Description

[Technical field]

[0001] The present invention relates to a life jacket, an air-inflation member provided therein, and a method for connecting the life jacket and the air-inflation member. [Background technology]

[0002] Life jackets are used to protect the user from various marine accidents that are likely to occur during marine activities such as fishing boats, ships, fishing, marine reporting, marine work, and safety personnel. By wearing them around the upper body, including the back of the neck, shoulders, and chest, they help users float even if they drown in water, thereby protecting their lives.

[0003] Fig. 1 shows a conventional life jacket. Fig. 1 shows an automatic inflatable life jacket among conventional life jackets. In the conventional automatic inflatable life jacket 10, water that seeps into the gas supply device 30 in the event of a water rescue dissolves a fastener (not shown) and passes through the inlet of the cartridge 31, so that the gas in the gas cylinder 34 is quickly injected into the jacket member 20, filling the jacket member 20 with gas.

[0004] If the injected gas is insufficient or if the injected gas naturally escapes over time, the life jacket needs additional gas, and in such a case, an air inlet member 50 is provided that allows air to be manually injected. Meanwhile, the air inlet member 50 also functions as a structure for deflating the life jacket after it has been used.

[0005] The conventional air-blowing member 50 is provided as a tube member bent in an "L" shape so that the mouthpiece 54 is located near the wearer's mouth when the life jacket is worn. In addition, since the tube member is bent in an "L" shape, the air-blowing member 50 can be closely attached to the life jacket.

[0006] However, in the conventional air blowing member 50, as shown in Fig. 2, the part (B) where the second part 53 is projected on the base part 51 is not sufficiently bonded due to the folded part between the first part 52 and the second part 53 during manufacturing, and only the remaining part (A) is bonded, resulting in a problem of product defects due to the insufficient bonded part (B). Also, the mouthpiece 54 is fixed toward the wearer's mouth, so in an emergency, someone else cannot inject air on behalf of the wearer.

[0007] Another conventional technique is shown in Fig. 3. Although the straight, unfolded air blowing member 150 as shown in Fig. 3 has a low adhesion failure rate with the jacket during manufacturing, its length is short and the mouth of the mouth cannot be directed toward the wearer's mouth or cannot be located close to the wearer's mouth, which is inconvenient when inflating air. DISCLOSURE OF THEINVENTION [Problem to be solved by the invention]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0037] Hereinafter, the embodiments of the present invention will be described in more detail with reference to the accompanying drawings. The embodiments of the present invention can be modified in various ways, and the scope of the present invention should not be interpreted as being limited to the following embodiments. The embodiments are provided to more completely explain the present invention to those having average knowledge in the art. Therefore, the shapes of elements in the drawings are exaggerated to emphasize a clearer description.

[0038] 4 shows a life jacket 100 according to an embodiment of the present invention. Referring to FIG. 4, the life jacket 100 includes a jacket member 20, a gas supply device 300, and an air-blow member 500.

[0039] The jacket member 20 is a member that a wearer wears on the upper body including the back of the neck, shoulders, and chest. The jacket member 20 can be filled with gas. When the jacket member 20 is filled with gas, the jacket member 20 can float on water. In this way, the jacket member 20 can float the wearer's body on the water.

[0040] The gas supply device 300 is provided on one of the left and right sides of the jacket member 20. The gas supply device 300 may be located anywhere as long as the wearer can easily operate it by hand, but is usually provided on the underside of the jacket member 20 where the wearer can easily operate it by hand. When water is injected into the gas supply device 300 or when the safety pin 310 is pulled, the firing needle fires the gas cylinder 340. When the gas cylinder 340 is fired, the jacket member 20 is filled with gas.

[0041] The air blowing member 500 may be provided on one side of the jacket member 20 where the gas supply device 300 is provided, or on the other side. In the drawings, the air blowing member 500 and the gas supply device 300 are provided on both the left and right sides of the jacket member 20, but they may all be provided on the same side. It is sufficient that the air blowing member 500 is located in a part of the jacket member suitable for a user to inject air through a nozzle (see FIG. 6) 535. In order to prevent unnecessary waste of materials, it is preferable that the air blowing member 500 is provided on the upper side of the jacket member 20. The air blowing member 500 will be described in detail with reference to FIG. 5.

[0042] 5 shows an air blowing member 500 according to an embodiment of the present invention. The air blowing member 500 is configured to blow air into the jacket member 20. The air blowing member 500 includes a base part 510 and a tube part 560. According to an embodiment, the base part 510 and the tube part 560 may be integrally formed. The air blowing member 500 may be made of, for example, a urethane material.

