Description

La présente invention concerne un bateau comprenant un fond souple et bordé radialement vers l'extérieur par une paroi qui comprend une paroi avant gonflable et pliable, une paroi latérale gonflable et pliable, et une paroi arrière.The present invention relates to a boat comprising a flexible bottom and bordered radially towards the outside by a wall which comprises an inflatable and collapsible front wall, an inflatable and collapsible side wall, and a rear wall.

De tels bateaux présentent l'avantage, par rapport à un bateau de même taille à coque rigide ou semi-rigide comme divulgué par le document EP2593353 A , d'être significativement plus légers, et d'occuper un faible volume lorsqu'ils ne sont pas utilisés. En effet, les parois avant et latérale sont gonflables et pliables, formant chacune un boudin de section circulaire rempli d'air, et le plancher est déformable de telle sorte que le bateau entier peut être dégonflé et replié, à l'exception éventuellement de la paroi arrière. En effet, la paroi arrière est en général un panneau constituée d'un matériau (par exemple le bois) plus rigide que le matériau des boudins des parois avant et latérales car la paroi arrière est destinée à supporter le moteur du bateau. On qualifie un tel bateau de « bateau gonflable ».Such boats have the advantage, compared to a boat of the same size with a rigid or semi-rigid hull as disclosed by the document EP2593353A , to be significantly lighter, and to take up little space when not in use. Indeed, the front and side walls are inflatable and foldable, each forming a ring of circular section filled with air, and the floor is deformable so that the entire boat can be deflated and folded, with the possible exception of the rear wall. Indeed, the rear wall is generally a panel made of a material (for example wood) more rigid than the material of the flanges of the front and side walls because the rear wall is intended to support the engine of the boat. Such a boat is called an “inflatable boat”.

Dans la description qui suit, les termes « internes »/ « intérieur » et « externe » / « extérieur » sont définis par rapport au centre géométrique du bateau une fois gonflé.In the following description, the terms "internal"/"interior" and "external"/"exterior" are defined with respect to the geometric center of the boat once inflated.

Les termes « inférieur » / « supérieur » sont définis par rapport à l'axe vertical, qui est perpendiculaire au fond du bateau qui s'étend dans un plan horizontal en utilisation normale du bateau.The terms "lower" / "upper" are defined with respect to the vertical axis, which is perpendicular to the bottom of the boat which extends in a horizontal plane in normal use of the boat.

Le fond du bateau est constitué d'une toile pliable dont les bords latéraux sont fixés à la face inférieure des boudins (et à la paroi arrière) de telle sorte que ces boudins forment les parois avant et latérales du bateau.The bottom of the boat is made of a foldable canvas whose side edges are fixed to the underside of the socks (and to the rear wall) in such a way that these socks form the front and side walls of the boat.

Ainsi, les boudins des parois avant et latérales ayant une forme cylindrique de section circulaire, la moitié radialement interne des boudins se situe nécessairement au-dessus du plancher du bateau.Thus, the flanges of the front and side walls having a cylindrical shape of circular section, the radially inner half of the flanges is necessarily located above the floor of the boat.

En conséquence, l'espace intérieur du bateau est diminué de la moitié du volume des boudins, tout le long des parois avant et latérale du bateau. La surface utile et habitable du bateau s'en trouve réduite d'autant, ce qui est préjudiciable.Consequently, the interior space of the boat is reduced by half the volume of the tubes, all along the front and side walls of the boat. The useful and habitable surface of the boat is reduced accordingly, which is detrimental.

La présente invention vise à remédier à ces inconvénients.The present invention aims to remedy these drawbacks.

L'invention vise à proposer un bateau gonflable dont l'espace intérieur soit maximisé, les propriétés fonctionnelles et opérationnelles du bateau restant les mêmes que celles d'un bateau gonflable selon l'art antérieur.The invention aims to provide an inflatable boat whose interior space is maximized, the functional and operational properties of the boat remaining the same as those of an inflatable boat according to the prior art.

