  The present invention relates to a correction strap which has a function of pressing the metatarsal part in the foot width direction, a toe extension or a dorsiflexion function, and is preferably used for correcting hallux valgus or preventing falls, and a foot correction sock having the same.

  A characteristic case of hallux valgus is that it is away from the direction of the central axis of the body. Regarding this phenomenon, looking at the internal skeleton, hallux valgus, thickening of the head of the first metatarsal bone, lateral metastasis of the seed bone, or varus of the first metatarsal bone occurred as factors of hallux valgus Examples include an increase in the first metatarsal head, abnormalities in the tarsal joint of the first metatarsal, abnormalities in the abductor and adductor muscles, the length of the first metatarsal bone, or relaxation of the ligament.

  In particular, in the hallux valgus, paying attention to the fact that the metatarsal joint is open and causes the varus of the first metatarsal bone, the metatarsal part is oriented in the foot width direction (perpendicular to the longitudinal direction of the foot). Various hallux valgus correction tools having a pressing function have been proposed. For example, in Patent Document 1, a tubular main body that is formed of a knit fabric that expands and contracts in the width direction of the foot, and a stepped portion of the foot is inserted, and a metatarsal root portion in the stepped portion is tightened; A knitted fabric that expands and contracts in the longitudinal direction of the foot, is attached to the inner end side in the distal width direction of the cylindrical main body, and has a bag-like portion on the distal end side and an opening on the lower side in the second finger direction. A foot supporter having a one-finger insert has been proposed.

  Patent Document 2 discloses a sock for correcting hallux valgus, in which a part that abuts on the middle foot joint part of the foot and the base part of the fifth metatarsal is made of a member that is more elastic than the other part. A bag part to be inserted is formed on both sides of the toe, and the thumb and little finger are expanded outward by the force of pressing the metatarsal joint part and the fifth metatarsal base part, and the lateral arch is reproduced on the sole of the foot Socks that correct the balance of the feet so as to balance the entire sole have been proposed.

  Further, Patent Document 3 includes five fingers that individually wrap the five toes, and a metatarsal support that corrects the metatarsal in a convex arch shape, and includes a metatarsal support. Has proposed a foot garment having an elastic elastic body that elastically expands and contracts at least the metatarsal sole. Patent Document 4 proposes a sock having a mouth rubber portion knitted with a flat knitting in which rubber knitting or rubber yarn is inserted in the vicinity of contact with the middle foot joint. And in patent document 5, the direction of a stitch is the 1st metatarsal bone so that the force which presses a metatarsal bone part may act on the 1st metatarsal bone head and the 5th metatarsal base part. A hallux valgus and socks for correcting the varus little finger knitted in an oblique direction from the bone head to the base of the fifth metatarsal bone have been proposed.

  Hereinafter, embodiments for carrying out the invention will be described with reference to the drawings. The structure of the correction strap according to the present invention is shown in FIG. As shown in FIG. 1, the orthodontic strap 10 of this example includes a knit fabric portion 11 that covers the periphery of the metatarsal from the sole to the side of the foot, and a rubber fabric portion 13 (13A connected to both ends of the knit fabric 11). 13B) and engaging portions 17 and 18 for engaging the end portions of the rubber fabric portion 13. The knit fabric portion 11 has a slit 15 in the foot width direction in the plane.

  The knit fabric portion 11 is a portion where the knit fabric is knitted by, for example, knitting. The knitted fabric portion 11 is knitted so as to have a relatively small elongation. The degree of expansion / contraction of the knitted fabric portion 11 is knitted to 60 to 150% in terms of elongation.

  The length of the knitted fabric portion 11 is sufficient if it covers the circumference of the metatarsal from the sole to the side of the foot as described above, and is usually long enough to enter the instep from the side of the foot. The Thereby, even when the height of the instep portion varies depending on the person, the knit fabric portion 11 can be reliably covered from the sole to the side of the foot.

  The width of the knitted fabric portion 11 has a width that covers the first metatarsal bone head to the base of the fifth metatarsal bone, and a width that covers the entire metatarsal from the periphery. Note that the edge 11a of the knit fabric part 11 and the edge 11b of the slit 15 are preferably reinforced.

