[Detailed description of the device]

[Industrial applications]

 The present invention, for example, when opening and closing the door of a car, in order to prevent the static electricity charged to the human body from being discharged between the door and the discomfort, it is attached to the door and its surroundings to release the static electricity by touching it beforehand. The present invention relates to an antistatic plate.

[0002]

[Prior art]

 For example, when a passenger touches a door while getting in or out of a car, he or she often receives an electric shock due to static electricity and feels uncomfortable. During operation, the seat and the clothes are in contact with each other and electrically neutralized. However, a large amount of static electricity is generated when clothes are removed from the seat sheet when getting off, and the generated static electricity is charged to the human body. The electrostatic charge on the human body is extremely high due to this static electricity.For example, when a metal door or door knob is touched, the electric charge on the human body is discharged at once, and the user feels uncomfortable due to the electric shock caused by the discharge. .

Conventionally, in order to prevent the discomfort caused by static electricity, there has been an electrostatic prevention plate 21 as shown in FIG. 5 in which the electric charge charged to the human body is gradually released by touching in advance to avoid the discomfort caused by discharge. . As shown in FIG. 5, the antistatic plate 21 includes a conductive resin plate 22, a terminal 23, and a double-sided tape 24. The conductive resin plate 22 has a resistance of about several tens to several hundreds MΩ and is made of a conductive resin formed in a thin plate having a square plate shape, and a recess having a size corresponding to the terminal 23 is formed on the back surface thereof. ing. The terminal 23 has a thickness of 0. It is made of a stainless steel plate of about 3 mm, and its surface is plated. The ground wiring 25 is joined to one end of the terminal 23 by soldering. The terminal 23 is fitted into a recess formed on the back surface of the conductive resin plate 22, and the conductive resin plate 22 and the double-sided adhesive tape 24 are integrally fixed with the terminal 23 sandwiched therebetween.

The antistatic plate 21 is attached to a place that is easily touched by a person when getting on and off a door of an automobile, for example, due to the adhesive force of the double-sided adhesive tape 24 provided on the back side thereof. The grounding wiring 25 drawn out from the terminal 23 is connected to the body of the vehicle and grounded. By touching the conductive resin plate 22 of the antistatic plate 21 when getting on and off the vehicle, the terminal 23 and the ground wiring 25 are connected through the conductive resin plate 22 having a high resistance to the electric charge charged on the human body. Since it gradually escapes to the body through it, the person does not feel uncomfortable due to the discharge of the charged electric charge.

[0005]

[Problems to be solved by the device]

 By the way, as described above, it is preferable to attach the antistatic plate 21 to a place such as a door where a person can easily touch it naturally. However, the place where a person can naturally touch is not always a flat surface. For example, the door trim provided on the passenger compartment side of an automobile door is not necessarily formed on a flat surface, and especially when the antistatic plate 21 is attached to a door grip that is easily touched by people. The surface becomes a curved surface.

However, as described above, since the terminal 23 of the antistatic plate 21 is made of a stainless steel plate having a thickness of about 0.3 mm, it is hard to be deformed flexibly and adhered closely to the curved surface of the door grip or the like. I couldn't attach it. As a result, the adhesive area cannot be secured sufficiently and there is a risk of peeling off over a long period of time. Further, even if it is adhered once in a close contact state, there is a problem that it is easily peeled off because the rigid stainless plate has a strong restoring force to return to the initial shape.

As an example in which the antistatic plate can be deformed according to the surface shape of the pasting surface, Japanese Patent Laid-Open No. 61-85798 discloses a terminal made of metal wire as shown in FIGS. 6 (a) and 6 (b). The antistatic plate 26 shown in is proposed. As shown in FIGS. 6A and 6B, the antistatic plate 26 includes a contact plate 27 made of a synthetic resin having a high resistance, and a single stainless steel plate having a spring characteristic bent in a substantially U shape. It is composed of a metal wire 28 such as a wire and a double-sided adhesive tape 29.

As shown in FIG. 6A, the antistatic plate 26 is provided in the vicinity of the key cylinder 31 provided on the door 30 of the automobile, and the metal wire 28 is provided at the end of the key cylinder 31 due to its spring characteristic. It is attached via a double-sided adhesive tape 29 in a pressed state. However, since the metal wire 28 has a spring characteristic and has a certain degree of rigidity, the antistatic plate 26 easily bends in its width direction, but it is difficult to bend it in its longitudinal direction. Therefore, it was not suitable enough for sticking to a curved surface with a relatively complicated shape such as a door grip.

The present invention has been made to solve the above problems, and the purpose thereof is to attach an antistatic plate even if the attachment surface is not a flat surface but a curved surface or an undulating surface. It is to provide an antistatic plate that can be reliably attached to the attachment surface.