Ce but est atteint grâce au fait qu'au moins une partie d'une au moins de la paroi latérale et de la paroi avant est constituée par un premier élément gonflable conformé en plaque présentant deux faces planes parallèles, un second élément gonflable dont la section est en forme de D avec une portion plane, et un dispositif d'assemblage souple, le second élément étant situé radialement vers l'extérieur du bateau par rapport au premier élément, le dispositif d'assemblage maintenant la portion plane du second élément en contact avec une des faces du premier élément.This object is achieved thanks to the fact that at least a part of at least one of the side wall and of the front wall is constituted by a first inflatable element shaped as a plate having two flat parallel faces, a second inflatable element whose section is D-shaped with a flat portion, and a flexible assembly device, the second element being located radially towards the outside of the boat with respect to the first element, the assembly device maintaining the flat portion of the second element in contact with one of the faces of the first element.

Grâce à ces dispositions, l'espace disponible pour les passagers du bateau est optimisé. La stabilité du bateau n'est cependant pas compromise, car les parois présentent une forme extérieure sensiblement circulaire, le bateau conservant les mêmes dimensions qu'un bateau similaire de l'art antérieur. Le bateau conserve également son caractère entièrement gonflable (à l'exception éventuellement de la paroi arrière) et pliable.Thanks to these provisions, the space available for the passengers of the boat is optimized. The stability of the boat is not compromised, however, because the walls have a substantially circular outer shape, the boat retaining the same dimensions as a similar boat of the prior art. The boat also retains its fully inflatable (with the possible exception of the rear wall) and foldable character.

Avantageusement, le dispositif d'assemblage est choisi parmi un système d'accrochage, une gaine souple entourant au moins partiellement le premier élément et le second élément, et une combinaison des deux.Advantageously, the assembly device is chosen from among a hooking system, a flexible sheath at least partially surrounding the first element and the second element, and a combination of the two.

Ainsi, le poids du dispositif pour maintenir en contact le premier élément et le second élément est minimisé.Thus, the weight of the device for keeping the first element and the second element in contact is minimized.

Par exemple, le premier élément est situé en dehors du second élément.For example, the first element is located outside the second element.

Avantageusement, le second élément se prolonge en dessous du fond du bateau.Advantageously, the second element extends below the bottom of the boat.

Ainsi, la stabilité et la gouvernabilité du bateau est améliorée.Thus, the stability and the governability of the boat is improved.

Par exemple, le premier élément est situé dans le second élément.For example, the first element is located within the second element.

Avantageusement, lorsqu'une partie seulement de la paroi latérale et de la paroi avant comprend le premier élément et le second élément, la paroi comprend en outre une transition progressive qui relie cette partie avec le reste de la paroi.Advantageously, when only part of the side wall and of the front wall comprises the first element and the second element, the wall also comprises a progressive transition which connects this part with the rest of the wall.

Ainsi, on évite une transition abrupte dans la paroi du bateau, ce qui contribue à améliorer sa résistance.Thus, an abrupt transition in the wall of the boat is avoided, which contributes to improving its resistance.

Par exemple, la totalité de la paroi latérale comprend le premier élément et le second élément, et la transition relie la paroi latérale et la paroi avant.For example, the entire side wall includes the first element and the second element, and the transition connects the side wall and the front wall.

Avantageusement, la totalité de la paroi latérale et de la paroi avant comprend le premier élément et le second élément.Advantageously, the whole of the side wall and of the front wall comprises the first element and the second element.

Ainsi, l'espace disponible pour les passagers dans le bateau est maximisé.Thus, the space available for passengers in the boat is maximized.

Avantageusement, la paroi avant, le second élément, et le cas échéant la transition, délimitent un volume unique, apte à être gonflé à partir d'un seul point.Advantageously, the front wall, the second element, and if necessary the transition, delimit a single volume, capable of being inflated from a single point.

Ainsi, le bateau peut être déplié et gonflé dans sa position d'utilisation plus rapidement.Thus, the boat can be unfolded and inflated in its position of use more quickly.

Avantageusement, le fond comprend une toile sur laquelle est apte à être posé un plancher rigide amovible.Advantageously, the bottom comprises a canvas on which a removable rigid floor can be placed.

