Description

La présente invention concerne une embarcation de plaisance, qui peut être à voile ou à moteur, conçue pour d'une part la navigation et d'autre part l'observation des fonds marins.The present invention relates to a pleasure craft, which may be sail or motor, designed for navigation on the one hand and on the other hand the observation of the seabed.

Jusqu'à présent, les embarcations équipées de moyens pour observer le milieu marin ne sont que des embarca­tions scientifiques, à part celles, à fond plat, qui possèdent un fond transparent. On connaît également des structures fixes immergées à demeure, à l'intérieur desquelles les observateurs peuvent descendre et observer au travers de hublots la faune et la flore aquatiques environnantes.Until now, boats equipped with means for observing the marine environment have only been scientific boats, apart from those with flat bottoms, which have a transparent bottom. There are also known permanently immersed fixed structures, inside which observers can descend and observe through portholes the surrounding aquatic flora and fauna.

La présente invention entend proposer une embarcation qui permette d'une part de naviguer à l'instar d'une embarcation normale, et ce durant plusieurs jours compte tenu de l'équipement intérieur que peut comporter cette embarcation, et d'autre part soit de l'immobiliser, soit de réduire sa vitesse pour obtenir un poste d'observa­tion du milieu marin.The present invention intends to propose a boat which allows on the one hand to navigate like a normal boat, and this for several days taking into account the interior equipment that this boat can contain, and on the other hand either immobilize it, or reduce its speed to obtain a marine environment observation post.

L'invention permet donc d'allier les plaisirs de la navigation en tant qu'embarcations de promenade et de loisirs pour toutes croisières et les plaisirs de l'observa­tion du lieu où la flore et la faune sont particulièrement développées. Elle peut aussi constituer, dans des utilisa­tions spécifiques, une bulle de repérage ou de surveillance pour, par exemple, des écoles de plongée.The invention therefore makes it possible to combine the pleasures of navigation as pleasure and leisure boats for all cruises and the pleasures of observing the place where the flora and fauna are particularly developed. It can also constitute, for specific uses, a location or surveillance bubble for, for example, diving schools.

A cet effet, l'invention a donc pour objet une embarcation de plaisance comportant une coque à fond plat. Selon une caractéristique importante de l'invention, cette embarcation comporte un puits sensiblement au centre du fond de la coque, dans lequel est monté à coulissement un élément cylindrique comportant dans sa paroi latérale au moins un hublot, fermé à son extrémité inférieure, et un dispositif de manoeuvre de l'élément cylindrique dans le puits, entre une première position dans laquelle la paroi extérieure de ladite extrémité fermée est sensiblement au niveau du fond de la coque, et une seconde position dans laquelle ladite extrémité est éloignée dudit fond vers le bas, d'une distance permet­tant audit hublot d'être situé sous la coque.To this end, the invention therefore relates to a pleasure craft comprising a hull with a flat bottom. According to an important characteristic of the invention, this boat comprises a well substantially in the center of the bottom of the hull, in which is slidably mounted a cylindrical element comprising in its side wall at least one porthole, closed at its lower end, and a device for operating the cylindrical element in the well, between a first position in which the outer wall of said closed end is substantially at the bottom of the hull, and a second position in which said end is moved away from said bottom, by a distance allowing said porthole to be located under the hull.

Dans un mode de réalisation préféré, le disposi­tif de manoeuvre est constitué par un dispositif vis-écrou dont la vis est solidaire d'un élément de structure de la coque et est accouplée à un moto-réducteur d'entraînement en rotation tandis que l'écrou est solidaire de l'élément cylindrique.In a preferred embodiment, the operating device is constituted by a screw-nut device, the screw of which is integral with a structural element of the shell and is coupled to a geared motor for rotation while the nut is integral with the cylindrical element.

L'élément cylindrique comportera avantageusement un lest en sa partie inférieure, de manière que sa position de repos soit sensiblement à mi-course entre les deux posi­tions d'extrémité susdites.The cylindrical element will advantageously include a ballast in its lower part, so that its rest position is substantially halfway between the two abovementioned end positions.

Enfin, la section de l'élément cylindrique sera avantageusement elliptique, le grand axe de cette ellipse étant orienté dans le sens d'avancement de l'embarcation.Finally, the section of the cylindrical element will advantageously be elliptical, the major axis of this ellipse being oriented in the direction of advancement of the boat.

