Description

【００５２】
表１に示すように、丸編み機は、２種類の糸を供給可能なものを使用し、１種類目の糸で１コース編成した後、２種類目の糸で次のコースを編成し、これを交互に繰り返すようにした。
【００５３】
具体的には、１種類目の糸として、７０ｄ（デニール）／３４ｆ（フィラメント）のウーリーナイロン糸を単独で用い、２種類目の糸としては、４０ｄ／１３ｆのウーリーナイロン糸と、３０ｄのポリウレタン糸に３０ｄのナイロン糸を巻き付けたシングルカバードヤーン（ＳＣＹ）とを併用した。そして、１番目の糸を使用するときは、平編み又はタック編みを行い、２番目の糸を使用するときは平編み又はミス編みを行うようにした。
【００５４】
図５〜７は、各編組織の組織図である。図５に示すように、第１編組織は、１コースごとに糸をかえて編成した平編み組織となる。第２編組織は、図６に示すように、１番目の糸による１：１タック編みと、２番目の糸による２：２ミス編みとの交編組織となる。また、図７に示すように、第３編組織は、１番目の糸による１：１タック編みと、２番目の糸による２：３：１：２ミス編みとの交編組織となる。
【００５５】
したがって、１番目の糸を用いるコース内において、編み組織が、第１編組織→第２編組織→第１編組織→第３編組織と変化する場合は、平編み→１：１タック編み→平編み→１：１タック編みと、編み方が変化することになる。
【００５６】
２番目の糸を用いるコース内において、編み組織が、第１編組織→第２編組織→第１編組織→第３編組織と変化する場合は、平編み→２：２ミス編み→平編み→２：３：１：２ミス編みと、編み方が変化することになる。以上の編み方により、３種類の編組織からなるタイツを作製した。
【００５７】
［伸縮性の評価］
上記タイツにおける編組織の伸縮性を評価した。評価方法としては、各編組織をタテ１０ｃｍ以上×ヨコ２．５ｃｍの大きさにカットし、つかみ間隔を１０ｃｍとして、引張速度３０ｃｍ／ｍｉｎで引張り、負荷が９．８Ｎかかったときの伸長度を測定した。表２にその結果を示す。
【００５８】
【表２】

【００５９】
表２に示すように、各編組織の伸長度の比は、第一編組織：第二編組織：第三網組織＝１：０．５８：０．３０となり、各編組織間に適度な伸縮性の差が存在することが確認された。
【００６０】
［着用テスト］

BACKGROUND OF THE INVENTION
The present invention relates to tights that are worn in close contact with the body surface of a human body and are preferably used to guide the body to a correct posture when standing or exercising.
[0002]
[Prior art]
Maintaining a good posture for the human body is important, and deterioration of posture contributes to lower body disorders such as back pain and knee pain. As a result of research conducted by the present inventor, it has been found that pains around the legs such as knees, lower legs, and Achilles tendons are caused not only by the posture at rest but also by the way the body moves during walking and running. I found it.
[0003]
For example, knee pain is often seen in sports disorders, and this is often caused by twisting and stretching the knee. However, persons with disabilities themselves are not aware that they are twisting their knees, and there has been a problem that the symptoms worsen by continuing to move the body inappropriately.
[0004]
Conventionally, exercise spats having a taping function for the purpose of improving sports obstacles are known. In this exercise spats, as shown in Patent Document 1, a predetermined portion is provided with a portion having a relatively strong tightening force and a portion having a relatively weak tightening force in a pattern shape, thereby promoting muscle expansion and contraction. In addition, it reduces the fatigue of muscles and prevents fleshing, and also exhibits a taping function that prevents rupture and damage to ligaments and tendons.
[0005]
[Patent Document 1]
JP 2001-214303 A
[0006]
[Problems to be solved by the invention]
However, the spats for exercise described above are intended to reduce the strain on the muscles by simply limiting the movable range of the muscles by the taping function, and to protect the muscles. The problem was that improper body postures and movements remained unimproved.
