【Example】

[0014] Below, the antistatic structure of the automobile mat of the present invention will be explained in detail according to an embodiment shown in the drawings.

The automobile 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.

[0018] 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 automobile mat. The conductive fibers 15 are transferred to the conductive base fabric 12 through the conductive fibers 15 .

As shown in FIG. 2, piles 13 are driven into the conductive base fabric 12 constructed as described above so as to form a substantially U-shape, and are lined with a backing material 14. An annular metal fitting is attached to the automobile mat 11 configured in this manner.

The annular metal fitting 16 is a metal ring such as an eyelet, and is attached by caulking so as to penetrate the conductive base fabric 12 from above and below. Therefore, when this annular metal fitting 16 is fitted into a conductive hook 17 protruding from the car floor surface Y, static electricity transferred from the human body to the conductive base fabric 12 collects on the annular metal fitting 16. 16, a ground discharge is made to the car floor surface Y through the hook 17.

Furthermore, the inner diameter of the annular metal fitting 16 is formed to be approximately the same as the outer diameter of the hook 17, which will be described later, so that even if the automobile mat 11 shifts when the annular metal fitting 16 is fitted into the hook 17, The annular metal fitting 16 does not rattle,
The contact state between the annular metal fitting 16 and the hook 17 is maintained. For this reason, the annular metal fitting 16 and the hook 17
There is no problem that the ground discharge does not occur due to non-contact between the two.

[0022] The hook 17 is a projection protruding from the car floor surface Y, and the hook 17 is a protrusion that protrudes from the car floor surface Y. It is fixed on the car floor surface Y with the This hook 17 is molded from synthetic resin, and a layer made of a conductive material such as metal or carbon is formed on its surface to impart conductivity. Note that the entire hook 17 may be made of a conductive material such as metal.

It should be noted that the present invention is not limited to what is shown in the embodiments; for example, the annular metal fitting 16, the hook 1
The mounting position and number of parts 7 can be changed as appropriate within the scope of the claims, such as changing the mounting position and number according to the type of car and the size of the interior of the car.

[Effect of the invention] By having the above configuration, claim 1
In the antistatic structure of the automobile mat described above, when the human body comes into contact with the automobile mat, static electricity charged on the human body is transferred to the conductive base fabric containing the conductive material, and the electrostatic charge is further transferred to the conductive base fabric containing the conductive material. A ground discharge is made from the annular metal fitting attached so as to penetrate the base fabric to the automobile floor surface through the hook into which the annular metal fitting is fitted. Therefore, in the antistatic structure of the car mat according to claim 1, there is no need for a connection cord to ground and discharge static electricity to the car body, and the other end of the connection cord comes off from the connection point on the car body and is grounded. Problems such as not being able to discharge, connection cords getting in the way, and insufficient cleaning will not occur. Further, since the annular metal fitting attached to the conductive base fabric is fitted into a hook protruding from the floor of the automobile, it is possible to prevent the automobile mat from shifting when getting on or off the vehicle. In addition, in the antistatic structure of the automobile mat according to claim 2, when the human body comes into contact with the automobile mat, static electricity charged on the human body passes through the conductive fibers contained in the pile to the conductive base fabric. It is supposed to move to. The effect of grounding static electricity can be further enhanced. Furthermore, in the antistatic structure of the automobile mat according to claim 3, since the inner diameter of the annular metal fitting is formed to be approximately the same as the outer diameter of the hook, when the annular metal fitting is fitted into the hook, Even if the automobile mat is displaced, the annular metal fitting does not shake, and the contact state between the annular metal fitting and the hook is maintained. Therefore, there is no problem that the annular metal fitting 16 and the hook 17 are out of contact and a ground discharge is not caused.
