Description

[Technical Field]

[0001] The present invention relates to a garment for the lower legs. [Background technology]

[0002] Conventionally, garments for the lower legs (e.g., Patent Document 1) have been used that have a graduated compression design in which the pressure on the skin gradually decreases as one moves upward from the ankle to the calf and thigh, compressing the muscles and pushing blood upward to reduce fatigue and swelling in the lower legs. As disclosed in Patent Document 1, such garments for the lower legs are generally formed by sewing together a pair of leg sections formed into a tubular shape by circular knitting. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2011-115571 Summary of the Invention [Problem to be solved by the invention]

[0004] However, with the circular knitting method described above, leg sections must be made one by one, and a large number of circular knitting machines are required to mass-produce lower leg garments. To solve this problem, a method of producing lower leg garments by sewing together multiple parts cut from a large piece of fabric has been considered. With this method, multiple parts having a predetermined shape can be obtained in large numbers from a large piece of fabric. Therefore, by producing larger pieces of fabric using a larger knitting machine, more parts can be produced, and lower leg garments can be mass-produced. However, when lower leg garments are made from multiple parts, it is difficult to design the lower leg garments to have graduated compression.

[0005] The present invention has been made in consideration of the above-mentioned problems, and aims to provide a garment for lower legs that is formed by sewing together a plurality of parts and has a graduated compression design. [Means for solving the problem]

[0006] The lower limb garment of the present invention is a lower limb garment having leg sections designed so that the pressure applied to the leg sections decreases in stages in the order of the ankle, calf, and thigh, and is characterized in that the lower limb garment has a front body and a back body cut from stretchable fabric and sewn together, and the width of the back body is wider than the width of the front body.

[0007] It is also preferable that the width of the back body is 1.1 to 1.4 times the width of the front body.

[0008] It is also preferable that the width of the front body and the back body be approximately constant over a predetermined length including the portion corresponding to the hem of each of the front body and the back body to the portion corresponding to the ankle.

[0009] It is also preferable that the pressure applied to the ankle areas is 13 to 30 hPa, the pressure applied to the calves is 8 to 25 hPa, and the pressure applied to the thighs is 4 to 21 hPa.

[0010] It is also preferable that the stitching is flat seam stitching. [Effects of the Invention]

[0011] According to the present invention, it is possible to provide a garment for lower legs that is formed by sewing together a plurality of parts and has a graduated compression design. [Brief explanation of the drawings]

[0013] Hereinafter, a description will be given of a lower leg garment according to one embodiment of the present invention with reference to the accompanying drawings. However, the following embodiment is merely an example, and the lower leg garment of the present invention is not limited to the following example. In this specification, the term "upper" means the upper side of the human body in the height direction, and the term "lower" means the lower side of the human body in the height direction. Furthermore, the term "left" means the left side as seen from the human body, and the term "right" means the right side as seen from the human body. Furthermore, the term "front" means the front side of the human body, and the term "rear" means the rear side of the human body.

[0014] As shown in Fig. 1, the lower leg garment 1 of this embodiment is a garment that includes leg portions 2, 2 and is worn on the lower legs of a human body. In this embodiment, the lower leg garment 1 includes, in addition to the leg portions 2, 2, a shorts portion 3 that is formed continuously with the leg portions 2, 2. However, the lower leg garment of the present invention does not have to include the shorts portion 3, and may instead include, for example, only a leg portion for one leg. The lower leg garment 1 is not particularly limited and may be embodied as, for example, stockings, pantyhose, tights, spats, leggings, stirrup boots, etc.

