Abstract

Method of protection of the hull of a boat against deposits due to the presence of marine animal or vegetable substances, during wintering, in which the hull is surrounded as far as the flotation line with the aid of an impermeable and opaque cover 6 secured to the deck of the boat. The seawater situated between the cover and the hull is removed and then a pocket of fresh water 12 is injected between the cover and the hull. Since the latter is sheltered from light and from the marine environment, no undesirable deposit comes to be fixed to it and the boat maintains its speed qualities.

Description

Dispositif de protection pour coque de bateau.Protective device for boat hull.

La présente invention concerne un dispositi de protection pour coque de bateau, plus particulièrement pour carène de bateau, destiné à éviter la formation de dép8ts végétaux ou animaux divers sur sa coque, notamment en période dthivernageO
On sait que lorsqu'une embarcation est destinée à demeurer longtemps immobile sur ou dans l'eau, en particulier l'eau de mer, par exemple durant l'liiver dans un port, une marina ou autre abri, divers dépôts marins recouvrent rapidement la carène de l'embarcation et imposent un nettoyage pério- dique fastidieux Si l'on veut conserver à la dite embarcation ses qualités de vitesse.
The present invention relates to a protective device for a boat hull, more particularly for a boat hull, intended to prevent the formation of various plant or animal deposits on its hull, especially during the wintering period.
It is known that when a boat is intended to remain immobile for a long time on or in the water, in particular sea water, for example during the winter in a port, marina or other shelter, various marine deposits quickly cover the hull of the boat and require tedious periodical cleaning If we want to keep the said boat its speed qualities.

Une première solution pour éviter de tels dépits consiste à hiverner le bateau au sec et éventuellement à l'abri, les inconvénients inhérents au contact statique avec l'eau de mer étant ainsi supprimés, mais fait appel à des moyens de transport du bateau onéreux ou encore absents des services portuaires mal equipés. En outre la location ou d'un espace approprié à terre est également onéreux.A first solution to avoid such losses consists of wintering the boat dry and possibly sheltered, the disadvantages inherent in static contact with sea water being thus eliminated, but calls for means of transport of the expensive boat or still absent from poorly equipped port services. In addition, renting or suitable land space is also expensive.

On connait également des peintures particulièrement destinées à la protection de la carène, dites "anti foulinge", qui permettent dtéviter de tels dépôts, et notament des peintures glycérophtaliques contenant des particules de cuivre en suspension. La toxicité de l'oxyde de cuivre qui se forme alors au contact de l'eau empoche la végétation ou les coquillages de se fixer sur la coque.Also known are paints particularly intended for the protection of the hull, called "anti fouling", which make it possible to avoid such deposits, and in particular glycerophthalic paints containing copper particles in suspension. The toxicity of the copper oxide, which then forms on contact with water, prevents vegetation or shells from settling on the hull.

On connait en outre des peintures encore plus toxiques.We also know of even more toxic paints.

Cependant cette solution présente quant à elle plusieurs inconvénients majeurs : tout d'abord ces peintures sont en général fragiles; ensuite leur efficacité est limitée dans le temps et un recarénage fréquent s'impose generale- ment; enfin c'est une solution qui, comme la première, est relativement onéreuse.However, this solution has several major drawbacks: first of all, these paints are generally fragile; then their effectiveness is limited in time and frequent recarenage is generally required; Finally, it is a solution which, like the first, is relatively expensive.

La présente invention vise à pallier ces inconvénients et à proposer un dispositif de protection de la coque qui soit à la fois simple à mettre en oeuvre et à installer sur le bateau avant l'hivernage, réutilisable à la fin d'un hivernage pour un éventuel hivernage ultérieur, et enfin peu onéreux et doté d'une bonne longévité.The present invention aims to overcome these drawbacks and to propose a hull protection device which is both simple to implement and install on the boat before wintering, reusable at the end of wintering for a possible subsequent wintering, and finally inexpensive and with good longevity.

A cet effet, la présente invention concerne un dispositif de protection pour coque de bateau, caractérisé par le fait qu'il comprend des moyens formant barrière entre le milieu marin et la coque et,entre les dits moyens et la coque, une poche d'eau douce. To this end, the present invention relates to a protective device for a boat hull, characterized in that it comprises means forming a barrier between the marine environment and the hull and, between said means and the hull, a pocket for pure water.

