Abstract

PURPOSE:To prevent a hull body from being broken and contrive to enhance its safety, by a method wherein a ship's hull is constituted of a central part and both side parts, and each of the side parts is formed of a foamed body. CONSTITUTION:The ship's hull is constituted of the central part 1 and the side parts 2, the central part 1 is integrally formed in such a shape as to have a bottom plate and both side plates, while each of the side parts 2 is formed of a foamed body. The side parts 2 are detachably fitted to the central part 1 by connecting means 4 so that the parts 2 consisting of the foamed bodies make contact with the outside surfaces of the side plates of the central part 1, and a ship's bottom is formed by the central part 1 and the side parts 2. Accordingly, since the float bodies at both side parts are formed of the foamed bodies, the danger of float bodies being broken and water entering the ship can be eliminated.

Description

[Detailed description of the invention] This invention relates to a new ship structure.

In recent years, so-called rubber boats have been widely used as simple leisure river boats, with the hull shaped like a plastic sheet sealed with air. This can be made compact when not in use, making it convenient for transportation and handling (there is a risk of warping, so there is a problem with safety, and the durability is very weak, so it cannot be fixed). It is not possible to maintain the ?Fk running surface, which increases the running resistance, and has disadvantages such as poor durability and time-consuming assembly.

This invention was made to solve these conventional drawbacks, and provides a ship that has a structure that is convenient to handle, and has excellent safety, sailing performance, and durability. . In other words, this invention provides mutually independent midship
η (and one part on both sides are removably connected by a connecting means, the central part is integrally formed in a shape having a bottom plate and both side plates, and both side parts are formed of a foam and have a joint shape f, +
In p, both sides are in i+'ii contact with almost the entire curve of the side surface of the center part, and the bottom of the ship is formed by the center part and both sides.

Hereinafter, four practical examples of this invention will be explained with reference to the drawings.

Both side parts 2 are attached to both sides of the center part 1 of the hull, and the front part 1 of the center part 1:
! 2 I have been asked. The central part 1 is integrally formed with a bottom plate and both side plates, and the side parts 2 are integrally formed with plastic shells 1. On the outer surface of the side plates of the central part 1, The inner surfaces of both side sections 2 are in surface contact with each other over the entire surface, and the center section 1 and both side sections 2 are connected by a band 4. At the end of the band 4, a mounting bracket is attached to the outer surface of the bottom of the center section 1 and the inner surface of the boat side. 40 is fixed, and the band 4 is removably connected thereto.

The side part 2 mainly functions as a floating body,
It is possible to adopt foamed polyethylene, foamed polypropylene, foamed polystyrene, etc., or a combination of these three types, or foamed urethane, etc., which have a density of 0501 to 0.1.
It may be molded to a culm size of 171” kg/C.

The side portion 2 also functions as a buffer in the event of a collision with another object. The central portion 1 is integrally formed of corrosion-resistant aluminum, fiber-reinforced plastic, water-resistant veneer, thermoplastic resin, or the like.

A bottom plate 5 made of foam is disposed at the inner bottom of the central portion 1. The bottom of the center part 1 is formed in a V shape to reduce the impact of water in waves, and therefore the bottom plate 5 forms a flat platform inside the ship. Furthermore, by forming the bottom plate 5 from a foam, it can also have a shock absorbing function. A storage compartment 6 is formed at the rear of the central portion 1, in which a fuel tank 60 and the like are stored. The storage compartment and the upper surfaces of both sides 2 can be used as seats for passengers. Also, the outboard motor 7 is connected to the transom board 10.
is installed.

In the above configuration, in the assembled state, the central part 1 and both side parts 2
The bottom and sides of the ship are formed by these, and since this shape is not deformed by waves, a predetermined sliding surface can be maintained and navigation resistance is low. Furthermore, since the floating bodies on both sides are made of foam, there is no risk of them breaking and flooding, making them highly safe. Moreover, when not in use, the band 4 can be removed and the both sides 2 can be stored in the center part 1, and in that state, the band 4 can be used on the platform 1 on the roof of the car 11 as shown in FIG. This makes it very convenient to transport and store, as it has a compact configuration. In addition, when using, both sides 2 are connected to the center 10.
It is only necessary to connect them with bands 4 according to both sides, and assembly can be easily performed.

As explained above, the present invention consists of a center part and both side parts, and the side parts are made of foam and are removably connected to the center part to form a hull. It is safe because there is no risk of the floating body breaking, the sliding surface can be maintained constant, the sailing resistance is low, it is easy to assemble, and it has excellent durability.
