Description

本発明は、高温および/または高湿の環境や、オフィスや家庭など快適性が必要とされる様々な着用シーンにおいて、好適に用いることができる衣服に関するものである。 TECHNICAL FIELD The present invention relates to clothing that can be suitably used in high temperature and/or high humidity environments, offices, homes, and various other wearing situations where comfort is required.

地球温暖化対策として、夏場にエアコンの設定温度を高くすることや冬場にエアコンの設定温度を低くすることは、二酸化炭素排出量の削減に有効な手段の一つである。しかしながら、エアコンの温度を変更した場合、オフィスや住居などの室内空間における快適性が低下し、特に夏場においては発汗によるべたつきによって不快に感じることが問題となる。そこで、ファンを用いることにより衣服内に外気を送り込み、快適性を維持するための衣服が提案されている。 As a measure against global warming, increasing the set temperature of air conditioners in the summer and lowering the set temperature of the air conditioners in the winter is one effective means for reducing carbon dioxide emissions. However, when the temperature of the air conditioner is changed, the comfort in indoor spaces such as offices and residences decreases, and there is a problem that the user feels uncomfortable due to stickiness caused by sweating, especially in the summer. Therefore, clothing has been proposed that uses a fan to blow outside air into the clothing to maintain comfort.

例えば、特許文献1では、外部の空気を取り込むファンを備えてなる、表地と裏地とを有している空調服であって、表地と裏地との間の空間に空気の流れを強制的に生じさせることが可能な空調服が提案されている。この提案によると、表地と裏地との間の空間に空気の流れを強制的に生じさせることにより、効果的に身体を冷却することができるとしている。 For example, Patent Document 1 discloses an air-conditioned garment that includes a outer material and a lining material and is equipped with a fan that takes in outside air, in which a flow of air is forcibly created in the space between the outer material and the lining material. Air-conditioned clothing has been proposed. According to this proposal, the body can be effectively cooled by forcing air flow into the space between the outer fabric and the lining.

また、特許文献2では、着用者を覆う衣服本体と、前記衣服本体の内側の空間に連通する筒状の通気部と、を有し、さらに前記通気部が、送風装置の送風部に着脱可能な通気口を有する衣服が提案されている。この提案によると、衣服内部の空間と連通する筒状の通気部に、送風装置の送風部が装着可能であり、送風装置により外部からの空気を衣服内に取り込んで身体を冷却することができるとしている。 Further, Patent Document 2 has a clothing main body that covers the wearer, and a cylindrical ventilation section that communicates with a space inside the clothing main body, and further, the ventilation section is detachable from the ventilation section of an air blowing device. Clothing with ventilation holes has been proposed. According to this proposal, the blower section of a blower can be attached to a cylindrical ventilation section that communicates with the space inside the clothes, and the blower can draw air from outside into the clothes to cool the body. It is said that

特許文献1で開示されている技術によると、空調服の表地と裏地との間の空間に空気の流れを強制的に生じさせることにより、効率的に身体を冷却することができる。しかしながら、該技術は、衣服内(表地と裏地の間)に空気をため込む構造となることから送風流量の大きなファンを搭載する必要があり、かつ衣服が大きく膨らんだ状態となるため、意匠性の観点からオフィスや家庭などの着用シーンには適さないものであった。 According to the technology disclosed in Patent Document 1, the body can be efficiently cooled by forcibly generating air flow in the space between the outer material and the lining of the air-conditioned clothing. However, since this technology creates a structure in which air is trapped inside the garment (between the outer material and the lining), it is necessary to install a fan with a large air flow rate, and the clothing is left in a bulging state, resulting in poor design. From this point of view, it was not suitable for wearing at the office or at home.

また、特許文献2に開示されている技術によると、衣服内部の空間と連通する筒状の通気部に装着した送風装置により、外部からの空気を衣服内に取り込むことで身体を冷却することができる。しかしながら、該技術は、ベルトなどを用いて腰部に送風装置を取り付けなければならず、その違和感から着用快適性に劣る物であった。加えて、該技術は、衣服内に流入した空気が衣服本体の生地を通して空気が流出しないように、タフタ生地など空気を通しにくい生地を用いており、空気の流出が袖口や襟元に限定される。そのため、送風装置稼働時には衣服が大きく膨らんだ状態となり、意匠性の観点からオフィスや家庭などの着用シーンには適さないものであった。 According to the technology disclosed in Patent Document 2, the body can be cooled by taking in air from the outside into the garment using a blower attached to a tubular ventilation section that communicates with the space inside the garment. However, this technology requires the blower to be attached to the waist using a belt or the like, which makes the garment less comfortable to wear due to the discomfort it causes. In addition, this technology uses a fabric that is difficult for air to pass through, such as taffeta, so that the air that flows into the garment does not flow out through the fabric of the garment itself, and the outflow of air is limited to the cuffs and collar. Therefore, when the blower is operating, the garment becomes greatly inflated, and from the standpoint of design, this is not suitable for wearing in an office or at home.

