Abstract

[Problem] Taping has been used as an effective method for reinforcing or correcting arches. However, taping requires advanced techniques and may need to be applied too tightly or loosely, making it difficult for amateurs to apply the tape properly. In addition, the tape quickly becomes painful and is often discarded, resulting in high costs. [Solution] The above problems have been solved by a foot supporter that supports the entire foot below the ankle. [Selected Figure] Figure 1

Description

The present invention relates to a foot support, and more particularly to a foot support that supports the entire foot from the ankle down.

The arch is a depression formed from the center to the rear half of the sole of the foot, and plays an important role for humans who walk upright on two legs. The structure of the arch is briefly explained with reference to FIG. 14. The arch is supported by three arches and three support points a, b, and c. The three support points a, b, and c that form the arch are formed by the first metatarsal head a, the fifth metatarsal head b, and the medial and lateral processes c of the calcaneal eminence, and each support point a, b, and c supports two adjacent arches.

The anterior arch stretched between the anterior supports a and b is the shortest and lowest, the lateral arch of medium length and height is between the lateral supports b and c, and the medial arch of longest and highest is between the medial supports a and c.

The shape of the arch of the foot is like a sail inflated by the wind, and since its apex is shifted backward, the weight is placed on point c on the rear slope at the center of the dorsum of the foot. The arch of the foot facilitates posture control in the forward/backward, left/right, and horizontal rotation directions, and plays an important role in upright bipedal walking, such as absorbing the impact of landing when walking, protecting the foot, and dissipating heat.

The three arches mentioned above are actually supported by the integral functioning of the bones, joints, ligaments, muscles and tendons of the sole. If these bones, joints, ligaments, muscles and tendons are underdeveloped and the arch is not fully formed, or if these bones, joints, ligaments, muscles and tendons are damaged or weakened for some reason and the arch collapses, various inconvenient symptoms will appear. For example, hallux valgus, Morton's disease, plantar fasciitis, heel spurs, osteoarthritis of the knee, bow legs, etc. In order to improve such inconvenient symptoms, it is necessary to reinforce or correct the arch.

Traditionally, taping has been used as an effective method for reinforcing or correcting the arch. However, taping requires advanced techniques and may need to be applied too tightly or loosely, making it difficult for amateurs to perform the treatment properly. In addition, the tape quickly becomes painful and is often discarded, which makes it expensive.

In order to solve the above problems, various ankle joint supports have been proposed in the past, including supports proposed for the purpose of correcting the bones and joints around the ankle by appropriately fixing the bones, joints, and muscles around the ankle (for example, Patent Document 1), supports proposed for the purpose of correcting the habit of walking with the legs turned in or turned out, and posture, which have become part of daily life, by fixing the ankle, ankle, and toes in a way that makes it easier to move them back and forth under no load (for example, Patent Document 2), and supports proposed for the purpose of preventing heel eversion and inversion with a simple structure, as an ankle attachment device that goes around the back of the foot and the sole with an elastic belt and goes around the heel and is attached to the ankle (for example, Patent Document 3).

The above-mentioned Patent Document 1 discloses an elastic heel-ankle supporter that can be worn on the human foot, which includes a tubular supporter that can cover the surface of the area from the instep to the sole, heel and ankle, and a belt-type supporter that can be attached to the tubular supporter and worn on the foot from above the tubular supporter, but has a problem that it is a double structure and requires a lot of effort to put on and take off.In addition, the tubular supporter abuts on the heel side of the transverse arch and does not directly protect the transverse arch, and is shaped with the tip of the sock removed, which raises the concern that the entire abutment area between the tubular supporter and the foot will be compressed.In addition, the transverse arch sole support part, the transverse arch first metatarsal side support part and the transverse arch fifth metatarsal side support part, which have the function of applying pressure to the first and fifth metatarsals acting on the transverse arch to reinforce the deflection of the transverse arch, and the transverse arch sole support part, which have the function of applying pressure to the first and fifth metatarsals acting on the transverse arch to reinforce the deflection of the transverse arch, and the transverse arch sole support part, which have the function of applying pressure to the outer longitudinal arch and the medial longitudinal arch to reinforce the deflection of the medial longitudinal arch and the outer longitudinal arch, In addition to the medial longitudinal arch support part, lateral longitudinal arch support part, and medial longitudinal arch sole support part and lateral longitudinal arch sole support part, which have the function of reinforcing the above-mentioned arches, the heel lock sole first metatarsal side support part, heel lock sole fifth metatarsal side support part, and heel lock first metatarsal side support part, heel lock fifth metatarsal side support part, which have the function of pinching the heel, crossing it near the center of the Achilles key and pulling it upward, do not have any support parts that reinforce the deflection of the three arches, so there is also the problem that the effect of absorbing impact from the ground cannot be expected.

