Abstract

PURPOSE:To facilitate movement in a vessel by forming decks continuously into approx. a single plane, opening the stern, and thereby exhausting the water cast on the deck quickly from the stern. CONSTITUTION:A seat table 4 and a maneuvering handle table 6 are formed in the center line of the hull in such a way as protruded on a deck member 3, and on both sides a deck 30 is formed between bull work 8 while another 33 at the front, which are continued together into a single plane, and the stern of this deck 30 is left open. Accordingly the water cast onto the decks 30, 33 from the water surfaces associate with coasting and turning of this propelling vessel concerned will be exhausted smoothly from the tail of the deck 30 to the stern because the decks 30, 33 are continued, and inside the vessel is thus free from stagnating water. These continuous decks 30, 33 forming approx. one single plane should facilitate movement on the vessel very much.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a small jet propulsion boat that can carry one person or two or three people and travel on the sea at high speed.

(Prior Art) Conventionally, small jet propulsion boats, which are small boats equipped with engines that glide on water, have been widely used.

In order for this propulsion boat to glide on the water at high speed and perform various movements, a seat is provided on the centerline of the hull, and an operating handle is provided at the front of the boat. I'm trying to get on board and control it.

[Problem to be solved by the invention]

Since the jet propulsion boat glides on the water at high speed and performs various movements, waves are likely to be washed up onto the boat while the boat is gliding.

For this reason, it is necessary to ensure that the launched water can be easily drained. Furthermore, recently, these jet propulsion boats have come to be used not only for gliding, but also for various purposes such as fishing, and it is therefore desirable to be able to easily move people inside the boat.

However, conventional structures do not take into consideration the drainage function and the movement of people inside the ship.

This invention was made to solve these conventional problems, and it is a small jet that has excellent drainage function, allows people to move easily on board, and is useful for various purposes. The purpose is to provide a propulsion boat.

[Means to solve the problem]

The present invention is a small jet propulsion boat in which a deck member and a hull member, each integrally molded with FRP, are joined to each other at their peripheral edges, and the deck 1 member has a bulwark on the peripheral edge except for the stern end. At the same time, a seat and a stand for the operating handle are formed to protrude from the centerline of the hull, and a substantially single-plane deck is formed continuously on both sides and the front side of the deck with the stern end open.

[Effect]

In the above configuration, the decks are continuous and formed into a substantially single plane, and the stern end is open, so launched water can be quickly discharged from the stern end, and people can easily move around inside the ship. It's also very easy.

(Example) In FIGS. 1 to 4, a boat body 1 is made up of a hull member 2 and a deck member 3, which are each integrally molded from FRP and are joined to each other at their peripheral edges. A closed space is formed such that the portion surrounded by the member 3 serves as a drainage volume. The hull member 2 has a bottom plate 20, a ship side plate 22, and a stern plate 24, and the deck member 3 has a rising portion 31 formed on its peripheral edge excluding the stern end, and the upper end thereof is folded back to form the upper end of the ship side plate 22. (joint part 23). This rising part 31 and the ship side plate 2
2, a space is formed between them, and a bulwark 8 is formed.

Further, the deck member 3 is formed with a seat base 4 and an operation handle base 61 protruding from the center line of the hull, and on both sides there is a deck 30 between the deck member 3 and the bulwark 8, and a deck 33 on the front side.
are formed so that they are continuous with each other and formed into a substantially single plane, and the stern end of this deck 30 is formed to be open. An operating handle 60 is attached to the operating handle base 61, and a seat 50 is formed on the seat base 4 at the rear and a seat 51 at the front.

An engine room is formed below the operating handle base 61 and the seat base 4, and an engine 14, a fuel tank 15, etc. are arranged in this engine room, and the engine 14 rotates a propeller (not shown) to propel the ship to the bottom of the ship. Water is sucked through the water suction port 36, passed through the channel 37, and then jetted in a predetermined direction rearward from a nozzle 38 that swings horizontally at the stern, thereby generating turning force and propulsive force. There is.

In the above configuration, waves are launched from the water surface onto the decks 30.33 as the propulsion boat slides and turns, but both decks 30.33.
Since 33 is continuous, the launched water is deck 3
It is smoothly discharged from the rear end of the ship to the stern end and does not accumulate inside the ship. In addition, a jet propulsion boat is subject to a large heeling moment when turning sharply, but in the above configuration, the bulwark 8 on the side of the boat has a large buoyancy space, so
It has a large restoring force and excellent stability.

In addition, during normal skiing, two people 11 straddle the seat 5o, as shown in Figure 4, and when anchored off the coast for fishing etc., as shown in Figure 5, two people 11 sit in front. The space on the ship can be effectively utilized by sitting on the seat 51 facing forward and putting one's feet on the deck 33, while the other person sits facing backward on the seat 50. In such a micro-sized boat, when a person moves their seat, a large heeling moment acts and tends to become unstable, but the Detsuki 30
Since the deck 33 and the deck 33 are continuous and form substantially a single plane, movement on the ship can be carried out very easily.

Further, as shown in FIG. 3, if the seat 50 is set higher than the bulwark 8, there is an advantage that the bulwark 8 can be used as a footrest when fishing.

〔Effect of the invention〕

As explained above, according to the present invention, since the decks are formed in a continuous manner on a substantially single plane and the stern ends of the decks are open, the water launched onto the decks can quickly flow to the stern. It is discharged from the end and does not accumulate inside the ship, and it is very easy for people to move around inside the ship.
This is preferable for using jet propulsion boats for various purposes.