[0010]

[Means for Solving the Problems]

 In order to solve the above problems, the device according to claim 1 has an electrostatic shock absorbing member made of a conductive material having a high resistance and having a high resistance to the extent that the static electricity on the human body can be gradually released. An antistatic plate including a grounded electrode member that is in electrical contact with the static electricity buffer member, and a flexible adhesive member that is fixed to the back surface side of the static electricity buffer member with the electrode member interposed therebetween. In the above, the electrode member was constituted by a film-shaped resin substrate on which a conductive film made of metal was formed.

According to the second aspect of the invention, a groove-like cut is formed on the surface of the electrostatic shock absorbing member. Further, in the invention according to claim 3, the electrode member is formed in a comb tooth shape.

[0012]

[Action]

 With the above structure, according to the invention of claim 1, the static electricity buffering member is made of a flexible conductive material having a high resistance to the extent that static electricity on the human body can be gradually released. Is a film-shaped resin substrate forming a conductive film made of metal. Then, a flexible adhesive member is fixed to the back surface side of the static electricity buffering member while sandwiching the electrode member to form an antistatic plate. That is, the antistatic plate is configured by sandwiching a film-shaped resin substrate forming a conductive film between a flexible electrostatic buffer member and a flexible adhesive member. As a result, the antistatic plate itself is provided with flexibility. The antistatic plate is attached to a place easily accessible by a person, such as an automobile door, via an adhesive member on the back surface thereof.

At that time, even if the sticking surface is a curved surface or an undulating surface, the flexible antistatic plate is deformed flexibly so as to be in close contact with the sticking surface, so that the bonding area is sufficient. It is secured to and is strongly adhered to the pasting surface. Further, since the antistatic plate once adhered to the pasting surface has flexibility, the restoring force for returning to the initial shape is relatively weak and cannot be easily peeled off. As a result, the once-adhered antistatic plate is not peeled off from the attachment surface due to the attachment surface being curved or undulating, and the initial attachment state is maintained for a long period of time.

Further, according to the second aspect of the invention, when the antistatic plate is bonded to the attachment surface such as the curved surface or the undulating surface by the groove-shaped notch formed on the surface of the static electricity buffering member. Moreover, the antistatic plate is deformed more flexibly according to the shape of the attachment surface. As a result, compared with the case where no groove-like cut is formed on the surface of the static electricity buffering member, the adhesion to the pasting surface is further improved, and the restoring force for returning to the initial shape is further reduced. The antistatic plate becomes even more difficult to peel off.

Further, according to the invention as set forth in claim 3, since the electrode member is formed in a comb-teeth shape, it is possible to bring the electrode member into contact with the entire surface of the static electricity buffering member evenly. Become. Further, since the electrode member is formed in a comb shape, the electrode member is flexibly deformed with respect to the stress applied from the outside. As a result, the stress applied to the electrode member when the antistatic plate is deformed is relieved by the flexible deformation of the electrode member, so that the electrode member is not damaged. Further, since the adhesive member is brought into contact with the static electricity buffering member via the comb-teeth gap of the electrode member, the adhesive area between the static electricity buffering member and the electrode member is sufficiently secured.

【Example】

 An embodiment embodying the present invention will be described below with reference to FIGS. As shown in FIG. 1, the antistatic plate 1 is composed of a conductive resin plate 2, a flexible substrate 3 and a double-sided adhesive tape 4. The flexible conductive resin plate 2 formed into a thin plate having a substantially square plate has a resistance of about several tens to several hundreds MΩ, and a plurality of groove-shaped notches 2a running vertically and horizontally are formed on the surface thereof. Has been done. The conductive resin plate 2 is made of conductive rubber or plastic, and is formed, for example, by mixing conductive powder such as carbon with rubber or plastic. Further, a concave portion 2b (shown in FIG. 2) having a size corresponding to the flexible substrate 3 is formed on the back surface of the conductive resin plate 2. As shown in FIGS. 2 and 3, the flexible board 3 is made of a resin board 3b in the form of a film having a thickness of about 0.1 mm and a terminal wiring 3a made of copper foil formed on the surface thereof. It is shaped like a comb that draws the crank. Copper is preferably used for the terminal wiring 3a from the viewpoint of conductivity and cost, but other metals such as aluminum, silver, gold and nickel can also be used.

Further, among the notches 2 a, the notches 2 a running in the width direction (direction orthogonal to the longitudinal direction) of the conductive resin plate 2 are formed at positions corresponding to the gaps of the comb-shaped flexible substrate 3. . As shown in FIG. 1, the first end of the ground wire 5 is soldered to one end of the terminal wire 3a. The terminal wiring 3a and the ground wiring 5 may be joined to each other by a method other than soldering such as caulking or welding.

