Description

  The present invention relates to innerwear that can support the wearer's daily movement, and in particular, has a taping function that supports the movement of the wearer from the chair sitting position to the standing position (hereinafter referred to as “standing”). The present invention relates to inner wear.

  In conventional sports clothing, it is long tights made of stretchable material, and the material constituting the lower leg is more intense than the material constituting the thigh with the line immediately below the knee joint as the boundary. By increasing the height, the clothing pressure in the lower leg is higher than that in the thigh (see, for example, Patent Document 1).

  Moreover, in the clothes which have the conventional leg part, it is pantyhose, the lower leg part consists of three ring-shaped parts with different tightening force in the foot length direction, and the thigh part has different tightening force in the foot length direction. Since it consists of two ring-shaped parts, the leg part other than the foot part as a whole consists of five ring-shaped parts with different tightening forces (see, for example, Patent Document 2).

  In addition, conventional tights adopt the most suitable knitting structure and thread use corresponding to each part such as the abdomen, buttocks, legs, etc., and have excellent detachability and wearing feeling such as heat retention and comfortable feeling of the panty part (See, for example, Patent Document 3).

  In addition, in the conventional taping function tights, the front body, the shin member, the side member, and the inner member are gathered at one stitching point at the lower side of the knee position, and have a hard stretch strength from both sides. Since the both mountain-shaped side ends of the armpit side member and the inner member are connected, the wearer's knee is supported from the lower side with a high expansion / contraction action (see, for example, Patent Document 4).

  In addition, in conventional exercise spats, a portion having a relatively strong fastening force and another portion having a relatively weak fastening force are provided in a pattern in accordance with a request for muscle support necessary for exercise. The portion having a relatively strong fastening force is a portion formed by a cut boss knitting method (see, for example, Patent Document 5).

In the conventional exercise support tights, the band-like third region extending from the waist of the wearer to the outer side of the thigh and the inner side of the lower leg has a tightening force equal to or less than that of the first region and the second region. On the other hand, the belt-like fourth region that extends from the inner side of the wearer's thigh to the outer side of the lower leg and intersects the third region at the upper part of the wearer's knee has weaker tightening force than the first region, the second region, and the third region. The tightening force is made stronger than other regions (weak regions) (see, for example, Patent Document 6).

Conventional pantyhose and tights are required to have excellent detachability and wearing feeling and do not support knee joint movement.
In addition, the conventional taping function tights, exercise spats and exercise support tights have a region having a high fastening force in the thighs in the circumferential direction of the legs in order to suppress excessive vibration of the muscles. The tightening of the legs in the thigh in the circumferential direction has a problem in that blood flow is disturbed and the wearer feels uncomfortable. In addition, there is a problem that the blood flow volume and skin temperature in the peripheral part of the leg are greatly reduced. Particularly in middle-aged and elderly people, there has been a problem that plastic deformation (collapse of skin surface tissue) occurs in the leg due to strong compression. In addition, since the dimensional change of the knee is significant, the conventional taping function tights, exercise spats, and exercise support tights cover the knee joint with a region having a high fastening force so that the legs can be bent easily.

(First embodiment of the present invention)
FIG. 1 is a front view showing a tights according to a first embodiment for carrying out the present invention, and FIG. 2 is a schematic configuration diagram of a knitting structure of a strong tightening region in the tights shown in FIG.
In FIG. 1 and FIG. 2, the inner wear wraps around at least the knee joint of the wearer and is in close contact with the body surface. For example, a rubber cloth supporter used to protect the wearer's knee joint, tights wrapped tightly from the waist to the toe of the wearer, or a long pant-like shape that adheres tightly to the wearer's leg made of a stretchable material Spats or sports tights. In the first embodiment, a description will be given using tights 1 as inner wear.
The tights 1 are roughly divided into three parts: a panty part 2, a leg part 3, and a foot part 4.

  The panty part 2 includes a waist band 2b that is a part of the rubber tape of the waist 2a, a panty 2c that is a part that covers the waist of the wearer, and a gusset 2d that is an attachment fabric for the wearer's crotch. It is a general term for parts from the top 2a to body part switching.

