Description

  In particular, the present invention relates to leg wear that is useful for restraining O-legs, supporting sports, and the like.

  Many elderly women have knee pain caused by O-leg deformation, which is a problem. Therefore, conventionally, techniques for guiding the knee inward have been proposed.

  For example, Patent Literature 1 proposes a cylindrical knee support that surrounds a knee joint for correcting varus deformity. This supporter includes a belt-like portion that applies a tightening force in a direction in which the small head of the rib is directed to the inner side of the leg in a state where the main body portion is mounted. As a result, the rib head that is displaced outward is pressed inward to correct the varus deformity.

  Patent Document 2 and Patent Document 3 propose a crotch garment that covers from the waist part to the upper part of the thigh part so that the knee can be easily directed inward. The crotch garment described in Patent Document 2 includes a main adductor that covers a body portion covering from the waist to the upper part of the thigh, and a site where the major adductor muscle having a stronger tightening force than the main body portion is located. A support part and a non-stretch side armor part covering the side of the thigh and partially adjoining the greater adductor support part are provided. The crotch garment described in Patent Document 2 expands and contracts along the greater adductor muscle with the greater adductor muscle support portion in close contact with the thigh.

  The crotch garment described in Patent Document 3 includes a main body that covers from the waist to the upper part of the thigh, and a support line that covers a portion where the greater adductor muscle having a tightening force stronger than the main body is located. I have. The support line portion is spirally connected from the position corresponding to the outside of the front line in the longitudinal direction of the femur to the position corresponding to the rear side of the thigh and outside the inner end of the groin. Yes. As a result, a tightening force is generated by the support line portion at the portion corresponding to the inside of the thigh where the skin greatly expands in accordance with the movement of the wearer.

  Moreover, the legware which concerns on this invention WHEREIN: It is preferable that a said 1st side surface is an outer side surface of a rib upper end, and a said 2nd side surface is an outer side surface of a rib lower end in the said 1st crus tightening part.

  According to the above configuration, the lower leg is pulled by the first lower leg tightening portion from the outer side of the knee to the inner side so that the lower leg part rotates outwardly. Thereby, the valgus moment of the knee joint can be suppressed and the swaying of the knee can be braked. As a result, it is possible to brake the internal rotation of the knee without excessive pressure and tightening.

  The legwear according to the present invention is a belt-like second shape formed so as to pass from the medial side surface of the upper tibia to the front surface of the tibia and the radius, the posterior surface of the tibia and the radius, and the medial side surface of the lower end of the tibia. It is preferable that a crus tightening portion is provided, and the tightening force of the first crus tightening portion is stronger than the tightening force of the second crus tightening portion.

  According to the above configuration, since the second crus tightening portion guides the crus in the internal rotation direction with a weaker force than the first crus tightening portion, the first crus tightening portion excessively rotates the crus externally. Can be suppressed.

  In the legwear according to the present invention, it is preferable that a width of the first crus tightening portion is wider than a width of the second crus tightening portion.

  According to the above configuration, the tightening force of the first crus tightening portion can be made stronger than the tightening force of the second crus tightening portion by widening the band of the tightening portion.

  Further, in the legwear according to the present invention, the first crus tightening portion and the second crus tightening portion intersect at the center part in the width direction of the crus at the front surface of the tibia and the rib, and the rear surface of the tibia and the rib In this case, it is preferable to intersect at the center in the width direction of the lower leg.

  According to the above configuration, the lower leg can be internally rotated with a good balance.

  In the legwear according to the present invention, it is preferable that the first crus tightening portion is connected to a knee joint tightening portion formed so as to surround the periphery of the patella.

  According to the above configuration, since the knee joint tightening portion is formed so as to surround the knee joint, the knee joint can be braked. In addition, since the first crus tightening portion is connected to the knee joint tightening portion, it is possible to enhance the club moment suppressing effect due to the internal rotation of the knee joint.

  Further, the legwear according to the present invention includes a thin muscle tightening portion that further covers the thigh, has a tightening force along the muscle direction of the thin muscle, and is connected to the knee joint tightening portion.

(Embodiment 1)
An embodiment of the present invention will be described below with reference to FIGS. In this embodiment, the case where the legware according to the present invention is applied to spats will be described as an example. However, the present invention is not limited to spats, and can be suitably applied to tights, cylindrical supporters, long socks, and other various legwear.

