Description

The present invention relates to athletic wear such as socks, stockings and tights, and a method of using the same.

  Conventionally, a supporter, an auxiliary tool or a stocking to be worn on an ankle or the like has been developed.

JP2009-287151A (front page) JP2007-332470A (front page) WO2010-139939A (front page) JP11-196902A (front page)

JP2009-287151A discloses a sock having a band portion for tightening an ankle or an instep in a circumferential direction. In the sock, the portion covering the heel is not bent when not worn.

  JP2007-332470A discloses a supporter that can support a foot when worn and has high fit.

WO2010-139939A discloses a sock for correction provided with an elastic panel for supporting dorsiflexion of a foot.

  JP11-196902A discloses the following contents.

  When a person runs, the leg muscles are transmitted to the foot by rotating the ankle joint (joint of the heel) in the direction to bring the toe closer to the ground, that is, by bending the ankle joint to the bottom. Kick the ground. Therefore, in order to run fast and jump high, it is necessary to increase the plantar flexion force that causes the ankle joint to flex. The plantar flexion force varies depending on the angle of the ankle joint. During running, the plantar flexion force is maximized when the angle of the ankle joint is about 130 to 160 degrees. Therefore, it is necessary to control the angle of the ankle joint in order to maintain an optimal range of motion where the plantar flexion force is large during exercise.

  When the angle of the ankle joint is not controlled at all, when the vertical load becomes the maximum after the foot is touched, the load causes a drop of the heel (dorsiflexion). Therefore, the angle of the ankle joint is smaller than the optimum movable range. If the optimum range of motion is deviated in this manner, the bottom flexion force is reduced, the force for kicking the ground is reduced, and the grounding time is increased and the operation is slowed as the saddle falls. Therefore, motor function is reduced.

  The motor function assisting structure disclosed in this prior document is disposed from the heel of the foot to the ankle in a position that covers the lower part of the Achilles tendon from behind, and extends under the load after the front foot during grounding. It has a highly elastic drop restraining member that suppresses the fall of the heel of the foot.

The Young's modulus of the material constituting the drop-suppressing member of the above-mentioned prior art document is preferably about 5 to 300 kg / cm ² (49 to 2940 N / cm ² ), although it varies depending on the leg strength and purpose of the wearer. Further, the maximum breaking elongation of the drop restraining member is preferably 10% or more. The spring constant (tensile load / elongation) of the drop restraining member is preferably about 15 to 900 kg / cm (147 to 8820 N / cm).

  As disclosed in the prior document, the tensile force of the highly elastic drop restraining member can restrain the drop of the heel, and the angle of the ankle joint will be kept within the optimum movable range. Therefore, a decrease in bottom flexion force will be suppressed, and an increase in ground contact time will be suppressed. In addition, the elastic energy accumulated in the drop restraining member that is extended along with the dorsiflexion operation will be released when kicking out the foot, and the bottom flexion force will increase.

  However, in the prior art document, a certain drop-in suppressing member has a complicated structure for fixing to a shoe with a resin belt. In other words, it is not wear that can be worn easily. Therefore, it is inevitable that the shoe has a special structure or the motor function assisting structure is complicated.

FIG. 16A and FIG. 16B show another prior example disclosed in the above-mentioned prior document.
This prior example has a sock-like structure worn on bare feet. In this sock, an integrated highly elastic member 105 is disposed from the toe to the back of the heel and ankle.

As shown in FIG. 16B, the highly elastic member 105 is pressed by the folded portion 103 and the belt portion 104 over the entire circumference of the ankle as shown in FIG. That is, it expands and contracts only at the part very close to the lower end of the lower leg. Therefore, the amount of elongation will be small.

In the invention of the above-mentioned prior art, the main purpose is to suppress the drop of wrinkles. Therefore, the spring constant of the highly elastic member is extremely large as 147 to 8820 N / cm. As will be described below, such a member having a large spring constant may cause a significant deterioration in the feeling of wearing shoes or socks, and may be a factor that does not sufficiently improve the motor function.

For example, the high-elasticity member 105 has a belt portion 104 and a folded portion 103 that extends over the entire circumference in a region above the ankle. Therefore, the part will be tightened at the folded portion 103. Therefore, the member 105 of the part will hardly extend.

In addition, the highly elastic member 105 expands in a tapered shape in the vicinity of the ankle joint as it goes upward, and as shown by an arrow 100, will exert a force that goes diagonally forward with respect to the heel. Therefore, the highly elastic member 105 will be in close contact with the back surface of the Achilles tendon in the region from the heel to the folded portion 103.
Therefore, in this case, a frictional force is generated on the surface of the foot when the highly elastic member 105 expands and contracts, and energy when the highly elastic member 105 contracts is lost, or the contracting speed of the highly elastic member 105 is small. In addition, it will lead to a decline in bottom flexion.

Furthermore, since the invention of the above-mentioned prior art mainly aims to keep the angle of the ankle joint during running within the optimum movable range (about 130 to 160 degrees), it is difficult for the foot to dorsiflex or the dorsiflexion of the foot. Will be significantly disturbed.

For example, the highly elastic member 105 covering the toes from the toes to the tips of the toes acts on the feet with a force compressing in the front-rear direction. It turned out to be bent greatly. It has also been found that the highly elastic member 105 applies a compressive force to the foot arch between the toe and the heel and deforms the foot arch so as to be convex upward. These significantly degrade exercise performance and wear.
Moreover, the tension of the highly elastic member 105 that exerts a contracting force between the toe and the heel will hardly exert a force toward the rear Db with respect to the entire sole. For this reason, moments in the plantar bending direction are unlikely to occur on the soles.