本発明の課題は、上記従来技術の問題点を解決し、衣服内の蒸れ感や暑熱感を抑制して衣服内環境を快適に保つことができ、かつオフィスや家庭などの着用シーンにおいても意匠性や着用快適性に優れた衣服を提供することにある。 An object of the present invention is to solve the above-mentioned problems of the conventional technology, to suppress the feeling of stuffiness and heat inside the clothes, to maintain a comfortable environment inside the clothes, and to maintain a comfortable design even when worn in offices, homes, etc. Our goal is to provide clothing with excellent wearability and comfort.

本発明者らが検討を進めたところ、皮膚水分量が多く動きが複雑でない背中部や、発汗量の多い腋下部に対し、身体に略平行な風を局所的に送風することにより、効率的に身体を冷却することが可能であるという知見を得た。また、着用快適性は衣服内温度だけでなく衣服内湿度も大きく関与しており、衣服内の蒸れ感を抑制することにより着用快適性が大きく向上することが判明した。 The inventors conducted research and found that by locally blowing air approximately parallel to the body to the back area where the skin has a high water content and movements are not complicated, and the underarm area where there is a large amount of sweat, it is possible to efficiently We have obtained the knowledge that it is possible to cool the body. Furthermore, it has been found that wearing comfort is largely influenced by not only the temperature inside the clothes but also the humidity inside the clothes, and that the wearing comfort can be greatly improved by suppressing the feeling of stuffiness inside the clothes.

そこで、本発明者らは鋭意検討を重ねた結果、通気度の高い生地を衣服に用いることで衣服の膨らみや衣服内の蒸れ感を抑制することができ、さらに通気度の高い生地であっても効率的に身体を冷却することができるよう、衣服内の風に指向性を付与するための流路形成部を衣服内側に設けることによって、意匠性や着用快適性に優れ、オフィスや家庭などの着用シーンに好適な衣服となることを見出し、本発明を完成させるに至った。 Therefore, as a result of extensive research, the inventors of the present invention found that by using fabrics with high breathability for clothing, it is possible to suppress the swelling of clothes and the feeling of stuffiness inside clothes. By providing a flow path forming part inside the clothes to give directionality to the wind inside the clothes, so that the body can be efficiently cooled, it has an excellent design and is comfortable to wear, making it ideal for offices and homes. The present inventors have discovered that this is a garment suitable for wearing situations, and have completed the present invention.

すなわち、本発明は、前記の課題を解決せんとするものであり、通気度が50~500cm/cm/sの生地からなる衣服であって、送風ファンユニットを具備しており、かつ、衣服内の風に指向性を付与するための流路形成部を衣服内側に具備してなることを特徴とする衣服である。 That is, the present invention aims to solve the above-mentioned problems, and is a garment made of a fabric with an air permeability of 50 to 500 cm 3 /cm 2 /s, which is equipped with a blower fan unit, and This garment is characterized by having a flow path forming part inside the garment for imparting directionality to the wind inside the garment.

本発明の衣服は、通気度が50~500cm/cm/sの生地からなる衣服であって、送風ファンユニットを具備しており、かつ、衣服内の風に指向性を付与するための流路形成部を衣服内側に具備してなることを特徴とする衣服である。以下に本発明の詳細について説明する。 The garment of the present invention is made of fabric having an air permeability of 50 to 500 cm3 / cm2 /s, and is characterized in that it is equipped with a blower fan unit and has a flow path forming part on the inside of the garment for imparting directionality to the air inside the garment. The details of the present invention are described below.

