Description

本発明は、睡眠時に着用するためのレッグウェアに関するものである。   The present invention relates to leg wear for wearing during sleep.

睡眠は、疲労の回復や免疫細胞の活性化、自律神経のコントロールなど人間の生活において重要な役割を果たしていると言われている。それゆえ、睡眠の阻害は人体にとって様々な悪影響があるが、逆に快適な睡眠は健康に大きく寄与することが知られている。一方、女性においては、冷え性で悩む人が多く、特に足の冷えが睡眠の阻害要因となっていることも少なくない。この点について、足の冷えを抑えるために靴下を着用して睡眠する人もいるが、締め付けにより不快感を覚えたり、血行を阻害して逆効果を招いたりする。締付けのゆるい靴下を着用すると寝具の中でズレたり脱げ易くなってしまう。   Sleep is said to play an important role in human life, such as recovery from fatigue, activation of immune cells, and control of autonomic nerves. Therefore, although sleep inhibition has various adverse effects on the human body, it is known that comfortable sleep greatly contributes to health. On the other hand, many women are troubled by coldness, and in particular, the coldness of their feet is often an obstacle to sleep. In this regard, there are some people who sleep while wearing socks to suppress the coldness of the feet, but tightening may cause discomfort or inhibit blood circulation and cause adverse effects. Wearing loosely-tightened socks makes it easier to slip or take off in the bedding.

これらの点に関し、特許文献1には、足を締め付けることなく、かつ、ずれ落ち難い構造を有する靴下が開示されている。具体的には、足の立体形状に合わせて裁断した複数枚の布地を縫合し、特に踵上に縫合部を配置することにより、締め付けなくてもずれ落ち難くなるとしている。   With regard to these points, Patent Document 1 discloses a sock having a structure that does not tighten a foot and is difficult to slip off. Specifically, a plurality of fabrics cut in accordance with the three-dimensional shape of the foot are stitched, and in particular, a stitched portion is arranged on the heel, so that it is difficult to slip off without tightening.

特開2005−68588号公報JP 2005-68588 A

ところで、靴下は元来、日中の生活における皮膚の保護や保温を目的とする着用物であって、快適な睡眠を得るためものではないため、冷え性予防などのために日常履くような靴下や保温性のみを高めた靴下を履いたとしても快適な睡眠は得られないことが多い。すなわち、快眠を得るためには、脳に休息を与え、エネルギーの消費を防ぐために深部体温を低下させる必要があると一般的に言われているが、これらの靴下ではこの深部体温の低下が阻害されることがある。   By the way, socks are originally intended to protect the skin and keep warm in the daytime life, not to get comfortable sleep. Socks that you wear everyday to prevent coldness, Even if you wear socks that only have warmth, you will often not get a comfortable sleep. That is, it is generally said that in order to obtain a good sleep, it is necessary to give the brain a rest and to lower the deep body temperature in order to prevent the consumption of energy. May be.

そこで、本発明は、足を温めると共に、睡眠時の深部体温の低下を補助することが可能な睡眠用レッグウェアを提供することを目的としている。   Then, this invention aims at providing the leg wear for sleep which can assist the fall of the deep body temperature at the time of sleep while warming a leg | foot.

人体は、動静脈吻合(Arteriovenous Anastomoses:AVA)という血管を開大させることによって、効率よく深部体温を低下させられることが分かっている。この動静脈吻合は、細動脈と細静脈を短絡させるバイパスの役割を果たしており、睡眠時に開大させることによって、動脈血の流量の増加とともに皮膚温度が上昇し、皮膚表面から放熱することにより深部体温が低下する。本願発明者らは、鋭意検討を重ねた結果、動静脈吻合の開大を促進させることが可能であることを見出した。足部の動静脈吻合を開大させるためには、体表面の約20%を占める下腿部の平均皮膚温を上げることに加えて、リラックス状態にあること、すなわち、副交感神経の活動を高めることが重要であった。副交感神経の活動を高めるには、締め付け感や肌への刺激等のストレスを排除し、ゆったり感や快適な肌触りを与えることが効果的であるとされている。   It has been found that the human body can efficiently lower the deep body temperature by opening a blood vessel called arteriovenous anastomoses (AVA). This arteriovenous anastomosis acts as a bypass that shorts arterioles and venules. By opening them during sleep, the skin temperature rises with increasing arterial blood flow, and heat is released from the skin surface to deep body temperature. Decreases. As a result of intensive studies, the present inventors have found that it is possible to promote the opening of the arteriovenous anastomosis. In order to enlarge the arteriovenous anastomosis of the foot, in addition to raising the average skin temperature of the lower leg, which occupies about 20% of the body surface, being in a relaxed state, that is, increasing the activity of the parasympathetic nerve It was important. In order to enhance parasympathetic nerve activity, it is said that it is effective to eliminate stress such as tightness and irritation to the skin, and to give a relaxed feeling and comfortable touch.

