Abstract

Amphibious fishing-boat having retractable devices. The invention relates to a device enabling a fishing-boat to be trailed (drawn) and moved without it being necessary to use a trailer when travelling on land. This invention makes it possible to render amphibious a fishing-boat designed for this purpose. It is constituted by the creation, while the hull is being moulded, of cavities enabling a set of wheels to be easily installed, the set of wheels having an incorporated suspension possessing a retractable mechanical device on the one hand, as well as a tubular drawbar equipped with a trailing (drawing) device, which can be retracted into the stem at will, enabling any vehicle to be stowed which is equipped with a hitch to a ball whose diameter lies between 0 and 50 mm. A device, operating simultaneously with the retractable mechanism for the set of wheels, blocks off the two lateral openings, thereby maintaining hydrodynamic quality.

Description

 The present invention relates to an amphibious fishing boat device: 3 retractable.

 The device which is the subject of this invention consists of elements which are incarcerated in the fishing shrimp cell and which can be retracted or released at will and which allow either normal navigability, handling, towing or transport of this boat on land.

 Usually they are land or air vehicles that can be equipped or equipped to become amphibious.

 the new invention involving an inventive step and capable of industrial application consists in reversing this state of the art and rendering a marine vehi- cle amphibious so that it can be handled, towed or transported on land without any additional the force necessary for these manipulations.

 The device according to the invention allows the pilot of the boat thus designed to be freer when put out of water and avoid the use of a trailer.

This device is shown on the attached plate
.4 Figure 1 shows the boat seen from the left side, the train running and the trailing bar in the out position, ready to roll on the ground.

 Figure 2 shows the boat seen from the left side, the train rolled and the pull bar in the retracted position, thus retracted into the structure of the boat.

 Figure 3 shows the boat seen from the rear with its rolling train out.

These elements are as follows
(a) A rolling or landing gear (1) consisting of a rigid axle with built-in dampers.

 b) A mechanical device (5) fixed at each end consisting of guide rails, worm gear driven by pinion and angle gear enabling effortless synchronized vertical movement of the entire wheel set.

 This running gear (1) is retractable on demand; he retracts into the hull to take a position of navigation in large boxes (2) arranged under the hull on both sides of the boat and slightly behind the center of gravity of the latter. Traps (3) mounted in side slides, slide on demand to fade in front of the wheel train (1) at the time of its descent. The hatches close to hide the opening of the boxes when used on water.

 Once the wheel train returned (4) the boat resumes a normal appearance for haviguation. (In Figure 2 (10) represents the flotation line).

 For the road position, the entire set of wheels (1) descends under the hull under the influence of mechanical devices (5) actuated in the boat before landing. The hatches (3) will simultaneously give way, so that the boat is ready to roll on land when put out of the water. (In Figure 1 the (11) represents the ground or the pavement).

 The device relating to this undercarriage (1) is made of materials suitable for its marine use.

 The wheels are of the "land vehicle" type, tires, on rims and rolling axles. The support and lifting elements are those which can be found commercially in the design of boat trailers.

A drawbar called drawbar (9) retractable is housed in the bow (12) of the boat. Its design allows it to slide in an articulated sheath and to come in the traction position and to keep locked there by a broaching (7). The other end of the drawbar (9) is pou.xua a trailer attachment system for docking on the standard hitch (ball / 5üj.

The hull is made of polyester laminate with reinforcements (5) to- and mat of glass at the places most stressed by the inherent constraints due to traffic on the road. A sheath embedded in the hull allows the judicious passage of electrical wiring from the front of the boat (for car connection) to the transom (high beam connection, removable plate lighting).

 The boat thus fitted with its drawbar (9) and its rolling train, (X) can indistinctly be provided with an internal or external motor model.

When forming the hull molding, suitable forms allows for the development of reserves (2), caissons and compartments.

Claims (4)

 1) Device incorporated and integrated in the cell of a fishing boat characterized in that it comprises a retractable undercarriage (1), a drawbar or drawbar (5) retractable to make it amphibious.  2) Device according to claim 1 characterized in that the undercarriage (1) and the drawbar (9) are incorporated in the cell of the boat, sealed in the mass of the hull of the boat so that it will withstand the unusual stresses caused by forces or forces inherent in the rolling of the boat when towed on the road by a vehicle.  3) Device according to claim 1 characterized by the installation of a mechanical system for retraction or exit of the wheel train (1) and the drawbar (9).  4) Device according to claim 1 characterized by a method of diposition and development of reserves, housing, boxes and compartments. This method consists in molding the hull of the boat, to mold on appropriate forms, tangent fixing points (8) reserves necessary for the incorporation of the retractable elements of the rolling train and the bar of traction as well as the electrical equipment.
