Description

[Technical field]

[0001] The present invention relates to foot wear items that can be worn at least on the feet, such as socks (socks, knee-high socks, etc.), leg warmers, stockings, tights, etc. [Background technology]

[0002] In the past, "socks with raised areas on the heel pouch at locations on the soles of the feet that correspond to acupressure points associated with insomnia" have been proposed (see, for example, Registered Utility Model Publication No. 3210355). It is said that wearing these socks stimulates the acupressure points associated with insomnia, calming excited nerves and inducing drowsiness, improving poor concentration, etc. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Registered Utility Model No. 3210355 Summary of the Invention [Problem to be solved by the invention]

[0004] However, through careful investigation by the inventors, it has been discovered that depending on the shape of the protuberance, it may be difficult for the wearer to perceive that the acupressure point for insomnia is being stimulated.

[0005] An object of the present invention is to provide a foot attachment that allows the wearer to more effectively sense that the acupressure points causing insomnia are being stimulated, as compared to conventional foot attachments. [Means for solving the problem]

[0006] The foot attachment according to the first aspect of the present invention is an attachment for covering at least a human foot, and includes a heel covering portion and a protuberance. The foot attachment may cover only a part of the human foot, or may cover the whole of the human foot. The foot attachment may further include a leg covering portion for covering the human leg. The heel covering portion is a portion for covering a part or the whole of the heel. At least one protuberance is present. The protuberance protuberance is protuberant toward at least one of the inner and outer sides of the heel covering portion. The protuberance has a corner. The "corner" referred to here includes not only a corner formed by the intersection of straight lines, but also a corner formed by a combination of a straight line and a curved line (such as a circular arc), i.e., a rounded corner. However, from the viewpoint of effectively stimulating acupressure points for insomnia, the radius of the rounded corner is preferably 15 mm or less. The lower limit of the radius of the rounded corner is not particularly specified, but is, for example, 0.1 mm. In addition, when the wearer's own weight is applied to this protuberance while exercising, such as walking, the presence of the corners reduces the area on which the weight is applied, and the pressure applied to the acupressure point for insomnia increases.

[0007] As described above, in this foot attachment, the raised portion is formed with a corner. The wearer of the foot attachment is more likely to feel contact with an object having a corner than with an object formed with a gentle curve or curved surface. Therefore, this foot attachment can make the wearer feel that the acupressure point for insomnia is being stimulated more effectively than with conventional foot attachments by wearing it before going to bed or by the wearer walking lightly before going to bed. In addition, when the raised portion is raised toward the outside of the heel covering portion, at least light exercise such as walking is required to stimulate the acupressure point for insomnia with the raised portion.

[0008] 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.

[0009] For this reason, the foot attachment has multiple corners, so that the foot attachment can more effectively make the wearer feel that the acupressure points that cause insomnia are being stimulated than with conventional foot attachments.

[0010] A foot wearing device according to a third aspect of the present invention is the foot wearing device according to the second aspect, and the raised portion has a cross shape in a planar perspective. Note that the "planar perspective" refers to a perspective view from directly above when the foot wearing device is laid flat with the heel covering portion facing downward.

[0011] Therefore, in this foot attachment, two relatively sharp corners are formed on each of the four sides of one raised portion, so that with this foot attachment, the acupressure point for insomnia can be stimulated on all four sides, and even if the raised portion is slightly out of position from the acupressure point when the foot attachment is attached, the acupressure point for insomnia can still be stimulated.

[0012] A foot wearing device according to a fourth aspect of the present invention is the foot wearing device according to the third aspect, and the raised portion has a rectangular portion, a first wing portion, and a second wing portion. The rectangular portion has a rectangular shape in a planar perspective. The first wing portion extends on both sides from the rectangular portion along the width direction. The second wing portion extends on both sides from the rectangular portion along a direction perpendicular to the width direction in a planar perspective. The upper end surface of the rectangular portion is located higher than the upper end surfaces of the first wing portion and the second wing portion. In other words, the rectangular portion is thicker than the first wing portion and the second wing portion.

[0013] Therefore, in this foot attachment, the rectangular part in the center can also have a corner, so that the center of the acupressure point for insomnia can be effectively stimulated when the foot attachment is properly attached.

[0014] A foot wearing device according to a fifth aspect of the present invention is the foot wearing device according to any one of the first to fourth aspects, in which the heel covering part is formed of an inner knitted fabric layer and an outer knitted fabric layer, and the raised part is located between the inner knitted fabric layer and the outer knitted fabric layer.

[0015] Therefore, with this foot attachment, wear and deterioration of the raised portion can be suppressed.

[0016] A foot wearing device according to a sixth aspect of the present invention is the foot wearing device according to the fifth aspect, and the raised portion is composed of a first protrusion and a second protrusion. The first protrusion protrudes from the inner knitted fabric layer toward the outer knitted fabric layer. The second protrusion protrudes from the outer knitted fabric layer toward the inner knitted fabric layer. The second protrusion is disposed so as to face the first protrusion.

