Abstract
Description
Wearing equipment
[0001] The present invention relates to a harness that covers part or all of the legs.
[0002] In the past, a circular knit sock has been proposed, which has a circularly knitted toe pouch into which the entire toes are inserted and a heel pouch that encases the heel, characterized in that the meeting end of the toe pouch is circularly knitted so that it is closer to the sole of the foot than the instep end of the gore line formed on the heel pouch, and the depth of the heel pouch is deeper than the instep part that is located on the extension of the gore line (see, for example, JP 2011-144467 A).
[0003] JP 2011-144467 A
[0004] However, with circular knit socks such as those described above, even if the size is appropriate for the wearer's foot, there is a risk that the heel pouch will not fit the heel properly when worn, causing the heel pouch to shift position from the heel.
[0005] An object of the present invention is to minimize displacement of the heel covering portion from the heel when wearing a wearing device that is sized appropriately for the wearer's foot.
[0006] A wearing tool according to a first aspect of the present invention includes a first tubular portion, a second tubular portion, and a heel covering portion. The heel covering portion has a first covering portion and a second covering portion. The first covering portion is connected to the first tubular portion. The second covering portion is connected to the second tubular portion and the first covering portion. Furthermore, the ratio of the number of wales at the connection portion between the first and second covering portions to the number of wales at the first and second tubular portions (i.e., the number of wales at the connection portion between the first and second covering portions / the number of wales at the first and second tubular portions) is in the range of 1 / 44 to 1 / 6. Examples of the wearing tool include socks (socks, knee-high socks, etc.), tabi socks, stockings, and tights.
[0007] According to the above configuration, when a wearing device of an appropriate size for the wearer's foot is worn, the width (length in the course direction) of the connection portion between the first covering portion and the second covering portion can be made as close to the width of the calcaneus as possible or slightly wider than the width of the calcaneus. Therefore, with this wearing device, when the size is appropriate for the wearer's foot, the heel covering portion can fit the heel as closely as possible when worn. Therefore, with this wearing device, when the size is appropriate for the wearer's foot, displacement of the heel covering portion from the heel when worn can be minimized.
[0008] A wearing tool according to a second aspect of the present invention includes a first tubular portion, a second tubular portion, and a heel covering portion. The heel covering portion has a first covering portion and a second covering portion. The first covering portion is connected to the first tubular portion. The second covering portion is connected to the second tubular portion and the first covering portion. The number of wales at the connecting portion between the first covering portion and the second covering portion is less than the number of stitches at the edge portions (so-called gore lines) on both sides of the first covering portion and the second covering portion in the course direction. Examples of wearing tools include socks (socks, knee-high socks, etc.), tabi socks, stockings, tights, etc.
[0009] According to the above configuration, when a wearing device of an appropriate size for the wearer's foot is worn, the width (length in the course direction) of the connection portion between the first covering portion and the second covering portion can be made as close to the width of the calcaneus as possible or slightly wider than the width of the calcaneus. Therefore, with this wearing device, when the size is appropriate for the wearer's foot, the heel covering portion can fit the heel as closely as possible when worn. Therefore, with this wearing device, when the size is appropriate for the wearer's foot, displacement of the heel covering portion from the heel when worn can be minimized.
[0010] A third aspect of the present invention provides a wearing tool comprising a first tubular portion, a second tubular portion, and a heel covering portion. The heel covering portion comprises a first covering portion and a second covering portion. The first covering portion is connected to the first tubular portion. The second covering portion is connected to the second tubular portion and the first covering portion. The ratio of the number of wales at the connecting portion between the first tubular portion and the first covering portion to the number of wales at the connecting portion between the second tubular portion and the second covering portion (i.e., the number of wales at the connecting portion between the first tubular portion and the second covering portion / the number of wales at the connecting portion between the first tubular portion and the first covering portion and the number of wales at the connecting portion between the second tubular portion and the second covering portion) is within a range of 1 / 22 or more and less than 10 / 21. Examples of the wearing tool include socks (socks, knee-high socks, etc.), tabi socks, stockings, and tights.
[0011] According to the above configuration, when a wearing device of an appropriate size for the wearer's foot is worn, the width (length in the course direction) of the connection portion between the first covering portion and the second covering portion can be made as close to the width of the calcaneus as possible or slightly wider than the width of the calcaneus. Therefore, with this wearing device, when the size is appropriate for the wearer's foot, the heel covering portion can fit the heel as closely as possible when worn. Therefore, with this wearing device, when the size is appropriate for the wearer's foot, displacement of the heel covering portion from the heel when worn can be minimized.
[0012] A fourth aspect of the present invention provides a wearing tool comprising a first tubular portion, a second tubular portion, and a heel covering portion. The heel covering portion has a first covering portion and a second covering portion. The first covering portion is connected to the first tubular portion. The second covering portion is connected to the second tubular portion and the first covering portion. The ratio of the number of stitches on the edge portions (so-called gore lines) on both sides of the first and second tubular portions in the course direction to the number of wales on the first and second tubular portions (i.e., the number of stitches on the edge portions on both sides of the course direction of the first and second tubular portions / the number of wales on the first and second tubular portions) is greater than 1 / 7 and less than or equal to 11 / 42. Examples of the wearing tool include socks (such as socks and knee-high socks), tabi socks, stockings, and tights.
[0013] According to the above configuration, when a wearing device of an appropriate size for the wearer's foot is worn, the width (length in the course direction) of the connection portion between the first covering portion and the second covering portion can be made as close to the width of the calcaneus as possible or slightly wider than the width of the calcaneus. Therefore, with this wearing device, when the size is appropriate for the wearer's foot, the heel covering portion can fit the heel as closely as possible when worn. Therefore, with this wearing device, when the size is appropriate for the wearer's foot, displacement of the heel covering portion from the heel when worn can be minimized.
[0014] A wearing tool according to a fifth aspect of the present invention includes a first tubular portion, a second tubular portion, and a heel covering portion. The heel covering portion has a first covering portion and a second covering portion. The first covering portion is connected to the first tubular portion. The second covering portion is connected to the second tubular portion and the first covering portion. Furthermore, the value calculated by the formula [(length of the connection portion between the first tubular portion and the first covering portion + length of the connection portion between the first covering portion and the second covering portion) × length of the first covering portion in the wale direction / 2] and the value calculated by the formula [(length of the connection portion between the second tubular portion and the second covering portion + length of the connection portion between the first covering portion and the second covering portion) × length of the second covering portion in the wale direction / 2] are 1680.0 mm. 2 Over 3360.0 mm 2 The range is as follows: Examples of the wearing implement include socks (socks, knee-high socks, etc.), tabi socks, stockings, tights, etc.
