Description
L'invention concerne un dispositif de sécurité et de stabilité dans la mer en tempête pour embarcations à moteur selon le préambule de la revendication 1.The invention relates to a safety and stability device in stormy seas for motor boats according to the preamble of
Un tel dispositif est connu du document FR-A-1408225 qui concerne une nouvelle forme de bateau (habitacle) de plaisance et de sport qui rend le manque de stabilité sans effets, mais son irrénversabilité est conditionnée par le fait qu'on doit employer exclusivement un moteur à hélice aérienne. Si dans cette réalisation l'inventeur, au lieu de mettre quatre bras fixes à ± 90 degrés entre eux, avait disposé quatre bras pouvant être distanciables entre eux, comme cela figure dans les revendications 1, 2 et 3 de l'invention, et s'il avait developpé les caractéristiques selon la légende (A), (G) et (K), il aurait résolu le problème.Such a device is known from document FR-A-1408225 which relates to a new form of pleasure and sports boat (cockpit) which renders the lack of stability without effect, but its irreversibility is conditioned by the fact that it must be used exclusively an overhead propeller engine. If in this embodiment the inventor, instead of putting four fixed arms at ± 90 degrees between them, had arranged four arms which can be distant from each other, as shown in
Par conséquent, l'habitacle suspendu en l'air ne pourra en aucun cas être immergé et en même temps être irrénversable. Si l'habitacle, avec les bras complètement sortis ou complètement rentrés, immerge dans l'eau un objet quelconque faisant corps unique avec l'habitacle (par exemple: l'hors-bord) les coques après une rotation de ± 45 degrés seront empêchées dans leur rotation par l'hors-bord et le dispositif est donc inutilisable et, par conséquent, l'embarcation devient un catamaran normal.Consequently, the cabin suspended in the air can in no case be submerged and at the same time be irreversible. If the cockpit, with the arms fully extended or fully retracted, immerses in the water any object forming a single body with the cockpit (for example: the outboard) the hulls after a rotation of ± 45 degrees will be prevented in their rotation by the outboard and the device is therefore unusable and, consequently, the boat becomes a normal catamaran.
La présente invention a pour but de parvenir à une complète irrenversabilité dans toutes les directions pour les embarcations à moteur. Cet objectif est atteint par un dispositif selon le préambule de la revendication 1 par les caractéristiques de sa partie caractérisante.The object of the present invention is to achieve complete irreversibility in all directions for motor boats. This objective is achieved by a device according to the preamble of
Le système se compose de coques latérales B qui peuvent être au nombre de deux, trois, quatre ou plus; ces coques sont de formes et de dimensions diverses. Elles peuvent, avec n'importe quel système, tourner autour de l'embarcation centrale I.The system consists of side shells B which can be two, three, four or more; these shells are of various shapes and sizes. They can, with any system, turn around the central boat I.
De bâbord à tribord et vice versa. Lorsque les coques sont immergées, elles appliquent une poussée verticale constante qui soutient l'embarcation.From port to starboard and vice versa. When the hulls are submerged, they apply a constant vertical thrust which supports the boat.
DISPOSITIF A DEUX COQUES LATERALES DOUBLES (dessins 1-4). Si la mer devait entraîner un chavirement, situation qui est peu envisageable en raison de la double poussée, une des coques passerait alors sous la quille et l'autre se retrouverait en hauteur, à côté du pont et en surplomb; cependant, un des deux bras C, en tournant, enclencherait l'extension du piston "G" (poupe et proue) et de surcroît, le bras en surplomb, en tombant, passerait devant un autre mécanisme qui lui fera retourner les pistons G dans leur position initiale. L = L1 (action).DEVICE WITH TWO DOUBLE SIDE SHELLS (drawings 1-4). If the sea were to capsize, a situation which is hardly conceivable due to the double thrust, one of the hulls would then pass under the keel and the other would end up high, next to the deck and overhanging; however, one of the two arms C, by turning, would trigger the extension of the piston "G" (stern and bow) and in addition, the overhanging arm, falling, would pass in front of another mechanism which will cause it to return the pistons G in their initial position. L = L1 (action).
Le dispositif sera pourvu d'un arrêt de course réglable.The device will be provided with an adjustable stroke stop.
La manoeuvre durera 10 à 15 secondes, moment durant lequel il y aura une instabilité.The maneuver will last 10 to 15 seconds, during which time there will be instability.
Dans le dispositif à deux et trois coques, on a prévu un mécanisme qui sera logé à l'intérieur de l'essieu et qui empêchera aux deux tuyaux de l'huile de s'entortiller.In the device with two and three shells, a mechanism has been provided which will be housed inside the axle and which will prevent the two oil pipes from kinking.
Une pompe à huile, ACTIONNEE manuellement, sera installée dans le circuit au cas où la pompe à moteur ne fonctionnerait pas.An oil pump, OPERATED manually, will be installed in the circuit in case the motor pump does not work.
