Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a life jacket,
The present invention relates to a line used for a life-saving device such as a swimsuit and a life-saving flag, and a line used for a fishing line.

[0002]

2. Description of the Related Art Conventionally, life-saving devices such as life jackets are
A buoyancy body is attached to a fabric woven with synthetic resin yarn.

[0003]

A conventional life-saving device such as a life jacket has a buoyant body attached to a fabric. Therefore, when the buoyant body uses a foam material, it is bulky and inconvenient to carry. When the buoyant body is an air bag, there is a disadvantage that the air bag must be inflated at the time of use.

SUMMARY OF THE INVENTION In view of the above-mentioned drawbacks of the prior art, the present invention can be carried without being bulky, and can be used for a life-saving device or the like which can obtain a sufficient buoyancy without inflating with air when used. It is intended to provide.

Further, the present invention is capable of smoothly moving in and out and floating on the sea surface or the water surface, is lightweight and has sufficient strength, and can be partially used even if scratched and damaged during use. It is an object of the present invention to provide a line that can be used as a fishing line that can be damaged.

The foregoing and other objects and novel features of the invention will become more fully apparent when the following description is read in conjunction with the accompanying drawings. However, the drawings are for explanation only, and do not limit the technical scope of the present invention.

[0007]

In order to achieve the above object, the present invention provides at least two or more hollow chambers which are made of a synthetic resin material and have a substantially uniform outer diameter and which are closed by partitions formed at predetermined intervals. Are sequentially formed, and the air or the gas having a specific gravity lower than the air filled in the hollow chamber of the yarn main body constitutes the yarn.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the embodiments shown in the drawings.

In the first embodiment of the present invention shown in FIGS. 1 to 9, reference numeral 1 denotes a yarn of the present invention, and this yarn 1 is a synthetic resin material such as nylon, fluorocarbon, polyamide, or polyester and has an outer diameter. At least two or more blocks which are substantially uniform and are closed at intervals of 10 times or more of the outer diameter dimension, and at intervals of 20 times in the embodiment of the present invention, and 3 or more in the embodiment of the present invention. A yarn main body 4 in which the hollow chambers 3, 3, 3 are sequentially formed; and air filled in the hollow chambers 3, 3, 3 of the yarn main body 4, or a gas such as hydrogen gas or helium gas having a specific gravity lower than air. 5 is comprised.

When the line 1 having the above structure is used as a fishing line,
Since the outer diameter is formed to be substantially uniform, it can be smoothly pulled out and wound from the reel, and can be floated on the sea surface or the water surface for fishing as shown in FIG. In addition, since the three hollow chambers 3, 3, 3 closed with the partition walls 2 formed at a predetermined interval are filled with air or a gas 5 having a specific gravity lower than air, the yarn main body 4 is filled with three yarns. Even if a part of the yarn main body 4 forming the hollow chambers 3, 3, 3 is flawed, only the water enters the hollow chamber 3 of the part and becomes heavy, and the other hollow chambers 3, 3 maintain a hollow state. And can be used without significant impact.

The yarn 1 having the above structure can be processed into a fabric 6 used for a life-saving device or the like as shown in FIG. 5, and using the fabric 6 used for the life-saving device or the like as shown in FIG. Life jacket 7, swimsuit 8 as shown in FIG. 7, and sheet 9 as shown in FIG. 8 can be sewn to sheet 9 serving as a floating bag by rolling, and air as shown in FIG. A life-saving flag 12 in which a long string 11 is attached to a cloth 10 formed in the shape of a flag using a thread 1 used for a life-saving device or the like using the gas 5 floating inside may be used.

[0012]

FIG. 10 to FIG.
Hereinafter, different embodiments of the present invention will be described. In the description of the different embodiments of the present invention, the same components as those of the first embodiment of the present invention are denoted by the same reference numerals, and duplicate description will be omitted.

The second embodiment of the present invention shown in FIGS. 10 to 12 is mainly different from the first embodiment of the present invention in that three hollow chambers 3 formed in a yarn main body 4 are provided. ,
In the point that the partition walls 2, 2, 2 of the third and the third are formed at different positions, even with the yarn 1A thus configured, the same operation and effect as those of the first embodiment of the present invention can be obtained. And at the same time, the adverse effect when a part is scratched can be suppressed.

The third embodiment of the present invention shown in FIGS. 13 to 15 differs from the first embodiment of the present invention mainly in that four hollow chambers 3, 3 3,
3, the same effect as that of the first embodiment of the present invention can be obtained, and the four hollow chambers 3, 3, 3, 3 can be obtained. The thread-shaped main body 4 can be reliably prevented from being crushed by the cross-shaped side walls 3a, 3a, 3a, 3a that form.

The fourth embodiment of the present invention shown in FIGS. 16 to 18 is different from the first embodiment of the present invention mainly in that two hollow chambers 3, 3 And the yarn 1C having such a configuration in that the hollow chambers 3 and 3 are filled with a gas 5A such as colored air or colored helium gas. The same operation and effect as those of the embodiment can be obtained, and the color is changed when the gas 5A in the hollow chambers 3 and 3 is released due to the flaw, and the flawed portion can be easily confirmed.

[0016]

As apparent from the above description, the following effects can be obtained in the present invention.

(1) At least two walls closed by a partition made of a synthetic resin material and having a substantially uniform outer diameter and formed at predetermined intervals.
Since the yarn main body is formed by sequentially forming the yarn main body in which at least one hollow chamber is formed, and the air or the gas having a specific gravity lighter than the air filled in the hollow main body of the yarn main body, the hollow main body can be floated in water or air. . Therefore, it can be used as a fishing line that floats on the sea or water,
By using it as a thread for fabrics for producing swimwear, life-saving flags, and the like, it is possible to obtain sufficient buoyancy without being light, light, and bulky, and to protect against cold.

(2) According to the above (1), at least two or more hollow chambers are formed in the yarn main body. Therefore, when a part is flawed, the whole hollow chamber with the flaw is punctured. The state can be efficiently prevented.
Therefore, even if some of the cavities are scratched and some of the cavities are in a punctured state, it can be covered by the buoyancy effect of the other cavities and can be used continuously.

(3) According to the above (1), since the hollow chambers are sequentially formed by the partition walls formed at predetermined intervals, even if the hollow chambers are flawed, it is ensured that water infiltrates entirely by capillary action or the like. Can be blocked. Therefore, it can be optimally used as a thread of a fabric for manufacturing a lifesaving device.

(4) According to the above (1), the yarn main body is filled with at least two or more hollow chambers, and the hollow chamber is filled with air or a gas having a specific gravity lower than air, so that a lighter yarn can be obtained. Therefore, by manufacturing a life-saving device such as a life jacket using this thread, the life-saving device can be worn by the user without feeling uncomfortable.

(5) Claims 2, 3, and 4 also have the above (1).
The same effect as (4) can be obtained.
