DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a bamboo boat. More specifically, the present invention relates to a bamboo boat that is easy to dispose and recycle, has excellent strength, is lightweight and inexpensive, and does not require resource depletion. In addition,
In this specification, the term “boat” is a broad concept including a rowing boat used in an amusement park or the like, to a small or medium-sized ship having an engine room.

[0002]

2. Description of the Related Art In recent years, demand for boats such as yachts and fishing boats (hereinafter referred to as "boats") has been increasing along with the increase in leisure and public awareness of leisure. Such boats have conventionally been mainly made of F from the viewpoints of workability, rigidity and heat resistance.
Made of RP (fiber reinforced plastic) or wood.

[0003]

However, the FRP
Although they cannot be incinerated even when they are abandoned, they are crushed and then buried in landfills. However, since this is troublesome and costly, many boats are left untreated, and its treatment is a problem. Further, although FRP has some strength, it has a fragile surface that is broken as soon as the ship's side hits a rock corner or the like.

[0004] In view of the above circumstances, an object of the present invention is to provide a bamboo boat which is easy to dispose and recycle and has excellent strength.

[0005]

The bamboo boat according to the present invention comprises:
It is characterized in that it consists of a hull made by press-forming a mixture of bamboo chips mixed with a binder at high temperature and pressure. The hull is preferably composed of an upper hull and a lower hull, and the upper hull and the lower hull are preferably composed of a plurality of members that can be divided in the longitudinal direction of the hull.

[0006]

The bamboo boat of the present invention is mainly made of bamboo chips, so that it can be easily incinerated or recycled, and has high strength and light weight.

[0007]

Next, a bamboo boat according to the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is an explanatory side view of an embodiment of a bamboo boat according to the present invention. In FIG. 1, A is a bamboo boat according to one embodiment of the present invention, and a hull 1 of the bamboo boat A has an upper hull 1a and a lower hull as shown in FIGS. 1b. Hull 1
An engine room 2 is provided at substantially the center of the boat A. A boat A moves forward and backward by rotation of a propeller 4 at the tip of a propeller shaft 3 connected to a main engine (not shown) in the engine room 2. . Note that an outboard propulsion device may be attached instead of providing the engine room 2. The direction change of the boat A is performed by operating the rudder 5 attached to the stern. Inside the hull 1, spaces such as a container 6 and a live fish storehouse 7 are provided as needed. Reference numeral 8 denotes a bone for reinforcing the hull, and is provided at a plurality of positions as necessary. Of the above-described configurations, the engine room 2 and the like other than the hull 1 can adopt ordinary ones, and are not particularly limited in the present invention.

A feature of the present invention resides in that the hull 1 is manufactured by press-molding a mixed material obtained by mixing a binder with bamboo chips at a high temperature and a high pressure. Bamboo chips
The bamboo material is processed into small pieces, minute pieces or cotton by grinding or cutting. For such bamboo processing,
A known processing device such as a chipper can be appropriately used. In this specification, “bamboo chip” includes all pieces of bamboo processed into small pieces, minute pieces, or cotton by crushing, cutting, or the like. Among the bamboo chips mentioned above, cotton-like ones can smooth the surface of the hull and provide an excellent tactile sensation, as well as reduce the water resistance and increase the speed of the ship. This is preferable because it can be achieved.

[0009] Bamboo chips are mixed with a binder, and the obtained mixture is press-molded at high temperature and high pressure. As the binder, any adhesive, resin, or the like may be used as long as the bamboo chips can be bonded to each other. For example, a urethane adhesive, a urea resin, a phenol resin, or the like can be used. The binder is mixed with bamboo chips,
The mixed material obtained by mixing with a known mixer or the like is filled in a mold having a predetermined shape, and is subjected to press molding at high temperature and high pressure. At this time, the size and shape of the hull to be manufactured can be freely set according to the size and shape of the mold used.

Next, a method of assembling the hull manufactured by the method described above will be described. A small boat with a relatively simple structure, such as an amusement park boat, can be made by pressing the entire hull in a single press.However, the size of a small boat class such as a fishing boat equipped with an engine room is large. Therefore, it is preferable to divide the hull into a plurality of parts to make the hull from the viewpoint of productivity and the like. In the boat shown in FIG. 1, the hull 1 includes the upper hull 1a and the lower hull 1b as described above (see FIG. 2). The upper hull 1a and the lower hull 1b are manufactured by separate molds and are integrated using bolts and nuts as shown in FIG. Sealing is performed between the upper hull 1a and the lower hull 1b by injecting a sealing material or sandwiching a packing. Instead of the bolt and the nut, an adhesive may be used to integrate the two hulls. Further, an appropriate means may be used for sealing the bolt.

In the embodiment shown in FIG. 4, an upper hull 11a and a lower hull 11b are divided into three in the longitudinal direction of the hull. By dividing the hull in the front-rear direction in this way, it is possible to cope with a certain size increase. Connection and sealing between a plurality of hulls can be performed in the same manner as in the embodiment shown in FIGS. Note that the number of divisions in the front-rear direction is not limited to three, and may be two or four or more.

[0012]

As described above, since the bamboo boat of the present invention uses bamboo chips as its main material, the following effects can be obtained. Since it can be incinerated easily, disposal is easy. In addition, if the abandoned ship is crushed, it can be molded again with a mold, so that recycling is possible. Therefore, a reduction in the number of abandoned vessels can be expected, and even if there is some measure, it is easy to take measures. Bamboo fiber has high strength. Also, since bamboo is light, it is possible to make the hull and the like thicker than an FRP ship without increasing the hull weight. Therefore, it is possible to obtain a high-strength boat that does not easily break even when it hits a rock corner or the like. Since the bamboo is light, the weight of the hull can be reduced.
Along with this, the speed of the ship can be increased. Bamboo grows in a short time (about 2-5 years)
Prospering all over the world, stable supply is possible,
Since price fluctuations are small, mass production is possible without worrying about resource depletion. Since bamboo is inexpensive, the cost of the boat can be reduced. Since all of the bamboo material can be used as bamboo material chips, there is no waste in the material and resource saving.
