Description

  The present invention relates to a hallux valgus correction footwear. A user having a hallux valgus wears the hallux valgus correction footwear of the present invention, thereby relaxing and correcting the hallux of the user's hallux (thumb) and assisting the formation of a normal foot bone.

As the name suggests, the hallux valgus warps the outside of the body (the little finger), and the base ball (joint of the base of the heel) bends into a “K” shape. Say the symptoms. Symptoms are caused by shoes that do not fit in the foot and weakness, and open legs that result from a decrease in the height of the metatarsal arch from the metatarsal bone of the toe to the metatarsal of the little finger It is said that. When the hallux valgus symptoms progress, bones may deform, making walking difficult.
In the prior art, several hallux valgus correction footwear for the purpose of correcting a user's hallux valgus are known.

  As the first pattern, a so-called valgus inner crotch columnar structure type hallux valgus correction footwear may be mentioned. For example, JP-A-11-276203 and JP-A-11-169201 are known. These are provided with a columnar structure on the upper surface of the footwear corresponding to the inner thighs of the user's mother's heel and second heel (foot forefinger). By attaching the footwear in a state where the structure is sandwiched, the hallux that is valgus is corrected. Even when the user's mother's heel has hallux symptom, since the columnar structure is present, the inner heel of the heel cannot hit the columnar structure and bend in the valgus direction. In other words, the main rib is forcibly bent back by the columnar structure.

  As the second pattern, there is a so-called valgus belt correction footwear of a so-called annular belt arrangement direction correction type. For example, JP-A-2004-215870, JP-A-2003-33204, and JP-A-2002-345501 are known. These are provided with a ring-shaped belt on the upper surface of the footwear, and these are arranged in a normal heel position. The user corrects the hallux valgus by inserting and attaching the mother heel and the second heel to the determined annular belt. Even when the user's mother toe has hallux symptom, it is possible to apply a force to correct the hallux that has been hallux because the arrangement direction of the belt for forcibly inserting the mother toe is determined. .

  A third pattern includes a so-called hallux valgus correction supporter. For example, JP-A-11-76283 and JP-A-2003-290263 are known. These are provided with a supporter portion that wraps the hull and a main body portion that is wrapped around and fixed to the instep, and pulls the hull together with the supporter to the supporter main body side. Even when the user's mother's niece has hallux symptom, it is possible to apply a force to correct the hallux valgus via the supporter portion.

JP-A-11-276203 JP-A-11-169201 JP 2004-215870 A JP 2003-33204 A JP 2002-345501 A Japanese Patent Laid-Open No. 11-76283 JP 2003-290263 A

As described above, footwear for correcting hallux valgus is known in the prior art, but each has its own problems.
The first so-called valgus inner thigh columnar structure type hallux valgus-corrected footwear has a problem in that the bones of the tress are easily damaged. When the user's mother's heel has a strong hallux symptom, there is a columnar structure, so the inner limb of the mother's butt hits the columnar structure and forcibly bends it back. Since it keeps hitting strongly, it is easy to cause a problem that an excessive force is applied to the bones and the mother's mother is damaged.

The second so-called valgus-valley-corrected footwear in which the direction of the belt-shaped belt is disposed has a problem that the force to correct the valgus is not sufficient.
The former problem is caused by the following reasons. The direction of the arrangement of the belt-shaped belt is used to correct the hallux valgus correction footwear by inserting it into a specified ring-shaped belt, but the belt inner diameter requires a certain amount of play with respect to the outer diameter of the housing. In addition, the belt must have a certain degree of flexibility. This play gap works as a gap that allows the hallux to be crushed, and the correction force of the hallux cannot be sufficiently obtained (Japanese Patent Laid-Open No. 2002-345501).

  Further, an outer belt is provided on the outer edge of the main body and an inner belt is provided on the inner thigh, and these belts are connected to the main body to form an annular belt (Japanese Patent Application Laid-Open Nos. 2004-215870 and 2003-33204). Gazette), it is difficult to tie the outer belt and the inner belt without play to the mother's body, so play is likely to occur, and the gap of this play works as a gap that allows the mother's hallux to be crushed. In other words, when linking the outer belt and inner belt, the outer belt must be pulled inward and the inner belt must be pulled outward, but the pulling directions of the two collide with each other. difficult. Therefore gap of this play really tends to occur play would work as a gap to allow the valgus of the hallux.

