Description

  The present invention relates to a leg supporter that is worn on a leg.

  Conventionally, as a leg supporter that is worn on the leg, for example, as shown in Patent Document 1, the range of motion is narrowed so that the ankle joint does not move, or as shown in Patent Document 2 It is known that the range of motion of the ankle joint is not restricted excessively and suppresses excessive movement.

  The supporter of Patent Document 1 is provided with a V-shaped fixing belt on the supporter body. The supporter body is attached to the ankle joint, and the fixing belt is wound around the joint in an 8-shaped form. Thus, the entire joint can be firmly fixed. In addition, the supporter of Patent Document 2 is provided with a belt-like connecting body in the vicinity of the outer fruit portion of a foot body that is shaped like a sock, and prevents the ankle from overturning by the connecting body. Since the range of motion of the joint is not forcibly limited by the flexible leg body, the leg can be moved smoothly.

  By the way, in recent years, an increasing number of elderly people are facing an aging society and have a state of musculoskeletal disorder called locomotive syndrome (also referred to as locomotive or musculoskeletal syndrome). When such a locomotive syndrome progresses, the joints become unsupported by muscles due to age-related muscle loss and bone strength decrease, joint pain increases, and bone mass decreases and is supported by muscles. It will be easy to break because it is lost. As a result, walking becomes difficult, resulting in lack of exercise. If the health condition deteriorates, it will cause a need for care. Therefore, there is a demand for a leg supporter that can supplement the function of muscles and assist walking.

  However, although the supporter shown in Patent Document 1 can stably fix the joint, the range of motion of the joint is remarkably narrowed, so that it is difficult to use it during walking. In addition, although the supporter shown in Patent Document 2 is flexible and easy to move, it has poor stability because the function of supporting the legs is weak, and it does not supplement the function of moving the legs, so it helps walking. Not a thing.

  The present invention has an object to solve such problems, and can smoothly move without greatly reducing the range of motion of the joint, and also exerts a propulsive force when walking to supplement the walking function. It is an object of the present invention to provide a leg supporter that can be used.

The present invention provides a leg supporter including a stretchable base having a sole, an instep, an ankle, and a lower leg.
One end portion is fixed at a portion from the wearer's mother's ball or the vicinity of the mother's ball to the center of the sole at the sole, and extends obliquely toward the outside of the wearer's heel, A band-like thumb-side band that is detachably fixed to the lower leg part through the outside of the ankle part and the rear side of the ankle part;
One end is fixed in a portion from the wearer's small ball or the vicinity of the small ball to the center of the plantar portion at the sole, and extends obliquely toward the inside of the wearer's heel, A band-shaped little finger side band that is detachably fixed to the lower leg part through the inside of the ankle part and the rear side of the ankle part,
The thumb side band and the little finger side band are members different from the base,
The thumb support band and the little finger band are leg supporters having an extension rate smaller than that of the base.

In such a leg supporter, the thumb side band is composed of a lower thumb side band in contact with the sole, and an upper thumb side band connected to the upper end of the lower thumb side band. The side band is thinner than the upper thumb side band, and the little finger side band includes a lower little finger side band in contact with the sole, and an upper little finger side band connected to an upper end of the lower little finger side band. Preferably, the lower little finger side band is thinner than the upper little finger side band. Also In such a leg supporter is further secured, part from the small趾球or small趾球vicinity of the wearer in the central portion of the foot bottom of the foot bottom, or in front of the wearer's heel An inversion band extending from the ankle portion to the front side and fixed to the ankle portion or the lower leg portion;
A part of the sole that extends from the wearer's mother ball or the vicinity of the mother ball to the center of the sole, or the front side of the wearer's heel, and extends from there to the front of the ankle. An outer band attached to the ankle part or the lower leg part,
It is preferable that the extension rate of the inner turning band and the outer turning band is smaller than that of the thumb side band and the little finger side band.

The sole includes a wearer's mother ball at the sole or a thumb side portion that develops a tightening force from the vicinity of the mother ball toward the outside of the heel, and a wearer's small ball or small ball at the sole. A little finger side portion that expresses tightening force from the vicinity of the Ryukyu toward the inside of the heel,
The elongation rate of the thumb side portion and the little finger side portion is based on the elongation rate of the rest of the sole, the instep, the ankle portion, and the crus portion excluding the thumb side portion and the little finger side portion. Is preferably small.

