Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shoe sole, and more particularly to a shoe sole capable of exhibiting an anti-slip effect in dynamic walking or running.

[0002]

2. Description of the Related Art Conventionally, various shoe soles are known in which a truncated cone, a square pole, a mountain, or a wavy projection is arranged on a sole contact surface. However, in response to the dynamic action of the foot during walking or running, a sufficient anti-slip effect could not be exerted.

In recent years, dynamic research on human walking or running has been established. In normal adult walking or running, two vertical arches on the inside and outside along the longitudinal axis of the foot, namely, the calcaneus, are used. (1) medial arch toward the head of the metatarsal, longitudinal arch from the calcaneus to the head of the fifth metatarsal, and two lateral arches in the lateral direction of the foot, ie, the first wedge bone And a second transverse arch from the head of the first metatarsal to the head of the fifth metatarsal.
It walks while absorbing the landing impact pressure caused by weight load in the horizontal arch. In the walking process, the weight load is first applied to the back of the heel while pronation (pronation) from the outside to the inside of the heel, and then gradually stepped along the back of the heel from the outside of the foot in the longitudinal direction of the foot. To the front of the ball portion of the fifth finger,
That is, the foot is supination (spination) on the back surface of the joint between the fifth metatarsal bone and the fifth base phalanx, and the first step is performed after strongly stepping on the ground.
It is moved by stepping on the ground while rolling on the back of the ball joint portion of the finger, that is, the back surface of the joint portion between the first metatarsal bone and the first base phalanx, and then warps the first base phalanx and the first distal phalanx. Walking while repeating the process of strongly grasping the ground on the back surface of the first distal phalanx (first finger) while kicking and kicking the ground with the first to fifth fingers, especially the 1.2.3 finger, It is said to be so-called "tilting walking or running". In such dynamic walking or running, pronation at the heel, spinning at the ball of the fifth finger, rolling at the tread along the ball joint, 1.2.3 at the finger. It is considered slippery during the kicking process.

In addition, the knee of a human leg is bent outward (O-leg) due to aging, the center of gravity of the body weight is located inside the knee when standing, and the weight load is concentrated outside the sole when walking. And the lowering of two vertical arches and two horizontal arches due to the deterioration of the muscles and ligaments of the feet due to aging. As it moves linearly from the outside of the heel to the outside of the toe, it loses its balance when walking, and it trips over, or the stepping part excessively spins out (overspination) and falls forward. It is said that it is easy to slip and slip.

In addition, when the weight load is further increased by the inner stomping part 02,
Prevents escaping in the F "" direction and ensures that the first finger is stomped on the ball and stably promotes kicking with the first, second and third fingers It is intended to be.

In the present invention, a quadrangular prism-shaped projection is formed by four sides such as a square or parallelogram, a trapezoid, or a band, and a substantially vertical side wall of 70 to 110 degrees hangs from each side. It means what has been done. In the present invention, if the edges of the vertices c and d, the sides of the oblique sides ca and cb, and the sides of the oblique sides da and db are formed to be slightly flat surfaces or curved surfaces, when landing at this portion, the landing can be made.

Since the sole in the embodiment of the present invention is constructed as described above, when a person with O-legs walks while wearing the shoe with the sole, in the walking step, first, the heel part is used. When landing from 03 to the rear of the stepping portion, the directional directions of the bases 111 and 111 of the matrix projection group M and the matrix projection group N cross each other, and therefore, the anti-slip direction F′− substantially orthogonal to these bases 111.111. The F 'and F''-F''lines also cross, preventing slippage in the cross direction and preventing loss of dynamic weight load, and stable landing without lateral swing or overpronation at the heel. It is possible.
Next, the dynamic weight load applied to the sole of the foot is moved from the heel portion to the back surface of the ball joint portion of the fifth finger through the portion without stepping on the outside of the foot. On the outer treading portion 01 of the center axis L of the sole of the shoe, the bottom 111 of the pair of protrusions 11.11 'is arranged in a large number so as to be directed obliquely forward with respect to the center axis L. Direction substantially orthogonal
The sliding in the F-F direction is prevented, and the dynamic weight load is obliquely forward in the outer treading portion 01 corresponding to the ball portion of the fifth finger of the foot, ie, the direction F orthogonal to the bottom 111. Attempts to deviate or over spin are prevented and rolling at the tread is promoted. Then, the dynamic weight load of the sole that reaches the back surface of the ball joint of the fifth finger is moved while rolling to the back surface of the ball joint of the first finger. Since a large number of bases 111 of a pair of protrusions 11.11 ′ adjacent to each other on the inner treading portion 02 ground contact surface of the center axis L of the shoe sole are directed obliquely forward with respect to the center axis L, the foot On the inner treading portion 02 corresponding to the ball portion of one finger, slippage in a direction F ′ ″ − F ′ ″ substantially perpendicular to the bottom 111 of the protrusion 11.11 ′ is prevented and dynamic weight is reduced. The load is prevented from falling off in the forward front direction of the inner treading portion 02 with the rolling, that is, in the direction F ′ ″ orthogonal to the base 111, and the stepping on the ball portion of the first finger is ensured. , 1st finger, 2nd
The kick with the finger and the third finger is promoted. Therefore, stable gait walking is promoted. In the embodiment, a pair of projections 11.11 '. . .
Are arranged in a row in an arc shape, so that a large number of grooves 2.2... Formed between the rows are also arranged in an arc shape, and
Also, the flexibility of the sole 0 is very good, and the gait walking is further promoted.
