Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inflatable boat for rescue boats, and in particular, it is easy to lift a rescued person.
Moreover, the present invention relates to an inflatable boat for rescue boats that can be quickly operated.

[0002]

2. Description of the Related Art Conventionally, a normal air boat has been used as a rescue boat. However, in a normal air boat, a bottom cloth made of rubberized cloth is attached to the lower part of a substantially U-shaped body, and It consisted of several hard bottom plates, and in order to rescue the drowning person, the drowning person had to be pulled up from the side body. That is, the rescuer must pull up the drowning person from the inside of the ship onto the torso, and then lower it into the ship.To pull the drowning person up onto the torso, Because of the shape, it requires a great deal of force, and the body of the person being rescued must be bent or bent along the torso, and it takes time to pull up. It was

Furthermore, since the boat bottom structure is not solid, the rescuer's footing is poor, and during the rescue operation, the body of the body easily sinks below the water line and is easily flooded.
Rescue work was difficult. If rescue is not performed as quickly as possible, it may be the result of the life of the person being rescued, and the life may be lost due to the time required for the rescue. Therefore, the airboats that are commonly used as rescue boats that compete for size are inappropriate.

Therefore, in the air boat having a double body in which another body is overlaid on the body, the lower body has a buoyancy so that the thickness (diameter of the body) of the lower body is increased. Refer to an air boat that is made slightly smaller and forms a part of the side fuselage only from the lower fuselage (forms a portion where the upper fuselage does not exist), and reduces the diameter of the lower fuselage to reduce the upper fuselage. We examined an airboat in which the diameter of the ship was increased and the buoyancy was secured by the upper body, and a part of the side body was formed only from the lower body (where the upper body did not exist).

[0005]

However, in the above-described double-air-body air boat, the smaller the diameter of the lower body, the quicker and easier the rescue becomes. However, if the diameter of the lower fuselage is reduced to a certain extent or more, the water line will be located above the lower fuselage, and there is a chance that it will be flooded from there during running or during rescue work. There is a drawback that it is more than a normal air boat, and it can only be made a body with a diameter slightly smaller than the diameter of the body used for conventional air boats, and it can improve the drawbacks of conventional air boats regarding lifting of rescue recipients. No one could get a valid rescue boat.

The present invention has been made in the background of such a conventional technique, and the rescuee can be pulled up into the rescue boat as quickly as possible, and the rescue work can be performed in an extremely short time. Another object of the present invention is to provide an inflatable boat for rescue boats, which is unlikely to be flooded when traveling.

[0007]

In order to achieve the above object, the present invention provides a rigid hull 2 having an upright wall W integrally formed at a peripheral edge thereof with a body for imparting buoyancy thereto. An inflatable boat (1) having a structure provided along an outer surface of W, comprising a substantially U-shaped front body (3) having the body attached to the front part of the boat and two sterns attached to both sides of the stern. The hard hull 2 is provided with the U-shaped front body 3 attached to the front of the hard hull 2, and the stern of the hard hull 2 is spaced apart from the rear end of the front body 3. The stern air bodies 4, 4 are attached to the port side, and an opening portion 5 where no air body exists is provided between the front air body rear end portions 3a, 3b and the respective stern air body tip portions 4a. When the maximum load of an inflatable boat is loaded over the entire upper edge of the wall W Characterized in that protrude above the water line P

[0008]

According to the inflatable boat for rescue boats of the present invention, since there are the opening portions 5 on both sides of the rigid hull 2 which are not provided with the body of the body, the rescue recipient can easily enter the boat. Can be raised. Further, the rigid hull 2 has a standing wall W on its periphery, and the upper edge of the standing wall W is projected over the entire circumference thereof above the waterline P when the maximum load of the inflatable boat is mounted. , No water will be inundated while driving or during rescue work.

Explaining the operation of this embodiment, the front body 3 and the stern bodies 4, 4 are attached to the rigid hull 2 with a distance therebetween, and the opening 6 where no body is present is provided in the inflatable boat 1. Since it is formed on both sides, it is possible to easily and quickly rescue the person to be rescued (such as a drowning person). In addition, the water line P when the maximum load assumed on the inflatable boat 1 is applied is lower than the upper edges of the standing wall W and the rear plate 8, and therefore,
Even when the vehicle is running, the water does not enter from the opening portion 6, and the water that enters from the joint between the support bodies at the lower ends of the bodies 3 and 4 and the hard hull 2 reaches the upper end of the standing wall W. There is no. Therefore, the support and the horizontal plate portion 1 of the standing wall W are
0 or the lower outer plate portion 12 is joined by a relatively rough joint structure using no caulking material or the like, there is no risk of water ingress into the boat, and the number of screw members can be reduced.