Le caractère amovible du plancher permet de conserver au bateau son caractère gonflable et pliable, tout en offrant un soutien plus rigide aux passagers.The removable nature of the floor allows the boat to retain its inflatable and foldable character, while offering more rigid support to the passengers.

L'invention sera bien comprise et ses avantages apparaîtront mieux, à la lecture de la description détaillée qui suit, d'un mode de réalisation représenté à titre d'exemple non limitatif. La description se réfère aux dessins annexés sur lesquels :

The boat comprises a flexible bottom 10, and a wall 20 which borders the bottom 10 radially outward.

Par élément « souple », on entend un élément dont une des trois dimensions est suffisamment petite devant les deux autres, et dont la rigidité du matériau le constituant est suffisamment faible, pour être pliable avec les mains.By “flexible” element, we mean an element of which one of the three dimensions is sufficiently small compared to the other two, and of which the rigidity of the material constituting it is sufficiently low, to be foldable with the hands.

Par élément « gonflable », on entend un élément constitué d'une enveloppe souple délimitant un volume et présentant un orifice obturable permettant le gonflage de l'élément par injection d'air dans ce volume.By “inflatable” element is meant an element consisting of a flexible envelope delimiting a volume and having a closable orifice allowing the element to be inflated by injecting air into this volume.

Le fond 10 est par exemple constitué d'une toile 11 souple.The bottom 10 is for example made of a flexible fabric 11.

Avantageusement, ce fond 10 est apte à recevoir un plancher 12 amovible, posé sur cette toile 11, et qui recouvre toute la surface du fond 10. L'addition du plancher 12 permet de rigidifier le fond 10.Advantageously, this bottom 10 is capable of receiving a removable floor 12, placed on this canvas 11, and which covers the entire surface of the bottom 10. The addition of the floor 12 makes it possible to stiffen the bottom 10.

Le plancher 12 est par exemple une plaque gonflable (similaire à l'élément 30 décrit ci-dessous). Le plancher 12 est ainsi uniquement constitué d'un matériau souple, ce qui permet son pliage.The floor 12 is for example an inflatable plate (similar to the element 30 described below). The floor 12 is thus made solely of a flexible material, which allows it to be folded.

Alternativement, le plancher 12 est une plaque rigide, soit d'un seul tenant, soit constituée de planches articulées en elles.Alternatively, the floor 12 is a rigid plate, either in one piece, or made up of boards hinged into them.

En option, le fond 10 comporte en outre une quille 13, rigide ou gonflable. La stabilité du bateau est ainsi améliorée.As an option, the bottom 10 further comprises a keel 13, rigid or inflatable. The stability of the boat is thus improved.

Par exemple, la quille 13 est constituée d'un ensemble de planches gonflables ou rigides.For example, the keel 13 consists of a set of inflatable or rigid boards.

Alternativement, la quille 13 est constituée d'un boudin gonflable de section circulaire qui est disposé entre la toile 11 et le plancher 12, ce qui permet de tendre la toile 11 pour lui conférer la forme d'une carène en V.Alternatively, the keel 13 consists of an inflatable tube of circular section which is placed between the canvas 11 and the floor 12, which makes it possible to stretch the canvas 11 to give it the shape of a V-shaped hull.

La figure 6 montre en perspective une portion longitudinale d'un tel fond 10 du bateau avec un plancher rigide 12 et une quille 13, et leurs positions par rapport aux parois latérales 22 (paroi bâbord 22b et paroi tribord 22t) représentées en pointillés, et décrites ci-dessous.There figure 6 shows in perspective a longitudinal portion of such a bottom 10 of the boat with a rigid floor 12 and a keel 13, and their positions relative to the side walls 22 (port wall 22b and starboard wall 22t) shown in dotted lines, and described below below.

