Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in wearing devices such as the above-mentioned socks, the tightening force of the tightening portion above the covering portion that covers any of the heel, knee, and elbow prevents displacement and slipping during movements such as walking and exercising when worn. On the other hand, if the tightening force is too strong, it may lead to a decrease in the wearing comfort, such as marks remaining on the skin after wearing and discomfort due to tightening. Therefore, in recent years, there has been a demand for a wearing device that can prevent displacement and slipping during movements such as walking and exercising when worn and has a good wearing comfort without excessive tightening.

[0005] An object of the present invention is to provide a wearing device that can prevent displacement and slipping during movements such as walking and exercising when worn and has a good wearing comfort without excessive tightening.

Means for Solving the Problems

[0006] A fitting device according to the first aspect of the present invention comprises a covering portion, a first cylindrical portion, and a second cylindrical portion. The covering portion covers either the heel, knee, or elbow when worn. The first cylindrical portion extends from the first end of the covering portion toward the first side and has a cylindrical shape. The second cylindrical portion extends from the second end of the covering portion toward the second side, which is different from the first side, and has a cylindrical shape, and is continuous with the first cylindrical portion via the covering portion. The first cylindrical portion also has a first circumferential portion and a first low-stretch portion. The first circumferential portion is provided around the first cylindrical portion and is knitted from a first face yarn and a first back yarn having a higher coefficient of friction than the first face yarn. "Provided around" means formed along the circumferential direction of a certain portion, and may be formed to be an annular shape without any gaps, or may be formed to be an annular shape with one or more gaps. The first low-stretch portion is knitted within the first circumferential portion and has less stretch than the first circumferential portion.

[0007] According to the above configuration, when the device is a sneaker sock (registered trademark), foot cover, or other footwear that has a height that covers up to the ankle, that is, footwear that does not have a part that covers the part above the ankle (hereinafter referred to as "ankle-length footwear"), when worn, the covering part covers the heel, the first tube part covers the ankle, and the second tube part covers the top and bottom of the foot. When worn, the first low-stretch part of the first tube part tightens the ankle, and the first backing thread with a relatively high coefficient of friction of the first circumferential part of the first tube part makes it difficult for the first tube part to slip against the ankle. Also, when the device is a knee support, when worn, the covering part covers the knee, the first tube part covers above the knee, and the second tube part covers below the knee. When worn, the first low-stretch part of the first tube part tightens above the knee, and the first backing thread with a relatively high coefficient of friction of the first circumferential part of the first tube part makes it difficult for the first tube part to slip against the knee. Furthermore, if the device is an elbow support, when worn, the covering portion covers the elbow, the first cylindrical portion covers the upper part of the elbow, and the second cylindrical portion covers the lower part of the elbow. When worn, the first low-stretch portion of the first cylindrical portion tightens the upper part of the elbow, and the first backing thread, which has a relatively high coefficient of friction in the first circumferential portion of the first cylindrical portion, makes the first cylindrical portion less likely to slip against the upper part of the elbow. Here, the tightening force of the first low-stretch portion of the first cylindrical portion can be weaker than the tightening force of the tightening portion in conventional devices. Therefore, this device can prevent slippage and coming off during walking, exercise, and other movements while being worn, and it can also improve the wearing comfort without being too tight.

[0008] The attachment device according to the second aspect of the present invention is the attachment device according to the first aspect, wherein the inner side of the first circumferential portion has a higher coefficient of friction than the inner side of the covering portion. Furthermore, the first low-stretch portion has less stretch than the covering portion.

[0009] The above configuration further prevents slippage and falling off during walking, exercise, and other movements while wearing the device.

[0010] The attachment device according to the third aspect of the present invention is the attachment device according to the second aspect, wherein the first low-stretch portion is formed by inserting a boss thread.

[0011] The boss thread is preferably a highly elastic and flexible thread, such as woolly nylon. With the above configuration, slippage and coming off during walking, exercise, and other movements while wearing the garment can be further prevented.

[0012] The attachment according to the fourth aspect of the present invention is an attachment according to any one of the first to third aspects, wherein the second tubular portion has a second circumferential portion and a second low-stretch portion. The second circumferential portion is provided around the second tubular portion and is knitted from a second face yarn and a second back yarn having a higher coefficient of friction than the second face yarn. The second low-stretch portion is knitted within the second circumferential portion and is less stretchable than the second circumferential portion.

[0013] According to the above configuration, when the device is ankle-length footwear, the second low-stretch portion of the second tube tightens the second tube on the instep and sole of the foot when worn, and the second backing thread with a relatively high coefficient of friction of the second circumferential portion of the second tube makes the second tube less likely to slip against the instep and sole of the foot. Furthermore, when the device is a knee support, the second low-stretch portion of the second tube tightens the second tube below the knee when worn, and the second backing thread with a relatively high coefficient of friction of the second circumferential portion of the second tube makes the second tube less likely to slip against the lower leg. Furthermore, when the device is an elbow support, the second low-stretch portion of the second tube tightens the second tube below the elbow when worn, and the second backing thread with a relatively high coefficient of friction of the second circumferential portion of the second tube makes the second tube less likely to slip against the lower leg. Furthermore, the tightening force of the second low-stretch portion of the second tube can be made weaker than the tightening force of the tightening portion in conventional fasteners. Therefore, this fastener can further prevent slippage and coming off during walking, exercise, and other movements while being worn, and it can also improve the wearing comfort without being too tight.

