It provides the body. The watercraft according to the present invention does not move forward at high speed like a conventional motor boat or a watercraft, but it floats in a vertical direction and floats from a pump device in a direction in which the floating body floats. The jet flow is ejected to generate thrust, and a part or all of this thrust is diverted from the axial direction of the main body to generate a force that moves along the water surface. The main body, with the engine and pump device loaded inside it, even when the player rides on the step formed on the upper surface of the main body,
At least the control device provided on the step and the intake port of the engine have buoyancy so that they are located on the water surface. The pump device is accommodated inside the main body, and a type that generates a large thrust is suitable, but specifically, an axial flow pump that generates a water jet is used. The rudder device is provided near the jet outlet provided below the main body, and changes the direction of the jet to move the main body in the vertical direction while floating in the water surface direction. It has a function of a kind of shutter such as a blade or a closing plate that squeezes a part of a wing or a jet. The control device may be one that operates the handlebar of a motorcycle, one that controls the helicopter, or the like that can be easily operated even on the main body that floats on the water and shakes greatly.

[Operation] In the watercraft with such a configuration, the main body floats in the vertical direction, and the player gets on the main body and operates the control device to eject the water jet from the jet port at the lower end. The main body can be floated further and the rudder device can be operated as necessary for sailing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of a watercraft according to the present invention will be described below with reference to FIGS. 1 is a side view of the watercraft 1, FIG. 2 is a front view of the watercraft 1, and FIG. 3 is a plan view of the watercraft 1. The watercraft 1 has a buoyancy chamber 2 in the upper portion and an intake port 3 in the lower side surface. And a main body 5 having a jet port 4 at the lower end, a rudder device 6 provided at the lower end of the main body 5 and operated continuously by a steering device 7 arranged at the upper part of the main body 5, and the suction port 3. It is composed of a pump device 8 provided between the jet port 4 and the jet port 4. More specifically, a step 9 having a large diameter is formed on the upper portion of the main body 5 so that a player can get on it, and a power portion such as an engine 10 and a fuel tank 11 is arranged inside the buoyancy chamber 2. The main body 5 is made of a metal such as an aluminum alloy or a molded product of fiber reinforced resin, and has a pole shape. The driving means of this is a water jet,
The suction port 3 is arranged in the middle part of the main body, and the jet port 4 is arranged in the lower part. The pump device 8 provided between them is supported by the rotary vanes (impeller) 13 by thrust bearings fixed to the guide vanes 12. The rotor blade 13 is connected to the output shaft of the engine 10 by a hollow shaft 14 extending to the center of the main body 5, and when the engine 10 is driven, the rotor blade 13 operates so that the water sucked from the intake port 3 is discharged. The main body 5 is pushed up by the thrust of the jet from the jet port 4. The rudder device 6 provided at the lower end of the main body 5 is provided with a support shaft 21 in the diameter direction of the ring body 20 as shown in FIG.
A plurality of variable direction wings 22 are provided between the ring 1 and the ring body 20. A link 23 is provided on the direction-changing wing 22a in the central portion, and two links 23,
The lower end of 24a is connected and the upper end of the grip 2 of the control device 7 is provided on the step 9 formed on the upper surface of the main body 5.
5 can be swung back and forth to change the inclination angle of the variable direction blade 22a to adjust the direction of a part of the jet flow. The base portion 7 of the pillar body 26 of the control device 7 and the receiving seat 28 protruding in the center of the step 9 are rotatably fitted, and the handle body 29 is used to rotate the pillar body 26 with respect to the step 9. Then, the hollow shaft 14 provided at the center of the main body 5
The steering shaft 30 penetrating the inside of the body rotates to rotate the ring body 20 shown in FIG. 4. As a result, the position of the variable direction vanes 22 and 22a on the main body 5 changes and the jet flow The moving direction of the main body 5 can be changed by changing the direction of. Although not shown, an air intake port provided with a check valve is opened above the column body 26, and the air taken in from this is supplied to the engine 10, and the exhaust gas of this engine 10 is It is designed to be discharged into water. Now, when operating the watercraft 1 of the present invention,
The player rides on the step 9 on the main body 5 and the engine 10
Then, the pump device 8 is driven to eject the water jet from below the main body 5. When the grip 25 is tilted forward or backward, the wire 24,
A variable-direction vane 22 forming a rudder device 6 by 24a.
