Additionally, the lower leg rear side covering section covers the rear side of the lower leg section of a wearer while the wearable item is worn. The high compression section includes low expasion regions LER and a high expansion region HER. The low expansion regions are strip-shaped portions, are at least two in number, and extend along the direction from the knee side to the heel side of the lower leg section of the wearer while the wearable item is worn. The high expansion region is more expandable than the lower expansion region. Additionally, the high expansion region passes between the respective low expansion regions so as to separate the respective low expansion regions.

Description

harness

The present invention relates to a wearing device such as socks (socks, high socks, etc.), stockings, tights, etc., which can be worn at least on the lower leg (the region from below the knee to above the heel).

In the past, ``socks or the like in which a plurality of compression regions are formed so as to draw a U-shape from one side to the other side when worn'' have been proposed (for example, See Japanese National Publication No. 2019-518878). Socks and the like having such a compression region are said to have the effect of compressing the entire lower leg and improving venous return characteristics.

By the way, since the above-mentioned socks or the like form a compression area over the entire circumferential direction, some wearers of the socks or the like feel excessive tightening on the lower leg and feel discomfort. It is feared that

An object of the present invention is to provide a wearing device that does not significantly reduce the effect of compressing the lower leg and does not make the lower leg feel excessively tight.

The wearing device according to the first aspect of the present invention includes a front crus covering portion and a rear crus covering portion. The crus front side covering part covers the front side (shin side) of the wearer's crus in a state where the wearing tool is worn. In addition, the “lower leg” referred to here is a portion from below the knee to above the heel of a person (wearer). That is, the "lower leg" here does not include the knees and heels. The crus rear side covering part includes a high pressure part having a higher pressure than the crus front side covering part. Then, the crus rear side covering part covers the rear side (calf side) of the wearer's crus in a state where the wearing tool is worn. The crus front side covering part and the crus rear side covering part may form a tubular covering part adjacent to each other, or may form a tubular covering part with other parts sandwiched therebetween. . The high compression portion includes a low stretch region and a high stretch region. The low-stretch regions are strip-shaped regions, and there are at least two of them, and they extend along the direction from the knee side to the heel side of the wearer's lower leg when the wearing device is worn. In addition, it is preferable that the low-stretch region has a straight strip shape (a straight strip shape). Also, the high-stretch region is preferably linear (linearly extending). High stretch regions have a higher stretchability than low stretch regions. The high stretch regions pass between the low stretch regions so as to divide the low stretch regions.

In this harness, as described above, the rear crus covering portion includes a high pressure portion (that is, a compression region) having a higher pressure than the front crus covering portion. The high compression portion also includes a low stretch region and a high stretch region. At least two band-shaped low-stretch regions are formed, and the low-stretch regions extend along the direction from the knee side to the heel side of the lower leg of the wearer in the state in which the wearing device is worn. there is On the other hand, a high stretch region passes between each low stretch region so as to divide each low stretch region. For this reason, this wearing device can prevent the crus from feeling excessively tight without remarkably deteriorating the effect of compressing the crus.

The wearing device according to the second aspect of the present invention is the wearing device according to the first aspect, in which the high pressure part covers at least the heel side portion of the lower leg when the wearing device is worn.

For this reason, this wearing tool can press the heel-side portion of the lower leg of the wearer.

A wearing device according to a third aspect of the present invention is the wearing device according to the first aspect or the second aspect, wherein each of the low-stretch region and the high-stretch region has a shape symmetrical with respect to the posterior centerline. are doing. In addition, the "rear side center line" here means the center point of the upper side (upper end side) and the lower side (lower end side) of the wearing device in a state where the wearing device is laid flat so that the calf covering side faces out. It is the line connecting the center point.

Therefore, this harness can apply the same amount of pressure to the inner and outer sides of the triceps surae.

A wearing device according to a fourth aspect of the present invention is a wearing device according to any one of the first to third aspects, and further includes a knee side adjacent portion and a heel upper covering portion. The knee-side adjacent portion has a lower pressure than the high-pressure portion, and is arranged adjacent to the knee side of the high-pressure portion in a state in which the wearing tool is worn. The knee-side adjacent portion may be the opening portion. The heel upper covering portion has a lower pressure than the high pressure portion, and covers the upper portion of the wearer's heel when the wearing tool is worn. The high stretch region extends from the knee-side proximate portion to the upper heel covering portion.

As described above, this harness is provided with the knee-side adjacent portion having a lower pressure than the high-pressure portion, and the high stretch region extends from the knee-side adjacent portion to the upper heel covering portion. As a result, the wearer can easily pass the foot through the wearer and can effectively compress the lower leg of the wearer.