[0014] The attachment device according to the fifth aspect of the present invention is an attachment device according to the fourth aspect, wherein the inner side of the second circumferential portion has a higher coefficient of friction than the inner side of the covering portion. Furthermore, the second low-stretch portion has less stretch than the covering portion.

[0015] The above configuration further prevents slippage and falling off during walking, exercise, and other movements while wearing the device.

[0016] The attachment device according to the sixth aspect of the present invention is the attachment device according to the fifth aspect, wherein the second low-stretch portion is formed by inserting a boss thread.

[0017] The boss thread is preferably a highly elastic and flexible thread, such as woolly nylon. With the above configuration, slippage and coming off during walking, exercise, and other movements while wearing the garment can be further prevented.

[0018] The seventh aspect of the present invention is a fitting device relating to the first or second aspect, further comprising a pass-through portion. The pass-through portion is formed on the side of the first cylindrical portion opposite to the second cylindrical portion and is knitted from a third surface yarn having a higher coefficient of friction than the first surface yarn.

[0019] According to the above configuration, when the device is ankle-length footwear, the third outer thread, which has a relatively high coefficient of friction at the opening, prevents the opening from slipping against the ankle (more specifically, the upper part of the ankle covered by the first tube) when worn. Similarly, when the device is a knee support, the third outer thread, which has a relatively high coefficient of friction at the opening, prevents the opening from slipping against the upper part of the knee (more specifically, the upper part of the upper part of the knee covered by the first tube) when worn. Furthermore, when the device is an elbow support, the third outer thread, which has a relatively high coefficient of friction at the opening, prevents the opening from slipping against the upper part of the elbow (more specifically, the upper part of the upper part of the elbow covered by the first tube) when worn. Therefore, this device can further prevent slippage and coming off during walking, exercise, and other movements while being worn. [Brief explanation of the drawing]

[Figure 3] It is a side view of the knee supporter according to the second embodiment of the present invention.

Embodiments for Carrying out the Invention

[0021] <Configuration of the Wearable Device According to the Embodiment of the Present Invention> The wearable device according to the embodiment of the present invention is a wearable device that is at least worn on the foot or arm, and examples thereof include ankle-length footwear, knee supporters, elbow supporters, and the like.

[0022] -First Embodiment- As an example of the wearable device according to the first embodiment of the present invention, ankle-length footwear 1 shown in FIG. 1 can be cited. Hereinafter, this ankle-length footwear 1 will be described in detail.

[0023] The ankle-length footwear 1 according to the first embodiment of the present invention呈鉤状 in a side view as shown in FIG. 1, and is mainly formed from a toe covering portion 100, a foot covering portion 110, a heel covering portion 120, an ankle covering portion 130, a mouth portion 140, and the like. Hereinafter, these parts will be described in detail.

[0024] For the sake of convenience of explanation, the vertical direction and the front-rear direction are defined in FIG. 1. Hereinafter, the ankle-length footwear 1 may be described using these directions.

[0025] (1) Toe covering portion The toe covering portion 100 is a bag-shaped part for covering the toes, and as shown in FIG. 1, it extends forward from the front end of the foot covering portion 110. Further, the toe covering portion 100 is knitted from a highly stretchable knitted fabric. The highly stretchable knitted fabric can be knitted from, for example, natural yarns such as cotton, hemp, wool, and silk, or synthetic yarns such as nylon and polyester, or blended yarns thereof.

[0026] (2) Foot covering portion The foot covering portion 110 is a cylindrical portion for covering the top and bottom sides of the foot, and as shown in Figure 1, it extends posteriorly from the rear end of the toe covering portion 100 (and forward from the front end of the heel covering portion 120), and is continuous with the ankle covering portion 130 via the heel covering portion 120.