  The leg supporter of the present invention includes an elastic base having a sole part, an instep part, an ankle part, and a lower leg part, and can be worn and worn like a sock. For this reason, it can be easily used regardless of age. Further, the thumb side band and the little finger side band are fixed in a part from the vicinity of the wearer's mother ball to the center of the sole, or a part from the vicinity of the small ball to the center of the sole, and Since the stretch rate is smaller than the base, when worn on the legs, the tightening force from these bands acts in the vicinity of the main and small ball, causing the foot to bend (the toes move toward the sole) Power is generated. For this reason, since the force which kicks with a foot increases and strong propulsive force is obtained, it can walk easily. In addition, since the thumb side band and the little finger side band extend around the ankle part and extend to the lower leg after passing through the sole, a strong tightening force is obtained by the long band length, and the ankle joint is It can be supported stably.

  And, when providing an inversion band and an inversion band, suppress the excessive pronation of the ankle joint by the tightening force of the inversion band (the sole is facing excessively in the state where the lower leg is fixed) It is possible to prevent sprains effectively because it is possible to suppress excessive supination (the sole is directed toward the inside in the state where the lower leg is fixed) by the tightening force by the outer band. be able to. Further, the tightening force of the inversion band also has an effect of maintaining the arch shape of the arch, so that it is possible to more reliably absorb the impact received from the ground when walking. And, since the extension rate of the inner band and the outer band is smaller than the elongation rate of the thumb side band and the little finger side band and the tightening force is applied more strongly, the weight tends to be applied to the front side of the foot. The effect that it becomes easy to walk is also brought about.

  Hereinafter, a leg supporter according to the present invention will be described with reference to the drawings.

  1 to 3 show a first embodiment of the leg supporter according to the present invention (denoted by reference numeral 1). The illustrated leg supporter 1 is for the right leg and is shown worn on the right leg 100. In addition, although illustration is abbreviate | omitted, the leg supporter for left legs becomes a left-right symmetric relationship with respect to the right leg. In this specification and the like, “front side” is the toe side of the right leg 100, and “rear side” is the heel side of the right leg 100.

  The leg supporter 1 according to this embodiment includes a base 2, a thumb side band 3, and a little finger side band 4.

  The base 2 has a shape like a sock, and covers the sole, instep, ankle, and lower leg when worn on the right leg 100. The sole 2a, the instep 2b, and the ankle 2c are covered. The lower leg 2d is provided.

  On the front side of the base 2, five finger holes 2e1 to 2e5 are provided to expose the thumb to the little finger of the right leg 100, respectively (see FIG. 3A). Further, on the rear side of the base 2, a notch 2f for exposing the heel 101 of the right leg 100 is provided. A mouth contraction portion 2g for preventing the base 2 from slipping off the right leg 100 is provided above the lower leg portion 2d. The mouth contraction part 2g of this embodiment is located at about 1/2 of the length of the lower leg (length from the ankle to the knee) starting from the ankle. The position of the mouth contraction 2g may be the upper part of the bulge shin (under the knee), or the lower part of the bulge shin (above the ankle).

  The base 2 is formed of a stretchable fabric that is knitted with a flat yarn, a rib knitting, a tuck knitting, a floating knitting, etc., using, for example, a front yarn, a back yarn and an elastic yarn as a knitting yarn. A one-way stretch fabric (for example, a satin net) that has elasticity in any one of the directions, a 2-way stretch fabric (for example, a power net) that has elasticity in both directions, or the like can be used. In addition, it is possible to change the expansion / contraction rate by appropriately selecting the type of yarn and the knitting density, and it is also possible to improve air permeability and water absorption. In this embodiment, dough that is not easily stuffy is used. Further, the sole part 2a, the instep part 2b, the ankle part 2c, and the crus part 2d may be formed of the same cloth, but may be formed by using a plurality of cloths having different characteristics.

  The mouth contraction part 2g of the present embodiment is such that a string is passed through a loop-shaped hole formed by folding the upper end of the lower leg part 2d downward, and the outer diameter of the mouth contraction part 2g is reduced by pulling the string. It is trying to narrow. Further, a hook-and-loop fastener is provided at the end of the string so that the string can be pulled. In addition, you may make it the outer diameter of the opening contraction part 2g narrow through a loop-shaped hole through rubber | gum. Further, an anti-slip function may be added to the inner peripheral surface of the mouth contracting portion 2g. For example, synthetic resin is spotted on the inner peripheral surface of the mouth contracting portion 2g. Can be mentioned. Moreover, you may exhibit an anti-slip | skid function by the increase in frictional force using the cloth | dough which has an unevenness | corrugation on the surface while having elasticity.

