
- the flotation means 7 are not necessarily arranged at the free end of round 6, but can just as easily be arranged to away from this end, as shown in Figure 5. It suffices that the flotation means 7 are located at distance from the connection of the sleeve 6 with the hole 4 of the bottom 3 of the raft.
Description
La présente invention concerne des perfectionnements apportés aux dispositifs vide-vite à fonctionnement automatique pour embarcation, notamment pour radeau de sauvetage, comprenant un trou pratiqué dans le fond de l'embarcation et une manche sensiblement souple située sous le fond de l'embarcation en étant raccordée de façon étanche au bord du susdit trou.The present invention relates to improvements made to automatic emptying devices for boats, especially for life rafts, including a hole in the bottom of the boat and a substantially flexible sleeve located under the bottom of the boat by being tightly connected to the edge of the said hole.
Il est bien connu dans l'état de la technique disponible au public avant la date de priorité de la présente invention des dispositifs vide-vite du genre précité dans lesquels la manche pend approximativement verticalement sous le fond de l'embarcation lorsqu'il s'agit d'évacuer l'eau embarquée. Toutefois, en dehors des phases de vidage, la manche ne peut pas être laissée dans cette configuration car elle offre à l'eau la possibilité de refluer dans l'embarcation ; en particulier, lorsque l'embarcation est chargée et que son fond s'étend alors en-dessous du niveau de l'eau environnante, la manche offrirait passage à l'eau refluant dans l'embarcation jusqu'à équilibrage des niveaux à l'intérieur étal'extérieur de l'embarcation.It is well known in the state of the art available to the public before the priority date of the present invention of vacuum emptying devices of the aforementioned genre in which the sleeve hangs approximately vertically under the bottom of the boat when it comes to evacuate the water on board. However, outside the phases emptying, the sleeve cannot be left in this configuration because it offers water the possibility of flow back into the boat; especially when the boat is loaded and its bottom then extends below of the surrounding water level, the sleeve would offer water flow back into the boat until balanced levels inside and outside the boat.
De ce fait, en dehors des phases de vidage, il est nécessaire de tirer la manche à l'intérieur de l'embarcation et de neutraliser son orifice d'une manière quelconque (étranglement avec un lien souple, enroulement de la manche sur elle-même, mise en place d'un bouchon, ...), avant d'achever le vidage de l'eau résiduelle par écopage.Therefore, outside the emptying phases, it is necessary to pull the sleeve inside the boat and neutralize its orifice in some way (throttling with a flexible link, winding of the sleeve on itself, fitting a plug, ...), before to complete the emptying of the residual water by scooping.
A l'inverse, l'évacuation de l'eau embarquée nécessite la mise en position fonctionnelle de la manche : dégagement de l'orifice et descente de la manche sous le fond de l'embarcation.Conversely, the evacuation of onboard water requires the functional positioning of the sleeve: release of the orifice and descent of the sleeve under the bottom of the boat.
Toutefois, un dispositif vide-vite ainsi agencé présente un inconvénient fondamental qui réside dans le défaut d'automaticité de son fonctionnement. En effet, aussi peu difficiles que soient les manoeuvres exposées plus haut, elles nécessitent une connaissance minimale des choses de la mer de la part des personnes situées dans l'embarcation. Or, cette condition n'est pas remplie lorsque l'embarcation est un radeau de sauvetage recueillant des passagers d'un navire de transport qui, d'une façon générale, n'ont aucune connaissance des choses de la mer et sont incapables de faire fonctionner correctement, au moment voulu, un tel dispositif vide-vite.However, a dump device thus arranged has a fundamental drawback which lies in the lack of automatic operation. Indeed, also not as difficult as the maneuvers exposed above, they require minimal knowledge of the things of the sea from people in the boat. Gold, this condition is not met when the boat is a life raft collecting passengers from a ship transport which, in general, have no knowledge of things from the sea and are unable to operate properly, at the right time, such quick-drain device.
Il existe donc actuellement une demande pressante pour un dispositif vide-vite à fonctionnement automatique, qui conserve dans toute la mesure du possible la structure simple et peu onéreuse du dispositif vide-vite connu précité, et qui soit de nature à équiper toutes sortes d'embarcations, notamment des radeaux de sauvetage, y compris des radeaux de sauvetage de très grande capacité armant des navires de transport de personnes (par exemple des car-ferries).There is therefore currently a pressing demand for an automatic emptying device, which preserves as much as possible the structure simple and inexpensive of the known emptying device aforementioned, and which is capable of equipping all kinds lifeboats, including life rafts, including very large life rafts arming passenger ships (for example car ferries).