L'invention sera mieux comprise au cours de la description donnée ci-après à titre d'exemple purement indicatif et non limitatif qui permettra d'en dégager les avantages et les caractéristiques secondaires.
Il sera fait référence aux dessins annexés dans lesquels :

  • - la figure 1 est une vue en prespective arrachée d'une embarcation conforme à l'invention,
  • - la figure 2 est une coupe transversale de cette embarcation, avec une variante de réalisation illustrant les deux positions extrêmes de l'élément cylindrique d'obser­vation du milieu marin.
The invention will be better understood during the description given below by way of purely indicative and nonlimiting example which will make it possible to identify the advantages and the secondary characteristics thereof.
Reference will be made to the appended drawings in which:
  • FIG. 1 is a perspective view cut away from a boat according to the invention,
  • - Figure 2 is a cross section of this boat, with an alternative embodiment illustrating the two extreme positions of the cylindrical element for observing the marine environment.

En se reportant à ces figures, on voit que l'embar­cation, qui est ici prévue motorisée, comporte une coque 1 dont le fond 2 est plat et pourvu d'un lest.Referring to these figures, we see that the boat, which is here provided motorized, has a hull 1 whose bottom 2 is flat and provided with a ballast.

L'espace intérieur avant de la coque 1 est occupé par une couchette 3 alors que l'espace intérieur arrière est occupé par le groupe moteur 4 commandant l'hélice 5 et auquel est articulé le gouvernail 6 commandé par la barre 7. Entre l'espace avant 3 et l'espace arrière 4, la coque comporte une cabine 8 recouverte d'un toit 9.The interior space before the hull 1 is occupied by a berth 3 while the interior space aft is occupied by the engine group 4 controlling the propeller 5 and to which is articulated the rudder 6 controlled by the bar 7. Between the front space 3 and rear space 4, the hull comprises a cabin 8 covered with a roof 9.

La cabine est divisée principalement en deux espa­ces, un premier espace latéral et arrière 10 dans lequel on trouvera des équipements utilitaires tels que des plaques chauffantes ou un évier et des toilettes, et un espace central 11, séparé de l'espace 10 par une cloison verticale 12 qui constitue le prolongement au moins partiel d'un puits 13 ménagé dans le fond 2 de la coque 1.The cabin is mainly divided into two spaces, a first lateral and rear space 10 in which one will find utility equipment such as hot plates or a sink and toilet, and a central space 11, separated from space 10 by a partition vertical 12 which constitutes the at least partial extension of a well 13 formed in the bottom 2 of the shell 1.

A l'intérieur de cet espace 11 un élément cylin­drique 14 est monté à coulissement dans le puits 13 et guidé dans son coulissement par l'intermédiaire de guides 15 coopérant avec des galets 16 solidaires de la périphérie supérieure de l'élément cylindrique 14.Inside this space 11 a cylindrical element 14 is slidably mounted in the well 13 and guided in its sliding by means of guides 15 cooperating with rollers 16 integral with the upper periphery of the cylindrical element 14.

Cet élément cylindrique 14, qui sera appelé nacelle ultérieurement, comporte un fond 14a fermé dans lequel sont ménagés des compartiments de lestage 17. Ces comparti­ments 17 sont situés à la périphérie du fond 14a de manière à constituer des banquettes autour de l'espace intérieur de l'élément 14. On notera sur les figures que la section de cet élément 14 cylindrique est elliptique avec son grand axe orienté le long de l'axe de l'embarcation. On voit que la paroi latérale 18 de la nacelle 14 est équipée de quatre hublots 19 qui, lorsque la nacelle est en saillie par rapport à la coque 1, sont situés sous cette coque et permettent l'observation de milieux marins situés sous le bateau, comme le montre la partie de gauche de la figure 2. Cette partie de gauche illustre d'ailleurs l'une des positions extrêmes que peut prendre la nacelle par rapport à la coque 1, la partie de droite de la figure 2 illustrant l'autre des positions extrêmes de la nacelle par rapport à la coque, dans laquelle le fond 14a est sentiblement dans le plan du fond 2 de la coque.This cylindrical element 14, which will be called a nacelle later, has a closed bottom 14a in which ballast compartments 17 are provided. These compartments 17 are located at the periphery of the bottom 14a so as to constitute benches around the interior space of element 14. It will be noted in the figures that the section of this cylindrical element 14 is elliptical with its major axis oriented along the axis of the boat. It can be seen that the side wall 18 of the nacelle 14 is equipped with four portholes 19 which, when the nacelle projects from the hull 1, are located under this hull and allow the observation of marine environments located under the boat, as shown in the left part of FIG. 2. This left part also illustrates one of the extreme positions that the nacelle can take relative to the hull 1, the right part of FIG. 2 illustrating the other extreme positions of the nacelle relative to the hull, in which the bottom 14a is appreciably in the plane of the bottom 2 of the hull.

