Description

Catamaran articule» Articulating catamaran »
La présente invention concerne un bateau du type catamaran, c'est-à-dire comportant deux coques ou flot¬ teurs réunis par une armature ou un habitacle.The present invention relates to a catamaran type boat, that is to say comprising two hulls or floats assembled by a frame or a passenger compartment.
On sait que ce type de bateau présente une bonne stabilité et est doué d'une vitesse améliorée par rap¬ port aux bateaux monocoques. Toutefois, du fait même de sa conception, des efforts qui peuvent être importants par qros temps sont transmis aux liaisons entre les coques ou flotteurs et l'ossature qui les relie» Le but de l'invention est de permettre la réali¬ sation d'un bateau de ce type agencé de manière à sup¬ primer les efforts sur les liaisons entre les coques ou flotteurs et l'armature les réunissant, permettant éga¬ lement aux flotteurs de se débattre dans deux plans parallèles au plan de symétrie du navire, indépendamment l'un de l'autre, et suivant la forme de la surface li¬ quide, en obtenant ainsi un meilleur chevauchement des vagues et une meilleure tenue par gros temps.We know that this type of boat has good stability and is endowed with an improved speed compared to monohull boats. However, by the very fact of its design, efforts which can be significant in certain times are transmitted to the connections between the hulls or floats and the framework which connects them. The aim of the invention is to allow the realization of a boat of this type arranged so as to suppress the efforts on the connections between the hulls or floats and the frame uniting them, also allowing the floats to struggle in two planes parallel to the plane of symmetry of the ship, independently one from the other, and depending on the shape of the liquid surface, thereby obtaining better overlapping of the waves and better resistance in heavy weather.
Un autre but de l'invention est de réaliser un bateau de ce type agencé de telle sorte que l'habitacle prévu sur l'ossature reliant les flotteurs, conserve de façon permanente une position horizontale.Another object of the invention is to provide a boat of this type arranged so that the cabin provided on the frame connecting the floats, permanently retains a horizontal position.
Au total, l'invention vise un bateau alliant à la fois des qualités de bonne tenue de mer, de vitesse* de stabilité de l'habitacle, convenant tout particuliè¬ rement aux bateaux de plaisance, de transport de passa¬ gers et de service (douanes, garde-côtes, navire météo, etc...) •In total, the invention relates to a boat combining both qualities of good sea-keeping, speed * and stability of the passenger compartment, particularly suitable for pleasure boats, passenger transport and service (customs, coast guard, weather ship, etc ...) •
On a déjà proposé, comme décrit dans le brevet des Etats Unis d'Amérique n° 2 119 775 de réunir entre elles deux coques de bateaux par une poutre transversale par rapport à laquelle les coques peuvent pivoter et capable de supporter une plate-forme de charge. Toute-It has already been proposed, as described in the patent of the United States of America No. 2,119,775 to join together two hulls of boats by a transverse beam with respect to which the hulls can pivot and capable of supporting a platform of charge. Any-
OMPI fois, dans ce cas, il est prévu entre les deux coques, à l'avant et à l'arrière de cette poutre, des liaisons reliées par ailleurs à la plate-forme, l'ensemble for¬ mant un système complexe et dont les éléments peuvent difficilement admettre les efforts engendrés lors du déplacement en mer d'un tel engin. L'invention apporte une solution simple et efficace au problème posé par l'utilisation d'un système différentiel.WIPO times, in this case, there are provided between the two shells, at the front and at the rear of this beam, connections connected moreover to the platform, the assembly forming a complex system and the elements can hardly accept the forces generated during the displacement at sea of such a machine. The invention provides a simple and effective solution to the problem posed by the use of a differential system.
