Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a small watercraft equipped with a floating body as an auxiliary float and as a rescue swim bladder.

[Prior art and its problems] Small boats such as jet-propelled small personal watercraft have slim hull shapes in order to enjoy high-speed running and sharp turns.

Therefore, it is difficult for beginners to maintain balance when running.

It is also difficult to maintain balance when boarding and when the ship is stopped.

On the other hand, if a small boat discovers a drowning person while sailing, even if it rushes to the scene, it is not equipped with a life-saving scent, so the only way to rescue the person is for the operator to jump into the water. At that time, loading the drowning person into a small boat is an extremely difficult task even for an experienced person because, as mentioned above, it is difficult to balance the small boat.

Traditionally, the means for balancing small boats are as follows:
Auxiliary float device for stabilizing small high-speed boats described in Japanese Patent Publication No. 59-43355 and U.S. Patent No. 3,369.51
The water vehicle shown in the specification and drawings of No. 8 has wings provided on both sides thereof.

However, these are only for the purpose of stabilizing the hull.
It is fixed to the hull and cannot be removed, making it impossible to set up an IQ for rescue purposes.

[Object of the Invention] The present invention has been made in view of the above-mentioned problems, and has the function of an auxiliary float so that the balance can be easily balanced as necessary when running a small watercraft. The object of the present invention is to provide a small boat equipped with a floating body having the function of a rescue swim bladder.

[Means for Solving the Problems] A small boat equipped with a floating body of the present invention to solve the above-mentioned problems has a floating body that is detachable or towable built into the hull at the position of the small boat hook. The floating body is characterized by having a structure that allows the floating body to be expanded and evacuated by a gas outside the hull, and then folded and contracted.

[Function] When a beginner boards the small boat, the floating body of the small boat constructed as described above can be used as an auxiliary float by taking it out of the hull and inflating it by injecting gas. This improves the stability of the vehicle, making it easier to board the vehicle. In addition, when a beginner navigates and navigates, by driving with the auxiliary float out, the rolling of the small boat is reduced, making it easier to maneuver. It is stable even when the ship is stopped roughly, so it is easy to handle.
It's easy to get off the ship.

In addition, if a small boat discovers a drowning person while sailing, it will rush to the scene, stop the boat, take the floating body out of the boat, inflate it with a gas injection, use it as a rescue float, remove it from the hull, and move it to the boat. If it can be towed, it will be towed toward the land where it was dropped and rescued by dropping it at the drowning person and letting them grab it. When using the floating body as an auxiliary float to rescue a drowning person, the auxiliary float can be used immediately as a rescue float in the same manner as described above, so it can respond quickly and is extremely effective as a lifesaving device.

If the floating body 8 is used as an auxiliary float 8' and goes to rescue a drowning person, immediately remove the auxiliary float 8' from the hull as a rescue float 8'' and aim it toward the drowning person. Drop it and rescue.

When the co-floating body 8 of each of the above embodiments is to be stored in the accommodation space 2°2' after use, it is preferable to loosen the threaded portion of the check valve 8a, vent the air, and fold it.

In each of the above-mentioned embodiments, when the floating bodies 8, 8 are used as rescue floats 8'', they are removed from the ship's hull, and when the gas cylinders 9 are dropped toward a drowning person, the rubber hose 10 of the gas cylinder 9 is removed from the floating bodies 8, 8. , one end of the towing lobe is placed in the accommodation space 2
, 2' to the hull, and the other end to the floating body 8.8, and attaching the rubber hose 10 to this towing lobe.
8 can be dropped towards a drowning person, and if the person clings to the floating body 8.8, the towing robe can be pulled to save the person, but it is also possible to attach it to the side of the floating body 8.8. . Further, the gas in the gas cylinder 9 may be air or other gas in addition to CO2 gas.

The shape of the rough floating bodies 8, 8 is not limited to that of the above embodiment, and may be ring-shaped.
The floating body may be inflated in two stages when used as an auxiliary float 8' and when used as a rescue float 8''.In that case, the shape of the floating body is changed to a boat with a concave cross section by two stages of inflation. In short, the floating body may have any shape as long as it can be used both as an auxiliary float and as a rescue float.

[Effects of the Invention] As can be seen from the above explanation, the small watercraft equipped with the floating body of the present invention can be used for boarding by beginners, for maneuvering and sailing, and for stopping by taking the floating body out of the hull and injecting gas to inflate it. By using it as an auxiliary float, the stability of the small boat is improved, making it easier to board the boat, less rolling, easier to maneuver, easier to handle when the boat is stopped, and easier to disembark. In addition, when a person is found drowning, the floating body is rushed to the scene and inflated, and while it is being used as an auxiliary float, it can be used as a rescue float, removed from the hull, and dropped towards the person to rescue the person. If you have one, you can grab it in a rescue swim bladder and pull it up.

Therefore, a small boat equipped with a floating body can contribute to improving the skills of beginners, and has the effect of increasing the IQ in rescuing drowning people.