本発明の衣服は、生地の通気度が50~500cm/cm/sであることが重要である。本発明における生地の通気度とは、実施例記載の方法で測定される値を指す。生地の通気度を50cm/cm/s以上、好ましくは70cm/cm/s以上、より好ましくは90cm/cm/s以上、さらに好ましくは100cm/cm/s以上とすることにより、汗の蒸散性に優れるため発汗時の蒸れ感を抑制できるとともに、衣服の膨らみを抑制することが可能となる。また、生地の通気度を500cm/cm/s以下、好ましくは450cm/cm/s以下、より好ましくは400cm/cm/s以下、さらに好ましくは350cm/cm/s以下とすることにより、生地の機械的特性が良好となり、衣服製造時の工程通過性や取り扱い性が良好であり、使用時の耐久性にも優れる衣服となる。また、生地が薄地となり過ぎず、裏地を設けなくても違和感なく着用することができる。 It is important for the clothing of the present invention that the fabric has an air permeability of 50 to 500 cm 3 /cm 2 /s. The air permeability of the fabric in the present invention refers to a value measured by the method described in Examples. The air permeability of the fabric is 50 cm 3 /cm 2 /s or more, preferably 70 cm 3 /cm 2 /s or more, more preferably 90 cm 3 /cm 2 /s or more, even more preferably 100 cm 3 /cm 2 /s or more. As a result, it is possible to suppress the feeling of stuffiness during sweating due to excellent sweat evaporation properties, and it is also possible to suppress the swelling of clothes. Also, the air permeability of the fabric should be 500 cm 3 /cm 2 /s or less, preferably 450 cm 3 /cm 2 /s or less, more preferably 400 cm 3 /cm 2 /s or less, even more preferably 350 cm 3 /cm 2 /s or less. By doing so, the mechanical properties of the fabric become good, the processability and handleability during garment manufacturing are good, and the garment becomes excellent in durability during use. In addition, the fabric is not too thin and can be worn comfortably without a lining.

本発明の衣服は、吸湿性繊維を少なくとも一部に用いた生地からなることが好ましい。生地に吸湿性繊維を用いることにより、衣服外側への湿気の放出を助長し、吸湿性繊維を使用した部位近辺の湿度を低下させることができ、蒸れ感がより抑制された衣服となる。吸湿性繊維の具体例としては、ポリエステル系吸湿繊維、ポリアミド系繊維、ポリアクリル系繊維、レーヨン系繊維、アセテート系繊維、綿、麻、絹、ウールなどが挙げられるが、これらに限定されない。なかでも、ポリエステル系吸湿繊維やポリアミド系繊維は、機械的特性や耐久性に優れるため好ましい。 It is preferable that the clothing of the present invention is made of a fabric that uses hygroscopic fibers at least in part. By using hygroscopic fibers in the fabric, it is possible to promote the release of moisture to the outside of the garment, lowering the humidity near the area where the hygroscopic fibers are used, and resulting in clothes that are less stuffy. Specific examples of hygroscopic fibers include, but are not limited to, polyester hygroscopic fibers, polyamide fibers, polyacrylic fibers, rayon fibers, acetate fibers, cotton, linen, silk, and wool. Among these, polyester moisture-absorbing fibers and polyamide fibers are preferred because they have excellent mechanical properties and durability.

本発明の衣服は、吸湿性繊維の吸湿率差(△MR)が2.0~10.0%であることが好ましい。本発明における吸湿性繊維の吸湿率差(△MR)とは、実施例記載の方法で測定される値を指す。△MRとは、軽い運動後の衣服内温湿度を想定した温度30℃、湿度90%RHにおける吸湿率と、外気温湿度として温度20℃、湿度65%RHにおける吸湿率との差である。すなわち、△MRは吸湿性の指標であり、△MRの値が高いほど、発汗時の蒸れ感、べたつき感が軽減され、衣服の着用快適性が向上する。吸湿性繊維の△MRを好ましくは2.0%以上、より好ましくは3.0%以上、さらに好ましくは4.0%以上とすることにより、衣服内の蒸れ感やべたつき感を少なくすることができ、着用快適性に優れた衣服となる。また、吸湿性繊維の△MRを好ましくは10.0%以下、より好ましくは9.0%以下、さらに好ましくは8.0%以下とすることにより、生地や衣服を製造する際の工程通過性や取り扱い性が良好となり、使用時の耐久性にも優れる衣服となる。 In the clothing of the present invention, it is preferable that the moisture absorption rate difference (ΔMR) of the hygroscopic fibers is 2.0 to 10.0%. The moisture absorption rate difference (ΔMR) of hygroscopic fibers in the present invention refers to a value measured by the method described in Examples. ΔMR is the difference between the moisture absorption rate at a temperature of 30° C. and humidity of 90% RH, which assumes the temperature and humidity inside clothes after light exercise, and the moisture absorption rate at a temperature of 20° C. and humidity of 65% RH as outside temperature and humidity. That is, △MR is an index of hygroscopicity, and the higher the value of △MR, the less stuffy and sticky feeling caused by sweating, and the more comfortable the garment is to wear. By setting the ΔMR of the hygroscopic fiber to preferably 2.0% or more, more preferably 3.0% or more, and even more preferably 4.0% or more, it is possible to reduce the feeling of stuffiness and stickiness in clothes. The result is a garment that is highly comfortable to wear. In addition, by setting the ΔMR of the hygroscopic fiber to preferably 10.0% or less, more preferably 9.0% or less, and still more preferably 8.0% or less, process passability when manufacturing fabrics and clothes is improved. The resulting garment is easy to handle and has excellent durability during use.