[0007]
Therefore, in view of the above problems, an object of the present invention is to provide a tights that can correctly guide the posture or movement of a body without impairing mobility.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, the tights according to the present invention is a tights having stretchability when worn, and is composed of a stretchable portion having high stretchability and a low stretchable portion having lower stretchability than the stretchable portion, The low expansion / contraction part is provided in an annular shape over the entire circumference of the waist part.
[0009]
Both the stretchable part and the low stretchable part have a stretchability that can sufficiently follow the movement of the body when worn, but the low stretchable part is provided so that the stretchability is lower than the stretchable part. Yes.
[0010]
Therefore, when the stretchable part and the low stretchable part are stretched by the same amount following the movement of the body, a greater load is applied to the low stretchable part, which becomes a resistance to the human body and raises the wearer's consciousness. It becomes possible to turn to a low expansion-contraction part. Then, when the tights wearer takes the correct posture, the posture of the wearer can be correctly guided by forming the low stretchable part so that the resistance force is minimized.
[0011]
In the case of the tights having the above-described configuration, the low stretchable part is provided in an annular shape around the entire circumference of the waist part. Therefore, it is possible to lead to a correct posture in which the lumbar vertebra is extended by moving the body so that the wearer himself / herself is conscious and the resistance force is minimized.
[0012]
Here, the waist part means an annular part included between the upper line up to approximately the waist line and the lower line passing through the boundary between the lumbar spine and the sacrum (corresponding to the line connecting the most protruding parts of the hip bone). .
[0013]
The stretchability of the stretchable material constituting the stretchable portion or the low stretchable portion can be evaluated by the degree of stretch when a certain load is applied. Here, the degree of elongation is a value represented by [(ba) / a] × 100, where a is the length of the original sample and b is the length of the sample in the stretched state.
[0014]
The stretchability of the low stretchable portion is not particularly limited, but is preferably formed to be 0.40 to 0.80 when the stretchability of the stretchable portion serving as the base of the tights is 1, and is further 0. The range of .50 to 0.70 is more preferable.
[0015]
As described above, the tights according to the present invention have stretchability when worn, and are secured with the lumbar vertebra extended like a conventional corset in that the mobility is ensured. The effect is different.
[0016]
When the lumbar vertebra is bent, the rear central region of the tights corresponding to the lumbar vertebral region is stretched and the resistance of the portion increases. The wearer perceives this change in resistance and moves the body so as to be in the correct posture. Therefore, it becomes easier to perceive a change in posture as the change in resistance force when the lumbar vertebra is extended and bent is larger.
[0017]
In order to increase the resistance change between when the lumbar vertebra is stretched and when it is bent, use a material with low stretchability that is as low as possible and with a slight increase in resistance. However, if the resistance of the entire low stretchable part is increased, the mobility in the waist part may be reduced.
[0018]
Therefore, in the present invention, the low expansion / contraction part is configured from a plurality of regions having different resistance forces. Specifically, the low expansion / contraction part was composed of a rear center region and other regions, and the rear center region was formed so as to be less elastic than the other regions.
[0019]
According to the above configuration, the stretchability of the rear center region is lower than the other regions, so it is easy to perceive changes in posture, and the stretchability in the other regions is greater than the rear center region, so in the waist portion There is no risk of impairing mobility.
[0020]
Further, the low stretchable part may be formed of an abdominal region, a rear center region, and both side regions, and the abdomen region and the rear center region may be formed to have lower stretchability than the both side regions. According to the above configuration, resistance acts on the abdomen that is about to protrude forward due to the bending of the lumbar vertebra, so that it is possible to more reliably lead to a correct posture in which the lumbar vertebra is extended.
