BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a small boat having a riding section at the rear of the deck of a hull and a steering handle projecting upward from the deck in front of the riding section of the deck .

[0002]

BACKGROUND ART For example, to configure the hull from the bottom of the hull and the upper deck is provided with a tower multiplication portion to the rear portion of the deck,
A steering handle is provided in front of this riding section,
A small boat that glides over water at high speed is registered as Design No. 4497.
Conventionally known as disclosed in Japanese Patent No. 93
It In such a small watercraft, it is overturned during skiing
However, since the center of gravity of the boat is set low in the first place ,
Even capsized, it has the ability to thus reversed return to couple moment due buoyancy with the watercraft itself.

[0003]

[Problems to be Solved by the Invention] However, in a small boat, a hood that covers the engine from above is provided at the front of the deck so as to be openable and closable, and the outside air is taken into the engine air cleaner by the engine hood. for intake inlet for is opened, watercraft when capsized, the water from entering the boat. When water enters the boat as described above,
Downward posture craft is rotated 180 degrees, i.e., will be water accumulated on the engine hood side, because the inversion recovery ability is decreased, the intact boat may not be restored to its original normal attitude. This invention was made in consideration of the above situation, and the boat rotates about 180 degrees due to flooding accompanying capsizing.
Even if it does, it aims at providing the small boat which can be reversed and returned to the original normal posture .

[0004]

To achieve the above object, according to the Invention The small watercraft according to this invention is provided with the steering wheel in the position farthest from the water line of the watercraft, to the steering wheel, foamed polyethylene,
Half-molded from resin foam such as urethane foam
Put the handle in front of you,
It is detachably attached via a fastener so that buoyancy can be generated to reverse and return the boat .

[0005]

[Operation] According to this invention, the position farthest from the center of gravity
Foamed polyethylene on the steering wheel provided,
Half-molded from resin foam such as urethane foam
Put the handle in front of you,
Removable installation via fasteners and flipping the boat
Since it is possible to generate buoyancy to recover, it is possible to capsize while sliding.
More submerged in the boat, and the boat turned 180 degrees.
Even if water collects on the engine hood side, the boat itself
Of buoyancy and the half of foam made of resin foam
By generating a couple moment due to buoyancy as large as possible,
Improves the ability of the boat to reverse and effectively returns to a normal posture
It is possible to

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. Fig. 1 is a side view of a small boat according to the present invention.
There, reference numeral 1 denotes a hull, and is formed integrally with the lower portion of the hull 2 and the upper deck 3 together consisting of FRP and bonded by through the flanges 4 of their outer periphery. The deck 3 extends from the bow to the stern, and an engine hood 5 for covering an engine (not shown) in the hull 1 from above is attached to the front part of the deck 3.
The engine hood 5 is freely opened and closed by a hinge and a latch mechanism (not shown), and detachably attached to
Tei Rutotomoni, when closed, is sealed by a seal packing 6 which is fixed to the entire periphery of the deck 3 side (FIG. 1). Also, outside air is the engine hood 5, the starboard side intake opened in intake inlet inlet intake intake communicating with (not shown) passage (not shown) is provided, which is incorporated through the intake intake passage Is introduced as intake air into an air cleaner (not shown) of an engine (not shown) through the engine room.

[0007] On the other hand, the back upright wall of the engine hood 5
The lower end portion of 5A is received by the steering packing wall portion 3A integrally formed on the upper surface wall of the deck 3 corresponding to the rear of the engine hood 5 via the seal packing 6. The steering device S is installed via the steering attachment wall portion 3A.

As shown in FIG. 2, the steering device S has a steering column 7 fixed in a state of vertically protruding through a through hole 3B of the steering mounting wall 3A.
And a steering shaft 8 rotatably inserted in the steering column 7, and the steering shaft 8
Has a bar-shaped steering handle 9 integrally formed in a T-shape at the upper end thereof, and an operating member 10 is attached to a downward projecting portion of the steering shaft 8 and a cable 11 connected to the operating member 10. The stern jet nozzle (not shown) can be operated for steering.

Further, as shown in FIG. 1, a portion of the deck 3 corresponding to the rear side of the steering device S has a seat mounting portion 12 projecting upward at the center in the width direction of the boat, and this seat mounting portion 12 Located on both sides of
It is integrally formed in a convex shape with leg rests 13 and 13 lower than the seat mounting portion 12. The seat mounting portion 12
A seat (boarding portion) 14 is attached to the upper surface portion of the.

In the small boat having the basic structure as described above, the buoyancy generating means 15 is provided on the steering handle 9.
It is provided. The buoyancy generating means 15 can be provided at any position above the waterline in the boat, but in the sense that it maximizes the reversal return capability, that is, the couple moment due to buoyancy, it is the most distant position from the waterline. It is provided on the steering handle 9 as described above.

That is , as shown in FIG. 3, two materials having a specific gravity of less than 1 and a specific gravity as small as possible, for example, resin foam such as foamed polyethylene or urethane foam are used.
Half-foamed body 15A, 15B of
The foam bodies 15A and 15B are detachably attached by a fastener 16 such that the handle 9 is sandwiched from the front and the rear .
ing. In the above structure, the buoyancy generating means 15 is attached to the steering handlebar 9 at the highest position in the boat.
Since it is provided, the couple moment due to buoyancy is the largest compared to the case where the buoyancy generating means 15 is provided in the other part above the waterline, which causes the boat to capsize by about 180 degrees. Even if the engine hood 5 turns right underneath to allow water to enter the boat, keep the boat above the large couple mode.
It is possible to effectively reverse and return
It

Further, the buoyancy generating means 15 is composed of a resin foam, such as foamed polyethylene or foamed urethane foam
Because it is, it is possible to freely set the buoyant generating means 15 in the preferred styling can also be effectively used as a mounting member, such as a component. Incidentally, Rukoto be formed on a sealed cavity inside the buoyancy generator 15 was shown in the above embodiments are possible.

Further, the steering handle 9 itself
And a structure having a large cavity therein, more buoyant
You may make it big. In this case,
In terms of increasing buoyancy, resin, especially high strength
It is preferably a resin .

[0014]

As described above, according to the present invention, the center of gravity is
Steering wheel located farthest away from
Resin such as polyethylene foam and urethane foam
Attach the half-split foam that is half-split from the foam,
Since it is possible to generate buoyancy that reverses and returns the boat,
When the boat overturned, the boat was rotated by 180 degrees.
And the water collects on the engine hood side
Originally, the couple moment due to the buoyancy of the boat itself
In addition, the buoyancy of the half-foam made of resin foam
Force moment is added to maximize the maximum couple moment.
Can be generated. Therefore, the capsize of the boat
The ability to reverse and reverse is improved and effective for normal posture
Can be returned to.
