Description

[Technical field]

[0001] The present invention relates to a garment that is worn in a state where it fits closely around the lower body of a wearer, and prevents twisting of the lower limbs when crouching while increasing the walking stride. [Background technology]

[0002] Patent Document 1 discloses sportswear with a rotation function, characterized in that the lower garment is made of a stretchy fabric material that covers at least the area from near the waist to near the crotch, the lower garment consisting of a main body portion with relatively low elasticity and a stretch portion with stronger elasticity, the stretch portions being configured so that a spiral line starting at approximately the center near the top of the hip bone on the front side forms a V-shape, passing through the left and right body portions respectively, and terminating near the inside of both buttock grooves on the back side in an inverted V-shape, thereby providing an internal rotation function.

[0003] Patent Document 2 discloses legwear that covers at least the lower leg, comprising a band-shaped first lower leg tightening portion that is formed so as to extend from a first side surface of the upper end of the tibia or the upper end of the fibula, passing in order over the anterior surfaces of the tibia and fibula and the posterior surfaces of the tibia and fibula, to a second side surface of the lower end of the tibia or the lower end of the fibula, wherein when the first side surface is the medial side surface of the upper end of the tibia, the second side surface is the medial side surface of the lower end of the tibia, and when the first side surface is the lateral side surface of the upper end of the fibula, the second side surface is the lateral side surface of the lower end of the fibula.

[0004] [Patent Document 1] JP 2008-138322 A [Patent Document 2] JP 2017-115256 A Summary of the Invention [Problem to be solved by the invention]

[0005] Generally, when walking or running, one foot is put forward alternately, but when one foot is put forward, one side of the pelvis moves forward more than the other, so when trying to walk with the toes facing forward, the hip joint on one side rotates outward and the hip joint on the other side rotates inward. If the internal rotation of the hip joint on the other side is restricted, it becomes difficult for the pelvis on one side to move forward, and the stride becomes narrower. On the other hand, when bending the legs, such as when crouching or landing after jumping, the hip joint rotates inward and the knee moves inward, which is a problem especially in women, making the knee more susceptible to injury.

[0006] The invention described in Patent Document 1 is a technology that consists of a main body section with relatively weak elasticity and a stretch section with stronger elasticity, in which the force that moves the fabric and returns it to its original shape serves as an internal rotation or external rotation function. However, there is a problem in that the force that strongly inhibits internal rotation at the hip joint is weak, making it difficult to inhibit internal rotation of the thigh.

[0007] The invention in Patent Document 2 is a technology to prevent excessive rotation of the knee, but since a band is wrapped around the thigh but not around the hip joint, it is difficult to prevent the internal rotation of the femur relative to the pelvis. Therefore, there is a problem in that it is difficult to prevent the knee from rotating inward and to straighten the toes.

[0008] The present invention was devised in light of these problems, and its objective is to provide clothing that prevents twisting of the lower limbs when squatting while increasing walking stride length by encouraging internal rotation with hip extension on the pushing off side (the other side) when walking and preventing internal rotation with hip flexion when squatting. [Means for solving the problem]

[0009] The garment described in claim 1 is a garment that is worn in a state of almost intimate contact with the surface of the wearer, and is made up of at least two belt-shaped strong tightening fabrics having a strong tightening force and a tightening part having a tightening force that prevents the upper and lower ends of the strong tightening fabrics from slipping off the surface of the wearer. The strong tightening fabric is connected at its upper end to the tightening part of the back body, passes through a portion corresponding to the lower part of the greater trochanter on the lateral side, passes through the front of the thigh, and is connected at its lower end to the tightening part at approximately the center in the longitudinal direction of the inner thigh. The garment has a first strong tightening portion arranged in a spiral shape, and a second strong tightening portion arranged in a spiral shape, the upper end of which is connected to the tightening tightening portion of the front body, passing through the front of the hip joint, passing through a part corresponding to the lower part of the lateral greater trochanter, passing through the rear surface of the thigh, and the lower end of which is connected to the tightening tightening portion at approximately the center in the longitudinal direction of the inner thigh, wherein the first strong tightening portion and the second strong tightening portion are cross-connected at a part corresponding to the lower front of the greater trochanter, and the lower ends are connected or adjacent to each other at approximately the center in the longitudinal direction of the inner thigh.

