Description

  The present invention relates to a bottom garment that can be expected to have a walking posture correcting effect and a shape-up effect without conscious and active exercise.

  Conventionally, for bottom clothing that fits the wearer's body, such as spats, girdles, and supporters, in addition to correcting or shaping the wearer's body shape, one that corrects the posture at rest or walking, or exercise Some are intended to improve functionality.

  Among these bottom garments, for example, a conventional bottom garment using a belt-like or belt-like fabric having a tightening force is disclosed in Patent Document 1, for example. The fit-type crotch garment proposed in Patent Document 1 has a belt-like hip pull-up portion having a tightening force, the leg portion is easy to move, has a good wearing feeling, and a hip-up function is also realized. Yes.

  Further, for example, Patent Document 2 proposes a female pelvis supporter having a belt having strong elasticity on both the front side and the back side of the wearer. In this female pelvis supporter, the elastic belt on the front side of the body extends upward from the crotch part (crotch part) and is divided into right and left at the upper part of the pubic part to support the female pelvis. And the front part pinched | interposed into the elastic belt of the body front side divided into right and left is comprised with the cloth material lacking in a stretching property. The elastic belt on the back side of the body extends upward from the crotch portion to cover the fissure, and is divided into left and right portions at the upper portion of the sacrum.

  On the other hand, if you try to stabilize your body by wearing clothing with crotch that has improved posture correction function and motor functionality, the movement of the legs will be hindered during walking or the posture during walking will not be stable enough In order to solve the problems that occur, for example, in Patent Document 3, it has a tightening force at least in the longitudinal direction, and in the worn state, from the left and right flank portions on the front side of the body or from below the crotch portion There has been proposed a crotch garment including a tightening portion having two tightening line portions extending to the left or right side abdomen or waist portion on the back side of the body or the waist.

  Hereinafter, preferred embodiments of the bottom garment of the present invention will be described in detail with reference to the drawings. In the following description, the same or corresponding parts are denoted by the same reference numerals, and redundant description may be omitted. In the following description, since the drawings are for conceptual description of the present invention, the dimensions and ratios of the components shown may be different from the actual ones.

  When walking while wearing the bottom clothing of the present embodiment shown in FIG. 1, a first tightening portion (pear-like muscle tightening portion), a second tightening portion (hamstrings muscle tightening portion), and a third tightening portion ( The gluteal muscle tightening part) can support the work of the three muscle parts (piriform muscle, hamstring muscle and gluteal muscle) in the body, and the user wearing this can walk easily and in a good posture Can do.

  FIG. 1 is a plan view showing the back side of the bottom garment 1 of the present embodiment. The bottom garment 1 of the present embodiment includes a substantially rectangular main body 2 and a tightening portion configured such that the expansion / contraction rate is lower than the expansion / contraction rate of the main body 2, and is worn by a wearer (user). It is configured to fit the body, and the tightening portion includes a first acute tightening portion (pear-like muscle tightening portion) 4 having a substantially acute triangular shape and a second tightening portion (hamstring muscle) having a substantially isosceles triangular shape. And an approximately rectangular (quadrangle) -shaped third tightening portion (a gluteal muscle tightening portion) 8. The first tightening portion 4 and the third tightening portion 8 partially overlap each other, but are stacked from the user's body side to the outside in the order of the first tightening portion 4 and the third tightening portion 8.

  Here, FIGS. 2 to 4 are views showing three muscle parts of the left leg supported on the user's body from the back when walking while wearing the bottom clothing 1 of the present embodiment. FIG. 3 is a diagram showing a striated muscle X, a hamstrings muscle Y, and a gluteus medius Z. The first tightening portion 4, the second tightening portion 6, and the third tightening portion 8 in the bottom garment 1 of the present embodiment are from the main body portion 2 in the contraction direction of the piriform muscle X, the hamstring muscle Y, and the gluteal muscle Z, respectively. Is also a portion having a low expansion / contraction rate.