[0043] The base part 510 is configured to provide a bonding surface (e.g., an upper surface of the base part 510) with the jacket member 20. The bonding surface of the base part 510 is bonded, e.g., thermally bonded, to the jacket member 20. The base part 510 is provided in a plate shape. In one embodiment, the base part 510 is provided in a ring-shaped disk. The ring shape is not limited to a circular plate, but can be various shapes, e.g., oval, rectangular. The larger the area of ​​the base part 510, the larger the bonding surface with the jacket member 20.

[0044] In one embodiment, the tube part 560 extends from the base part 510. The tube part 560 includes a first tube portion 520, a second tube portion 530, and a flexible portion 540. The first tube portion 520 extends from the base part 510. A flexible portion 540 is provided between the first tube portion 520 and the second tube portion 530, and continues the first tube portion 520 and the second tube portion 530. The flexible portion 540 divides the tube part 560 into the first tube portion 520 and the second tube portion 530. In one embodiment, the first tube portion 520 is included, but the first tube portion 520 and / or the second tube portion 530 may be omitted if necessary. In one embodiment, the first tube portion 520 may be omitted and the flexible portion 540 may be extended from the base part 510 (not shown). According to one embodiment, the first tube portion 520 and the second tube portion 530 may be omitted, and the flexible portion 540 may form the entire tube part 560 (not shown). When the flexible portion 540 forms the entire tube part 560, it may be embodied in the above-mentioned wrinkled tube shape, or it may be embodied in the shape of a tube made of a flexible material without using a wrinkled tube, in which case it is easy to combine with other components (e.g., a cap, a base part).

[0045] In one embodiment, the flexible portion 540 is provided to be adjustable in length. In one embodiment, the flexible portion 540 is provided to be adjustable in angle at a set angle. In the illustrated embodiment, the flexible portion 540 is provided in a wrinkled tube shape. The wrinkled tube allows for length and angle (direction) adjustment. In the illustrated embodiment, the flexible portion 540 is provided in a wrinkled tube shape, but is not limited thereto, and it is obvious to those skilled in the art that the flexible portion 540 can be modified with a flexible material that allows for free length and / or angle adjustment. According to one embodiment of the present invention, the length and angle (direction) of the tube member can be adjusted, so that the direction and position of the nozzle can be freely adjusted, allowing the wearer to inject air in a comfortable state, and in an emergency situation, another person can inject air on behalf of the wearer. In addition, even if the wearers' bodies are different from each other, the wearer can inject air comfortably by appropriately adjusting the length and direction of the tube member while wearing the life jacket.

[0046] A cap 550 is coupled to an end of the tube member 560. In one embodiment, the cap 550 is coupled to the second tube portion 530. The cap 550 opens when injecting or defusing air, and closes when the injection of air is completed, thereby blocking the flow of air. Although not shown, the tube member 560 may be provided with a check valve (not shown) at an end of the tube member 560, for example, near the mouthpiece (see FIG. 6) 535. The check valve (not shown) allows air to flow in one direction. The check valve (not shown) opens in the direction of the air injection when injecting air, and closes when the injection of air is stopped, thereby preventing air from escaping to the outside.

[0047] 6 and 7 show a method of joining a jacket member and an air blowing member when a base part and a tube part are integrally molded according to an embodiment of the present invention.

[0048] The raw material 20a forming the jacket member 20 is prepared. The raw material 20a is, for example, made of a waterproof material. The raw material 20a may include, for example, a lining made of a waterproof material and an outer material for protecting the lining. The lining may be made of a vinyl material. The outer material may be made of a fabric material that is relatively comfortable when in contact with the body compared to vinyl. The outer material of the raw material 20a may be omitted. A hole is formed in the raw material 20a. The hole in the raw material 20a is formed to a size that allows the tube part 560 of the air-blowing member 500 to pass through but does not allow the base part 510 to pass through. The tube part 560 passes through the hole while the upper surface (joining surface) of the base part 510 of the air-blowing member 500 overlaps the raw material 20a. Then, the raw material 20a and the base part 510 come into contact with each other. Thus, the raw material 20a is placed on the top (joining surface) of the base part 520, and the tube part 560 passes through the hole of the raw material 20a. Then, with the base part 520 placed underneath, the ring member 610, which assists in pressurization and heat transfer, is joined to the top of the raw material 20a (the tube part 560 is passed through the inner diameter of the ring member 610). The raw material 20a and the base part 510 can be bonded by thermal bonding. Examples of thermal bonding include heat bonding, high frequency bonding, and ultrasonic bonding. The press members 620 and 630 are placed on the top of the ring member 610, and the raw material 20a of the jacket member 20 and the base part 510 are thermally bonded by the energy transferred by pressurizing and heating the ring member 610. At this time, the ring member 610 presses the entire periphery of the base part 510, so that the entire periphery of the base part 510 adheres to the raw material 20a, preventing poor adhesion. According to an embodiment, the pressing members 620 and 630 directly contact the raw material 20a and the base part 510 without using the ring member 610 to transfer energy.