[0017] Therefore, in this foot wearing device, a raised portion of sufficient height can be formed using a relatively simple knitting structure.

[0018] A foot attachment according to a seventh aspect of the present invention is the foot attachment according to the first aspect, and is used to promote sleep.

[0019] This makes it easier for a person wearing the footwear to fall asleep.

[0020] A foot wearing device according to an eighth aspect of the present invention is the foot wearing device according to the seventh aspect, and this foot wearing device has a cylindrical shape with openings on both sides.

[0021] Therefore, this foot attachment can expose the blood vessel area (for example, AVA blood vessel area) on the toe side of the wearer's foot, and therefore can sufficiently lower the core body temperature of the wearer, thereby providing the wearer with a good quality sleep.

[0024] <Configuration of the foot attachment according to the embodiment of the present invention> The foot attachment according to the embodiment of the present invention is an attachment to be attached to a human foot, such as socks (foot covers, socks, knee-high socks), leg warmers, stockings, tights, etc. The "foot" here refers to the part from the ankle to the toes. The foot attachment may cover only a part of the human foot, or may cover the entire human foot. The foot attachment may also have a leg covering part for covering the human leg, such as socks, knee-high socks, leg warmers, stockings, tights, etc.

[0025] An example of a foot attachment according to an embodiment of the present invention is a sleep-promoting leg warmer 100 shown in Fig. 1. This sleep-promoting leg warmer 100 was invented to realize the following three concepts a), b), and c). a) By warming the feet, except for the toes, it prevents the inconvenience of not being able to sleep due to cold feet. b) The toe side is opened, lowering the wearer's core body temperature and inducing drowsiness. c) By stimulating the acupressure point located on the heel, it activates the parasympathetic nervous system and relaxes the wearer's body.

[0026] The sleep-promoting leg warmer 100 will now be described in detail, along with an explanation of configurations that may be adopted in the present invention.

[0027] The sleep-promoting leg warmers 100 according to the embodiment of the present invention are knitted fabrics in a generally V-shaped tube with both ends open, and as shown in Fig. 1, are mainly composed of a partial foot covering section 110, a first clamping section 120, a connection section 130, an ankle covering section 140, a second clamping section 150, and a shin covering section 160. These constituent parts will be described in detail below.

[0028] (1) Partial foot covering The partial foot covering part 110 is a tubular part having a double knit structure, and is a part for covering the middle part of the wearer's foot, that is, for example, an area equivalent 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 part 110 has a double knit structure, and therefore has a heat retention function due to an air layer existing between the layers. As shown in Figs. 1 and 2, one end of the partial foot covering part 110 is the tip of the sleep-promoting leg warmer 100, and the other end is connected to the first clamping part 120. That is, when the sleep-promoting leg warmer 100 is worn, the toe side part of the wearer's foot is exposed. The partial foot covering part 110 is designed in dimensions for a person having an average foot shape and a foot length within the range of 22 cm to 25 cm. In addition, the length of the partial foot covering part 110 is set not to exceed the base of the little toe or the head of the fifth metatarsal bone for a person with an average foot shape and a foot length of 22 cm, in order to a) promote a drop in the wearer's core body temperature and induce sleep without covering the areas where blood vessels are concentrated (for example, areas where AVA blood vessels are concentrated), and b) prevent sleep disturbance due to cold feet by slowing down the rate of temperature drop of the foot by covering areas other than the areas where blood vessels are concentrated. In this case, when the sleep-promoting leg warmer 100 is worn, the partial foot covering part 110 covers a part ranging from 63.3% to 83.1% of the foot length from the heel side. From the viewpoint of gently tightening the partial foot covering part 110 so as not to cause discomfort, it is preferable that the partial foot covering part 110 is knitted with a zokki knitting method that does not use a back yarn (FTY). From the same viewpoint, it is preferable that a rubber yarn is inserted into the zokki knitting. From the same viewpoint, it is preferable that the stretchability in the axial direction of the knitted fabric is within the range of 140% to 160% and the stretchability in the width direction is within the range of 270% to 290%. The perimeter of the partial foot-covering portion 110 is determined so as to be approximately the same as the foot circumference of a person having an average foot shape and a foot length of 23.5 cm.In addition, since the sleep-promoting leg warmer 100 is knitted on a knitting machine with a cylinder diameter of about 5 inches, the circumference of the partial leg covering part 110 is longer than that knitted on a knitting machine with a cylinder diameter of about 3.5 inches, and the tightness of the middle part of the leg is reduced. In addition, the pressure of the partial leg covering part 110 is preferably within the range of 9.50±0.49 hPa, and more preferably within the range of 9.50±0.16 hPa. The pressure was measured using a PRESSURE CONVERTER AMI3037-10, a round air pack, and an HQL adult female average foot type (average human body size dummy MSX-20 made by Torso, Nanasai Co., Ltd.) in an environment of room temperature 20°C and relative humidity 65%. Specifically, a round air pack was attached to the average foot shape of an HQL adult female, and the sleep-promoting leg warmer 100 was worn on the foot shape, and the measured pressure value displayed on the PRESSURE CONVERTER AMI3037-10 was read one minute later. Here, this measurement was performed three times, and the average value was taken as the pressure. This not only provides a firm texture, but also suppresses vertical expansion and contraction to prevent the wearer from shifting from the normal position. This allows the partial foot covering portion 110 to fit the middle part of the wearer's foot without excessively tightening the middle part of the foot, giving the wearer a comfortable feeling. In addition, the sleep-promoting leg warmer 100 has the above-mentioned structure, which makes it possible to suppress the position shift.