  The first tightening portion 4 supports the contraction of the piriform muscle, and as shown in FIGS. 5 (a) to 5 (b), the entire leg is opened outward with the length direction of the leg as an axis. A force acts in the direction to try (external rotation), which makes internal rotation difficult (inner crotch difficult), makes it easier to move the thigh of the leg, especially on the skeleton, to the rear side, When trying to walk in the turning (inner crotch) direction, the thigh of the leg is less likely to move forward, and the knee below the leg is likely to extend forward due to inertia and inertia.

  5A and 5B are diagrams showing the positions of both feet. FIG. 5A shows a state in which lines l and m connecting the toes and heels of the left and right feet are positioned substantially in parallel, and FIG. Lines l and m connecting the toes of the foot and the heel cross each other, and the entire leg is shown to open outward with the length direction of the leg as an axis.

  The second elastic band member 6 supports the contraction of the hamstring muscle, and when walking, the body is kicked up (swinged up) with the left leg in the direction of the arrow D1, as shown in FIG. 6 (a). However, the knee joint is easy to bend and the lower knee is easy to move rearward and upward. Next, when trying to swing out the right leg forward, a force is applied to the thigh portion of the right leg in the direction of the arrow D2 so that it does not move unnecessarily upward, so that the hip joint is easily extended and bent. (Body leaning forward) is suppressed. In addition, the knee below the rear upper side is easily moved to the front side (in the direction of arrow D3) due to inertia and inertia, and the entire right leg moves forward with the knee extended. In this way, the user can walk easily.

  At this time, as described above, force acts in the directions of the arrow D2 and the arrow D3, the movement of the right leg to the front side of the thigh is suppressed, and the movement of the right leg to the front under the knee is promoted. Therefore, it is difficult for the upper body of the body to tilt forward, and as shown in FIG. 6 (b), the right leg can easily reach the ground with the knees straightened, and thus walk with good posture. Can do. By continuing the same movement as the above, followed by the left leg, right leg, left leg,..., The user can continue walking with good posture with ease.

  Further, the action of contracting the greater gluteus muscle is supported by the third tightening portion 8. The gluteus medius is a muscle that exerts stronger muscular strength than the piriform muscle and the hamstring muscle, and also has one aspect that exerts the same action as these, so the third tightening portion 8 is the first tightening portion 4 or the second tightening portion. The same function as the tightening portion 6 is also exhibited. In particular, as with the second tightening portion 6, the third tightening portion 8 applies a force to the thigh portion in the direction of the arrow D2 when trying to swing the leg forward, and the thigh portion moves upward in the front side. Therefore, the hip joint is easily extended, and its bending (forward tilt of the body) is suppressed. In addition, it is thought to support the external rotation of the legs. The user wearing the bottom garment 1 can continue to walk easily with a good posture by the functions of the first tightening portion 4, the second tightening portion 6, and the third tightening portion 8.

  Here, for easy understanding of the configuration of the bottom garment 1 of the present embodiment, FIGS. 7 to 9 show the first tightening portion (pear-like muscle tightening portion) 4 in the bottom garment 1 shown in FIG. An isosceles triangular second tightening portion (hamstrings tightening portion) 6 and a substantially rectangular (quadrangle) third tightening portion (scapular muscle tightening portion) 8 are shown individually.

  FIG. 7 is a conceptual diagram for explaining the position of the first tightening portion (pear-like muscle tightening portion) 4 in the bottom garment 1 of the present embodiment, and FIG. 8 is the first view of the bottom garment 1 of the present embodiment. It is a conceptual diagram for demonstrating the position of the 2 tightening part (hamstrings muscle tightening part) 6. FIG. FIG. 9 is a conceptual diagram for explaining the position of the third tightening portion (gluteal muscle tightening portion) 8 in the bottom garment 1 of the present embodiment. However, in FIG. 7 to FIG. 9, only the left tightening portion is shown for convenience.

