Description

ELEMENT GONFLABLE D'UN DISPOSITIF DE PROTECTION D'UNE COQUE INFLATABLE ELEMENT OF A HULL PROTECTION DEVICE
DE BATEAUBOAT
L'invention se rapporte à un élément gonflable d'un dispositif de protection d'une coque de bateau contre les chocs. Lorsqu'un bateau est amarré le long d'un ponton ou d'un quai, pour éviter de détériorer la coque, un dispositif de protection de la coque est placé en différents points le long du bord de la coque en regard du ponton.The invention relates to an inflatable element of a device for protecting a boat hull against impacts. When a boat is moored along a pontoon or a dock, to avoid damage to the hull, a hull protection device is placed at different points along the edge of the hull facing the pontoon.
Ce dispositif de protection se présente sous la forme d'un boudin vertical semi rigide maintenu suspendu par un cordage arrimé, par exemple au bastingage. Il est encore appelé pare battage.This protection device is in the form of a semi-rigid vertical coil held suspended by a rope stowed, for example to the rail. He is still called threshing fence.
Ce1S boudins rangés initialement dans le bateau doivent être mis en place manuellement lors de l'accostage puis rangés lors du déplacement en mer ou en rivière.This 1 S rolls initially stored in the boat must be set up manually during docking and then stored when traveling at sea or in the river.
Cette' manipulation étant fastidieuse et dangereuse, on connaît un dispositif DE-A- 297This manipulation being tedious and dangerous, a device DE-A-297 is known.
04 772 ou EP-A-0.987.176 qui consiste à aménager des logements dans la coque du bateau où sont logés des dispositifs gonflables de protection.04 772 or EP-A-0.987.176 which consists of arranging housing in the hull of the boat where are housed inflatable protection devices.
Chaque dispositif est constitué par une membrane élastique déformable de sorte que dégonflé, il peut être totalement logé dans le logement et en l'état gonflé, ce dispositif se présente sous la forme approximative d'une sphère. Chaque élément gonflable est monté amovible sur un embout, d'un circuit de gonflage/dégonflage, faisant sailli dans le logement.Each device is constituted by a deformable elastic membrane so that deflated, it can be completely housed in the housing and in the inflated state, this device is in the approximate form of a sphere. Each inflatable element is removably mounted on a nozzle, an inflation / deflation circuit, protruding into the housing.
Lors du gonflage, la déformation de la paroi du dispositif fait sortir le dispositif de protection.During inflation, the deformation of the wall of the device causes the protection device to come out.
Un tel système évite ainsi les manipulations et peut être géré à distance.Such a system thus avoids manipulation and can be managed remotely.
Ce système, qui présente des avantages, nécessite cependant que ces moyens soient prévus lors de la construction de la coque.This system, which has advantages, however, requires that these means are provided during the construction of the hull.
Un deuxième inconvénient est que ces moyens sont disposés à un niveau déterminé du bateau qui ne correspond pas nécessairement avec la hauteur du ponton ou du quai compte tenu de la marée.A second disadvantage is that these means are arranged at a specific level of the boat that does not necessarily correspond with the height of the pontoon or the wharf given the tide.
Un troisième point est que lors de l'accostage, ces dispositifs subissent des contraintes en cisaillement importantes qui tend à les arracher de leurs embouts.A third point is that during docking, these devices undergo significant shear stresses that tends to tear them off their tips.
Même en position stoppée du bateau, ces dispositifs travaillent en cisaillement. Dans ces exemples de solutions, la coque du bateau doit être percée et beaucoup de propriétaires refusent de faire ce trou.Even in the stopped position of the boat, these devices work in shear. In these examples of solutions, the hull of the boat must be pierced and many owners refuse to make this hole.
Par ailleurs sur certains bateaux, il est difficile de percer la coque.On some boats, it is difficult to pierce the hull.