[0027] Furthermore, as shown in Figures 1 and 2, the foot covering portion 110 has a front circumferential portion 111 and a front low-stretch portion 112 formed thereon. The portion of the foot covering portion 110 that does not have the front circumferential portion 111 and the front low-stretch portion 112 formed thereon is knitted with a highly elastic fabric (as described above). The front circumferential portion 111 is provided around the foot covering portion 110 as shown in Figures 1 and 2. The front circumferential portion 111 may be provided around the foot covering portion 110 in the form of a ring without any gaps, or it may be provided around the foot covering portion 110 in the form of a ring with one or more gaps. Also, as shown in Figures 1 and 2, the upper part of the front circumferential portion 111 is connected to the front part of the upper circumferential portion 131 of the ankle covering portion 130. The front circumferential portion 111 is knitted from face yarn and back yarn. The face yarn is, for example, a natural yarn such as cotton, linen, wool, or silk, or a synthetic yarn such as nylon or polyester, or a blend of these. The back yarn is a yarn with a higher coefficient of friction than the face yarn, and is, for example, a split fiber yarn, polyurethane, Nanofront®, or Clinpal®. As a result, the inside (skin side) of the front perimeter portion 111 has a higher coefficient of friction than the inside (skin side) of the heel covering portion 120. The front low-stretch portion 112 is knitted within the front perimeter portion 111 (inner region), as shown in Figures 1 and 2. The front low-stretch portion 112 may be knitted closer to the center of the front perimeter portion 111 (see Figures 1 and 2), closer to the front of the front perimeter portion 111, or closer to the rear of the front perimeter portion 111. Furthermore, as shown in Figures 1 and 2, the front low-stretch portion 112 is arranged within the front circumferential portion 111 in a ring shape with a section missing on the instep side of the foot. However, it may also be arranged within the front circumferential portion 111 in a ring shape with one or more sections missing in addition to the section missing on the instep side of the foot. In other words, the front low-stretch portion 112 may be arranged in various shapes and forms as long as it is incorporated within the front circumferential portion 111. Also, as shown in Figures 1 and 2, the upper end of the front low-stretch portion 112 (i.e., the end on which the section missing on the instep side of the foot is formed) is connected to the front end of the upper low-stretch portion 132 of the ankle covering portion 130 (i.e., the end on which the section missing on the front side of the ankle is formed).The front low-stretch portion 112 is formed so as to suppress elongation by inserting boss yarn into the face yarn or back yarn, resulting in lower stretch than the front circumferential portion 111 and the heel covering portion 120. The face yarn is, for example, a natural yarn such as cotton, linen, wool, or silk, or a synthetic yarn such as nylon or polyester, or a blend of these. The back yarn is a yarn with a higher coefficient of friction than the face yarn, such as split fiber yarn, polyurethane, Nanofront®, or Clinpal®. The boss yarn is a yarn with high elasticity and flexibility, and it is preferable to use, for example, woolly nylon. As an alternative knitting method, the front low-stretch portion 112 may also be made to have lower stretch than the front circumferential portion 111 and the heel covering portion 120 by knitting with tuck knitting, reducing the gauge, inserting elastic yarn, or a combination of these methods. Furthermore, when inserting the boss thread, it is preferable to have the boss thread pass through the inside of the front low-stretch portion 112, i.e., the skin side, and the length of the boss thread passing through the skin side is preferably such that the fingers do not get caught on the boss thread when wearing the garment. The length of the boss thread is adjusted appropriately according to the wearer's age, gender, physique, etc. If the boss thread is not cut where it passes through the skin side, stretching is further suppressed, and slippage and coming off during walking, exercise, etc., can be effectively prevented. If the boss thread is cut where it passes through the skin side, the elasticity is appropriately maintained, resulting in a comfortable fit with just the right amount of tightness, and slippage and coming off during walking, exercise, etc., can be prevented. Also, if the length of the boss thread is longer than the width of the fingers, cutting the boss thread where it passes through can prevent the fingers from getting caught on it. In addition, tightening the weave around the boss thread suppresses stretching, effectively preventing slippage and coming off during walking, exercise, etc., and can also prevent the boss thread from falling out.

[0028] (3) Heel covering The heel covering portion 120 is a part that covers the heel and extends (bulges) from the rear end of the foot covering portion 110 as shown in Figure 1, and is made of a highly elastic knitted fabric (as described above). Also, as described above, the inner side (skin side) of the heel covering portion 120 has a lower coefficient of friction than the inner side (skin side) of the front periphery portion 111, and the heel covering portion 120 has higher elasticity than the front low-elasticity portion 112. Furthermore, as will be described later, the inner side (skin side) of the heel covering portion 120 has a lower coefficient of friction than the inner side (skin side) of the upper periphery portion 131, and the heel covering portion 120 has higher elasticity than the upper low-elasticity portion 132.

[0029] (4) Ankle covering The ankle covering portion 130 is a cylindrical portion for covering the ankle, and as shown in Figure 1, it extends upward from the upper end of the heel covering portion 120 and is continuous with the foot covering portion 110 via the heel covering portion 120.

