Abstract
Description
La présenCe invention concerne des perfectionnements apportés aux navires de type trimarans, et-particulièrement aux trimarans à bras de liaison articulés. The present invention relates to improvements made to ships of the trimaran type, and in particular to trimarans with articulated link arms.
On sait que les trimarans sont pourvus sur chaque bord d'un ou plusieurs bras rigides terminés par des flotteurs appropriés, ou d'une seule poutre transversale au navire munie également de flotteurs. It is known that trimarans are provided on each edge with one or more rigid arms terminated by appropriate floats, or with a single beam transverse to the ship also provided with floats.
Des tentatives ont déjà été faites pour doter cet ensemble rigide coque centrale - bras de liaison de systèmes de sécurité, notamment pour prévenir les chavirements, les ruptures de liaison ou les démâtages. Parmi ces systèmes, on a pensé à articuler les bras de liaison au niveau de la coque centrale et à disposer sous les-dits bras des tirants extensibles fixés d'une part aux bras, d'autre part à la coque centrale. Ces dispositifs ne réagissaient qu'au-delà d'une certaine force; leur implantation et leur nature m8me les rendait vulnérables; ils n'ont pas été retenus à cause de leur fragilité. Attempts have already been made to provide this rigid central shell - link arm assembly with security systems, in particular to prevent capsizing, breakage of links or dismasting. Among these systems, it has been thought to articulate the link arms at the level of the central shell and to have under said arms extendable tie rods fixed on the one hand to the arms, on the other hand to the central shell. These devices only reacted beyond a certain force; their location and their very nature made them vulnerable; they were not selected because of their fragility.
La présente invention définit les zones d'implantation dans lesquelles il est possible d'installer sur les trimarans des sys tempes d'articulation, de suspension et d'amortissement entre les bras et le navire, offrant le maximum de solidité et dégageant tous les avantages attendus sur ce type de navire. The present invention defines the implantation zones in which it is possible to install on the trimarans systems of articulation, suspension and damping between the arms and the ship, offering the maximum solidity and releasing all the advantages. expected on this type of ship.
Les dessins annexés illustrent à titre indicatif et non limitatif quelques-unes des solutions exposées. Les 3 figures representent shématiquement un trimaran en coupe au niveau de l'un de ses bras de liaison. Un seul bord du navire a été détaillé, avec un seul bras et son flotteur. Il s'entend que dans le cas du trimaran, l'autre bord est symétrique à celui représenté. The accompanying drawings illustrate by way of non-limiting illustration some of the solutions presented. The 3 figures schematically represent a trimaran in section at one of its link arms. Only one edge of the ship has been detailed, with only one arm and its float. It is understood that in the case of the trimaran, the other edge is symmetrical to that shown.
La première caractéristique de l'invention consiste à implanter les points d'ancrage D des éléments de suspension et d'amorti tissement A d'une part sur es bras > de liaison 8 ou de leur prolongement au-delà de leur axe de rotation C (figure 3), d'autre part soit sur le pont du navire (figure 1), soit à l'intérieur mame du navire (fig 2 et 3). Dans le cas d'implantation sur le pont du naùire, - on peut disposer des structures de renfort propres à recevoir l-es points d'ancrage, notamment si diverses superstructures occupant la totalité du pont par exemple, obligent une implantation située au-dessus de la surface du pont.Par ailleurs, ces structures de renfort peuvent être une poutre disposée perpendiculairement a l'axe du navire, au-dessus ou au-dessous de la surface du pont et prolongeant le pont soit en hauteur, soit en largeur au-delà des bords du navire. The first characteristic of the invention consists in implanting the anchor points D of the suspension and damping elements A on the one hand on the link arms 8 or their extension beyond their axis of rotation C (Figure 3), on the other hand either on the deck of the ship (Figure 1), or inside the same vessel (fig 2 and 3). In the case of installation on the ship’s bridge, - reinforcement structures suitable for receiving the anchoring points may be available, in particular if various superstructures occupying the entire bridge for example, require an installation located above of the surface of the bridge.Moreover, these reinforcing structures may be a beam placed perpendicular to the axis of the ship, above or below the surface of the bridge and extending the bridge either in height or in width at beyond the edges of the ship.
Une autre caractéristique de l'invention consiste à disposer les-dits points d'ancrage dans l'axe de rotation des bras d'une part, et dans le prolongement de cet axe d'autre part. Cette disposition permet l'installation de suspensions à barres de torsion, ou de déporter longitudinalement l'implantation d'un autre système. Another characteristic of the invention consists in placing the said anchor points in the axis of rotation of the arms on the one hand, and in the extension of this axis on the other hand. This arrangement allows the installation of torsion bar suspensions, or to offset the installation of another system longitudinally.