そこで、本発明の睡眠用レッグウェアは、睡眠時に着用するための睡眠用レッグウェアであって、着用者の足を締め付けない内側部材と外側部材とを重ねた二重構造であり、内側部材の表面は起毛状をなし、外側部材は、内側部材より高いドレープ性を有し、かつ、内側部材より滑らかな表面を有することを特徴とする。   Therefore, the sleep leg wear of the present invention is a sleep leg wear for wearing during sleep, and has a double structure in which an inner member and an outer member that do not tighten a wearer's foot are overlapped, The surface is raised, and the outer member has a higher draping property than the inner member and has a smoother surface than the inner member.

この睡眠用レッグウェアによれば、内側部材の表面が起毛状をなしているので、着用時に冷たさを感じることなく、足を温めることができるとともに、快適な肌触りを得ることができる。   According to this leg wear for sleep, since the surface of the inner member is raised, the feet can be warmed without feeling cold when worn, and a comfortable touch can be obtained.

また、足を締め付けない部材であるので、着用したまま就寝しても不快感がない。更に、外側部材のドレープ性が高く、かつ、表面が滑らかであるので、しなやかで柔らかく、滑らかな肌触りを得ることができる。その結果、この睡眠用レッグウェアを手に取り着用するまで、すなわち睡眠前から、快適な肌触りを手に感じることにより、副交感神経の活動を高めることができる。   Moreover, since it is a member which does not clamp | tighten a leg, even if it goes to bed with wearing, there is no discomfort. Furthermore, since the drapeability of the outer member is high and the surface is smooth, it is possible to obtain a soft touch that is supple and soft. As a result, the parasympathetic nerve activity can be enhanced by feeling a comfortable touch in the hand until the leg wear for sleeping is worn and worn, that is, before sleeping.

このように、内側部材により平均皮膚温を上昇させ、外側部材により睡眠前より副交感神経の活動を高めるので、動静脈吻合の開大を促進させ、深部体温の低下を補助することができる。その結果、快眠を得ることができる。   Thus, the average skin temperature is increased by the inner member, and the parasympathetic nerve activity is increased by the outer member before sleep. Therefore, the opening of the arteriovenous anastomosis can be promoted, and the lowering of the deep body temperature can be assisted. As a result, a good sleep can be obtained.

上記した外側部材は、0.7デニール以下のマイクロファイバー繊維からなることが好ましい。これによれば、外側部材のドレープ性を高くし、かつ、表面を滑らかにすることができる。すなわち、しなやかで柔らかく、滑らかな肌触りを有する外側部材を得ることができる。その結果、この睡眠用レッグウェアを手に取り着用するまで、すなわち睡眠前から、快適な肌触りを手に感じることにより、副交感神経の活動を高めることができる。   The outer member described above is preferably made of microfiber fibers of 0.7 denier or less. According to this, the drapeability of the outer member can be increased and the surface can be smoothed. That is, an outer member that is supple, soft, and has a smooth feel can be obtained. As a result, the parasympathetic nerve activity can be enhanced by feeling a comfortable touch in the hand until the leg wear for sleeping is worn and worn, that is, before sleeping.

上記した内側部材の起毛は、毛足が10mm〜70mmのマイクロファイバー繊維からなり、内側部材の起毛密度は、概ね200g/m〜500g/mであることが好ましい。これによれば、着用時の冷たさを低減し、温かさを得ることができる。また、内側部材の基布と着用者の肌との間に空気層を形成することができ、保温性を高めることができる。更には、締め付けを抑えるとともに、快適な肌触りを得ることができる。 Brushed inner member described above, haired consists microfiber fibers 10Mm~70mm, brushed density of the inner member is preferably approximately 200g / m 2 ~500g / m 2 . According to this, the coldness at the time of wearing can be reduced and warmth can be obtained. Moreover, an air layer can be formed between the base fabric of an inner member and a wearer's skin, and heat retention can be improved. Furthermore, it is possible to suppress tightening and obtain a comfortable touch.