La paroi 20 comporte une paroi avant 21 gonflable et une paroi latérale 22 gonflable. La paroi avant 21 est constituée de la partie de la paroi 20 qui forme la proue du bateau. La paroi latérale 22 est constituée de la partie de la paroi 20 qui forme les bords latéraux du bateau. Ainsi, la paroi latérale 22 est constituée d'une paroi bâbord 22b et d'une paroi tribord 22t, qui s'étendent sensiblement parallèlement l'une par rapport à l'autre depuis la paroi avant 21 jusqu'à l'arrière du bateau (jusqu'à la paroi arrière 23). Ces deux parois latérales (bâbord 22b et tribord 22t) étant symétriques par rapport à l'axe longitudinal central du bateau, la description ci-dessous de la paroi bâbord 22b s'applique également à la paroi tribord 22t.The wall 20 comprises an inflatable front wall 21 and an inflatable side wall 22. The front wall 21 consists of the part of the wall 20 which forms the bow of the boat. The side wall 22 consists of the part of the wall 20 which forms the side edges of the boat. Thus, the side wall 22 consists of a port wall 22b and a starboard wall 22t, which extend substantially parallel to each other from the front wall 21 to the rear of the boat. (up to the rear wall 23). These two side walls (22b port and 22t starboard) being symmetrical with respect to the central longitudinal axis of the boat, the description below of the port wall 22b also applies to the starboard wall 22t.

La périphérie du fond 10 du bateau, constituée par les bords du fond 10, est fixée à la paroi avant 21, à la paroi latérale 22, et à la paroi arrière 23. Cette fixation s'effectue au niveau de la partie inférieure de ces parois, comme visible sur les figures. La paroi latérale 22 est également fixée à la paroi arrière 23.The periphery of the bottom 10 of the boat, consisting of the edges of the bottom 10, is fixed to the front wall 21, to the side wall 22, and to the rear wall 23. This fixing takes place at the level of the lower part of these walls, as seen in the figures. Side wall 22 is also attached to rear wall 23.

On décrit tout d'abord un premier mode de réalisation, en référence à la figure 1 et à la figure 3.We first describe a first embodiment, with reference to the figure 1 and at the picture 3 .

La paroi avant 21 est formée d'un boudin de section cylindrique circulaire.The front wall 21 is formed of a bead of circular cylindrical section.

La périphérie du fond 10 est fixée à l'extrémité inférieure du diamètre vertical de ce boudin.The periphery of the bottom 10 is fixed to the lower end of the vertical diameter of this bead.

La paroi bâbord 22b comprend un premier élément 30 gonflable conformé en plaque présentant deux faces planes parallèles, ces faces parallèles étant une face plane interne 31 et une face plane externe 32.The port side wall 22b comprises a first inflatable element 30 shaped as a plate having two flat parallel faces, these parallel faces being an internal flat face 31 and an external flat face 32.

Le premier élément 30 est conformé en plaque grâce à des liaisons souples (fils ou fibres ou rubans) qui relient la face interne 31 et la face externe 32 de telle sorte que la distance entre ces faces est sensiblement constante sur toute la surface du premier élément 30. Ces liaisons 33 sont fixées (par exemple par collage ou couture) à la face interne 31 et à la face externe 32. Ces liaisons 33 sont visibles sur la figure 3.The first element 30 is shaped as a plate thanks to flexible connections (wires or fibers or tapes) which connect the internal face 31 and the external face 32 in such a way that the distance between these faces is substantially constant over the entire surface of the first element. 30. These links 33 are fixed (for example by gluing or sewing) to the internal face 31 and to the external face 32. These links 33 are visible on the picture 3 .

La paroi bâbord 22b comprend en outre un second élément 40 gonflable dont la section est en forme de D et qui est situé radialement vers l'extérieur par rapport au premier élément 30. La portion plane 41 du second élément 40 est la partie rectiligne du « D », et est en contact (direct, ou indirect par le système d'accrochage 70, voir ci-dessous) avec la face externe 32 du premier élément 30. Le premier élément 30 est ainsi situé en dehors du second élément 40.The port side wall 22b further comprises a second inflatable element 40 whose section is D-shaped and which is located radially outward relative to the first element 30. The flat portion 41 of the second element 40 is the rectilinear part of the "D", and is in contact (direct, or indirect by the attachment system 70, see below) with the outer face 32 of the first element 30. The first element 30 is thus located outside the second element 40.