In addition, the orthosis described in Patent Document 2 is a corrective supporter that is attached to the ankle, ankle, and toes to properly correct inward walking, outward walking, and posture, and is made up of three members, an ankle strap, a sole strap, and a toe strap, and is fixed to the ankle, ankle, and toes with a hook-and-loop fastener in an unloaded state, but since it does not have a heel lock first metatarsal support part and a heel lock fifth metatarsal support part that have the function of sandwiching the heel and crossing it near the center of the Achilles tendon to pull it upward, it does not reduce the twisting of the Achilles tendon and the burden on the triceps surae that forms the Achilles tendon, and it is difficult to stabilize the entire lower leg. In addition, the hook-and-loop fastener attached to both ends of the toe strap has a thickness at the overlapping part of the male and female surfaces, and when the joint surface is placed on the sole of the foot, it causes discomfort and discomfort, and even if it is wrapped around the back of the foot, shoes and socks get caught and are difficult to put on, so it does not feel practical and it is troublesome to put on.

Furthermore, Patent Document 3 discloses an ankle-fixing elastic belt that is a simple ankle-worn device that is attached to the ankle, has an ankle-wrapping part, a heel-wrapping part, and a foot-dorsal-plantar-wrapping part, and suppresses heel inversion and eversion while improving sports performance. However, the device does not directly protect the transverse arch, and does not have a transverse arch sole support part, a transverse arch first metatarsal side support part, and a transverse arch fifth metatarsal left support part that act on the transverse arch to apply pressure to the first and fifth metatarsals to reinforce the deflection of the transverse arch, so the formation of the transverse arch cannot be reinforced, and the load transfer to the fingertips is difficult to transmit firmly, making it difficult to reduce the burden on the lower limbs. In addition, the device is attached by connecting both ends of a single elastic belt using hook-and-loop fasteners, buckles, hooks, etc., but the attachment process has the problem that it is difficult for elderly people to set the tension and crossing position.

Furthermore, as in claim 4, when the intersecting bands of the central sole contact portion are fixed to each other, the position of the support portion arranged at the front is fixed, thereby ensuring reliable support, and further, there is an effect of improving the feeling of pressure near the arch of the foot, which is the set position.
In addition, as in claim 5, at the intersection where both ends of the transverse arch plantar support part intersect in an eight-shaped loop, and at the intersection where the ends of the heel lock first metatarsal side support part and the heel lock fifth metatarsal side support part intersect, a retaining part is formed to hold each band. As a means for providing width to the setting position of the intersection, an elastic material is used for the retaining part, which can accommodate differences in the setting position of the intersection part due to differences in the shape of the foot, and has the effect of making it easy for each wearer to set it to the optimal position they prefer.
Furthermore, as in claim 6, when the retaining portion is formed on the surface of the overlapping inner band at each intersection, each intersection is less likely to shift and is easier to set, which has the effect of preventing the retaining portion from coming into direct contact with the skin and causing discomfort or a sense of unease.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS.

The foot supporter 1 is made up of a transverse arch D at the bottom connecting the tip of the first metatarsal A and the tip of the fifth metatarsal B of the foot, which is wound around the transverse arch D at the bottom, and supports the transverse arch D; a transverse arch first metatarsal side support part 3 and a transverse arch fifth metatarsal side support part 4, which are wound around the dorsum of the foot K from both ends of the transverse arch sole support part 2 in a crossed loop shape in the form of an eight, and support the first metatarsal side and the fifth metatarsal side of the transverse arch; a medial longitudinal arch support part 6 and an lateral longitudinal arch support part 7, which cross at a dorsum of the foot abutment part 5 abutting the dorsum of the foot K, and which extend from the dorsum of the foot abutment part 5 to support the medial longitudinal arch E and the lateral longitudinal arch F; a medial longitudinal arch sole support part 8 and an lateral longitudinal arch sole support part 9, which are formed by extending from the medial longitudinal arch support part 6 and the lateral longitudinal arch support part 7; The support member is provided with a sole center contact portion 10 extending from the port portion 9, intersecting near the sole center G and contacting the sole, a heel lock sole first metatarsal side support portion 12 and a heel lock sole fifth metatarsal side support portion 13 extending outward from the sole center contact portion 10 and intersecting at a heel upper crossing portion 11 above the heel, thereby supporting the heel lock sole first metatarsal side and the heel lock sole fifth metatarsal side formed on the sole, a heel lock first metatarsal side support portion 14 and a heel lock fifth metatarsal side support portion 15 formed below the heel upper crossing portion 11 and supporting the calcaneus H in a surrounding manner, and a distal tibiofibular joint support portion 17 extending from the heel upper crossing portion 11 and surrounding the ankle at a position above a line connecting the medial malleolus I and the lateral malleolus J, the ends of which are connected to each other by a connecting means 16 to support the distal tibiofibular joint L.