上記した睡眠用レッグウェアは、着用者の脚から脱げることを防止するための係止部材であって、非伸縮性を有する当該係止部材を更に備えることが好ましい。これによれば、睡眠中の寝返り等でも脱げたりズレたりすることなく、効果を持続することができる上、当該係止部材が非伸縮性であることにより、結ぶ位置等で締め付け具合を自ら調節することができるため好適である。   The above-mentioned sleeping leg wear is a locking member for preventing the leg wear from being removed from the wearer's leg, and preferably further includes the locking member having non-stretchability. According to this, it is possible to maintain the effect without taking off or shifting even when turning over during sleep, etc., and the locking member is non-stretchable, so that the tightening degree is adjusted by the tying position etc. This is preferable.

上記した睡眠用レッグウェアは、足底部は滑り止め機能を有することが好ましい。これによれば、足底部が滑り止め機能を有しているので、睡眠時以外に着用しても、着用したまま室内を比較的安全に歩くことができる。   In the above-described sleeping leg wear, it is preferable that the sole has a non-slip function. According to this, since the sole part has a non-slip function, even if it wears other than at the time of sleep, it can walk in the room comparatively safely with wearing.

本発明によれば、睡眠用レッグウェアにおいて、足を温めると共に副交感神経の活動を高めることにより、動静脈吻合を開大させることができ、睡眠時の深部体温の低下を補助することができる。その結果、快眠を得ることができる。   ADVANTAGE OF THE INVENTION According to this invention, an arteriovenous anastomosis can be expanded by warming a leg and heightening the activity of a parasympathetic nerve in sleep legwear, and can assist the fall of the deep body temperature at the time of sleep. As a result, a good sleep can be obtained.

以下、図面を参照して本発明の好適な実施形態について詳細に説明する。なお、各図面において同一又は相当の部分に対しては同一の符号を附すこととする。   DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals.

図1は、本発明の実施形態に係る睡眠用レッグウェアを示す斜視図で有り、図2は、図1に示すつま先部を拡大して示す側面図である。また、図3は、図1に示す足底部を裏側から示す図であり、図4は、図1のIV-IV線に沿う断面の一部を示す部分断面図である。この睡眠用レッグウェア1は、足の冷えを抑え、快眠を得るために睡眠時に着用するためのものであって、外側部材10と内側部材20とを重ねた二重構造となっている。   1 is a perspective view showing a leg wear for sleep according to an embodiment of the present invention, and FIG. 2 is an enlarged side view showing a toe portion shown in FIG. 3 is a view showing the sole portion shown in FIG. 1 from the back side, and FIG. 4 is a partial cross-sectional view showing a part of a cross section taken along line IV-IV in FIG. The sleeping leg wear 1 is for wearing during sleep in order to prevent the feet from getting cold and to obtain a good sleep, and has a double structure in which the outer member 10 and the inner member 20 are overlapped.

外側部材10は、足の脛部及び足の甲部を覆う脛・甲部材11と、足の脹脛部を覆う脹脛部材12と、足の裏部を覆う足底部材13とから成る。脛・甲部材11と脹脛部材12とは足の側部における縫着部14で縫着されており、脛・甲部材11と足底部材13とは足の側部における縫着部15で縫着されている。また、脹脛部材12と足底部材13とは、踵部における縫着部16で縫着されている。靴下編機等で筒状に編み立てることによってレッグウェアとして編成可能であるが、前述の通り不要な締め付け感が生じるため好適ではない。   The outer member 10 includes a shin / top member 11 that covers the shin of the foot and the instep of the foot, a calf member 12 that covers the calf of the foot, and a sole member 13 that covers the back of the foot. The shin / top member 11 and the calf member 12 are sewn at the sewn portion 14 at the side of the foot, and the shin / top member 11 and the sole member 13 are sewn at the sewn portion 15 at the side of the foot. It is worn. Moreover, the calf member 12 and the sole member 13 are sewn by the sewn part 16 in the heel part. Although it can be knitted as legwear by knitting it in a cylindrical shape with a sock knitting machine or the like, it is not preferable because an unnecessary tightening feeling is generated as described above.

