Technical Field

The present disclosure relates to a garment covering at least a portion of an upper limb or a lower limb, and more particularly to a garment worn at bedtime for promoting comfortable sleep.

Background

Recently, as health consciousness has been heightened, the importance of sleep has increased. Sleep is said to recover physical and mental fatigue and enhance immune function, playing an important role in maintaining health. Therefore, clothes for promoting comfortable sleep are welcomed.

In order to achieve so-called deep sleep, it is important to first fall asleep as early as possible. In order to fall asleep as early as possible, it is necessary to eliminate obstructive factors such as cold as early as possible, convert autonomic nerves from sympathetic nerves to parasympathetic nerves, and relax the body as early as possible.

When the human body is in a state close to sleep, the human body has a mechanism of expanding AVA (Arteriovenous anastomosis) blood vessels and promoting blood flow in order to lower the core body temperature. AVA blood vessels are blood vessels connecting arteries and veins, and are present only locally in the hands, feet, and face. When the AVA blood vessel expands, arterial blood flows at once, the skin temperature rises, and the heat dissipation from the peripheral region rapidly increases, whereby the deep body temperature rapidly decreases. As a result, sleep starts.

Problems to be solved by the invention

Thus, if the AVA blood vessel expands, the fingertip temperature of the hand and foot where the blood flow easily stagnates rises at the time of the AVA vasoconstriction, and heat dissipation starts. However, if heat is not easily released from the fingertips of hands and feet, the core body temperature does not drop, and discomfort is felt due to excessive warmth in the near future. Therefore, if excessive heat is not released from the tip of the finger or its vicinity, it may wake up from sleep due to discomfort. In the present disclosure, a portion where the finger of the tip portion of the hand or foot is located is referred to as a fingertip, and a portion "corresponding to the portion where the finger of the tip portion of the hand or foot is located" on the clothing is referred to as a "toe portion".

Therefore, in order to promote comfortable sleep, it is important to promote early onset of sleep by warming the portions of relatively little subcutaneous fat and muscle and susceptible to cold to eliminate cold, and at the same time, to promote the release of heat from the tip of the finger or its vicinity.

Patent document 1 discloses, as clothing to be worn at bedtime, socks that are constituted by sock-tube portions from the heel to the position above the knee, without the toe portion, and that promote venous circulation to avoid or reduce foot edema without causing stuffiness in the fingertips.

Further, patent document 2 discloses a foot sock in which a plurality of pieces of cloth are cut and sewn in accordance with the three-dimensional shape of a foot, and an opening is provided at a toe portion, as clothing to be worn at bedtime, so that the retention of the heel is high, the heat retaining property of the foot is good, and the air permeability is improved.

However, the sock described in patent document 1 is intended to avoid foot edema, and since the tip portion of the finger is open, the heat of the tip portion of the finger cannot be preserved, and early sleep cannot be promoted by eliminating cold as early as possible.

The foot sock described in patent document 2 has a rib top (Crew) length at which the upper end of the foot sock is located between the calf and the ankle. However, when the toe tip becomes cold, even if only the foot and its adjoining parts are kept warm, cold blood circulates, and thus it is not enough to eliminate the cold as early as possible.

Patent document 2 also discloses: in order to improve the heat retaining property of the foot, a fabric made of fibers having a heat generating property is used as the fabric.

However, if the fiber having the heat generating property is used for the entire foot sock regardless of the level of the heat generating property, the heat may be excessively preserved. Therefore, a comfortable sleep may not be obtained.

An aspect of the present disclosure is made in view of the above-mentioned problems, and an object thereof is to provide a garment: cold is eliminated by warming the peripheral part which is difficult to warm and the position where subcutaneous fat and muscle are relatively less, and the tip part of the finger or the part adjacent to the tip part of the finger is opened to release heat.

Means for solving the problem

In order to solve the above-described problems, an aspect of the present disclosure provides a garment that covers at least a portion of at least one of a lower limb and an upper limb, the garment including a plurality of heat retaining portions having higher heat retaining properties than other portions, the plurality of heat retaining portions including knee portions, heel portions, and a toe portion of the lower limb, and at least one of a wrist portion, an elbow portion, and a fingertip portion of the upper limb, and a heat dissipating portion having higher air permeability than other portions of the plurality of heat retaining portions, the toe portion or a portion adjacent to the fingertip portion.

Detailed Description

(embodiment mode 1)

An embodiment of the present disclosure will be described below with reference to fig. 1 to 6. Hereinafter, a case where the clothing provided in the present embodiment is a footlet (sock) will be described as an example.

Fig. 1 is an external view schematically showing a foot sock 10 according to the present embodiment.

The footlet 10 shown in fig. 1 is a footlet having a thigh (thigh) length from a fingertip of a lower limb to a part of a thigh. In addition, a part of the thigh specifically refers to the upper half of the thigh (i.e., the upper half of the portion between the pelvis and the knee). The footlet 10 has a knee upper portion 1, a knee portion 2, a shin portion 3, a heel portion 4, a foot body portion 5, and a fingertip portion 6. In addition, a heat dissipation portion 51 having higher air permeability than other portions is provided in a part of the foot portion 5.

The lap 1 is provided with a welt portion 11, and the welt portion 11 is provided with an opening portion, i.e., a welt 12, for inserting a lower limb into the foot sock 10. The welt 12 is provided at the upper end of the foot sock 10.

On the other hand, the fingertip portion 6 is provided at the lower end of the footlet 10. The fingertip portion 6 is formed in a bag shape to wrap the entire fingertip of the foot. The heat dissipation portion 51 is provided at a portion adjacent to the fingertip portion 6 in the foot body portion 5. The heat dissipation portion 51 is preferably formed as a mesh portion, for example, and when the heat dissipation portion 51 is a knitted fabric, it is preferably knitted by, for example, an uneven knit (mesh knitting). When the heat dissipation portion 51 is woven by an uneven weave so that the heat dissipation portion 51 is in a mesh shape, for example, air permeability can be improved, and heat at the finger tip portion 6 and the vicinity thereof can be effectively dissipated from the heat dissipation portion 51 to the outside. Of course, the heat dissipation portion 51 may have any structure as long as it can improve air permeability as compared with other portions. In the present embodiment, although the heat dissipation portion 51 is formed by the uneven knitting, the air permeability of the heat dissipation portion 51 can be improved by increasing the size of stitches or making the thickness of knitting yarns finer. Further, a mesh-like material may be sewn to the portion of the foot portion 5 adjacent to the fingertip portion 6. The heat dissipation portion 51 includes a instep portion and a sole portion, and is preferably provided in a circumferential shape (ring shape). In the example shown in fig. 1, the heat dissipation portion 51 is illustrated as an example in which it is provided in a circumferential shape so as to surround the leg portion 5 along the toe portion 6. By forming the heat dissipation portion 51 in this manner, heat can be efficiently dissipated. The area of the heat dissipation portion 51 is not particularly limited as long as it is located in the region of the foot portion 5. However, the larger the area of the heat dissipation portion 51, the higher the heat dissipation effect, and the more easily the cooling. Therefore, the heat dissipation part 51 is preferably provided in the region 1/3 to 1/2 on the toe part 6 side of the leg part 5.

The length of the foot body portion 5 and the fingertip portions 6 is set such that the fingertip portions 6 can cover the fingertips when the heel portion 4 is attached to the heel of the foot worn by the footwear 10. Thus, the fingertip portion 6 covers the upper and lower faces of the third joint of the foot (i.e., the fingertip third joint).