An object of the present invention is to provide an athletic wear that can be realized with a simple structure, increases the sole flexion force of the running foot without significantly lowering the wearing feeling, and thereby increases the exercise function, and a method for using the same. It is to be.

In the first invention of the wear for exercise, the wear includes a first portion 1 that continuously extends from the sole Fb through the rear surface Fr of the foot F along the rear surface Lr of the lower end Le of the lower leg L;
A second part 2 adapted to cover the front face Lf of the lower end Le of the lower leg L,
In the wearing state, the first part 1 and the second part 2 extend along the longitudinal direction Dy along the foot F and the lower leg L,
The elastic modulus Ey per unit width of the first part 1 in the longitudinal direction Dy at the time of 50% elongation is larger than that of the second part 2. That is, the elastic modulus per unit width of the second part 2 in the longitudinal direction Dy at the time of 50% elongation is smaller than the elastic modulus Ey of the first part 1. Here, the first invention is
The rear surface Lr of the lower leg L in an area at least 1/4 of the longitudinal direction Dy is upwardly covered from the lower end A2e of the outer fruit A2 of the lower leg L so that the first part 1 can extend and contract. It is characterized by being adapted.

The first part 1 having a large elastic modulus Ey in the longitudinal direction Dy generates a moment M in the plantar bending direction D1 around the heel (inner and outer fruits) of the foot. That is, when the first portion 1 is pulled from the sole Fb toward the lower end Le of the lower leg L, an external force toward the rear Db is applied to the sole Fb, while the longitudinal direction Dy is applied to the rear surface Fr of the foot. An external force directed upward is applied. These external forces act on the foot with a moment M in the buckling direction D1 around the heel An. Therefore, during the period from ground contact for short-distance running to takeoff, the first part applies a force to the foot to rotate the foot in the plantar bending direction.

As will be described in the results of the test described later, the rear surface of the first region L1 of ¼ from the lower end of the outer fruit of the lower leg expands and contracts particularly greatly during buckling to bottom bending. Therefore, a large bottom bending torque can be generated by covering the region with the first portion.

Preferably, the first part is adapted to cover at least one third of the rear surface of the second region upward from the lower end of the outer fruit of the lower leg in a state where the first part can be expanded and contracted.

As will be described in the results of the test described later, the rear surface of the second region of 1/3 of the lower leg extends upward and downward from the lower end of the outer fruit, and expands and contracts relatively greatly during the buckling to the bottom bending. Therefore, when the first portion covers the second region L2, a larger bottom bending torque can be generated.

In the present invention, “the first part extends continuously” includes a case where the first part is incompletely connected, and a member having a small elastic modulus may be partially provided.

“Lower leg” means a region from the lower end of the outer fruit to the lower part of the knee. Further, the “lower end of the lower leg” means the second region L2 that is 1/3 from the lower end of the outer fruit toward the upper side.
The “bottom bending direction D1” means a direction in which the toe rotates downward about the heel.

The exercise wear according to the first aspect of the first invention includes a first portion 1 that continuously extends from the sole Fb through the rear surface Fr of the foot F along the rear surface Lr of the lower end Le of the lower leg L,
A second part 2 adapted to cover the front face Lf of the lower end Le of the lower leg L,
In the wearing state, the first part 1 and the second part 2 extend along the longitudinal direction Dy along the foot F and the lower leg L,
The elastic modulus Ey per unit width of the first part 1 in the longitudinal direction Dy at 50% elongation is greater than that of the second part 2, where
The rear surface Lr of the lower leg L in an area at least 1/4 of the longitudinal direction Dy is upwardly covered from the lower end A2e of the outer fruit A2 of the lower leg L so that the first part 1 can extend and contract. Adapted,
The lower end of the first part 1 is in a non-contacting manner with at least part of the inner and outer skin surfaces Ls of the Achilles tendon T on the rear surface Lr of the lower end Le of the lower leg L in a stretched state in a stationary standing position while being worn. A feature is that a moment M in the buckling direction D1 is applied to the foot F around the heel An at the rear Db of Le.

The first part is at least partly non-contacting with the inner and outer skin surfaces of the Achilles tendon on the posterior surface of the ankle, so that the first part is arranged at a position far from the heel and the arm of the moment of the first part Can be increased in the bottom flexion torque.
In particular, although the first part has a large elastic modulus in the longitudinal direction, it is non-contact at least partially with respect to the skin surface on the rear surface of the ankle as described above. It will hardly tighten. As a result, the free movement of the ankle joint group will not be hindered, and the performance and the feeling of wearing will be improved.

The exercise wear according to the second aspect of the first invention includes a first portion 1 that continuously extends from the sole Fb through the rear surface Fr of the foot F along the rear surface Lr of the lower end Le of the lower leg L,
A second part 2 adapted to cover the front face Lf of the lower end Le of the lower leg L,
In the wearing state, the first part 1 and the second part 2 extend along the longitudinal direction Dy along the foot F and the lower leg L,
The elastic modulus Ey per unit width of the first part 1 in the longitudinal direction Dy at 50% elongation is greater than that of the second part 2, where
The rear surface Lr of the lower leg L in an area at least 1/4 of the longitudinal direction Dy is upwardly covered from the lower end A2e of the outer fruit A2 of the lower leg L so that the first part 1 can extend and contract. Adapted,
The first part 1 is in a stretched state of standing still while being worn so that a moment M in the buckling direction D1 acts on the foot F around the heel An at the rear Db of the lower end Le of the lower leg L. Configured,
When the elongation of the first part 1 in the longitudinal direction Dy is 50%, the first part 1 is a member that exhibits elastic deformation.

