Description

[Detailed description of the invention] [Industrial application field] This invention is attached to the inside of an automobile and removes static electricity from the human body through a member having high resistance conductivity.
This invention relates to a device for preventing shocks caused by static electricity caused by motor vehicle drivers and the like. Specifically, when a person gets out of a car seat due to movement (friction), the static electricity generated between the clothing and the seat surface material can cause damage to the hands of the car driver. The present invention relates to an electrostatic shock preventer that prevents electrostatic shock caused by discharge between metal members of a car body, etc.

[Conventional technology]

For example, in the process of getting on or off a vehicle, the person usually grasps the door handle of the vehicle with one hand to open the door and get on or off the vehicle.

By the way, if a person exits the vehicle with static electricity charged on his body due to friction and peeling between the clothes he is wearing and the surface of the vehicle's seat, it is likely that the person has good conductivity and The above-mentioned handle is made of metal material and is normally installed, so when a person's one hand comes into contact with this handle, the potential difference that occurs between the handle and the person's hand may cause a sudden discharge of static electricity. , electrical shocks are often experienced.

To solve this problem, it has been considered to provide a patch type electrostatic shock preventer as disclosed in, for example, Japanese Utility Model Application Publication No. 51-92067. However, in this case, a material with high resistance conductivity is formed on the front side of the patch-type electrostatic shock preventer, or a high resistor is interposed on the back of the contact member on the front side.
Since static electricity is discharged through the conductive adhesive layer on the back side of the contact member, it was necessary to adhere the patch-type static shock preventer to the conductive metal part of the vehicle. However, because vehicles are painted with insulating paint and many synthetic resin materials are used, there are no suitable conductive metal parts, and there are restrictions on where to install patch-type electrostatic shock preventers. It was hot. For this reason, for example, if the user does not necessarily touch the patch-type electrostatic shock before getting out of the vehicle, the effect of preventing the electrostatic shock has to be reduced.

Furthermore, as disclosed in Japanese Patent Application No. 60-244620,
Another method has been considered in which a patch pen-type electrostatic shock preventer is glued to a keyhole portion of a conductive metal member outside the vehicle. This is called a static elimination plate and is already commercially available, but when you get into the vehicle from outside the vehicle, you touch this static elimination plate to discharge static electricity from your body.
It is less effective when the vehicle is charged with electricity and the user exits the vehicle.

[Problem that the invention attempts to solve]

Therefore, the static electricity charged on the human body can be discharged without an electrostatic shock immediately before the driver, etc. who has been charged inside the vehicle gets out of the vehicle, and the driver, etc. who is about to get out of the vehicle can discharge it very easily and easily. Remember, there was a need for an electrostatic shock preventer that could be easily installed in a location where static electricity accumulated on the human body could be discharged.

Therefore, the present invention is an electrostatic shock prevention device that can be easily installed by adhesively attaching it to the vicinity of the knob that opens and closes the vehicle door, which is installed inside the vehicle and which the driver, etc. always comes into contact with when getting out of the vehicle. To provide an electrostatic shock preventer which can effectively discharge static electricity to a conductive metal part even if there is no conductive metal part on the back side of the electrostatic shock preventer.

[Structure of the idea]

To this end, the present invention provides a contact plate with high resistance conductivity, and a wiring member made of a flexible lead wire made of a good conductor, one end of which is electrically connected to the contact plate. One end is fixed to the contact plate, and a mounting member having an adhesive layer is provided on the side in contact with the contact plate and the side opposite to the contact plate.

Further, a plate-like member having a conductive portion is electrically connected to the other end of the wiring member. and,
A cover member is provided which is adhered to this plate-shaped member and fixes the other end of the wiring member 7 to the plate-shaped member.

[Effect]

As a result, even if there is no conductive metal part on the back side of the high-resistance conductive member, the wiring member made of the flexible lead wire made of a good conductor can move static electricity away from the contact plate that has high-resistance conductivity. can be guided to a certain conductive metal part, where static electricity can be discharged.

