【発明の属する技術分野】
本発明はスタッド材の取付方法に関し、例えば複写機等の事務用機器、各種の小型機械等にてモータからの回転力を伝達する歯車、スプロケット、ローラ、プーリ等の動力伝達部品を支持するためのスタッド材を基板に容易かつ確実に取り付けるのに最適であり、しかもリサイクルを可能になす。
【0002】
【従来の技術】
従来、例えば複写機、印刷機等の事務用機械においてモータからの回転力を伝達するための歯車、スプッロケット、ローラ、プーリ等の動力伝達部品はスタッド材に支持されていた。このスタッド材をプレス機により打抜かれた基板に取付けるための取付方法には図1に示すものがあった。
すなわち被取付体としての基板aに設けられた正面略正円形の取付孔b内にスタッド材cの取付側の基端部に形成した取付部dを挿入して取付部dをかしめ固定し、スタッド材cの基端側に形成した基板aの一側面に接触する拡大鍔部eとかしめ固定部d1 とにより基板aを挟持することにより所望個数のスタッド材cを基板aに取付けるものである。
【0003】
【発明が解決しようとする課題】
しかしながら、図1に示すようにかしめ固定法により基板aにスタッド材cを取付ける上記従来の取付方法は、基板aにスタッド材cを取付けるのに基板aに対するスタッド材cの位置決め精度が低く、しかもスタッド材cの取付けには多くの時間と手間を必要としていた。また、かしめ固定法によりスタッド材cを基板aに取付けるための上記従来の方法は、スタッド材cに設けられる取付孔bはスタッド材cの外径φ′に応じた専用の大きさの取付孔bを基板aに設けなければスタッド材cを基板aに取付けることができないので、スタッド材cが磨耗したり、破損する等して交換を必要とする場合には、基板a毎全てのスタッド材cを交換しなければならなかった。しかも基板aに取付けられるスタッド材cはその外径φ′が1種類のものに限って基板aに取付けられるのに限らず、大小種々の外径φ′のスタッド材cが用意され、基板aにはスタッド材cの外径φ′に応じた大小異径の取付孔bを設けることにより基板aに異なる外径のスタッド材cを取付ける。この場合、スタッドcのかしめ代としてのかしめ固定部d1 もスタッド材cの外径φ′の大小に応じて基板aの後面に露出される。
またスタッド材cは、交換後の古い基板aおよびスタッド材cは再利用に供されることなく廃棄されていた。従って、資源活用の面から有効利用が行えずに不経済であった。
また、かしめ固定により基板aに取付けられる上記従来の方法は、経時の使用により基板aに対してスタッド材cが回転し、緩みを生じたり、がたつきを生ずるので、歯車等の動力伝達部品も磨耗等の損傷を助長することになる。
【0004】
本発明は上記従来の不都合を解決し、基板にスタッド材を高い精度で位置決めして迅速かつ確実に取付け、またスタッド材に磨耗や破損を生じて交換を必要とする場合に所望個所、所望本数のスタッド材のみの取付が行え、ほかのスタッド材と基板とは廃棄されることなく再利用に供して資源活用が有効に行え、またスタッド材が経時の使用により緩みやがたつきを生ずることなく構造的に堅牢な取付が行え、耐命性が向上するスタッド材の取付方法を提供しようとする。
【0005】
【課題を解決するための手段】
本発明の請求項1は、スタッド材の一側の基端に形成される取付部の係合壁面部を被取付体に設けた平面略長円形もしくは平面略多角形をなす取付孔の短軸方向に位置する直線状の内側面に係合させてスタッド材の回動を規制し、取付ねじをスタッド材の取付部に設けた雌ねじ孔内に螺入してスタッド材に設けた拡大鍔部と前記取付ねじの周縁に、ばね性を発揮させるように逆皿状に形成された鍔部とにより被取付体をばね性にて挟持、固定してスタッド材を被取付体に取付けることを特徴する。
【0006】
また、本発明の請求項2の発明は、請求項1において、被取付体に設けられる取付孔を所望複数個所望配列にて設け、該取付孔内に取付部が挿入される複数個のスタッド材を一括して被取付体に対して着脱可能に取付けることを特徴とする。
