Description

Technical Field

[0001] The present invention relates to footwear that can be worn at least on the feet, such as socks (short socks, high socks, etc.), leg warmers, stockings, tights, etc. Background Art

[0002] In the past, "socks with raised portions formed on the heels of the acupuncture points located on the soles of the feet corresponding to the vicinity of the so-called insomniac area" have been proposed (see, for example, Japanese Registered Utility Model No. 3210355). Wearing such socks can stimulate the insomniac acupuncture points, stabilize the agitated nerves, induce sleepiness, and improve poor concentration.

[0005] Patent Document 1: Japanese Registered Utility Model No. 3210355 Summary of the invention

[0006] Technical problem to be solved by the invention

[0007] In addition, the inventors of the present invention have found through in-depth research that the shape of the raised portion makes it difficult for the wearer to feel the stimulation of the insomnia acupoints.

[0008] The technical problem of the present invention is to provide a footwear that can make the wearer feel the stimulation of insomnia points more effectively than conventional footwear.

[0009] Solutions for solving technical problems

[0010] The footwear involved in the first aspect of the present invention is used to cover at least a person's foot, and has a heel covering portion and a raised portion. In addition, the footwear can cover only a part of a person's foot, or can cover the entire person's foot. In addition, a leg covering portion for covering a person's leg can also be added to the footwear. The heel covering portion is a portion for covering a part or all of the heel. There is at least one raised portion. The raised portion is raised toward at least one of the inner side and the outer side in the heel covering portion. And the raised portion has an angle. In addition, the "angle" mentioned here includes not only the angle formed by the intersection of straight lines, but also the angle formed by the combination of straight lines and curves (circular arcs, etc.), i.e., rounded corners. However, from the perspective of effectively stimulating insomnia acupuncture points, it is preferred that the radius of the rounded corner is less than 15 mm. The lower limit of the radius of the rounded corner is not specifically specified, but is, for example, 0.1 mm. In addition, when the wearer exercises such as walking, the wearer's own weight acts on the raised portion, and the area where the wearer's own weight acts becomes smaller, so the pressure applied to the insomnia acupuncture points increases.

[0011] As described above, in the footwear, a corner is formed in the raised portion. Compared with a raised portion formed by a gentle curve or curved surface, the wearer of the footwear can more easily feel the contact with the raised portion having a corner. Therefore, by wearing the footwear before going to bed or by the wearer walking gently before going to bed, the wearer can more effectively feel the stimulation of the insomnia acupuncture points than in the previous footwear. In addition, in the case where the raised portion is raised toward the outside of the heel cover, in order to stimulate the insomnia acupuncture points through the raised portion, at least a light exercise such as walking is required.

[0012] A foot wearing device according to a second aspect of the present invention is the foot wearing device according to the first aspect, wherein the raised portion has a polygonal shape.

[0013] Therefore, a plurality of corners are formed in the footwear. Therefore, the footwear can make the wearer feel the stimulation of the acupuncture points for insomnia more effectively than the conventional footwear.

[0014] The footwear according to the third aspect of the present invention is the footwear according to the second aspect, wherein the raised portion is in a cross shape when viewed from above. In addition, "viewed from above" means viewing the footwear from directly above when the heel covering portion is placed flatly toward the bottom.

[0015] Therefore, in the footwear, two relatively sharp corners are formed on each of the four sides of one raised portion. Therefore, in the footwear, the insomnia acupuncture point can be stimulated at the positions of the four sides, and even if the position of the raised portion is slightly offset from the insomnia acupuncture point when the footwear is worn, the insomnia acupuncture point can still be stimulated.

[0016] The footwear involved in the fourth aspect of the present invention is the footwear involved in the third aspect, and the raised portion has a rectangular portion, a first wing portion, and a second wing portion. The rectangular portion is rectangular when viewed from above. The first wing portion extends from the rectangular portion toward both sides along the width direction. The second wing portion extends from the rectangular portion toward both sides in a direction perpendicular to the width direction when viewed from above. In addition, the upper end face of the rectangular portion is located at a position higher than the upper end face of the first wing portion and the upper end face of the second wing portion. In other words, the rectangular portion is thicker than the first wing portion and the second wing portion.

[0017] Therefore, in the footwear, a corner can also be formed in the central rectangular portion. Therefore, the central portion of the insomnia point can be effectively stimulated in a state where the footwear is normally worn.