[0010] The garment described in claim 2 is characterized in that, in claim 1, the tightening portion is a first form comprising a waist tightening portion connected to the upper ends of the first strong tightening portion and the second strong tightening portion and capable of being tightened around the waist, and an elastic base fabric sewn or bonded to the first strong tightening portion and the second strong tightening portion, which is worn in a state of almost intimate contact with the surface of the wearer corresponding to at least the range from the waist tightening portion to the lower ends of the first strong tightening portion and the second strong tightening portion; or a second form comprising a waist tightening portion capable of being tightened around the waist and to which the upper ends of the first strong tightening portion and the second strong tightening portion are connected, and left and right ring-shaped thigh tightening portions having a tightening force capable of being tightened around the thighs and to which the lower ends of the first strong tightening portion and the second strong tightening portion are connected.

[0011] The garment described in claim 3 is characterized in that, in claim 1 or 2, the belt-shaped strong tightening fabric has a tightening force in the longitudinal direction that affects the internal and external rotation movement of the femur when the strong tightening fabric is tensed. Effect of the Invention

[0012] The present invention was conceived with the aim of preventing twisting of the lower limbs when squatting by encouraging internal rotation with hip extension on the pushing-off side (other side) of walking, thereby expanding the range of walking, while preventing internal rotation with hip flexion when squatting.

[0013] In the garment according to claim 1 or 2 of the present invention, the upper ends of both the first and second strong tightening parts are connected to a waist tightening part that hardly stretches when walking or running, and are connected in a generally X-shaped cross shape at a site corresponding to the lower front of the greater trochanter, so that when the hip joint is extended when pushing off while walking, the second strong tightening part tenses up, causing the hip joint to rotate internally, providing a first effect. Also, when the hip joint is flexed, the first strong tightening part tenses up, preventing internal rotation of the hip joint, providing a second effect.

[0014] The first effect induces internal rotation of the hip joint when pushing off, and the pelvis on the swinging side moves forward, resulting in a wider stride and faster walking speed. The second effect also prevents knee injuries by allowing the user to land straight without bending the knee inward when landing or crouching.

[0015] The garment described in claim 3 has the advantage that the strong tightening force of the belt-shaped first strong tightening portion and second strong tightening portion is only in the longitudinal direction, so the restricting direction is narrowed, thereby increasing the restricting effect.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] As shown in FIG. 7 , the skeleton of the lower limbs includes a pelvis 20, a femur 12, a tibia 32, a fibula 33, etc., with a hip joint 10 at the junction of the pelvis 20 and the femur 12, a knee joint 30 at the junction of the femur 12 and the tibia 32, a tibiofibular joint at the junction of the tibia 32 and the fibula 33, and an ankle joint 31 at the junction of the lower ends of the tibia 32 and the fibula 33.

[0018] As shown in Figures 7, 8, and 9, the hip joint 10 is a ball-and-socket joint formed by the combination of the femoral head 13 of the femur 12 and the acetabulum 21 of the pelvis 20, and moves in six major directions: flexion, extension, internal rotation, external rotation, adduction, and abduction.

[0019] The clothing 1 of the present invention is an invention that affects the hip joint 10 during walking or running, thereby promoting internal or external rotation of the femur 12, and is suitable for movements that involve repeated flexion and extension of the hip joint 10, similar to walking and running, and can be used as clothing for a variety of purposes, such as sports clothing for track and field, freestyle swimming, speed skating, etc., as well as general lifestyle clothing for everyday life and work.

[0020] The garments 1 of the present invention include spats-type garments 1A having a base fabric 6, as shown in Figures 1, 3, 4 and 13, and belt-type garments 1B not having a base fabric 6, as shown in Figures 2, 5 and 6. The spats-type garments 1A include spats-type garments 1Aa not having thigh tightening portions 5, as shown in Figures 1, 3 and 4, and spats-type garments 1Ab having thigh tightening portions 5, as shown in Figure 13.

