【００１０】
また、前記係止体８を嵌挿係止し得る係止凹部９を前記カム部10若しくは係合カム部11に設け、この係止凹部９に嵌挿する係止体８の嵌挿部にテーパー面８ａを形成することで、この係止凹部９に対する係止体８の係止力は、第一部材１に対して第二部材２を前記カム部10と係合カム部11とによる閉塞回動付勢力に抗して前記所定開放角度位置Ｐ２よりも開放方向に手動で回動させた際、カム部10若しくは係合カム部11から係止体８が係脱し得る係止力に構成されていることを特徴とする請求項２，３のいずれか１項に記載のヒンジ装置に係るものである。
【００１１】
また、請求項１〜４のいずれか１項に記載のヒンジ装置を枢着部に設けたことを特徴とするヒンジ装置を用いた電子機器に係るものである。
【００１２】
【発明の実施の形態】
好適と考える本発明の実施の形態（発明をどのように実施するか）を、図面に基づいてその作用効果を示して簡単に説明する。
【００１３】
本発明は、第一部材１に対して重合閉塞状態の第二部材２を開放させた際、重合閉塞位置Ｐ１から開放方向に回動させた所定開放角度位置Ｐ２までの回動域Ａ１においては、第一部材１に対して第二部材２を重合閉塞位置Ｐ１まで自動閉塞させる閉塞回動付勢作用が生じ、また、第一部材１に対して第二部材２を前記所定開放角度位置Ｐ２よりも開放方向に手動で回動させた際、第一部材１に対して第二部材２を所定開放角度位置Ｐ３まで自動開放させる開放回動付勢作用が生じることになる。
【００１４】
即ち、第一部材１に対して第二部材２を所定開放角度位置Ｐ２よりも開放方向に手動で回動させると、第二部材２は所定開放角度位置Ｐ３まで自動開放することになる。
【００１５】
従って、本発明に係るヒンジ装置を、例えば前述した本体部と重合部とを枢着連結して成る折り畳みタイプの携帯式電子機器に適用した場合、使用する際、例えば電話機を持つ手で本体部と重合部との間に指を入れることで、本体部に対して重合部を開放方向に回動させると、重合部は開放回動付勢作用により自動開放することになるなど、重合部の開放操作が簡易且つ迅速に行えることになり極めて実用的である。
【００１６】
また、第一部材１に対して第二部材２を開放させた位置から閉塞方向に回動させた前記所定開放角度位置Ｐ２までの回動域Ａ２においては、第一部材１に対して第二部材２を任意の開放角度位置で保持するフリーストップ作用が生じるように構成した場合には、第一部材１に対して第二部材２を使い易い所望の角度で停止させて使用することが出来ることになり、より一層実用的である。
【００１７】
【実施例】
本発明の具体的な実施例について図面に基づいて説明する。
【００１８】
本実施例は、図１に示すように折り畳みタイプの携帯電話機に適用した場合を示したもので、操作部14を備えた本体部を第一部材１とし、表示画面15を備えた重合部を第二部材２とし、第一部材１と第二部材２とが重合した閉塞状態から第二部材２を例えば１２０度まで回動した開放状態（通話状態）とすることができる枢着構造に本発明のヒンジ装置Ｈを適用している。
【００１９】
そして、第一部材１に対して重合閉塞状態の第二部材２を開放させた際、重合閉塞位置Ｐ１から開放方向に回動させた所定開放角度位置Ｐ２までの回動域Ａ１においては、第一部材１に対して第二部材２を重合閉塞位置Ｐ１まで自動閉塞させる閉塞回動付勢作用が生じ（図15参照）、第一部材１に対して第二部材２を前記所定開放角度位置Ｐ２よりも開放方向に手動で回動させた際、第一部材１に対して第二部材２を一挙に所定開放角度位置Ｐ３（最大開放角度位置）まで自動開放させる開放回動付勢作用が生じ、しかも、この第一部材１に対して第二部材２を開放させた位置から閉塞方向に回動させた前記所定開放角度位置Ｐ２までの回動域Ａ２においては、この第二部材２から手を離すと、その離した位置で第二部材２は停止し、ふらつくことがないフリーストップ状態を実現した構成としている（図16参照）。
【００２０】
具体的には、本実施例では、第一部材１の基部に取付孔１ａを設け、第二部材２の基部にもこの取付孔１ａと連通状態に隣接する取付孔２ａを設け、この夫々の取付孔１ａ，２ａに軸状パーツとして構成した本発明のヒンジ装置Ｈを装着する構成としている。