  In addition, the leg 3 is a part of the leg 3 corresponding to the thigh of the wearer's thigh 3a, and a leg 3b that is the center of the leg 3 and corresponding to the midpoint of the wearer's patella. And an ankle 3c which is the narrowest part corresponding to the wearer's heel at the upper part of the heel 4a, which will be described later, and is a general term for the part from the crotch 3a to the ankle 3c.

  Further, the foot part 4 reinforces a heel 4a that is a part that reinforces a part corresponding to the wearer's heel, a sole 4b that is a part that corresponds to the sole of the wearer, and a part that corresponds to the wearer's toe. It is a generic name from heel 4a to toe 4c.

  The tights 1 are integrated using a pair of knitted fabrics that are knitted in a cylindrical shape by an existing sock knitting machine, cut into portions corresponding to the panties 2c, sewed together with cutting edges, The tow 4c is sewn in a bag shape, and is knitted by a known means except for the strong tightening region 5 and the locking portion 6 described later. Further, the base fabric portion 7 that is a portion excluding the strong tightening region 5 and the locking portion 6 in the leg portion 3 is an elastic knitted fabric, and is a flat knitting, a tack knitting, a floating knitting, a pile knitting, or the like. It is the composition formed.

  The strong tightening region 5 is provided on the front side of the tights 1, covers the wearer's patella, and extends in the length direction L of the leg from the patella to the thigh and the crus. That is, the strong tightening region 5 includes a first region 8 that covers a portion of the leg portion 3 corresponding to the wearer's patella centering on the leg 3b, and extends from the first region 8 to the crotch 3a and the ankle 3c. Each of the leg portions 3 extends in the length direction L. In the first embodiment, the strong tightening region 5 is about 29 cm on the crus side along the length direction L of the leg from the position of 20 cm on the thigh side with respect to the midpoint of the patella. It extends to the position, but is not limited to this length.

Further, in the strong tightening region 5, the stretch resistance in the length direction L of the wearer's leg is larger than the stretch resistance in the circumferential direction H of the leg.
Here, the tension when given a certain extension from the state of not giving the extension the material as F, of the strong clamping area 5 in the length direction L tension F _L, a region with strong clamping in the circumferential direction H of the leg portion 5 tension F _H, the tension F _L of the base fabric part 7 in the length direction L (B), when the tensile force F _H of the base fabric part 7 in the circumferential direction H (B), strong clamping region 5 base fabric section It is preferable to have a magnitude relationship of F _L > F _H > F _L (B) ≈F _H (B)> 0 so as to have a strong tightening force compared to 7.

  Further, the strong tightening region 5 is locked to the wearer's patella by locking portions 6 on the thigh side and the crus side. In addition, in this 1st Embodiment, the latching | locking part 6 respond | corresponds to the thigh 3a which is a position corresponding to a wearer's thigh, the 1st latching | locking part 6a, and a wearer's lower leg part. The second locking portion 6b is provided between the first region 8 and the ankle 3c, and the upper end 5a and the lower end 5b of the strong tightening region 5 in the length direction L of the leg portion 3 are The first locking portion 6a and the second locking portion 6b are close to each other.

  Further, the back ground of the tights 1 is formed so that the friction coefficient of the first locking portion 6 a is larger than the friction coefficient of the strong tightening region 5. Further, the back ground of the tights 1 is formed so that the friction coefficient of the second locking portion 6b is larger than the friction coefficient of the strong tightening region.

Next, the knitting structure of the strong tightening region 5 will be described with reference to FIG.
In the first embodiment, a spliced yarn knitting and a rubber knitting (rib knitting, knitting knitting) are used together in the strong tightening region 5 to form a knitted fabric. In addition, the spliced yarn knitting is performed by adding other knitting yarn 9b in addition to the ground knitting yarn 9a of the rubber knitting, thereby appropriately suppressing expansion and contraction in the length direction L of the strong tightening region 5. Another knitting yarn 9b is cut at the boundary between the strong tightening region 5 and the base fabric portion 7 (hereinafter referred to as a cut boss).
Here, it is assumed that the other column of the loop is the course C and the fresh row is the wale W.

