Description

L'invention est relative à la conception et à la réalisation des trimarans., notamment, mais non exclusivement à voile.The invention relates to the design and production of trimarans., In particular, but not exclusively by sail.

Les enseignements résultants des nombreuses compétitions sportives de navigation à voile comportent deux aspects principaux antinomiques : d'une part, les bateaux les plus rapides par vent fort sont ceux possédant plusieurs flotteurs, et, notamment, les trimarans d'autre part, ces bateaux les plus rapides ont une résistance mécanique insuffisante et sont, de ce fait, l'objet de nombreuses avaries en mer. Ce deuxième aspect est lié aux valeurs très grandes des contraintes mécaniques auxquelles la structure d'un bateau multicoque, tel qu'un trimaran, est soumise tout particulièrement dans les éléments de jonction ou de liaison des divers flotteurs. En outre, on constate également une certaine dégradation de la stabilité des trimarans, au-delà d'uhe limite d'utilisation, à partir de laquelle un tel bateau, de très stable devient subitement très instable.The lessons learned from the numerous sporting sailing competitions have two main contradictory aspects: on the one hand, the fastest boats in strong winds are those with several floats, and, in particular, trimarans on the other hand, these boats faster have insufficient mechanical strength and are therefore subject to numerous damages at sea. This second aspect is linked to the very large values of the mechanical stresses to which the structure of a multihull boat, such as a trimaran, is particularly subject to the joining or linking elements of the various floats. In addition, there is also a certain deterioration in the stability of the trimarans, beyond a limit of use, from which such a boat, from very stable suddenly becomes very unstable.

Ces divers inconvénients sont en rapport avec une inadaptation complète des structures connues à ce jour des trimarans, de sorte qu'il ne peut y être remédié que par l'adoption de structures de type entièrement nouveau.These various drawbacks are related to a complete inadequacy of the structures known to date from trimarans, so that it can only be remedied by the adoption of entirely new type structures.

L'invention est relative à un trimaran comprenant trois flotteurs formant un système de flottaison statique de trois zones de flottaison disposées aux sommets d'un triangle, et, un pont auquel ces trois flotteurs sont reliés, cependant que, d'une part, chacun des trois flotteurs est monté pivotant par rapport au pont autour d'au moins un axe, l'un des axes de pivotement étant sensiblement vertical, et que, d'autre part, chaque flotteur relié au pont par un axe de pivotement sensiblement vertical est muni d'un aileron de stabilisation disposé verticalement en arrière dudit axe de pivotement sensiblement vertical.The invention relates to a trimaran comprising three floats forming a static flotation system of three flotation zones arranged at the vertices of a triangle, and, a bridge to which these three floats are connected, while, on the one hand, each of the three floats is pivotally mounted relative to the bridge around at least one axis, one of the pivot axes being substantially vertical, and that, on the other hand, each float connected to the bridge by a substantially vertical pivot axis is fitted with a fin stabilization disposed vertically behind said substantially vertical pivot axis.

Cette invention a pour but de remédier aux inconvénients précités et pour objet de proposer de nouvelles structures aptes à atteindre ce but.The object of this invention is to remedy the aforementioned drawbacks and its object is to propose new structures capable of achieving this aim.

A cet effet, un flotteur au moins est muni d'un aileron, dit, de manoeuvre, qui

  • . est sensiblement vertical,
  • . est monté pivotant par rapport au flotteur autour d'un axe de pivotement sensiblement vertical disposé en avant de l'axe sensiblement vertical de pivotement du flotteur par rapport au pont, et,
  • . est muni d'un dispositif de réglage de son pivotement.
To this end, at least one float is provided with a so-called maneuvering fin which
  • . is substantially vertical,
  • . is pivotally mounted relative to the float about a substantially vertical pivot axis disposed in front of the substantially vertical pivot axis of the float relative to the bridge, and,
  • . is provided with a device for adjusting its pivoting.

