Description

【０００１】
【発明が属する技術分野】
本発明は、履物底に設け、導電性繊維によるコロナ放電を利用して、歩行時に履物と地面との間で発生する静電気を除去する履物底用静電気除去具、及び当該静電気除去機能を備えた履物底に関する。
【０００２】
【従来の技術】
従来より、履物本体の底で地面と接する部分を形成するゴム、繊維物等材料に、ステンレスファイバーの織度０．５デニール乃至１．５デニール、長さ０．０１乃至０．１５ｍｍの材料を重量比３乃至５％の範囲で含有した静電気防止履物、及び、前記ステンレスファイバーに代えてチップ状若しくは箔状ステンレスを使用した静電気防止履物（以下、先行技術１という。）が公知である（例えば、特許文献１参照。）。
【０００３】
【特許文献１】特開平２００２−１０１９０４（第２−３頁）
【０００４】
【発明が解決しようとする課題】
履物底は、地面と激しく擦れる部位であることから、歩行時において静電気発生の大きな原因となっている。この結果、履物底には、静電気が溜まり、更に、静電移動によって、人体全体が帯電することとなる。このような観点から、人体が帯電しないように、履物底において、除電できることが非常に望ましい。
【０００５】
しかしながら、上記先行技術１に係る発明は、前記したように、履物底における接地部位にステンレスファイバーは床面の材質に関わらず、導電性繊維の先端で静電気を中和減少により減衰させようとするものであるが、合成ゴム等と配合して、常に接地状態として使用するものであるため、地面との接触によって、導電性繊維の露出面が汚染されることで、放電が阻害される虞があった。
【０００６】
また、合成ゴム等にステンレスファイバーを配合する場合には、当該合成ゴムが本来有する耐久性、弾力性等と比較して、劣る可能性が非常に高く、履き心地や歩き易さといった点で質の低下を招来するものであった。
【０００７】
本発明は以上の事情に鑑みてなされたものであり、耐久性、弾力性といった履物底の材料の特性に影響を与えず、また、導電性繊維の露出面が汚染されることによる除電機能の低下を招来しない静電気除去具及び静電気除去履物底を提供することを、解決しようとする手段とするものである。
【０００８】
【課題を解決するための手段】
履物底の接地面に対する取付手段を内面に備えた基板と、コロナ放電を除電手段とする静電気除去シートとから構成され、基板における接地面に前記静電気除去シートの厚さよりも深い凹部を形成するとともに、該凹部の底面に対して、前記静電気除去シートを固着手段を介して取付けることにより、静電気除去シートの外面が、基板の接地面により凹んだ段差を形成した静電気除去具、及び、コロナ放電を除電手段とする静電気除去シートを、履物底における接地面において、前記静電気除去シートの厚さよりも深い凹部を形成し、凹部底面に対して、前記静電気除去シートを固着手段を介して取付けることにより、前記静電気除去シートの外面が、履物底の接地面より凹んだ段差を形成した静電気除去履物底等を、課題を解決するための手段とするものである。
【０００９】
【発明の効果】
本発明に係る履物底用静電気除去具によれば、上記したように、コロナ放電を除電手段とする静電気除去シートを、当該静電気除去シートの厚さよりも深い凹部における底面に対して取付けて、該静電気除去シートの外面が、基板の接地面より凹んだ構成としたことから、歩行時に生じて履物底に溜まった静電気を、効率よく、当該履物底に近接した静電気除去シートのコロナ放電によって中和することができ、良好な除電効果を得ることができる。
【００１０】
また、本発明に係る履物底用静電気除去具によれば、履物底の底面に対して当該静電気除去シートを取付けるだけで、簡単に静電気の除去を行うことができる。
【００１１】
上記構成に加えて、基板の凹部縁にシート被覆片を形成して、静電気除去シートの外面端部を被覆したことによって、静電気除去シートの不用意な脱落を防止するとともに、当該静電気除去シートを汚れ等から保護することができる。
【００１２】
更に、本発明に係る静電気除去履物底においても、上記底用静電気除去具と同様に、コロナ放電を除電手段とする静電気除去シートを、当該静電気除去シートの厚さよりも深い凹部における底面に対して取付けて、該静電気除去シートの外面が、基板の接地面より凹んだ構成としたことから、当該静電気除去シートの外面が接地することなく、歩行時に生ずる静電気を、コロナ放電によって、静電気を中和し、良好な除電効果を得ることができ、また、履物底の凹部縁面にシート被覆片を形成し、該シート被覆片によって静電気除去シートの外面端部を被覆した場合においては、当該静電気除去シートを汚れ等から保護することができる。
【００１３】
そして、当初から上記除電手段を備えた構成としていることから、根本的に除電手段が脱落する虞を招来しないものとすることができる。
