Abstract

The inflatable vessel comprises an inflatable fender (1) with two parallel branches (2) joining up at the front to form a stem. A bottom canvas (5) forms a V shaped hull maintained by a longitudinal keel (6). The keel is interposed between a transverse rigid bottom (4), held along the two branches, and the bottom canvas which is connected to the fender along the bottom peripheral edges. Two auxiliary floats (7) extending under the bottom parallel to the branches are displaced towards the centre. The auxiliary floats have their lower edge (7a) located lower than the keel lower edge and the lower edge (2a) of each fender branch. Each float has an inflatable compartment and two skirts which extend longitudinally on each side of the compartment and are fixed under the bottom canvas.

Description

La présente invention concerne des perfectionnements apportés aux embarcations pneumatiques comportant au moins un boudin gonflable formant deux branches sensiblement parallèles se rejoignant vers l'avant pour former une étrave, une toile de fond formant une carène en V étant tendue par une quille longitudinale qui est interposée entre un fond rigide dans le sens transversal maintenu le long des deux susdites branches et ladite toile de fond qui se raccorde audit boudin le long des bords périphériques du fond, deux flotteurs auxiliaires s'étendant sous le fond sensiblement parallèlement auxdites branches respectives, en étant décalées vers le centre par rapport à celles-ci.The present invention relates to improvements made to inflatable boats comprising at least one inflatable tube forming two substantially parallel branches joining forward to form a bow, a backdrop forming a V-shaped hull being tensioned by a longitudinal keel which is interposed between a rigid bottom in the transverse direction maintained along the two aforementioned branches and said backdrop which is connected to said flange along the peripheral edges of the bottom, two auxiliary floats extending under the bottom substantially parallel to said respective branches, being offset to the center with respect to them.

Pour améliorer les caractéristiques de navigabilité aux grandes vitesses (confort, facilité de déjaugeage, tenue de cap,...) tout en conservant aux basses ou moyennes vitesses une immersion correcte de l'hélice, il a déjà été proposé (FR 2 398 660, FR 2 510 064) que, au moins dans leur partie sensiblement parallèle, chacune des deux branches du boudin présente, en section transversale, une forme plurilobée, notamment bilobée, dont le grand axe est incliné et dans laquelle le compartiment supérieur présente une section supérieure à celle du compartiment inférieur ; en outre, une toile latérale est fixée tangentiellement à certains au moins des lobes sur le côté extérieur de la branche considérée, notamment est fixée tangentiellement au grand lobe supérieur et au petit lobe inférieur de la structure bilobée, ces toiles latérales constituant des plans de sustentation latéraux sur lesquels s'exerce la portance.To improve the airworthiness characteristics at high speeds (comfort, easy planing, course keeping, etc.) while retaining correct immersion of the propeller at low or medium speeds, it has already been proposed (FR 2 398 660 , FR 2 510 064) that, at least in their substantially parallel part, each of the two branches of the tube has, in cross section, a multi-lobed shape, in particular bilobed, whose major axis is inclined and in which the upper compartment has a section higher than that of the lower compartment; in addition, a lateral fabric is fixed tangentially to at least some of the lobes on the external side of the branch in question, in particular is fixed tangentially to the large upper lobe and to the small lower lobe of the bilobed structure, these lateral fabrics constituting support planes lateral on which the lift is exerted.

Les embarcations de ce type donnent entièrement satisfaction et connaissent un très grand développement.Boats of this type are entirely satisfactory and are experiencing great development.

Toutefois la structure multilobée de chaque branche est complexe à fabriquer et donc coûteuse. De ce fait, cette structure perfectionnée est réservée jusqu'à présent aux embarcations de haut de gamme.However, the multi-lobed structure of each branch is complex to manufacture and therefore expensive. As a result, this improved structure has so far been reserved for high-end boats.

