The boat comprises an inflatable tube 1, a rigid hull 4, and connection means 7 making the aforementioned rigid hull integral with the aforementioned inflatable tube. These connection means comprise a slide assembly 8 running around the periphery of the inflatable tube 1 and two support zones 9, 10 between the inflatable tube 1 and the rigid hull 4, these two support zones 9, 10 extending parallel on either side of the slide assembly 8, the relative arrangement between the aforementioned slide assembly 8 and the two aforementioned support zones 9, 10 being such that, when the inflatable tube 1 is inflated, the pressure exerted on the support zones 9, 10 causes a transverse tensile force in the engaged elements 8a, 8b of the slide assembly 8.

Description

Perfectionnements apportés aux embarcations pneumatiques à fond rigide.Improvements made to inflatable boats with rigid bottom.

L'invention est relative aux embarcations pneumatiques à fond rigide comportant un boudin gonflable constituant les côtés et la proue de l'embarcation, et un fond rigide constituant le plancher et la quille de l'embarcation, ces deux éléments constitutifs étant reliés l'un à l'autre par des moyens de liaison permettant le montage ou éventuellement le démontage de l'embarcation par son utilisateur. The invention relates to inflatable boats with rigid bottom comprising an inflatable tube constituting the sides and the bow of the boat, and a rigid bottom constituting the floor and the keel of the boat, these two constituent elements being connected one to the other by connecting means allowing the assembly or possibly disassembly of the boat by its user.

Le fait que ces moyens de liaison permettent au moins le montage de l'embarcation par son utilisateur permet de faciliter le stockage et l'expédition des embarcations dont les fonds rigides peuvent être empilés,et les boudins dégonflés mis en sacs. De plus, il est possible à l'utilisateur de changer lui-même le boudin gonflable en cas de détérioration de celui-ci, donc sans immobilisation à l'usine et à la station-service de l'embarcation. The fact that these connecting means allow at least the assembly of the boat by its user makes it possible to facilitate the storage and shipping of boats whose rigid bottoms can be stacked, and the deflated tubes placed in bags. In addition, it is possible for the user to change the inflatable tube himself in the event of deterioration thereof, therefore without immobilization at the factory and at the service station of the boat.

Cependant, la réalisation de ces moyens de liaison pose des problèmes car les conditions suivantes doivent, dans toute la mesure du possible, être obtenues - étanchéité entre le boudin gonflable et le fond rigide, - absence de toute saillie sur les parties extérieures du
boudin, saillies qui seraient nuisibles aux qualités
hydrodynamiques de l'embarcation, - absence de toute saillie sur les parties intérieures du
boudin, saillies qui seraient nuisibles au confort des
passagers, - obtention d'une finition la plus soignée possible, - facilité de montage et de démontage.However, the production of these connecting means poses problems because the following conditions must, as far as possible, be obtained - tightness between the inflatable tube and the rigid bottom, - absence of any projection on the external parts of the
sausage, projections which would be harmful to the qualities
hydrodynamics of the boat, - absence of any projection on the interior parts of the
sausage, projections which would be harmful to the comfort of
passengers, - obtaining the most careful finish possible, - ease of assembly and disassembly.

Or, jusqu'à ce jour, aucune des solutions proposées pour la réalisation des moyens de liaison entre le boudin gonflable et la coque rigide n'était satisfaisante, car les conditions évoquées ci-dessus n'étaient pas simultanément réunies.  However, to date, none of the solutions proposed for producing the connection means between the inflatable tube and the rigid shell have been satisfactory, since the conditions mentioned above were not simultaneously met.

L'invention a précisément pour but une embarcation pneumatique à fond rigide dans laquelle les moyens de liaison entre le boudin gonflable et le fond sont étanches, sont exempts de toute saillie extérieure et intérieure, permettent d'obtenir une finition soignée, et sont faciles à mettre en oeuvre pour le montage et le démontage. The object of the invention is precisely a pneumatic boat with a rigid bottom in which the means of connection between the inflatable tube and the bottom are sealed, are free from any external and internal protrusion, make it possible to obtain a neat finish, and are easy to use for assembly and disassembly.