【0007】
また、本発明の請求項3の発明は請求項1または2において、所望本数のスタッド材を略水平面上の所定位置に同方向に倒立して配置し、スタッド材に対して被取付体を上方から載置することによりスタッド材の基端部を被取付体に設けた取付孔に合致して挿入し、スタッド材の取付部に設けた雌ねじ孔内に取付ねじを螺入することにより被取付体にスタッド材を取付けることを特徴とする。
【0009】
【発明の実施の形態】
以下、本発明の実施の形態を図面を参照して説明する。
図1において1は取付孔1aが設けられた被取付体であり、この被取付体1としては例えば複写機、印刷機等の事務用機器、各種の小型機械等の基板2がある。この基板2はプレス機により打抜成形される。
【0010】
被取付体に設けられる取付孔1aは、図8に示すように小判形、楕円形等の平面略長円形もしくは図には示さないが平面略長多角形に形成され、幅方向すなわち短軸方向Yには後記スタッド材3の取付部3bが係入可能となることにより基板2に対するスタッド材3の取付時の位置決めと不用意な回動を規制するための直線状の内側面1a1 ,1a1 が左右対向して位置する。またこの取付孔1aは図8に示すように被取付体としての基板2に所望複数個が所望配列、図8では上段に2列、下段に3列が設けられているが、その配列および設置個数は例示であり図に示すもの限らず取付けるべきスタッド材3の外径φの大小、長さlにかかわらず、短軸方向Yの設置幅Tはスタッド材3の取付部3bが挿入されるように取付部3bの幅よりも僅かに大きい共用化された任意のものが選択される。すなわち、基板2に設けられる取付孔1aは短軸方向Yの設置幅Tが全て同一の幅のものを用いれば、例えばスタッド材3の外径φおよび長さlは全て同一のものを使用して基板2に取付けてもよいし、或いは外径φが大小異なったり、長さlが長短異なるスタッド材3を基板2に取付けることもできる。
【0011】
3は被取付体1に一端が取付けられるスタッド材であり、このスタッド材3には基端部側に被取付体1の一側面に接触する拡大鍔部3aを設け、該拡大鍔部3aに隣接する外端には前記取付孔1aに係入可能な係合壁面部3b1 ,3b1 を左右の側面に有する取付部3bを形成している。3cはスタッド材3の他端、すなわち図1の先端側の周面に設けられた溝であり、この溝3c内にCリング4を嵌着することによりモータからの回転力を伝達する歯車、スプロケット、ローラ、プーリ等の動力伝達部品はスタッド材3に支持される。3dはスタッド材3の取付部3b内に設けられた雌ねじ孔であり、この雌ねじ孔3d内に後記取付ねじ5が螺入される。
【0012】
5はスタッド材3の取付部3bに設けた雌ねじ孔3d内に螺入される取付ねじであり、この取付ねじ5は金属により形成され、周縁には鍔部5aが形成される。また、前記鍔部5aは使用時にスタッド材3の雌ねじ孔3dに螺入される時に受ける内部応力が経験され、該応力が経験されたまま熱処理を施こしたことによりばね性を発揮するように略逆皿状に形成されてスタッド材3に緩みが生ずることなく確実に固定がはかれる。
そして、スタッド材3の取付部3bに螺入される取付ねじ5の周縁に設けた鍔部5aとスタッド材3に設けられる拡大鍔部3aとにより被取付体としての基板2をばね性にて挟持、固定する。
【0013】
本発明の実施の態様の一例は以上の構成からなり、以下スタッド材3の取付方法について工程順に説明する。
【0014】
被取付体として例えば複写機、印刷機等の事務用機器、各種の小型機械等の基板2にスタッド材3を取付けるには、スタッド材3の基端に形成される取付部3bを被取付体1に設けた取付孔1a内に挿入する。
【0015】
