にキールを突出させ、さらに底面前部がやや上方へ上が
る構成を取っている。The air boat travels by the propulsive force of the outboard motor, and in order to improve the traveling performance, the air boat has a configuration in which the keel is projected on the bottom surface and the front portion of the bottom surface is slightly raised.
この前部を上げる構成は、主にキールの形状により行っ
ており、底布を上方に曲げる部分のキールの太さ、ある
いは高さを大きくして行っている。The configuration for raising the front portion is mainly performed by the shape of the keel, and is performed by increasing the thickness or height of the keel at the portion where the bottom cloth is bent upward.
底布は、その周囲を気胴底部およびトランサム板の底面
に接着固定されるとともに、底布と底板の間に、エアボ
ート幅方向の中央に前後方向に亙ってキールを設ける
為、底布はキールの有る部分が底方向に突出する形状と
なる。The bottom cloth is adhesively fixed to the bottom of the body and the bottom of the transom plate around its periphery, and the keel is provided between the bottom cloth and the bottom plate in the center of the width direction of the airboat in the front-rear direction. The part with the keel has a shape protruding toward the bottom.
また、従来の底布は、気胴を構成する素材と同じ素材の
もの、例えば布帛両面をトッピングしたものを使用して
いた。そして、従来の底布の形状をエアボートの横断面
で示すと左右の気胴底部材とキール底部間にほぼＶ字形
で、その左右の面はほぼ平らで真っ直ぐ張られた形状で
あった。（第５図参照） 《この考案が解決しようとする課題》 エアボート等の船舶の走行性、特に船外機を取り付け、
その推進力により走行する船舶の走行性はキールの突出
形状により、性能が左右される。特に直進性、旋回性、
凌波性は左右されやすい。Further, the conventional bottom cloth is made of the same material as that of the body, for example, a cloth with both sides of the cloth topped. When the shape of the conventional bottom cloth is shown in the cross section of the air boat, it is substantially V-shaped between the left and right body bottom members and the bottom of the keel, and the left and right surfaces thereof are substantially flat and stretched straight. (See Fig. 5) << Problems to be solved by this invention >> Travelability of a ship such as an air boat, particularly, mounting an outboard motor,
The propulsive force of the marine vessel traveling depends on the keel's protruding shape. Especially straightness, turning,
Riding ability is easily affected.
即ち、エアボート等の底面形状はキールの形状がはっき
りと出る方が、上記の性能が向上する。これは、気胴底
部とキール底部間の底布が、Ｖ字形の左右の面が平らよ
り凹状にへこんだ方が良いともいえる。That is, the above performance is improved when the keel shape is more apparent in the bottom shape of the air boat or the like. It can be said that it is better that the bottom cloth between the bottom of the body and the bottom of the keel is concave rather than flat on the left and right sides of the V-shape.
しかし、従来のように気胴と同じ素材を底布に使用して
もこのような凹こみを底面に形成することは難しいとい
う課題があった。However, there is a problem in that it is difficult to form such a recess on the bottom surface even when the same material as the body is used for the bottom cloth as in the conventional case.
この考案は、前後と左右の伸張率の異なる特性を有する
素材の底布を使用することで上記の課題を解決したエア
ボートを得ることを目的とする。An object of the present invention is to obtain an air boat that solves the above-mentioned problems by using a bottom cloth made of a material having different expansion ratios in the front and rear and in the left and right.
《課題を解決する手段》 この目的を達成する為、この考案は、底面を底布で構成
し、キールを有すると共に、底面前部がやや上方へ上る
ようにしたエアボートの底布を、エアボートの前後方向
より左右方向の伸張率が大きい底布で構成している。<Means for Solving the Problems> In order to achieve this object, the present invention has a bottom cloth composed of a bottom cloth, has a keel, and has a bottom cloth of an air boat whose front part is slightly raised. It is composed of a bottom cloth that has a greater stretch rate in the left-right direction than in the front-back direction.
特に、前後方向より左右方向が数〜10数％の伸張率が大
きい底布を使用することで、尚、ここでいう伸張率と
は、下記の式で表されるものである。In particular, by using a bottom cloth having a stretch ratio of several to several tens% in the left-right direction rather than in the front-rear direction, the stretch ratio here is represented by the following formula.
