【発明が属する技術分野】
本発明は、ノート型パソコン・携帯電話等のハンディ式の電気機器において、機器の本体に対し開閉回動自在に組み付ける開閉蓋を、開放状態位置と閉鎖状態位置との二つの状態位置に切り換えて保持せしめるように、その開閉蓋の軸支部に装備するヒンジ装置についての改良に関する。
【０００２】
【従来の技術】
上述のハンディ式の電気機器におけるヒンジ装置の従前のものは、最も典型的な手段である携帯電話器に装備されるフリップを開閉自在に組み付ける軸支部に組み込むヒンジ部材について具体的にいえば、図１にあるように携帯電話器Ａのボディａに並列させた多数の押釦式のスイッチＳＷ…を組み付けることで装設する操作部ｂは、その携帯電話器Ａを、例えば、衣服のポケットに入れて収納しておいたときに、外部からの接触圧でスイッチＳＷが操作されるようになることを避けるため、フリップと呼ばれる開閉蓋ｃを、ヒンジ部材ｄによりボディａに開閉自在に軸支しておいて、通話の使用がないときには、この開閉蓋ｃにより操作部ｂを覆い込んでスイッチＳＷ…の操作が行われることのないようにしている。
【０００３】
そして、この開閉蓋ｃを軸支するヒンジ部材ｄは、図２にあるように、金属板で四角な角筒状に成形したケース１と、樹脂材により円盤状のフランジ２０の前後の両面に四角な角柱状の軸部２１・２２がそれぞれ突出する形状に成形されて、それの前面側に突出する角柱状の軸部２１が前記ケース１の前壁１ａに開設した透孔１０から突出する状態においてケース１内で回転するアクチュエータ（作動軸）２と、合成樹脂材によりキューブ状に成形されて、それの前端面に、前記作動軸２の後面側の軸部２２の軸芯部位に開設される中心穴に嵌合してその作動軸２を回転自在に支承する支軸３０が突出し、上下の両面にはバネ板４の組付部３１が形成されるバネ保持部材３と、バネ性を具備する金属板を側面視において先細りのコの字型に成形して前述のバネ保持部材３の外周面に組み付け保持させるバネ板４と、これら作動軸２とバネ保持部材３とバネ板４とを図３にあるように組み合わせて角筒状に形成してあるケース１内に挿入し、そのケース１の後端側に形設してあるラグ片１ｂ・１ｂの折曲げによるかしめ付けで図４にあるようにケース１内に組み込んだときに、作動軸２の前面側の軸部２１がケース１の透孔１０から突出するように押し出すテーパ状のコイルバネ５とで構成し、これらにより図５にあるようにヒンジ部材ｄに組み立て、このヒンジ部材ｄを、携帯電話器Ａのボディａに設けておく角穴ｅ内に挿入し、そこから突出してくる前述の作動軸２の前面側の角柱状の軸部２１を、開閉蓋ｃの基端側に形設しておく角穴（図示省略）に嵌合させることで、その開閉蓋ｃを開閉回動自在に軸支するようにしてある。
【０００４】
そして、このヒンジ部材ｄは、開閉蓋ｃを開放回動させると、その開閉蓋ｃに設けた角穴に、ケース１から突出している作動軸２の前端側の角柱状の軸部２１が嵌合していることで、この作動軸２がアクチュエータとして開閉蓋ｃと一体に回動するようになり、これにより、作動軸２の後端側の角柱状の軸部２２が、バネ保持部材３に組み付けてある側面視で先細りのコの字型をなすバネ板４の、一対に対向する作動片４ａと作動片４ａとの間において、それら作動片４ａ・４ａのバネ圧を受けながら回転するようになる。
【０００５】
これにより、開閉蓋ｃが閉鎖位置にあるときに、作動軸２の内端側の角柱状の軸部２２の四つの周面のうちの対向する二つの面に対して、一対の作動片４ａ・４ａが圧接してその作動片４ａ・４ａのバネ圧により軸部２２をその状態位置に保持しているとすると、開閉蓋ｃを開放させる回動の初期においては、角柱状の軸部２２が、それの距離の長い対角線上において対向する稜と稜とで作動片４ａ・４ａの間隔を拡げながらその作動片４ａ・４ａに圧接するようになっていくことによりバネ圧に抗して回動するようになって、その開放回動の進行で、軸部２２の周面と作動片４ａ・４ａとの接触点となる軸部２２の対向する稜と稜とが死点越えしたところで、作動片４ａ・４ａのバネ圧が開閉蓋ｃを開放側に付勢するように働いて、開閉蓋ｃを開放させるようになり、その作動片４ａ・４ａが、作動軸２の内端側の軸部２２の対向する二つの面に圧接した状態において開放回動を停止させ、その状態位置に保持するようになる。
【０００６】
そして、開放した開閉蓋ｃをさらに開放側に強く回動させると、作動軸２の内端側の軸部２２が対向する作動片４ａ・４ａの間隔を拡げるようになってバネ圧が働き、そのさらなる開放側への負荷を解放することで、バネ圧により開放位置に復元していくようになる。
【０００７】
また、開放状態位置にある開閉蓋ｃを閉鎖側に回動させると、その初期においては、作動軸２の内端側の軸部２２が一対の作動片４ａ・４ａの間を押し拡いていくことでバネ圧の抵抗を受けるが、その内端側の軸部２２の対向する稜が作動片４ａ・４ａに対し死点越えしたところで、バネ圧により閉鎖側に回動するようになって、そのバネ圧で閉鎖されるようになる。
【０００８】
ケース１から突出する作動軸２の前面側（外端側）の軸部２１は、それを押し込むと、バネ板４およびそれを組み付けたバネ保持部材３と一緒に、ケース１内に向けテーパー状のコイルバネ５を押し縮めながらケース１内に没入していくようになるが、この押し込み作動は開閉蓋ｃを携帯電話器Ａのボディａに組み付けるときに行うもので、開閉蓋ｃを組み付け後においては、突出した状態位置に保持されるものである。
【０００９】
【発明が解決しようとする課題】
上述のヒンジ部材ｄは、作動軸２により開閉回動するよう軸支した開閉蓋ｃを、作動軸２に作用させるバネ板４により閉鎖側に回動させる状態と開放側に回動させる状態とに切り換えて付勢するのに、作動軸２の内端側の軸部２２を、四角な角柱状に形成しておいて、それの四つの周面のうちの一対に対向する周面に、側面視において先細りのコの字型に成形したバネ板４の一対に対向する作動片４ａ・４ａの各遊端側を、圧接させておいて、その作動片４ａ・４ａの遊端側が軸部２２の周面を押圧するバネ圧によって、作動軸２を、それの軸芯線中心に回転させるようにすることから、このバネ板４のバネ圧が、主として、コの字型に折曲げ成形してあるバネ板４の主体部の上下の端部から、上下に一対の各作動片４ａ・４ａに向けて屈曲する屈曲部における曲げのバネ性によって生成されることになり、耐久性が低く、また、作動片４ａ・４ａ自体のバネ性は殆ど利用できないものとなっていることで、バネ圧が弱い問題がある。