L'invention est matérialisée en conséquence dan un catamaran comportant deux flotteurs allongés reliés entre eux par un système de poutre portant un habitacl ce système de poutre étant relié à chaque flotteur par une articulation transversale orientée perpendiculaire ment à 1' xe longitudinal de ces flotteurs, caractéris en ce que des moyens constituant un différentiel sont prévus entre ce système de poutre et chaque flotteur afin de maintenir le plan axial de symétrie du système de poutre dans une position moyenne par rapport aux flotteurs. Suivant un mode de réalisation possible, le système différentiel est de type hydraulique et com¬ prend chaque fois au moins un vérin interposé entre un extrémité de la poutre et le flotteur conjugué à cette extrémité, les deux vérins ou jeux de vérins prévus au deux extrémités communiquant entre eux pour maintenir plan axial de symétrie du système de poutre dans une position moyenne par rapport aux flotteurs. Le résulta désiré peut être obtenu notamment en prévoyant, entre le système de poutre et les flotteurs, des vérins à double effet dont les chambres correspondantes sont reliées ensemble.The invention is therefore embodied in a catamaran comprising two elongated floats connected together by a beam system carrying a habitacl this beam system being connected to each float by a transverse articulation oriented perpendicular to the longitudinal axis of these floats, characterized in that means constituting a differential are provided between this beam system and each float in order to maintain the axial plane of symmetry of the beam system in an average position relative to the floats. According to one possible embodiment, the differential system is of the hydraulic type and each time takes up at least one jack interposed between one end of the beam and the float conjugated at this end, the two jacks or sets of jacks provided at the two ends. communicating with each other to maintain the axial plane of symmetry of the beam system in an average position relative to the floats. The desired result can be obtained in particular by providing, between the beam system and the floats, double-acting cylinders whose corresponding chambers are connected together.
Suivant un autre mode de réalisation possible, le système différentiel est de type mécanique et il es prévu entre les extrémités du système de poutre et cha que flotteur un ou plusieurs leviers, les extrémités d ces leviers attaquant le système de poutre étant relié entre elles, par exemple par un palonnier, de manière à réaliser la compensation requise pour le maintien du plan axial de symétrie du système de poutre dans la position moyenne précitée.According to another possible embodiment, the differential system is of mechanical type and it is provided between the ends of the beam system and each float one or more levers, the ends of these levers attacking the beam system being connected together, for example by a spreader, so to achieve the compensation required for maintaining the axial plane of symmetry of the beam system in the aforementioned average position.
Suivant une autre particularité de l'invention, le système différentiel prévu entre le système de pou¬ tre et les flotteurs est asservi à un gyroscope, afin que le plan axial médian du système de poutre soit maintenu dans une position verticale. Dans le cas d'un système différentiel hydraulique, le résultat désiré peut être obtenu en reliant les chambres des vérins à un dispositif formant vanne et à une source de liquide, et en asservissant ce dispositif formant vanne et (ou) la source de liquide au gyroscope. Dans le cas d'un système différentiel mécanique, ce résultat peut être obtenu en prévoyant dans le système de leviers, notam¬ ment dans le palonnier de liaison associé au système de poutre, un dispositif de réglage de longueur qui est asservi à un gyroscope.According to another feature of the invention, the differential system provided between the beam system and the floats is controlled by a gyroscope, so that the median axial plane of the beam system is kept in a vertical position. In the case of a hydraulic differential system, the desired result can be obtained by connecting the chambers of the jacks to a valve device and to a source of liquid, and by controlling this valve device and / or the source of liquid to gyroscope. In the case of a mechanical differential system, this result can be obtained by providing in the lever system, in particular in the connecting beam associated with the beam system, a length adjusting device which is slaved to a gyroscope.
