Description

The present invention relates to socks.

Conventionally, socks with functions have been known. For example, Patent Document 1 describes an ankle joint correction sock that is used for people with foot problems and is equipped with a non-stretchable fabric that has a stronger elasticity than the main fabric of the sock body. An ankle joint correction sock is disclosed in which the fabric is set to pull and correct each ankle joint that needs correction for each left and right foot (see FIGS. 5 and 8 of Patent Document 1).

JP 2019-122507 Publication

However, as in the ankle joint correction socks of Patent Document 1, correction by forcibly pulling each ankle joint has a limit to the tensile force that can be applied, and it is necessary to perform corrections that suit each person's symptoms. be. In contrast, the inventor discovered that by using socks to create a band-shaped tactile sensation pressed against a specific part of the sole of the foot, it is possible to naturally shift one's own weight on the sole of the foot appropriately, and to walk. We found that it was possible to run smoothly.

The present invention has been made in view of this knowledge, and provides a sock that allows the wearer to walk and run smoothly while wearing the sock.

(1) One aspect of the present invention for solving the above problems is a sock that extends along the sole surface including the ground contact sole of the toe of a wearer wearing the sock, from the rear end of the heel surface to the center of the heel surface. The vertical line is the shortest line extending through the line to the sole surface of the ring toe that touches the ground, and among the above vertical lines, the part located inside the hindfoot is the hindfoot vertical line, and the part located inside the midfoot is the midfoot vertical line. , and when the part located within the forefoot is defined as the forefoot vertical line, when the wearer takes a standing posture, it comes into contact with the wearer directly or indirectly through the fabric of the sock, A hindfoot vertical line pressing section that produces a band-shaped tactile sensation along the hindfoot vertical line; a metatarsal vertical line pressing section that generates a band-shaped tactile sensation along the metatarsal vertical line; At least the hindfoot vertical line pressing section of the forefoot vertical line pressing section that generates a tactile sensation of being pressed in a band shape along the vertical line, and the ring finger pressing section that generates a tactile sensation of being pressed on the back surface of the ring finger that touches the ground. , a midfoot vertical line pressing section, and a forefoot vertical line pressing section.

The above-mentioned socks include at least the hindfoot vertical line pressing section, the midfoot vertical line pressing section, and the forefoot vertical line pressing section among the hindfoot vertical line pressing section, the midfoot vertical line pressing section, the forefoot vertical line pressing section, and the ring finger pressing section. either of the parts. Therefore, when the wearer wearing these socks assumes a standing posture (stands upright), the hindfoot vertical line pressing section, the midfoot vertical line pressing section, or the front foot vertical line pressing section provided on the sock (hereinafter also referred to as "rear/middle/forefoot vertical line pressing parts"), the rear foot vertical line, midfoot vertical line, or forefoot vertical line on the sole surface of the wearer's toes corresponds to It is possible to produce a band-like tactile sensation on the line (hereinafter also referred to as "rear/middle/forefoot vertical line"). In addition, in a sock that also has a ring finger pressing section, a tactile sensation of the ground contacting back surface of the ring finger being pressed can be produced in response to the ring finger pressing section.

By the way, normally, when a person (healthy person) walks or runs, the center area on which the load such as the person's body weight is applied (hereinafter also referred to as the "load center area") generally follows the following trajectory within the sole of the foot. Draw and move. That is, when a person lands on the heel, the "load center region" advances in a substantially straight line from the rear end of the heel surface, through the center of the heel surface, toward the vicinity of the base of the ring toe and the little ball of the forefoot. Next, as the foot is twisted from the outside to the inside, the "center of load" changes direction inward at the base of the ring toe and the ball of the little foot in the forefoot, and moves towards the ball of the big toe. . Then, near the ball of the foot, it changes direction again and heads forward, passing through the back of the big toe that touches the ground.

However, due to the habits of each person, deformities of toes, ankle joints, knees, hips, spine, etc., and various diseases, it is not possible to move the "center of load" according to the above trajectory, and it is difficult to walk. In many cases, driving is hindered. Furthermore, even healthy people may want to walk or run more smoothly when playing sports.

On the other hand, when the wearer wears the above-mentioned socks, when the wearer walks or runs, " The band-shaped tactile sensations generated on the rear, middle, and front foot vertical lines can smoothly guide the wearer's forward movement (backward movement of the foot on the landing side). By giving a band-shaped tactile sensation to the "rear/middle/forefoot vertical line" on the sole of the foot, the "center of load" will unconsciously rest on the "rear/middle/forefoot vertical line" ("rear/middle/forefoot vertical line"). /Forefoot vertical line''), lower limbs (lower legs, upper legs), lower limbs, abdomen, back, etc., so body movements are performed, so it is important to optimize the motor function of the lower limbs. This is thought to be because it is possible to achieve this goal. In addition, in a sock that also has a ring finger pressing part, the tactile sensation generated when the ground contacting surface of the ring finger is pressed corresponding to the ring finger pressing part can further smoothly guide the wearer to move forward.

Moreover, since the socks are equipped with the rear/middle/forefoot vertical line pressing parts and the ring finger pressing part, they are extremely light and fit the wearer's feet, reducing the burden on the wearer's feet and making it easy to put on and take off. be. For example, even if you put on shoes while wearing socks outdoors, or if you take off your shoes and put on only socks (wearing only socks), line” or a tactile sensation of being pressed on the ring toe. The same applies to the pressing parts of each toe, such as the "heel and ankle line pressing part" and the "little toe pressing part", the "medial malleolus line pressing part", and the "lateral malleolus line pressing part", which will be described later.

In addition, when the sock is provided with a "back foot vertical line pressing section", it is possible to generate a tactile sensation of being pressed in a band-like manner on the rear foot vertical line on the sole surface of the wearer's foot. As a result, during the wearer's walking or running, the "load center part" generally moves on the vertical line of the hind foot, and more specifically, after the heel of the foot that swings forward touches the ground. , contributes to the stability of the wearer's walking and running posture during the period until the body (torso) moves above the feet that are in contact with the ground. (backward movement of the legs) can be guided smoothly. It also contributes to stabilizing the standing posture when the wearer takes a standing posture (standing upright).

On the other hand, when the sock is provided with a "vertical metatarsal line pressing section", it is possible to produce a tactile sensation of being pressed in a band-like manner on the vertical metatarsal line on the sole of the wearer's foot. As a result, during the wearer's walking or running, during the period when the "center of load" moves on the vertical line of the midfoot, more specifically, when the wearer is walking or running, the weight is placed on the opposite foot (for example, the right foot). It contributes to the stability of the wearer's walking and running posture and helps the wearer move forward during the period when the wearer moves his or her left leg (left leg in the air) from back to front under the body (torso). It can be guided smoothly. Also, during this period, it can prevent the tibia from falling inward (to the arch side), and it can also be used as a walking aid for people with X-legs (genu valgum) who tend to have a posture where their tibia falls inwards. be able to.

In addition, when the sock is provided with a "forefoot vertical line pressing section", it is possible to produce a tactile sensation of being pressed in a band-like manner on the forefoot vertical line on the sole of the wearer's foot. As a result, when the wearer walks or runs, the "center of load" generally changes direction inward near the base of the ring finger and the ball of the little foot in the forefoot during the period when it moves along the vertical line of the forefoot. Specifically, during the period of heading towards the ball of the foot and the period of turning forward near the ball of the foot and passing forward from the ball of the foot through the back of the big toe, the heel lifts up and the foot It contributes to the stability of the wearer's walking and running posture during the period from twisting the ball inward to put the weight on the ball of the foot, and then putting the weight on the big toe and kicking the ground backwards. It can guide the wearer's forward movement smoothly. In addition, by optimizing the torsion of the foot, in other words, part of the weight on the ball of the foot and the big toe is distributed over the vertical line of the forefoot, resulting in a state where the weight is excessively placed on the ball of the foot and the inside of the big toe. It can be used to relieve the "center of load" from slipping forward from a state in which the foot is twisted, or, conversely, to prevent the weight from being sufficiently applied to the ball of the foot and the big toe (the foot is not twisted enough). ), the "center of load" moves forward through the index toe or middle toe, thereby relaxing the movement of the foot, and allowing the "center of load" to easily pass forward from the big toe, making it easier to move when walking. It makes it easier to move the body forward appropriately when riding or running.