Mais il existe actuellement une demande pour des embarcations de gamme basse ou moyenne qui présenteraient les avantages de navigabilité précités tout en conservant un prix de fabrication moindre que celui qu'implique la mise en oeuvre d'une structure plurilobée telle que décrite plus haut.But there is currently a demand for low or medium range boats which would have the aforementioned airworthiness advantages while retaining a lower manufacturing price than that implied by the implementation of a multi-lobed structure as described above.

L'invention a donc essentiellement pour but de proposer une structure perfectionnée qui soit apte à procurer les avantages souhaités (notamment confort, facilité de déjaugeage, bonne tenue de cap) tout en étant simple et moins coûteuse à mettre en oeuvre à la fabrication, et qui permette donc la réalisation d'embarcations ayant les caractéristiques recherchées dans des gammes moyennes, voire même basses.The object of the invention is therefore essentially to provide an improved structure which is capable of providing the desired advantages (in particular comfort, ease of planing, good heading stability) while being simple and less costly to implement during manufacture, and which therefore allows the realization of boats with the desired characteristics in medium ranges, even low.

A ces fins, l'invention propose une embarcation gonflable du type indiqué au préambule qui, étant agencée conformément à l'invention, se caractérise essentiellement en ce que les deux flotteurs auxiliaires sont solidarisés à ladite toile de fond, sur le dessous de celle-ci. De préférence, lesdits flotteurs auxiliaires s'étendant à proximité des branches tout en étant physiquement distincts de celles-ci.For these purposes, the invention provides an inflatable boat of the type indicated in the preamble which, being arranged in accordance with the invention, is essentially characterized in that the two auxiliary floats are secured to said backdrop, on the underside thereof. this. Preferably, said auxiliary floats extending close to the branches while being physically distinct from them.

Une telle structure permet d'écarter les difficultés de réalisation des structures plurilobées utilisées jusqu'à présent. En effet, le boudin principal est conçu et fabriqué de la façon couramment mise en oeuvre pour les embarcations à structure gonflable simple, à un seul boudin gonflable, connues antérieurement aux embarcations à structure plurilobées. Quant aux flotteurs auxiliaires, ils peuvent donner lieu à des fabrications individuelles et être ensuite rapportés : de ce fait, non seulement leur fabrication peut être faite de façon simple et économique, mais leur fixation peut elle aussi être réalisée de façon simple et relativement peu coûteuse comme cela apparaîtra plus loin.Such a structure makes it possible to eliminate the difficulties of producing the multi-lobed structures used until now. Indeed, the main tube is designed and manufactured in the manner commonly used for boats with a simple inflatable structure, with a single inflatable tube, known before to boats with multi-lobed structure. As for the auxiliary floats, they can give rise to individual manufacturing and then be added: therefore, not only can they be manufactured in a simple and economical manner, but their fixing can also be carried out in a simple and relatively inexpensive manner. as will appear later.

Avantageusement, les deux flotteurs auxiliaires ont leur bord inférieur situé sensiblement plus bas que le bord inférieur de la quille. De même, il souhaitable que les deux flotteurs auxiliaires aient leur bord inférieur situé sensiblement plus bas que le bord inférieur de chaque branche du boudin.Advantageously, the two auxiliary floats have their lower edge situated substantially lower than the lower edge of the keel. Likewise, it is desirable that both auxiliary floats have their lower edge located substantially lower than the lower edge of each branch of the tube.

Pour sa fixation, chaque flotteur auxiliaire peut comprendre une enceinte gonflable et deux jupes, continues ou discontinues, s'étendant longitudinalement respectivement de chaque côté de l'enceinte et solidarisées sous la toile de fond.For its attachment, each auxiliary float may include an inflatable enclosure and two skirts, continuous or discontinuous, extending longitudinally respectively on each side of the enclosure and secured under the backdrop.

