【００１６】
【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。
【００１７】
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、閉塞構造部５により第一部材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る。
【００１８】
また、本発明は、この閉塞構造部５を回動方向に付勢することで、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開放構造部６を設け、この閉塞構造部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の回動を阻止する回動阻止構造部７を設け、この閉塞構造部５に対する回動阻止構造部７の係止を解除する押込みボタン部26を回動阻止構造部７に設けており、この押込みボタン部26を押込み操作した際には、開放構造部６の開放回動付勢作用により第一部材１に対して第二部材２を所定開放角度位置Ｐ３まで自動開放することになる。
【００１９】
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押込みボタン部26を押込み操作することで、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。
【００２０】
ところで、本発明は、第一部材１と第二部材２とを開閉回動自在に枢着するヒンジ装置を、第一部材１と第二部材２との枢着連結部25の左右位置いずれか一方の位置に設けられる第一枢着部25Ａに設けられる第一ヒンジ体Ｈ１と、他方の位置に設けられる第二枢着部25Ｂに設けられる第二ヒンジ体Ｈ２とから成る一対のヒンジ構造（ダブルヒンジ構造）としている。
【００２１】
この構成から、このヒンジ装置Ｈを配設する為の第一部材１と第二部材２との枢着連結部25を左右に分割して且つ各枢着部（第一枢着部25Ａ及び第二枢着部25Ｂ）を小さくすることができ、この左右の枢着部の間（第一枢着部25Ａと第二枢着部25Ｂとの間）に空き部分Ｓができることになるから、この空き部分Ｓが例えば第一部材１内に配設される電子部品と第二部材２内に配設される電子部品とを電気接続する配線を配設するに適した十分なスペースを確保することができる。
【００２２】
【実施例】
図面は本発明の一実施例を図示したものであり、以下に説明する。
【００２３】
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。
【００２４】
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16参照）、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）。
【００２５】
また、本実施例は、第一部材１と第二部材２との枢着連結部25の左右位置いずれか一方の位置に設けられる第一枢着部25Ａに設けられる第一ヒンジ体Ｈ１と、他方の位置に設けられる第二枢着部25Ｂに設けられる第二ヒンジ体Ｈ２とから成り、前記第一部材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る閉塞構造部５を第一ヒンジ体Ｈ１に設けるとともに、この閉塞構造部５を回動方向に付勢することで、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開放構造部６を第二ヒンジ体Ｈ２に設け、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の回動を阻止する回動阻止構造部７を設け、この閉塞構造部５に対する回動阻止構造部７の係止を解除する押込みボタン部26を回動阻止構造部７に設けている。
【００２６】
具体的には、本実施例では、第一部材１の基端左右部位夫々に取付孔１ｂ，１ｃを設け、第二部材２の基端左右部位夫々にもこの取付孔１ｂ，１ｃと連通状態に隣接する取付孔２ｂ，２ｃを設け、この夫々の取付孔から成る第一枢着部25Ａ，第二枢着部25Ｂに軸状パーツとして構成した本発明のヒンジ装置Ｈ（第一ヒンジ体Ｈ１及び第二ヒンジ体Ｈ２）を装着する構成としている。
【００２７】
第一ヒンジ体Ｈ１について説明する。
【００２８】
本体部１（第一部材）には、前記取付孔１ｂを介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２ｂ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良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。
【００２９】
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。
【００３０】
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。
【００３１】
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カム係合部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。
【００３２】
このカム係合部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係合付勢体12としてのコイルバネ12を設けており、このコイルバネ12の先端部は後述する連結部材23に連設され、この連結部材23を介してカム係合部11は係合方向に付勢されている。
【００３３】
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とカム係合部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。）。
【００３４】
また、本体部１に対して重合部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には、カム部10とカム係合部11とは係脱せずに係合状態のまま共同回動することになる。
【００３５】
また、カム係合部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。
【００３６】
本実施例では、このカム部10の頂部とカム係合部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の頂部とカム係合部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後述する回動付勢体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。
【００３７】
つまり、カム部10の頂部とカム係合部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の頂部とカム係合部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。
【００３８】
具体的に説明すると、カム係合部11の頂部に、このカム係合部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とカム係合部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とカム係合部11の頂部11ａの摩擦抵抗を高めている。
【００３９】
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がカム係合部11から係脱してカム部10の頂部10ａとカム係合部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。
【００４０】
