Description

  The present invention relates to apparel such as girdle and spats made of elastic knitted fabric, and particularly to apparel that can obtain the effect of strengthening muscles simply by wearing it.

  For example, girdle, spats, and other clothing that covers from the waist to the thigh are generally configured to fit the body by an elastic knitted fabric knitted by a circular knitting machine.

  Due to the recent increase in health consciousness, in order to strengthen muscle strength of the lower back and left and right legs, when performing strength strengthening training that applies a relatively large load, it is accompanied by a considerable mental and physical burden. There is also a risk of muscular strength training that hurts the hips and knee joints.

  Therefore, in the clothes such as the girdle and spats, the limbs (mainly) from the lower back (main) during normal life movements, including normal walking, going up and down stairs, bending and stretching, etc. In addition, clothing that can moderately apply a load to a portion extending to the thigh) and can obtain an effect of strengthening muscle strength has been proposed.

  For example, in Patent Document 1 below, a laterally stretchable portion that has a higher stretchability in the left-right direction than the up-down direction, continuously from the waist to the thigh on the front left and right and the left and right rear, It has been shown that by suppressing the expansion of the lumbar and thigh muscle abdominal areas, the muscle strength of the lumbar region and lower limbs can be improved by applying a moderate load during muscle contraction.

Further, in Patent Document 2, when the thigh is lifted, a predetermined region on the back side corresponding to a portion where the amount of skin stretch in the buttocks and the thigh is large is higher than the region other than the region. It has been shown that by providing a highly elastic portion having a high elastic modulus, a predetermined load can be applied to the psoas major muscle, and the effect of strengthening the muscular strength is obtained.

  By the way, in the case of the apparel of Patent Document 1, by using a material having high elasticity in one direction in the vertical direction or the horizontal direction, the elasticity in the horizontal direction with respect to the vertical direction is increased at a predetermined portion. Therefore, the usage form of the material itself is changed. Therefore, in manufacturing, a sewing process for connecting the materials of the vertical stretchable part and the horizontal stretchable part is required, which takes time, increases man-hours, reduces productivity, and increases costs. Moreover, because of the presence of the sewing portion, the feeling of wearing and the appearance when worn are also impaired.

  Also, in the case of the apparel of Patent Document 2, the high elastic portion is formed by superposing two types of elastic fabrics, and therefore requires a sewing process for fabric stitching in manufacturing, and requires separate pattern paper. It is also necessary to make the manufacturing process, and it takes time and labor to manufacture, and the productivity is low and the cost is high. Moreover, due to the double structure, there is a problem that the drying time after washing becomes long and the finished state becomes unstable. Furthermore, since it has a double structure and a sewing part, it will also impair a feeling of wear and the external appearance at the time of wear.

  The present invention has been made in view of the above, and as an apparel such as a girdle or spats that can obtain an effect of strengthening muscle strength, it is made of a stretch knitted fabric that is integrally knitted. By utilizing the difference in stretchability due to changes, it is possible to apply an appropriate load to the muscles of the part from the waist to the thigh, and it can be worn without impairing the appearance. Alternatively, the present invention provides clothing that can improve the productivity of seed garments without the need for bonding.

  In order to solve the above-mentioned problems, the present invention is a garment comprising a stretch knitted fabric that is integrally knitted, covering the thighs of the left and right lower limbs from the waist, and the hips from the waist upper end to the left and right sides. A belt-like stretchable part that is difficult to stretch from the base fabric part is formed by a change in the knitting structure continuously through the thigh.

  According to the above garments, since there are no double fabric parts or sewing parts in the wearing state, the feeling of wearing is good and the appearance is not impaired. Moreover, in the movement of the wearer's walking, stairs going up and down, and bending and stretching, the stretch is suppressed by the stretchable belt-like stretchable part, so that each muscle in the region extending from the waist to the thighs of the left and right lower limbs A moderate load can be given, and the effect of strengthening the wearer's muscular strength can be exhibited just by wearing. In particular, when the belt-like stretchable part is formed continuously from the gluteal muscle part of the back of the lumbar region through the gluteus medius and along the biceps femoris and semi-tendonoid muscle parts, strengthening of these muscle strengths Can be made particularly suitable.

  In the garment, the hardly stretchable belt-like stretchable part includes a first stretchable part extending from the upper end of the waist to the lower end of the hip part, and a second extending continuously from the first stretchable part to the lower end of the thigh. It is preferable that the stretch rate of the first stretchable portion is smaller than the stretch rate of the base fabric portion and larger than the stretch rate of the second stretchable portion.

