[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to solve such a conventional problem, that is, to provide a footwear having a fatigue recovery effect by partially attaching a semiconductor thin film-coated ceramic.

[0005]

In order to solve the above-mentioned problems, a semiconductor thin film-coated ceramic is formed by contacting at least one of a foot contact portion of a sole (a contact portion of a shoe sole with a sole), more preferably a heel, an arch, and a ball portion. This is achieved by installing

In the present invention, footwear refers to shoes, sandals, slippers, and the like, and includes footwear members such as insoles.

The semiconductor thin film-coated ceramic used in the present invention refers to a ceramic having a semiconductor thin film having a thickness of 10 μm or less on the surface of the ceramic. For example, on the surface of a titanium oxide sintered body, boron (B) -doped silicon (Si) or aluminum (Al) -doped S
A material on which so-called amorphous silicon (a-Si) such as a P-type semiconductor thin film such as i or an N-type semiconductor thin film such as arsenic (As) -Si is used. From the viewpoint of safety for living bodies, a P-type semiconductor thin film using a-Si doped with a periodic group B such as B or Al is preferable.

Attached portions of the semiconductor thin film-coated ceramic include a foot contact portion on the upper surface of the footwear, a lower portion of each finger of the sole, a sole of the sole of the foot (ball) and an outermost finger (a portion corresponding to the little finger of the hand). ) May be any triangular portion (including the arch) surrounding the sole of the base and the heel, that is, the sole portion of the footwear where the sole contacts. In other parts, the effect of reducing fatigue does not appear. Further, when the ball is placed on at least one of the heel, the arch and the ball portion, the effect of reducing fatigue is great.

The shape and size of the ceramics coated with a semiconductor thin film of the present invention are not limited, but if the size exceeds a circle having a diameter of 1 cm, the feeling of discomfort in the soles will impair the comfort.

Usually, polyurethane, rubber, leather, non-woven fabric, woven fabric and the like are used as the material of the upper surface of the footwear. In the present invention, the semiconductor thin film-coated ceramic is attached to a part of the material. When standing, touch the sole of the foot directly or through socks, etc., and select the height, size, shape of the footwear bottom material and the semiconductor thin film coated ceramic so that there is no discomfort with these materials, if it is installed, The content does not matter.

Further, when the above-mentioned warp is provided on a part or the whole of the upper surface of the sole of the footwear other than the portion where the semiconductor thin film is coated with ceramics, a bamboo stepping effect is added and the effect is further increased.

Hereinafter, the present invention will be described specifically with reference to examples.

[0013]

[Embodiment 1] An upper base 1 is formed so as to have a structure shown in FIGS.
And the outer sole 2 was made as a bottom for sandals. The upper bottom 1 and the outer bottom 2 are made of polyurethane and each has a hardness of JI
S hardness tester (manufactured by TAKACHIHO, JIS HARDN
ESS TESTER) were 35 and 50.

Further, a ceramic manufactured by Tohoku Ricoh Co., Ltd. was used as the semiconductor thin film-coated ceramic. As shown in FIG. 3, the structure has a cylindrical conical shape in which a cone having a height of 1.0 mm is placed on a cylinder having a diameter d of 5.5 mm and a height a of 1.3 mm. A 0.1 μm P-type semiconductor thin film of B-doped Si is formed on the surface of the part by sputtering.

Further, an aluminum cylindrical conical member of the same type as the ceramics coated with the semiconductor thin film was prepared for a comparative test.

The position shown in FIG. 1, that is, the ball portion 5 of the foot,
Small holes having a diameter of 6 mm and a depth of 2 mm were made in three places, that is, the arch 6 and the heel portion 7, and 10 upper soles for the right foot were prototyped. Similarly, ten right soles and left and right symmetrical upper soles were prepared for the left leg, and a total of ten pairs of sandal soles were prototyped.

At the bottom of each of the small holes, a cushion material 10 made of polyurethane and having a thickness of 1 mm and a JIS hardness of 25 with an adhesive applied to both upper and lower surfaces is provided. When a cylindrical conical member was attached, the head became about 1 mm.

Next, using the upper bottom and the outer bottom, an upper part 11 is attached as shown in FIG.
I made my feet.

Among them, a prototype A having the above-mentioned P-type semiconductor thin film-coated ceramics of the present invention attached to all small holes (three per foot) was mounted on five feet. For the remaining five feet, the aluminum cylinder conical member for comparison was attached to all the small holes for comparison, and was used as prototype B.

