[0004] However, muscles such as the triceps surae are present below the knee, and because these muscles expand and contract as the knee bends and straightens when walking, etc., leg attachments that cover the knee or the area near the knee are prone to slipping off when walking, etc. For this reason, even if the leg attachment has a section for stimulating acupressure points near the knee, it is difficult to continuously stimulate the acupressure points near the knee.

[0005] An object of the present invention is to provide a leg attachment that can easily continue to stimulate acupressure points in the legs near the knees even while wearing the attachment and walking, etc.

[0006] A leg attachment according to a first aspect of the present invention is a leg attachment that covers part or all of the leg and includes an acupressure point stimulation portion, a peripheral portion, and a slippage prevention portion. The leg attachment is made of a knitted structure. That is, the leg attachment is a knitted fabric. The "leg" referred to here refers to the area from the base of the thigh to the toes of the lower leg. The leg attachment may also include a panty portion. Examples of leg attachments include socks (socks, knee-high socks, over-the-knee socks, etc.), knee supports, leg warmers, stockings, and tights. The acupressure point stimulation portion is formed from a first knitted fabric. The first knitted fabric is knitted by plating knitting using a first front yarn and a back yarn. The acupressure point stimulation portion is positioned to cover at least one acupressure point present on the leg when the leg attachment is worn. The acupressure point stimulation portion may be sheet-shaped or comprised of multiple protrusions. The peripheral portion is formed from a second knitted fabric. The second knitted fabric is a knitted fabric knitted by plating knitting with a second front yarn and a back yarn. This second knitted fabric has a lower acupoint stimulation property than the first knitted fabric. This peripheral portion is formed at least circumferentially outside the acupoint stimulation portion, i.e., in a wale different from the acupoint stimulation portion of the course in which the acupoint stimulation portion is formed. The slippage suppression portion is formed of a third knitted fabric on the opening side of the acupoint stimulation portion and at least one side opposite the opening side.

[0007] As mentioned above, the leg attachment has a slippage prevention section formed on at least one side of the acupressure stimulation section, on the opening side of the leg attachment and on the opposite side of the opening side, making it easy to continue stimulating the acupressure points around the knees even when wearing the leg attachment and walking.

[0008] A leg attachment according to a second aspect of the present invention is the leg attachment according to the first aspect, wherein the acupoint stimulation portion is positioned to cover at least one of the acupoints Xuehai, Yinlingquan, Zhiyangguan, and Zusanli when attached.

[0009] Therefore, this leg attachment can stimulate at least one of the acupressure points of Xuehai, Yinlingquan, Zhiyangguan and Zusanli to warm the legs efficiently.

[0010] A leg attachment according to a third aspect of the present invention is the leg attachment according to the first or second aspect, wherein the first face yarn is a first heat-generating yarn. The first heat-generating yarn has heat-generating properties. The second face yarn is a second heat-generating yarn. The second heat-generating yarn has lower heat-generating properties than the first heat-generating yarn.

[0011] As described above, in this leg attachment, the first surface yarn is the first heat-generating yarn, and the second surface yarn is the second heat-generating yarn that has lower heat-generating properties than the first heat-generating yarn. Therefore, with this leg attachment, the acupressure points near the knee can be thermally stimulated at a higher temperature than the surrounding area.

[0012] A leg attachment according to a fourth aspect of the present invention is the leg attachment according to the third aspect, wherein the first and second heat-generating yarns contain at least one moisture-absorbing heat-generating fiber selected from the group consisting of acrylate fibers, wool, cotton, cupra, and rayon, and wherein the proportion of the moisture-absorbing heat-generating fiber contained in the first heat-generating yarn is greater than the proportion of the moisture-absorbing heat-generating fiber contained in the second heat-generating yarn.

[0013] Therefore, with this leg attachment, the amount of heat generated in the acupoint stimulation portion and the surrounding area can be easily adjusted without affecting the relationship between the amount of heat generated in the acupoint stimulation portion and the surrounding area.

[0014] A leg attachment according to a fifth aspect of the present invention is the leg attachment according to the fourth aspect, wherein the first heat-generating yarn and the second heat-generating yarn are yarns made of the same material containing the same moisture-absorbing heat-generating fiber, and the proportion of the moisture-absorbing heat-generating fiber contained in the first heat-generating yarn is greater than the proportion of the moisture-absorbing heat-generating fiber contained in the second heat-generating yarn.

