Abstract

PURPOSE:To function as a buoyant member upon upset of vessel maintaining a 90 deg. inclined condition so as to block further rotation by employing a buoyant structure in a steering pole projecting over the deck and secured to a deck member. CONSTITUTION:A tubular steering pole 70 is so secured to a deck member as to project over the deck on the center line of the hull 100 to employ a buoyant structure in the steering pole 70. Upon upset of the hull 100 to submerge the steering pole 70, the steering pole 70 will function as a buoyant member. Consequently, it is maintained under approximately 90 deg. rotated condition to prevent further inclination. In such a manner, the hull 100 can be raised easily in the water.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a small boat that is mainly a one-man boat that sails at high speed on the sea.

(Prior Art) Recently, small boats with engines that glide on water have come into wide use. This ship glides on the water surface and performs various operations (movements) such as sudden starts and sharp turns, and as a result, it often capsizes. In addition, in the event of a capsize, it is easy to raise the boat up in the water so that it can sail again.
It is hoped that this will happen in the 11th building.

In conventional ships of this type, when the ship capsizes, the ship turns around (180 degrees
'rotation), which has the disadvantage of being difficult to wake up underwater.

(Objective of the Invention) This invention was made in order to eliminate such conventional drawbacks, and it is possible to create buoyancy on the steering pole, so that when the ship capsizes, it will not roll over (rotation around 90 degrees). To provide a small boat in which the hull is kept in a state where the hull can be easily raised.

(Structure of the Invention) In the present invention, a cylindrical steering pole is fixed to a deck member so as to protrude above the deck on the centerline of the hull, and several steering handles are provided near the upper end of the steering pole. The interior of the above-mentioned steering pole is constructed as a buoyant body (1η structure).

In the above configuration, since the steering pole is formed to protrude upward, if the boat capsizes and the steering pole is submerged in the water, this steering pole acts as a buoyant body, tilting the boat approximately 90 degrees. This will prevent further rotation and keep the hull in a state where it is easy to raise the hull.

(Example) In FIGS. 1 and 2, the hull 100 has a bottom plate 20
The area surrounded by the upper deck 1:21 formed forward of the center of the hull and the deck member rearward thereof is configured to be a drainage volume, and is surrounded by the bottom plate 20 and the upper deck 21. There are essentially two sealed engine compartments. Further, on the rear side, there is a seat base 40 that projects on the hull centerline, and bases 4 on both sides of the seat base 40.
A deck member consisting of a foot deck 30 integrally formed with the bottom plate 20 is formed, and this tool deck 30 is opened at the stern end, and both sides of the foot deck 30 rise to form a rising part of the bottom plate 20 (ship side plate). ) constitutes the gunwale 90. A seat 50 is formed above the base 40, a steering pole 70 is formed in front of the seat 50, and a steering handle 60 is attached to the upper end of the steering pole 70 via a support 61.

An engine 14 is disposed in the engine room, and a propeller (not shown) is rotated by the engine 14.
Suction water from the water suction port 32 on the bottom of the ship and pass it through the flow path 33,
Propulsive force and turning force are generated by jetting water backward from a nozzle 34 that swings horizontally at the stern.

A hatch cover 28, which is an extension of the upper deck 21, is attached to the upper side of the engine room.

The steering pole 70 is formed of a cylindrical body having a sealed space 77 therein, and a partition wall 71 is formed inside near the lower end thereof. On the other hand, an upwardly projecting extension part 41 is formed on the front side of the base part 40, and the lower end part of the steering pole 70 is connected to this extension part 41 by suitable means such as screws. The extension portion 41 and the partition wall 71 are provided with cylindrical portions 42 and 72 facing each other,
The two cylindrical parts 42 and 72 are connected to each other by a connecting pipe 47 that is fitted onto them, and a cable (not shown) connected to the steering handle 60 and the engine 14 is inserted through the connecting pipe 47 . Instead of making the inside of the steering pole 70 a hollow buoyant body as described above, it may be filled with a suitable lightweight member such as a foam material to form a buoyant body.

In the above configuration, the extension portion 41 and the hatch cover 28
The lower side of the is the engine room which is a substantially sealed space as mentioned above, and this engine room and the base/I2, 7
Is the space 77 that passes through 2 also real? It is a closed space and has a watertight structure. Therefore, the hull 10
0 capsizes and the steering pole 70 is submerged below the water surface 99, the steering pole 70 acts as a buoyant body and is therefore kept in an overturned state (rotated approximately 90 degrees) as shown in Figure 3. , if it leans further than that, it becomes defense 1. Therefore, the hull 100 can be easily raised underwater.

The reason why the steering pole 70 is constructed as a separate member from the extension part 41, which serves as a deck member, and can be attached with screws, etc. is to facilitate the work of attaching steering cables, etc. Although this is done so that the volume can be reduced by removing it during transportation, it may also be constructed integrally with the deck member.

(Effects of the Invention) As explained above, in the configuration of the present invention, since the steering pole is formed to protrude upward, when the boat capsizes and the steering pole is submerged in water, the steering pole becomes a buoyant body. It will act as
For this reason, the hull is maintained at an approximately 90' inclination to prevent further rotation, thereby keeping the hull in a state where it is easy to raise the hull.