(Onset of pain in knee osteoarthritis)
First, the onset of pain in knee osteoarthritis will be described based on FIG. 3 and FIG. FIG. 3 is a diagram for explaining knee pain caused by O-leg deformation. (A) of FIG. 13 is a figure explaining the bone of a leg.
3A is a view showing the leg in the O-leg state, and FIG. 3B to FIG. 3D are partial enlarged views of the knee joint in FIG. 3 (b) shows the state of a normal knee joint, FIG. 3 (c) shows the initial to middle stage of knee osteoarthritis, and FIG. 3 (d) shows the knee osteoarthritis. Shows the state of progression.

  In general, Japanese have many O-legs of the varus knee as shown in FIG. If the condition of O-deformation continues, osteoarthritis of the knee develops, causing arthritis and deformation, causing knee pain and the like.

  Specifically, in a normal knee joint, as shown in FIG. 3B, the surfaces of the tibia 22 and the femur 20 of the joint are covered with cartilage 40 made of a highly elastic tissue, and the movement of the joint. Is smooth.

  However, if the state of the O leg continues, the cartilage 40 of the knee joint is worn away, and the interval between the tibia 22 and the femur 20 becomes narrow. As shown in FIG. 3 (c), when the wear of the cartilage 40 has progressed to a certain extent, arthritis is caused by stimulation of bending and stretching of the knee, an increase in the burden on the knee during walking, and degeneration of the cartilage 40 and the meniscus. Arise. Arthritis can cause pain when the knee is bent and stretched, and limit bending and stretching.

  Further, as the knee osteoarthritis progresses and the wear of the cartilage 40 progresses as shown in FIG. 3D, the lower bone of the cartilage 40 is exposed or the osteophyte 41 itself is deformed. In this state, hard bones directly collide with each other when the knee is moved or standing and walking, causing strong pain, and the restriction of bending and stretching of the knee becomes high.

  Next, the club moment will be described with reference to FIG. FIG. 4 is a diagram for explaining the club moment. FIGS. 4 (a) and 4 (b) show the state of a normal leg, and FIG. 4 (c) and FIG. 4 (d). ) Shows the state of the O-leg deformed leg.

  The club moment is the amount of force that causes the knee joint 31 to varus due to the distance from the knee joint rotation center to the floor reaction force action line. The floor reaction force action line is indicated by a single arrow in FIG. 4C, and is a line connecting the center of gravity of the foot (middle of the ground contact point of the foot) and the center of gravity Z of the body (around the navel). The knee joint rotation center is the knee joint 31. The distance from the knee joint rotation center to the floor reaction force action line is the distance indicated by the double-headed arrow in FIG. In other words, the club moment is the moment that the knee tends to go outward. When the club moment increases, O-leg deformation occurs.

  As shown in FIG. 4 (a), the femur 20 is disposed between the hip joint 30 and the knee joint 31, and between the knee joint 31 and the ankle joint 32, the tibia 22 is inward and the tibia 22 is outward. Ribs 21 are arranged. In the normal leg state, as shown in FIG. 4 (b), the hip joint 30, the knee joint 31, and the ankle joint 32 are arranged in a straight line while standing upright. Therefore, weight is linearly applied to the knee joint 31 and the ankle joint 32 (arrow A in FIG. 4B), so that no rotational force is applied to the knee joint 31.

  On the other hand, in the state of the O-leg deformation as shown in FIG. 4C, the hip joint 30 is in the upright state as shown in FIG. It is located inside the straight line connecting Therefore, weight is applied to the inside of the knee joint 31 and the ankle joint 32 (arrow A in FIG. 4 (d)), and therefore, the rotational force, that is, the club moment (when the knee is directed to the knee joint 31) The arrow B) in FIG.

  Such weighting from the inside of the knee joint 31 is 90% or more of the causes of osteoarthritis of the knee, and if the club moment increases, the pain of the knee joint 31 also increases. Therefore, in order to reduce knee pain caused by knee osteoarthritis, it is effective to suppress the varus moment. The spats 100 can suppress the club moment by turning the crus inward.

(Schematic configuration of spats 100)
FIG. 1 is a front view when only the left foot tightening portion 10 according to Embodiment 1 of the present invention is taken out. FIG. 2 is a diagram illustrating a state in which the spats 100 are worn. 2A is a front view, FIG. 2B is an inner side view, FIG. 2C is a rear view, and FIG. 2D is an outer side view. In FIG. 2, illustration of each tightening portion of the right foot is omitted. In the present embodiment, in the standing state, the direction in which the user's top is located is referred to as “up”, and the direction in which the user's sole is located is referred to as “down”.

  As shown in FIGS. 1 and 2, the spats 100 include a main body portion 101, a tightening portion 102, and a tightening portion 10. In the present invention, the main body 101 is knitted by a knitting machine, but can also be formed by sewing a fabric woven by a loom.