[0015] According to the above configuration, when a wearing device of an appropriate size for the wearer's foot is worn, the width (length in the course direction) of the connection portion between the first covering portion and the second covering portion can be made as close to the width of the calcaneus as possible or slightly wider than the width of the calcaneus. Therefore, with this wearing device, when the size is appropriate for the wearer's foot, the heel covering portion can fit the heel as closely as possible when worn. Therefore, with this wearing device, when the size is appropriate for the wearer's foot, displacement of the heel covering portion from the heel when worn can be minimized.
[0016] A wearing tool according to a sixth aspect of the present invention is the wearing tool according to any one of the first to fifth aspects, wherein the ratio of the number of wales at the connection portion between the first tubular portion and the first covering portion and the number of wales at the connection portion between the second tubular portion and the second covering portion to the number of wales at the first tubular portion and the second tubular portion (i.e., the number of wales at the connection portion between the first tubular portion and the first covering portion and the number of wales at the connection portion between the second tubular portion and the second covering portion / the number of wales at the first tubular portion and the second tubular portion) is in the range of 1 / 2 or more and less than (X-2) / X, where X is an integer in the range of 52 to 120, preferably in the range of 60 to 108, and more preferably in the range of 72 to 96. Examples of the wearing tool include socks (socks, knee-high socks, etc.), tabi socks, stockings, and tights.
[0017] According to the above configuration, when the wearing tool is worn and the size is appropriate for the wearer's foot, the heel covering part can be made to fit the heel and ankle as closely as possible.
[0018] A wearing tool according to a seventh aspect of the present invention is the wearing tool according to any one of the first to fifth aspects, wherein when the heel covering portion is brought into a fitted state when worn by a wearer whose heel width is within a range of 57.0 mm to 67.0 mm, the force required to stretch the connection portion between the first tubular portion and the first covering portion and the connection portion between the second tubular portion and the second covering portion in the course direction is within a range of 1.29 N to 2.40 N, and the contraction force is within a range of 0.65 N to 1.44 N. The fitted state is a state in which the stretched fabric contracts when the wearing tool is worn by the wearer, causing the heel covering portion to fit the wearer's heel. Furthermore, at the lower limit of this numerical range of force, the heel covering portion will be in a fitted state when a wearer with the smallest heel width of 57.0 mm wears the wearing device, and at the upper limit of this numerical range of force, the heel covering portion will be in a fitted state when a wearer with the largest heel width of 67.0 mm wears the wearing device. Note that if the extension distance from the pre-extension state of the connection portion between the first tubular portion and the first covering portion and the connection portion between the second tubular portion and the second covering portion is 7.0 mm, the heel covering portion will be in a fitted state when a wearer with the smallest heel width of 57.0 mm wears the wearing device, and if the extension distance from the pre-extension state of the connection portion between the first tubular portion and the first covering portion and the connection portion between the second tubular portion and the second covering portion is 17.0 mm, the heel covering portion will be in a fitted state when a wearer with the largest heel width of 67.0 mm wears the wearing device. Alternatively, when the wearer wears the wearing tool, the heel covering portion is in a fitted state if the heel pressure value is within the range of 0.10 kPa or more and 3.00 kPa or less.
[0019] According to the above configuration, if the size is appropriate for the wearer's foot, the heel covering can fit tightly to the heel when worn. Therefore, with this wearing tool, if the size is appropriate for the wearer's foot, it is possible to further prevent the heel covering from shifting position from the heel when worn.
[0020] An eighth aspect of the present invention is the wearing device according to any one of the first to fifth aspects, wherein when a wearer with a heel width in the range of 57.0 mm to 67.0 mm wears the wearing device and the heel covering portion is brought into a fitted state, the force required to stretch the connection portion between the first covering portion and the second covering portion in the course direction is in the range of 3.29 N to 16.46 N, and the contraction force is in the range of 1.23 N to 4.78 N. The fitted state refers to a state in which the stretched fabric contracts when the wearing device is put on the wearer, causing the heel covering portion to fit the wearer's heel. Furthermore, when the lower limit of this numerical range of force is used, the heel covering portion is brought into a fitted state when a wearer with a heel width of 57.0 mm wears the wearing device, and when the upper limit of this numerical range of force is used, the heel covering portion is brought into a fitted state when a wearer with a heel width of 67.0 mm wears the wearing device. If the extension distance from the unextended state of the connection part between the first and second covering parts is 7.0 mm, the heel covering part will be in a fitted state when a wearer with the smallest heel width of 57.0 mm wears the wearing device, and if the extension distance from the unextended state of the connection part between the first and second covering parts is 17.0 mm, the heel covering part will be in a fitted state when a wearer with the largest heel width of 67.0 mm wears the wearing device. Alternatively, the heel covering part will be in a fitted state when the heel pressure value is in the range of 0.10 kPa or more and 3.00 kPa or less when the wearer wears the wearing device.
[0021] According to the above configuration, if the size is appropriate for the wearer's foot, the heel covering can fit tightly to the heel when worn. Therefore, with this wearing tool, if the size is appropriate for the wearer's foot, it is possible to further prevent the heel covering from shifting position from the heel when worn.