[0021] As shown in Figs. 1 to 6 and 13, the garment 1 of the present invention is made up of at least two belt-shaped strong tightening fabrics having a strong tightening force, and a tightening part 8 having a tightening force that prevents the upper and lower ends of the strong tightening fabrics from slipping off the wearer's surface, and is worn in a state of being in close contact with the surface of a wearer 80. The strong tightening fabric is connected at its upper end to the tightening part 8 of the back body, passes through a portion corresponding to the lower vicinity of the greater trochanter 11 on the lateral side, passes through the front of the thigh 18, and is connected at its lower end to the tightening part 8 at approximately the center in the longitudinal direction of the inner side of the thigh 18. and a second strong tightening portion 4 arranged in a spiral, the upper end of which is connected to the tightening tightening portion 8 of the front body, passing through the front of the hip joint 10, passing through a portion corresponding to the lower part of the lateral greater trochanter 11, passing through the rear surface of the thigh 18, and the lower end of which is connected to the tightening tightening portion 8 at approximately the center in the longitudinal direction of the inside of the thigh 18, the first strong tightening portion 3 and the second strong tightening portion 4 are intersectingly connected at a portion corresponding to the lower front of the greater trochanter 11, and the lower ends are connected or adjacent to each other at approximately the center in the longitudinal direction of the inside of the thigh 18.

[0022] The tightening portion 8 has a first form, as shown in FIG. 1 or FIG. 13, which is provided with a waist tightening portion 2 that can be tightened around the waist and is connected to the upper ends of the first strong tightening portion 3 and the second strong tightening portion 4, and a base fabric 6 having elasticity sewn or bonded to the first strong tightening portion 3 and the second strong tightening portion 4, which is worn in a state of almost close contact with the surface of the wearer 80 corresponding to at least the range from the waist tightening portion 2 to the lower ends of the first strong tightening portion 3 and the second strong tightening portion 4; or a second form, as shown in FIG. 2, which is provided with a waist tightening portion 2 that can be tightened around the waist and to which the upper ends of the first strong tightening portion 3 and the second strong tightening portion 4 are connected, and ring-shaped left and right thigh tightening portions 5 having a tightening force that can be tightened around the thighs 18 and to which the lower ends of the first strong tightening portion 3 and the second strong tightening portion 4 are connected.

[0023] Furthermore, the first form includes a first form A consisting of the waist tightening portion 2 and the base fabric 6, as shown in FIG. 1, and a first form B consisting of a waist tightening portion 2 connected to the upper end portions of the first strong tightening portion 3 and the second strong tightening portion 4, which can be tightened around the waist, ring-shaped left and right thigh tightening portions 5 connected to the lower end portions of the first strong tightening portion 3 and the second strong tightening portion 4, which have a tightening force capable of tightening around the thighs 18, and a base fabric 6 having elasticity sewn or bonded to the first strong tightening portion 3 and the second strong tightening portion 4, which is worn in a state of almost intimate contact with the surface of the wearer 80 corresponding to at least the range from the waist tightening portion 2 to the thigh tightening portion 5.

[0024] An example of the garment 1 using the first type of tightening portion 8 is a spats-type garment 1A, which is made up of the belt-shaped waist tightening portion 2, the belt-shaped first strong tightening portion 3, the belt-shaped second strong tightening portion 4, and a base fabric 6 that can cover the surface of the wearer 80 in a nearly tight-fitting state. The spats-type garment 1A may have a base fabric 6 that covers at least the area from the waist of the wearer 80 to above the knees, and includes spats or supporters that cover the area from the waist of the wearer 80 to above the knees. Furthermore, the spats-type garment 1A includes spats whose upper end position is the waist of the wearer 80 and whose lower end position covers the ankles of the wearer 80, and spats whose upper end position is the waist of the wearer 80 and whose lower end position covers the area below the knees of the wearer 80.

[0025] The spats-type garment 1A includes spats-type garment 1Aa, which uses the first strong tightening portion 3, the second strong tightening portion 4, and the tightening portion 8 of the first form A, as shown in Figures 1, 3 and 4, and spats-type garment 1Ab, which uses the first strong tightening portion 3, the second strong tightening portion 4, and the tightening portion 8 of the first form B, as shown in Figure 13.