[0029] (2) First clamping part The first clamping portion 120 is a tubular portion having a double knit structure, which covers the toe side of the heel of the wearer and prevents the partial foot covering portion 110 and the ankle covering portion 140 from shifting in position (slipping down, rolling up, etc.) when the sleep-promoting leg warmer 100 is worn. As described above, the first clamping portion 120 has a double knit structure, and therefore has a heat-retaining function due to an air layer existing between the layers. As shown in Figs. 1 and 2, one end of the first clamping portion 120 is connected to the partial foot covering portion 110, and the other end is connected to the connection portion 130. In order to prevent the above-mentioned shifting in position, it is preferable that the knit fabric for knitting the first clamping portion 120 is tighter than the knit fabric for knitting the partial foot covering portion 110 and the ankle covering portion 140. For this reason, the first clamping portion 120 is preferably knitted by flat knitting using a back yarn (FTY). From the same viewpoint, it is preferable that a rubber yarn or a patterned yarn is inserted into the flat knitting. From the same viewpoint, it is preferable that the stretch rate in the axial direction of the knitted fabric is in the range of 240% to 260% and the stretch rate in the width direction is in the range of 190% to 210%. The pressure of the first clamping portion 120 is preferably in the range of 33.20±3.56hPa, and more preferably in the range of 33.20±1.19hPa. This makes it difficult for the partial foot covering portion 110 and the ankle covering portion 140 to become misaligned, and allows the partial foot covering portion 110 and the ankle covering portion 140 to fully exhibit their functions.

[0030] 1 and 2, a cross-shaped raised portion 125 is formed at the sole covering side of the first clamping portion 120 at a position corresponding to the acupressure point for insomnia. As described above, the first clamping portion 120 has a double knit structure, which is composed of an inner knit layer 120a and an outer knit layer 120b as shown in FIG. 3. The raised portion 125 is composed of a first protrusion 125a protruding from the inner knit layer 120a toward the outer knit layer side, and a second protrusion 125b protruding from the outer knit layer 120b toward the inner knit layer side as shown in FIG. 3. As shown in FIG. 3, the first protrusion 125a and the second protrusion 125b are arranged opposite to each other. As shown in FIG. 3 and FIG. 4, 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 composed of a knitted fabric. As shown in FIG. 3, the first protrusion 125a is designed so that the lower end surface of the rectangular portion RG is lower than the lower end surface of the first wing portion W1 and the lower end surface of the second wing portion W2, and the second protrusion 125b is designed so that the upper end surface of the rectangular portion RG is higher than the upper end surface of the first wing portion W1 and the upper end surface of the second wing portion W2. In other words, the first protrusion 125a and the second protrusion 125b are designed so that the rectangular portion RG is thicker than the first wing portion W1 and the second wing portion W2. The first wing portion W1 is a rectangular parallelepiped portion extending from the rectangular portion RG to both sides of the rectangular portion RG along the width direction Dw as shown in FIG. 4. 3, in the first protrusion 125a and the second protrusion 125b, the lower end surface or upper end surface of the first wing W1 is at the same height as the lower end surface or upper end surface of the second wing W2. As described above, the first protrusion 125a is designed so that the lower end surface of the first wing W1 is higher than the lower end surface of the rectangular portion RG, and the second protrusion 125b is designed so that the upper end surface of the first wing W1 is lower than the upper end surface of the rectangular portion RG. In other words, the first protrusion 125a and the second protrusion 125b are designed so that the first wing W1 is thinner than the rectangular portion RG.The second wing portion W2 is a rectangular parallelepiped portion extending from the rectangular portion RG in a direction Dl perpendicular to the width direction Dw, that is, in the depth direction (direction passing through the heel and toe) on both sides of the rectangular portion RG, as shown in FIG. 4. As shown in FIG. 3, the lower end surface or upper end surface of the second wing portion W2 in the first protrusion portion 125a and the second protrusion portion 125b is at the same height as the lower end surface or upper end surface of the second wing portion W2. As described above, the lower end surface of the first wing portion W1 in the first protrusion portion 125a is designed to be higher than the lower end surface of the rectangular portion RG, and the upper end surface of the first wing portion W1 in the second protrusion portion 125b is designed to be lower than the upper end surface of the rectangular portion RG. In other words, the second wing portion W2 in the first protrusion portion 125a and the second protrusion portion 125b is designed to be thinner than the rectangular portion RG. By forming the first protrusion 125a and the second protrusion 125b as described above, twelve corners CN are formed in each of the first protrusion 125a and the second protrusion 125b. Of these, four corners CN are formed by the rectangular portion RG, and eight corners CN are formed by the first wing portion W1 and the second wing portion W2.