Moreover, the attachment member can bond the contact plate to any part of the vehicle, and can also securely fix one end of the wiring member to the vehicle.

Furthermore, the other end of the wiring member can be fixed to the vehicle via the plate member, and the cover member reliably maintains the electrical connection between the other end of the wiring member and the plate member having the conductive portion. be able to.

[Effect of idea]

As a result, the present invention can discharge static electricity even if there is no conductive metal part on the back side of the contact plate with high resistance conductivity. A high-resistance conductive contact plate can be relatively freely adhered to parts that passengers will almost certainly touch with their hands, and static electricity can be transferred to conductive metal parts located further away via wiring members. It becomes possible to discharge without electrostatic shock. In addition, when connecting the wiring member to the conductive metal part of the vehicle, the wiring member and the conductive metal part of the vehicle can be easily connected by bonding a plate-like member having a conductive adhesive part onto the conductive metal member. This has the effect that the vehicle user can easily install the electrostatic shock preventer without using screws or the like.

In addition, in one embodiment of the present invention, the wiring member is made of a flat lead wire, so it can be installed in the vehicle without being noticeable, and since the wiring member is flat, there is no wiring member between the contact plate and the mounting member. Even if the contact plate is pinched, extreme protrusions are not formed on the contact plate, and the entire contact plate can be made into a flat shape that does not feel strange when contacted. In addition, the wiring member made of the flat lead wire is also held between the cover member and the plate member, but in this case as well, the flat lead wire is inserted into the narrow gap between the cover member and the plate member. Because of its shape, it can be easily held.

Furthermore, by forming the mounting member and the cover member with a cushion member whose volume can be increased or decreased, that is, having a cushioning characteristic such that a recess is easily formed, the wiring member can be formed between the contact plate and the mounting member. When sandwiched between the wiring members, the volume of the wiring member can be absorbed by the mounting member having cushioning properties, and an electrostatic shock preventer can be obtained in which the overall shape is not distorted by the wiring member. Similarly, when a wiring member is sandwiched between a plate-like member and a cover member, deformation of the cover member due to bending of the lead wire of the wiring member and deformation of the plate-like member can be absorbed by the cushioning characteristics, and the cover It is possible to provide an electrostatic shock preventer in which the surface of the member can be made flat and wrinkles caused by the wiring member are not formed after installation. In addition, when a light reflective layer is provided on the surface of this cover member, it is possible to easily detect when the vehicle door is opened or closed from outside the vehicle while the cover member is in contact with the conductive metal part of the vehicle door. It can be recognized.

A release paper 64 is provided on the surface opposite to 71. When adhering the contact piece 6 to the metal part of the car, the insulating release paper 64 is removed and the conductor 71 is bonded to the metal part of the car via the conductive double-sided tape 62. It is something. Note that 63 is a decorative paper adhered to the opposite side of the non-conductive cushioning double-sided tape 61. In FIG. 3, the cover member according to the present invention is composed of a non-conductive cushioning double-sided tape 61 and a decorative paper 63, and the wiring member 7 is composed of the cover members 61, 63 and a conductive double-sided tape 62. It is held between a plate-like member having conductivity and flexibility. In addition, in FIG. 3, a reflective layer is provided on the lower surface of the decorative paper 63. this is,

FIG. 4 is a perspective view of the wiring member 7, in which the surface of a flat metal conductor 71 is covered with an insulator 7 such as a synthetic resin.
It consists of a flat lead wire overcoated with 2.