【００１０】
このため、バネ圧を強くして、開閉蓋ｃの開放回動がスナップアクション式にシャープに行われるようにするためには、バネ板４を何層にも重ねるようにしなければならず、製作が面倒な問題がある。
【００１１】
また、作動軸２とバネ板４とを組み合わせて組み立てるときに、作動軸２の内端側の軸部２２の周面が、一対の作動片４ａ・４ａの対向する間隔内において、それら作動片４ａ・４ａにより強く挟持された状態となるように、その内端側の軸部２２を一対の作動片４ａ・４ａの間隔内に嵌装させるようにするが、このとき、狭い間隔で対向している作動片４ａ・４ａの遊端側の間隔内に対して、その間隔よりも当然に太い寸法に形成してある作動軸２の内端側の軸部２２を嵌め込むのがむづかしいことで、組み立て作業が厄介な問題がある。
【００１２】
また、ヒンジ部材ｄを組み立てるのに、角筒状のケース１と、作動軸２と、バネ保持部材３と、コの字型に屈曲成型したバネ板４と、テーパー状のコイルバネ５との少なくとも５つの部品を要することで、部品点数が多く製作・組み立てを面倒にしている問題がある。
【００１３】
本発明は、従前手段に生じているこれらの問題を解決するためになされたものであって、作動軸の軸部の周面に圧接して、回転方向に付勢するバネ板のバネ性が、対向して作動軸の軸部に圧接する作動片自体のバネ性から得られるようにして、側面視においてコの字型に屈曲成型するバネ板の屈曲部の耐久性を向上させ、かつ、このコの字型に成形するバネ板に対する作動軸の組み付けが簡単に行えるようにし、しかも、部品を少なくする新たな手段を提供することを目的とする。
【００１４】
【課題を解決するための手段】
この目的を達成するために、本発明においては、まず、バネ性を具備する金属板の屈曲成型により側面視においてコの字型に成形するバネ板の、一対に対向する作動片のバネ性を、強くしながら耐久性のあるものとし、かつ、作動軸の内端側の軸部との嵌合組み付けを容易にするための手段として、このバネ性を具備する金属板から屈曲成型して形成するコの字型のバネ板は、それの一対に対向する作動片を、それの長手方向の中間部位が対向側に弧状に張り出すようアーチ状に彎曲した形状に形成して、そのアーチ状の作動片の長手方向の中間の張出部を作動軸の内端側の角柱状の軸部の周面に圧接させるようにし、このバネ板を、組み付け保持せしめるバネ保持部材には、組み付けたバネ板の一対の作動片の外周側に、その作動片の遊端側をスライド自在に支承する支承面を設けておいて、弧状の作動片が、それのバネ板の主体部に連続する基端側の屈曲部と支承面に圧接する遊端側との２点により支承されて、作動軸の内端側の角柱状の軸部により弧状の作動片の中間の張出部が押圧されたときに、この弧状の作動片が平板状に潰されるよう変形しながら伸び出すようになって、弧状の作動片自体のバネ性を発揮するようになり、また、このバネ板を、それの一対に対向する作動片の対向間隔内に、作動軸の内端側の角柱状の軸部が位置しているようにその作動軸と組み合わせるときの組み付け作業が、作動軸の内端側の軸部を、アーチ状の作動片の対向間隔内に、間隔が拡いている遊端側から差し込んでいくだけで簡単に行えるようになる手段を提起するものである。
【００１５】
また、コの字型のバネ板と角柱状の作動軸の軸部とを組み合わせて組み立てるヒンジ部材の部品点数を少なくするため、コの字型に屈曲成型したバネ板を組み付け保持せしめるバネ保持部材を、合成樹脂材により角柱状の立方体に成形して、これにコの字型に成形したバネ板を組み付け保持せしめるようにし、かつ、組み付けるコの字型のバネ板は、それの一対に対向する作動片が、このバネ保持部材の内部に形設しておく空室内において対向して、その空室内に収蔵される作動軸の内端側の軸部の周面に圧接していくようにすることで、このバネ保持部材が、角筒状のケースを兼ねたものとして、角筒状のケースを省略して部品点数を少なくする手段を提起するものである。
【００１６】
さらに、角柱状に形成して、コの字型に成形したバネ板の一対の作動片の対向間隔内に配位する作動軸の内端側の角柱状の軸部を、それの周囲のそれぞれの周面が、それぞれ突出端に向け次第に巾を縮小させるよう先細りのテーパー状に成形して、この先細りの角柱状の軸部の周面に、コの字型のバネ板の一対の作動片が、それの具備するバネ圧で、圧接してきたときに、その軸部の周面に対し圧接する作動片の接触部位に加えられるバネ圧により、テーパー状をなす作動軸の内端側の軸部を絞り出すように軸方向に動かすようにし、これにより、作動片の接触部位が先細りの軸部の小径側に位置してくることで、作動軸の外端側の軸部が、バネ保持部材から作動軸が外端側に向けて押し出されて、その作動軸の外端側の軸部がバネ保持部材の外端側から突出する状態となり、この突出してきた作動軸の外端側の軸部を、作動片による押出方向のバネ圧に抗して押し返すことで、その作動軸の内端側の軸部の周面に対する作動片の接触部位が、テーパー状の軸部の拡径側に動いて、作動軸を押し込まれた状態となるようにして、作動軸をそれの外端側の軸部が突出する状態位置に押し出すために作用させていたテーパー状のコイルバネを省略し得るようにする手段を提起するものである。
【００１７】
【発明の実施の形態】
次に本発明の実施の態様を説明する。
本発明手段によるハンディ式の電気機器における開閉蓋の軸支部に装備せしめるヒンジ部材ｄは、基本的には、図６に示しているように、バネ性を具備する金属板を折曲げ成形して側面視においてコの字型をなす形状に形成するバネ板４と、このバネ板４を組み付け保持せしめるように合成樹脂材で成形するバネ保持部材３と、外端側には開閉蓋の回動軸部に対して嵌合して連結する軸部２１を具備し内端側には角柱状の軸部２２を具備する形状に形成する作動軸２と、を用い、これらを、バネ保持部材３にバネ板４を組み付け保持せしめ、そのバネ板４の一対の作動片４ａ・４ａの対向間隔内に作動軸２の内端側の軸部２２が位置して作動片４ａ・４ａのバネ圧を受けるように組み合わせ、作動軸２がそれの外端側の軸部２１と嵌合連結する開閉蓋ｃの回動によりその開閉蓋ｃと一緒に回動したときに、作動片４ａ・４ａに対し接触する内端側の角柱状の軸部２２の稜と周面との角度が変動することで、作動片４ａ・４ａからのバネ圧により作動軸２が受ける回転方向の付勢の方向が正逆に変わって、開閉蓋ｃを開放回動の方向と閉鎖回動の方向に切り換わるようにすることについては、従来手段のヒンジ部材ｄと同様に構成する。
