Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to a small boat which is a single passenger and sails at high speed on the sea.

[0002]

2. Description of the Related Art Recently, small-sized jet propulsion boats, which are engine-equipped small boats and are designed to slide on water, have been widely used. The propulsion boat slides on the water surface and performs various operations (exercises) such as sudden start and sudden turn. In addition, this hull has a substantially sealed space in the part surrounded by the upper deck and the bottom plate, and a fuel tank is placed in this space.The fuel tank should be inspected on land. ing.

[0003]

In the hull having the above structure,
It is desirable to be able to check the fuel tank and the remaining amount of fuel at sea.

The present invention has been made to solve the above-mentioned conventional drawbacks, and in a small boat body,
An object of the present invention is to provide a small vessel capable of checking the fuel tank and the remaining amount of fuel at sea.

[0005]

According to the present invention, a substantially sealed space is formed in a portion surrounded by an upper deck of a hull and a bottom plate, and a fuel tank is arranged in this space. An opening is formed on the upper side of the cover body and a cover is attached so as to cover the opening, and a seat for the operator is formed on the rear side of the cover body, and the cover body is provided at the front end thereof. The hinge is attached to the upper deck so that it can be opened and closed.

[0006]

In the above structure, since the cover body is provided on the front side of the seat for the operator and is rotated around the hinge provided at the front end to open and close, the operator can cover the body at sea. You can open and close to check the internal fuel tank and remaining fuel.

[0007]

1 and 2, a hull 100 includes a bottom plate 20, an upper deck 21 formed in front of the center of the hull, and a portion surrounded by a deck member behind the hull 100 as a drainage volume. An engine room, which is a space 29 substantially sealed, is formed in a portion surrounded by the ship bottom plate 20 and the upper deck 21. A seat 50 is formed so as to project from the center of the hull in the widthwise center of the hull, and a foot deck 30 that opens to the stern end is formed between the seat 50 and the gun flannel 88 on both sides. The lower sides of the foot deck 30 and the seat 50 are also configured to have a drainage volume.

The operator 11 on the seat 50 operates the hull 100 by grasping the handle 60 with his / her foot on the foot deck 30. It can be moved left and right.

An engine 14 and a fuel tank 15 are arranged in the space 29, and a propeller (not shown) is rotated by the engine 14 to suck water from a water suction port 32 at the bottom of the ship and to be formed under the seat 50. A turning force and a propulsive force are generated by injecting water backward from the nozzle 34 that swings in the horizontal plane of the stern through the formed flow path 33.

As shown in FIGS. 3 and 5, the space 29
An opening is formed on the upper side of, and a hatch cover 28, which is a cover body having a central portion protruding upward, is attached to be openable and closable so as to cover the opening. That is, the front end of the hatch cover 28 is joined to the upper deck 21 by the hinge 51, and the hatch cover 28 is opened around the hinge 51 as shown by the phantom line in FIG. At the rear end of the hatch cover 28, a locking tool 52 for keeping the closed state is attached.

The steering wheel 6 is attached to the hatch cover 28.
A steering shaft 40 having a number 0 is attached through the through shaft 27. The through portion 27 is made of a thick plate, and a handle support portion 61 is attached at the upper end thereof. The both sides 26 of the hatch cover 28 are thick plates for maintaining rigidity, and ribs 43 for beam attachment, which will be described later, are attached to the inside of the thick plates.

The both side portions 26 are provided with a hatch cover 28.
4 is continuously formed on the entire peripheral edge of the lower end of the cover, and packing 23 as shown in FIG. 4 is continuously arranged on the edge of the opening corresponding to the lower end of the hatch cover 28. The lower end of the peripheral portion is pressure-bonded to the packing 23 so that the inside has a watertight structure. Further, a beam 42 is provided on the back side of the hatch cover 28 between both side portions 26 of the hatch cover.
An end member 44 is attached to the end portion of the above, and both end portions 26 are connected to each other by a beam 42 by connecting the end member 44 and the rib 43 with a bolt 25. A bracket 41 arranged between the beam 42 and the front upper surface of the hatch cover 28 is coupled to the central portion of the beam 42. The bracket 41 is coupled to the penetrating portion 27 by a bolt. This constitutes a reinforcing member for the hatch cover 28. A bearing 46 is attached to the reinforcing member by a stopper 45, and the steering shaft 40 is rotatably held by passing the steering shaft 40 through the bearing 46.

An arm 47 is fixed to the lower end of the steering shaft 40 by tightening it with a nut 48, and the end of the steering cable 70 is connected to the tip of this arm 47 via a ball joint 49. .. A stopper 71 is attached to the lower surface of the bracket 41,
The outer tube of the steering cable 70 is held by the stopper 71. As described above, the reinforcing member including the beam 42 and the bracket 41 has a function of improving the rigidity of the entire hatch cover 28, holding the steering shaft 40, holding the steering cable 70, and guiding.

In the above structure, the operator 1 on the seat 50
Since the locking tool 52 of the hatch cover 28 is located immediately before 1, the locking tool 52 is operated to lift the rear end portion of the hatch cover 28, and the hatch cover 28 is moved to the front end as shown by the phantom line in FIG. It can be opened by rotating it about the hinge 51 of the section. Then, the fuel tank 15 can be inspected through the opening or the amount of fuel remaining in the fuel tank can be viewed. And this operation can be performed at sea.

A force is applied to the steering shaft 40 by the operator 11 gripping the steering wheel 60 to steer the steering shaft 40, and the force is received by the hatch cover 28. Moreover, since it is reinforced with a reinforcing material inside to have a structure with high rigidity,
The force is distributed to a wide range of the peripheral portion of the hatch cover 28 and transmitted to the upper deck 21. Therefore, there is no possibility that the hull will be locally deformed even if a large force is applied from the driver 11 when making a sharp turn. Further, since the hatch cover 28 formed so as to project upward has a drainage volume formed therein, when the hull is overturned, buoyancy is exerted in this portion to facilitate the hull from the overturned state. It will be.

As described above, in the structure of the present invention, the cover body is provided on the front side of the operator's seat, and is rotated around the hinge at the front end portion to be opened and closed. A person can open and close the cover at sea to check the internal fuel tank and the remaining amount of fuel.