  As shown in FIG. 2, the main body 101 covers the lower leg, thigh and waist. In other words, the main body 101 covers from the lower back to the lower end of the tibia of the lower leg. The lower leg shows the part from the knee to the ankle. The main body portion 101 is integrally provided with a tightening portion 10 and a tightening portion 102 that have stronger tightening force than the main body portion 101. The tightening force indicates a pulling force, and a tightening force stronger than that of the main body 101 indicates that each of the tightening portions is less stretchable than the main body 101 (other regions). Further, the tightening force of each tightening portion has a pulling force in the longitudinal direction. Thereby, in each tightening part, a taping effect can be produced.

  The tightening portion 10 and the tightening portion 102 can be formed, for example, by adjusting stitches (knitting) in the main body portion 101, changing the type of yarn, changing the material, or bonding the fabric. Specifically, in the present embodiment, for example, the tightening portion 10 uses the same thread as the main body portion 101, and reduces the elasticity by reducing the size of the stitches. As a result, the tightening portion 10 can be formed without forming a thread switching portion that occurs when a thread different from the main body portion 101 is used for the tightening portion 10. For this reason, there is no terminal (step) at the switching point of the yarn, there is no influence on the skin such as a mark of the switching part on the skin, and the fabric feels comfortable even when worn for a long time.

  In addition, as another method of providing each tightening portion, it is possible to change the stitch structure by tack knitting or the like, or to reduce the stretchability by inserting a low stretch yarn, applying a resin or the like. Specifically, for example, when the fabric is bonded to increase the tightening force, each tightening portion is arranged on the inner surface side (skin side) of the main body 101 (base material layer) constituting the spats 100 as a whole. A material having a higher tightening force than other regions can be laminated. In particular, when inserting low stretch yarns or applying resin to the inside of the spats 100, each tightening portion can be provided without deteriorating the aesthetic appearance.

  The main body 101 has a mark (not shown) that allows the user to visually recognize the front and rear of the spats 100 when the spats 100 are worn. Thereby, it becomes easy to wear the spats 100 at an appropriate position.

  The spats 100 are made of a stretchable material. For example, the spats 100 may use warfil (registered trademark of Asahi Kasei Fibers Co., Ltd., composition: cupra 50%, polyester 50%) as a surface yarn material. Using cupra makes it soft and soft to the touch. Further, by making the yarn bulge and smoothing the surface using a filament containing a lot of air, the texture becomes soft and the touch is improved. Moreover, since the surface of the filament is smooth, static electricity hardly occurs. For the spats 100, a material having good air permeability may be used in accordance with the application.

  It is desirable that the main body portion 101 and each tightening portion have the same color and the same material. As a result, knee pain can be reduced while maintaining the appearance close to that of spats worn daily.

  The thickness of the main body 101 can be about 0.02 mm to 0.03 mm. With the configuration of the tightening portion 10 described later, the spats 100 can be provided without deteriorating comfort because an effect of suppressing the varus moment can be achieved even with a thin fabric without excessive pressure and tightening. it can.

  The tightening portion 102 has a semicircular shape whose lower side is an ellipse, and is formed at a position that covers the lower abdomen with the spats 100 attached, and suppresses the lower abdomen.

(Tightening part 10)
As shown in FIGS. 1 and 2, the tightening portion 10 includes a first crus tightening portion 1, a second crus tightening portion 2, a knee joint tightening portion 3, a sewing muscle tightening portion 4, a thin muscle tightening portion 5, and hamstrings. A tightening portion 6 and an inner broad muscle tightening portion 7 are provided.

(1st leg tightening part 1)
The first crus tightening portion 1 has a belt-like shape so as to pass from the first side of the upper end of the tibia or the upper end of the radius, the front surface of the tibia and the radius, the rear surface of the tibia, and the second side of the lower end of the tibia or the lower end of the radius. When the first side is the medial side of the upper end of the tibia, the second side is the medial side of the lower end of the tibia, and when the first side is the lateral side of the upper end of the radius, the second side Is the outer side of the lower end of the rib.

  Specifically, as shown in FIG. 1 and FIG. 2, the first crus tightening portion 1 is attached to the front surface of the tibia and the ribs, the rear surface of the tibia and the ribs, as shown in FIGS. It is formed so as to pass in order and reach the inner side surface of the lower end of the tibia. In other words, the first crus tightening portion 1 is formed in a spiral shape from the inner side of the lower leg near the patella to the inner side of the lower leg near the inner heel via the shin and calf. The first crus tightening portion 1 circulates the crus along the above-described route, thereby causing the crus to rotate inward and guiding the knee inward. The internal rotation of the lower leg means that the lower leg (from the knee to the ankle) rotates inward.