[0022] A wearing tool according to a ninth aspect of the present invention is the wearing tool according to any one of the first to fifth aspects, wherein when a wearer having a heel width of 57.0 mm to 67.0 mm is wearing the wearing tool, the first force required to stretch the connection portion between the first tubular portion and the first covering portion and the connection portion between the second tubular portion and the second covering portion in the course direction when the heel covering portion is fitted to the wearing tool is within the range of 1.29 N to 2.40 N. Furthermore, when a wearer having a heel width of 57.0 mm to 67.0 mm is wearing the wearing tool, the second force required to pull the connection portion between the first covering portion and the second covering portion in the course direction when the heel covering portion is fitted to the wearing tool is within the range of 3.29 N to 16.46 N. Furthermore, the ratio of the second force to the first force is within the range of 3.29 / 1.29 to 16.46 / 2.40. The fitted state is a state in which the stretched fabric contracts when the wearing device is put on a wearer, and the heel covering part fits the heel of the wearer. According to the lower limit of the numerical range of the first force, the heel covering part is in a fitted state when a wearer with a minimum heel width of 57.0 mm wears the wearing device, and according to the upper limit of the numerical range of the first force, the heel covering part is in a fitted state when a wearer with a maximum heel width of 67.0 mm wears the wearing device. When the extension distance from the pre-extension state of the connection portion between the first tubular portion and the first covering portion and the connection portion between the second tubular portion and the second covering portion is 7.0 mm, the heel covering portion will be in a fitted state when a wearer with a minimum heel width of 57.0 mm wears the wearing device, and when the extension distance from the pre-extension state of the connection portion between the first tubular portion and the first covering portion and the connection portion between the second tubular portion and the second covering portion is 17.0 mm, the heel covering portion will be in a fitted state when a wearer with a maximum heel width of 67.0 mm wears the wearing device. Furthermore, according to the lower limit of the numerical range of the second force, the heel covering portion will be in a fitted state when a wearer with the minimum heel width of 57.0 mm wears the wearing device, and according to the upper limit of the numerical range of the second force, the heel covering portion will be in a fitted state when a wearer with the maximum heel width of 67.0 mm wears the wearing device.If the extension distance from the unextended state of the connection part between the first and second covering parts is 7.0 mm, the heel covering part will be in a fitted state when a wearer with the smallest heel width of 57.0 mm wears the wearing device, and if the extension distance from the unextended state of the connection part between the first and second covering parts is 17.0 mm, the heel covering part will be in a fitted state when a wearer with the largest heel width of 67.0 mm wears the wearing device. Alternatively, the heel covering part will be in a fitted state when the heel pressure value is in the range of 0.10 kPa or more and 3.00 kPa or less when the wearer wears the wearing device.
[0023] According to the above configuration, if the size is appropriate for the wearer's foot, the heel covering can fit tightly to the heel when worn. Therefore, with this wearing tool, if the size is appropriate for the wearer's foot, it is possible to further prevent the heel covering from shifting position from the heel when worn.
[0024] A wearing tool according to a tenth aspect of the present invention is the wearing tool according to any one of the first to fifth aspects, and is made of a low gauge knitted fabric.
[0025] According to the above configuration, when wearing a wearing device that is the appropriate size for the wearer's foot, it is possible to minimize the heel covering portion's displacement from the heel while keeping the tightness as loose as possible. Furthermore, because low-gauge knitted fabrics have a small number of wales per inch, it is possible to form stitches with thick yarn or by aligning multiple thin yarns. This allows the wearing device to be bulky and thick. Furthermore, according to the above configuration, it is possible to minimize the wearer's leg getting cold when wearing a wearing device that is the appropriate size for the wearer's foot.
[0026] An attachment according to an eleventh aspect of the present invention is the attachment according to any one of the first to fifth aspects, wherein the number of wales in the first cylindrical portion and the second cylindrical portion is within a range of 48 to 120.
[0027] According to the above configuration, when the wearing tool is worn in a size appropriate for the wearer's foot, it is possible to minimize the feeling of tightness while also minimizing the displacement of the heel covering portion from the heel.
[0028] A wearing tool according to a twelfth aspect of the present invention is the wearing tool according to any one of the first to fifth aspects, wherein the first tubular part, the second tubular part and the heel covering part are made of a terry knit structure.
[0029] According to the above configuration, it is possible to improve the heat retention and cushioning properties as much as possible when wearing a wearing tool that is a size appropriate for the wearer's foot.

[0031] 1 Knee socks (wearing device) 110 Foot covering portion (first tubular portion) 120 Heel covering portion 121 Lower heel covering portion (first covering portion) 122 Upper heel covering portion (second covering portion) 130 Over-heel covering portion (second tubular portion) CP1 Connection portion between first lower heel covering portion and first upper heel covering portion (connection portion between first covering portion and second covering portion) CP2 Connection portion between lower heel covering portion and foot covering portion (connection portion between first tubular portion and first covering portion) CP3 Connection portion between upper heel covering portion and over-heel covering portion (connection portion between second tubular portion and second covering portion) LI1 Edge portions on both sides in the course direction of the lower heel covering portion (edge portions on both sides in the course direction of the first covering portion) LI2 Edge portions on both sides of the upper heel covering portion in the course direction (edge portions on both sides of the first covering portion in the course direction)
[0032] <Configuration of the wearing tool according to the embodiment of the present invention> The wearing tool according to the embodiment of the present invention is, for example, a sock (socks, knee-high socks, over-the-knee socks, etc.), tabi socks, stockings, tights, etc. One example of the wearing tool according to the embodiment of the present invention is a knee-high sock 1 shown in Figures 1 to 3. This knee-high sock 1 will be described in detail below.
[0033] 1 to 3, the knee socks 1 according to the embodiment of the present invention are mainly composed of a toe covering portion 100, a foot covering portion 110, a heel covering portion 120, and an over-heel covering portion 130. These components will be described in detail below.
[0034] (1) Toe Covering Section The toe covering section 100 is a bag-shaped section for covering the toes of the wearer, and as shown in Fig. 1, is located in front of the foot covering section 110. The toe covering section 100 is knitted, for example, by terry knitting.
[0035] (2) Foot Covering Section The foot covering section 110 is a section for covering the wearer's foot and has a cylindrical shape. As shown in FIG. 1 , the foot covering section 110 is continuous with the heel covering section 130 via the heel covering section 120. The foot covering section 110 is knitted, for example, by terry knitting. The number of wales in the foot covering section 110 is preferably in the range of 48 to 120, more preferably in the range of 65 to 105, and even more preferably in the range of 80 to 90. When the knee-high socks 1 are formed from a low-gauge knit fabric, as described below, the number of wales in the foot covering section 110 is preferably in the range of 52 to 120, more preferably in the range of 60 to 108, and even more preferably in the range of 72 to 96. Furthermore, it is preferable that the number of wales of the foot covering portion 110 is any one of a common multiple of 2 and 3, a common multiple of 2 and 4, or a common multiple of 3 and 4 within the above-mentioned range, and it is more preferable that it is a common multiple of 2, 3, and 4.
[0036] (3) Heel Covering Part The heel covering part 120 is a part that covers the heel of the wearer and is knitted, for example, by terry knitting. As shown in FIGS. 1 to 3, the heel covering part 120 is formed from a lower heel covering part 121 and an upper heel covering part 122. As shown in FIGS. 1 to 3, one end of the lower heel covering part 121 is connected to the foot covering part 110, forming a connection part CP2 between the lower heel covering part 121 and the foot covering part 110. As shown in FIGS. 1 to 3, the other end of the lower heel covering part 121 is connected to the upper heel covering part 122, forming a connection part CP1 between the lower heel covering part 121 and the upper heel covering part 122. 1 to 3, one end of the upper heel covering part 122 is connected to the heel covering part 130, forming a connection part CP3 between the upper heel covering part 122 and the heel covering part 130. The edge parts LI1 on both sides in the course direction of the lower heel covering part 121 and the edge parts LI2 on both sides in the course direction of the upper heel covering part 122 are joined together to form a gore line LI (see FIGS. 1 to 3).