Furthermore, when the sock is provided with a "ring finger pressing section", it is possible to produce a tactile sensation of being pressed against the ground-contacting back surface of the wearer's ring finger. As a result, when the wearer walks or runs, the "center of load" generally changes direction inward near the base of the ring finger and the ball of the little foot in the forefoot and moves towards the ball of the foot, and During the period when the foot changes direction forward near the ball of the foot and passes forward from the ball of the foot through the ground surface of the big toe, the foot should be twisted inward after lifting the heel. It contributes to the stability of the wearer's walking and running posture during the period from putting weight on the ball of the foot to putting weight on the big toe and kicking the ground backwards, allowing the wearer to move forward. can be guided smoothly. In addition, part of the weight on the ball of the foot and the big toe is also distributed to the sole surface of the ring toe, causing excessive or insufficient weight to be applied to the ball of the foot and the big toe (excessive or insufficient twisting of the foot). ) can be relaxed or strengthened to make it appropriate so that the ``center of load'' can easily move forward from the big toe, making it easier to move the body forward when walking or running. In addition, the ring finger pressing section has the effect of unconsciously relaxing the wearer's body, and when the wearer walks or runs, the forefoot vertical line pressing section, etc., causes the wearer to move forward. It is possible to further bring out the effect of guiding the movement of the vehicle smoothly. In addition, in combination with the "heel-and-ankle line pressing section" described later, the effect of providing stability in the standing posture (upright posture) can be further enhanced.
The "ring finger pressing section" is provided on the sock together with the "back foot vertical line pressing section," the "midfoot vertical line pressing section," or the "forefoot vertical line pressing section." In particular, it is preferable to provide it together with the "forefoot vertical line pressing section". In this case, a part of the weight on the ball of the foot and the big toe can be distributed both to the vertical line of the forefoot and the ground contact surface of the ring toe, resulting in excessive or insufficient weight being applied to the ball of the foot and the big toe (excessive weight). It is possible to make it more appropriate to prevent the foot from twisting (or the foot is insufficiently twisted), and to make it easier for the ``center of load'' to move forward from the big toe, making it easier to move the body forward when walking or running.

In addition, if a sock is provided with multiple of the following: ``back foot vertical line pressing section'', ``midfoot vertical line pressing section'', and ``front foot vertical line pressing section'', forward movement during walking or running can be prevented. can be guided even more smoothly. Furthermore, if all three of the ``hind foot vertical line pressing section'', ``midfoot vertical line pressing section'', and ``front foot vertical line pressing section'' are provided, forward movement during walking or running can be improved. can be guided stably and smoothly. Furthermore, when the wearer assumes a standing posture (stands upright), the standing posture is stabilized. In particular, if all four of the ``hind foot vertical line pressing section'', ``midfoot vertical line pressing section'', ``front foot vertical line pressing section'', and ``ring finger pressing section'' are provided, the forward It is possible to guide the movement particularly stably and smoothly. Furthermore, even when the wearer takes a standing posture (stands upright), the standing posture can be stabilized.

As used herein, the term "sock" refers to a bag-like cloth that covers the foot or foot and lower leg (lower leg, upper leg), and includes socks, stockings (garter stockings, non-garter stockings, etc.), and pantyhose. In addition, socks include foot covers (pump socks) such as shallow foot covers and deep foot covers, anklets, crew socks, knee socks, and socks of various lengths. It also includes five-finger socks with a toe section branched for five fingers, and tabi-shaped socks with a bifurcated toe section. These shoes have the advantage that the position of the toe is clearly defined in the toe area, making it easy to wear them correctly. It is particularly preferable to apply this method to five-toed socks that allow easy movement of the toes.

The "rear/middle/forefoot vertical line pressing part" produces a "band-shaped" tactile sensation of pressure along the "rear/middle/front foot vertical line" when the wearer of the sock takes a standing posture. Any device that is configured to do so is fine. For example, among the fabrics that make up the heel, sole, and toes of a sock, foamed urethane rubber, silicone rubber, etc. are applied and hardened to the parts of the fabric that overlap the rear/middle/forefoot vertical lines on the sole of the foot when worn. Examples include socks with a "middle/forefoot vertical line pressing section" formed thereon. Note that even if the "rear/middle/front foot vertical line pressing part" made of foamed urethane rubber, silicone rubber, etc. is formed on the inner surface of the sock so as to be in direct contact with the sole of the wearer's foot, the fabric that forms the sock can be used on the sole of the wearer's foot. It may be formed on the outer surface of the sock so as to be in indirect contact through the sock, or it may be formed on both. The thickness of the "rear/middle/forefoot vertical line pressing part" made of foamed urethane rubber, silicone rubber, etc. may be set to a thickness that allows the wearer to feel the tactile sensation of being pressed, and is, for example, 0.3 to 2. Examples include those with a diameter of about 0 mm. The same applies to the pressing parts of each toe, such as the "heel and ankle line pressing part" and the "little toe pressing part", the "medial malleolus line pressing part", and the "lateral malleolus line pressing part", which will be described later.

In addition, parts of the fabric that make up the socks are folded over to form the "rear/middle/front foot vertical line pressing area," or the fabric is thicker than the surrounding area to create "rear/middle/front foot vertical line pressing areas." It is also possible to form a line pressing section. The same applies to the "ring finger pressing part", the pressing parts for each toe such as the "heel and ankle line pressing part" and "little toe pressing part", the "medial malleolus line pressing part", and the "lateral malleolus line pressing part", which will be described later. be.

In addition, the "rear/middle/front foot vertical line pressing part" produces a "band-shaped tactile sensation" on the "rear/middle/front foot vertical line" on the sole of the wearer's foot. The "middle/forefoot vertical line pressing part" itself does not have to be in the form of a continuous band. For example, the "rear/middle/front foot vertical line pressing part" can be created by creating basic block patterns such as circles, rectangles, and V-shapes on the fabric that makes up the socks, with dashed lines at intervals smaller than the two-point discrimination threshold on the sole of the foot. By forming a pattern arranged in a shape of urethane foam rubber or the like, a ``band-shaped pressed tactile sensation'' may be generated on the ``rear/middle/forefoot vertical line''. The same applies to the "heel and ankle line pressing section", "medial ankle line pressing section", and "lateral ankle line pressing section" which will be described later.

The "rear/middle/forefoot vertical line pressing part" does not necessarily have a linear pattern when it is not worn by a wearer (in the state of a product to be sold). Socks are often made of stretchable fabric (knitted fabric), and the strength of stretch may vary depending on the region. Therefore, it is preferable that the sock is provided with "rear/middle/forefoot vertical line pressing parts" in a form and arrangement that takes into consideration the deformation of the fabric due to expansion and contraction when the sock is worn.
However, it is sufficient for the "rear/middle/forefoot vertical line pressing parts" to produce a tactile sensation of being pressed along the "rear/middle/forefoot vertical lines," respectively. It is not required that the "rear/middle/front foot vertical line pressing part" is in contact with the "rear/middle/front foot vertical line". That is, the tactile sensation on the sole surface is dull, and the two-point discrimination threshold on the sole surface is approximately 15 mm or more. Therefore, for the "rear/middle/forefoot vertical line", the "rear/middle/forefoot vertical line pressing part" is about the size of the two-point discrimination threshold on the sole surface of the foot (specifically, about 15 mm). Even if the device is worn out of alignment with the ``rear/middle/front foot vertical line,'' you can still get the tactile sensation that the ``rear/middle/front foot vertical line'' is being pressed in a band-like manner.
The same applies to the "heel and ankle line pressing section", "medial ankle line pressing section", and "lateral ankle line pressing section" which will be described later.

If the sock has both a "ring finger pressing part" and a "forefoot vertical line pressing part", they may be provided separately, but the forefoot vertical line pressing part can be extended forward and the ring finger pressing part and the forefoot vertical line pressing part can be separated. The pressing portion may be formed in series. When both the "forefoot vertical line pressing part" and the "midfoot vertical line pressing part" are provided, the forefoot vertical line pressing part and the midfoot vertical line pressing part are preferably formed in series. Furthermore, when both the "midfoot vertical line pressing section" and the "hindfoot vertical line pressing section" are provided, the midfoot vertical line pressing section and the hindfoot vertical line pressing section are preferably formed in series.