[0015] Therefore, when the wearer puts on the leg attachment, it is possible to reduce the possibility that the wearer will feel uncomfortable due to the different material.

[0016] A leg attachment according to a sixth aspect of the present invention is the leg attachment according to any one of the first to fifth aspects, wherein the first knitted fabric is formed in a different wale on the same course as the second knitted fabric.

[0017] Therefore, in this leg attachment, the acupressure stimulation portion and the surrounding area can be knitted as areas with different heat generation properties by switching the surface yarns.

[0018] A leg attachment according to a seventh aspect of the present invention is the leg attachment according to any one of the first to sixth aspects, further comprising a narrow gap knitted fabric. The narrow gap knitted fabric is formed between the first knitted fabric and the second knitted fabric. In this narrow gap knitted fabric, the first face yarn and the second face yarn are knitted together. This narrow gap knitted fabric is also called a double-edged knitted fabric. Furthermore, it is preferable that the narrow gap knitted fabric is formed in one or more wales, and more preferably in two or more wales.

[0019] Therefore, with this leg attachment, defects such as yarn coming off at the transition area between the acupoint stimulation area and the surrounding area can be suppressed. Furthermore, when the first face yarn is the above-mentioned first heat-generating yarn and the second face yarn is the second heat-generating yarn, a clear temperature difference can be created between the acupoint stimulation area and the surrounding area, allowing for more optimal thermal stimulation of the acupoints. Furthermore, the greater the number of wales that form the narrow knitted fabric, the more defects such as yarn coming off can be suppressed.

[0020] A leg attachment according to an eighth aspect of the present invention is the leg attachment according to any one of the first to seventh aspects, wherein the first knitted fabric is knitted by plating knitting with a first front yarn, a second front yarn, and a back yarn. That is, in the leg attachment according to this aspect, the entire first knitted fabric is a double-edged knitted fabric.

[0021] Therefore, with this leg attachment, it is possible to prevent defects such as yarn coming loose from the first knitted fabric.

[0022] A leg attachment according to a ninth aspect of the present invention is the leg attachment according to any one of the first to eighth aspects, wherein the third knitted fabric is knitted with at least one of a first face yarn, a second face yarn, and a third face yarn. Note that the third face yarn is different from the first face yarn and the second face yarn. The third knitted fabric has higher extensibility in the wale direction than at least one of the first knitted fabric and the second knitted fabric.

[0023] As described above, in this leg attachment, the third knitted fabric has higher stretchability in the wale direction than at least one of the first knitted fabric and the second knitted fabric. Therefore, when the wearer moves their legs, such as walking while wearing the leg attachment, the third knitted fabric stretches, thereby preventing the tensile force from being transmitted to the first knitted fabric and the second knitted fabric, and preventing the first knitted fabric and the second knitted fabric from slipping off the leg.

[0024] A leg attachment according to a tenth aspect of the present invention is the leg attachment according to any one of the first to ninth aspects, wherein the slippage-suppressing portion has a fourth knitted fabric. The fourth knitted fabric has a higher tightening force than at least one of the first knitted fabric and the second knitted fabric. The fourth knitted fabric may be (i) a knitted fabric knitted with elastic yarn insertion knitting, or (ii) a knitted fabric knitted with plating knitting using a third face yarn and a back yarn, in which the third face yarn is more elastic than the first face yarn and the second face yarn and has particularly high contractile force, or a knitted fabric knitted with tuck knitting, which has low elasticity, or a knitted fabric knitted with rib knitting, which has high contractile force.

[0025] Therefore, when the leg attachment is worn, the fourth knitted fabric fastens the wearer's leg, thereby preventing the leg attachment, particularly the first knitted fabric and the second knitted fabric, from shifting.

[0026] A leg attachment according to an eleventh aspect of the present invention is the leg attachment according to any one of the first to tenth aspects, and has an inner layer and an outer layer. The inner layer is the layer that comes into contact with the skin, i.e., the innermost layer. The outer layer is disposed outside the inner layer. Any number of outer layers may be provided. The inner layer is provided with an acupoint stimulation portion, a peripheral portion, and a slippage prevention portion.

[0027] Therefore, with this leg attachment, by selecting the knitting structure of the outer layer, it is possible to improve heat retention, improve comfort when wearing it, and adjust the degree of tightness.