Les avantageuses dispositions suivantes, sont, en outre, de préférence adoptées :

  • - l'aileron de stabilisation est, soit fixe par rapport audit flotteur, soit monté pivotant par rapport au flotteur autour d'un axe vertical, et, est alors muni d'un dispositif de réglage de son pivotement ;
  • - lorsque le trimaran comporte un gréement de voilier, ce gréement est monté sur une poutre, qui s'étend sensiblement horizontalement et est montée sur le pont au moyen d'un dispositif de liaison en permettant le pivotement parallèlement à trois directions orthogonales ;
  • - un dispositif de réglage de la position de la poutre par rapport à son dispositif de liaison,tel qu'une glissière de coulissement associée à un organe de maintien en position, est prévu.
The following advantageous arrangements are also preferably adopted:
  • - The stabilization fin is either fixed relative to said float, or pivotally mounted relative to the float about a vertical axis, and, is then provided with a device for adjusting its pivoting;
  • - When the trimaran has a sailboat rigging, this rigging is mounted on a beam, which extends substantially horizontally and is mounted on the deck by means of a connecting device allowing the pivoting parallel to three orthogonal directions;
  • - A device for adjusting the position of the beam relative to its connecting device, such as a sliding slide associated with a member for holding in position, is provided.

L'avantage principal du trimaran revendiqué réside dans l'obtention à la fois d'une bonne stabilisation des flotteurs, et une bonne manoeuvrabilité, dues à l'adoption simultanée des ailerons de stabilisation, d'une part, de manoeuvre, d'autre part.The main advantage of the claimed trimaran lies in obtaining both good stabilization of the floats and good maneuverability, due to the simultaneous adoption of the stabilization fins, on the one hand, and of maneuvering, on the other hand go.

L'invention sera mieux comprise, et des caractéristiques secondaires et leurs avantages apparaîtront au cours de la description d'une réalisation donnée ci-dessous à titre d'exemple.The invention will be better understood, and secondary characteristics and their advantages will appear during the description of an embodiment given below by way of example.

Le voilier représenté est un trimaran et comporte, dans la configuration des dessins, par rapport à un trièdre tri- rectangle de référence Oxyz, dans lequel Ox est l'axe longitudinal horizontal du voilier orienté vers l'avant, Oy est un axe horizontal transversal, Oz est un axe vertical ascendant :

  • - un flotteur avant 1, décalé transversalement par rapport à l'axe longitudinal0x, situé à babord,
  • - un autre flotteur avant 2, identique au précédent et placé à tribord, symétriquement au flotteur 1 par rapport au plan xOz,
  • - un flotteur arrière 3, situé en arrière des deux flotteurs avant 1 et 2 et symétriquement par rapport au plan xOz, qui constitue donc, dans la configuration décrite, le plan médian à la fois du flotteur arrière 3 et du trimaran,
  • - un pont 4, qui présente de nombreuses échancrures, qui est relié aux flotteurs par divers bras (5 et 6, pour la liaison à chacun des flotteurs avant 1, 2, et, 7 et 8 pour la liaison au flotteur arrière 3), et qui supporte à sa partie arrière, l'abri de navigation 9 de l'équipage,
  • - une poutre 10, qui est disposée à l'avant du pont 4, transversalement parallèlement au plan yOz, en s'étendant sensiblement horizontalement et en étant maintenue en position par rapport au pont 4, en une position réglable, notamment au moyen de filins 11 en reliant ses extrémités à l'abri de navigation 9,
  • - un mât 12, qui s'élève verticalement en ayant sa base fixée sur la poutre 10,
  • - une grand'voile 13 qui est supportée par le mât 12 et s'étend sensiblement parallèlement au plan yOz.
The sailboat represented is a trimaran and comprises, in the configuration of the drawings, with respect to a trihedral t ri- rectangle of reference Oxyz, in which Ox is the horizontal longitudinal axis of the sailboat facing forward, Oy is a horizontal axis transverse, Oz is an ascending vertical axis:
  • - a front float 1, offset transversely to the longitudinal axis l 0x, located on the port side,
  • - another forward float 2, identical to the previous one and placed on the starboard side, symmetrically with the float 1 relative to the plane xOz,
  • a rear float 3, located behind the two front floats 1 and 2 and symmetrically with respect to the plane xOz, which therefore constitutes, in the configuration described, the median plane of both the rear float 3 and the trimaran,
  • - a bridge 4, which has many notches, which is connected to the floats by various arms (5 and 6, for the connection to each of the front floats 1, 2, and, 7 and 8 for the connection to the rear float 3), and which supports at its rear part, the navigation shelter 9 of the crew,
  • - A beam 10, which is arranged in front of the bridge 4, transversely parallel to the plane yOz, extending substantially horizontally and being held in position relative to the bridge 4, in an adjustable position, in particular by means of ropes 11 by connecting its ends to the navigation shelter 9,
  • - a mast 12, which rises vertically with its base fixed on the beam 10,
  • - A mainsail 13 which is supported by the mast 12 and extends substantially parallel to the plane yOz.