本発明の衣服は、衣服内へ外気を取り込むための吸気口を少なくとも1つ有することが好ましい。ここで吸気口とは、通常の衣服が有する襟、袖、裾などの開口部ではなく、衣服内へ外気を取り込むために別途設ける、衣服の基本的な部位よりも通気度が高い部位のことである。このような吸気口を有していれば、衣服内へ外気を効率よく取り込むことができるため、暑熱感や蒸れ感を抑制することができ、着用快適性に優れた衣服となる。本発明の衣服において、吸気口の数ならびに吸気口の位置には特に制限がなく、着用感や意匠性等を損なわない範囲で適宜選択することができる。The garment of the present invention preferably has at least one air intake port for taking in outside air into the garment. The air intake port is not an opening in the collar, sleeves, hem, etc. that is found in normal garments, but a separate part that is provided to take in outside air into the garment and has a higher degree of breathability than the basic parts of the garment. If such an air intake port is present, outside air can be efficiently taken into the garment, thereby suppressing the feeling of heat and stuffiness, resulting in a garment with excellent wearing comfort. In the garment of the present invention, there is no particular restriction on the number and position of the air intake ports, and they can be appropriately selected within a range that does not impair the wearing comfort or design.

本発明の衣服に設けられる吸気口は、衣服を構成する基本的な部位(衣服本体)の生地よりも通気度の高い素材で構成されていることが好ましい。吸気口の通気度を衣服本体の生地よりも高くすることにより、効率的に衣服内に外気を取り込むことが可能となる。なお、吸気口の通気度は特に制限されないが、400cm/cm/s以上であることが好ましい。 It is preferable that the air inlet provided in the clothing of the present invention is made of a material having higher air permeability than the fabric of the basic part (garment body) of the clothing. By increasing the air permeability of the air inlet than the fabric of the main body of the garment, it becomes possible to efficiently draw outside air into the garment. Note that the air permeability of the intake port is not particularly limited, but is preferably 400 cm 3 /cm 2 /s or more.

本発明の衣服は、衣服内の空気を衣服外側へ排出するための排気口を有していてもよい。排気口も、通常の衣服が有する襟、袖、裾などの開口部ではなく、衣服内の空気を衣服外側へと排出するために前記吸気口に対応するように別途設ける、衣服の基本的な部位よりも通気度が高い部位のことである。このような排気口を有していれば、衣服内の換気を促進することができるため、暑熱感や蒸れ感を抑制することができ、着用快適性に優れた衣服となる。本発明の衣服において、排気口の数ならびに排気口の位置には特に制限がなく、着用感や意匠性等を損なわない範囲で適宜選択することができる。 The garment of the present invention may have an exhaust port for discharging air within the garment to the outside of the garment. Exhaust ports are not openings in the collar, sleeves, hem, etc. of normal clothing, but are a basic part of clothing that are provided separately to correspond to the air intake ports in order to exhaust the air inside the clothing to the outside of the clothing. This is a part that has higher air permeability than other parts of the body. If such an exhaust port is provided, ventilation within the garment can be promoted, so that the feeling of heat and stuffiness can be suppressed, resulting in a garment that is highly comfortable to wear. In the garment of the present invention, the number of exhaust ports and the position of the exhaust ports are not particularly limited, and can be appropriately selected within a range that does not impair wearability, design, etc.

本発明の衣服に設けられる排気口は、衣服の生地よりも通気度の高い素材で構成されていることが好ましい。排気口の通気度を衣服本体の生地よりも高くすることにより、衣服内の空気を効率的に衣服外側へと排出することが可能となる。なお、排気口の通気度は特に制限されないが、400cm/cm/s以上であることが好ましい。 The exhaust port provided in the garment of the present invention is preferably made of a material with higher air permeability than the fabric of the garment. By making the air permeability of the exhaust port higher than that of the fabric of the main body of the garment, it becomes possible to efficiently exhaust the air inside the garment to the outside of the garment. Note that the air permeability of the exhaust port is not particularly limited, but is preferably 400 cm 3 /cm 2 /s or more.

本発明の衣服は、少なくともファンとモーターとから構成される送風ファンユニットを具備していることが重要である。該送風ファンユニットによって衣服と身体との間に外気を取り込むことにより、衣服内に滞った空気を襟や袖などの開口部から排出することができるため、効率的に身体を冷却することが可能となる。 It is important that the garment of the present invention includes a blower fan unit that includes at least a fan and a motor. By drawing outside air between the clothes and the body using the fan unit, the air stagnant inside the clothes can be discharged through openings in the collar, sleeves, etc., making it possible to efficiently cool the body. becomes.