(2) The sock according to (1) above, wherein at least the forefoot vertical line pressing portion of the hindfoot vertical line pressing portion, the midfoot vertical line pressing portion, and the forefoot vertical line pressing portion , and the ring finger pressing portion.

This sock includes at least a "forefoot vertical line pressing section" and a "ring finger pressing section." Therefore, in addition to producing a band-shaped tactile sensation of being pressed on the longitudinal line of the forefoot on the sole surface of the wearer's foot, it is also possible to produce a tactile sensation of being pressed on the ground-contacting back surface of the ring finger of the foot. As a result, during the wearer's walking or running, the "center of load" generally changes direction inward near the base of the ring finger or the ball of the little foot during the period when the wearer moves along the vertical line of the forefoot. It contributes to the stability of the wearer's walking and running posture during the period when the ball is heading towards the ball of the foot, changes direction forward near the ball of the foot, and passes forward from the ball of the foot through the back of the big toe. This allows the person to move forward more smoothly. In addition, part of the weight that is applied to the ball of the foot and the big toe is distributed to the vertical line of the forefoot and the ground surface of the ring toe, thereby optimizing the weight from being excessively or insufficiently applied to the ball of the foot and the big toe. The load center area can be easily moved forward from the big toe, making it easier to move the body forward when walking or running.

(3) Or the sock according to (1), in which at least the midfoot vertical line pressing section is selected from among the rear foot vertical line pressing section, the midfoot vertical line pressing section, and the forefoot vertical line pressing section. It is best to wear socks with

This sock includes at least a "vertical metatarsal line pressing section" and can produce a tactile sensation of being pressed in a band-like manner on the vertical metatarsal line on the sole of the wearer's foot. This contributes to stabilizing the wearer's posture and allows the wearer to move forward smoothly during the period when the "center of load" moves on the vertical line of the midfoot while the wearer walks or runs. can lead to. Also, during this period, it can be used to prevent the tibia from falling inward (arch side), and can be used as a walking aid for people with X-legs (genu valgum) who tend to have their tibia falling inward. Also available.

(4) The sock according to any one of (1) to (3) further includes the hindfoot vertical line pressing section, the midfoot vertical line pressing section, the forefoot vertical line pressing section, and the It is preferable that the sock is provided with both ring finger pressing parts.

These socks are equipped with all four parts: "rear/middle/forefoot vertical line pressing parts" and "ring finger pressing part", so they are particularly stable and smooth for the wearer to move forward when walking or running. can lead to. Furthermore, even when the wearer takes a standing posture (stands upright), the standing posture can be stabilized.

(5) Furthermore, the sock according to any one of (1) to (4), wherein the shortest distance between the center of the heel surface and the medial malleolus is formed along the sole surface of the heel and the medial surface of the wearer's foot. The line between the heel and the medial malleolus is defined as the heel-medial malleolus line, and the shortest line connecting the center of the heel surface and the lateral malleolus along the back surface of the heel and the lateral surface of the foot is defined as the heel-lateral malleolus line, when the wearer is in the standing position. When the wearer assumes a posture, it comes into contact with the wearer directly or indirectly through the fabric forming the sock, producing a tactile sensation that is pressed in a band shape along the heel-medial malleolus line within the back surface of the heel. The sock may be provided with a heel-internal malleolus line pressing section that causes the heel to move, and a heel-lateral malleolus line pressing section that generates a band-like tactile sensation of being pressed along the heel-lateral malleolus line in the back surface of the heel.

This sock includes, in addition to the above-mentioned "rear/middle/forefoot vertical line pressing section" or ring finger pressing section, a heel-internal malleolus line pressing section and a heel-lateral malleolus line pressing section. Therefore, when a wearer wearing these socks assumes a standing posture (standing upright), the sole of the wearer's foot is A band-shaped tactile sensation can be generated on the back surface of the heel along the heel-medial malleolus line and the heel-lateral malleolus line. Thereby, the standing posture of the wearer can be further stabilized. The tactile sensation pressed in a strip along the heel-medial malleolus line and heel-lateral malleolus line can unconsciously relax the wearer's body. Then, the tibia and fibula in the lower leg are placed in appropriate positions relative to the body weight and the load applied to the body. Furthermore, the tibia and fibula are in harmony with the femur of the upper leg, and the pelvis is properly positioned. This is thought to be because it also affects muscles such as the hip joint, abdominal muscles, gluteus maximus, psoas major, and back muscles, making it possible to appropriately stabilize the standing posture of the wearer. For example, even if the subject is a healthy person, if the above-mentioned socks are not worn, the subject should stand upright with his or her hands clasped behind the back near the waist, and the subject's clasped hands should be placed behind the back. If someone standing next to them puts their weight on them, the subject usually loses their balance by arching backwards. However, when the same healthy test subject wears the above-mentioned socks (or becomes the wearer), if he stands upright and puts his hands behind his back near his waist, the wearer's folded hands Even with about two adults riding in the car, it is stable enough to maintain an upright position without falling over.

Note that the ``heel-inner malleolus line pressing portion'' and the ``heel-lateral malleolus line pressing portion'' may also be provided in an appropriate pattern on the sock, taking into consideration the deformation of the fabric due to expansion and contraction when worn. For this reason, the "heel medial malleolus line pressing section" or the "heel lateral malleolus line pressing section" forms a curve, or the heel medial malleolus line pressing section and heel lateral malleolus line pressing section form an angle to form a substantially V-shape. There may be cases.

(6) Furthermore, the sock according to (5), when the wearer assumes the standing posture, contacts the wearer directly or indirectly through the fabric forming the sock, A medial malleolus line pressing portion that extends from the heel-medial malleolus line pressing portion for at least 1 cm or more within the medial side of the foot and producing a tactile sensation of being pressed along the heel-medial malleolus line, and a medial malleolus line pressing portion extending from the heel-lateral malleolus line pressing portion to the foot The sock preferably includes a lateral ankle line pressing part that extends at least 1 cm inside the outer surface and produces a tactile sensation of being pressed along the heel-lateral ankle line.

In addition to the aforementioned "rear/middle/forefoot vertical line pressing section" or ring finger pressing section, the heel medial malleolus line pressing section, heel lateral malleolus line pressing section, and medial malleolus line pressing section extending from the heel medial malleolus line pressing section. and a lateral malleolus line pressing section extending from the heel and lateral malleolus line pressing section. That is, the heel medial malleolus line pressing portion and the heel lateral malleolus line pressing portion are extended not only to the sole surface but also to the medial side surface and the lateral surface of the foot. Therefore, when a wearer wearing these socks assumes a standing posture (stands upright), the back of the wearer's heel is In addition to producing a band-shaped tactile sensation of pressure along the heel-medial malleolus line and heel-lateral malleolus line, the inner ankle of the wearer can also feel a sense of pressure in the wearer's foot corresponding to the medial malleolus line pressing portion and the lateral malleolus line pressing portion. A tactile sensation of being pressed along the heel-medial malleolus line and heel-lateral malleolus line can be generated within the lateral surface and within the lateral surface of the foot. Thereby, it is possible to suppress the lateral (left-right) shaking of the back surface of the wearer's heel, thereby further stabilizing the standing posture.

(7) Furthermore, the sock according to any one of (1) to (6), wherein when the wearer assumes the standing posture, the sock is directly attached to the wearer or At least the little toe of the little toe pressing part that is in indirect contact with the fabric and causing a tactile sensation of being pressed against the ground contacting surface of the little toe, and the middle finger pressing part that produces a tactile sensation of being pressed against the ground contacting back surface of the middle toe. It is preferable that the socks include a pressing part.

In addition to the above-mentioned "rear/middle/forefoot vertical line pressing section" or further including a ring finger pressing section and a heel/ankle line pressing section, this sock includes at least a little finger pressing section and a middle finger pressing section. It is equipped with a little finger pressing part. Here, the little finger pressing part and the middle finger pressing part, like the above-mentioned "ring finger pressing part", have the effect of unconsciously relaxing the wearer's body, and when the wearer walks or runs, the forefoot vertical It is possible to further enhance the function of the line pressing part and the like to smoothly guide the wearer's forward movement. In addition, if the aforementioned "heel and ankle line pressing section" is also provided, when the wearer takes a standing posture, the "heel and ankle line pressing section" together with the "heel and ankle line pressing section" It is possible to further bring out the effect of obtaining stability in posture.