[0028] A twelfth aspect of the present invention relates to the leg attachment of the second aspect, wherein the acupoint stimulating portion includes a first acupoint stimulating region and a second acupoint stimulating region, the first acupoint stimulating region covering at least one of the Xuehai and Yinlingquan acupoints when the leg attachment is worn, and the second acupoint stimulating region covering at least one of the Zhiyangguan and Zusanli acupoints when the leg attachment is worn.

[0029] The Xuehai and Yinlingquan points are located on the inside of the leg, while the Zhiyangguan and Zusanli points are located on the outside of the leg. In other words, this leg attachment can have acupoint stimulation sections divided into an area for stimulating the acupoints on the inside of the leg and an area for stimulating the acupoints on the outside of the leg. This allows the width of the acupoint stimulation area in the course direction to be shortened. This leg attachment can therefore reduce the effort required for arranging the acupoint stimulation section, and can efficiently thermally stimulate the acupoints and their surrounding areas while minimizing thermal stimulation of areas other than the acupoints and their surrounding areas. Furthermore, the temperature difference between the acupoint stimulation section and the surrounding area allows for effective thermal stimulation of the acupoints.

[0030] A leg attachment according to a thirteenth aspect of the present invention is the leg attachment according to the twelfth aspect, wherein the first acupoint stimulation area covers both the Xuehai and Yinlingquan acupoints when the leg attachment is worn, and the second acupoint stimulation area covers both the Zhiyangguan and Zusanli acupoints when the leg attachment is worn.

[0031] With this leg attachment, two acupressure points on the legs can be stimulated in each acupressure point stimulation area, and the acupressure points around the knees can be stimulated efficiently.

[0032] A leg attachment according to a fourteenth aspect of the present invention is the leg attachment according to the second aspect, wherein the acupoint stimulation portion covers all of the acupoints of Xuehai, Yinlingquan, Zhiyangguan and Zusanli when the leg attachment is worn.

[0033] That is, in this leg attachment, the acupoint stimulating portions are all integrated into one, which significantly reduces the effort required to assemble the acupoint stimulating portions.

[0036] <Configuration of Cold Weather Legwear According to an Embodiment of the Present Invention> Cold weather legwear 100 according to an embodiment of the present invention is legwear generally called over-the-knee socks, and is a knitted fabric having a generally V-shaped tube shape with one end (the end on the opening side) open. Note that this cold weather legwear 100 was invented for the purpose of warming the legs.

[0037] 1 and 2, the cold weather legwear 100 according to the embodiment of the present invention is mainly composed of a foot covering portion 110, a clamping portion 120, and a partial leg covering portion 130. These components will be described in detail below.

[0038] (1) Foot Covering Section The foot covering section 110 is a tubular section having a pile knit structure and is a section for covering the wearer's foot. As described above, the foot covering section 110 has a pile knit structure, and therefore has a heat-retaining function due to the air layer present between the pile loops. As shown in Figures 1 and 2, one end of the foot covering section 110 is closed, and the other end is connected to the clamping section 120. From the viewpoint of gently tightening the foot covering section 110 so as not to cause discomfort to the wearer, it is also preferable that the foot covering section 110 be knitted using a zigzag knitting method without using a backing yarn (FTY). From the same viewpoint, it is also preferable that a rubber yarn be inserted into the zigzag knitting method.

[0039] (2) Clamping Section The clamping section 120 is a tubular section having a single knit fabric that covers the area slightly above the wearer's ankle and prevents the partial leg covering section 130 from shifting position (slipping down, etc.) when the cold weather legwear 100 is worn. As shown in Figures 1 and 2, one end of the clamping section 120 is connected to the foot covering section 110, and the other end is connected to the partial leg covering section 130. Also, as shown in Figures 1 and 2, a Sanyinjiao stimulating section 122 is formed on the side of the clamping section 120 at a position corresponding to the Sanyinjiao acupoint.

[0040] (3) Partial leg-covering portion The partial leg-covering portion 130 is a tubular portion having a double knitted structure, and is intended to cover the wearer's leg from above the ankle to slightly above the knee, and is mainly composed of an outer knitted layer (not shown) and an inner knitted layer Li. The outer knitted layer is literally disposed on the outside of the inner knitted layer Li.

[0041] The outer knitted fabric layer is knitted into a rib knit fabric using pile sinker knitting with skipped elastic yarns. That is, the outer knitted fabric layer has multiple ribs and multiple grooves arranged alternately in the circumferential direction. One end of this outer knitted fabric layer is connected to the press-fit portion 120, and the other end is open to form the opening of the cold weather legwear 100.