Suivant une autre particularité encore de l'in- vention, l'habitacle qui forme le corps utile du bateau est monté de façon articulée sur le système de poutre de liaison, au milieu de ce système, autour d'un axe horizontal dans le plan axial du bateau, des moyens de commande de position étant prévus entre cet habitacle et ce système de poutre pour maintenir cet habitacle sensiblement dans une position verticale, quelle que soit la position d'inclinaison transversale du bateau et par suite du système de poutre. Suivant un mode de réalisation paraissant judicieux, ces moyens peuvent être asservis à un système gyroscopique. On peut pré¬ voir par exemple, entre l'habitacle et le système de poutre, un ou plusieurs vérins reliés à un système de vanne et à une source de fluide, le système de vanne pouvant alors être asservi à un système gyroscopique. Suivant une disposition judicieuse, l'habitacle est monté sur le système de poutre dans une position telle que son centre de gravité se trouve sensiblement à l'aplomb dudit système de poutre» Ainsi, les efforts devant être fournis par les moyens précités sont relat vement faibles. Si ce centre de gravité de l'habitacle se trouve également à l'aplomb de l'axe d'articulation de cet habitacle sur le système de poutre, un effort réduit doit également être fourni par les moyens notam ment par le ou les vérins, servant à maintenir 1'habi¬ tacle dans une position transversale horizontale.According to yet another feature of the invention, the cockpit which forms the useful body of the boat is mounted in an articulated manner on the connecting beam system, in the middle of this system, around a horizontal axis in the plane axial of the boat, position control means being provided between this cockpit and this beam system to maintain this cockpit substantially in a vertical position, whatever the transverse tilting position of the boat and therefore the beam system. According to an embodiment which seems judicious, these means can be controlled by a gyroscopic system. One can see, for example, between the passenger compartment and the beam system, one or more jacks connected to a valve system and to a source of fluid, the valve system then being able to be controlled by a gyroscopic system. According to a judicious arrangement, the passenger compartment is mounted on the beam system in a position such that its center of gravity is substantially perpendicular to said beam system ”Thus, the forces to be provided by the aforementioned means are relatively low. If this center of gravity of the passenger compartment is also plumb with the articulation axis of this passenger compartment on the beam system, a reduced force must also be provided by the means notably by the jack (s), serving to hold the tackle in a horizontal transverse position.
De cette manière, la position de l'habitacle es contrôlée longitudinalement et latéralement, et il res horizontal sans nécessiter de grande dépense d'énergie, quels que soient les mouvements de la mer.In this way, the position of the passenger compartment is controlled longitudinally and laterally, and it remains horizontal without requiring a great expenditure of energy, whatever the movements of the sea.
Suivant une autre particularité encore, chaque flotteur est constitué par un fuseau de forme allongée, muni à son extrémité avant d'une partie relevée en for de proue. Chaque fuseau porte également, vers son extr mité arrière, une hélice et un gouvernail.According to yet another particularity, each float is constituted by a spindle of elongated shape, provided at its front end with a portion raised in the bow. Each time zone also carries, towards its rear end, a propeller and a rudder.
La description qui va suivre, faite en regard de dessins annexés, donnés à titre non limitatif, permett de mieux comprendre l'invention.The description which follows, given with reference to the appended drawings, given without limitation, allows a better understanding of the invention.

La Fig. 4 est une vue schématique d'extrémité montrant le système de commande latéral prévu ppur l'habitacle. La Fig. 5 est une vue de détail indiquant sché- matiquement le mode de liaison prévu entre les vérins d'un différentiel de type hydraulique.Fig. 4 is a schematic end view showing the lateral control system provided for the passenger compartment. Fig. 5 is a detailed view schematically indicating the mode of connection provided between the jacks of a hydraulic type differential.
Sur les dessins, on a désigné par les références 1 et 2 les éléments de flottaison du bateau, qui sont constitués par deux longs fuseaux relevés à l'avant en forme de proue comme indiqué en 3. Ces fuseaux, de grande longueur, ont une forme effilée afin de fournir d'une part, du fait de leur longueur accrue, un meil¬ leur chevauchement des vagues et, d'autre part, une plus grande vitesse de propulsion. Chaque fuseau est équipé à son extrémité arrière d'une hélice 4 et d'un gouvernail 5. La disposition des organes d'entraînement des hélices et de commande du gouvernail n'a pas été représentée sur les dessins. La détermination de cette disposition est à la portée .de l'homme de l'art, qui pourra faire une application directe des principes techniques connus dans- ce domaine pour la propulsion et la direction des bateaux existants.In the drawings, references 1 and 2 have designated the flotation elements of the boat, which are constituted by two long spindles raised at the bow-shaped front as indicated in 3. These spindles, of great length, have a tapered shape to provide on the one hand, because of their increased length, a better overlap of the waves and, on the other hand, a higher propulsion speed. Each spindle is equipped at its rear end with a propeller 4 and a rudder 5. The arrangement of the propeller drive and rudder control members has not been shown in the drawings. The determination of this provision is within the reach of those skilled in the art, who can make a direct application of the technical principles known in this field for the propulsion and steering of existing boats.