【００２１】
本体部１（第一部材）には、前記取付孔１ａを解して回り止め形状とした第一連結体３の一部を構成する連結部としてのケーシング16を固定し、このケーシング16の一端側に露出状態で配される部材を第二連結体４の一部を構成する取付部17として取付孔２ａを介して重合部２（第二部材）に回り止め状態に固定している。このケーシング16は、図示したように断面八角形状としているが、これは本体部１に対する堅固な回り止め固定を達成するための構成であると共に、この回り止め構造を備えながら内部に効率よく部品を収納し得る形状としての八角形状を採用している。
【００２２】
また、前記取付部17の内孔17ａには先端部にカム部10が設けられた第二連結体４を構成する軸状部材18が回り止め状態で設けられている。
【００２３】
この第二連結体４に係る軸状部材18は、先端部のカム部10が第一連結体３に係るケーシング16内に配される構成としている。
【００２４】
第一連結体３に係るケーシング16の他端側には閉塞部材19が配設され、更に、ケーシング16内には、前記第二連結体４に係るカム部10と対向し、互いに凹凸係合する係合カム部11を有する係合部材20が設けられており、この係合部材20は、ケーシング16内に回動自在に設けると共に、ケーシング16内を係合離反方向にスライド移動自在に設けられている。
【００２５】
この係合カム部11を有する係合部材20と閉塞部材19との間のケーシング16内には、係合方向に付勢するコイルバネ12を係合付勢体12として設けている。
【００２６】
この係合付勢体12により、本体部１に対して重合閉塞状態の重合部２を開放させた際、重合閉塞位置Ｐ１から開放方向に回動させた所定開放角度位置Ｐ２までの回動域Ａ１においては、係合付勢体12に付勢されてカム部10と係合カム部11とが落ち込み係合しようとすることで、本体部１に対して重合部２を重合閉塞位置Ｐ１まで自動閉塞させる閉塞回動付勢作用が生じるように構成されている（これが、請求項で言う閉塞構造部５である。）。
【００２７】
一方、カム部10を有する軸状部材18には、トルクバネ13を回動付勢体13として設けており、この回動付勢体13の他端部はケーシング16内に回り止め状態で配設される連結部材21に連結されており、よって、回動付勢体13がケーシング16を回動させようとする付勢力が、ケーシング16を固定した状態とすることにより、今度は軸状部材18（カム部10）を回動させる付勢力として機能するように構成されている。
【００２８】
この回動付勢体13により、本体部１に対して重合部２を所定開放角度位置Ｐ２よりも開放方向に手動で回動させた際、回動付勢体13に付勢されて閉塞構造部５としてのカム部10と係合カム部11とが係脱せずに係合状態のまま共同回動することで、本体部１に対して重合部２を所定開放角度位置Ｐ３まで自動開放させる開放回動付勢作用が生じるように構成されている（これが、請求項で言う開閉構造部６である。）。
【００２９】
また、係合カム部11は、１８０度対称位置にＶ字状の凹部を形成し、この凹部を前記カム部10が係合する係合部分とし、係脱状態となる領域ではこの凹部間の頂部（先端面部）にカム部10の頂部（先端面部）が係合付勢体12による押圧力により圧接する構成としている。
【００３０】
本実施例では、このカム部10の頂部と係合カム部11の頂部との摩擦抵抗が高くなる摩擦抵抗増大手段を設けて、このカム部10の頂部と係合カム部11の頂部とが突合せ当接した際には、係合付勢体12による押圧力と摩擦抵抗増大手段とによる回動抵抗の増大によって回動付勢体13の回動付勢が作用していても手で動かさない限り停止保持されるように構成している。
【００３１】