A ces fins, un dispositif vide-vite agencé conformément à l'invention se caractérise en ce que ladite manche est équipée de moyens de flottaison disposés à distance de son raccordement avec le trou du fond de l'embarcation, ce grâce à quoi, lorsqu'il n'y a pas d'eau dans l'embarcation, les moyens de flottaison font remonter la manche sous le fond de l'embarcation en obturant approximativement ladite manche et l'eau ne peut pas pénétrer dans l'embarcation à travers la manche, tandis que, lorsque de l'eau est présente dans l'embarcation et est ramenée vers le trou précité, son poids force sur la manche à s'abaisser à partir du fond de l'embarcation malgré la présence des moyens de flottaison et l'eau s'écoule à travers la manche.For these purposes, a quick-drain device arranged in accordance to the invention is characterized in that said sleeve is equipped with flotation means arranged at a distance from its connection with the hole in the bottom of the boat, what, when there is no water in the boat, the flotation means raise the sleeve under the bottom of the boat, closing approximately said handle and water cannot enter the boat through the sleeve, while when water is present in the boat and brought back to the hole above, its weight forces on the sleeve to lower from from the bottom of the boat despite the presence of the means of flotation and water flows through the sleeve.
Il est possible de faire en sorte que les moyens de flottaison soient disposés à l'extrémité ou au voisinage de l'extrémité de la manche, ce qui fait que l'orifice de la manche en position non fonctionnelle est plaquée contre le fond de l'embarcation. Il est également posible de faire en sorte que les moyens de flottaison soient écartés de l'extrémité de la manche, ce qui fait que c'est une partie intermédiaire de la manche qui est plaquée contre le fond de l'embarcation tandis que son extrémité pend librement.It is possible to ensure that the means of flotation are arranged at or near the end of the end of the sleeve, so that the hole in the handle in non-functional position is pressed against the bottom of the boat. It is also possible to do so that the flotation means are kept away from the end of the sleeve, which makes it part middle of the sleeve which is pressed against the bottom of the boat while its end hangs freely.
Dans un mode de réalisation préféré, les moyens de flottaison consistent en au moins une poche pneumatique ; avantageusement alors, la poche pneumatique est conformée en au moins un boudin hermétiquement clos renfermant de l'air et s'étendant sur le pourtour de la manche, ou bien en variante préférée la poche pneumatique est constituée de deux boudins s'étendant chacun sur une moitié respective de la périphérie de la manche.In a preferred embodiment, the means of flotation consists of at least one pneumatic pocket; advantageously then, the pneumatic pocket is shaped as at least one hermetically sealed tube containing air and extending around the perimeter of the sleeve, or else preferred variant the pneumatic bag consists of two tubes each extending over a respective half of the periphery of the sleeve.
En combinaison avec cette dernière disposition, il est préférable de faire en sorte que la manche soit, en l'absence d'écoulement d'eau, de forme aplatie et présente deux faces accolées l'une contre l'autre en étant pourvues chacune d'un des susdits boudins de flottaison, la manche aplatie étant, en position relevée sous l'action des moyens de flottaison, sensiblement plaquée à plat sous le fond de l'embarcation : on obtient ainsi une meilleure étanchéité d'obstruction de la manche en position non fonctionnelle. Dans un exemple de fabrication simple et peu onéreux, la manche peut alors être formée par une feuille d'un matériau souple pliée en deux à plat, les bords étant solidarisés l'un à l'autre et la pliure étant marquée ; ou bien, de façon plus simple et préférée, la manche est formée de deux feuilles d'un matériau souple accolées à plat l'une contre l'autre et solidarisées l'une à l'autre par leurs bords longitudinaux respectifs.In combination with this last provision, it is best to make sure that the sleeve is, in the absence of water flow, flattened and present two faces joined against each other by being provided each of one of the above flotation tubes, the sleeve being flattened, in the raised position under the action of the means waterline, substantially flattened under the bottom of the boat: this gives a better seal sleeve obstruction in non-functional position. In a simple and inexpensive manufacturing example, the sleeve can then be formed by a sheet of material flexible folded in half flat, the edges being secured to each other and the fold being marked; or, of simpler and more preferred, the sleeve is formed of two sheets of flexible material placed one against the other the other and joined to each other by their edges respective longitudinal ones.