  As shown in FIG. 2, a 1 × 1 rubber knitting in which the front wales and the back wales are arranged alternately in the vertical direction and the front knitting and the back knitting are arranged for each wale, Many change rubber knitting such as 2 × 1 rubber knitting and 3 × 2 rubber knitting may be used. In addition, a pearl knitting (not shown) has a significant stretchability in the warp direction, whereas this knitted fabric has a stretchability in the transverse direction. In FIG. 2, the ground knitting yarn 9 a (other knitting yarn 9 b) is shown by a solid line and a broken line every other course so that the yarn connection can be easily understood. The strong tightening region 5 is not limited to this knitting structure or splicing yarn as long as the stretch resistance in the length direction L is larger than the stretch resistance in the circumferential direction H. Alternatively, an insertion knitting in which a rubber thread is knitted without making a stitch between the knitted fabrics may be performed.

Next, the knitting structure of the locking portion 6 will be described.
In the first embodiment, in addition to the ground knitting yarn, part of the base fabric portion 7 adjacent to the upper end 5a and the lower end 5b of the strong tightening region 5 is a fiber made of a thin nylon fiber (hereinafter referred to as wool). In this case, the friction coefficient of the locking portion 6 is increased with respect to the friction coefficient of the strong tightening region 5.

  If the friction coefficient of the locking portion 6 can be increased with respect to the friction coefficient of the strong tightening region 5, it is not limited to this knitted structure or wooly nylon as a splicing yarn, but is made of a material having a large friction coefficient. An object may be sewn as the back ground of the base fabric portion 7, or the back ground of the base fabric portion 7 may be coated with a resin such as polyurethane resin.

  Next, the effect of the strong tightening region 5 in the first embodiment will be described by examining the effect of taping using a stretchable tape for the knee joint, which is the principle in creating the present invention. To do.

First, the experimental method will be described.
The width of the tape 10 used in this experiment is 7.5 cm. As shown in FIG. 3, the tape 10 is supported by the taping method 1 (hereinafter referred to as S type) corresponding to the present invention and the patella from below. Two types of taping methods 2 (hereinafter referred to as X type) corresponding to such conventional tights were tested.

  In the S type, with the subject bending the knee lightly by about 30 °, the tape 10 of about 29 cm is slightly pulled in the length direction L of the leg 12 from the position of about 20 cm above the center point 11 of the patella. Then, taping was performed straight.

In the X type, the tape 10 is pulled like the S type from the outer side and the inner side of the thigh approximately 20 cm above the midpoint of the patella, and taping straight to both sides of the patella. The tape 10 was crossed at the lower edge of the patella so as to sandwich the patella, and one end of each tape 10 was stuck to the lower side of the medial and lateral condyles.
These two types of taping were performed on bare feet (hereinafter referred to as C) and normal type sports tights (hereinafter referred to as A).

The test subjects were 8 female college students with a national average body shape, age 19-21, height 160.9 ± 6.0 cm, weight 57.4 ± 4.0 kg, BMI 22.3 ± 1.9. did.
Five of the eight subjects performed three types of experiments in which bare feet and S and X-type taping were performed on the bare feet. In addition, all subjects (eight persons) performed three types of experiments in which only sports tights (A), taping of S type (hereinafter referred to as As) and X type (hereinafter referred to as Ax) were performed after wearing sports tights. I did it.

As a result of calculating the elongation ratio ε of the tape 10 from the length of the tape 10 before and after taping, the average was about 22.2 ± 4.8% for the S type and about 28.1 ± 4.9% for the X type. there were.
To measure the elongation characteristics of tape and tights materials, a tensile / shear measuring device (Kato Tech, KESFB1-AUTO-A) was used. The measurement conditions were a tensile speed of 0.2 mm / sec, a grip length of 5.0 cm, and a maximum. The load was 2.9 N / cm and the grip width was 7.5 cm, the same as the tape width.