Toutefois, il semble plus rapide et plus simple de prévoir, selon un mode de réalisation préféré, que chaque flotteur auxiliaire comprenne une poche allongée longitudinalement et solidarisée sous la toile de fond et une enceinte gonflable réalisée sous forme d'un élément individuel indépendant de la poche et introduit dans ladite poche.However, it seems quicker and simpler to provide, according to a preferred embodiment, that each auxiliary float comprises a pocket elongated longitudinally and secured to the backdrop and an inflatable enclosure produced as an individual element independent of the pocket and inserted into said pocket.

De préférence, la quille est une quille pneumatique constituée par au moins une enceinte gonflable allongée.Preferably, the keel is a pneumatic keel constituted by at least one elongated inflatable enclosure.

Dans un mode de réalisation préféré, le bord de la paroi intérieure de chaque poche est plaqué et solidarisé sur la toile de fond en étant dirigé vers le bord le plus proche de celle-ci et, les enceintes des flotteurs auxiliaires et la quille étant gonflées, les deux flotteurs auxiliaires sont sensiblement plaqués contre le dessous du fond, la toile de fond formant, avec la quille, une carène centrale en V s'étendant transversalement entre les deux flotteurs auxiliaires et la paroi des poches des flotteurs auxiliaires qui est située latéralement vers l'extérieur s'étendant obliquement en faisant office de plan de sustentation latéral sur lequel s'exerce la portance.In a preferred embodiment, the edge of the inner wall of each pocket is pressed and secured to the backdrop, being directed towards the edge closest to it, and the enclosures of the auxiliary floats and the keel being inflated. , the two auxiliary floats are substantially pressed against the underside of the bottom, the backdrop forming, with the keel, a central V-shaped hull extending transversely between the two auxiliary floats and the wall of the pockets of the auxiliary floats which is located laterally outwards extending obliquely, acting as a lateral support plane on which the lift is exerted.

L'invention sera mieux comprise à la lecture de la description qui suit de certains modes de réalisation donnés uniquement à titre d'exemples nullement limitatifs. Dans cette description on se réfère aux dessins annexés sur lesquels :

  • la figure 1 est une vue simplifiée, en coupe transversale, d'un agencement de base d'une embarcation pneumatique conforme à l'invention,
  • les figures 2 et 3 sont des vues simplifiées, en coupe transversale, de respectivement deux autres modes de réalisation d'embarcation conformes à l'invention,

  • la figure 6 est une vue de dessous, en perspective, de l'embarcation de la figure 4.
The invention will be better understood on reading the following description of certain embodiments given solely by way of non-limiting examples. In this description, reference is made to the appended drawings in which:
  • FIG. 1 is a simplified view, in cross section, of a basic arrangement of an inflatable boat according to the invention,
  • FIGS. 2 and 3 are simplified views, in cross section, of respectively two other embodiments of a boat according to the invention,
  • FIG. 4 is a simplified view, in cross section, of a preferred embodiment of a boat according to the invention,
  • FIG. 5 is a simplified view in cross section, showing the arrangement of the backdrop and of its pockets, in the non-inflated state, used in the boat of FIG. 4, and
  • FIG. 6 is a bottom view, in perspective, of the boat of FIG. 4.

Comme visible sur la figure 1, l'embarcation comporte un boudin gonflable principal 1 formant deux branches 2 sensiblement parallèles qui se rejoignent vers l'avant pour former une étrave 3.As can be seen in FIG. 1, the boat comprises a main inflatable tube 1 forming two substantially parallel branches 2 which join forward to form a bow 3.

Un tableau arrière (non visible) relie les extrémités arrière des deux branches 2 et est destiné à recevoir au moins un moteur, notamment du type hors-bord (non représenté).A transom (not visible) connects the rear ends of the two branches 2 and is intended to receive at least one engine, in particular of the outboard type (not shown).