  When the body changes the angle of any bone by interlocking with bone, the alignment of other bones also changes together. For example, if the arch of the sole collapses, the bones will shift to the ankle, knees, and hips in conjunction with it, causing pain in the future.

  The spats 100 cause the lower leg part to rotate internally by the first lower leg tightening part 1. As a result, bone interlocking occurs in which the bone alignment is changed in the direction of closing the O-leg. In other words, the first crus tightening portion 1 can prevent bone interlocking such that the knee faces outward.

  The first crus tightening portion 1 is preferably formed so as to go around the crus. When the first crus tightening portion 1 is formed so as to go around the crus one or more times, the angle between the first crus tightening portion 1 and the ground becomes small, and the pull in the vertical direction becomes weak. Further, when the number of revolutions of the lower leg portion of the first lower leg tightening portion 1 is one or less, the angle with the ground becomes large, and the pulling is performed only in the vertical direction. The width of the first lower leg tightening portion 1 can be, for example, about 1.5 cm to 4.0 cm. The widths of the first crus tightening portion 1 and the second crus tightening portion 2 are made narrower toward the tip of the foot according to the thickness of the foot.

  When the inner side surface of the upper end of the tibia of the first crus tightening portion 1 is the starting point and the inner side surface of the lower end of the tibia is the ending point, the starting point is at least the inner side of the upper end of the tibia when viewed from the side of the inner side of the lower leg. It is desirable to be in the center of the side surface, preferably posterior to the center of the medial side surface of the upper end of the tibia. Further, it is desirable that the end point is at least the center of the inner side surface of the lower end of the tibia, preferably the front side of the center of the inner side surface of the lower end of the tibia, on the half surface when the inner side of the crus is viewed from the side. With such a design, the lower leg can be effectively rotated internally.

(Second leg tightening part 2)
The second crus tightening portion 2 has a belt-like shape, and in the state where the spats 100 are attached, the tibia, the front surface of the calcaneus, the posterior surface of the tibia and the posterior surface of the calcaneus, and the outer side surface of the lower end of the calcaneus. It is formed as follows. Further, the tightening force of the first crus tightening portion 1 is stronger than the tightening force of the second crus tightening portion 2. If the lower leg part turns too much, the X leg may be promoted. Therefore, by arranging the second crus tightening portion, the crus are guided in the external rotation direction with a weaker force than the first crus tightening portion 1. Thereby, it can suppress that a 1st crus tightening part carries out internal rotation of a crus part too much.

  Further, the tightening force of the first crus tightening portion 1 may be made stronger than the second crus tightening portion 2 by making the width of the first crus tightening portion 1 wider than the width of the second crus tightening portion 2. . Specifically, the tightening force per unit area of the first crus tightening portion 1 and the tightening force per unit area of the second crus tightening portion 2 are made the same, and the width of the first crus tightening portion 1 is set to be the second crus. By making it wider than the width of the tightening portion 2, the tightening force of the entire first crus tightening portion 1 can be made stronger than the tightening force of the entire second crus tightening portion 2. In addition to the method of widening the width, the tightening force per unit area may be increased by the type of yarn, the bonding of the fabric, and the like. Alternatively, the tightening force per unit area may be increased after increasing the width. The difference in the tightening force between the first lower leg tightening portion 1 and the second lower leg tightening portion 2 is desirably set as appropriate in accordance with the degree of the O-leg of the individual.

  The first crus tightening portion 1 and the second crus tightening portion 2 intersect at the center portion in the width direction of the crus at the front surface of the tibia and the rib, and the center portion in the width direction of the crus at the rear surface of the tibia and the rib It is desirable to cross at Thereby, the balance of torsion can be balanced and the lower leg can be rotated in a well-balanced manner. The width | variety of the 2nd lower leg elastic band part 2 can be about 1.5 cm-3.0 cm, for example.

(Knee joint tightening part 3)
The knee joint tightening portion 3 is formed so as to surround the patella 23 (see FIG. 13A) with the spats 100 attached. In other words, the knee joint tightening portion 3 is formed so as to surround the periphery of the patella. A first crus tightening portion 1 and a second crus tightening portion 2 are connected to the lower part of the knee joint tightening portion 3. A thin muscle tightening portion 5, a hamstring tightening portion 6, and an inner broad muscle tightening portion 7 are connected to the upper portion of the knee joint tightening portion 3.