  The rubber fabric portion 13 is made of flat rubber, for example. The rubber fabric portion 13 is an easily stretchable portion, and the degree of expansion / contraction can be 200 to 400% in terms of elongation. The elongation rate of the rubber fabric portion 13 can be 2.0 to 4.0 times, preferably 2.5 to 3.5 times that of the knit fabric.

  The length or width of the rubber fabric portion 13 is appropriately set so that the amount of pressing force applied in the foot width direction of the knit fabric portion 11 when the end portion of the rubber fabric portion 13 is engaged becomes an appropriate size. It is decided. Note that the length of the rubber fabric portion 13 is appropriately determined depending on the method of use of the orthodontic strap described below.

  The slit 15 is provided in the foot width direction in the plane of the knit fabric portion 11 as described above, and the position thereof is preferably the central portion of the knit fabric portion 11. In addition, the length of the slit 15 is preferably substantially equal to the foot width. The opening width (B) of the slit 15 is appropriately determined. For example, it is 5 to 15 mm.

  The engaging portions 17 and 18 may be any members that are fixed so that the end portion of the rubber fabric portion 13 does not loosen during use of the correction strap 10. The engaging portions 17 and 18 can be constituted by, for example, a hook-and-loop fastener.

  The orthodontic strap 10 is used as follows. For example, as shown in FIG. 2, the orthodontic strap 10 is used so as to be wound around the metatarsal bone. 2A shows a state seen from the front side of the foot 50, and FIG. 2B shows a state seen from the back side of the foot 50. As shown in FIG. 2 (a), the knitted fabric portion 11 covers the circumference of the metatarsal from the sole to the side of the foot, and the rubber fabric portions 13A and 13B are engaged by the engaging portions 17 and 18 at the instep. Are combined.

  As shown in FIG. 2B, the upper edge of the upper portion 11c of the correction strap 10 is located along the roots of the first and fifth footpads, and the lower edge of the lower portion 11d is substantially at the base of the middle foot. It is in a position along. The slit 15 extends over the foot width, and the opening width is enlarged or reduced by the movement of the footpad.

  The orthodontic strap 10 is attached to the foot by providing a slit 15 in the knit base 11 that presses against the metatarsal bone, and the slit 15 whose opening width is enlarged or reduced by the vertical movement of the toes. There is little feeling of pressure, and it can be worn for a long time. Further, the positional movement of the upper part 11c and the lower part 11d of the knit base part 11 can be suppressed, and fluctuations in the pressing position with respect to the metatarsal bone part can be suppressed. And, there is no harmful effect that makes it easy to bend the toes like a conventional device for correcting hallux valgus.

  Further, as shown in FIG. 3, the orthodontic strap 10 can be used with rubber fabric portions 13A and 13B connected to both ends of the knitted fabric portion 11 intersecting at the instep and rotating the ankle. In this case, there is an effect of lifting the foot upward with the ankle joint at the ankle as a fulcrum and the toe portion with which the knit fabric portion 11 is in contact as an action point. Thereby, it is possible to prevent the patient with hallux valgus from falling over by pulling the toe on a small step or the like, and the correction of hallux valgus can be promoted by the dorsiflexion function caused by the lifting action.

  Such a function of the correction strap 10 is effectively exhibited when the correction strap 10 is always mounted at a predetermined position and a predetermined pressure or force is applied to the foot for a long time. For this purpose, as shown in FIG. 4, there is a foot correction sock having a configuration in which the center portion of the correction strap 10 is fixed to a position corresponding to the third foot base portion of the sole side of the sock and is extended outward and inward. preferable.