[0026] Next, as an example of a garment 1 using the tightening portion 8 of the second form, as shown in Fig. 2, Fig. 5, and Fig. 6, there is a garment 1 consisting of the first strong tightening portion 3 in a belt shape, the second strong tightening portion 4 in a belt shape, the belt-shaped waist tightening portion 2 forming a ring shape, and the left and right thigh tightening portions 5 in a belt shape forming a ring shape, such as a belt-shaped garment 1B. Below, the belt-shaped garment 1B will be described as a representative of garments 1 using the tightening portion 8 of the second form. As shown in Fig. 2, Fig. 5, and Fig. 6, the belt-shaped garment 1B using the tightening portion 8 of the second form consists of the waist tightening portion 2, the thigh tightening portion 5, the first strong tightening portion 3, and the second strong tightening portion 4, and the upper ends of the first strong tightening portion 3 and the second strong tightening portion 4 are connected to the waist tightening portion 2, and the lower ends of the first strong tightening portion 3 and the second strong tightening portion 4 are connected to the thigh tightening portions 5.

[0027] The spats-type garment 1A has a first strong tightening portion 3 and a second strong tightening portion 4 made of at least two belt-shaped strong tightening fabrics having a strong tightening force, a waist tightening portion 2 made of a tightening fabric having the same or less tightening force as the first strong tightening portion 3 or the second strong tightening portion 4, and a base fabric 6 having a weak tightening force and elasticity. The spats-type garment 1A may further have belt-shaped left and right thigh tightening portions 5 made of a tightening fabric having the same or less tightening force as the first strong tightening portion 3 or the second strong tightening portion 4. The belt-type garment 1B has a first strong tightening portion 3 and a second strong tightening portion 4 made of at least two belt-shaped strong tightening fabrics having a strong tightening force, and a waist tightening portion 2 and a belt-shaped left and right thigh tightening portions 5 made of a tightening fabric having the same or less tightening force as the first strong tightening portion 3 or the second strong tightening portion 4.

[0028] The width of the belt-shaped waist tightening portion 2, the belt-shaped left and right thigh tightening portions 5, the first strong tightening portion 3, and the second strong tightening portion 4 is not limited, and may be, for example, any width between 3 cm and 10 cm, as long as it has a predetermined width that provides sufficient tightening force to regulate or suppress the movement of a specific bone portion that rotates inward or outward.

[0029] The tightening force of the first strong tightening portion 3 or the second strong tightening portion 4 has a strong tightening force that affects the internal and external rotation movement of the femur 12 when the first strong tightening portion 3 or the second strong tightening portion 4 becomes tensed, the tightening force of the waist tightening portion 2 or the thigh tightening portion 5 is a tightening force that does not shift the attachment position of the first strong tightening portion 3 or the second strong tightening portion 4 relative to the body of the wearer 80 and has a tightening force that is the same as or less than the tightening force of the first strong tightening portion 3 or the second strong tightening portion 4, and the base fabric 6 has elasticity that allows it to fit closely to the body of the wearer 80 and has a tightening force lower than the tightening force of the waist tightening portion 2 or the thigh tightening portion 5.

[0030] The tightening force means the resistance of the material to stretching. Therefore, a large effect is obtained when there is a large difference between the tightening force of the base fabric 6 and the tightening force of the first strong tightening portion 3 or the second strong tightening portion 4 of the strong tightening fabric having a stronger tightening force. When the difference in the tightening forces is small, the effect is reduced.

[0031] The tightening force was measured based on the load required for a certain stretch on the fabric, in accordance with JIS L 1096 A method. A bench-top precision universal testing machine (AUTOGRAPH AGS-X 5kN, manufactured by Shimadzu Corporation) was used, the tensile speed was set to 200 mm / min, and the size of the sample fabric was 25 mm wide, 150 mm long, and the gripping distance was 100 mm.

[0032] A mannequin was fitted with the spats-type garment 1Ab, and the elongation rate when worn, which is the difference between the flat measurement and the measurement when worn, for the waist tightening portion 2, the first strong tightening portion 3, the second strong tightening portion 4, and the thigh tightening portion 5, was approximately 30%, so it was decided to measure the resistance of the material to elongation by measuring the load required when the sample fabric was elongated by 30%.

[0033] From the measurement results, the load of the base fabric 6 at 30% elongation is preferably 1.0 to 1.5 N vertically and 0.5 to 1.0 N horizontally. Within these ranges, the wearing comfort is excellent. Furthermore, the load of the first strong tightening portion 3 and the second tightening portion 4 at 30% elongation is preferably 6.0 to 8.0 N in the longitudinal direction for competitive sports, and is preferably 1.5 to 2.0 N in the longitudinal direction for everyday life. The load of the waist tightening portion 2 and the thigh tightening portion 5 at 30% elongation is preferably 1.25 to 1.75 N in the longitudinal direction.