  The first tightening portion 4 shown in FIG. 7 substantially corresponds to a first region extending from the side of the user's sacrum a shown in FIG. 2 to the upper edge of the femoral trochanter b (ie, the piriformis). The second tightening portion 6 shown in FIG. 8 is provided at a position substantially corresponding to a second region extending from the user's sciatic tuber c to the outer upper part and the inner upper part of the tibia d shown in FIG. 9 is a third region extending from the side of the user's sacrum a to the rough surface of the gluteal muscle of the femur e as shown in FIG. Is provided at a position substantially corresponding to (i.e., a position substantially corresponding to the greater gluteus medius).

  The first tightening portion 4, the second tightening portion 6 and the third tightening portion 8 may be arranged on the surface of the main body portion 2 by sewing or the like, and the overlapping first tightening portion 4 and third tightening portion 8 are the first tightening portions. What is necessary is just to arrange | position by sewing etc. so that the part 4 and the 3rd fastening part 8 may be laminated | stacked in order. A notch (opening) corresponding to the combination of the first tightening portion 4, the second tightening portion 6 and the third tightening portion 8 as shown in FIG. The portion 4, the second tightening portion 6, and the third tightening portion 8 may be arranged by sewing or the like.

  The first tightening portion 4 has a lower expansion / contraction rate than the main body portion 2 in the first direction from the side of the sacrum to the upper edge of the greater trochanteric trochanter (in the direction of the arrow in FIG. 7). The tightening portion 6 has a lower expansion / contraction rate than the main body portion 2 in the second direction (in the direction of the arrow in FIG. 8) from the sciatic tuberto to the center of the outer upper portion and inner upper portion of the tibia, and the third tightening portion 8 has the sacrum The expansion / contraction rate is lower than that of the main body 2 in the third direction (the direction of the arrow in FIG. 9) from the side of the body toward the rough surface of the gluteal muscle of the femur.

  More specifically, as shown in FIG. 7, the first region covered by the first tightening portion 4 includes the sacral lowest point A2 and one end of the waist opening on the vertical direction upper side (for example, about 2 to 5 cm above) the crotch center point A1. A straight line A2B connecting the point B which is approximately ¼ from the portion, and a straight line A2C1 extending from the sacral lowest point A2 toward the side edge on one end side of the waist opening and substantially orthogonal to the side edge at the point C1 A region surrounded by a straight line C1D connecting the point C1 and the other end D of the waist opening is substantially included.

  Further, as shown in FIG. 8, the second region covered by the second tightening portion 6 extends from the crotch center point A1 toward the side edge on the one end side of the waist opening and is substantially orthogonal to the side edge at the point C2. It substantially includes a region surrounded by a straight line EF and a straight line EG connecting the substantially center point E of the straight line A1C2 and both ends F and G of the leg mouth edge, and a straight line FG connecting both ends F and G of the leg mouth edge. It is out.

  The third region covered by the third tightening portion 8 includes the straight line AB, a straight line BC2 connecting the point B and the point C2, and the point C2 at the side edge on the side of the point C2 and one end of the waist opening. Are substantially included in a region surrounded by a straight line C2H connecting to a point H that is the same as or below and a straight line HA2 connecting the point H and the lowest sacrum A2.

  The point C2 shown in FIG. 7 that defines the first region covered by the first tightening portion 4 is above or below the position shown in FIG. 7 as long as it has a certain effect on the piriformis. May be.

  The point E that defines the second region covered by the second tightening portion 6 may also be above or below the position shown in FIG. 8 as long as it can exert a certain effect on the hamstring muscle. From the viewpoint of surely covering the starting point of the hamstring muscle, it is preferably located at or above the position shown in FIG. For example, the point E may be at the position of the point B.

  Further, the point B that defines the third region covered by the third tightening portion 8 may be on the right or left side of the position shown in FIG. 9 as long as it has a certain effect on the hamstring muscle. The point C2 may be above or below the position shown in FIG. 9 as long as the point C2 can exert a certain effect on the hamstring muscle. Moreover, the point H should just be located in the same edge as the point C2 in the side edge by the side of the waist opening one end part P side, for example, may be in the position of the point F.