[0018] A footwear according to a fifth aspect of the present invention is the footwear according to any one of the first to fourth aspects, wherein the heel cover portion is formed by an inner knitted layer and an outer knitted layer, and the raised portion is located between the inner knitted layer and the outer knitted layer.

[0019] Therefore, in the footwear, it is possible to suppress the raised portion from being worn or deteriorated.

[0020] The footwear according to the sixth aspect of the present invention is the footwear according to the fifth aspect, wherein the raised portion is composed of a first protrusion and a second protrusion. The first protrusion protrudes from the inner knitted layer toward the outer knitted layer. The second protrusion protrudes from the outer knitted layer toward the inner knitted layer. The second protrusion is arranged to face the first protrusion.

[0021] Therefore, in the footwear, a sufficiently high raised portion can be formed using a relatively simple knitting structure.

[0022] A footwear according to a seventh aspect of the present invention is the footwear according to the first aspect, and is used to promote falling asleep.

[0023] Therefore, the person wearing the footwear can easily fall asleep.

[0024] A footwear according to claim 8 of the present invention is the footwear according to claim 7, and is in the shape of a tube with both sides opened.

[0025] Therefore, in the footwear, the vascular area (for example, the AVA vascular area, etc.) on the toe side of the wearer's foot can be exposed. Therefore, in the footwear, the deep body temperature of the wearer can be sufficiently lowered, and the wearer can be provided with high-quality sleep. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] <Configuration of footwear according to embodiments of the present invention>

[0035] The footwear according to the embodiment of the present invention is a piece of clothing worn on a person's foot, such as socks (foot covers, short socks, high socks), leg warmers, stockings, tights, etc. In addition, the "foot" mentioned here refers to the area from the ankle to the toe. In addition, the footwear may cover only a part of a person's foot or the entire foot. In addition, the footwear may also include a leg covering portion for covering a person's leg, such as short socks, high socks, leg warmers, stockings, tights, etc.

[0036] As an example of the footwear according to the embodiment of the present invention, there can be cited: Figure 1 The sleeping promotion leg warmer socks 100 shown. In addition, the sleeping promotion leg warmer socks 100 are invented to realize the three concepts shown in the following a), b) and c).

[0037] a) By warming the feet except the toes, the inconvenience of being unable to fall asleep due to cold feet can be suppressed.

[0038] b) The toes are opened to lower the wearer’s deep body temperature and induce sleepiness.

[0039] c) By stimulating the insomnia point located on the heel, it acts on the parasympathetic nerves to relax the wearer's body.

[0040] Hereinafter, the sleeping promoting leg warming socks 100 will be described in detail, and the configurations that are permissible in the present invention will be explained.

[0041] The sleeping promotion leg warmer socks 100 according to the embodiment of the present invention are a tubular knitted fabric with openings at both ends and a shape of a "く" character. Figure 1As shown, it is mainly composed of a partial foot covering portion 110, a first pressing portion 120, a connecting portion 130, an ankle covering portion 140, a second pressing portion 150 and a calf covering portion 160. These components are described in detail below.