【００１８】
しかし、バネ性を具備する金属板からそれを所定形状に打ち抜いて屈曲成形することで側面視においてコの字型をなす形状に形成するバネ板４は、それの座板状に形成する主体部４ｂの対向する辺縁部から屈曲させて一対に対向するように形成する作動片４ａ・４ａを、図６の右端側に示しているように、それの突出方向となる長手方向の中間部位が、対向側に弧状に張り出すようアーチ状に彎曲させた形状に成形する。
【００１９】
この作動片４ａ・４ａの彎曲成形は、作動片４ａ・４ａの長手方向の全域がアーチ状になるようにする場合に限らず長手方向の中間部位がアーチ状になるようにしてよい。
【００２０】
また、図７乃至図１０に示している実施例にあるように、座板状に形成した主体部４ｂの上下の辺縁から、それぞれループ状の屈曲部４ｃを経て、ゆるく主体部４ｂの内側（図８において右側）に向け屈曲させ、その屈曲部４ｃから突出端となる遊端に至る間を、対向側に弧状に張り出すアーチ状に彎曲する形状に成形することが望ましい。
【００２１】
このとき、作動片４ａ・４ａの遊端となる突出側の端部は、ほぼ屈曲部４ｃに対応する高さ位置を占め、この状態において長手方向の中間部が、それぞれ弧状に対向側に張り出して、その弧状の張出部が、前述の作動軸２の内端側の軸部２２の径よりも狭くした間隔で一対に対向するように成形することが有効である。
【００２２】
そして、この弧状に彎曲するよう成形する作動片４ａ・４ａの遊端側には、水平な方向に突出する支え部４０を装設するようにする。この支え部４０は、バネ板４を図２９〜図３１にあるようにバネ保持部材３に組み付け保持せしめたときに、この支え部４０が、作動片４ａ・４ａの外周側に位置させてバネ保持部材３に形設しておく支承面３ａにスライド自在に当接して、アーチ状の作動片４ａを屈曲部４ｃとこの遊端側の支え部４０との二点で支えるようになって、弧状の張出部に負荷がかかり、作動片４ａの弧状の張出部の全体が潰されるように変形したときに、この支え部４０が支承面３ａ上をスライドして作動片４ａを突出方向に伸び出させ、これにより、作動片４ａ自体のバネ性を効果的に発揮させるようにする。
【００２３】
このバネ板４を組み付け保持せしめるバネ保持部材３は、合成樹脂材により、図６の左端側に示しているように、前面側が開放する中空の筒状に成形して、これに組み付け保持せしめるバネ板４の一対の作動片４ａ・４ａがこのバネ保持部材３の内部に形成して空室内に収蔵されるようにする。
【００２４】
このバネ保持部材３に対するバネ板４の組み付けは、従前手段のものと同様に、コの字型に形成したバネ板４を、それの屈曲部４ｃのバネ性を利用してかしめ付けるなどの適宜の手段で行ってよい。図１１乃至図３２に示している実施例のバネ保持部材３においては、それの前面側（図１２において左面側）の開放口の口縁部位に、バネ板４の座板状に形成した主体部４ｂが嵌合する凹部３ｂを、図１１にあるようその主体部４ｂの輪郭形状に対応する形状に形成しておいて、バネ板４を、それの一対の作動片４ａ・４ａが先になる姿勢として、その作動片４ａ・４ａをバネ保持部材３の前面側の開放口から挿し込んでいき、それにより、バネ保持部材３の前端面に衝合するバネ板４の座板状の主体部４ｂをこの凹部３ｂに嵌合させることで、組み付け保持が行われるようにしている。
【００２５】
そして、この例においては、作動片４ａ・４ａの遊端側で、作動片４ａ・４ａの巾方向の中間部位に外周側に突出するランス４１が、作動片４ａを形成する金属板から切り起こすように形設してあって、作動片４ａ・４ａが、図１１乃至図１４にある形状に成形してあるバネ保持部材３の内腔に差し込まれて、それの遊端部のランス４１がバネ保持部材３の内腔の天井部と底板部とに、作動片４ａ・４ａの外周側に対向するよう形設してある支承面３ａ・３ａに圧接してそこを摺動しながらバネ保持部材３の内腔の後部側に向け挿し込まれていくとき、支承面３ａの後端側に形設してあるランス４１に対応する巾の切欠部３ｃ・３ｃに達したところで、この遊端部のランス４１が切欠部３ｃ内に落ち込み、弧状の作動片４ａ・４ａがそれに付与してあるバネ性により遊端部に形設してある支え部４０が支承面３ａに衝合するまで外周側に拡くことにより、この遊端部に形設してある前述のランス４１が、図１５にあるように、支承面３ａに形設した切欠部３ｃの前縁に係止することで脱出が阻止されて、バネ板４のバネ保持部材３に対する組み付け保持が完了するようにしてある。
【００２６】
これによるバネ板４のバネ保持部材３に対する組み付けは、さらに、作動軸２を組み付けて、ヒンジ部材ｄに組み立て、作動軸２を回転させて内端側の軸部２２の回動により、それの周面に圧接する弧状の作動片４ａ・４ａの張出部が押し込まれたとき、図２１・図２５・図２９にあるように、作動片４ａが平に押し潰されていくことで長手方向に伸び出すことによりランス４１が支承面３ａの後端側に設けた窓穴状の切欠部３ｃの前縁から離れるようになることから、ヒンジ部材ｄに組み立てた状態においては仮とじの状態ではあるが、この実施例においては、バネ保持部材３がケース１を兼ねた形態としてヒンジ部材ｄを組み立て、ケース１を省略した構成として、バネ保持部材３に組み付けたバネ板４の座板状の主体部４ｂがヒンジ部材ｄの前端面（外端面）に位置し、この主体部４ｂに設けた透孔４２から作動軸２の外端側の軸部２１が突出するようにしてあることから、組み立てたヒンジ部材ｄを、電気機器である携帯電話器Ａのボディａに設けてある角穴内に挿入して、そのヒンジ部材ｄの外端側に突出する作動軸２の外端側の軸部２２を、ボディａにする開閉蓋ｃの回動軸部に設ける角穴に嵌合して連結したとき、ヒンジ部材ｄの外端面に位置するバネ板４の座板状の主体部４ｂが、開閉蓋ｃの回動軸部の端面に当接して、軸方向に動かないよう押さえられるようになるので、弧状の作動片４ａ・４ａが作動軸２の内端側の軸部２２の回動により押し潰される方向の荷重を受けても、それにより脱出方向に動くことはなく、組み付けた状態に保持され、従って、前述の仮とじの状態が、ヒンジ部材ｄの組み付けにより本とじの状態となる。
【００２７】