As shown in FIG. 4, when viewed in the length direction, the tape (T ₀ ) has a large non-linearity up to about 60% and stretches very well. I understand that. In the width direction, the tape is hardly stretched because it is a one-way stretch material. Sport tights (A) is a two-way stretch material that stretches linearly up to 60-70% in both the length and circumferential direction of the legs, but is somewhat difficult to stretch thereafter. However, in the tights material (A + T) that has been subjected to taping, the stretch of the tape is added and it is difficult to stretch. Further, the 15th (T ₁₅ ) characteristic by repeated pulling in the length direction of the tape was good in recoverability with no significant difference although elongation resistance was slightly smaller than T ₀ .

  For measuring the clothing pressure of sports tights, an AMI3037 clothing pressure measuring device was used. About 0.3 ml of air was sealed in an air pack sensor having a diameter of 20 mm so as to have a thickness of about 1 mm. As shown in FIG. 11, there are five measurement points: 1) on the rectus femoris, 2) on the biceps femoris, 3) on the lateral vastus muscle, 4) on the minimum front of the thigh, and 5) on the patella midpoint. . The posture at the time of measurement was standing and chair sitting.

  For the measurement of myoelectric potential, the subjects were in a 19.0 ± 2.0 ° C., 55.0 ± 5.5% RH laboratory, 100% cotton short-sleeved T-shirt and training wear outerwear, 100% polyester. Wearing shorts for training and sneaker socks that do not cover the lower leg. In addition, sneakers that were used to each person were used.

  The subjects used a chair adjusted to the same height as their sitting popliteal height to see the effect on the active muscles during knee joint movement, and transmitted a metronome with a constant rhythm at a tempo of 60 times / minute A reciprocating motion of standing and sitting was performed according to the sound.

  The exercise from the sitting position to the standing position (1 second), the rest (1 second), the movement from the standing position to the sitting position (1 second), and the rest (1 second) were performed 15 times. Then, after a break for about 10 minutes, the sample was replaced and the experiment was repeated. The experiment was conducted for a total of 2 days.

  On the first day, an experiment was first performed in a bare foot state (C), and then an experiment was performed with two tapings S and X in a random order of taping. On the second day, the same experiment was conducted on the tights samples A, As, and Ax with the wearing order being random.

As shown in FIG. 5, the myoelectric potential measurement sites are the rectus femoris muscle (RF) and lateral vastus muscle 14 on the front surface of the thigh, which is considered to have a great influence on the knee joint movement. (Vastus lateralis muscle: VL) and biceps femoris muscle 15 (Biceps femoris muscle: BF) on the back of the thigh. All measurements were made with the right leg so that no.
By the bipolar electrode method, the action potential on each muscle abdomen was amplified by a multichannel amplifier (manufactured by Nihon Kohden Co., Ltd.), and an electromyogram (EMG) was recorded.

Next, an electromyogram analysis method will be described.
In the movement from the chair sitting position to the standing position (“standing”) and the movement from the standing position to the chair sitting position (hereinafter referred to as “sitting”), as shown in FIG. The lateral vastus muscles 14 and biceps femoris muscles 15 are used. When looking at the magnitude of these amplitudes, when standing, all muscles are not only when the motion is changed, but also in a standing posture This tendency is particularly remarkable in the rectus femoris 13.

In addition, in the “sitting” state, it can be seen that the potential generation is instantaneous.
Electromyogram (EMG) analysis was performed using BIMTUSII (manufactured by Kissei Comtech Co., Ltd.), and after adjusting the baseline level to 0 on the raw waveform of the electromyogram, full-wave rectification was performed (FIG. 6B). ), An electromyogram integral value (hereinafter referred to as an integral electromyogram (IEMG)) at a fixed time was calculated and examined. The calculation formula is as shown in the following formula (1).

I
The EMG calculates the “stand” and “sit” movements for 1 second at the time of movement change, deletes the first 5 times until the subject gets used to the rhythm of movement, and calculates the average value for each movement. It was. In general, it is known that the integral electromyogram increases as the muscle load increases.

Next, the analysis result will be described.
FIG. 6 (a) shows that the rectus femoris 13 and the outer vastus muscle 14 which are quadriceps work greatly in the raw waveform of the electromyogram (the biceps femoris 15 hardly works). This shows that the muscles involved in knee extension movements are both active muscles, both standing and sitting.

First, the influence of taping on the integral electromyogram during bare foot will be described.
FIG. 7 shows an integral electromyogram of “standing” and “sitting” in the bare feet (C) and the S and X types taping the bare feet.