A wearing device according to a fifth aspect of the present invention is a wearing device according to any one of the first to fourth aspects, wherein the high pressure portion includes a first high pressure region and a second high pressure region. pressure area is included. The first high pressure area covers the heel side portion of the lower leg when the wearing tool is worn. The second high-pressure area covers the knee-side portion of the lower leg when the wearing tool is worn. The pressure in the first high pressure region is higher than the pressure in the second high pressure region.

With this harness, the first high-pressure area covers the heel-side portion of the crus, and the second high-pressure area covers the knee-side portion of the crus when the harness is worn. The pressure in the first high pressure region is higher than the pressure in the second high pressure region. For this reason, this wearing tool can make it easier to move the triceps surae than when the high pressure part is applied uniformly. Therefore, this wearing tool can make it easier to perform an action such as a walking action than in the previous case.

<Structure of the crus wearing device according to the embodiment of the present invention>
The crus wearing device according to the embodiment of the present invention is a wearing device that is worn at least on the crus, and includes, for example, socks (socks, high socks), calf sleeves (calf sleeves), leggings, leggings), stockings, tights, sweatpants, shapewear, shaping underwear, bodysuits, unitards, etc. The term "lower leg" used herein refers to a region from below the knee to above the heel. As an example of a crus wearing device according to an embodiment of the present invention, there is a high compression sock 100 shown in FIGS. 1 to 6. FIG. The high compression sock 100 will be described in detail below, and the configuration that is acceptable in the present invention will be described.

The high compression sock 100 according to the embodiment of the present invention has a substantially "<" shape in side view as shown in FIG. 1, and as shown in FIGS. , a foot covering portion 110 , a heel covering portion 120 , an upper heel covering portion 130 , an ankle covering portion 140 , a crus front side covering portion 150 , a crus rear side covering portion 160 and a cuff portion 170 . For convenience of explanation, the vertical direction, the horizontal direction, and the front-rear direction are defined in FIGS. 1 and 2 . Hereinafter, the configuration of the high compression socks 100 may be described using these directions.

It should be noted that when the lower leg fitting is a calf sleeve, the foot covering portion 110 and the heel covering portion 120 are not present. In addition, when the lower leg fitting is leggings, stockings, tights, sweatpants, shapewear, shaping underwear, bodysuit, or unitard, a thigh covering portion is provided instead of the opening portion 170, and the thigh covering portion is provided. A panty part or the like is added above the part covering part. The thigh is a part from above the knee to the crotch, and the panty part is a part that covers part or all of the region from the crotch to the waist.

The foot covering part 110 is a bag-like part for covering the part from the ankle to the tip of the toe. A toe bag portion may be formed in the foot covering portion 110 .

The heel covering part 120 is a part for covering the heel and extends rearward from the rear end of the foot covering part 110 .

The upper heel covering part 130 is a part for covering the upper part of the heel, that is, the part of the Achilles tendon, and extends upward from the rear upper end of the heel covering part 120 .

The ankle covering part 140 is a part for covering the ankle and extends upward from the front upper end of the foot covering part 110 . The ankle covering portion 140 is positioned below the front crus covering portion 150 and faces the lower end of the rear crus covering portion 160 . The ankle covering portion 140 includes the foot covering portion 110, the heel covering portion 120, the upper heel covering portion 130, the lower leg covering portion 150, the lower leg covering portion 160, and the lower pressure portion 162 of the lower leg covering portion 160 and the opening portion 170. It is formed so that the wearing pressure is higher than the pressure (that is, the ankle covering portion 140 is formed as a high-pressure wearing portion). In addition, the ankle covering portion 140 is formed so that its wearing pressure is slightly higher than the wearing pressure of the high pressure portion 161 of the crus rear side covering portion 160 .

The crus front side covering part 150 is a part for covering the front side of the crus (a state in which the high compression sock 100 is laid flat (the high compression sock 100 is folded along the fold FL shown in FIG. 1 The folded state is symmetrical, and extends upward from the front upper end of the ankle covering portion 140 . The crus front side covering part 150 forms a cylindrical crus covering part together with the crus rear side covering part 160 . It is preferable that the cylindrical lower leg covering portion has a tapered shape in which the width gradually widens from the ankle covering portion side to the opening side. Moreover, it is preferable that the total length in the vertical direction of the combined portion of the lower leg covering portion and the ankle covering portion 140 is within the range of 25 mm or more and 210 mm or less. This is because the vicinity of the minimum circumference of the crus that should be most compressed can be reliably covered. Moreover, in such a case, the ankle can be tightened in the circumferential direction by the ankle covering portion 140, and an appropriate compression effect can be obtained.

