Abstract

PROBLEM TO BE SOLVED: To provide a method to reach shoes with a structure which maintains alignment of leg bones peculiar to each person in standing and walking and restores arch shape by dispersing sole pressure, and to provide to each person sole plates which realize such shoes and shoes which retard wearing at outer fringes behind heels. SOLUTION: An insole surface including heel and toe parts forms an inclined plane with an angle that makes the heel part higher than the horizontal plane by a height of shoe heel. Therefore, a foot-printer, or the like, is placed on an inclined surface of the same tilt angle with the inclined plane of the shoe to be put on, sole pressure distribution and arch shapes of a person when putting on the shoes are examined, insole plates are inserted into sole portions where the sole pressure is weak and the arch is disappeared, and the sole pressure dispersion and the arch shapes are designed to be restored. In this way the leg bone alignment is maintained, the shoes do not charge overload to movement organs of legs and facilitate to walk with little tendency to be tired. At the outer fringes behind the heels, which are formed with non-metallic materials and easy to be worn away, by embedding many thin metallic rods and combining non-metallic and metallic materials, progress of wearing at the outer fringes behind the heels can be retarded.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention examines the distribution of sole pressure, the shape of a vertical arch, and the shape of a horizontal arch on an inclined surface of a shoe worn by each person, and finds a hip joint, a knee joint, and a thigh joint for standing and walking. The lower limb bones can be kept aligned without forcing excessive adduction, abduction, varus and varus of the subtalar joint, and the sole pressure can be reduced by the calcaneus, thumb ball, and toe ball A method of deriving the most suitable walking shoes for the wearer by dispersing the vertical arches and horizontal arches that are dispersed evenly in the part. And, it relates to the wear resistance of the sole plate and the heel that realizes it.

[0002]

2. Description of the Related Art Conventionally, changing the distribution of unbalanced sole pressure on standing and walking shoes and the alignment of the lower limb bones specific to the wearer are difficult to walk because the feet do not have a feeling of fitting. It tends to cause stress accumulation and orthopedic disease. Therefore, a sole plate such as an insole or an insole is inserted into the sole to be worn to disperse the sole pressure and recover the shape of the vertical arch and the horizontal arch. Also, against intentional abrasion occurring at the outer edge of the heel, the heel is prevented from being worn by providing studs, metal fittings, ceramics and the like on the heel grounding surface. Previously, a horseshoe-shaped metal plate was driven into the outer edge of the heel to reinforce the worn part, but it was easy to slip on tiles and metal surfaces, and currently horseshoe-shaped metal plates are not used,
It is common to replace worn heels.

[0003]

[Problems to be Solved by the Invention] Each person has his or her own unique alignment of lower limb bones, distribution of plantar pressure applied to the ground contact surface, shape of vertical arch and horizontal arch, etc. Has important work. The sole pressure is the load on the sole that is ideally applied to the ball of the toe, the ball of the toe, and the calcaneus, and the vertical and horizontal arches receive the applied load as a cushion. It is important to maintain the shape of the arch. The shoes that maintain the alignment of the lower limb bone unique to the person for standing and walking, disperse the sole pressure and maintain the shape of the arch, are the most suitable for the wearer, easy to walk and fit to the foot, Shoes that do not impair the motor function of the lower limbs. The alignment of the lower limbs, the distribution of sole pressure, and the shape of the arch are inseparable, but the distribution of sole pressure was examined on the horizontal plane, and the foot was examined on the inclined plane of the sole, which was higher by the heel, on the horizontal plane. An insole or an insole corresponding to the part where the sole pressure is weak is applied to distribute the sole pressure. A sole plate is applied to the part where the arch disappeared to restore the elasticity of the sole in the same manner. However, the distribution of the sole pressure measured on the horizontal plane is O-leg, X
In order to have the alignment of the lower limb bone specific to the person such as leg, varus, valgus, etc.
It cannot be applied to a sole with a slope as it is. The distribution of the sole pressure and the shape of the arch differ between the horizontal plane and the inclined plane, and based on the distribution of the sole pressure on the horizontal plane and the shape of the arch, the distribution of the sole pressure on the inclined plane is averaged over the calcaneus. However, there is a problem that the shape of the arch cannot be recovered by dispersing the ball into the ball of the toe and the ball of the little toe, and the alignment of the lower limb bones is changed.

