【発明の属する技術分野】
本発明は、パチンコ機の外枠に内枠を開閉可能に取り付ける内枠取付用ヒンジに関し、特に、ヒンジ軸支持部材に回動支軸を設け、ヒンジ軸受部材に軸孔と軸誘導部とを設けることにより、前記回動支軸が前記軸誘導部に当接されつつ軸孔に案内されるため、ロック部材等を必要とせず、且つ横方向からの組み付けが可能になると共に、前記回動支軸が軸孔に挿入されるため、内枠の該回動支軸の軸方向の着脱が可能な内枠取付用ヒンジに関するものである。
【０００２】
【従来の技術】
従来より、パチンコ機の外枠に内枠を開閉可能に取り付ける内枠取付用ヒンジに関し、外枠の所定位置に内枠の取り付け、取り外しを容易に行うことが可能な内枠取付用ヒンジが種々提案されている。
【０００３】
例えば、特開平８−２１５３９５号公報に記載のパチンコ機の蝶着装置においては、外枠と前枠の一側縁を開閉自在に蝶着する上下二組の蝶着体からなり、両蝶着体は、外枠に止着する上固定部材及び下固定部材と、前枠に支着する上回動部材及び下回動部材とを有し、上下蝶着体の何れか一方の固定部材には、厚さ方向に弾性を有すると共に嵌着孔を開設した弾着部材の基端側を設け、上記一方の固定部材に対応する回動部材には、上記嵌着孔に挿入可能な第１回動支軸を突設し、上記一方の固定部材または弾着部材の先端側には、上記第１回動支軸を嵌着孔に誘導する誘導手段を形成し、他方の固定部材には第２回動支軸を形成すると共に、対応する回動部材には軸孔を形成し、上記第２回動支軸を軸孔に挿入すると共に、上記第１回動支軸を弾着部材の弾性に抗して誘導手段により嵌着孔方向に押し込むことにより、上記第１回動支軸を嵌着孔に嵌合させて回動自在に蝶着するように構成されている。
【０００４】
これにより、固定部材または弾着部材に形成した誘導手段によって、回動部材に形成した回動支軸を弾着部材に開設した嵌着孔に誘導して嵌合させることができ、固定部材と回動部材とを回動自在に軸着し、弾着部材の弾性変形によって回動支軸を着脱自在とすることができる。
【０００５】
【発明が解決しようとする課題】
しかしながら、前記特開平８−２１５３９５号公報に記載されたパチンコ機の蝶着装置では、第１回動支軸を弾着部材の弾性に抗して誘導手段により嵌着孔方向に押し込むことにより、上記第１回動支軸は嵌着孔に嵌合されて回動自在に蝶着される。このため、この第１回動支軸が突設される回動部材は、その第１回動支軸の軸方向に弾着部材が存在し、その軸方向に着脱できないため、製造ラインの組み付け用装置による内枠の取り付けが困難になるという問題がある。また、前記弾着部材の金属疲労等による破壊のため、内枠の不意の落下事故の発生するおそれがあると共に、蝶着装置の弾性部材等の構成部品点数が多く製造コストアップになるという問題がある。
【０００６】
そこで、本発明は、上述した問題点を解決するためになされたものであり、ヒンジ軸支持部材に回動支軸を設け、ヒンジ軸受部材に軸孔と軸誘導部とを設けることにより、前記回動支軸が横方向から前記軸誘導部に当接されつつ軸孔に案内されて、この軸孔に挿入されるため、回動支軸の横方向への外れ防止用弾性部材やロック部材等を無くすことが可能となると共に、前記回動支軸が軸孔に挿入されるため、内枠の該回動支軸の軸方向の着脱が可能な内枠取付用ヒンジを提供することを目的とする。
【０００７】
【課題を解決するための手段】
前記目的を達成するために、請求項１に係る内枠取付用ヒンジは、パチンコ機の一方の側部の上方に配設されて、前記側部の下方に配設される下ヒンジと協働して外枠に内枠を開閉可能に取り付ける内枠取付用ヒンジにおいて、前記内枠取付用ヒンジは、ヒンジ軸支持部材と、ヒンジ軸受部材とを備え、前記ヒンジ軸支持部材は、鉛直方向に立設されると共に先端側に先細りのテーパー面が形成された回動支軸を有し、前記ヒンジ軸受部材は、前記回動支軸が挿入される軸孔と、前記軸孔に該回動支軸を誘導する軸誘導部とを有し、前記軸誘導部は、前記軸孔から連続して形成され、且つ、前記回動支軸の軸径よりも狭い溝幅として形成された切欠き溝と、前記切欠き溝につながった前記回動支軸の軸径よりも狭い溝幅の部位と前記狭い溝幅の部分から外側に傾斜しながら溝幅が広がった部位を有す案内溝部とからなり、前記ヒンジ軸受部材は、前記回動支軸の先端が、前記案内溝部の広がった部位に当接させた状態で前記軸孔側に押し込まれるにつれて前記回動支軸の軸径よりも狭い溝幅の部位に案内されてから、該回動支軸の先端に形成された前記テーパー面が前記切欠き溝を摺接移動して、該回動支軸が前記軸孔に挿入されて前記ヒンジ軸支持部材に蝶着されることを特徴とする。
【０００８】