Ce contact entre le premier élément 30 et le second élément 40 est réalisé exclusivement par un dispositif d'assemblage souple, ce qui permet de conserver à la paroi 20 sont caractère souple et pliable (à l'exception éventuellement de la paroi arrière 23).This contact between the first element 30 and the second element 40 is made exclusively by a flexible assembly device, which allows the wall 20 to retain its flexible and bendable character (with the possible exception of the rear wall 23).

Par exemple, ce contact est réalisé par accroche de la portion plane 41 du second élément 40 sur la face externe 32 du premier élément 30, à l'aide d'un système d'accrochage (par exemple constitué d'un adhésif et/ou d'un laçage, et/ou d'un velcro) 70 qui constitue donc le dispositif d'assemblage.For example, this contact is made by attaching the flat portion 41 of the second element 40 to the outer face 32 of the first element 30, using an attachment system (for example consisting of an adhesive and/or a lacing, and / or a Velcro) 70 which therefore constitutes the assembly device.

Alternativement, ou en supplément, ce contact est réalisé à l'aide d'une gaine souple 60 dans laquelle se logent le premier élément 30 et le second élément 40. Avantageusement, la gaine 60 contribue à conformer le premier élément 30 dans sa forme plane et le second élément 40 dans sa forme en D. Par exemple, la gaine 60, qui est fixée au second élément 40 par le système d'accrochage 70, forme une alvéole tubulaire dans lequel le premier élément 30 peut être inséré (glissé) de telle sorte que la gaine 60 entoure complètement le premier élément 30, à l'exception de ses extrémités. Ce mode de réalisation présente l'avantage que le premier élément 30 peut être enlevé de la gaine 60 pour réparation puis introduit à nouveau dans la gaine 60 pour être assemblé avec le second élément 40 par l'intermédiaire de la gaine 60. En option, la gaine 60 forme une autre alvéole tubulaire conformée pour recevoir le second élément 40 sans qu'un système d'accrochage 70 de la gaine 60 sur le second élément 40 soit nécessaire.Alternatively, or in addition, this contact is made using a flexible sheath 60 in which the first element 30 and the second element 40 are housed. and the second element 40 in its D-shape. For example, the sheath 60, which is fixed to the second element 40 by the attachment system 70, forms a tubular cell in which the first element 30 can be inserted (slid) from such that the sheath 60 completely surrounds the first element 30, with the exception of its ends. This embodiment has the advantage that the first element 30 can be removed from the sheath 60 for repair and then introduced again into the sheath 60 to be assembled with the second element 40 via the sheath 60. As an option, the sheath 60 forms another tubular cell shaped to receive the second element 40 without a hooking system 70 of the sheath 60 on the second element 40 being necessary.

D'autres combinaisons que celles décrites ci-dessus sont possible, et dans le cas général, la gaine souple 60 et/ou le système d'accrochage 70 constituent le dispositif d'assemblage du premier élément 30 avec le second élément 40.Other combinations than those described above are possible, and in the general case, the flexible sheath 60 and/or the attachment system 70 constitute the device for assembling the first element 30 with the second element 40.

Comme représenté à titre d'exemple en figure 3, qui est une coupe transversale selon le plan A-A de la figure 1 de la paroi bâbord 22b de la paroi latérale 22, la gaine 60 est constituée d'une portion inférieure 61 qui recouvre les bords inférieurs du premier élément 30 et du second élément 40, et d'une portion supérieure 62 qui recouvre les bords supérieurs du premier élément 30 et du second élément 40. La portion inférieure 61 est fixée par le système d'accrochage 70 qui est ici un adhésif à la fois sur la partie inférieure du premier élément 30 et la partie inférieure du second élément 40, et la portion supérieure 62 est collée par l'adhésif 70 à la fois sur la partie supérieure du premier élément 30 et la partie supérieure du second élément 40 de telle sorte qu'après gonflage du premier élément 30 et du second élément 40, la portion plane 41 du second élément 40 est en contact avec la face externe 32 du premier élément 30. La portion inférieure 61 et la portion supérieure 62 sont disjointes. Alternativement elles se rejoignent en recouvrant la face incurvée du D de la paroi bâbord 22b, c'est-à-dire la face radialement externe de cette paroi.As shown by way of example in picture 3 , which is a cross-section along plane AA of the figure 1 of the port wall 22b of the side wall 22, the sheath 60 consists of a lower portion 61 which covers the lower edges of the first element 30 and of the second element 40, and of an upper portion 62 which covers the upper edges of the first element 30 and of the second element 40. The lower portion 61 is fixed by the attachment system 70 which here is an adhesive both on the lower part of the first element 30 and the lower part of the second element 40, and the upper portion 62 is glued by the adhesive 70 to both the upper part of the first element 30 and the upper part of the second element 40 so that after inflation of the first element 30 and of the second element 40 , the flat portion 41 of the second element 40 is in contact with the outer face 32 of the first element 30. The lower portion 61 and the upper portion 62 are separate. Alternatively they come together covering the curved face of the D of the port side wall 22b, that is to say the radially outer face of this wall.