Il est prévu suivant l'invention, entre les deux fuseaux 1, 2, une poutre transversale désignée par la référence 6, qui est montée par ces extrémités au moyen d'axes 7 dans des paliers 8 portés par les fuseaux. Les axes 7 prévus aux extrémités de la poutre 6 sont ali¬ gnés entre eux, et ils sont orientés perpendiculaire¬ ment au plan longitudinal de symétrie du bateau. Ces axes 7 ont, comme visible sur le dessin, une longueur suffisante pour maintenir directionnelle ent les fu¬ seaux 1, 2 parallèles à l'axe longitudinal du bateau. Ils permettent en même temps le débattement de ces fu¬ seaux dans deux plans verticaux qui sont parallèles au plan axial du bateau. Si l'on se reporte tout d'abord au mode de réalisation représenté sur les Fig. 1 et 2, on voit qu'il est prévu, entre chaque extrémité de la poutre 6 et les fuseaux 1, 2 correspondants, chaque fois un vérin hydraulique à double effet 9 qui est relié à articulation par son corps en 10 à l'extrémité cor- respondante de la poutre et par l'extrémité de sa tige de piston en 11 au fuseau 1, 2 conjugué.According to the invention, there is provided between the two spindles 1, 2, a transverse beam designated by the reference 6, which is mounted by these ends by means of pins 7 in bearings 8 carried by the spindles. The axes 7 provided at the ends of the beam 6 are aligned with one another, and they are oriented perpendicular to the longitudinal plane of symmetry of the boat. These axes 7 have, as visible in the drawing, a sufficient length to maintain directional ent fu¬ buckets 1, 2 parallel to the longitudinal axis of the boat. They allow at the same time the movement of these fu¬ buckets in two vertical planes which are parallel to the axial plane of the boat. If we refer first of all to the embodiment shown in FIGS. 1 and 2, we see that there is provided, between each end of the beam 6 and the spindles 1, 2 corresponding, each time a double-acting hydraulic cylinder 9 which is connected to articulation by its body at 10 at the end corresponding to the beam and by the end of its piston rod at 11 to the spindle 1, 2 conjugate.
Suivant l'invention, ces deux vérins sont reliés entre eux de la manière représentée schématiquement sur la Fig. 5. Ainsi, des conduits 12 et 13 relient ense - ble les chambres correspondantes des vérins. On conçoit que, de cette manière, si l'un des fuseaux 1, 2 tend à subir un débattement dans le plan vertical autour de l'axe 7 conjugué, il va se produire, du fait de la communication établie entre les vérins, un débattement égal et de sens opposé de l'autre fuseau, de façon à tendre à maintenir le plan axial de symétrie de la poutre 6, qui est orthogonal au plan axial du bateau, dans une position moyenne- par rapport à ces fuseaux.According to the invention, these two jacks are interconnected in the manner shown diagrammatically in FIG. 5. Thus, conduits 12 and 13 connect together the corresponding chambers of the jacks. It is understood that, in this way, if one of the time zones 1, 2 tends to undergo a deflection in the vertical plane around the axis 7 conjugate, it will occur, due to the communication established between the jacks, an equal and opposite movement of the other spindle, so as to tend to maintain the axial plane of symmetry of the beam 6, which is orthogonal to the axial plane of the boat, in an average position relative to these spindles.