[0031] By forming the raised portion 125 as described above, when the wearer wears the product and walks, the raised portion 125 formed by the first protrusion 125a and the second protrusion 125b rises inward (toward the skin) (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 higher than the upper end surface of the first wing portion formed by the first wing portion W1 of the first protrusion 125a and the first wing portion W1 of the second protrusion 125b, and the upper end surface of the second wing portion formed by the second wing portion W2 of the first protrusion 125a and the second wing portion W2 of the second protrusion 125b). At the same time, 12 corners are formed at the positions corresponding to the corners CN of the first protrusion 125a and the second protrusion 125b on the raised portion, and these corners can efficiently stimulate the acupressure points for insomnia.

[0032] When forming the protrusions 125a, 125b from knitted fabric, it is preferable to form the protrusions 125a, 125b as follows. Specifically, the protrusions 125a, 125b are knitted by combining a knitting method such as pile knitting and a change in yarn such as thick yarn. This allows the first protrusion 125a to be integrated with the inner knitted fabric layer 120a and the second protrusion 125b to be integrated with the outer knitted fabric layer 120b, and prevents the protrusions 125a, 125b from shifting in position due to poor adhesion or the like without increasing the number of steps for forming the protrusions 125a, 125b.

[0033] A more specific knitting method is shown in Figure 5. The area indicated by the circle and triangle marks in Figure 5 (hereinafter sometimes referred to as the "first area") is a flat knit area, knitted with a front yarn, a back yarn, and a rubber yarn. The rubber yarn is inserted in the area indicated by the triangle mark.

[0034] The area indicated by row numbers 3-11 / column numbers 1-4 (hereinafter sometimes referred to as the "21st area"), the area indicated by row numbers 12-22 / column numbers 5-8 (hereinafter sometimes referred to as the "22nd area"), the area indicated by row numbers 23-31 / column numbers 1-4 (hereinafter sometimes referred to as the "23rd area"), the area indicated by row numbers 3-11 / column numbers 129-132 (hereinafter sometimes referred to as the "24th area"), the area indicated by row numbers 12-22 / column numbers 125-128 (hereinafter sometimes referred to as the "25th area"), and the area indicated by row numbers 23-31 / column numbers 129-132 (hereinafter sometimes referred to as the "26th area") are knitted with face yarn, back yarn, rubber yarn, and pseudo pile yarn. In these areas, the pseudo pile yarn is woven in the gray areas but not in the black areas. The black areas have no artificial pile yarn woven in, which gives the fabric a pile-like texture and thickness. Also, the rubber yarn is not woven in these areas, so it lies on top of them. Because the rubber yarn is not woven in this way, it is not crushed, which gives the fabric thickness in those areas.

[0035] The area indicated by row numbers 12-22 / column numbers 1-4 (hereinafter sometimes referred to as "area 31") and the area indicated by row numbers 12-22 / column numbers 129-132 (hereinafter sometimes referred to as "area 32") are knitted with face yarn, back yarn, rubber yarn, and pseudo pile yarn. In these areas, the pseudo pile yarn is knitted in the light gray areas, but not in the dark gray areas. This is the same as the above-mentioned areas 21-26, but these areas are further changed from flat knitting to pile knitting. As a result, these areas are thicker than areas 21-26. In other words, the relationship of the thickness of each of the above-mentioned areas is as follows.

[0036] 31st area = 32nd area> 21st area = 22nd area = 23rd area = 24th area = 25th area = 26th area> 1st area.

[0037] Similarly to regions 21 to 26, no rubber thread is woven into regions 31 and 32, so the rubber thread lies above these regions. Since the rubber thread is not woven into these regions, it is not crushed, and the area becomes thicker.

[0038] (3) Connection The connecting part 130 is an annular part having a single knit structure, and plays a role of connecting the first clamping part 120 and the ankle covering part 140. From the viewpoint of not disturbing the sleep of the wearer, it is preferable that the connecting part 130 has no step and does not make the wearer feel tight. Specific examples of the connecting part 130 include a heat fusion part and a sewing part. It is preferable that the connecting part 130 is located closer to the toe side than the heel of the wearer when the sleep-promoting leg warmer 100 is worn. This is because it is preferable that the connecting part 130 is located in a less sensitive part of the wearer's foot when the sleep-promoting leg warmer 100 is worn, from the viewpoint of not causing discomfort to the wearer.