The third so-called hallux valgus correction supporter has a problem in that the correction direction applied to the hallux is an oblique rearward direction, and the correction force cannot be said to be the correct direction.
The hallux valgus correction supporter wraps the mother's heel with a supporter portion and pulls the supporter around the instep. That is, the direction in which the supporter is pulled is an obliquely rearward direction, and is not the direction opposite to the valgus direction. Therefore, when the user's mother's mother has hallux symptom, it cannot be said that the tension applied to correct the hallux is appropriate. This hallux valgus correction supporter is intended to prevent the hallux from overlapping the first hall and to suppress the progression of hallux symptom symptoms. It does not give direction correction.

  In view of the above-mentioned problems, the present invention can be securely worn in a direction opposite to the valgus direction while fitting and wrapping the valgus with a user who has a hallux valgus. The purpose is to provide a valgus-corrected footwear that gives proper corrective force and helps to form normal foot bones.

  In order to achieve the above object, the hallux valgus-corrected footwear of the present invention has a first inner belt piece whose one end is fixed to the upper part of the inner periphery of the footwear upper surface (near the side of the eyelid) and one end of the outer periphery of the footwear upper surface. A first outer belt piece fixed to the upper part (near the little finger) is provided, the first inner belt piece and the first outer belt piece are connected to each other, and the amount of play on the toe of the foot is adjusted. However, the first belt covering from the user's mother toe to the little finger, the through hole formed in the first inner belt piece in the vicinity of the upper surface of the mother's heel, and one end of a normal shape of the upper surface of the footwear bottom A thigh correction belt fixed to a portion where the inner thigh of the main tread is to be positioned, the other end penetrating the through hole and led from the back side to the outer side of the first inner belt piece, The other end of the correction belt is against the user's hallux Positive tension while adjusting to give a reasonably tension (direction opposite to the valgus direction), the other end was that allowed to lock in the tensioning position.

  With the above structure, the first correction belt fixed so as to cover the upper upper surface of the footwear bottom can be easily and firmly pulled and locked to the correction belt guided to the outer surface through the through hole. be able to. In other words, since the first inner belt piece is fixed to the outer peripheral edge of the upper surface of the footwear via the first outer belt piece, the first inner belt piece is pulled outward (toe with little toe), while the mother Pull the other end of the wrinkle correction belt inward (toe side). Since the mother hair correction belt penetrates the first inner belt piece through the through hole, both can be firmly fastened. Moreover, since the other end of the correction belt is led to the front side of the first inner belt piece, it can be easily pulled by hand, and the correction force can be sufficiently applied to the binding.

  As a variation, the hallux valgus-corrected footwear of the present invention is further provided with a second inner belt piece having one end fixed to the inner peripheral middle portion (near the side of the baseball) of the footwear bottom upper surface and one end outer peripheral edge of the footwear upper upper surface. A second outer belt piece fixed in a middle part (near the fifth Ryukyu side), the second inner belt piece and the second outer belt piece are connected to each other, and the user's mother Ryukyu A second belt covering from the first to the fifth Ryukyu can be provided, and the second inner belt piece can apply tension to the outer side (little finger side) of the user's mother Ryukyu. is there.

  With the above configuration, the second belt can apply a force for correcting the overhang to the main ball that is bent into the shape of the letter “ku”, which is one of the symptoms of hallux valgus.

  As a further variation of the hallux valgus correction footwear of the present invention, the upper surface of the footwear bottom has an inner vertical foot arch (arch arch), an outer vertical foot arch (small finger side arch), and a horizontal foot arch that should have a normal human foot bone shape. It is also possible to have a hill-like convex shape corresponding to (Metathazar arch) and a concave shape corresponding to the user's heel.

  With the above configuration, formation of an inner longitudinal footbow, an outer longitudinal footbow, and a lateral footbow that should have a normal human footbone shape on the sole is promoted, and it is possible to suppress the progression of symptoms of hallux valgus.