本発明の衣服に具備される送風ファンユニットは、搭載するファンがファン軸方向の略垂直方向に送風する遠心ファンもしくはブロアファンであるであることが好ましい。遠心ファンもしくはブロアファンを用いることにより、身体に対して略平行方向に指向性を有した外気を送風することが容易となり、効率よく身体を冷却することが可能となる。さらに、身体に対して略平行方向に送風することにより、身体に対して略垂直方向に送風した場合と比較して衣服が膨らみにくくなるため、意匠性に優れた衣服となる。 It is preferable that the fan installed in the ventilation fan unit included in the clothing of the present invention is a centrifugal fan or a blower fan that blows air in a direction substantially perpendicular to the axial direction of the fan. By using a centrifugal fan or a blower fan, it becomes easy to blow outside air with directivity in a direction substantially parallel to the body, making it possible to efficiently cool the body. Furthermore, by blowing air in a direction substantially parallel to the body, the clothes are less likely to swell compared to when the air is blowing in a direction substantially perpendicular to the body, resulting in clothes with excellent design.

本発明の衣服に具備される送風ファンユニットは、ファンの外径が10~60mmであることが好ましい。ファンの外径を好ましくは10mm以上、より好ましくは15mm以上、さらに好ましくは20mm以上とすることにより、外気を衣服内に送り込むのに十分な風量を得ることができる。また、ファンの外径を好ましくは60mm以下、より好ましくは55mm以下、さらに好ましくは50mm以下とすることにより、ファン駆動時の騒音が小さくなるとともに、送風ファンユニット本体を小さくすることができるため着用時に違和感の小さい送風ファンユニットとなる。 Preferably, the fan unit included in the clothing of the present invention has an outer diameter of 10 to 60 mm. By setting the outer diameter of the fan to preferably 10 mm or more, more preferably 15 mm or more, and even more preferably 20 mm or more, a sufficient amount of air can be obtained to blow outside air into the clothes. In addition, by setting the outer diameter of the fan to preferably 60 mm or less, more preferably 55 mm or less, and even more preferably 50 mm or less, the noise generated when the fan is driven is reduced, and the main body of the blower fan unit can be made smaller. This is a blower fan unit that sometimes feels strange.

本発明の衣服に具備される送風ファンユニットは、ファン軸方向の厚さが3~20mmであることが好ましい。ファン軸方向の厚さを好ましくは3mm以上、より好ましくは4mm以上、さらに好ましくは5mm以上とすることにより、外気を衣服内に送り込むのに十分な風量を得ることができる。また、ファン軸方向の厚さを好ましくは20mm以下、より好ましくは17mm以下、さらに好ましくは15mm以下とすることにより、送風ユニット本体を薄くすることができるため、着用時の違和感が小さくなり、着用快適性に優れた衣服となる。 The blower fan unit included in the clothing of the present invention preferably has a thickness of 3 to 20 mm in the fan axial direction. By setting the thickness in the axial direction of the fan to preferably 3 mm or more, more preferably 4 mm or more, and still more preferably 5 mm or more, a sufficient air volume to send outside air into the clothes can be obtained. In addition, by setting the thickness of the fan in the axial direction to preferably 20 mm or less, more preferably 17 mm or less, and still more preferably 15 mm or less, the main body of the blower unit can be made thinner, which reduces discomfort when worn. The result is clothing with excellent comfort.

本発明の衣服に具備される送風ファンユニットは、衣服や指先がファンに巻き込まれることを防止するため、吸気口と送風口を有したケースに収納されていることが好ましい。なお、ケースに収納される内蔵物は特に制限されないが、ファンとモーターのみを収納したものや、ファンとモーターに加え、バッテリー、電源スイッチなどを収納したものなどが挙げられる。なお、ケース内にバッテリーや電源スイッチが収納されない場合、両端部に接続端子を有する電源ケーブルなどの配線を介して、送風ファンユニットと接続されていることが好ましい。 The ventilation fan unit included in the clothing of the present invention is preferably housed in a case having an air intake port and a ventilation port in order to prevent clothing and fingertips from getting caught in the fan. There are no particular restrictions on the built-in items that can be stored in the case, but examples include cases that only contain a fan and motor, and cases that contain a battery, power switch, etc. in addition to the fan and motor. Note that when the battery and power switch are not housed in the case, it is preferable that they are connected to the blower fan unit via wiring such as a power cable having connection terminals at both ends.

本発明の衣服に具備される送風ファンユニットは、重量が200g以下であることが好ましい。重量を好ましくは200g以下、より好ましくは100g以下、さらに好ましくは50g以下とすることにより、着用時に重量感を感じにくく、着用快適性に優れた衣服となる。 It is preferable that the blower fan unit included in the clothing of the present invention has a weight of 200 g or less. By controlling the weight to preferably 200 g or less, more preferably 100 g or less, and even more preferably 50 g or less, the garment will not feel heavy when worn and will be comfortable to wear.

