Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a rubber boat, and more specifically, to a rubber boat for going down a river.

(Prior Art) Recently, as the use of rubber boats to go down the river has become popular, rubber boats exclusively used for going down the river have started to be manufactured.

A rubber boat dedicated to river rafting in the rapids,
A drainage function that quickly drains a large amount of water that enters the ship, and maintains buoyancy when flooded,
Although ensuring the rigidity of the boat itself is required, there is currently no boat that reasonably satisfies these requirements.

(Technical Issue) The technical issue of the present invention is to provide a rubber boat with a high drainage function, and to improve buoyancy when submerged in water.
The objective is to ensure the rigidity of the rubber boat body in a reasonable manner.

(Means for Solving the Technical Problems) The means taken by the present invention to solve the above-mentioned technical problems is to configure the bottom of the rubber boat main body with an air mat, and to form the bow and stern parts of the rubber boat main body. It is tilted upward at a predetermined angle, and drain holes are provided in the bottom of the ship on both sides.

(Function) According to the above configuration, the bottom made of air mats increases the rigidity of the rubber boat body, and
Produces buoyancy when submerged in water.

Furthermore, water that enters from the bow and stern portions flows along the bottom surfaces of both portions and is quickly drained from the drain ports.

(Effects) As described above, in this invention, the bottom of the boat is constructed using an air mat that is much stronger than the conventional single-piece rubber sheet, so it is possible to increase the rigidity of the rubber boat body and also The bottom of the ship can provide sufficient buoyancy during flooding.

In addition, a large amount of water enters the rubber boat, especially from the bow and stern parts, but the water that has entered can be quickly drained from the drainage holes while flowing along the bottom of the bow and stern parts that slope upward.
It is capable of descending through torrential currents with a lot of water intrusion without any trouble.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

The rubber boat body A is a canoe-shaped rubber boat, and has a relatively long pneumatic cylinder 2 in the overall length direction, and a pneumatic cylinder 2 that is relatively long in the overall length direction.
The ship bottom 1 covers the bottom surface of the ship.

Air cylinder 2 is the right air cylinder 2 that constitutes the right half of the air cylinder.
a and a left air cylinder 2b forming the left half.
Both cylinders 2a and 2b are formed by bending and tilting the bow and stern parts upward at a predetermined angle, and
They are connected at the transverse air cylinders 2c', 2c, 2c', which serve as the passenger's seats, and are fixed by abutting the front and rear ends against each other. In addition, there are seat covers 4 on the bow and stern tops.
4 and by covering the bottom of the bow and stern with rubber sheets, a bow inclined surface 5 and a stern inclined surface 5 which are inclined against the curved upward portion of the air cylinder 2 are formed. Drainage holes 3 are opened on both inclined surfaces 5,5.

The drainage hole 3 has a diameter of about 5 cm, and is located at the lowest position of both the inclined surfaces 5, 5, which are the horizontal air cylinders 2c', 2.
8 to 10 holes are formed in the warped part of c′ and in the part along the right and left air cylinders 2a, 2b, which will be the flow paths for the infiltrated water, and a ring-shaped stopper 3a is fitted and fixed on the edge of the hole. This prevents the rubber sheet from tearing from the three holes.

The bottom 1 of the parallel part of the air cylinder 2 is composed of an air mat having a substantially rectangular plane, and its periphery is surrounded by the horizontal air cylinders 2c',
2c' and the parallel part of the air cylinder 2 firmly.

Rigidity of the rubber boat main body A constructed as described above is ensured by the air body 2 and the bottom 1 consisting of an air mat, and when a large amount of water enters the boat, the bottom 1 has sufficient buoyancy. occurs, so
It does not sink excessively even when flooded, and can descend through rapids without difficulty.

As the rubber boat sways violently vertically as it descends on the rapids, a large amount of water enters the boat from the bow and stern. Water that has entered from the bow and stern portions flows along the bottom of the ship, that is, along both the bow and stern inclined surfaces 5, 5, and is quickly drained out of the ship from the drainage holes 3. The size, shape, number, and opening position of the drainage holes 3 are arbitrarily determined depending on the flow path and amount of infiltrated water determined by the form of the rubber boat.

The rubber boat body A mentioned above has a canoe shape suitable for going down the river, and has reasonable rigidity, buoyancy when submerged in water, and drainage performance, so it can go down in strong currents without any trouble. It is possible.