When the driver's hand touches the contact plate 51, which has high resistance conductivity, the electrostatic charge on the driver's body is transferred to the wiring member 7 via the contact plate 51 and the conductor 71 of the wiring member 7. It is connected to a plate-like member 62 having a conductive adhesive portion electrically connected to the other end. By bonding this plate member 62 to a conductive metal part of the vehicle, static electricity from the human body is discharged to the metal part of the vehicle through at least the contact plate 51 having high resistance conductivity. . Therefore, no sudden current flows during this discharge,
Since the discharge current is limited by the contact plate having high resistance conductivity, the driver and the like are not subjected to electrostatic shock. Further, the contact plate is provided with mounting members, and these mounting members 52, 5
One end of the wiring member is fixed between 3 and 54 and the contact plate 51. Since the mounting member is a member having an adhesive layer on the side in contact with the contact plate 51 and the side opposite to the contact plate 51, the mounting member fixes the wiring member 7 to the contact plate 51 and also adheres the contact plate 51 to the vehicle body. It is possible to perform the following actions. By using the double-sided adhesive tape 53 having cushioning properties as the mounting member, the volume occupied by the wiring member can be absorbed by the cushioning properties of the double-sided adhesive tape 53. Even when the wiring member 7 is inserted, the outer diameter shape of the contact piece 5 is less likely to collapse, and the shape of the connecting portion between the contact piece 5 and the wiring member 7 can be made into a relatively flat shape with few irregularities. Therefore, it can be made into an excellent design. Moreover, since it has this cushioning property, the conductor 71 of the wiring member 7 can be reliably pressed and connected to the conductive adhesive tape 52 and the contact plate 51 using the cushioning force, that is, the elastic force.

It is desirable that the wiring member 7 is a flat lead wire, and in this way it can be attached to the inside of the vehicle without protruding relatively. Further, the contact piece 6 is connected to the other end of the wiring member 7, specifically electrically connected to the other end of the wiring member 7, and has a plate-like member 62 having a conductive adhesive portion. In one embodiment, this plate-like member 62 may be made of conductive double-sided tape, but is not limited thereto. A release paper 64 is pasted on the surface of this plate-like member 62, and when connecting it to an automobile, the release paper 64 is removed by hand and the conductive metal parts of the automobile, that is, as shown in FIG. A plate member 62 is bonded to cover the head of the screw for attaching the locking device.

The electrostatic shock preventer of the present invention can be installed as shown in Figure 1 by installing the first contact piece 5 near the door knob of the vehicle, and attaching the locking device to the head of the installation screw. Although it is most ideal to attach the second contact piece 6 so as to cover the second contact piece 6 and to connect this with a flat lead wire, the attachment location is not limited to the location shown in FIG. The first contact piece is glued according to the preference of the car driver, and from there the second contact piece 6 is connected to the conductive gold part of the car via a wiring member 7 having a predetermined length. Of course, it is also possible to use a structure that discharges static electricity.

Note that the plate-like member 62 may be formed in a plate shape, that is, formed of an adhesive layer formed in a layered manner. Further, the cover member and the mounting member may be made of conductive rubber that is elastic and has a cushioning property.

In addition, if it is better to change the length of the wiring member 7 depending on the vehicle, for example, as shown in FIG. 2, the contact plate 51 and the conductive adhesive tape 52 are separated in advance. Wiring member 7 cut to a specified length by the person installing the electric shock preventer
may be sandwiched between the double-sided adhesive tape 52 and the contact plate 51. Alternatively, in FIG. 3, the wiring member 7 cut to a predetermined length is adhered to the surface of the conductive double-sided tape 62, and the double-sided tape 62

In this case, the length of the wiring member 7 is adjusted on the second contact piece 6 side in FIG. 3. It should be noted that the wiring member 7 may be constructed as a fixed electrostatic shock preventer such that the length thereof cannot be changed.In this case, it is inevitable that the wiring member 7 will loosen to some extent, but the electrostatic shock preventer may be By configuring , this problem will disappear.
Further, although the plate-like member 62 needs to have an adhesive part to the vehicle body, the conductor 71 of the wiring member does not necessarily need to be directly connected to this conductive adhesive part, and it is necessary that the conductor 71 is electrically connected to the plate-like part. Any configuration may be used as long as it is connected to a conductive adhesive portion of the member. Moreover, the cover members 61 and 63 need only be members that cover the connecting portion between the wiring member 7 and the plate-like member 7 so that they cannot be seen from the outside, and do not need to be composed of two parts.