L'invention concerne également un procédé de protection pour coque de bateau, caractérisé par le fait que l'on dispose entre la coque et le milieu marin des moyens formant barrière, on évacue lteal de mer encore contenue entre la coque et les dits moyenq et on inJecte entre la coque et les dits moyens de l'eau douce.The invention also relates to a protection method for a boat hull, characterized in that, between the hull and the marine environment, there are barrier means, the sea lteal still contained between the hull and the said means is removed and fresh water is injected between the hull and the so-called means.

De façon préférée, les dits moyens formant barrière consistent en une toile en chlorure de polyvinyle dont la forme correspond sensiblement à celle de la coque du bateau.Preferably, said barrier means consist of a polyvinyl chloride fabric whose shape corresponds substantially to that of the hull of the boat.

I1 est avantageux que la toile soit opaque. En effet, les dépôts de végétaux sur la coque sont tres liés au phénomène de photosynthèse, notamment propice au développement des mousses. It is advantageous for the fabric to be opaque. Indeed, the deposits of plants on the hull are very linked to the phenomenon of photosynthesis, in particular favorable to the development of mosses.

En outre l'évacuation de l'eau de mer ainsi que l'injection d'eau douce seront de façon préférée effectuées au moyen d'une pompe. Cependant, dans les marinas équipées d'eau courante on pourra introduire directement un tuyau d'alimentation en eau douce dans la poche à remplir.In addition, the evacuation of sea water and the injection of fresh water will preferably be carried out by means of a pump. However, in marinas equipped with running water, a fresh water supply pipe can be directly introduced into the bag to be filled.

Enfin ,on pourra prévoir des moyens de contrôle de l'étanchéité de la toile, et par là de l'efficacité de la protection, moyens qui consistent en un témoin fait du mme matériau que la coque du bateau, immergé dans la poche d'eau douce. Ainsi7 si lton vérifie régulièrement qu'aucun dépôt n'a lieu sur le témoin, on s'assure que la coque reste également vierge de tout dépôt.Finally, it will be possible to provide means for checking the tightness of the fabric, and thereby the effectiveness of the protection, means which consist of a witness made of the same material as the hull of the boat, immersed in the pocket of pure water. Thus7 if lton regularly checks that no deposit takes place on the witness, we make sure that the shell also remains free of any deposit.

L'invention sera mieux comprise à la lecture de la description suivante d'une forme de réalisation préférée du dispositif et du procédé selon l'invention, faite en référence au dessin annexé dans lequel
- la figure 1 représente une coupe transversale d'un bateau équipé du dispositif selon l'invention, et
- la Figure 2 représente une vué latérale du bateau de la Figure 1 inclus les moyens de mise en oeuvre du procédé selon l'invention.
The invention will be better understood on reading the following description of a preferred embodiment of the device and the method according to the invention, made with reference to the appended drawing in which
FIG. 1 represents a cross section of a boat equipped with the device according to the invention, and
- Figure 2 shows a side view of the boat of Figure 1 including the means of implementing the method according to the invention.

Sur la Figure 1 est représentée très schématiquement la coque 2 d'un bateau 1 à propulsion par hélice. Le pont 3 du bateau est également schématiquement représenté. In Figure 1 is shown very schematically the hull 2 of a propeller-propelled boat 1. The deck 3 of the boat is also schematically represented.

Il comporte de façon conventionnelle des chandeliers 4 supportant une filière 5. Une toile ou housse 6 entoure la coque 2 jusqu'à une certaine hauteur au-dessus de la ligne de flottaison 7 du bateau, de 11 ordre de quelques dizaines de centimètres. La housse 6 comporte dans sa partie supérieure une série d'oeillets 8. Des cordages 9 traversant les oeillets et noués sur la filière 5 assurent le maintien en place de la housse tout autour de la coque.It conventionally comprises candlesticks 4 supporting a die 5. A canvas or cover 6 surrounds the hull 2 up to a certain height above the waterline 7 of the boat, of the order of a few tens of centimeters. The cover 6 has in its upper part a series of eyelets 8. Ropes 9 passing through the eyelets and knotted on the die 5 ensure that the cover is kept in place all around the shell.