Note that out of the little finger pressing part and the middle finger pressing part, only the little finger pressing part, which has a relatively high effect of relaxing the wearer's body, may be provided in the sock, but if both are provided, the effect of relaxing the wearer's body is further increased. It is more preferable to set the height of the wearer's height higher, since this can further bring out the effect of smoothly guiding the wearer's forward movement by the forefoot vertical line pressing portion and the like when the wearer walks or runs.

Furthermore, the sock according to any one of (1) to (7), wherein when the wearer assumes the standing posture, the sock is provided to the wearer directly or through the fabric forming the sock. At least the thumb pressing part is in indirect contact with the thumb pressing part that causes a tactile sensation of being pressed on the ground-contacting back surface of the big toe, and the foreskin pressing part that produces a tactile sensation of being pressed against the ground-contacting back surface of the big toe. It is a good idea to bring socks with you.

In addition to the above-mentioned "rear/middle/forefoot vertical line pressing section" or further including a ring finger pressing section and a heel/ankle line pressing section, this sock includes at least a thumb pressing section and a forefinger pressing section. Equipped with a thumb press part. Here, the thumb pressing section and the third finger pressing section have the effect of unconsciously tensioning the wearer's body, contrary to the aforementioned "ring finger pressing section," little finger pressing section, and middle finger pressing section. Therefore, when training for walking or running, if you wear socks that have this thumb press section or thumb press section and forefinger press section, you can train in a state where the muscles of the lower limbs and other areas are tense, and the effectiveness of the training can be improved. can be increased.

Note that out of the thumb pressing part and the third finger pressing part, the sock may be provided with only the thumb pressing part, which has a relatively high effect of tensing the wearer's body, but if both are provided, the effect of tensing the wearer's body is further increased. This is more preferable because it can improve the effectiveness of training and the like.

(9) Furthermore, the sock according to any one of (1) to (8) may be a five-finger type sock or a tabi-type sock.

Five-finger type socks, where the toe area is divided into each toe, and tabi-type socks, where the toe area is divided into the big toe and the remaining four toes, are replaced with regular socks without the toe area separated. In contrast, it is easy to grip the floor surface with the four toes other than the big toe (the back surface of each toe that touches the ground) on the sole surface of the foot, so the effect of providing a forefoot vertical line pressing section is particularly likely to be produced.

(10) Furthermore, the sock according to any one of (1) to (9) is preferably a sock in which the fabric is a stretchable knitted fabric.

In this sock, since the fabric forming the sock is a stretchable knitted fabric, the above-mentioned "rear/middle/forefoot vertical line pressing section" provided in this sock, or the ring finger pressing section and heel-ankle line pressing section etc., fit the curved surfaces of the sole, medial surface, and lateral surface of the foot, and come into contact with the "rear/middle/forefoot vertical lines" on the sole of the foot, either directly or indirectly through the knitted fabric of the sock. It is possible to reliably produce a tactile sensation of being pressed by the "rear/middle/front foot vertical line pressing section" or the like on the "rear/middle/front foot vertical line" on the sole of the person's foot. Note that as the stretchable knitted fabric, a known knitted fabric such as a plain knitted fabric can be used.

First, the foot HL (specifically, the left foot HLL) of the wearer HM who wears (wears) this sock 10 will be described using FIGS. 2 to 4. FIG. 2 is a diagram of the left foot HLL of the wearer HM viewed from below. FIG. 3 is a perspective view of the left foot HLL of the wearer HM viewed diagonally from above on the outside, and FIG. 4 is a perspective view of the left foot viewed diagonally from below inside.

The foot HL can be roughly divided into five parts: the hindfoot RF, which forms the heel HH, the midfoot MF, which includes the arch MFT, and the forefoot FF, which is in front of the arch MFT (upper in Figure 2). It consists of the toes HF. The five toes HF are the big toe FT, the index toe FI, the middle toe FM, the ring toe FK, and the little toe FP.

Consider the sole surface US, the lateral surface OS, and the medial surface IS of the foot HL (left foot HLL). In addition, the sole surface US includes the ground contact surface corresponding to the pad of each toe HF, that is, the ground contact surface FTS of the big toe FT, the ground contact surface FIS of the third toe FI, the ground contact surface FMS of the middle toe FM, and the ground contact surface of the ring toe FK. It also includes the back FKS and the back FPS of the little toe FP.

Of the sole surface US, the portion belonging to the rear foot RF is defined as the heel sole surface USH, and the central portion thereof is defined as the heel surface center USHC. Further, the rear end portion of the back surface of the heel USH is defined as the rear end of the heel surface USHB. The portion of the sole surface US that belongs to the forefoot FF includes the thenar ball UST of the big toe FT and the little toe ball USP of the little toe FP. Furthermore, the lateral surface OS of the foot includes the lateral malleolus OA that projects outward, and the medial foot surface IS includes the medial malleolus IA that projects inward.

In addition, as shown by the thick broken line in FIG. 2, a straight line extends along the sole surface US of the wearer HM, from the rear end of the heel surface USHB, through the heel surface center USHC, to the ground contact sole surface FKS of the ring toe FK. Assume the shortest line (vertical line VL). Of this vertical line VL, the part included in the hindfoot RF is the hindfoot vertical line RVL, the part included in the midfoot MF is the midfoot vertical line MVL, and the part included in the forefoot FF is the forefoot vertical line. Let it be FVL.

In addition, as shown by thick broken lines in FIGS. 2 to 4, the shortest line (heel-lateral malleolus line KOL). Furthermore, the shortest line (heel-medial malleolus line KIL) connecting between the heel surface center USHC and the medial malleolus IA is assumed along the sole surface US and medial surface IS of the wearer HM.

Now, as mentioned above, when a person (healthy person) walks or runs, the "load center area" which is the central area on which the load such as the person's body weight is applied is generally within the sole surface US, as shown in Figure 2. It moves by drawing a movement trajectory RR indicated by a thick dashed-dotted arrow. In other words, after the foot HL that has swung forward lands on the back surface of the heel USH, the "center of load" passes from the rear end of the heel surface USHB, through the center of the heel surface USHC, to the base of the ring finger FK and the little finger of the forefoot FF. It travels almost in a straight line toward the vicinity of the ball USP. Next, as the foot HL is twisted from the outside to the inside, the "load center area" is shifted inward (towards the upper left in Fig. 2) at the base of the ring toe FK and the little foot ball USP in the forefoot FF. Convert and head towards the thenar ball UST. Thereafter, the ball changes direction again near the ball of the foot UST and heads forward (upward in FIG. 2), passing through the ground contacting back surface FTS of the big toe FT and exiting forward.

However, due to the habits of each person, deformities of toes, ankle joints, knees, hips, spine, etc., and various diseases, it is not possible to move the "load center part" according to the above-mentioned movement trajectory RR. In many cases, it interferes with walking and running. Furthermore, even healthy people may want to walk or run more smoothly when playing sports.

Therefore, as the sock 10 of the first embodiment, a five-finger sock shown in FIG. 1 is used. This sock 10 is a known five-finger sock made of stretchable knitted fabric 1N, with a vertical line pressing section 3 and a heel-ankle line pressing section 4 provided on the surface. That is, the sock 10 includes a leg part 1L surrounding the part above the ankle of the foot HL of the wearer HM, a heel part 1H covering the heel part HH of the foot HL including the sole surface USH of the sole surface US, and a sole surface US. In addition to the bottom part 1B that covers the parts included in the middle foot part MF and the forefoot part FF, it has a bag-shaped thumb part 1T in which each toe HF is placed, an index toe part 1I, a middle finger part 1M, a ring finger part 1K, and a little finger part 1P. ing. Due to the elasticity of the 1N fabric, when this sock 10 is worn on the foot HL of the wearer HM, it fits the curved surfaces of the foot HL, such as the sole surface US, the medial surface IS, and the lateral surface OS. ing.