つまり、カム部10の頂部と係合カム部11の頂部との当接面積を大きく形成することで、係合付勢体12の付勢力によって押圧当接するこのカム部10の頂部と係合カム部11の頂部との摩擦抵抗を高めてフリーストップを実現する摩擦抵抗増大手段を構成している。本実施例では、本体部１に対して重合部２を最大開放させた位置から閉塞方向に回動させた前記所定開放角度位置Ｐ２までの回動域Ａ２において、本体部１に対して重合部２を任意の開放角度位置で保持するフリーストップ作用が生じるように構成している。
【００３２】
具体的に説明すると、係合カム部11の頂部に、この係合カム部11の回動方向に長さを有する摺動凸条11ｂを設け、この摺動凸条11ｂが嵌合当接する摺動凹溝10ｂを前記カム部10に設けることで、このカム部10の頂部10ａと係合カム部11の頂部11ａとの当接面積を大きくし、このカム部10の頂部10ａと係合カム部11の頂部11ａの摩擦抵抗を高めている。
【００３３】
また、本実施例では、係合カム11の頂部11ａの略全範囲に、この頂部11ａの回動方向に長さを有する前記摺動凸条11ｂを設けて、前記カム部10が係合カム部11から係脱してカム部10の頂部10ａと係合カム部11の頂部11ａとが当接する略全ての回動領域でこの摺動凸条11ｂが摺動凹溝10ｂに突き当たり状態で嵌合当接するように構成している。
【００３４】
更に説明すると、図12に示すように摺動凸条11ｂは、係合カム部11の頂部11ａの内外方向の略中間部に、係合カム部11の中心を中心とした円弧状に形成することで、係合カム部11の頂部11ａの回動方向に長さを有する凸条に構成している。
【００３５】
また、摺動凸条11ｂと摺動凹溝10ｂとは、嵌合時に略全面部が当接する凹凸形状に形成し、これによるカム部10の頂部10ａと係合カム部11の頂部11ａとの当接面積の増大により摩擦抵抗を高めて極めて良好なフリーストップを実現できるようにしている。
【００３６】
即ち、本実施例では、係合カム部11がカム部10から係脱して係合カム部11の頂部11ａとカム部10の頂部10ａとが当接する略全ての回動領域で極めて良好なフリーストップ作動が発揮されるように構成している。
【００３７】
また、本実施例では、前述した閉塞構造部５に係脱自在に係止して開放構造部６による閉塞構造部５の開放方向への回動を阻止する回動阻止構造部７を設けている。
【００３８】
具体的には、この回動阻止構造部７は、係合カム部11に設けた係止凹部９に係脱自在に嵌挿係止し得る係止体８を第一連結体３を構成するケーシング16に設けて構成されており、この係止体８は、連結部材23を介して回り止め状態にして係合離反方向にスライド移動自在に設けると共に、この係合方向に付勢するコイルバネ22としての係合付勢体22により係合方向に付勢されている。
【００３９】
また、係止体８は、係合カム部11に係止した状態では、回動付勢体13によるカム部10と係合カム部11との共同回動が阻止されるように構成するとともに、この係止体８が係合カム部11から係脱した際、回動付勢体13によりカム部10と係合カム部11との共同回動が許容されるように構成し、このカム部10若しくは係合カム部11に対する係止体８の係止力は、回動付勢体13の付勢力によっては係合カム部11から係止体８は係脱せず、本体部１に対して重合部２をカム部10と係合カム部11とによる閉塞回動付勢力に抗して所定開放角度位置Ｐ２よりも開放方向に手動で回動させた際、カム部10若しくは係合カム部11から係止体８が係脱し得る係止力に構成されている。
【００４０】
具体的には、係止体８は、係止凹部９に嵌挿する先端嵌挿部にテーパー面８ａが形成されており、このテーパー面８ａの角度設定により、本体部１に対して重合部２をカム部10と係合カム部11とによる閉塞回動付勢力に抗して所定開放角度位置Ｐ２よりも開放方向に手動で回動させた際、係止凹部９から係止体８が係脱し得る係止力に構成されている。
【００４１】
また、本実施例は、係止凹部９の内面９ａにして係止体８のテーパー面８ａが当接する当接面もテーパー面９ａに構成されており、この係止凹部９のテーパー面９ａの角度設定によっても係止凹部９に対する係止体８の係止力を適宜構成されている。
【００４２】