Each of the above prototypes A and B is used for the left and right
0 people walked for 5 km each and worn for 8 hours including office work in a sitting position and evaluated. That is, five people wore the prototype A on the right foot and the prototype B on the left foot, and the other five wore the prototype A on the left foot and the prototype B on the right foot and tested. In addition, all the members put on socks and performed a wearing test. As a result of the test, seven persons wearing the prototype A had less fatigue (especially stiffness on the arch) than the feet wearing the prototype B, and the remaining three persons felt fatigue on the left and right. No difference was found in the results, and it was found that the ceramics coated with the semiconductor thin film had an effect of reducing fatigue.

Next, the left and right sides were exchanged, and a second confirmation test was performed. That is, five people who first wear the prototype A on the right foot wear the prototype A on the left foot and the prototype B on the right foot, and the other five perform the above-mentioned 8-hour wear test in reverse.
Prototype A is less fatigued than prototype B
There was no difference between the left and right people. That is, the fatigue recovery effect of the ceramics coated with the semiconductor thin film was confirmed.

[0022]

Example 2 A semiconductor thin-film-coated ceramic and an aluminum cylindrical conical member were attached only to the heel portion, removed from the ball portion and the arch, and a semiconductor thin-film-coated ceramic mounted product was prototype C, an aluminum cylinder for comparison. Prototype D was used for mounting the conical member,
When exactly the same test as in Example 1 was performed, the first time and the second time, the foot wearing the prototype C by eight people,
The result is less fatigue than the foot wearing prototype D,
The rest showed no difference between left and right. That is, 8
0% of the persons recognized the fatigue recovery effect of the semiconductor thin film-coated ceramics.

[0023]

Embodiment 3 A semiconductor thin-film-coated ceramic and an aluminum cylindrical conical member are attached only to the ball portion, removed from the heel and the arch, and a semiconductor thin-film-coated ceramic mounted product is a prototype E, an aluminum cylinder for comparison. Exactly the same test as in Example 2 was conducted except that the conical-shaped member-attached product was the prototype F. As a result, the first time, 7 persons, and the second time, 8 persons wore the prototype E,
The result is less fatigue than the foot wearing prototype F,
The rest showed no difference between left and right.

[0024]

Embodiment 4 A semiconductor thin film-coated ceramic and an aluminum cylindrical conical member are attached only to the arch and are removed from the ball portion and the heel portion. Exactly the same test as in Example 2 was carried out except that the cylindrical cone-shaped member-attached product was prototype H. The first time, 6 people, and the second time 7 people wore the prototype G,
The result is less fatigue than feet wearing prototype H,
The rest showed no difference between left and right.

[0025]

Fifth Embodiment Instead of making a small hole in the portion set in Example 1, small holes are made in two places, the back of the thumb at the upper bottom and the back of the outermost finger (the finger corresponding to the little finger). In the same manner as in Example 1, a prototype I of two semiconductor thin film-coated ceramics was attached, and a prototype J of an aluminum cylinder conical member attached for comparison was made as a prototype J. Five trials of I and J were made. The same test as in Example 1 was performed. As a result, in the first time, five persons felt that I was not more tired, and five persons had no difference between left and right, and the second time had exactly the same result, and the result was slightly less effective than in Examples 1 to 4. However, the effect was still remarkable.

[0026]

[Comparative Example 1] A prototype M was prepared by removing all the semiconductor thin film-coated ceramics from the five test samples of the semiconductor thin film-coated ceramics of Example 1 and leaving small holes. A test similar to the first test of Example 1 was conducted by 10 persons using the prototype M5 feet and the prototype B of Example 1 (a comparative product having a cylindrical aluminum conical member attached thereto). As a result, two persons were less likely to be tired of prototype B, and eight persons had no difference between right and left. That is, 20% recognized the effect of the aluminum cylinder conical member for comparison. Whether this effect is due to the bamboo stepping effect of the cylindrical conical member or the psychological effect before wearing is considered. Not obvious.
The effect of this degree may affect the first to fifth embodiments as an error.

[0027]

COMPARATIVE EXAMPLE 2 Ten shoes were prototyped using the upper sole as an insole except that no small hole was formed in the upper sole, and five of the shoes were used for the sole on the back of the upper material. Prototype K was prepared by attaching a semiconductor thin film-coated ceramic with an adhesive to a portion where the instep comes into contact and a portion where the upper part of the toe was in contact, and the remaining 5 pairs were made as prototype L. In the same manner as in Example 1, the prototypes K and L were worn left and right, and one test was performed. As a result, two persons recognized the fatigue prevention effect of K, and seven persons had no difference between the left and right, and one person L resulted in less fatigue. That is, there is no effect in attaching the portion in contact with the upper part of the foot.

[0028]

According to the present invention, footwear with less wearing fatigue can be provided by installing the semiconductor thin film-coated ceramic in a portion where the sole of the footwear is in contact.

Further, if the installation portion is at least one of the heel, the arch, and the ball portion, the effect is large.
