Description

Technical Field

[0001] The present invention relates to functional clothing, and more specifically, to functional clothing which can easily introduce air into a plurality of air accommodation parts of the clothing through an air injection device.Background Art

[0002] Functional clothing which can create cushioning by introducing and discharging air into an area of clothing to be used for various purposes, such as such as knee protectors, body shaping pads, belly bands, life vests, rubber tubes, and wrist protectors, is being developed.

[0003] Conventional functional clothing was manufactured in a method of embedding an air tube, which can be expanded by the injection of air, in clothing. However, the conventional method has several disadvantages in that a single tube cannot inject air into the entire or a wide area of the clothing, and in that if a plurality of air tubes are embedded in the clothing, a user has to perform a complicated process to make air flow into each air tube.

[0004] Moreover, the method of embedding the air tube in the clothing is cumbersome in the manufacturing process, and since the clothing and the air tube are made of different materials, the conventional method has further disadvantages in that a user may feel foreign body sensation and the method cannot provide excellent wearability.

[0005] Meanwhile, an air injection device is combined with an area of clothing to introduce air and create cushioning into the functional clothing.

[0006] However, the conventional air injection device has a limitation in the amount of air that a user can blow in, so the user needs considerable effort and more time to fully inflate an air tube. In addition, since the conventional air injection device requires a pump for injecting air, it is inconvenient for users to carry, and the users feel inconvenient in wearing due to heavy weight when the users wear the clothing in which the conventional air injection device is embedded.Invention Technical Problem

[0007] Accordingly, the present invention has been made in view of the above-mentioned problems occurring in the related art, and it is an object of the present invention to provide functional clothing which can easily introduce air into a plurality of air accommodation parts of the clothing through an air injection device.

[0008] The aspects of the present invention are not limited to those mentioned above, and other aspects not mentioned herein will be clearly understood by those skilled in the art from the following description.Technical Solution

[0009] To accomplish the above-mentioned objects, according to the present invention, there is provided functional clothing including: a garment which includes a plurality of air accommodation parts formed between a first fabric and a second fabric arranged to face each other to accommodate air inside; and an air injection device which is connected to at least one of the plurality of air accommodation parts to inject air into the air accommodation parts, wherein around the periphery of the air accommodation parts, formed are at least one first area which divides one air accommodation part from another adjacent air accommodation part and at least one second area which communicates one air accommodation part with another adjacent air accommodation part, and when air is injected into the garment through the air injection device, the air is transferred to the plurality of air accommodation parts through the second area.

[0010] Moreover, the first area includes a film to divide the air accommodation part from another adjacent air accommodation part, and the film is bonded to the first and second fabrics.

[0011] Furthermore, the film has different widths in different areas of the functional clothing so that the functional clothing has air accommodation parts with different volumes in different areas.

[0012] Additionally, the film includes air permeable means between the air accommodation part and another adjacent air accommodation part to allow air to flow.

[0013] In addition, a polymer film coating layer is formed on one surface of at least one of the first and second fabrics, and the first area is formed by bonding at least a portion of the polymer film coating layer by one of thermal fusion, high-frequency fusion, and ultrasonic fusion.

[0014] Moreover, portions of the first and second fabrics which form the air accommodation parts are air-impermeable by the polymer film coating layer.

[0015] Furthermore, the garment includes a pocket part in which the air injection device is detachably mounted.

[0016] Additionally, the functional clothing further includes a discharge part including an outlet, which is connected to at least one of the air accommodation parts and discharges air accommodated in the garment to the outside, and a stopper, which opens and closes the outlet, wherein when the stopper is opened, the air accommodated in the plurality of air accommodation parts is transferred to the outlet through the second area.

[0017] Moreover, the air injection device includes: a connection part which is coupled to an area of the garment and communicates with at least one of the air accommodation parts to inject air into the garment; a main body part of which one end is coupled to the connection part and accommodates air at least temporarily; and an air inlet part which is formed by opening the other end of the main body part to introduce air inside the main body part. The the main body part is made of a flexible material, and when a user presses the main body part, the volume of the main body part decreases and the air accommodated in the main body part is transferred to the air accommodation parts through the connection part.