Une drisse de renforcement 10, par exemple en nylon s'étend longitudinalement à l'intérieur de la housse sur la totalité de sa périphérie supérieure et est maintenue en place par une couture appropriée ou encore par collage. A reinforcement halyard 10, for example nylon, extends longitudinally inside the cover over its entire upper periphery and is held in place by an appropriate seam or by gluing.

te milieu ll environnant le bateau est de l'eau de mer.The middle of the boat is seawater.

La poche 12 située entre la toile formant barrière et la coque contient de l'eau douce qui y a été injectée par des moyens décrits par la suite. b élément 13 jouant le rôle de témoin est immergé dans la poche d'eau douce et est accroché à la filière 5 au moyen d'un filin 14 approprié. Te témoin étant soumis au même enviromlement que la coque, il permet, lorsqu'il est relevé et que l'on peut observer son aspect, d'indiquer si des dépôts sont ou non fixés sur la coque, et par là de vérifier que llétanchéité de la housse est satisfaisante.The pocket 12 located between the barrier fabric and the shell contains fresh water which has been injected therein by means described below. b element 13 playing the role of witness is immersed in the pocket of fresh water and is attached to the die 5 by means of a suitable rope 14. The witness being subjected to the same enviromlement as the hull, it allows, when it is raised and that one can observe its appearance, to indicate if deposits are fixed or not on the hull, and thereby to verify that the tightness of the cover is satisfactory.

On voit bien sur la Figure 2 que la housse est conformée de façon à entourer relativement étroitement la coque ainsi qu'un élément propulseur 15 situé à l'arrière.It can be seen in FIG. 2 that the cover is shaped so as to surround the shell relatively tightly as well as a propellant element 15 located at the rear.

Dans cette région, la housse présente une partie en creux 16. Au fond du dit creux est disposée l'extrémité d'un tuyau de reprise 17 dont l'autre extrémité est reliée à l'entrée d'une pompe 18 située sur le pont 3.In this region, the cover has a hollow part 16. At the bottom of said hollow is disposed the end of a return pipe 17, the other end of which is connected to the inlet of a pump 18 located on the bridge. 3.

Un second tuyau 19 relie la sortie de la pompe 18 à l'aau de mer, à l'extérieur de la toile 6.A second pipe 19 connects the outlet of the pump 18 to the seawater, outside the fabric 6.

Le procédé de mise en place du dispositif selon llinven- tion est le suivant : tout d'abord on met en place sous et autour de la coque 2 la housse ou toile 6.The process for installing the device according to the invention is as follows: first of all, the cover or canvas 6 is placed under and around the shell 2.

A cet effet la housse est avantageusement lestée à l'une de ses extrémités, par exenple l'extrémité avant Inverse-ment, la housse peut comporter à l'carrière un flotteur relié à la housse, un cordage approprié permets tant de faciliter la récupération de la housse en cas de fausse manoeuvre de l'utilisateur.For this purpose, the cover is advantageously weighted at one of its ends, for example the front end. Conversely, the cover may include a float connected to the cover at the quarry, suitable rope allows both to facilitate recovery. of the cover in the event of a false user operation.

On fixe tout d'abord l'extrémité arrière de la housse à la poupe, ou arrière, du bateau, au moyen des oeillets 8, des cordages 9 et de la filière ou liston 5 ; puis on passe la housse sous la coque, vers la proue, ou avant, le lestage Se a dite housse facilitant grandement cette opération; on assure alors 1e rwaint~en en place de la housse tout autour du bateau, également au moyen des cordages 9 traversant les oeillets 8 et noués sur la filière 5 ou sur des taquets 20, selon les cas.Firstly, the rear end of the cover is fixed to the stern, or rear, of the boat, by means of the eyelets 8, the ropes 9 and the die or liston 5; then we pass the cover under the hull, towards the prow, or before, ballasting Is said cover greatly facilitating this operation; we then ensure the 1st rwaint ~ in place of the cover all around the boat, also by means of ropes 9 passing through the eyelets 8 and knotted on the die 5 or on cleats 20, as the case may be.