On connait FR 2. 896. 227 un dispositif gonflable de protection d'une coque de bateau, ce dispositif comprenant un élément gonflable qui à l'état dégonflé se situe dans un logement et à l'état gonflé se trouve à l'extérieur de la coque, cet élément gonflable étant relié à un moyen de gonflage/dégonflage par une conduite. Il comprend, en outre, un moyen de manœuvre en translation déplaçant l'élément gonflable entre une position interne où il est logé dans une chambre tabulaire et une position externe avant de le gonfler. Ce produit est beaucoup plus pratique.FR 2. 896. 227 an inflatable device for protecting a boat hull is known, this device comprising an inflatable element which, in the deflated state, is located in a housing and in the inflated state is outside the hull, this inflatable element being connected to an inflating / deflating means by a pipe. It further comprises translational maneuvering means displacing the inflatable member between an internal position where it is housed in a tabular chamber and an external position before inflating it. This product is much more practical.
L'élément gonflable doit résister aux chocs. Il doit en outre être déformable suffisamment pour dans un premier temps être logé dans un tube de faible section et lorsqu'il est sorti de ce tube, occuper un volume important.The inflatable element must withstand shocks. It must also be sufficiently deformable to initially be housed in a small section tube and when it is out of this tube, occupy a large volume.
Pour que le pare battage soit efficace, il ne doit pas trop se déformer. Pour donner de la résistance à un ballon en caoutchouc, on peut y inclure, dans l'épaisseur de la membrane un treillis à la manière de ce qui se fait dans les tuyaux d'arrosage. Malheureusement cela réduit fortement l'élasticité du ballon et sa déformation.In order for the threshing device to be effective, it must not deform too much. To give resistance to a rubber balloon, one can include in the thickness of the membrane a lattice in the manner of what is done in the hoses. Unfortunately this greatly reduces the elasticity of the balloon and its deformation.
Une telle solution est impossible à mettre en œuvre avec un pare battage sauf à augmenter démesurément la section de la chambre logeant le pare battage quant il est rangé . Sachant que la place sur un bateau est limitée, cette solution ne convient pas.Such a solution is impossible to implement with a threshing device except to increase disproportionately the section of the chamber housing the threshing device when it is stored. Knowing that the place on a boat is limited, this solution is not suitable.
On peut également augmenter l'épaisseur de la paroi mais cela limite également la possibilité de déformation.It is also possible to increase the thickness of the wall but this also limits the possibility of deformation.
L'invention se propose d'apporter une solution. A cet effet, l'invention se rapport à un élément gonflable d'un dispositif de protection d'une coque de bateau caractérisé en ce que l'élément gonflable comprend une enveloppe déformable logée dans une poche souple en textile non solidarisée , la poche souple limitant l'amplitude de déformation de l'enveloppe déformable et définissant la forme de l'enveloppe déformable à l'état gonflé. L'invention sera bien comprise à l'aide de la description ci-après faite à titre d'exemple non limitatif en regard du dessin qui représente : FIG 1 : Un bateau avec le dispositif de protection en position sortie et gonflé FIG 2 : Un dispositif de protection en position rentrée vue de dessus du bateau FIG 3 : Vue en gros plan d'un élément gonflable en cours de gonflage. FIG 4 : Vue en gros plan d'un élément gonflable en cours de gonflage et montrant la poche souple à l'état déployé et l'enveloppe déformable à l'état semi gonflé.The invention proposes to provide a solution. For this purpose, the invention relates to an inflatable element of a device for protecting a boat hull, characterized in that the inflatable element comprises a deformable envelope housed in a flexible non-fastened textile pouch, the flexible pouch limiting the deformation amplitude of the deformable envelope and defining the shape of the deformable envelope in the inflated state. The invention will be better understood using the following description given by way of non-limiting example with reference to the drawing which represents: FIG 1: A boat with the protection device in the out-position and inflated FIG 2: A protection device in the up-and-down position of the boat FIG 3: Close-up view of an inflatable element during inflation. FIG 4: Close-up view of an inflatable element during inflation and showing the flexible bag in the deployed state and the deformable envelope in the semi-inflated state.
En se reportant au dessin, on voit un dispositif 1 gonflable de protection d'une coque de bateau. Ce dispositif doit être mis en place avant accostage du bateau au quai ou au ponton d'amarrage. Ce dispositif 1 de protection comprend un élément 100 gonflable mobile entre une position dite interne (figure 2) où il est dégonflé et se situe à l'intérieur d'un logement et une position dite externe (figure 1) où il se trouve le long de la face externe de la coque.Referring to the drawing, we see an inflatable device 1 for protecting a boat hull. This device must be put in place before docking the boat at the dock or mooring pontoon. This protection device 1 comprises an inflatable element 100 movable between a so-called internal position (FIG. 2) where it is deflated and is located inside a housing and a so-called external position (FIG. 1) where it is located along of the outer face of the hull.
