By this arrangement, the static electricity is subjected to atmospheric discharge and earthed, and the mat 11 for an automobile is prevented from being slipped.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to an antistatic structure for an automobile mat, and more specifically, it prevents dirt and grime from adhering to the automobile mat, and also prevents the human body from being contaminated. This invention relates to an anti-static structure for automobile pine (pine) that prevents static electricity.

(Prior Art) Conventionally, automobile mats have been commercially available, which are made of a base fabric using insulating fibers and piles made of insulating fibers set into a predetermined volume.

However, since these car mats are manufactured from an insulating material, static electricity is easily generated due to friction with shoes or pants when getting in and out of a car or while driving. Ta.

As a result, the automobile mat becomes electrically charged, tends to attract dust and dirt, and becomes easily dirty, resulting in the problem that it must be cleaned frequently. Also, due to static electricity generated by friction, not only the car mat but also the human body becomes electrically charged.When a person touches a metal part of a car while getting in or out of the car, the static electricity accumulated in the human body is immediately transferred to the metal part. It was grounded and gave a huge electric shock to the human body.

In order to solve this problem, it has been proposed to use a conductive material as the material for car mats to prevent the generation of static electricity.

As such a car mat, for example, Japanese Patent Laid-Open No. 61
There is one described in JP-110632.

As shown in Figure 5, this automobile mat (1) uses conductive fibers (3) in some of the threads constituting the base fabric (2) to form a conductive base fabric (2). In addition, a connection coat (4) for electrical connection with the vehicle body is attached to one end of the automobile mat (1).

In this car mat (1), the other end of the connecting coat (4) is attached to the car body side, so that friction caused by friction with the hem of shoes or pants when getting in and out of a car or driving etc. Static electricity is grounded to the vehicle body.

(Problem to be solved by the invention) However, in the automobile mat described in JP-A-61-110632, the static electricity generated by the connection coat attached to one end of the automobile mat is transferred to the vehicle body. Since the car mat is designed to be grounded at the same time, when getting on or off the car, the mat may slip and come off the connection coat from the car body, making it impossible to ground the car. Also, JP-A-61-
In the automobile mat described in Japanese Patent No. 110632, it was necessary to provide a mounting part exclusively for grounding to attach the connection coat to the vehicle body.

The present invention was made in view of the above-mentioned problems, and the problems to be solved are the adhesion of dirt and dust to the car mat due to static electricity generated on the car mat, and the risk of damage to the human body when grounding. It is an electric shock.

The present invention provides an antistatic structure for an automobile mat that reliably removes static electricity generated on the automobile mat, prevents dust and dust from adhering to the automobile mat, and prevents charging of the human body. The purpose is to provide

(Means for Solving the Problems) In order to achieve the above object, the invention according to claim 1 provides the following advantages: The antistatic structure of the mat includes a ring attached to the car mat and a hook fixed to the car floor surface, which hooks the ring and prevents the car mat from shifting, and is made of conductive material. A conductive net made of conductive wire is disposed between the base fabric and the backing layer so as to be in contact with the conductive fibers included in the pile of the base fabric, and a conductive net is disposed on the automobile mat. A mark display section having a conductive layer is provided,
The gist of the patent is ``Antistatic structure for an automobile mat, characterized in that the conductive net is connected to a ring.''

In addition, as in the antistatic structure of the automobile mat according to claim 2, the conductive paper is made by using conductive short fibers on the entire back surface of the base fabric, and one of the conductive short fibers is coated on the surface of the conductive paper. A piece of conductive paper protruding from the top is pasted so as to be in contact with the conductive fibers included in the pile of the base fabric, and a conductive net or a piece of conductive paper is pasted between the conductive paper and the banking layer so as to make contact with the conductive paper. It may be placed in

(Function of the invention) Therefore, in the antistatic structure of the automobile mat according to claim 1, some of the static electricity generated by friction with the hem of shoes or pants when getting in and out of a car or while driving is absorbed by the base fabric. The electric discharge is made in the air through the conductive layer of the mark display section provided on the conductive fiber car mat included in the pile. The remaining static electricity is conducted between the pile and the backing layer through a conductive net placed in contact with the conductive fibers of the pile to a ring made of conductive material connected to the conductive net.

Alternatively, it is guided from the conductive net to the ring via the conductive layer of the mark display section. The ring is hooked onto a hook made of a conductive material that is fixed to the floor of the vehicle, and the static electricity introduced to the ring is transmitted through the hook to the floor of the vehicle. At the same time, since the ring of the car mat is hooked on a hook fixed to the floor of the car, the car mat is prevented from shifting.

Further, according to the antistatic structure of the car mat according to claim 2, static electricity generated by friction with the hem of shoes or pants when getting in and out of a car or while driving is absorbed by the conductive fibers and bases contained in the pile. The static electricity is absorbed by the conductive paper through the conductive short fibers protruding from the surface of the conductive paper attached to the entire back of the cloth, and the static electricity absorbed by the conductive paper passes through the conductive net placed between the conductive paper and the backing layer. The conductive net leads to a connecting ring made of conductive material.