[0004] The first heel contact with the heel for standing and walking is performed at the outer edge of the heel, and the heel of a shoe made of a material such as synthetic rubber inevitably wears the outer edge of the heel, and the sole pressure of the wearer is increased. Distribution is biased, and the alignment of the lower limb bones changes. Therefore, in order to disperse the sole pressure and maintain the alignment of the lower limb bones, there is a problem in that wear of the outer edge of the heel rear must be suppressed.

[0005] Except for specially-designed shoes used for sports, mountain climbing, etc., shoes used in daily life that are easy to walk, have a fit to the feet, and do not impair the motor function of the lower limb are defined as hip and knee joints. Do not force the joints, thigh joints, and subtalar joints to overload or move in one direction, maintain the alignment of the lower limb bones specific to each person, and at the same time, average the sole pressure and the heel bone and the ball of the thumb It is a shoe with a structure that disperses to the little toe ball. Therefore, it is an object of the present invention to obtain a sole plate which is a shoe having a structure most suitable for each person, and a heel which is hard to wear to maintain the structure.

[0006]

[Means for Solving the Problems] Maintaining the alignment of the lower limb bone unique to the person during standing and walking, and distributing the distribution of the sole pressure applied to the sole to the calcaneus, the toe ball, and the toe ball The footprinter installed on the inclined surface with the same inclination angle as the shoes worn by the person, not the horizontal distribution of the sole pressure distribution and the shape of the arch to recover the shape of the vertical arch and the horizontal arch Then, a load is applied to the sole to examine the distribution of the sole pressure, the shape of the vertical arch, and the shape of the horizontal arch. Then, a crescent-shaped wedge-shaped thickness of several m is applied locally to the sole with weak sole pressure.
The elasticity of m is stuck and the dispersion of the sole pressure is checked again by a foot printer or the like installed at the same inclined position as the shoes, and the thickness of the sole plate is adjusted. The weak part of the sole pressure at the calcaneus appears inside or outside the calcaneus, inside the left and right calcaneus,
A crescent-shaped wedge-shaped sole plate that fits on the outside, a weak part of the sole pressure appears on the inside in the toe ball part, and on the outside in the toe ball part, the right and left toe ball part, the left and right toe ball part A crescent-shaped wedge-shaped sole plate that fits both is applied to the weak part.
A large convex sole is applied to the part where the vertical arch has disappeared, and a small convex sole is applied to the part where the horizontal arch has disappeared.
Recover the shape of vertical and horizontal arches. However, in the case of arches, it is difficult to derive the appropriate size of the foot plates for vertical and horizontal arches by a simple inspection method, and in fact, it is necessary to select one that fits various foot plates for vertical and horizontal arches. . These sole plates can reinforce the part where the arch has disappeared due to weak sole pressure, do not change the specific alignment of the lower limb bone, maintain the distribution of the sole pressure and alignment of the lower limb bone, and walk Lower limb joints, muscles,
It is a shoe that fits the foot and is easy to walk without putting an excessive burden on the musculature such as bones.

[0007] The heel contact of walking is performed at the outer edge of the back of the heel, and from the alignment of the lower limb bones specific to each person, the lower limb in which the O leg and the lower leg are curved outward,
In the X-leg, abrasion occurs in the rear portion of the heel, generally in the outer side of the heel, and as the alignment of the lower limb bones of the O-leg and the X-leg becomes more remarkable, the abrasion of the outer side of the heel and the rear portion is remarkable. Therefore, the wearer of the worn heel shoes changes the alignment of the lower limb bones, causing a bias in the distribution of the sole pressure. Therefore, in order to suppress the wear of the outer edge of the heel, use a metal fitting with a number of wear-resistant metal bars on a horseshoe-shaped metal plate, exposing the metal plate side to the shoe sole and the metal bar side to the heel contact surface. And embed it in the outer edge of the heel rear. By dispersing metal bars with different wear properties in the heel made of a material such as synthetic rubber, the wear resistance is improved compared to the heel wear that occurs with a single material, and the metal plate sinks. It prevents intrusion.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention disperses and eliminates plantar pressure applied to a calcaneus, a toe ball, and a toe ball on average without destroying the alignment of lower limb bones inherent to each person. By applying the sole plate to the sole to recover the arch that is running, the mechanical load on the lower limbs of standing and walking, especially the unnatural load on the foot, is removed, and the foot is not overloaded. Shoes that fit easily into the feet. In addition, abrasion occurs at the outer edge of the heel where the heel first comes into contact with the heel during the stance phase of walking, thereby breaking the maintained alignment of the lower limb bone and biasing the dispersed sole pressure. Wear is inevitably caused on the outer edge of the heel, and this wear must be suppressed. A number of metal rods of several mm in diameter are placed on a horseshoe-shaped thin metal plate corresponding to the shape of the outer edge of the heel. Is embedded in the outer edge of the heel to suppress the progress of wear.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. The sole pressure of the wearer's right foot was investigated on a footprinter located on the same slope as the wearer's shoes. FIG. From Fig. 1 calcaneus (3) medial, thumb ball (1)
It can be seen that the sole pressure is strong, and the outside of the calcaneus part (3) and the little toe ball part (2) have a weak shade and are part of the sole pressure reduction (4). The vertical and horizontal arches are normal. Therefore, using a material such as silicon or rubber, the maximum front and rear diameter is 60 mm, and the maximum left and right diameter is 1 mm.
The outer side (7) of a crescent-shaped plantar plate (6) having a thickness of 6 mm and an outer thickness of 2 mm is placed outside the sole pressure-reducing portion (4) of the calcaneus (3), and the inside (8). Point inward. FIG. Similarly, the maximum front and rear diameter is 75 mm, and the maximum left and right diameter is 30 m.

