Description

[Detailed explanation of the invention] (Industrial application field) This invention is designed to prevent
This invention relates to a flood prevention device for a canoe that prevents a large amount of water from entering the hull of the canoe from the hatch and causing the canoe to sink.

(Prior Art) Canoes, which are a type of boat, are widely used not only for calm seas, rivers, and boat races, but also for thrill-seeking in rough currents and rapids of rivers. However, because these canoes are small and very light, and have a long, slender shape that allows for speed, they are prone to capsizing or overturning, and capsizing accidents are common in this industry.

However, when a canoe capsizes or rolls over, an expert has mastered the technique of using physical manipulation to restore the canoe to its original state even if it capsizes or rolls over.
Most operators are unable to do this and must evacuate from the canoe. Naturally, water flooded into the hull of the overturned canoe from the hatch, but it was extremely difficult for the escape operator to expel the large amount of water that had entered the entire interior of the hull on his own under such circumstances. As a result, the canoe was forced to sink.

(Problem that the invention aims to solve) However, in the past, there was no device that could easily prevent a large amount of water from flooding into the canoe's hull when the canoe capsized, so other measures were taken. Otherwise, a capsized and flooded ship had to be towed to the shore by one's own effort, which was not only extremely troublesome, but also sometimes threatened human life.

(Means for solving the problem) This idea was created in view of the above, and it is designed to easily prevent water from flooding inside the canoe when the canoe capsizes or rolls over, making it easy to restore the hull. It is.

This device will be described in detail below with reference to the drawings. First, 1 is a canoe hull having a hatch 2 on its upper surface. Reference numeral 3 denotes a submergence bag whose upper opening is in close contact with the periphery of the hatch 2 and into which the lower body of the operator 11 can freely enter and take out (insertion and removal), and is made of, for example, flexible and waterproof polyethylene or polypropylene sheet. ing. The submergence bag 3 is normally stored inside the hull 1 as shown in the figure. Reference numeral 4 denotes a thin tube made of a flexible plastic material with a float 5 having an air hole 6 connected to one end.
As shown in Fig. 2, it is taken out of the ship and introduced into the flood bag 3 from the outside of the hatch 2, and the other end is passed through the tip of the bag and opened at the bottom of the ship's body 1 outside the bag. In the diagram, 7 is the seat, 8 is the backrest, and 9 is the seat.
is the spray skirt, 10 is the water surface, and 11 is the operator.

(Operation/Usage Conditions) If the canoe hull 1 capsizes due to rough waves or rapid currents while rowing the canoe in the condition shown in Figures 1 and 2, the operator 11 will be able to remove the hem of the spreskirt 9 automatically. You can easily jump out of the canoe and escape through the two holes. Then, of course, water will infiltrate only into the submersion bag 3 in the capsized canoe hull 1 as shown in Fig. 3, but in this case, the submergence bag 3
The amount of water that enters inside is small compared to the internal volume of the canoe, and if you pull the tube 4 that is fixed through the bag tip, the inside of the hull 1 will be filled with tube 4 and float 5.
Since it communicates with the outside air through the air hole 6, the submergence bag 3 can be easily pulled out from inside the hull 1 through the hatch 2 and the water inside the bag can be discharged. Therefore, the operator 11 who escaped into the water can easily restore the capsized canoe hull 1.

(Effect of the invention) Since this invented device has the above-mentioned configuration, even if the canoe hull 1 capsizes, the amount of water can be kept to a minimum from entering the flooding bag 3, and in particular, the inside of the hull 1 and the outside air can be kept to a minimum. Tube 4, which is constantly distributing
is attached to the tip of the submergence bag 3, so by simply pulling the tube 4 lightly, the water inside the submergence bag 3 can be easily drained, and the operator 11 in the water can easily restore the capsized canoe to its original position. It has an outstanding effect that can be restored. In addition, since the float 5 is connected to the other end of the tube 4, when the tube 4 capsizes, the position of the tube 4 can be easily confirmed by the float 5 floating in the water. It has excellent effects and allows for safe handling.
