Description

A LIFE JACKET}

The present invention relates to a water-saving lifesaving, and more particularly, to provide improved life jackets worn during water leisure or water work, such as lifejackets, life jackets, lifejackets, while maintaining a high buoyancy while maintaining a high buoyancy. It is to help you achieve your purpose faithfully.

In general, lifesaving means distress while securing the safety of workers in life jackets worn for safety during water leisure activities, work on board for fishing or installation work for installation on rivers, lakes and seas. It is a generic term for life-saving suits that can save the lives of users (workers) by allowing them to be injured on the water.

The life preserver as described above is made in various forms such as a vest that can be worn by the user or a form such as clothes that are worn on a daily basis.Built-in buoyancy material enables the user to be injured on the water by buoyancy material even if the user falls into water. By maintaining it continuously, the user (distressed person) can continue his life for a certain time even if it is unconscious.

Various kinds of life preservers as described above have been developed and used, and are typically configured as shown in FIGS. 4 and 5.

The waterborne life preserver (1) to which the prior art is applied includes an endothelial (2) in contact with a user's body, an outer skin (3) located outside thereof, and a buoyant material (4) interposed between the inner skin (2) and the outer skin (3). It consists of.

The buoyancy material (4) is inserted into the buoyancy material space (5) formed by the inner shell (2) and the outer shell (3) to finish through sewing to complete the life preserver (1) such as a life jacket or life jacket.

In particular, the buoyancy material space (5) in the case of the back portion of the life vest so that the upper side and both sides in a fixed state through the sewing, only the lower side is placed in the open state buoyancy material (4) made the same shape as the back portion (4) After inserting), the opening part is closed, and in the case of the front part of the life jacket, the buoyant material (4) having the same shape as the front part is inserted in the state of fixing the upper side and both sides, and then sewing the opening part. Finishing through the life preserver (1) is completed.

In the prior art as described above, since the overall thickness of the buoyancy material usually has a thickness of 20 to 30 mm, the fabric constituting the buoyancy material and the life preserver cannot be fixed by sewing. Get drunk.

For this reason, even after the life preserver is completed, the buoyancy material is easily moved in the buoyancy material space, as well as the phenomenon that the buoyancy material is maintained in a different direction without maintaining the position occurs.

As the buoyant material is moved in a state separated from the life preserver in this way when the life preserver is in close contact with the body is impossible because the wear is not good, causing a decrease in activity.

This is because the buoyancy material is inserted into the PE foam (high foaming) material having a thickness of 10mm or more in the 2-3-ply buoyancy material space, and it is not possible to hold and integrate a plurality of layers of buoyancy materials, as well as to fix the buoyancy material and the inner and outer shells. It's also because you can't.

In addition, since the buoyant material is hard and hard, when the user wears it, the buoyant material and the body are in contact with each other, and friction occurs. As a result, the buoyancy force suddenly generated when the water is distressed generates a force to increase the lifespan. Being in the form of hitting the body, especially the neck of the person does not achieve the purpose of rescue rescue, but rather cause damage to the user's body.

In the process of using the life preserver, the buoyant material is repeatedly contracted and expanded in the process of repeated contact with water and drying, and the phenomenon of curling the end of the buoyant material is caused by this phenomenon, as well as It is impossible to carry out the normal functioning of the life preserver because it is caused by agglomeration in one direction.

The life savings to which the prior art is applied as described above are deteriorated in overall quality, which makes the external competitiveness vulnerable, as well as shortening the lifespan and deteriorating appearance as the use time elapses. .

In the present invention, to solve the problems described above, the buoyancy material composed of several sheets of thin foam sheet is wrapped with a covering material, protruding the edge of the covering material surrounding the buoyancy material to form a fixed blade, the fixed blade life preserver The inner skin and the outer skin constituting the right side is connected and then fixed by sewing, so that the buoyancy is excellent while improving the wearing comfort, it is possible to achieve the purpose of life preserver.

The present invention is close to the user's body when wearing a lifebuoy, while the buoyant material is not in a hard state while increasing the feeling of wearing, even when distressed in the water, it is possible to exclude the occurrence of dangerous situations, as well as periodic and long-term It is an invention having various effects, such as being able to prevent a phenomenon in which the buoyancy material is cut in one direction or the end is curled in order to maintain a uniform quality.

The life preserver 100 to which the technique of the present invention is applied wraps the buoyancy material 101 with the covering material 102, and the edge of the covering material 102 surrounding the buoyancy material 101 protrudes to fix the fixed blade 103. It forms integrally.

The fixed blade 103 is configured by fixing the inner shell 104 and the outer shell 105 constituting the life preserver 100 and then through the sewing 106.

The buoyancy material 101 is soft even to have a predetermined thickness (20 to 30 mm) by stacking a plurality of sheets of high foamed PE, low foamed PE or electromagnetic crosslinking (EVA) sheet having a thickness of 1 mm or less. It is preferable because it can last.

When the thickness of the buoyancy material 101 having a thickness of 1 mm or more was used, the overall stiffness was formed as in the case of using a buoyancy material having a thickness of 10 mm or more. It is not preferable because it is.

The buoyancy material 101 and the covering material 102 are sewn 107 to prevent the phenomenon that the plurality of buoyancy material 101 is separated from each other and to prevent the phenomenon that the edge portion is curled to maintain a stable shape continuously Good to do.

In addition, wrapping the buoyancy material 101 using the cladding material 102 has a purpose to solve this problem when sewing using only the buoyancy material 101 is impossible to supply to the sewing machine for sewing work by high friction force. .

The coating material 102 may be made of a fabric paper in which the buoyancy material 101 is completely enclosed, but considering the frequent contact with moisture due to the characteristics of the life preserver 100, it is easy to drain water and uses a mesh system having excellent dryness. It is desirable to.

The buoyancy material 101 is an antimicrobial treatment to exclude the occurrence of mold and odor that may occur in the process of repeated contact with moisture and frequent drying, and water repellent treatment to remove the adsorbed state if possible moisture is possible. It would be desirable.

When wearing the water-saving life preserver 100 to which the technique of the present invention is applied as described above, the following advantages can be obtained.

 The buoyant material 101 having a very thin thickness is wrapped with the covering material 102, and then the life preserver 100 is formed on the inside and the outside of the fixed blade 103 which is formed to protrude integrally at the edge of the covering material 102. After the inner shell 104 and the outer shell 105 are connected to each other, the life span 100 may be completed by fixing the covering 102 and the inner and outer shells 104 and 105 through the sewing 106.

The life preserver 100 completed as described above has the buoyant material 101 wrapped around the buoyant material 101 in a fixed state with the inner and outer shells 104 and 105, and the buoyant material 101 is also in a fixed state with the covering material 102. Even if the user moves in a worn state, the buoyancy material 101 does not flow or be pulled in any direction and the phenomenon of the edge portion is not rolled out, so the wearing comfort is excellent.

In addition, the buoyancy material 101 is composed of several sheets having a thin thickness even when moving in a worn state, so that the air layer existing between each of the buoyancy material 101 and the buoyancy material 101 does not cause rough feeling or damage even when closely attached to the body. By this, the buoyancy is increased further.

In addition, by performing antibacterial or water repellent treatment on the buoyancy material 101, even if the water and frequent contact and repeat the wet state and dry state to eliminate the occurrence of mold and odor can maintain a pleasant and hygienic state, contact with moisture Even if it prevents the phenomenon that water is easily adsorbed to the buoyancy material 101, it is possible to achieve the original purpose of life preserver (100).