Par ces caractéristiques, on comprend que l'on peut adapter aux trimarans ou navires à bras articulés tous les systèmes de suspension et d'amortissement les plus en usage et les plus solides connus actuellement sur les véhicules terrestres ou autres ressorts hélicordaux, cantilever, lames, suspensions pneumatiques et hydrauliques, barres de torsion, etc. et ce dans des zones plus à l'abri et plus accessibles que dans les études précédentes. By these characteristics, it is understood that one can adapt to trimarans or ships with articulated arms all the suspension and damping systems most in use and the strongest known currently on land vehicles or other helical springs, cantilever, blades , pneumatic and hydraulic suspensions, torsion bars, etc. and this in more sheltered and more accessible areas than in previous studies.
Le principal avantage attendu de l'invention est le contrôle continu et progressif des forces et contraintes subies par les bras de liaison dans les surventes et dans la mer formée. La résistance des bras sera accrue, les risques de chavirage et de démâtage seront diminués. Selon le type de navigation recherchée, on pourra adapter à tel navire des suspensions dures qui lui donneront des performances maximales, et à tel autre des suspensions souples et à grand débattement qui lui donneront davantage de gtte mais plus de sécurité et une meilleure résistance de toutes les structures. The main expected advantage of the invention is the continuous and progressive control of the forces and stresses undergone by the link arms in oversold and in rough seas. The resistance of the arms will be increased, the risks of capsizing and dismasting will be reduced. Depending on the type of navigation sought, it will be possible to adapt to such a vessel hard suspensions which will give it maximum performance, and to such another flexible and long-travel suspensions which will give it more heel but more safety and better resistance of all the structures.
Une autre caractéristique de l'invention consiste en ce que les organes de suspension et d'amortissement sont démontables, pa exemple au moyen de clavetage sur leurs axes d'ancrage, et que les ensembles bras-flotteurs sont entièrement relevables au-dessus du pont, par exemple au moyen d'un bout et diune poulie fixée au mât à hauteur convenable. Si la stabilité initiale des formes de la coque est insuffisante, on descendra au-préalable une dérive lestée. Il est attendu de cette caractéristique un encombrement réduit au port. Another characteristic of the invention consists in that the suspension and damping members are removable, pa for example by keying on their anchor pins, and that the arm-float assemblies are fully liftable above the bridge , for example by means of an end and a pulley fixed to the mast at a suitable height. If the initial stability of the hull shapes is insufficient, a ballasted drift will be lowered beforehand. This characteristic is expected to reduce the size of the port.
Suivant une autre caractéristique de l'invention, chaque bras de liaison de chaque bord peut être articulé, suspendu et amorti d'une façon indépendante. Il en découle, dans le cas d'un ensemble de bras d'un même bord, la faculté d'une correction automatique de l'assiette du flotteur solidaire de ces bras, si l'on installe entre ces bras et ce flotteur une liaison articulée,
Suivant une autre caractéristique de l'invention, les ensembles de bras d'un meme bord pourront au contraire Qtre solidarisés à un quelconque niveau y compris celui de leurs axes, afin de les accoupler à un seul système de suspension et d'amortissement.According to another characteristic of the invention, each link arm of each edge can be articulated, suspended and damped independently. It follows, in the case of a set of arms of the same edge, the ability to automatically correct the attitude of the float secured to these arms, if a connection is installed between these arms and this float articulated,
According to another characteristic of the invention, the sets of arms of the same edge may on the contrary be joined at any level, including that of their axes, in order to couple them to a single suspension and damping system.
D'autre part, les'points d'articulation de chique bras ou ensemble de bras peuvent être implantés de plusieurs façons, notamment sur chaque bord du navire, mais aussi, selon une autre caractéristique de l'invention, à chaque extrémité d'une amorce de poutre transversale au navire, dépassant les bords et solidaire du pontage ou de la coque à un niveau supérieur ou inférieur au pont; ou encore, selon une autre caractéristique, ces bras ou ensembles de bras peuvent avoir leurs points d'articulations dans l'axe mé dian du pont du navire, où les axes d'articulation des bras des 2 bords peuvent être confondus en un seul axe. Cette disposition particulière favorise l'implantation de certains systemes de suspension, notamment disposés à l'intérieur du navire. (fig 2). On the other hand, the points of articulation of the arm or set of arms can be installed in several ways, in particular on each edge of the ship, but also, according to another characteristic of the invention, at each end of a start of beam transverse to the ship, beyond the edges and integral with the decking or the hull at a level higher or lower than the deck; or, according to another characteristic, these arms or sets of arms can have their points of articulation in the median axis of the deck of the ship, where the axes of articulation of the arms of the 2 edges can be merged into a single axis . This particular arrangement favors the installation of certain suspension systems, in particular arranged inside the ship. (fig 2).
Les caractéristiques de cette invention, conçue spécialement pour les trimarans, pourront s'appliquer à tout autre type de navire sur lequel on peut adapter les systèmes tels que décrits dans l'invention, alors meme que ce navire n'aurait pas dans sa conception et réalisation initiale la dénomination de trimaran, ainsi les monocoques, les catamarans9 les praos etc. The characteristics of this invention, specially designed for trimarans, can be applied to any other type of ship on which the systems as described in the invention can be adapted, even though this ship would not have been in its design and initial realization the name of trimaran, thus monohulls, catamarans9 praos etc.