同様に、内側部材20は、足の脛部及び足の甲部を覆う脛・甲部材21と、足の脹脛部を覆う脹脛部材22と、足の裏部を覆う足底部材23とから成る。脛・甲部材21と脹脛部材22とは足の側部における縫着部24で縫着されており、脛・甲部材21と足底部材23とは足の側部における縫着部25で縫着されている。また、脹脛部材22と足底部材23とは、踵部における縫着部26で縫着されている。また、内側部材20は、足の挿入口部において折り返してなる折返部27を有しており、折返部27と外側部材10とは、縫着部17で縫着されている。   Similarly, the inner member 20 includes a shin / top member 21 that covers the shin of the foot and the instep of the foot, a calf member 22 that covers the calf of the foot, and a sole member 23 that covers the back of the foot. . The shin / top member 21 and the calf member 22 are sewn at the sewn portion 24 at the side of the foot, and the shin / top member 21 and the sole member 23 are sewn at the sewn portion 25 at the side of the foot. It is worn. Further, the calf member 22 and the sole member 23 are sewn by a sewn portion 26 in the heel portion. Further, the inner member 20 has a folded portion 27 that is folded back at the insertion opening of the foot, and the folded portion 27 and the outer member 10 are sewn together by a sewn portion 17.

縫着部14〜16,17,24〜26の縫着方法としては、肌触りがよいM字縫い等が用いられることが好ましい。また、縫着しやすくするため、外側部材10と内側部材20とは、全面又は部分的に接着されていることが好ましい。   As a sewing method for the sewing portions 14 to 16, 17, and 24 to 26, it is preferable to use M-shaped sewing or the like that is comfortable to the touch. Moreover, in order to make it easy to sew, it is preferable that the outer member 10 and the inner member 20 are bonded to each other entirely or partially.

これらの外側部材10及び内側部材20は、着用者の足を締め付けないように伸縮性の低いものを使用し、適度にゆとりのある着用感が得られるよう裁断・縫製を行っている。   These outer member 10 and inner member 20 are made of a material having low elasticity so as not to tighten the wearer's foot, and are cut and sewn so as to obtain a moderately comfortable wearing feeling.

本実施形態では、図2に示すように、足底部材13は、いせ込み手法を用いて、足底部30がつま先部32に突出するように立体的に形成されている。これにより、縫着部15が足底部30の接地面より上方に位置するので、歩行時の着用者のつまずき等を防止することができる。   In the present embodiment, as shown in FIG. 2, the sole member 13 is three-dimensionally formed so that the sole portion 30 protrudes from the toe portion 32 using an urging method. Thereby, since the sewing part 15 is located above the ground-contact surface of the sole part 30, a wearer's tripping at the time of a walk, etc. can be prevented.

また、図3に示すように、足底部30にはすべり止め34が設けられている。本実施形態では、すべり止め34は、ゴム部材であり、足底部30に複数設けられている。これにより、睡眠時以外に着用しても、着用したまま室内を比較的安全に歩くことができる。   Further, as shown in FIG. 3, a slip stopper 34 is provided on the sole portion 30. In the present embodiment, the slip stopper 34 is a rubber member, and a plurality of the slip stoppers 34 are provided on the sole portion 30. Thereby, even if it wears other than at the time of sleeping, it can walk indoors comparatively safely with wearing.

次に、外側部材10及び内側部材20について詳細に説明する。   Next, the outer member 10 and the inner member 20 will be described in detail.

図4に示すように、内側部材20における脛・甲部材21、脹脛部材22、及び、足底部材23は、基布28と、基布28から起毛する起毛29からなっている。なお、この内側部材20は、毛布のように基布の所要の点位置より繊維の束が放出する構造のボア調の生地を使用している。このようにして、内側部材20における足が接触する側の表面及び折返部27の表面は起毛状をなすこととなる。   As shown in FIG. 4, the shin / top member 21, the calf member 22, and the sole member 23 of the inner member 20 are composed of a base cloth 28 and raised portions 29 raised from the base cloth 28. The inner member 20 uses a bore-like fabric having a structure in which a bundle of fibers is discharged from a required point position of the base fabric, such as a blanket. Thus, the surface of the inner member 20 on the side where the foot comes into contact and the surface of the folded portion 27 are raised.

