Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to footwear for walking, and more particularly to footwear for walking which is used to correct the posture of legs during walking.

[0002]

2. Description of the Related Art Generally, many elderly people complain of knee pain during walking. Most of the causes are due to a joint disease called osteoarthritis of the knee.

This osteoarthritis of the knee is a symptom in which the cartilage in the knee joint is worn away due to overuse of the knee, and the bones of the knee come into direct contact with each other to cause pain. It tends to occur when the posture is bad and the weight acts on a specific part of the knee.

For example, in the case of an O-legged person, most of the weight is supported by the inner side of the knee during walking, so that only the cartilage inside the knee is easily worn away, and the above-mentioned diseases occur. Many are seen.

An example of dealing with such a disease from the viewpoint of the structure of footwear is shown in Japanese Utility Model Publication No. 4-50803.

In this technique, a portion of the bottom of the footwear corresponding to the outside of the foot to be inserted therein is formed higher than a portion corresponding to the inside of the foot.
By moving the position of the knee inward to correct the posture of the leg, the weight support position in the knee is moved to the outside of the knee,
In this way, the contact position between the bones of the knee is shifted from the inner side where the cartilage is worn to the outer side where the cartilage is not worn.

[0007]

With the advent of such conventional footwear, it is possible to reduce the pain of the knee during walking. However, the conventional footwear also has the following improvements. There are some problems to be solved.

That is, in the above-mentioned footwear, the knee is forcibly moved inward by the inclination of the bottom of the footwear when walking, but the height of the heel is about 20 m.
If it is more than m, there is a problem that the foot moves inward or forward in the footwear along the inclination and is pressed against the side or front part of the footwear.

Such a problem not only hinders walking, but also causes an unnecessary load to be applied to the side portion and the front portion of the footwear, which have relatively low strength, to deform the footwear. .

The present invention has been made in view of the above-mentioned conventional problems, and corrects the posture of the leg during walking,
It is a problem to be solved to provide footwear for walking which can prevent unnecessary movement of the foot in footwear.

[0011]

In order to solve the above-mentioned problems, the walking footwear according to claim 1 of the present invention is formed so that the outside of the bottom is inclined so that the outside is higher than the inside. The footwear has a structure in which a thick portion is formed in a portion where the base of the big toe to be inserted is located.

According to a second aspect of the present invention, the footwear for walking has a structure in which the inclined portion and the thick portion in the first aspect are formed on a bottom member which constitutes the footwear.

Further, the walking footwear according to claim 3 of the present invention is characterized in that the slope and the thick portion in claim 1 are:
It is formed on the insole that is inserted into the footwear.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes
1 shows a shoe as footwear according to the present embodiment.
Shows a left foot in the illustrated example, and is a space in which a shoe sole 2 as a bottom member and an upper part of the shoe sole 2 are integrally attached and the foot is inserted between the shoe sole 2. It is composed of a covering material 3 forming a part G and an insole 4 inserted into the space part G and placed on the sole 2.

Explaining these details, the shoe sole 2 is made of a hard urethane resin or the like, and a heel portion 2a is formed at one end portion in the length direction, and the heel portion is formed. A substantially flat step portion 2b is continuously provided from 2a toward the other end.

In the present embodiment, the upper surface of the shoe sole 2 is generally inward, that is, the side portion along the big toe side of the foot is lowered as shown in FIGS. 2 and 3. It is tilted.

The insole 4 is, in this embodiment,
Shoe 1 to be inserted, which is made of foaming urethane resin, etc. that is medium-hard, durable, and has little compression strain
As shown in FIGS. 4 to 6, the portion located outside of the inner wall of the insole 4 has a slanted outer thick wall that gradually becomes thicker from a substantially middle portion in the width direction of the insole 4 toward the outer end portion. The portion 4a is formed over almost the entire length, and at the position where the base of the big toe placed on the insole 4 is opposed, as shown in FIG. 4, FIG. 5 and FIG. An inner thick portion 4b is formed which gradually becomes thicker toward the inner side edge.

Therefore, when the insole 4 is inserted into the space G of the shoe 1 and placed along the upper surface of the shoe sole 2, it acts synergistically with the inclination of the shoe sole 2. As shown in FIG. 8, at a portion other than the tip end portion of the insole 4, a height line outside thereof (curve A in FIG.
Is the inner height line (curve B in the figure).
), And the relationship is reversed near the tip to form a curved surface such that the inner height line B is higher than the outer height line A. It has become.