Les dispositifs de liaison du pont 4 aux flotteurs sont particuliers. Celui relatif au flotteur avant tribord 2 est décrit ci-après. Un support 14 en T, la jambe 15 orientée vers le haut et la barre 16 du T étant horizontale, est monté pivotant, autour d'un axe géométrique A parallèle à l'axe Oy, au moyen des deux parties de la barre 16 du T qui constituent des tourillons et reposent dans des coussinets 17 fixés sur le flotteur 2. La jambe verticale 15 du support 14 constitue un tourillon et permet le montage pivotant autour d'un axe géométrique vertical B du bras 6 et du bras 5, tous deux soudés (18) à un même coussinet 19. Les extrémités 5a et 6a, opposées au coussinet 19, sont munies d'embouts à rotules 20 qui sent, d'une part, fixés au pont 4 par des axes horizontaux 21 sensiblement perpendiculaires au bras considéré (5 ou 6), d'autre part, fixés au bras considété (5 ou 6) par leur partie filetée (22,23). A noter qu'un vérin 24 est disposé entre chaque bras 6 et le pont 4 et permet, soit de régler la position dudit bras par rapport au pont, soit de réaliser une suspension souple, lorsque sa chambre active est reliée à un accumulateur de gaz sous pression. A noter également que le flotteur arrière 3 est, lui aussi, relié au pont 4 au moyen d'un support 14 qui permet les pivotements autour d'axes A horizontal et B vertical.The devices for connecting the deck 4 to the floats are specific. The one relating to the starboard forward float 2 is described below. A support 14 in T, the leg 15 oriented upwards and the bar 16 of the T being horizontal, is pivotally mounted, around a geometric axis A parallel to the axis Oy, by means of the two parts of the bar 16 of the T which constitute trunnions and rest in bearings 17 fixed on the float 2. The vertical leg 15 of the support 14 constitutes a trunnion and allows the mounting pivoting around a vertical geometric axis B of the arm 6 and of the arm 5, both welded (18) to the same pad 19. The ends 5a and 6a, opposite to the pad 19, are provided with ball-end fittings 20 which, on the one hand, feels fixed to the bridge 4 by horizontal axes 21 substantially perpendicular to the arm considered (5 or 6), on the other hand, fixed to the arm considered (5 or 6) by their threaded part (22,23). Note that a jack 24 is disposed between each arm 6 and the bridge 4 and allows either to adjust the position of said arm relative to the bridge, or to make a flexible suspension, when its active chamber is connected to a gas accumulator under pressure. Note also that the rear float 3 is also connected to the deck 4 by means of a support 14 which allows pivoting around axes A horizontal and B vertical.