  Since the knee joint tightening portion 3 is provided around the knee joint, it is possible to brake the movement of the knee joint (suppress movement). Further, since the first crus tightening portion 1 is connected to the knee joint tightening portion 3, the first crus tightening portion 1 pulls the knee joint tightening portion 3, so that the effect of suppressing the club moment due to the internal rotation of the knee joint is enhanced. be able to. The width of the knee joint tightening portion 3 can be, for example, about 4.0 cm at the top and about 3.0 cm at the bottom.

(Sewing bar tightening section 4, thin bar tightening section 5, and hamstring tightening section 6)
In order to effectively reduce the knee joint sway, it is effective to brake the extra movement of the muscle connected to the knee joint in addition to the method of directly braking the movement and rotation of the knee itself. FIG. 13B is a diagram illustrating leg muscles. In this embodiment, the muscles connected to the knee joint are particularly focused on the hamstrings 53 including the sewing muscle 51, the thin muscle 52, the biceps femoris, and the like, as shown in FIG. The spats 100 are provided with tightening portions so as to support stable movement of these muscles.

  The sewing muscle tightening portion 4 is formed so as to have a tightening force along the muscle direction of the sewing muscle 51 in a state where the spats 100 are mounted. Specifically, the sewing muscle tightening portion 4 is helically disposed around the thigh along the direction of the sewing muscle 51. In other words, the sewing muscle tightening portion 4 is disposed so as to pass from the medial side surface of the femur to the medial side surface of the femur through the front surface of the femur and the rear surface of the femur in order. The width of the sewing muscle tightening portion 4 can be set to, for example, about 3.5 to 5.0 cm. The width of the sewing muscle tightening portion 4 increases from the bottom to the top. As a result, since the sewing muscle tightening portion 4 is stabilized, it is possible to prevent displacement of the sewing muscle tightening portion 4 and each tightening portion connected to the sewing muscle tightening portion 4.

  The thin muscle tightening portion 5 is formed so as to have a tightening force along the muscle direction of the thin muscle 52 in a state in which the spats 100 are worn, the lower end portion is connected to the upper portion of the knee joint tightening portion 3, and the upper end portion Is connected to the sewing muscle tightening portion 4. In other words, the thin muscle tightening portion 5 is arranged on the rear surface of the femur so as to reach the sewing muscle tightening portion 4 from the inner side surface of the upper end of the tibia. The lower end of the thin muscle tightening portion 5 is connected to the upper portion of the knee joint tightening portion 3 by a heel portion 55 which is a muscle group that brakes the rotation of the knee joint inside the knee joint. As a result, the muscle group that brakes the rotation of the knee joint can be supported, so that the knee joint and muscle sway can be braked. The width of the thin muscle tightening portion 5 may be about 2.5 cm, for example.

  The hamstring tightening portion 6 is formed to have a tightening force along the muscle direction of the hamstrings 53 in a state where the spats 100 are attached. Hamstrings are muscles that mainly affect knee joint rotation in addition to knee joint flexion. In other words, the hamstring tightening portion 6 is arranged on the outer side surface of the femur so as to reach the sewing muscle tightening portion 4 so as to draw an arc from the outer side surface of the upper end of the tibia toward the rear surface of the femur. The hamstring tightening portion 6 has a lower end connected to the upper portion of the knee joint tightening portion 3 and an upper end connected to the sewing muscle tightening portion 4. The width of the hamstring tightening portion 6 can be set to, for example, about 4.0 cm.

  By forming the sewing muscle tightening portion 4, the thin muscle tightening portion 5, and the hamstring tightening portion 6, it is possible to support the muscles that support the knee joint, and therefore it is possible to brake the shaking of the knee joint and muscle.

  Note that at least one of the thin muscle tightening portion 5 and the hamstring tightening portion 6 may be provided, and the sewing muscle tightening portion 4 is one of the thin muscle tightening portion 5 and the hamstring tightening portion 6. , Or both.