In this aspect, “when the elongation in the longitudinal direction of the first part is 50%, the first part exhibits elastic deformation” means that the substantial elastic limit is 50% or more. Unlike a metal, in the case of a fiber such as a woven fabric, a slight permanent deformation tends to occur after the stress is removed. Therefore, it should be understood that the present invention includes a case where a permanent deformation of 5% or less remains. Small permanent deformations as small as 5% will not hinder the elasticity of the first part. Therefore, it is unlikely that the feeling of wearing or bottom flexion will be reduced.

While running, the foot repeats a bottom flexion of about 50 ° and a dorsiflexion of about 20 °. During this travel, it has been confirmed that the first part changes in elongation by about 50% at the lower end Le of the lower leg. Therefore, when the elastic limit is 50% or more, the first part can extend 50% during the running and the first part can exert the buckling torque.
For this reason, the elastic modulus Ey is a value at 50% elongation (standard).

More preferably, the substantial elastic limit is 80% to 3000%. Further, the material of the first part generates a buckling direction torque when shrinking, and therefore it is preferable to have rubber-like elasticity with a large energy during shrinkage. In this case, even when the foot has the maximum bottom flexion with a small extension of the first part, a force that gives a bottom flexion torque to the foot and strongly kicks the road surface will be generated.

The exercise wear according to the third aspect of the first invention includes a cylindrical cylindrical portion 3 extending in the longitudinal direction Dy,
The cylindrical part 3 is adapted to cover the rear surface Lr of the lower end Le of the lower leg L in an extended state;
A second part 2 adapted to cover the front face Lf of the lower end Le of the lower leg L,
In the wearing state, the first part 1 and the second part 2 extend along the longitudinal direction Dy along the foot F and the lower leg L,
The elastic modulus Ey per unit width of the first part 1 in the longitudinal direction Dy at 50% elongation is greater than that of the second part 2, where
The rear surface Lr of the lower leg L in an area at least 1/4 of the longitudinal direction Dy is upwardly covered from the lower end A2e of the outer fruit A2 of the lower leg L so that the first part 1 can extend and contract. Adapted,
The first part 1 is in a stretched state of standing still while being worn so that a moment M in the buckling direction D1 acts on the foot F around the heel An at the rear Db of the lower end Le of the lower leg L. Configured,
The distal end 1E of the first part 1 is arranged between the arch FA and the heel H of the foot F.

In this case, the plantar buckling torque will be exerted even in a stationary position, so that the impulse to kick the road surface will increase.

In particular, the distal end 1E of the first part is disposed between the arch and the heel, and the first part is not disposed in front of the arch. Therefore, there is no possibility that the first fabric will compress the foot back and forth, and the feeling of wearing will not decrease.

The second invention is a stocking-like exercise wear,
An annular belt portion 4 disposed at the proximal end portion 4E of the wear and defining a mouth 40;
A cylindrical tubular portion 3 that is continuous with the belt portion 4 and extends downward in the longitudinal direction Dy and defines a hem opening 30;
The tubular portion 3 is adapted to cover the bottom surface Hb of the wearer's heel H, the rear surface Fr of the foot F, and the rear surface Lr of the lower end Le of the crus L in a stretched state,
A second part 2 adapted to cover the front face Lf of the lower end Le of the lower leg L,
The elastic modulus Ey of the first part 1 in the longitudinal direction Dy is larger than that of the second part 2 in the longitudinal direction Dy;
The fold line 11 of the first part 1 in a state in which the wear is folded so that the first part 1 overlaps with each other and the second part 2 overlaps with the second part 2 is formed on the second part 2. Including a first curved line 1c curved to be concave toward the
Including a second curved line 2c that is bent so that the folding line 21 of the second part 2 in a state in which the wear is folded is convex toward the first part 1,
The first curved line 1c is disposed at the distal end 3E of the wear close to the hem opening 30;
The second curved line 2c is disposed at an intermediate portion 31 which is spaced apart from the first curved line 1c in the longitudinal direction Dy and between the distal end portion 3E and the proximal end portion 4E.

The first curved line 1c near the hem opening 30 makes the hem opening 30 small, and the hem opening 30 is easily engaged with the rear half of the foot during wearing. Therefore, a feeling of wearing improves.
On the other hand, the second curved line 2c spaced from the first curved line 1c in the longitudinal direction Dy narrows the tubular portion 3 in the vicinity of the ankle, and the tubular portion 3 is likely to follow the front surface of the lower leg L. Therefore, the feeling of wearing will be improved and increase in air resistance during traveling will be suppressed.

In the method of using the wear of the present invention, the foot F is inserted from the foot 40, a part of the foot F protrudes from the hem opening 30, and the first part 1 at the distal end 3E is the wearer's wear. The belt portion 4 is in a state of being tightened at a constricted portion KC between the knee Kn of the wearer and the calf CA so as to be engaged with the bottom surface Hb of the heel H. Wearing the wear on
And a step of traveling while wearing the wear.

In this case, by running while wearing the wear, the first part 1 of the wear worn during the running is worn at least on the part covering the rear surface of the lower end Le of the lower leg L and the bottom surface Hb of the heel H. A moment M in the bottom bending direction is applied around the person's heel An. Therefore, the driving force when kicking the road surface will increase and the driving performance will improve.

In the first aspect, preferably, the first part 1 is not in contact with the skin surface Ls at least at a part immediately behind the Achilles tendon T.
As described above, when the skin surface is not in contact with at least a part immediately behind the Achilles tendon T, the plantar flexion torque is increased, and the free movement of the ankle joint group is not easily disturbed.

  Preferably, the elastic modulus Er of the second portion 2 in the circumferential direction Dr is smaller than that of the first portion 1 when stretched in the circumferential direction Dr intersecting the longitudinal direction Dy by 50%. That is, the elastic modulus of the first part 1 at the time of 50% expansion in the circumferential direction Dr intersecting the longitudinal direction Dy is larger than the elastic modulus Er of the second part 2.

