Description

[Detailed explanation of the invention] This invention consists of a U-shaped rubber tube hull and an FRP
This invention relates to the improvement of a composite small boat formed by combining a manufactured hull (bottom).

A composite boat, whose bottom is made of FRP (glass fiber reinforced plastic) and combined with an open-end U-shaped rubber hull (tube), does not impair its high-speed performance as a motor boat, and can be easily removed from the rubber hull during transportation. Because it can be deflated and folded into a compact size, it is attracting attention as a lightweight boat.

By the way, this boat has a transom board made of FRP that is integrated with the bottom of the boat and closes off the open end of the rubber hull so that an outboard motor can be attached. Conventionally, this transom board cannot be folded together with the bottom of the ship, so it gets in the way when the rubber hull is crushed and transported. In particular, when using a long-range outboard motor, which is common among outboard motors, a transom board with a height of about 50 cm is required, so it is difficult to transport it on the roof of a car. cause trouble. Therefore, from the viewpoint of transportation handling, it is preferable that the transom board be lower. However, the transom board cannot be made lower because it must improve propulsion efficiency when a long-range outboard motor is attached and must prevent flooding. Therefore, there is a need for a transom board that has a structure that allows it to be raised when the boat is in use and lowered when transported.

The present invention is in response to the above-mentioned demands, and
To provide a composite small boat whose transom board height can be changed during use and transportation.

The structure of the present invention to achieve such an object is a composite small boat that combines a U-shaped rubber tube hull and an FRP hull bottom, and the transom board is a fixed transom board integrally molded with the hull bottom, and a removable sub. The transom board is formed by dividing it into two parts, while a supporter is glued to the rubber hull to sandwich both side edges of the transom board to form a watertight structure, and the fixed transom board is joined to the supporter. The sub-transom board is connected to the fixed transom board by interposing an H-shaped waterproof packing between the upper end of the fixed transom board and inserting both side edges into the supporter.

The configuration of the present invention will be described in detail below based on an embodiment shown in the drawings.

FIG. 1 shows a perspective view of an embodiment of a small composite boat according to the present invention. This composite boat is
This boat is constructed by combining an FRP hull (hereinafter referred to as the bottom) 1 and a U-shaped tubular rubber hull 2, and has both the high-speed performance of a motor boat and the lightness of a rubber boat. As shown in FIG. 2, the bottom 1 and the rubber hull 2 are connected via a supporter 4 to prevent water from entering. That is, by inserting the edge of the bottom 1 in close contact with the groove 5 of the supporter 4 glued to the hull 2 side, and fastening with stainless steel bolts 6 and nuts 7 passing through these, the bottom 1 and the hull 2 are connected. is connected to. The bolts 6 and nuts 7 that connect the supporter 4 and the bottom 1 are tightened using aluminum flat bars 8 and stainless steel washers 9 in order to distribute the tightening load and provide decoration, and to prevent the tightening force from loosening. There is. The supporter 4 is a joint between the ship's bottom 1 and the ship's hull 2, and also acts as a packing to prevent water from entering the ship's bottom 1, so it is generally made of flexible and waterproof material such as rubber or synthetic resin. formed by.

A transom board 3 is provided at the rear of the boat to close off the open end portion of the hull 2 to define the inside and outside of the boat, and to which an outboard motor (not shown) is mounted. This transom board 3 is a fixed transom board 3a integrally formed with the bottom 1.
The fixed transom board 3a and the free sub-transom board 3b are assembled into an H-shaped packing 1.
0 to obtain the desired height. The sub-transom board 3b is preferably made of FRP like the fixed transom board 3a, but is not limited to this, and may be made of a material that is lightweight and rigid enough to support the outboard motor, such as an aluminum alloy. It's okay. Since the H-shaped packing 10 must connect the fixed transom board 3a and the sub-transom board 3b and prevent water from seeping in between them, it must be made of water-impermeable material that can tightly adhere to each transom board 3a, 3b. It is made of an elastic body such as rubber or synthetic resin.

In this embodiment, the H-shaped packing 10 is integrally molded with a supporter 4 that fixes the transom board 3 to the rubber hull 2 in order to improve the waterproof effect. Of course, the H-shaped packing 10 is the supporter 4.
It is also possible to provide it separately. As mentioned above, the supporter 4 is interposed between the rubber hull 2 and the FRP hull 1 to connect them, and is glued to the lower part of the hull 2 so as to cover the entire periphery of the hull 1. ing. Both ends of the supporter 4 are bent inward in the circumferential direction of the cylindrical hull 2, and are provided so as to fit with both side edges of each transom board member 3a, 3b. Both side edges of the fixed transom board 3a are inserted into the grooves 5 of the supporter 4 and adhered, and fixed to the rubber hull 2. Further, both side edges of the sub-transom board 3b are simply inserted into the grooves 5 of the supporter 4, and are clamped and fixed by the supporter 4, which has a U-shaped cross section, without being bonded.

The connection relationship between the fixed transom board 3a and the sub-transom board 3b is the outboard motor mounting seat plate 1.
1 on both the front and back sides. The outboard motor mounting seat plate 11 is arranged so as to straddle the fixed transom board 3a and the sub-transom board 3b, and
are fixed to each other with screw fasteners 12. Although not shown, this seat plate 11 is equipped with an outboard motor (not shown).
is installed.

Note that the outboard motor mounting seat plate 11 is used not only to reinforce the transom board 3, which is made up of two parts connected together, but also to suppress the free vertical movement of the sub-transom board 3b. Board 11
If not using sub transom board 3b
It is preferable to provide means for preventing vertical separation of the transom boards 3a and 3b, for example, a connecting member (not shown) that connects both transom boards 3a and 3b to each other.

As is clear from the above explanation, the composite small boat of the present invention has a U-shaped rubber tube hull and
In a composite small boat combined with an FRP hull bottom, the transom board is formed by being divided into two parts: a fixed transom board integrally molded with the hull bottom and a removable sub-transom board, and both side edges of the transom board A supporter having a watertight structure by sandwiching the parts is bonded to the rubber hull, and the fixed transom board is joined to the supporter, while an H-shaped waterproof packing is interposed between the supporter and the fixed transom board, and Since both side edges are inserted into the supporter and the sub-transom board is connected to the fixed transom board to form one transom board,
The height of the transom board can be changed freely by attaching and removing the sub-transom board, making it easy to transport.