内側部材20の起毛29は、毛足が約10mm〜70mmのマイクロファイバーポリエステル繊維からなり、その起毛密度は概ね200g/m〜500g/mである。マイクロファイバー繊維は、他の素材で代用することも可能である。但し、合成繊維についてはアクリルやナイロン等が考えられるが、接触温感の点でポリエステルが有用である。また、天然繊維について、ウール等の動物繊維は繊度が太く着用時にチクチク感があるので好適ではなく、綿などの植物繊維は速乾性に乏しいため好適ではない。加えて、内側部材20の起毛29の毛足は約15mm〜30mmであると更に好ましく、その起毛密度は約300g/m〜400g/mであると更に好ましい。 Brushed 29 of the inner member 20, haired consists microfiber polyester fibers of approximately 10Mm~70mm, the raising density is approximately 200g / m 2 ~500g / m 2 . The microfiber fibers can be substituted with other materials. However, for synthetic fibers, acrylic, nylon, and the like are conceivable, but polyester is useful in terms of contact temperature. As for natural fibers, animal fibers such as wool are not suitable because they are thick and have a tingling sensation when worn, and plant fibers such as cotton are not suitable because they are poor in quick-drying properties. In addition, more preferred more preferably the bristles brushed 29 of the inner member 20 is about 15Mm~30mm, when the raising density is about 300g / m 2 ~400g / m 2 .

起毛29の毛足が約10mm以上であり、その起毛密度が概ね200g/10以上であることにより、着用時の冷たさを低減し、温かさを得ることができる。また、基布28と着用者の肌との間に空気層を形成することができ、保温性を高めることができる。更には、マイクロファイバー繊維を用いることにより、肌触りを向上することができる。なお、起毛29の毛足が約70mmを超えると、好ましくは約30mmを超えると、ごそごそするなど着用感に影響が出るおそれがあり、起毛密度が約500g/mを超えると、好ましくは約400g/mを超えると、肌触りが硬く感じるおそれがある。 When the raised hair 29 has a hair foot of about 10 mm or more and a raising density of about 200 g / 10 2 or more, the coldness during wearing can be reduced and warmth can be obtained. In addition, an air layer can be formed between the base fabric 28 and the wearer's skin, and heat retention can be improved. Furthermore, the touch can be improved by using microfiber fibers. In addition, when the hair foot of the raising 29 exceeds about 70 mm, and preferably exceeds about 30 mm, there is a possibility that the feeling of wear may be affected. For example, when the raising density exceeds about 500 g / m 2 , When it exceeds 400 g / m 2 , the touch may feel hard.

一方、外側部材10は、約0.7デニール以下の超極細マイクロファイバーアクリルにより編成されている。外側部材10には、約0.4デニール以下の超極細マイクロファイバーアクリルが用いられることが更に好ましい。このようにして、外側部材10は、内側部材20より高いドレープ性及び柔軟性を有し、かつ、内側部材20より滑らかな表面を有することとなる。これにより、しなやかで柔らかく、滑らかな肌触りを得ることができる。なお、外部部材10も、内部部材20と同様に他の素材で代用することが可能であるが、同じ問題が生じる可能性がある。   On the other hand, the outer member 10 is knitted with ultra-fine microfiber acrylic of about 0.7 denier or less. More preferably, the outer member 10 is made of an ultra-fine microfiber acrylic of about 0.4 denier or less. In this way, the outer member 10 has higher drape and flexibility than the inner member 20 and a smoother surface than the inner member 20. As a result, a supple, soft and smooth feel can be obtained. The external member 10 can be replaced with another material similarly to the internal member 20, but the same problem may occur.

この外側部材10の表面又は繊維には、外観を損なわないよう抗ピル機能が備わっていることが好ましい。   The surface or fiber of the outer member 10 preferably has an anti-pill function so as not to impair the appearance.

また、足の挿入口部には、着用者の脚から脱げたりズレたりすることを防止するための係止部材40が設けられている。係止部材40は、着用者が自ら締め付け具合を調整することができる非伸縮性のものが好ましく、本実施形態では梵天紐であり、内側部材20の折返部27に設けられている。   Further, a locking member 40 is provided at the insertion opening of the foot to prevent it from being removed from or slipping off the wearer's leg. The locking member 40 is preferably a non-stretchable member that allows the wearer to adjust the tightening degree by himself / herself. In this embodiment, the locking member 40 is a bran string and is provided on the folded portion 27 of the inner member 20.