  The thumb-side band 3 is stretchable and has a belt-like shape, and the extension rate along the longitudinal direction is smaller than the extension rate of the base 2 (the thumb-side band 3 is more than the base 2). It is difficult to stretch, and when both are stretched to the same length, the tightening force expressed in the thumb side band 3 is stronger than the tightening force expressed in the base 2). In order to change the tightening force, for example, the type of elastic yarn may be changed. Even if the same type, the mixing ratio of elastic yarns, the thickness of elastic yarns, and the knitting of elastic yarns may be changed. The density may be changed. It can also be realized by the presence or absence of processing that makes the fabric difficult to stretch, such as laminating, and by changing the thickness of the fabric (changing the thickness of the fabric itself or changing the number of fabrics to be stacked).

  Further, as shown in FIG. 3A, one end 3a of the thumb-side band 3 is fixed in the vicinity of the wearer's mother's ball 102 at the sole 2a. In the present embodiment, one end 3a is sewn and fixed to the sole 2a. In addition, as a fixing method, it is not limited to sewing, For example, you may use a hook-and-loop fastener. The thumb-side band 3 to which the one end 3a is fixed extends obliquely toward the outer side of the wearer's heel 101 as shown in FIG. 3 (a), and further, as shown in FIG. 1 (b). The other end 3b is fixed inside the lower leg portion 2d through the rear side of the ankle portion 2c via the vicinity of the outer heel (outer fruit) of 2c (preferably the rear side of the outer fruit). The other end 3b of the present embodiment employs, for example, a hook-and-loop fastener so that it can be detachably fixed to the base 2. In addition, you may make it adhere to the sole 2a by sewing similarly to the one end part 3a. The thumb-side band 3 is stretched when worn on the right leg 100, and the edges (longitudinal edges) on both sides of the thumb-side band 3 are not sewn in the present embodiment, but the thumb side. As long as the stretchability of the band 3 is not hindered, the base 2 may be sewn partially (or over the entire region).

  In addition, although the one end part 3a of this embodiment is being fixed to the vicinity of the heel ball 102, it shifts to the outer side of the wearer's heel 101 and reaches the center of the sole 2a from the vicinity of the heel ball 102. It may be fixed in between.

  The thumb-side band 3 of the present embodiment includes a lower thumb-side band 30 that contacts the sole 2 a and an upper thumb-side band 31 that is connected to the upper end of the lower thumb-side band 30. The lower thumb side band 30 is thinner than the upper thumb side band 31. Further, the tightening force as the thumb side band 3 is mainly expressed in the upper thumb side band 31.

  The little finger side band 4 has a stretch shape like the thumb side band 3 and has a belt shape, and the elongation rate along the longitudinal direction is smaller than that of the base 2. In addition, although the little finger side band 4 of this embodiment is formed with the same material as the thumb side band 3, you may form it with another material. In addition, the thumb side band 3 and the little finger side band 4 of the present embodiment are different members formed in a band shape, but an X-shaped member in which these members are integrated may be used.

  Further, as shown in FIG. 3A, one end portion 4a of the little finger side band 4 is fixed between the vicinity of the wearer's small ball 103 and the middle portion of the sole 2a in the sole 2a. Note that the position where the one end 4a is fixed may be close to the small ball 103 or close to the middle part of the sole 2a. In the present embodiment, the one end 4a of the little finger side band 4 is also fixed to the sole 2a by sewing. The one end 4a may also be fixed with a hook-and-loop fastener. The little finger side band 4 to which the one end 4a is fixed extends obliquely toward the inner side of the wearer's heel 101 as shown in FIG. 3 (a), and further, as shown in FIG. 1 (b). The other end portion 4b is fixed to the outside of the lower leg portion 2d through the rear side of the ankle portion 2c via the vicinity of the inner fruit of 2c. The other end 4b is also detachably fixed to the base 2. The little finger side band 4 is also stretched when worn on the right leg 100, and in this embodiment, both edges (longitudinal edges) of the little finger side band 4 are not sewn. As long as the stretchability of the side band 4 is not hindered, the base band 2 may be sewn partially (or over the entire area).