Le dispositif de fixation de la poutre 10 comprend :

  • - un palier 25, d'axe vertical 26, ménagé dans le pont 4,
  • - un tourillon 27, monté dans le palier 25 et muni, sur sa tranche supérieure, d'un support 28 d'un axe horizontal 29 (parallèle, dans la configuration représentée, à Ox),
  • - une pièce intermédiaire 30, qui est montée pivotante sur le support 28 autour de l'axe 29,
  • une glissière 31 montée pivotante à la partie supérieure de la pièce intermédiaire 30 autour d'un axe horizontal 32, orthogonal à l'axe 29,
  • -quatre galets 33 et 34, à axes obliques les uns rapport aux autres, portés par la glissière 31, et constituant un dispositif de guidage et d'appui pour un rail 35 disposé à la partie inférieure de la poutre 10, la direction du coulissement du rail 35 par rapport à la glissière 31 étant sensiblement parallèle à l'axe 32. Le dispositif de coulissement -glissière 31, rail 35, galets 33, 34- est connu en soi (par exemple, marque "BARBAROSSA").
The device for fixing the beam 10 comprises:
  • a bearing 25, with a vertical axis 26, formed in the deck 4,
  • a pin 27, mounted in the bearing 25 and provided, on its upper edge, with a support 28 of a horizontal axis 29 (parallel, in the configuration shown, to Ox),
  • an intermediate piece 30, which is pivotally mounted on the support 28 around the axis 29,
  • a slide 31 pivotally mounted at the upper part of the intermediate piece 30 around a horizontal axis 32, orthogonal to the axis 29,
  • -four rollers 33 and 34, with oblique axes relative to each other, carried by the slide 31, and constituting a guide and support device for a rail 35 disposed at the bottom of the beam 10, the direction of sliding of the rail 35 relative to the slide 31 being substantially parallel to the axis 32. The sliding device-slide 31, rail 35, rollers 33, 34- is known per se (for example, brand "BARBAROSSA").

Ainsi, la poutre 10 peut osciller autour. de trois axes orthogonaux (26, 29, 32) et coulisser parallèlement à son propre axe.Thus, the beam 10 can oscillate around. three orthogonal axes (26, 29, 32) and slide parallel to its own axis.

Chaque flotteur est, en outre, muni d'ailerons sensiblement verticaux, contenus dans le plan longitudinal vertical de symétrie du flotteur.Each float is, moreover, provided with substantially vertical fins, contained in the vertical longitudinal plane of symmetry of the float.

Chacun des flotteurs avant 1, 2, comprend :

  • - un aileron 36, qui est monté pivotant autour d'un axe sensiblement vertical 37 disposé à l'avant du flotteur, nettement en avant de l'axe B du dispositif 14 correspondant au flotteur concerné ; cet aileron a, en outre, son orientation autour de l'axe 37 réglable au moyen d'un dispositif connu 38 de commande à distance depuis l'abri de navigation 9, tel que les dispositifs commercialisés sous la marque "W. H. DEN OUDEN, VETUS" ;
  • - un aileron 39, qui est monté pivotant autour d'un axe sensiblement vertical 40 disposé à l'arrière du flotteur, nettement en arrière de l'axe B du dispositif 14 cet aileron 39 a de plus, son orientation autour de l'axe 40 réglable au moyen d'un autre dispositif 38 de commande à distance depuis l'abri de navigation 9.
Each of the front floats 1, 2 includes:
  • - A fin 36, which is pivotally mounted about a substantially vertical axis 37 disposed in front of the float, clearly in front of the axis B of the device 14 corresponding to the float concerned; this fin has, in addition, its orientation around the axis 37 adjustable by means of a known device 38 for remote control from the navigation shelter 9, such as the devices marketed under the brand "WH DEN OUDEN, VETUS ";
  • - A fin 39, which is pivotally mounted about a substantially vertical axis 40 disposed at the rear of the float, clearly behind the axis B of the device 14 this fin 39 also has its orientation around the axis 40 adjustable by means of another device 38 for remote control from the navigation shelter 9.

