BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an antistatic mat that can reliably remove static electricity generated inside a vehicle.

0002

2. Description of the Related Art Conventionally, there is an antistatic mat described in Japanese Patent Application Laid-Open No. 110632/1983, which has been developed for the purpose of completely removing static electricity generated inside a vehicle.

[0003] As shown in FIG. 3, this antistatic mat 1 is made up of a conductive base fabric 2 woven using conductive threads as part of the threads constituting the base fabric, and piles 3 . One end of a connection cord 4 that can be electrically connected to the car body is fixed to a part of the antistatic mat 1, and the other end is connected to a metal part of the car body to completely eliminate static electricity. .

[Problems to be Solved by the Invention] However, in this antistatic mat, since the conductive base fabric is woven using conductive thread, it is difficult to attach the name plate to the mat. The current high-frequency welding process generated sparks and failed to weld properly. Another method is to attach a name plate by heat welding, but in this case the heating process takes a long time, resulting in the problem that the heat from the heat welding spreads to the surrounding area.

Furthermore, with this antistatic mat, one end of the connection cord is fixed to the surface of the car mat, which makes it look bad, and the connection cord is easily removed when getting on and off or cleaning the mat. There was a risk that the connecting part would be damaged.

The present invention was developed in view of the above circumstances, and has a mounting structure that allows the name plate to be easily attached, and also allows the connection cord to be connected when getting on and off or cleaning the mat. The object of the present invention is to provide an antistatic mat with less risk of damage to connecting parts.

[0007]

[Means for Solving the Problems] In order to achieve the above object, the invention according to claim 1 provides an antistatic mat comprising conductive base fabric containing conductive material such as carbon and piles driven into it. By tightening the mat with a name plate that has a conductive rivet shaft formed on the back side, the name plate is attached to the mat surface and is also attached to one end of the connection cord that can be electrically connected to the vehicle body. an antistatic mat, characterized in that a ring is inserted through the rivet shaft of the name plate.
was its gist.

[0008]

[Function] In the antistatic mat according to claim 1, when the human body comes into contact with the antistatic mat, static electricity charged on the human body is transferred to the conductive base fabric containing the conductive material, and A connection cord with a ring at the end inserted into the rivet shaft on the back of the nameplate allows for ground discharge to the vehicle body.

[0009]

【Example】

[0010] The antistatic mat of the present invention will be explained in detail below according to an embodiment shown in the drawings.

The antistatic mat 11 according to the present invention is shown in FIG.
As shown in FIG. 2, a plurality of piles 13 are driven into a conductive base fabric 12 to create a predetermined volume, and this is lined with a backing material 14 made of synthetic resin such as thermoplastic resin. .

The conductive base fabric 12 of the present invention is preferably paper, nonwoven fabric, woven fabric, or the like containing powder or fiber of a conductive material such as carbon, metal, or conductive ceramics. In addition, after driving piles into paper, nonwoven fabrics, and textiles, carbon is added to the adhesive applied to prevent piles from falling out.
It is also possible to use a base cloth that is impregnated with powder or fibers of a conductive material such as metal or conductive ceramics to impart conductivity.

The fibers used for the pile 13 are acrylic, polyester,
Fibers such as polyamide are preferred because they easily conduct negative electricity, and acrylic fibers are particularly preferred from the viewpoint of economy and tactility. The pile 13 of the present invention is made by bundling a plurality of such synthetic fibers to have a thickness of 300 to 500 deniers.

[0014] The pile 13 may also contain conductive fibers 15 such as carbon fibers. In this case, static electricity charged on the human body is absorbed into the pile when the human body comes into contact with the antistatic mat. The conductive fibers 15 are transferred to the conductive base fabric 12 through the conductive fibers 15 . As shown in FIG. 2, the pile 13 described above is driven into the conductive base fabric 12 in a substantially U-shape and is lined with a backing material 14. A name plate 16 is attached to the surface of the antistatic mat 11 constructed in this way.

The name plate 16 is made of a conductive material such as metal or conductive ceramics, and has a rivet shaft portion 18 formed on its back surface. The name plate 16 may be formed of synthetic resin and then coated or sprinkled with metal or carbon powder to provide conductivity. The name plate 16 is attached to the surface of the antistatic mat 11 by inserting the rivet shaft portion 18 of the name plate 16 into a hole previously formed at a predetermined position of the antistatic mat 11 and tightening it.

Further, the rivet shaft portion 18 of the name plate 16 is provided with a connection cord 17 that can be electrically connected to the vehicle body.
A ring 19 attached to one end is inserted, and the ring 19 is also tightened and fixed at the same time as the rivet shaft portion 18 is tightened. In this way, the connection cord 17 is connected to the name plate 16 on the back side of the antistatic mat 11.

[Effect of the invention] By having the above configuration, claim 1
In the antistatic mat described above, static electricity charged on the human body is removed when the human body comes into contact with the antistatic mat.
It moves to a conductive base fabric containing a conductive material, and is further grounded to the vehicle body by a connecting cord whose end ring is inserted into the rivet shaft on the back of the name plate. Therefore, in the antistatic mat according to claim 1, the name plate can be easily attached, and there is less risk of damage to the connecting portion of the connecting cord when getting on and off or cleaning the mat. can do.