[0018] Additionally, the volume of the main body part decreases as the user grips the other end of the main body part and rolls at least a portion of the main body part towards the connection part.

[0019] In addition, a convergence part of which the the internal area decreases from the air inlet part towards the connection part is formed in one area of the main body part to guide the air accommodated in the main body part to move towards the connection part.

[0020] Moreover, the main body part is formed to accommodate air inside by bonding at least a portion of the periphery of a third fabric and at least a portion of the periphery of a fourth fabric arranged to face each other.

[0021] Furthermore, an air-impermeable polymer film coating layer is formed on one surface of at least one of the third and fourth fabrics.

[0022] Additionally, the main body part includes at least one gripping part protruding upwards from at least one area of the other end thereof, and the user opens the air inlet part by gripping the gripping part and separating the third and fourth fabrics.

[0024] According to the present invention, the functional clothing includes the plurality of air accommodation parts which communicate with each other such that air can be transferred to all of the air accommodation parts even if air is injected to one air accommodation part through the air injection device, thereby promoting user convenience.

[0025] Furthermore, according to the present invention, since the polymer film coating layer is formed on the inner surface of the fabric of the garment, the plurality of air accommodation parts which communicate air can be easily formed by using at least one of thermal fusion, high-frequency fusion, and ultrasonic fusion.

[0026] Additionally, according to the present invention, the polymer film coating layer is integrally laminated to the functional clothing, thereby providing water repellent, waterproof, and windproof functions.

[0027] In addition, according to the present invention, there is no need to embed a separate air tube in the garment, thereby simplifying the manufacturing process and eliminating the foreign body sensation caused by inclusion of air tubes made of a material different from that of the clothing.

[0028] Moreover, according to the present invention, the air injection device is formed with fabric, and the user can inject air by a simple method that the user blows air into the inner side of the fabric and rolls the fabric, thereby enhancing user convenience.

[0029] Furthermore, according to the present invention, even if the user blows air into the air injection device with less effort and fewer breaths, the clothing can be more rapidly and fully inflated.

[0030] In addition, according to the present invention, the air injection device can be conveniently carried inside the pocket without being separated from the garment due to its small volume.Description of Drawings

[0036] FIGS. 1 to 3 illustrate functional clothing according to an embodiment of the present invention, and FIG. 4 illustrates an air injection device according to an embodiment of the present invention.

[0037] Referring to FIGS. 1 to 4, functional clothing 1000 may include a garment 100, an air injection device 200, and a discharge part 300.

[0038] The garment 100 can be formed with a plurality of fabric materials in the shape of tops or bottoms that a user can wear. However, the garment 100 is not limited thereto, and can include all types of clothes or accessories formed with fabrics.

[0039] The garment 100 may include a plurality of air accommodation parts 210 that accommodate air inside. For example, the garment 100 may include at least a first fabric and a second fabric arranged to face each other in at least one area, and the air accommodation parts 110 can be formed between the first and second fabrics. The air accommodation parts 110 can allow the introduction of air through the air injection device 200, thereby forming a cushioning sensation in an area of the garment 100 and performing a heat retention function.

[0040] In an embodiment, the air accommodation part 110 can be formed in all areas of the garment 100, but is not limited thereto, and can be formed in joint areas or in certain areas requiring for shock absorption, posture support, or heat retention.

[0041] In an embodiment, at least one area of the periphery of the first fabric and at least one area of the periphery of the second fabric may have an air-impermeable polymer film coating layer. Through this, the first and second fabrics can prevent the inside air of the main body part 110 from leaking outside, and perform a shielding function which protects the user from external moisture, water, or wind. Specific details related to the polymer film coating layer 400 will be described later to avoid repeated description.