この際、スタッド材3の一側の基端に形成される取付部3bの係合壁面部3b1 ,3b1 が図8に示すように被取付体に設けた平面略長円形もしくは平面略多角形をなす取付孔1aの短軸方向Yに位置する直線状の内側面1a1 ,1a1 に係合されるので、スタッド材3の取付時の位置決めと不用意な回動は規制される。
【0016】
また、複数個のスタッド材3を被取付体1としての基板2に取付けるのには、基板2に設けた複数個の取付孔1a内にスタッド材3の取付部3bを挿入する。
【0017】
複数個のスタッド材3の取付部3bを被取付体としての基板2に所望複数個、所望配列、例えば図8に示すように上段に2列、下段に3列の取付孔1aが設けられれば、この取付孔1aにスタッド材3の取付部3bが挿入されることにより取付位置の位置決めがなされる。
【0018】
この際、基板2に取付けるべきスタッド材3の配列、取付位置は基板2に設けられる取付孔1aの設置個数に対応して任意に設定される。しかも基板2に設けられる取付孔1aは、短軸方向Yの設置幅Tがスタッド材3の取付部3bが挿入されるように取付部3bの幅tよりも僅かに大きい任意のものが設けられて共用化がはかられるので、取付けるべきスタッド材3の外径φおよび長さlは全て同一のスタッド材3はもとより全て同一のスタッド材3ではなく外径φが大小異なったり長さlが長短異なるスタッド材3相互も基板2に取付けることができる。
【0019】
そして、取付ねじ5をスタッド材3の取付部3bに設けた雌ねじ孔3d内に螺入すると、基板2に設けられる取付孔1aは、図8に示すように小判形、楕円形等の平面長円形もしくは図には示さないが平面多角形に形成され、幅方向、すなわち短軸方向Yに対向して配置される直線状の内側面1a1 ,1a1 にスタッド材3の取付部3bの左右に設けた係合壁面部3b1 ,3b1 が係合するので、スパナ等の工具を用いてスタッド材3の回動を規制しながらドライバーにて取付ねじ5を回動操作しなくてもスタッド材3は不用意な回動が規制され、取付ねじ5をドライバーにより回動操作することにより取付孔3d内に取付ねじ5を迅速かつ確実に螺入することができる。しかも、スタッド材3は基板2に取付けられた後は、前述のように直線状の内側面1a1 ,1a1 に取付部3bの左右の係合壁面部3b1 ,3b1 が係合することによりスタッド材3の取付部3bが基板2の取付孔1a内に係合して緩みや不用意ながたつきが防止される。
【0020】
こうしてスタッド材3に設けた拡大鍔部3aと前記取付ねじ5の周縁に設けられる鍔部5aとにより被取付体1の基板2を前後から挟持、固定することによりスタッド材3を被取付体1に取付けることができる。
【0021】
また取付ねじ5は、周縁に設けられる鍔部5aが被取付体1に対する取付ねじ5の締付時と同様の変形を外力により与えて使用時に受ける内部応力が経験され、前記外力を解除してから一部の応力が残留された状態にて熱処理を施した歪時効処理によりばね性を発揮する略逆皿状に形成されるので、スタッド材3に設けた雌ねじ孔3d内に取付ねじ5を螺入することにより取付ねじ5の周面に設けた鍔部5aが高ばね性を発揮して被取付体1に押付けられて緩みを生ぜず、確実に固定される。
【0023】
また複数個のスタッド材3を一括して被取付体1に着脱可能に取付けるための好適な方法として被取付体1としての基板2に取付孔1aを前述のように所望複数個、所望配列に設ければ組立ラインでの自動組立により容易にスタッド材3を取付けることができる。この方法を述べると、取付けに際しては先ず図9に示すように所望本数のスタッド材3を略水平面I上の所定位置に同方向に倒立して配置する。
【0024】
次いで図10に示すようにスタッド材3に対して被取付体1を上方から載置することによりスタッド材3の基端部側に設けた取付部3bを被取付体1に設けた取付孔1aに合致して挿入する。
【0025】