On the other hand, the vertical line pressing part 3 and the heel-ankle line pressing part 4 are made of foamed urethane rubber, are formed by a known screen printing method, and have a thickness within the range of 0.3 to 2.0 mm. The thickness is 0.7 mm. A large number of V-shaped basic patterns form a band-like pattern arranged in broken lines at predetermined intervals smaller than the two-point discrimination threshold of the sole surface US. More specifically, the vertical line pressing part 3 has a V-shaped basic pattern with the pointed end side facing forward, with a gap equal to or less than the thickness of this basic pattern, specifically 2 mm. A large number of them are lined up at intervals of , forming a band shape. In addition, the heel and ankle line pressing parts 4 are arranged in a strip shape in large numbers with the pointed end side of the V-shape facing the center part of the heel and ankle line pressing part 4 with a gap of about the same size or less as the thickness of the basic pattern. It has a similar shape.

5 to 7 show the state in which the sock 10 shown in FIG. 1 is worn (weared) on the foot HL (left foot HLL) of the wearer HM. As can be understood from FIGS. 5 to 7, the vertical line pressing portion 3 overlaps the vertical line VL when the sock 10 is attached (weared) to the foot HL of the wearer HM. That is, in a state where the sock 10 is attached to the foot HL of the wearer HM, the vertical line pressing portion 3 presses the heel portion 1H, bottom portion 1B, and ring finger portion 1K of the sock 10 so as to overlap the vertical line VL. is formed.

In addition, of the vertical line pressing part 3, the part included in the hindfoot part RF and overlapping with the hindfoot vertical line RVL is referred to as the hindfoot vertical line pressing part 3A, and the part included in the midfoot part MF and overlapping with the midfoot vertical line MVL. is the midfoot vertical line pressing part 3B, the part included in the forefoot FF and overlapping with the forefoot vertical line FVL is the forefoot vertical line pressing part 3C, and the part included in the ground contacting back surface FKS of the ring finger FK is the ring finger pressing part 3D. (See Figures 1 and 5).

As described above, since the vertical line pressing part 3 is formed to have a thickness of 0.7 mm, the wearer HM wearing the sock 10 on which the vertical line pressing part 3 is formed has a On the back side US, there is a vertical line VL (hind foot vertical line RVL) where the vertical line pressing parts 3 (hind foot vertical line pressing part 3A, middle foot vertical line pressing part 3B, forefoot vertical line pressing part 3C, ring finger pressing part 3D) overlap. , the midfoot vertical line MVL, the forefoot vertical line FVL, and the ground contact surface FKS of the ring toe FK), a band-shaped tactile sensation is generated. That is, a rear foot vertical line pressing section 3A, a middle foot vertical line pressing section 3B, and a forefoot vertical line pressing section 3C (hereinafter referred to as "rear/middle/front foot vertical line pressing section" 3A) constitute the vertical line pressing section 3. , 3B, and 3C) are the rear foot vertical line RVL, middle foot vertical line MVL, and forefoot vertical line FVL (hereinafter, these are referred to as the "rear/middle/front foot vertical line") of the vertical lines VL. (Also written as ``RVL, MVL, FVL.'') produces a tactile sensation that is pressed in a band-like manner. Further, the ring finger pressing portion 3D produces a tactile sensation of being pressed against the ground contacting back surface FKS of the ring finger FK.

Further, as can be understood from FIGS. 5 to 7, when the sock 10 is attached (weared) to the foot HL of the wearer HM, the heel-to-inner malleolus line presser 4 is pressed against the heel-medial malleolus line KIL and the heel-lateral malleolus line KOL. overlaps with That is, in a state where the sock 10 is attached (weared) on the foot HL of the wearer HM, the heel-ankle line pressing part 4 presses the heel of the sock 10 so that it overlaps the heel-inner ankle line KIL and the heel-lateral ankle line KOL. It is formed in part 1H.

Specifically, the heel-internal malleolus line pressing section 4A of the heel-internal malleolus line pressing section 4 overlaps a portion of the heel-internal malleolus line KIL located within the sole surface US (within the heel sole surface USH). Furthermore, the medial malleolus line pressing portion 4C extends from the heel-medial malleolus line pressing portion 4A into the medial side surface IS of the foot, and overlaps the portion of the heel-medial malleolus line KIL located within the medial foot surface IS. However, in the sock 10 of Embodiment 1, the length 4CL of the medial ankle line pressing portion 4C is set to be 1 cm or more, specifically 2 cm (see FIG. 7).

On the other hand, the heel-lateral malleolus line pressing section 4B of the heel-lateral malleolus line pressing section 4 overlaps a portion of the heel-lateral malleolus line KOL located within the sole surface US (within the heel sole surface USH). Furthermore, the lateral malleolus line pressing section 4D extends from the heel-lateral malleolus line pressing section 4B into the lateral surface OS of the foot, and overlaps with the portion of the heel-lateral malleolus line KOL located within the lateral surface OS of the foot. However, in the sock 10 of the first embodiment, the length 4DL of the lateral ankle line pressing portion 4D is also set to be 1 cm or more, specifically 2 cm (see FIG. 6).

As mentioned above, since the heel and ankle line pressing portion 4 is also formed to have a thickness of 0.7 mm, the wearer HM wearing the socks 10 on which this heel and ankle line pressing portion 4 is formed A band-shaped tactile sensation is generated along the heel-internal malleolus line KIL and the heel-lateral malleolus line KOL, where the heel-internal malleolus line pressing portion 4A and heel-lateral malleolus line pressing portion 4B overlap on the back surface of the heel USH. In addition, a band-shaped tactile sensation is generated along the heel-medial malleolus line KIL where the medial malleolus line pressing portion 4C in the medial foot surface IS overlaps. Similarly, a band-shaped tactile sensation is generated along the heel-lateral malleolus line KOL where the lateral malleolus line pressing portion 4D in the lateral surface OS of the foot overlaps. In other words, the heel-internal malleolus line pressing section 4A and the heel-lateral malleolus line pressing section 4B respectively apply band-like force to the wearer HM wearing the sock 10 along the heel-medial malleolus line KIL and heel-lateral malleolus line KOL within the back surface of the heel USH. Produces a tactile sensation of being pressed. In addition, the medial malleolus line pressing portion 4C causes the wearer HM wearing the sock 10 to feel a tactile sensation of being pressed in a band shape along the heel-medial malleolus line KIL within the medial side surface IS of the foot, and the lateral malleolus line pressing portion 4D produces a band-shaped tactile sensation that is pressed along the heel-lateral malleolus line KOL within the lateral surface OS of the foot.

In addition, since the sock 10 is made of a stretchable knitted fabric 1N, the vertical line pressing portion 3 and the heel-ankle line pressing portion when the sock 10 is worn on the foot HL (FIGS. 5 to 7) 4 is different from the form of the vertical line pressing part 3 and the heel-ankle line pressing part 4 in the sock 10 (see FIG. 1) in the undressed state (in the state of a product to be sold). The form and arrangement of the vertical line pressing part 3 and the heel-to-ankle line pressing part 4 formed on the sock 10 are preferably formed in consideration of the elasticity of the sock 10 and the form of the sock 10 when it is attached (wearing) to the foot HL. For example, In the sock 10 of Embodiment 1, as shown by the thick broken line in FIG. 1, of the heel and ankle line pressing parts 4, the heel medial malleolus line pressing part 4A and the heel lateral malleolus line pressing part 4B are not linear, It is formed at an angle θ.

The same applies to the vertical line pressing portion 3, and in consideration of the deformation of the fabric due to expansion and contraction when worn, the sock 10 is provided with “rear/middle/forefoot vertical line pressing portions” 3A, 3B, in an appropriate form and arrangement. It is good to provide 3C.

Now, as shown in FIGS. 5 to 7, when the wearer HM wears the sock 10 in which the vertical line pressing part 3 and the heel-ankle line pressing part 4 are formed, the following effects occur. First, to explain the action of the vertical line pressing section 3, when the wearer HM walks or runs, corresponding to the "rear/middle/forefoot vertical line pressing section" 3A, 3B, 3C provided on the sock 10, The band-shaped tactile sensations generated on the "rear/middle/forefoot vertical lines" RVL, MVL, and FVL can smoothly guide the wearer's HM forward movement. That is, it is possible to smoothly guide the backward movement of the foot HL on the landing side.