If the tightening force in the circumferential direction of the lower leg or foot by the fabric is excessive, the movement of the muscles and tendons of the lower leg or foot is hindered. In this regard, in the case of this preferred embodiment, the elastic modulus in the circumferential direction of the second part when stretched by 50% is smaller than that of the first part, so that the free movement of the lower leg and leg muscles and tendons are not easily hindered. .
On the other hand, if the wear is not fitted to the lower leg, the air resistance is increased and the wearing feeling is deteriorated. In this regard, in the case of this preferred mode, the second part will easily fit the lower leg due to the first part having a large elastic modulus in the circumferential direction.

Preferably, the first part 1 has a length of at least 8 cm in the longitudinal direction Dy in a non-loading and non-wearing state, and the value of the tensile load W at which the first part 1 of 8 cm extends by 4 cm is increased by 4 cm. The value Cs divided by λ is 1.0 N / cm-4.8 N / cm.

The value Cs corresponds to the spring constant of the 8 cm portion. 1 kgf = 9.8 N, and the equivalent value Cs of the spring constant is significantly smaller than the value that is preferable in the preceding example, and therefore, it is easy to allow the dorsiflexion action of the foot that naturally occurs during running. Therefore, a feeling of wearing is remarkably improved.

When the value Cs is smaller than 1.0 N / cm, the force to bend the foot is insufficient, and the increase in the bottom bending force tends to be insufficient. On the other hand, when the value Cs exceeds 4.8 N / cm, it may be difficult to raise the toe and the feeling of wearing may deteriorate.

Preferably, the elastic modulus Ey in a state where the first part 1 is stretched 50% in the longitudinal direction Dy is 0.5 N / cm-4.8 N / cm.

When the value of the elastic modulus Ey is smaller than 0.5 N / cm, even if the circumferential width of the first part 1 is increased, the equivalent value Cs of the spring constant tends to be smaller than 1.0 N / cm. On the other hand, when the value of the elastic modulus Ey is larger than 4.8 N / cm, the equivalent value Cs of the spring constant is likely to be larger than 4.8 N / cm even if the circumferential width of the first portion 1 is decreased. .

  Preferably, the elastic modulus Er in a state where the second portion 2 is stretched 50% in the circumferential direction Dr is 0.0001 N / cm-0.5 N / cm.

A material having an elastic modulus Er of less than 0.0001 N / cm will be too stretched and difficult to use. If the elastic modulus Er is greater than 0.5 N / cm, the wear will tend to hinder free movement of the ankle and ankle joint.

Preferably, the distal end 1E of the first part 1 is disposed between the arch FA of the foot F and the heel H.

  When the distal end 1E of the first part is disposed between the arch FA and the heel H, the tension of the first part 1 acting on the heel H in the heel H is directed toward the rear Db of the foot. Therefore, the plantar flexion torque can be exhibited also in the sole Fb.

  The first portion 1 that does not cover the arch of the foot to the tip of the toe does not greatly curve the joint between the phalanges of the toe. Further, the first part 1 does not apply a compressive force to the arch between the toe and the heel, and there is no fear that the foot arch is deformed so as to be convex upward. These significantly improve the feeling of wear and exercise performance.

In this 1st invention, Preferably, the tension | tensile_strength of the said longitudinal direction Dy of the said 1st part 1 in 50% elongation is 4N or more,
The tension in the longitudinal direction Dy of the first part 1 at an elongation of 50% is 19.2 N or less.

As can be seen from the results of the sensory test described later, when the tensile load W is smaller than 4N, there is a case where the force to bend the foot is insufficient, and the increase in the bottom bending force may be insufficient. right. On the other hand, if the tensile load W exceeds 19.2 N, it may be difficult to raise the toe and the wearing feeling may be reduced.

In the first invention, preferably, the athletic wear is in a stocking shape,
An annular belt portion 4 disposed at the proximal end portion 4E of the wear and defining a mouth 40;
A cylindrical tubular portion 3 which is continuous with the belt portion 4 and extends downward in the longitudinal direction Dy and defines a hem opening 30 at the distal end portion 3E of the wear;
The tubular part 3 includes the first part 1 and the second part 2.

In this case, this wear as stockings can be worn in combination with other wear.

The stocking-like wear is adapted so that the hem opening 30 is arranged between the arch of the foot F and the heel H.

In this case, the distal end 1E of the highly elastic first part 1 is also disposed between the arch FA and the heel H. When the distal end 1E is disposed between the arch FA and the heel H, the tension of the first part 1 acting on the heel H is directed toward the rear Db of the foot. Therefore, the plantar flexion torque can be exhibited also in the sole Fb.

  In general, the perimeter of the foot changes from the arch toward the heel H. Therefore, the hem opening 30 disposed between the foot arch FA and the heel H is easily engaged with the foot, and the wearing state of the wear is stabilized.

Preferably, the first part 1 is composed of a first fabric in which the warp 1f extends in the longitudinal direction Dy,
When the elongation of the warp 1f is 50%, the warp 1f has elasticity that exhibits elastic deformation.

The first part 1 can be made of various materials such as a woven fabric, a knitted fabric, and a film-like stretchable sheet. When the woven fabric is composed of warp 1f having a large elastic limit, the first part 1 expands and contracts using the stretchability of the warp 1f, and therefore, unlike the knitted structure of the knitted fabric, it is easy to expand and contract in the longitudinal direction Dy, and The expansion / contraction speed is large, and the expansion / contraction speed is hardly delayed with respect to the traveling cycle.

Preferably, the second part 2 is composed of a second fabric.
In the stitched portion 5 extending in the longitudinal direction Dy, the first portion 1 and the second portion 2 are continuous with each other in the circumferential direction Dr.
In this case, the degree of freedom of design is remarkably improved by using two kinds of fabrics having greatly different elasticity.