  As a result, the first and second stretchable portions of the hardly stretchable belt-like stretchable portion are less likely to be stretched than the base fabric portion, and the stretch associated with movement such as walking and bending / stretching is suppressed. By acting, for example, a moderate load is applied to the gluteus gluteal muscle, the greater gluteus muscle, etc. above the hip portion by the first stretchable portion, and the rear muscles of the thigh, that is, the thigh by the second stretchable portion. A moderate load can be applied to the biceps and semi-tendon-like muscles to effectively strengthen the muscles. In addition, since the first stretchable part has a larger elongation rate than the second stretchable part and is easy to stretch, the first stretchable part does not excessively bite into the wearer's hip part. The wearing state which does not impair the external appearance can be obtained.

  Therefore, the first stretchable part having a difference in elongation rate as described above passes from the gluteal muscle part to the greater gluteus muscle part on the back surface of the lumbar region, and the second stretchable part includes the biceps femoris muscle and the semi-tendon. Those formed along the portion of the striated muscle are particularly preferable.

  In the garment, the elongation rate of the first stretchable part is 1/2 to 4/5 of the stretch rate of the base fabric part, and the stretch rate of the second stretchable part is 1 of the stretch rate of the base fabric part. / 5 to 1/2.

  That is, when the elongation rate of the first stretchable portion is larger than the above, there is almost no difference from the base fabric portion, the load on the muscles such as the gluteus medius and the gluteal muscle is reduced, and the effect of strengthening the muscular strength Will not be expected. In addition, when the elongation ratio of the first stretchable portion is smaller than the above, the effect of suppressing the stretch becomes large, and the biting into the hip portion becomes large in the wearing state, and the appearance may be impaired. Further, when the elongation rate of the second stretchable portion is smaller than the above, the effect of suppressing the stretch becomes too large, and the feeling of wearing becomes worse, and when the stretch rate of the second stretchable portion is larger than the above, The effect of suppressing elongation necessary for applying the required load to the muscles such as the biceps femoris and semi-tendonoid muscles on the back of the head cannot be obtained. Therefore, it is preferable to set the difference in elongation rate between the base fabric portion, the first stretchable portion, and the second stretchable portion as described above.

  In the garment, it is preferable that the first stretchable portion is curved along the outside of the hip portion so as to avoid the top portion of the hip portion. Thereby, it can prevent that the said 1st expansion-contraction part in the said non-extensible strip | belt-shaped expansion-contraction part digs deeply into a wearer's hip part, and an external appearance becomes unnatural, and it can wear well.

  In the apparel, it is preferable that a width of the hardly stretchable belt-like stretchable portion is 20 to 70% of a width of a rear surface of the thigh.

  As described above, according to the apparel of the present invention, in the left and right parts of the back body, the belt-like stretchable part that is less stretchable than the base fabric part is continuous from the waist upper part through the hip part to the lower part of the thigh. Since it is formed by changes in the knitting structure, it is appropriate for each muscle in the part from the waist to the thigh due to the inextensible belt-like stretchable part in the normal movement of the wearer walking and bending and stretching. It is possible to exert the effect of strengthening muscles by simply wearing them without performing special strength training.

  In particular, the belt-shaped stretchable part is composed of a first stretchable part of the hip part and a second stretchable part of the thigh, and the stretch rate of the first stretchable part is smaller than the stretchability of the base fabric part. And when the extension rate of the second stretchable part is set to be greater than the extension rate of the second stretchable part, the first and second stretchable parts cause the gluteus gluteal muscle in the upper part of the hip part or the greater gluteus muscle in the hip part and the thigh. A suitable load can be applied to the biceps femoris muscle, the semi-tendon-like muscle, etc. on the rear surface of the head, and the muscular strength can be effectively strengthened. In addition to this, the first stretchable part does not excessively bite into the wearer's hip part, and the effect of strengthening muscles can be obtained while maintaining a good wearing state that does not impair the appearance.

  Moreover, in the case of the apparel of the present invention, in the stretch knitted fabric knitted integrally, the stretchable belt-like stretchable portion, particularly the first and second stretchable portions, are stretched by changing the knitting structure. Therefore, it can be easily manufactured by changing the knitting structure on a program by a circular knitting machine, for example, and a sewing process and a person for sewing can be made unnecessary. In addition, the manufacturing time can be greatly shortened and the material can be reduced compared to the case where different fabrics are connected or bonded together, so that it can be manufactured at low cost and the productivity can be increased.

  Also, unlike the case where a separate fabric is laminated to make a double structure, the drying process after washing can be performed in a short time, the finished state by drying is stabilized, the sewing part and the double fabric part Since it does not have, there is an effect that the feeling of wearing is good and the appearance is also good.

  Next, embodiments of the present invention will be described based on examples shown in the drawings. In addition, this invention is not limited to an Example.

  FIG. 1 is a schematic front view showing the front side of the garment of the present invention, and FIG. 2 is a schematic rear view showing the rear side of the same. FIG. 3 is a schematic perspective view of the rear side of the wearing state, and FIG. 4 is an explanatory view schematically showing the configuration state of main muscles in a portion extending from the waist of the human body to the thighs of the left and right lower limbs.