En option, la portion plane 41 est collée avec la face externe 32 par l'adhésif 70, ce qui contribue à la solidité de la paroi bâbord 22b et à maintenir la portion plane 41 la plus plane possible.As an option, the flat portion 41 is glued with the external face 32 by the adhesive 70, which contributes to the solidity of the port side wall 22b and to keeping the flat portion 41 as flat as possible.

La périphérie du fond 10 est fixée à l'extrémité inférieure de la paroi bâbord 22b, par exemple à l'extrémité inférieure du premier élément 30, ou à la portion inférieure 61 de la gaine 60 dans le cas où cette gaine 60 est présente.The periphery of the bottom 10 is fixed to the lower end of the port side wall 22b, for example to the lower end of the first element 30, or to the lower portion 61 of the sheath 60 in the case where this sheath 60 is present.

La paroi 20 comporte une transition 25 progressive (visible sur la figure 1) qui relie la paroi latérale 22 et la paroi avant 21, cette transition 25 étant constituée d'une transition bâbord 25b qui relie la paroi bâbord 22b et la paroi avant 21, et d'une transition tribord 25t qui relie la paroi tribord 22t et la paroi avant 21.The wall 20 comprises a progressive transition 25 (visible on the figure 1 ) which connects the side wall 22 and the front wall 21, this transition 25 consisting of a port transition 25b which connects the port wall 22b and the front wall 21, and of a starboard transition 25t which connects the starboard wall 22t and the front wall 21.

La transition bâbord 25b (et par symétrie la transition tribord 25t) est constituée d'un cylindre avec une section transversale (c'est-à-dire dans un plan transversal à la direction du boudin de la paroi 20) évolutive depuis une section circulaire à l'endroit de la jonction de la transition bâbord 25b avec la paroi avant 21, jusqu'à une section en D à l'endroit de la jonction de la transition bâbord 25b avec le second élément 40. Cette évolution dans la forme de la paroi bâbord 25b se fait progressivement, ce qui évite les concentrations de contraintes dans la paroi 20, et contribue à la solidité du bateau.The port transition 25b (and by symmetry the starboard transition 25t) consists of a cylinder with a transverse section (that is to say in a plane transverse to the direction of the flange of the wall 20) evolving from a circular section at the location of the junction of the port transition 25b with the front wall 21, to a D section at the location of the junction of the port transition 25b with the second element 40. This evolution in the shape of the port side wall 25b is done gradually, which avoids stress concentrations in the wall 20, and contributes to the solidity of the boat.

D'une manière générale, lorsqu'une partie seulement de la paroi latérale 22 et de la paroi avant 21 comprend le premier élément 30 et le second élément 40, la paroi 20 comprend en outre la transition 25.In general, when only part of the side wall 22 and the front wall 21 comprises the first element 30 and the second element 40, the wall 20 further comprises the transition 25.

La paroi avant 21, la transition 25, et le second élément 40 délimitent un volume unique, apte à être gonflé à partir d'un seul point. Ainsi, le gonflage du bateau est plus pratique.The front wall 21, the transition 25, and the second element 40 delimit a single volume, capable of being inflated from a single point. Thus, the inflation of the boat is more convenient.