The mechanism by which this effect occurs is not clear, but by giving a band-like tactile sensation to the "rear/middle/front foot vertical lines" RVL, MVL, and FVL on the sole of the foot, the "rear/middle/front foot vertical lines" are unconsciously created. The wearer HM moves so that the "load center part" is placed on the "rear/middle/forefoot vertical lines" RVL, MVL, FVL, so that the load such as the wearer's weight is applied to the Movements of the lower extremities (lower legs, upper legs), lower back, abdomen, and back are performed. Therefore, it is considered that the motor function of the lower limbs of the wearer HM can be optimized.

Note that the sock 10 of the first embodiment also includes a ring finger pressing portion 3D. Therefore, the tactile sensation generated when the ground contacting back surface FKS of the ring finger FK is pressed corresponding to the ring finger pressing portion 3D can further smoothly guide the wearer HM to move forward. The respective functions of the "rear/middle/forefoot vertical line pressing parts" 3A, 3B, and 3C provided on the sock 10 will be described later.

Next, the action of the heel and ankle line pressing section 4 will be explained. First, the functions of the heel-internal malleolus line pressing section 4A and the heel-lateral malleolus line pressing section 4B will be explained. When the wearer HM wearing the sock 10 assumes a standing posture (stands upright), the wearer HM's A band-shaped tactile sensation can be generated in the back surface of the heel USH along the heel-internal malleolus line KIL and the heel-lateral malleolus line KOL. Thereby, the standing posture of the wearer HM can be further stabilized.

Although the mechanism by which this effect occurs is not clear, by providing a band-like tactile sensation that is pressed along the heel-internal malleolus line KIL and heel-lateral malleolus line KOL within the back surface of the heel USH, the wearer's body unconsciously relaxes. You can do it. Then, the tibia and fibula in the lower leg are placed in appropriate positions relative to the body weight and the load applied to the body. Furthermore, the tibia and fibula are in harmony with the femur of the upper leg, and the pelvis is properly positioned. Furthermore, it is thought to have an effect on muscles such as the hip joint, abdominal muscles, gluteus maximus, psoas major, and back muscles, thereby appropriately stabilizing the wearer's standing posture. For example, even if the subject is a healthy person, if the subject is not wearing the socks 10 of Embodiment 1 and is barefoot or wearing regular five-toe socks, the subject should stand upright and place his or her hands behind his or her back near the waist. If someone standing behind the subject puts their weight on the subject's folded hands while the subject is in a crossed posture, the subject will arch backwards and lose balance, as shown in the photograph in Figure 8. However, when the same healthy subject wears the socks 10 (wearer HM), if he stands upright and puts his hands behind his back near his waist, the result will be as shown in Fig. 9. Even if two adults sit on the folded hands of the wearer HM, the standing posture (upright posture) is stable enough to prevent the wearer from falling over.

In particular, in the sock 10 of the first embodiment, in addition to the heel-internal malleolus line pressing section 4A and the heel-lateral malleolus line pressing section 4B, it also has a medial malleolus line pressing section 4C and a lateral malleolus line pressing section 4D extending therefrom. There is. Therefore, when the wearer HM wearing the sock 10 assumes a standing posture (stands upright), the inner surface of the wearer's foot is A tactile sensation that is pressed along the heel-medial malleolus line KIL and heel-lateral malleolus line KOL (a tactile sensation that is pressed so as to sandwich the heel HH of the foot HL) can be generated in the IS and the lateral surface OS of the foot. . Thereby, it is possible to suppress the lateral (left-right) shaking of the back surface USH of the heel of the wearer HM, thereby further stabilizing the standing posture.

Moreover, since the sock 10 is a known five-finger sock with a vertical line pressing section 3 and a heel-to-ankle line pressing section 4, it is very light and fits the foot HL of the wearer HM, making it easy for the wearer to wear it. There is less burden on the foot HL of the HM, and it is easy to put on and take off. In addition, even if you wear socks 10 and shoes (not shown), or if you wear only socks 10 indoors, the vertical line pressing section 3 and heel-ankle line pressing section 4 can handle the situation. A tactile sensation of being pressed can be produced in the area to be pressed.

(Examples 1 to 15, Comparative Example 1, Reference Examples 1 and 2)
Next, using a known five-finger sock similar to that used in the sock 10, "rear/middle/forefoot vertical line pressing parts" 3A, 3B, 3C, ring finger pressing part 3D, heel-internal malleolus line pressing part 4A, etc. Regarding the socks of Examples 1 to 15, Comparative Example 1, and Reference Examples 1 and 2, in which the little finger pressing part 5P etc. were provided in various patterns, "smoothness of walking and running" was achieved, that is, the forward movement of the wearer HM. The ability to guide the movement smoothly was evaluated on a five-point scale (A to E, with A being the best). In addition, the "stability of standing posture" is determined, that is, whether the standing posture can be maintained even when the body is rocked back and forth and from side to side when standing upright with feet approximately shoulder-width apart (standing posture). The stability was similarly evaluated on a 5-grade scale (A to E, with A being the best). Table 1 shows the configuration and results of each pressing part in each example. In addition, in "stability of standing posture", the stability shown in FIG. 9 corresponds to B rating.

Note that the sock 10 of Embodiment 1 described above (see FIG. 1) corresponds to the sock of Example 11 in Table 1. Further, the "inner heel/lateral ankle line pressing section" column in Table 1 indicates the presence or absence of the inner heel/lateral ankle line pressing section 4A and the heel/lateral ankle line pressing section 4B. In addition, the "medial/lateral malleolus line pressing section" column indicates the presence or absence of the medial malleolus line pressing section 4C and the lateral malleolus line pressing section 4D, and the numerical value (2 cm) indicates the lengths 4CL and 4DL of these (Figs. 6 and 7 (see).

<Variation 1, Example 13>
The "little toe pressing part" in Table 1 produces a tactile sensation of being pressed against the ground contact surface FPS of the little toe FP when the wearer HM assumes a standing posture. Specifically, for example, as shown in FIG. In the sock 10A of Modified Embodiment 1 shown in FIG. 1, a little finger pressing portion 5P is formed on the little finger portion 1P. Furthermore, the "middle finger pressing part" in Table 1 produces a tactile sensation of being pressed against the ground contact surface FMS of the middle toe FM when the wearer HM assumes a standing posture. In the sock 10A of modification 1 shown in No. 10, a middle finger pressing portion 5M is formed on the middle finger portion 1M. That is, the sock 10A of the first modification is the sock 10 of the first embodiment further provided with a little finger pressing section 5P and a middle finger pressing section 5M, and corresponds to the thirteenth embodiment.

<Variation 2, Example 15>
The "thumb pressing part" in Table 1 produces a tactile sensation of being pressed against the ground contact surface FTS of the big toe FT when the wearer HM assumes a standing posture. Specifically, for example, as shown in FIG. In the sock 10B of Modified Embodiment 2 shown in FIG. 1, a thumb pressing portion 5T is formed on the thumb portion 1T. In addition, the "forefinger pressing part" in Table 1 produces a tactile sensation of being pressed against the ground contacting back surface FIS of the forefinger FI when the wearer HM assumes a standing posture. In the sock 10B of the second modification shown in No. 11, the forefinger pressing portion 5I is formed on the forefinger portion 1I. That is, the sock 10B of the second modification is the sock 10 of the first embodiment further provided with a thumb pressing portion 5T and a third finger pressing portion 5I, and corresponds to the fifteenth embodiment.

<Variation 3, Example 8>
In addition, as shown in FIG. 12, the sock 10C may be provided with only the middle foot vertical line pressing section 13B among the "rear/middle/front foot vertical line pressing sections". Note that since no rear foot vertical line pressing section is provided, unlike the heel and ankle line pressing section 4 of Embodiment 1 and the like, the heel and ankle line pressing section 14 has a pattern formed up to the central portion. This sock 10C of modification 3 corresponds to Example 8 in Table 1.

(Evaluation of each example)
Examples 1 to 15, Comparative Example 1, and Reference Examples 1 and 2 will be discussed. Comparative Example 1 is simply a known five-finger sock. Therefore, the socks of Comparative Example 1 were used as standards for "smoothness of walking and running" and "stability of standing posture", and both evaluations were given as E.