  The garment 1 of the illustrated embodiment illustrates a case of a girdle (particularly, a long girdle) that covers the lower body, in particular, the waist and the thighs of the left and right lower limbs. This garment 1 is made of a stretch knitted fabric knitted integrally by a circular knitting machine, and the left and right thighs 3 and 3 that branch from the waist 2 and the lower back to the fork and cover the knees of the thigh are integrated. Formed. In the figure, 4 is a waist part integrally formed at the upper end of the waist part 2, 5 is a hip part, 6 is a waist side part, and 7 is an abdomen on the front side (front viewing side).

  As shown in FIG. 2, the garment 1 has a left and right parts 1a and 1a which are divided at the center of the lumbar part on the rear side (the back side), from the substantially central positions of the left and right parts 1a and 1a at the upper end of the lumbar part 2. The stretchable belt-like stretchable part 10 which is continuously stretched from the top part 5a of the part 5 to the lower end parts 3a, 3a of the thighs 3 and 3 in the left and right lower limbs and whose extensibility is kept low is It is formed so as to have different extensibility by changing the knitting structure. The hardly stretchable belt-like stretchable portion 10 is more structured than a base fabric portion a having inherent stretchability, for example, a base fabric portion a such as a central portion of the hip portion 5 or a portion that wraps around from the waistside portion 6 to the front side. In other words, it is a portion where the extensibility is suppressed to a low level.

  The hardly stretchable belt-like stretchable part 10 has a hip on the back of the lumbar depending on the constitutional state of the muscles extending from the waist 22 on the back side of the human body and the thighs 23, 23 of the left and right lower limbs as schematically shown in FIG. Formed continuously in the longitudinal direction (vertical direction) along the portion of the biceps femoris 26 and the semi-tendonoid muscle 27 on the back of the thigh from the part of the gluteus medius muscle 24 existing on the upper part of the body. Has been.

  In the case of the figure, the hardly stretchable belt-like stretchable part 10 is continuous from the first stretchable part 11 extending from the upper end of the waist part 2 to the hip line part below the hip part 5 and the first stretchable part 11. The second stretchable portion 12 reaching the lower end portion 3a of the rear surface of the thigh 3, and the stretch rate of the first stretchable portion 11 is the stretch rate of the base fabric portion a due to the change in the knitting structure on the knitting. It is set to be smaller and larger than the expansion rate of the second stretchable part 12. In other words, the first stretchable portion 11 is formed to have an intermediate stretch rate between the base fabric portion a and the second stretchable portion 12. The first stretchable part 11 passes from the middle gluteus medius muscle 24 through the greater gluteus medius muscle 25, and the second stretchable part 12 extends vertically along the biceps femoris 26 and semi-tendonoid muscle 27 parts. Is formed in the direction.

  The first stretchable part 11 may be substantially linear in the vertical direction, but in the case of the figure, along the outer side of the hip part 5 so as to avoid the top part 5a of the hip part 5. Thus, the first stretchable part 11 having low extensibility can avoid the top part 5a and the vicinity thereof, and can ensure the swelling of the hip part 5 in a favorable manner.

  The extent of the stretchability of the belt-like stretchable portion 10 with respect to the base fabric portion a is 1/5 to 4 as the overall elongation rate of the base fabric portion a in consideration of the degree of load on the wearer. / 5. At this time, the thigh 3 can increase the tightening force by suppressing the extension of the belt-like stretchable part 10 and apply a relatively large load, but the hip part 5 has the tightening force by suppressing the extension of the belt-like stretchable part 10. When it becomes too strong, biting into the hip portion occurs in the wearing state, and the appearance is impaired. Therefore, as described above, the belt-like stretchable portion 10 is divided into the first stretchable portion 11 along the muscle of the hip portion 5 and the second stretchable portion 12 along the thigh muscle, and The stretch rate of the first stretchable part 11 is 1/2 to 4/5 of the stretch rate of the base fabric part a, and the stretch rate of the second stretchable part 12 is 1 / fold of the stretch rate of the base fabric part a. Set to 5 to 1/2, the second stretchable portion 12 can give a load suitable for strengthening muscle strength, and the first stretchable portion 11 does not become excessively tightened due to suppression of elongation. It is desirable to make a difference in the extensibility of each part. In particular, it is preferable to set the ratio of the elongation ratios of the respective constituent parts as base fabric portion a: first stretchable portion 11: second stretchable portion 12≈3: 2: 1.

  For example, when the elongation ratio of the base fabric portion a is approximately 110%, the elongation ratio of the first stretchable portion 11 is approximately 70%, the stretchability rate of the second stretchable portion 12 is approximately 35%, and the stretch rate of each portion. The base fabric portion: first stretchable portion: second stretchable portion≈3: 2: 1 is set.