[0034] The band-shaped strong tightening fabric of the first strong tightening portion 3 and the second strong tightening portion 4 has a tightening force such that, when the strong tightening fabric is tensed, the tightening force in the longitudinal direction affects the internal and external rotation movement of the femur 12. The tightening forces in the lateral direction of the first strong tightening portion 3 and the second strong tightening portion 4 are all the same as or less than the respective tightening forces in the longitudinal direction, and may be any strength of tightening force as long as the tightening forces do not displace the attachment position of the first strong tightening portion 3 or the second strong tightening portion 4 relative to the body of the wearer 80.

[0035] The low tightening force fabric of the base fabric 6 of the garment 1 of the present invention, the medium tightening force fabric or the high tightening force fabric of the thigh tightening portion 5 or the waist tightening portion 2, and the high tightening force fabric having a high tightening force of the first strong tightening portion 3 or the second strong tightening portion 4 are each a stretch material having elasticity and different tightening forces, and it is preferable that the stretch material is at least one fabric selected from two-way stretch knitted fabrics and two-way stretch woven fabrics that stretch in the vertical and horizontal directions.

[0036] The two-way stretch knitted or woven fabric may be mainly composed of polyester fiber yarn and elastic yarn, or mainly composed of nylon fiber yarn and elastic yarn. Alternatively, the main component yarn may be cotton and elastic yarn. Here, the main component yarn means that the total of both components is 80% by weight or more. When polyester fiber yarn is used, it dries easily even when sweating. When nylon fiber yarn is used, the knitted fabric has a soft touch.

[0037] The knitted or woven fabric may have any structure. The woven fabric may have three basic structures, namely, plain weave, twill weave, and satin weave, which are generally well known, or a variation weave. The knitted fabric may be a fabric knitted by a raschel warp knitting machine, a fabric knitted by a tricot warp knitting machine, or a fabric knitted by a knit weft knitting machine, which are generally well known. For example, a half structure knitted by a tricot warp knitting machine or a power net structure knitted by a raschel warp knitting machine may be mentioned. The knitted weft knitted fabric may have any structure, such as plain knit (plain knit), rib knit, pearl knit, or smooth knit (double-sided knit). The knitted fabric knitted by a knit weft knitting machine may be a fabric knitted by a circular knitting machine or a flat knitting machine. In the case of weft knitting, it is also possible to knit a weak tightening force material and a strong tightening force material together without sewing. For example, there is a machine called "FIRST-X" by Shima Seiki Seisakusho that can be used to knit the waist and both legs at the same time to produce seamless knit products. Also, by utilizing the difference in chemical resistance, it is possible to create a fabric that realizes strong and weak tightening force with a single material by using opal processing, which removes only one of the fibers of a mixed woven or knitted fabric to create a watermark pattern.

[0038] Furthermore, it is also possible to use a fully computer-controlled device called a "seamless body inner knitting machine" made by SANTONI of Italy to knit a combination of high and low tension materials seamlessly into a cylindrical shape for the lower abdomen and legs.

[0039] The woven or knitted fabric preferably contains elastic yarn having stretchability, such as polyurethane yarn, at least in part.

[0040] The elastic yarn is preferably at least one selected from polyurethane-based elastic yarn and polyester-based elastic yarn, because they have high stretchability and are suitable for sportswear. The elastic yarn may be either bare yarn or covered yarn, the surface of which is covered with polyester fiber or nylon fiber.

[0041] Fabrics may be made using highly crimped false-twisted yarns such as polyester or nylon that have been subjected to highly crimped false-twisting to give them elasticity, at least in part or in whole. It is also possible to simply use a plurality of such elastic knits stacked together. Furthermore, two-layer laminate fabrics in which one side of a knit fabric is laminated, and three-layer laminate fabrics in which an elastic polyurethane sheet is sandwiched between the elastic knit fabrics and laminated to form three layers may also be used.