[0037] When the number of wales in the connection portion CP2 is half that of the foot covering portion 110, the lower heel covering portion 121 is a single, undivided portion in the developed view of the knee-high socks 1, as shown in Fig. 2. Also, as shown in Fig. 2, one end of the lower heel covering portion 121 in the wale direction is connected to the foot covering portion 110 from one end of the foot covering portion 110 in the wale direction and one end in the course direction to one end of the foot covering portion 110 in the wale direction and the midpoint in the course direction. Also, when the number of wales in the connection portion CP3 is half that of the over-heel covering portion 130, the upper heel covering portion 122 is a single, undivided portion in the developed view of the knee-high socks 1, as shown in Fig. 2. Also, as shown in Figure 2, one end of the upper heel covering part 122 in the wale direction is connected to the heel covering part 130 from one end of the heel covering part 130 in the wale direction and one end of the heel covering part 130 in the course direction to one end of the heel covering part 130 in the wale direction and the midpoint of the heel covering part 130 in the course direction.
[0038] Furthermore, when the number of wales at the connection portion CP2 is more than half the number of wales at the foot covering portion 110, the lower heel covering portion 121 is composed of a first lower heel covering portion 121a and a second lower heel covering portion 121b in the developed view of the knee-high socks 1, as shown in Fig. 3. As shown in Fig. 3, one end of the first lower heel covering portion 121a in the wale direction is connected to the foot covering portion 110 from one end of the foot covering portion 110 in the wale direction and one end of the foot covering portion 110 in the course direction to a portion at the one end of the foot covering portion 110 in the wale direction that crosses an imaginary line that halves the foot covering portion 110 in the wale direction. This forms the connection portion CP2a between the first lower heel covering portion 121a and the foot covering portion 110. 3, the other wale end of the first lower heel cover 121a is connected to one end of the first upper heel cover 122a of the upper heel cover 122 (i.e., a connection portion CP1 is formed between the lower heel cover 121 and the upper heel cover 122). Also, as shown in FIG. 3, one wale end of the second lower heel cover 121b is connected to the foot cover 110 at one end of the foot cover 110 in the course direction at one end of the wale direction, forming a connection portion CP2b between the second lower heel cover 121b and the foot cover 110. Thus, when the number of wales at the connection portion CP2 is more than half the number of wales at the foot cover 110, the connection portion CP2 is the sum of the connection portions CP2a and CP2b. Furthermore, when the number of wales at the connection portion CP3 is more than half the number of wales in the heel covering portion 130, the upper heel covering portion 122 is made up of a first upper heel covering portion 122a and a second upper heel covering portion 122b in the developed view of the knee-high socks 1, as shown in Figure 3. As shown in Figure 3, one end of the first upper heel covering portion 122a in the wale direction is connected to the heel covering portion 130 from one end of the heel covering portion 130 in the wale direction and one end of the heel covering portion 130 in the course direction to a portion at the wale end of the heel covering portion 130 that crosses an imaginary line that halves the heel covering portion 130 in the wale direction. This forms the connection portion CP3a between the first upper heel covering portion 122a and the heel covering portion 130.3, one end of the second upper heel covering part 122b in the wale direction is connected to the over-heel covering part 130 at one end in the course direction of the wale direction of the over-heel covering part 130, forming a connection part CP3b between the second upper heel covering part 122b and the over-heel covering part 130. As described above, when the number of wales in the connection part CP3 is more than half the number of wales in the over-heel covering part 130, the connection part CP3 is the combined part of the connection parts CP3a and CP3b.
[0039] When a wearer with a heel width in the range of 57.0 mm to 67.0 mm puts on the knee socks 1 and the heel covering portion 120 is brought into a fitted state, it is preferable that the force (first force) required to stretch the connection portions CP2 and CP3 in the course direction be in the range of 1.29 N to 2.40 N, and the contracting force be in the range of 0.65 N to 1.44 N. When a wearer with a heel width in the range of 57.0 mm to 67.0 mm puts on the knee socks 1 and the heel covering portion 120 is brought into a fitted state, it is preferable that the force (second force) required to stretch the connection portion CP1 in the course direction be in the range of 3.29 N to 16.46 N, and the contracting force be in the range of 1.23 N to 4.78 N. Here, the fitted state refers to the state in which the stretched fabric contracts when the knee socks 1 are worn by a wearer, allowing the heel covering portion 120 to fit the heel of the wearer. Here, if the stretch distance from the unstretched state of the connection portions CP2 and CP3 is 7.0 mm, the heel covering portion 120 will be in a fitted state when a wearer with a minimum heel width of 57.0 mm wears the knee socks 1, and if the stretch distance is 17.0 mm, the heel covering portion 120 will be in a fitted state when a wearer with a maximum heel width of 67.0 mm wears the knee socks 1. Furthermore, if the stretch distance of the connecting portion CP1 from its unstretched state is 7.0 mm, the heel covering portion 120 will be in a fitted state when a wearer with a heel width of 57.0 mm wears the knee socks 1; if the stretch distance is 17.0 mm, the heel covering portion 120 will be in a fitted state when a wearer with a heel width of 67.0 mm wears the knee socks 1. Furthermore, the ratio of the second force to the first force is preferably within the range of 3.29 / 1.29 to 16.46 / 2.40. Details of the tensile test used to determine these forces will be described later. Alternatively, the heel covering portion 120 will be in a fitted state when the heel pressure value when the wearer wears the knee socks 1 is within the range of 0.10 kPa to 3.00 kPa. A test to verify the heel pressure value when the wearer wears the knee socks 1 will be described later.
[0040] (4) Heel Covering Portion The heel covering portion 130 is a portion for covering the portion above the wearer's heel, and is tubular in shape. The number of wales in the heel covering portion 130 is preferably within the range of 48 to 120, more preferably within the range of 65 to 105, and even more preferably within the range of 80 to 90. Note that, as will be described later, when the knee socks 1 are formed from a low-gauge knitted fabric, the number of wales in the heel covering portion 130 is preferably within the range of 52 to 120, more preferably within the range of 60 to 108, and even more preferably within the range of 72 to 96. Furthermore, within the above-mentioned ranges, the number of wales in the heel covering portion 130 is preferably a common multiple of 2 and 3, a common multiple of 2 and 4, or a common multiple of 3 and 4, and is more preferably a common multiple of 2, 3, and 4. As shown in FIG. 1, the heel covering portion 130 is mainly composed of an ankle covering portion 131, a clamping portion 132, a connecting portion 133, a partial leg covering portion 134, and the like.
