Description

[Detailed Description of the Invention] The present invention relates to a deck structure for a small boat having a cabin protruding from the deck.

For example, conventional deck structures for small ships include:
There are those shown in FIGS. 1 to 3. Each part is integrally molded with reinforced plastic, and a deck 2 is joined to the hull 1 on the side 3 with a sealing material 31 interposed therebetween, and a deck 32 is attached to the outside. In this example, the deck 2 is joined to the entire upper part of the hull 1, and the side decks 21, 2 are attached to the rear part.
1, a rear deck 22, surrounded by these forms a cockpit 23 which is the usual place for the occupants; the front part forms a front deck 24, and a cabin 4 projects from the rear of the front deck 24. The cabin 4 is formed narrower than the hull width by the side 3;
A step portion 25 having a continuous height is formed on the general surface of the front deck 24 as a passage for the passenger. A coaming portion 26 protrudes higher than the general surface of the front deck 24 from the gunwale 3 on the outer periphery of the front deck 24 to protect the front deck 24 and the step portion 25 from waves.
is formed. Rear end 27 of combing portion 26
A drain groove 29 is formed between the side deck 21 and a wave shield part 28 which is formed into a notched shape and is provided to connect the side deck 21 and the cabin. (Jitsukai 56-
(Refer to Publication No. 160192) However, in the above-mentioned conventional deck structure of a small boat, since the step portion 25 is continuous with and forms a part of the general surface of the front deck 24, the water on the front deck 24 does not flow into the step. A drain groove 29 is required to prevent water from flowing directly onto the portion 25 and entering the pit. For this reason, the shape of the area near the rear end of the step 25 becomes complicated, and as shown in Figure 2, which is a view of the part in Figure 1 from the back, when molding reinforced plastic, areas near the drainage groove 29 are narrow. Because of this, it is difficult to insert tools, and reinforcing fibers such as glass fibers are difficult to fit into, so defects such as bubbles and cracks are likely to occur. Another problem was that because the steps formed into waterways, they easily got wet, making it dangerous for feet to slip.

The present invention was developed by focusing on the above-mentioned conventional problems.The deck structure of a small boat solves the above-mentioned problems by preventing the step from becoming a waterway and making it difficult to get wet, and by simplifying the shape of the surrounding area. is intended to provide.

In order to achieve such an object, in the present invention, in a deck structure for a small boat in which a cabin is protruded from the deck, a first wave shield part is provided on the front surface of the cabin to reach the gunboard side, and this first wave The shield part prevents most of the waves that hit the front deck, and a step part connected to the back of the first wave shield part is formed on the side of the cabin, and the first wave shield part protects the step part. A second wave protection part is provided at the rear end of the step section across the cabin and the gunwale to prevent water from penetrating into the cockpit even if the step section is hit by waves due to large waves, etc. It has the deck structure of a small boat.

Hereinafter, the present invention will be explained based on illustrated embodiments.
Note that the same parts are given the same reference numerals.

4 and 5 show an embodiment of the present invention, in which a deck 2 is joined to the entire upper part of the hull 1, side decks 21, 21 at the rear, and a rear deck 2.
2. A cockpit 23 is formed, the front part forms a front deck 24, and the cabin 4 is provided protruding from the rear of the front deck 24, as in the conventional example. The front surface 41 of the cabin 4 extends to the full width of the front deck 24, and both sides of the front surface 41 form a first wave break section 24 reaching the gunwale. First wave shield part 42
may be formed separately from the cabin 4. The front and side parts of the front deck 24 are smoothly continuous with the gunwale 3. The side surface 43 of the cabin 4 is recessed to form a step portion 25 at its lower part. The step part 25 has approximately the same height as the general surface of the front deck 24, but is separated by a first wave shield part 42;
Connected to the back of 2. A second wave break section 44 is provided at the rear end of the step section 25, extending across the cabin 4, the side 3, and the side deck 21.

According to the deck structure for a small boat having the above configuration, even if the front deck 24 hits waves from the front,
Since there is a front surface 41 of the cabin 4 and a first wave shielding section 42, water hardly ever penetrates to the rear thereof, and the step section 25 can be kept dry in most cases. Even if water enters the step section 25, the second wave shield section 44 prevents water from entering the cockpit 23.
Water is drained from the side of the step section 25. and,
As can be seen in FIG. 5, which shows the portion V in FIG. 4 viewed from the back, each portion is smoothly continuous and has no narrow, convoluted areas, making it easy to perform reinforced plastic molding work.

FIG. 6 shows another embodiment of the present invention, in which the center part 44a of the second wave shield part 44 is lowered, so that when moving from the cockpit 23 to the step part 25, the feet do not get caught. It has the advantage of being easy.

FIG. 7 shows still another embodiment of the present invention, in which a step stool 23a is provided at a corner portion of the cockpit 23 close to the step portion 25. There is an advantage that when the step portion 25 is high, the user can easily move his body by placing his foot on the step stool 23a.

According to the deck structure for a small boat according to the present invention, the first wave shielding part and the second wave shielding part prevent water from entering the deck pit, and the step part is often dry, so that feet do not slip. It is safe, and the shape of the deck is smooth because coaming parts and drainage grooves are not required, which improves the workability of reinforced plastic molding, reduces man-hours, and provides good quality without bubbles or cracks. be able to.