[0042] Next, as a method of giving the fabric material "strong" and "weak" tightening force, and making the elastic material (weak tightening force material) used in the base fabric 6, the tightening material (medium tightening force material) used in the waist tightening portion 2 or the thigh tightening portion 5, and the strong tightening force material used in the waist tightening portion 2, the thigh tightening portion 5, the first strong tightening portion 3, or the second strong tightening portion 4, the fabric material can be given "strong" and "weak" tightening force by changing the blend ratio of polyurethane yarn and high shrink false twist textured yarn (hereinafter referred to as elastic yarn). As a method of changing the blend ratio, there is a method of changing the thickness of the elastic yarn from "thick" to "thin" to give a "large" and "small" blend ratio, and a method of changing the ratio of the elastic yarn to "somewhat" while keeping the thickness of the elastic yarn the same. It is also possible to change the knitting density to "dense and sparse" when the blend ratio of the elastic yarn is constant. Furthermore, it is possible to give the fabric "strong or weak" tightening power by using fabrics with different types of elastic threads, by using laminated and non-laminated fabrics, or by changing the number of layers of the same fabric.

[0043] The "strong" tightening force of the weak tightening force material of the base fabric 6 which has elasticity and weak tightening force, the medium tightening force material which may be used in the thigh tightening portion 5 or the waist tightening portion 2, and the strong tightening force material which may be used in the waist tightening portion 2 or the thigh tightening portion 5 and which is used in the first strong tightening portion 3 or the second strong tightening portion 4 can be confirmed by the magnitude of the load on the fabric required for a certain elongation. In other words, a fabric with a strong tightening force requires a large load on the fabric for a certain elongation, and a weak fabric requires a small load on the fabric for a certain elongation.

[0044] The low-tightening force material, medium-tightening force material and high-tightening force material can be integrated by sewing or bonding to form spats-type clothing, and the medium-tightening force material and high-tightening force material can be integrated by sewing or bonding to form belt-type clothing.

[0045] The sewing method includes a method using a sewing machine that forms seams such as a lock stitch, a chain stitch, a single-needle overlock, a double-needle overlock, a flat seam, etc., but the type of seam is not limited to these. However, it is preferable to use a single-needle overlock, a double-stitch overlock, or a flat seam, which have stretchability and are less likely to cause discomfort when worn.

[0046] One bonding method is to provide a seam between the two types of fabric (components) to be joined, and then sandwich a heat-melting seam tape made of polyurethane or silicone or other resin, which melts when heated and penetrates the fabric and solidifies after cooling, between the fabric at the seam, and then heat press to bond the fabrics.However, it is desirable to give the seam stretchability, just like with sewing, to eliminate any discomfort when worn.

[0047] In addition, the first strong fastening portion 3 and the second strong fastening portion 4 are strips made of a strong fastening material. The difference in the tightening force between the base fabric 6 made of a weak tightening material and the base fabric 6 made of a weak tightening material is, for example, 3 times that of the base fabric 6. When the load at 0% elongation is 1.0 to 1.5 N vertically and 0.5 to 1.0 N horizontally, it has a strong tightening force. The load when the first strong tightening portion 3 or the second strong tightening portion 4 is elongated by 30% is 1.5 to 2.0 N in the longitudinal direction. In this case, discomfort is unlikely to occur when worn.

[0048] In the present invention, to achieve a "nearly fitted" state, the garment is formed so that the circumference is 50% to 110%, more preferably 70% to 95%, and the length is 75% to 100%, more preferably 85% to 100%, of the naked human body size. Of course, the size of the human body varies from person to person, so the above ratios are merely a guideline.

[0049] The fabric is not particularly limited, and examples of the fabric that can be used include polyester fibers such as polyethylene terephthalate, polytrimethylene terephthalate, and polybutylene terephthalate, polyurethane fibers, polyamide fibers, acetate fibers, cotton fibers, rayon fibers, ethylene vinyl alcohol fibers, and nylon fibers.

[0050] The waist tightening parts 2 will now be described. As shown in Fig. 1(a) or Fig. 13(a) showing a leggings-type garment 1A, or Fig. 5(a) showing a belt-type garment 1B, the waist tightening parts 2 are arranged in the front and back body at positions corresponding to the waist, and can be worn continuously around the waist so that the garments 1A and 1B do not slip down even when the wearer 80 exercises. As shown in Fig. 12, the waist tightening parts 2 can be in the form of a ring-shaped belt having a medium or strong tightening force that surrounds the waist, or in the form of a string (not shown) that is wrapped around the waist and tied.