The third joint of the foot (fingertip) in the present disclosure is a joint called a middle toe joint or MP joint and formed to connect a fingertip end portion of a middle foot bone and a heel end portion of a phalanx. The upper surface of the third joint is a skin surface corresponding to the instep side of the third joint, and the lower surface of the third joint is a skin surface corresponding to the sole side of the third joint.

The knee part 2, the heel part 4, and the fingertip part 6 are heat retaining parts having higher heat retaining properties than the other parts. Thus, the foot sock 10 has a plurality of heat retaining portions having higher heat retaining properties than other portions.

In order to fall asleep as early as possible, it is necessary to eliminate obstructive factors such as cold as early as possible. In this case, the fingertip is most cold, and it is important to warm the fingertip as soon as possible.

However, when the tip of the foot is cold, for example, even if only the tip of the toe is warmed like the fingertip 6, the cold blood circulates, and thus it is not enough to quickly eliminate the cold. In order to eliminate the cold as early as possible, it is effective to warm not only the tip of the toe but also a portion from the center of the body to the tip of the toe, in which subcutaneous fat and muscle that are particularly liable to be cooled are relatively small (specifically, knee, heel). This enables blood from the center of the body to be transported to the toe tip in a warm state. In addition, the larger the area covering the foot, the more warm is felt. However, on the other hand, the portions of the feet other than the knees, heels, and fingertips are covered with subcutaneous fat and muscles as compared with the knees, heels, and fingertips, and thus are difficult to be cooled.

Therefore, the portions other than the knee, the heel, and the fingertip do not need the heat retaining property as the knee, the heel, and the fingertip. Further, if a material such as a fiber having high heat generating property is used in a high content in the entire portion of the footlet 10 in contact with the lower limb to warm the entire lower limb, the warm is excessively preserved. Therefore, for comfortable sleep, it is important to warm the lower limbs by partially warming them, rather than excessively warming them. Here, partially warming the lower limbs means specifically warming only the peripheral parts which are difficult to warm and the positions where subcutaneous fat and muscles are relatively small. In other words, for comfortable sleep, it is important to warm the parts including the knees, heels, and fingertips to a proper temperature.

Based on this sleep mechanism, the foot sock 10 warms the peripheral part which is hard to warm and the position where the subcutaneous fat and the muscle which are easy to cool are relatively less (corresponding to the knee, the heel, and the finger tip in the lower limb), thereby eliminating the cold and promoting the early sleep. On the other hand, the footgear 10 can promote comfortable sleep by radiating heat from the toe portion 6 and the vicinity thereof.

In addition, the knee 2 preferably covers at least the region corresponding to the patella. The heel portion 4 preferably covers the heel bone end portion on the opposite side to the fingertip and its vicinity, and more preferably further covers the lower end of the achilles tendon connected from the upper end of the heel bone and its vicinity. This can reduce cold in particular. In the embodiment, the knee upper 1 represents a portion covering a region above the knee joint. The shin portion 3 indicates a portion covering a region between the knee joint and the ankle joint. The shaft portion 5 is a portion covering a lower area than the ankle joint, and indicates a portion other than the heel portion 4 and the fingertip portion 6.

The fabric of the footgear 10 may be a knitted fabric (knit fabric) or a woven fabric. However, in order to provide the fitting property, and to prevent the wearer from being hampered by excessive tightening, the fabric of the footlet 10 preferably has a degree of stretchability as a whole to follow at least the movement during normal sleep without causing stress to the wearer. Therefore, the footgear 10 is preferably a knitted fabric in terms of ease of obtaining appropriate stretch and fit of stitches.

The heat retaining portion may be made of any material and may have any structure as long as it has higher heat retaining property than the other portions. However, the heat-retaining portion is preferably knitted with a knitting yarn having heat-retaining properties. Examples of the woven yarn having heat retaining properties include a woven yarn containing fibers having heat absorbing properties, a woven yarn having heat insulating properties, a woven yarn containing fibers retaining heat retaining properties by far infrared rays, and a temperature-sensitive processed yarn having temperature sensitivity. Examples of the fibers having hygroscopic heat-generating properties include acrylic ester-based fibers, wool, rayon, and the like. Examples of the woven yarn having heat insulation properties include a hollow yarn and a bulked yarn. As the woven yarn having a heat retaining property maintained by far infrared rays, for example, a woven yarn containing a mixed fiber of far infrared ceramics is cited. Examples of the temperature-sensitive processed yarn include a woven yarn formed by adhering a capsaicin component to a fiber. That is, the heat retaining property mentioned here includes any physical property or structure that generates heat, heat insulation, and a temperature sensation as described above, but is not limited thereto, and means all the properties that can prevent the covered portion from being cooled and keep warm.

In the heat-retaining portions (knee portion 2, heel portion 4, and fingertip portion 6), the total value of the heat-retaining values W of the materials contained in the knitting yarns for knitting the respective heat-retaining portions is preferably in the range of 12.5 to 50.0, and more preferably in the range of 25.0 to 50.0. The above-mentioned heat retention value W represents: the official moisture regain of the material contained in the knitting yarn used for knitting each heat retention part is multiplied by the content ratio of the material contained in the knitting yarn when the content of the material contained in the knitting yarn is 100 wt% and the content ratio of the material is 1.0.

That is, the heat retaining value W represents the heat retaining property of the material, and is defined as a heat retaining value W ═ a × B. In the above equation, a is a official moisture regain (%) of a material contained in a knitting yarn for knitting each heat retention part, and B is a content ratio of the material contained in the knitting yarn when the content of the material in the knitting yarn is 100% and the content ratio of the material is 1.0.

When the above material is a moisture-absorbing heat-generating fiber, A represents a official moisture regain (%) of the moisture-absorbing heat-generating fiber. B represents a content ratio of the hygroscopic heat-generating fibers contained in the braided yarn when the content of the hygroscopic heat-generating fibers in the braided yarn is 100 wt% and the content ratio of the hygroscopic heat-generating fibers is 1.0.

Hereinafter, for example, a case where a knitting yarn for knitting any of the heat-retaining portions is a blended yarn of an acrylic fiber and a polyester will be specifically described as an example. When the official moisture regain of the acrylic ester fiber as the heat-generating and moisture-absorbing fiber was 50% and the content of the acrylic ester fiber in the woven yarn was 50% by weight (content ratio was 0.5), the insulation value W of the acrylic ester fiber in the heat-retaining portion was 25. And, when the official moisture regain of the polyester is 0.4% and the content of the polyester in the knitting yarn is 50% by weight (content ratio is 0.5), the heat retaining value W of the polyester in the heat retaining portion is 0.2. Therefore, in this case, the total value of the heat retaining values W of the materials contained in the knitting yarn used for knitting the heat retaining portion (the sum of the heat retaining values W of the materials) is 25+0.2 to 25.2.

When the heat retaining portion is knitted with the knitting yarn having the total value of the heat retaining value W exceeding 50.0, the possibility of disturbing comfortable sleep due to excessive heat increases. In addition, when the footgear 10 provided with the heat retaining portion knitted with such a knitting yarn is worn for a long time, the possibility of damage to the skin (dryness or low-temperature burn) increases. Therefore, the total value of the heat retaining value W is preferably within the above range.

In addition, the total value of the heat retaining value W of the materials contained in the knitting yarns used to knit the portions (the knee upper portion 1, the shin portion 3, and the foot body portion 5) of the footgear 10 other than the heat retaining portion is preferably less than 12.5 in order to avoid excessive heat retention in the portions other than the heat retaining portion.

