Abstract

The assembly has a top rigid rectangular plan plate which forms the top deck (1) of the boat, and a lower rigid plate that has a rectangular projection but which has a considerable concavity turned towards the top plate and which forms the boat keel (2). The plates are stably matched to each other along respective edges (3,4) so that their assembly forms a sealed chamber. This assembly is fixed to the covers (5,6) of the inflatable air chambers, or directly to the chambers themselves, via bolts (8) passing through appropriate mountings (10).

Description

La présente invention concerne un dispositif pour réaliser la liaison amovible d'un pont supérieur et d'une carène, rigides, aux couvertures des chambres à air enflables d'un bateau pneumatique.The present invention relates to a device for making the removable connection of an upper deck and a rigid hull to the covers of the inflatable air chambers of an inflatable boat.

Les bateaux pneumatiques de dimensions relativement grandes, qui ont, pour exemple, une longueur comprise entre quatre et huit mètres, et qui sont destinés au transport d'un nombre approprié de personnes ou de charges pro- portionées et aussi à gagner le large jusqu'à une distance considérable de la côte, sont pourvus pour la plupart, comme chacun sait, d'un corps flottant, lequel comprend un certain nombre de chambres à air enflables avec de l'air comprimé qui sont placées convenablement dans une enveloppe de couverture protectrice.Inflatable boats of relatively large dimensions, which have, for example, a length of between four and eight meters, and which are intended for the transport of an appropriate number of persons or proportionate loads and also to sail offshore to at a considerable distance from the coast, most of them are provided, as everyone knows, with a floating body, which includes a number of inflatable chambers with compressed air which are suitably placed in a protective covering envelope .

Jusqu'à ce que la longueur du bateau ne dépasse pas les trois - quatre mètres, la tâche de remplir la double fonction de "carène" et de pont supérieur " peut être confiée avantageusement à un seul élément aplanissant, rigide ou opportunément raidi. Mais si la longueur du bateau dépasse cette valeur, l'emploi d'un seul élément aplanissant présente des difficultes remarquables.Until the length of the boat does not exceed three - four meters, the task of fulfilling the dual function of "hull" and upper deck "can advantageously be entrusted to a single planar, rigid or expediently stiffened element. But if the length of the boat exceeds this value, the use of a single planarizing element presents remarkable difficulties.

Le but de la présente invention est de réaliser un groupe pont supérieur - carène comprenant au moins deux éléments en forme de plaques de matériel rigide (métallique, pour exemple) qui forment ensemble une chambre tout à fait étanche laquelle est pourvue au moins d'un bord saillant (bride), plus ou moins long, opportunément incliné et tel qu'il peut être posé le long d'une ligne longitudinale à l'égard des couvertures des chambres à air existantes; ce même bord étant pourvu d'une pluralité de trous percants unifomément disposés, de manière à ce qu'il peut être fixé aux couvertures susnommées au moyen de boulons qui agissent à l'aide de spéciaux éléments pressants qui peuvent être insérés partiellement l'un dans l'autre.The object of the present invention is to produce an upper deck - hull group comprising at least two elements in the form of plates of rigid material (metallic, for example) which together form a completely sealed chamber which is provided with at least one protruding edge (flange), more or less long, suitably inclined and as it can be laid along a longitudinal line with respect to the covers of the existing air chambers; this same edge being provided with a plurality of uniformly arranged piercing holes, so that it can be fixed to the abovementioned covers by means of bolts which act by means of special pressing elements which can be partially inserted one in the other.

Le dispositif formant l'objet de la présente invention sera décrit ci-après en détail pour une meilleure compréhension par rapport aux dessins ci-joints qui le représentent selon la préférée et la plus simple forme d'exécution. Dans les dessins susnommés:

  • - les figures 1 et 2 sont deux vues, respectivement du dessus et de côté, d'un bateau pneumatique conforme à l'invention;
  • - la figure 3 est une section de même bateau tracée suivant la ligne A-A de la figure 1;
  • - La figure 4 représente, en échelle plus grande, partiellement en section et selon une vue axonométrique, deux couvertures pour chambres à air auxquelles on trouve fixé l'ensemble formant la chambre étanche, les bord inclinés duquel sont précisément fixés aux mêmes couvertures;
  • - les figures 5, 6 et 7 sont des vues qui rep*résentent, en échelle plus grande, les éléments pressants qui permettent, au moyen d'appropriés boulons, de presser uniformément sur les couvertures de manière à établir la liaison en étanchéité entre les mêmes couvertures et la chambre étanche;
  • - la figure 8, enfin, est une section, en échelle encore plus grande, qui montre partiellement la manière dont on obtient, au moyen d'un boulon et d'un élément pressant, la liaison d'une couverture avec la chambre étanche située au dessous.
The device forming the object of the present invention will be described below in detail for a better understanding with respect to the attached drawings which show it according to the preferred and the simplest embodiment. In the above-mentioned drawings:
  • - Figures 1 and 2 are two views, respectively from above and from the side, of an inflatable boat according to the invention;
  • - Figure 3 is a section of the same boat drawn along the line AA in Figure 1;
  • - Figure 4 shows , on a larger scale, partially in section and in an axonometric view, two covers for air chambers to which the assembly forming the sealed chamber is found, the inclined edges of which are precisely fixed to the same covers;
  • - Figures 5, 6 and 7 are views which represent *, on a larger scale, the pressing elements which allow, by means of appropriate bolts, to press uniformly on the covers so as to establish the sealing connection between the same blankets and waterproof chamber;
  • - Figure 8, finally, is a section, in even larger scale, which partially shows the way in which one obtains, by means of a bolt and a pressing element, the connection of a cover with the sealed chamber located below.