[0041] The ankle covering part 131 is a part for covering the ankle of the wearer, and corresponds to the lower end of the heel covering part 130 as shown in Fig. 1. The ankle covering part 131 is knitted, for example, by terry knitting.
[0042] The clamping portion 132 covers the area slightly above the wearer's ankle and prevents the partial leg covering portion 134 from shifting position (slipping down, etc.) when the knee socks 1 are worn. As shown in FIG. 1, the lower end of the clamping portion 132 is connected to the ankle covering portion 131, and the upper end of the clamping portion 132 is connected to the connecting portion 133. Also, as shown in FIG. 1, a Sanyinjiao stimulating portion 132a is formed on the side of the clamping portion 132 at a position corresponding to the Sanyinjiao acupoint. The clamping portion 132 is knitted, for example, using terry knitting or the like.
[0043] 1, the connecting portion 133 serves to connect the clamping portion 132 and the partial leg covering portion 134. The connecting portion 133 is knitted, for example, by terry knitting.
[0044] The partial leg-covering portion 134 covers the wearer's leg from above the ankle to slightly above the knee. As shown in FIG. 1 , the lower end of the partial leg-covering portion 134 is connected to the connecting portion 133, and the upper end of the partial leg-covering portion 134 is open, forming the opening of the knee-high socks 1. The partial leg-covering portion 134 is a rib knitted fabric knitted by inserting an elastic yarn into the knitted fabric with skipped stitches using pile sinker knitting, and as shown in FIG. 1 , multiple ribs F1 and multiple grooves G1 are formed in the vertical direction (wale direction). In other words, the partial leg-covering portion 134 has multiple ribs F1 and multiple grooves G1 alternately arranged in the circumferential direction. It is preferable to use a comfortable yarn as the face yarn for knitting the partial leg-covering portion 134. Examples of yarns that are pleasant to the touch include spun yarns of rayon or acrylic, blended yarns of rayon or acrylic with other materials such as wool, staple spun yarns such as extra-long staple cotton yarns, and long-fiber yarns such as nylon and polyester yarns. High multifilament yarns are particularly preferred as long-fiber yarns. Other examples of yarns that are pleasant to the touch include decorative twisted yarns such as mohair yarns and tam yarns. To knit the partial leg covering portion 134 as a rib knit fabric using pile sinker knitting, an elastic yarn is used in addition to the face yarn. In one stitch, the elastic yarn is inserted in the course direction between the sinker loop of a stitch made by the face yarn and the needle loop of a stitch made by the face yarn adjacent to that sinker loop in the wale direction. In another stitch, the elastic yarn is inserted between the sinker loop of a stitch made by the face yarn and the needle loop of a stitch made by the face yarn adjacent to that sinker loop in the wale direction, skipping stitches between both the sinker loop of the stitch made by the face yarn and the needle loop of the stitch made by the face yarn adjacent to that sinker loop in the wale direction. The stitches in which the elastic yarn is inserted between the sinker loops and the needle loops become the stitches that form the ridge portion F1 of the rib knitted fabric, and the stitches in which the sinker loops and the needle loops are also skipped become the stitches that form the groove G1 of the rib knitted fabric.Here, the elastic yarn is preferably inserted into the knitted fabric while skipping stitches within a range of 1 to 20 in the course direction, more preferably while skipping stitches within a range of 1 to 15 in the course direction, even more preferably while skipping stitches within a range of 1 to 10 in the course direction, even more preferably while skipping stitches within a range of 1 to 6 in the course direction, and even more preferably while skipping stitches within a range of 1 to 3 in the course direction. By skipping stitches within a range of 1 to 6 in the course direction, the tubular diameter of the rib knitted fabric can be made to an appropriate thickness. Furthermore, by skipping stitches within a range of 1 to 3 in the course direction, the elastic yarn can be imparted to the rib knitted fabric with stretchability, which in turn can provide the partial leg covering portion 134 with an appropriate fit.
[0045] If the number of wales of the heel covering portion 130 is within the above-mentioned range and is any of a common multiple of 2 and 3, a common multiple of 2 and 4, or a common multiple of 3 and 4, or a common multiple of 2, 3 and 4, then, for example, the partial leg covering portion 134 can have the rib portion F1 as 1 stitch and the groove G1 as 1 stitch, the rib portion F1 as 2 stitches and the groove G1 as 1 stitch, the rib portion F1 as 1 stitch and the groove G1 as 2 stitches, the rib portion F1 as 2 stitches and the groove G1 as 2 stitches, the rib portion F1 as 3 stitches and the groove G1 as 1 stitch, or the rib portion F1 as 1 stitch and the groove G1 as 3 stitches. In such cases, the partial leg covering portion 134 can also be a plain knitted fabric that does not have a rib knit (i.e., the rib portions F1 and G1 are not formed).
[0046] Furthermore, knee socks 1 according to an embodiment of the present invention are preferably formed from a low-gauge knitted fabric knitted on a low-gauge single-cylinder knitting machine. Knitting machines can be classified as low-gauge, medium-gauge, high-gauge, etc., based on the gauge, which indicates the number of needles per inch. In the present embodiment, a gauge of 10.5 or less is considered low-gauge. The gauge is calculated by dividing the number of needles on the knitting machine by the circumference of the knitting machine's rotary hook. For example, if the rotary hook diameter (diameter) of a knitting machine is 5 inches and the number of needles on the knitting machine is 84 / (5 x 3.14) = 5.3. In the present embodiment, a low-gauge single-cylinder knitting machine with a rotary hook diameter of 3.75 inches or more and a number of needles of 120 or less (i.e., a knitting machine with a gauge of approximately 10.19 or less) is used. The number of needles per inch corresponds to the number of wales per inch in the knitted fabric. In a knitted fabric with a small number of wales per inch, such as a low-gauge knitted fabric, the gaps between the stitches are large and coarse. For this reason, in low-gauge knitted fabrics, stitches can be knitted with thick front yarns or stitches can be knitted by aligning multiple thin front yarns, which in turn allows for bulky and thick fabrics. The total denier of the front yarns is preferably within the range of, for example, 600 denier to 2000 denier. In addition to the front yarns, back yarns are also knitted in low-gauge knitted fabrics.