On a représenté également sur la Fig. 5 des con duits 14 et 15 qui peuvent être reliés à un système de vanne associé à une source de liquide. On conçoit qu'e asservissant le système -de vanne alors prévu à un gy¬ roscope, il est possible de commander l'alimentation d vérins de manière à maintenir constamment la poutre 6 dans une position telle que son plan de symétrie demeu re vertical. On a montré sur la Fig. 3 un système de compen¬ sation de type mécanique. Dans ce cas, il est prévu, vers chaque extrémité de la poutre 6, des leviers de renvoi en équerre 16 montés à pivotement sur cette pou tre autour d'axes normalement verticaux 17. Un bras de chaque levier est attaqué par une barre 18, qui est reliée à ce levier 16 par une extrémité au moyen d'une articulation 19, tandis que l'autre extrémité de la barre 18 est reliée de façon articulée en 20 au fuseau correspondant 1, 2. Les autres bras des deux leviers d renvoi 16 sont reliés entre eux par un palonnier 21.Also shown in FIG. 5 of lines 14 and 15 which can be connected to a valve system associated with a source of liquid. It will be appreciated that by slaving the valve system then provided to a gy¬ roscope, it is possible to control the supply of cylinders so as to constantly maintain the beam 6 in a position such that its plane of symmetry remains vertical. We have shown in FIG. 3 a mechanical type compensation system. In this case, provision is made, towards each end of the beam 6, for angled return levers 16 mounted to pivot on this beam around normally vertical axes 17. One arm of each lever is attacked by a bar 18, which is connected to this lever 16 by one end by means of a hinge 19, while the other end of the bar 18 is hingedly connected in 20 to the corresponding spindle 1, 2. The other arms of the two return levers 16 are interconnected by a lifting beam 21.
Le mode d'action de ce système différentiel méc nique se comprend aisément. Dans ce cas encore, lors d débattement dans un sens d'un fuseau dans le plan vert cal, il se produit un pivotement du levier 16 correspo dant autour de son axe 17, et ce déplacement est trans mis par le palonnier 21 à l'autre levier 16, et par l'autre barre 18 à l'autre fuseau, qui ainsi subit un débattement de même amplitude et de sens opposé.The mode of action of this mechanical differential system is easily understood. In this case also, during movement in one direction of a spindle in the green plane cal, there is a pivoting of the lever 16 corresponding around its axis 17, and this movement is transmitted by the spreader 21 to the another lever 16, and by the other bar 18 to the other spindle, which thus undergoes a movement of the same amplitude and in the opposite direction.
Dans ce cas encore, on peut combiner au palonni 21 par exemple un dispositif de réglage de longueur asservi à un gyroscope, de façon à faire varier la lon gueur de ce palonnier et ainsi les positions relatives des fuseaux par rapport à la poutre 6, afin de mainte¬ nir le plan longitudinal médian de cette poutre dans une position verticale»In this case also, it is possible to combine with the palonni 21 for example a length adjusting device controlled by a gyroscope, so as to vary the length of this lifter and thus the relative positions spindles with respect to the beam 6, in order to maintain the median longitudinal plane of this beam in a vertical position "
Le catamaran suivant l'invention comprend égale- ment un habitacle qui forme son corps utile et qui est représenté schématiquement en 22 sur les dessins»The catamaran according to the invention also comprises a cockpit which forms its useful body and which is shown diagrammatically at 22 in the drawings.
Suivant l'invention, cet habitacle est monté sur la poutre transversale 6 au milieu de la longueur de cette poutre, c'est-à-dire dans le plan longitudinal médian du bateau, au moyen d'un axe 23 orienté selon ce plan longitudinal médian du bateau et tourillonné dans des paliers convenables de l'habitacle et de la poutre. Cet axe est orienté perpendiculairement au plan axial médian de la poutre, c'est-à-dire qu'il occupe normale- ment une position horizontale.According to the invention, this passenger compartment is mounted on the transverse beam 6 in the middle of the length of this beam, that is to say in the median longitudinal plane of the boat, by means of an axis 23 oriented along this longitudinal plane. median of the boat and journalled in suitable landings of the cockpit and the beam. This axis is oriented perpendicular to the median axial plane of the beam, that is to say that it normally occupies a horizontal position.