[0042] At least one first area 111 where the first fabric and the second fabric are bonded together, and at least one second area 112 where the first fabric and the second fabric are not bonded, may be formed around the air accommodation parts 110.

[0043] The first area 111 can divided one air accommodation part 110 from another. As illustrated in FIG. 7a, polymer film coating layers 400 are respectively formed on opposing surfaces of the first fabric and the second fabric, and the first area 111 can be formed by fusing at least one area of the first and second fabrics together by using at least one of thermal fusion, high-frequency fusion, and ultrasonic fusion. That is, when the first and second fabrics are heated and pressurized, the polymer film coating layers 400 are melt, such that the first and second fabrics are bonded together, thereby forming the first area 111. However, the present invention is not limited thereto, and various modifications can be made, such as forming the polymer film coating layer 400 on only one surface of either the first or second fabric. The fusion method is just an example and the present invention is not limited thereto. Additionally, for example, the plurality of first areas 111 can be formed with predetermined lengths and spaced apart at predetermined intervals, but they are not limited thereto and can have various intervals or lengths.

[0044] In another embodiment, as illustrated in FIG. 7b, the first area 111 can include a film 1111 for dividing one air accommodation part 110 from another. For example, polymer film coating layers 400 are respectively formed on opposing surfaces of the first and second fabrics, and the first area 111 can be formed by fusing the film 1111 to at least one area of the first and second fabrics by using at least one of thermal fusion, high-frequency fusion, and ultrasonic fusion. In addition, the film 1111 can be bonded to the first and second fabrics using an adhesive, or by other adhesive means. In another embodiment, the first area 111 dividing air accommodation parts using the film 1111 can be expanded to increase the air capacity of the air accommodation part 110.

[0045] As illustrated in FIGS. 8a, 8b, and 8c, the film 1111 forming the first area 111 can include air permeation means 1112 and 1113 to allow air to flow between the air accommodation parts 110. FIGS. 8a, 8b, and 8c illustrate the film portion (dotted circle area in FIG. 7b) in detail. Additionally, the film 1111 may be made of a porous material that allows air to pass through. The air permeable means 1112 and 1113 illustrated in FIGS. 8a, 8b and 8c allow air to flow between the air accommodation parts 110, thereby ensuring uniform air accommodation in the air accommodation parts 110, maintaining the shape of the clothing better, and allowing the user to move more freely. The air permeable means 1112 and 1113 can be configured, for example, to have an area without a film as in reference number 2112, or to have holes 1113 formed in the film 1111, which allow air to pass through.

[0046] The width of the film 1111 forming the thickness of the first area 111 may vary depending on the area of the clothing. For example, the volume of the air accommodation parts 110, which includes the first fabric, the second fabric, and the film 1111, can vary depending on the width of the film 1111. For instance, if the width of the film 1111 is relatively wide, the volume of the air accommodation parts 110, which includes the first fabric, the second fabric, and the film 1111, can be relatively large and can have higher thermal insulation and cushioning. For example, if the width of the film 1111 is relatively narrow, the volume of the air accommodation parts 110, which includes the first fabric, the second fabric, and the film 1111, can be relatively small, and can enhance the user's ease of movement. For example, in areas of the clothing 1000 which require higher insulation and where the user's movement is small, the first area 111 can include the film 1111 which is relatively thick. Furthermore, in areas related to the user's ease of movement, such as areas corresponding to the user's joints, the first area 111 can include the film 1111 which is relatively thin. The overall thickness of the film 1111 can be determined based on the insulation of the clothing 1000.

[0047] The second area 112 can enable air communication between one air accommodation part 110 and another adjacent air accommodation part 110. For example, the second area 112 can be formed between at least a portion of the plurality of first areas 111. When air is injected into the garment 100 through the air injection device 200, air can be sequentially or simultaneously transmitted to the plurality of air accommodation parts 110 through the second area 112. For instance, the air injected into the first air accommodation part from the air injection device 200 can be transferred to at least one second air accommodation part formed adjacent to the first air accommodation part through the second area 112, and subsequently to at least one third air accommodation part adjacent to that, in a sequential or simultaneous manner.