このような特徴を有する請求項１に係る内枠取付用ヒンジにおいては、軸誘導部は、軸孔から連続して形成され、且つ、回動支軸の軸径よりも狭い溝幅として形成された切欠き溝と、この切欠き溝につながった回動支軸の軸径よりも狭い溝幅の部位と、その狭い溝幅の部分から外側に傾斜しながら溝幅が広がった部位を有す案内溝部とから形成されているため、横方向からこの案内溝部の端縁を容易に回動支軸の先端に当接することが可能となり、横方向から内枠を取り付ける作業を容易に行うことが可能となる。
また、案内溝部は、回動支軸に最初に当接する部分の溝幅が、切欠き溝側の溝幅よりも広くなるように形成されているため、回動支軸をこの案内溝部に正確な位置決めをすることなく、容易に案内溝部の中央部側に寄せつつ、切欠き溝へ案内することが可能となり、組み付け作業の作業性向上を図ることが可能となる。
また、回動支軸の軸径よりも狭い溝幅の切欠き溝が、案内溝部から軸孔まで連続して形成されているため、内枠取り付け時に、回動支軸の先端側に形成されるテーパー面等がこの切欠き溝に入って摺接移動して軸孔に挿入されるの目視確認でき、確実に内枠を横方向から取り付けることが可能となると共に、作業不良を無くすることが可能となる。
また、この回動支軸の軸孔から横方向への外れを防止するためのロック部材等が必要ないため、機械的故障や内枠の不意の落下等のおそれを無くすことが可能となると共に、ロック部材等の部品点数の削減が可能となるため、製造コストの削減を図ることが可能となる。さらに、回動支軸は軸孔に挿入されることから、内枠がこの回動支軸の軸方向に着脱可能となるため、製造ラインの組み付け用装置による内枠の取り付けができ、製造ラインにおける作業性や生産性の向上を図ることが可能となる。

【発明の実施の形態】
以下、本発明に係る内枠取付用ヒンジについて、具体化した第１乃至第３の実施形態を図面を参照して詳細に説明する。先ず、第１実施形態に係る内枠取付用ヒンジが設けられるパチンコ機の全体構成について図１に基づいて説明する。図１は第１実施形態に係る内枠取付用ヒンジが設けられるパチンコ機の全体を示した正面図である。
【００１６】
このパチンコ機１は、図１に示すように、内枠２が内枠取付用ヒンジ１２及び下ヒンジ１１を介して外枠４に対して開閉自在に取り付けられている。そして、この内枠２のほぼ中央部には、遊技盤（不図示）の前側を被覆する鋼板やステンレス等の金属製のガラス扉５が左側端部を軸で支えられて開閉自在に取り付けられている。ガラス扉５には開口部を有する鋼板やステンレス等の金属製のガラス保持枠がスポット溶接等により固着されており、該ガラス保持枠に装着された２枚のガラスを通して遊技領域が見えるようになっている。また、このガラス扉５の上端縁部の前面には、ランプカバー５Ａが設けられ、この中には４個の装飾用ランプが内蔵されている。これらのランプカバー５Ａ及び装飾用ランプ等により電気的機器である装飾表示機器が構成され、遊技中のエラー表示や「当たり」表示等が表示される。
このランプカバー５Ａは、前面側に突出するように膨出状の形状とされ、透明又は半透明で、内蔵された装飾用ランプの点灯光を透過可能である。また、ランプカバー５Ａの表面にはカラフルな色彩が施されていてもよい。また、内枠２の右側中央部には、ガラス扉５を施錠する施錠装置（不図示）を操作するための鍵挿入部６が設けられている。ガラス扉５を開くためには、この鍵挿入部６に所定のキーを挿入して所定方向に回せば、施錠装置のロック状態が解除されて、ガラス扉５のみがオープンされる。
【００１７】
また、このガラス扉５の下側には賞球を受ける上皿７がスピーカ８を内蔵して左側端部を軸で支えられて開閉自在に設けられている。この上皿７は、内枠２の右内側面に設けられた施錠装置（不図示）により施錠されている。この上皿７を開くためには、先ず、ガラス扉５をオープンした後、上皿７の裏側に設けられているロック解除レバー（不図示）を押し下げることにより、上皿７の施錠装置のロック状態が解除されて、上皿７がオープンされる。
そして、この上皿７の下には、下部受皿９が設けられる。また、上皿７に連通する不図示の球送り機構を介して上皿７のパチンコ球がハンドル１０に連結された不図示の発射装置へ送られるよう構成されている。
【００１８】
次に、内枠２の外枠４への取り付けについて図２に基づいて説明する。図２は第１実施形態に係るパチンコ機１の外枠４への内枠２の取り付けを示す左側面図である。