[0015] As shown in Fig. 1, the leg portions 2, 2 include ankle portions 21, 21, calf portions 22, 22, and thigh portions 23, 23, and are portions that cover substantially the entire crotch area of ​​a human leg from the ankle to the thigh in the longitudinal direction L. The leg portions 2, 2 are designed so that when the lower leg garment 1 is worn on the human leg, the pressure applied to the skin of the human body decreases in stages in the order of the ankle portions 21, 21, the calf portions 22, 22, and the thigh portions 23, 23. As a result, when the lower leg garment 1 is worn on the human leg, it compresses the muscles and pushes blood upward, thereby reducing fatigue and swelling in the lower leg. The leg portions 2, 2 may be designed so that the pressure decreases in stages in the order of ankle portions 21, 21, calf portions 22, 22, and thigh portions 23, 23, and although there are no particular limitations, it is preferable that the pressure at the ankle portions 21, 21 is 13 to 30 hPa, the pressure at the calf portions 22, 22 is 8 to 25 hPa, and the pressure at the thigh portions 23, 23 is 4 to 21 hPa. In this embodiment, the leg portions 2, 2 are configured to cover substantially the entire crotch area of ​​the human body's lower limbs from the ankles to the thighs in the longitudinal direction L, but may also be configured to cover other areas, for example, down to the toes.

[0016] The shorts portion 3 covers the lower abdomen, waist, and buttocks of the human body. As shown in FIG. 1 , the shorts portion 3 is not sewn to the leg portions 2, 2 but is formed integrally with the upper portions of the leg portions 2, 2. The shorts portion 3 has one opening at the top that is positioned at the waist of the human body and two openings at the bottom that communicate with the leg portions 2, 2. At the top end of the shorts portion 3, the fabric forming the shorts portion 3 is folded in the vertical direction and the ends are sewn together to form a waist belt 31 with a fixing string 31a inserted therein. The waist belt 31 tightens the shorts portion 3 around the waist of the human body, preventing it from slipping down from the waist.

[0017] As shown in FIGS. 1 to 3 , the lower leg garment 1 includes front body sections 11, 12 and back body sections 13, 14, which are cut from stretchable fabric and sewn together. The front body sections 11, 12 and back body sections 13, 14 are each cut to a predetermined shape from stretchable fabric and are parts that constitute part of the lower leg garment 1. In this embodiment, the front body sections 11, 12 include a left front body section 11 and a right front body section 12, and the back body sections 13, 14 include a left back body section 13 and a right back body section 14, corresponding to the pair of leg sections 2, 2. The lower leg garment 1 may optionally include a crotch gusset 15. In this embodiment, the lower leg garment 1 is composed of five parts: the left front body section 11 and the right front body section 12, the left back body section 13 and the right back body section 14, and the crotch gusset 15.

[0018] The stretchable fabric that makes up the front body sections 11, 12, back body sections 13, 14, and crotch gusset 15 is not particularly limited as long as it is a stretchable fabric. For example, stretchable knit fabrics knitted with elastic or non-elastic yarns can be used as the stretchable fabric. Examples of elastic or non-elastic yarns include cotton yarn, polyester yarn, nylon yarn, and polyurethane yarn. Examples of knitting methods include bare jersey knitting, punch knitting, smooth knitting, rib knitting, pique knitting, tricot knitting, and Russell knitting.

[0019] The front body sections 11, 12, back body sections 13, 14, and crotch gusset 15 may be made of the same type of stretchable fabric, or different types of stretchable fabric. In this embodiment, the front body sections 11, 12, back body sections 13, 14, and crotch gusset 15 are made of the same type of stretchable fabric. By making the front body sections 11, 12, back body sections 13, 14, and crotch gusset 15 all from the same stretchable fabric, the lower leg garment 1 can be manufactured inexpensively and efficiently.

[0020] The front body sections 11, 12 are parts that are positioned mainly in front of the lower legs of a person when the lower leg garment 1 is worn on the lower legs of the person. In this embodiment, the front body sections 11, 12 are formed to extend in the longitudinal direction L from the ankles to the waist of the person, as shown in Figs. 1 and 2 . However, if the lower leg garment 1 does not include a shorts section 3, the front body sections 11, 12 are formed to extend in the longitudinal direction L of the crotch area from the ankles to the thighs of the person. In this embodiment, as described above, the front body sections 11, 12 include a left front body section 11 and a right front body section 12, with the left front body section 11 being positioned mainly in front of the lower leg on the left side of the person, and the right front body section 12 being positioned mainly in front of the lower leg on the right side of the person.