  The little finger side band 4 of the present embodiment is composed of a lower little finger side band 40 that is in contact with the sole 2 a and an upper little finger side band 41 that is connected to the upper end of the lower little finger side band 40. The lower little finger side band 40 is thinner than the upper little finger side band 41. Further, the tightening force as the little finger side band 4 is mainly expressed in the upper little finger side band 41.

  Thus, since the thumb side band 3 and the little finger side band 4 are stretched when worn on the right leg 100, tightening force is generated between the two bands in this state. As a result, a tightening force acts on the wearer's main ball 102 and the small ball 103 in the vicinity to produce a force that causes the foot to bend. Therefore, when walking, the force of kicking with the foot increases and strong propulsive force is generated. Can be obtained. Moreover, since the thumb side band 3 and the little finger side band 4 pass through the ankle part 2c so as to go around the ankle of the right leg 100 after passing through the sole part 2a, they further extend to the lower leg part 2d. A long band length provides a strong tightening force and can stably support the ankle joint. Further, the thumb side band 3 and the little finger side band 4 have a substantially symmetrical positional relationship with the ankle joint, and the balance is equal, so that the joint can be supported more stably. Further, this tightening force acts obliquely toward the center of the sole 2a with respect to the main ball 102 and the small ball 103, so that both approach each other and both approach the heel 101. In order to act, the effect which maintains the arch shape of an arch is also brought about. For this reason, the impact received from the ground when walking can be effectively absorbed. By the way, the human long peroneus muscle starts from the upper 2/3 of the radial head and the lateral surface of the radius, travels behind the external fruit, and stops at the first metatarsal bone of the sole. That is, since the thumb side band 3 extends along the long peroneal muscle from the sole 2a to the outside of the ankle 2c, the long peroneal muscle can be supported. For this reason, the load added to the long radius muscle can be reduced. Further, the ankle joint 3 can suppress excessive ankle gyration (the sole is directed toward the inside in a state where the lower leg is fixed), and the little finger band 4 can suppress the ankle joint. Excessive pronation (the sole of the foot is excessively outward when the lower leg is assumed to be fixed) can be suppressed.

  Furthermore, the fingers of the right leg 100 are exposed by the finger holes 2e1 to 2e5 provided in the base 2, and the surface on which the sole touches the ground can be easily grasped by the finger and can be kicked out strongly during walking, thereby making it easier to walk. . In addition, since the heel 101 is exposed by the notch 2f, the inside of the base 2 is less likely to be stuffy in combination with the above-described finger holes 2e1 to 2e5, and can walk comfortably. Further, since the thumb side band 3 and the little finger side band 4 are composed of the lower thumb side band 30 and the lower little finger side band 40 having a small thickness at the portion in contact with the sole part 2a, the bottom side 2a has a lower thumb side. The level | step difference of the site | part where the band 30 and the lower little finger side band 40 extend, and the other site | part is small. Thereby, the uncomfortable feeling transmitted to the sole when worn on the right leg 100 can be eliminated.

  Furthermore, since the other end 3b of the thumb side band 3 and the other end 4b of the little finger side band 4 can be detachably fixed to the base 2, the fixing position is changed according to the size of the wearer's leg. can do. In addition, it is possible to change the tightening force of the thumb side band 3 and the little finger side band 4 by changing the fixing position, and the above-described force for bending the foot can be obtained at a higher level. It can also be suitably used for sports athletes.

  The leg supporter 1 described above can further include various functions. For example, an inner turning band 5 or an outer turning band 6 as illustrated may be provided.

  The inner turning band 5 and the outer turning band 6 are elastic and have a band shape, and the elongation ratio is smaller than that of the base 2 and smaller than that of the thumb side band 3 and the little finger side band 4. It has become. That is, the tightening force expressed in the inner band 5 and the outer band 6 is larger than that of the base 2 and further larger than that of the thumb side band 3 and the little finger side band 4. Note that the inner band 5 and the outer band 6 of the present embodiment are formed of the same material, but may be formed of different materials.