本発明の衣服は、衣服内の風に指向性を付与するための流路形成部を衣服内側に具備してなることが重要である。衣服内の風に指向性を付与するための流路形成部とは、上記送風ファンユニットから衣服内に送風された風の流れを特定方向に規制する、通風流路を形成するための部分である。本発明者らは、衣服内の蒸れ感や膨らみを抑制し、効率的に身体を冷却できる衣服について鋭意検討を重ねた結果、一定の通気度を有する生地からなる衣服に送風ファンユニットを具備させることに加え、衣服内の風に指向性を付与するための流路形成部を衣服内側に設けることにより、オフィスや家庭などの様々な着用シーンにおいて好適に用いることが可能な衣服となることを見出した。通常、通気度の高い衣服に送風ファンユニットを具備させた場合、衣服の膨らみや衣服内の蒸れ感を抑制できるものの、冷却すべき身体の部位に風が届く前に衣服外側に風が抜け出てしまうため、着用快適性に優れた衣服を得ることが困難である。この課題に対し、本発明では上述の通り、衣服内の風に指向性を付与するための流路形成部を上記衣服内側に設け積極的に通風流路を形成することにより、冷却すべき身体の部位に風を誘導することが可能となり、意匠性や着用快適性を飛躍的に向上させることに成功したのである。 It is important that the garment of the present invention is provided with a flow path forming section inside the garment for imparting directionality to the wind within the garment. The flow path forming part for imparting directionality to the wind inside the clothes is a part that forms a ventilation flow path that regulates the flow of the air blown into the clothes from the above-mentioned ventilation fan unit in a specific direction. be. The inventors of the present invention have conducted extensive research into clothing that can suppress stuffiness and bulges inside clothing and efficiently cool the body, and as a result, have equipped clothing made of fabric with a certain degree of air permeability with a blower fan unit. In addition, by providing a flow path forming part on the inside of the garment to give directionality to the wind inside the garment, we believe that the garment can be suitably used in a variety of wearing situations, such as at the office or at home. I found it. Normally, when clothes with high breathability are equipped with a fan unit, it is possible to suppress the swelling of the clothes and the feeling of stuffiness inside the clothes, but the wind escapes to the outside of the clothes before it reaches the parts of the body that need to be cooled. Because of this, it is difficult to obtain clothing that is comfortable to wear. In order to solve this problem, the present invention, as described above, provides a flow path forming part inside the clothing to give directionality to the air inside the clothing, and actively forms a ventilation flow path to cool the body to be cooled. This made it possible to direct wind to these areas, and succeeded in dramatically improving the design and wearing comfort.

以下、図1を用いて流路形成部について説明する。図1(a)は本発明の一実施形態を示す衣服における流路形成部の正面図であり、図1(b)はその側面図、図1(c)はその断面図である。 Hereinafter, the flow path forming section will be explained using FIG. 1. FIG. 1(a) is a front view of a flow path forming portion in a garment showing one embodiment of the present invention, FIG. 1(b) is a side view thereof, and FIG. 1(c) is a sectional view thereof.

図1に示す衣服においては、流路形成部としての凸状部1が一方向に延在している。すなわち、送風ファンユニット2の送風口幅と同程度の間隔に配置された凸状部1aおよび1bが衣服生地3に取り付けられており、かつ凸状部1aおよび1bは送風ファンユニット2の略送風方向に連続的に設けられている。なお、本発明において流路形成部は、衣服内の風に指向性を付与することができれば、必ずしも凸状の流路材で構成する必要はない。例えば衣服生地を断面袋状に縫製し、その内部にスタッフィング材を詰めることで凸状部を形成し流路形成部としてもよい。また、流路形成部を構成する凸状部の数は特に制限がないが、送風ファンユニットから送風される風を規制し通風流路を形成する観点から、衣服の大きさに応じて2本以上など複数本とすることが好ましい。 In the garment shown in FIG. 1, a convex portion 1 serving as a flow path forming portion extends in one direction. That is, the convex portions 1a and 1b are attached to the clothing fabric 3 and are arranged at an interval approximately equal to the width of the air outlet of the blower fan unit 2, and the convex portions 1a and 1b are arranged approximately at the same distance as the width of the air outlet of the blower fan unit 2. are provided continuously in the direction. In addition, in the present invention, the flow path forming portion does not necessarily need to be formed of a convex flow path material as long as it can impart directionality to the wind inside the clothing. For example, a convex portion may be formed by sewing clothing fabric into a cross-sectional bag shape and filling the inside with stuffing material to form a flow path forming portion. In addition, there is no particular limit to the number of convex portions that make up the flow path forming portion, but from the viewpoint of regulating the air blown from the ventilation fan unit and forming a ventilation flow path, two or more convex portions may be used depending on the size of the clothing. It is preferable to use a plurality of the above.