Dans le cas du mode de réalisation représenté et comme visible en particulier sur la Fig. 4, il est pré¬ vu, entre un palier 24 prévu vers une extrémité de la poutre 6 et un- alier 25 prévu sur l'habitacle, un vérin 26 qui est relié à un système de vanne (non repré¬ senté) asservi à un gyroscope, de manière à maintenir cet habitacle dans une position verticale quelle que soit l'inclinaison transversale de la poutre 6.In the case of the embodiment shown and as visible in particular in FIG. 4, it is pre¬ seen, between a bearing 24 provided towards one end of the beam 6 and un- alier 25 provided on the passenger compartment, a cylinder 26 which is connected to a valve system (not shown) slaved to a gyroscope, so as to maintain this passenger compartment in a vertical position whatever the transverse inclination of the beam 6.
L'habitacle est disposé par rapport à la poutre 6 de telle sorte que son centre de gravité se trouve à l'aplomb de cette poutre»The passenger compartment is placed in relation to the beam 6 so that its center of gravity is directly above this beam ”
On comprend ainsi, à la lecture de la descrip¬ tion qui précède, que l'on obtient un ensemble articulé dans lequel les fuseaux peuvent se débattre indépendam- ment suivant l'état de la mer,maintenus par les axes de grande longueur dans deux plans parallèles au plan lon¬ gitudinal axial du bateau. Le système différentiel maintient la poutre supportant l'habitacle dans une position moyenne par rapport aux deux fuseaux et il n'y a que de très faibles efforts dans les liaisons.It is thus understood, on reading the foregoing description, that an articulated assembly is obtained in which the spindles can be struggled independently according to the state of the sea, maintained by the axes of great length in two planes parallel to the longitudinal axial plane of the boat. The differential system maintains the beam supporting the passenger compartment in an average position with respect to the two spindles and there are only very small forces in the connections.
Par ailleurs, la combinaison de moyens décrite permet de contrôler longitudinalement et transversale-Furthermore, the combination of means described makes it possible to control longitudinally and transverse-
OMPI " ment la position de l'habitacle de telle sorte que, quels que soient les mouvements de la mer, cet habitac demeure horizontal. Il en résulte ainsi un confort acc pour les occupants du bateau. Du fait du montage utilisé, ce résultat est at- tient en outre avec une faible dépense d'énergie, puis que la position du centre de gravité de l'habitacle es à l'aplomb de la poutre transversale et du fait du montage articulé de l'habitacle au centre de la poutre, également à l'aplomb de son centre de gravité, pour la stabilisation transversale.WIPO " the position of the passenger compartment so that, whatever the movements of the sea, this passenger compartment remains horizontal. This results in comfort for the occupants of the boat. Due to the mounting used, this result is also achieved with a low energy expenditure, since the position of the center of gravity of the passenger compartment is level with the transverse beam and due to the articulated mounting of the passenger compartment in the center of the beam, also in line with its center of gravity, for transverse stabilization.
L'utilisation de fuseaux de grande longueur libres de leurs positions relatives permet également u meilleur chevauchement des vagues, donc une meilleure tenue en mer, propriété qui vient s'ajouter à la bonne tenue générale en soi déjà connue des bateaux du type catamaran. Il convient encore d'ajouter que, pour une puissance donnée, la vitesse d'un bateau de ce type es accrue puisqu'elle dépend, pour un même tonnage et pou une même puissance, de la longueur et de la finesse de la coque, qui est formée dans le cas présent par deux fuseaux longs et effilés.The use of long spindles free of their relative positions also allows better overlapping of the waves, therefore better handling at sea, a property which is added to the good general handling in itself already known for catamaran type boats. It should also be added that, for a given power, the speed of a boat of this type is increased since it depends, for the same tonnage and for the same power, on the length and fineness of the hull, which is formed in this case by two long and tapered spindles.
Des modifications peuvent être apportées aux modes de réalisation décrits, dans le domaine des équi valences techniques, sans s'écarter de l'invention.Modifications can be made to the embodiments described, in the field of technical equivalences, without departing from the invention.