Preferably, the belt part 4 is adapted to be arranged between the knee Kn and the calf CA.
In this case, the belt portion engages with the constricted portion of the leg between the knee Kn and the calf CA. Therefore, it is difficult for the first part 1 to shift and fall, and the bottom bending torque due to the first part 1 is easily exhibited.

Preferably, in a region 32 from the intermediate point Oc between the foot opening 40 and the hem opening 30 to the hem opening 30, the ratio of the second portion 2 to the entire circumference in the circumferential direction Dr in an unloaded state is 40. It is set to ~ 80%.

If the ratio is less than 40%, the moments around the heel may be offset. On the other hand, if the ratio exceeds 80%, the bottom bending force due to the first part tends to decrease.

Preferably, the hem opening 30 is formed such that the edge of the distal end 2E of the second part 2 is curved in a convex shape upward when the wear is not worn.

In this case, the first part 1 is longer than the second part 2. Thereby, along the short line of the leg from the leg, the second part 2 fits to the leg and the leg, while the length of the first part 1 passing from the sole to the back of the heel can be sufficiently secured. Therefore, a stable wearing feeling and bottom bending torque can be exhibited.

Preferably, a slip-preventing member is provided on the inner surface of the distal end portion 3E of the member of the first portion 1.

Since the 1st part 1 is pulled up upwards at the time of wear | wearing of a wear, there exists a possibility that the distal end part 3E of the 1st part 1 may slip | deviate toward the back of a heel. On the other hand, when the member for slip prevention is provided in the distal end portion 3E, the shift can be suppressed. Therefore, the wearing state is stabilized.

Further, the slip-preventing member provided at the distal end portion 3E is also engaged with the socks and the soles, and a moment in the bottom bending direction is likely to occur even at the bottom surface of the heel. Therefore, it is easy to obtain a bottom bending torque larger than the preceding example in which the feet are covered with a highly elastic material.

The wear can be used as follows.
That is, the foot F is inserted from the foot opening 40, a part of the foot F protrudes from the hem opening 30, and the first portion 1 of the distal end portion 3E is related to the bottom surface Hb of the wearer's heel H. The step of wearing the wear so that the belt portion 4 is in a state where the constricted portion KC between the knee Kn of the wearer and the calf CA is tightened so as to be in a combined state. When,
And a step of traveling while wearing the wear.

  In a preferred method of use, in the step of wearing, the moment in the buckling direction D1 around the wearer's heel An at a portion where the first portion 1 of the wear covers at least the rear surface Lr of the lower end portion Le of the lower leg L. The first part 1 is worn in an extended state so that M acts.

In a preferred method of use, the method further comprises the step of previously wearing the socks 6 that wrap the legs F of the wearer,
The wear is worn after the sock 6 is worn.
In this case, socks according to the wearer's preference can be worn separately from the wear.
In this case, the anti-slip member may be provided on the outer surface of the sock instead of the wear.

Features described and / or illustrated in connection with one such embodiment or each of the following examples may be in the same or similar form in one or more other embodiments or other examples, and / or It can be utilized in combination with or instead of the features of other embodiments or examples.

The invention will be more clearly understood from the following description of preferred embodiments with reference to the accompanying drawings, in which: However, the examples and drawings are for illustration and description only and should not be used to define the scope of the present invention. The scope of the present invention is defined only by the claims. In the accompanying drawings, the same part numbers in a plurality of drawings indicate the same or corresponding parts.

The wearing state of this wear is demonstrated.
In FIG. 1A, the wear is in a stocking shape and includes a cylindrical portion 3 and a belt portion 4.

As clearly shown in FIG. 3, the belt portion 4 has an annular shape and is disposed at the proximal end portion 4 </ b> E of the wear to define a mouthpiece 40. The tubular portion 3 is tubular and extends downward in the longitudinal direction Dy of FIG. 5A in a continuous manner with the belt portion 4 and defines the hem opening 30 of FIG. 3 at the distal end portion 3E of the wear. The tubular part 3 includes a first part 1, a second part 2 and a stitched part 5.

The belt portion 4 in FIG. 1 has elasticity, and fastens the upper end of the lower leg L in the circumferential direction to fix the wear to the lower leg L. The belt portion 4 is adapted to be disposed between the knee Kn and the calf CA.

In FIG. 1, the first portion 1 extends from the sole Fb through the rear surface Fr of the foot F along the lower surface portion Lr of the lower leg L and is inflated above the calf CA. Extends continuously. The second portion 2 is adapted to cover a part of the instep and the front surface of the ankle to the front surface Lf of the lower end portion Le of the lower leg L and the lower end of the belt portion 4 along the shin.

In the wearing state, the first part 1 and the second part 2 extend along the longitudinal direction Dy along the foot F and the lower leg L. The elastic modulus Ey per unit width of the first part 1 in the longitudinal direction Dy at the time of 50% elongation is larger than that of the second part 2.

In the case of this example, the first part 1 is constituted by the first woven fabric in which the warp yarns 1f of FIG. 5A and FIG. 5B extend in the longitudinal direction Dy, and the second part 2 has a second warp yarn 2f extending in the longitudinal direction Dy. It is composed of 2 fabrics. In the stitched portion 5 extending in the longitudinal direction Dy, the first portion 1 and the second portion 2 are connected to each other in the circumferential direction Dr as shown in FIGS. 1B and 1C.
When the elongation of the warp yarns 1f and 2f in FIG. 5A is 50%, the warp yarns 1f and 2f have elasticity that exhibits elastic deformation, respectively.