この際、被取付体1の基板2に設けた取付孔1aは、図8に示すように幅方向としての短軸方向Yの左右の側面には直線状の内側面1a1 ,1a1 を有する小判形や楕円形のような平面長円形もしくは図には示さないが平面長多角形に形成されているので、この取付孔1a内に取付部3bが挿入されるスタッド材3は取付部3bの左右の係合壁面3b1 ,3b1 が取付孔1aの直線状の左右の内側面1a1 ,1a1 に係合することにより取付位置が位置決めされる。
【0026】
その後、図11に示すようにスタッド材3の取付部3bに設けた雌ねじ孔3d内に取付ねじ5を螺入することにより被取付体1にスタッド材3を取付ける。
【0027】
この際、被取付体1に設けた取付孔1aの直線状の内側面1a1 ,1a1 にスタッド材3の取付部3bに設けた左右の係合壁面3b1 ,3b1 が係合するので、スタッド材3は不用意に回動するのが規制され、後述するように取付部3b内に取付ねじ5をドライバーDにより螺入する時に容易かつ確実に螺入操作が行え、しかも取付後においてはスタッド材3のがたつきや緩みを防止することができる。
また複数個の取付ねじ5を雌ねじ孔3d内に螺入したり、螺退するには、多軸の自動ドライバーDを同時に上昇したり、同時に降下して取付ねじ5を回動操作することにより自動的に迅速かつ確実に行うことができる。
【0028】
このような取付方法によれば被取付体1の基板2に所望複数個のスタッド材3は、外径φが同一径であったり、または長さlが同一長さのスタッド材3に限って一括して着脱可能に取付けるのに限ることなく、スタッド材3の外径φが大小異なったり、長さlが長短異なる等の種類が異なるスタッド材3でも所望本数、所望配列にて着脱可能に一括して迅速かつ確実に基板2に取付けることができる。
【0029】
そして、経時の使用によりスタッド材3が磨耗したり、破損する等して交換を必要とする場合には、スタッド材3の雌ねじ孔3dから取付ねじ5をドライバーを用いて螺退すれば基板2の取付孔1aから所望配列、所望個数のスタッド材3を取外すことができる。
そして前述のようにして新しいスタッド材3を基板2に取付けることにより交換が行える。そして、基板2およびこの基板2に当初から取付けられているスタッド材3は新たに交換されたスタッド材3と一緒に廃棄することなくそのまま再使用でき、リサイクルが行える。
【0030】
【発明の効果】
本発明の請求項1は以上のようにスタッド材の一側の基端に形成される取付部の係合壁面部を被取付体に設けた平面略長円形もしくは平面略多角形をなす取付孔の短軸方向に位置する直線状の内側面に係合させてスタッド材の回動を規制し、取付ねじをスタッド材の取付部に設けた雌ねじ孔内に螺入してスタッド材に設けた拡大鍔部と前記取付ねじの周縁に、ばね性を発揮させるように逆皿状に形成された鍔部とにより被取付体をばね性にて挟持、固定してスタッド材を被取付体に取付けることを特徴とするので、基板にスタッド材を高い精度にて位置決めして不用意な回動が規制されて迅速かつ確実に取付け、またスタッド材に磨耗や破損を生じて交換を必要とする場合に所望個所、所望本数のスタッド材のみの取付けが行え、しかも部品の再使用につながり、またスタッド材が経時の使用により緩みやがたつきを生ずることがなく構造的に堅牢に取付けが行え、スタッド材の耐命性が向上する。
【0031】
また本発明の請求項3は、請求項2において、被取付体に設けられる取付孔を所望複数個所望配列にて設け、該取付孔内に複数個のスタッド材の取付部を挿入することにより一括して着脱可能に取付けることができる。
【0032】
また本発明の請求項4によると、請求項2または3において、所望本数のスタッド材を略水平面上の所定位置に同方向に倒立して配置し、スタッド材に対して被取付体を上方から載置することによりスタッド材の基端部を被取付体に設けた取付孔に合致して挿入し、スタッド材の取付部に設けた雌ねじ孔内に取付ねじを螺入することにより被取付体に複数個のスタッド材を精度良く迅速かつ確実に取付けるのに便利である。
