Each of the capsules containing gas can be made of a synthetic resin material, with an interior space closed, formed in it. The gas is sealed in the interior space.

The gas-containing capsule can be manufactured by forming the synthetic resin material to a predetermined shape, with the internal space therein, by means of blow molding or injection molding, followed by the injection of gas into the interior space, and the sealing of the interior space.

Examples of the synthetic resin material may include ethylene vinyl acetate.

The lining fabric and the cover fabric may intermittently join together, at points adjacent to the gas containing capsules, in lateral and vertical directions, so as to form the compartments.

The compartments can be formed between the lining fabric and the cover fabric, which are joined together in the central areas. Each of the central areas is defined by four adjacent capsules of the capsules containing gas.

The capsules containing gas may have an octagonal shape in cross section. Each of the gas-containing capsules has eight side walls, in which four side walls have a shorter side length; the four remaining side walls have a longer side length, and the four side walls having a shorter side length form the corners of the gas containing capsule.

The security garments may additionally include a plurality of through holes, which penetrate the lining fabric and the cover fabric in the central areas; each of which is defined by four adjacent capsules of the capsules containing gas.

Safety garments may include a lifejacket, in which the capsules containing gas act as a floating material.

Mode of the invention The above advantages and other advantages of the invention and of the operation of the invention, and the above objects and other objectives, which are achieved in putting the invention into practice, will become more apparent from the following description, taken in conjunction with the annexed drawings, which show exemplary embodiments of the invention.

The present invention will now be described more fully in what follows, with reference to the accompanying drawings, in which exemplary embodiments thereof are shown. However, in the following description of the present invention, detailed descriptions of known functions and components, incorporated herein, will be omitted when they can make the subject of the present invention unclear.

The lifejacket of the invention can be applied in various forms, such as a vest, a jacket, pants, a garment and the like. In terms of use, the lifejacket can be applied as a flotation device, which keeps a user afloat in the water; as an absorbing device blows, which protects the user's body against external impacts when the user is in exercise or walking on the ground, and other similar. That is, in this description the term "safety garments" is used as a concept that includes various types of protective equipment, which are in the form of a piece of clothing that a person can wear on their body. However, in the following description, the safety garments of the invention will be limited, for illustrative purposes, to the lifejacket, which is used as a flotation device to prevent an accident from occurring in the water, keeping the user afloat, in water.

Figure 2 is a perspective view showing a lifejacket according to an exemplary embodiment of the invention; Figure 3 is a perspective view of the gas-containing capsule, shown in Figure 2; Figure 4 is a sectional view of the gas-containing capsule shown in Figure 3, and Figure 5 is a perspective view showing variations of the gas-containing capsule of the invention.

In addition, Figure 6 is a schematic plan view showing the enlargement of a part of the lifejacket shown in Figure 2; Figure 7 is a schematic sectional view of the lifejacket, taken along line VII-VII of Figure 6, and Figure 8 is a schematic sectional view of the lifejacket, taken along line VIII-VIII of the figure 6 With reference to Figures 2 to 8, the lifejacket 100 of this embodiment includes a plurality of capsules 130 containing gas, in which the gas is sealed, and a fabric structure 110, which includes a lining fabric 111 and a cover fabric 112. The lining fabric 111 and the cover fabric 112 are bonded together to form a plurality of compartments S, in which the capsules 130 containing the gas are contained.

With reference to Figures 3 and 4, each capsule 130 containing gas is configured to form a closed internal space, in which the gas is sealed, in order to produce a certain amount of flotation. Examples of the gas sealed within the capsules 130 containing gas may include: air, nitrogen (N2) and the like.

As shown in FIGS. 3 and 4, the capsule 130 containing gas has an outline generally in the form of an octagonal column, with an octagonal cross-section. Thus, the octagonal structure of the gas-containing capsule 130 forms eight side walls 131 and 133, four of which, the shorter side walls 131, have a shorter lateral length L-; and the other four side walls 133 have a longer lateral length L2. The four side walls 131 having the shortest lateral length L2 form four corners of the capsule 130 containing gas. Consequently, as shown in Figure 6, it is possible to establish that the central areas C, which are defined by four adjacent capsules 130 containing gas, have a sufficient space, at the same time as the distance between the multiple capsules 130 containing gas, thereby providing bonding areas in which the lining fabric 111 and the cover fabric 112 are easily joined in a dotted pattern. However, the shape of the capsule 130 containing gas is not limited to this embodiment. As shown in Figure 6, the capsule 130 containing gas can have a variety of shapes, such as those of a flat ellipse, a rectangular column, a hexagonal column and the like. In addition, the size of the capsule 130 containing gas it may vary, depending on the design of the lifejacket 100 being used. The advantage is that the smaller the capsule 130 that contains gas, the better the feeling of wearing it. Although not shown in the figures, it is preferred that the corners of capsule 130 containing gas be rounded.