Le dispositif fomant l'objet de la présente invention comprend un ensemble qui constitue une chambre étanche qui se compose, pour exemple et selon la forme d'exécution la plus simple, d'une plaque supérieure 1, préférablement métallique, ayant un plan essentiellement rectangulaire et destinée à former le " pont supérieur ", et une plaque inférieure 2, elle aussi préférablement métallique, qui a un plan essentiellement rectangulaire, est pliée à angle dièdre et est destinée à former la " carène "; les mêmes deux plaques étant jointes l'une à l'autre le long des bords 3 et 4 (comme on peut voir dans les figures 3 et 4) et les susnommés bords, qui pourront être plus ou moins larges, étant pourvus d'une pluralité de trous perçants uniformément disposés. Les bords 3 et 4 sont reliés aux couvertures 5 et 6 au moyen de boulons, tels 8, dont les tiges percent les parois des mêmes couvertures suivant des lignes longitudinales, comme on voit dans la figure 4. Entre chaque boulon et le matériel des couvertures un élément pressant spécial, tel 10, est inséré, qui a la tâche de rendre uniforme la pression sur une surface relativement étendue.The device forming the object of the present invention comprises an assembly which constitutes a sealed chamber which is composed, for example and according to the simplest embodiment, of an upper plate 1, preferably metallic, having an essentially rectangular plane and intended to form the "upper deck", and a lower plate 2, also preferably metallic, which has an essentially rectangular plane, is folded at a dihedral angle and is intended to form the "hull"; the same two plates being joined to each other along the edges 3 and 4 (as can be seen in Figures 3 and 4) and the above-mentioned edges, which may be more or less wide, being provided with a plurality of uniformly arranged piercing holes. The edges 3 and 4 are connected to the covers 5 and 6 by means of bolts, such 8, the rods of which pierce the walls of the same covers along longitudinal lines, as seen in Figure 4. Between each bolt and the material of the covers a special pressing element, such as 10, is inserted, which has the task of making the pressure uniform over a relatively large area.

L'élément pressant 10 susnommé se compose essentiellement d'un seul petit bloc rigide, inscriptible dans un parallélepipède allonge, et se termine aux deux extrémités mineures opposées respectivement avec une saillie à V et avec un creusement à V aussi, ce qui permet à chacun élément pressant de s'insérer partiellement dans l'élément contigu. Les figures 5,6 et 7 montrent le fonctionnement de l'élément pressantThe aforementioned pressing element 10 essentially consists of a single small rigid block, inscribable in an elongated parallelepiped, and ends at the two opposite opposite ends respectively with a projection at V and with a digging at V also, which allows each pressing element to fit partially into the adjoining element. Figures 5,6 and 7 show the operation of the pressing element

Dans le but d'aussurer la parfaite étanchèité entre la chambre étanche (1-2) et les couvertures (5-6) des chambres à air, entre les couvertures susnommées et les bords (3-4) de la même chambre étanche on a prévu d'employer une garniture rubanaire en elastomère 12, comme on voit clairement dans la figure 8.In order to aussurer the perfect seal between the sealed chamber (1-2) and the covers (5-6) of c h amber air between the above-named cover and the edges (3-4) of the sealed chamber provision has been made to use an elastomeric band seal 12, as can be clearly seen in FIG.

En outre on a prévu l'emploi d'une garniture conique 13, préférablément en elastomère, pour perfectionner l'étanchéité entre la tête du boulon 8 et l'ensemble pont supérieur - carène " (3-4). Il va sans dire que la conformation de l'élément qui est destiné à constituer la carène du bateau et à être joint à l'élément qui est destiné à en constituer le pont supérieur pourra être réalisé autrement que ce qui est décrit et illustré ci-dessus, c'est à dire qu'il pourra être differant d'un simple dièdre et que l'axe longitudinal de quelques éléments pressants pourra être, plutôt rectiligne, légèrement recourbé pour permettre aux mêmes éléments d'agir efficacément sur les couvertures en suivant leur configuration. Tout ça sans sortir des limites de protection du brevet.In addition, provision has been made for the use of a conical packing 13, preferably made of elastomer, to improve the seal between the head of the bolt 8 and the upper deck - hull assembly "(3-4). It goes without saying that the shape of the element which is intended to constitute the hull of the boat and to be joined to the element which is intended to constitute the upper deck thereof may be achieved otherwise than what is described and illustrated above, that is to say that it could be different from a simple dihedral and that the longitudinal axis of some pressing elements could be, rather rectilinear, slightly curved to allow the same elements to act effectively on the covers according to their configuration. without going beyond the limits of patent protection.

Il est évident aussi, en des cas spéciaux, que la chambre étanche, qui se compose d'un pont supérieur et d'une carène, peut être reliée directement aux chambres à air gonflabes avec air en pression.It is also obvious, in special cases, that the sealed chamber, which consists of an upper deck and a hull, can be connected directly to the inflatable air chambers with pressurized air.