Les tuyaux 17 et 19 étant disposés comme il a été décrit, on met alors en route la pompe 18. Ainsi, l'eau de mer encore contenue dans la poche située en-tre la housse et la coque est évacuée et refoulée dans le milieu marin environnant I1 est important que l'extrémité libre du tuyau de reprise 17 soit disposé au fond de la housse dans sa partie la plus basse, de façon à ce que la totalité de l'eau de mer soit effectivement évacuée.The pipes 17 and 19 being arranged as described, the pump 18 is then started up. Thus, the sea water still contained in the pocket located between the cover and the shell is evacuated and discharged into the medium surrounding seafarer I1 is important that the free end of the return pipe 17 is placed at the bottom of the cover in its lowest part, so that all of the sea water is effectively discharged.

A la fin de l'opération d'évacuation, on dispose la sortie d'un conduit d'alimentation en eau douce (non représenté) au fond de la housse, pour la remplir d'eau douce, la pompe 18 continuant à fonctionner jusqu'à ce quelle commence à refouler liteau douce. On interrompt le remplissage lorsque le niveau d'eau douce dans la poche a sensiblement atteint le niveau de la mer.At the end of the evacuation operation, there is the outlet of a fresh water supply duct (not shown) at the bottom of the cover, to fill it with fresh water, the pump 18 continuing to operate until 'to what she begins to repress soft batten. The filling is interrupted when the level of fresh water in the pocket has appreciably reached sea level.

A la fin des opérations, on obtient le dispositif de protection tel que décrit en référence à la figure l,et comportant donc une toile 6 formant barrière entre la coque et le milieu marin environnant, et, entre la toile et la coque, une poche 12 d'eau douce.At the end of the operations, the protective device is obtained as described with reference to FIG. 1, and therefore comprising a canvas 6 forming a barrier between the hull and the surrounding marine environment, and, between the canvas and the hull, a pocket 12 fresh water.

Notons que la toile est réalisée de préférence à partir de feuilles de chlorure de polyvinyle opaque dont la résistance et la longévité en milieu marin sont satis faisantes, l'opacité permettant d'éviter les phénomènes de photosynthèse favorisant l'apparition et le dépôt des mousses.La coque du bateau n'étant en contact qu'avec de l'eau douce, qui ne contient aucune substance végétale ou animale susceptible d'entraner l'apparition et le développement de dépôts, celle-ci restera propre pendant tout l'hivernage , comme l'indiquera le témoin 13 lors des vérifications. I1 est à noter que le dit témoin es-t avantageusement constitué du même matériau que la coqueS ce qui permet par son observation d'avoir une idée précise de l'état de la coque.Note that the canvas is preferably made from opaque polyvinyl chloride sheets whose resistance and longevity in the marine environment are satisfactory, the opacity making it possible to avoid photosynthesis phenomena favoring the appearance and deposition of mosses The hull of the boat being in contact only with fresh water, which does not contain any vegetable or animal substance likely to cause the appearance and the development of deposits, this one will remain clean during all the wintering , as witness 13 will indicate during the checks. It should be noted that the said witness is advantageously made of the same material as the shell which allows, by its observation, to have a precise idea of the state of the shell.

On a ainsi décrit un dispositif de protection tout à fait efficaceÊne pendant un hivernage prolongé, qui cependant reste peu onéreux, et dont le montage et le démontage, merle fréquents, sont simples à effectuer.A completely effective protection device has thus been described for a prolonged wintering, which however remains inexpensive, and whose assembly and disassembly, frequent robins, are simple to carry out.

En outre, le dispositif selon l'invention, apres un éventuel nettoyage de la toile, reste utilisable durant de nombreuses années.In addition, the device according to the invention, after possible cleaning of the fabric, remains usable for many years.

Bien entendu la présente invention n'est pas limitée à la description ci-dessus mais inclut également toutes les modifications que pourra y apporter l'homme de métier
en faisant appel à ses connaissances normales.
Of course, the present invention is not limited to the above description but also includes all the modifications that the skilled person may make to it.
using his normal knowledge.

En particulier les matériaux constituant les divers éléments, les divers moyens d'attache ainsi que les moyens
d'évacuation et d'injection des eaux pourront être modifiés sans sortir du cadre de 11 invention.
In particular the materials constituting the various elements, the various attachment means as well as the means
evacuation and injection of water may be modified without departing from the scope of the invention.

En outre, la présente invention stapplique aux bateaux monocoques, multicoques, à moteur ou à voile, par des modifications qui sont à la portée de l'Homme de l'Art. In addition, the present invention applies to monohull, multihull, motor or sailing boats, by modifications which are within the reach of those skilled in the art.