  As shown in FIG. 7, in “standing”, IEMG is smaller when taping is performed on all the muscles of the rectus femoris 13, lateral vastus muscles 14 and biceps femoris 15 than the bare feet, and the rectus femur 13 and In the lateral vastus muscle 14, muscle activity in the S type was smaller than that in the X type and significantly smaller than C (*: p <0.05).

  In addition, the IEMG of “sitting” is not statistically significant than C, but the IEMG of the outer vastus muscle 14 has a magnitude relationship of C> X> S, and there is a tendency that the muscle activity is the smallest in the S type. It was. However, the integrated electromyogram of the rectus femoris 13 was reduced to about 70% of the “standing” muscle activity, and there was almost no difference between taping.

  In addition, since the integral electromyogram is said to have large individual differences due to differences in the size of the subject's muscles, how to use the muscles during operation, how to apply fat, etc., using the following equation (2), The analysis was performed by calculating the rate of change of the integrated electromyogram from the bare feet (C) of each subject (hereinafter referred to as ΔIEMG). Here, Ec is IEMG at the time of bare foot, and E is IEMG at the time of taping.

ΔIEMG = ((E−Ec) / Ec) × 100 (2)
FIG. 8 shows ΔIEMG of the rectus femoris 13 and the lateral vastus muscle 14 that was greatly involved in knee joint movement. In “standing”, σ _RF.S = 7.88, σ _RF.X = 8.26 , Σ _VL.S = 8.72, σ _VL.X = 14.11, and in “sitting”, σ _RF.C = _1.11.10 , σ _RF.S = 16.61, σ _VL.S = 14 .62, σ _VL.X = 17.96. In addition, σ represents an average value of standard deviation, and a suffix of σ represents a streak and a sample.

  As shown in FIG. 8, in “standing”, ΔIEMG of the rectus femoris 13 and lateral vastus muscle 14 decreased by about 5 to 10% in the S and X types, and the decrease in the S type was larger than that in the X type. It was.

  In order to consider the above results from the elongation characteristics of the tape accompanying knee joint motion, taping of S and X types was performed on one subject using a tape with a line marked every 5 cm in a stationary state. The elongation ratio of the tape at the standing position and the chair sitting position was calculated.

  According to this, in the S type, the elongation rate of the tape near the patella was about 20% when standing, whereas a large elongation of about 50% was recognized when sitting on the chair. From this, in "standing", since the recovery force of the extended tape assists the contraction of the muscles in the front of the thigh, it is considered that ΔIEMG is reduced in the straight femur 13 and the lateral vastus muscle 14 in the S type rather than bare feet. Is done.

  On the other hand, in the X type, the tape stretch rate around the patella is about 20% in both the standing position and the chair sitting position, and the change in the tape stretch rate with movement is small. It is thought that it did not promote.

  Further, as shown in FIG. 8, in “sitting”, ΔIEMG of rectus femoris 13 is about the same as that of bare feet for both S type and X type, whereas ΔIEMG of outer vastus muscle 14 is about S type. It decreased by 10%. This is presumably because the elongation resistance of the tape accompanying “sitting” played a role of braking to the operation and assisted the stretch contraction of the muscle. In the X type, ΔIEMG was almost 0 even in the outer vastus muscle 14.

  From the above results, the S type that tapers the patella straight from the front of the thigh to the front of the lower leg, compared to the X type that fixes the patella so as to sandwich the knee, such as “standing” and “sitting” In the exercise, it is considered that the elasticity of the tape can assist the activity of the rectus femoris 13 and the outer vastus muscle 14 and reduce the muscle load.

Next, the influence of taping on the integrated electromyogram when wearing sports tights will be described.
FIG. 9 shows an integrated electromyogram when “standing” and “sitting” are performed while wearing tights.

  As shown in FIG. 9, there was a tendency for the IEMG to become slightly smaller than before taping by performing the taping on the tights in both the operations of “standing” and “sitting”.

