Hereinafter, with reference to the accompanying drawings antistatic shoes according to the present invention will be described in detail.

1 is a perspective view of a first embodiment of an antistatic shoe according to the present invention, FIG. 2 is an exploded perspective view of the corona discharge unit employed in FIG. 1, FIG. 3 is a sectional view taken along line III-III ′, and FIG. 4. 2 is a perspective view illustrating another example of the corona discharge unit employed in FIG. 2.

As shown, the first embodiment of the antistatic shoe according to the present invention, the sole 10 for supporting the bottom; A shoe upper 20 provided on an upper portion of the sole 10; As installed on the sole 10 or the shoe upper 20, the corona discharge portion 30, 30 'to remove the static electricity generated by being electrically connected to the wearer's foot through the corona discharge; includes. In order to facilitate the description in the present embodiment will be described with an example that the corona discharge portion 30, 30 'is installed in the groove (10a) formed in the sole 10.

Sole 10 may have conductivity. To this end, the resin for molding the sole 10 is to be conductive, in order to make the conductivity is mixed with carbon or conductive metal particles or metal fibers in the resin. An insole (not shown) that provides a cushion may be installed on the upper side of the shoe sole 10, in which case the cushion should also have conductivity. Thus, the sole 10 is electrically conductive, the foot of the wearer is electrically connected to the corona discharge portion 30 to be described later.

Shoe upper 20 is conductive, it may be implemented in leather / leather or fabric. When the shoe upper 20 is embodied in leather or leather, a conductive sheet is attached to the inner surface of the shoe upper 20. In addition, the shoe upper 20 may be implemented in the form of a fabric, in which case the fabric may be made of a carbon yarn to make it conductive, or may be implemented by coating a synthetic resin containing an antistatic agent on the fabric.

The body 31 has a rectangular shape in this embodiment, but may be implemented in various shapes such as circular or elliptical. The discharge part 32 is a portion where corona discharge occurs and has a large number of conductive fibers 32a having sharp or rounded ends. Charges opposite to the charged body (the wearer's foot) are induced in the discharge part 32. The induced charges move to the end of the conductive fiber 32a and are removed by corona discharge. That is, when the charge is moved to the end of the conductive fiber 32a, the electric field is strong at the end of the conductive fiber 32a, thereby causing partial discharge (corona discharge) as the air is ionized to remove static electricity. The conduction band 33 electrically connects the discharge part 32 to the sole 10 or the shoe upper 20 having conductivity, and is made of copper sulfate composite fiber, and thus has very low resistance.

On the other hand, the corona discharge portion 30 ′ may be installed in the sole 10 or the shoebox shell 20 which does not have conductivity. To this end, the corona discharge portion 30 'is a body 31' installed in the sole 10 or the shoe upper 20, as shown in Figure 4, and the end is installed in the body 31 ' Discharge part 32 'to which the cut conductive fiber 32a' is attached, and electrically connecting through the shoe sole 10 or the shoe upper 20 to electrically connect the discharge part 32 'to the wearer's foot ( 33 '). The conductive passage 33 'must pass through the sole 10 or the shoe upper 20, and is illustrated in the form of a rivet in FIG. 4 for better understanding. Such a conductive passage 33' is a discharge portion ( It penetrates the through-hole 32b formed in 32. However, such a conductive passage 33 'may be implemented in various other shapes, of course.

The corona discharge portion 30 ′ of FIG. 4 is fixed to the sole 10 or the upper shoe 20 by the conductive through hole 33 ′ and is electrically connected to the foot of the wearer. To this end, a separate conductive member is installed inside the shoe to electrically connect the wearer's foot and the conducting passage 33 '. There are various forms of such conductive members, for example, there may be a wire or conductive sheet attached to the inner wall of the shoe.