更に説明すると、図12に示すように摺動凸条11ｂは、カム係合部11の頂部11ａの内外方向の略中間部に、カム係合部11の中心を中心とした円弧状に形成することで、カム係合部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。
【００４１】
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とカム係合部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。
【００４２】
即ち、本実施例では、カム係合部11がカム部10から係脱してカム係合部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。
【００４３】
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、後述する第二ヒンジ体Ｈ２に設けられる開放構造部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。
【００４４】
具体的には、この回動阻止構造部７は、カム係合部11に設けた係合凹部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を介してケーシング16内で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。
【００４５】
また、係止体８は、カム係合部11に係止した状態では、回動付勢体13によるカム部10とカム係合部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がカム係合部11から係脱した際、回動付勢体13によりカム部10とカム係合部11との共同回動が許容されるように構成し、このカム係合部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カム係合部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とカム係合部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若しくはカム係合部11から係止体８が係脱し得る係止力に構成されている。
【００４６】
具体的には、係止体８は、係合凹部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とカム係合部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、係止体８は係合付勢体22の係合付勢に抗してスライド移動して係合凹部９から係止体８が係脱し得る係止力に構成されている。
【００４７】
また、本実施例は、係合凹部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、この係合凹部９のテーパー面９ａの角度設定によっても係合凹部９に対する係止体８の係止力を適宜構成されている。
【００４８】
また、この回動阻止構造部７は、前記閉塞構造部５に対する係止体８の係止を解除する押込みボタン部26を設けている。
【００４９】
具体的には、この押込みボタン部26は、正面視円形状の押圧部26ａの内面中央位置に軸部26ｂを突設して構成されており、この軸部26ｂは第二連結体４に係る軸状部材18に設けた軸芯孔18ａ内に抜け止め状態に貫通配設されている。
【００５０】
また、押込みボタン部26は、その軸部26ｂが軸状部材18の軸芯孔18ａ内をスライド移動自在に設けられており、この軸部26ｂの先端部26ｂ'は前記係止体８の先端面８ｂに当接するように構成されている。
【００５１】
従って、この押込みボタン部26を押込み操作した際、係止体８は係合付勢体22の係合付勢に抗してスライド移動し、前記カム係合部11に設けた係合凹部９に対する係止が解除されることになる。
【００５２】
第二ヒンジ体Ｈ２について説明する。
【００５３】
本体部１（第一部材）には、前記取付孔１ｃを解して回り止め形状とした第三連結体27の一部を構成する連結部としてのケーシング28を固定し、このケーシング28の一端側に露出状態で配される部材を第四連結体29の一部を構成する取付部30として取付孔２ｃ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28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。
【００５４】
また、前記取付部30の内孔30ａには先端部に回動付勢体13としてのトルクバネ13に連結される連結部材31が回り止め状態で設けられており、この回動付勢体13の他端部はケーシング28の他端部に回り止め状態で配設される連結部材32に連結されており、よって、回動付勢体13がケーシング28を回動させようとする付勢力が、ケーシング28を固定した状態とすることにより、今度は第四連結体29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。
【００５５】
この第二ヒンジ体Ｈ２に係る回動付勢体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、或いは、押込みボタン部26を押込み操作した際、回動付勢体13に付勢されて前述した第一ヒンジ体Ｈ１に係る閉塞構造部５としてのカム部10とカム係合部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。）。
【００５６】
以上の構成から本実施例は次の作用効果を奏する。
【００５７】
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。
【００５８】
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か、或いは、押込みボタン部26を押込み操作すると、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が所定角度の傾斜状態が保持されることになり、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。
【００５９】
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。
【００６０】
先ず、第一ヒンジ体Ｈ１に係る押込みボタン部26を押込み操作することで、図14中矢印ａ方向に係止体８をスライド移動させると、カム部10とカム係合部11とは凹凸係合した状態のまま第二ヒンジ体Ｈ２に係る開放構造部６（回動付勢体13）の開放回動付勢力により共同回動する。この際、係止体８は係合付勢体22によって常に係合付勢されている為、カム部10とカム係合部11とが約１８０°共同回動した後、再びカム係合部11の係合凹部９に係止体８は係合する（図14（ｃ）参照）。
【００６１】
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15中矢印ｄ方向に第二連結体４を回動させると、カム係合部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、カム係合部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15中ａ方向に後退して、カム部10とカム係合部11とが完全に係脱する（図15（ａ），（ｂ）参照）。その後、更に第二連結体４を図15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とカム係合部11とが落ち込み係合するまでの間は、カム部10の頂部10ａとカム係合部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とカム係合部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15（ｃ）参照）。