伸張率（％）＝（最大伸張時の幅−未伸張時の幅）／未
伸張時の幅×100 《作用》 エアーボートの底布は、その周囲を気胴底部に接着固定
され、キールを底板と底布間に挿入することで、底方向
に突出するとともに、エアーボートの底部前方を上げる
ため、キールの太さあるいは高さの大きい部分で前後方
向で底方向に凸状に彎曲している。Stretch rate (%) = (width at maximum stretch-width at non-stretch) / width at non-stretch x 100 << Action >> The bottom cloth of the air boat is adhesively fixed around the bottom of the trunk to secure the keel. By inserting it between the bottom plate and the bottom cloth, it protrudes in the bottom direction and raises the front part of the bottom of the air boat.Therefore, in the part with a large thickness or height of the keel, bend in a convex shape in the front-back direction in the bottom direction. There is.
また中に空気を充填した気胴は、前側が平面半円形状で
あるので、これによる平面の彎曲と、キールの太さ、高
さの違いによる垂直方向および左右方向への彎曲によ
り、底布は張るが、底布が性質がエアボート前後方向で
伸張率が小さく、左右方向では伸張率が大きいので、こ
の状態では底布は、キールから左右の気胴底面に至る部
分で凹状にへこむ。特にキールの太い部分からの底布の
凹みが大きい。In addition, since the front side of the body filled with air has a flat semi-circular shape, the bottom cloth is curved due to this and the curvature in the vertical and horizontal directions due to the difference in the thickness and height of the keel. Although it is stretched, the bottom cloth has a small expansion rate in the front-back direction of the air boat and a large expansion rate in the left-right direction, so in this state, the bottom cloth is dented in a concave portion from the keel to the left and right bottoms of the trunk. Especially, the bottom cloth has a large dent from the thick part of the keel.

ム板（５）の下辺に接着固定される。The bottom cloth (2) is adhered and fixed around the bottom cloth (1) to the bottom of the transom plate (5).
底布（２）は、布地の縦方向、横方向の伸張率が異なる
構成のものを使用する。即ちエアボートの前後方向（布
地の縦方向を使用）においての伸張率より、左右方向
（布地の横方向を使用）においての伸張率が大きい布地
を使用する。この布地の構成は、縦方向に低伸張度の糸
（例えばビニロン、ポリエステル等）、横方向に高伸張
度の糸（例えばナイロン等）を使い、これを織りあげる
構成であり、これによって、横方向が縦方向より伸張率
の大きい布帛となる。As the bottom cloth (2), cloths having different stretching ratios in the longitudinal direction and the transverse direction are used. That is, a fabric is used that has a greater expansion rate in the left-right direction (uses the lateral direction of the fabric) than in the front-back direction (uses the longitudinal direction of the fabric) of the air boat. The structure of this fabric is such that a low-extension yarn (such as vinylon or polyester) in the longitudinal direction and a high-extension yarn (such as nylon) in the transverse direction are used to weave this, The fabric has a greater stretch rate than the machine direction.
他の布地の構成として、打ち込み密度を、縦方向に比較
し、横方向の密度を小として布地を織りあげ、横方向の
伸張率の大きい布帛を構成する。As another structure of the fabric, the densities are compared in the longitudinal direction, the fabric is woven with the lateral density being low, and a fabric having a large expansion rate in the lateral direction is constituted.
その他、布地の横方向の織り方のみを、綾織り等の伸び
が大きい織り方にし、縦方向より横方向の伸張率が大き
い布帛を構成してもよい。In addition, only the weave in the lateral direction of the fabric may be a weave having a large elongation such as a twill weave, so that a fabric having a greater expansion rate in the lateral direction than in the longitudinal direction may be configured.
底板（３）は、エアボート内部の底面を形成するもの
で、気胴（１）内側に着脱自在に敷く硬質合成樹脂板、
アルミ板、木質合板等からなり、数箇所で折り畳み可能
な構成である。The bottom plate (3) forms a bottom surface inside the air boat, and is a hard synthetic resin plate laid detachably inside the air cylinder (1),
It is made of aluminum and wood plywood, and can be folded at several places.
エアキール（４）は、エアボート幅方向中央に前後方向
に亙って底布（２）と底板（３）の間に挿入固定する。
エアキール（４）は、内部に空気を充填した変形の円筒
形状であり、エアボートの気胴（１）の彎曲開始部分の
位置の太さの径を最太く構成している。The air keel (4) is inserted and fixed between the bottom cloth (2) and the bottom plate (3) in the center of the width direction of the air boat in the front-rear direction.
