Abstract

PURPOSE:To obtain a vehicle with the small turning radius by forming a casing at the rear of a narrow boat, arranging an engine, propulsion machine, fuel tank, and the like, using the upper part of the casing as a single seat, and providing a steering handle in front of the casing. CONSTITUTION:Weight bodies such as an engine 3, propulsion machine consisting of an impeller 62 and a jet nozzle 6, fuel tank 7, and battery 8 are housed at the rear of a narrow boat 1 and an engine casing 2 whose upper part is used as a single seat is provided. A steering shaft 5 is provided in front of this engine casing 2 and a steering handle 4 is mounted on the upper end 4. As a result, since the center of gravity is arranged at the rear of the boat 1, a vehicle with the small turning radius whose rear is easy to sink and that is suitable to water sports can be obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) This invention relates to a small water vehicle with excellent driving performance.

(Prior Art) Conventionally, one-person water vehicles with an engine mounted on a narrow board have been known, but in this one, the person on board F steers the boat by shifting his or her weight. be. With this structure, the turning performance is extremely poor because there is no steering device.

It is also known that the engine is mounted at the front of the board, the rudder is mounted at the rear, and the steering wheel is mounted at the front.

With this structure, the center of gravity of the boat is forward of the center, resulting in a large turning radius, which is unsatisfactory for water sports that require small turns.

(Objective of the Invention) The present invention was made based on the above technical background, and an object thereof is to provide a small water vehicle that has excellent turning performance and is therefore suitable for water sports.

(Structure of the Invention) The present invention is a water vehicle for one person, in which a casing is formed at the rear of a narrow board, an engine, a propulsion device, a fuel tank, etc. are disposed within the casing, and A steering wheel is provided on the front side, and the driver's seat is located on the casing.

(Example) In the drawings, the first half of a narrow board 1 is made up of a plastic foam core 11 covered with an FRP outer skin 12, and the second half of the board 1 has an engine casing 2 formed thereon. Heavy objects such as an engine 3, a fuel tank 7, and a battery 8 are housed inside. A steering shaft 5 is provided in front of the engine casing 2, and a steering handle 4 is formed at the upper end thereof to protrude left and right.The steering shaft 5 is covered by a casing 50, and the upper end thereof is held by the casing 50. .

The inside of the casing 50 is a ventilation chamber for ventilating the inside of the engine casing 2, and an air intake pipe 30 for supplying air into the engine casing 2 is arranged in this ventilation chamber. A ball valve 35 is attached to the pipe 30 to restrict seawater from entering when the ship capsizes. Furthermore, air suction ports 51 are formed on both sides of the front portion of the casing 50.

A jet nozzle 6 is attached to the rear end of the board 1 below the engine 3, and a water channel 63 is attached to the jet nozzle 6.
The front end of the water channel 63 communicates with the suction port 61 via the impeller 62.

The jet nozzle 6 is connected to the lower end of the steering shaft 5 via a steering wire 60, so that steering force is transmitted to the jet nozzle 6 via the steering wire 60 by operating the steering handle 4. and impeller 6
2 suction seawater from the water channel 63 to the jet nozzle 6
Propulsion and turning are achieved by jetting seawater in a predetermined direction through the aircraft.

In the illustrated example, Geno 1 - Nozzle 6 is installed on the ship's center line, but by displacing it laterally from the ship's center line, the ship will be protected from the water when the person 10 falls overboard. You can also make a natural turn and avoid going too far.

At the top of the engine casing 2 is an engine cover 3.
1 is installed (pulled), a person 10 rides on the board 1 using the upper surface as a seat, and the steering handle 4 and accelerator lever 1 are installed.
I am trying to operate 4.

33 is the carburetor, 34 is this 4:17 bretter 33
15 is an accelerator wire for operating the carburetor 33 by the accelerator lever 14. The fuel tank 7 is provided with an air vent hose 71, and the tip of the air vent hose 71 opens into the fuel return box 72, thereby preventing seawater from entering the fuel tank 7 when the ship capsizes. I'm trying to limit it.

In the above configuration, heavy objects such as the engine 3, fuel tank 7, and battery 8 are placed at the rear of the board 1, so the rear part tends to sink. Therefore, the turning performance is good and the turning radius is small. can do. Further, since the steering handle 4 is arranged in the center, the operating means such as the steering wire 60 can be short. In addition, a deck 13 is formed on the board 1 in front of the steering handle 4, so this deck 13 can be used as a platform for children.
Alternatively, it is also possible to ride on it and push the steering wheel 4 in the opposite direction to perform what is called a curved ride.

(Effect of the invention) -5= As explained above, this invention forms a casing at the rear part of a narrow board, arranges an engine, a propulsion device, a fuel tank, etc. in this casing, and It is equipped with a steering wheel and a driver's seat on the casing, and has excellent turning performance, making it suitable for water sports.