[0042] (1) Partial foot covering

[0043] The partial foot covering portion 110 is a tubular portion having a double-layer knitted structure, and is used to cover the middle portion of the wearer's foot, that is, for example, an area corresponding to about 50% of the foot length (the distance from the heel side end of the foot to the end of the longest toe). As described above, the partial foot covering portion 110 has a double-layer knitted structure, so it has a heat-insulating function through the air layer located between the layers. In addition, as Figure 1 and Figure 2As shown, one end of the partial foot covering portion 110 is the front end of the sleep-promoting leg warming socks 100, and the other end is connected to the first pressing portion 120. That is, if the sleep-promoting leg warming socks 100 are worn, the toe side of the wearer's foot is exposed. The size of the partial foot covering portion 110 is designed for people with an average foot shape and a foot length in the range of 22 cm to 25 cm. In addition, in order to a) not cover the blood vessels of the foot (for example, the AVA blood vessels are concentrated), promote the wearer's deep body temperature to fall and guide sleep, and b) by covering the parts other than the blood vessels, slow down the temperature drop rate of the foot to prevent sleep disorders caused by cold feet, the length of the partial foot covering portion 110 is set to not exceed the length of the root of the little toe or the fifth metatarsal bone of a person with an average foot shape and a foot length of 22 cm. In this case, when the sleeping promotion leg warmers 100 are worn, the partial foot covering portion 110 covers the portion from the heel side to the range of 63.3% to 83.1% of the foot length. From the viewpoint of slowly tightening to prevent discomfort, the partial foot covering portion 110 is preferably woven using a pure fabric without using a base yarn (FTY). In addition, based on the same viewpoint, it is preferred that a rubber thread is inserted into the pure fabric. In addition, based on the same viewpoint, it is preferred that the elongation in the barrel axis direction of the knitted fabric is in the range of 140% to 160%, and the elongation in the width direction is in the range of 270% to 290%. In addition, the circumference of the partial foot covering portion 110 is determined in almost the same manner as the foot circumference of a person having an average foot shape and a foot length of 23.5 cm. In addition, the sleep-promoting leg warmers 100 are woven using a loom with a needle cylinder (cylinder) diameter of about 5 inches, so the circumference of the local foot covering portion 110 is longer than that of a loom with a diameter of about 3.5 inches, and the tightening of the middle part of the foot is reduced. In addition, it is preferred that the wearing pressure of the local foot covering portion 110 is within the range of 9.50±0.49 hPa, and more preferably within the range of 9.50±0.16 hPa. In addition, the wearing pressure was measured using PRESSURE CONVERTER AMI3037-10, a round air bag, and an average foot shape of HQL adult women (average human body size prosthesis MSX-20 made by a human body model of Seven Colors Co., Ltd.) at room temperature of 20°C and relative humidity of 65%. Specifically, a round air bag is attached to the average foot of HQL adult women, and the sleeping promotion leg warmer 100 is worn on the foot for one minute, and the wearing pressure measurement value displayed on the PRESSURE CONVERTER AMI3037-10 is read. Here, the measurement is performed three times and the average value is used as the wearing pressure. In this way, not only a firm fabric feeling can be obtained, but also longitudinal expansion and contraction can be suppressed to prevent the displacement of the wearing position.In addition, the partial foot covering portion 110 does not over-tighten the middle part of the wearer's foot and fits the middle part of the foot, which can provide comfort to the wearer. In addition, the sleeping promotion leg warmer socks 100 can suppress positional deviation by having the above-mentioned structure.

[0044] (2) First clamping part

[0045] The first pressing part 120 is a tubular part with a double-layer knitted structure, which is used to cover the toe side of the wearer's heel and prevent the partial foot covering part 110 and the ankle covering part 140 from shifting (slipping, rolling up, etc.) when the sleep-promoting leg warmer 100 is worn. As described above, the first pressing part 120 has a double-layer knitted structure, so it has a heat-insulating function through the air layer located between the layers. In addition, Figure 1 and Figure 2 As shown, one end of the first pressing part 120 is connected to the partial foot covering part 110, and the other end is connected to the connecting part 130. In addition, from the viewpoint of suppressing positional deviation as described above, it is preferred that the knitted fabric for knitting the first pressing part 120 is a knitted fabric with stronger fastening than the knitted fabric for knitting the partial foot covering part 110 and the ankle covering part 140. Therefore, it is preferred that the first pressing part 120 is knitted using plain knitting using a ground yarn (FTY). In addition, based on the same viewpoint, it is preferred that a rubber thread or a pattern yarn is inserted into the plain knitting. In addition, based on the same viewpoint, it is preferred that the elongation in the barrel axis direction of the knitted fabric is within a range of 240% to 260%, and the elongation in the width direction is within a range of 190% to 210%. In addition, it is preferred that the wearing pressure of the first pressing part 120 is within a range of 33.20±3.56hPa, and more preferably within a range of 33.20±1.19hPa. As a result, the partial foot covering portion 110 and the ankle covering portion 140 are less likely to be misaligned, and the functions of the partial foot covering portion 110 and the ankle covering portion 140 can be fully exerted.