An auxiliary belt portion 42 connected to the belt portion 4 of the lower leg L may be provided so that the present wear of FIG. 1A can be easily fixed to the lower leg L. The auxiliary belt portion 42 constitutes a part of the front body. For example, the same material as the first portion 1 may be used. Similarly, the first portion 1 or the second portion 2 and the auxiliary belt portion 42 are connected by the stitching portion 5. The auxiliary belt part 42 may be disposed above the thickest part of the calf.

The distal end 1E of the first part and the distal end 2E of the second part of the skirt opening 30 are adapted to be disposed between the arch FA of the foot F and the heel H. In the case of this example, the skirt opening 30, the first portion distal end 1E, and the second portion distal end 2E are disposed between the first Lisfranc joint Jr to the heel H. The bottom opening 30 is subjected to a known terminal process.

As in this example, the first part 1 may be provided over the entire length of the lower leg L below the belt part 4. The rear surface Lr of the crus L in the region L1 of at least ¼ in the longitudinal direction Dy, more preferably in the region L2 of at least ３, upward from the lower end A2e of the outer fruit A2 in the crus L in FIG. The first part 1 may be adapted to cover in a stretchable state.

In the case of this example, as shown in FIG. 1A and FIG. 1C, the first part 1 is in a stretched state in a stationary standing state while being worn. In addition, the moment M in the buckling direction D1 is applied to the foot F around the heel An at the rear Db of the lower end Le without contacting at least a part of the outer skin surface Ls. That is, the tension acting on the first part 1 exerts a force for pulling up the heel H upward, and generates a moment M in the bottom bending direction D1.

In a state where the first part 1 is stretched in a stationary position while being worn, the frictional force of the first part 1 acting toward the rear Db acts on the bottom surface Hb of the heel H, and thereby the moment in the bottom bending direction D1. M is generated around the inner fruit A1 (踝 An).

In the case of this example, a slip-fastening member 7 is provided on the inner surface of the distal end portion 3E of the member of the first portion 1. Therefore, the moment M acting on the bottom surface Hb of the heel H can be increased.

The structure of the wear when not worn will be described.
In the case of this example, the inner surface side of FIG. 5A and the outer surface side of FIG. 5B are substantially mirror-symmetric (axisymmetric) shapes.

5A and 5B show a state in which the wear is folded so that the first part 1 is overlapped and the second part 2 is overlapped. The folding line 11 of the first part 1 in this state includes a first curved line 1c that is curved so as to be concave toward the second part 2. On the other hand, the folding line 21 of the second part 2 in a state in which the wear is folded includes a second curved line 2c that is curved so as to be convex toward the first part 1.

The first curved line 1 c is disposed at the distal end portion 3 </ b> E of the wear near the skirt opening 30. The second curved line 2c is disposed at an intermediate portion 31 which is spaced apart from the first curved line 1c in the longitudinal direction Dy and between the distal end portion 3E and the proximal end portion 4E.

The outer angle θ1 formed by the first curved line 1c is preferably about 190 to 225 degrees, and more preferably 190 to 210 degrees. On the other hand, the outer angle θ2 formed by the second curved line 2c is preferably about 135 to 150 degrees. This is because the first part 1 is easy to fit the thinnest part of the lower leg L. Moreover, it is generally preferable that θ1> θ2.

As shown in FIGS. 6A to 6C, as clearly shown particularly in FIG. 6B, the present wear includes an intermediate portion 31 between the proximal end portion 4 </ b> E and the first distal end 1 </ b> E. The wear has the largest width W1 at the proximal end portion 4E, and the smallest width W4 at the hem opening 30.
The maximum width W3 of the distal end portion 3E of the cylindrical portion 3 is larger than the minimum width W2 of the intermediate portion 31. As a result, it is possible to prevent a large dubbing of the wear on the ankle or the heel.

As shown in FIG. 6B, the hem opening 30 is formed such that the edge of the distal end 2E of the second part 2 is curved upwardly in a state where the wear is not worn. Therefore, in the front view of FIG. 6B, the inner surface of the first part 1 is slightly visible.

5A and 5B, the width of the first part 1 may gradually increase from the intermediate part 31 toward the distal end part 3E. Conversely, the width of the second portion 2 may gradually decrease from the intermediate portion 31 toward the distal end portion 3E.
As shown in FIG. 1A and FIG. 2, the second part 2 greatly stretches in the circumferential direction when worn, and the length of the second part 2 in the circumferential direction from the thickest part of the calf CA to the heel An Is larger than the circumferential length of the first part 1. Thereby, it is suppressed by the highly elastic 1st part 1 that a leg is tightened in the circumferential direction, and a wear feeling improves.

As shown in the wearing state of FIG. 1A and FIG. 2, the distal end portion 3E of the first portion 1 having a large width covers not only the bottom surface Hb of the heel H but also the side surface of the heel H. Thereby, the stitching | suture part 5 is arrange | positioned at the side surface of the heel H where load is hard to be applied.
The front edge of the first part 1 may be arranged behind the center of the outer fruit A2 in FIG. 2 or the center of the inner fruit A1 in FIG. 1A. This is for generating a moment M in the buckling direction D1 around the flange An.

  Next, the operation of the foot flexion while running will be described.

  As shown in FIG. 15A, at the time of plantar flexion of the foot, the foot F rotates downward around the rotation center Ao of the heel An so that the toes are below the bottom of the heel H. On the other hand, as shown in FIG. 15B, when the foot is dorsiflexed, the foot F rotates upward around the rotation center Ao of the heel An so that the toe is above the bottom of the heel H.

  FIG. 14A shows time series data of bottom buckling torque at the time of running at high speed. As shown in the figure, it can be seen that during a high-speed running operation, a force is always exerted in the plus direction, which is the bottom bending direction, and no force is exerted in the dorsiflexion direction.