ここで、内枠２は、内枠取付用ヒンジ１２及び下ヒンジ１１によって、外枠４に開閉可能に取り付けられている（図１参照）。この下ヒンジ１１は、外枠４の前面開口部の左下角部の内面にネジ止め等により固定される下固定部材１１Ａと、内枠２の左角下端面にネジ止めにより固定される下回動部材１１Ｂとから構成されている。前記下固定部材１１Ａは、略Ｌ字形に折り曲げられる金属製の部材であって、下面板が外枠４の前面よりも延出され、その前縁部に先端部にテーパー面が形成された下回動支軸１３がカシメ等によりほぼ垂直に設けられている。また、前記下回動部材１１Ｂは、略Ｌ字形に折り曲げられる金属製の部材であって、下面板が内枠２の前面よりも延出され、その前縁部に前記下回動支軸１３を挿通する下軸孔１４が形成されている。
また、内枠取付用ヒンジ１２は、外枠４の左上角部にネジ止め等により固定される後述のヒンジ軸支持部材１２Ａ（図３参照）と、内枠２の左上角部にネジ止め等により固定される後述のヒンジ軸受部材１２Ｂ（図４参照）とから構成されている。
【００１９】
そして、図２に示すように、内枠２の外枠４への取り付けは、先ず、内枠２を外枠４の前面側に開いた状態に位置させると共に、少し後傾させつつ、下回動部材１１Ｂの下軸孔１４を、外枠４の左下に固定されている下固定部材１１Ａの下回動支軸１３に入れる。続いて、内枠２を矢印１５の方向、即ち外枠４の左上角部の方向に押し込むことにより、後述のように、外枠４のヒンジ軸支持部材１２Ａに内枠２のヒンジ軸受部材１２Ｂが係合する（図５参照）。これにより、内枠２は、内枠取付用ヒンジ１２及び下ヒンジ１１によって、外枠４に開閉可能に取り付けられる。
【００２０】
次に、外枠４の左上角部にネジ止め等により固定されるヒンジ軸支持部材１２Ａについて図３に基づいて説明する。図３は第１実施形態に係るヒンジ軸支持部材１２Ａを示す図で、（ａ）は平面図、（ｂ）は側面図である。
図３に示すように、ヒンジ軸支持部材１２Ａは、略Ｌ字形に折り曲げられた金属製の部材であって、外枠４の厚さ寸法とほぼ同じ幅寸法の折曲部２０、２１には、各々ネジ止め用の皿孔２２が２箇所ずつ形成されている。そして、外枠４の側面に当接される折曲部２１は、外枠４の前面側に延出されると共に、上部が略Ｌ字形に内側（図３（ａ）中、上方向）へ折り曲げられて、軸取付部２３が形成されている。そして、この軸取付部２３の前縁部上面に回動支軸１６がカシメ等によりほぼ垂直（図３（ｂ）中、上方向）に固定されている。また、この回動支軸１６の先端部にはテーパー面１６Ａが形成されている。
そして、前記折り曲げ部２０が外枠４の左上角部上端面にネジ止めされ、折り曲げ部２１が外枠４の左上角部側面にネジ止めされて、回動支軸１６は外枠４の左上角部前側に位置するようになる（図２参照）。
【００２１】
次に、内枠２の左上角部にネジ止め等により固定されるヒンジ軸受部材１２Ｂについて図４に基づいて説明する。図４は第１実施形態に係るヒンジ軸受部材１２Ｂを示す図で、（ａ）は平面図、（ｂ）は側面図である。
図４に示すように、ヒンジ軸受部材１２Ｂは、断面略コの字形に折り曲げられた金属製の部材であって、内枠２の厚さ寸法とほぼ同じ幅寸法の溝部２５が形成されている。そして、奥側の取付側面部２６（図４（ａ）中、上側の側面）には、ネジ止め用のネジ孔２７、２７が形成されている。また、取付側面部２６に対向する側面部２８（図４（ａ）中、下側の側面）の前側の部分（図４（ｂ）中、左側の部分）は、ほぼ直角に折り曲げられて（図４（ａ）中、下側方向に折り曲げ）上記ヒンジ軸支持部材１２Ａと摺接する摺接部２９が形成されている。そして、この摺接部２９のほぼ中央位置には、前記回動支軸１６の軸径よりも少し大きい径の軸孔１７が形成されている。また、この軸孔１７から摺動部２９の前側（図４（ａ）中、左側）端縁部の方向に向かうと共に、該前側端縁部に向かって上側（図４（ｂ）中、上側）に傾斜する断面略三角形状の案内溝部３１が形成されている。また、この案内溝部３１の前端面（図４（ｂ）中、左端面）の溝深さ寸法は、前記回動支軸１６の高さ寸法とほぼ等しく形成されている。また、この案内溝部３１の頂点部分と軸孔１７とは、前記回動支軸１６の軸径寸法よりも少し小さい幅寸法を有する切欠き溝３２が形成されている。さらに、案内溝部３１の溝幅は、軸孔１７側の溝幅よりも前側端縁部の溝幅の方が広く形成されている。また、この案内溝部３１と切欠き溝３２により軸誘導部が構成されている。
そして、前記ヒンジ軸受部１２Ｂは、前側端面（図４（ａ）中、左端面）が内枠２の左側端面と同じ位置になると共に、取付側面部２６が内枠２の裏側になるように、溝部２５が内枠２の左上角部上端面に嵌め込まれ、内枠２の裏側からネジ止め等により取り付けられる（図２参照）。
【００２２】
次に、ヒンジ軸受部材１２Ｂのヒンジ軸支持部材１２Ａへの組み付けについて図５に基づいて説明する。図５は第１実施形態に係る内枠取付用ヒンジ１２のヒンジ軸支持部材１２Ａとヒンジ軸受部材１２Ｂとの組み付けを示す図である。