[0021]
The rear center region may be formed in the waist, but it is preferable to extend to the lower sacral region. That is, the lower end of the lumbar vertebra is connected to the sacrum, and when the lumbar vertebra is bent, the sacrum below it is also bent. Therefore, if the posterior central region is formed from the waist to the sacral region, it is possible to detect changes in posture at both the lower lumbar vertebra and the sacrum, and the posture can be corrected with higher sensitivity.
[0022]
The tights need only have at least a waist part, and the length of the leg part may be any length from the crotch, above the knee, and below the knee, or may wrap the entire leg part. Good.
[0023]
In the present invention, it is possible to correctly guide not only the lumbar spine but also the leg posture. That is, a tights having stretchability, which is worn in close contact with the body surface from the waistline of the human body to the upper part of the heel, and the tights have a stretchable part having a high stretchability and a stretchability higher than the stretchable part. The low stretchable part is composed of a first belt-like part provided at a position from the outside of the thigh to the inside of the crus through the top of the patella and the inside of the thigh. The first belt-like portion is lower than the second belt-like portion and intersects with the first belt-like portion above the patella and is provided at a position extending to the outer side of the crus. It was formed as follows.
[0024]
According to the above configuration, since the first belt-like portion and the second belt-like portion are arranged so as to cross above the patella portion on both sides of the leg portion extending from the thigh to the heel, The resistance is the smallest when the knee is stretched straight. Therefore, it is possible to improve the posture of the leg portion including the O leg and the X leg. Note that the upper portion of the heel means a portion between the calf and the heel, and it is possible to detect torsion of the toe by forming both belt-like portions up to this position.
[0025]
Furthermore, a characteristic point in the tights is that the stretchability of the first belt-like portion is lower than that of the second belt-like portion, and this makes it possible to perceive knee twisting during exercise. it can. That is, if the knee is twisted during bending and stretching of the knee, the resistance force of one of the belt-like portions is increased, and the twist can be perceived.
[0026]
By recognizing the twisting of the knee, it becomes possible to correct the way the foot moves, and the burden on the knee or the like can be reduced to improve or prevent a sports disorder.
[0027]
The reason why it is possible to perceive twisting by lowering the stretchability of the first band is unknown, but the human body structure that the outer part of the thigh is more muscular than the inner part This is thought to be due to the factors. In any case, by reducing the stretchability of the first belt-like portion, the resistance force of both the first belt-like portion and the second belt-like portion can be perceived with a good balance. Therefore, it is possible to perceive twist by detecting the loss of the balance of resistance between the two.
[0028]
The first strip should be formed so that it is less stretchable than the second strip, but for specific values, you should actually try and wear tights while looking at the balance with the stretch. Just decide. Generally, when the extension degree of the second band-like part is 1, it is preferable to set the extension degree of the first band-like part in a range of 0.30 to 0.70, A range is more preferred.
[0029]
Further, in the present invention, the tights having stretchability, which is worn in close contact with the body surface from the waistline of the human body to the upper part of the heel, the tights include a stretchable portion having high stretchability and a stretchable portion. The low stretchable part is composed of an annular part provided in an annular shape over the entire circumference of the waist part and the inside of the lower leg part from above the patella part through the upper part of the patella From the first band-shaped part provided at a position reaching to the first band-shaped part passing through the inner side of the thigh, intersecting the first band-shaped part above the patella, and reaching the outer side of the lower leg It is also possible to adopt a configuration in which the upper ends of the first band-shaped part and the second band-shaped part are connected to the annular part.
[0030]
According to the above configuration, when a twist occurs between the leg portion and the waist portion, the resistance force in the belt-like portion increases, so that the pelvic twist can be perceived. Further, by connecting the annular portion and the belt-like portion, it is possible to perceive the resistance force applied from the waist to the quadriceps and ankle as one line.
[0031]
Therefore, it is possible to stabilize the movement of the hip joint and correctly guide the posture of the entire lower body, and it is possible not only to prevent sports disorders but also to improve the wearer's exercise ability. In addition, the tights for correctly guiding the posture of the leg may be provided with at least a length from the waist line to the upper part of the heel, and may wrap the entire leg.