[0039] (4) Ankle Coverage The ankle covering part 140 is a tubular part having a single knit structure, and is a part for covering the wearer's ankle and part of the heel. As shown in Figs. 1 and 2, the ankle covering part 140 is connected to the first clamping part 120 via a connecting part 130, and the opposite side is connected to the second clamping part 150. In addition, from the viewpoint of providing moderate heat retention, the ankle covering part 140 is preferably knitted by pile knitting or the like. In addition, from the viewpoint of aligning the protuberance 125 of the first clamping part 120, it is preferable that the ankle covering part 140 is bent so as to follow the shape of the ankle and heel during sleep. It is preferable that the ankle covering part 140 has a narrowed knitting area between the entire circumference knitting areas of the ankle covering part 140, and a widened knitting area may be provided following the narrowed knitting area. In addition, the pressure of the ankle covering part 140 is Within the range of 8.17±2.62hPa It is preferred that Within the range of 8.17±0.87hPa It is more preferable that:

[0040] (5) Second clamping section The second clamping portion 150 is a tubular portion having a single knit fabric, which covers the portion located above the wearer's ankle and prevents the ankle covering portion 140 and the shin covering portion 160 from shifting out of position (slipping down, rolling up, etc.) when the sleep-promoting leg warmers 100 are worn. As shown in Figures 1 and 2, one end of the second clamping portion 150 is connected to the ankle covering portion 140, and the other end is connected to the shin covering portion 160. The pressure of the second clamping portion 150 is Within the range of 5.63±0.51hPa It is preferred that Within the range of 5.63±0.17hPa It is more preferable that:

[0041] As shown in Figs. 1 and 2, an acupoint stimulating portion 155 is formed on the side of the second clamping portion 150 at a position corresponding to the Sanyinjiao acupoint.

[0042] (6) Shin guard The shin covering part 160 is a tubular part with a double knit structure, and is a part for covering the shins of the wearer. As described above, because the shin covering part 160 has a double knit structure, it has a heat retention function due to the air layer that exists between the layers. As shown in Figures 1 and 2, one end of the shin covering part 160 is connected to the second pressure-clamping part 150, and the other end forms the base end of the sleep-promoting leg warmer 100. In order to prevent the shin covering part 160 from shifting out of position (slipping down, rolling up, etc.) when the sleep-promoting leg warmer 100 is worn, the pressure of the shin covering part 160 is Within the range of 4.80±3.13hPa It is preferred that Within the range of 4.80±1.04hPa It is more preferable that:

[0043] <Compression ratio of each part> As mentioned above, preferred pressures are specified for each part, and the ratios of these, i.e., pressure of shin covering part 160:pressure of ankle covering part 140:pressure of partial foot covering part 110:pressure of second clamping part 150:pressure of first clamping part 120, are preferably 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. In other words, it is preferable that the pressure of the first clamping portion 120 is higher than the pressure of the partial foot covering portion 110, the pressure of the first clamping portion 120 is higher than the pressure of the ankle covering portion 140, the pressure of the ankle covering portion 140 is higher than the pressure of the second clamping portion 150, and the pressure of the second clamping portion 150 is higher than the pressure of the shin covering portion 160.

[0044] <Specific method for forming the sleep-promoting leg warmer according to the embodiment of the present invention> The partial foot covering portion 110 and the first pressed portion 120 can be formed, for example, as follows: (i) knitting from the end of the first pressed portion 120 on the connection portion side to the end of the first pressed portion 120 on the partial foot covering portion side to form an outer knitted layer 120b of the first pressed portion 120, then switching yarn and knitting from the end of the partial foot covering portion 110 on the first pressed portion side to the tip of the partial foot covering portion 110 to form an outer knitted layer of the partial foot covering portion 110, and then knitting the partial foot covering portion 110 as is. The inner knitted layer of the partial foot covering portion 110 is knitted by knitting from the tip of the covering portion 110 to the end of the partial foot covering portion 110 on the first clamping portion side, and then the yarn is switched and knitted from the end of the first clamping portion 120 on the partial foot covering portion side to the end of the first clamping portion 120 on the connection portion side to knit the inner knitted layer 120a of the first clamping portion 120. The inner knitted layers of the partial foot covering portion 110 and the first clamping portion 120 are knitted by knitting the outer knitted layers of the partial foot covering portion 110 and the first clamping portion 120. (ii) knitting from the end of the first clamping portion 120 on the connection portion side to the end of the first clamping portion 120 on the partial foot covering portion side to knit an inner knitted layer 120a of the first clamping portion 120, then switching yarn and knitting from the end of the partial foot covering portion 110 on the first clamping portion side to the tip of the partial foot covering portion 110 to knit an inner knitted layer of the partial foot covering portion 110, and then knitting from the tip of the partial foot covering portion 110 to the tip of the partial foot covering portion 110 to knit an inner knitted layer of the partial foot covering portion 110. Examples of methods include knitting the outer knitted layer of the partial foot covering part 110 to the end on the first clamping part side, switching yarn and knitting from the end of the first clamping part 120 on the partial foot covering part side to the end of the first clamping part 120 on the connection part side to knit the outer knitted layer 120b of the first clamping part 120, and pushing the inner knitted layers of the partial foot covering part 110 and the first clamping part 120 into the outer knitted layers of the partial foot covering part 110 and the first clamping part 120.