図５に示すように、下ヒンジ１１の下固定部材１１Ａに下回動部材１１Ｂを組み付けたときに、ヒンジ軸受部材１２Ｂの摺接部２９の下面は、ヒンジ軸支持部材１２Ａの軸取付部２３の上面とほぼ同じ高さになるように内枠２の左上角部上端面に取り付けられている。よって、ヒンジ軸受部材１２Ｂの案内溝部３１を矢印３５の方向、即ち回動支軸１６の方向に押し込むと、ヒンジ軸受部１２Ｂの案内溝部３１は、二点鎖線で示されるように、ヒンジ軸支持部材１２Ａの回動支軸１６に当接しつつ、回動支軸１６のテーパー面１６Ａに沿って持ち上げられて、前側（図５中、左側）に移動する。そして、回動支軸１６が案内溝部３１の頂点部付近に近づくと、該回動支軸１６の先端部が切欠き溝３２に入り、目視により回動支軸１６と案内溝部３１及び切欠き溝３２との位置合わせが確認される。さらに、ヒンジ軸受部材１２Ｂを矢印３５の方向に押し込むと、該回動支軸１６のテーパー面１６Ａが軸孔１７の周縁部に当接し、内枠２の自重により、軸孔１７がテーパー面１６Ａに沿って、回動支軸１６にはめ入れられ、摺接部２９の下面が軸取付部２３に当接される。
【００２３】
以上詳細に説明した通り、第１実施形態の内枠取付用ヒンジ１２においては、内枠２を後傾させつつ、下ヒンジ１１の下固定部材１１Ａに下回動部材１１Ｂを組み付け後、内枠２を外枠４の前面側に開いた状態に位置させて、外枠４の左上角部の方向に押し込むことにより、ヒンジ軸支持部材１２Ａの回動支軸１６が、ヒンジ軸受部材１２Ｂの案内溝部３１に当接される。さらに、ヒンジ軸受部材１２Ｂを矢印３５（図５参照）の方向に押し込むことにより、回動支軸１６の先端部が切欠き溝３２に入り、軸孔１７の周縁部まで案内され、内枠２の自重により、軸孔１７がテーパー面１６Ａに沿って、回動支軸１６にはめ入れられ、摺接部２９の下面が軸取付部２３の上面に当接される。これにより、ヒンジ軸支持部材１２Ａとヒンジ軸受部材１２Ｂとにより内枠取付用ヒンジ１２が構成される。
【００２４】
したがって、回動支軸１６が横方向から案内溝部３１及び切欠き溝３２に摺接しつつ軸孔１７に案内されて、この軸孔１７にはめ入れられるため、横方向から極めて容易に内枠２を外枠４に取り付けることが可能となる。また、この回動支軸１６の軸孔１７から横方向への外れを防止するためのロック部材等が必要ないため、機械的故障や内枠２の不意の落下等のおそれを無くすことが可能となると共に、ロック部材等の部品点数の削減が可能となるため、製造コストの削減を図ることが可能となる。さらに、前記回動支軸１６は軸孔１７に挿入されるため、内枠２をこの回動支軸１６の軸方向に着脱可能となるため、製造ラインの組み付け用装置による内枠２の取り付けができるため、製造ラインにおける作業性や生産性の向上を図ることが可能となる。
また、案内溝部３１は、前記軸孔１７の周辺部からヒンジ軸受部材１２Ｂの前端縁部の方向に向かうと共に、該端縁部に向かって上側に傾斜する断面略三角形状に形成されているため、横方向からこの案内溝部３１の前端縁部を容易に回動支軸１６の先端に当接することが可能となり、横方向から内枠２を取り付ける作業を容易に行うことが可能となる。
また、案内溝部３１は、該案内溝部３１の前端縁部側の溝幅が軸孔１７側の溝幅よりも広くなるように形成されているため、前記回動支軸１６をこの案内溝部３１に対して正確に位置決めをすることなく、容易に軸孔１７方向へ案内することが可能となり、組み付け作業の作業性向上を図ることが可能となる。
さらに、回動支軸１６を案内溝部３１から軸孔１７に案内する該回動支軸１６の軸径よりも狭い溝幅の切欠き溝３２が形成され、内枠２の取り付け時に、この回動支軸１６の先端部に形成されるテーパー面等が切欠き溝３２を摺接して軸孔１７に挿入される目視確認できるため、確実に内枠２を横方向から取り付けることが可能となると共に、作業不良を無くすることが可能となる。
【００２５】
次に、第２実施形態に係る内枠取付用ヒンジについて図６に基づいて説明する。図６は第２実施形態に係る内枠取付用ヒンジのヒンジ軸受部材を示す図で、（ａ）は平面図、（ｂ）は側面図である。
第２実施形態に係るパチンコ機及び内枠取付用ヒンジの概略構成は第１実施形態のパチンコ機１及び内枠取付用ヒンジ１２の構成とほぼ同じ構成である（図１乃至図４参照）が、図６に示すように、ヒンジ軸受部材３８の摺接部２９のほぼ中央位置には、前記回動支軸１６の軸径よりも少し大きい径の軸孔１７が形成され、この軸孔１７から摺動部２９の前側（図６（ａ）中、左側）端縁部の方向に向かうと共に、該前側端縁部に向かって上側（図６（ｂ）中、上側）に傾斜する断面略三角形状の案内溝部３９が形成されている。また、この案内溝部３９の前端面（図６（ｂ）中、左端面）の溝深さ寸法は、前記回動支軸１６の高さ寸法とほぼ等しく形成されている。また、この案内溝部３９の前側端縁部の近傍位置から軸孔１７まで前記回動支軸１６の軸径寸法よりも少し小さい幅寸法を有する切欠き溝４０が形成されている。さらに、案内溝部３９の溝幅は、軸孔１７側の溝幅よりも前側端縁部の溝幅の方が広く形成されている。また、この案内溝部３９と切欠き溝４０により軸誘導部が構成されている。