Is inclined, and accordingly, a part of the jet flow deviates from the axis of the main body 5, and the component force of the jet flow causes the marine vessel 1 to start moving forward. By operating the accelerator button 25a provided on the upper end of the grip 25, the output of the engine 10 is increased, the thrust of the water jet is increased, and the forward speed is changed. By further operating the handle 29, the pillar 26 is rotated with respect to the main body 5,
At the same time, the rudder device 6 turns in a direction orthogonal to the axis of the main body 5 to change the direction of the water jet and to move forward in an arbitrary direction. In this way, by operating the grip 25, the alsel button 25a, and the handle 29, the watercraft 1 advances with the thrust of the water jet and changes its direction. However, most of this water jet is ejected in the axial line of the watercraft 1 or in a direction close to the axial line. Therefore, as the output of the engine 10 increases, the force of the main body 5 to float above the water surface increases. Therefore, the main body 5 moves up and down largely due to the vertical movement caused by the wave and the vertical movement caused by the thrust. And since a part of this water jet is used for thrust for the main body 5 to move forward, the main body 5 can be used for various water waves such as wave and vertical water jets, diagonal water jets, and movement of the player's center of gravity. As it becomes extremely unstable due to the total influence of force, there is a difference between the time it takes to get on the main body 5 and pass a predetermined route and the time it takes to fall, depending on the player's skill level and sports feeling. Will be done.
As described above, the watercraft 1 according to the present invention is difficult to move forward and generates thrust to move the main body 5 up and down, so that it becomes as if it is in a "water rodeo" state and enjoys an extremely attractive advanced game. be able to. For advanced users, buoyancy of the main body 5 is small, the area of step 9 is small, and the shape that is easy to move forward is prepared. For beginners, the area of step 9, that is, the diameter is large and the stability is high. Can be prepared. Also, for children, it is possible to make the step area even larger and to sit on it, and to make it possible to row a tarai boat. As shown in FIG. 5, the rudder device 6 is provided with a jet flow guide 31 at the tip of the steering shaft 30 and a jet flow direction control plate 32 so as to swirl the inner surface of the ring-shaped jet port 4, and the steering shaft 30 is provided with a pillar 26. It is also possible to reduce the amount of water jet on the side where the jet flow direction control plate 32 is located by rotating it together with the jet flow direction control plate 32, and to advance the marine vessel 1 in the direction opposite to the jet flow direction control plate 32. The present invention is characterized in that the water jet is mainly used as thrust in the vertical direction with respect to the main body 5 which is a floating body, and a part of this water jet is used as thrust for advancing. Therefore, the main body will change the length, the size of the buoyancy chamber, and the restoring force according to the skill level of the player, and the control device will also have various structures using handles, levers, buttons, etc. You can

The watercraft according to the present invention has an engine inside a main body that floats in the longitudinal direction, a pump device that is driven by the engine below the main body, and jets from the pump device are jetted downward. And a rudder device for changing the direction of the jet flow in the vicinity of the jet port, a step is formed on the upper surface of the main body, and a steering device is provided on the step. Therefore, the thrust of the water jet generated by the pump device causes the main body to move so as to project above the water surface, and the vertical movement due to the waves and the vertical movement due to the water jet are combined to make a large vertical movement. Further, when the vehicle moves forward, it is difficult for the main body to move in a predetermined direction due to water resistance, which makes the maneuverability even more difficult. As described above, the present invention allows the player to experience a motion not found in conventional gaming machines, and also requires a high degree of maneuverability, so that the player's willingness to challenge can be improved. There is an effect that it can be made suitable as a game machine.