  FIG. 14B shows changes in the angle of plantar flexion during running at high speed. Between the ground contact and the takeoff during traveling, the foot once bends to about 20 ° due to the inertia of the forward leaning posture immediately after the ground contact. After that, the legs buckle to about 50 ° until they reach the ground.

  Therefore, in order to increase the running speed, from the ground contact to the takeoff, that is, between the dorsiflexion 20 ° and the dorsiflexion 50 °, the sole is given a buckling torque to increase the impulse to kick the road surface. It turns out that is important.

Next, test samples and test results before the inventors produce the wear of this embodiment will be described.
A rubber band that expands and contracts in the vertical direction was placed on the back of a commercially available stocking, and was set so that the wearer's feet always received torque in the buckling direction. 3 adult male subjects, 24 (km /
h) The ground reaction force during running was measured. As a result, the impulse, which is a force for kicking the road surface, increased by about 20% in the case of having a rubber band as compared to the case of a normal stocking without a rubber band.

Next, sensory tests and results based on VAS (Visual Analog Scale) conducted by the present inventors will be described.
This test was performed in order to know preferable values of the elastic modulus Ey in the longitudinal direction Dy and the elastic modulus Er in the circumferential direction Dr of the first part 1 of the wear shown in FIG.

  Using the stockings of Example 1 of FIGS. 1A to 6C, changing the height of the belt part 4 so that the stretch of the fabric of the first part 1 is about 15% to 140% in a stationary position, the subject (subject ) Worn by AE.

13A to 13E show the results of the sensory test.
In these figures, the vertical axis indicates the score of the following two items.
(1) Did you feel tension in the bottom flexion direction?
(2) Did you feel it difficult to raise your toes?

  Focusing on the values indicated by the white squares in FIGS. 13A to 13E, when the elongation of the first part 1 in the standing position exceeds 100%, for example, the bottom like the testers A, B, C, and E It was difficult to feel the difference in force in the bending direction.

  Further, when paying attention to the black circles of FIGS. 13A to 13E, when the elongation of the first part 1 in the standing position exceeds 100%, it was difficult to raise the toes like the subjects C, D, and E.

  FIG. 12A shows the load per unit width with respect to the elongation of the first part in the longitudinal direction. As can be seen from FIG. 12A, the tension per unit width when the elongation is 100% is about 2.4 N / cm, while the width of the first part 1 is about 8 cm. Therefore, in the stationary standing position, the tension in the longitudinal direction Dy of the first part 1 at 50% elongation is preferably 2.4 N / cm * 8 cm = 19.2 N or less.

  The first part 1 (FIG. 1) has a length of at least 8 cm in the longitudinal direction Dy in an unloaded and non-wearing state, and the value of the tensile load W at which the first part 1 of 8 cm extends by 4 cm is 19.2N. The equivalent value Cs of a spring constant obtained by dividing the above by 4 cm elongation λ is preferably 19.2 N / 4 cm = 4.8 N / cm or less.

  The elastic modulus at 100% elongation in FIG. 12A is about 2.4 N / cm obtained by dividing 2.4 N / cm by 100%. However, the width 1W of the first part 1 can be set as small as about 4 cm as shown in FIG. 8C. Therefore, the elastic modulus Ey at 50% elongation is preferably 4.8 N / cm or less.

  Paying attention to the values indicated by the white squares in FIGS. 13A to 13E, when the elongation of the first part 1 in the standing position is less than 25%, for example, as in subjects C and D, It was hard to feel the power.

The time of 25% in FIG. 12A is the time when the foot moves toward the plantar flexion direction, and the value when the test piece contracts should be used. Therefore, the tension per unit width is about 0.5 N / cm. It is. On the other hand, the width of the first part 1 is about 8 cm, and therefore the tension in the longitudinal direction Dy of the first part 1 at 50% elongation is preferably 0.5 N / cm * 8 cm = 4 N or more.
The first part 1 has a length of at least 8 cm in the longitudinal direction Dy in an unloaded and non-wearing state, and the value of the tensile load W at which the first part 1 of 8 cm extends by 4 cm is divided by the elongation λ of 4 cm. The equivalent value Cs of the spring constant is preferably 4 N / 4 cm = 1.0 N / cm or more.

  As can be seen from FIG. 12B and FIG. 12D, the elastic modulus Er in the circumferential direction Dr of the second part 2 is that of the first part 1 with respect to the elastic modulus in the circumferential direction Dr that intersects (orthogonally) the longitudinal direction Dy. Smaller than that. For example, the elastic modulus Er in a state where the second portion 2 is stretched 50% in the circumferential direction Dr is preferably about 0.0001 N / cm-0.5 N / cm.

Next, various tests performed by the present inventors will be described.
The inventor measured the relationship between the angle of the sole dorsiflexion of the foot and the elongation (rate) of the first part 1 of the wear by the following method. The subject wore wear, and the elongation of the first part 1 of the wear at 20 degrees dorsiflexion and 50 degrees buckling in a standing position was measured with a color image. As a result, at the lower end Le of the lower leg L, the first part 1 was greatly stretched, about 80% elongation was observed at 20 degrees dorsiflexion, and about 30% elongation was observed at 50 degrees buckle.

Next, the relationship between the bottom dorsiflexion angle and the elongation of the first portion 1 of the wear will be described in an easy-to-understand manner with reference to FIGS. 7A to 7D.
First, as shown in FIG. 7A, marks N1 to N13 were attached at equal intervals to the first part 1 of the wear serving as a test sample, and a digital image of the wear was captured. Next, the subject wore the wear, and digital images were taken in the bottom bent position (50 degrees) in FIG. 7B, the stationary position in FIG. 7C, and the dorsiflexed position (20 degrees) in FIG. 7D.