Le dispositif de protection est logé, au moins en partie, dans un caisson 300 présentant un orifice 2 de passage. Ce caisson est à l'extérieur du bateau ou logé à l'intérieur. Sa dimension transversale est inférieure à la section de l'élément gonflable à l'état gonflé.The protective device is housed, at least in part, in a box 300 having a passage 2 orifice. This box is outside the boat or housed inside. Its transverse dimension is smaller than the section of the inflatable element in the inflated state.
Il sera de préférence totalement logé dans le caisson à l'exception du moyen de production d'énergie qui pourra être celui du bateau.. Une chemise 2A guide l'élément gonflable lors de la manœuvre de sortie. Ce caisson est fixé sur le pont 400 du bateau. Il sera de préférence fixé de sorte que l'élément gonflable soit sensiblement parallèle à Taxe longitudinal. On a prévu un plan incliné 50 pour guider l'élément gonflable vers l'extérieur. L'élément gonflable se déplace donc de son logement vers l'extérieur par translation et déplacement la téral pour basculer ensuite vers le bas. Pour le gonfler et le dégonfler, ce dispositif de protection est relié à un moyen 3 de gonflage/dégonflage par une conduite 4.It will preferably be completely housed in the box with the exception of the means of energy production that can be that of the boat .. A liner 2A guides the inflatable element during the output maneuver. This box is fixed on deck 400 of the boat. It will preferably be fixed so that the inflatable element is substantially parallel to the longitudinal axis. An inclined plane 50 is provided to guide the inflatable element outwards. The inflatable element therefore moves from its housing to the outside by translation and displacement the lateral to then tilt down. To inflate and deflate, this protection device is connected to a means 3 of inflation / deflation by a pipe 4.
On utilisera, par exemple, un compresseur 5 associé à une pompe 6 à vide avec accessoirement une réserve d'air comprimé. Ces différents moyens pour le gonflage/dégonflage seront avantageusement logés dans le caisson fixé sur le pont pour en faire un dispositif quasi autonome. Un distributeur permet de connecter le dispositif de protection sur le compresseur ou sur la pompe à vide.For example, use will be made of a compressor 5 associated with a vacuum pump 6 and, incidentally, a reserve of compressed air. These various means for inflating / deflating will advantageously be housed in the caisson fixed on the bridge to make it a quasi-autonomous device. A distributor allows the protection device to be connected to the compressor or the vacuum pump.
Le dispositif de protection comprend un moyen 7 de manœuvre en translation le déplaçant entre les deux positions précitées. Le corps gonflable 100 du dispositif est sorti du caisson avant d'être gonflé.The protective device comprises a means 7 for translational movement moving it between the two aforementioned positions. The inflatable body 100 of the device is out of the box before being inflated.
Le déplacement en translation du dispositif permet ainsi de le sortir du caisson et l'amener à l'extérieur à un niveau souhaité, c'est à dire plus ou moins bas par rapport au pont du bateau.The translational movement of the device thus allows the out of the box and bring it outside to a desired level, that is to say more or less low compared to the deck of the boat.
Lorsqu'il est complètement à l'extérieur du caisson, il peut alors être gonflé. Avantageusement, c'est la conduite 4 d'alimentation/évacuation de l'air du dispositif gonflable qui déplace l'élément gonflable 100 du dispositif de protection.When it is completely outside the box, it can then be inflated. Advantageously, it is the supply line 4 / air evacuation of the inflatable device that moves the inflatable element 100 of the protective device.
La conduite 4 doit donc pouvoir exercer une action de poussée et une action de traction.The pipe 4 must therefore be able to exert a thrust action and a traction action.
Pour que cette conduite puisse agir en poussée, elle coulisse dans une gaine 8 immobilisée à chaque extrémité.For this pipe to act in thrust, it slides in a sheath 8 immobilized at each end.