On the other hand, when manufacturing the shoe 1 described above, since the upper surface of the shoe sole 2 is inclined as described above, the shoe making last 5 as shown in FIG. 9 is used.

As shown by the solid line in FIG. 9, in this shoe last 5, the contact surface 5a with the upper surface of the shoe sole 2 is
In addition to the slope of the upper surface of the shoe 1, the side surface of the shoe 1 located outside is slightly swollen as compared to the conventional shoe last 6 shown by the chain line in FIG.

The shoe 1 of the present embodiment having the above-described structure
Is used with the insole 4 inserted in the space G of the shoe 1, but when walking or landing, the foot or the inner edge of the foot is lowered due to the inclination of the sole 2 or the insole 4. The knees are fed inward and the posture of the legs is corrected by inclining so that

As a result, the support position of the weight of the knee is shifted from the inside of the diseased knee to the outside thereof, so that the pain of the knee is suppressed.

When the foot is inserted into the shoe 1, the thick inner part 4b formed at the tip of the insole 4 is engaged with the base of the big toe, so that As described above, even if the foot is inclined along the inclination, the foot is prevented from moving inward or forward of the shoe 1 along the inclination.

As a result, the foot is prevented from unnecessarily moving inside the shoe 1 during walking, and the foot and the shoe 1 are held in a fixed positional relationship, which enables comfortable walking. At the same time, no excessive force is applied to the cloth material 3 of the shoe 1, and deformation of the shoe 1 is prevented.

The shapes, sizes, etc. of the respective constituent members shown in the above embodiment are examples, and can be variously changed based on design requirements and the like. For example, in the above-described embodiment, the configuration in which the outer thick portion 4a and the inner thick portion 4b are formed in the insole 4 to form the above-described inclination and the engaging portion with the base of the big toe is shown. But
The outer thick portion 4a and the inner thick portion 4b are attached to the shoe sole 2
It may be formed directly on the upper surface of the.

When the insole 4 is formed with the thick portions 4a and 4b as described in the above embodiment, the thick portion is changed according to the change of the disease condition of the user of the shoe 1. Since the degree of inclination can be changed by replacing the insole 4 with the parts 4a and 4b having different shapes, it is possible to easily cope with the above-mentioned changes in the condition of the disease while keeping the main body of the shoe 1 common. There are advantages.

Further, in the case where both the thick portions 4a and 4b are directly formed on the upper surface of the shoe sole 2, it is possible to change the condition of the disease while keeping the main body of the shoe 1 common as described above. Although it is difficult to deal with this, unnecessary movement due to slippage between the insole 4 and the sole 2 is prevented, and the foot and the shoe 1
It is advantageous in terms of manufacturability as well as enhancing the sense of unity with the number of parts.

Further, the heights of the outer thick portion 4a and the inner thick portion 4b described above can be appropriately changed according to the size and posture of the foot of the user of the shoe 1.

[0029]

As described above, according to the first aspect of the present invention.
According to the walking footwear according to, the bottom is inclined so that the outer side is higher than the inner side, so that the posture of the leg during walking is corrected, and the weight supporting position in the knee is changed from the inner side to the outer side with the disease. Can be controlled to reduce pain in the knee, and the thick portion engaged with the base of the big toe of the foot allows the foot to move to the inside of the footwear along the inclination of the bottom or the heel. It is possible to prevent the forward movement along the slope formed by.

As a result, it is possible to prevent the foot from moving unnecessarily with respect to the footwear during walking, to enable comfortable walking, and to prevent excessive force from acting on the cloth material of the shoe. As a result, the deformation of the shoe can be suppressed.

Further, according to the walking footwear according to claim 2 of the present invention, by forming the inclination of the bottom portion directly on the bottom member of the footwear, the footwear and the foot are brought into direct contact with each other, and the relative movement thereof is further reduced. In addition, the manufacturability of footwear can be improved by simplifying the steps of forming the slope and the thick portion in claim 1.

Further, according to the walking footwear according to claim 3 of the present invention, by forming the slope or the thick wall portion in claim 1 on the insole to be inserted into the footwear, the insole is replaced to replace the thick wall portion. It is possible to adjust the height and the degree of inclination, and as a result, it is possible to easily respond to changes in the condition of the footwear user's disease.