【００１４】
【発明の実施の形態及び実施例】
図１は本発明の実施例１に係る履物底用静電気除去具の斜視図、図２は図１のＡ−Ａ線拡大断面図、図３は本発明の実施例２に係る履物底用静電気除去具における図２のＡ−Ａ線と同様の断面図、図４は実施例２に係る履物底用静電気除去具を履物底へ取付けた状態を示す縦断面図、図５は実施例１に係る履物底用静電気除去具を履物の底部に取付けた状態を示す斜視図、図６は本発明の実施例３に係る静電気除去履物底を示す履物の斜視図、図７は同実施例３に係る静電気除去履物底のＢ−Ｂ線拡大端面図、図８及び図９は本発明の他の実施例に係る静電気除去履物底を示す底面図、図１０は既成履物の履物底に対して静電気除去シートを取付けた状態を示す底面図、図１１は、既成履物における履物底に対して静電気除去シートを取付けた状態を示す、履物底のＣ−Ｃ拡大断面図である。
【００１５】
本発明の実施例１に係る履物底用静電気除去具は、図１、図２及び図５に示すように、主として長軸１０５ｍｍ、短軸６５ｍｍ程度の楕円に近似した、厚さ４ｍｍ程度の板状のウレタンゴムからなる基板１と、厚さｔが１．５ｍｍ程度の極細導電性繊維からなる不織布状の静電気除去シート２とから構成されるものである。
【００１６】
ここで、基板１には、図１に示すように、その接地面には、静電気除去シート２を嵌め込むための深さｍが２．５ｍｍ程度の凹部１１を三箇所に形成するとともに、接地面１０の裏面となる内面１３全体には、厚さ０．３ｍｍ程度の両面粘着テープ５と剥離紙６を順次積層したものとしている。この両面粘着テープ５は、履物底７に対する履物底用静電気除去具の取付手段としてはたらくものである。
【００１７】
また、図５に示すように、剥離紙６を剥がした三枚の静電気除去シート２を、基板１における三箇所の凹部１１の夫々の底面１２に、厚さ０．３ｍｍ程度の両面粘着テープ４１によって貼着している。これによって、該静電気除去シート２の外面２０が、基板１の接地面１０より凹んだ段差４０が形成されることとなり、基板１の接地面１０が地面に当接した状態において、静電気除去シート２は接地せず、該静電気除去シート２の外面２０と、地面との間に、空間が形成されることとなる。
【００１８】
そして、この段差４０が形成されることによって、着用時に静電気除去シート２が接地しないことから、導電性繊維の露出面が歩行時に汚染されることを防止することができる。
【００１９】
使用時において、歩行等により、履物底に静電気が溜まると、履物底は、静電気除去シートと非常に距離的に近い位置関係にあることから、該静電気除去シート２の外面２０から履物底へ向けて、コロナ放電が生じ、電気的に中和することで、静電気を除去することができるものである。
【００２０】
尚、本実施例１における静電気除去シート２としては、例えば、アクリル繊維の表面に硫化銅の皮膜で被覆した有機導電性繊維（商標名：サンダーロン）からなる不織布を使用することができる。
【００２１】
本発明の実施例２に係る履物底用静電気除去具は、図３及び図４の拡大断面図に示すように、基本構成、即ち、履物底３の接地面３０に対する取付手段として両面粘着テープ５を内面１３に備えた基板１と、極細導電性繊維からなる不織布状の静電気除去シート２とから構成され、基板１における接地面１０に前記静電気除去シート２の厚さｔよりも深い寸法ｍとした凹部１１を形成するとともに、該凹部１１の底面１２に対して、前記静電気除去シート２を両面粘着テープ４１を介して取付けて、該静電気除去シート２の外面２０が、基板１の接地面１０より凹んだ段差４０を形成した点については、実施例１と共通するものであり、基板１の凹部縁１４にシート被覆片１５を形成し、該シート被覆片１５によって静電気除去シート２の外面端部２１を被覆した点において、前記実施例１に係る履物底用静電気除去具と相違するものである。
【００２２】
そして、本実施例２によれば、基板１の凹部縁１４にシート被覆片１５を形成し、該シート被覆片１５によって静電気除去シート２の外面端部２１を被覆したことによって、静電気除去シート２の不用意な脱落を防止するとともに、当該静電気除去シート２を歩行時の汚れ等から保護することができるとともに、実施例１に係る履物底用静電気除去具と比べて、当該履物底用静電気除去具の接地面積を増加させることができ、地面に対するグリップ力をより一層良好とすることができる。
【００２３】
尚、上記実施例１及び実施例２に係る履物底用静電気除去具４と履物底７の接地面７０との取付手段において、両面粘着テープ５等の簡素で強力な接着手段を用いた場合には、当該両面粘着テープ５のみを交換することで、装着者の好みに応じて簡単に位置を変更することができる。
【００２４】
