Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a water jet propelled small water vehicle for one to three people.

(Prior Art) A small water vehicle that can be steered with a handle and travels on water by driving a jet pump with an engine is disclosed in, for example, Japanese Patent Laid-Open No. 63-43894.

The small water vehicle of the above-mentioned publication is characterized in that the upper end of the bulwark is bent outward in an inverted U-shape, and the rear end of the bulwark faces toward the stern with surface contact between the deck member and the hull member. There is.

In the above configuration, the 64th
As shown in the lower right corner of page 2, lines 9 to 18, as the small water vehicle slides, waves tend to be launched backwards and upwards from the water surface along the ship's side plate 22, but the water is shaped like an inverted U. It is blocked by a bulwark 88 formed in the bulwark 88, and is prevented from being launched onto the hull. Furthermore, since the rear end of the bulwark 8B does not have a bent portion and extends linearly rearward, water passing through this portion escapes rearward and is not washed up onto the hull. In addition, waves are not blocked in this part, which has the effect of not increasing propulsion resistance.

(Problem to be Solved by the Invention) However, the above-mentioned small water vehicle has its rear end connected to the side plate 22.
and the rising portion 31 of the hull member are in surface contact,
This mating surface appears at the stern and spoils the appearance.

If a suitable value is attached to the mating surfaces in order to maintain the aesthetic appearance, the sieve, its attachment parts, and the number of man-hours for attachment will increase.

(Means for Solving the Problems) In order to solve these problems, the present invention connects an upper hull and a lower hull to each other at peripheral flange portions, and projects the flange portions outward from the outer surface of the rising portion of the boat. A small water vehicle is formed by curving inward from the maximum width position to the stern and descending from near the maximum width position to the rear deck of the boat towards the stern.

(Function) The beauty of the boat is improved without requiring any man-hours for assembling the hull, and the planing performance is not significantly affected.

(Example) Embodiments of the present invention will be described below based on the accompanying drawings.

Fig. 1 is a plan view of a small water vehicle according to the present invention, Fig. 2 is a side view thereof, Fig. 3 is a bottom view thereof, Fig. 4 is a rear view thereof, and Fig. 5 is a side view thereof.
The figure is a sectional view taken along the line AA in FIG. 2, and FIG. 6 is a sectional view taken along the line BB in FIG.

As shown in FIG. 5, the small water vehicle 1 has a flange portion 3a on the periphery of the lower hull 3 and a flange portion 4 on the periphery of the upper hull 4.
The hull 2 is formed by joining the two parts a to each other.

As shown in FIG. 1, in the upper hull 4, a handle 5 of a steering device is rotatably installed approximately at the center of the hull 2, and a front half deck 4b is formed in front of the handle 5.
Also, a seat 6 suitable for the driver to sit behind the steering wheel 5
A second half deck 4C, which is one step lower than the first half deck 4b and suitable for footrest, is provided on the left and right sides of the seat 6.

This latter half deck 4c has a front edge connected to the first half deck 4b by an upright wall 4d, a rear end open to the second half, and an outer edge connected to the rising portion 7. As will be described later, this rising portion 7 is a wall that continues to the touch and prevents his intrusion.

A pump housing 8e containing a fuel tank 8a, an engine 8b, a propulsion @8C, and an impeller 8d is interposed inside the hull 2 from the bow side to the stern side as shown in FIG.

In the lower hull 3, as shown in Fig. 3, a water supply port 3C for the pump housing 8e is opened on the bottom surface 3b of the boat, and the injection port 3e of the pump housing 8e is exposed to the stern of the boat. It forms an outer chine 3f and an inner chine 3g.

The outer chines 3f and inner chines 3g are formed in the shape of protrusions between the boat bottom surface 3b and the gunwale surface 3d, as shown in FIG. It also maintains sharp turning characteristics.

FIG. 5 is a side view taken along the line A-A in FIG. 2, showing a cross-section of the hull slightly rearward from the handlebar 5, and rubber mats 9, which have a non-slip effect, are placed on the rear decks 4c, 4c on the left and right sides of the seat 6. 9 is attached, and the latter half decks 4c, 4c are connected to the rising portion 7.

This rising portion 7 extends upward from an inner surface 7a extending obliquely upward from the rear deck 4C, a flange portion 4a of the upper hull extending further outward from the inner surface 7a, and a gunwale surface 3d of the lower hull. The outer surface 7b and this outer surface 7b
The flange portion 3a of the lower hull is bent outward from the flange portion 3a of the lower hull.

The joint portions of the flange portions 3a, 4a are as shown in FIG. 8, and are characterized by extending outward from the outer surface 7b. The portion is covered with a cushion material 10 attached.

For example, the cushioning material 10 made of molded rubber is formed to surround the side surface of the boat body 2, as shown in FIG. 7, which is a view in the direction of arrow C in FIG. It acts to absorb.

As shown in FIGS. 1 and 2, the flange portions 3a and 4a are formed on the outer periphery of the hull 2, and in particular are gently curved inward from the maximum boat width M position behind the handle 5 to the stern. .

Furthermore, as shown in FIG. 2, the flange portions 3a and 4a gradually descend from near the maximum width M of the boat to the stern of the boat and reach the deck 4c in the latter half.
matches the level of

The shapes of the flange portions 3a, 4a that curve inward and descend are generally as shown in FIG. 4, but in more detail in FIG. 6, the imaginary line E indicates the flange near the maximum width M of the boat It curves downward from here as shown by an imaginary line F.

As described above, in this embodiment, the small water vehicle 1 is characterized by lowering the flange portions 3a, 4a while curving them inwardly.
A beautiful appearance can be maintained by preventing the mating surfaces from appearing at the rear.

Further, in this embodiment, the small water vehicle 1 has a water supply port 3C opened on the bottom surface 3b of the boat, and sand is easily sucked in through the water supply port 3C, so that the small water vehicle 1 needs to stay at a certain depth. At this time, the occupants in the water will board the boat from the stern, and the flanges 3a and 4a, which curve downward, serve as effective clues to assist the occupants.

Further, in the embodiment, a profile is adopted in which the stern is narrowed inward to improve drainage of the rear half of the boat, especially the gunwale 3d, in order to reduce the influence on the planing performance due to the overhang of the flange portion.

In this embodiment, the flanges 3a and 4a are curved downward while maintaining the space between the inner surface 7a and the outer surface 7b of the rising portion 7 to obtain the above profile, so that the rising portion 7 extends over the entire length of the boat. Provides good buoyancy.

(Effects of the Invention) As described above, the present invention provides a small water vehicle that is excellent in appearance and maintains stable running performance.