The elastic band 18 is sewn in a cross shape to the sole center contact portion 10, but it may be left unsewn to allow it to move freely. If sewn, it has the effect of providing a feeling of pressure on the arch of the foot and improving stability. Since the foot supporter 1 is divided into the toe side and the heel side by the sole center contact portion 10, it is possible to use bands with different specifications for the toe side and the heel side, and it is also possible to use a belt that does not have elasticity. In addition, it is possible to strengthen the fixation of the ankle by increasing the strength of the belt on the heel side compared to the toe side, or conversely, it is also possible to weaken it, so that it can be specified according to the user. In addition, if it is not sewn, since there is no fixation at the sole center contact portion 10, the foot supporter 1 has the effect of reinforcing the deflection of the three arches, improving the lifting force, and adjusting the strength to the desired level.

As shown in Fig. 1, the foot supporter 1 is made of one elastic band 18. On the plane of the back surface of the elastic band 18, a hook-and-loop fastener (female) 16a and a hook-and-loop fastener (male) 16b are provided at both ends as the connecting means 16. The foot supporter 1 is provided with a first anti-slip means 19 on the inside of the transverse arch sole support part 2, a second anti-slip means 20 on the inside of the heel lock first metatarsal side support part 14, and a third anti-slip means 21 on the inside of the heel lock fifth metatarsal side support part 15. The first anti-slip means 19 is provided near the center of the elastic band 18, and the second anti-slip means 20 and the third anti-slip means 21 are provided at equal intervals on both sides of the first anti-slip means 19. A first holding part 22 that holds each of the elastic bands 18 is formed at the dorsum of the foot abutment part 5 that crosses in a figure-8 loop from both ends of the transverse arch plantar support part 2, and a second holding part 23 that holds each of the elastic bands 18 is formed at the heel upper crossing part 11 where the ends of the heel lock first metatarsal side support part 14 and the heel lock fifth metatarsal side support part 15 cross each other. When worn on the right foot, the foot supporter 1 is integrally formed so as to support the entire foot from the ankle down with a single elastic band 18 that has elasticity.

The elastic band 18 forming the foot support 1 is available in four sizes, S, M, L, and LL, with lengths set between 890 mm and 1080 mm, but the length can be adjusted to SS or 3L depending on the foot size, either short or long, and the width is preferably within the allowable range of 25 mm to 60 mm to provide a sense of stability. The material of the elastic band 18 is preferably one that has a stretch rate of about twice as much and can flexibly accommodate the movement of the foot.

As shown in FIG. 2, on the plane of the surface of the elastic band 18, the first retaining portion 22 provided between the first anti-slip means 19 and the third anti-slip means 21 provided near the center of the transverse arch plantar support portion 2 is inclined obliquely toward the first anti-slip means 19, and both ends are fixed by sewing with thread, and the non-sewn portion is left floating. This makes it easy to understand the setting position of the dorsum of the foot contact portion 5, where both ends of the transverse arch plantar support portion 2 are wrapped from the plantar portion C to the dorsum of the foot K and crossed at the dorsum of the foot contact portion 5, when the foot supporter 1 is worn, and when the adhesive hook-and-loop fastener (female) 16a sewn to one end of the elastic band 18 is passed through the first retaining portion 22, the length of the first retaining portion 22 is longer than the width of the foot supporter 1 and is set obliquely, so that the range of adjustment of the setting position by the angle of the elastic band 18 crossing at the dorsum of the foot contact portion 5 is wide, and it can be adapted to the shape and size of the foot.
The second retaining portion 23 provided between the second anti-slip means 20 and the adhesive hook-and-loop fastener (female) 16a provided at one end of the elastic band 18 is inclined diagonally toward the adhesive hook-and-loop fastener (female) 16a and, similar to the first retaining portion 22, both ends are fixed by sewing with thread, the portion not sewn is left floating, and the adhesive hook-and-loop fastener (male) 16b sewn to the other end of the elastic band 18 is passed through the second retaining portion 23.
It is also preferable that the length of the first holding portion 22 is about 70 mm to 90 mm, and the length of the second holding portion 23 is about 40 mm to 60 mm. As for the material, elastic rubber allows the width of the crossing angle to be set wider, but non-elastic tape, woven label, or ribbon may also be used.

As shown in FIG. 3, on the plane of the back surface of the elastic band 18, the first anti-slip means 19 is installed near the center of the transverse arch sole support part 2, the second anti-slip means 20 is installed on the adhesive part hook-and-loop fastener (female) 16a side, and the third anti-slip means 21 is installed on the adhesive part hook-and-loop fastener (male) 16b side by sewing, respectively. The anti-slip means are circular in shape and are joined by sewing with thread, but shapes include oval, square, rectangular, polygonal, star, heart, etc. Also, the joining means can be adhesive. The anti-slip means can be polyester fiber, polyester resin, nylon, etc., but can also be printed. The first anti-slip means 19, the second anti-slip means 20, and the third anti-slip means 21 are sewn in consideration of the durability of the material that is gentle on the skin, but silicone rubber can also be welded.

As shown in Figure 4, the transverse arch plantar support part 2, which supports the transverse arch D of the plantar part C connecting the tip of the first metatarsal bone A and the tip of the fifth metatarsal bone B of the left foot, is formed so that both ends are wrapped around the dorsum of the foot K.
