Abstract

The transport device is fitted to a boat having two articulated half hulls so that the center board (B) becomes the tiller. It is composed of two independent half axles (A) which pivot in a support tube welded to the bottom of the hull, and two ailerons (F). A front wheel support (C) is retractable in the stem. There is a locking system (D) for the half hulls in the open position and an opening and closing system (E).

Description

CONTEXTE.DESCRIPTION. La présente invention concerne un ensemble de dispositifs auto-porté de miseà l'eau et de débarquement adapté aux embarcations légères. CONTEXTE.DESCRIPTION. The present invention relates to a set of self-carrying devices for setting to water and landing suitable for light craft .

Jusqu'à présent,pour mettre un bateauà l'eau plusieurs possibilités s'imposentà l'utilisateur: SOIT la miseà l'eauà l'aide d'une remorque spécialisée tractée par un véhicule suffisamment puissant pour permettre de reculer le long d'une rampe de miseà l'eau construite et entretenue par la collectivité locale. Opération assez délicate qui nécessite souvent de reculer les roues arrières du véhicule jusque dans l'eau. Until now, to put a boat to water several possibilities are required to the user : BE B> putting to water to with the help of a trailer towed by a vehicle that is strong enough to roll back along a ramp. B> to water built and maintained by the local community. This is a delicate operation that often requires moving the rear wheels of the vehicle back into the water.

SOIT La miseà l'eau au moyen d'une grue portuaire qui assure le déplacement du bateau de la remorquejusqu'à l'eau.Les deux équipements précédents sont peu fréquents et ne sont pas forcementà proximité de l'endroit souhaité pour l'utilisation du bateau. EITHER to the water by means of a harbor crane that moves the boat from the trailer to the water.The two previous equipments are infrequent and are not necessarily at near the desired location for the use of the boat.

Le caractère innovant du dispositif inventé réside d'abord dans la réunion sur un même moyen de fonctions dissociables dans leur environnement. The innovative character of the invented device resides first in the meeting on the same means of dissociable functions in their environment.

Le bateau est équipé du dispositif composé de, deux demi essieux de déplacement adaptés et escamotables qui pivotent séparément dans un tube soudé au fond de la coque du bateau. Chacun d'eux est immobilisable dans deux positions possibles au moyen d'un bras de liaison avec la coque Ceci permet de placer les roues soit en position basse pour rouler soit en position haute pour naviguer Le dispositif prévoit d'autre part un essieu avant intégré de débarquement qui permet d'abaisser une roue de l'intérieur de la coque jusqu'à une position de roulement ainsi qu'un sabot de débarquement pour protéger le dispositif au niveau de l'étrave Le dispositif prévoit d'autre part l'utilisation de la dérive en timon de traction pour rouler sur la route mais pour ce faire le bateau auradû être construit en deux parties pivotantes l'une par rapportà l'autre de sorte que la demi-coque avant fasse couvercle sur la demi coque arrière et laisse ainsi libre la dérive maintenueà sa place et qui peut ainsi devenir timon de traction Le fait que le bateau soit en deux parties ne fait l'objet d'aucune revendication par contre le dispositif offreà l'utilisateurun système de blocage des demi-coques en position ouverte constitué de deux coins mobiles en translation verticale par rapportà une demi-coque et agissant sur des anneaux soudés sur l'autre demi-coque ainsi qu'un système d'aideà la fermeture età l'ouverture. Ce dernier est constitué d'un mât pivotantà son pied sur la demi-coque avant, un câble reliant son sommetà l'étrave du bateau et en partie médiane duquel agissent de puissants ressorts fixés sur la demi-coque arrière de façon telle qu'ils agissent pour rendre très faible l'effort musculaire nécessaireà l'ouverture ouà la fermeture quelque soit la position angulaire de la demi-coque avant Enfin un aileron disposé sur chaque bordé du bateau permet de répondre aux7 fonctions suivantes ;garde boue, pare cycliste marche pieds pare battage butée angulaire pour les roues en position haute poignée d'aideà louverture età la fermeture et support pour un mécanisme standard de fermeture de sécurité des demi-coques en position ouvert. The boat is equipped with the device consisting of , two adapted and retractable half-axles of displacement that pivot separately in a tube welded to the bottom of the hull of the boat . Each of them is immobilisable in two possible positions by means of a connecting arm with the hull This makes it possible to place the wheels either in the low position to roll or in the up position to navigate The device further provides an integrated front landing axle which allows to lower a wheel from the inside of the hull to a rolling position and a landing shoe to protect the device at the bow The device further provides the use of the drift in drawbar to roll on the road but to do this the boat will have to be built in two pivoting parts one relative to the other so that the half -before make cover on the back half hull and leave nsi free drift maintained at its place and can thus become traction drawbar The fact that the boat is in two parts is not the subject of any claim against the device offers to the user a system of blocking half-shells in open position consists of two movable wedges in vertical translation relative to a half-shell and acting on welded rings on the other half-shell as well as a help system to the closure and to the opening . consists of a mast pivoting to its foot on the front half-hull, a cable connecting its top to the bow of the boat and in the middle part of which act powerful springs attached to the rear half-shell in such a way that they act to make the muscular effort required at the opening or at the closing, whatever the position angular of the front half-hull Finally a fin available s on each side of the boat to answer the following 7 functions: mudguard, bumper guard feet fender bumper angular stop for wheels in high position help handle to opening and to the closure and support for a standard half-shell safety closure mechanism in the open position .

Les avantages du procédé sont de permettre la miseà l'eau quelque soit l'état de la bergeà l'endroit choisi, indépendamment des problèmes de miseà l'eau sans avoir a se soucier de stationner une remorque ni d'acquérir un véhicule puissant puisque lutilisation du véhicule n'est pas obligatoire. The advantages of the process are to allow the water to be placed whatever the state of the bank to the chosen location, independently of the problems of setting the water without having to worry about parking a trailer or buying a powerful vehicle since the use of the vehicle is not mandatory .