Alternativement, la paroi 20 du bateau est compartimentée en plusieurs sections disjointes et gonflables séparément, par exemple au niveau des jonctions entre la paroi avant 21, la transition 25, et le second élément 40. Ainsi, on évite que tout le bateau se dégonfle s'il est percé par accident en un seul endroit.Alternatively, the wall 20 of the boat is compartmentalized into several disjoint and separately inflatable sections, for example at the level of the junctions between the front wall 21, the transition 25, and the second element 40. This prevents the entire boat from deflating. is pierced by accident in one place.

Le premier élément 30 constitue un volume distinct du second élément 40, qui est gonflé séparément de ce dernier.The first element 30 constitutes a separate volume from the second element 40, which is inflated separately from the latter.

Alternativement, le volume du premier élément 30 communique avec le volume du second élément 40 à l'aide d'une valve de surpression.Alternatively, the volume of the first element 30 communicates with the volume of the second element 40 using a pressure relief valve.

Dans ce cas, la paroi avant 21, la paroi latérale 22, et le cas échéant la transition 25 délimitent un volume unique, apte à être gonflé à partir d'un seul point.In this case, the front wall 21, the side wall 22, and where applicable the transition 25 delimit a single volume, able to be inflated from a single point.

La pression de gonflage du premier élément 30 est supérieure à la pression de gonflage du second élément 40, par exemple 4 à 5 fois supérieure. Par exemple, la pression de gonflage du second élément 40 est de l'ordre de 200 à 250 mbar (millibars), et la pression de gonflage du premier élément 30 est de l'ordre de 1000 mbar.The inflation pressure of the first element 30 is higher than the inflation pressure of the second element 40, for example 4 to 5 times higher. For example, the inflation pressure of the second element 40 is of the order of 200 to 250 mbar (millibars), and the inflation pressure of the first element 30 is of the order of 1000 mbar.

Dans le mode de réalisation décrit ci-dessus, la transition 25 est entre la paroi avant 21 et la paroi latérale 22.In the embodiment described above, the transition 25 is between the front wall 21 and the side wall 22.

En variante, la transition 25 se situe à un lieu donné le long de la paroi avant 21.Alternatively, the transition 25 is located at a given location along the front wall 21.

En variante, la transition 25 se situe à un lieu donné le long de la paroi latérale 22.Alternatively, the transition 25 is located at a given location along the side wall 22.

La figure 2 illustre un autre mode de réalisation d'un bateau selon l'invention.There picture 2 illustrates another embodiment of a boat according to the invention.

La totalité de la paroi latérale 22 et de la paroi avant 21 comprend le premier élément 30 et le second élément 40. Ainsi, il n'y a pas de transition 25 dans la paroi 20, qui est formée uniquement du premier élément 30 et du second élément 40.The whole of the side wall 22 and the front wall 21 comprises the first element 30 and the second element 40. Thus, there is no transition 25 in the wall 20, which is formed only of the first element 30 and the second element 40.

Ce mode de réalisation présente l'avantage que les dimensions de l'habitacle du bateau sont maximisées.This embodiment has the advantage that the dimensions of the cabin of the boat are maximized.

La figure 4 illustre un autre mode de réalisation de la paroi d'un bateau selon l'invention, qui s'applique indifféremment au mode de réalisation du bateau de la figure 1 et de la figure 2. Le premier élément 30 est situé dans le second élément 40. La portion plane 41 du second élément 40 est alors en contact avec la face interne 31 du premier élément 30.There figure 4 illustrates another embodiment of the wall of a boat according to the invention, which applies equally to the embodiment of the boat of the figure 1 and some figure 2 . The first element 30 is located in the second element 40. The planar portion 41 of the second element 40 is then in contact with the internal face 31 of the first element 30.