Le long des deux branches 2 de l'embarcation est maintenu un plancher ou fond 4 rigide dans le sens transversal. Ce fond peut être constitué par une juxtaposition de lattes ou plaques rigides solidarisées les unes aux autres de façon articulée, ou bien encore être constitué d'au moins une poche plate et plane gonflée sous relativement haute pression. Une toile de fond 5, située sous le fond 4, se raccorde aux bords périphériques du fond 4, le long de la liaison de celui-ci au boudin 1. Entre le fond 4 et la toile de fond 5 est interposée une quille 6 qui tend la toile de fond 5 pour lui conférer la forme d'une carène en V. De préférence la quille 6 est une quille pneumatique constituée par au moins une enceinte gonflable allongée.Along the two branches 2 of the boat is maintained a rigid floor or bottom 4 in the transverse direction. This bottom may consist of a juxtaposition of slats or rigid plates joined to each other in an articulated manner, or alternatively be made of at least one flat and flat pocket inflated under relatively high pressure. A backdrop 5, located under the bottom 4, is connected to the peripheral edges of the bottom 4, along the connection of the latter to the tube 1. Between the bottom 4 and the backdrop 5 is interposed a keel 6 which stretches the backdrop 5 to give it the shape of a V-shaped hull. Preferably the keel 6 is a pneumatic keel formed by at least one elongated inflatable enclosure.

Enfin, décalés vers le centre par rapport aux branches 2 du boudin principal 1, deux flotteurs auxiliaires 7 sont situés sur la face externe ou dessous de la toile de fond 5 et s'étendent sensiblement parallèlement auxdites branches 2, à proximité de celles-ci tout en en étant physiquement distincts. Les deux flotteurs auxiliaires 7 sont configurés de manière que leur bord inférieur 7a soit situé sensiblement plus bas que le bord inférieur 6a de la quille, et éventuellement aussi plus bas que le bord inférieur 2a des branches 2, en fonction des caractéristiques de navigabilité que l'on souhaite conférer à l'embarcation.Finally, offset towards the center with respect to the branches 2 of the main rod 1, two auxiliary floats 7 are located on the external face or below of the canvas bottom 5 and extend substantially parallel to said branches 2, close to the latter while being physically distinct therefrom. The two auxiliary floats 7 are configured so that their lower edge 7a is located substantially lower than the lower edge 6a of the keel, and possibly also lower than the lower edge 2a of the branches 2, according to the airworthiness characteristics that the '' we want to confer on the boat.

Pour assurer la fixation de chaque flotteur 7 sur la toile de fond 5, on peut prévoir que chaque flotteur 7 comprenne une enceinte gonflable allongée 8 et deux jupes 9 qui s'étendent longitudinalement de chaque côté de ladite enceinte 8 et qui sont solidarisées, par exemple par soudure, à la face externe de la toile de fond 5, comme représenté à la figure 2. Chaque jupe peut être discontinue, mais de préférence elle est continue de façon à éviter les turbulences des écoulements liquides sur ses faces.To ensure the attachment of each float 7 on the backdrop 5, provision can be made for each float 7 to comprise an elongated inflatable enclosure 8 and two skirts 9 which extend longitudinally on each side of said enclosure 8 and which are joined together by example by welding, to the external face of the backdrop 5, as shown in FIG. 2. Each skirt may be discontinuous, but preferably it is continuous so as to avoid turbulence of the liquid flows on its faces.

Dans un autre mode de réalisation représenté à la figure 3, chaque flotteur auxiliaire 7 comprend une poche allongée 10 fixée à la face externe de la toile de fond 5 et s'étendant sensiblement parallèlement à la branche adjacente respective 2 du boudin principal 1 ; une enceinte gonflable allongée 8, fabriquée individuellement sous forme d'un élément indépendant, est introduite dans ladite poche 10.In another embodiment shown in FIG. 3, each auxiliary float 7 comprises an elongated pocket 10 fixed to the external face of the backdrop 5 and extending substantially parallel to the respective adjacent branch 2 of the main rod 1; an elongated inflatable enclosure 8, produced individually in the form of an independent element, is introduced into said pocket 10.