また、本発明の実施例３に係る静電気除去履物底３は、図６及び図７に示すように、実施例１及び実施例２に係る履物底用静電気除去具４と同様の、アクリル繊維の表面に硫化銅の被膜で被覆した有機導電性繊維（商標名：サンダーロン）からなる不織布を静電気除去シート２として使用したものであり、当該静電気除去履物底３の接地面３０に、前記静電気除去シート２の１．５ｍｍの厚さより深い２．５ｍｍの深さ寸法の凹部３１を、三箇所形成し、該凹部３１内の底面３２に対して、前記静電気除去シート２を、両面粘着テープ３３によって取付けることにより、前記静電気除去シート２の外面２０が、履物底３の接地面３０より凹んだ段差３４を形成し、前記実施例２と同様の手法により、静電気防止履物底３の凹部縁３５にシート被覆片３６を形成し、該シート被覆片３６によって静電気除去シート２の外面端部２１を被覆した構成としたものである。
【００２５】
即ち、本実施例３における静電気除去履物底３においては、実施例１及び実施例２に係る履物底用静電気除去具４と同様の機能を具備させることにより、コロナ放電による静電気の中和、除電能を確保することができるとともに、予め履物底として形成することで、除電手段が脱落する虞がなく、更に、耐久性を得ることができるものである。
【００２６】
また、本発明の履物底用静電気除去具及び静電気除去履物底における凹部の配置は、実施例１乃至実施例３に示した三箇所に凹部を有するもののみに限定されるものではなく、図８、図９に示すように、例えば、多数の円形の凹部や複数の帯状の凹部等とすることもできる。
【００２７】
更に、本発明においては、図１０に示すように、既成の履物における履物底８の接地面８０に予め形成された溝８１に対して、該溝８１の深さよりも薄い、コロナ放電を除電手段とする静電気除去シート（２）を該溝８１に嵌合する大きさにカットして取付け、接地面よりも静電気除去シート２の外面２０が凹んだ状態とすることによって、履物底８の除電を行うこともできる。
【００２８】
以上のように、本発明においては、コロナ放電を除電手段とする静電気除去シートとして、アクリル繊維の表面に硫化銅の被膜で被覆した有機導電性繊維（商標名：サンダーロン）からなる不織布を使用したが、必ずしもこれに限られるものではなく、例えばポリエチレンテレフタレート綿、パルプ、カーボンを基材として導電性物質を混合した導電性繊維（商標名：ソルディオン）や炭素繊維等のように、コロナ放電による除電効果を得ることができる繊維であればよいとする趣旨である。
【００２９】
そして、これらいずれの繊維を使用した場合であっても、本発明の特徴とする構成、即ち、履物底７の接地面７０に対する取付手段を内面１３に備えた基板１と、コロナ放電を除電手段とする静電気除去シート２とから構成され、基板１における接地面１０に前記静電気除去シートの厚さよりも深い凹部１１を形成するとともに、該凹部１１の底面１２に対して、前記静電気除去シート２を固着手段を介して取付けることにより、静電気除去シート２の外面２０が、基板１の接地面１０よりも凹んだ段差を形成した構成、若しくは、コロナ放電を除電手段とする静電気除去シート２を、履物底３における接地面において、前記静電気除去シート２の厚さよりも深い凹部３１を形成し、該凹部３１の底面３２に対して、前記静電気除去シート２を固着手段を介して取付けることにより、前記静電気除去シート２の外面２０が、履物底３の接地面３０より凹んだ段差３４を形成した構成によって、若しくは、履物底８の接地面８０に予め形成された溝８１に対して、該溝８１の深さよりも薄い、コロナ放電を除電手段とする静電気除去シート（２）を取付けて、接地面よりも静電気除去シート２の外面２０が凹んだ状態とすることによって、静電気除去シート２は接地しないことからその硬さの程度に関係なく、履き心地に悪影響を与えることもなく、また、当該静電気除去シートが汚染、磨耗することもなく、履物底の近傍に空間を形成して静電気除去シートが配置される構成により、コロナ放電を効率良く行うことができるという非常に優れた効果を生ずるものである。

TECHNICAL FIELD OF THE INVENTION
The present invention includes a footwear sole static eliminator that is provided on a shoe sole and removes static electricity generated between the shoe and the ground during walking using corona discharge by conductive fibers, and the static elimination function. Related to footwear soles.