そして、このヒンジ軸受部３８は、前側端面（図６（ａ）中、左端面）が内枠２の左側端面と同じ位置になると共に、取付側面部２６が内枠２の裏側になるように、溝部２５が内枠２の左上角部上端面に嵌め込まれ、内枠２の裏側からネジ止め等により取り付けられる（図２参照）。
【００２６】
以上説明した通り、第２実施形態の内枠取付用ヒンジにおいては、内枠２を後傾させつつ、下ヒンジ１１の下固定部材１１Ａに下回動部材１１Ｂを組み付け後、内枠２を外枠４の前面側に開いた状態に位置させて、外枠４の左上角部の方向に押し込むことにより、ヒンジ軸支持部材１２Ａの回動支軸１６が、ヒンジ軸受部材３８の案内溝部３９に当接される。さらに、ヒンジ軸受部材１２Ｂを矢印３５（図５参照）の方向に押し込むことにより、回動支軸１６の先端部が切欠き溝４０に入り、軸孔１７の周縁部まで案内され、内枠２の自重により、軸孔１７がテーパー面１６Ａに沿って、回動支軸１６にはめ入れられ、摺接部２９の下面が軸取付部２３の上面に当接される。これにより、ヒンジ軸支持部材１２Ａとヒンジ軸受部材３８とにより内枠取付用ヒンジが構成される。
【００２７】
したがって、回動支軸１６が横方向から案内溝部３９及び切欠き溝部４０に摺接しつつ軸孔１７に案内されて、この軸孔１７に挿入されるため、横方向から極めて容易に内枠２を外枠４に取り付けることが可能となる。また、この回動支軸１６の軸孔１７から横方向への外れを防止するためのロック部材等が必要ないため、機械的故障や内枠２の不意の落下等のおそれを無くすことが可能となると共に、ロック部材等の部品点数の削減が可能となるため、製造コストの削減を図ることが可能となる。さらに、前記回動支軸１６は軸孔１７に挿入されるため、内枠２をこの回動支軸１６の軸方向に着脱可能となるため、製造ラインの組み付け用装置による内枠２の取り付けができるため、製造ラインにおける作業性や生産性の向上を図ることが可能となる。
また、案内溝部３９は、前記軸孔１７からヒンジ軸受部材３８の前端縁部の方向に向かうと共に、該端縁部に向かって上側に傾斜する断面略三角形状に形成されているため、横方向からこの案内溝部３９の前端縁部を容易に回動支軸１６の先端に当接することが可能となり、横方向から内枠２を取り付ける作業を容易に行うことが可能となる。
また、案内溝部３９は、該案内溝部３９の前端縁部側の溝幅が軸孔１７側の溝幅よりも広くなるように形成されているため、前記回動支軸１６をこの案内溝部３９に対して正確に位置決めをすることなく、容易に軸孔１７方向へ案内することが可能となり、組み付け作業の作業性向上を図ることが可能となる。
さらに、回動支軸１６を案内溝部３９の前端縁の近傍位置から軸孔１７に案内する該回動支軸１６の軸径よりも狭い溝幅の切欠き溝４０が形成され、内枠２取り付け時に、この回動支軸１６の先端部が案内溝部３９に接触すると、直ちに切欠き溝４０にはまるため、回動支軸がこの切欠き溝４０を摺接して軸孔１７にはまるのを目視確認でき、より確実に内枠２を外枠４の横方向から取り付けることが可能となると共に、作業不良を無くすることが可能となる。
【００２８】
次に、第３実施形態に係る内枠取付用ヒンジについて図７に基づいて説明する。図７は第３実施形態に係る内枠取付用ヒンジの組み付けを示す要部の拡大平面図である。
第３実施形態に係るパチンコ機の概略構成は第１実施形態のパチンコ機１の構成とほぼ同じ構成である（図１参照）。また、図７に示すように、第１実施形態に係る内枠取付用ヒンジ１２に代えて第３実施形態に係る内枠取付用ヒンジ４２が取り付けられている。この内枠取付用ヒンジ４２は、外枠４の左上角部にネジ止め等により固定されるヒンジ軸受部材４５と、内枠２の左上角部にネジ止め等により固定されるヒンジ軸支持部材５５とから構成される。
【００２９】