[0042] The inner knitted layer Li is the layer that comes into contact with the skin when the cold weather legwear 100 is worn. As shown in FIGS. 1 and 2 , it is primarily composed of an inner acupoint stimulating portion 131a, an outer acupoint stimulating portion 131b, a front shin covering portion 132a, a rear shin covering portion 132b, a slippage prevention portion 133, an above-knee covering portion 134, and an opening portion 135. For ease of explanation, the inner acupoint stimulating portion 131a, the outer acupoint stimulating portion 131b, the front shin covering portion 132a, and the rear shin covering portion 132b may be collectively referred to as the "central covering portion." These components are described in detail below. As mentioned above, the partial leg covering portion 130 has a double knitted structure, which provides heat retention through the air layer present between the layers. As shown in FIGS. 1 and 2 , one end of the inner knitted layer Li is connected to the clamping portion 120, and the other end is open.

[0043] (3-1) Medial Acupoint Stimulation Section As shown in FIG. 1, the medial acupoint stimulation section 131a is a generally rounded rectangular section extending from the opening side toward the slippage prevention section side. It is knitted using a plating knitting technique with a front yarn and a back yarn. In this plating knitting technique, a moisture-absorbing heat-generating yarn is used as the front yarn. The moisture-absorbing heat-generating yarn may be a yarn containing a moisture-absorbing heat-generating fiber. Examples of such yarns include acrylate fibers, wool, cotton, cupra, and rayon. Elastic or inelastic yarn may be used as the back yarn. When an elastic yarn is used as the back yarn, the medial acupoint stimulation section 131a serves as a tightening section. When the cold weather legwear 100 is worn on the leg, the medial acupoint stimulation section 131a is arranged to cover the Xuehai acupoint and the Yinlingquan acupoint, providing thermal stimulation to the Xuehai acupoint and the Yinlingquan acupoint. In addition, the medial acupoint stimulating section 131a may cover acupoints other than the Xuehai and Yinlingquan acupoints. The Xuehai acupoint Ak is located on the inside of the human knee, more specifically, about three fingers above the inner edge of the patella (kneecap), as shown in Figure 3. The Yinlingquan acupoint Ai is located directly below the thick bone on the inside of the knee, as shown in Figure 4.

[0044] (3-2) Outer Acupoint Stimulation Section As shown in FIG. 2, the outer acupoint stimulation section 131b is a generally rounded rectangular section extending from the opening side toward the slippage prevention section side. It is knitted using a plating knitting technique with a front yarn and a back yarn. In this plating knitting technique, a moisture-absorbing heat-generating yarn is used as the front yarn. The moisture-absorbing heat-generating yarn may be a yarn containing a moisture-absorbing heat-generating fiber. Examples of such yarns include acrylate fibers, wool, cotton, cupra, and rayon. Elastic or inelastic yarn may be used as the back yarn. When an elastic yarn is used as the back yarn, the outer acupoint stimulation section 131b serves as a tightening section. When the cold weather legwear 100 is worn on the leg, the outer acupoint stimulation section 131b is arranged to cover the Zhiyangguan and Zusanli acupoints, providing thermal stimulation to the Zhiyangguan and Zusanli acupoints. The lateral acupoint stimulation unit 131b may cover acupoints other than the Zhiyangguan acupoint and the Zusanli acupoint. The Zhiyangguan acupoint Ah is located at the height of the apex of the kneecap (kneecap), just behind the iliotibial band on the outside of the thigh, as shown in Figure 5. The Zusanli acupoint Aa is located outside the Zhiyangguan acupoint Ah, as shown in Figure 4.