Un mécanisme permettant la manoeuvre de la nacelle entre ces deux positions est constitué par un dispositif vis-écrou comportant une vis 30 attelée au toit 9 de la cabine et capable de tourner dans un palier fixe, entraînée par un groupe moto-réducteur 31. La nacelle 14 comporte quant à elle une colonne centrale 32 qui porte un ecrou fixe coopérant avec la vis à sa partie supérieure non repré­senté qui, lorsque la vis 30 tourne, se déplace en transla­tion le long de celle-ci et entraîne la montée ou la descente de la nacelle. La vis est de préférence logée dans un four­reau fixe 33 dans laquelle l'extrémité supérieure de la colonne creuse 32 pourvue de l'écrou peut évoluer. La vis n'est donc jamais découverte.A mechanism for maneuvering the nacelle between these two positions is constituted by a screw-nut device comprising a screw 30 coupled to the roof 9 of the cabin and capable of turning in a fixed bearing, driven by a geared motor group 31. The basket 14 includes as for a central column 32 which carries a fixed nut cooperating with the screw at its upper part, not shown, which, when the screw 30 rotates, moves in translation along the latter and causes the nacelle to go up or down. . The screw is preferably housed in a fixed sleeve 33 in which the upper end of the hollow column 32 provided with the nut can evolve. The screw is therefore never discovered.

Dans un autre mode de réalisation visible sur la figure 2, ce dispositif de manoeuvre est constitué par un étrier 20 qui comporte deux branches 20a et 20b et un axe 21. Les branches 20a et 20b sont solidaires de l'axe 21 qui peut tourner dans des paliers 22 appartenant à la structure du bateau. Sous l'effet d'un vérin hydraulique 23, l'étrier 20 peut pivoter dans les paliers 22. Chaque bras 20a et 20b possède une lumière longitudinale extrême dans laquelle un axe 24 porté transversalement et extérieure­ment par la nacelle 14, peut coulisser. Ainsi, lorsque les bras pivotent, la nacelle est abaissée ou relevée par le vérin 23 et l'étrier 20. On notera que le lest est tel que la position de repos de la nacelle correspond à une position intermédiaire entre les positions haute et basse illustrées par la figure 2 , c'est-à-dire pour une position de l'étrier sensiblement horizontale. Cette disposition permet d'utiliser un vérin 23 de puissance moins importante que s'il n'existait pas de lest. Chacune des positions extrêmes de la nacelle est, du fait de ce lest, obtenue par action positive du vérin.In another embodiment visible in FIG. 2, this operating device consists of a stirrup 20 which has two branches 20a and 20b and an axis 21. The branches 20a and 20b are integral with the axis 21 which can rotate in bearings 22 belonging to the structure of the boat. Under the effect of a hydraulic cylinder 23, the stirrup 20 can pivot in the bearings 22. Each arm 20a and 20b has an extreme longitudinal lumen in which an axis 24 carried transversely and externally by the nacelle 14, can slide. Thus, when the arms pivot, the nacelle is lowered or raised by the jack 23 and the stirrup 20. It will be noted that the ballast is such that the rest position of the nacelle corresponds to an intermediate position between the high and low positions illustrated by Figure 2, that is to say for a substantially horizontal stirrup position. This arrangement makes it possible to use a jack 23 of lesser power than if there was no ballast. Each of the extreme positions of the nacelle is, because of this ballast, obtained by positive action of the jack.