  About the size of the bottom clothing 1 and each component of this embodiment, it can adjust suitably by a user's body shape and sex, for example, what is necessary is just to standardize and manufacture it as LL, L, M, and S dimension. In particular, the distance A1A2 from the crotch center point A1 to the sacrum lowest point A2 may be, for example, about 3 to 15 cm, and further about 5 to 10 cm, and the distance from the crotch center point A1 to the waist opening (ie, The back side crotch dimension) may be, for example, about 15 to 25 cm, and further about 18 to 22 cm.

  Here, in order to create a state of “fitting” to the body when the bottom garment 1 of the present embodiment is worn, the peripheral direction is 50% or more and 110% or less, more preferably 70, relative to the naked size of the human body. The bottom garment 1 is formed with a percentage of 95% to 95% and a length of 75% to 100%, more preferably 85% to 100%. Of course, since the size of the human body varies among individuals, the above ratio is a guide.

  The main body portion 2 of the bottom garment 1 of the present embodiment covers the main fabric portion constituting the bottom garment 1, that is, the waist and at least the thigh, and includes the first tightening portion 4, the second tightening portion 6, and the third tightening. As described above, the portion 8 is disposed at a position so as to cover at least part of or both of the piriformis, hamstrings, and gluteal muscles as described above. Thus, the main body 2, the first tightening portion 4, and the second The bottom garment 1 of the present embodiment can be manufactured by combining the fabrics constituting the tightening portion 6 and the third tightening portion 8 by sewing or knitting.

  The bottom garment 1 of this embodiment may be formed so as to cover up to the knee, below the knee, or the ankle, and the present invention is not limited to the dimensions in FIG. When covering up to the knee or ankle, these areas include the body (waist and at least the thigh), the first tightening section, the second tightening section, and the third tightening section (and additional fabric if necessary). Material). The main body portion, the first tightening portion, the second tightening portion, the third tightening portion and the like (in particular, the first tightening portion, the second tightening portion and the third tightening portion) are preferably laminated and integrated by sewing or the like. In the case of a weft knitted fabric, it can be knitted integrally.

  The material of the main body and the tightening portion (the first tightening portion, the second tightening portion, and the third tightening portion) is a so-called stretch material, for example, expansion and contraction (elongation) when a 4.9 N (500 gf) load is applied in a 5 cm width of the material. ) Regarding the rate, it is preferable that the material of the tightening portion is in the range of 5% or more and less than 30% and the material of the main body portion is in the range of 30% or more, at least in the vertical direction when the bottom clothing is used. Further, the elongation rate when 17.7 N (1800 gf) is applied in a width of 5 cm may be 30% or more and less than 80%, and the main body part may be 80% or more in the longitudinal direction at least in the case of bottom clothing. preferable.

In order to obtain such stretch characteristics of each portion, as will be described later, for example, when an elastic yarn is used as a constituent yarn of a knitted fabric or a woven fabric, the following means can be taken as an example.
(1) The elastic yarn has a higher proportion of elastic yarn than the main body.
(2) The tightening portion is made thicker than the main body portion.
(3) Compared to the main body portion, the tightening portion has a higher warp and / or weft density in the case of a woven fabric and a higher knitting density in the case of a knitted fabric.
(4) The tension portion is made of woven fabric or knitted fabric by increasing the tension of the elastic yarn as compared with the main body portion.
(5) A fabric or a knitted fabric is manufactured in the tightening portion by increasing the thickness of the fabric compared to the main body portion.