[0045] (3-3) Front Shin Covering Section As shown in Figures 1 and 2, the front shin covering section 132a is a rectangular section extending from the opening side toward the slippage prevention section side. It is knitted using plating knitting with a front yarn and a back yarn. This front shin covering section 132a is formed on a different wale on the same course as the medial acupressure point stimulation section 131a and the lateral acupressure point stimulation section 131b. A low-heat-generating yarn is used as the front yarn in this plating knitting. The low-heat-generating yarn may have lower hygroscopic heat-generating properties than the hygroscopic heat-generating yarns used to knit the medial acupressure point stimulation section 131a and the lateral acupressure point stimulation section 131b, or may have no hygroscopic heat-generating properties at all. The low-heat-generating yarn may be a yarn containing a hygroscopic heat-generating fiber. Examples of such yarns include yarns containing acrylate fibers, wool, cotton, cupra, rayon, and the like. However, if the hygroscopic heat-generating yarn used to knit the medial acupoint stimulating portion 131a or the lateral acupoint stimulating portion 131b contains a hygroscopic heat-generating fiber, the content of the low heat-generating yarn must be lower than the content of the hygroscopic heat-generating fiber contained in the yarn. Furthermore, under this condition, the low heat-generating yarn may be made of the same material as the hygroscopic heat-generating yarn used to knit the medial acupoint stimulating portion 131a or the lateral acupoint stimulating portion 131b, containing the same hygroscopic heat-generating fiber. Furthermore, either elastic or non-elastic yarn may be used as the backing yarn. When elastic yarn is used as the backing yarn, the front shin covering portion 132a serves as the tightening portion. The front shin covering portion 132a is disposed between the front edge of the medial acupoint stimulating portion 131a and the front edge of the lateral acupoint stimulating portion 131b. The front shin covering portion 132a is arranged to cover the front part of the shin when the cold weather legwear 100 is worn on the leg.

[0046] (3-4) Rear Shin Covering Section As shown in Figures 1 and 2, the rear shin covering section 132b is a rectangular section extending from the opening side toward the slippage prevention section side. It is knitted using plating knitting with a front yarn and a back yarn. This rear shin covering section 132b is formed on a different wale on the same course as the medial acupressure point stimulation section 131a and the lateral acupressure point stimulation section 131b. A low-heat-generating yarn is used as the front yarn in this plating knitting. The low-heat-generating yarn may have lower hygroscopic heat-generating properties than the hygroscopic heat-generating yarns used to knit the medial acupressure point stimulation section 131a and the lateral acupressure point stimulation section 131b, or may have no hygroscopic heat-generating properties at all. The low-heat-generating yarn may be a yarn containing a hygroscopic heat-generating fiber. Examples of such yarns include yarns containing acrylate fibers, wool, cotton, cupra, rayon, and the like. However, if the hygroscopic heat-generating yarn used to knit the medial acupoint stimulating portion 131a or the lateral acupoint stimulating portion 131b contains a hygroscopic heat-generating fiber, the content of the low heat-generating yarn must be lower than the content of the hygroscopic heat-generating fiber contained in the yarn. Furthermore, under this condition, the low heat-generating yarn may be made of the same material as the hygroscopic heat-generating yarn used to knit the medial acupoint stimulating portion 131a or the lateral acupoint stimulating portion 131b, containing the same hygroscopic heat-generating fiber. Furthermore, either elastic or non-elastic yarn may be used as the backing yarn. When elastic yarn is used as the backing yarn, the rear shin covering portion 132b serves as the tightening portion. The rear shin covering portion 132b is disposed between the rear edge of the medial acupoint stimulating portion 131a and the rear edge of the lateral acupoint stimulating portion 131b. The rear shin covering portion 132b is arranged to cover the rear part of the shin when the cold weather legwear 100 is worn on the leg.

[0047] (3-5) Slippage prevention section Slippage prevention section 133 is, as the name suggests, a non-tightening section, and as shown in Figures 1 and 2, is located directly above clamping section 120 and directly below medial acupoint stimulation section 131a, lateral acupoint stimulation section 131b, anterior shin covering section 132a, and posterior shin covering section 132b, i.e., between clamping section 120 and medial acupoint stimulation section 131a, lateral acupoint stimulation section 131b, anterior shin covering section 132a, and posterior shin covering section 132b. The slippage suppression portion 133 is not particularly limited as long as it suppresses downward slippage of the partial leg covering portion 130 when the cold weather legwear is worn, but is preferably formed from (a) a knitted fabric knitted with a zokki knit, (b) a knitted fabric knitted with a front yarn that is more extensible than the front yarn that forms the acupoint stimulation portions 131a, 131b and the front yarn that forms the shin covering portions 132a, 132b, or (c) a knitted fabric knitted with a back yarn that is more extensible and less likely to shrink than the back yarn that forms the acupoint stimulation portions 131a, 131b and the back yarn that forms the shin covering portions 132a, 132b, using a plating knit. Note that when the slippage suppression portion 133 is knitted with a zokki knit, a low-heat-generating yarn is used as the front yarn of the zokki knit, and no back yarn is used. In this case, the extensibility of the slippage suppression section 133 is higher in the wale direction than the medial acupoint stimulation section 131a, the lateral acupoint stimulation section 131b, the anterior shin covering section 132a and the posterior shin covering section 132b.