[0030] Furthermore, as shown in Figures 1 and 2, the ankle covering portion 130 has an upper circumferential portion 131 and an upper low-stretch portion 132 formed thereon, and the portion of the ankle covering portion 130 that does not have the upper circumferential portion 131 and the upper low-stretch portion 132 formed thereon is knitted with a highly elastic knit fabric (as described above). The upper circumferential portion 131 is provided around the ankle covering portion 130 as shown in Figures 1 and 2. The upper circumferential portion 131 may be provided around the ankle covering portion 130 to form a ring without any gaps, or it may be provided around the ankle covering portion 130 to form a ring with one or more gaps. As described above, the front part of the upper circumferential portion 131 is connected to the upper part of the front circumferential portion 111 of the ankle covering portion 110. The upper circumferential portion 131 is knitted from face yarn and back yarn. The face yarn is, for example, a natural yarn such as cotton, linen, wool, or silk, or a synthetic yarn such as nylon or polyester, or a blend of these. The back yarn is a yarn with a higher coefficient of friction than the face yarn, and is, for example, a split fiber yarn, polyurethane, Nanofront®, or Clinpal®. As a result, the inside (skin side) of the upper circumferential portion 131 has a higher coefficient of friction than the inside (skin side) of the heel covering portion 120. The upper low-stretch portion 132 is knitted within the upper circumferential portion 131 (inner region), as shown in Figures 1 and 2. The upper low-stretch portion 132 may be knitted closer to the center of the upper circumferential portion 131 (see Figures 1 and 2), closer to the top of the upper circumferential portion 131, or closer to the bottom of the upper circumferential portion 131. Furthermore, as shown in Figures 1 and 2, the upper low-stretch portion 132 is arranged within the upper circumferential portion 131 to form a ring with a gap at the front of the ankle. However, it may also be arranged within the upper circumferential portion 131 to form a ring with one or more gaps in addition to the gap at the front of the ankle. In other words, the upper low-stretch portion 132 may be arranged in various shapes and forms as long as it is incorporated within the upper circumferential portion 131. Also, as described above, the front end of the upper low-stretch portion 132 (i.e., the end on which the gap at the front of the ankle is formed) is connected to the upper end of the front low-stretch portion 112 of the foot covering portion 110 (i.e., the end on which the gap on the top of the foot is formed).The upper low-stretch portion 132 is formed so as to suppress elongation by inserting boss yarn into the face yarn or back yarn, resulting in lower stretch than the upper circumferential portion 131 and the heel covering portion 120. The face yarn is, for example, a natural yarn such as cotton, linen, wool, or silk, or a synthetic yarn such as nylon or polyester, or a blend of these. The back yarn is a yarn with a higher coefficient of friction than the face yarn, such as split fiber yarn, polyurethane, Nanofront®, or Clinpal®. The boss yarn is a yarn with high elasticity and flexibility, and it is preferable to use, for example, woolly nylon. As an alternative knitting method, the upper low-stretch portion 132 may also be made to have lower stretch than the upper circumferential portion 131 and the heel covering portion 120 by knitting with tuck knitting, reducing the gauge, inserting elastic yarn, or a combination of these methods. Furthermore, when inserting the boss thread, it is preferable to have the boss thread cross the inside of the upper peripheral portion 131, i.e., the skin side, and the length of the boss thread crossing the skin side is preferably such that the fingers do not get caught on the boss thread when wearing the garment. The length of the boss thread is adjusted appropriately according to the wearer's age, gender, physique, etc. If the boss thread is not cut where it crosses the skin side, stretching is further suppressed, and slippage and coming off during walking, exercise, etc., can be effectively prevented. If the boss thread is cut where it crosses the skin side, elasticity is appropriately maintained, resulting in a comfortable fit with just the right amount of tightness, and slippage and coming off during walking, exercise, etc., can be prevented. Also, if the length of the boss thread is longer than the width of the fingers, cutting the boss thread where it crosses the skin can prevent the fingers from getting caught on it. In addition, tightening the weave around the boss thread suppresses stretching, effectively preventing slippage and coming off during walking, exercise, etc., and can also prevent the boss thread from falling out.

[0031] By the way, in conventional designs where slippage and slippage during walking and exercise are prevented solely by tightening force such as tuck knitting or inserting elastic threads, the compression can become too strong or leave marks on the skin after wearing, leading to discomfort and a decrease in wearing comfort. The ankle-length footwear 1 according to the present invention focuses on elasticity and high friction to prevent slippage and slippage during walking and exercise. When the front low-stretch portion 112 is formed by inserting elastic threads within the front circumferential portion 111 which is knitted with a backing yarn that has a relatively high coefficient of friction, or when the upper low-stretch portion 132 is formed by inserting elastic threads within the upper circumferential portion 131 which is knitted with a backing yarn that has a relatively high coefficient of friction, the amount of elastic thread fed can be adjusted, and when formed with tuck knitting, the number of tucks can be adjusted, thus preventing slippage and slippage during walking and exercise without excessive tightening, unlike conventional designs that prevent slippage and slippage during walking and exercise solely by tightening force. Therefore, a wider range of people than ever before, including those with sensitive skin or children with thin skin, can wear the ankle-length footwear 1 according to the present invention with confidence.

[0032] (5) Opening of the shoe The opening portion 140 is formed on the upper side of the ankle covering portion 130, as shown in Figure 1, and is knitted from face yarn. This face yarn has a higher coefficient of friction than the face yarn used to knit the upper circumferential portion 131, and can be, for example, split fiber yarn, polyurethane, Nanofront®, or Clinpal®. The opening portion 140 also has a double-layered structure, achieved by folding the knitted fabric and then sewing it together. Elastic thread may be inserted into the opening portion 140.

