Description

  The present invention relates to an antistatic shoe that reduces static electricity charged on a human body not only in the sole of the shoe but also in the upper part by natural discharge into the atmosphere.

  The human body easily generates static electricity by various actions, contact with a charged object, and electrostatic induction action from the charged object, and easily charges when insulated from the ground. For example, in a dry environment such as winter, static electricity is easily generated due to friction of clothes and the like, and the static electricity is charged to a human body as it is because natural discharge cannot be expected. The static electricity that remains in the human body is discharged under a high voltage at once when a charged person's hand touches a conductive metal part such as an iron door or a car door handle, causing an unpleasant electrostatic shock. It can be painful or severely painful. In addition, it also causes clinging and fluffing of clothes that ruin wearing. In view of the above, various conductive shoes have been proposed which have conductivity so that static electricity charged on the human body is grounded from the shoe sole to the ground (ground).

  As a specific configuration of this type of conductive shoe, in a conductive shoe in which the sole is constituted by an insole and an outsole, and the outsole and the midsole have a two-layer structure, the outsole and the insole Is formed of a conductive material, the midsole is formed of a nonconductive material, and a flexible conductor is coiled inside the midsole so as to electrically connect the upper surface of the outsole and the lower surface of the midsole. There is a conductive shoe in which a conductor configured in a tape-shaped body is embedded (for example, see Patent Document 1).

  When a conductive shoe of this configuration is worn, an electrical conduction path is always formed under the foot in the order of the insole, the conductor, and the outsole, so that the static electricity charged to the human body passes through the outsole and passes through the floor or the ground. It is possible to leak (discharge) to the human body and to eliminate human body charging.

However, depending on the place where the person wearing the conductive shoes described above acts, there is a place where discharge from the shoe sole is almost impossible. For example, on a carpeted floor or an insulated floor in a room, electrostatic discharge to the floor cannot be expected. Also, the presence of socks worn by the wearer of the shoe may prevent the human body from energizing to the outside via the shoe sole. Therefore, a conductive shoe that discharges static electricity charged on a human body only through the sole of a shoe causes unevenness in the discharge effect even in a location.
Japanese Utility Model Publication No. 7-15443.

  The present invention has been made in view of such a situation, and enables natural discharge not only to the sole of the shoe but also to the atmosphere from the instep portion of the shoe, and the static electricity charged to the human body is generated in a certain place. It is an object of the present invention to provide an antistatic shoe which can be reduced without knowing any restrictions.

  In order to achieve the above object, the antistatic shoes according to the present invention employs a polyurethane sole containing a conductive substance, with respect to the upper formed in a bag shape by lining the upper with a conductive backing, The conductive soles are molded by a direct pouring method.

  According to the present invention configured as described above, from the sole of the shoe wearer, static electricity charged on the human body is grounded to the floor or the ground through the conductive sole made of the polyurethane sole containing the conductive substance. . Also, since the upper part of the shoe wearer's foot is in contact with the conductive backing constituting the upper of the shoe, static electricity charged to the human body through this conductive backing causes natural discharge to the atmosphere. As a result, there is no place restriction and static electricity charged on the human body can be effectively reduced.

  In the above-described configuration, when the insole formed of a conductive material is adhered with a conductive adhesive on the sole of the sole made of polyurethane sole, the discharge effect of static electricity charged on the human body remains unchanged, The cushioning properties of the shoe are enhanced, and the feeling of wearing is improved.

  According to the antistatic shoes according to the present invention, static electricity charged on the human body is grounded to the floor or the ground through the conductive soles, and the static electricity is also transmitted from the conductive backing constituting the upper of the shoe. Since it is naturally discharged into the atmosphere, there is no place restriction and static electricity charged on the human body is effectively reduced. Therefore, it is possible to prevent an unpleasant electrostatic shock or a severe pain caused by a sudden discharge of static electricity, and it is possible to prevent an electrostatic disaster caused by human body charging.

Preferred embodiments of the antistatic shoe according to the present invention will be described with reference to the accompanying drawings.
(Embodiment)
FIG. 1 is a cross-sectional view of a tread portion of an antistatic shoe according to the present invention, and FIG. 2 is a perspective view of the antistatic shoe.

  As shown in the figure, an antistatic shoe A according to the present invention has an upper 3, which is sewn into a foot-shaped bag by lining a conductive backing 2 on an upper 1, and a polyurethane containing a conductive substance. The sole 4 is formed by using a sole and by a direct pouring method. In the embodiment, the shoe sole 4 is formed by sequentially forming the midsole 4b and the insole 4c on the outsole 4a.

  In making the sole 4 conductive, carbon black, metal powder, or the like is used as a conductive substance to be mixed with the polyurethane sole.

  As the conductive backing material 2 lined with the upper shell 1, a backing woven with conductive fibers is used. In the embodiment, it is preferable to use a conductive fiber belton (trade name) manufactured by Kanebo Gosen Co., Ltd. and an antistatic material Doden (trade name) obtained by mixing and knitting a polyester material.

  In addition, a conductive adhesive is used for bonding each part. As the conductive adhesive, a commercially available product obtained by mixing a conductive material such as a conductive powder and a conductive fiber into a binder resin and, if necessary, diluting with a solvent or the like is used.

  In the above-described configuration, when doden (trade name) is used as the conductive backing 2 lined with the upper shell 1, the antistatic effect of the conductive fiber belton (trade name) mixed in the backing 2 is mainly Neutralization of charge by corona discharge and transfer and diffusion of charge.Even if the conductive fiber is mixed in a small amount, it exhibits extremely high static elimination ability and suppresses electrification due to friction even in low humidity environment. In addition, it exhibits a high static elimination ability to remove static electricity on the fiber to prevent static electricity from being charged to the human body.

  Also, the antistatic shoes according to the present invention have passed the electrical resistance standard value as the safety shoes defined by JIS, even from the test results of the antistatic performance of the products of the present invention.

  The antistatic shoes according to the present invention reduce the static electricity charged on the human body not only from the sole of the shoe but also from the upper part of the shoe by natural discharge into the atmosphere, so that any place where the human body is disliked to be charged It is useful to wear with.
