Description

L'invention a pour objet une embarcation dont la coque comporte un attelage incorporé. The subject of the invention is a boat, the hull of which includes an incorporated coupling.

Sortir ou mettre à l'eau une embarcation est toujours une opération plus ou moins compliquée et fastidieuse. Getting out or putting a boat in the water is always a more or less complicated and tedious operation.

Il existe un très grand nombre de types de remorques avec des dispositifs de manutention les plus divers et plus ou moins compliqués. There are a very large number of types of trailers with the most diverse and more or less complicated handling devices.

Presque tous ces dispositifs comportent un treuil et des rouleaux pour faire glisser le bateau à l'eau ou sur la remorque. Certains prévoient un châssis articulé. D'autres prévoient une deuxième remorque sur la première, cette deuxième remorque étant conçue pour pénétrer dans l'eau où le bateau est complètement libéré.Almost all of these devices include a winch and rollers for sliding the boat in the water or on the trailer. Some provide for an articulated chassis. Others provide a second trailer on the first, this second trailer being designed to enter the water where the boat is completely released.

Ces différents dispositifs présentent de nombreux inconvénients parmi lesquels on peut citer la complexité de la manoeuvre, la complexité mécanique et le risque d'avaries que cela comporte, le temps de manoeuvre relativement long qui encombre la cale de mise à l'eau au détriment des autres usagers, le coût élevé d'une remorque qui s'ajoute au prix du bateau et l'encombrement d'une remorque qu'il est difficile et onéreux de garer à proximité du port en plus du véhicule qui la tracte. These different devices have numerous drawbacks, among which we can cite the complexity of the maneuver, the mechanical complexity and the risk of damage that this entails, the relatively long maneuver time which encumbers the slipway at the expense of other users, the high cost of a trailer which is added to the price of the boat and the size of a trailer which is difficult and expensive to park near the port in addition to the vehicle towing it.

Ces nombreux inconvénients ont fait apparaître des embarcations dont la coque comporte des roues escamotables et éventuellement un attelage. These numerous drawbacks have made boats appear whose hull has retractable wheels and possibly a hitch.

On peut ainsi citer les brevets suivants pour définir l'état de la technique : DT-A- 1.816.072, US-A- 3.689.950, US-A-2.851.705. Ces brevets décrivent des mécanismes, pour escamoter les roues dans la coque de l'embarcation, qui sont irréalisables ne serait-ce que par la présence de l'eau et à fortiori de l'eau de mer. Ces mécanismes ne peuvent pas fonctionner, ils font intervenir trop de pièces mécaniques, trop de ressorts, de commandes à vis, etc. ; toutes ces pièces se bloquent inéluctablement. We can thus cite the following patents to define the state of the art: DT-A- 1,816,072, US-A- 3,689,950, US-A-2,851,705. These patents describe mechanisms for retracting the wheels in the hull of the boat, which are impracticable if only by the presence of water and a fortiori sea water. These mechanisms cannot function, they involve too many mechanical parts, too many springs, screw controls, etc. ; all these parts are inevitably blocked.

L'invention tend donc à résoudre tous ces inconvenients. The invention therefore tends to resolve all these drawbacks.

De même, 1' attelage est soit intégré dans la coque de l'embarcation, il est donc toujours à poste, soit l'attelage est amovible. Similarly, the hitch is either integrated into the hull of the boat, so it is always stationary, or the hitch is removable.

L'attelage est assuré par un axe se terminant à une extrémité par un crochet de remorquage et à l'autre extrémité par une plaque de renfort intégrée dans la coque. Si la coque est en plastique, la plaque de renfort est noyée dans le polystyrène. The coupling is ensured by an axis ending at one end by a towing hook and at the other end by a reinforcement plate integrated in the hull. If the shell is made of plastic, the reinforcement plate is embedded in the polystyrene.

Des moyens faisant office de ressorts sont disposés au niveau de l'attelage pour amortir les chocs. Means acting as springs are arranged at the level of the coupling to absorb shocks.