DISPOSITIF A TROIS COQUES DOUBLES: trois bras et trois pistons G1-G2-G3 satisfont L0-L1, de plus, D satisfait K.DEVICE WITH THREE DOUBLE SHELLS: three arms and three pistons G1-G2-G3 satisfy L0-L1, moreover, D satisfies K.
Sur le dessin 7, on peut voir le dispositif en L qui a subit un renversement.In drawing 7, we can see the L-shaped device which has undergone a reversal.
Le piston G1 qui se trouvait en bas est passé à tribord alors que le piston G2, qui était à bâbord, est passé en bas; pour remettre le mécanisme en L, il faudra allonger G2 et simultanément, G1 se raccourcira. Le piston G3 reste immobile. La manoeuvre s'effectuera toujours entre le piston qui se trouvera en bas et celui qui s'y trouvait précédemment.The piston G1 which was at the bottom went to starboard while the piston G2, which was at port, went to the bottom; to put the mechanism back in L, it will be necessary to lengthen G2 and simultaneously, G1 will be shortened. The piston G3 remains stationary. The operation will always be carried out between the piston which will be at the bottom and the one which was there previously.
Si la mer redevient calme (cfr DES. 8), on peut mettre le dispositif en position L0 en allongeant le piston G2 et en raccourcissant G1-G3.If the sea becomes calm again (see DES. 8), the device can be put in position L0 by lengthening the piston G2 and shortening G1-G3.
Pendant ce temps, l'huile des pistons G1-G3 passera dans le piston G2 qui s'allongera.During this time, the oil from the pistons G1-G3 will pass into the piston G2 which will lengthen.
Sur le DESSIN 12, on peut voir une embarcation chargée vue de l'arrière.On DRAWING 12, you can see a loaded boat seen from the back.
DISPOSITIF COMPOSE DE QUATRE COQUES et quatre bras, est en position L (Action), les bras D satisfont K et peuvent être prolongés grâce à quatre pistons hydrauliques ou grâce à quatre crics à crémaillère. L'ouverture des bras à compas peut être effectuée avec n'importe quel système ou, comme sur le dessin, le piston G satisfait L0-L1.DEVICE COMPOSED OF FOUR SHELLS and four arms, is in position L (Action), the arms D satisfy K and can be extended by four hydraulic pistons or by four rack jacks. The opening of the compass arms can be carried out with any system or, as in the drawing, the piston G satisfies L0-L1.
Les deux pistons Z servent à distancer de façon symétrique les deux coques en hauteur; le distanciateur "M", en hauteur, glissera à l'intérieur de son logement. Lorsque le dispositif est placé dans la position désirée, il faut fermer les robinets de l'huile, arrêter la pompe et détacher les tuyaux reliés au mécanisme. Dans cette position, il pourra tourner à volonté et sans aucun problème.The two Z pistons are used to symmetrically distance the two shells in height; the distance meter "M", in height, will slide inside its housing. When the device is placed in the desired position, it is necessary to close the oil taps, stop the pump and detach the pipes connected to the mechanism. In this position, it can rotate at will and without any problem.
La forme des coques latérales peut varier par rapport à celle qui est représentée sur les DES. 10-13.The shape of the side shells can vary from that shown in the DES. 10-13.
DISPOSITIF VU SUR LES DESSINS 14-19, il se compose de quatre coques latérales. La forme des coques peut être modifiée.DEVICE SEEN ON DRAWINGS 14-19, it consists of four side shells. The shape of the shells can be changed.
Il s'agit d'un système simple formé de quatre bras C qui servent de logement aux quatre bras "D", ils peuvent s'allonger par l'intermédiaire des pistons hydrauliques ou de tout autre genre de dispositif, ils peuvent satisfaire "K" de plus, le système est pourvu de quatre tubes "W" qui servent de logement aux bras verticaux "V" qui, eux, satisfont L0-L1 (cfr DES. 16).It is a simple system formed by four arms C which serve as accommodation for the four arms "D", they can be extended by means of hydraulic pistons or any other kind of device, they can satisfy "K "moreover, the system is provided with four tubes" W "which serve as accommodation for the vertical arms" V "which, themselves, satisfy L0-L1 (cf. DES. 16).
Les bras verticaux "V" peuvent être allongés via un système identique à celui des bras "D".The vertical arms "V" can be extended using a system identical to that of the arms "D".
Ce dispositif peut, comme on le remarque si on se réfère au DES. 16, s'adapter aux petites et aux grandes embarcations. Les coques en pointillés représentent le dispositif dans la position L0. Quand le mécanisme est placé dans la position souhaitée, il faut fermer les robinets de l'huile, arrêter la pompe et détacher les tuyaux reliés au système.This device can, as we can see if we refer to the DES. 16, adapt to small and large boats. The dotted shells represent the device in the L0 position. When the mechanism is placed in the desired position, it is necessary to close the oil taps, stop the pump and detach the pipes connected to the system.
Dans cette position, il peut tourner chaque fois que la mer tentera de faire chavirer l'embarcation.In this position, it can turn whenever the sea tries to capsize the boat.