The crus rear side covering part 160 is a part for covering the crus rear side (the part on the calf side from the crease when the high compression socks 100 are laid flat), and the rear upper end of the ankle covering part 140 extends upward from the The crus rear covering portion 160 is formed of a high pressure portion 161 and a low pressure portion 162, as shown in FIGS. The low pressure part 162 is a part for mainly covering the upper part of the triceps surae muscle, and is formed above the high pressure part 161 as shown in FIGS. 1 and 2 . The high pressure part 161 is a part for mainly covering the lower part of the triceps surae muscle, and is formed below the low pressure part 162 as shown in FIGS. 1 and 2 . The high pressure part 161 has a higher pressure than the foot covering part 110 , the heel covering part 120 , the upper heel covering part 130 , the crus front side covering part 150 , the low pressure part 162 and the opening part 170 . formed to be higher. 1 and 2, in the high compression sock 100, the boundary line between the high compression portion 161 and the low compression portion 162 is downward from the front side to the rear side on the lateral side. It consists of a linearly inclined oblique line and a horizontal line extending linearly in the left-right direction (width direction) on the back side.

In addition, as shown in FIGS. 1 and 2, the high compression portion 161 is formed of seven linear low-stretch regions LER and six linear high-stretch regions HER. Therefore, the overall pressure of the high pressure portion 161 is slightly lower than that of the ankle covering portion 140 . In addition, the presence of the high stretch region HER reduces the uncomfortable tightening feeling of the wearer. The low-stretch regions LER and high-stretch regions HER alternate circumferentially (with a linear low-stretch region LER sandwiched between neighboring high-stretch regions HER), as shown in FIGS. to) is formed. In other words, the low stretch region LER and the high stretch region HER are arranged to form a vertical striped pattern along the rear centerline Ax. Therefore, the low stretch region LER and the high stretch region HER extend along the muscle fibers of the triceps surae. Therefore, the high pressure part 161 does not hinder the expansion and contraction of the muscles, so that the wearer does not feel an uncomfortable tightening feeling. Moreover, as is clear from FIGS. 1 and 2, the low stretch region LER is formed to be wider than the high stretch region HER. That is, when the low-stretch region LER is expressed as a thick strip, the high-stretch region HER can also be expressed as a thin strip. Moreover, as the term suggests, the high elongation region HER is formed so that its extensibility is higher than the elongation property of the low elongation region LER. When the high compression socks 100 are worn on the lower legs of a person, the low stretch region LER and the high stretch region HER extend along the direction from the knee side to the heel side of the triceps surae muscle. In addition, when the high compression socks 100 are worn on the lower legs of a person, each of the low stretch region LER and the high stretch region HER has a symmetrical shape with respect to the rear center line Ax of the lower leg. there is Also, a plurality of regions having different pressures may be formed in the high pressure portion 161 . Further, the high pressure portion 161 may be formed so that the pressure decreases from the heel side toward the opening side. Further, when the ankle covering part 140 applies a pressure of 10 to the ankle, it is preferable that the lower leg covering part applies a pressure of 7 to the maximum circumference of the lower leg. This is because an effective compression effect can be obtained by setting the same compression pressure ratio to this ratio. In addition, if the lower leg fitting is leggings, stockings, tights, sweatpants, shapewear, shaping underwear, bodysuit, or unitard, the compression ratio to the ankle, maximum lower leg circumference, and thigh (thigh) is 10:7:4, the same effect can be expected. The above-mentioned contact pressure is measured using a contact pressure measuring machine MST-MKIV manufactured by Salzmann.

The opening portion 170 is a portion formed for the purpose of making it easy to put on the high compression socks 100 and preventing the high compression socks 100 from slipping off. It is formed on the upper side of the cylindrical body formed by the front side covering portion 150 and the crus rear side covering portion 160 .

<Specific method for forming high compression socks according to the embodiment of the present invention>
The high compression sock 100 can be formed by various methods, but is preferably formed by knitting a knitted fabric. When the high-compression sock 100 is formed by knitting a knitted fabric, the foot covering portion 110, the heel covering portion 120, the upper heel covering portion 130, the crus front side covering portion 150, and the opening portion 170 are highly elastic. Made of knitted fabric. The highly stretchable knitted fabric can be knitted from, for example, natural fibers such as cotton, hemp, wool and silk, synthetic fibers such as nylon and polyester, or blended yarns thereof.