[0033] <Features of the ankle-length footwear according to the first embodiment of the present invention> (1) In the ankle-length footwear 1 according to the first embodiment of the present invention, the upper circumferential portion 131 is provided around the ankle covering portion 130, and the upper low-stretch portion 132 is knitted inside the upper circumferential portion 131. Furthermore, the backing yarn used to knit the upper circumferential portion 131 has a higher coefficient of friction than the fronting yarn used to knit the upper circumferential portion 131, and the inside of the upper circumferential portion 131 has a higher coefficient of friction than the inside of the heel covering portion 120. In addition, the upper low-stretch portion 132 has less elasticity than the upper circumferential portion 131 and the heel covering portion 120. For this reason, when wearing the ankle-length footwear 1, the upper low-stretch portion 132 causes the ankle covering portion 130 to tighten around the ankle, and the upper circumferential portion 131 makes the ankle covering portion 130 less likely to slip against the ankle. Therefore, this ankle-length footwear 1 can prevent slipping and coming off during walking, exercise, and other movements while being worn, and it can also improve the wearing comfort without being too tight.

[0034] (2) In the ankle-length footwear 1 according to the first embodiment of the present invention, the front circumferential portion 111 is provided around the foot covering portion 110, and the front low-stretch portion 112 is knitted inside the front circumferential portion 111. Furthermore, the backing yarn used to knit the front circumferential portion 111 has a higher coefficient of friction than the fronting yarn used to knit the front circumferential portion 111, and the inside of the front circumferential portion 111 has a higher coefficient of friction than the inside of the heel covering portion 120. In addition, the front low-stretch portion 112 has less elasticity than the front circumferential portion 111 and the heel covering portion 120. For this reason, when wearing the ankle-length footwear 1, the front low-stretch portion 112 tightens the foot covering portion 110 on the instep and bottom sides of the foot, and the front circumferential portion 111 makes the foot covering portion 110 less likely to slip on the instep and bottom sides of the foot. Therefore, this ankle-length footwear 1 can further prevent slipping and coming off during walking, exercise, and other movements while being worn, and it can also improve the wearing comfort without being too tight.

[0035] (3) In the ankle-length footwear 1 according to the first embodiment of the present invention, the opening portion 140 is formed on the upper side of the ankle covering portion 130 and is knitted from face yarn with a higher coefficient of friction than the face yarn used to knit the upper circumferential portion 131. Therefore, in this ankle-length footwear 1, when worn, the opening portion 140 is less likely to slip against the ankle (more specifically, the upper part of the ankle that is covered by the ankle covering portion 130). Consequently, this ankle-length footwear 1 can further prevent slippage and coming off during walking, exercise, and other movements while being worn.

[0036] <Variation> (A) Although not mentioned in the previous embodiment of the ankle-length footwear 1, the outer yarn used to knit the opening portion 140 may have a higher coefficient of friction than the outer yarn used to knit the front circumferential portion 111.

[0037] (B) Although not mentioned in the previous embodiment of the ankle-length footwear 1, the front circumferential portion 111 and the front low-stretch portion 112 do not necessarily have to be formed on the foot covering portion 110.

[0038] (C) Although not mentioned in the previous embodiment of the ankle-length footwear 1, a natural resin (such as natural rubber) or synthetic resin (such as silicone rubber or urethane rubber) that serves as an anti-slip coating may be applied to the inside of the upper circumferential portion 131 or the inside of the front circumferential portion 111, and the upper circumferential portion 131 or the front circumferential portion 111 may be formed from a natural resin or synthetic resin rather than being knitted from face yarn and back yarn.

[0039] (D) Although not mentioned in the previous embodiment of the ankle-length footwear 1, the opening portion 140 does not necessarily have to be formed. Also, the opening portion 140 does not have to be a double structure; for example, it may be a single structure or a triple or more multi-layer structure.

[0040] Each of the above-mentioned variations may be adopted individually, or they may be combined as appropriate within the bounds of consistency.

[0041] -Second Embodiment- An example of a device according to the second embodiment of the present invention is the knee support 2 shown in Figure 3. The knee support 2 will be described in detail below.

[0042] The knee support 2 according to the second embodiment of the present invention, as shown in Figure 3, has a hook shape in a side view and is mainly formed from a lower opening portion 200, a lower covering portion 210, a central covering portion 220, an upper covering portion 230, and an upper opening portion 240. The main difference between the knee support 2 according to the second embodiment of the present invention and the ankle-length footwear 1 according to the first embodiment of the present invention is that the knee support 2 according to the second embodiment of the present invention has openings on both sides. These parts will be described in detail below.

[0043] For the sake of clarity, Figure 3 defines the vertical and horizontal directions. Hereafter, these directions may be used to describe the knee support 2.

[0044] (1)Lower mouth The lower opening portion 200 is formed below the lower covering portion 210, as shown in Figure 3, and is knitted from face yarn. This face yarn has a higher coefficient of friction than the face yarn used to knit the upper circumferential portion 231 (described later), and can be, for example, split fiber yarn, polyurethane, Nanofront®, or Clinpal®. The lower opening portion 200 also has a double-layered structure, achieved by folding the knitted fabric and then sewing it together. Rubber yarn may be inserted into the lower opening portion 200.

