BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an antistatic mat. More specifically, the present invention relates to an antistatic mat capable of instantaneously removing static electricity charged by a human body in a vehicle and removing discomfort caused by a discharge phenomenon at the time of getting on and off the vehicle.

[0002]

2. Description of the Related Art Conventionally, as this kind of antistatic mat, there is one described in JP-A-61-110632. As shown in FIG. 4, this antistatic mat 1 is formed into a conductive base cloth by using a conductive yarn 3 for a part of the yarn constituting the base cloth 2, and a vehicle body is attached to one end of the antistatic mat 1. A connection cord 5 for electrical connection to the side is attached. And in this antistatic mat,
The other end of the connection cord 5 is attached to the vehicle body so that static electricity generated by friction with the skirts of shoes or trousers at the time of getting on or off the vehicle or during driving is grounded to the vehicle body.

[0003]

However, in this antistatic mat, static electricity is grounded from the human body to the vehicle body by a connection cord attached to one end of the antistatic mat. In some cases, the connection mat was displaced from the vehicle body side when the prevention mat was displaced when getting on or off the vehicle, and the ground could not be grounded. Further, in order to attach the connection cord, it is necessary to provide a groundable attachment portion on the vehicle body side. Further, since the body of the automobile itself does not directly contact the ground, it is necessary to attach a grounding means such as a ground belt for grounding the static electricity of the charged body to the body.

The present invention has been made in view of such a problem, and a problem to be solved is that it is necessary to attach a connection cord for grounding static electricity charged on the mat to a vehicle body side. is there. According to the present invention, static electricity charged to the human body can be instantaneously removed in the vehicle, discomfort caused by a discharge phenomenon at the time of getting on and off the vehicle can be eliminated, and grounding means such as a connection cord and an earth belt are required. It is an object of the present invention to provide an antistatic mat that does not have any effect.

[0005]

In order to achieve the above-mentioned object, the invention according to claim 1 is based on the idea that "a pile 17 containing conductive fibers 16 which is driven so as to penetrate to the back surface of the base cloth 14 and a pile 17 having the same. An antistatic mat comprising a backing layer 12 lined with a back surface of a base cloth 14 for fixing a pile 17, the mat being held on the backing layer 12 and in contact with the conductive fibers 16. The gist of the present invention is an antistatic mat, which is provided with a conductive layer 13 made of a conductive material 20 such as carbon powder.

[0006]

In the antistatic mat according to the first aspect, the static electricity charged on the human body in the car is grounded to the pile 17 of the mat 11 when the human body comes into contact with the mat 11. A part of the static electricity charged on the pile 17 is discharged in the air through the conductive fibers 16 included in the pile 17. Also, a part of the static electricity of the pile 17 is absorbed by the conductive layer 13 made of the conductive material 20 held on the backing layer 12 through the conductive fiber 16 of the pile 17 and provided in contact with the conductive layer 13. The air is discharged in the air through the conductive fibers 16 of the pile 17.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An antistatic mat according to the present invention will be described in detail below with reference to an embodiment shown in the drawings. FIG. 1 is a perspective view showing the antistatic mat of the present invention, FIG. 2 is an enlarged sectional view of the antistatic mat of the present invention, and FIG. 3 is an enlarged sectional view of a portion surrounded by the XY line in FIG. Antistatic mat 1 of the present invention
As shown in FIGS. 1, 2 and 3, a plurality of piles 17 are driven into a base cloth 14 to form a predetermined volume, and this is backed by a backing layer made of a synthetic resin such as a thermoplastic resin. It is. In the antistatic mat 11, the base cloth 14 is made of a nonwoven fabric, a mesh,
Nylon woven cloth etc. cut into a predetermined shape,
In this example, a nonwoven fabric was used. As shown in FIG. 3, a plurality of piles 17 are driven into the base cloth 14 so as to be substantially U-shaped while penetrating to the back surface of the base cloth 14.

[0008] The pile 17 is made of electrically non-conductive synthetic fiber, and the entire surface of the base cloth 14 on the front side is made of the pile 1.
7 and is easily charged. For this reason, when the human body comes into contact with the front side of the antistatic mat 11, the static electricity charged on the human body is easily grounded to the mat 11. The pile 17 to be driven is made of synthetic fiber 15 such as polyamide fiber.
17a, and a conductive fiber 1
And 6 containing 17b. Here, the pile 17b containing the conductive fibers 16 is bundled by adding a plurality of carbon fibers, conductive ceramic fibers, and conductive fibers 16 such as metal fibers to a plurality of synthetic fibers 15 such as polyamide fibers. Are provided to a predetermined thickness. In this embodiment, the conductive fibers 16 used were carbon fibers manufactured from acrylonitrile-based polymer fibers.
The pile 17b configured as described above is placed in contact with a conductive layer 13 that absorbs static electricity described below, and
3 absorbs the static electricity absorbed in the conductive fiber 1 of the pile 17b.
It is considered that air discharge is carried out through 6. As described in the present embodiment, the base cloth 14
It is not always necessary to drive two types of piles 17a and 17b, but only the pile 17b containing conductive fibers may be driven.

As shown in FIGS. 1, 2 and 3, the conductive layer 13 is formed on a backing layer 12 made of a synthetic resin such as a thermoplastic resin by powdery, granular or short-fiber carbon, conductive ceramic. , A conductive material 20 such as a metal is laminated at random, and the backing layer 12 penetrates between the laminated conductive materials 20 and gels, and the conductive material 2
This is a layer in which 0 is held. In this embodiment, carbon fibers manufactured from an acrylonitrile-based polymer were used as the conductive material 20.

Since the conductive layer 13 thus configured is held on the backing layer 12, static electricity grounded to the pile 17 from the human body is absorbed by the conductive layer 13 through the conductive fibers 16. It is thought that it will become. It is also considered that static electricity absorbed by the conductive layer 13 by the conductive fiber 16 in contact with the conductive layer 13 is discharged in the air through the conductive fiber 16.

[0011]

As described in detail above, in the antistatic mat according to the first aspect, the static electricity charged on the human body is absorbed by the conductive layer made of a conductive material held on the backing layer. Air discharge is performed through conductive fibers contained in a pile of a base fabric provided in contact with the conductive layer.

For this reason, according to this antistatic mat, static electricity charged to the human body in the vehicle is instantaneously removed,
Discomfort caused by a discharge phenomenon at the time of getting on / off can be eliminated. Further, according to this mat, since static electricity charged on the human body is removed by air discharge, no grounding means such as a connection cord or a ground belt is required.