  As shown in FIG. 4, the orthodontic sock 100 has the straightening strap 10 fixed to the sock 30 by the fixing portion 19. The orthodontic strap 10 of this example includes a knit fabric portion 11 that covers the circumference of the metatarsal bone from the sole to the side of the foot, rubber fabric portions 13 (13A, 13B) that are connected to both ends of the knit fabric 11, and their An engaging portion 17 (17A, 17B) for engaging an end portion of the rubber fabric portion 13 and an engaging portion 18 are provided. A slit 15 in the foot width direction is provided in the plane of the knit fabric portion 11. The engaging portion 18 is provided on the back side of the ankle portion 33 of the sock 30. The engaging portions 17A, 17B, and 18 can be constituted by, for example, a hook-and-loop fastener.

  The fixing portion 19 for fixing the correction strap 10 to the sock 30 is not easily displaced from the sock 30 and the knit base portion 11 of the correction strap 10 is deformed evenly and has a required pressing force in the foot width direction with respect to the metatarsal portion. The position is not particularly limited as long as the position can be given. For example, the fixing portion 19 for fixing the correction strap 10 to the sock 30 is in the center portion of the correction strap 10, and the upper center portion of the slit 15 of the knit fabric 11 and the position corresponding to the third foot heel portion of the sole side of the sock 30 In other words, it is preferable that the portion entering the sole portion 35 is fixed at the center of the boundary between the sock portion 36 and the sole portion 35. The method for fixing the correction strap 10 to the sock 30 is not particularly limited. For example, as shown in FIG. 4, it can be sewn into two lines in the well direction.

  The orthodontic strap 10 of this example is preferably integrated with the sock 30 when the sock 30 is worn, and the portion in contact with the sock 30 is preferably subjected to anti-slip treatment. Thereby, when the leg correction socks 100 are worn, problems such as the sock 30 slipping between the correction straps 10 due to the movement of the legs and causing sprains can be solved.

  The sock 30 is preferably composed of a low stretch knitted fabric portion covering the instep portion 31, and a high stretch knitted fabric portion covering the ankle portion 33, the heel portion 34, the sole portion 35, and the sock portion 36. As a result, when the leg sock 100 is worn, a force capable of lifting the tip of the toe acts by the low stretch knitted fabric portion covering the instep portion 31 and can promote the extension of the toe. .

  The degree of expansion / contraction of the low-stretch knitted fabric portion can be 30 to 100% in terms of elongation, and the degree of expansion / contraction of the high-stretch knitted fabric portion can be 80 to 200% in terms of elongation. The elongation rate of the highly stretchable knitted fabric can be 1.0 to 3.0 times, and preferably 1.5 to 2.5 times that of the low stretch fabric.

  As shown in FIG. 5, the present leg sock 100 is attached so that the rubber fabric portions 13A and 13B connected to both ends of the knit fabric portion 11 intersect at the instep portion 31 and the ankle portion 33 circulates. used. When the leg sock 100 is worn, the upper edge of the knit fabric part 11 substantially coincides with the edge of the tabi part 36, and the fixing part 19 of the knit fabric part 11 is the third foot on the sole side of the sock 30 It is in a position corresponding to the root of the Sone. The opening width of the slit 15 is enlarged or reduced according to the movement of the toes. Thereby, the position movement of the upper part 11c and the lower part 11d of the knit fabric part 11 is suppressed. Further, it is possible to suppress fluctuations in the tightening force of the knit fabric portion 11 and to suppress the feeling of pressure.

  In the leg correction socks 100, by adjusting the engagement position between the engagement portions 17A and 17B and the engagement portion 18 of the rubber fabric portion 13, the tension acting on the rubber fabric portions 13A and 13B is adjusted, and the foot A twisting force can be applied to the surface. Therefore, for example, in the case of a person who is easily subject to body pressure on the outer surface of the foot, if the tension of the rubber fabric portion 13A is greater than the tension of the rubber fabric portion 13B, the body pressure acting on the outer surface of the foot will be increased. The balance of the foot can be improved by reducing the body pressure. In addition, the risk of falls and sprains can be reduced.

  As described above, the foot correction socks according to the present invention have no feeling of pressure even when worn for a long time, can always press a predetermined position of the metatarsal bone, have a toe extension function, a dorsiflexion function, and a hallux valgus Can be effectively corrected. Moreover, it has an excellent fall prevention function, can improve the balance of the foot, and can improve the exercise function.
