Description

  The present invention relates to apparel for lower limbs used mainly for sports.

Conventionally, clothing for lower limbs has been used for sports and the like to protect the body and keep warm. These lower limb apparel can be used to improve blood circulation by pressing the lower limbs in close contact with the lower limbs, speeding up the recovery of fatigue, improving the exercise capacity by pressing muscles and tendons, etc. Those that are fixed and have a sprain prevention function are known.
In order to improve the blood circulation of the lower limbs described above, the pressure to be compressed gradually decreases as it goes from the tip of the foot toward the upper part, and this is performed by sequentially changing the stitch length on the shin side. ing. (Patent Document 1)

  In addition, in order to prevent ankle varus or valgus sprain that tends to occur during exercise etc., it is fixed by winding taping tape around the ankle part, which is effective. Such taping has to be wound and removed every time, which is very laborious. A special taping technique is also required.

Therefore, it is conceivable to attach a low-stretch and highly compressible cylindrical piece to the lower limb clothing so that the same effect as taping can be obtained on the lower limb clothing, but the degree of compression is gradually increased. It is difficult to change and there is a big difference between the circumference of the ankle part of the lower limb and the circumference of the buttocks, so it is difficult for the user to attach and detach through the heel part during use, and it is difficult to use It was.

  The present invention can protect the body and keep warm in the clothing for the lower limbs, improves the blood circulation by pressing closely against the lower limbs and accelerates the recovery of fatigue, and compresses muscles and tendons. In addition to improving athletic ability, it has the same effect as taping at the ankle to prevent ankle varus or valgus sprain during exercise, etc. An object is to obtain a small amount that can be easily attached and detached.

  The present invention is a garment for a lower limb to be worn on a lower limb, and includes a garment body that has elasticity and can apply pressure to the entire foot, and the ankle portion of the garment body is more strongly compressed than the body. It is equipped with a clamping part that covers the instep, arch, ankle joint, and ankle so that it can be added. The upper end of the tightening pressure part is formed so as to be inclined toward the upper part of the lower leg. In particular, the main body is designed so that the compression action gradually becomes smaller in accordance with the flow of veins from the distal end side of the foot.

Further, the tightening pressure portion further includes a lower-stretching tightening main portion extending from the inner ankle of the lower leg to the outer ankle through the foot arch. Effectively prevent joint varus or valgus sprain.
The garment body is provided with a knee clamping portion that covers the lower part of the knee in an annular shape and surrounds the periphery of the patella to stabilize the patella, and to make the movement of the lower limbs more effective.

According to the present invention, when performing sports or the like, the body can be protected or kept warm, and the entire leg is pressed against the lower limb. In addition, the blood pressure can be improved by squeezing so that it gradually weakens as it goes from the toes to the upper part, so that recovery from fatigue can be accelerated, and muscles and tendons are squeezed to improve exercise capacity be able to.
In addition, the ankle part can be fixed and the ankle joint is protected by a clamping part that covers the instep, arch, ankle joint, and ankle, and its upper end is inclined toward the upper leg. can do. And since the upper end part of the above-mentioned tightening pressure part is inclined toward the lower leg upper part, the compression action is gradually reduced upward, and smooth compression along the flow of the vein becomes possible. The feeling of strangeness can be reduced. Further, when worn during use, the tightening pressure portion can be gradually expanded so that the heel of the foot can pass smoothly and can be easily attached and detached.

The clothing main body 2 that covers most of the clothing 1 for the lower limbs is stretchable, thin and lightweight so that it does not feel uncomfortable when worn, and has a feeling of fit to the lower limbs and is breathable. Thus, it is formed of a woven fabric or a knitted fabric made of a material that is relatively thin so as not to impede motility, has little water retention, and is highly breathable.
As such a material, for example, a tengu, a mill, a smooth, a russell, a tricot made of polyamide fiber, polyester fiber and polyurethane fiber can be used.

  The stretchability of the garment body 2 is more preferably stretchable in both the vertical and horizontal directions. For example, it is preferable to use a two-way tricot of a tricot knitted fabric, the type of yarn, the content of elastic fibers, etc. The compression action can be adjusted by selecting.

  The lower limb apparel can be formed into a tights type covering from the sole to the waist, an over knee type covering from the sole to the top of the knee, and a high socks type covering from the sole to the bottom of the knee.