The hallux valgus correction footwear of the present invention can contribute to the correction of the hallux valgus by wrapping the entire hallux valgus and firmly applying a force for correcting the hallux in the direction opposite to the direction of the hallux.
In addition, it is possible to promote the formation of an inner longitudinal footbow, an outer longitudinal footbow, and a lateral footbow that should have a normal human footbone shape on the sole, and to suppress the progression of symptoms of hallux valgus.

Hereinafter, embodiments of the hallux valgus correction footwear of the present invention will be described with reference to the drawings. However, it goes without saying that the technical scope of the present invention is not limited to the specific shapes and numbers shown as specific examples in the following embodiments.
In the description of the specification, the mother's heel is the toe's thumb, the second heel is the forefinger of the foot, the fifth heel is the toe's little finger, Is the joint at the base of the toe of the foot (joint of the proximal phalanx and metatarsal bone), and the fifth Ryukyu is the joint at the base of the little toe (joint of the proximal phalanx and metatarsal bone) ).

The example of the hallux valgus correction footwear of this invention concerning Example 1 is shown.
In addition to the first belt (first inner belt piece and first outer belt piece) covering the toes from the mother toe to the fifth toe, the hallux to correct the hallux as shown in Example 1 It is equipped with a correction belt. The configuration example of the first embodiment further includes a second belt (a second inner belt piece and a second outer belt piece) that covers the base ball to the fifth ball.

FIG. 1 to FIG. 3 are views showing a hallux valgus correction footwear 100 according to a first embodiment. Here, footwear for the right foot is shown. The footwear for the left foot may be symmetrical with the footwear for the right foot. In the case of footwear for the right foot, the inner peripheral side refers to the left side and the outer peripheral side refers to the right side.
FIG. 1 is a diagram showing a state in which all the belts are tied and wearing on the feet is completed. From left to right, a left side view, a plan view, and a right side view are shown in order.
2A is a view showing a state in which the first inner belt piece 10 and the first outer belt piece 20 are disconnected from the state shown in FIG. 1, and FIG. 2B is a view shown in FIG. It is a figure which shows the state which removed the main body correction belt 30 from the through-hole 11 from the state.
FIG. 3 is a view showing a state where all the belts are removed.

  As shown in FIGS. 1 to 3, a first inner belt piece 10, a first outer belt piece 20, and a hallux valgus correction belt 30 are provided on the upper surface of the footwear bottom 80. Further, a second inner belt piece 40 and a second outer belt piece 50 are provided in the middle of the upper surface of the footwear bottom 80. The first inner belt piece 10 and the first outer belt piece 20 form a first belt, and the second inner belt piece 30 and the second outer belt piece 40 form a second belt. In this example, a third inner belt piece 60 and a third outer belt piece 70 are provided in the middle of the upper surface of the footwear bottom 80 (in the vicinity of the side of the ankle instep) to fix the footwear to the ankle instep. A belt is also provided.

  One end of the first inner belt piece 10 is fixed to the upper part of the inner peripheral edge of the upper surface of the footwear bottom 80 (in the vicinity of the side of the toe). One end of the first outer belt piece 20 is fixed to the upper part of the outer peripheral edge (near the fifth heel side) of the upper surface of the footwear bottom 80. Here, although the fixing method is not limited, for example, the ends of the belt pieces are sewn and fixed to the peripheral portion of the upper surface of the footwear bottom 80 by using a thick thread. An adhesive for leather can also be used.

  The first inner belt piece 10 and the first outer belt piece 20 can be connected to each other. Although the method to tie is not specifically limited, For example, what is called a detachable tape is provided in each of the back surface of the 1st inner side belt piece 10 and the outer surface of the 1st outer side belt piece 20, and both shall be freely detachably locked. be able to. Moreover, a string may be provided instead of the detachable tape, and both may be connected by the string.