バネ保持部材３は、前述した如く、前面側（外端側）に開放口を具備する中空の筒状に成形し、それの内部に形成される空室の天井部および底壁部に、該バネ保持部材３に組み付け保持せしめるバネ板４の主体部４１から、一対に対向するよう屈曲して弧状に彎曲成形した作動片４ａ・４ａの遊端側の端部に衝合して支承する支承面３ａ・３ａを、それぞれ形設するが、図１１乃至図１５に示している実施例においては、中空の筒状に成形したこのバネ保持部材３の後面側（内端側）の端部に、そこを塞ぐ蓋板３３を設けて、その前面側の中心部位に、バネ保持部材３の前面側の開放口に向けて突出する支軸３４を設けて、これに、作動軸２を軸方向の摺動と回転方向の回動とが自在に行われるように軸支するようにしている。
【００２８】
作動軸２は、金属材または合成樹脂材により図１６乃至図１９にあるように、円盤状のフランジ２０の前面となる前端側（外端側）に開閉蓋ｃの回動軸部に対し嵌合して連結する角柱状の軸部２１を設け、フランジ２０の後面となる後端側（内端側）にバネ板４の一対の作動片４ａ・４ａの対向間隔内に位置さす角柱状の軸部２２を具備する形状に成形するが、それの内端側の軸部２２軸心部位には、図１９にあるよう前述のバネ保持部材３に設ける支軸３４に対し嵌合する軸穴２３が形設してあって、この軸穴２３を前述の支軸３４に嵌挿することで、図２１・図２５・図２９にあるように、支軸３４上を前後に摺動し、また、図２９乃至図３２にあるように、支軸３４中心に回動することで、弧状の作動片４ａ・４ａの対向間隔を拡縮するようにしている。
【００２９】
そしてまた、この作動軸２は、それの後端側（内端側）の軸部２２が、図６および図１６乃至図１９の各図にあるように、四つの周面のそれぞれが、後方に向かい次第に巾を縮小させるよう先細りのテーパー状に成形してあって、そのテーパー状の周面に、弧状に彎曲成形してある作動片４ａ・４ａの張出部が圧接してくることで、それの接触部位がテーパー面を先細りの側に動くようになって作動軸２を前端側（外端側）に押し出していくようにしてある。
【００３０】
このことから、この作動軸２の内端側の軸部２２を先細りのテーパー状とした実施例においては、バネ板４の一対の作動片４ａ・４ａが作動軸２を外端側に押し出すバネを兼ねたものとなって、従前手段のテーパー状のコイルバネ５を省略でき、部品点数を少なくするとともにヒンジ部材ｄの容積を小さくできるようになる。
【００３１】
また、この実施例においては、作動軸２を組み込むときに、バネ保持部材３に組み付ける前のバネ板４に対し、それの一対の作動片４ａ・４ａの拡径するよう拡いている遊端側に、作動軸２を、それの外端側の軸部２１が先になる姿勢として、図３３にあるように臨ませ、その状態から作動軸２を作動片４ａ・４ａの間隔内に差し込み、円盤状のフランジ２０が作動片４ａ・４ａに圧接したところで強く押し込めば、そのフランジ２０の後面側に続く作動軸２のテーパー状とした内端側の軸部２２の周面が弧状の作動片４ａ・４ａの張出部に圧接してくることにより、このテーパー状の軸部２２の周面によって作動軸２が前面側（外端側）に押し出され、作動軸２の外端側の軸部２１がバネ板４の主体部４ｂに開設してある透孔４２内に突入し、フランジ２０の周縁部が透孔４２の口縁に衝合して、図３４にある状態となってくるから、このバネ板４と作動軸２との組み合わせが簡単に行えるようになる。
【００３２】
そして、このように作動軸２を組み付け保持せしめた状態のバネ板４を、それの作動片４ａ・４ａが先になる姿勢として、その作動片４ａ・４ａをバネ保持部材３の前面側の開放口から挿し込んでいけば、作動軸２の内端側の軸部２２が支軸３４に嵌合し、バネ板４の作動片４ａ・４ａの遊端側のランス４１がバネ保持部材３の支承面３ａの後端側に窓穴状に形設した切欠部３ｃに係止することで、ヒンジ部材ｄに組み立てられるようになるから、組み立ても簡単な作業で行えるようになる。
【００３３】
また、この例のバネ保持部材３は、それの外周の形状を四つの周面を具備する角柱状に形成して、従前手段におけるケース１の役割を果たすようにあって、これにより、バネ保持部材３に、作動軸２をバネ板４に組み合わせた状態として、そのバネ板４を組み付けることで、ヒンジ部材ｄに組み立て、そのヒンジ部材ｄを携帯電話器Ａのボディａに設けた角穴ｅに嵌挿することによって、ケース１を省略した形態で開閉蓋ｃの軸着・連結が行えるようになる。
【００３４】
次に、図３６乃至図３９は、バネ板４の一対の作動片４ａ・４ａのバネ圧を増強させるための補助バネ板４’を示している。
【００３５】
この補助バネ板４’は、前述のバネ板４を成形するバネ性を具備する金属板を用いて、そのバネ板４と略同形に成形してあって、そのバネ板４の内面側に重合させることで、バネ板４を２層に積層して一体的に組み合わされた状態となってバネ板４の板厚を増大させ、これによりバネ性を補強したものとして用いるようにする。そして、この補助バネ板４’はランス４１を形設しない形態のものとしてある。
【００３６】
なお、前述の図２０乃至図３５に示している実施例におけるバネ板４は、この補助バネ板４’を内側に積層して２枚重ねとしたものとして用いている。
【００３７】
次に、図４０乃至図４４はバネ板４をバネ保持部材３に組み付け保持せしめる手段の別の例を示している。
【００３８】

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a hand-held electric device such as a notebook personal computer or a mobile phone, in which an opening / closing lid that is assembled to the main body of the device so as to be openable and closable is switched between an open state position and a closed state position. The present invention relates to an improvement in a hinge device provided on a pivot portion of an opening / closing lid so as to be held.
[0002]
[Prior art]