A tightening pressure portion 3 is formed below the clothing main body 2. The clamp part 3 is formed with an arch part 4, an instep part 5, an ankle joint part 6 and an ankle part 7 so as to cover the arch, the instep, the ankle joint and the ankle of the foot. Not covered. The upper end portion 9 of the tightening pressure portion 3 is formed to be inclined with respect to the sagittal plane.
In the illustrated example, it is formed in an inclined shape so as to rise from the lower leg rear surface 12 toward the middle part of the lower leg front 13, but it rises toward a position higher or lower than the middle part 14 of the lower leg front 13. It can also be formed in an inclined shape that descends.

The upper end portion 9 of the tightening pressure portion 3 may be formed in an inclined shape toward the upper part of the lower leg, so that the upper end part 9 may be inclined upward from the lower leg front surface 13 toward the lower leg rear surface 12 It can be formed in an appropriate shape such as an inclined shape that rises toward the side surface.
By forming the upper end portion 9 of the tightening pressure portion 3 in an inclined shape, the compression action on the lower leg continuously decreases upward, and when worn, the foot moves the lower limb clothing downward from above. The heel part 8 that is difficult to pass through can be smoothly worn by passing through with little resistance.

A part of the tightening pressure part 3 further extends and contracts further from the ankle part 18 around the ankle 17 on the inner side of the lower leg through the sole 19 to the ankle part 21 around the outer ankle 20. Thus, a stronger compression action and ankle joint fixing action can be obtained so as to be pulled upward from the sole.
By this tightening pressure main portion 22, the ankle is more reliably fixed, and the ankle joint can be effectively prevented from being varus or valgus sprained.
In the illustrated example, the tightening pressure main portion 22 reaches the upper end portion 9 of the tightening pressure portion 3 while sandwiching the ankle from both sides by the inner ankle portion 18 and the outer ankle portion 21 from the sole portion 19. Forming.

  The pressure action on the ankle portion having the tightening pressure portion 3 in the lower limb apparel 1 may be about 18 to 40 hPa, and about 10 to 28 hPa in the upper lower leg maximum circumference 25, and compression on the ankle portion. The compression action is made weaker as it goes upward so that it becomes about 70% of the action.

  In the case of an over knee type or a tights type, the knee part 26 is also covered, so it is good that the pressure action on the ankle part is about 5 to 70% at about 7 to 20 hPa. In the case of a tights type, the compression action of the upper thigh part 27 should be about 16 hPa or less, and should be about 30% of the compression action on the ankle part. Try to weaken it.

  In the illustrated example, the compression action is obtained, and a tightening pressure portion 28 is also provided on the knee portion 26. The clamping portion 28 includes an annular portion 31 located on the lower knee of the patella 29 and a patella portion 32 surrounding the patella 29 from the rear to the front of the annular portion 31. The patella ligament when the knee is positioned is fixed in a compressed state.

  That is, if exercise is performed and the knee is used violently, the quadriceps muscles become less flexible with fatigue and the patella 29 tends to move upward. Since the patella 29 is restrained from being moved and kept in a fixed position by the compression action of the patella ligament 32, the knee can be used without any trouble.

  Further, the patella portion 32 of the tightening pressure portion 28 of the knee surrounds the periphery of the patella 29 from the rear side to the front side of the annular portion 31 located at the lower portion of the knee so as to press the knee. When bending, no trouble occurs, and the compression action naturally increases greatly during bending, so that an effective action can be exerted.

  Further, as shown in the figure, by providing a discontinuous opening 33 in a part of the patella 32, it is possible to obtain a compression action on the patella ligament without excessively restricting the knee flexion. It is preferable that the opening 33 is provided on the side of the patella 32 so as to be positioned in the inner part of the knee. Then, as will be described below, when the fastening body 28 is formed by laminating a low stretchable material on the garment body 2 and sewing it, its manufacture is also easy.

Those tights type shown in figures is provided with the tightening pressure portion 37 to portion 36 of the waist, which will alleviate the external action exerted on the portion of the waist by applying compression acts on the portion 36 of the waist The waist can be kept stable and protected, and the tights can be prevented from being removed during use.

  As described above, in the ankle portion, the clamping pressure portion 3 and the clamping pressure main portion 22 cooperate to obtain a compression action of about 18 to 40 hPa. In the case of obtaining such compression and fixing action, a material capable of obtaining such a compression action can be selected and connected to the garment body 2 so as to be integrated.