  In addition, the said elongation rate is an elongation rate measured by the constant load method of JISL1018, hold | grips the both ends of the test cloth of length 7.6cm, and width 4cm at a fixed space | interval. This is the rate of elongation when stretched under a load, that is, a load of 3.92 N (400 gf).

  In order to change the knitting structure so as to make a difference in the elongation ratio of the first and second stretchable portions 11 and 12 of the belt-like stretchable portion 10 with respect to the base fabric portion a, the knitting interval and knitting are skipped on the knitting. Change the number appropriately. Thereby, a difference can be given to the expansion | extension rate of each part as mentioned above.

  The widths of the first elastic part 11 and the second elastic part 12 of the belt-like elastic part 10 are preferably set in the range of 20 to 70% with respect to the width of the rear surface of the thigh 3, particularly It is preferable to set the width to about 1/2 of the width of the thigh 3. That is, if the width of the belt-like stretchable part 10 becomes too narrow, the feeling of wear and the appearance when worn may be impaired. Conversely, if the width becomes too large, the load due to the suppression of elongation increases. In some cases, it is preferable to set the width within the above range.

  In addition, the said width | variety is an average width | variety in the full length of each 1st and 2nd expansion-contraction part 11 and 12, a width | variety may change a little in a length direction, and said 1st and 2nd There is a case where the shape of each of the stretchable parts 11 and 12 changes in the length direction (longitudinal direction). Furthermore, as the first and second stretchable portions 11 and 12 of the left and right portions 1a and 1a, narrow stretchable stretch bands having a small width can be formed in a double row. In this case, the full width of the double row is set as described above.

  In the case of the garment 1 of the embodiment shown in the drawing, the left and right portions 1a, 1a on the rear surface side are continuously stretched from a part of the first stretchable portion 11 of the stretchable belt-like stretchable portion 10, and the waist side portion is rotated to the front side. Further, as shown in FIG. 1, a non-extensible belt-like portion 15 that is bent downward and extends substantially along the sewing muscle (not shown) on the front surface of the thigh to the lower end portion of the thigh 3 is integrally formed. Yes. Further, the abdomen 7 is formed with an inverted triangular portion 16 having the same difficulty as described above and strong clamping force. These band-like portion 15 and inverted triangular portion 16 are also formed so as to make the extensibility different from the base fabric portion a by changing the knitting structure.

  The garment 1 having the above-described configuration is formed of a stretch knitted fabric that is integrally knitted. The stretchable knitted stretchable portion 10, particularly the first and second stretchable portions 11, 12 are changed in knitting structure. Can be formed with different elongation rates, for example, can be easily manufactured by changing the knitting structure on the program by a circular knitting machine, making it unnecessary to have a sewing process and sewing personnel, There is no need to connect and paste different fabrics, greatly reducing manufacturing time. In addition, it is not necessary to prepare a separate paper pattern or prepare a separate dough, and the material can be reduced, so that it can be manufactured at a low cost and the productivity can be increased. In addition, unlike the case where another fabric is bonded to form a double structure, the drying process after washing can be performed in a short time, and the finished state by drying is also stabilized.

  And the said clothing 1 is worn in the state which the whole clothing consisting of a stretchable knitted fabric extended to some extent, In this wearing state, although fastening force will act by the said expansion | extension, of the clothing 1 of this invention In this case, since there are no double fabric parts or sewing parts, the feeling of wearing is good and there is no risk of damaging the appearance. In the left and right parts 1a and 1a, the tightening force is partially increased by the effect of suppressing the extension of the part of the stretchable part 10 which is difficult to stretch provided continuously from the upper end of the waist part 2 to the thigh part 3, thereby the waist part. Appropriate loads can be applied to the muscles on the back side of the portion extending from 2 to the thigh 3, and the effect of strengthening the muscular strength can be exhibited.

  In particular, in the belt-like stretchable part 10, the stretchability of the first stretchable part 11 along the hip part 5 and the stretchability of the second stretchable part 12 along the thigh is made different, for example, the stretch rate of each component part. The first stretchable part 11 is continuous from the upper end of the waist 2 by setting the ratio to the base fabric part a: the first stretchable part 11: the second stretchable part 12≈3: 2: 1. As a result, the effect of strengthening the muscular strength can be further enhanced, and the first stretchable part 11 does not bite into the wearer's hip part 5, and a good appearance that does not impair the appearance can be obtained. it can.

  In the above embodiment, the garment 1 is a girdle that covers from the waist to the upper knee of the thigh. In addition to the pants-shaped spats, the left and right thighs It can also be implemented in long-type spats where 3 and 3 extend below the knee.

  INDUSTRIAL APPLICATION This invention can be utilized suitably for clothes, such as a girdle and spats which consist of a stretch knitted fabric.
