[0001]

The present invention relates to a needle keeping property, a turning property,
The present invention relates to an airboat that is excellent in maneuverability such as wave surveillance and acceleration, and is excellent in portability and riding comfort.

[0002]

2. Description of the Related Art Conventionally used air boats are known in which a bottom floor is made of a plate material such as a wooden board, a plywood, and a metal plate, and a bottom floor is made of an air mat. I have.

[0003] By the way, the above-mentioned air boat has an advantage that it can be folded compactly by bleeding air and is convenient for transportation. Therefore, when the bottom floor portion is formed of a plate material, for convenience of folding the airboat, the airboat is not formed of a single plate but is formed of a plurality of plate-like bodies, which are formed so as to be divided or foldable. General. Therefore, in such a configuration, it is troublesome to assemble and connect a plurality of plate-like bodies when using them, and to divide or fold them when storing them. Also, the weight of the plate material etc. increases,
It was inconvenient to carry. Furthermore, since the plate material is hard, it has poor cushioning properties, and good riding comfort cannot be obtained.

[0004] On the other hand, the bottom floor made of an air mat can be used as a single bottom floor only by filling with air when using an air boat, and can be folded compactly if air is released when stored. The assembly work was simple. In addition, the air mat bottom floor was rich in cushioning properties, and provided good ride comfort.

[0005] In addition, the above-mentioned air boat has a bottom floor portion in order to obtain the same maneuverability as the air boat having a hard bottom, such as a needle keeping property, a turning property, a wave breaking property and an acceleration property. It is also known that an air keel in the shape of a trunk is provided between the hull and the bottom sheet.

[0006] The purpose of this air keel is to improve maneuverability such as needle keeping, turning, wave surpassing, and acceleration, which are equivalent to those of an air boat having a rigid bottom, even in a compactly foldable air boat. In order to make the bottom of the airboat into a V-shaped cross section, it is provided between the bottom floor and the bottom sheet, and its shape gradually increases in diameter from the bow to the start of warping of the airframe. ,
The maximum diameter is obtained at the start of the rise of the airframe, and the diameter gradually decreases from the start of the rise of the airbody to the bow.

[0007]

However, when the engine is mounted on the airboat provided with the air keel and the vehicle is driven on water, particularly when the vehicle is accelerated to the start of the gliding state, a large portion is generated at the start of warping of the airframe. Since the water pressure is applied, there is a problem that the V-shaped cross section of the air boat collapses and acceleration performance is impaired. Therefore, as the bottom floor of this type of air boat having an air keel, an air mat bottom floor, which is less rigid than a plate made of air, is inappropriate because the bottom plate shape is deformed by pressure from below. Was thought.

The present invention is also applicable to an air mat bottom floor which has the advantages of excellent assembling and portability and good ride comfort as described above, and is excellent in acceleration and the like by applying an air keel under the bottom floor. The purpose is to provide an air boat.

[0009]