[0049] The press members 620 and 630 may have a circular cross section. The press members 620 and 630 may be provided as a first press member 620 and a second press member 630. The first press member 620 and the second press member 630 may be combined with each other to form a circle. The cross section of the first press member 620 and the second press member 630 that contacts the ring member 610 may be provided to be equal to the cross section of the ring member 610 when the first press member 620 and the second press member 630 are combined. Meanwhile, the first press member 620 and the second press member 630 may be formed as a single unit.

[0050] As described above, when the jacket member and the air blowing member are joined together, the periphery of the base part 520 can be uniformly bonded to the fibers 20a, thereby reducing adhesion failure between the jacket member and the air blowing member.

[0051] According to another embodiment, the base part and the tube part may be formed in two pieces. Figure 8 is an exploded perspective view of an air blowing member 1500 according to another embodiment, the base part and the tube part are formed in two pieces.

[0052] The air blowing member 1500 according to another embodiment includes a tube part 1560 including a first tube part 1520, a second tube part 1540, and a flexible part 1540, a base part 1510, and a cap 1550. The tube part 1560 and the base part 1510 are provided as separate parts. The tube part 1560 and the base part 1510 can be bonded together by a bond as described below.

[0053] When the tube part 1560 and the base part 1510 are provided as separate parts, the tube part 1560 may be made entirely flexible. The base part 1510 may be made of a material that can be easily thermally bonded to the base fabric 20a.

[0054] The base part 1510 includes a base portion 1511 and an extension portion 1512. The base portion 1511 is a portion that is connected to a life jacket. The extension portion 1512 is a portion that extends from the base portion 1511 and is connected to the tube part 1560. The base portion 1511 is provided as a ring-shaped plate as described above. The extension portion 1512 extends from the inner diameter of the base portion 1511.

[0055] 9, 10, 11 and 12 show a method of joining a jacket member and an air blowing member when a base part and a tube part are molded as two pieces according to another embodiment of the present invention. The description will be given with reference to Figs. 9, 10, 11 and 12.

[0056] FIG. 9 is a perspective view for explaining the connection between the air-blowing member and the jacket member.

[0057] 9 and 10, the original 20a forming the jacket member 20 is prepared. A hole 20b is formed in the original 20a. An extension 1512 extended from a base part 1511 of the base part 1510 passes through the hole 20b, and the upper surface (joining surface) of the base part 1511 contacts the lower surface of the original 20a. Then, a ring member 610 for assisting pressure and heat transfer is joined to the upper surface of the original 20a through the extension 1512 of the base part 1510. At this time, the ring member 1610 presses the entire periphery of the base part 1511 of the base part 1511, so that the entire periphery of the base part 1510 is bonded to the original 20a, preventing poor bonding. The extension 1512 of the ring member 1610 can be formed to be high. Therefore, the press member 1620 can be provided with a flat bottom surface without a hole.

[0058] 11, the raw fabric 20a and the base part 1510 may be bonded by thermal bonding. Examples of thermal bonding include heat bonding, high frequency bonding, ultrasonic bonding, etc. The raw fabric 20a and the base part 1510 of the jacket member 20 are thermally bonded by the energy transferred by placing the press member 1620 on the ring member 1610 and pressurizing and heating the ring member 1610.

[0059] 12, after the base part 1510 is connected to the base 20a, the tube part 1560 is connected to the extension part 1512 of the base part 1510. The tube part 1560 and the extension part 1512 may be bonded by a bond 1560.

[0060] In the above embodiment, the tube part 1560 is attached to the base part 1510 after the base part 1510 is attached to the raw material 20a, but it is also possible to change the procedure and attach the base part 1510 to the tube part 1560 first, and then attach the base part 1510 to the raw material 20a. In this case, they can be attached by the attachment method described above with reference to Figs. 6 and 7.

[0061] The above detailed description is illustrative of the present invention. The above content shows and describes the preferred embodiment of the present invention, and the present invention can be used in various different combinations, modifications, and environments. That is, changes or modifications are possible within the scope of the concept of the invention disclosed in the present specification, the scope of equivalents to the disclosed content, and / or the scope of the technology or knowledge of the art. The described embodiments are intended to explain the best conditions for realizing the technical ideas of the present invention, and various modifications are possible as required by the specific application field and use of the present invention. Therefore, the above detailed description of the invention is not intended to limit the present invention to the disclosed embodiment. The appended claims should be construed to include other embodiments. [Industrial Applicability]