[0045] (2) Lower covering The lower covering portion 210 is a cylindrical portion for covering the lower leg, and as shown in Figure 3, it extends upward from the upper end of the lower opening portion 200 (and downward from the lower end of the central covering portion 220), and is continuous with the upper covering portion 230 via the central covering portion 220.

[0046] Furthermore, as shown in Figure 3, the lower covering portion 210 has a lower periphery portion 211 and a lower low-stretch portion 212 formed thereon, and the portion of the lower covering portion 210 that does not have the lower periphery portion 211 and the lower low-stretch portion 212 formed thereon is knitted with a highly elastic knitted fabric (as described above). The lower periphery portion 211 is provided around the lower covering portion 210 as shown in Figure 3. The lower periphery portion 211 may be provided around the lower covering portion 210 in the form of a ring without any gaps, or it may be provided around the lower covering portion 210 in the form of a ring with one or more gaps. Also, as shown in Figure 3, the rear part of the lower periphery portion 211 is connected to the rear part of the upper periphery portion 231 of the upper covering portion 230. The lower periphery portion 211 is knitted from face yarn and back yarn. The face yarn is, for example, a natural yarn such as cotton, linen, wool, or silk, or a synthetic yarn such as nylon or polyester, or a blend of these. The back yarn is a yarn with a higher coefficient of friction than the face yarn, and is, for example, a split fiber yarn, polyurethane, Nanofront®, or Clinpal®. As a result, the inside (skin side) of the lower perimeter portion 211 has a higher coefficient of friction than the inside (skin side) of the central covering portion 220. The lower low-stretch portion 212 is knitted within the lower perimeter portion 211 (inner region), as shown in Figure 3. The lower low-stretch portion 212 may be knitted closer to the center of the lower perimeter portion 211 (see Figure 3), closer to the top of the lower perimeter portion 211, or closer to the bottom of the lower perimeter portion 211. Furthermore, as shown in Figure 3, the lower low-stretch portion 212 is arranged within the lower circumferential portion 211 to form an annular shape with a gap at the rear of the lower leg below the knee. However, it may also be arranged within the lower circumferential portion 211 to form an annular shape with one or more gaps in addition to the gap at the rear of the lower leg below the knee. In other words, the lower low-stretch portion 212 may be assembled in various shapes and forms as long as it is assembled within the lower circumferential portion 211. Also, as shown in Figure 3, the rear end of the lower low-stretch portion 212 (i.e., the end on which the gap at the rear of the lower leg below the knee is formed) is connected to the rear end of the upper low-stretch portion 232 of the upper covering portion 230 (i.e., the end on which the gap at the rear of the upper leg above the knee is formed). The lower low-stretch portion 212 is formed so that its stretching is suppressed by inserting boss threads into the face threads or back threads, and it has less stretch than the lower circumferential portion 211 and the heel covering portion 120.The face yarn is, for example, a natural yarn such as cotton, linen, wool, or silk, or a synthetic yarn such as nylon or polyester, or a blend of these. The back yarn is a yarn with a higher coefficient of friction than the face yarn, for example, split fiber yarn, polyurethane, Nanofront®, or Clinpal®. The boss yarn is a yarn with high elasticity and flexibility, and it is preferable to use, for example, woolly nylon. As an alternative knitting method, the lower low-stretch portion 212 may be made less stretchy than the lower circumferential portion 211 and the heel covering portion 120 by knitting with tuck knit, reducing the gauge, inserting elastic yarn, or a combination of these methods. When inserting the boss yarn, it is preferable to pass the boss yarn to the inside of the lower circumferential portion 211, i.e., the skin side, and the length of the boss yarn passing to the skin side is preferably such that the fingers do not get caught on the boss yarn when worn. The length of the boss yarn is adjusted as appropriate according to the wearer's age, gender, physique, etc. If the boss thread is not cut where it crosses the skin side, stretching is further suppressed, effectively preventing slippage and coming off during walking, exercise, and other movements while wearing the product. If the boss thread is cut where it crosses the skin side, the elasticity is appropriately maintained, resulting in a comfortable fit with just the right amount of tightness, and also preventing slippage and coming off during walking, exercise, and other movements while wearing the product. Furthermore, if the length of the boss thread is longer than the width of the toe, cutting it where it crosses the toe prevents the toe from getting caught on the boss thread. In addition, tightening the weave around the boss thread suppresses stretching, effectively preventing slippage and coming off during walking, exercise, and other movements while wearing the product, and also prevents the boss thread from falling out.

[0047] (3) Central covering The central covering portion 220 is the part that covers the knee, and as shown in Figure 3, it extends upward from the upper end of the lower covering portion 210, and is made of a highly elastic knitted fabric (as described above). Also, as described above, the inner side (skin side) of the central covering portion 220 has a lower coefficient of friction than the inner side (skin side) of the lower peripheral portion 211, and the central covering portion 220 has higher elasticity than the lower low-stretch portion 212. Furthermore, as will be described later, the inner side (skin side) of the central covering portion 220 has a lower coefficient of friction than the inner side (skin side) of the upper peripheral portion 231, and the central covering portion 220 has higher elasticity than the upper low-stretch portion 232.