Example 1 is a sock in which the sock of Comparative Example 1 is provided with only the rear leg vertical line pressing portion 3A. The sock equipped with the hindfoot vertical line pressing portion 3A can produce a tactile sensation of being pressed in a band-like manner on the hindfoot vertical line RVL on the sole surface US of the wearer HM (see also FIGS. 1 to 7). As a result, during the wearer HM's walking or running, during the period when the "load center region" moves on the hindfoot vertical line RVL, specifically, the heel HH of the foot HL that swings forward is It contributes to the stability of the wearer's HM's walking and running postures during the period after the body (torso) moves above the grounded feet HL, and it helps the wearer's HM to move forward. Movement (backward movement of the foot HL on the landing side) can be guided smoothly. It also contributes to stabilizing the standing posture when the wearer HM takes a standing posture. Therefore, the "smoothness of walking and running" was given a D rating, which was slightly better than Comparative Example 1. Furthermore, the "stability of standing posture" was also rated D.

Example 2 is a sock in which only the midfoot vertical line pressing portion 3B is provided in the sock of Comparative Example 1. When the sock is provided with the midfoot vertical line pressing part 3B, it is possible to generate a tactile sensation of being pressed in a band shape on the midfoot vertical line MVL on the sole surface US of the wearer HM (Figs. 1 to 7, Fig. 12 (see also). As a result, while the wearer HM is walking or running, during the period in which the "load center region" moves on the midfoot vertical line MVL, more specifically, the "load center region" generally moves on the opposite foot HL (e.g., When the weight is on the right leg, the left leg (left leg lifted) is moved from back to front under the body (torso), contributing to the stability of the wearer's walking and running postures, and We can help you move smoothly. However, unlike Example 1, even if the midfoot vertical line pressing portion 3B is provided, it hardly contributes to the stability of the standing posture when the wearer HM takes a standing posture. Therefore, the "smoothness of walking and running" was given a D rating, which was slightly better than Comparative Example 1. On the other hand, "stability of standing posture" was rated E.
In addition, the socks of Example 2 can also reduce the tendency of the tibia of the lower leg to fall inward (towards the arch of the foot) during the period when the "load center region" moves on the midfoot vertical line MVL. For this reason, as described in the notes section, it can also be used to assist people with walking legs (genu valgum), who tend to have their tibia in a posture that falls inwards.

Example 3 is a sock in which the sock of Comparative Example 1 is provided with only the forefoot vertical line pressing portion 3C. When the sock is provided with the forefoot vertical line pressing section 3C, it is possible to generate a band-like tactile sensation of being pressed against the forefoot vertical line FVL on the sole surface US of the wearer HM (see also FIGS. 1 to 7). As a result, when the wearer HM walks or runs, the "center of load" generally moves on the forefoot vertical line FVL, while the forefoot FF is in the vicinity of the base of the ring finger FK and the little ball USP. Specifically, during the period in which the ball changes direction and heads toward the thenar ball UST, and the period in which it changes direction forward near the thenar ball UST and passes forward from the thenar ball UST through the ground contact surface FTS of the big toe FT. During this period, the heel HH lifts up, the foot HL is twisted inward and weight is applied to the ball of the foot UST, and then the weight is applied to the big toe FT to kick the ground backwards. , contributes to stabilizing the walking posture and running posture of the wearer HM, and can smoothly guide the forward movement of the wearer HM. In addition, by optimizing the torsion of the foot HL, in other words, part of the weight applied to the ball of the foot UST and big toe FT is distributed to the forefoot vertical line FVL, and excessive or insufficient weight is distributed to the ball of the foot UST and big toe FT. (excessive or insufficient twisting of the foot HL), and allow the "center of load" to easily pass forward from the big toe FT, allowing the body to move forward appropriately when walking or running. can be easily done. However, unlike Example 1, even if the forefoot vertical line pressing portion 3C is provided, it hardly contributes to the stability of the standing posture when the wearer HM takes a standing posture. Therefore, the "smoothness of walking and running" was given a D rating, which was slightly better than Comparative Example 1. On the other hand, "stability of standing posture" was rated E.

Example 4 is a sock in which a ring finger pressing part 3D is further provided in addition to the sock of Example 3 in which only the forefoot vertical line pressing part 3C is provided. When the sock is provided with the ring finger pressing portion 3D, it is possible to generate a tactile sensation of being pressed against the ground contacting back surface FKS of the ring finger FK of the wearer HM (see also FIGS. 1 to 7). As a result, when the wearer HM walks or runs, the "center of load" generally changes direction inward at the base of the ring finger FK of the forefoot FF and near the little ball USP, and heads toward the thenar ball UST. Specifically, the heel HH was generally lifted during the period and during the period when the direction was changed forward near the thenar UST and the foot passed forward from the thenar UST through the ground contact surface FTS of the big toe FT. After that, the wearer HM's walking posture and running change during the period from twisting the foot HL inward and putting weight on the ball of the foot UST, and then putting weight on the big toe FT and kicking the ground backwards. It contributes to postural stability and allows the wearer to move forward smoothly. In addition, a part of the weight applied to the thenar ball UST and the big toe FT is also distributed to the ground contact surface FKS of the ring toe FK, and the weight is applied excessively or insufficiently to the thenar ball UST and the big toe FT (excessively or insufficiently). By sufficiently relaxing or strengthening the twisting of the foot (HL), the "center of load" can easily move forward from the big toe (FT), allowing the body to move forward appropriately when walking or running. can be easily done. In addition, the ring finger pressing section 3D has the effect of unconsciously relaxing the wearer's body, and when the wearer HM walks or runs, the forefoot vertical line pressing section 3C etc. causes the wearer's HM to relax. It is possible to further bring out the effect of smoothly guiding forward movement. However, even if the forefoot vertical line pressing section 3C and the ring finger pressing section 3D are provided, they hardly contribute to the stability of the standing posture when the wearer HM takes a standing posture. Therefore, the "smoothness of walking and running" was given a C rating, which was better than that of Example 3. On the other hand, "stability of standing posture" was rated E. Although not obtained in this Example 4, when the heel-internal malleolus line pressing part 4A and the heel-lateral malleolar line pressing part 4B are also provided, as in Examples 10 to 15 described later, in conjunction with these, , it is possible to further bring out the effect of obtaining stability in the standing posture (upright posture).

Example 5 is a sock in which the sock of Comparative Example 1 is provided with three "rear/middle/forefoot vertical line pressing parts" 3A, 3B, and 3C (see also FIGS. 1 to 7). In the sock of Example 5, the effects of the above-mentioned "rear/middle/forefoot vertical line pressing portions" 3A, 3B, and 3C can be obtained. This contributes to stabilizing the walking and running postures of the wearer HM during the entire period of walking and running, and allows the wearer HM to move forward (behind the foot HL on the landing side). movement) can be guided smoothly. Further, the rear leg vertical line pressing portion 3A can also contribute to stabilizing the standing posture when the wearer HM takes a standing posture (stands upright). Therefore, the "smoothness of walking and running" was evaluated as C, which was better than Examples 1 to 3. Furthermore, the "stability of standing posture" was also rated D.

Example 6 is a sock in which a ring finger pressing portion 3D is further provided in addition to the sock of Example 5 (see also FIGS. 1 to 7). Therefore, in addition to obtaining the same effect as the socks of Example 5, the "smoothness of walking and running" was evaluated as B, which was better than that of Example 5, similar to Example 4 for Example 3. On the other hand, regarding the "stability of standing posture", it was evaluated as D, which is the same as in Example 5.

In Example 7, in addition to the sock of Example 1 in which the rear foot vertical line pressing part 3A was provided, only the heel medial malleolus line pressing part 4A and the heel lateral malleolus line pressing part 4B of the heel and ankle line pressing part 4 were provided. These are socks (see also Figures 1 to 7). Therefore, in addition to obtaining the same effect as the sock of Example 1, when the wearer HM wearing this sock assumes a standing posture, the heel medial malleolus line pressing portion 4A provided on the sock and the heel lateral malleolus line press part 4A provided on the sock Corresponding to the line pressing portion 4B, a band-like pressed tactile sensation is generated within the heel surface USH of the sole surface US of the wearer HM along the heel-internal malleolus line KIL and the heel-lateral malleolus line KOL. Thereby, the standing posture of the wearer HM can be further stabilized. Therefore, the "smoothness of walking and running" was rated D, which is the same as in Example 1, but the "stability of standing posture" was rated B, which is two steps better than in Example 1. As mentioned above, this B evaluation is the stability of the standing posture that allows the state shown in FIG. 9 to be obtained.