(Inner broad muscle tightening part 7)
The inner vastus muscle tightening portion 7 is formed so as to have a tightening force in a direction intersecting the running direction of the muscle fibers of the inner vastus muscle 54 with the spats 100 attached. The muscle fiber is a cell constituting the muscle, and the muscle fiber is arranged in a specific direction, and the direction in which the muscle fiber is arranged is called a running direction. Further, the muscle expands and contracts in the running direction of the muscle fiber. The longitudinal direction of the inner vastus muscle tightening portion 7 intersects with the traveling direction of the muscle fibers of the inner vastus muscle, so that the tightening force acts in the direction intersecting the traveling direction of the muscle fibers of the inner vastus muscle. When the muscle is tightened in the direction intersecting the running direction of the muscle fiber, the muscle is stimulated and the muscle output is increased. The inner vastus muscle tightening portion 7 is preferably formed so as to have a tightening force perpendicular to the traveling direction of the muscle fibers of the inner vastus muscle 54 with the spats 100 attached, but the crossing angle is 90 degrees. Not exclusively. The inner vastus muscle tightening portion 7 is formed on the front surface of the thigh in a substantially parallel manner so as to be positioned between the thin muscle tightening portion 5 and the hamstrings tightening portion 6. The vastus muscle tightening portion 7 is connected to the upper portion of the knee joint tightening portion 3. The medial vastus muscle 54 is a muscle that stretches the knee. Since the inside vastus muscle tightening portion can give an appropriate stimulus to the inside vastus muscle, the muscle output is increased and the force for supporting the knee joint can be increased.

  In addition, since thick blood vessels pass through the back of the knee, it is desirable not to provide each tightening portion on the back of the knee in order not to inhibit blood flow by tightening. By not providing a tightening portion on the back of the knee, it is possible to prevent the joint from bending and stretching.

(Effect of Spats 100)
FIG. 5 is a diagram for explaining the effect of wearing the spats 100. 5A shows the force applied to the legs by wearing the spats 100, and FIGS. 5B and 5C show the effects of wearing the spats 100. FIG.

  The spats 100 according to the first embodiment include (1) tightening portions (sewing muscle tightening portion 4, thin muscle tightening portion 5, and hamstring tightening portion 6) that support muscles that support the knee joint, and (2) extend the knee. A tightening portion that stimulates muscles (inner vastus muscle tightening portion 7), (3) a tightening portion that wraps around the knee joint (knee joint tightening portion 3), and (4) suppressing movement of the knee joint in a direction in which pain occurs ( There are provided tightening portions (a first crus tightening portion 1 and a second crus tightening portion 2) that make the knee difficult to spread outward and suppress a club moment.

  The spats 100 pull the crus with the first crus tightening part 1 wider than the second crus tightening part 2 from the inner side of the knee toward the outer heel, and thus the arrows D and E in FIG. In this direction, the crus can be turned inward to suppress the varus moment of the knee joint, and the swaying of the knee can be braked in the direction of arrow C. Thereby, as shown to (b) of FIG. 5, O leg can be suppressed.

  Further, by supporting the muscles with the respective tightening portions along the muscles that support the knee joint, as shown in FIG. 5C, it is possible to make the knee difficult to spread outward, and causes pain and pain in the knee. Can be reduced.

  Due to the above structure, the spats 100 do not generate correct pressure on the knee joint that causes pain or discomfort or unnecessary tightening force on the lower leg. Can be suppressed. That is, the spats 100 can brake the external rotation of the knee without excessive pressure and tightening.

  Further, the main body portion 101 and each tightening portion are formed of the same material and the same color. Therefore, for example, when the spats 100 are formed in black, the appearance is almost the same as the spats or leggings that are usually worn, and it is not noticed that there is a special function in appearance. Therefore, the user can suppress knee shaking and reduce knee pain by simply wearing the spats 100 in the same way as the spats worn everyday, without taking any special appearance or measures. In other words, the user can enjoy traveling and going out without feeling pain or anxiety of knees by relieving pain when climbing up and down the staircase, which is particularly burdensome, with normal clothes.

  Further, since the spats 100 can suppress the outward movement (lateral thrust) of the knee joint, the spats 100 can also be used as a means for supporting the knee in a sports scene or the like.

  Hereinafter, it will be as follows if one Example of this invention is described based on FIGS. In this example, a bi-con (3D measurement) was used to measure the sway of the knee joint, and the presence or absence of the effect of reducing the O leg deformation of the present invention was verified.

  In this example, the bare product, the cylindrical product α covering the knee joint, and normal spats were compared with the spats 100. In the product α, a U-shaped taping knitting for supporting the knee plate to be lifted is applied to a cylindrical main body portion that covers only the knee. The normal spats are spats that do not include the first lower leg tightening portion 1 and other tightening portions.