  As in the case of taping at the time of bare feet as described above, in the rectus femoris muscle 13 and the lateral vastus muscle 14 that are greatly involved in “standing” and “sitting”, the integrated electromyogram of each muscle when wearing only tights is used as a reference. As a result, the change rate ΔIEMG was obtained from the previous equation (2). The result is shown in FIG.

FIG. 10 shows ΔIEMG of the rectus femoris muscle 13 and the lateral vastus muscle 14 that were greatly involved in knee joint movement.
As shown in FIG. 10, in “standing”, ΔIEMG is about −5% for the rectus femoris 13 and about −10% for the lateral vastus muscle 14 for both As and Ax, and tends to decrease more in As than in As. These were almost the same as the results in the case of taping with bare feet described above (FIG. 8).

  Here, as shown in FIG. 11, the difference in clothing pressure between “standing” and “sitting” is greatest at the midpoint of the round numeral 5 patella, and the clothing pressure at the midpoint of the round numeral 5 at the chair sitting position is As. About 8 kPa, Ax is about 6.5 kPa, and A is about 5 kPa. Since the clothing pressure is proportional to the tension of the fabric, the recovery force from the extension is large in the order of As> Ax> A, and this assists the muscular contraction of the rectus femoris 13 and the outer vastus muscles 14, thereby reducing the muscle load. It seems to have been.

  On the other hand, as shown in FIG. 10, in “sitting”, ΔIEMG tended to decrease by about 5% only with As of the rectus femoris 13, and no effect on other muscles was observed. As a cause of this, in the case of sports tights, it is considered that a part of the increase in body dimensions accompanying movement is compensated by the shift of the sports tights toward the trunk. That is, the assisting action of the stretch contraction of the muscle is reduced as compared with the case where the tape is directly applied to the skin.

  From the above results, even when the taping is performed not only on the bare feet but also on the tights, especially in “standing”, the S-type taping causes the muscle burden on the rectus femoris 13 and the outer vastus muscle 14 in the knee joint movement. It was found to reduce.

Finally, the interrelationship between active muscles will be described.
The rate of change of both the rectus femoris muscle 13 and the lateral vastus muscle 14 in “standing” where the influence on the knee joint movement was great by performing taping on bare feet and tights was examined.

  As shown in FIG. 12, ΔIEMG of the lateral broad muscle 14 on the horizontal axis is almost the same as the effect of taping in the case of bare feet and wearing tights, but in the rectus femoris 13, taping was performed on the tights. In the case, the amount of decrease in ΔIEMG was smaller than that in the case of bare feet. As described above, this is considered to be caused by the deviation of the tights accompanying the operation, and shows that even if taping is performed on the tights, the effect of taping that is as large as bare feet cannot be obtained.

  As described above, the taping method 1 (S type) corresponding to the present invention, in which the tightening force is increased in the length direction of the leg from the thigh to the lower leg around the midpoint of the patella, Compared to the corresponding taping method 2 (X type) that does not cover the patella and crosses the taping at the lower edge of the patella, the rectus femoris 13 and the lateral vastus muscles during knee joint movement such as “stand” and “sit” The muscle burden to 14 can be reduced. In particular, in “standing”, the S-type taping can reduce the muscular load on the rectus femoris 13 and the outer vastus muscle 14 in the knee joint motion.

  That is, as in the tights 1 in the first embodiment, the strong tightening region 5 covers the wearer's patella and extends in the length direction L of the leg from the patella to the front of the thigh and the front of the lower leg. By doing so, the straight femur 13 and the lateral vastus muscles during knee joint movement are compared with bare feet, ordinary tights that do not have a strong tightening region, and conventional tights that do not cover the patella with the strong tightening region. The muscle burden to 14 can be reduced. This is particularly useful from the viewpoint of reducing the burden of active muscles associated with “standing”.

  Further, in “standing”, the recovery force (recovery of tension) of the vertical extension (extension in the length direction L) by the strong tightening region 5 assists the rectus femoris and lateral vastus muscles, thereby reducing the muscle load. -10%. Further, in “sitting”, it is possible to assist extensible contraction of muscles and prevent rapid knee joint movement by stretching (stretching in the length direction L) resistance. Thus, the tights 1 in the first embodiment uses the dimensional change in the length direction of the body accompanying the wearer's chair sitting position, standing position, walking, or the like, so that the strong tightening region 5 is raised. The tension generated in the direction (length direction L) and its recovery force are utilized.