L'espace intérieur de la nacelle est ici équipé d'une table 25, occupant le centre du fond 14a et entourée par la banquette aménagée au-dessus des compartiments de lest 17. On notera que la table 25 est montée sur une colonne télescopique 26.The interior space of the nacelle is here equipped with a table 25, occupying the center of the bottom 14a and surrounded by the bench arranged above the ballast compartments 17. It will be noted that the table 25 is mounted on a telescopic column 26 .

L'accès à l'espace intérieur de la nacelle 14, lorsque celle-ci est en position basse, se fait par une échancrure 12a de la paroi 12, que l'on peut franchir à partir de l'espace 10 de la cabine 8 au moyen d'une échelle 27, tandis qu'une échelle permet, à partir de cette échan­crure, d'atteindre le fond de la nacelle.Access to the interior space of the nacelle 14, when the latter is in the low position, is by a notch 12a of the wall 12, which can be crossed at from the space 10 of the cabin 8 by means of a ladder 27, while a ladder makes it possible, from this notch, to reach the bottom of the nacelle.

On peut également atteindre l'intérieur de la nacelle lorsque celle-ci est en position haute. Dans ce cas, en remontant, le bord supérieur de la nacelle entraîne l'élément supérieur 27a de l'échelle 27 qui se déplie téles­copiquement, l'échelle interne étant, quant à elle, immobile par rapport à la nacelle. On remarquera qu'il est alors nécessaire d'ouvrir le toit 9 au moyen des éléments télesco­piques de couverture 9a qu'il comporte pour pouvoir accéder à l'intérieur de la nacelle en position haute.One can also reach the interior of the nacelle when it is in the high position. In this case, going up, the upper edge of the nacelle drives the upper element 27a of the ladder 27 which unfolds telescopically, the internal ladder being, for its part, immobile relative to the nacelle. It will be noted that it is then necessary to open the roof 9 by means of the telescopic cover elements 9a which it comprises in order to be able to access the interior of the nacelle in the high position.

Sur la figure 2 on a marqué en F1 la ligne de flottaison de l'embarcation lorsque la nacelle est rétractée à l'intérieur de la coque, et la ligne F2 de flottaison lorsque la nacelle est en position sortie. On remarque que, dans ce cas, la ligne F2 est toujours à un niveau inférieur au niveau d'extrémité de la nacelle 14. Dans ces conditions, les remontées d'eau à l'intérieur de la nacelle sont impossibles. La variation de la ligne de flot­taison nacelle rentrée et nacelle sortie illustre l'intérêt d'avoir lesté la coque 1.In Figure 2 we marked in F1 the waterline of the boat when the nacelle is retracted inside the hull, and the line F2 waterline when the nacelle is in the extended position. Note that, in this case, the line F2 is always at a level lower than the end level of the nacelle 14. Under these conditions, the upwelling inside the nacelle is impossible. The variation in the waterline of the retracted nacelle and outgoing nacelle illustrates the advantage of having ballasted the hull 1.

A titre indicatif on indiquera qu'une embarcation telle que celle représentée peut avoir une longueur de 6 700 mm, une largeur de 2 500 mm, une hauteur nacelle rentrée d'environ 2 m, la nacelle pouvant plonger de 1 m sous le fond de la coque. Une telle embarcation peut facilement être transportée par route à l'instar des embar­cations traditionnelles.As an indication, it will be indicated that a boat such as that shown may have a length of 6,700 mm, a width of 2,500 mm, a retracted basket height of approximately 2 m, the basket being able to dive 1 m below the bottom of shell. Such a boat can easily be transported by road like traditional boats.

L'espace intérieur de la nacelle peut être aménagé pour constituer de jour une salle à manger, et de nuit un espace de couchage pouvant abriter jusqu'à trois personnes.The interior space of the nacelle can be arranged to constitute a dining room during the day, and at night a sleeping space that can accommodate up to three people.

L'invention trouve une application intéressante dans le domaine de la navigation de plaisance.The invention finds an interesting application in the field of pleasure boating.

On notera enfin un détail de réalisation en regard de la figure 1 résidant dans la provision entre chaque hublot 19 d'un projecteur 28 orientable depuis l'intérieur de la cabine, manuellement, afin d'éclairer une zone sous-­marine particulière.Finally, a detail of construction will be noted with reference to FIG. 1 residing in the provision between each porthole 19 of a projector 28 which can be rotated from inside the cabin, manually, in order to illuminate a particular underwater area.