De préférence toujours, l'orifice de la manche raccordé au trou prévu dans le fond de l'embarcation est disposé latéralement sur la manche, de sorte que la manche en position non fonctionnelle s'étend approximativement parallèlement au fond ; on facilite ainsi le relèvement de la manche contre le fond de l'embarcation sous l'action des moyens de flottaison en dehors des phases de vidage ; lors des phaces de vidage, la manche ne s'étend pas rigoureusement verticalement sous le fond, mais s'étend plus ou moins Preferably always, the orifice of the sleeve connected to the hole provided in the bottom of the boat is arranged laterally on the sleeve, so that the sleeve in non-functional position extends approximately parallel to the bottom; this makes it easier to raise the sleeve against the bottom of the boat under the action of flotation means outside the emptying phases; when emptying phases, the sleeve does not stretch drastically vertically below the bottom, but extends more or less
La manche est avantageusement constituée en matière synthétique relativement souple.The sleeve is advantageously made of material relatively soft synthetic.
De façon souhaitable, l'orifice de la manche solidarisé au trou du fond de l'embarcation est équipé d'un treillis protecteur, afin d'éviter que des objets de l'embarcation soient entraínés par l'eau évacuée.Desirably, the sleeve opening secured to the hole in the bottom of the boat is equipped with a protective mesh, to prevent objects from the boat are driven by the water discharged.
L'invention sera mieux comprise à la lecture de la description détaillée qui suit de certains modes de réalisation préférés donnés uniquement à titre d'exemples nullement limitatifs. Dans cette description, on se réfère aux dessins annexés sur lesquels :

Dans la description qui suit, on va décrire le dispositif de l'invention plus spécifiquement en relation avec un radeau de sauvetage, notamment un radeau de grande capacité, car c'est dans cette application que l'invention semble devoir se révéler la plus intéressante, étant entendu toutefois qu'il s'agit uniquement d'un exemple non limitatif et que l'invention peut trouver application dans les radeaux de sauvetage de type différent, voire dans des embarcations autres que des radeaux de sauvetage.In the following description, we will describe the device of the invention more specifically in relation with a life raft, including a large life raft capacity, because it is in this application that the invention seems to be the most interesting, being understood however, this is only a non-limiting example and that the invention can find application in rafts different type of rescue, even in boats other than liferafts.
En se référant tout d'abord à la figure 1A, un
radeau de sauvetage 1 comporte un flanc latéral 2 défini par
exemple par deux boudins pneumatiques superposés. Un fond
souple 3 s'étend sous le boudin inférieur.Referring first to Figure 1A, a
Approximativement dans sa partie centrale, ou en
tout autre emplacement propre à constituer la partie la plus
basse, le fond 3 est muni d'un trou 4 pouvant être de
préférence équipé d'un treillis protecteur 5 de conception
appropriée (par exemple du type dit "bec de canard") pour
retenir les objets.Approximately in its central part, or in
any other suitable location to constitute the most
bottom, the
Au bord du trou 4 est solidarisé de façon étanche,
sous le fond 3, une manche 6 en un matériau souple, par
exemple un matériau synthétique, non altérable au contact de
l'eau de mer.At the edge of the
La manche 6 est équipée de moyens de flottaison 7
qui, dans l'exemple illustré à la figure 1A, sont situés à
son extrémité libre. Ainsi, lorsque l'intérieur du radeau 1
ne contient pas d'eau (cas illustré à la fig. 1A), les
moyens de flottaison 7 font remonter la manche 6 (ici
l'extrémité libre de cette manche) et l'appliquent contre le
fond 3 du radeau.The
En prévoyant des moyens de flottaison qui entourent
la manche 6, la poussée ascendante verticale qui s'exerce
sur la paroi souple de la manche tend à aplatir la manche
tout en la plaquant contre le fond 3, de sorte que la manche
se trouve ainsi relativement obturée et que l'eau de mer ne
peut pratiquement plus pénétrer dans la manche et refluer
dans le radeau (équilibrage des niveaux dans le cas d'un
radeau chargé dont le fond est situé en dessous du niveau de
l'eau).By providing means of flotation that surround
round 6, the vertical upward push which is exerted
on the flexible wall of the sleeve tends to flatten the sleeve
while pressing it against the
Lorsque de l'eau 8 a été embarquée dans le radeau
(fig. 1B), le propre poids de cette eau qui est ramené vers
le trou 5 agit par gravité sur la manche 6 pour abaisser
celle-ci qui s'étend alors approximativement verticalement
(ou tout au moins en position fortement inclinée) sous le
fond 3 : l'eau embarquée peut ainsi s'écouler (flèche 9) par
la manche 6 jusqu'à équilibrage du niveau de l'eau 8 à
l'intérieur du radeau avec le niveau de la mer. A ce moment,
aucun effort antagoniste ne s'oppose aux moyens de flottaison
7 et la manche 6 est ramenée contre le fond 3 du radeau.