  Further, by not extending the strong tightening region 5 in the width direction H of the leg portion, hoop tension (circumferential stress) due to the strong tightening region 5 is not generated, and the blood flow in the leg portion is prevented from being hindered. can do.

  Further, in the tights 1 according to the first embodiment, it is possible to prevent the occurrence of skin damage such as rash due to tape adhesive or repeated use of the adhesive tape, such as when taping on bare feet. be able to.

  In the tights in which the tight tightening region 5 covers the wearer's patella and only extends in the length direction of the leg from the patella to the thigh and the lower leg, the body surface and the tights of the wearer Due to the shift, the effect of the strong tightening region 5 is reduced as compared with the case where the S-type taping is performed on the bare foot. However, in the first embodiment, the strong tightening region 5 is provided on the patella of the wearer. On the other hand, the locking portions 6 on the thigh side and the crus side are respectively locked, so that the displacement between the wearer's body surface and the tights 1 at the locking portion 6 is suppressed and tightened. The effect of the region 5 can be improved.

  Furthermore, although the veins pass through the front side of the thigh and lower leg, the veins do not pass through the front side of the patella (the veins pass through the back side of the patella). Even when No. 5 applies pressure to the wearer's patella from the front side, blood flow is not hindered at the knee joint.

  Moreover, in this 1st Embodiment, although demonstrated using the tights 1 as innerwear, the inner which goes around at least a knee joint of wearers, such as a supporter, spats, or sports tights, and is closely_contact | adhered to the cover body surface If it is a wear, the same effect can be show | played by providing the strong fastening area | region 5 and the latching | locking part 6 in a corresponding position.

It is a right view of the spats shown in FIG. 21 to 24, the same reference numerals as those in FIGS. 1 to 20 denote the same or corresponding parts, and the description thereof is omitted.
In the seventh embodiment, the strong tightening region 5 in the crotch 3a and the panty 2c is branched into two from the wearer's patella to the thigh, and from the front side of the crotch 3a to the inner side of the wearer's thigh. And the third curved portion 21d that extends to the back side of the thigh 3a and does not extend to the wearer's buttocks, and the first on the side of the panty 2c that passes from the front side of the thigh 3a through the waist of the wearer. And a fourth curved portion 21e connected to the elastic band 18a. Further, the strong tightening region 5 between the first region 8 and the hem 3d divides into two from the third region 19a on the front surface of the wearer's lower leg part and circulates around the lower leg part. It consists of a band-like fifth region 19c that is joined at the rear of the part and is connected to the hem 3d along the wearer's Achilles tendon.

Thus, the third curved portion 21d can suppress the sliding down of the inner wear. That is, when the third curved portion 21d extends to the wearer's buttocks, the third curved portion 21d, which is the strong tightening region 5, becomes a resistance to the dimensional change of the inner wear in the buttocks. In particular, since the third curved portion 21d, which is the strong tightening region 5, follows the increase in the size of the inner wear of the buttocks in “sit”, the waist of the inner wear is lowered.

  Even if the third curved portion 21d does not extend to the wearer's buttocks, the strong tightening region 5 extends from the front side of the thigh 3a to the back side of the thigh 3a through the inner side of the wearer's thigh. Therefore, tension is generated in the first region 8 around the patella in “sitting”, and the recovery force of the knitted fabric in “standing” has an effect of supporting the rectus femoris and the like. Moreover, when extending the 3rd curve part 21d under a wearer's buttocks (gutter groove part), there exists an effect of a wearer's hips-up by innerwear.

  In addition, the fourth curved portion 21e extends outside the waist of the wearer, so that the slipping of the innerwear of “sitting” is suppressed, and the strong tightening region extends from the patella to the thigh and the lower leg. The effect by 5 can be improved.

  In addition, by placing the third region and the fifth region of the strong tightening region 5 in the vicinity of the soleus muscle and the Achilles tendon of the wearer, the muscle load during walking can be reduced, and the wear due to rapid muscle extension Can prevent injury.