ここで、図5に、人の深部体温(直腸温)の平均的な周期を示す。図5では、横軸を時間(時)、縦軸を深部体温(℃)とし、昼の12時から翌日の起床までの深部体温の推移を連続2日間、実線で表わしている。この図5から分かるように、深部体温は、入睡前後から下がり始め、午前4時頃に最も低くなり、目覚める前に上昇し始める。睡眠時の深部体温の低下は、脳に休息を与え、エネルギーの消費を防ぐために行われるものであると一般的に考えられており、これが妨げられると快眠が阻害されることとなる。   Here, FIG. 5 shows an average cycle of human deep body temperature (rectal temperature). In FIG. 5, the horizontal axis represents time (hours), the vertical axis represents deep body temperature (° C.), and the transition of deep body temperature from 12:00 noon to the next day's wakeup is represented by a solid line for two consecutive days. As can be seen from FIG. 5, the deep body temperature starts to decrease before and after falling asleep, becomes the lowest at around 4 am, and starts to increase before waking up. The decrease in deep body temperature during sleep is generally considered to be performed in order to give the brain rest and prevent energy consumption, and if this is prevented, pleasant sleep is inhibited.

また、入眠直後約3時間において深い眠りに入り易く、その後は眠りが浅くなる傾向がある。この入眠直後約3時間まで、すなわち快眠につながる深い眠りの間の深部体温の低下が快眠にとって重要とされている。   Moreover, it is easy to enter deep sleep about 3 hours immediately after falling asleep, and after that, there is a tendency for sleep to become shallow. It is important for a good sleep to decrease the deep body temperature until about 3 hours immediately after falling asleep, that is, during a deep sleep that leads to a good sleep.

人体は、動静脈吻合(Arteriovenous Anastomoses:AVA)という血管を開大させることによって、効率よく深部体温を低下させられることが分かっている。図6は、動静脈吻合の模式図である。この図6における矢印は血流を示す。動静脈吻合は、手、足、顔にのみ局在するものであり、毛細血管の手前において動脈と静脈との間にバイパスの役割を果たすものである。動静脈吻合の直径は、毛細血管の直径の約10倍であり、動静脈吻合の血流は毛細血管の血流の約1万倍となるといわれている。この動静脈吻合を開くことによって、動脈血の流量の増加とともに皮膚温度が上昇し、放熱することにより深部体温が低下する。   It has been found that the human body can efficiently lower the deep body temperature by opening a blood vessel called arteriovenous anastomoses (AVA). FIG. 6 is a schematic diagram of an arteriovenous anastomosis. The arrows in FIG. 6 indicate blood flow. The arteriovenous anastomosis is localized only on the hands, feet, and face, and plays a role of bypass between the artery and vein before the capillaries. The diameter of the arteriovenous anastomosis is about 10 times the diameter of the capillaries, and the blood flow of the arteriovenous anastomosis is said to be about 10,000 times the blood flow of the capillaries. By opening this arteriovenous anastomosis, the skin temperature rises with increasing arterial blood flow, and the deep body temperature falls by releasing heat.

この動静脈吻合を開くための条件は、第1に平均皮膚温を上昇させること、第2にリラックス状態にあること、すなわち、副交感神経の活動を高めることである。なお、平均皮膚温の上昇は、脳への温熱入力を経て動静脈吻合の開大へと繋がると考えられている。   The conditions for opening this arteriovenous anastomosis are firstly to increase the average skin temperature and secondly to be in a relaxed state, that is, to increase parasympathetic activity. The increase in average skin temperature is thought to lead to the expansion of arteriovenous anastomosis via thermal input to the brain.

本実施形態の睡眠用レッグウェア1によれば、内側部材20の内表面が起毛状をなしているので、着用時に冷たさを感じることなく、足を温めることができる。更に、不要な締め付けを抑え、快適な触感とともに快眠を得ることができる。   According to the sleeping leg wear 1 of this embodiment, since the inner surface of the inner member 20 is raised, the feet can be warmed without feeling cold when worn. Furthermore, unnecessary tightening can be suppressed, and a pleasant sleep can be obtained with a comfortable tactile sensation.

また、部材10,20は、足を締め付けない伸縮性の低い部材であるので、着用したまま就寝しても不快感がない。更に、外側部材10のドレープ性及び柔軟性が高く、かつ、表面が滑らかであるので、しなやかで柔らかく、滑らかな肌触りを得ることができる。その結果、この睡眠用レッグウェアを手に取り着用するまで、すなわち睡眠前から、快適な肌触りを手に感じることにより、副交感神経の活動を高めることができる。   Moreover, since the members 10 and 20 are members having low elasticity that do not tighten the legs, there is no uncomfortable feeling even if they sleep while wearing. Furthermore, since the drapeability and flexibility of the outer member 10 are high and the surface is smooth, it is possible to obtain a soft touch that is supple and soft. As a result, the parasympathetic nerve activity can be enhanced by feeling a comfortable touch in the hand until the leg wear for sleeping is worn and worn, that is, before sleeping.

