[Detailed description of the invention]

0001

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 made 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. .

0004

[Problem to be Solved by the Invention] However, with this anti-static mat, one end of the connection cord is fixed to a part of the anti-static mat. Even if there was a change in the connection position of the other end, it could not be adequately handled.

[0005] Furthermore, when cleaning the antistatic mat, the connection cord fixed to the antistatic mat gets in the way, making it difficult to clean the mat thoroughly.

The present invention has been developed in view of the above circumstances, and can adequately accommodate changes in the connection position of the other end of the connection cord due to differences in vehicle types and interior space. The object of the present invention is to provide an antistatic mat that is easy to handle.

[0007]

[Means for Solving the Problems] In order to achieve the above object, the invention as claimed in claim 1 provides a structure in which piles are driven into a conductive base fabric containing a conductive material such as carbon, and which is lined with a backing material. An antistatic mat consisting of
A charging device characterized in that the peripheral edge of the mat is overlocked with an overlock yarn containing conductive fibers, and one end of a connection cord that can be electrically connected to the vehicle body is removably connected to the overlock portion. Its gist was ``Prevention Mat''.

[0008] The gist of the invention as claimed in claim 2 is ``an antistatic mat characterized in that the pile contains conductive fibers.''

[0009]

[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 The overlock yarn containing conductive fibers on the periphery of the mat leads to the overlocked part, and the connection cord, one end of which is removably connected to the overlock part, causes a ground discharge to the vehicle body. It has become. Therefore, the connection cord can be connected anywhere around the periphery of the mat.

Further, in the antistatic mat according to claim 2, 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 through the conductive fibers contained in the pile. It is designed to move.

【Example】

[0011] Below, the antistatic mat of the present invention will be explained in detail 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 include 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.

[0015] 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. The periphery of the antistatic mat 11 constructed in this way is overlocked by the overlock yarn 16.

The overlock yarn 16 contains conductive fibers such as carbon fibers and metal fibers, and the periphery of the antistatic mat 11 is overlocked with a predetermined density by the overlock yarn 16. Therefore, when one end of the connection cord 17 that can be electrically connected to the vehicle body is connected to this overlock part, the static electricity transferred from the human body to the conductive base fabric 12 collects at the overlock part on the periphery of the mat. Overlock 16, connection code 1
7, and a ground discharge is made to the vehicle body side.

A clamping fitting such as a clip is attached to one end of the connection cord 17 that connects to the antistatic mat 11 side, and the other end is attached to a metal part of the vehicle body, such as a leg under the seat, and screwed. A ring 18 for stopping is attached.

It should be noted that the present invention is not limited to what is shown in the embodiments; for example, the number of conductive fibers included in the overlock thread 16, the length and attachment position of the connecting cord 17 can be changed depending on the vehicle model and the mounting position. Change it depending on the size of the inside of the car, etc.
Changes may be made as appropriate within the scope of the claims.

[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.
The conductive material is transferred to a conductive base fabric containing a conductive material, and is further guided to an overlocked portion by an overlock thread containing conductive fibers at the periphery of the mat, and is removably connected at one end to the overlock portion. The connection cord connected to the battery discharges ground to the vehicle body. Therefore, the connection cord can be connected anywhere around the periphery of the mat, and even if the connection position of the other end of the connection cord is changed due to different vehicle types and vehicle interior spaces, it can be adequately accommodated. In addition, the connection cord does not get in the way and does not cause problems such as insufficient cleaning. Further, in the antistatic mat according to claim 2, 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 through the conductive fibers contained in the pile. It looks like this. Therefore, the effect of grounding static electricity can be further enhanced.