  One end of the hallux valgus correction belt 30 is fixed to a portion of the upper surface of the footwear bottom 80 where the inner thigh of the normal shape of the heel should be located. In the present invention, “the portion where the inner thigh of the normal shape of the main thigh should be located” includes “the vicinity of the position adjusted slightly to the inner periphery side than the portion where the normal shape of the inner thigh of the main thigh should be located”. Slightly broad range. The present invention also includes a device for widening the adjustment range of the magnitude of the hallux valgus correction effect. The device is as follows. The magnitude of the correction effect of the hallux valgus correction described later is determined by the fixing position of the one end of the hallux valgus correction belt on the upper surface of the footwear bottom 80 and the degree of tightening by pulling the other end of the hallux valgus correction belt. By applying a bias in advance so that the position on the upper surface is slightly on the inner peripheral edge side of the inner crotch position of the normal shape of the main body, the width of the adjustment range by pulling the other end of the latter hallux valgus correction belt is It will be able to handle a wide range of products from “slow correction power” to “tight correction power”. As hallux valgus correction progresses and hallux symptom decreases, there is a case where the pulling force to the part where the inner thigh of the normal shape of the mother's heel should be located does not provide sufficient correction force to continue further correction. possible. Therefore, if pulling to a position near the position adjusted to the inner peripheral edge side slightly from the portion where the normal shape of the inner thigh should be positioned, correction force can be applied until the hallux valgus is completely healed. .

  Next, the through hole 11 will be described. The first inner belt piece 10 has a through-hole 11 in the vicinity where the upper surface of the main body is located. The through-hole 11 is a hole for allowing the hallux valgus correction belt 30 to pass through from the back surface side of the first inner belt piece 10 to the outer surface side. As shown in FIGS. 2A to 2B, the other end of the hallux valgus correction belt 30 is inserted into the through hole 11 and guided from the back surface side of the first inner belt piece 10 to the outer surface side. In this way, by passing the hallux valgus correction belt 30 through the first inner belt piece 10 through the through hole 11, they can be pulled in opposite directions without colliding with each other. Moreover, the 1st inner side belt piece 10 and the hallux valgus correction belt 30 can be fastened mutually. Further, since the other end of the hallux valgus correction belt 30 is guided to the outer surface side of the first inner belt piece 10, the other end of the hallux valgus correction belt 30 is easily pulled in the correction direction (inner peripheral edge side) with the fingers of the hand. be able to.

  Incidentally, the position of the through hole 11 is set on the first inner belt piece 10 on the first inner belt piece 10 in accordance with the idea of providing a bias on the inner peripheral edge side of the position on the upper surface of the footwear bottom 80 of the above-described hook correction belt. A device can be devised in which a bias is provided as a position slightly closer to the inner peripheral edge than the vicinity where the upper surface is located.

  Although the other end of the main body correction belt 30 is detachably locked at an arbitrary position on the outer surface of the first inner belt piece 10, the method of locking is not particularly limited. For example, a removable tape is provided on the back surface of the other end of the correction belt 30 and a removable tape is also provided on the outer surface of the first inner belt piece 10 so that both can be freely attached and detached. can do.

Here, the principle of fixing by mutual tightening by the first belt and the reed correction belt 30 in the present invention will be described.
The upper diagram of FIG. 5A shows the relationship between the belts by taking out only the first belt portion. The lower diagram of FIG. 5A is a diagram schematically showing the state of the upper diagram. The first inner belt piece 10 is locked to the first outer belt piece 20 so that they are connected to each other. One end of the first inner belt piece 10 and one end of the first outer belt piece 20 are the bottom of the footwear. It is fixed to 80. Since both of these are engaged with each other, a solid base connecting the left and right ends of the footwear bottom is formed. It can be seen that the hallux valgus correction belt 30 is led from the back surface of the first inner belt piece 10 to the outer surface side through the through-hole 11, and can be firmly tightened in a form of crossing the base. Further, when the shape of the through-hole 11 and the shape of the hallux valgus correction belt 30 are substantially the same and there is sufficient skin-to-skin friction between the two, the stability is further enhanced.