このように、内側部材20により平均皮膚温を上昇させ、外側部材10により睡眠前より副交感神経の活動を高めるので、入眠後の早いタイミングから動静脈吻合の開大を促進させ、深部体温の低下を補助することができる。その結果、入眠直後約3時間において深い眠りに入り易く、快眠を得ることができる。   Thus, the average skin temperature is increased by the inner member 20, and the parasympathetic nerve activity is increased by the outer member 10 before sleep. Therefore, the opening of the arteriovenous anastomosis is promoted from the early timing after falling asleep, and the deep body temperature is decreased. Can assist. As a result, it is easy to enter deep sleep about 3 hours immediately after falling asleep, and a good sleep can be obtained.

なお、本発明は上記した本実施形態に限定されることなく種々の変形が可能である。   The present invention is not limited to the above-described embodiment, and various modifications can be made.

本実施形態では、脛及び脹脛を覆う長さの睡眠用レッグウェアを例示したが、睡眠用レッグウェアの長さはこれに限定されるものではない。例えば、着用者の好みに応じて踝近傍までのショートタイプであってもよいし、膝上までのロングタイプであってもよい。   In the present embodiment, the sleep leg wear covering the shin and the calf is illustrated, but the length of the sleep leg wear is not limited thereto. For example, depending on the wearer's preference, a short type up to the vicinity of the heel may be used, or a long type up to the knee may be used.

また、本実施形態では、係止部材として梵天紐を例示したが、係止部材はこれに限定されるものではない。例えば、マジックテープやベルトなど、伸縮性を有さず足を締め付けないものであれば様々な態様が適用可能である。   Moreover, in this embodiment, although the bran string was illustrated as a locking member, a locking member is not limited to this. For example, various modes such as a magic tape and a belt can be applied as long as they do not have elasticity and do not tighten a foot.

図1に示す本発明の実施形態の睡眠用レッグウェア1を実施例として製作し、以下の評価を行った。なお、本実施例では、上記した睡眠用レッグウェア1において、内側部材20の起毛は毛足約15mmのマイクロファイバーとし、起毛密度を約300g/mとした。また、外側部材10には、約0.4デニールの超極細マイクロファイバーを使用した。
<接触温冷感>
The sleep leg wear 1 of the embodiment of the present invention shown in FIG. 1 was manufactured as an example, and the following evaluation was performed. In the present embodiment, in the above-described sleeping leg wear 1, the raised hair of the inner member 20 was a microfiber with a hair foot of about 15 mm, and the raised density was about 300 g / m 2 . The outer member 10 was made of ultra-fine microfibers of about 0.4 denier.
<Contact thermal sensation>

この評価では、着用した瞬間に温かさを感じる度合いを検証するために接触温冷感について、実施例と比較例との対比評価を行った。   In this evaluation, in order to verify the degree of feeling warmth at the moment of wearing, a comparative evaluation between the example and the comparative example was performed on the thermal contact feeling.

ここで、本実施例に対して対比を行った比較例は、出願人の商品であって、靴下として用いられるものである。比較例1は、綿及びアクリルを含む合成繊維によって一般的な靴下用編機で編成された一重構造の靴下であり、比較例2は、カシミヤを含む糸によって同じく一般的な靴下用編機で編成された一重構造の靴下である。   Here, the comparative example which compared with the present Example is an applicant's goods, and is used as socks. Comparative Example 1 is a sock having a single structure knitted by a general sock knitting machine with synthetic fibers including cotton and acrylic, and Comparative Example 2 is also a general sock knitting machine using yarn containing cashmere. It is a knitted single sock.