For example, a case where a knitting yarn for knitting a portion other than the heat retaining portion is a blended yarn of rayon and silk will be specifically described as an example. When the official moisture regain of the rayon is 11% and the rayon content in the knitting yarn is 50% (content ratio is 0.5), the insulation value W of the rayon in the portion other than the insulation portion is 5.5. When the official moisture regain of silk is 11% and the content of silk in the knitting yarn is 50% by weight (content ratio is 0.5), the heat retaining value W of silk in the portion other than the heat retaining portion is 5.5. Therefore, in this case, the total value of the heat retaining values W of the materials contained in the knitting yarn for knitting the portion other than the heat retaining portion (the sum of the heat retaining values W of the materials) is 5.5+5.5 — 11.0.

A table showing a list of the heat retention values W obtained from the combination of the official moisture regain a of the material contained in the knitting yarn and the content ratio of the material contained in the knitting yarn is shown in table 1.

[ Table 1]

Table 2 shows an example of combinations of the heat retaining portion and specific materials in portions other than the heat retaining portion. However, table 2 is only one example of a combination of specific materials, and is not limited to the combination shown in table 2.

[ Table 2]

As described above, the knitting yarn for knitting the heat retaining portion is not particularly limited as long as it has heat retaining properties. However, in order to warm the heat-retaining portion efficiently and to eliminate coldness as quickly as possible, a woven yarn containing an acrylic ester fiber having hygroscopic heat-generating properties is suitably used as the woven yarn. The number (thickness) of the knitting yarn can be appropriately selected from the general suitable number of the knitting yarns in accordance with the number of needles and the number of the knitting machine.

As the acrylic ester-based fiber having hygroscopic heat generating properties used in the present embodiment, an acrylic ester-based fiber having a official moisture regain of 35% or more is preferable, and an acrylic ester-based fiber having a official moisture regain of 50% or more is more preferable, in terms of effectively warming the heat-retaining portion. In addition, the plurality of heat-retaining portions are preferably knitted with a knitting yarn containing the acrylic ester fiber.

In addition, in order to suppress the unevenness of the partial heat retaining performance and to make the heat retaining performance uniform in the woven yarn, the content of the acrylate fiber in the woven yarn is preferably 25% or more. In order to reduce stress caused by a difference in warmth and maintain production efficiency, it is preferable that each of the heat-insulating portions is knitted with the same knitting yarn.

The higher the content of the same material in the woven yarn, the more uniformly the properties of the material can be exerted. On the other hand, as the content is lower, uniformity of the properties of the material in the knitting yarn is impaired, and there is a possibility that the properties of the knitting yarn are uneven. Therefore, by keeping the content of the acrylic fiber in the braided yarn at 25% or more, the performance of the acrylic fiber can be substantially uniformly exhibited. In addition, acrylate-based fibers are known to have a higher official moisture regain than other materials. When the acrylic fiber is blended with other materials, it is relatively easy to produce a blended yarn having a total value of the heat retention value W within the above numerical range.

By using a blended yarn containing, for example, 50% by weight of an acrylic ester-based fiber having a official moisture regain of 50% and the remaining 50% by weight of a polyester, for example, in the knitting yarn for knitting the heat-insulating portion, the heat-insulating portion can be warmed more effectively by utilizing high hygroscopic heat generation property.

Fig. 2 is a developed view of the knitted fabric of the footlet 10 shown in fig. 1.

As shown in fig. 2, the footlet 10 is knitted in a continuous tubular shape from the welt 12 to the fingertip portion 6 (tip end of the fingertip portion) by, for example, a circular knitting machine.

For example, the knit structure of the knee upper 1 is a single yarn knit with elastic. In addition, the single yarn knitting is a knitting method of knitting with one yarn. The knitting structure of the shank portion 5 excluding the shin portion 3 and the heat radiating portion 51 is a plain knitting structure, and the knitting structure of the heat radiating portion 51 is an uneven knitting (mesh knitting). The knee portion 2 is configured by forming a stitch line (gore line) in a V-shape, the heel portion 4 is configured by extending the heel, and the fingertip portion 6 is configured by forming a stitch line in a V-shape, and covers the fingertip portion in a large area.

In addition, in the knee 2, the heel 4, and the fingertip 6, which are the heat retaining portions, a widening area is provided for knitting the heel by reciprocating rotation of the knitting machine so as to reliably cover the spherical curved surfaces of the knee, the heel, and the fingertip and to follow the movement during sleep. Thereby, these heat insulating portions are three-dimensionally woven. The stitch area is provided by forming a stitch line GL in a V-shape. In addition, the fingertip portion 6 is provided by forming a stitch line GL of different lengths in a V-shape so as to wrap the fingertip. However, the present embodiment is not limited to this, and a Y-shaped or multi-branched seam line GL may be formed in the heat retaining portion, or a long seam line GL may be provided linearly.

Further, yarns having high heat retaining properties may be partially inserted only into portions corresponding to the knee portion 2, the heel portion 4, and the fingertip portion 6 without using the reciprocating rotation of the knitting machine.

The fingertip 6 is located farthest from the heart at the site covered by the three heat-retaining portions, and the blood flow tends to be slow, so that the site tends to feel cold. Therefore, the tip portion 6 preferably has a higher heat retaining force than the other heat retaining portions. Here, the fingertip portion 6 is preferably designed to be thicker than the other heat retaining portions by increasing the number of knitting yarns. In order to further improve the heat retaining property, the fingertip portion 6 may be formed into a loop structure having a bulky structure with a loop-like stitch.

The cylinder diameter (diameter of the cylinder) of the circular knitting machine is preferably larger than the cylinder diameter (3.75 to 4.0 inches) of a general circular knitting machine for knitting foot socks. The cylinder diameter of a circular knitting machine is the diameter of the cylinder that contributes to the completion of knitting. By making the diameter of the circular knitting machine larger than 4.0 inches, the foot socks 10 can be provided with soft and gentle tightening and stretching properties. In the present embodiment, a circular knitting machine having a cylinder diameter of 5.0 inches is used as the circular knitting machine. This makes it possible to obtain the comfortable cloth foot sock 10 that does not interfere with relaxation, and as a result, a more comfortable wearing feeling that does not interfere with sleep can be obtained.

However, the footgear 10 may be knitted using a circular knitting machine having a cylinder diameter of 3.75 inches, for example, as long as it does not have a strong tightening force to prevent sleep. As a method of adjusting the tightening feeling when using such a normal needle cylinder, for example, a method of using an elastic yarn having low stretchability as the back layer yarn or reducing the insertion amount of the elastic yarn may be considered.

As the material of the top layer yarn, natural touch is emphasized, and for example, natural fibers such as cotton and silk are used. However, the material of the top layer yarn is not particularly limited as long as a softer hand is emphasized and a skin touch that does not disturb sleep can be obtained, and a material such as a blended yarn of cotton and modal, a blended yarn of rayon and silk, or the like can be used.

In addition, the material of the inner layer yarn is also not particularly limited. In the inner layer Yarn, for example, FTY (filament twisted Yarn) can be used.

In the present embodiment, as the knitting yarn, a 30-count single yarn woven by blending 50 wt% of acrylic fiber and 50 wt% of polyester is used, and as the back yarn, 30/150FTY is used. The weaving yarn used was a textile yarn of 10 single yarns of 100 wt% cotton, and the inner yarn used was 30/75FTY, except for the heat-retaining portion. 30/150FTY refers to a FTY of polyester coated with 150 denier polyester over a 30 denier elastomeric yarn. 30/75FTY refers to FTY in which a polyester of 75 denier is covered with an elastomeric yarn of 30 denier.