Example 8 is a sock corresponding to the above-mentioned modification 3 (see FIG. 12), and is an example in which only the midfoot vertical line pressing section 3B (corresponding to the midfoot vertical line pressing section 13B in Example 8) is provided. 2, the sock is further provided with not only the heel-internal malleolus line pressing section 14A and the heel-lateral malleolus line pressing section 14B, but also the medial malleolus line pressing section 14C and the lateral malleolus line pressing section 14D. (See also Figures 1 to 7). Therefore, similar to the effect of the socks of Example 2, during the wearer HM's walking or running, the walking posture of the wearer HM and the It contributes to stabilizing the running posture and allows the wearer to move forward smoothly. Note that the lengths of the medial ankle line pressing section 14C and the lateral ankle line pressing section 14D were each 2 cm. Therefore, when the wearer HM wearing these socks assumes a standing posture, the medial malleolus line pressing portion 14C and the lateral malleolus line pressing portion 14D are applied to the inside and outside of the foot IS of the wearer HM. A tactile sensation of being pressed along the heel-internal malleolus line KIL and the heel-lateral malleolus line KOL can be generated within the side OS. Thereby, it is possible to suppress the lateral (left-right) shaking of the back surface USH of the heel of the wearer HM, thereby further stabilizing the standing posture. Therefore, the "smoothness of walking and running" was evaluated as D, which is the same as in Example 2, but the "stability of standing posture" was evaluated as C, which is better than in Example 2. Additionally, as stated in the notes section, it can also be used to assist people with walking with X-legs (genu valgum), who tend to have their tibias tilted inwards.

Example 9 has the sock of Example 4 which is provided with a forefoot vertical line pressing section 3C and a ring finger pressing section 3D, and further includes a heel medial malleolus line pressing section 4A and a heel lateral malleolus line pressing section 4B of the heel and ankle line pressing section 4. (See also Figures 1 to 7). Therefore, in addition to providing the same effect as the sock of Example 4, the standing posture of the wearer HM can be further stabilized compared to the sock of Example 4. Therefore, the "smoothness of walking and running" was evaluated as C, which is the same as in Example 1, but the "stability of standing posture" was evaluated as C, which was two steps better than in Example 4.

Example 10 is the sock of Example 6 which is provided with the three "rear/middle/forefoot vertical line pressing parts" 3A, 3B, 3C and the ring finger pressing part 3D, and further includes: This sock is provided with only a heel-internal malleolus line pressing portion 4A and a heel-lateral malleolus line pressing portion 4B (see also FIGS. 1 to 7). Therefore, in addition to obtaining the same effect as the sock of Example 6, it is possible to generate a band-shaped tactile sensation that is pressed along the heel-internal malleolus line KIL and the heel-lateral malleolus line KOL in the back surface of the heel USH. can. Thereby, the standing posture of the wearer HM can be further stabilized. Therefore, the same B rating as in Example 6 was obtained for "smoothness of walking and running." Regarding the "stability of standing posture", it was also evaluated as B, which is two steps better than in Example 6.

Example 11 is a sock corresponding to Embodiment 1 (see FIGS. 1 to 7), which is the sock of Example 10, and further includes a medial malleolus line pressing portion 4C and a lateral malleolus line pressing portion of the heel and ankle line pressing portion 4. These socks are provided with a section 4D. The socks of Example 11 (Embodiment 1) had the same effect as the socks of Example 10, and the same B rating as Example 10 was obtained for "smoothness of walking and running." Regarding the "stability of standing posture", the evaluation was A, which was better than that of Example 10. This is because the medial ankle line pressing section 4C and the lateral ankle line pressing section 4D were able to suppress the lateral (left-right) sway on the back surface of the heel USH of the wearer HM, thereby further stabilizing the standing posture.

Example 12 is a sock in which a little finger pressing part 5P is further provided in the little finger part 1P of the sock of Example 11 (Embodiment 1) (see also FIG. 10 in addition to FIGS. 1 to 7). Further, Example 13 is a sock corresponding to Modified Embodiment 1 (see FIG. 10), and is a sock in which a middle finger pressing portion 5M is further provided in the middle finger portion 1M of the sock of Example 12. Therefore, these can provide the same effect as the socks of Example 11. In addition, the little finger pressing section 5P and the middle finger pressing section 5M have the effect of unconsciously relaxing the body of the wearer HM, similar to the ring finger pressing section 3D. Therefore, when the wearer HM walks or runs, it is possible to further bring out the effect of the forefoot vertical line pressing portion 3C and the like to smoothly guide forward movement of the wearer HM when walking or running. Moreover, the stability of the standing posture, which is obtained by providing the heel-and-ankle line pressing part 4, can be further improved. Therefore, the socks of Examples 12 and 13 received the highest A rating in both "smoothness of walking and running" and "stability of standing posture."
Note that, as in Example 12, the sock may be provided with only the little finger pressing part 5P, which has a higher effect of relaxing the body than the middle finger pressing part 5M, but in Example 13 (Modification 1, FIG. 10) By providing both the little finger pressing part 5P and the middle finger pressing part 5M, the effect of relaxing the body of the wearer HM is further enhanced, and when the wearer walks or runs, the forefoot vertical line pressing part 3C, etc. This is more preferable because it can reliably bring out the effect of smoothly guiding the forward movement of the wearer HM.

Example 14 is a sock in which a thumb pressing portion 5T is further provided in the thumb portion 1T of the sock of Example 11 (Embodiment 1) (see also FIG. 11 in addition to FIGS. 1 to 7). Further, Example 15 is a sock corresponding to Modified Embodiment 2 (see FIG. 11), and is a sock in which a forefinger pressing portion 5I is further provided in the forefinger portion 1I of the sock of Example 14. Therefore, these socks also provide the same effect as the socks of Example 11. In addition, the thumb pressing section 5T and the third finger pressing section 5I have the effect of unconsciously tensioning the body of the wearer HM, contrary to the ring finger pressing section 3D and the like. Therefore, if you wear the socks of Examples 14 and 15 having the thumb pressing part 5T or the thumb pressing part 5T and the forefinger pressing part 5I when training for walking or running, the muscles of your lower limbs will be tense and you will not be able to train. You can increase the effectiveness of your training. Therefore, the socks of Examples 14 and 15, like Example 11, received a B rating for "smoothness in walking and running" and an A rating for "stability in standing posture."
In addition, as in Example 14, the sock may be provided with only the thumb pressing part 5T, which has a higher effect of tensing the body than the middle finger pressing part 5M, but in Example 15 (Modified Embodiment 2, FIG. 11), By providing both the thumb pressing section 5T and the forefinger pressing section 5I, the effect of tensing the body of the wearer HM can be further enhanced, and the effects of training etc. can be further enhanced.

Note that Reference Example 1 is a sock in which the sock of Comparative Example 1 is provided with only a heel-internal malleolus line pressing portion 4A and a heel-lateral malleolus line pressing portion 4B. Further, Reference Example 2 is a sock in which a medial ankle line pressing part 4C and a lateral ankle line pressing part 4D are further provided in the sock of Reference Example 1, and the sock of Example 8 (Modification 3, see FIG. 12) This is also a sock with the midfoot vertical line pressing portion 13B removed. When the wearer HM wearing the socks of Reference Examples 1 and 2 assumes a standing posture, the heel-internal malleolus line pressing portion 4A and the heel-lateral malleolus line pressing portion 4B provided on the sock, or the medial malleolus line pressing portion 4C and the lateral malleolus line pressing part 4D, along the heel-medial malleolus line KIL and heel-lateral malleolus line KOL on the inside of the heel surface USH, the medial surface IS, and the lateral surface OS of the sole surface US of the wearer HM. This produces a tactile sensation of being pressed in a band-like manner. Thereby, the standing posture of the wearer HM can be further stabilized. Therefore, the "smoothness of walking and running" is rated E, which is the same as Comparative Example 1, but the "stability of standing posture" is rated C or B, which is two or three steps better than Comparative Example 1. It was evaluated.

<Embodiment 2>
In Embodiment 1 and the like described above, an example was shown in which the present technology was applied to a five-finger sock.