FIG. 5B schematically shows a case in which only the first inner belt piece 10 is provided and the main body correction belt 30 is locked on the first inner belt piece 10 so as to be wound around without crossing the inner belt. FIG. In this case, the other end of the first inner belt piece 10 is not connected to the right end of the footwear bottom 80 but is in a idle state, and is not in a solid state as a base. Furthermore, the main body correction belt 30 is locked on the first inner belt piece 10 so as to be wound around without crossing the inner belt, and is cross-tightened tightly as shown in FIG. is not. Moreover, when winding the main body correction | amendment belt 30 with respect to the 1st inner side belt piece 10 of the idle state from the top without crossing, it is difficult to latch both without gap.
Based on such a principle, the first belt (first belt) is compared with a belt in which the first belt is not covered from the inner peripheral edge to the outer peripheral edge of the upper surface of the footwear bottom 80, and only the periphery of the heel is covered with the belt from the left and right. The inner belt piece 10 and the first outer belt piece 20) are fixed to both the inner and outer peripheral edges of the upper surface of the footwear bottom 80, and from the back side of the first belt piece 10 to the outer surface side through the through holes 11. The thing of this invention which tightens the guide | lead-up correction | inclination belt 30 has the structure where the tightening force was strong and was stable.

Next, the second belt will be described.
As shown in FIGS. 1 to 3, one end of the second inner belt piece 40 is fixed to an inner peripheral middle part (near the side of the baseball) of the upper surface of the footwear bottom 80. One end of the second outer belt piece 50 is fixed to the middle portion of the outer peripheral edge (near the fifth Ryukyu side) of the upper surface of the footwear bottom 80. Here, although the fixing method is not limited, for example, the ends of the belt pieces are sewn and fixed to the peripheral portion of the upper surface of the footwear bottom 80 by using a thick thread. An adhesive for leather can also be used.

  The second inner belt piece 40 and the second outer belt piece 50 can be connected to each other. The method of binding is not particularly limited. For example, as shown in FIG. 3, a ring-shaped metal fitting 41 is provided at the tip of the other end of the second inner belt piece 40, and the tip of the other end of the second outer belt piece 50. Is passed through the ring-shaped metal fitting 41, folded back to the outer peripheral edge side (fifth heel side) of the footwear and pulled, and the back surface of the second outer belt piece 50 is locked to the surface of the second outer belt piece 50 (FIG. 2). State). The second inner belt piece 40 is pulled to the outer peripheral edge side by the second outer belt piece 50 through the ring-shaped metal fitting 41, and the second outer belt piece 50 is pulled to the inner peripheral edge side through the ring-shaped metal fitting 41. It becomes a device. Thus, by folding and pulling the second outer belt piece 50 through the ring-shaped metal fitting 41, a stronger tightening effect can be obtained, and the second inner belt piece 40 and the second outer belt piece 50 can be combined. Can be tied strongly. Since the second inner belt piece 40 is in contact with the main ball, the force to correct the main ball protruding to the inner periphery side by deforming into a "<" shape due to the hallux valgus is firmly fixed to the outer periphery side. Can be given.

  The method of locking the back surface of the other end of the second outer belt piece 50 and the outer surface of the second outer belt piece 50 is not particularly limited, but each is provided with a so-called detachable tape so that both can be freely attached and detached. It can be locked. Moreover, a string may be provided instead of the detachable tape, and both may be connected by the string.

Next, a procedure for wearing the hallux valgus correction footwear 100 will be described.
First, from the state of FIG. 3, the user's sole is placed on the upper surface of the footwear bottom 80, and the second belt (the second inner belt piece 40 and the second outer belt piece 50) is attached to the user's mother's heel. From the ball to the fifth Ryukyu, the third belt (the third inner belt piece 40 and the third outer belt piece 50) is hung on the instep of the user.
The other end of the second outer belt piece 50 is passed through the ring-shaped metal fitting 41 at the tip of the second inner belt piece 40, and then folded back to the outer peripheral edge side (fifth side) and tightened. The tip of the end is locked onto the outer surface of the second outer belt piece 50 to tie the second inner belt piece 40 and the second outer belt piece 50 together. Since the second inner belt piece 40 is strongly tightened, a strong correction force can be applied to the outer side (the little finger side) with respect to the main ball that is bent in the shape of the “<” of the user.
In order to fix the entire footwear to the ankle instep, the third inner belt piece 60 and the third outer belt piece 70 are connected to each other to fix the entire footwear to the ankle instep.
When the second belt and the third belt are tied together and locked, the state shown in FIG. 2 is obtained.