〔Test method〕
(1) Markers were attached to eight elderly women who were test subjects in a state where each comparative example was worn (a state where no barefoot was worn). FIG. 6 is a diagram for explaining measurement points in the test of the example. FIG. 6A is a rear view showing the measurement location, FIG. 6B is a right side view showing the measurement location, and FIG. 6C is a front view showing the measurement location. As shown in FIG. 6 (a) to FIG. 6 (c), the marker position is the pelvis (upper anterior iliac spine, upper posterior iliac spine) using the plug-in-gait lower body Ai method, Legs (outside the knee joint, on the straight line between the greater trochanter and the superior anterior iliac spine and at a point 1/3 above the greater trochanter and on the outside of the knee joint, on the straight line between the outside of the knee joint and the external fruit) There were a total of 16 places on the foot (external fruit, rib, second metatarsal head). From the above marker positions, the pelvis, right thigh, left thigh, right lower leg, left lower leg, right foot, and left foot are three or more planes, and the Euler angles between the faces are calculated to calculate the internal and external rotation angles of the knee joint. The reaction moment was identified. All motion analyzes were measured at a sampling frequency of 120 Hz.
(2) A 10m walk was conducted for 6 trials under each condition.

〔Test results〕
A test result is demonstrated based on FIGS. FIG. 7A is a graph showing the test result of the internal / external rotation angle of the example, and FIG. 7B is a table showing the test result of the internal / external rotation angle of the example. FIG. 8A is a graph showing the test result of the club moment of the example, and FIG. 8B is a table showing the test result of the club moment of the example. FIG. 9 is a diagram for explaining the internal / external rotation angle.

  The vertical axis | shaft of (a) of FIG. 7 has shown the internal / external rotation angle. The vertical axis of (a) in FIG. 8 indicates the magnitude of the moment. SD (Standard Deviation) in FIGS. 7A and 8A is a standard deviation, and SE (Standard Error) is a standard error.

  The internal / external rotation angle is a rotation angle at which the knee swings inwardly or outwardly, and is closer to an upright state when the numerical value is low. Specifically, for example, the internal / external rotation angle is an angle θ shown in FIG. 9, an intersection line between a surface passing through the heel and extending perpendicularly to the ground and extending in the front direction of the body, and the outer edge of the heel Is an angle formed by a straight line connecting the end of the foot and the end of the foot (the little finger side). As shown in FIG. 9, when the straight line is located inside the body with respect to the intersection line, the angle θ indicates an internal rotation angle, and when the straight line is located outside the body with respect to the intersection line, the angle θ is Indicates the external rotation angle. The internal and external rotation angles shown in FIG. 7 are positive for both the internal and external rotation angles. When the internal rotation angle increases, the X leg is promoted, and when the external rotation angle increases, the O leg is promoted.

  As shown in FIG. 7, when the spats 100 were attached, the internal / external rotation angle was small compared to other comparative examples. This indicates that the wearing of the spats 100 can suppress the rotation of the lower leg, regardless of the inner and outer rotations of the lower leg. In other words, it shows that the spats 100 braked the knee shaking. Considering that the majority of the O-legs are Japanese, it is considered that the internal / external rotation angle was suppressed by the function of braking the lower leg of the spats 100 in the internal rotation direction. In particular, when the average value between the case where the spats 100 were worn and the case where the user was barefoot was compared, the internal / external rotation angle was reduced by about 30%. This indicates that the rotation of the lower leg portion is suppressed by about 30% by wearing the spats 100.

  As shown in FIG. 8, when the spats 100 were attached, the varus moment decreased as compared with other comparative examples. This indicates that the wearing of the spats 100 suppressed the knee from facing outward. Further, when comparing the average value between the case where the spats 100 are worn and the case where the user is barefoot, the club moment is reduced by about 35%. This indicates that the wearing of the spats 100 suppresses the force that spreads the knee outward by about 35%.

  From the above results, it was found that there is a correlation between the varus moment and the internal / external rotation angle, and that the varus moment can be suppressed by braking the rotation.

  Thus, in the present Example, the effect of the spats 100 which suppresses a club moment was recognized. That is, by causing the crus to rotate inward with the spats 100, the club moment can be suppressed, so that it is possible to brake the external rotation of the knee, that is, it is possible to brake the shaking of the knee joint.