The conventional hinge device in the above-mentioned hand-held electric device is a hinge device which is the most typical means and which is incorporated in a pivot supporting portion for assembling a flip which can be opened and closed, which is mounted on a portable telephone, specifically, FIG. As shown in FIG. 1, an operating unit b provided by assembling a large number of push-button switches SW arranged in parallel with the body a of the mobile phone A puts the mobile phone A in, for example, a pocket of clothes. In order to prevent the switch SW from being operated by an external contact pressure when the switch SW is stored, an opening / closing lid c called a flip is pivotally supported on the body a by a hinge member d so as to be openable and closable. When the telephone is not used, the operation unit b is covered with the opening / closing lid c so that the switches SW are not operated.
[0003]
As shown in FIG. 2, a hinge member d for pivotally supporting the opening / closing lid c is provided on the front and rear surfaces of a case 1 formed of a metal plate into a square tube shape and a disk-shaped flange 20 made of a resin material. The square pillar-shaped shaft portions 21 and 22 are formed into shapes that project from each other, and the prism-shaped shaft portion 21 that projects toward the front side thereof projects from the through hole 10 formed in the front wall 1 a of the case 1. An actuator (operating shaft) 2 rotating in the case 1 in a state and a cube made of a synthetic resin material are formed in a front end face thereof at a shaft center portion of a shaft portion 22 on a rear surface side of the operating shaft 2. A support shaft 30 that fits into a center hole to be supported and rotatably supports the operating shaft 2 protrudes, and a spring holding member 3 in which an assembly portion 31 of a spring plate 4 is formed on both upper and lower surfaces; Formed into a tapered U-shape in side view Then, the spring plate 4 to be assembled and held on the outer peripheral surface of the spring holding member 3 and the operating shaft 2, the spring holding member 3 and the spring plate 4 are combined as shown in FIG. When the lug pieces 1b and 1b formed on the rear end side of the case 1 are inserted into the case 1 by bending and crimping the lug pieces 1b and 1b as shown in FIG. 2 is composed of a tapered coil spring 5 which is pushed out so that a shaft portion 21 on the front side protrudes from the through hole 10 of the case 1, thereby assembling a hinge member d as shown in FIG. Is inserted into a square hole e provided in the body a of the mobile phone A, and the above-mentioned prism-shaped shaft portion 21 on the front side of the operating shaft 2 protruding therefrom is placed on the base end side of the opening / closing lid c. By fitting it into a square hole (not shown) It is so as to rotatably supporting the lid c openably pivoted.