[0046] In addition, if Figure 1 and Figure 2 As shown, a cross-shaped protrusion 125 is formed at a position corresponding to the insomnia acupuncture point on the sole covering side of the first pressing part 120. In addition, as mentioned above, the first pressing part 120 has a double-layer knitted structure, such as Figure 3 As shown in FIG. 1 , the double-layer knitted structure is composed of an inner knitted layer 120a and an outer knitted layer 120b. Figure 3 As shown, the protrusion 125 is composed of a first protrusion 125a protruding from the inner knitted layer 120a toward the outer knitted layer side and a second protrusion 125b protruding from the outer knitted layer 120b toward the inner knitted layer side. Figure 3 As shown in FIG. 1 , the first protrusion 125a and the second protrusion 125b are arranged opposite to each other. Figure 3 and Figure 4 As shown in FIG. 1 , the first protrusion 125a and the second protrusion 125b are composed of a rectangular portion RG, a first wing portion W1, and a second wing portion W2. The rectangular portion RG is a rectangular parallelepiped portion made of knitted fabric. Figure 3 As shown, the design is such that the lower end surface of the rectangular portion RG in the first protrusion 125a is located lower than the lower end surface of the first wing W1 and the lower end surface of the second wing W2, and the upper end surface of the rectangular portion RG in the second protrusion 125b is located higher than the upper end surface of the first wing W1 and the upper end surface of the second wing W2. In other words, the design is such that the rectangular portion RG in the first protrusion 125a and the second protrusion 125b is thicker than the first wing W1 and the second wing W2. Figure 4 As shown in FIG. 1 , the first wing portion W1 is a rectangular parallelepiped portion extending from the rectangular portion RG along the width direction Dw to both sides of the rectangular portion RG. Figure 3 As shown, in the first protrusion 125a and the second protrusion 125b, the lower end surface or the upper end surface of the first wing W1 is located at the same height position as the lower end surface or the upper end surface of the second wing W2. In addition, as described above, it is designed in such a way that in the first protrusion 125a, the lower end surface of the first wing W1 is located at a higher position than the lower end surface of the rectangular portion RG, and in the second protrusion 125b, the upper end surface of the first wing W1 is located at a lower position than the upper end surface of the rectangular portion RG. In other words, it is designed in such a way that in the first protrusion 125a and the second protrusion 125b, the first wing W1 is thinner than the rectangular portion RG. Figure 4 As shown, the second wing portion W2 is a rectangular parallelepiped portion extending from the rectangular portion RG to both sides of the rectangular portion RG along a direction D1 orthogonal to the width direction Dw, that is, a depth direction (a direction passing through the heel and the toe). Figure 3 As shown, the lower end face or upper end face of the second wing W2 in the first protrusion 125a and the second protrusion 125b is located at the same height position as the lower end face or upper end face of the second wing W2. In addition, as described above, it is designed in a manner that the lower end face of the first wing W1 in the first protrusion 125a is located at a position higher than the lower end face of the rectangular portion RG, and the upper end face of the first wing W1 in the second protrusion 125b is located at a position lower than the upper end face of the rectangular portion RG. In other words, it is designed in a manner that the second wing W2 is thinner than the rectangular portion RG in the first protrusion 125a and the second protrusion 125b. By forming the first protrusion 125a and the second protrusion 125b as described above, twelve corners CN are formed in the first protrusion 125a and the second protrusion 125b, respectively. In addition, four of the corners CN are formed by the rectangular portion RG, and eight of the corners CN are formed by the first wing W1 and the second wing W2.

[0047] Furthermore, by forming the raised portion 125 as described above, when the wearer wears the device and walks, the raised portion 125 formed by the first protrusion 125a and the second protrusion 125b raises toward the inside (skin side) (at this time, the upper end surface of the rectangular portion formed by the rectangular portion RG of the first protrusion 125a and the rectangular portion RG of the second protrusion 125b is located at a higher position than the upper end surface of the first wing formed by the first wing W1 of the first protrusion 125a and the first wing W1 of the second protrusion 125b, and the upper end surface of the second wing formed by the second wing W2 of the first protrusion 125a and the second wing W2 of the second protrusion 125b), and twelve corners are formed at positions corresponding to the corners CN of the first protrusion 125a and the second protrusion 125b in the raised portion, and the insomnia acupuncture points can be efficiently stimulated through these corners.

[0048] Furthermore, when the protrusions 125a and 125b are formed by knitted fabric, it is preferable to form the protrusions 125a and 125b in the following manner. Specifically, the protrusions 125a and 125b are knitted by knitting methods such as terry knitting or by combining variations of yarns such as thick yarns. In this way, the first protrusion 125a can be integrated with the inner knitted layer 120a, and the second protrusion 125b can be integrated with the outer knitted layer 120b, without increasing the steps for forming the protrusions 125a and 125b, and the positional deviation of the protrusions 125a and 125b due to poor bonding can be suppressed.