[0032]
Tights can be formed by joining stretchable parts and low stretchable parts made of different materials, but the stretchable parts and low stretchable parts are composed of different knitting structures, and each knitting structure is integrated by circular knitting. If knitted, the stretchability of the stretchable part and the low stretchable part can be arbitrarily set. Therefore, it is possible to provide tights according to the body shape.
[0033]
When each knitted structure is knitted by circular knitting, it is preferable that the stretchable portion is knitted by flat knitting and the low stretchable portion is knitted by tack knitting and / or miss knitting. If the low stretch part is knitted by tuck knitting, the elasticity in the wale direction (vertical direction of the knitting structure) can be lowered, and if knitting by mistake knitting, the elasticity in the course direction (horizontal direction of the knitting structure) is lowered. You can (power up). If the low stretchable part is knitted by a combination of tack knitting and miss knitting, the stretchability in both the wale direction and the course direction can be lowered.
[0034]
The tights according to the present invention can form a low stretchable part so that an appropriate resistance acts from the correct posture within a range that does not impair the mobility. Thus, the proper posture can be easily maintained by applying an appropriate resistance force. This is particularly effective when it is difficult to take a correct posture by itself, such as correction of the O-leg and X-leg.
[0035]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, in the present invention, in order to explain where the low stretchable part is formed, there is a part using the name of a human muscle. First, the muscles of the human body will be explained.
[0036]
FIG. 3 is a muscle diagram seen from the front side of the lower body of the human body, and FIG. 4 is a muscle diagram seen from the rear side of the lower body of the human body (both are excerpts from “Words Ward” published by Dosha). In the figure, 21 is a thigh fascia latae muscle, 22 is a lateral vastus muscle, 23 is a rectus femoris muscle, 24 is an inner gastrocnemius muscle, 25 is a soleus muscle, 26 is a major adductor muscle, 27 is a thin muscle, and 28 is a medial broad muscle. A muscle 29 indicates the long peroneal muscle.
[0037]
1 and 2 are views showing an embodiment of a tights according to the present invention. FIG. 1 is a front view of the tights, and FIG. 2 is a rear view of the tights. This tights is formed in a length from the waistline to the upper side of the heel, and includes a stretchable portion 1 having high stretchability and a low stretchable portion having lower stretchability than the stretchable portion 1.
[0038]
The low stretchable part passes through the annular part 2 formed in an annular shape so as to include the waist part A and the side part of the abdominal part H, and passes from the outside of the thigh B to above the patella C and above the lower leg part. D After passing through the middle part of the abdomen H and the first belt-like part 3 provided at the position leading to the inside of the abdomen H, branching at the crotch part E, passing through the inside of the thigh B and above the patella C, the first belt-like part It is comprised from the 2nd strip | belt-shaped part 4 provided in the position which cross | intersects the part 3 and goes to the outer side of the leg part D, Area | regions other than the cyclic | annular part 2, the 1st strip | belt-shaped part 3, and the 2nd strip | belt-shaped part 4 are It is comprised by the expansion-contraction part 1. FIG. The first strip 3 is formed so as to be less stretchable than the second strip 4.
[0039]
The formation positions of the first belt-like portion 3 and the second belt-like portion 4 will be described using the names of human muscles based on FIGS. 3 and 4. When the tights are worn, the upper portion of the first belt-like portion 3 is the hip region. Of the patella C through the lateral part of the abdomen H, the greater trochanter part, the thigh fascia latae muscle 21 part, and the outer vastus muscle 22 part. It is formed at a position that passes through the inner part of the gastrocnemius 24 on the inner side and reaches the part of the soleus 25 via the upper part (the part between the patella C and the rectus femoral muscle 23).