In the footlet 10 of the present embodiment, since a cylinder having a cylinder diameter of 5.0 inches is used, soft fitting properties are obtained. Further, a knitting machine having 84 needles is used according to the number of surface layer yarns, but a knitting machine having 208 needles may be suitably selected for a surface layer yarn of 30 single yarns, for example.

In addition, the lap 1 covering the thigh is particularly preferably of comfortable construction. In particular, the welt portion 11 of the lap 1 is preferably reduced in stress by tightening as much as possible so as not to hinder the loosening. In the footlet 10, the portion above the upper end of the knee portion 2 (specifically, the portion from the upper end of the knee portion 2 to the welt 12) is preferably weaker than the tightening force of the shin portion 3.

Therefore, for example, the toe portion 11 is preferably knitted with an embossing weave. However, the welt portion 11 may be knitted by other knitting methods as long as the fastening portion is loose, and may be knitted by a sinker method in which, for example, all the yarns are caught by loop hooks of sinkers to form a large stitch.

(modification example)

As described above, in the present embodiment, the length of the footlet 10 is set to be long enough to cover the thigh of the thigh. However, the length may be as long as it covers the entire surface of the knee, and may be a length from the fingertip to the upper part of the knee, that is, a length of the upper part of the knee. However, since the larger the area covering the lower limbs (feet), the more easily the feet feel warm, the effect of eliminating cold as early as possible is easily obtained by setting the length of the footgear 10 to be long and the length of the thighs.

In fig. 1, a case where the heat dissipation portion 51 is provided in the foot portion 5 adjacent to the fingertip portion 6 is illustrated as an example. However, the present embodiment is not limited thereto. For example, a heat dissipation portion may be provided in the fingertip portion 6 adjacent to the foot portion 5.

Although not shown, a structure for pressing or stimulating the acupuncture points (acupoints) effective for improving cold may be provided on the footlet 10.

For example, it is said that pressing or stimulating the three-yin crossing located at the upper part of the inner side of the ankle has an effect of improving cold, and the cold can be effectively suppressed by providing a structure for pressing or stimulating the three-yin crossing when worn.

Therefore, as a structure for pressing or stimulating the triple-yin crossing, for example, a circular loop knitting portion having a diameter of about 4cm may be provided at a position corresponding to the triple-yin crossing (a portion just above the medial malleolus apex by the width of 4 fingers) when worn, using a heat insulating material having a heat insulating effect. Thus, when the footlet 10 is worn, the thermal stimulation can be applied to the Sanyinjiao to improve the cold. Further, it is preferable that the attachment of the portion of the leg portion 3 surrounding the terry knitted portion is improved to such an extent that the fastening feeling is not generated in the leg portion 3, and the terry knitted portion can be held at the triple-knitting position. The shape of the terry knitting portion may be arbitrary. The heat insulating material may be, for example, a hygroscopic heat generating material such as wool or acrylic fiber, or a temperature sensitive processing material using capsaicin, but is not limited thereto.

(embodiment mode 2)

Other embodiments of the present disclosure will be described below with reference to fig. 3 to 5. In addition, for convenience of description, members having the same functions as those described in embodiment 1 are denoted by the same reference numerals, and description thereof is not repeated. Note that, needless to say, the present embodiment may be modified in the same manner as embodiment 1.

Fig. 3 is an external view of the foot sock according to the present embodiment.

The heat dissipation portion may be an opening through which the fingertip can be exposed. Therefore, the footlet 10 may further have an opening portion capable of exposing the fingertips as a heat radiating portion. In the footlet 10 shown in fig. 3, instead of the mesh portion provided as the heat radiating portion 51 in the foot portion 5, the fingertip portion 6 is provided with an opening portion 61, and the opening portion 61 has an exposure hole 62 capable of exposing a fingertip as the heat radiating portion. Except for this point, the footlet 10 provided in the present embodiment is the same as the footlet 10 provided in embodiment 1.

According to the present embodiment, the foot socks 10 can be partially taken off from the fingertip portions 6 by providing the exposure port 62 in the fingertip portions 6. In the example shown in fig. 3, the exposure port 62 is provided on the instep side (upper surface side) of the fingertip portion 6. By providing the exposure port 62 on the instep side, the operation of exposing the fingertip (the operation of removing the fingertip by hand or the operation of removing the toe tip) can be easily performed. By thus projecting and exposing a part of the fingertip from the exposure port 62, heat of the fingertip can be promptly released.

Fig. 4 is a perspective view of a main portion of the footlet 10 shown in fig. 3. Fig. 4 shows a view 1011 showing a state where the opening portion 61 is folded so that the edge of the exposure port 62 is overlapped with the opening portion 61 of the footlet 10 shown in fig. 3, and the exposure port 62 is closed. Fig. 4 shows a view indicated by reference numeral 1012 in a state where a part of the fingertip 6 (a part closer to the fingertip side than the exposure port 62) of the footlet 10 shown in fig. 3 is rolled up to expose a part of the fingertip.

The toe portion 6 preferably covers at least one of the upper and lower faces of the third joint of the foot. The exposure port 62 may have a size that allows at least a part of a fingertip to be exposed, but is preferably sized so that the fingertip can be pulled out of the exposure port 62 by pulling down the fingertip portion 6. Here, the "at least a part of the fingertip" specifically means at least a part of the plurality of toes. When the fingertip 6 is pulled down and the fingertip is pulled out from the exposure port 62, it is not necessary to completely expose all 5 toes from the exposure port 62. However, the exposure port 62 is preferably sized to allow a part (fingertip) of all 5 toes to protrude.

The toe portion 6 has a length capable of covering at least a third joint from the front end of the foot (i.e., the front end of the fingertip) to the foot (fingertip) when the footlet 10 is worn. In the present embodiment, the opening portion 61 is preferably provided with an exposure port 62 on the distal end side (fingertip side) of the third joint of the foot (fingertip). According to the present embodiment, as shown by reference numeral 1011 in fig. 4, in the state where the footgear 10 is worn, at least the third joint of the foot (fingertip) can be covered when the opening portion 61 is folded so that the edge portion of the exposure port 62 overlaps. Therefore, the fingertips can be effectively exposed while maintaining the minimum heat retaining property.

The exposure port 62 is preferably formed in a position and a shape such that the fingertip is not unintentionally exposed by slight friction with bedding or the like in the initial stage of wearing the foot sock 10 (in other words, during a period from when the user sleeps to when the fingertip is intentionally exposed).

Fig. 5 is a development view of the knitted fabric of the footlet 10 shown in fig. 3 and 4.

As shown in fig. 5, the footlet 10 is knitted in a continuous tubular shape from the welt 12 to the exposure port 62 (in other words, the tip of the open hole portion 61) by, for example, a circular knitting machine.

For example, the knitting structure of the knee upper portion 1 is a single yarn knitting including an elastic band, the knitting structures of the shin portion 3 and the foot portion 5 are plain stitch structures, and the knitting structure of the opening portion 61 is a plain stitch structure including an elastic band. In addition, the knee portion 2 is configured to form a stitch line in a V-shape, and the heel portion 4 is configured to extend. The finger tip portion 6 except the opening portion 61 is formed in a V-shaped arrangement to form a patchwork line so as to wrap the finger tip portion in a large area.