[0048] (4) Upper covering The upper covering portion 230 is a cylindrical portion for covering the area above the knee, and as shown in Figure 3, it extends upward from the upper end of the central covering portion 220 and is continuous with the lower covering portion 210 via the central covering portion 220.

[0049] Furthermore, as shown in Figure 3, the upper covering portion 230 has an upper periphery portion 231 and an upper low-stretch portion 232 formed thereon, and the portion of the upper covering portion 230 that does not have the upper periphery portion 231 and upper low-stretch portion 232 formed thereon is knitted with a highly elastic knitted fabric (as described above). The upper periphery portion 231 is provided around the upper covering portion 230 as shown in Figure 3. The upper periphery portion 231 may be provided around the upper covering portion 230 to form a ring without any gaps, or it may be provided around the upper covering portion 230 to form a ring with one or more gaps. Also, as described above, the rear part of the upper periphery portion 231 is connected to the rear part of the lower periphery portion 211 of the lower covering portion 210. The upper periphery portion 231 is knitted from face yarn and back yarn. The face yarn is, for example, a natural yarn such as cotton, linen, wool, or silk, or a synthetic yarn such as nylon or polyester, or a blend of these. The back yarn is a yarn with a higher coefficient of friction than the face yarn, and is, for example, a split fiber yarn, polyurethane, Nanofront®, or Clinpal®. As a result, the inside (skin side) of the upper periphery portion 231 has a higher coefficient of friction than the inside (skin side) of the central covering portion 220. The upper low-stretch portion 232 is knitted within the upper periphery portion 231 (inner region), as shown in Figure 3. The upper low-stretch portion 232 may be knitted closer to the center of the upper periphery portion 231 (see Figure 3), closer to the top of the upper periphery portion 231, or closer to the bottom of the upper periphery portion 231. Furthermore, as shown in Figure 3, the upper low-stretch portion 232 is arranged within the upper circumferential portion 231 to form an annular shape with a missing portion at the rear of the knee. However, it may also be arranged within the upper circumferential portion 231 to form an annular shape with one or more missing portions in addition to the rear of the knee. In other words, the upper low-stretch portion 232 may be assembled in various shapes and forms as long as it is assembled within the upper circumferential portion 231. Also, as described above, the rear end of the upper low-stretch portion 232 (i.e., the end on which the missing portion at the rear of the knee is formed) is connected to the rear end of the lower low-stretch portion 212 of the lower covering portion 210 (i.e., the end on which the missing portion at the rear of the knee is formed). The upper low-stretch portion 232 is formed so that its stretching is suppressed by inserting boss threads into the face threads or back threads, and it stretches less than the upper circumferential portion 231 and the heel covering portion 120.The face yarn is, for example, a natural yarn such as cotton, linen, wool, or silk, or a synthetic yarn such as nylon or polyester, or a blend of these. The back yarn is a yarn with a higher coefficient of friction than the face yarn, for example, split fiber yarn, polyurethane, Nanofront®, or Clinpal®. The boss yarn is a yarn with high elasticity and flexibility, and it is preferable to use, for example, woolly nylon. As an alternative knitting method, the upper low-stretch portion 232 may be made less stretchy than the upper circumferential portion 231 and the heel covering portion 120 by knitting with tuck knit, reducing the gauge, inserting elastic yarn, or a combination of these methods. When inserting the boss yarn, it is preferable to have the boss yarn cross the inside of the upper circumferential portion 231, i.e., the skin side, and the length of the boss yarn crossing the skin side should be such that the fingers do not get caught on the boss yarn when worn. The length of the boss yarn should be adjusted appropriately according to the wearer's age, gender, physique, etc. If the boss thread is not cut where it crosses the skin side, stretching is further suppressed, effectively preventing slippage and coming off during walking, exercise, and other movements while wearing the product. If the boss thread is cut where it crosses the skin side, the elasticity is appropriately maintained, resulting in a comfortable fit with just the right amount of tightness, and also preventing slippage and coming off during walking, exercise, and other movements while wearing the product. Furthermore, if the length of the boss thread is longer than the width of the toe, cutting it where it crosses the toe prevents the toe from getting caught on the boss thread. In addition, tightening the weave around the boss thread suppresses stretching, effectively preventing slippage and coming off during walking, exercise, and other movements while wearing the product, and also prevents the boss thread from falling out.

[0050] By the way, in conventional designs where slippage and slippage during walking and exercise are prevented solely by tightening force achieved through methods such as tuck knitting or inserting elastic threads, the compression can become too strong or leave marks on the skin after wearing, leading to discomfort and a reduced wearing experience. The knee support 2 according to the present invention focuses on elasticity and high friction to prevent slippage and slippage during walking and exercise. When the lower low-stretch portion 212 is formed by inserting elastic threads within the lower circumferential portion 211, which is knitted with a backing yarn that has a relatively high coefficient of friction, or when the upper low-stretch portion 232 is formed by inserting elastic threads within the upper circumferential portion 231, which is knitted with a backing yarn that has a relatively high coefficient of friction, the amount of elastic thread fed can be adjusted. Similarly, when forming with tuck knitting, the number of tuck stitches can be adjusted. Unlike conventional designs that prevent slippage and slippage during walking and exercise solely by tightening force, this design prevents slippage and slippage during walking and exercise without excessive tightening. Therefore, a wider range of people than ever before, including those with sensitive skin or children with thin skin, can wear the knee support 2 according to the present invention with confidence.