[0048] (3-6) Above-Knee Covering Section The above-knee covering section 134 is formed of knitted fabric, and as shown in Figures 1 and 2, is disposed directly above the medial acupoint stimulating section 131a, the lateral acupoint stimulating section 131b, the front shin covering section 132a, and the rear shin covering section 132b, and directly below the opening 135, i.e., between the medial acupoint stimulating section 131a, the lateral acupoint stimulating section 131b, the front shin covering section 132a, and the rear shin covering section 132b, and the opening 135. As shown in Figures 1 and 2, it is preferable that the above-knee covering section 134 be knitted with multiple regions of different elasticity along the circumferential direction at regular intervals in the height direction. Note that the region indicated by the symbol 134a in Figures 1 and 2 is a plating knitted section of front yarn and back yarn, an elastic yarn insertion knitted section, a tuck knitted section with low elasticity, or a rib knitted section with strong contractile force. If the region designated by reference numeral 134a is a plating knitted section of front and back yarns, the front yarn is preferably more elastic and has a higher contractile force than the front yarns knitted in the medial acupoint stimulation section 131a, the lateral acupoint stimulation section 131b, the front shin covering section 132a, and the rear shin covering section 132b. This region 134a has a higher tightening force than the medial acupoint stimulation section 131a, the lateral acupoint stimulation section 131b, the front shin covering section 132a, and the rear shin covering section 132b. Region 134a may have a higher tightening force than at least one of the medial acupoint stimulation section 131a, the lateral acupoint stimulation section 131b, the front shin covering section 132a, and the rear shin covering section 132b. Meanwhile, the region designated by reference numeral 134b is a zokki knitted section with no back yarn or a knitted section without elastic yarn. This region 134b has higher wale-direction extensibility than the medial acupoint stimulation portion 131a, the lateral acupoint stimulation portion 131b, the anterior shin covering portion 132a, and the posterior shin covering portion 132b. Note that region 134b may be configured to have higher wale-direction extensibility than at least one of the medial acupoint stimulation portion 131a, the lateral acupoint stimulation portion 131b, the anterior shin covering portion 132a, and the posterior shin covering portion 132b. In other words, in this above-knee covering portion 134, regions that compress the area above the knee (i.e., region 134a) and regions that do not compress (i.e., region 134b) are alternately arranged.

[0049] (3-7) Opening The opening 135 is disposed above the above-knee covering part 134. This opening 135 is a normal opening and is knitted by conventional knitting techniques.

[0051] (2) Method of Knitting the Partial Leg Covering Portion As a method of forming the partial leg covering portion 130, for example, (i) knitting the opening portion 135 from the opening end of the opening portion 135 to the end of the opening portion 135 on the side of the above-knee covering portion, then switching the yarn and knitting the above-knee covering portion 134 from the end of the opening portion on the side of the above-knee covering portion to the end of the above-knee covering portion 134 on the side of the central covering portion, and then switching the yarn to knit the central covering portion (the inner acupoint stimulating portion 131a, the outer acupoint stimulating portion 131b, the front shin covering portion (ii) a method of knitting the inner knitted layer Li of the central covering part by knitting from the end of the central covering part on the above-knee covering part side to the end of the central covering part on the slippage-suppressing part side, and then switching yarn to knit from the end of the central covering part on the slippage-suppressing part side to the end of the central covering part on the above-knee covering part side, and then pushing the inner knitted layer Li of the central covering part into the outer knitted layer of the central covering part and connecting the inner knitted layer Li and the outer knitted layer at the end on the above-knee covering part side; or (iii) a method of knitting the inner knitted layer Li of the central covering part by knitting from the end of the central covering part on the above-knee covering part side to the end of the central covering part on the slippage-suppressing part side, and then switching yarn to knit from the end of the central covering part on the slippage-suppressing part side to the end of the central covering part on the above-knee covering part side, and then and knitting the above-knee covering part 134 from the end of the central covering part side of the above-knee covering part 134 to the end of the opening part side of the above-knee covering part 134, then switching yarns and knitting from the end of the opening part 135 on the above-knee covering part side to the end of the opening part of the opening part 135 to knit the opening part 135, and pushing the inner knitted layer Li of the central covering part into the outer knitted layer of the central covering part and connecting the inner knitted layer Li and the outer knitted layer at the end on the above-knee covering part side.