The foot covering part 110 may be knitted together with the heel covering part 120 or may be knitted separately from the heel covering part 120 . The length of the foot covering portion 110 can be adjusted by knitting several courses of flat knitting or the like between the foot covering portion 110 and the heel covering portion 120 .

The upper heel covering portion 130 is preferably knitted in series with the heel covering portion 120 . Note that several courses of plain knitting or the like may be knitted between the upper heel covering portion 130 and the heel covering portion 120 in terms of the design of the knitting machine. The length in the vertical direction of the upper heel covering portion 130 is preferably in the range of 35 mm to 110 mm, and the length in the circumferential direction is preferably in the range of 4 mm to 20 mm. The shape of the upper heel covering portion 130 may be a rectangle elongated in the vertical direction, or may be a triangle that tapers from the heel covering portion side to the opening side, or the arc side is the heel covering portion side. It may have a semicircular shape facing the The upper heel covering portion 130 is knitted so that its wearing pressure is lower than the wearing pressure of the ankle covering portion 140 and the high-pressure-wearing portion 161 . This is because the Achilles tendon is present in the surface layer of the body, and if the pressure applied to the upper heel covering portion 130 is excessively high, the movement of the Achilles tendon may be hindered.

The ankle covering portion 140 is preferably knitted from a high pressure knitted fabric. As a method of knitting into a high pressure knitted fabric, for example, a method of alternately knitting plain knitting and tuck knitting can be mentioned.

The low pressure portions 162 of the crus front covering portion 150 and the crus rear covering portion 160 are preferably knitted by flat knitting, mesh knitting, or the like, which is highly elastic.

In the high pressure part 161 of the lower leg covering part 160, the low stretch region LER adopts a knitting method that does not stretch easily such as tuck knitting, or adjusts cut bosses, stitches, and rubber thread feed amount. It can be organized by appropriately combining means. On the other hand, the high stretch region HER is knitted to have higher stretchability than the low stretch region LER, such as plain knitting or mesh knitting. The high elongation regions HER are preferably knitted in series along the vertical direction. In addition, the knitted fabric of the high stretch region HER is the same knitted fabric as the knitted fabric constituting the low compression portion 162 of the crus rear covering portion 160 and/or the heel covering portion 120 and the heel upper covering portion 130. good too. In addition, in order to adjust the pressure of the high pressure part 161, the high stretch region HER and the low stretch region LER are arranged alternately along the vertical direction (broken line or dotted line (high stretch region HER →low stretch area LER→high stretch area HER→low stretch area LER...))). Although the high stretch region HER can be knitted with the same number of courses, it is also possible to adjust the pressure of the high pressure portion 161 by changing the number of courses in the high stretch region HER. For example, the high stretch region HER on the wear opening side of the high compression portion 161 is knitted with 5 courses, and the number of courses of the high stretch region HER is reduced to 4 courses and 3 courses toward the foot covering portion 110. can be considered. Further, by knitting the high stretch region HER bilaterally symmetrically with respect to the rear center line Ax, it is possible to uniformly weaken the pressure applied to the high stretch region HER in the circumferential direction. Note that the rear center line Ax referred to here is the upper side (upper end side) of the opening portion 170 of the high compression sock 100 when the high compression sock 100 is laid flat so that the calf covering side faces outward. and the center point of the lower side (lower end side) of the foot covering portion 110 . Also, it is conceivable to organize many high stretch areas HER in the muscle hypertrophy of the triceps surae muscle. In such a case, the high stretch area HER is knitted left-right asymmetrically with respect to the rear center line Ax. The muscle hypertrophy of the triceps surae muscle becomes high pressure depending on the degree of expansion and contraction of the high pressure socks 100 . Therefore, by widening the high stretch region HER in the high compression portion 161, the lower leg is not tightened more than necessary, and the wearer is less likely to feel an uncomfortable feeling of tightness.

The opening 170 is preferably knitted from a loose and elastic knitted fabric. This is because by knitting the opening 170 in this way, it is possible to reduce or eliminate discomfort caused by tightening. The skin-contacting side (inner peripheral side) of the opening 170 is at least partially knitted using nylon as the front yarn. No back thread is used for the collar portion 170 . By knitting the collar portion 170 in this way, the thickness of the collar portion 170 can be reduced, making it loose and easy to stretch. The method of knitting the collar 170 is not limited to the method described above, and may be realized by combining various conventional techniques.
