Abstract

<P>PROBLEM TO BE SOLVED: To provide flexible clothing making movement of wearers easy and having adequate buoyancy. <P>SOLUTION: The separation type swimsuit 1 as one example of clothing is composed of west 2 and pants 3 and several belt-like pockets 4 in the vertical direction by the lining fabric are each formed in the both of these west 2 and pants 3 and several thin strip-like buoyancy sheets 5 each made of low-density polyethylene are inserted in superposed state in each of these pockets 4. Since the swimsuit 1 has buoyancy wholly, whole the body floats with adequate buoyancy by only wearing the swimsuit 1. Since the swimsuit 1 just fits the body and the buoyancy sheet 5 is soft, the wearer is very movable and the swimsuit 1 does not prevent swimming. As a result, physically-handicapped persons, aged persons and nonswimmers can receive underwater rehabilitation and swimming lesson without anxiety. Since the buoyancy can finely be adjusted by adjustment of the numbers of the buoyancy sheets, the swimsuit 1 does not cause excessive floating and the swimsuit 1 is appreciated also in children's swimming schools. <P>COPYRIGHT: (C)2003,JPO

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to clothes (including underwear, outerwear, swimwear, life jackets, etc.).

[0002]

2. Description of the Related Art At presently active swimming schools, a swim helper with a floating ring attached to the upper arm and lower back is used exclusively as an auxiliary tool. On the other hand, for people with weakness such as physically handicapped persons and the elderly, a helper with only arms has a feeling of fear, and there is a high demand for those who can float the whole body with appropriate buoyancy. However, with the type that inflates with the air as it is today, if you make it a type that covers the entire upper body, you will not be able to talk because it will float too much and you will not be able to move.

At present, life jackets are
Although it refers to a waistcoat type that is inflated with air, these are generally stiff and inflexible, and have the drawback that they become difficult to move when attached. Therefore, fishermen and others hate to wear them, and as a result, there are many accidents such as loss of life in a distress.

The present invention has been devised in view of the above background, and provides a garment which is flexible, easy to move, and has an appropriate buoyancy.

[0005]

The garment of the present invention is characterized in that a sheet-shaped low density polyethylene is attached. By attaching a sheet of low-density polyethylene that does not absorb water, it can be attached to a body that is highly flexible and fits the body, making it very easy to move. Also, low-density polyethylene is used for several millimeters to 0. It is possible to adjust the buoyancy by making a sheet with a thickness of several millimeters and adjusting the number of sheets. As such low density polyethylene,
The one in Korean Patent No. 46033 is the most suitable. The low-density polyethylene produced by the method of the patent does not absorb water,
It also has excellent buoyancy.

The method of attaching the low-density polyethylene can be sewn or attached to the inside or outside of the garment, or a pocket can be placed in an appropriate place of the garment and inserted. Considering the buoyancy adjustment depending on the number of sheets, it can be said that the method of making pockets and inserting them is suitable.

[0007]

1 shows an example of a swimsuit.

The swimsuit 1 of this example is a separation type,
It consists of vest 2 and pants 3. In both of them, vertical strip-shaped pockets 4 are formed at several places by the lining,
In each of the pockets 4, several buoyancy sheets 5 of low-density polyethylene in the form of strips are stacked and placed. The number of stacked sheets (three sheets in the illustrated example) can be increased when the buoyancy is desired to be increased, and can be decreased when the buoyancy is desired to be decreased, so that the buoyancy can be adjusted to an optimum state according to the application. . The mouth of each pocket 4 may be closed with a surface fastener or an ordinary fastener, or may be sewn if the buoyancy sheet 5 does not have to be taken out later.

In this swimsuit 1, since the swimsuit itself has buoyancy, the entire body floats with an appropriate buoyancy just by wearing it. And since it fits perfectly to the body and the buoyancy sheet 5 is flexible, it is very easy to move and does not interfere with swimming. Therefore, even persons with disabilities, the elderly, and people who are completely obliged to take underwater rehabilitation and lessons can feel at ease. In addition, since the buoyancy can be finely adjusted partially depending on the number of buoyancy sheets 5, it is useful for children's swimming classes and the like without floating too much.

Along with this swimsuit 1, a belt-like swim helper 6 to be wrapped around the waist as shown in FIG. 2 can be made with the same structure. The helper 6 is used by wrapping it around the waist and stopping it with the hook-and-loop fastener 7 so that the buoyancy sheet 5 comes to the back side. Even when such a helper 6 is used, the buoyancy can be appropriately adjusted by adjusting the number of buoyancy sheets 5 to be loaded, and the buoyancy can be selected according to the physique and weight.

As a further example, FIGS. 3 and 4 show an example of a raincoat.

The raincoat of this example is a separate type of outerwear 10 and trousers 20, which has a high heat insulating effect, and is cold and waterproof.
It exerts the function of buoyancy and also functions as a life jacket. Therefore, it is suitable for fishing, work inside refrigeration / freezer, outdoor work in cold regions, mountain work, fishing, and motorcycles.

First, this raincoat outerwear 10 has a lining on the entire inner side, and a buoyancy sheet 12 made of sheet-like low density polyethylene is inserted into a pocket 11 formed by this. . That is, jacket 10
The buoyancy sheet 12 is inserted as a whole. Since the thickness of the buoyancy sheet 12 is about several millimeters, the buoyancy sheet 12 is thin and highly flexible, and is very fit to the movement of the body. Therefore, even if this jacket 10 is worn, it does not become bulky and hinder the work. Although the buoyancy sheet 12 is not inserted in the arm portion in this example, it is of course possible to put it here.

On the other hand, the trousers 20 are of an overall type, and a rubber belt 21 is formed on the waist so that they fit to the body. And the breast pad 22 on it
The back support portion 23 is sewn into a bag shape to form a pocket, and the buoyancy sheets 24 and 25 are inserted in the pocket and sealed. In addition, both legs crotch 2 below the rubber belt 21
Similarly, 6 and 27 are sewn in a bag shape to form pockets, and buoyancy sheets 28 and 29 are inserted therein and sealed.

In the case of the pants 20 of this example, the crotch portions 26, 2
The buoyancy sheets 24, 2 contained in the chest support portion 22 and the back support portion 23 are more than those in the buoyancy sheets 28, 29 contained in 7.
5 is made thicker so that the breast rest 22 and the back rest 23 have higher buoyancy. As a result, the buoyancy of the upper body is stronger than that of the legs, and it is designed so that it does not become a handstand when floating in water.

Buoyancy sheets 12, 24, 25, 28, 29
Since it does not breathe water, it has a high waterproof effect, and since it does not let air flow, it has a high cold protection effect. In other words, it has excellent functions as a waterproof / cold protection device and also has sufficient buoyancy as a life-saving device, so it is the best alternative to a life jacket for fishermen. In addition to such applications, life-saving underwear to which a buoyancy sheet is attached can be applied, and a waistcoat-shaped life jacket may be made using the buoyancy sheet.

A buoyancy test was conducted on the raincoats of the forms shown in FIGS. 3 and 4. The test method is that when the inner air layer was removed, the upper and lower raincoats of this example were floated in fresh water, and iron pieces were hung to gradually increase the amount of iron pieces, and when they reached a completely submerged floating state. Was measured as the initial buoyancy. After that, the buoyancy was measured again after standing for 24 hours in the fully submerged state. As a result, the initial buoyancy of the jacket (mass 920 g) was 3.
7 kg, 3.7 kg after 24 hours, pants (mass 830
As for g), initial buoyancy is 4.9 kg and after 24 hours is 4.7.
It has a very good buoyancy and lasting power of kg.