[0052] The inner knitted layer Li can be knitted in the same manner as before by switching yarns in the course direction in each of the areas of the inner acupoint stimulation section 131a, the outer acupoint stimulation section 131b, the front shin covering section 132a, and the rear shin covering section 132b.

[0053] The partial leg covering portion 130 and the slippage prevention portion 133 can be connected by a conventional method such as sewing.

[0054] <Features of the cold weather legwear according to the embodiment of the present invention> (1) In the cold weather legwear 100 according to the embodiment of the present invention, the inner knitted fabric layer Li of the partial leg-covering portion 130 is provided with an inner acupoint stimulating portion 131a, an outer acupoint stimulating portion 131b, an above-knee covering portion 134 on the opening side of the front shin covering portion 132a, and a rear shin covering portion 132b, and a slippage suppression portion 133 is provided on the opposite side of the opening side. Therefore, the cold weather legwear 100 has a high elongation rate in the vertical direction, i.e., in the axial direction of the partial leg-covering portion 130. Therefore, when the wearer moves their legs, such as walking, while wearing this cold weather legwear 100, the slippage suppression portion 133 and the above-knee covering portion 134 stretch, thereby preventing the tensile force from being transmitted to the medial acupoint stimulation portion 131a, the lateral acupoint stimulation portion 131b, the anterior shin covering portion 132a, and the posterior shin covering portion 132b, thereby preventing the medial acupoint stimulation portion 131a and the lateral acupoint stimulation portion 131b from slipping off the leg. Therefore, this cold weather legwear 100 easily continues to stimulate the Xuehai acupoint Ak, the Yinlingquan acupoint Ai, the Zhiyangguan acupoint Ah, and the Zusanli acupoint Aa even when wearing it and walking, etc.

[0055] (2) In the cold weather legwear 100 according to the embodiment of the present invention, moisture-absorbing and heat-generating yarn is used in the inner acupoint stimulating portion 131a and the outer acupoint stimulating portion 131b of the inner knitted fabric layer Li of the partial leg covering portion 130, and low-heat-generating yarn is used in the front shin covering portion 132a and the back shin covering portion 132b. Therefore, in this cold weather legwear 100, it is possible to efficiently thermally stimulate only the acupoint Ak at the Xuehai acupoint, Ai at the Yinlingquan acupoint, Ah at the Zhiyangguan acupoint, and Aa at the Zusanli acupoint, and the areas around these acupoints.

[0056] (3) In the cold weather legwear 100 according to the embodiment of the present invention, the inner acupoint stimulating portion 131a, the outer acupoint stimulating portion 131b, the front shin covering portion 132a, and the rear shin covering portion 132b can be knitted by switching yarns. Therefore, in this cold weather legwear 100, the inner acupoint stimulating portion 131a and the outer acupoint stimulating portion 131b can be knitted using a conventional knitting method.

[0057] (4) In the cold weather legwear 100 according to the embodiment of the present invention, the outer knitted fabric layer of the partial leg covering portion 130 is knitted into a rib knitted fabric using pile sinker knitting with skipped elastic yarns. This improves the heat retention of the partial leg covering portion 130.

[0058] (5) In the cold weather legwear 100 according to the embodiment of the present invention, the acupoint stimulating portion is provided in two areas: one for stimulating the acupoints on the inside of the leg (i.e., the Xuehai acupoint and the Yinlingquan acupoint) and the other for stimulating the acupoints on the outside of the leg (i.e., the Zhiyangguan acupoint and the Zusanli acupoint). Therefore, the width of the acupoint stimulating portion in the course direction can be shortened in the cold weather legwear 100. Therefore, the cold weather legwear 100 can reduce the effort required for knitting the acupoint stimulating portion, and can efficiently thermally stimulate the acupoints and their surroundings while minimizing thermal stimulation of areas other than the acupoints and their surroundings.

[0059] (6) In the cold weather legwear 100 according to the embodiment of the present invention, two acupoints on the legs can be stimulated by each of the inner acupoint stimulating portion 131a and the outer acupoint stimulating portion 131b, and the acupoints on the legs around the knees can be stimulated efficiently.

[0060] (7) In the cold weather legwear 100 according to the embodiment of the present invention, elastic yarns are inserted in the circumferential direction at regular intervals in the height direction in the knitted fabric forming the above-knee covering portion 134.