[0049] exist Figure 5 A more specific weaving method is shown in FIG. Figure 5 The area indicated by the 0 mark and the △ mark (hereinafter sometimes referred to as the "first area") is a plain knitting area, which is knitted using the face yarn, the base yarn and the rubber thread. The rubber thread is inserted into the portion indicated by the △ mark.

[0050] The area indicated by row numbers 3 to 11 / column numbers 1 to 4 (hereinafter sometimes referred to as the "21st area"), the area indicated by row numbers 12 to 22 / column numbers 5 to 8 (hereinafter sometimes referred to as the "22nd area"), the area indicated by row numbers 23 to 31 / column numbers 1 to 4 (hereinafter sometimes referred to as the "23rd area"), the area indicated by row numbers 3 to 11 / column numbers 129 to 132 (hereinafter sometimes referred to as the "24th area"), the area indicated by row numbers 12 to 22 / column numbers 125 to 128 (hereinafter sometimes referred to as the "25th area"), and the area indicated by row numbers 23 to 31 / column numbers 129 to 132 (hereinafter sometimes referred to as the "26th area") are knitted using face yarn, base yarn, rubber yarn, and pseudo pile yarn. In addition, in these areas, pseudo pile yarn is knitted in the gray area, but pseudo pile yarn is not knitted in the black area. By not knitting the pseudo pile yarn in the black area, the fabric in these areas becomes plush, thereby generating thickness. In addition, since there is no braided rubber thread in these areas, the rubber thread is placed horizontally on these areas. By not braiding the rubber thread like this, the rubber thread will not be flattened, and a corresponding amount of thickness is generated in this position.

[0051] The area indicated by row numbers 12 to 22 / column numbers 1 to 4 (hereinafter sometimes referred to as the "31st area") and the area indicated by row numbers 12 to 22 / column numbers 129 to 132 (hereinafter sometimes referred to as the "32nd area") are woven with face yarn, bottom yarn, rubber thread, and simulated pile yarn. In addition, in these areas, simulated pile yarn is woven in the light gray part, but simulated pile yarn is not woven in the dark gray part. This is the same as the above-mentioned areas 21 to 26, but in these areas, the plain knitting is further changed to terry knitting. As a result, these areas are thicker than the areas 21 to 26. That is, the relationship between the thickness of the above-mentioned areas is as follows.

[0052] The 31st area = the 32nd area > the 21st area = the 22nd area = the 23rd area = the 24th area = the 25th area = the 26th area > the 1st area.

[0053] In addition, similar to the 21st to 26th regions, the rubber cord is not braided in the 31st and 32nd regions, so the rubber cord is placed horizontally on these regions. By not braiding the rubber cord like this, the rubber cord is not flattened, and a corresponding amount of thickness is generated in this portion.

[0054] (3) Connection

[0055] The connecting portion 130 is an annular portion having a single-layer knitted structure, and serves to connect the first pressing portion 120 with the ankle covering portion 140. From the perspective of not interfering with the sleep of the wearer, it is preferred that the connecting portion 130 has no step difference and does not make the wearer feel tight. In addition, specific examples of the connecting portion 130 include, for example, a heat-welded portion, a sewn portion, and the like. In addition, it is preferred that the connecting portion 130 is located closer to the toes side than the heel of the wearer when the sleep-promoting leg warmers 100 are worn. From the perspective of not causing discomfort to the wearer, it is preferred that the connecting portion 130 is located at an insensitive position of the wearer's foot when the sleep-promoting leg warmers 100 are worn.

[0056] (4) Ankle cover

[0057] The ankle covering portion 140 is a tubular portion having a single-layer knitted structure and is used to cover the ankle and a portion of the heel of the wearer. Figure 1 and Figure 2 As shown, the ankle covering portion 140 is connected to the first pressing portion 120 via the connecting portion 130, and is connected to the second pressing portion 150 on the opposite side. In addition, from the viewpoint of imparting appropriate heat retention, the ankle covering portion 140 is preferably woven by terry knitting or the like. In addition, from the viewpoint of positioning the raised portion 125 of the first pressing portion 120, the ankle covering portion 140 is preferably bent in a manner along the shape of the ankle and heel during sleep. The ankle covering portion 140 is preferably provided with a reduced stitch area between the full circumference knitting areas of the ankle covering portion 140, and an increased stitch area may also be provided following the reduced stitch area. In addition, the wearing pressure of the ankle covering portion 140 is preferably within a range of 8.17±2.62 hPa or less, and more preferably within a range of 8.17±0.87 hPa or less.