[Supplement]
For reference, the appearance of the spats 100 according to the present invention is shown in FIGS. 10 (a) to 10 (e) and FIGS. 11 (a) to 11 (e). FIG. 10A to FIG. 10E are drawings showing the appearance of the spats according to the present invention. 10A is a plan view of the spats 100, FIG. 10B is a front view of the spats 100, and FIG. 10C is a view of the outside (left side) of the spats 100. 10 is a side view, FIG. 10D is a rear view of the spats 100, and FIG. 10E is a bottom view of the spats 100. FIG. FIG. 11A to FIG. 11E are drawing-substituting photographs showing the appearance of the spats 100 according to the present invention. In particular, FIG. 11A is a drawing-substituting photograph showing the plane of the spats, FIG. 11B is a drawing-substituting photograph showing the front of the spats, and FIG. FIG. 11D is a drawing-substituting photograph showing the back (left side) side of the spats, and FIG. 11E is a bottom view of the spats. It is a drawing substitute photograph. The part shown by the dot in (a) of FIG. 11 and (e) of FIG. 11 shows the filling for adjusting the shape of articles | goods. In addition, since the left side surface and the right side surface of the spats 100 are symmetrical, the drawing substitute photograph showing the right side surface is omitted. Further, in FIG. 11, illustration of the tightening portion 102 is omitted.

  The drawing substitute photograph of FIG. 11 shows the main body 101 as black and the tightening portions as gray for easy understanding, but is not limited to the above. The main body 101 and the tightening portions may be the same color or different colors. For example, when each tightening portion is formed by the stitch adjustment and the main body portion 101 and each tightening portion have the same color, there is almost no difference in color between the main body portion 101 and each tightening portion, and it can be distinguished by shading. Specifically, there is a case where the main body portion 101 is dark black and each tightening portion is light black, or each tightening portion is dark black and the main body portion 101 is light black.

  In addition, a questionnaire regarding the effects of wearing the spats 100 having the configuration shown in FIG. 10 was carried out on six women in their 50s and over who usually had very painful knees. As a result of the questionnaire, 4 out of 6 responded that they were able to feel the reduction of knee pain. Specifically, (1) There was no knee pain at all. (2) The material and knee were stable, and I could move without worrying about knee pain. (3) It feels like the whole foot is cramped and feels good. The climbing up and down of the stairs was also smooth. (4) My knee was supported and I could walk without worrying about the pain. Since I had pain when I did not wear it, I was able to get an answer that I felt the effect.

(Embodiment 2)
When the valgus moment that the knee tends to face inward increases, X leg deformation occurs. In the X-leg deformed state, the hip joint 30 is located outside the straight line connecting the knee joint 31 and the ankle joint 32 (see FIG. 4A, not shown). Therefore, weight is applied to the outside of the knee joint 31 and the ankle joint 32, so that a rotational force, that is, a valgus moment, is applied to the knee joint 31 so that the knee is directed inward. Therefore, in order to reduce X leg deformation, it is effective to suppress the valgus moment by rotating the lower leg part outwardly.

  In the present embodiment, a spats 100a that can suppress a valgus moment by rotating the lower leg part outwardly will be described. The spats 100a are different from the spats 100 shown in FIGS. 1 and 2 in that a tightening portion 10a is provided instead of the tightening portion 10, and the other configurations are the same. In other words, the spats 100a are provided with a tightening portion 10a instead of the tightening portion 10 in the spats 100 shown in FIG.

(Tightening part 10a)
FIG. 12 is a front view when only the left leg tightening portion 10a of the spats according to the second embodiment is taken out.

  The tightening portion 10a is provided with a first crus tightening portion 1a and a second crus tightening portion 2a instead of the first crus tightening portion 1 and the second crus tightening portion 2 as compared with the tightening portion 10 shown in FIG. However, other configurations are the same.

(First lower leg tightening portion 1a)
The first crus tightening portion 1a has a belt-like shape and is formed so as to pass from the outer side surface of the upper end of the radius to the tibia, the front surface of the radius, the rear surface of the tibia, and the outer side surface of the lower end of the radius. Thereby, the lower leg is pulled by the first lower leg tightening part from the outer side of the knee to the inner side so that the lower leg part rotates outwardly. Therefore, the valgus moment of the knee joint can be suppressed, and the swaying of the knee can be braked. As a result, it is possible to brake the external rotation of the knee without excessive pressure and tightening.

(Second lower leg tightening portion 2a)
The second crus tightening portion 2a has a band shape, and is formed so as to pass from the inner side surface of the upper end of the tibia to the front surface of the tibia and the ribs, the rear surface of the tibia and the ribs, and the inner side surface of the lower end of the tibia. The tightening force of the first crus tightening portion 1a is stronger than the tightening force of the second crus tightening portion 2a. For this reason, the second crus tightening portion 2a guides the crus in the internal rotation direction with a weaker force than the first crus tightening portion 1a, so that the first crus tightening portion 1a overrotates the crus. Can be suppressed.

  The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope shown in the claims, and embodiments obtained by appropriately combining technical means disclosed in different embodiments. Is also included in the technical scope of the present invention.