[0048] The garment 100 may include a pocket part 120 in which the air injection device 200 can be detachably mounted inside. For example, when at least a portion of the periphery of fabric overlaid is joined to one surface of the garment 100, the pocket part 120 having an accommodating space can be formed inside. The top of the pocket part 120 may have an opened area to expose the air injection device 200, which is accommodated inside, above the top of the open area. Furthermore, when the user does not use the air injection device 200, the air injection device 200 can be folded and stored or carried inside the pocket part 120.

[0049] In an embodiment, as illustrated in FIGS. 1 and 2, the pocket part 120 can be provided on the outer surface of the garment 100, but is not limited thereto and can also be provided on the inner surface of the garment 100, or on both the outer and inner surfaces. In addition, the pocket part 120 can be provided at the lower portion of the torso area of the garment 100, but is not limited thereto and can be provided in various areas such as the trunk, the shoulders, or the arm areas of the garment 100.

[0050] The air injection device 200 can be connected to at least one of the plurality of air accommodation parts 110, thereby enabling the injection of air into the air accommodation parts 110 of the garment 100.

[0051] In an embodiment, the air injection device 200 may include a connection part 210, a main body part 220, and an air inlet part 230.

[0052] The connection part 210 can be coupled to a predetermined area of the garment 100 (especially the air accommodation part 110) and communicate with at least one of the plurality of air accommodation parts 110 to inject air into the garment 100. For example, the connection part 210 can be integrally formed by bonding with a portion of the garment 100, but is not limited thereto and can be formed to be detachable from the garment 100.

[0053] The main body part 220 is made of a plurality of fabrics, and can temporarily accommodate air before air is injected into the garment 100 through the connection part 210. For this purpose, one end of the main body part 220 can be connected to the connection part 210, and can be formed to have sufficient volume and length to accommodate air.

[0054] In an embodiment, the main body part 220 can be made of a third fabric and a fourth fabric which are arranged to face each other, and at least a portion of the periphery of the third fabric and at least a portion of the periphery of the fourth fabric can be bonded to accommodate air therein. Any one among various bonding methods such as thermal fusion, high-frequency fusion, and ultrasonic fusion can be used, but the method is not limited thereto, and all known bonding methods can be utilized.

[0055] In an embodiment, an air-impermeable polymer film coating layer 400 can be formed on at least one surface of one of the third and fourth fabrics to prevent the inside air of the main body part 220 from leaking outside. Specific details related to the polymer film coating layer 400 will be described later to avoid repeated description.

[0056] The main body part 220 is made of a flexible material, and can decrease in volume when the user presses the main body part 220. For example, the user can press the main body part 220 by gripping one end and rolling at least a portion of the main body part 220 towards the connection part 210. As the volume of the main body part 220 decreases, the air accommodated in the main body part 220 can be transferred to the air accommodation part 110 through the connection part 210. As described above, the air transferred to the air accommodation part 110 can be distributed to the plurality of air accommodation parts 110 through the second area 112.

[0057] For example, the air injection device 200 mounted on the garment 100 (namely, the main body part 220) can be rolled to reduce the volume and stored in the garment 100 (particularly in the pocket part 120). Therefore, the user can conveniently carry the air injection device 200 in small volume and size without separating the air injection device 200 from the garment 100, use the air injection device regardless of location and time, thereby facilitating portability.

[0058] A convergence part 221 may be formed in one area of the main body part 220 to guide the air accommodated in the main body part 220 towards the connection part 210. For this purpose, the convergence part 221 can be shaped such that the internal area or width of the convergence part 221 decreases from the air inlet part 230 towards the connection part 210. Accordingly, the air accommodated in the main body part 220 can become more concentrated as it moves from the air inlet part 230 towards the connection part 210, allowing for more efficient air injection into the garment 100 through the connection part 210.