Dans ce cas, une gaine 60 n'est pas nécessaire, la face interne 31 du premier élément 30 étant fixée par le système d'accrochage 70 sur la surface de la portion plane 41 du second élément 40 qui est située dans le volume de ce second élément 40. Ainsi, la solidité de la paroi bâbord 22b et à maintenir la portion plane 41 la plus plane possibleIn this case, a sheath 60 is not necessary, the internal face 31 of the first element 30 being fixed by the attachment system 70 on the surface of the flat portion 41 of the second element 40 which is located in the volume of this second element 40. Thus, the solidity of the port side wall 22b and to maintain the flat portion 41 as flat as possible

La périphérie du fond 10 est fixée à l'extrémité inférieure de la paroi bâbord 22b.The periphery of the bottom 10 is attached to the lower end of the port side wall 22b.

La figure 5 illustre encore un autre mode de réalisation de la paroi d'un bateau selon l'invention, qui est une variante du mode de réalisation de la figure 3, et qui s'applique indifféremment au mode de réalisation du bateau de la figure 1 et de la figure 2. La différence entre ces deux modes de réalisation est que le premier élément 30 se prolonge verticalement vers le bas en dessous du fond 10 du bateau.There figure 5 illustrates yet another embodiment of the wall of a boat according to the invention, which is a variant of the embodiment of the picture 3 , and which applies equally to the embodiment of the boat of the figure 1 and some figure 2 . The difference between these two embodiments is that the first element 30 extends vertically downwards below the bottom 10 of the boat.

Ainsi, la périphérie du fond 10 est fixée à l'extrémité inférieure du second élément 40 de la paroi bâbord 22b.Thus, the periphery of the bottom 10 is fixed to the lower end of the second element 40 of the port side wall 22b.

L'invention a été décrite ci-dessus dans le cas où le second élément 40 à bâbord et à tribord du bateau est un boudin de section transversale en D. Alternativement, le second élément 40 est constitué d'un ensemble de boudins 44, par exemple de section transversale circulaire, et de différentes largeurs (ou diamètres) de telle sorte que cet ensemble occupe un volume en forme de D. Les boudins de cet ensemble sont maintenus en contact au niveau de leurs lignes de contact directement par un moyen de fixation (par exemple par collage avec un adhésif ou par laçage, ou couture, ou par velcro), et/ou indirectement par une gaine 60.The invention has been described above in the case where the second element 40 on the port side and on the starboard side of the boat is a flange of cross-section in D. Alternatively, the second element 40 consists of a set of flanges 44, for example of circular cross-section, and of different widths (or diameters) so that this assembly occupies a D-shaped volume. The flanges of this assembly are held in contact at their lines of contact directly by a fastening means (for example by gluing with an adhesive or by lacing, or sewing, or by Velcro), and/or indirectly by a sheath 60.

Par exemple, ces boudins sont tous identiques.For example, these sausages are all identical.

Par exemple, ces boudins 44 sont de largeur plus petite en haut et en bas du D, et de largeur plus grande au milieu du D. Par exemple, comme représenté en figure 7, cet ensemble est constitué d'un boudin circulaire 441 de diamètre supérieur entouré de deux boudins 442 de diamètre inférieur, un au-dessus et un en dessous, cet ensemble de boudins étant maintenus en contact par une gaine 60 qui entoure l'ensemble de ces boudins sur toute leur longueur.For example, these flanges 44 are of smaller width at the top and bottom of the D, and of greater width in the middle of the D. For example, as shown in figure 7 , this assembly consists of a circular tube 441 of greater diameter surrounded by two tubes 442 of smaller diameter, one above and one below, this assembly of tubes being held in contact by a sheath 60 which surrounds the assembly of these sausages over their entire length.

Selon l'invention, le premier élément 30 et le second élément 40 constituent une partie d'une au moins de la paroi latérale 22 et de la paroi avant 21. Ainsi, le premier élément 30 et le second élément 40 constituent soit une partie (ou la totalité) de la paroi latérale 22, soit une partie (ou la totalité) de la paroi avant 21, soit une partie (ou la totalité) de la paroi latérale 22 et de la paroi avant 21.According to the invention, the first element 30 and the second element 40 constitute a part of at least one of the side wall 22 and of the wall front 21. Thus, the first element 30 and the second element 40 constitute either a part (or the whole) of the side wall 22, or a part (or the whole) of the front wall 21, or a part (or the whole ) of the side wall 22 and the front wall 21.