[0058] (5) Second clamping part

[0059] The second pressing portion 150 is a tubular portion having a single layer of knitting, and is used to cover the portion located above the wearer's ankle, and is a portion that prevents the ankle covering portion 140 and the calf covering portion 160 from being displaced (slipping, rolling up, etc.) when the sleep-promoting leg warmer 100 is worn. Figure 1 and Figure 2 As shown, one end of the second compression part 150 is connected to the ankle covering part 140, and the other end is connected to the calf covering part 160. In addition, the wearing pressure of the second compression part 150 is preferably within the range of 5.63±0.51 hPa or less, and more preferably within the range of 5.63±0.17 hPa or less.

[0060] In addition, if Figure 1 and Figure 2As shown, an acupoint stimulating portion 155 is formed at a position on the side surface of the second pressing portion 150 corresponding to the Sanyinjiao acupoint.

[0061] (6) Calf covering

[0062] The calf covering portion 160 is a tubular portion having a double-layer knitted structure and is used to cover the wearer's calf. As described above, the calf covering portion 160 has a double-layer knitted structure, so it has a heat-insulating function through the air layer located between the layers. Figure 1 and Figure 2 As shown, one end of the calf covering portion 160 is connected to the second pressing portion 150, and the other end is the base end of the sleep-promoting leg warmer 100. In addition, from the perspective of suppressing the positional deviation (slipping, rolling up, etc.) of the calf covering portion 160 when wearing the sleep-promoting leg warmer 100, the wearing pressure of the calf covering portion 160 is preferably within the range of 4.80±3.13 hPa or less, and more preferably within the range of 4.80±1.04 hPa or less.

[0063] <Wearing pressure ratio of each part>

[0064] As described above, the preferred wearing pressure of each part is specified, but the preferred ratio thereof, i.e., the wearing pressure of the calf covering portion 160: the wearing pressure of the ankle covering portion 140: the wearing pressure of the local foot covering portion 110: the wearing pressure of the second compression portion 150: the wearing pressure of the first compression portion 120 is 4.80±3.13hPa: 8.17±2.62hPa: 9.50±0.49hPa: 5.63±0.51hPa: 33.20±3.56hPa, and more preferably 4.80±1.04hPa: 8.17±0.87hPa: 9.50±0.16hPa: 5.63±0.17hPa: 33.20±1.19hPa. That is, it is preferred that the wearing pressure of the first clamping part 120 is higher than the wearing pressure of the local foot covering part 110, the wearing pressure of the first clamping part 120 is higher than the wearing pressure of the ankle covering part 140, the wearing pressure of the ankle covering part 140 is higher than the wearing pressure of the second clamping part 150, and the wearing pressure of the second clamping part 150 is higher than the wearing pressure of the calf covering part 160.

[0069] <Features of the sleep-promoting leg-warming socks according to the embodiment of the present invention> (1)

[0071] The first compression part 120 of the sleep-promoting leg warmer 100 according to the embodiment of the present invention is provided with a raised part 125 at a position corresponding to the insomnia acupuncture point, and a corner is formed at the raised part 125. Therefore, by wearing the socks before going to bed or by the wearer walking gently before going to bed, the sleep-promoting leg warmer 100 can make the wearer feel the insomnia acupuncture point being stimulated more effectively than before. (2)

[0073] In the sleep-promoting leg warmer socks 100 according to the embodiment of the present invention, the ridge 125 is formed by a first protrusion 125a protruding from the inner knitted layer 120a toward the outer knitted layer side and a second protrusion 125b protruding from the outer knitted layer 120b toward the inner knitted layer side. Therefore, in the sleep-promoting leg warmer socks 100, even if the yarn is exposed when knitting the protrusions 125a and 125b, it is possible to prevent the yarn from being exposed to the skin side and the ground contact side. Therefore, in the sleep-promoting leg warmer socks 100, it is possible to prevent the yarn of the knitted protrusions 125a and 125b from being caught on the wearer's nails, fingers, or floor, etc. Therefore, in the sleep-promoting leg warmer socks 100, it is easy to wear and the yarn is not easy to loosen. (3)