[0004]
When the opening and closing cover c is opened and rotated, the hinge member d is fitted in a square hole provided in the opening and closing cover c with a prismatic shaft portion 21 on the front end side of the operating shaft 2 protruding from the case 1. As a result, the operating shaft 2 rotates integrally with the opening / closing lid c as an actuator, whereby the prismatic shaft portion 22 on the rear end side of the operating shaft 2 is The spring plate 4, which is formed into a tapered U-shape in a side view, rotates between the pair of opposing operating pieces 4a and 4a while receiving the spring pressure of the operating pieces 4a. Become like
[0005]
Accordingly, when the opening / closing lid c is in the closed position, a pair of the operating pieces 4a is opposed to two opposing surfaces of the four peripheral surfaces of the prismatic shaft portion 22 on the inner end side of the operating shaft 2. Assuming that the shaft portion 22 is held in that state by the spring pressure of the operating pieces 4a, 4a, the shaft portion 22 is in the initial stage of the rotation for opening the opening / closing lid c. However, the ridges opposing each other on the diagonal line having a long distance between the ridges and the ridges are pressed against the operating pieces 4a while expanding the interval between the operative pieces 4a. When the opening of the shaft 22 is advanced, the opposing ridges of the shaft 22 which are the contact points between the peripheral surface of the shaft 22 and the operating pieces 4a and 4a, and the ridges exceed the dead center, The spring pressure of the operating pieces 4a, 4a acts to urge the open / close lid c to the open side, and the open / close lid When the operating pieces 4a and 4a are pressed against two opposing surfaces of the shaft portion 22 on the inner end side of the operating shaft 2, the opening rotation is stopped and the operating piece 4a is held at that state. Become like
[0006]
Then, when the opened cover c is further strongly rotated to the open side, the shaft portion 22 on the inner end side of the operation shaft 2 increases the interval between the opposing operation pieces 4a, 4a, and a spring pressure acts. By releasing the load on the further open side, the open position is restored by the spring pressure.
[0007]
Further, when the opening / closing lid c in the open position is rotated to the closing side, the shaft portion 22 on the inner end side of the operating shaft 2 pushes and expands between the pair of operating pieces 4a at the initial stage. Therefore, when the opposing ridge of the shaft portion 22 on the inner end side exceeds the dead center with respect to the operating pieces 4a and 4a, the shaft portion 22 turns to the closing side by the spring pressure, It will be closed by the spring pressure.
[0008]
When the shaft portion 21 protruding from the case 1 on the front side (outer end side) of the operating shaft 2 is pushed, the shaft portion 21 is tapered into the case 1 together with the spring plate 4 and the spring holding member 3 to which the spring plate 4 is attached. The coil spring 5 is immersed in the case 1 while being compressed, but this pushing operation is performed when the opening / closing lid c is attached to the body a of the mobile phone A, and after the opening / closing lid c is attached. Are held in a protruding state position.
[0009]
[Problems to be solved by the invention]
The above-described hinge member d has a state in which an opening / closing lid c pivotally supported so as to open and close by the operating shaft 2 is rotated to a closed side and a state to be opened to the open side by a spring plate 4 acting on the operating shaft 2. In order to switch and energize, the shaft portion 22 on the inner end side of the operating shaft 2 is formed in a square prism shape, and on a peripheral surface facing a pair of the four peripheral surfaces thereof, The free ends of the operating pieces 4a, 4a opposed to a pair of spring plates 4 formed in a tapered U-shape in side view are pressed against each other, and the free ends of the operating pieces 4a, 4a are shaft portions. Since the operating shaft 2 is rotated about the axis of the operating shaft 2 by a spring pressure that presses the peripheral surface of the spring 22, the spring pressure of the spring plate 4 is mainly bent into a U-shape. Bent from the upper and lower ends of the main body of the spring plate 4 to the pair of operating pieces 4a. Is generated due to the spring property of the bending at the bent portion, and the durability is low, and the spring property of the working pieces 4a itself is hardly available. is there.
[0010]
Therefore, in order to increase the spring pressure so that the opening and closing of the opening / closing lid c is sharply performed in a snap-action manner, the spring plates 4 must be stacked in multiple layers. There is a troublesome problem.
[0011]
When assembling the operating shaft 2 and the spring plate 4 in combination, the peripheral surface of the shaft portion 22 on the inner end side of the operating shaft 2 is set so that the operating members 4a The inner end side shaft portion 22 is fitted in the space between the pair of operating pieces 4a and 4a so that the shaft portion 22 is strongly sandwiched by the 4a and 4a. It is difficult to fit the shaft portion 22 on the inner end side of the operating shaft 2 which is naturally formed to have a larger dimension than the gap on the free end side of the operating pieces 4a. There is a problem that the assembling work is troublesome.
[0012]
In order to assemble the hinge member d, at least the rectangular cylindrical case 1, the operating shaft 2, the spring holding member 3, the spring plate 4 bent and formed into a U-shape, and the tapered coil spring 5 are used. Since five parts are required, there is a problem that the number of parts is large and the production / assembly is troublesome.
[0013]
The present invention has been made to solve these problems occurring in the conventional means, and the spring property of a spring plate that presses against the peripheral surface of the shaft portion of the operating shaft and urges in the rotational direction is provided. As a result, the durability of the bent portion of the spring plate that is bent and formed into a U-shape in side view is improved, as obtained from the spring property of the operating piece itself pressed against the shaft portion of the operating shaft in opposition, and An object of the present invention is to provide a new means for easily assembling an operating shaft to a U-shaped spring plate and reducing the number of parts.