La figure 4 montre un mode de réalisation préféré qui constitue une variante de réalisation de l'embarcation de la figure 3. Les deux flotteurs auxiliaires 7 sont, à l'état gonflé de la quille 6 et des enceintes 8, plaqués contre la face inférieure du fond 4 ; la toile de fond 5, tendue par la quille 6, forme une carène centrale en V s'étendant, transversalement, entre les deux flotteurs auxiliaires 7 ; enfin la paroi 11 des poches 10 qui est située latéralement vers l'extérieur s'étend obliquement et fait office de plan de sustentation latéral sur lequel s'exerce la portance, en lieu et place de la toile rapportée latéralement sur les branches bilobées des structures antérieures.Figure 4 shows a preferred embodiment which constitutes an alternative embodiment of the boat of Figure 3. The two auxiliary floats 7 are, in the inflated state of the keel 6 and the enclosures 8, pressed against the underside from the bottom 4; the backdrop 5, stretched by the keel 6, forms a central V-shaped hull extending transversely between the two auxiliary floats 7; finally the wall 11 of the pockets 10 which is located laterally towards the outside extends obliquely and acts as a lateral lift plane on which the lift is exerted, in place of the attached fabric laterally on the bilobed branches of the anterior structures.

Pour que la configuration montrée à la figure 4 puisse être obtenue par simple gonflage de la quille 6 et des deux enceintes 8, les poches 10 doivent être agencées comme représenté à la figure 5. Sur cette figure 5, la toile de fond 5 est représentée à plat, tendue, la quille 6 et les enceintes 8 n'étant pas gonflées. On voit que la paroi 12 des poches 10 qui est située latéralement vers l'intérieur a son bord longitudinal 13 qui est plaqué à plat sur la toile de fond 5 et qui est solidarisé à celle-ci en étant dirigé vers le bord le plus proche de ladite toile de fond. Le bord longitudinal de l'autre paroi 11 étant fixé de la même façon, l'asymétrie structurelle 1 de chaque poche 10 conduit, après gonflage des enceintes 8 et de la grille 6, à l'asymétrie de forme visible à la figure 4.So that the configuration shown in Figure 4 can be obtained by simply inflating the keel 6 and the two enclosures 8, the pockets 10 must be arranged as shown in Figure 5. In this Figure 5, the backdrop 5 is shown flat, taut, the keel 6 and the enclosures 8 not being inflated. It can be seen that the wall 12 of the pockets 10 which is located laterally inwards has its longitudinal edge 13 which is flat against the backdrop 5 and which is joined thereto while being directed towards the nearest edge of said backdrop. The longitudinal edge of the other wall 11 being fixed in the same way, the structural asymmetry 1 of each pocket 10 leads, after inflation of the enclosures 8 and of the grid 6, to the asymmetry of shape visible in FIG. 4.

La figure 6 est une vue de dessous en perspective de l'embarcation de la figure 4, permettant d'apprécier la forme longitudinale de la carène. Les deux flotteurs auxiliaires 7 s'étendent sur une longueur correspondant approximativement à la longueur des branches sensiblement parallèles 2 du boudin principal 1. Leur extrémité avant 14 se raccorde de façon profilée avec la toile de fond 5.Figure 6 is a bottom perspective view of the boat of Figure 4, to assess the longitudinal shape of the hull. The two auxiliary floats 7 extend over a length corresponding approximately to the length of the substantially parallel branches 2 of the main rod 1. Their front end 14 is connected in a profiled manner with the backdrop 5.

Comme il va de soi, et comme il résulte d'ailleurs déjà de ce qui précède, l'invention ne se limite nullement à ceux de ses modes d'application et de réalisation qui ont été plus spécialement envisagés ; elle en embrasse, au contraire, toutes les variantes.As goes without saying, and as it already follows from the above, the invention is in no way limited to those of its modes of application and embodiments which have been more especially envisaged; on the contrary, it embraces all its variants.