[0051] (5) Upper opening The upper opening portion 240 is formed above the upper covering portion 230, as shown in Figure 3, and is knitted from face yarn. This face yarn has a higher coefficient of friction than the face yarn used to knit the upper circumferential portion 231, and can be, for example, split fiber yarn, polyurethane, Nanofront®, or Clinpal®. The upper opening portion 240 also has a double-layered structure, achieved by folding the knitted fabric and then sewing it together. Rubber yarn may be inserted into the upper opening portion 240.

[0052] <Features of the knee support according to an embodiment of the present invention> (1) In the knee support 2 according to the second embodiment of the present invention, the upper circumferential portion 231 is provided around the upper covering portion 230, and the upper low-stretch portion 232 is knitted inside the upper circumferential portion 231. Furthermore, the backing threads that knit the upper circumferential portion 231 have a higher coefficient of friction than the fronting threads that knit the upper circumferential portion 231, and the inside of the upper circumferential portion 231 has a higher coefficient of friction than the inside of the central covering portion 220. In addition, the upper low-stretch portion 232 has less elasticity than the upper circumferential portion 231 and the central covering portion 220. For this reason, when wearing the knee support 2, the upper low-stretch portion 232 causes the upper covering portion 230 to tighten over the knee, and the upper circumferential portion 231 makes the upper covering portion 230 less likely to slip over the knee. Therefore, this knee support 2 can prevent slipping or coming off during walking, exercise, and other movements while being worn, and it can also improve the wearing comfort without being too tight.

[0053] (2) In the knee support 2 according to the second embodiment of the present invention, the lower circumferential portion 211 is provided around the lower covering portion 210, and the lower low-stretch portion 212 is knitted inside the lower circumferential portion 211. Furthermore, the backing threads that knit the lower circumferential portion 211 have a higher coefficient of friction than the fronting threads that knit the lower circumferential portion 211, and the inside of the lower circumferential portion 211 has a higher coefficient of friction than the inside of the central covering portion 220. In addition, the lower low-stretch portion 212 has less stretch than the lower circumferential portion 211 and the central covering portion 220. Therefore, in this knee support 2, when worn, the lower low-stretch portion 212 causes the lower covering portion 210 to tighten around the lower knee, and the lower circumferential portion 211 makes the lower covering portion 210 less likely to slip against the lower knee. Therefore, this knee support 2 can further prevent slippage and coming off during walking, exercise, and other movements while being worn, and it can also improve the wearing comfort without being too tight.

[0054] (3) In the knee support 2 according to the second embodiment of the present invention, the lower opening portion 200 is formed below the lower covering portion 210 and is knitted from face yarn with a higher coefficient of friction than the face yarn knitted in the upper circumferential portion 231. Similarly, the upper opening portion 240 is formed above the upper covering portion 230 and is knitted from face yarn with a higher coefficient of friction than the face yarn knitted in the upper circumferential portion 231. As a result, in this knee support 2, when worn, the lower opening portion 200 is less likely to slip against the lower part of the knee, and the upper opening portion 240 is less likely to slip against the upper part of the knee. Therefore, this knee support 2 can further prevent slippage and coming off during walking, exercise, and other movements when worn.

[0055] <Variation> (A) Although not mentioned in the previous embodiment of the knee support 2, the surface yarn used to knit the lower opening portion 200 or the upper opening portion 240 may have a higher coefficient of friction than the surface yarn used to knit the lower circumferential portion 211.

[0056] (B) Although not mentioned in the previous embodiment of the knee support 2, the lower peripheral portion 211 and the lower low-stretch portion 212 do not necessarily have to be formed on the lower covering portion 210.

[0057] (C) Although not mentioned in the previous embodiment of the knee support 2, a natural resin or synthetic resin that serves as an anti-slip coating may be applied to the inside of the upper circumferential portion 231 or the inside of the lower circumferential portion 211, or the upper circumferential portion 231 or the lower circumferential portion 211 may be formed from a natural resin or synthetic resin rather than being knitted from face yarn and back yarn.

[0058] (D) Although not mentioned in the previous embodiment of the knee support 2, the upper opening 240 or the lower opening 200 does not need to be formed. Also, the upper opening 240 or the lower opening 200 does not have to be a double structure; for example, it may be a single structure or a triple or multi-layer structure.

[0059] (E) In the above embodiment, the present invention was applied to a knee support 2, but the present invention may also be applied to an elbow support. In this case, the lower covering portion of the elbow support will cover the area below the elbow, the central covering portion of the elbow support will cover the elbow, and the upper covering portion of the elbow support will cover the area above the elbow.