[0047] <Detailed Design of the Heel Covering Portion of the Knee-High Socks According to the Embodiment of the Present Invention> The heel covering portion 120 of the knee-high socks 1 according to the embodiment of the present invention is designed to satisfy at least one of the following conditions (I) to (V). It is more preferable that the design also satisfies condition (VI) in addition to at least one of conditions (I) to (V). Conditions (I) to (VI) will be explained below with reference to Figures 1 to 3.
[0048] (I) The ratio of the number of wales in the connection part CP1 to the number of wales in the foot covering part 110 and the heel covering part 130 is within the range of 1 / 44 to 1 / 6. This range is preferably 1 / 43 to 1 / 6, and more preferably 1 / 42 to 1 / 6.
[0049] (II) The number of wales in the connection portion CP1 is less than the number of stitches in the edge portions LI1 on both sides of the lower heel covering portion 121 in the course direction and the number of stitches in the edge portions LI2 on both sides of the upper heel covering portion 122 in the course direction.
[0050] (III) The ratio of the number of wales in the connection portion CP1 to the number of wales in the connection portion CP2 and the number of wales in the connection portion CP3 is within a range of 1 / 22 or more and less than 10 / 21. This range is preferably 1 / 22 or more and 2 / 5 or less, and more preferably 1 / 22 or more and 7 / 22 or less.
[0051] (IV) The ratio of the number of stitches in the edge portions LI1 on both sides of the lower heel covering portion 121 in the course direction and the number of stitches in the edge portions LI2 on both sides of the upper heel covering portion 122 in the course direction to the number of wales in the foot covering portion 110 and the heel covering portion 130 is within the range of more than 1 / 7 and not more than 11 / 42. This range is preferably not less than 4 / 25 and not more than 11 / 42, and more preferably not less than 5 / 28 and not more than 11 / 42.
[0052] (V) The value obtained by the formula [(length of connecting portion CP2 + length of connecting portion CP1) × length of lower heel cover portion 121 in the wale direction / 2] and the value obtained by the formula [(length of connecting portion CP3 + length of connecting portion CP1) × length of upper heel cover portion 122 in the wale direction / 2] are 1680 mm. 2 3360mm or more 2 It will be within the following range:
[0053] (VI) The ratio of the number of wales in the connection portion CP2 and the number of wales in the connection portion CP3 to the number of wales in the foot covering portion 110 and the number of wales in the over-heel covering portion 130 is within the range of 1 / 2 or more and less than (X-2) / X, where X is an integer within the range of 52 to 120, preferably within the range of 60 to 108, and more preferably within the range of 72 to 96. Furthermore, within this range, X is preferably any one of a common multiple of 2 and 3, a common multiple of 2 and 4, or a common multiple of 3 and 4, and more preferably a common multiple of 2, 3, and 4.
[0054] <Specific Design Examples of the Heel Covering Section of the Knee-High Socks According to the Embodiments of the Present Invention> Specific design examples of the heel covering section 120 of the knee-high socks 1 according to the embodiments of the present invention will now be described using Design Examples 1 and 2. In the following design examples, the number of wales in the foot covering section 110 and the number of wales in the heel covering section 130 are 84. Note that the present invention is not limited to the following design examples.
[0055] (Design Example 1) In design example 1, the heel cover 120 is designed as follows: Number of wales in connection portion CP1: 8 Number of stitches in edge portion LI1 of lower heel cover 121: 17 Number of stitches in edge portion LI2 of upper heel cover 122: 17 Number of wales in connection portion CP2: 42 Number of wales in connection portion CP3: 42 Length of connection portion CP1: 44.0 mm Length of connection portion CP2: 124.0 mm Length in the wale direction of lower heel cover 121: 40.0 mm Length of connection portion CP3: 124.0 mm Length in the wale direction of upper heel cover 122: 40.0 mm
[0056] From these values, the following values can be calculated: Number of wales in connecting portion CP1 / number of wales in foot cover 110 and number of wales in over-heel cover 130: 8 / 84 = 2 / 21 Number of wales in connecting portion CP1 / number of wales in connecting portion CP2 and number of wales in connecting portion CP3 = 8 / 42 = 4 / 21 Number of stitches in edge portion LI1 of lower heel cover 121 and number of stitches in edge portion LI2 of upper heel cover 122 / number of wales in foot cover 110 and number of wales in over-heel cover 130 = 17 / 84 (length of connecting portion CP2 + length of connecting portion CP1) × length in the wale direction of lower heel cover 121 / 2 = (124.0 mm + 44.0 mm) × 40.0 mm / 2 = 3360.0 mm 2 (Length of connecting portion CP3+Length of connecting portion CP1)×Length of upper heel covering portion 122 in the wale direction / 2=(124.0 mm+44.0 mm)×40.0 mm / 2=3360.0 mm 2 Number of wales in the connecting portion CP2 and the connecting portion CP3 / Number of wales in the foot covering portion 110 and the heel covering portion 130 = 42 / 84 = 1 / 2
[0057] From the above, it can be seen that the heel covering portion 120 of the knee socks 1 according to design example 1 is designed to satisfy all of the above conditions (I) to (VI). Furthermore, in the knee socks 1 according to design example 1, the ninth stitch of the wale of the connecting portion CP1 is pulled tight, and therefore cannot be visually confirmed. Therefore, in the knee socks 1 according to design example 1, the stitches of the connecting portion CP1 can be counted as eight stitches by eye, and based on this, the number of wales in the connecting portion CP1 is set to eight.