[0002]
[Prior art]
Conventionally, a material having a weave of 0.5 denier to 1.5 denier and a length of 0.01 to 0.15 mm of stainless steel fiber is used for a material such as a rubber or a fiber material forming a portion in contact with the ground at the bottom of the footwear body. Antistatic footwear containing a weight ratio of 3 to 5% and antistatic footwear using chip-shaped or foil-shaped stainless steel in place of the stainless steel fiber (hereinafter referred to as prior art 1) are known (for example, see Related Art 1). And Patent Document 1.).
[0003]
[Patent Document 1] JP-A-2002-101904 (pages 2-3)
[0004]
[Problems to be solved by the invention]
Since the sole of the footwear rubs violently against the ground, it is a major cause of static electricity generation during walking. As a result, static electricity accumulates on the sole of the shoe, and the entire human body is charged by the electrostatic movement. From such a viewpoint, it is highly desirable to be able to remove static electricity at the sole of the footwear so that the human body is not charged.
[0005]
However, in the invention according to the prior art 1, as described above, the stainless fiber is used to attenuate the static electricity at the tip of the conductive fiber by the neutralization reduction, regardless of the material of the floor surface, in the ground portion of the footwear sole. However, since it is always used as a grounded state by blending it with synthetic rubber or the like, there is a risk that the contact with the ground will contaminate the exposed surface of the conductive fiber, thereby impeding discharge. there were.
[0006]
Also, when stainless fiber is blended with synthetic rubber or the like, there is a very high possibility that the synthetic rubber is inferior to the inherent durability, elasticity, etc. of the synthetic rubber, and the quality is low in terms of comfort and ease of walking. Was caused.
[0007]
The present invention has been made in view of the above circumstances, does not affect the characteristics of the material of the shoe sole such as durability and elasticity, and has a static elimination function due to contamination of the exposed surface of the conductive fiber. An object of the present invention is to provide a static eliminator and a footwear sole that does not cause deterioration.
[0008]
[Means for Solving the Problems]
A substrate provided on the inner surface with means for attaching to the grounding surface of the sole of the footwear, and a static elimination sheet using corona discharge as a static elimination means, and a concave portion deeper than the thickness of the static elimination sheet is formed on the grounding surface of the substrate. By attaching the static elimination sheet to the bottom surface of the concave portion via fixing means, the outer surface of the static elimination sheet is formed with a step recessed by the ground surface of the substrate. By forming a recess deeper than the thickness of the static elimination sheet on the grounding surface of the footwear, and attaching the static elimination sheet to the bottom of the recess through fixing means, The outer surface of the static elimination sheet has a step formed from the ground contact surface of the sole of the shoe, and the static elimination shoe sole has a stepped portion. It is an stage.
[0009]
【The invention's effect】
According to the footwear sole static eliminator according to the present invention, as described above, the static eliminator sheet using corona discharge as the static eliminator is attached to the bottom surface of the concave portion deeper than the thickness of the static eliminator sheet. The outer surface of the static elimination sheet is recessed from the ground surface of the board, so static electricity generated during walking and accumulated on the sole of the footwear is efficiently neutralized by corona discharge of the static elimination sheet near the bottom of the footwear. And a good static elimination effect can be obtained.
[0010]
In addition, according to the footwear sole static eliminator according to the present invention, static elimination can be easily performed simply by attaching the static elimination sheet to the bottom surface of the shoe sole.
[0011]
In addition to the above configuration, by forming a sheet covering piece on the edge of the concave portion of the substrate and covering the outer surface end of the static electricity removing sheet, it is possible to prevent the static electricity removing sheet from accidentally falling off and to remove the static electricity removing sheet. It can be protected from dirt and the like.
[0012]
Furthermore, also in the static electricity removing shoe sole according to the present invention, similarly to the above-described static electricity removing device for a sole, the static electricity removing sheet using corona discharge as the electricity removing means is placed on the bottom surface of the concave portion deeper than the thickness of the static electricity removing sheet. Since the outer surface of the static electricity removing sheet is recessed from the grounding surface of the substrate after mounting, the static electricity generated during walking is neutralized by corona discharge without the outer surface of the static electricity removing sheet being grounded. In addition, a good static electricity removing effect can be obtained, and when a sheet covering piece is formed on the edge surface of the concave portion of the footwear sole and the outer surface end of the static electricity removing sheet is covered with the sheet covering piece, the static electricity removing effect can be obtained. The sheet can be protected from dirt and the like.
[0013]
And since it was set as the structure provided with the said static elimination means from the beginning, it can be set as what does not cause the possibility that a static elimination means will fall fundamentally.
[0014]