【００６２】
次に、本体部１に対して重合部２を手動で開放させた場合におけるヒンジ装置Ｈの動作について説明する。
【００６３】
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、第二連結体４を回動させると、カム部10とカム係合部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とカム係合部11とが完全に係脱するよりも前にカム係合部11の係合凹部９から係止体８が後退しながら完全に係脱し、回動付勢体13に付勢されて結局はカム部10とカム係合部11とは係合状態のまま共同回動し、その後、再び係合付勢体22に付勢される係止体８が前進して係合凹部９へ嵌挿係止することになる。
【００６４】
このカム部10とカム係合部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、カム係合部11の係合凹部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。
【００６５】
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、第二連結体４を回動させると、カム係合部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（本体部１に対して重合部２を閉塞方向に回動させる方向、即ち、このカム部10だけが回動する方向へのカム部10とカム係合部11との凹凸係合は、この係合力よりも回動付勢体13の回動付勢が勝るようにカム面設定が成されていることで、このカム係合部11が共同回動せずに回動停止した状態となる為、該カム係合部11からカム部10が係脱して回動することになる。）。この際、カム係合部11及び係止体８が係合付勢体12（及び係合付勢体22）に抗して後退して、カム部10とカム係合部11とが完全に係脱する。その後、更に第二連結体４を回動付勢体13の付勢に抗して回動させ、再びカム部10とカム係合部11とが落ち込み係合するまでの間は、カム部10の頂部10ａとカム係合部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とカム係合部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。
【００６６】
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たり、或いは、押込みボタン部26を押込み操作すると、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。
【００６７】
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できることになり、より一層実用的である。
【００６８】
また、本実施例は、本体部１と重合部２との枢着連結部25に配設されるヒンジ装置Ｈとして、閉塞構造部５及び回動阻止構造部７を具備する第一ヒンジ体Ｈ１と、開放構造部６を具備する第二ヒンジ体Ｈ２とからなるヒンジ構造（ダブルヒンジ構造）としたから、このヒンジ装置Ｈを配設するための本体部１と重合部２との枢着連結部25を左右に分割して且つ各枢着部（第一枢着部25Ａ及び第二枢着部25Ｂ）を小さくすることができ、この左右の枢着部の間（第一枢着部25Ａと第二枢着部25Ｂとの間）に空き部分Ｓができることになるから、この空き部分Ｓが本体部１内に配設される電子部品と重合部２内に配設される電子部品とを電気接続する配線を配設するに適した十分なスペースを確保することができるなどの効果が得られる。

In the combined state, the joint is rotated by the opening rotation biasing force of the opening structure portion 6 (the rotation biasing body 13) related to the second hinge body H2. At this time, since the locking body 8 is always urged and engaged by the engagement urging body 22, after the cam portion 10 and the cam engagement portion 11 jointly rotate about 180 °, the cam engagement portion again. The locking body 8 engages with the 11 engaging recesses 9 (see FIG. 14C).
[0061]
Subsequently, when the second connecting body 4 is rotated in the direction of the arrow d in FIG. 15 by rotating the overlapping section 2 in the closing direction with respect to the main body section 1, the cam engaging section 11 becomes the locking body 8. Only the cam portion 10 is locked and held by the rotation. At this time, the cam engaging portion 11 and the locking body 8 retreat in the direction a in FIG. 15 against the engagement biasing body 12 (and the engagement biasing body 22), and the cam portion 10 and the cam engagement Part 11 is completely disengaged (see FIGS. 15A and 15B). Thereafter, the second connecting body 4 is further rotated against the urging force of the rotating urging body 13 in the direction of the arrow d in FIG. 15 until the cam portion 10 and the cam engaging portion 11 are again engaged with each other. During this time, a free-stop action due to frictional resistance occurs between the top portion 10a of the cam portion 10 and the top portion 11a of the cam engagement portion 11, and after passing through this free stop region, the engagement biasing body 12 is attached. As a result, the cam portion 10 and the cam engaging portion 11 are engaged with each other by dropping, so that a closing urging rotational force is generated, so that the overlapping portion 2 is completely closed in the main body portion 1 (FIG. 15C). reference).