The air keel (4) has a deformed cylindrical shape in which air is filled therein, and is configured to have the largest diameter at the bending start portion of the air cylinder (1) of the air boat.
底布（２）は、気胴（１）に空気を充填し、エアキール
（４）を挿入して、エアボートを組み立てた場合、前後
方向はエアキール（４）の太さの違いに沿って彎曲し、
前後方向に緊張して張られ、左右方向も中央のエアキー
ル（４）を中心に突出し凹状に張られる。この組み立て
時の底布（１）の伸張率は左右方向は大きく約５％、前
後方向は小さくて約１〜２％である。このように伸張率
が大きいと、エアキール（４）底部を中央頂線として、
左右の気胴（１）底部に至る張られた面は断面Ｖ字形よ
り凹状に凹こむ。この凹み具合はエアキール（４）の最
も太い箇所で最大である。また、底布（２）は前後方向
では伸張率が小さいので、エアキール（４）長手方向に
沿って、緊張して張られる。When the air cloth (1) is filled with air and the air keel (4) is inserted into the bottom cloth (2) to assemble the air boat, the bottom cloth (2) bends along the difference in thickness of the air keel (4). ,
The tension is stretched in the front-rear direction, and also in the left-right direction, the air keel (4) at the center is protruded and stretched in a concave shape. The expansion rate of the bottom cloth (1) at the time of assembly is about 5% in the left-right direction and about 1-2% in the front-rear direction. When the expansion rate is large like this, the bottom of the air keel (4) is set as the center top line,
The stretched surface reaching the bottom of the left and right air bladders (1) is recessed from the V-shaped cross section. The degree of this depression is maximum at the thickest part of the air keel (4). Further, since the bottom cloth (2) has a small expansion rate in the front-back direction, it is tensioned and stretched along the longitudinal direction of the air keel (4).
このように、底布（２）は、エアキール（４）を挿入し
てエアボートを組み立てるだけで、エアキール（４）と
左右の気胴（１）底部間の底面を凹面状にしてキール形
状を突出させるが、さらに走行中も底布（２）の左右方
向の伸張率が大きいので、下からの水圧で、よりキール
形状がはっきりとでる。In this way, the bottom cloth (2) is formed by inserting the air keel (4) and assembling the air boat to make the bottom surface between the air keel (4) and the bottoms of the left and right bladders (1) concave and project the keel shape. However, since the lateral stretch rate of the bottom cloth (2) is large even while the vehicle is running, the keel shape becomes more distinct due to the water pressure from below.
また、第４図のようにエアキール（４）の代わりに木製
キール（７）を使用するエアボートでも、底布（２）
は、木製キール（７）の底部と気胴（１）の底部間で凹
面を形成するが、エアキール（４）よりキール形状は鋭
く成り、走行性の向上への効果は顕著である。Also, as shown in FIG. 4, even in an air boat using a wooden keel (7) instead of the air keel (4), the bottom cloth (2)
Forms a concave surface between the bottom of the wooden keel (7) and the bottom of the air cylinder (1), the keel shape becomes sharper than that of the air keel (4), and the effect of improving running performance is remarkable.
《考案の効果》 したがって、この考案によればエアボートの走行性、特
に直進性、旋回性、凌波性が非常に向上するという効果
がある。<< Effect of Device >> Therefore, according to this device, there is an effect that the traveling property of the air boat, particularly the straight traveling property, the turning property, and the wave surging property are significantly improved.
特に、キールが木製キールであると、この効果がより顕
著である。In particular, this effect is more remarkable when the keel is a wooden keel.
さらに、エアビートの前後方向においては底布の伸張率
が小さい為、キール前後方向に緊張して張ることがで
き、エアボートの剛性を向上させるとともに、走行中前
後方向に皺等が出来にくくなるので、エアボートの走行
性も向上する。Furthermore, since the stretch rate of the bottom cloth is small in the front-rear direction of the air beat, it can be tensioned and stretched in the front-rear direction of the keel, improving the rigidity of the air boat and making it difficult for wrinkles and the like to be formed in the front-rear direction during traveling. The traveling performance of the air boat is also improved.