Lesdits moyens faisant office de ressorts sont un joint caoutchouc et un ressort. L'un et l'autre sont montés solidaires de l'axe de l'attelage et d'une pièce cylindrique dans laquelle ledit axe de l'attelage coulisse. Said means acting as springs are a rubber seal and a spring. Both are mounted integral with the axis of the hitch and a cylindrical part in which said axis of the hitch slides.

Les dessins ci-joints donnés à titre d'exemple indicatif ét non limitatif permettront aisément de comprendre l'invention. Ils représentent un mode de réalisation préféré selon l'invention. The attached drawings given by way of indicative and non-limiting example will easily make it possible to understand the invention. They represent a preferred embodiment according to the invention.

La figure 1 est une vue en coupe de l'embarcation au niveau de la proue, mettant en évidence l'attelage intégré dans la coque. Figure 1 is a sectional view of the boat at the bow, highlighting the hitch integrated in the hull.

La figure 2 est une vue en coupe de l'embarcation au niveau de la proue, mettant en évidence la réaction de attelage en cas de choc, comme représenté selon la flèche F2. Figure 2 is a sectional view of the boat at the bow, highlighting the coupling reaction in the event of an impact, as shown in arrow F2.

Au niveau de la proue 6, un attelage 7 est intégré dans la coque 1. At the bow 6, a hitch 7 is integrated in the hull 1.

Cet attelage 7 est constitué d'un axe 21 terminé à une extrémité par un crochet de remorquage 22 qui-permet l'accrochage connu à une boule 23 solidaire de l'engin motorisé (non représenté sur les figures). This coupling 7 consists of an axis 21 terminated at one end by a towing hook 22 which allows the known attachment to a ball 23 secured to the motorized vehicle (not shown in the figures).

L'autre extrémité passe dans une tige cylindrique 24, qui est solidaire d'une plaque de renfort 25 fixée à la coque 1. Dans le cas où la coque 1 est en plastique, la plaque de renfort et la tige cylindrique 24 sont noyées dans le plastique polyester. A l'intérieur de la pièce, cylindrique 24 et autour de l'axe 21, est disposé un ressort à boudin 26. The other end passes through a cylindrical rod 24, which is integral with a reinforcement plate 25 fixed to the shell 1. In the case where the shell 1 is made of plastic, the reinforcement plate and the cylindrical rod 24 are embedded in polyester plastic. Inside the part, cylindrical 24 and around the axis 21, is disposed a coil spring 26.

Un joint en caoutchouc 27 est disposé entre la tige cylindrique 24 et l'extrémité cylindrique du crochet de remorquage 22. Des moyens 26 et 27 font office d'amortisseur. Ils amortissent les chocs qui peuvent se produire, comme indiqué dans le sens de la flèche F.A rubber seal 27 is disposed between the cylindrical rod 24 and the cylindrical end of the tow hook 22. Means 26 and 27 act as shock absorbers. They absorb any shocks that may occur, as shown in the direction of the arrow F.

Dans le cas d'un choc, comme indiqué par la flèche F, l'axe 21 coulisse dans la tige cylindrique 24, le ressort 26 absorbe le choc en étant compressé, il est maintenu dans ladite pièce cylindrique 24 par des moyens faisant office de butée non représentés sur les figures. In the case of a shock, as indicated by the arrow F, the axis 21 slides in the cylindrical rod 24, the spring 26 absorbs the shock by being compressed, it is held in said cylindrical part 24 by means acting as stop not shown in the figures.

Comme on peut le constater, l'embarcation selon l'invention est d'un maniement très simple. As can be seen, the boat according to the invention is very simple to handle.

Selon un autre mode de réalisation non représenté sur les figures, la tige de traction, par une extrémité 22 faisant office de crochet de remorquage vient s'accrocher à la bouée de remorquage 23 et l'autre extrémité vient se visser directement dans une pièce cylindrique filetée borgne et noyée dans l'étrave.  According to another embodiment not shown in the figures, the traction rod, by one end 22 acting as a towing hook comes to hang on the towing buoy 23 and the other end is screwed directly into a cylindrical part blind threaded and embedded in the bow.