[0014]
[Means for Solving the Problems]
In order to achieve this object, in the present invention, first, the spring property of a pair of opposing operating pieces of a spring plate formed into a U-shape in side view by bending and molding a metal plate having spring property is set. As a means for making it strong and durable, and for facilitating fitting and assembling with the shaft portion on the inner end side of the operating shaft, it is formed by bending from a metal plate having this spring property. The U-shaped spring plate is formed in such a manner that an operating piece opposed to a pair of the U-shaped spring plates is formed into an arched shape such that an intermediate portion in a longitudinal direction thereof protrudes in an arc shape to the opposite side, and the arched shape is formed. An intermediate projecting portion in the longitudinal direction of the working piece was pressed against the peripheral surface of the prismatic shaft portion on the inner end side of the working shaft, and this spring plate was assembled to a spring holding member for assembling and holding. On the outer peripheral side of a pair of operating pieces of the spring plate, the free ends of the operating pieces Is provided with a bearing surface for slidably supporting the spring plate, and the arc-shaped operating piece has two points: a bent portion on the base end side continuous with the main portion of the spring plate and a free end side pressed against the bearing surface. When the intermediate projecting portion of the arc-shaped operating piece is pressed by the prism-shaped shaft portion on the inner end side of the operating shaft, the arc-shaped operating piece expands while being deformed to be crushed into a flat plate shape. As a result, the arc-shaped actuating piece itself exerts its spring property, and the spring plate is positioned at the inner end side of the actuating shaft within the opposing interval between the pair of opposing pieces. The assembling work when assembling with the operating shaft so that the pillar-shaped shaft portion is located is performed by moving the shaft portion on the inner end side of the operating shaft into a space in which the space between the arch-shaped working pieces is opposed to each other. It proposes a means that can be easily performed simply by inserting from the end side.
[0015]
Also, in order to reduce the number of parts of the hinge member assembled by combining the U-shaped spring plate and the shaft portion of the prismatic operating shaft, a spring holding member for assembling and holding a U-shaped bent spring plate. Is formed into a prismatic cube by a synthetic resin material, and a U-shaped spring plate is assembled and held on the cube, and the U-shaped spring plate to be assembled is opposed to a pair thereof. The working piece is opposed to the inside of the chamber to be formed inside the spring holding member, and is pressed against the peripheral surface of the shaft portion on the inner end side of the working shaft stored in the chamber. By doing so, the spring holding member also serves as a rectangular cylindrical case, and a means for reducing the number of parts by omitting the rectangular cylindrical case is proposed.
[0016]
Furthermore, the prismatic shaft portion on the inner end side of the operating shaft, which is formed in the shape of a prism and is arranged within the opposed interval of the pair of working pieces of the U-shaped spring plate, is formed around the periphery thereof. Are formed into a tapered shape so that the width gradually decreases toward the protruding end, and a pair of operating pieces of a U-shaped spring plate are formed on the circumferential surface of the tapered prismatic shaft. However, when it comes into pressure contact with the spring pressure of the shaft, the spring pressure applied to the contact portion of the working piece pressed against the peripheral surface of the shaft portion causes the shaft on the inner end side of the tapered working shaft to be pressed. The contact portion of the working piece is located on the small diameter side of the tapered shaft portion, so that the shaft portion on the outer end side of the working shaft is a spring holding member. The operating shaft is pushed out toward the outer end side, and the shaft portion on the outer end side of the operating shaft is a spring holding member. The operating shaft protrudes from the outer end, and the outer shaft of the operating shaft that has protruded is pushed back against the spring pressure in the pushing direction of the operating piece to thereby return the inner shaft of the operating shaft. The contact portion of the operating piece against the peripheral surface of the shaft moves to the diameter-expanding side of the tapered shaft so that the operating shaft is pushed in, and the shaft at the outer end of the operating shaft protrudes. The present invention provides a means for eliminating the need for the tapered coil spring that has been used to push the coil spring to the position where the coil spring is pushed.
[0017]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, embodiments of the present invention will be described.
As shown in FIG. 6, the hinge member d mounted on the pivot of the opening / closing lid in the hand-held electric device according to the present invention is basically formed by bending a metal plate having spring properties. A spring plate 4 formed in a U-shape in a side view, a spring holding member 3 formed of a synthetic resin material so as to assemble and hold the spring plate 4, and a rotation of an opening / closing lid on an outer end side. An operating shaft 2 having a shaft portion 21 fitted and connected to the shaft portion and having a prismatic shaft portion 22 on the inner end side is used. The spring plate 4 is assembled and held, and the shaft portion 22 on the inner end side of the operating shaft 2 is positioned within the space between the pair of operating pieces 4a, 4a of the spring plate 4 to reduce the spring pressure of the operating pieces 4a, 4a. The operating shaft 2 is fitted and connected to the shaft portion 21 on the outer end side thereof. When the opening / closing lid c is rotated together with the opening / closing lid c, the angle between the ridge of the inner end side prismatic shaft portion 22 that contacts the operating pieces 4a and 4a and the peripheral surface changes. As a result, the direction of the bias in the rotational direction applied to the operating shaft 2 by the spring pressure from the operating pieces 4a, 4a is changed in the forward and reverse directions, and the opening / closing lid c is switched between the opening rotation direction and the closing rotation direction. The configuration is the same as that of the hinge member d of the conventional means.
[0018]
However, the spring plate 4, which is formed into a U-shape in a side view by punching it out of a metal plate having spring properties into a predetermined shape and bending it, has a main part formed in a seat plate shape thereof. As shown on the right end side of FIG. 6, the operation pieces 4a, 4a formed to bend from the opposing edges of the 4b so as to be opposed to each other have an intermediate portion in the longitudinal direction that is the projecting direction thereof. Then, it is formed into a shape curved in an arch shape so as to protrude in an arc shape on the opposite side.
[0019]
The curved forming of the operating pieces 4a is not limited to the case where the entire area in the longitudinal direction of the operating pieces 4a is arched, and the intermediate portion in the longitudinal direction may be arched.