Selon l'invention, l'embarcation comporte un boudin gonflable constituant les côtés et la proue de l'embarcation, un fond rigide constituant le plancher et la quille de l'embarcation, et des moyens de liaison permettant de solidariser, de préférence de façon démontable, le susdit fond rigide au susdit boudin gonflable, et elle est caractérisée par le fait que ces moyens de liaison comportent un assemblage à glissière régnant sur la périphérie du boudin gonflable et deux zones d'appui entre le boudin gonflable et le fond rigide, ces deux zones d'appui s'étendant parallèlement et de part et d'autre de l'assemblage à glissière, la disposition relative entre le susdit assemblage à glissière et les deux susdites zones d'appui étant telle que, lorsque le boudin gonflable est gonflé, la pression exercée sur les zones d'appui provoque un effort de traction transversal dans les éléments engagés de l'assemblage à glissière. According to the invention, the boat comprises an inflatable tube constituting the sides and the bow of the boat, a rigid bottom constituting the floor and the keel of the boat, and connecting means making it possible to secure, preferably so removable, the aforesaid rigid bottom to the aforesaid inflatable tube, and it is characterized by the fact that these connecting means comprise a slide assembly prevailing on the periphery of the inflatable tube and two bearing zones between the inflatable tube and the rigid base, these two support zones extending parallel and on either side of the slide assembly, the relative arrangement between the aforesaid slide assembly and the two aforementioned support zones being such that, when the inflatable tube is inflated, the pressure exerted on the bearing zones causes a transverse tensile force in the engaged elements of the slide assembly.

Grâce à cette disposition, on constate les avantages suivants - on obtient une étanchéité totale entre le boudin gonflable et le fond rigide au niveau des deux zones d'appui, - on réalise une jonction entre le fond rigide et le boudin gonflable exempte de toute saillie et présentant une finition soignée, et ce aussi bien du côté extérieur du boudin que du côté intérieur du boudin, les formes du fond rigide au niveau des deux zones d'appui-pouvant se raccorder de façon continue au boudin gonflable, - on permet un montage et eventuellement un démontage faciles étant donné que l'engagement des éléments de l'assemblage à glissière est effectué avant le gonflage du boudin gonflable et qu'il n'y a pas frottement des parties en regard du boudin gonflable et du fond rigide. Thanks to this arrangement, the following advantages are noted - a total seal is obtained between the inflatable tube and the rigid bottom at the level of the two support zones, - a junction is made between the rigid base and the inflatable tube free of any protrusion and having a neat finish, both on the outside of the tube and on the inside of the tube, the shapes of the rigid bottom at the two support zones - which can be connected continuously to the inflatable tube, - a easy assembly and possibly disassembly since the engagement of the elements of the slide assembly is carried out before the inflation of the inflatable tube and there is no friction of the parts opposite the inflatable tube and the rigid bottom.

L'invention consiste, mise à part la disposition dont il vient d'être question, en certaines autres dispositions qui s'utilisent de préférence en même temps et dont il sera plus explicitement question ciaprès. The invention consists, apart from the arrangement which has just been mentioned, in certain other arrangements which are preferably used at the same time and which will be more explicitly discussed below.

L'invention pourra, de toute façon, être bien comprise à l'aide du complément de description qui suit ainsi que du dessin ci-annexé, lesquels complément et dessin sont relatifs à un mode de réalisation préféré de l'invention et ne comportent, bien entendu, aucun caractère limitatif. The invention may, in any case, be well understood with the aid of the additional description which follows as well as of the appended drawing, which supplement and drawing relate to a preferred embodiment of the invention and do not include, of course, no limiting character.

La figure unique, de ce dessin, est une coupe transversale d'une embarcation pneumatique à fond rigide établie conformément à l'invention. The single figure of this drawing is a cross section of a rigid-bottomed inflatable boat constructed in accordance with the invention.

L'embarcation comporte un boudin gonflable 1 en forme de U ou de V constituant les côtés 2 et 3 et la proue (non visible sur la figure) de l'embarcation et un fond rigide 4 constituant le plancher 5 et la quille 6 de l'embarcation. The boat comprises an inflatable tube 1 in the shape of a U or V constituting the sides 2 and 3 and the bow (not visible in the figure) of the boat and a rigid bottom 4 constituting the floor 5 and the keel 6 of the 'boat.

Des moyens de liaison 7 permettent de solidariser de façon démontable le fond rigide 4 au boudin gonflable 1. Connection means 7 allow the rigid bottom 4 to be fixed in a removable manner to the inflatable tube 1.