Cette conduite doit également être souple pour, par exemple, s'enrouler sur un tambour 9 mu par un moteur électrique.This pipe must also be flexible for, for example, to wind on a drum 9 mu by an electric motor.
Avantageusement, l'élément gonflable 100 du dispositif de protection est relié à la conduite 4 d'alimentation/évacuation par un raccord 11 permettant la rotation du dispositif par rapport à la conduite.Advantageously, the inflatable element 100 of the protective device is connected to the supply / discharge pipe 4 by a connector 11 allowing the device to rotate relative to the pipe.
Cette aspect est important car il permet de faire travailler l'élément gonflable du dispositif de protection en rotation et non pas en cisaillement.This aspect is important because it makes it possible to work the inflatable element of the protective device in rotation and not in shear.
De préférence, l'élément 100 gonflable du dispositif de protection est de forme allongée en sorte que mis en place à l'extérieur de la coque, il protège la coque sur une bonne hauteur.Preferably, the inflatable element 100 of the protective device is of elongate shape so that placed on the outside of the shell, it protects the hull on a good height.
Le dispositif de protection est constitué d'un corps IA central creux souple tel un tube souple métallique en acier inoxydable pourvu de perforations IC pour le passage d'air, ce tube étant entouré d'une enveloppe IB déformable.The protective device consists of a flexible hollow central IA body such as a flexible stainless steel metal tube provided with perforations IC for the passage of air, this tube being surrounded by a deformable envelope IB.
La figure 3 montre en pointillé le corps de l'élément gonflable, en trait plein l'enveloppe à l'état semi gonflé et en trait mixte l'enveloppe gonflée. L'élément gonflable comprend une enveloppe IB déformable logée dans une poche ID souple en textile, la poche ID souple limitant l'amplitude de déformation de l'enveloppe déformable.Figure 3 dashed the body of the inflatable element, solid line the envelope in the semi-inflated state and dotted line the inflated envelope. The inflatable element comprises a deformable envelope IB housed in a flexible textile ID pocket, the flexible ID pocket limiting the deformation amplitude of the deformable envelope.
L'enveloppe IB est non seulement déformable mais à l'état non gonflée elle occupe un faible volume permettant de la passer au travers de l'orifice 2 de passage. Elle est en élastomère. Sa souplesse et son élasticité permettent d'occuper une faible volume à l'état non gonflé pour son passage au travers de la chemise 2A et un grand volume à l'état gonflé. Cette poche ID est, par exemple en nylon tressé. Dans une forme de réalisation particulière, cette poche est en polyester haute ténacité faite en tricotage tabulaire. Elle est tabulaire avec diminution des extrémités. Elle va donc limiter la déformation de l'enveloppe déformable et permettre d'augmenter la pression dans l'enveloppe déformable. Cette poche souple définit donc la forme maximale qu'aura l'enveloppe déformable à l'état gonflé. La figure 4 montre la forme qu'aurait la poche ID à l'état gonflé de l'enveloppe IB déformable toutefois l'enveloppe déformable est présentée à l'état partiellement gonflé.The envelope IB is not only deformable but in the uninflated state it occupies a small volume to pass through the orifice 2 passage. It is made of elastomer. Its flexibility and elasticity allow to occupy a small volume in the uninflated state for its passage through the liner 2A and a large volume in the inflated state. This ID pocket is, for example braided nylon. In a particular embodiment, this pouch is made of high tenacity polyester made of tabular knitting. It is tabular with diminished extremities. It will therefore limit the deformation of the deformable envelope and allow to increase the pressure in the deformable envelope. This flexible pouch thus defines the maximum shape that will have the deformable envelope in the inflated state. Figure 4 shows the shape of the ID bag in the inflated state of the deformable envelope IB, however, the deformable envelope is presented in the partially inflated state.