本実施例は上述のように構成したから、本体部１に対して重合閉塞状態の重合部２を開放させた際、重合閉塞位置Ｐ１から開放方向に回動させた所定開放角度位置Ｐ２までの回動域Ａ１においては、本体部１に対して重合部２を重合閉塞位置Ｐ１まで自動閉塞させる閉塞回動付勢作用が生じ、また、本体部１に対して重合部２を所定開放角度位置Ｐ２よりも開放方向に手動で回動させた際、本体部１に対して重合部２を所定開放角度位置Ｐ３まで自動開放させる開放回動付勢作用が生じ、この本体部１に対して重合部２を開放させた位置から閉塞方向に回動させた所定開放角度位置Ｐ２までの回動域Ａ２においては、本体部１に対して重合部２を任意の開放角度位置で保持するフリーストップ作用が生じる。
【００４３】
即ち、本体部１に対して重合部２を所定開放角度位置Ｐ２よりも開放方向に手動で回動させると、重合部２は所定開放角度位置Ｐ３まで自動開放することになり、この所定開放角度位置Ｐ３まで開放状態とした重合部２を閉塞方向へ回動させると所定開放角度位置Ｐ２までの回動域Ａ２においては、常に本体部１に対して重合部２が保持状態となり、所定開放角度位置Ｐ２を過ぎると、重合閉塞位置Ｐ１まで重合部１は自動閉塞することになる。
【００４４】
この際におけるヒンジ装置Ｈの動作について図面を基に説明する。
【００４５】
先ず、本体部１に対して重合部２を開放方向に回動させることで、図13中矢印ａ方向に第二連結体４を回動させると、カム部10と係合カム部11とは係脱しようとしながら共同回動する。この際、カム部10と係合カム部11とが完全に係脱するよりも前に係合カム部11の係止凹部９から係止体８が図13中矢印ｂ方向に後退しながら完全に係脱し（図13（ａ），（ｂ）参照）、回動付勢体13に付勢されてカム部10と係合カム部11とは係合状態のまま図13中矢印ａ方向に共同回動し、その後、再び係合付勢体22に付勢される係止体８が図13中ｃ方向に前進して係止凹部９へ嵌挿係止することになる（図13（ｃ）参照）。
【００４６】
このカム部10と係合カム部11とが完全に係脱するまでは、本体部１に対して重合部２を閉塞方向へ付勢する閉塞回動付勢力が生じており、係合カム部11の係止凹部９から係止体８が完全に係脱した後は、本体部１に対して重合部２を開放方向へ付勢する開放回動付勢力が生じている。
【００４７】
続いて、本体部１に対して重合部２を閉塞方向に回動させることで、図14中矢印ｄ方向に第二連結体４を回動させると、係合カム部11は係止体８により係止保持されカム部10だけが回動する。この際、係合カム部11及び係止体８が係合付勢体12（及び係合付勢体22）に抗して図14中ｂ方向に後退して、カム部10と係合カム部11とが完全に係脱する（図14（ａ），（ｂ）参照）。その後、更に第二連結体４を図14中矢印ｄ方向に回動付勢体13の付勢に抗して回動させ、再びカム部10と係合カム部11とが落ち込み係合するまでの間は、カム部10の頂部10ａと係合カム部11の頂部11ａとの間に摩擦抵抗によるフリーストップ作用が生じ、このフリーストップ領域を過ぎた後は、係合付勢体12に付勢されてカム部10と係合カム部11とが落ち込み係合することで閉塞付勢回動力が生じ、よって、重合部２は本体部１に完全に閉塞状態となる（図14（ｃ）参照）。
【００４８】
よって、本実施例によれば、使用に際し、例えば電話機を持つ手で本体部１と重合部２との間に指を入れることで、本体部１に対して重合部２を開放方向に回動させると、重合部２は開放回動付勢作用により自動開放することになるなど、重合部２の開放操作が簡易且つ迅速に行えることになり極めて実用的である。
【００４９】
また、本実施例は、本体部１に対して重合部２を開放回動付勢作用により最大限開放させた位置Ｐ３から閉塞方向に回動させた所定開放角度位置Ｐ２までの回動域Ａ２においては、第一部材１に対して第二部材２を任意の開放角度位置で保持するフリーストップ作用が生じるように構成されているから、本体部１に対して重合部２を使い易い所望の角度で停止させて使用することが出来ることになり、より一層実用的である。
【００５０】
尚、本発明は、本実施例に限られるものではなく、各構成要件の具体的構成は適宜設計し得るものである。
【００５１】