Le flotteur arrière 3 comprend :

  • - un aileron 41, monté pivotant autour d'un axe vertical 42 situé en avant de l'axe B du dispositif 14, mais cette fois, voisin dudit axe B ; l'aileron 41 est également muni d'un dispositif 38 de commande à distance de son orientation ;
  • - un aileron 43, fixe par rapport au flotteur 3 et situé à l'arrière de ce flotteur, nettement en arrière de l'axe B du dispositif 14.
The rear float 3 includes:
  • - A fin 41, pivotally mounted about a vertical axis 42 located in front of the axis B of the device 14, but this time near said axis B; the fin 41 is also provided with a device 38 for remote control of its orientation;
  • - a fin 43, fixed relative to the float 3 and situated at the rear of this float, clearly behind the axis B of the device 14.

Le trimaran, qui a été décrit, possède des qualités nautiques et de manoeuvrabilité exceptionnelles, en rapport, notamment, avec :

  • - la conception même à trois flotteurs 1, 2 et 3;
  • - la pénétration correcte de chaque flotteur dans la mer, du fait du maintien possible de ces flotteurs dans les meilleures configurations de flottabilité, par suite des possibilités d'inclinaison très grandes autour d'axes horizontaux (A, 21) par rapport au pont 4 ;
  • - principalement, l'obtention, d'une part, de l'autostabilisation des flotteurs du fait de leur orientation possible autour d'axes verticaux (B) et des ailerons, dits, de stabilisation 39, 43 dont ils sont munis, d'autre part, du réglage des angles entre l'axe longitudinal de chaque flotteur et la direction d'avancement du trimaran au moyen du réglage de l'orientation des ailerons, dits, de manoeuvre 36, 41 ;
  • - également, la manoeuvre aisée de la voile principale 13 du fait des réglages complets possibles des orientations de la poutre 10 autour des trois axes 26, 29, 32, et de son coulissement dans la glissière 31.
The trimaran, which has been described, has exceptional nautical and maneuverability qualities, in particular, in relation to:
  • - the design itself with three floats 1, 2 and 3;
  • - the correct penetration of each float into the sea, due to the possible maintenance of these floats in the best buoyancy configurations, due to the very large inclination possibilities around horizontal axes (A, 21) relative to deck 4 ;
  • - mainly, obtaining, on the one hand, the self-stabilization of the floats because of their possible orientation around vertical axes (B) and the ailerons, said, of stabilization 39, 43 with which they are provided, on the other hand, the adjustment of the angles between the longitudinal axis of each float and the direction of advance of the trimaran by means of the adjustment of the orientation of the ailerons, called the maneuvering fins 36, 41;
  • - also, the easy maneuvering of the main sail 13 due to the possible complete adjustments of the orientations of the beam 10 around the three axes 26, 29, 32, and of its sliding in the slide 31.

Les réticences certaines que formulaient de nombreux utilisateurs vis-à-vis des trimarans connus ne peuvent plus être maintenues vis-à-vis de la nouvelle construction proposée. Celle-ci va donc rendre viables des bateaux qui ne l'étaient pas auparavant et qui, pour ce motif, étaient peu adoptés malgré leurs avantages connus de vitesses élevées.The reluctance that many users expressed with regard to known trimarans can no longer be maintained vis-à-vis the new construction proposed. This will therefore make viable boats that were not previously and which, for this reason, were not widely adopted despite their known advantages of high speeds.

L'invention n'est pas limitée à la réalisation décrite, mais en couvre au contraire toutes les variantes qui pourraient lui être apportées sans sortir de son cadre, ni de son esprit.The invention is not limited to the embodiment described, but on the contrary covers all the variants which could be made to it without departing from its scope or its spirit.