  As shown in FIG. 3A, the one end portion 5a of the inner band 5 is fixed to the center portion of the sole portion 2a. It should be noted that the position where the one end portion 5a is fixed may be a portion from the vicinity of the wearer's small ball 103 to the center of the sole 2a, or the front side of the wearer's heel 101. Moreover, although the one end part 5a may adhere to the sole part 2a by sewing, it is preferable to attach it detachably, for example using a hook-and-loop fastener so that it can be removed according to a use scene. The inversion band 5 to which the one end portion 5a is fixed extends toward the front side of the ankle portion 2c as shown in FIGS. 1A and 3B, and the other end portion 5b of the inversion band 5 is It is fixed outside the lower leg 2d. The fixing position of the other end 5b is not limited to the outside of the crus 2d, and may be any part of the crus 2d, or may be fixed to the ankle 2c by shortening the length. Good. Moreover, although the other end part 5b of this embodiment may be fixed by sewing, it is preferable to fix it detachably using a hook-and-loop fastener etc. Further, when the one end portion 5a or the other end portion 5b is fixed by sewing, the edges on both sides (longitudinal edges) of the inversion band 5 are not hindered from being stretched when worn on the right leg 100. As long as it is possible, the base 2 may be sewn partially or over the entire area.

  Further, the inner turning band 5 of the present embodiment includes a lower inner turning band 50 that contacts the sole 2 a and an upper inner turning band 51 that is connected to the upper end of the lower turning band 50. The lower inner turning band 50 is thinner than the upper thumb side band 31. Further, the tightening force as the inversion band 5 is mainly expressed in the upper inversion band 51.

  One end 6a of the outer band 6 is fixed to the front side of the wearer's heel 101 as shown in FIG. In addition, you may adhere to the site | part from the vicinity of the main ball 102 to the center part of the sole part 2a. Moreover, although the one end part 6a may be fixed to the sole part 2a by sewing, it is preferable to fix it detachably using a hook-and-loop fastener. As shown in FIGS. 1 (a) and 3 (b), the outer band 6 to which the one end 6a is fixed extends toward the front side of the ankle 2c, and the other end 6b of the outer band 6b. Is fixed inside the lower leg 2d. The fixing position of the other end 6b may be any part of the crus 2d, and may be fixed to the ankle 2c by shortening the length. Moreover, although the other end part 6b of this embodiment may be fixed by sewing, it is preferable to fix it detachably using a hook-and-loop fastener etc. Similarly to the inner band 5, both side edges (longitudinal edges) of the outer band 6 may be partially or entirely as long as the extension when worn on the right leg 100 is not hindered. You may sew to the base 2 over.

  Further, the outer turning band 6 of the present embodiment is composed of a lower outer turning band 60 in contact with the sole 2 a and an upper turning band 61 connected to the upper end of the lower turning band 60. The lower outer turning band 60 is thinner than the upper outer turning band 61. Further, the tightening force as the outer band 6 is mainly expressed in the upper outer band 61.

  In such a leg supporter 1, when worn on the right leg 100, the inner band 5 and the outer band 6 are stretched together with the thumb side band 3 and the little finger side band 4. Will occur. Thereby, the leg supporter 1 also has the effects of the inner turning band 5 and the outer turning band 6 together with the effects of the leg supporter 1 described above due to the tightening force. In other words, the thumb side band 2a is acted on by a tightening force of the inward turning band 5 to force it inward, and by the tightening force of the inverting band 6, it acts on the outside. In combination with the effects of the band 3 and the little finger side band 4, it is possible to more reliably suppress excessive pronation and prolapse of the ankle joint. Further, since the arch of the right leg 100 is lifted by the tightening force of the inner band 5, the arch shape of the arch can be held more stably. And the extension rate of the inner band 5 and the outer band 6 is smaller than that of the thumb band 3 and the little finger band 4, and the tightening force acts more strongly, so that it is easier to apply to the front side of the foot during walking, making it easier to walk. The effect of becoming. The inner turning band 5 and the outer turning band 6 are composed of a lower inner turning band 50 and a lower outer turning band 60 having a thin portion in contact with the sole portion 2a, and the lower inner turning band in the sole portion 2a. Since the level difference between the portion provided with 50 and the lower outer turning band 60 and the other portion is reduced, the uncomfortable feeling transmitted to the sole when worn on the right leg 100 is eliminated.

  Note that the leg supporter 1 described above includes various bands formed differently from the base 2, but like the leg supporter 10 shown in FIGS. 4 to 6, the base itself has a band. It is also possible to have a function. The leg supporter 10 includes only a base 20 and includes a sole 20a, an instep 20b, an ankle 20c, and a crus 20d. Further, a mouth contraction portion 20g having the same configuration as that of the mouth contraction portion 2g described above is provided above the lower leg portion 20d.