  7B to 7D, the first region L1 is a region of about ¼ of the longitudinal direction Dy from the lower end A2e (FIG. 15C) of the outer fruit A2 of the lower leg L upward. On the other hand, the second region L2 is a region of about 1/3 of the longitudinal direction Dy from the lower end A2e (FIG. 15C) of the outer fruit A2 of the lower leg L upward.

  As can be seen from these drawings, it can be seen that the first and second regions L1 and L2 have a larger extension of the first portion 1 than the region above the mark N8. In particular, it can be seen that the first region L1 above the lower end A2e of the outer fruit A2 is further expanded and contracted.

  Here, the first and second regions L1 and L2 are about 8 cm or about 12 cm in length at points N2-N6 and N2-N8 in FIG. 7A, respectively. Further, the point N2 when worn corresponds to the lower end A2e (of the external fruit A2) of the rib B20 in FIG. 15C.

  In FIG. 15C, the radius B20 and the tibia B10 constitute a part of the lower leg L (FIG. 1). The lower leg L means from the lower end A2e of the radius B20 (external fruit A2) to the position of the upper end of the tibia B10 (under the knee).

Next, an example of how to use the wear will be described.
First, the socks 6 that wrap the legs F of the wearer in FIG. 1 are worn in advance. The wear is worn as follows after the sock 6 is worn.

That is, the foot F is inserted from the foot opening 40, a part of the foot F protrudes from the hem opening 30, and the first portion 1 of the distal end portion 3E is related to the bottom surface Hb of the wearer's heel H. The wear is worn such that the belt portion 4 is in a state where the constricted portion KC between the knee Kn of the wearer and the calf CA is tightened. At this time, the first part 1 is pulled in the longitudinal direction Dy so that the first part of the wear is stretched by about 50% in a stationary position.

That is, the moment M in the buckling direction D1 is applied around the wearer's heel An on the portion where the first portion 1 of the wear covers the rear surface Lr of the lower end Le of the lower leg L and the bottom surface Hb of the heel H. Thus, it wears in the state where the 1st part 1 extended. Drive with the wear on.

During the running, the sprinter generally touches the heel without touching the heel and leaves with the toe, but the present invention is also applied to the case where the heel is touched.

During the running, as shown in FIG. 7B to FIG. 7D and FIG. 14B, the cycle of plantar flexion-dorsiflexion-basal flexion is repeated. At this time, the wear gives the foot a moment M in the plantar flexion direction D1. Therefore, the motor function is improved.

Next, another example will be described.
As shown in FIGS. 8A to 8D, when the first part 1 is a material such as a stretchable film, it may be attached to the outer surface or the inner surface of the base fabric with a stretchable adhesive. As shown in FIGS. 9A to 9D, the length of the first portion 1 when not worn may be, for example, about 8 cm to 16 cm.

In these cases, as shown in FIGS. 8E to 8H, the circumferential lengths of the first part 1 and the second part 2 can be set to various lengths. For example, in the region 32 from the midpoint Oc between the foot opening 40 and the hem opening 30 to the hem opening 30 in FIG. 9A, the ratio of the first part 1 to the entire circumference in the circumferential direction in the no-load state is 8E to 8H, the ratio may be set to about 20 to 60%. In this case, the ratio of the second portion 2 to the entire circumference in the circumferential direction may be set to about 40 to 80%. .

8A to 8D and FIGS. 9A to 9D, the first part 1 is provided with a dot pattern, and the dots are shown more densely as the elastic modulus Ey is larger.
As shown in FIG. 8A, when the first part 1 is large in the longitudinal direction Dy and the circumferential direction Dr, the elastic modulus Ey of the first part 1 is set to a small value. On the other hand, as shown in FIG. 8C, when the first part 1 is small in the longitudinal direction Dy and the circumferential direction Dr, the elastic modulus Ey of the first part 1 is set to a large value.

In the case of FIGS. 9A to 9D, a member having a larger or smaller elastic modulus in the vertical direction than that of the first part 1 may be disposed above or below the first part 1 in the back body.

In the wear of FIG. 10A, the first part 1 and the second part 2 are composed of a knitted fabric. Also in this case, it is preferable that the warp yarns 1f and 2f in FIGS. 10B and 10C are elastic yarns as in the woven fabric. In this example, the thread 1 f of the first part 1 is thicker than the thread 2 f of the second part 2. Note that the two-dot chain line in FIG. 10A indicates the boundary between the first part 1 and the second part 2.

As in the example of FIG. 11, the wear may cover the toes as in ordinary stockings. Even in this case, it is desirable that the distal end 1E of the first portion 1 is disposed between the foot arch FA and the heel H. The instep and toe may be covered with the same material as the second part 2.

As the slip stopper 7 shown in FIG. 6A and FIG. 6C, it is possible to employ one that prints a small bulge by rubber such as silicone or various thermoplastic resins. In this case, the slip stopper 7 may have a dot shape, or a line shape or a lattice shape.

Further, as the slip stopper 7, a nanofiber fabric or a male fastener may be attached to the corresponding portion instead of the silicone print or the like.

As described above, the preferred embodiments have been described with reference to the drawings. However, those skilled in the art will readily see various changes and modifications within the obvious scope by looking at the present invention.
A vent hole may be provided in the front body formed by the second part.
Further, the front body portion may be belt-shaped.
The first part may be formed by impregnating the dough with resin, while the second part may be formed by dissolving the resin impregnated into the dough.
It may be a tights with the proximal end up to the waist or a tether connected to the tops.
Accordingly, such changes and modifications are to be construed as within the scope of the present invention as defined by the claims.

  The present invention can be applied to athletic clothing such as stockings and tights.