本発明の衣服において一方向に延在する凸状部1は、長さLが30~500mmであることが重要である。本発明における凸状部の長さLとは、実施例記載の方法で測定される値を指す。凸状部の長さLを30mm以上、好ましくは50mm以上、より好ましくは70mm以上とすることにより、衣服内の空気や湿気を効率よく衣服外側に排出することができ、蒸れ感や暑熱感が抑制された衣服となる。また、凸状部の長さLを500mm以下、好ましくは450mm以下、より好ましくは400mmとすることにより、身体と凸状部の接触による違和感が少なく着用快適性に優れた衣服となる。 In the garment of the present invention, it is important that the convex portion 1 extending in one direction has a length L of 30 to 500 mm. The length L of the convex portion in the present invention refers to a value measured by the method described in Examples. By setting the length L of the convex portion to 30 mm or more, preferably 50 mm or more, and more preferably 70 mm or more, air and moisture inside the clothes can be efficiently discharged to the outside of the clothes, reducing the feeling of stuffiness and heat. It becomes a restrained garment. Further, by setting the length L of the convex portion to 500 mm or less, preferably 450 mm or less, and more preferably 400 mm, the garment can be made to have excellent wearing comfort with less discomfort caused by contact between the body and the convex portion.

本発明の衣服に形成される凸状部1は、厚さTが3~20mmであることが好ましい。本発明における凸状部の厚さTとは、実施例記載の方法で測定される値を指す。凸状部の厚さTを好ましくは3mm以上、より好ましくは5mm以上、さらに好ましくは7mm以上とすることにより、衣服内に通風流路を形成することができるため、衣服内の空気を効率よく置換することができ、着用快適性に優れた衣服となる。また、凸状部の厚さTを好ましくは20mm以下、より好ましくは17mm以下、さらに好ましくは15mm以下とすることにより、身体と凸状部の接触による違和感が少なく着用快適性に優れ、かつ外観上凸状部が浮き出ることなく意匠性にも優れた衣服となる。 The thickness T of the convex portion 1 formed on the garment of the present invention is preferably 3 to 20 mm. The thickness T of the convex portion in the present invention refers to a value measured by the method described in Examples. By setting the thickness T of the convex portion to preferably 3 mm or more, more preferably 5 mm or more, and still more preferably 7 mm or more, it is possible to form a ventilation passage within the clothing, thereby efficiently discharging the air within the clothing. It can be used as a replacement for clothing and is highly comfortable to wear. In addition, by setting the thickness T of the convex portion to preferably 20 mm or less, more preferably 17 mm or less, and still more preferably 15 mm or less, there is less discomfort caused by contact between the body and the convex portion, and the wearability is excellent, and the appearance is excellent. The garment has an excellent design without the upper convex portion standing out.

本発明の衣服に形成される凸状部1は、幅Wが5~30mmであることが好ましい、本発明における凸状部の幅Wとは、個々の凸状部の幅であって、実施例記載の方法で測定された値を指す。凸状部の幅Wを好ましくは5mm以上、より好ましくは8mm以上、さらに好ましくは10mm以上とすることにより、身体の動きによって凸状部が倒れることを抑制でき、通風流路の形状を保つことが可能となる。また、凸状部の幅Wを好ましくは30mm以下、より好ましくは25mm以下、さらに好ましくは20mm以下とすることにより、身体との接触面積が小さくなり、着用時の違和感を抑制することができる。 It is preferable that the convex portion 1 formed on the garment of the present invention has a width W of 5 to 30 mm. The width W of the convex portion in the present invention is the width of each convex portion, and Refers to the value measured by the method described in the example. By setting the width W of the convex portion to preferably 5 mm or more, more preferably 8 mm or more, and even more preferably 10 mm or more, it is possible to suppress the convex portion from falling down due to body movements and maintain the shape of the ventilation channel. becomes possible. Further, by setting the width W of the convex portion to preferably 30 mm or less, more preferably 25 mm or less, and still more preferably 20 mm or less, the contact area with the body is reduced, and discomfort when worn can be suppressed.