In addition, similarly to embodiment 1, in order to reliably cover the spherical curved surfaces of the knees, heels, and fingertips and to follow the movement during sleep, the knee 2, heel 4, and fingertip 6, which are heat retaining parts, are provided with a widening area which is generally used for knitting the heel by the reciprocating rotation of the knitting machine. Thereby, these heat insulating portions are three-dimensionally woven. The stitch area is provided by forming a stitch line GL in a V-shape. In addition, the fingertip portion 6 is provided by forming a stitch line GL of different lengths in a V-shape so as to wrap the fingertip. However, as in embodiment 1, this embodiment is not limited to this, and a Y-shaped or multi-branched seam line GL may be formed on the heat retention portion, or a long seam line GL may be provided linearly.

Further, yarns having high heat retaining properties may be partially inserted only into portions corresponding to the knee portion 2, the heel portion 4, and the finger tip portion 6 without using the reciprocating rotation of the knitting machine.

As described in embodiment 1, the fingertip 6 is located farthest from the heart at the site covered by the three heat-retaining portions, and the blood flow tends to be slow, so that the site tends to feel cold. Therefore, the tip portion 6 preferably has a higher heat retaining force than the other heat retaining portions. Therefore, as described in embodiment 1, the fingertip portion 6 is preferably designed to be thicker than the other heat-retaining portions by increasing the number of knitting yarns or the like. In order to further improve the heat retaining property, the fingertip portion 6 may be formed into a loop structure having a bulky structure with a loop-like stitch.

Further, as in embodiment 1, the cylinder diameter (diameter of the cylinder) of the circular knitting machine preferably has a diameter (3.75 to 4.0 inches) larger than that of a cylinder of a general circular knitting machine for knitting foot socks. The cylinder diameter of a circular knitting machine is the diameter of the cylinder that contributes to the completion of knitting. By making the diameter of the circular knitting machine larger than 4.0 inches, the foot socks 10 can be provided with soft and gentle tightening and stretching properties as in embodiment 1. In the present embodiment, a circular knitting machine having a cylinder diameter of 5.0 inches is also used as the circular knitting machine. This makes it possible to obtain the comfortable cloth foot sock 10 that does not interfere with relaxation, and as a result, a more comfortable wearing feeling that does not interfere with sleep can be obtained.

However, the footgear 10 may be knitted using a circular knitting machine having a cylinder diameter of 3.75 inches, for example, as long as it does not have a strong tightening force to prevent sleep. As a method of adjusting the tightening feeling when using such a normal needle cylinder, as described in embodiment 1, for example, a method of using an elastic yarn having low stretchability as the back layer yarn or reducing the insertion amount of the elastic yarn may be considered.

As in embodiment 1, the material of the top layer yarn is preferably natural fibers such as cotton and silk, for example, because natural skin touch is important. However, the material of the top layer yarn is not particularly limited as long as a softer hand is emphasized and a skin touch that does not disturb sleep can be obtained, and a material such as a blended yarn of cotton and modal, a blended yarn of rayon and silk, or the like can be used.

Further, as described in embodiment 1, the material of the inner layer yarn is also not particularly limited. In the inner layer yarn, for example, FTY may be used. However, in the present embodiment, in order to facilitate exposure of fingertips during sleeping, a yarn (stretch nylon) having lower stretchability and lower tightening force than other regions is used as the inner layer yarn in the fingertip portion 6. However, the present embodiment is not limited to this, and the finger tip portion 6 may use FTY having a normal binding force as the inner layer yarn.

In this embodiment, as in embodiment 1, a 30-count single yarn woven yarn obtained by blending 50 wt% of an acrylate fiber and 50 wt% of polyester is used as the knitting yarn of the heat retention section. The inner layer yarn of the heat-retaining part other than the fingertip part 6 was 30/150 FTY. The inner yarn of the heat-retaining portion of the toe portion 6 is, as described above, an elastic nylon. For the knitting yarn other than the heat-insulating part, a textile yarn of 10 count single yarn of 100 wt% cotton was used, and 30/75FTY was used for the back yarn. In the footlet 10 of the present embodiment, since a cylinder having a cylinder diameter of 5.0 inches is used, soft fitting properties are obtained. Although a knitting machine having 84 needles is used depending on the number of surface yarns, for example, a knitting machine having 208 needles may be appropriately selected for a surface yarn of 30 single yarns.

Further, as described in embodiment 1, the lap 1 covering the thigh preferably has a more comfortable structure. In particular, the welt portion 11 of the lap 1 is preferably reduced in stress by tightening as much as possible so as not to inhibit loosening. In the footlet 10, the portion above the upper end of the knee portion 2 (specifically, the portion from the upper end of the knee portion 2 to the welt 12) is preferably weaker than the tightening force of the shin portion 3.

Therefore, as in embodiment 1, for example, the toe portion 11 is preferably knitted with an uneven knit. However, the welt portion 11 may be knitted by other knitting methods as long as the tightening is loose, and may be knitted by a sinker method, for example.

(modification example)

Fig. 6 is an external view schematically showing a footlet 10 according to a modification of the present embodiment.

In embodiments 1 and 2, a case where the footlet 10 is a knitted fabric will be described as an example. However, the footgear 10 may be made by sewing a cloth instead of a knitted fabric. Further, as shown in fig. 6, the heat retaining portion (for example, the knee portion 2, the heel portion 4, and the fingertip portion 6) and portions other than the heat retaining portion may also be knitted with the same knitting yarn. In this case, the heat retaining sheet 9 may be attached only to the heat retaining portion, for example, to the skin side, or a storage bag portion, not shown, for storing a heat retaining material may be formed. The heat-retaining sheet 9 may be a knitted sheet or a nonwoven fabric formed of fibers having heat-retaining properties (e.g., physical properties or structures such as heat generation, heat insulation, and temperature sensation) such as fibers having heat-absorbing and heat-generating properties. The heat-retaining sheet 9 may be a sheet made of a non-fibrous material as long as it has heat-retaining properties. Fig. 6 illustrates, as an example, a case where the heat insulating sheet 9 is attached to the footgear 10 shown in fig. 3. However, it goes without saying that the heat retaining sheet 9 and the like may be attached to the footgear 10 shown in fig. 1.

In embodiments 1 and 2, a case where the sock is a foot sock is described as an example. However, the sock is not limited to the continuous knitted fabric as described above, and may be a garment that keeps warm only at the knees, heels, and fingertips. In addition, the warm portion may be provided at an ankle portion corresponding to the ankle portion in addition to the knee portion 2, the heel portion 4, and the fingertip portion 6.

(embodiment mode 3)

A further embodiment of the present disclosure will be described below with reference to fig. 7.

In embodiments 1 and 2, a case where the clothing provided by the present disclosure is socks is described as an example. However, the garment provided by the present disclosure is not limited to socks. As mentioned previously, AVA vessels are also present in the upper limb (arm). Therefore, the clothes may be sleeves (arm wear) or pajamas (night wear) covering the limbs including the upper and lower limbs.

That is, the clothing provided by the present disclosure is clothing that covers at least a portion of at least one of the upper limbs and the lower limbs. The clothing article has a plurality of heat retaining parts having higher heat retaining property than other parts, and the heat retaining parts may include at least one of the knee parts, the heel parts, the toe parts of the lower limbs, the wrist parts, the elbow parts, and the finger tip parts of the upper limbs.

Therefore, a case where the clothing provided in the present embodiment is an oversleeve (oversleeve) will be described below as an example.