[0059] At one end of the main body part 220 (particularly, one end where the air inlet part 230 is formed), at least one gripping part 222 protruding upwards from at least one area may be formed. The user can open the air inlet part 230 by gripping the gripping part 222 and separating the third and fourth fabrics. For example, the gripping part 222 can be formed on both the third and fourth fabrics, but is not limited thereto, or can be formed on only one of these fabrics. Additionally, for instance, the gripping part 222 can be formed only in one area of one end of the main body part 220 or across the entire area of that end, but is not limited thereto, and can include any shape that protrudes upwards enough to be gripped by the user.

[0060] In an embodiment, the gripping part 222 may include a first gripping part 222' provided on the third fabric and a second gripping part 222" provided on the fourth fabric. The first gripping part 222' and the second gripping part 222" can be respectively formed on opposite ends in the width direction of the main body part 220 so that they correspond to each other. Accordingly, the user can more easily separate the third and fourth fabrics by gripping the first gripping part 222' and the second gripping part 222" respectively.

[0061] In an embodiment, the first gripping part 222' may be formed in one area of one end of the third fabric of the main body part 220, and a first opening part may be formed in another area of that end. Moreover, to correspond the first gripping part and the first opening part, a second gripping part 222" may be formed in one area of one end of the fourth fabric of the main body part 220, and a second opening part may be formed in another area of that end. For example, the first and second opening parts can be formed such that each end of the third and fourth fabrics protrudes less upwards than the first gripping part 222' and the second gripping part 222", respectively. Accordingly, the first gripping part 222' is exposed from the fourth fabric side by the second opening part, and the second gripping part 222" is exposed from the third fabric side by the first opening part, so that the user can more easily grip the first and second gripping parts 222' and 222" to open the air inlet part 230.

[0062] In an embodiment, an expansion part may be formed in one area of the main body part 220 to guide the external air into the inside of the main body part 220 when the air inlet part 230 is opened. For this purpose, the expansion part can be shaped such that the internal area or width of the expansion part expands from the connection part 210 towards the air inlet part 230. Before opening the air inlet part 230, there may be no air accommodated inside the main body part 220, and pressure is low. In the above state, when the air inlet part 230 is opened, external air can flow instantaneously into the low-pressure interior of the main body part 220. At this time, the expansion part can guide a greater amount of external air into the increasing open area of the main body part 220.

[0063] In addition, even when the user blows air into the main body part 220 through the air inlet part 230, the air blown by the user, along with external air, is guided into the interior of the main body part 220, thereby rapidly increasing the volume of the main body part 220 even with less effort and fewer breaths from the user.

[0064] The air inlet part 230 is formed by opening another end of the main body part 220 (the end opposite the connection part 210), thereby allowing air to be introduced into the interior of the main body part 220. For example, the air inlet part 230 can be formed by fully opening the other end of the main body part 220, but is not limited thereto, and can also be formed by opening only a portion of the other end of the main body part 220.

[0065] The discharge part 300 can be connected to at least one of the plurality of air accommodation parts 110 to discharge the air accommodated in the air accommodation part 110 of the garment 100 to the outside.

[0066] In an embodiment, the discharge part 300 can include an outlet and a stopper. The outlet can be connected to an area of the garment 100 (particularly, the air accommodation part 110) to discharge the air accommodated in the garment 100 to the outside from the garment 100.

[0067] The stopper can open and close the outlet. For example, when the stopper stops the outlet, it can minimize the air leakage to the outside while air is being injected into the garment 100 through the air injection device 200, thereby allowing for more efficient air injection. Additionally, even after the air is injected, the stopper can prevent and seal the air accommodated in the garment 100 from leaking to the outside.

[0068] Meanwhile, when the user opens the stopper to open the outlet, the air accommodated in the garment 100 can be discharged to the outside. In other words, when the user opens the outlet and presses at least one area of the garment 100, the air accommodated in the plurality of air accommodation parts 110 can be sequentially or simultaneously transferred through the second area 112 and discharged to the outside through the outlet.