As shown in FIG. 2, the flexible substrate 3 is fitted into the recess 2 b formed on the back surface of the conductive resin plate 2, and in this state, one side of the double-sided adhesive tape 4 is attached to the back surface of the conductive resin plate 2. Are glued together. In this way, the flexible substrate 3 is held in the recessed portion 2b of the conductive resin plate 2 so that the terminal wiring 3a formed on the resin substrate 3b is in electrical contact with the conductive resin plate 2. Is held. 2 and 3, the thickness of the flexible substrate 3 is exaggerated, and the flexible substrate 3 is in pressure contact with the back surface of the conductive resin plate 2.

Next, the operation of the antistatic plate 1 configured as described above will be described. The antistatic plate 1 is provided with a double-sided adhesive tape 4 provided on the back surface of the antistatic plate 1 on the outside of the door trim 7 and the door 6 installed inside the door 6 of the vehicle shown in FIG. It is used by pasting it on the side surface. In this embodiment, the antistatic plate 1 is used by being attached to the grip 7a integrally formed with the door trim 7.

As shown in FIG. 4, the grip 7a that a person naturally grips when getting off from an automobile is not formed into a flat surface with a uniform surface shape, but is usually formed into a curved or undulating surface shape. There is. For example, when the antistatic plate 1 is attached to the curved portion of the grip 7a as shown in FIG. 4, the antistatic plate 1 needs to be deformed along the curved surface of the grip 7a.

According to the antistatic plate 1 of the present embodiment, the flexible substrate sandwiched between the conductive resin plate 2 made of a flexible thin plate having a substantially rectangular plate shape and the double-sided adhesive tape 4. Reference numeral 3 is a film-shaped resin substrate 3b having a copper foil terminal wiring 3a on its surface. That is, since the conductive resin plate 2, the flexible substrate 3, and the double-sided adhesive tape 4 are all flexible, the electrostatic protection plate 1 composed of them is also flexible. Therefore, since the flexible substrate 3 is deformed flexibly with respect to the stress applied from the outside, the flexible substrate 3 is also flexibly deformed along the curved surface of the grip 7a when it is attached to the curved surface of the grip 7a.

Further, since the flexible substrate 3 is continuously formed in a comb-like shape that draws a plurality of cranks, the flexible substrate 3 is flexibly deformed especially against bending and twisting in the longitudinal direction of the antistatic plate 1. . Further, since the groove 2a running in the vertical and horizontal directions is formed on the surface of the conductive resin plate 2, the groove 2a may be closed or opened as the antistatic plate 1 is deformed, so that The antistatic plate 1 deforms more flexibly. As a result, the antistatic plate 1 can be brought into close contact with the curved portion of the grip 7a. Further, it is possible to secure a sufficient adhesive area between the double-sided adhesive tape 4 provided on the back surface of the antistatic plate 1 and the curved portion of the grip 7a.

Here, since the notch 2a formed on the surface of the conductive resin plate 2 is not a mere notch but is formed in a groove shape, the antistatic plate 1 is formed on the convex sticking surface. In addition to being able to flexibly deform, it is also possible to flexibly deform to the concave attachment surface. Therefore, the antistatic plate 1 can secure a sufficient adhesion area with respect to the attachment surface regardless of whether the attachment surface is convex or concave.

The antistatic plate 1 thus attached to the curved surface of the grip 7a is held in a curved state along the curved surface of the grip 7a. The force to restore the shape works. However, since the antistatic plate 1 has a characteristic of being easily deformed flexibly, the restoring force for returning to the initial shape is also very weak, and therefore the antistatic plate 1 once attached has a bent attachment surface. It is unlikely that it will peel off. As a result, the static prevention plate 1 that has been once attached is held in the initial state where it is strongly adhered for a long period of time even if the attachment surface is a curved surface or an undulating surface. Therefore, even if the antistatic plate 1 attached to the curved portion of the grip 7a is touched each time the vehicle gets off, the antistatic plate 1 is strongly adhered and the restoring force for returning to the initial shape is extremely high. Since it is weak against touching, it does not come off due to repeated touching. The grounding wire 5 is passed through the door 6 and grounded to the metal part inside the door 6 at its second end.