先ず、外枠４の左上角部にネジ止め等により固定されるヒンジ軸受部材４５について説明する。図７に示すように、ヒンジ軸受部材４５は、略Ｌ字形に折り曲げられた金属製の部材であって、外枠４の厚さ寸法とほぼ同じ幅寸法の各折曲部４６、４６には、各々ネジ止め用の皿孔４７が２箇所ずつ形成されている。そして、外枠４の左側端面に当接する折曲部４６（図７中、上側の折り曲げ部４６）は、外枠４の前面側に延出されると共に、上部が略Ｌ字形に内側（図７中、下方向）へ折り曲げられて、摺接部４８が形成されている。そして、この摺接部４８の前半分（図７中、左側半分）のほぼ中央位置には、後述の回動支軸５８の軸径よりも少し大きい径の軸孔４９が形成されている。また、この軸孔４９から摺動部４８の斜め右内側（図７中、斜め左下側）の端縁部の方向に向かうと共に、該端縁部に向かって下側（図７中、紙面裏側方向）に傾斜する断面略三角形状の案内溝部５０が形成されている。また、この案内溝部５０の前端面（図７中、左下端面）の溝深さ寸法は、後述の回動支軸５８の高さ寸法とほぼ等しく形成されている。また、この案内溝部５０の頂点部分と軸孔４９とは、後述の回動支軸５８の軸径寸法よりも少し小さい幅寸法を有する切欠き溝５１が形成されている。さらに、案内溝部５０の溝幅は、軸孔４９側の溝幅よりも前側端縁部の溝幅の方が広く形成されている。また、この案内溝部５０と切欠き溝５１により軸誘導部が構成されている。

続いて、内枠２の左上角部にネジ止め等により固定されるヒンジ軸支持部材５５について説明する。図７に示すように、ヒンジ軸支持部材５５は、略Ｌ字形に折り曲げられた金属製の部材であって、一方の折曲部は、内枠２の左上角部の上端面（図７中、上端部）に載置され、他方の折り曲げ部は、取付側面部５６として内枠２の裏側（図７中、右側面）に当接される。そして、この取付側面部５６には、ネジ止め用のネジ孔５９、５９が形成され、ヒンジ軸支持部材５５は、内枠２の裏面からネジ止め等により固定される。また、前記一方の折り曲げ部の内枠２の左側端面側の一部分が、内枠２の前面側（図７中、左側）に延出されると共に、内側端面部（図７中、下側）が略Ｌ字形に下側（図７中、紙面裏側）へ折り曲げられて、軸取付部５７が形成されている。そして、この軸取付部５７の左側（図７中、上側）端縁部下面に回動支軸５８がカシメ等によりほぼ垂直（図７中、紙面に垂直）に固定されている。また、この回動支軸５８の先端部にはテーパー面が形成されている。
【００３１】
次に、外枠４への内枠２の組み付け、即ち、ヒンジ軸受部材４５へのヒンジ軸支持部材５５の組み付けについて説明する。先ず、下ヒンジ１１の下固定部材１１Ａに下回動部材１１Ｂを組み付けたときに、ヒンジ軸支持部材５５の軸取付部５７の下面は、ヒンジ軸受部材４５の摺接部４８の上面とほぼ同じ高さになるように内枠２の左角部上面に取り付けられている。よって、内枠２を外枠４に対して所定の角度（第３実施形態では、約３０度）開いた状態で、前記回動支軸５８の先端を前記案内溝部５０の前端部に押し当てて、内枠２を矢印６１の方向に押し込むことにより、回動支軸５８の先端部が案内溝部５０の底面部に当接しつつ、案内溝部５０の底面部に沿って持ち上げられて、軸孔４９方向に移動する。そして、回動支軸５８が案内溝部５０の頂点部付近に近づくと、該回動支軸５８の先端部に形成されるテーパー面が切欠き溝５１に入り、目視により回動支軸５８と案内溝部５０及び切欠き溝５１との位置合わせが確認される。さらに、内枠２を、即ち、ヒンジ軸支持部材５５を矢印６１の方向に押し込むと、該回動支軸５８の先端部のテーパー面が軸孔１７の周縁部に当接し、内枠２の自重により、該回動支軸５８が軸孔４９に挿通されて、軸取付部５７の下面が摺接部４８の上面に当接される。
【００３２】
以上詳細に説明した通り、第３実施形態の内枠取付用ヒンジ４２においては、内枠２を後傾させつつ、下ヒンジ１１の下固定部材１１Ａに下回動部材１１Ｂを組み付け後、内枠２を外枠４に対して所定の角度（第３実施形態では、約３０度）開いた状態で、前記回動支軸５８の先端を前記案内溝部５０の前端部に押し当てて、内枠２を押し込むことにより、回動支軸５８が案内溝部５０及び切欠き溝５１を摺接して、軸孔４９に挿通され、軸取付部５７の下面が摺接部４８の上面に当接される。これにより、ヒンジ軸受部材４５とヒンジ軸支持部材５５とにより内枠取付用ヒンジ４２が構成される。
【００３３】
したがって、回動支軸５８が横方向から案内溝部５０及び切欠き溝５１に摺接しつつ軸孔４９に案内されて、この軸孔４９に挿入されるため、斜め横方向から極めて容易に内枠２を外枠４に取り付けることが可能となる。また、この回動支軸５８の軸孔４９から横方向への外れを防止するためのロック部材等が必要ないため、機械的故障や内枠２の不意の落下等のおそれを無くすことが可能となると共に、ロック部材等の部品点数の削減が可能となるため、製造コストの削減を図ることが可能となる。さらに、前記回動支軸５８は軸孔４９に挿入されるため、内枠２をこの回動支軸５８の軸方向に着脱可能となるため、製造ラインの組み付け用装置による内枠２の取り付けができるため、製造ラインにおける作業性や生産性の向上を図ることが可能となる。