Next, while wrapping the user's mother's torso, the main body correction belt 30 is inserted into the through hole 11 of the first inner belt piece 10 to obtain the state shown in FIGS. 2 (b) to 2 (a). .
It should be noted that this procedure can be omitted if the mother hair correction belt 30 remains inserted into the through hole 11 from the beginning. In other words, when the user takes off the hallux valgus correction footwear 100, even if the user does not completely remove the hallux correction belt 30 from the through hole 11, the user can remove the hallux correction footwear 100 and loosen it in a state where it is inserted to create the gap 100. If it can be removed from the through hole 11, it is not necessary to completely remove the main body correction belt 30 from the through hole 11. In this case, this is because the next time the mounting is performed, the correction belt 30 is inserted into the through hole 11.

Next, the first belt is put on the toe of the user's foot.
While placing the first outer belt piece 20 on the toes and further pulling the other end of the first inner belt piece 10 to the right side (the little toe side), the amount of play on the toe of the user is adjusted. Cover from mother toe to toe. The first inner belt piece 10 and the first outer belt piece 20 are connected at this position. For example, the detachable tape on the back surface at the other end of the first inner belt piece 10 is engaged with the detachable tape on the surface of the first outer belt piece 20, and both are tied and fixed. The state shown in FIG. 1 is obtained.

Next, as shown in FIG. 4, the main body correction belt 30 is pulled according to the correction degree of the user's main body and is locked on the outer surface of the first inner belt piece 10.
With the fingers of the hand while adjusting the other end of the correction belt 30 led out from the through hole 11 to the outer surface of the first inner belt piece 10 so as to give an appropriate tension to the valgus Pull and lock the other end on the outer surface of the first inner belt piece. Thereby, it is possible to apply a force in the direction of correcting the hallux (in the direction of the inner peripheral edge) to the hallux that is valgus while adjusting it appropriately.
As shown in FIG. 4, the hallux valgus-correcting footwear 100 of the present invention firmly applies a force to correct the hallux in the direction opposite to the valgus direction while wrapping the entire hallux valgus. Can be adjusted flexibly. An ideal hallux valgus can be corrected without damaging the bones of the mother's body.

The hallux valgus correction footwear 100 according to the second embodiment further has an uneven shape for correcting the hallux valgus on the upper surface of the footwear bottom 80.

  In the second embodiment, an example will be described in which the footwear bottom 80 is separable as an insole. FIG. 6 is a diagram schematically illustrating a state in which the insole 80 of the hallux valgus correction footwear 100 according to the second embodiment is taken out. The upper surface of the insole 80 corresponds to an inner longitudinal foot arch (arch arch), an outer longitudinal foot arch (small finger side arch), and a lateral foot arch (metatarsal arch) that a normal human foot bone shape should have 3 Two hill-shaped convex shapes 81-83 are provided. FIG. 7A shows a longitudinal section taken along line A1-A1 in FIG. 6, FIG. 7B shows a longitudinal section taken along line A2-A2, and FIG. 7C shows a transverse section taken along line A3-A3. On the upper surface of the insole bottom 80 of the hallux valgus correction footwear 100, as shown in FIG. 7A, a convex shape 81 corresponding to the inner vertical foot arch (arch arch) is provided. Moreover, as shown in FIG.7 (b), the convex surface shape 82 corresponding to an outer vertical foot arch (little finger side arch) is provided. Moreover, as shown in FIG.7 (c), the convex surface shape 83 corresponding to a lateral foot arch (metathazaar arch) is provided.

These three arches, the inner longitudinal arch, the outer longitudinal arch, and the transverse arch, are important in maintaining the normal shape of the foot bones. If this arch breaks down, it is thought that it will lead to the development of hallux valgus. Yes. Therefore, the concave and convex shapes 81 to 83 that help form these arches are provided on the upper surface of the footwear bottom 80.
By having the concave and convex shapes 81 to 83 on the upper surface of the footwear bottom 80, a synergistic effect with the correction of hallux valgus by the hallux valgus correction belt 30 described in the first embodiment can be expected.

  Although the preferred embodiments of the present invention have been illustrated and described above, the present invention is not limited to the specific shapes of the above-described embodiments, and various modifications can be made without departing from the technical scope of the present invention. It will be understood that this is possible. Therefore, the technical scope of the present invention is limited only by the description of the appended claims.