[0045] The ankle covering part 140, the second clamping part 150 and the shin covering part 160 can be formed, for example, as follows: (i) knitting the ankle covering part 140 from the end of the ankle covering part 140 on the connection part side to the end of the ankle covering part 140 on the second clamping part side, then switching the yarn and knitting the second clamping part 150 from the end of the second clamping part 150 on the ankle covering part side to the end of the second clamping part 150 on the shin covering part side, and then knitting the second clamping part 150 with the yarn Then, the outer knitted layer of the shin covering part 160 is knitted from the end of the shin covering part 160 on the second pressing portion side to the base end of the shin covering part 160, and the inner knitted layer of the shin covering part 160 is knitted by continuing the knitting from the base end of the shin covering part 160 to the end of the shin covering part 160 on the second pressing portion side. The inner knitted layer of the shin covering part 160 is then pushed into the outer knitted layer of the shin covering part 160 and the inner knitted layer is knitted at the end on the second pressing portion side. and (ii) a method in which the inner knitted layer of the shin covering part 160 is knitted from the end of the shin covering part 160 on the second clamping portion side to the base end of the shin covering part 160 to knit the outer knitted layer of the shin covering part 160, and then the base end of the shin covering part 160 is knitted from the end of the shin covering part 160 on the second clamping portion side to the end of the shin covering part 160 on the second clamping portion side to knit the outer knitted layer of the shin covering part 160, and then the yarn is switched and knitted from the end of the second clamping part 150 on the shin covering part side to the end of the second clamping part 150 on the ankle covering part side to knit the second clamping part 150, and then the yarn is switched again and knitted from the end of the ankle covering part 140 on the second clamping portion side to the end of the ankle covering part 140 on the connection portion side to knit the ankle covering part 140, and then the inner knitted layer of the shin covering part 160 is pushed into the outer knitted layer of the shin covering part 160 and the inner knitted layer and the outer knitted layer are connected at the end on the second clamping portion side.

[0046] The method for connecting the first clamping part 120 and the ankle covering part 140 is as explained above in the section "(3) Connection part."

[0047] <Features of the sleep-promoting leg warmer according to the embodiment of the present invention> (1) The sleep-promoting leg warmers 100 according to the embodiment of the present invention are provided with a raised portion 125 at a position on the first clamping portion 120 that corresponds to the acupressure point for insomnia, and a corner is formed on the raised portion 125. Therefore, when the sleep-promoting leg warmers 100 are worn before going to bed or when the wearer walks lightly before going to bed, the wearer can more effectively sense that the acupressure point for insomnia is being stimulated than with conventional leg warmers.

[0048] (2) In the sleep-promoting leg warmer 100 according to the embodiment of the present invention, the protruding portion 125 is composed of a first protruding portion 125a protruding from the inner knitted layer 120a toward the outer knitted layer side, and a second protruding portion 125b protruding from the outer knitted layer 120b toward the inner knitted layer side. Therefore, in the sleep-promoting leg warmer 100, even if the yarn comes out during knitting of the protruding portions 125a and 125b, the yarn can be prevented from being exposed to the skin side or the ground surface side. Therefore, in the sleep-promoting leg warmer 100, the yarn knitting the protruding portions 125a and 125b can be prevented from being caught on the nails or fingers of the wearer, or on the floor. Therefore, in the sleep-promoting leg warmer 100, it is easy to wear and the yarn is not easily unraveled.

[0049] (3) In the sleep-promoting leg warmer 100 according to the embodiment of the present invention, the pressure ratios of the shin covering part 160, the ankle covering part 140, the partial foot covering part 110, the second clamping part 150, and the first clamping part 120 were 4.80±3.13hPa:8.17±2.62hPa:9.50±0.49hPa:5.63±0.51hPa:33.20±3.56hPa. As a result of intensive research by the inventors of the present application, it has become clear that the sleep-promoting leg warmer 100 having such a pressure ratio is unlikely to slip off from the wearer's feet, ankles, the upper part of the ankles, and the shins while falling asleep or staying asleep, without compressing the wearer's feet, ankles, the upper part of the ankles, and the shins to an uncomfortable degree. Therefore, the sleep-promoting leg warmers 100 are unlikely to slip off from the feet, ankles, upper ankle areas and shins while falling asleep or staying asleep, and can provide the wearer with a comfortable way to fall asleep and stay asleep.

[0050] (4) In the sleep-promoting leg warmer 100 according to the embodiment of the present invention, there is no region of stronger pressure than the partial foot covering part 110 on the side opposite the first clamping part of the partial foot covering part 110. On the other hand, in conventional foot wearing devices, a region of stronger pressure than the part corresponding to the partial foot covering part is often provided on the tip side of the part corresponding to the partial foot covering part to prevent the device from slipping when worn.