[0051] The waist tightening portion 2 can prevent the upper ends of the first strong tightening portion 3 and the second strong tightening portion 4 from shifting downward in the vertical and horizontal directions of the wearer's 80 body, even when the wearer 80 is exercising, such as walking or running.

[0052] Next, the thigh tightening portion 5 will be described. The left and right ring-shaped thigh tightening portions 5 are arranged at positions that correspond to approximately the center of the left and right thighs in the longitudinal direction, as shown in Figs. 5 and 6 which show a belt-type garment 1B, and the garment can be worn continuously on the thighs 18 so that it does not slip down even when the wearer 80 exercises. The thigh tightening portions 5 have a belt-like form with a ring-shaped medium or strong tightening force that surrounds the thighs 18, as shown in Fig. 12. The thigh tightening portions 5 can also be added to a spats-type garment 1A, and a spats-type garment 1Ab in this case is shown in Fig. 13.

[0053] In the case of the belt-type garment 1B, the thigh tightening portions 5 can prevent the lower ends of the first strong tightening portions 3 and the second strong tightening portions 4 from moving in the up-down and left-right directions of the body of the wearer 80, even when the wearer 80 is exercising, such as walking or running. Spats-type garments 1Ab that have the thigh tightening portions 5 can also be prevented from moving in the same way.

[0054] The base fabric 6 having the weak tightening force, i.e., elasticity, is a constituent element of the spats-type garment 1A, and is the base fabric of the garment 1A which is worn in a state where it is in almost intimate contact with the surface of the wearer 80. Therefore, because the garment 1A is in almost intimate contact with the surface of the wearer 80, it is possible to prevent the lower end of the first strong tightening portion 3 and the lower end of the second strong tightening portion 4, which are sewn or bonded to the garment 1A, from shifting position in the vertical and horizontal directions of the wearer's 80's body, even when the wearer 80 is exercising, such as walking or running.

[0055] Next, as shown in Fig. 1 and Fig. 13 which show a leggings-type garment 1A, or as shown in Fig. 2 which shows a belt-type garment 1B, the strong tightening fabric forms the first strong tightening portion 3 and the second strong tightening portion 4. The strong tightening fabric can also be used for the waist tightening portion 2 or the thigh tightening portion 5.

[0056] Next, the first strong tightening portion 3 will be described. As shown in Figs. 3 and 4 showing a state in which the leggings-type garment 1A is worn, and as shown in Figs. 5 and 6 showing a state in which the belt-type garment 1B is worn, the first strong tightening portion 3 is connected at its upper end to the waist tightening portion 2 of the back body, passes through a portion corresponding to the lower vicinity of the greater trochanter 11 on the lateral side, passes through the front of the thigh 18, and is arranged in a spiral shape with the lower end being approximately the center in the longitudinal direction of the inner side of the thigh 18. In the case of leggings-type garment 1Aa, the lower end is sewn or bonded to the base fabric 6 as shown in Fig. 1, in the case of leggings-type garment 1Ab, the lower end is connected to the thigh tightening portion 5 as shown in Fig. 13, and in the case of belt-type garment 1B, the lower end is connected to the thigh tightening portion 5 as shown in Fig. 2. As a result, the positions of the upper end and the lower end do not shift from the positions corresponding to the parts of the body of the wearer 80 even when the wearer 80 exercises.

[0057] 4(a) and 6(a), the first strong tightening portion 3 intersects with the second strong tightening portion 4 at a portion corresponding to the front-lower side of the greater trochanter 11 (the greater trochanter corresponding portion 11a corresponds to this portion). As a result, by connecting with the second strong tightening portion 4 at a portion corresponding to the front-lower side of the greater trochanter 11, the first strong tightening portion 3 is less susceptible to the influence of the movement of the wearer 80, and it is possible to prevent the first strong tightening portion 3 from shifting from the portion corresponding to the immediate lower side of the greater trochanter 11.

[0058] Furthermore, the lower ends of the first strong tightening portion 3 and the second strong tightening portion 4 are connected at approximately the center in the longitudinal direction of the inner thigh, as shown in Figure 4(c) or Figure 6(b), or are close to each other with a gap G formed between them, at approximately the center in the longitudinal direction of the inner thigh, as shown in Figure 4(b).