A' l'état dégonflé, l'enveloppe déformable occupe peu de place et la surépaisseur de la poche souple est peu gênante. La désolidarisation de la poche par rapport à l'enveloppe déformable permet que l'ensemble non gonflé occupe un faible volume. Compte tenu du déplacement de l'ensemble poche ID et enveloppe déformable, cette poche est maintenue à ses deux extrémités sur l'enveloppe B ou sur la conduite 4 par une' colle, un lien ou un élastique. Cette poche souple n'est pas fixée sur la surface de l'enveloppe déformable car cette poche souple en limiterait la déformation. La conduite 4 d'alimentation comporte un élément résistant à la traction.In the deflated state, the deformable envelope takes up little space and the extra thickness of the flexible bag is not a problem. The separation of the pocket from the deformable envelope allows the non-inflated assembly occupies a small volume. In view of the displacement of the ID pocket and deformable envelope assembly, this pocket is held at its two ends on the envelope B or on the pipe 4 by an adhesive, a link or an elastic. This flexible pouch is not fixed on the surface of the deformable envelope because this flexible pouch would limit deformation. The feed pipe 4 comprises a tensile-resistant element.
La conduite 4 comporte, par exemple, une enveloppe métallique souple, par exemple, du type de celle utilisée pour le tube souple mais étanche ou encore cette conduite métallique peut loger une conduite plastique du type de celle utilisée pour les commandes pneumatiques. Un câble peut être utilisé pour donner de la résistance à la conduite 4. Cette conduite 4 d'alimentation doit présenter une bonne résistance à la traction car lorsque le dispositif de protection est sorti, il peut subir des efforts de traction non négligeables.The pipe 4 comprises, for example, a flexible metal casing, for example, of the type used for the flexible tube but waterproof or this metal pipe can accommodate a plastic pipe of the type used for pneumatic controls. A cable can be used to give resistance to driving 4. This supply line 4 must have good tensile strength because when the protective device is out, it can undergo significant tensile stresses.
Le fait de prévoir un raccord 11 permettant la rotation de l'élément gonflable limite les efforts sur la conduite à ceux principalement de tractions.The fact of providing a connector 11 allowing rotation of the inflatable element limits the forces on the pipe to those mainly pulls.
L'extrémité libre sera, éventuellement, plombée en sorte qu'elle peut assister le déplacement de l'élément gonflable du dispositif de protection dans le sens de la sortie. Il peut présenter localement une portée conique pour une bonne étanchéité qui pourrait être complétée par un joint. Ce poids maintient également le dispositif verticalement lorsqu'il est sorti par l'effet de gravité.The free end will be possibly leaded so that it can assist the displacement of the inflatable element of the protective device in the direction of the exit. It may locally have a conical bearing for a good seal that could be completed by a seal. This weight also holds the device vertically when it is out of gravity.
Schématiquement a été représenté, un verrouillage 13 en translation de la conduite d'alimentation.Schematically has been shown, a locking 13 in translation of the supply line.
Il peut s'agir d'un verrouillage en rotation du tambour sur lequel s'enroule la conduite d'alimentation mais aussi d'un système à pression.It may be a rotation locking of the drum on which the supply pipe is wound but also of a pressure system.
On peut y prévoir un indicateur de la longueur de déroulement du lien qui relie le dispositif de protection au tambour afin de connaître depuis un poste éloigné la position de l'élément gonflable par rapport au pont.There may be provided an indicator of the unwinding length of the link which connects the protective device to the drum in order to know from a remote station the position of the inflatable element relative to the bridge.
Ainsi depuis un point de commande, on peut mettre en place ces dispositifs de protection encore appelés pare-battages sans risquer de tomber à l'eau ce qui est très intéressant pour des personnes à mobilité réduite.Thus from a control point, we can put in place these protective devices still called fenders without the risk of falling into the water which is very interesting for people with reduced mobility.
Ces dispositifs seront répartis le long de la coque suivant les nécessités. Ils sont, de préférence, autonome c'est-à-dire que le propriétaire à simplement besoin de fixer le caisson sur le pont à proximité du bord et de brancher le courant électrique si le dispositif est motorisé. Bien évidemment, le système peut être manuel, le tambour est manœuvré à l'aide d'une manivelle. Le gonflage pouvant se faire à partir d'une réserve d'air comprimé remplie lorsque le bateau est à quai. These devices will be distributed along the hull as required. They are, preferably, autonomous that is to say that the owner simply need to fix the box on the bridge near the edge and connect the electric current if the device is motorized. Of course, the system can be manual, the drum is maneuvered using a crank. Inflation can be done from a supply of compressed air filled when the boat is docked.