また、本発明の衣服に形成される凸状部1は、複数本の凸状部から構成する場合、隣り合う凸状部の間隔を図1に示すように一定に保ってもよいが、位置によって変化させてもよい。図3に、複数本の凸状部の取り付け角度の概略説明図を示す。隣り合う凸状部1a、1bの間隔を位置によって変化させる場合、図3に示すように、送風口から離れるほど広くなるように取り付けることが好ましく、その取り付け角度A(隣り合う凸状部がなす角度)は20°以下であることが好ましい。凸状部の取り付け角度を好ましくは20°以下、より好ましくは10°以下、さらに好ましくは5°以下とすることにより、衣服内の風に指向性を付与できるため、効率よく身体を冷却することが可能となる。なお、隣り合う凸状部1a、1bが平行に取り付けられている場合の取り付け角度は0°であり、送風口から離れるほど隣り合う凸状部1a、1bの間隔が狭くなる場合の取り付け角度は負となる。よって、凸状部の取り付け角度の下限としては0°であることが好ましい。 Further, when the convex part 1 formed on the garment of the present invention is composed of a plurality of convex parts, the interval between adjacent convex parts may be kept constant as shown in FIG. It may be changed by FIG. 3 shows a schematic illustration of the mounting angles of the plurality of convex portions. When changing the distance between adjacent convex portions 1a and 1b depending on the position, it is preferable to install them so that the distance between adjacent convex portions 1a and 1b increases as the distance from the air outlet increases, as shown in FIG. The angle) is preferably 20° or less. By setting the attachment angle of the convex portion to preferably 20 degrees or less, more preferably 10 degrees or less, and even more preferably 5 degrees or less, it is possible to impart directionality to the wind inside the clothing, thereby efficiently cooling the body. becomes possible. Note that when the adjacent convex portions 1a and 1b are attached in parallel, the attachment angle is 0°, and when the distance between the adjacent convex portions 1a and 1b becomes narrower as the distance from the air outlet increases, the attachment angle is 0°. becomes negative. Therefore, it is preferable that the lower limit of the attachment angle of the convex portion is 0°.

実施例1~9で得られた衣服は、快適性、着用感、意匠性のいずれの評価においても良好な結果を有していることから、オフィスや家庭などの着用シーンにおいても好適に用いられる衣服となった。The garments obtained in Examples 1 to 9 achieved favorable results in the evaluations of comfort, fit, and design, making them suitable for use in settings such as the office and home.

一方、比較例1で得られた衣服は、用いられる生地の通気度が低いために衣服内の暑熱感および蒸れ感が抑制できず、快適性に劣る衣服となり、比較例2で得られた衣服は、用いられる生地の通気度が高いために風が衣服を通り抜けてしまい背中部に風が届かず、かつ衣服が薄く透けているため、快適性および意匠性に劣る衣服となった。比較例3で得られた衣服は、送風ファンユニットが取り付けられていないために衣服内の暑熱感および蒸れ感が抑制できず、快適性に劣る衣服となった。また比較例4で得られた衣服は流路形成部が設けられていないために冷却すべき身体の部位に風が当たらず、衣服内の暑熱感および蒸れ感が抑制できないため快適性に劣る衣服となった。比較例5で得られた衣服は、凸状部が多数あるものの連続形成されておらず、送風ファンユニットから送風された風が衣服内で拡散してしまい、衣服内の暑熱感および蒸れ感が抑制できないため快適性に劣る衣服となった。 On the other hand, the clothes obtained in Comparative Example 1 were less comfortable because the fabric used had low air permeability, so the feeling of heat and stuffiness inside the clothes could not be suppressed, and the clothes obtained in Comparative Example 2 Because the fabric used had high air permeability, the wind passed through the clothing and did not reach the back, and the clothing was thin and transparent, resulting in clothing that was inferior in comfort and design. Since the clothes obtained in Comparative Example 3 were not equipped with a blower fan unit, the feeling of heat and stuffiness inside the clothes could not be suppressed, resulting in clothes that were inferior in comfort. In addition, the clothing obtained in Comparative Example 4 does not have a flow path forming part, so the wind does not hit the parts of the body that should be cooled, and the feeling of heat and stuffiness inside the clothing cannot be suppressed, so the clothing is inferior in comfort. It became. Although the garment obtained in Comparative Example 5 has many convex portions, they are not continuous, and the wind blown from the fan unit diffuses within the garment, resulting in a hot and stuffy feeling inside the garment. The lack of control resulted in clothing that was less comfortable.

本発明の衣服は、衣服内の蒸れ感や暑熱感が抑制されるため衣服内環境を快適に保つことができ、かつ着用快適性および意匠性にも優れるため、高温および/または高湿の環境や、オフィスや家庭など快適性が必要とされる様々な着用シーンにおいて好適に用いることができる。The garment of the present invention maintains a comfortable environment inside the garment by suppressing stuffiness and heat sensation inside the garment, and also has excellent wearability and design, making it suitable for use in a variety of situations where comfort is required, such as in high temperature and/or high humidity environments, or in the office or at home.