Fig. 7 is an external view schematically illustrating the sleeve 100 according to the present embodiment. Fig. 7 shows a schematic external view at reference numeral 1021 when the cuff 100 according to the present embodiment is viewed from the outside of the arm, and fig. 7 shows a schematic external view at reference numeral 1022 when the cuff 100 according to the present embodiment is viewed from the inside of the arm.

The cuff 100 shown in fig. 7 is a mitten having a length from a fingertip of an upper limb to a part of an upper arm. In addition, specifically, a part of the upper arm portion refers to an upper half of the upper arm portion (i.e., an upper half of a portion between the shoulder and the elbow). The cuff 100 has an elbow upper portion 101, an elbow 102, an arm portion 103, a wrist portion 104, a hand main body portion 105, and a fingertip portion 106. A heat dissipation portion 151 having higher air permeability than the other portions is provided in a part of the hand body 105.

An insertion opening 111 is provided in the elbow upper 101, and the insertion opening 111 is provided with an opening, i.e., an insertion opening 112 for inserting an upper limb into the cuff 100. The insertion opening 112 is provided at the upper end of the cuff 100 (the end of the elbow upper portion 101 on the opposite side of the elbow 102).

On the other hand, a fingertip 106 is provided at the lower end of the cuff 100. The fingertip portion 106 is formed in a bag shape to wrap all fingertips of the hand except the thumb (in other words, 4 fingers except the thumb). The heat dissipation portion 151 is provided in a portion of the hand body portion 105 adjacent to the fingertip portion 106. The heat dissipation portion 151 is preferably formed as a mesh portion, for example, and when the heat dissipation portion 151 is a knitted fabric, it is preferably knitted by, for example, an uneven knit (mesh knitting). The heat dissipation portion 151 is woven in a mesh shape, for example, by an uneven weave method, so that air permeability can be improved, and heat at the toe portion 106 and the vicinity thereof can be effectively dissipated from the heat dissipation portion 151 to the outside. However, the heat dissipation part 151 may have any structure as long as it can improve air permeability as compared to other parts. In the present embodiment, the heat dissipation portion 151 is formed by an uneven weave, but like the heat dissipation portion 51 provided in embodiment 1, the air permeability of the heat dissipation portion 151 can be improved by increasing the size of stitches or making the thickness of knitting yarns finer, for example. Further, a mesh-like material may be sewn to the portion of the hand body portion 105 adjacent to the fingertip portion 106. The heat dissipation portion 151 includes a back portion and a palm portion, and is preferably provided in a circumferential shape (ring shape). In the example shown in fig. 7, the case where the heat dissipation portion 151 is provided circumferentially around the hand body 105 along the finger tip portion 106 is illustrated as an example. The heat dissipation portion 151 thus formed can dissipate heat efficiently. The area of the heat dissipation portion 151 is not particularly limited as long as it is within the range of the hand main body 105. However, the larger the area of the heat dissipation portion 151 is, the higher the heat dissipation effect is, and on the other hand, the cooling is easy. Therefore, the heat dissipation portion 151 is preferably provided in the hand body 105 in a range from 1/3 to 1/2 on the fingertip 106 side.

The finger tip portion 106 has a length such that it can cover at least the third joint from the tip of the hand (finger tip) to the finger tip other than the thumb (in other words, 4 fingers other than the thumb) when the cuff 100 is worn. Thus, the toe portion 106 covers the upper and lower faces of the third joint of the hand (i.e., the third joint of the fingertip) other than the thumb.

The third joint of the hand (finger tip) referred to in the present disclosure is referred to as a middle metacarpophalangeal joint or MP joint, and is formed as a joint connecting the end portion on the finger tip side of the metacarpal bones and the end portion on the wrist side of the proximal bones. The upper surface of the third joint is a skin surface corresponding to the back side of the third joint, and the lower surface of the third joint is a skin surface corresponding to the palm side of the third joint.

The elbow 102, wrist 104 and fingertip 106 are insulated sections that have a higher thermal insulation than the rest of the sections.

In addition, the elbow 102 preferably covers at least a portion of the area corresponding to the ulna. Also, the wrist portion 104 preferably covers at least a part of the area corresponding to the wrist bone. The wrist bones are the general names of scaphoid, lunate, triquetrum, bean, trapezium, trapezoid, capitate, and hamate. This can reduce cold in particular.

In the embodiment, the upper elbow 101 represents a portion covering an area above the elbow joint. The arm 103 represents a portion covering the area between the elbow joint and the wrist 104. The hand body 105 indicates a portion covering a region between the wrist portion 104 and the fingertip portion 106.

In the present embodiment, the fabric of the clothing (in the present embodiment, the cuff 100) may be a knitted fabric (knitwear) or a woven fabric. However, in order to provide the fit, and to prevent the wearer from being loosened without causing excessive tightening, the fabric of the clothing preferably has a degree of stretchability as a whole that follows at least the movement that occurs during normal sleep without stress. Therefore, the cuff 100 is preferably a knitted fabric in view of easy availability of appropriate stretchability and fitting property of stitches.

In addition, even in the present embodiment, the heat retaining portion described above may be made of any material, and may have any structure as long as it has a higher heat retaining property than the other portions. However, the heat retaining portion is preferably knitted with a knitting yarn having heat retaining properties, as in embodiments 1 and 2. As the above-described material (knitting yarn), the same material as that described in embodiment 1 (knitting yarn) can be used.

In the heat-retaining portions (the elbow 102, the wrist 104, and the finger 106), the total value of the heat-retaining values W of the materials contained in the knitting yarns for knitting the respective heat-retaining portions is preferably in the range of 12.5 to 50.0, and more preferably in the range of 25.0 to 50.0. In order to avoid excessive warmth retention in the portions other than the heat retention portion, the total value of the warmth retention values W of the materials contained in the knitting yarns for the portions other than the heat retention portion (the elbow upper portion 101, the arm portion 103, and the hand main body portion 105) in the knitted cuff 100 is preferably less than 12.5. The combination of the specific materials in the heat retaining portion and the portions other than the heat retaining portion is as exemplified in embodiment 1.

Fig. 8 is a development view of the knitted fabric of the cuff 100 shown in fig. 7.

As shown in fig. 8, the cuff 100 is knitted into a continuous tubular shape from the insertion opening 112 to the fingertip portion 106 (tip end of the fingertip portion) by, for example, a circular knitting machine, similarly to the footlet 10.

In the present embodiment, as an example, knitting stitches of the elbow upper 101, the elbow 102, the arm 103, the wrist 104, the hand body 105 excluding the heat radiating portion 151, and the fingertip portion 106 are plain stitches. The knitting structure of the heat radiating portion 151 is an uneven knitting (mesh knitting).

In addition, the stitch line GL is formed in a V-shape in the stitch-added region, i.e., the elbow 102. However, the present embodiment is not limited to this, and a Y-shaped or multi-branched seam line GL may be formed in the heat retaining portion, or a long seam line GL may be provided linearly. In the present embodiment, a yarn having high heat retaining property may be partially inserted only into a portion corresponding to the heat retaining portion.