[0075] In the sleep-promoting leg warmer socks 100 involved in the embodiment of the present invention, the wearing pressure of the calf covering part 160: the wearing pressure of the ankle covering part 140: the wearing pressure of the partial foot covering part 110: the wearing pressure of the second pressing part 150: the wearing pressure of the first pressing part 120 is set to 4.80±3.13hPa: 8.17±2.62hPa: 9.50±0.49hPa: 5.63±0.51hPa: 33.20±3.56hPa. After in-depth research, the inventors of the present application clearly found that the sleep-promoting leg warmer socks 100 with such a wearing pressure ratio will not compress the wearer's feet, ankles, upper parts of the ankles and calves to the extent of discomfort, and are not easy to fall off from the feet, ankles, upper parts of the ankles and calves during the process of falling asleep and going to bed. Therefore, the sleep-promoting leg warmers 100 are not easy to fall off from the feet, ankles, upper parts of the ankles and calves during the process of falling asleep and going to bed, and can provide the wearer with a comfortable way of falling asleep and sleeping. (4)

[0077] In the sleeping promotion leg warmer 100 according to the embodiment of the present invention, there is no wearing pressure area stronger than the partial foot covering part 110 on the side opposite to the first pressing part of the partial foot covering part 110. In conventional foot wearing devices, a wearing pressure area stronger than the part corresponding to the partial foot covering part is often provided on the front end side of the part corresponding to the partial foot covering part to prevent displacement during wearing.

[0078] <Modification>

[0079] (A)

[0080] The sleep-promoting leg warmers 100 according to the above embodiment are designed with the size of the wearer having a foot length of 22 cm to 25 cm, but the size range may be designed in units of 1 cm, for example. That is, for example, three sizes of sleep-promoting leg warmers 100 are designed for the wearer having a foot length of 22 cm to 23 cm, the wearer having a foot length of 23 cm to 24 cm, and the wearer having a foot length of 24 cm to 25 cm.

[0082] In the sleep-promoting leg warmers 100 according to the above embodiment, the length of the partial foot covering portion 110 is set to a length not exceeding the length of the base of the little toe of a person with an average foot shape and a foot length in the range of 22 cm to 25 cm, but may be set to a length covering the tip of the little toe of a person with an average foot shape and a foot length of 22 cm. In addition, in this case, if a person with an average foot shape and a foot length of 25 cm wears the sleep-promoting leg warmers 100, the portion covering the base of the little toe of the wearer is covered.

[0083] (C)

[0084] In the sleep-promoting leg warmers 100 of the above-mentioned embodiment, the partial foot covering portion 110 is designed to cover the entire circumference of the heel side of the wearer's foot, but the sleep-promoting leg warmers 100 may be designed to cover at least a portion of the lateral longitudinal arch, or may be designed to cover at least the entire lateral longitudinal arch.

[0085] (D)

[0086] In the sleeping promotion leg warmer socks 100 according to the above embodiment, the first pressing part 120 is provided between the partial foot covering part 110 and the connecting part 130 to suppress the positional deviation of the partial foot covering part 110 and the ankle covering part 140. However, the first pressing part may be provided at the toe side of the partial foot covering part 110 to suppress only the positional deviation of the partial foot covering part 110, and the first pressing part may be provided inside the ankle covering part 140 to suppress only the positional deviation of the ankle covering part 140. In the former case, it is preferable to have the same knitting structure as that of a general single-layer knitted open-toe short socks, and in the latter case, it is preferable to have the same knitting structure as that of the bag-shaped part of the double welt disclosed in the specification of Japanese Patent No. 6195139.

[0087] (E)

[0088] In the sleeping promotion leg warmer socks 100 involved in the above embodiment, the partial foot covering part 110, the first pressing part 120, and the calf covering part 160 are double-layer knitted structures, but these parts 110, 120, 160 can also be single-layer knitted structures. In this case, it is preferred that the partial foot covering part 110 is knitted into a knitted fabric with high heat retention such as terry knitting, or knitted with a yarn with high heat retention such as acrylic yarn and wool, or knitted with a moisture-absorbing and heat-generating yarn such as eks (registered trademark).
