Description

  The present invention relates to leg wear for wearing during sleep.

  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.

  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.

JP 2005-68588 A

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  Next, the outer member 10 and the inner member 20 will be described in detail.

  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.

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} .

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.

  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.

  The surface or fiber of the outer member 10 preferably has an anti-pill function so as not to impair the appearance.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  The present invention is not limited to the above-described embodiment, and various modifications can be made.

  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.

  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.

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>

  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.

  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.

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>

  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.

  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.

  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.

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.
<Impressions of the monitor>

Moreover, about the present Example, the fitting evaluation at the time of sleep by 129 monitors was performed, and the impression was asked. An example of an impression is shown below.
・ I wrapped my feet with a soft warmth and I could sleep better than ever.
・ I was able to sleep in the morning without feeling uncomfortable.
・ I felt warm and relaxed.
-Anyway, it feels good and does not get cold.
・ When you put it on, your cold feet get warm quickly.
-Feels wrapped in a blanket up to your fingertips.
・ My feet were never really cold.
・ When my feet cool down, I couldn't sleep until my feet were warm, but this became warm immediately and I could sleep well.
・ Once you meet these socks, you can't let go.
From these results, it was possible to demonstrate that the sleep leg wear 1 according to the present invention can realize the suppression of cold feet and a good sleep.