[0020]
As shown in the embodiment shown in FIGS. 7 to 10, the upper and lower edges of the main body portion 4b formed in the shape of a seat plate are loosely passed through the loop-shaped bent portions 4c and inside the main body portion 4b. It is desirable to bend toward (to the right in FIG. 8) and to form an arc-shaped curve extending from the bent portion 4c to the free end, which is a protruding end, to protrude in an arc shape on the opposite side.
[0021]
At this time, the protruding ends serving as the free ends of the operating pieces 4a occupy a height position substantially corresponding to the bent portion 4c, and in this state, the intermediate portions in the longitudinal direction project toward the opposite sides in an arc shape, respectively. Therefore, it is effective to form the arc-shaped overhanging portions so as to face each other at intervals smaller than the diameter of the shaft portion 22 on the inner end side of the operating shaft 2.
[0022]
A support portion 40 projecting in the horizontal direction is provided on the free end side of the operating piece 4a, which is formed to be curved in an arc shape. When the spring plate 4 is assembled and held on the spring holding member 3 as shown in FIGS. 29 to 31, the support portion 40 is positioned on the outer peripheral side of the operation pieces 4a. It comes into sliding contact with a bearing surface 3a formed on the holding member 3 to support the arch-shaped operating piece 4a at two points: a bent portion 4c and a support portion 40 on the free end side. When a load is applied to the arc-shaped overhang, and the entire arc-shaped overhang of the operation piece 4a is deformed so as to be crushed, the support portion 40 slides on the bearing surface 3a to move the operation piece 4a in the projecting direction. , Thereby effectively exerting the spring property of the operation piece 4a itself.
[0023]
The spring holding member 3 for assembling and holding the spring plate 4 is formed of a synthetic resin material into a hollow cylindrical shape whose front side is open as shown on the left end side in FIG. A pair of operating pieces 4a of the plate 4 are formed inside the spring holding member 3 so as to be stored in the empty room.
[0024]
The spring plate 4 is assembled to the spring holding member 3 by appropriately crimping the U-shaped spring plate 4 by using the spring property of the bent portion 4c, as in the case of the conventional means. May be performed. In the spring holding member 3 of the embodiment shown in FIGS. 11 to 32, the main body formed in the shape of a seat plate of the spring plate 4 is provided at the rim of the opening on the front side (the left side in FIG. 12). The concave portion 3b into which the portion 4b fits is formed in a shape corresponding to the contour shape of the main body portion 4b as shown in FIG. 11, and the spring plate 4 is moved first by a pair of operating pieces 4a. In this posture, the operating pieces 4a are inserted from the opening on the front side of the spring holding member 3 so that the spring plate 4 is brought into contact with the front end surface of the spring holding member 3 in the shape of a seat plate. By fitting the portion 4b into the concave portion 3b, assembling and holding are performed.
[0025]
In this example, a lance 41 projecting outward from the metal plate forming the operating piece 4a at the free end side of the operating pieces 4a at an intermediate portion in the width direction of the operating pieces 4a. The operating pieces 4a, 4a are inserted into the lumen of the spring holding member 3 formed in the shape shown in FIGS. 11 to 14, and the lance 41 at the free end thereof is The spring holding member 3 is pressed against the bearing surfaces 3a, 3a formed on the ceiling portion and the bottom plate portion of the lumen of the spring holding member 3 so as to be opposed to the outer peripheral side of the operation pieces 4a, and holds the spring while sliding therewith. When the member 3 is inserted toward the rear side of the lumen, the free end of the member 3 reaches the notches 3c, 3c having a width corresponding to the lance 41 formed on the rear end side of the bearing surface 3a. The lance 41 of the part falls into the notch 3c, and the arc-shaped operating pieces 4a The lance 41 formed at the free end is formed by expanding the support portion 40 formed at the free end by the spring property until it abuts against the bearing surface 3a. As shown in FIG. 15, the escape is prevented by engaging with the front edge of the notch 3c formed in the bearing surface 3a, so that the assembly and holding of the spring plate 4 to the spring holding member 3 are completed. is there.
[0026]
The assembly of the spring plate 4 to the spring holding member 3 by this is further performed by assembling the operating shaft 2 and assembling into the hinge member d, rotating the operating shaft 2 and rotating the shaft portion 22 on the inner end side, thereby When the projecting portions of the arc-shaped operating pieces 4a, 4a pressed against the peripheral surface are pushed in, the operating piece 4a is flattened as shown in FIGS. The lance 41 is separated from the front edge of the window-shaped notch 3c provided on the rear end side of the bearing surface 3a by extending the lance 41. However, in this embodiment, the hinge member d is assembled so that the spring holding member 3 also serves as the case 1, and the case 1 is omitted, and the spring plate 4 is attached to the spring holding member 3 in the form of a seat plate. The main part 4b is a hinge part Since the shaft portion 21 on the outer end side of the operating shaft 2 is located on the front end face (outer end face) of the main shaft 4b and protrudes from the through hole 42 provided in the main body 4b, the assembled hinge member d can be used. The shaft 22 on the outer end of the operating shaft 2 that is inserted into a square hole provided in the body a of the portable telephone A as an electric device and protrudes toward the outer end of the hinge member d is attached to the body a. When the opening / closing lid c is fitted and connected to a square hole provided in the rotating shaft of the opening / closing lid c, the main body 4 b of the spring plate 4 located on the outer end surface of the hinge member d rotates the opening / closing lid c. Since the shaft is pressed against the end face of the shaft portion so as not to move in the axial direction, the arc-shaped operation pieces 4a are crushed by the rotation of the shaft portion 22 on the inner end side of the operation shaft 2. Under load, it does not move in the escape direction and is kept in the assembled state. Brochure states, the state of the binding by assembling the hinge member d.
[0027]
As described above, the spring holding member 3 is formed in a hollow cylindrical shape having an opening on the front side (outer end side), and the spring holding member 3 is provided on the ceiling portion and the bottom wall portion of an empty room formed therein.