Un tableau arrière (non visible sur la figure) est rendu solidaire de façon appropriée du fond rigide et/ou du boudin gonflable, ce tableau arrière constituant la poupe de l'embarcation et étant généralement destiné à recevoir un ou plusieurs moteurs hors-bord
Les moyens de liaison 7 comportent, - un assemblage à glissière 8 dont l'un des deux éléments, par exemple l'élément mâle 8a, est porté par le boudin gonflable 1, alors que l'autre élément, l'élément femelle 8b, est porté par le fond rigide 4, cet assemblage à glissière 8 régnant sur la périphérie du boudin gonflable 1, c'est-à-dire sur sa partie formant les deux côtés 2 et 3 de l'embarcation et sur sa partie formant la proue de l'embarcation, - et deux zones d'appui 9 et 10 entre le boudin gonflable 1 et le fond rigide 4, ces deux zones d'appui 9 etlO s'détendant parallèlement et de part et d'autre de l'assemblage à glissière 8.A transom (not visible in the figure) is suitably secured to the rigid bottom and / or the inflatable tube, this transom constituting the stern of the boat and generally being intended to receive one or more outboard motors
The connecting means 7 comprise, - a slide assembly 8, one of the two elements of which, for example the male element 8a, is carried by the inflatable tube 1, while the other element, the female element 8b, is carried by the rigid bottom 4, this slide assembly 8 prevailing on the periphery of the inflatable tube 1, that is to say on its part forming the two sides 2 and 3 of the boat and on its part forming the bow of the boat, - and two support zones 9 and 10 between the inflatable tube 1 and the rigid bottom 4, these two support zones 9 etlO extending parallel and on either side of the assembly to slide 8.

La disposition relative entre l'assemblage à glis sière 8 et les deux zones d'appui 9 et 10 est telle que, lorsque le boudin gonflable-l est gonflé, la pression exercée sur les zones d'appui 9 et 10 provoque un effort de traction transversal T dans les éléments engagés 8a, 8b de l'assemblage à glissière 8. The relative arrangement between the slide assembly 8 and the two support zones 9 and 10 is such that, when the inflatable tube-1 is inflated, the pressure exerted on the support zones 9 and 10 causes an effort of transverse traction T in the engaged elements 8a, 8b of the slide assembly 8.

Le montage d'une telle embarcation s' opère alors comme suit : on engage l'un dans l'autre les éléments 8a, 8b de l'assemblage à glissière 8 jusqu'à ce que le boudin gonflable 1 soit mis en place correctement sur le fond rigide 4, cette opération s'effectuant lorsque le boudin gonflable 1 n1 est pas, ou peu gonflé ; on procède ensuite au gonflage du boudin gonflable 1 à sa pression d'utilisation ; l'embarcation est alors en état de marche. The assembly of such a boat then takes place as follows: the elements 8a, 8b of the slide assembly 8 are engaged one in the other until the inflatable tube 1 is correctly positioned on the rigid bottom 4, this operation being carried out when the inflatable tube 1 is not, or only slightly inflated; the inflatable tube 1 is then inflated to its operating pressure; the boat is then in working order.

Pour le démontage, on procède au dégonflage total ou partiel du boudin gonflable 1 ; ensuite on désengage les éléments 8a, 8b de l'assemblage à glissière 8 jusqu 'à obtenir la séparation complète du boudin gonflable 1 du fond rigide 4. For disassembly, complete or partial deflation of the inflatable tube 1; then the elements 8a, 8b of the slide assembly 8 are disengaged until the complete separation of the inflatable tube 1 from the rigid base 4 is obtained.

Lorsque l'embarcation est neuve, il n'y a bien silr aucun problème pour l'engagement l'un dans l'autre des éléments 8a, 8b de l'assemblage à glissière 8. When the boat is new, there is of course no problem for the engagement of the elements 8a, 8b of the slide assembly 8 in one another.

Lorsque l'embarcation est restée à l'eau, il est à remarquer que l'assemblage à glissière 8 étant entouré par les deux zones d'appui 9 et 10, il ne s'y dépose aucun coquillage, ni aucune concrétion, et que le désengagement, puis l'engagement ultérieur des éléments 8a, 8b de l'assemblage à glissière, restent aussi faciles. When the boat has remained in the water, it should be noted that the slide assembly 8 being surrounded by the two support zones 9 and 10, there is no shell, or any concretion, and that disengagement, then subsequent engagement of elements 8a, 8b of the slide assembly, also remain easy.