  Further, a material to be the clamping pressure portion 3 is laminated on the ankle portion of the clothing main body 2 and the periphery thereof is sewn, and the material is further piled on the clamping pressure portion 3 in the clamping pressure main portion 22. Thus, the above-described pressing and fixing actions can be obtained by laminating and sewing the periphery thereof, or by integrating the overlapping state by another appropriate method.

  For example, when obtaining a garment for tight legs, for example, the garment body 2 that covers most of the lower limbs is approximately 0.8 to 3.0 N / 2.54 cm when stretched 30% in the circumferential direction of the garment. It is preferable to use a material that can obtain an elongation force of about 0.8 to 3.0 N / 2.54 cm at 30% elongation in the direction.

  The tightening portion 3 has an extension force of about 1.8 to 8.0 N / 2.54 cm when stretched 30% in the circumferential direction and about 3.8 N / 2.54 cm or more when stretched 30% in the vertical direction. What is obtained may be used, and the tightening pressure main portion 22 is about 2.8 to 13.0 N / 2.54 cm when stretched 30% in the circumferential direction and about 6.8 N / 2 when stretched 30% in the vertical direction. It is preferable to use a material that can provide an extension force of .54 cm or more.

In the figure, the garment body 2 formed in a tights shape so as to cover the entire lower limb is approximately 0.8 to 3.0 N / 2.54 cm when stretched 30% in the circumferential direction of the garment and 30 in the vertical direction. A material that can obtain an elongation of about 0.8 to 3.0 N / 2.54 cm at the time of% elongation is used.
The tightening pressure portion 3 has an elongation of about 1.0 to 5.0 N / 2.54 cm when stretched 30% in the circumferential direction of the garment and about 3.0 N / 2.54 cm or more when stretched 30% in the vertical direction. One that can obtain force is laminated on the above-described clothing body 2 and laminated, and the peripheral edge portion 10 is sewn and integrated, and the clamping main portion 22 has two pieces. Overlapping and integrated. In this way, the compression action described above can be obtained. When these are stacked, they may be stacked on the outer side of the clothing main body, may be stacked on the inner side, or may be stacked separately on both the inner and outer sides.

Examples of the garment body 2 that can be used include two-way tricot, cardboard knit, and other knitted fabrics. Specifically, two-way tricot composed of nylon fiber and polyurethane fiber, and two-way composed of polyester fiber and polyurethane fiber. A tricot or the like can be used.
In addition, what is piled up in the clamping pressure part 3 and the clamping pressure main part 22 includes, for example, a two-way tricot, a russell satin net, a power net, and other knitted fabrics. Specifically, nylon fiber and polyurethane Nylon satin net or power net made of fiber can be used.

  Further, in the illustrated example, the tightening pressure portion 28 formed on the knee portion 26 is also integrally formed by laminating and laminating one piece of a strong stretching force on the clothing body 2 in the same manner as described above. Similarly, the tightening pressure portion 37 in the waist portion 36 is also integrally formed on the garment body 2 by superimposing one having a strong extension force on the clothing body 2. Also in the knee portion 26 and the waist portion 36, a desired compression action can be obtained by changing the material without depending on the overlapping as described above.

  Further, in the illustrated one, a tightening pressure portion 41 similar to the above is formed on the rear lower surface 12 so as to extend from the ankle portion 7 to the annular portion 31 of the knee tightening pressure portion 28. Supports muscles and protects them from damage.

When using the garment 1 for the lower limbs of the tights type, if the foot is inserted from the waist portion 36 and the garment body 2 is stretched and worn, the heel portion 8 protrudes after passing through the patella portion 32. Although the subject to be there by the resistance that are smooth even from the upper end portion 9 of the clamping pressure portion 3 that covers the portion of the ankle is in the inclined state toward the top, the resistance is gradually stronger Can be worn.

When the ankle enters the tightening pressure portion 3, the ankle and the ankle joint portion are appropriately tightened and fixed by the tightening pressure portion 3 and the tightening pressure main portion 22. -The range of motion can be limited against valgus and the ankle can be protected.
The lower limb portion is compressed by the lower limb apparel 1, but since this compression action gradually decreases from the ankle portion toward the waist portion, it promotes venous return, improves exercise ability, fatigue It can contribute to recovery and other effects effectively.

  This lower limb apparel can be widely applied to tights type from ankle to waist as described above, over knee type from ankle to above knee, high socks type from ankle to under knee, It can be widely used as both underwear and outerwear.