The antistatic plate 1 attached to the grip 7a of the door trim 7 of the door 6 in this manner is touched by, for example, a driver every time the vehicle gets off the vehicle. The driver naturally touches the antistatic plate 1 when gripping the grip 7a to get off the vehicle, and when the driver leaves the seat while gripping the grip 7a, static electricity is generated in the process of the clothes separating from the seat. However, the electric charge due to the static electricity is gradually released through the antistatic plate 1 touched by the driver. As a result, the driver does not feel uncomfortable due to static electricity even if he / she touches the metal part such as the door 6 after getting off the vehicle.

As described above in detail, according to this embodiment, the film-shaped resin substrate 3b having the terminal wiring 3a of the copper foil provided on the surface is used as the conductive resin resin in the shape of a substantially rectangular plate having flexibility. The antistatic plate 1 was constructed by sandwiching and adhering between the rate 2 and the double-sided adhesive tape 4. That is, the antistatic plate 1 was made flexible by providing the antistatic plate 1 only with a flexible member. As a result, even if the sticking surface is a curved surface or an undulating surface, the antistatic plate 1 is flexibly deformed so as to be in close contact with the sticking surface, so that a sufficient bonding area can be secured. .

Further, since the groove-shaped cut 2a running in the vertical and horizontal directions is formed on the surface of the conductive resin plate 2, the antistatic plate 1 can be more flexibly deformed by the cut 2a. Since the cut 2a is formed in the shape of a groove having a width instead of a simple cut, the antistatic plate 1 is flexibly deformed not only to warp to the back surface side but also to warp to the front surface side. Therefore, regardless of whether the attachment surface is convex or concave, a sufficient adhesion area can be secured and the antistatic plate 1 can be reliably adhered. Further, since the notch 2a running in the width direction of the conductive resin plate 2 is formed at the position corresponding to the comb tooth gap of the flexible substrate 3, even if the stress is concentrated at the position corresponding to the notch 2a, the flexible substrate 3 and thus the terminal wiring. Does not damage 3a. Further, the groove-shaped cuts 2a running in the vertical and horizontal directions formed on the surface of the antistatic plate 1 can impart a design effect to the antistatic plate 1.

Furthermore, since the flexible substrate 3 is formed in a comb-like shape that draws a plurality of continuous cranks, the terminal wiring 3a can be contacted evenly over the entire surface of the conductive resin plate 2. Further, the comb-like shape allows the flexible substrate 3 to be more flexibly deformed, and in particular, the flexibility of the antistatic plate 1 with respect to bending and twisting in the longitudinal direction is enhanced. Therefore, the antistatic plate 1 can be deformed more flexibly, and even if the antistatic plate 1 is deformed, the flexible substrate 3 is not damaged and its life can be extended. Further, since the flexible substrate 3 has a comb-teeth shape, the adhesive area between the conductive resin plate 2 and the double-sided adhesive tape 4 can be secured by interposing the interstices between the comb-teeth.

The present invention is not limited to the above-described embodiment, but may be configured as follows, for example, within the scope of the invention. (1) In the above embodiment, the cut 2a is formed so as to run vertically and horizontally, but the cut 2a may be formed so as to draw a specific design.

(2) The attachment place of the antistatic plate 1 can be changed appropriately. For example, it may be attached to the outer surface of the door 6 like the antistatic plate disclosed in Japanese Patent Laid-Open No. 61-85798 described in the prior art. In this case, when the door is opened to get into the vehicle or when the vehicle is dismounted from the vehicle and the door is closed, touching the antistatic plate 1 attached to the outer surface of the door 6 causes discomfort due to static electricity. Evaded from. Further, the antistatic plate 1 may be attached to an appropriate place other than the door opener and its periphery, or the grip 7a of the door trim 7.

(3) The adhesive member is not limited to the double-sided adhesive tape 4. For example, the adhesive member may be a one-sided adhesive tape, and an adhesive may be used for adhesion on the other one side having no adhesive force. Further, the adhesive member may be composed of a tape having no tackiness and an adhesive. Alternatively, the adhesive member may be a resin tape or the like having magnetic force, and the antistatic plate 1 may be magnetically attached to a metal portion of the door 6 or the like.

(4) The number of the antistatic plate 1 to be attached to the automobile is not limited to one, and it may be plural. In particular, it is more suitable to be able to touch the vehicle when getting on and off the vehicle. Further, the antistatic plate 1 may be attached to each door.

(5) The shape of the flexible substrate 3 is not limited to the comb tooth shape. For example, the shape may be a substantially square plate. Even in this case, since the thickness of the flexible substrate 3 is as thin as about 0.1 mm, the antistatic plate 1 is flexibly deformed regardless of its shape.

(6) The antistatic plate of the present invention is not limited to an automobile, but can be widely used for avoiding discomfort caused by electrostatic discharge. For example, the antistatic plate of the present invention may be attached to the door of a room in a building and used.