[0069] FIG. 5 is a cross-sectional view of the polymer film coating layer 400 formed on the fabric of the garment and the air injection device according to an embodiment of the present invention.

[0070] Here, the fabric can be at least one of the first to fourth fabrics described with reference to FIGS. 1 to 4.

[0071] Referring to FIG. 5, the polymer film coating layer 400 is formed by laminating a thermoplastic polymer film 420 on one surface of a base fabric 410, and can include the base fabric 410, the thermoplastic polymer film 420, and an adhesive 430 formed therebetween.

[0072] In an embodiment, the polymer film coating layers 400 can be respectively formed on both the first and second fabrics (or the third and fourth fabrics) to face each other. In this case, by laminating the polymer film coating layers 400 to each other, a sealed space can be formed inside, or functional materials can be shielded from exposure to external moisture or dampness.

[0073] The base fabric 410 refers to the cloth that forms the raw material of the garment, for example, a woven fabric made by weaving natural and / or synthetic fibers.

[0074] The thermoplastic polymer film 420 can refer to a film composed of a polymer with thermoplastic properties that can be melted or deformed by heating. In an embodiment, when air and moisture permeable spaces are removed by the thermoplastic polymer film 420, the polymer film coating layer 400 can have waterproof and windproof functions.

[0075] The thermoplastic polymer film 420 can be composed of, for example, at least one or a combination of polyurethane (PU), thermoplastic polyurethane (TPU), polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyethylene terephthalate (PET), linear low-density polyethylene (LLDPE), polyimide (PI), polycarbonate (PC), acrylic resin, and polystyrene (PS), and preferably, at least one of polyurethane (PU), polyethylene (PE), polypropylene (PP), and polyvinyl chloride (PVC). However, the thermoplastic polymer film 420 is not limited thereto.

[0076] In the embodiment, the thermoplastic polymer film 420 may have a thickness in the range of 20 um to 200 um, and preferably, 40 um to 100 um. However, the thermoplastic polymer film 420 is not limited thereto. If the thickness of the thermoplastic polymer film 420 is less than 20 um, the windproof or waterproof function may decrease, or the processability such as lamination between polymer film coating layers may decrease. If the thickness of the thermoplastic polymer film 420 exceeds 200 um, the mobility in clothing manufacturing may decrease.

[0077] Furthermore, in the embodiment, the thermoplastic polymer film 420 can be configured to have a hardness in the range of Shore 80A to 95A, and preferably, 85A to Shore 90A. However, the thermoplastic polymer film 420 is not limited thereto.

[0078] In addition, in the embodiment, the thermoplastic polymer film 420 can have a heat deformation temperature in the range of 140°C to 200°C, and preferably, 160°C to 180°C. However, the thermoplastic polymer film 420 is not limited thereto.

[0079] The adhesive 430 can be coated on one surface of the thermoplastic polymer film 420 to laminate the base fabric 410 with the thermoplastic polymer film 420. In the embodiment, the adhesive 430 can be, for example, a thermosetting adhesive which is hardened in a predetermined temperature range (for example, at 80°C to 90°C). The adhesive 430 may be at least one of a solvent type, a hot melt type, or an urethane type adhesive, but is not limited thereto.

[0080] In the embodiment, when the adhesive 430 between the base fabric 410 and the thermoplastic polymer film 420 is heat-hardened, the base fabric 410 and the thermoplastic polymer film 420 can be laminated. In this instance, the heat-hardening process can be performed by a laminating or hot press process. Here, laminating means a method of heating and pressing a target by passing the target between a plurality of heating rollers. For example, when stacked base fabric 410 and thermoplastic polymer film 420 pass between the plurality of heated heating rollers to be heated and pressed, the adhesive 430 can be heat-hardened, such that the base fabric 410 and the thermoplastic polymer film 420 can be laminated.