また、案内溝部５０は、前記軸孔４９の周辺部から摺接部４８の内側の斜め前端の方向に向かうと共に、該斜め前端に向かって下側に傾斜する断面略三角形状に形成されているため、斜め横方向からこの案内溝部５０の前端縁部に回動支軸５８の先端を容易に当接することが可能となり、斜め横方向から内枠２を取り付ける作業を容易に行うことが可能となる。
また、案内溝部５０は、該案内溝部５０の前端縁部側の溝幅が軸孔４９側の溝幅よりも広くなるように形成されているため、前記回動支軸５８をこの案内溝部５０に対して正確に位置決めをすることなく、容易に軸孔４９の方向へ案内することが可能となり、組み付け作業の作業性向上を図ることが可能となる。
さらに、回動支軸５８を案内溝部５０から軸孔４９に案内する該回動支軸５８の軸径よりも狭い溝幅の切欠き溝５１が形成されているため、内枠２取り付け時に、この回動支軸５８の先端部に形成されるテーパー面が、切欠き溝５１を摺接して軸孔４９に挿入されるの目視確認できるため、確実に内枠２を斜め横方向から取り付けることが可能となると共に、作業不良を無くすることが可能となる。
【００３４】
尚、本発明は前記第１乃至第３の実施形態に限定されるものではなく、本発明の要旨を逸脱しない範囲内で種々の改良、変形が可能であることは勿論である。
【００３５】
【発明の効果】
以上説明した通り本発明は、ヒンジ軸支持部材に鉛直方向に立設される回動支軸を設け、ヒンジ軸受部材に軸孔と軸誘導部とを設けることにより、回動支軸が横方向から軸誘導部に当接されつつ軸孔に案内されて、この軸孔に挿入されるため、回動支軸の横方向への外れ防止用弾性部材やロック部材等を無くすことが可能となると共に、回動支軸が軸孔に挿入されるため、内枠の該回動支軸の軸方向の着脱が可能な内枠取付用ヒンジを提供することができる。

FIG. 5 is a view showing the assembly of the hinge shaft support member 12A and the hinge bearing member 12B of the inner frame mounting hinge 12 according to the first embodiment.
 As shown in FIG. 5, when the lower rotating member 11B is assembled to the lower fixing member 11A of the lower hinge 11, the lower surface of the sliding contact portion 29 of the hinge bearing member 12B is the shaft mounting portion 23 of the hinge shaft support member 12A. It is attached to the upper left corner of the upper left corner of the inner frame 2 so as to be almost the same height as the upper surface of the inner frame 2. Therefore, when the guide groove portion 31 of the hinge bearing member 12B is pushed in the direction of the arrow 35, that is, the direction of the rotation support shaft 16, the guide groove portion 31 of the hinge bearing portion 12B supports the hinge shaft as shown by the two-dot chain line. While being in contact with the rotating support shaft 16 of the member 12A, it is lifted along the tapered surface 16A of the rotating support shaft 16 and moved to the front side (left side in FIG. 5). When the pivot shaft 16 approaches the vicinity of the apex of the guide groove portion 31, the tip end portion of the pivot shaft 16 enters the notch groove 32, and