[0021] The back body parts 13, 14 are parts that are positioned mainly behind the lower legs of a person when the lower leg garment 1 is worn on the person's lower legs. In this embodiment, the back body parts 13, 14 are formed to extend in the longitudinal direction L from the ankles to the waist, as shown in Figs. 1 and 3. However, if the lower leg garment 1 does not include a shorts section 3, the back body parts 13, 14 are formed to extend in the longitudinal direction L of the crotch from the ankles to the thighs. In this embodiment, as described above, the back body parts 13, 14 include a left back body part 13 and a right back body part 14, with the left back body part 13 being positioned mainly behind the left lower leg of the person's body, and the right back body part 14 being positioned mainly behind the right lower leg of the person's body.

[0022] The crotch gusset 15 is a part that is positioned mainly between the legs of the human body when the lower leg garment 1 is worn on the human body's lower legs. As shown in Figures 1 and 4, the crotch gusset 15 is formed in a generally oval shape extending in a width direction W that is perpendicular to the longitudinal direction L, and is positioned by being folded approximately at the center in the width direction W. The crotch gusset 15 is positioned between the left front body 11, the right front body 12, the left back body 13, and the right back body 14 so that it is surrounded by the left front body 11, the right front body 12, the left back body 13, and the right back body 14.

[0023] As shown in Fig. 1, the front body sections 11, 12 and the back body sections 13, 14 are formed into a tubular shape by sewing together their edges in the width direction (circumferential direction) W along the longitudinal direction L to form the leg sections 2, 2. More specifically, the left leg section 2 is formed by sewing together both edges in the width direction W of the left front body section 11 and the left back body section 13 along the longitudinal direction L to form a tubular shape, and the right leg section 2 is formed by sewing together both edges in the width direction W of the right front body section 12 and the right back body section 14 along the longitudinal direction L to form a tubular shape. In this embodiment, the shorts section 3 is formed by sewing together the edges of the front body sections 11, 12, the back body sections 13, 14, and the crotch gusset 15.

[0024] The stitching between the front body sections 11, 12 and the back body sections 13, 14 (and the crotch gusset 15) is not particularly limited, and can be performed by any known stitching method, as long as it is strong enough to prevent the front body sections 11, 12 and the back body sections 13, 14 (and the crotch gusset 15) from being cut apart at the stitching line 16 even when the human body moves while the lower leg garment 1 is worn on the lower leg. In this embodiment, the stitching between the front body sections 11, 12 and the back body sections 13, 14 (and the crotch gusset 15) is performed by flat seam stitching. By using flat seam stitching to stitch each part together, the difference in level between each part is reduced, improving the fit against the human skin.

[0025] As shown in FIGS. 1 to 3, the front body sections 11, 12 and the back body sections 13, 14 are formed so that the width of the back body sections 13, 14 is wider than the width of the front body sections 11, 12. By making the width of the back body sections 13, 14 wider than the width of the front body sections 11, 12, it is possible to easily create a graduated compression design for the lower leg garment 1. This is thought to be because the back of the lower leg bulges more than the front due to, for example, the gastrocnemius muscle in the calf and the biceps femoris muscle in the thigh. By forming the parts wider to accommodate this bulge, the leg sections 2, 2 can more easily deform to conform to the shape of the lower leg and more easily compress the lower leg. In particular, the seam line 16 between the front body sections 11, 12 and the back body sections 13, 14 has reduced elasticity, making it less likely to deform to conform to the shape of the lower leg. In this embodiment, the width of the back body parts 13, 14 is wider than the width of the front body parts 11, 12, so that all of the sewing lines 16 between the front body parts 11, 12 and the back body parts 13, 14 are positioned in front of the leg parts 2, 2 (see FIG. 1(a)). This is thought to increase the degree of freedom of deformation of the rear of the leg parts 2, 2, making it easier to compress the lower legs. The front body parts 11, 12 and the back body parts 13, 14 may be formed so that the width of the back body parts 13, 14 is wider than the width of the front body parts 11, 12, and are not particularly limited, but it is preferable that the width of the back body parts 13, 14 is 1.1 to 1.4 times the width of the front body parts 11, 12. Furthermore, the width of the back body parts 13, 14 is not particularly limited as long as it is wider than the width of the front body parts 11, 12 at least in part, but it is preferable that it is wider than the width of the front body parts 11, 12 over the entire length in the longitudinal direction L.