[0062]
Next, the operation of the hinge device H when the overlapping portion 2 is manually opened with respect to the main body portion 1 will be described.
[0063]
First, when the second connecting body 4 is rotated by rotating the overlapping portion 2 in the opening direction with respect to the main body portion 1, the cam portion 10 and the cam engaging portion 11 are engaged and disengaged. Move. At this time, before the cam portion 10 and the cam engaging portion 11 are completely engaged / disengaged, the locking body 8 is completely disengaged while being retracted from the engaging recess 9 of the cam engaging portion 11 and is attached with a rotation. As a result, the cam body 10 and the cam engaging section 11 are jointly rotated while being engaged, and then the locking body 8 is again urged by the engagement biasing body 22. It moves forward and engages and locks into the engaging recess 9.
[0064]
Until the cam portion 10 and the cam engagement portion 11 are completely engaged and disengaged, a closing rotation biasing force that biases the overlapping portion 2 in the closing direction is generated with respect to the main body portion 1. After the engaging body 8 is completely engaged and disengaged from the 11 engaging recesses 9, an opening rotation biasing force that biases the overlapping portion 2 in the opening direction with respect to the main body portion 1 is generated.
[0065]
Subsequently, when the second connecting body 4 is rotated by rotating the overlapping portion 2 in the closing direction with respect to the main body 1, the cam engaging portion 11 is locked and held by the locking body 8. 10 is rotated (the direction in which the overlapping portion 2 is rotated in the closing direction with respect to the main body portion 1, that is, the cam portion 10 and the cam engaging portion 11 in the direction in which only the cam portion 10 is rotated). In the concave / convex engagement, the cam surface is set so that the rotation urging force of the rotation urging body 13 is greater than the engagement force. Since the movement is stopped, the cam portion 10 is engaged with and disengaged from the cam engagement portion 11). At this time, the cam engagement portion 11 and the locking body 8 are retracted against the engagement biasing body 12 (and the engagement biasing body 22), and the cam portion 10 and the cam engagement portion 11 are completely separated. Disengage. After that, the second connecting body 4 is further rotated against the urging force of the rotation urging body 13 until the cam portion 10 and the cam engagement portion 11 are engaged again by being lowered. A free stop action due to frictional resistance occurs between the top portion 10a of the cam engaging portion 11 and the top portion 11a of the cam engaging portion 11, and after passing through this free stop region, the engaging biasing member 12 urges the cam portion 10 to When the cam engagement portion 11 is depressed and engaged, a closing urging rotational force is generated, so that the overlapping portion 2 is completely closed to the main body portion 1.
[0066]
Therefore, according to the present embodiment, in use, for example, by putting a finger between the main body 1 and the overlapping portion 2 with a hand holding a telephone, the overlapping portion 2 is rotated in the opening direction with respect to the main body 1. If the push button part 26 is pushed or operated, the overlapping part 2 is automatically opened by the opening and turning biasing action, and the opening operation of the overlapping part 2 can be performed easily and quickly. Is.
[0067]
Further, in this embodiment, the rotation range A2 from the position P3 where the overlapping portion 2 is opened to the maximum with respect to the main body 1 by the opening rotation biasing action to the predetermined opening angle position P2 where the overlapping portion 2 is rotated in the closing direction. In the present invention, since the free stop action for holding the second member 2 at an arbitrary opening angle position with respect to the first member 1 is generated, the desired overlapping portion 2 can be easily used with respect to the main body portion 1. It can be used after being stopped at an angle, and is even more practical.
[0068]
Further, in this embodiment, the first hinge body H1 including the closing structure portion 5 and the rotation prevention structure portion 7 as the hinge device H disposed in the pivot joint portion 25 between the main body portion 1 and the overlapping portion 2.