評価結果を図7に示す。縦軸に接触温冷感(w/cm)とし、各サンプルの値の大きさを棒グラフの高さで示した。図7における接触温冷感の値が小さいほど、接触時に冷たさを感じることなく、温かいと感じることとなる。図7によれば、本実施例は、比較例1,2に比べ、接触時に冷たさを感じることなく、温かいと感じることがわかる。これは、内側部材20の表面を起毛状とし、起毛として毛足約15mmのマイクロファイバーポリエステル繊維を用い、起毛密度を約300g/mとしたことによるものと考えられる。
<睡眠時の着用者の皮膚温度及び血流量>
The evaluation results are shown in FIG. The vertical axis represents the contact thermal sensation (w / cm 2 ), and the value of each sample is indicated by the height of the bar graph. As the value of the contact thermal sensation in FIG. 7 is smaller, it feels warmer without feeling cold at the time of contact. According to FIG. 7, it can be seen that the present embodiment feels warmer than the first and second comparative examples without feeling cold at the time of contact. This is considered to be because the surface of the inner member 20 was raised, the microfiber polyester fiber having a hair foot of about 15 mm was used as the raising, and the raising density was about 300 g / m 2 .
<Skin temperature and blood flow of wearer during sleep>

この評価では、睡眠時の着用者の皮膚温度及び血流量の推移について、被験者3名による試着評価を行った。この評価では、実施例又は上記比較例1を試着したとき、並びに裸足のときの比較評価を行った。   In this evaluation, a trial evaluation by three subjects was performed on the transition of the skin temperature and blood flow of the wearer during sleep. In this evaluation, comparative evaluation was performed when trying on the example or the comparative example 1 as well as when barefoot.

被験者Aは、25歳女性で中度の冷え性であり、被験者Bは、24歳女性で中度の冷え性である。被験者Cは、30歳男性で低度の冷え性である。   Subject A is a 25-year-old woman with moderate coldness and Subject B is a 24-year-old woman with moderate coldness. Subject C is a 30-year-old male with a low degree of coldness.

被験者A〜Cの評価結果を図8〜10にそれぞれ示す。図8〜10は、ともに横軸を時間(0分は就床)、左縦軸を皮膚温度、右縦軸を血流量とし、睡眠中の皮膚温度と血流量の変化を計測した。また、皮膚温度・血流量ともに母指部を計測した。図8〜10において、曲線51a,51bがそれぞれ本実施例を着用したときの皮膚温度、血流を示し、曲線52a,52bがそれぞれ比較例1を着用したときの皮膚温度、血流を示し、曲線53a,53bがそれぞれ裸足のときの皮膚温度、血流を示す。   The evaluation results of subjects A to C are shown in FIGS. 8-10, the horizontal axis represents time (0 minutes is bedtime), the left vertical axis represents skin temperature, and the right vertical axis represents blood flow, and changes in skin temperature and blood flow during sleep were measured. The thumb was measured for both skin temperature and blood flow. 8-10, curves 51a and 51b show the skin temperature and blood flow when wearing the present embodiment, respectively, curves 52a and 52b show the skin temperature and blood flow when wearing Comparative Example 1, respectively. Curves 53a and 53b show the skin temperature and blood flow when barefoot, respectively.

図8〜10によれば、本実施例では、比較例1及び裸足に比べ、入睡から約90分の間に血流量を増大させるとともに、比較的早くに皮膚温度を高めること、すなわち放熱させられることがわかる。この結果から、本実施例では、比較例1及び裸足に比べ、動静脈吻合の開大を促進させ、深部体温の低下をより効果的に補助することができることがわかる。この要因は、内部部材20による平均皮膚温の上昇、並びに外側部材10のドレープ性が高く、かつ、表面が滑らかであるので、比較例1及び裸足に比べ、よりしなやかで柔らかく、滑らかな肌触りを得ることができ、その結果、手に取り着用するまで、すなわち睡眠前から、快適な肌触りを手に感じることにより、より効果的に副交感神経の活動を高めることができたことによるものと考えられる。また、血流量の増大は、足の冷えが抑えられたことを示すものとも考えられる。
<モニタの感想>
According to FIGS. 8 to 10, in this embodiment, compared to Comparative Example 1 and bare feet, the blood flow is increased approximately 90 minutes after falling asleep, and the skin temperature is increased relatively quickly, that is, the heat is dissipated. I understand that. From this result, it can be seen that, in this example, compared with Comparative Example 1 and bare feet, the opening of the arteriovenous anastomosis can be promoted and the lowering of the deep body temperature can be assisted more effectively. This is because the average skin temperature is increased by the inner member 20 and the draping property of the outer member 10 is high, and the surface is smooth. Therefore, compared to Comparative Example 1 and barefoot, the softness and softness are smoother. As a result, it is considered that the parasympathetic nerve activity was able to be increased more effectively by feeling a comfortable touch in the hand until it was attached to the hand, that is, before sleeping. . An increase in blood flow is also considered to indicate that the cooling of the feet has been suppressed.