[0026] More specifically, in this embodiment, as described above, the front bodice portions 11, 12 include a left front bodice portion 11 and a right front bodice portion 12, and the back bodice portions 13, 14 include a left back bodice portion 13 and a right back bodice portion 14. The width of the portions of the left back bodice portion 13 and the right back bodice portion 14 corresponding to the leg portions 2, 2 is wider than the width of the portions of the left front bodice portion 11 and the right front bodice portion 12 corresponding to the leg portions 2, 2. This allows for a graduated compression design to be easily achieved in both of the pair of leg portions 2, 2. The width of the portions of the left back bodice portion 13 and the right back bodice portion 14 corresponding to the leg portions 2, 2 need only be wider than the width of the portions of the left front bodice portion 11 and the right front bodice portion 12 corresponding to the leg portions 2, 2, and is not particularly limited, but is preferably 1.1 to 1.4 times the width of the portions of the left front bodice portion 11 and the right front bodice portion 12 corresponding to the leg portions 2, 2. Furthermore, the width of the portions of the left back bodice 13 and right back bodice 14 corresponding to the leg portions 2, 2 may be at least partially wider than the width of the portions of the left front bodice 11 and right front bodice 12 corresponding to the leg portions 2, 2, and is not particularly limited, but it is preferable that the width be wider than the width of the portions of the left front bodice 11 and right front bodice 12 corresponding to the leg portions 2, 2 over the entire length of the longitudinal direction L of the leg portions 2, 2.

[0027] Furthermore, the width of the portions of the left back body 13 and right back body 14 corresponding to the shorts section 3 is also wider than the width of the portions of the left front body 11 and right front body 12 corresponding to the shorts section 3. This makes the parts wider to accommodate the buttocks of the human body covered by the shorts section 3, making it easier to deform according to the swelling of the buttocks, and allowing the shorts section 3 to fit the human body. The width of the portions of the left back body 13 and right back body 14 corresponding to the shorts section 3 should be wider than the width of the portions of the left front body 11 and right front body 12 corresponding to the shorts section 3, and is not particularly limited, but is preferably 1.1 to 1.4 times the width of the portions of the left front body 11 and right front body 12 corresponding to the shorts section 3. Furthermore, the width of the portions of the left back body 13 and the right back body 14 corresponding to the shorts portion 3 need only be wider, at least in part, than the width of the portions of the left front body 11 and the right front body 12 corresponding to the shorts portion 3, and is not particularly limited, but it is preferable that the width be wider than the width of the portions of the left front body 11 and the right front body 12 corresponding to the shorts portion 3 over the entire length in the longitudinal direction L of the shorts portion 3.

[0028] The widths of the front body sections 11, 12 and the back body sections 13, 14 can be appropriately set so that at least the width of the back body sections 13, 14 is wider than the width of the front body sections 11, 12, and so that the leg sections 2, 2 have the above-mentioned graduated compression design. In this embodiment, as shown in Figures 2 and 3, the front body sections 11, 12 and the back body sections 13, 14 have a substantially constant width over a predetermined length L1 that extends from the portion corresponding to the hem section 24 of each of the front body sections 11, 12 and the back body sections 13, 14 to the portion corresponding to the ankle section 21. As a result, the leg sections 2, 2 have a substantially constant inner diameter over the predetermined length L1 that extends from the hem section 24 to the ankle section 21, and can apply a substantially constant pressure to the ankle of the human body along the longitudinal direction L. The predetermined length L1, which includes the part corresponding to the hem 24 and the part corresponding to the ankle 21, may be the length of the region below the part corresponding to the calf 22, excluding at least the part corresponding to the calf 22. More specifically, the predetermined length L1 may be set, for example, in the range of 4 to 8 cm, and preferably in the range of 5 to 7 cm. [Explanation of symbols]