[0059] The first strong tightening portion 3 has a function of bringing about a second effect. As shown in Fig. 10(b), when the wearer 80, for example, assumes a crouching posture from a vertical jump toward landing, flexing the hip joint 10 causes the second strong tightening portion 4 to relax and the first strong tightening portion 3 to tense. Then, the second strong tightening portion 3, which has a strong tightening force pulled in the longitudinal direction of the thigh 18, exerts a strong pressing force on the portion corresponding to the femur 12 at the anterior lower part of the greater trochanter 11, and this pressing force prevents the femur 12 from rotating inward relative to the acetabulum 21. The same effect is also produced when the hip joint 10 is flexed while walking or running.

[0060] When the hip joint 10 is flexed, the tensed first strong tightening portion 3 rotates the femur 12 in a direction that prevents the femur 12 from rotating inward, thereby preventing the knee from turning inward when squatting.

[0061] The first strong tightening portion 3 applies an external force by tightening to a portion of the femur 12 immediately below the greater trochanter 11, not immediately above or beside the greater trochanter 11, which makes it possible to apply a torque that affects the rotation of the spherical femoral head 13.

[0062] Next, the second strong tightening portion 4 will be described. As shown in Figs. 3 and 4 showing a state in which the leggings-type garment 1A is worn, or as shown in Figs. 5 and 6 showing a state in which the belt-type garment 1B is worn, the second strong tightening portion 4 is connected at its upper end to the waist tightening portion 2 of the front body, passes through the front of the hip joint 10, passes through a portion corresponding to the lower part of the greater trochanter 11 on the lateral side, passes through the rear surface of the thigh 18, and is connected at its lower end to the thigh tightening portion 5 at approximately the center in the longitudinal direction of the inner side of the thigh 18, and is arranged in a spiral shape. In the case of leggings-type garment 1Aa, the lower end is sewn or bonded to the base fabric 6 as shown in Fig. 1, in the case of leggings-type garment 1Ab, the lower end is connected to the thigh tightening portion 5 as shown in Fig. 13, and in the case of belt-type garment 1B, the lower end is connected to the thigh tightening portion 5 as shown in Fig. 2. As a result, the positions of the upper end and the lower end do not shift from the positions corresponding to the parts of the body of the wearer 80 even when the wearer 80 exercises.

[0063] 4(a) and 6(a), the second strong tightening portion 4 intersects with the first strong tightening portion 3 at a portion corresponding to the front-lower side of the greater trochanter 11 (the greater trochanter corresponding portion 11a corresponds to this portion). As a result, by connecting with the first strong tightening portion 3 at a portion corresponding to the front-lower side of the greater trochanter 11, the second strong tightening portion 4 is less susceptible to the influence of the movement of the wearer 80, and it is possible to prevent the second strong tightening portion 4 from shifting from the portion corresponding to the front-lower side of the greater trochanter 11.

[0064] The second strong tightening portion 4 has a function of bringing about a first effect. As shown in Fig. 10(a), when the wearer 80 extends the hip joint 10 on the push-off side (other side 52) while walking or running, for example, the first strong tightening portion 3 relaxes and the second strong tightening portion 4 tightens. Then, as shown in Fig. 9, the second strong tightening portion 4, which has a strong tightening force pulled in the longitudinal direction of the femur 18, applies a strong pressing force to the portion corresponding to the femur 12 immediately below the greater trochanter 11, and this pressing force causes the femur 12 to rotate inward relative to the acetabulum 21.

[0065] By encouraging the femur 12 to rotate inward, the stride length can be increased to L2 (a2+b2) as shown in Fig. 11(b) compared to the stride length L1 (a1+b1) when the femur 12 is not encouraged to rotate inward, as shown in Fig. 11(a). In the present invention, the stride length L1 means the distance between the toe of the foot on one side 51 and the heel of the foot on the other side 52.

[0066] From the above, the garment 1 of the present invention has a first effect that when the hip joint 10 is extended when pushing off while running or walking, the first strong tightening portion 3 becomes tense, which induces internal rotation of the hip joint when pushing off, making the stride wider and the walking speed faster. Also, a second effect is that when the hip joint 10 is flexed, the second strong tightening portion 4 becomes tense, preventing internal rotation of the hip joint, and when crouching down to land after a vertical jump, the direction of the knees and the direction of the toes are aligned so that the knees do not turn inward, allowing the wearer to land straight, thereby preventing knee injuries.