Capsule 130 containing gas from a material selected from synthetic thermoplastic resins, such as ethylene vinyl acetate (EVA), polyethylene (PE), polyethylene terephthalate (PET), polyvinyl chloride (PVC) and the like can be made. . In particular, considering that the life jacket 100 is a piece of clothing worn by a person, it is preferred that the capsule 130 containing gas be made of EVA, which is a low cost material but has excellent flexibility (softness), shock absorbent capacity and heat retention. The capsule 130 containing gas can be manufactured by forming a thermoplastic synthetic resin material to a specific shape having a closed internal space, by means of blow molding, molding by injection or other similar; by injecting gas into the enclosed space and sealing the enclosed space. Here it is more preferable that blow molding is used, in which the capsule 130 containing gas is manufactured by blowing air into it, instead of injection molding, taking into account that the capsule 130 containing gas has such a shape , which has a closed interior space.

As described further back, the gas-containing capsule 130 can serve as an excellent floating material in the life jacket 100, since it is made of a synthetic resin material and gas, which is sealed therein. Additionally, unlike foamed resin, such as polyethylene foam, capsule 130 containing gas does not lose buoyancy, even if it is left in water for a long time, since water does not penetrate inside it. Therefore, the capsule 130 containing gas can improve the reliability of the life jacket 100. Additionally, the capsule 130 containing gas has the advantage that it can produce a flotation that is greater than that of the foamed resin of the related art, when they both have the same volume.

With reference to Figures 2, 6 and 8, the fabric structure 110, which includes the lining fabric 111 and the cover fabric 112, is generally prepared in the form of a vest that a person can wear. The lining fabric 111 and the cover fabric 112 can be made of natural or synthetic fiber, preferably of waterproof or water resistant fiber, considering that the life jacket 100 is used in water. The multiple capsules 130 that contain gas are arranged in such a way that they are spaced from one another, between the lining fabric 111 and the cover fabric 112. The lining fabric 111 and the cover fabric 112 are joined together to form multiple compartments S, in those containing multiple capsules 130 containing gas. Specifically, each of the capsules 130 containing gas is contained in a corresponding compartment S, which is defined between the lining fabric 111 and the cover fabric 112, in order to prevent the capsule 130 containing gas, which is arranged between the lining fabric 111 and the cover fabric 112, it is dislodged from its position, so that the multiple capsules 130 containing gas throughout the life jacket 100 are evenly distributed.

Here, the multiple compartments S, in which the multiple capsules 130 containing gas are contained, are formed between the lining fabric 111 and the cover fabric 112, which are "connected to each other in the central areas C, which are defined by four gas-containing capsules 130. Specifically, the lining fabric 111 and the cover fabric 112 are joined together at four points, which are adjacent to the four corners of the capsules 130 containing gas, so as to form between they are the multiple compartments S. Here, the lining fabric 111 and the cover fabric 112 are sewn together, specifically, the lining fabric 111 and the cover fabric 112 are securely joined together by stitching several times a point of the fabric. central area C, which is defined by the four capsules 130 containing gas, adjacent.

As in the above, in the lifejacket 100 of this embodiment, the multiple compartments S in which the multiple capsules containing gas are contained, are formed by joining together the lining fabric 111 and the cover fabric 112, so that the lining fabric 111 and the cover fabric 112 are intermittently joined together at points adjacent to the capsules 130 containing gas, in the lateral direction and in the vertical direction. That is, the joint structure having a dot pattern is applied to the joint between the lining fabric 111 and the cover fabric 112, which form the multiple compartments S. Consequently, the life jacket 100 of this embodiment can improve the feeling of wearing it and increasing the freedom of movement of a user, thanks to its increased flexibility, since the capsules 130 containing gas, which are contained in the compartments S can be moved within a predetermined distance. Here, as described above, since the capsules 130 containing gas have an octagonal cross-sectional shape, it is possible to fix the central areas C, which are defined by four capsules 130 containing adjacent gas, so that they have sufficient space , at the same time decreasing the distance between the multiple capsules 130 containing gas; thereby providing binding areas in which the lining fabric 111 and the cover fabric 112 are Easily united in a dot pattern. Contrary to this embodiment, the joint between the lining fabric 111 and the cover fabric 112, which forms the multiple compartments S, can be made continuously by a joining structure having joining lines including, for example, lines of lateral and vertical junctions, surrounding capsules 130 containing gas.