[0040]
The upper end of the second belt-like portion 4 is connected to the annular portion 2 (abdominal region 2a described later) at the center of the abdomen H, and is formed as a single line through the center of the abdomen H to the tights crotch E. The crotch E branches into two left and right lines, each passing through the greater adductor muscle 26 and the inner vastus majorus 28, and above the patella C (between the patella C and the rectus femoris 23). ) At the position that intersects the first strip 3 and reaches the long peroneal muscle 29 region.
[0041]
At the intersection F where the first strip 3 and the second strip 4 intersect, the structure of the first strip 3 is used, and the second strip 4 is formed discontinuously. Thereby, it becomes possible to perceive a change in the resistance force in the first strip 3 with high sensitivity.
[0042]
The annular portion 2 includes an abdominal region 2a, a rear central region 2b, and both side regions 2c, and the abdominal region 2a and the rear central region 2b are formed to be less stretchable than the both side regions 2c.
[0043]
The abdominal region 2a is a region on the front side of the left and right hip bones in the annular portion 2, and is a belt-like region formed approximately between lines connecting the waist line and the lower left and right hip bones. In the posterior region on the back side of the left and right hip bones, a posterior center region 2b is formed with a predetermined width around the lumbar region, and both side regions 2c are formed on both sides thereof. That is, it is set as the structure where the both side part area | region 2c with a higher elasticity than both was interposed between the abdominal area | region 2a and the rear center area | region 2b with a low elasticity.
[0044]
The posterior central region 2b and the two side regions 2c are not belt-like regions such as the abdominal region 2a, but the waist line, the left and right first belt-like portions, and the reverse connecting the lower end portions of the left and right outer vastus muscles 22 from the lower sacrum G. It is formed in a wide area between the V-shaped lines and covers most of the area of the collar I.
[0045]
In the region, the rear central region 2b is formed with a width of about ½ of the total width of the rear region with the center of the rear region as the center, and the remaining regions are the side region 2c. Thereby, the lower lumbar vertebra and the sacrum are covered by the posterior central region 2b.
[0046]
In the present embodiment, since the first band-shaped part and the second band-shaped part are formed in the abdominal part H of the tights, the posterior center region 2b and the both side region 2c are also formed in the heel part I over a wide range. The resistance is applied in a well-balanced manner. As a result, the resistance is minimized when the pelvis is in a normal state, and the posture of the pelvis as well as the lumbar spine and legs can be correctly guided.
[0047]
As described above, in the present embodiment, the first strip 3, the abdomen region 2a, and the rear center region 2b are formed to have the same stretchability, and the second strip 4 and both side regions 2c have the same stretch. The former stretchability is set lower than that of the latter.
[0048]
However, in addition to the above setting, the basic relationship is that the first strip 3 is less stretchable than the second strip 4, and the abdomen region 2a and the rear center region 2b are less stretchable than the side regions 2c. If it is in the range which keeps, it is possible to change each elasticity, considering the balance of the resistance force concerning the whole lower body.
[0049]
【Example】
Hereinafter, the tights according to the present invention will be described in more detail with reference to examples, but the present invention is not limited to the examples.
[0050]
[Production of tights]
In this example, a tights having the configuration in the above embodiment was manufactured using a circular knitting machine. That is, as the knitting structure, the first knitting structure constituting the stretchable part 1, the second knitting structure constituting the second band-like part 4 and both side areas 2c, the first band-like part 3, the abdominal part area 2a and the rear central area. Tights were produced by knitting each knitting structure integrally using three types of the third knitting structure constituting 2b. Table 1 shows the contents of each organization.
[0051]
[Table 1]

[0052]
As shown in Table 1, the circular knitting machine is capable of supplying two types of yarn, knitting one course with the first type of yarn, and then knitting the next course with the second type of yarn. Were repeated alternately.
