Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an insole that is placed inside a shoe to instantly eliminate static electricity generated between the shoe and the human body.

[Conventional technology]

Assembling electronic parts, operating computers, etc.
In places where static electricity damage is likely to occur, some footwear have soles made of a conductive material in order to suppress static electricity generated between the soles of the footwear and the floor when walking in footwear.

[Problem that the invention attempts to solve]

However, although this footwear suppresses the generation of static electricity between the footwear and the floor, it
Static electricity generated between the soles of the feet and footwear cannot be suppressed. Rather, the static electricity generated between the soles of the feet and the footwear is more likely to flow through the human body to electronic components being assembled or computers being operated.

[Means for solving problems]

Therefore, the purpose of this invention is to instantly remove the static electricity generated between the footwear and the person wearing it.Furthermore, it can achieve the above-mentioned static electricity removal effect simply by placing it in or placing it on the footwear that is normally worn. death,
Moreover, it provides a safe insole that prevents external electricity from flowing back into the human body.

That is, the structure of this invention is to create an insole body made of fibers or other materials with conductivity or antistatic treatment, and to provide a flexible conductor connected at one end to the insole body, At least the surface of the main body that comes into contact with the human body has a resistance value slightly higher than that of the human body, and the other parts and/or this conductor have a resistance value that is less than the human body's resistance value, so that when the insole main body is placed on the sole plate of footwear, this conductor The other end is fixed to the outer surface of the footwear, and the tip is brought into contact with the floor surface on which the footwear is placed.

[Effect]

Therefore, this invention is placed on the sole plate of conventional footwear that is normally worn, and the front end of the conductor is fixed to the outer surface of the footwear with adhesive or the like, so that the conductor end comes into contact with the floor surface. When these footwear are worn, energy is added between the sole of the wearer's foot and the insole due to friction and body weight, some of which becomes heat, which becomes electrically charged when it peels off. However, because the insole body that is in contact with the sole of the human body is made conductive or has antistatic treatment, the static electricity caused by the peeling off charge is dispersed and uniformed throughout the insole, and the potential becomes smaller. grounded to the floor through a conductor connected to the

In this way, static electricity that may occur between the footwear and the human body is instantly removed.

〔Example〕

An embodiment of this invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes an insole main body, and this insole main body 1 is antistatically treated by adding an antistatic agent to superabsorbent polymer fibers 3 mixed with carbon 2 as appropriate. 4 is the bottom plate of footwear 5, 6 is this footwear 5
The outer peripheral side wall 7 is a flexible conductor having one end connected to the insole main body 1, and this conductor 7 has higher electrical conductivity than the insole main body 1. Reference numeral 8 designates an insulating cover for this conductor 7, and when the insole main body 1 is laid on the sole plate 4, the other end of this conductor 7 rises along the inner surface of the outer circumferential side wall 6, and further passes through the outer surface of the outer circumferential side wall 6 to cover the footwear 5. Once it is fixed to the heel 4a with adhesive, the tip is left free and the insulating cover 8 is peeled off to make contact with the floor surface 9. The above insole body 1 has a resistance value of 10 ⁷ to ^{10 11} Ω.
The conductor 7 has a resistance value of the human body (approximately 10 ⁶ to 10 ⁷
Ω) The following.

In this embodiment, energy due to friction and weight between the soles of the feet of the person wearing the footwear 5 and the footwear becomes static electricity and is not charged. That is, part of this energy becomes static electricity due to peeling electrification, and the other part becomes thermal energy. However, the insole main body 1 is placed on the sole plate 4 of the footwear 5, and the static electricity is generated on the surface of this insole main body 1, but this insole main body 1 is made of highly absorbent polymer fibers 3 mixed with carbon 2 and treated to prevent static electricity. As a result, the electric potential is dispersed and made uniform throughout the insole body 1, and the electric potential becomes small. Part of this electric potential is grounded to the floor surface 9 through the conductor 7, and the other part is caused by the thermal energy. It is released as the moisture in the insole body 1 evaporates. At this time, the superabsorbent fibers 3 of the insole main body 1 adsorb surrounding moisture, particularly human sweat, so that the antistatic effect is even greater and more reliable. By placing the insole body 1 on the sole plate 4 of the footwear 5 in this way, even when a person wearing the footwear 5 walks, static electricity that may be generated between the footwear 5 and the sole of the foot is instantly removed. It is intended to be removed.

In Fig. 2, 11 is carbon fiber;
A conductive fiber layer such as a metal fiber; 12 is a fiber layer coated on the upper and lower surfaces of the conductive fiber layer 11 and subjected to antistatic treatment; 13 is an insole body composed of the conductive fiber layer 11 and the fiber layer 12; , , 14 is a conductor having one end connected to the conductive fiber layer 11. This conductor 14 has flexibility and is covered with an insulating cover 15 except for the tip. The fiber layer 12 has a resistance value of 10 ⁷ to 10 ¹¹ Ω, and the conductive fiber layer 11 and the conductor 14 have a resistance value lower than this.

In this embodiment as well, the insole main body 13 is placed on the sole plate of the footwear as in the above embodiment, the conductor 14 is hung down on the outer surface of the footwear, and the front end of the conductor 14 is fixed to the outer surface of the footwear, so that the end is always in contact with the floor surface. I'll do what I do. As a result, even if static electricity is generated due to contact friction between the sole of the foot of a person wearing the footwear and the footwear, it is the fiber layer 12 of the insole body 13 that has been subjected to antistatic treatment that is in contact with the sole of the foot. Therefore, this fiber layer 12
Static electricity is dispersed and made uniform throughout, the potential becomes low, and it is grounded to the floor surface through the conductive fiber layer 11 and the conductor 14 on the lower surface of the fiber layer 12.

However, since the antistatically treated fiber layer 12 has a resistance greater than the human body's resistance value of approximately 10 ⁶ to 10 ⁷ Ω, backflow of electricity from the outside can be prevented.

FIG. 3 shows an example in which the insole of this invention is used in slippers.The insole main body 1 of the embodiment shown in FIG. , the front end of the conductor 7 is fixed to the side surface of the bottom plate 17, and the end is brought into contact with the floor surface 9.

The insole main body is not limited to the above-mentioned example, but may be made of a suitable material that has been added with conductivity or has been treated with antistatic treatment, and at least the surface that touches the human body has a resistance that is slightly higher than that of the human body, and the other parts have a resistance that is slightly higher than that of the human body. resistance value or less. Therefore, for example, the insole main body may be made of metal fibers such as copper, and an oxide film having a resistance value lower than that of the human body may be formed around the outer periphery of these fibers.

[Effect of the invention]

As described above, this invention instantly eliminates static electricity generated between the human body wearing the footwear and the human body by placing it on the sole plate of footwear, thereby eliminating the need for electronic components that are prone to static electricity damage. It is safe to wear this invented footwear when performing assembly work or operating computers, etc., and there is no risk of damaging electronic parts or computers. Furthermore, this invention is an insole, and it has the above-mentioned effect just by placing it on conventional footwear, so it is versatile and extremely convenient. As mentioned above, this can also be used for slippers, etc. In this case, the insole body is sewn onto the floorboard of the slipper, fixed with adhesive etc., and the front part of the conductor tip is fixed in an appropriate place so that the tip part is always on the floor. Make contact. This provides the same effect as described above. In addition, the insole body or the surface of the insole body that comes into contact with the human body is made slightly larger than the resistance of the human body to allow static electricity to pass through, but not to allow so-called dynamic electricity to pass through. However, there is no risk of external electricity flowing back into the human body, and it is safe.
