JPS5932323Y2 - Footwear to prevent static electricity - Google Patents

Description

[Detailed Description of the Invention] The present invention aims to provide footwear that prevents the human body from being charged with static electricity.

Below, the embodiments of the present invention will be explained based on the drawings: 1
are conductive shoes, 1.0X10Q and 1.0X10. It has an electrical resistance value between Q.

Reference numeral 2 denotes a leg strength bar that covers the chest area of the wearer of the conductive shoe 1, and extends the lower side of the fabric 4 woven with conductive fibers 3 from the opening edge 5 of the conductive shoe 1 through the inner surface of the shoe 1 to the entire surface of the midsole 13. Alternatively, the fabric 4 is cut so as to be in contact with a part of the fabric 4, and mutually removable fasteners 6 are sewn 7 on both edges of the fabric 4 to form a cylinder 8 that can be opened and closed. 2. As shown in the figure, it is inserted into the conductive shoe 1 and sewn 9 along the opening edge 5.

Reference numeral 10 denotes a rubber cord inserted through the upper end edge of the leg strength bar 2, and is used to tighten the upper end edge of the leg strength bar 2 to the leg of the wearer of the conductive shoe 1.

Reference numeral 11 denotes a rubber cord sewn to tighten the ankle portion of the leg strength bar 2.

Next, to explain the function of the antistatic footwear constructed as described above, a worker or the like puts on the conductive shoes 1 and puts the part of work pants below the knee inside the leg strength bar 2. If you are standing on the ground or on a floor that is electrostatically grounded with your chest covered, and your work clothes are charged with static electricity, there will be a gap between the leg strength bar 2 containing conductive fibers and your body. Since an equal electric field is formed and the leg strength bar 2 is in electrical contact with the midsole 13, airborne ions are generated between the conductive fibers 3 and the human body, and a conductive path is formed by corona discharge. Static electricity is safely leaked from the human body through the sole of the conductive shoe 1 to the earth or a floor surface that is electrostatically grounded to the earth.

The conductive shoe 1 originally has the function of leaking static electricity through the sole and preventing electric shock caused by low voltage electricity.
When used in a place where there is no risk of electric shock, a conductive shoe may be used instead of the conductive shoe 1, and a conductive leg strength bar may be attached to it.

Since the present invention is constructed as described above, even if static electricity is charged on the human body, it can be safely leaked through the sole of the shoe to the earth or to a floor surface that is electrostatically grounded to the earth, compared to leakage due to air discharge. It has an excellent leakage effect, suppresses the rise in potential, weakens electrostatic force, does not cause electric shock to the human body, reduces dust adhesion to clothes, and allows the hem of pants to be covered with leg strength bars. , prevent dust from coming out from the hem opening onto the floor or into the air.

Therefore, there is a risk of ignition or explosion in clean rooms where dust and bacteria should not adhere in fields such as semiconductor device manufacturing, pharmaceutical manufacturing, precision machinery industry, IC and LSI assembly processes, or sparks caused by charged static electricity. It is extremely suitable as footwear for use when working in places.

In addition, since the conductive shoes or conductive shoes and the leg strength bar are integrated, compared to wearing conductive shoes or conductive shoes and an aperge use, there is no need to put them on, and the shoes can be worn inside the aperge use. It doesn't move and is easy to wear.

On the other hand, it has various effects such as being able to safely protect the feet compared to wearing only opaque shoes.