  As the stretch material, fabrics such as a 2-way stretch knitted fabric and a 2-way stretch woven fabric that expand and contract in the vertical direction and the horizontal direction can be used. The two-way stretch knitted fabric or woven fabric may include polyester fiber yarns and elastic yarns as main component constituting yarns, or nylon fiber yarns and elastic yarns as main component constituting yarns. As another configuration, cotton (cotton) and elastic yarn may be used as the main component constituting yarn. The main component constituting yarn means a component constituting yarn that is 80% by weight or more in total. The use of polyester fiber yarn is preferable from the viewpoint that it is easy to dry even if sweated, and the use of nylon fiber yarn is preferable from the point that a knitted fabric with a soft touch is obtained.

  The knitted or woven fabric may have any structure. The woven fabric may be a plain weave, a diagonal weave, and a satin weave, which are generally known, and a changed weave. Further, a knitted fabric knitted by a Russell warp knitting machine generally known as a knitted fabric, a knitted fabric knitted by a tricot warp knitting machine, a knitted fabric knitted by a knit weft knitting machine, or the like may be used.

  Examples of the knitted fabric include a knitted fabric having a half structure knitted by a tricot warp knitting machine and a knitted fabric having a power net structure knitted by a Russell warp knitting machine. As the knitted weft knitted fabric, any organization such as a flat knitting (tengu knitting), a rubber knitting, a pearl knitting, and a smooth knitting (double-side knitting) may be used. The knitted fabric knitted by the knit weft knitting machine may be a knitted fabric knitted by a circular knitting machine or a flat knitting machine. In the case of the weft knit, the first tightening portion, the second tightening portion, and the third tightening portion can be laminated and integrally knitted without requiring sewing. For example, a knitted product without sewing can be manufactured by knitting the waist and both legs at the same time using an apparatus called “FIRST-X” of a flat knitting machine (Shimae Seisakusho).

  In addition, it is a device called “seamless body inner knitting machine” under full computer control of Santoni in Italy, and a combination of strong and weak tightening materials is seamlessly knitted into a cylinder, and the lower abdomen and legs It is also possible.

  The woven fabric or knitted fabric preferably uses at least a part of elastic yarn having elasticity such as polyurethane yarn. The elastic yarn is preferably at least one selected from a polyurethane elastic yarn and a polyester elastic yarn. This is because it is highly stretchable and suitable for sports clothing. The elastic yarn may be either a bare yarn (bare yarn) or a covered yarn whose surface is coated with polyester fiber or nylon fiber.

  Fabrics using high crimped false twisted yarns such as polyester and nylon that have been subjected to high crimped false twisting for at least part or all of the fabric can also be used. Further, it is also possible to simply use a plurality of the knits having elasticity as described above. Furthermore, the stretchable knit fabric is laminated into two layers to form a two-layer laminate fabric, and the stretchable polyurethane sheet is sandwiched between the stretchable knit fabric and laminated into three layers. A layer laminate fabric can also be used.

  Next, as a method of giving the fabric material a “strong” and “tight” tightening force to form a tightening portion (strong tightening material) and a main body portion (weak tightening material), for example, polyurethane yarn, highly crimped false twisted yarn (hereinafter referred to as “high crimped yarn”) , "Stretchable yarn"), and the mixing ratio of "large and small" allows each fabric material to have a "strength" tightening force. As a method of changing the blend ratio, changing the thickness of the stretch yarn to “thin and thin” gives the blend ratio “large” or “small”. There is a way to get a “large” or “small” mix ratio. It is also possible to change the knitting density to “sparse / dense” when the mixing ratio of the stretchable yarn is constant. In addition, using a fabric with different types of stretch yarns, using a laminated fabric and a non-laminated fabric, or changing the number of layers of the same fabric will also give the fabric a “strength” tightening force. It is possible to have it.

  The “strength” tightening force of the strong tightening material and the weak tightening material can be confirmed by the magnitude of the stretch rate of the fabric at a constant load. That is, a fabric having a strong tightening force has a low elongation rate, and a fabric having a weak tightening force has a high elongation rate. The “tightening force” in the present invention refers to the resistance of a material to elongation.