[0058] (Design Example 2) In design example 2, the heel covering portion 120 is designed as follows. Number of wales in connecting portion CP1: 2 Number of stitches in edge portion LI1 of lower heel covering portion 121: 22 Number of stitches in edge portion LI2 of upper heel covering portion 122: 22 Number of wales in connecting portion CP2 (i.e., the total number of wales in connecting portion CP2a and the total number of wales in connecting portion CP2b): 44 (= number of wales in connecting portion CP2a: 43 + number of wales in connecting portion CP2b: 1) Number of wales in connecting portion CP3 (i.e., the total number of wales in connecting portion CP3a and the total number of wales in connecting portion CP3b): 44 (= number of wales in connecting portion CP3a: 43 + number of wales in connecting portion CP3b): 44 (= number of wales in connecting portion CP3a: 43 + number of wales in connecting portion CP3b) Length of connecting portion CP1: 2.0 mm Length of connecting portion CP2: 82.0 mm Length of the lower heel covering part 121 in the wale direction: 40.0 mm Length of the connecting part CP3: 82.0 mm Length of the upper heel covering part 122 in the wale direction: 40.0 mm
[0059] From these values, the following values can be calculated: Number of wales in connecting portion CP1 / number of wales in foot cover 110 and number of wales in over-heel cover 130: 2 / 84 = 1 / 42 Number of wales in connecting portion CP1 / number of wales in connecting portion CP2 and number of wales in connecting portion CP3 = 2 / 44 = 1 / 22 Number of stitches in edge portion LI1 of lower heel cover 121 and number of stitches in edge portion LI2 of upper heel cover 122 / number of wales in foot cover 110 and number of wales in over-heel cover 130 = 22 / 84 = 11 / 42 (length of connecting portion CP2 + length of connecting portion CP1) × length in the wale direction of lower heel cover 121 / 2 = (82.0 mm + 2.0 mm) × 40.0 mm / 2 = 1680.0 mm 2(Length of connecting portion CP3+Length of connecting portion CP1)×Length of upper heel covering portion 122 in the wale direction / 2=(82.0 mm+2.0 mm)×40.0 mm / 2=1680.0 mm 2 Number of wales in the connecting portion CP2 and the connecting portion CP3 / Number of wales in the foot covering portion 110 and the heel covering portion 130 = 44 / 84 = 11 / 21
[0060] From the above, it can be seen that in the knee socks 1 according to design example 2, the heel covering portion 120 is designed to satisfy all of the above conditions (I) to (VI).
[0061] <Tensile Test 1> Here, tensile test 1, which was conducted on the connecting portions CP2 and CP3, will be described. First, three socks A were prepared, each having 42 wales and a length of 124.0 mm at the connecting portions CP2 and CP3, and three socks B were prepared, each having 66 wales and a length of 117.0 mm at the connecting portions CP2 and CP3. Here, sock A corresponds to knee-high socks 1 according to an embodiment of the present invention. Note that socks A and B are intended for wearers with a heel width in the range of 57.0 mm to 67.0 mm. Next, socks A and B were placed in an environment with a room temperature of 20°C and a relative humidity of 65% for 12 hours. Next, socks A and B were cut into pieces 1.0 cm from the bottom end of the clamping portion 132 of the heel covering portion 130 while laid flat. Here, the cut sock A portions including the heel covering portion 120 are designated as samples A1, A2, and A3, and the cut sock B portions including the heel covering portion 120 are designated as samples B1, B2, and B3. Next, with the heel covering portion 120 facing upward, for each sample, a U-shaped wire was hooked to a point 3.0 cm from the tip of the left gore line LI on the instep side so that both ends of the wire faced left, and a U-shaped wire was hooked to a point 3.0 cm from the tip of the right gore line LI on the instep side so that both ends of the wire faced right. Next, each of the wire-hooked portions was clamped in a tensile tester, and the connection portions CP2 and CP3 were pulled in the course direction at a pulling rate of 100 mm / min until they reached their peak state (i.e., a state in which they were pulled to 110% of the upper limit of the assumed heel width of 67.0 mm), and then the pulling force on the connection portions CP2 and CP3 was relaxed until they returned to their original state. Tensile test 1 was performed on each sample for two cycles. Note that the tensile tester used was an Autograph AGS-H 500N manufactured by Shimadzu Corporation. As a result of the test, the average values of the force (test force) required to stretch the connection parts CP2 and CP3 relative to the extension distance (stroke) from the state before pulling of the connection parts CP2 and CP3 for samples A1, A2, and A3, and the average values of the force (test force) required to stretch the connection parts CP2 and CP3 relative to the extension distance (stroke) from the state before pulling of the connection parts CP2 and CP3 for samples B1, B2, and B3 were as shown in Figure 4.The force required to fit the heel covering portion 120 to the heel of a wearer with a heel width of 57.0 mm and the force required to fit the heel covering portion 120 to the heel of a wearer with a heel width of 67.0 mm are shown in Table 1. Table 1 shows that when fitting the heel covering portion 120, the force required to stretch the connection portions CP2 and CP3 in the course direction is between 1.29 N (Newtons) and 2.40 N, and the contraction force is between 0.65 N and 1.44 N. The reason for using the data from the second cycle rather than the data from the first cycle is that the test results are unstable in the first cycle but become stable from the second cycle onwards. The reason for using the data from the return (when returning from the peak state to the state before pulling) as the contraction force is that the fabric, which has been stretched beyond the foot size, contracts and returns to its original state, providing a tight, comfortable fit.
[0062]
[0063] <Tensile Test 2> Next, tensile test 2, which was conducted on the connecting portion CP1, will be described. First, three socks A were prepared, each having eight wales and a length of 44.0 mm at the connecting portion CP1, and three socks B were prepared, each having 32 wales and a length of 57.0 mm at the connecting portion CP1. Here, sock A corresponds to knee-high socks 1 according to an embodiment of the present invention. Note that socks A and B are intended for wearers with a heel width ranging from 57.0 mm to 67.0 mm. Next, socks A and B were placed in an environment with a room temperature of 20°C and a relative humidity of 65% for 12 hours. Next, socks A and B were cut into pieces 1.0 cm from the bottom end of the clamping portion 132 of the heel covering portion 130 while laid flat. Here, the cut sock A portions that include the heel covering portion 120 are designated as samples A1, A2, and A3, and the cut sock B portions that include the heel covering portion 120 are designated as samples B1, B2, and B3. Next, for each sample, a U-shaped wire was hooked to a section 3.0 cm from the center of the 2.0 cm part to the left (one side of the course direction) from the midpoint of the connection portion CP1 (in other words, the intersection of the connection portion CP1 and the fold line of the knee sock 1) so that both ends of the wire were facing left, and another U-shaped wire was hooked to a section 3.0 cm from the center of the 2.0 cm part to the right (the other side of the course direction) from the midpoint of the connection portion CP1 so that both ends of the wire were facing right. Next, each hooked portion of the wire was clamped in a tensile tester, and the connection portion CP1 was pulled in the course direction at a tensile speed of 100 mm / min until it reached its peak state (i.e., a state where it was pulled to 110% of the upper limit of the assumed heel width of 67.0 mm). Two cycles of tensile test 2 were then performed on each sample. The tensile tester was an autograph AGS-H 500N manufactured by Shimadzu Corporation. As a result of the test, the average values of the force (test force) required to stretch the connection portion CP1 relative to the elongation distance (stroke) from the pre-stretched state of the connection portion CP1 for samples A1, A2, and A3, and the average values of the force (test force) required to stretch the connection portion CP1 relative to the elongation distance (stroke) from the pre-stretched state of the connection portion CP1 for samples B1, B2, and B3 were as shown in Figure 5.The force required to bring the connection portion CP1 into a fitted state where the heel covering portion 120 fits the heel of a wearer with a heel width of 57.0 mm, and the force required to bring the connection portion CP1 into a fitted state where the heel covering portion 120 fits the heel of a wearer with a heel width of 67.0 mm, are shown in Table 2. From Table 2, it can be seen that when bringing the heel covering portion 120 into a fitted state, the force required to stretch the connection portion CP1 in the course direction is within the range of 3.29 N to 16.46 N, and the contraction force is within the range of 1.23 N to 4.78 N. The reason for using the data from the second cycle rather than the data from the first cycle is that the test result values are unstable in the first cycle and stabilize from the second cycle onwards. In addition, the reason we use data on the return (when returning from the peak state to the state before pulling) as the contraction force is that it allows us to check the fit as the fabric, which has been stretched beyond the foot size, contracts and returns to its original position, tightening the foot.