The wrist has relatively little subcutaneous fat and muscle. Further, since the back side (outer side) of the wrist is located on the opposite side to the body, it is difficult to warm up the wrist by body temperature as compared with the palm side (inner side) which is the opposite side to the back side. In other words, the back side of the wrist is more susceptible to the outside air than the palm side, and is more likely to be cooled. Therefore, the wrist portion 104 can knit the heat retaining portion so as to cover only the back side by forming a stitch line by reciprocating rotation of the knitting machine, or knit the heat retaining portion so as to cover only the back side by a cut lace (cut boss) in which knitting yarns are switched in the middle of the circumferential direction, similarly to the heel portion 4. However, the difference in the cooling tendency due to the portion is not large in relation to the distance between the heel and the opposite side or the periphery thereof, because of the thickness of the wrist (the distance between the back side of the wrist and the opposite side thereof) and the like, between the back side of the wrist and the opposite side (the inner side) thereof. Therefore, in the case of the wrist, even if the heat retaining portion is provided in a circumferential shape, excessive heat retention is difficult. In the case of the foot, AVA exists in the sole and toes, and is particularly effective in warming the knee, the heel, and the fingertip of the foot. However, in the case of the hand, AVA exists on the palm side (inner side) and does not exist on the back side. Since the arterious vein passes directly under the skin on the inner side of the wrist, the blood flowing out due to the expansion of the AVA can be warmed by warming the inner side of the wrist, and the fingertip and the like can be warmed quickly. Therefore, in the present embodiment, in order to avoid an increase in production efficiency and cost, the wrist section 104 is formed in a flat tubular shape and the heat retaining section is knitted in a circumferential shape, without providing the split line GL, as in the arm section 103 and the hand main body section 105.

In addition, the fingertip 106 is located farthest from the heart at the site covered by the three heat retaining portions, and the blood flow tends to be slow, so that the site is also likely to feel cold. Therefore, it is preferable that the tip portion 106 has a higher heat retaining force than the other heat retaining portions. Therefore, it is preferable to design the fingertip portion 106 to have a thicker cloth than the other heat retaining portions by increasing the number of knitting yarns and the like. In order to further improve the heat retaining property, the toe portion 106 may be formed into a loop structure having a loop-like stitch and a bulky structure.

Further, the cylinder diameter (diameter of the cylinder) of the circular knitting machine is preferably larger than the cylinder diameter (3.75 to 4.0 inches) of a general cuff knitting circular knitting machine. The cylinder diameter of a circular knitting machine is the diameter of the cylinder that contributes to the completion of knitting. By making the diameter of the circular knitting machine larger than 4.0 inches, the cuff 100 can have soft and gentle tightening and stretching properties. In the present embodiment, a circular knitting machine having a cylinder diameter of 5.0 inches is used as the circular knitting machine. This makes it possible to obtain a comfortable cuff 100 that does not interfere with relaxation, and as a result, a more comfortable wearing feeling that does not interfere with sleep can be obtained.

However, the cuff 100 may be knitted by using a circular knitting machine having a cylinder diameter of 3.75 inches, for example, as long as it does not have a strong tightening force to prevent sleep. As a method of adjusting the tightening feeling when using such a normal needle cylinder, for example, a method of using an elastic yarn having low stretchability as the back layer yarn or reducing the insertion amount of the elastic yarn may be considered.

In the case where the clothing is the cuff 100, as in the case of the footlet 10, natural skin touch is emphasized as the material of the top layer yarn, and for example, natural fibers such as cotton and silk are preferably used. However, the material of the top layer yarn is not particularly limited as long as a softer hand is emphasized and a skin touch that does not disturb sleep can be obtained, and a material such as a blended yarn of cotton and modal, a blended yarn of rayon and silk, or the like can be used.

In addition, the material of the inner layer yarn is also not particularly limited. For the inner layer yarn, FTY, for example, can be used.

In the present embodiment, a 30-count single yarn woven yarn obtained by blending 50 wt% of an acrylate-based fiber and 50 wt% of polyester is used as the knitting yarn, and 30/150FTY is used as the back yarn in the heat-insulating part. In addition to the heat-insulating part, textile yarn of 10 count single yarn containing 100 wt% cotton was used for the knitting yarn, and 30/75FTY was used for the back layer yarn. Since the cuff 100 of the present embodiment uses a cylinder having a cylinder diameter of 5.0 inches, a soft and conformable property is obtained. In addition, although a knitting machine having 84 needles is used according to the number of surface layer yarns, a knitting machine having 208 needles may be appropriately selected for the surface layer yarns of 30 single yarns, for example, as in the footlet 10.

In addition, the elbow upper 101 covering the upper arm portion is particularly preferably of a loose structure. In particular, the insertion opening 111 in the elbow upper 101 is preferably designed to reduce stress caused by tightening as much as possible so as not to hinder loosening. Further, it is preferable that the upper end of the elbow 102 of the cuff 100 (specifically, the portion from the upper end of the elbow 102 to the insertion opening 112) is weaker than the tightening force of the arm 103.

Thus, for example, the inlet portion 111 is preferably woven, for example, with an embossing weave. However, as long as the tightening is gentle, the insertion opening 111 may be woven by another weaving method, for example, sinker weaving or the like.

(modification example)

In the present embodiment, as described above, the length of the cuff 100 is set to a length that at least partially covers the upper half of the upper arm. However, the length may be a length from the fingertip to the upper part of the elbow as long as the length covers the entire surface of the elbow. However, since the warmer is more likely to be felt as the area covering the upper limbs (arms) is larger, the effect of eliminating the coldness as soon as possible can be easily obtained by setting the length of the cuff 100 to a length that at least partially covers the upper half of the upper limbs.

Although not shown, the cuff 100 may be provided with a structure for pressing or stimulating the acupuncture points (acupoints) effective for improving cold.

In the present embodiment, a case where the fingertip 106 extends from the tip of the hand to the third joint of the hand other than the thumb will be described as an example. However, the toe portion 106 may be formed by bending, for example, the toe portion 106 so that the toe portion 106 covers the third joint of the hand including the thumb from the tip of the hand.

(embodiment mode 4)

A further embodiment of the present disclosure will be described below with reference to fig. 9. In addition, for convenience of description, members having the same functions as those described in embodiment 3 are denoted by the same reference numerals, and description thereof is not repeated. Note that, needless to say, this embodiment can be modified in the same manner as embodiment 3.

Fig. 9 is an external view schematically showing a main part of the cuff 100 according to the present embodiment. Fig. 9 shows a view 1031, which shows a state in which the opening portion 161 of the cuff 100 according to the present embodiment is folded so that the edge of the exposure port 162 overlaps the opening portion 161, and the exposure port 162 is closed. Fig. 9, denoted by reference numeral 1032, shows a state in which a part of the fingertip portion 106 (a part closer to the fingertip side than the exposure port 162) of the cuff 100 according to the present embodiment is rolled up to expose a part of the fingertip.

In the cuff 100, the heat radiating portion may be an opening through which the fingertips can be exposed, as in the footlet 10. Therefore, the cuff 100 may further include an opening portion as a heat radiating portion, through which the fingertips can be exposed. In the cuff 100 shown in fig. 9, instead of providing the mesh portion as the heat radiating portion 151 in the hand body portion 105, the fingertip portion 106 is provided with an opening portion 161 having an exposure opening 162 capable of exposing a fingertip as the heat radiating portion. Except for this, the cuff 100 provided in the present embodiment is the same as the cuff 100 provided in embodiment 3. In the example shown in fig. 9, the exposure port 162 is provided on the back side (upper surface side) of the fingertip portion 106.

Further, the fingertip portion 106 of the cuff 100 shown in fig. 9 covers the lower face of at least the third joint of the fingertip (finger) other than the thumb. The size of the exposure port 162 may be a size that can expose at least a part of a fingertip, but is preferably a size that can pull down the fingertip 106 to pull out the fingertip from the exposure port 162. In addition, specifically, "at least a part of a fingertip" means at least a part of a plurality of fingers. When the fingertip 106 is pulled down and the fingertip is pulled out from the exposure opening 162, it is not necessary to completely expose all 5 fingers from the exposure opening 162. However, the exposure opening 162 preferably has a size capable of protruding a part (fingertip) of all 5 fingers.