  The base 20 of this embodiment is sewn on both sides of the right leg 100 around the ankle and lower leg of the wearer as shown in FIGS. 4 and 5, and as shown in FIG. 6 (a). The ankle / crus 21a that wraps around the sole and is sewn in front of the heel 101, and is sewn to the ankle / crus 21a covering the wearer's instep as shown in FIGS. As shown in (a), an instep portion 21b that wraps around the sole of the wearer, and extends obliquely from the base of the wearer's thumb through the center ball 102 and the center of the sole, the instep portion 21b and The thumb side portion 21c sewn on the ankle / crus portion 21a, the small ball 103 and the center of the sole starting from the base of the wearer's little finger, the instep portion 21b, the thumb side portion 21c, and the ankle The little finger side portion 21d sewn on the lower leg portion 21a, and the wearer's index finger and middle finger It extends between the thumb portion 21c and the little finger side portion 21d of the ring finger as a starting point is constituted by the intermediate portion 21e is sewn to the thumb portion 21c and a little finger portion 21d.

  The ankle / crus part 21a, the instep part 21b, the thumb side part 21c, the little finger side part 21d, and the intermediate part 21e are made of a stretchable fabric. Specifically, the ankle / crus part 21a is composed of a one-way stretch fabric that stretches along the direction of the wearer's ankle and crus, and the instep part 21b is oriented around the wearer's leg. Consists of a 1-way stretch fabric that stretches along. Further, the thumb side portion 21c is formed of a 1-way stretch fabric that expands and contracts in the direction from the main ball 102 to the outside of the heel 101, and the little finger side portion 21d extends and contracts in the direction from the small heel ball 103 to the inside of the heel 101. It consists of a 1-way stretch fabric. The intermediate portion 21e is composed of a two-way stretch fabric that expands and contracts in the direction from the wearer's index finger, middle finger, and ring finger to the heel 101, and expands and contracts in a direction crossing between the thumb side portion 21c and the little finger side portion 21d. Has been. Here, the extension rate of the thumb side portion 21c and the little finger side portion 21d is smaller than the extension rates of the ankle / lower leg portion 21a, the instep portion 21b, and the intermediate portion 21e. Further, the extension rate of the intermediate portion 21e is smaller than the extension rates of the ankle / crus portion 21a and the instep portion 21b in both directions.

  When the leg supporter 10 having such a configuration is put on the right leg 100, the thumb side portion 21c and the little finger side portion 21d are extended, and the wearer's mother ball 102 is near the outside of the heel 101. A tightening force acts, and in the vicinity of the small ball 103, the tightening force acts toward the inside of the eyelid 101. As a result, a force to bend the foot is generated, so that the propulsive force during walking can be increased. Further, this tightening force acts on the main ball 102 and the small ball 103 so that they approach each other and both approach the hook 101, so that the arch shape of the arch is maintained. . Further, the tightening force by the intermediate portion 21e works in two directions as described above, and acts so that the mother ball 102 and the small ball 103 come close to each other and both come close to the ball 101. Therefore, both the effect of increasing the propulsive force during walking and the effect of maintaining the arch shape of the arch can be further enhanced.

  Furthermore, the ankle / crus part 21a is composed of a one-way stretch fabric that stretches along the direction of the wearer's ankle and crus, and the stretch in the direction from the wearer's ankle to the knee is suppressed. In addition, excessive pronation or prolapse of the ankle joint is suppressed, and the ankle can be stably supported.

  When the leg supporters 1 and 10 described above are combined to form the leg supporter 11 shown in FIGS. 7 to 9, the effect of obtaining strong propulsive force during walking as described above and the ankle joint can be stabilized. It is possible to obtain the effect of supporting in a higher dimension.

  The specific embodiment of the leg supporter has been described above. However, the leg supporter according to the present invention is not limited to the above-described embodiment, and includes various modifications as long as the claims are followed. For example, five finger holes and notches provided in the base may be omitted, and a toe portion and a heel portion may be provided instead. Moreover, although the leg supporter shown in FIGS. 4 to 6 has been described as being composed only of a base, an inner turning band or an outer turning band shown in FIGS. 1 to 3 may be added.