Point inward. FIG. Then, the distribution of the plantar pressure was examined again on the foot printer, and the average distribution of the plantar pressure to the calcaneus (3), the ball of the thumb (1), and the ball of the toe (2) was determined from FIG. Is seen. The shape, thickness, and size of these sole plates (5) and (6) make it easy for the wearer of this shoe to place a load on the exerciser of the lower limb, and it is easy to walk and fit to the foot. The shape and size of the sole plate (6) applied to the calcaneus part (3) can be applied to the inside and outside of the calcaneus part (3), and the sole plate (5) applied to the toe ball part (2) The shape and size of ()) can be applied to the ball part of the toe (1), but the thickness of the sole plates (5) and (6) must be different depending on the strength of the sole pressure.
A stainless steel rod (10) having a diameter of 2 mm and a length of 14 mm is mounted on a horseshoe-shaped stainless steel plate (4 mm in width and 2 mm in thickness), and the stainless steel plate (13) is heeled (9).

[0010]

According to the present invention, the distribution of the sole pressure of the wearer is examined on the inclined surface of the sole formed by the horizontal plane of the shoe to be worn, and the sole pressure of the calcaneus, the toe ball, and the toe ball are measured. By reinforcing the attenuation part, aiming for the average dispersion of the sole pressure, and making the arch of the structure that aims to recover the arch of the disappearing part of the vertical arch and the horizontal arch,
It is a shoe that fits a foot that is easy for the wearer to walk and does not get tired when standing on the ground and does not place an excessive burden on the locomotor of the lower limb of walking.

The large convex sole plate applied to the disappearing portion of the vertical arch and the small convex sole plate applied to the disappearing portion of the horizontal arch act as a cushion for the lost arch,
Restores the shape of the arch. However, the most common abnormality in sole motor function is the uneven distribution of sole pressure, which is a constant crescent-shaped wedge-shaped calcaneus, thumb, and small toe By fixing the two types of sole plates corresponding to the calcaneus, the toe ball and the toe ball to the sole in the shape and size of the sole, the sole pressure is increased by the calcaneus and the toe ball. It can be dispersed on the small toe ball part on average.

[0012] By embedding a large number of thin metal rods having a diameter of several millimeters on a horseshoe-shaped metal plate in a heel rear outer edge formed of a nonmetallic material, it is possible to suppress the progress of wear of the heel rear outer edge, and Dispersion of the sole pressure and the shape of the arch can be maintained. Also, since the metal bar is on the metal plate, there is no need to worry about sinking in the heel even if pressed, and since many metal bars are scattered in the non-metallic material on the heel contact surface, if the metal bar is a metal flat surface This makes the shoe less slippery when walking on metal surfaces, tiles, and ice.

[0013] The shoes are biased in the sole pressure in the standing phase of walking and walking, inversion of the knees, abduction of the knees, inversion of the feet, forced movement of the outgrowths, and movement of the lower limbs to the locomotor. It is a healthy leg-friendly shoe that prevents excessive load and prevents the occurrence of lower limb diseases such as plantar fasciitis and knee osteoarthritis caused by collapse of lower limb bone alignment.
