DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a watercraft that can enjoy the gliding on the water surface and the glide flying away from the water by its own power.

[0002]

2. Description of the Related Art Heretofore, there has not been found any thing relating to a surface watercraft capable of enjoying gliding on the water surface and glide flying away from the water. Although no prior art related to this is found, the following inventions are cited as prior art documents which are somewhat related. That is, JP-A-5-8
No. 797 "Towing type water gliding play equipment" is based on the fact that the water gliding equipment towed by a power boat glides on the water when the towing speed is low, and rises and glide when the towing speed increases. It is in.

[0003]

The water gliding glide play equipment having the above-described structure has a structure that allows the user to enjoy gliding on the water surface and gliding away from the water surface. However, this playground equipment glides or glides while being towed by the power boat, and does not enter a state where the pilot himself controls and enjoys. Therefore, problems such as lack of interest or pleasure through maneuvering and the like, and the fact that it is included only in the category of play and contributes to the improvement of maneuvering skills, are very few.

[0004] Therefore, the present invention can enjoy the gliding on the water surface and the glide flying away from the water by completely maneuvering by itself without being towed by another power boat or the like. A watercraft is provided for the purpose of, for example, being able to enjoy the pleasure or real pleasure of a vehicle, or contributing to an improvement in maneuvering skills.

[0005]

In order to achieve the above object, the present invention employs the following configuration.

That is, a watercraft according to the present invention has an airframe having at least a half-cut main wing, a wing portion including horizontal wings and vertical wings, a propeller and an engine, and supports the airframe on the water surface, and And a boat part provided at appropriate intervals, and a floating wing front support bracket provided on the boat part that provides lift to the body and the boat part provided at an interval formed by the body and the boat part. A floating wing, which is pivotally mounted, and an operating rod provided on an operation seat of an airframe that controls an elevation angle of the floating wing, and a floating wing vertical device provided on the boat unit for vertically moving a rear portion of the floating wing. Yes,
The wing portion and the levitating wings glide at a height slightly apart from the water surface due to the upwardly inclined state, and the wing portion and the levitating wings can slide on the water surface by the substantially horizontal state and the rotation of the propeller. is there.

[0007]

Next, a description will be given of gliding on a water surface of a watercraft according to the present invention and gliding on a water surface.

First, when gliding, the engine of the fuselage is driven to rotate the propeller of the fuselage, so that a propulsive force is given to the fuselage and the boat to move forward, so that the water glides. The boat can glide on the water surface while being stably supported by the boat section. At this time, the levitating wing is maintained in a substantially horizontal state (the same horizontal plane as the water surface), and no special operation is performed on the wing portion. Therefore, as described above, lift (the boat is buoyant, but collectively referred to as lift) is not generated on the body and the boat in principle, and slides on the water surface as described above.

On the other hand, for the purpose of glide, the lifting wing and the floating wing of the wing portion are adjusted from the above-mentioned state by operating the operating rod or the operating handle (not shown) in the operating room. As in the case of the levitating wing in FIG. 1, the aircraft body and the boat section are given a lift force by being in a forwardly inclined state. At this time, since the main wing has a width that substantially spans a pair of float portions (in the present invention, it is half cut), the boat portion just leaves the water surface, and only slightly floats, and the boat portion and the waterboat Glide without water resistance. When the engine is stopped, the watercraft floats on the water surface via the boat.

[0010]

An embodiment of the present invention will be described below with reference to the drawings. The watercraft of the present invention comprises an airframe 1 and a boat 2
, A propeller 3 and a wing section 4 provided on the body 1
And a levitation wing 5 provided at a distance formed between the body 1 and the boat unit 2 (above the boat unit 2) as main components.

The fuselage 1 is formed into an outer shape that reduces air resistance like a normal aircraft, and has a cockpit,
An operating rod (including an operating handle and other operating tools) or an engine (not shown) is provided. The boat section 2 is composed of a pair of left and right boat-shaped floats 21 so that the water surface boat can stably float or glide on the water surface .
Further , a front body fixing leg 22 and a rear body fixing leg 23 are provided on the float 21 to support the body 1 and form a space between the float 21 and the boat 2. The propeller 3 is rotated by the driving force of an engine provided in the body 1,
The propeller 3 is rotated through this rotation, and an air flow is generated from the front to the rear of the propeller 3 to cause the watercraft to move forward by the reaction.

The engine is provided at the front or rear of the body 1, and the propeller 3 is provided at the front or rear of the body 1 correspondingly. 1 shows a case with a front engine, and FIG. 3 shows a case with a rear engine. The wing section 4 is provided at a front portion outside the fuselage 1 to provide lift to the fuselage. The wing section 4 is a half-cut main wing 41 and an auxiliary wing 42 provided at the rear portion outside the fuselage 1 to provide lift to the fuselage 1.
And a vertical wing 45 and a rudder 46 which are also provided at the rear and change directions.

Although the water leveling boat of the present invention has a shape like an airplane, it does not aim to fly high in the air.
Even if the water comes off, the vehicle will run at a height of 3 m or less in principle as the surface of the water passes, so the half-cut main wing 41 is not as long as a normal airplane, and as shown in the plan view of FIG. Is a width that almost straddles. This auxiliary wing 4
2. The adjustment of the angles of the lifting blades 44 and the rudder 46 is performed by operation from the cockpit.

The levitation wings 5 are provided at intervals formed by the fuselage 1 and the boat portion 2, and move up and down within the interval.
It works to assist the lift generated by the wings 4.
That is, the floating wings 5 are attached using a pair of floating wing front support brackets 51 provided at the front of the pair of left and right floats 21 and a pair of floating wing lifting and lowering devices 52 provided at the rear.
Therefore, a motor 53 is provided near the levitating blade raising / lowering device 52, and the motor 53 is operated from the cockpit to raise and lower the levitating blade 5 with the front part of the levitating blade 5 as a fulcrum.
The angle of elevation can be adjusted. In addition, although the screw mechanism is adopted in the illustrated example, the floating wing lifting and lowering apparatus 52 may be other cylinder mechanisms, link mechanisms, and other elevating mechanisms. In short, the floating wing 5 swings with one side as a fulcrum in principle. Any configuration is possible. In addition, one of the floating wings 5 does not necessarily need to be a fulcrum, and a structure in which both oscillate is possible. Further, a structure in which the floating wing lifting and lowering device 52 is provided at the center and both ends thereof are supported by guide poles is also possible. Also, an example of the floating wing 5 will be described.
FIG. 6 shows a case where one (single) levitation wing 5 is installed,
FIG. 7 shows a case where two (plural) floating wings 5 are installed. However, although not shown, a large number of floating wings 5 or a combination of floating wings 5 may be installed. 4 and 5
Shows the case where the two floating wings 5 are installed, the case with the front engine and the case with the rear engine.

As described above, by starting the engine and rotating the propeller 3, the watercraft can glide on the water surface. Further, by adjusting the wings 4 and the levitation wings 5, the watercraft can lift off and receive water,
Glidable without water resistance. Thereby, gliding and gliding on water can be enjoyed. However, the surface watercraft is not intended to fly high in the sky, and shall fly at a height of 3 m or less from the surface of the water even when it leaves the water. The height is adjusted mainly by adjusting the elevation angle of the floating wing 5. In addition, when flying at a height exceeding 3 m, since the flight requires special qualification as an airplane, the flight is performed at a height of 3 m or less from the water surface as described above.
