Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lifejacket worn on the body to prevent drowning.

[0002]

2. Description of the Related Art As is well known, in marine sports such as yachts, jet skis, windsurfing, and fishing on fishing boats and rocks, accidentally falling into the water or being swept away by the waves may occur. , Drowning may cause a water accident. Therefore, for the sake of safety, life vests are often worn in advance.However, even when the life vest is suddenly thrown into the water as described above, the body should be levitated and drowned. To prevent.

As shown in FIG. 4, as a conventional life jacket 21 of this type, a vest-shaped one having a back part 2, a left front part 3 and a right front part 4 is known. The left front part 3
The right front part 4 is connected at its upper end to the upper end of the back part 2 by a shoulder connecting member 7, and at one side end thereof is connected to the side end of the back part 2 by a side connecting member 8. . The other ends of the left front part 3 and the right front part 4 can be locked by a locking member 9. Further, the reflection sheet 1 is provided above the back portion 2, the left front portion 3, and the right front portion 4.
0 is attached to each.

As shown in FIG. 5, each of the back portion 2, the left front portion 3, and the right front portion 4 is composed of a surface material 14 and a synthetic resin foam 6 such as styrofoam. Inside, a plate-shaped synthetic resin foam 6 having a thickness t is provided.

[0005]

However, in the conventional life jacket 21 as described above, in order to ensure sufficient buoyancy, the synthetic resin foam 6 provided therein has a thickness t of 3 to 4 cm. Thick ones are used. Therefore, because of this thickness, the synthetic resin foam 6 is less likely to bend, and the life jacket 21 in which the synthetic resin foam 6 is installed does not fit the contour of the body and is uncomfortable to wear. There is a problem that it is difficult to move the body.

Further, since the thick synthetic resin foam body 6 is provided inside, the life jacket 21 is very bulky, which makes it uncomfortable to wear and to store and transport it. However, there is a problem in that it lacks convenience.

Further, since the synthetic resin foam 6 has a flat plate-like shape, the inside of the life jacket 21 and the body are in close contact with each other via the surface material 14, and the breathability is poor, which causes discomfort. There is a problem.

The present invention has been made in view of the above problems, and is compact and highly convenient when not worn, adjustable in buoyancy when worn, and adapted to body movements. The purpose of the present invention is to provide a life jacket that is comfortable to wear.

[0009]

Means for achieving the above-mentioned object is, firstly, a vest-shaped life jacket having a back part, a left front part and a right front part, said back part being Inside the left front part and the right front part, an air mat with an adjustable air volume, which is divided into a plurality of air chambers, is installed internally, and the back, left front part, and right front part are each made of synthetic resin foam. Has been installed internally. Second, in the air chamber of the air mat installed inside the back,
The air chambers of the air mats provided inside the left front part and the right front part are connected by connecting pipes. Third,
An air pump for supplying air to the air chamber of at least one of the air mats is detachably connected. Fourthly, a holding member capable of holding the air pump is attached at a predetermined position.

[0010]

According to the first means, air mats with adjustable air volumes are provided inside the back, left front, and right front of the waistcoat-like life jacket, and synthetic resin is provided inside each. Since the foam is provided internally, when air is supplied to the air mat to fill it, the air mat itself also has buoyancy, which allows the thickness of the synthetic resin foam to be reduced. In this case, the thickness of the synthetic resin foam is such that if the air mat is accidentally dropped into the water without being filled with air, or if it is dropped into the water while it is filled with air, then the air mat may be damaged due to some cause. Even if the air comes out due to sticking or the like, it is sufficient that the body can float above the water. In this way, if the synthetic resin foam is made thin, the synthetic resin foam is easily bent, and the air mat is divided into a plurality of air chambers and is flexible, so that it fits the contour of the body. It becomes easy to move the body.

Further, when not worn, if the air is removed from the air mat, the back portion, the left front portion, and the right front portion are thinned, so that the life jacket becomes very compact. Since the air capacity of the air mat can be adjusted, the buoyancy can be adjusted. Furthermore, since the air mat is divided into a plurality of air chambers, its surface has irregularities, but this is the back, left front,
And because it is installed inside the inside of each right front part,
A space will be formed between the body and the body. In this case, if a surface material having air permeability is used as the surface material enclosing the air mat or the synthetic resin foam, even if the surface material and the body are in close contact, the space between the body and the air mat is small. Since the space is formed, the air permeability is further improved.

According to the second means, the air chambers of the air mats provided in the back are connected to the air chambers of the air mats provided in the left front part and the right front part by connecting pipes. Therefore, if air is supplied to one of the air mats to fill it, the air is also sent to the other air mats.

According to the third means, since the air pump for supplying air to the air chamber of at least one of the air mats is detachably connected, the life jacket can be optionally worn while wearing the life jacket. At that time, air can be supplied to perform the filling. Also, as described above, connect the air chambers of the left front air mat and the air chambers of the right front air mat to the air chambers of the back air mats respectively, and connect the air pump to the air chamber of one of the air mats. In this case, one air pump connected to the air chamber of one air mat can supply and fill all the air mats with air. If an air pump is connected to each of the air chambers of two or more air mats so that air can be filled at the same time, the air filling time can be shortened. Here, since the air pump is detachably connected, it can be removed when it is unnecessary, such as an obstacle after air filling.

Furthermore, according to the fourth means, since the holding member capable of holding the air pump is attached at a predetermined position, the air pump can be held in close contact with the life jacket and out of the way.