[0051] <Modification> (A) Although the sleep-promoting leg warmers 100 according to the above embodiment were designed with the wearer in mind whose foot length was within the range of 22 cm to 25 cm, the size range may be designed in increments of 1 cm. That is, for example, three sizes may be designed for wearers whose foot length is within the range of 22 cm to 23 cm, 23 cm to 24 cm, and 24 cm to 25 cm.

[0052] (B) In the sleep-promoting leg warmer 100 according to the previous embodiment, the length of the partial foot-covering portion 110 is set not to exceed the base of the little toe of a person having an average foot shape and a foot length within the range of 22 cm to 25 cm, but it may be set to a length that covers the tip of the little toe of a person having an average foot shape and a foot length of 22 cm. In this case, when a person having an average foot shape and a foot length of 25 cm wears the sleep-promoting leg warmer 100, the part up to the base of the little toe of the person will be covered.

[0053] (C) In the sleep-promoting leg warmer 100 according to the previous 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 warmer 100 may be designed to cover at least a portion of the arch, or may be designed to cover at least the entire arch.

[0054] (D) In the sleep-promoting leg warmer 100 according to the previous embodiment, the first clamping portion 120 is provided between the partial foot covering portion 110 and the connecting portion 130 in order to prevent the partial foot covering portion 110 and the ankle covering portion 140 from shifting out of position, but the first clamping portion may be provided at the toe side of the partial foot covering portion 110 in order to prevent only the partial foot covering portion 110 from shifting out of position, or the first clamping portion may be provided inside the ankle covering portion 140 in order to prevent only the ankle covering portion 140 from shifting out of position. In the former case, it is preferable to use a knitting structure similar to that of a typical single-knit open-toe sock, and in the latter case, it is preferable to use a knitting structure similar to that of a double-welted pouch portion as disclosed in Japanese Patent No. 6195139.

[0055] (E) In the sleep-promoting leg warmer 100 according to the previous embodiment, the partial leg-covering portion 110, the first clamping portion 120, and the shin-covering portion 160 have a double knit structure, but these portions 110, 120, and 160 may have a single knit structure. In such a case, the partial leg-covering portion 110 is preferably knitted with a highly heat-retaining knit such as pile knitting, knitted with highly heat-retaining yarn such as acrylic yarn or wool, or knitted with moisture-absorbing heat-generating yarn such as eks (registered trademark).

[0056] (F) In the sleep-promoting leg warmer 100 according to the previous embodiment, the partial foot covering portion 110, the first clamping portion 120, and the shin covering portion 160 have a double knit structure, but these portions 110, 120, and 160 may have a multi-knit structure of three or more layers. In such a case, yarns of different materials may be used for each knit layer to adjust the heat retention, etc.

[0057] (G) In the sleep-promoting leg warmer 100 according to the previous embodiment, the connection portion 130, the ankle covering portion 140 and the second clamping portion 150 have a single knit structure, but these portions 130, 140, 150 may also have a double knit structure.

[0058] (H) Although not specifically mentioned in the previous embodiment, the heel side region of the partial foot covering part 110 may be knitted into a heat generating knitted fabric or a heat retaining knitted fabric, and the partial foot covering part 110 may be knitted into a knitted fabric with gradually lower heat generating or heat retaining properties toward the tip side of the partial foot covering part 110. By knitting the partial foot covering part 110 in this way, efficient heat dissipation can be achieved by increasing the body temperature of the wearer while preventing the area around the toes, which needs heat dissipation, from becoming too warm.

[0059] (I) In the sleep-promoting leg warmer 100 according to the previous embodiment, the shape of the raised portion 125 is a cross-shaped column, but the shape of the raised portion is not particularly limited as long as it has corners, and may be, for example, a polygonal shape such as a triangular column, a square column, a pentagonal column, a hexagonal column, an octagonal column, or a star-shaped column, or a cylindrical shape. The corners of the raised portion 125 do not have to be recognizable only in planar perspective, but only need to be recognizable when viewed from all 360° directions. In addition, the corners in such a shape may be rounded, but from the viewpoint of effectively stimulating the acupressure points for sleep loss, it is preferable that the radius of the rounded corner is 15 mm or less. The lower limit of the radius of the rounded corner is not particularly specified, but is, for example, 0.1 mm.

[0060] (J) Although the sleep-promoting leg warmers 100 according to the above embodiment are provided with only one relatively large protuberance 125, a plurality of relatively small protuberances may be provided.