  Elongation rate representing stretchability and tightening force was measured using a TENSILON universal type tensile tester (UTM-III-200, manufactured by Toyo Baldwin), with a tensile strength of 20 cm / min, and the size of the sample fabric was 5 cm wide. , And can be measured as a length of 30 cm and a gripping interval of 20 cm. The weight at the time of measuring the tightening force is 4.9 N (500 gf), the weight at the time of measuring the stretch property is 17.7 N (1800 gf), and the measurement may be made in the background direction of the fabric material.

  The bottom garment of this embodiment can also be formed by integrating the strong tightening material and the weak tightening material by sewing or bonding. Examples of the sewing method include a method of sewing with a sewing machine that forms stitches such as main stitching, chain stitching, one-needle overlock, two-needle overlock, and flat seam. It is not limited to these. However, it is desirable to adopt a one-needle overlock, a two-sewing overlock, and a flat seamer that have a stretch property and are less likely to cause discomfort when worn.

  As the bonding method, paste two types of fabrics (members) that you want to integrate, melt them with heat, and paste them with a heat-meltable seam tape made of resin, such as polyurethane or silicone, which penetrates and solidifies after cooling. Although there is a thermocompression bonding method in which the fabric can be bonded by sandwiching between the fabrics and heat-pressing, it is desirable to provide a stretch property similar to sewing so as to eliminate the uncomfortable feeling at the time of wearing.

  Although the representative embodiments of the present invention have been described above, various design changes can be made within the scope of the technical idea of the present invention. As long as the technical idea of the present invention is used, the contents of the design change are included in the scope of the present invention. That is, in short, all bottom clothing having a pear-like muscle tightening portion, a hamstring muscle tightening portion, and a gluteal muscle tightening portion are all included in the present invention.

  For example, the leg mouth edge part below the crotch center point A1 in FIG. 1 is located considerably above the knee of the user, but may be closer to the knee or cover the knee longer. FIG. 10 is a plan view showing the back side of a modified example of the bottom garment 1 shown in FIG. Moreover, as shown in FIG. 10, you may arrange | position the pad (non-stretchable member (fabric)) 10 with a low expansion / contraction rate in the position corresponding to a sacrum. The shape of the pad having a low expansion / contraction rate may be a substantially inverted triangle corresponding to the sacrum, but may be a rectangle such as a trapezoid (either the upper side or the lower side may be longer). If such a pad is arranged, the pad portion can serve as a fulcrum, so that the first tightening portion 4, the second tightening portion 6 and the third tightening portion 8 are concentrated on the piriform muscle, the hamstrings muscle and the greater gluteus muscle, respectively. Easy to act.

  Moreover, in the said embodiment, the 1st fastening part 4 and the 3rd fastening part 8 have overlapped partially, and are laminated | stacked toward the outer side in order of the 1st fastening part 4 and the 3rd fastening part 8 from a user's body side. However, for example, when the upper end of the second tightening portion 6 extends to the waist opening and overlaps the first tightening portion 4 and the third tightening portion 8, the first tightening portion 4, from the user's body side, It is preferable to adopt a configuration in which the second tightening portion 6 and the third tightening portion 8 are laminated in this order toward the outside. Of course, the stacking order may be arbitrary.

  Moreover, in the said embodiment, the main-body part 2 thru | or the bottom garment 1 are substantially rectangular, the width | variety by the side of a waist opening (PQ in FIG. 7) is a little shorter than the width | variety by the side of a leg mouth, and a side edge is slightly refracted. However, the bottom garment of the present invention is not limited to such a form. For example, the side edge may be linear or curved.

The bottom garment of the present invention can be applied to tights (half or long), spats (half or long), girdle, stockings, etc. and is suitable for walking, but also various sports such as athletics, jogging, mountain climbing and hiking. It is also suitable for exercise. The bottom garment of the present invention can also be provided inside the lower garment as an inner integrated with various garments such as a jersey, slacks, and trousers.