[0053]
Specifically, 70d (denier) / 34f (filament) wooly nylon yarn is used alone as the first yarn, and 40d / 13f wooly nylon yarn and 30d polyurethane are used as the second yarn. A single covered yarn (SCY) in which a 30d nylon yarn was wound around the yarn was used in combination. When the first yarn is used, flat knitting or tuck knitting is performed, and when the second yarn is used, flat knitting or mistake knitting is performed.
[0054]
5 to 7 are organization charts of each knitting organization. As shown in FIG. 5, the first knitting structure is a flat knitting structure knitted by changing the yarn for each course. As shown in FIG. 6, the second knitting structure is a knitting structure of 1: 1 tuck knitting with the first yarn and 2: 2 miss knitting with the second yarn. As shown in FIG. 7, the third knitting structure is a knitting structure of 1: 1 tuck knitting with the first yarn and 2: 3: 1: 2 miss knitting with the second yarn.
[0055]
Therefore, in the course using the first yarn, when the knitting structure changes from the first knitting structure → the second knitting structure → the first knitting structure → the third knitting structure, the flat knitting → 1: 1 tack knitting → The way of knitting changes from flat knitting to 1: 1 tuck knitting.
[0056]
In the course using the second yarn, when the knitting structure changes from the first knitting structure → the second knitting structure → the first knitting structure → the third knitting structure, the flat knitting → 2: 2 miss knitting → flat knitting → 2: 3: 1: 2 Miss knitting and knitting methods will change. Tights composed of three types of knitting structures were produced by the above knitting method.
[0057]
[Evaluation of elasticity]
The stretchability of the knitting structure in the tights was evaluated. As an evaluation method, each knitted structure is cut into a size of 10 cm or more in length and 2.5 cm in width, the grip interval is set to 10 cm, the tensile rate is 30 cm / min, and the degree of elongation when the load is 9.8 N is applied. It was measured. Table 2 shows the results.
[0058]
[Table 2]

[0059]
As shown in Table 2, the ratio of the degree of elongation of each knitting structure is 1st knitting structure: 2nd knitting structure: 3rd network structure = 1: 0.58: 0.30, and is appropriate between the knitting structures. It was confirmed that there was a difference in elasticity.
[0060]
[Wearing test]
A wearing test was performed using the tights produced in this example. As a comparative material, the entire tights were knitted only with the first knitting structure. As a result, in the sensory evaluation of the subject, the tights of this example have the least resistance when the leg, pelvis, and lumbar spine are in the correct posture in an upright posture, and the resistance increases as the posture deteriorates. Was confirmed. Thereby, it was confirmed that the tights of the present example can correctly guide the posture. On the other hand, in the comparative material, the above effect was not seen at all.
[0061]
Next, a walking test was performed when wearing tights. As a result, the tights of this example were evaluated to be easier to get out of feet, easier to bend and stretch the knee, and less to the left and right of the knee when walking as compared with the comparative material. Furthermore, after performing an uphill walking test, the amount of lactic acid accumulated in the muscle was measured. As a result, the amount of lactic acid in the tights of this example was smaller than that of the comparative material. That is, the tights of the examples were less fatigued and an effect of reducing fatigue was recognized.
[0062]
In addition, subjects with O-leg, X-leg, knee pain, lower leg pain, Achilles tendon pain, plantar aponeuritis, metatarsal pain, and hip circumference pain were asked to wear the tights of this example. In the evaluation after the period and daily life, all the symptoms were improved, but the comparative material did not confirm such effects.
[0063]
The present invention is not limited to the above embodiment, and it is needless to say that many modifications and changes can be made within the scope of the present invention. For example, the form of tights is not limited to being worn only on the lower body, but may be formed integrally up to the upper body.
[0064]
【The invention's effect】
As is apparent from the above description, according to the present invention, the tights are constituted by the stretchable portion having high stretchability and the low stretchable portion having lower stretchability than the stretchable portion, and the low stretchable portion is arranged around the entire circumference of the waist portion.