[0064]
[0065] <Wear Pressure Value Verification Test> Here, we will explain a test to verify the heel pressure value when a wearer wears knee socks 1. Here, knee socks 1 are knee socks according to Design Example 1 above. In this test, heel pressure values were measured using a PRESSURE CONVERTER AMI3037-10, a round air pack, and an HQL adult female average foot shape (an average human body size dummy MSX-20 manufactured by Torso, Nanasai Co., Ltd.) in an environment of room temperature 20°C and relative humidity 65%. Specifically, a round air pack with a diameter of 20.0 mm was attached to the heel sole of an HQL adult female average foot shape, and the knee socks 1 were worn on the foot shape. The measured pressure value displayed on the PRESSURE CONVERTER AMI3037-10 was read one minute later. This measurement was performed three times; the first time was 0.16 kPa, the second time was 0.12 kPa, and the third time was 0.16 kPa. These heel pressure values are in the range of 0.10 kPa or more and 3.00 kPa or less, and it can be seen that the heel covering portion 120 is in a fitting state.
[0066] <Features of Knee-High Socks According to an Embodiment of the Present Invention> (1) In the knee-high socks 1 according to an embodiment of the present invention, the heel covering portion 120 is designed to satisfy at least one of conditions (I) to (V). Therefore, when knee-high socks 1 of an appropriate size for the wearer's foot are worn, the width of the connection portion CP1 can be made as close to the width of the calcaneus as possible or slightly wider than the width of the calcaneus. Therefore, when the size of these knee-high socks 1 is appropriate for the wearer's foot, the heel covering portion 120 can be made to fit the heel as closely as possible. Therefore, when the size of these knee-high socks 1 is appropriate for the wearer's foot, the heel covering portion 120 can be prevented from shifting out of position from the heel as much as possible.
[0067] (2) The knee socks 1 according to the embodiment of the present invention are made from a low-gauge knit fabric. Therefore, when wearing knee socks 1 that are the right size for the wearer's feet, the heel covering portion 120 can be prevented from shifting out of position from the heel as much as possible while still providing as little tightness as possible. Furthermore, when wearing knee socks 1 that are the right size for the wearer's feet, the wearer's legs can be prevented from getting cold as much as possible.
[0068] (3) In the knee socks 1 according to the embodiment of the present invention, the number of wales in the foot covering portion 110 and the number of wales in the heel covering portion 130 are within the range of 48 to 120. Therefore, when wearing knee socks 1 that are the appropriate size for the wearer's feet, the feeling of tightness can be minimized while minimizing the displacement of the heel covering portion 120 from the heel.
[0069] (4) In the knee socks 1 according to the embodiment of the present invention, the toe covering portion 100, the foot covering portion 110, the heel covering portion 120, and the over-heel covering portion 130 are knitted using terry knitting. This makes it possible to maximize the warmth and cushioning properties of the knee socks 1 when they are worn in a size that is appropriate for the wearer's feet.
[0070] <Modifications> (A) In the previous embodiment, the present invention was applied to knee-high socks 1, but the present invention may also be applied to socks other than knee-high socks 1 (socks, over-the-knee socks, etc.), tabi socks, stockings, tights, etc.
[0071] (B) In the knee socks 1 according to the previous embodiment, the toe covering portion 100, foot covering portion 110, heel covering portion 120, and over-heel covering portion 130 were knitted using terry knitting. However, these portions may be knitted using a knitting method other than terry knitting.
[0072] (C) The knee-high socks 1 according to the previous embodiment were knitted on a knitting machine with a gauge of 9.55 or less. However, the knee-high socks 1 may also be knitted on a knitting machine with a gauge greater than 9.55 and less than 10, or may be knitted on a knitting machine with a gauge of 10 or more.
[0073] (D) The knee socks 1 according to the previous embodiment were primarily comprised of the toe covering portion 100, the foot covering portion 110, the heel covering portion 120, and the over-heel covering portion 130. However, other components may be present in the knee socks 1 as long as the spirit of the invention is not impaired. Furthermore, in the knee socks 1 according to the previous embodiment, the over-heel covering portion 130 was primarily comprised of the ankle covering portion 131, the pressure-fitting portion 132, the connecting portion 133, and the partial leg covering portion 134. However, other components may be present in the heel covering portion 130 as long as the spirit of the invention is not impaired. Furthermore, the pressure-fitting portion 132, the connecting portion 133, and the partial leg covering portion 134 may not be formed in the heel covering portion 130. In such a case, the ankle covering portion 131 may be extended upward so as to cover the area slightly below and slightly above the knee of the wearer in addition to the ankle.
[0074] (E) Although not mentioned in the description of the knee-high socks 1 according to the previous embodiment, the knee-high socks may be designed so that the ratio of the length of the connection portion CP1 when laid flat (laid length) to the length of the connection portion CP1 when stretched in the course direction with a force of 34.3 N is between 100% and 186%. With these knee-high socks, if the size is appropriate for the wearer's foot, the risk of the width of the connection portion CP1 being narrower than the width of the calcaneus when worn can be minimized. Therefore, with these knee-high socks, the heel covering portion 120 fits the heel as closely as possible when worn, minimizing the heel covering portion 120 from shifting out of position from the heel.
[0075] The above-described modifications may be adopted individually or in appropriate combinations within a range that does not cause any contradictions.