In the present embodiment, it is preferable that the opening portion 161 is provided with an exposure port 162 on the front end side (fingertip side) of the third joint of the finger other than the thumb so that the fingertip portion 106 covers at least the third joint of the hand (fingertip) other than the thumb. This can effectively expose the fingertips while maintaining a minimum heat retaining property.

The exposure port 162 is preferably formed in such a position and shape that the fingertip is not inadvertently exposed due to slight friction with bedding or the like in the initial stage of wearing of the cuff 100, in other words, from bedtime to intentional exposure of the fingertip.

As described above, even in the case where the clothing is a cuff such as the cuff 100, the exposure port 162 is provided on the back side (upper surface side) of the fingertip portion 106, so that the operation of exposing the fingertip (the operation of taking off the fingertip by hand) can be easily performed. By providing the finger tip portion 106 with the exposure port 162 in this manner, the cuff 100 can be partially detached from the finger tip portion 106, and a part of the finger tip can be exposed by protruding from the exposure port 162.

Fig. 10 is a development view of the knitted fabric of the cuff 100 shown in fig. 9.

As shown in fig. 10, the cuff 100 according to the present embodiment is knitted into a continuous tubular shape from the insertion opening 112 to the exposure opening 162 (in other words, the tip of the opening portion 161) by, for example, a circular knitting machine.

In the present embodiment, as an example, the knitted stitches of the elbow upper portion 101, the elbow 102, the arm portion 103, the wrist portion 104, the hand main body portion 105, and the fingertip portion 106 are plain stitches. However, the knitting structure of the opening portion 161 in the fingertip portion 106 is a plain structure including an elastic band. In addition, the stitch line GL is formed in a V-shape in the stitch-added region, i.e., the elbow 102.

As described in embodiment 3, in the case of the wrist, the finger tip and the like can be quickly warmed by warming the inside of the wrist. Therefore, in the present embodiment, similarly to embodiment 3, in order to avoid an increase in production efficiency and cost, the wrist section 104 is formed in a flat tubular shape without providing the split line GL, and the heat retaining section is woven in a circumferential shape, similarly to the arm section 103 and the hand main body section 105.

Further, as in embodiment 3, the cylinder diameter (diameter of the cylinder) of the circular knitting machine preferably has a diameter (3.75 to 4.0 inches) larger than that of a cylinder of a general cuff knitting circular knitting machine. By making the diameter of the circular knitting machine larger than 4.0 inches, the cuff 100 can have soft and gentle tightening and stretching properties. Therefore, in the present embodiment, a circular knitting machine having a cylinder diameter of 5.0 inches is also used as the circular knitting machine. This makes it possible to obtain a loose-fitting cuff 100 that does not interfere with relaxation, and as a result, a more comfortable wearing feeling that does not interfere with sleep can be obtained.

Further, as for the material of the surface layer yarn, as described in embodiment 3, the material of the back layer yarn is also not particularly limited. However, in the present embodiment, in order to facilitate exposure of fingertips at bedtime, it is preferable to use a yarn having lower stretchability and lower tightening force (for example, stretch nylon) than other regions as the back layer yarn in the fingertip portion 106. However, the present embodiment is not limited to this, and FTY that provides a normal tightening force may be used as the inner layer yarn in the fingertip portion 106.

In the present embodiment, as in embodiment 3, the knitting yarn in the heat-retaining portion is a 30-count single yarn woven from 50 wt% of an acrylate fiber and 50 wt% of polyester. 30/150FTY was used as the back layer yarn in the heat-retaining portion other than the fingertip portion 106. As described above, the inner layer yarn of the heat insulating portion of the toe portion 106 is made of stretch nylon. For the knitting yarns other than the insulating portion, textile yarns of 10 count single yarn of 100 wt% cotton were used, and 30/75FTY was used for the back layer yarn. Since the cuff 100 of the present embodiment uses a cylinder having a cylinder diameter of 5.0 inches, a soft and conformable property is obtained. Further, although a knitting machine with 84 needles is used depending on the number of surface layer yarns, a knitting machine with 208 needles may be appropriately selected for the surface layer yarns of 30 single yarns, for example, as in the footlet 10. However, the present embodiment is not limited to the above configuration. This embodiment may be modified in the same manner as embodiment 1.

In the present embodiment, a case where the fingertip portion 106 covers at least the third joint of a fingertip (finger) other than the thumb has been described as an example. However, the fingertip portion 106 may cover at least one of the upper surface and the lower surface of the third joint of the hand (fingertip) other than the thumb.

(modification 1)

Fig. 11 is an external view schematically showing a main part of the cuff 100 according to the present modification. Fig. 12 is a development view of the knitted fabric of the cuff 100 shown in fig. 11.

The cuff 100 shown in fig. 11 and 12 is provided with a finger tip 163 into which a thumb is inserted in the finger tip 106, and the tip (end opposite to the hand body 105) of the finger tip 106 is formed in a bag shape so as to wrap all the finger tips except the thumb. Otherwise, the sleeve 100 shown in figures 11 and 12 is identical to the sleeve 100 shown in figures 9 and 10. The position of the third joint of the finger other than the thumb is closer to the front end side (fingertip side) of the hand than the position of the third joint of the thumb. Therefore, according to the present modification, by providing the finger tip 163 into which the thumb is inserted in the finger tip 106, it is possible to easily expose a part of the finger tip (a part of the finger other than the thumb) from the exposure port 162 in a state where the third joint of each finger is covered.

In the cuff 100, the finger cuff 163 into which a thumb is inserted is provided in the cuff 100, so that the finger cuff 163 can be moved independently of the other portion of the fingertip portion 106 in a state in which the thumb is inserted into the finger cuff 163. Therefore, the movement of shifting the position of the opening 162 or pulling the bedding can be performed without exposing the thumb.

Further, by providing the cuff 100 with the finger sleeve 163 into which the thumb is inserted, the displacement of the cuff 100 due to the movement of the hand can be suppressed or prevented.

In the present modification, the stitch line GL is formed in a V-shape in the needle-added region, that is, the elbow 102, and the stitch line GL is formed in a V-shape in the finger cuff 163 of the needle-added region, that is, the fingertip portion 106, so as to wrap the thumb. However, the present modification is not limited to this, and a Y-shaped or multi-branched seam line GL may be formed in the heat retention portion, or a long seam line GL may be provided linearly. In the present modification, a yarn having high heat retaining property may be partially inserted only into a portion corresponding to the heat retaining portion.

(modification 2)

In embodiments 3 and 4, the case where the cuff 100 is a knitted fabric has been described as an example. However, the cuff 100 may be made by sewing a cloth, not a knitted fabric, as in the foot sock 10. Although not shown, the cuff 100 may be knitted with the same knitting yarn as the ankle sock 10, and the heat retaining portion (for example, the elbow 102, the wrist portion 104, and the finger tip portion 106) and portions other than the heat retaining portion. In this case, a heat insulating sheet similar to the heat insulating sheet 9 may be attached only to the heat insulating portion, for example, on the skin side, or a storage bag portion, not shown, for storing a heat insulating material may be formed.

In the present embodiment, a case where the oversleeve is an oversleeve (a long glove) is described as an example. However, the cuff is not limited to the continuous knitted fabric as described above, and may be a garment that warms only the elbow, wrist, and fingertip, as in the case of socks.