the pivot shaft 16, the guide groove portion 31, and the notch are visually observed. The alignment with the groove 32 is confirmed. Further, when the hinge bearing member 12B is pushed in the direction of the arrow 35, the tapered surface 16A of the rotating support shaft 16 comes into contact with the peripheral portion of the shaft hole 17, and the shaft hole 17 is tapered 16A by the own weight of the inner frame 2.

It abuts on the groove 31. Furthermore, by pushing the hinge bearing member 12B in the direction of the arrow 35 (see FIG. 5), the tip end portion of the rotation support shaft 16 enters the notch groove 32 and is guided to the peripheral edge portion of the shaft hole 17, and the inner frame 2 Due to its own weight, the shaft hole 17 is fitted into the rotation support shaft 16 along the tapered surface 16 A, and the lower surface of the sliding contact portion 29 is brought into contact with the upper surface of the shaft mounting portion 23. Accordingly, the hinge 12 for the inner frame is configured by the hinge shaft support member 12A and the hinge bearing member 12B.
[0024]
 Therefore, since the rotation support shaft 16 is guided to the shaft hole 17 while being in sliding contact with the guide groove portion 31 and the notch groove 32 from the lateral direction and is fitted into the shaft hole 17, the inner frame 2 can be very easily viewed from the lateral direction. Can be attached to the outer frame 4. Further, since there is no need for a locking member or the like for preventing the pivot shaft 16 from coming off from the shaft hole 17 in the lateral direction, it is possible to eliminate the possibility of mechanical failure or unexpected drop of the inner frame 2. At the same time, the number of parts such as a lock member can be reduced, so that the manufacturing cost can be reduced. Further, since the rotation support shaft 16 is inserted into the shaft hole 17, the inner frame 2 can be attached and detached in the axial direction of the rotation support shaft 16.
