るものである。[Detailed Description of the Invention] Recently, by using carbon fiber reinforced plastic (hereinafter referred to as CFRP), it is possible to manufacture a lightweight hull with excellent strength. By utilizing the spring characteristics of CFRP, the hull is supported in the air by a float. Attempts have been made, such as running or gliding on the surface of the water at high speed (hereinafter referred to as jumping).
The present invention relates to a leg structure of a watercraft that slides or jumps.

強度をもって構成することが困難になる。If the hull is supported by a plurality of floats and springs, the position of the center of gravity of the boat is inevitably increased and the float intervals are widened, making it difficult to construct the springs, shock absorbers, etc. with strength.

走時の姿勢制御舵である。As shown in FIG. 1, FIG. 2 and FIG. 3, a wing 2 of appropriate strength is continuously provided on a hull 1, and a shock absorber (hereinafter referred to as an absorber) 3 is shown in FIG. 4 and FIG. In consideration of the movement angle, it hangs down and is freely connected to the float 4, and a leaf spring 5 of CFRP reaching from the float 4 to the vicinity of the continuous portion of the wing 2 and the hull 1 is provided and connected integrally. WL is the water surface, P is the propeller duct for propulsion, R is the rudder, and W is the attitude control rudder during jumping.

な応力を分散して受け持つところにある。The structure of the leg according to the present invention is as described above. The characteristic feature of the leg is that, in sliding or jumping at high speed, the magnitude of the impact force due to the collision with the water surface is the square of the speed. However, according to the present invention, the absorber 3 at the moment of receiving an impact force is fixed for a moment due to its characteristics, so that the blade 2, the absorber 3 and the leaf spring 5 of the CFRP are proportional. Form a fixed triangle and disperse and handle the momentary complex and huge stress that the float 4 receives.

ーバー3および板バネ5に分散し、極めて軽量な構成に
よって充分な耐力をもつ脚を構成することができる。That is, during normal traveling, the absorber 3 and the leaf spring 5 move freely to exert the spring effect.
At the moment of collision with the water surface, the impact force is dispersed to the wing 2, the absorber 3 and the leaf spring 5, and a leg having sufficient proof strength can be constructed with an extremely lightweight construction.
さらに、アブソーバー3の機能喪失事故に際しては艇
体1の自重により必然的に脚の構成が固定三角形となり
危険を最小限度に止める利点が得られる。Further, in the event of a loss of function of the absorber 3, the leg structure inevitably becomes a fixed triangle due to the weight of the hull 1, which has the advantage of minimizing the risk.