[0061] (K) In the sleep-promoting leg warmers 100 according to the previous embodiment, the first protrusion 125a was designed so that the lower end surface of the rectangular portion RG was lower than the lower end surface of the first wing portion W1 and the lower end surface of the second wing portion W2, and the second protrusion 125b was designed so that the upper end surface of the rectangular portion RG was higher than the upper end surface of the first wing portion W1 and the upper end surface of the second wing portion W2. However, the lower end surface of the rectangular portion RG in the first protrusion 125a may be at the same height as the lower end surface of the first wing portion W1 and the lower end surface of the second wing portion W2, and the upper end surface of the rectangular portion RG in the second protrusion 125b may be at the same height as the upper end surface of the first wing portion W1 and the upper end surface of the second wing portion W2 (i.e., the first protrusion 125a and the second protrusion 125b may be at the same height as the upper end surface of the first wing portion W1 and the upper end surface of the second wing portion W2). The opposing surfaces of the protrusion 125b may be flat surfaces. In other words, the rectangular portion RG may have the same thickness as the first wing W1 and the second wing W2 in the first protrusion 125a and the second protrusion 125b.) The lower end surface of the rectangular portion RG in the first protrusion 125a may be higher 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 may be lower than the upper end surface of the first wing W1 and the upper end surface of the second wing W2 (i.e., the rectangular portion RG may be thinner than the first wing W1 and the second wing W2 in the first protrusion 125a and the second protrusion 125b).

[0062] (L) In the sleep-promoting leg warmer 100 according to the previous embodiment, the first protrusion 125a protrudes from the inner knitted layer 120a toward the outer knitted layer side, and the second protrusion 125b protrudes from the outer knitted layer 120b toward the inner knitted layer side, but the first protrusion may protrude from the inner knitted layer 120a toward the inside, i.e., the skin side, and the second protrusion may protrude from the outer knitted layer 120b toward the inner knitted layer side, or the first protrusion may protrude from the inner knitted layer 120a toward the outer knitted layer side, and the second protrusion may protrude from the outer knitted layer 120b toward the outside, i.e., the opposite side to the skin side, or the first protrusion may protrude from the inner knitted layer toward the inside, i.e., the skin side, and the second protrusion 125b may protrude from the outer knitted layer 120b toward the outside, i.e., the opposite side to the skin side. In any of the above cases, the first protrusion and the second protrusion must overlap in a plan view.

[0063] (M) In the sleep-promoting leg warmer 100 of the previous embodiment, the first clamping portion 120 has a double knit structure with protrusions 125a, 125b formed therebetween, but the first clamping portion 120 may have a single knit structure with protrusions formed on the inside (skin side) or outside.

[0064] (N) In the sleep-promoting leg warmer 100 according to the previous embodiment, the angle CN between the first wing W1 and the second wing W2 of the protrusions 125a and 125b is a right angle, but instead of the protrusions 125a and 125b, protrusions 225a and 225b may be provided in which the angle CN between the first wing W1 and the second wing W2 is an acute angle, as shown in FIG. 6. The angle CN may be an obtuse angle, but if the obtuse angle is too large, the effect of the present invention will be reduced, so this is not preferred. The angle CN between the rectangular portion RG of the protrusions 125a and 125b is a right angle, but the angle CN between the rectangular portion RG may be an acute angle. The angle CN may be an obtuse angle, but if the obtuse angle is too large, the effect of the present invention will be reduced, so this is not preferred.

[0065] (O) In the sleep-promoting leg warmers 100 according to the previous embodiment, the raised portions 125 are made of knitted fabric, but the raised portions 125 may be made of, for example, polyvinyl chloride resin, silicone resin, elastomer resin, rubber, etc. In such cases, the raised portions 125 may be made of resin or rubber containing magnetic particles or magnetic powder in order to obtain the health benefits of magnetism.

[0066] (P) In the sleep-promoting leg warmer 100 according to the previous embodiment, the raised portion 125 stimulates the acupuncture point for insomnia with pressure, but the raised portion may stimulate the acupuncture point for insomnia with heat, with cold, or with electricity. The raised portion may stimulate the acupuncture point for insomnia with pressure and heat. In order to provide the raised portion with a heat stimulating function, it is necessary to knit the raised portion using heat-generating yarn such as acrylate fiber, wool, cupra (registered trademark), rayon (registered trademark), etc.

[0067] (Q) In the sleep-promoting leg warmers 100 according to the previous embodiment, the raised portions 125 are provided at positions corresponding to the acupressure points for insomnia, but the raised portions may also be provided at positions corresponding to acupressure points such as Sanyinjiao and Yongquan.

[0068] (R) In the sleep-promoting leg warmer 100 according to the previous embodiment, a cross-shaped protuberance 125 is formed on the sole-covering side of the first clamping portion 120, but an X-shaped protuberance may be formed instead. In an X-shaped protuberance, the first and second wings do not extend along the axial and width directions as shown in Fig. 2, but extend, for example, along a direction inclined by 45° from those directions. Note that in an X-shaped protuberance, the first and second wings may extend along a direction other than the above.

[0069] (S) In the sleep-promoting leg warmer 100 according to the previous embodiment, the partial leg-covering portion 110 was designed to be suitable for people with average foot shapes and foot lengths in the range of 22 cm to 25 cm, but may also be designed to be suitable for people with other foot shapes and lengths.

[0070] The above-described modified examples may be adopted individually or in appropriate combinations within a range that does not cause any contradiction.