Even when the joint between the lining fabric 111 and the cover fabric 112 for forming the multiple compartments S is effected by sewing, it can be obtained by fusion, by joining, by a method using a separate joining tool (not shown) , such as an eyelet, or other similar ones. Further, even if a capsule 130 containing gas is contained in a compartment S, in this embodiment, two or more capsules 130 containing gas may be contained in a compartment S.

As described above, since the gas-containing capsules 130, in which the gas is sealed, are used as the flotation material, the lifejacket 100 of this embodiment exhibits excellent flotation. The reliability of the lifejacket can be improved since water can not penetrate the flotation material, even if the user remains in the water for a long time.

Additionally, the lifejacket 100 of this embodiment employs a tie structure having a dot pattern on the lining fabric 111 and the cover fabric 112, which forms the multiple compartments S in which the multiple are contained. capsules 130 containing gas, so that the capsules 130 containing gas, which are contained in the compartments S, can move within a predetermined distance. This, as a result, can increase the flexibility of the life jacket, improve the feeling of wearing it and increase the freedom of movement of the user.

Figure 9 is a schematic plan view showing part of a lifejacket according to another example embodiment of the invention; and Figure 10 is a schematic sectional view of the lifejacket, taken along the line XX of Figure 9. In the following a description will be given of the lifejacket according to another embodiment of the invention, focusing on the differences with respect to the previous modality.

With reference to figures 9 and 10, the life jacket 200 of this embodiment includes a plurality of capsules 130 containing gas, in which a gas is sealed, and a fabric structure 110, which includes a lining fabric 111 and a cover fabric 112. The fabric of liner 111 and cover fabric 112 are joined together to form a plurality of compartments S in which gas-containing capsules 130 are contained. In addition, a plurality of through holes 217 are formed, such that each through hole 217 penetrates the lining fabric 111 and the cover fabric 112 in the central area C, defined by four adjacent gas-containing capsules 130.

In other words, the lifejacket 200 of this embodiment is configured to be substantially the same as the lifejacket 100 of the preceding embodiment, except that the fabric structure 110 has multiple through holes 217, each of which penetrates the lining fabric. 111 and in the cover fabric 112, in the central area C defined by four adjacent gas-containing capsules 130. Therefore, components equal to or similar to those of the preceding modes receive the same reference numbers and their detailed descriptions will be omitted.

As before, the lifejacket 200 of this embodiment further includes, in addition to the configuration of the previous embodiment, the multiple through holes 217, each of which will penetrate the lining fabric 111 and the cover fabric 112 in the central area C defined by four capsules 130 containing gas, adjacent. Thus, it is possible not only to provide all the advantages of the previous embodiment, but also to further improve the feeling of using it and to reduce the unpleasant feeling for a user, since the water is quickly evacuated from the life jacket 200 through the through holes 217 and the life jacket 200 dries quickly in the wind, when the user leaves the water.

As in the preceding embodiment, this embodiment also applies the method of sewing the lining fabric 111 and the cover fabric 112 in the central areas C, each of which is defined by four capsules 130 containing adjacent gas, for the union between the lining fabric 111 and the cover fabric 112 so as to form the multiple compartments S in which multiple capsules 130 containing gas are contained. In consideration of the fact that the through hole 217 is formed in the central area C defined by four adjacent gas-containing capsules 130, it is preferred that a loop 215 be sewn around the through hole 217, so that the lining fabric 111 and cover fabric 112 are securely joined together.

The security garments of the present invention have been described, up to this point, by means of an example, which is a lifejacket. However, as mentioned above, the security garments of the invention may take various forms, such as bags, pants and garments. Additionally, the use of security garments is not limited to the flotation device that keeps a user afloat in the water; It can be applied to a shock absorbing device, which protects the user's body against external impacts when exercising or walking on land.

When the use of the safety garments of the invention is applied to the shock absorbing device, the gas containing capsules act as a shock absorbing material, rather than as a flotation material. Since the gas-containing capsules are configured so that the gas is sealed therein, they can exhibit an impact absorbing operation external which is better than that of an existing shock absorber material, of the related technique, in which gas is not contained, thereby protecting the user's body more perfectly.

The present invention is not limited to the preceding embodiments; but it will be apparent to the persons with experience in the matter several modifications and alterations, without leaving the spirit or the scope of the invention. Therefore, it should be understood that all such modifications and alterations are within the scope of the claims of the invention.