Le reliquat d'eau 8 dans le radeau peut alors être évacué
par écopage.When
Grâce aux dispositions propres à l'invention,
l'élimination de la plus grande partie de l'eau embarquée 8
s'effectue de façon entièrement automatique, sans aucune
intervention des passagers du radeau. En dehors des périodes
d'évacuation de l'eau, la manche est positionnée, là encore
automatiquement, de façon que l'eau extérieure ne puisse pas
refluer dans le radeau.Thanks to the provisions specific to the invention,
elimination of most of the water on
A la figure 2 est représentée une variante de
réalisation qui constitue un mode de réalisation préféré.
Comme illustré de façon mieux visible à la figure 3, la
manche 6 présente son orifice de raccordement 10 (ici équipé
du treillis de retenue 4 en "bec de canard" précité)
latéralement, et non pas axialement. Il en résulte que, dans
la position de repos ou de non-évacuation illustrée à la
figure 2, la manche 6 se raccorde au fond 3 en étant plaquée
contre le fond 3 sur la quasi-totalité de sa longueur et en
s'écartant du trou 4 de façon approximativement parallèle au
fond 3.In Figure 2 is shown a variant of
embodiment which constitutes a preferred embodiment.
As illustrated more clearly in Figure 3, the
En outre, comme illustré aux figures 4A et 4B, il
est avantageux que la manche 6 soit constituée sous forme
aplatie de manière, d'une part, à améliorer la faculté
d'obturation de la manche en période de non-évacuation d'eau
et, d'autre part, à simplifier la structure de la manche et
à faciliter sa fabrication.Furthermore, as illustrated in FIGS. 4A and 4B, it
it is advantageous that the
Dans l'exemple de la figure 4A, la manche 6 est
formée par une feuille unique 13 de matériau souple pliée
sur elle-même, avec les deux bords longitudinaux 11 solidarisés
(par exemple soudés ou collés) l'un à l'autre. A
l'opposé, la pliure 12 peut avantageusement être écrasée, de
manière que la manche présente une forme générale aplatie
avec deux faces 13a (face de dessus sur la fig. 3) et 13b
(face de dessous visible à travers le treillis 4 sur la
figure 3).In the example of FIG. 4A, the
Dans l'exemple de la figure 4B, la manche est formée
par la solidarisation, bord contre bord, de deux feuilles de
matériau souple 13a, 13b dans l'une 13a desquelles a été
découpé l'orifice 10.In the example of Figure 4B, the sleeve is formed by joining, edge against edge, of two sheets of
Les moyens de flottaison 7 peuvent être constitués de toute façon appropriée et/ou en tout matériau approprié: bande d'un matériau flottant solidarisé à la manche, poche remplie d'air solidaire de la manche, etc.The flotation means 7 can be constituted in any suitable manner and / or in any suitable material: strip of floating material secured to the sleeve, pocket filled with air attached to the sleeve, etc.
Dans l'exemple de la figure 3, schématisé également
sur les figures 4A et 4B, il s'agit de deux poches d'air
allongées 14 qui s'étendent respectivement sur toute la
largeur des faces 13a, 13b. Ces poches 14 peuvent être
réalisées indépendamment des faces 13a, 13b et rapportées
(par exemple collées ou soudées) sur celles-ci, ou bien
constituées par un rabat de l'extrémité des faces 13a, 13b
propre à emprisonner un certain volume d'air.In the example of Figure 3, also shown schematically in Figures 4A and 4B, there are two
On notera que le fait d'adjoindre à chaque face 13a,
13b un lfotteur 14 indépendant de celui de la face opposée
et s'étendant sur sensiblement toute la largeur de la face
13a, 13b conduit à faire agir l'effort de flottaison sur
toute la largeur de la face et appliquer les deux faces 13a,
13b l'une contre l'autre avec une efficacité améliorée
conférant une étanchéité d'obturation suffisante pour
empêcher l'eau extérieure de refluer dans le radeau.Note that the fact to add to each
On conçoit également que les moyens de flottaison 7
ne sont pas impérativement disposés à l'extrémité libre de
la manche 6, mais peuvent tout aussi bien être disposés à
l'écart de cette extrémité, comme illustré à la figure 5. Il
suffit que les moyens de flottaison 7 soient situés à
distance du raccordement de la manche 6 avec le trou 4 du
fond 3 du radeau.It can also be seen that the flotation means 7
are not necessarily arranged at the free end of
