Description

【０００１】
【発明の属する技術分野】
本発明は、遊技機の施解錠装置に関し、特に、前枠を外枠に開閉可能に支持したパチンコ遊技機、パチスロ遊技機等の遊技機において、前枠が閉じられたときにその前枠を外枠に係止するために用いられる遊技機の施解錠装置に関する。
【０００２】
【従来の技術】
従来より、パチンコ遊技機等の遊技機には、前枠を外枠に対し施錠するための施解錠装置が組み込まれている。施解錠装置としては、枠体、上下一対の鉤部材、連結杆、シリンダ錠およびカム板を備えたものがよく知られている。枠体は前枠に取り付けられ、両鉤部材は枠体の上下両端部に軸により支持されている。各鉤部材は軸を支点として傾動することにより、外枠に固定された受け金具に対し係止および離脱する。連結杆は枠体に上下方向への往復動可能に配置され、その連結杆の上下両端部が前記鉤部材に連結されている。シリンダ錠は枠体に組み込まれており、解錠に際し鍵が差し込まれて回転操作される。
【０００３】
カム板はシリンダ錠の錠軸に取り付けられており、鍵の操作にともなう錠軸の回転を連結杆に伝達して、同連結杆を下方へ移動させる。上記遊技機の施解錠装置によると、施錠時には、連結杆が上方に位置していて両鉤部材が受け金具に係止している。鍵が所定方向に回されると、錠軸の回転がカム板を介して連結杆に伝わる。連結杆の下方への移動により、上下両鉤部材が同時に傾動してそれぞれ受け金具から離脱、解錠される。このように、遊技機の施解錠装置は、鍵をシリンダ錠に差し込んで回した場合に解錠される構造に設計されている。
【０００４】
【発明が解決しようとする課題】
パチンコホールのシマにおいては、多数台のパチンコ遊技機が横に列をなして並べられ、さらに隣り合うパチンコ遊技機の間には玉貸し機が配置される。この玉貸し機の設置のために通常は、隣り合うパチンコ遊技機が玉貸し機の幅よりも多少広めの間隔で配置される。これにともない、パチンコ遊技機と玉貸し機との間に若干の隙間が生じる。ここで、上述した従来の施解錠装置における鉤部材は、鉤部分全体が外側に露出している。従って、針金等の線材を上記隙間を通じて差し込み、この露出している鉤部分に直接力を加えることによって、鉤部材を傾動させることが可能であるといった問題があった。
【０００６】
本発明は、上記課題にかんがみてなされたもので、枢止ピンによる鉤部材と施錠杆の係止および施錠杆に形成した移動孔の形状に基づいて、鉤部材を単独で傾動させた場合に、単独で傾動動作可能とし、施錠杆が上方に移動した場合、すなわち、解錠操作がなされた場合には鉤部材が連動して傾動して受け金具からスムーズに離脱可能とする施解錠装置の提供を目的とする。
【０００７】
【課題を解決するための手段】
上記目的を達成するため、請求項１にかかる発明は、遊技機の前枠に配設され、鍵により施解錠操作される施解錠手段と、上記施解錠操作に応じて上下動可能に構成された施錠杆と、上記遊技機の外枠に備えられた被係止部に対して係止する係止部を有し、上記係止部が係止および離脱するように回動可能に枢支された鉤部材と、上記被係止部に対して上記係止部が係止される方向に回動するように上記鉤部材を付勢する付勢手段と、第１部分と第２部分とを有する移動孔に挿入され、上記施錠杆と上記鉤部材を移動可能に係止する枢支ピンとを具備し、上記鉤部材は、上記鍵による解錠操作によって上記施錠杆が移動する場合には、上記枢支ピンが上記第１部分を移動することにより上記施錠杆の上下動と連動して上記被係止部に対して上記係止部が離脱する方向に回動し、上記施錠杆が施錠位置にある状態において傾動させた場合には、上記枢支ピンが上記第２部分を移動することにより上記被係止部に対して上記係止部が離脱する方向に回動可能に構成されている構成としてある。
【０００９】
なお、本発明は上記構成に限られるものではなく、以下の手段を含むものである。
手段１
上記係止手段は、上記係止部が略板形状に形成されるとともに、上記被係止部に係止する部位に係止爪が形成され、同係止爪にて同被係止部に係止される構成としてもよい。
上記のように構成した発明においては、相対面する双方の係止部を略板形状に形成する。そして、略板形状に係止爪を形成し、この係止爪にて外枠の被係止部を相互に係止する。
【００１０】
手段２
係止手段に形成された係止爪の形状の一例として、上記係止手段は、上記係止爪から上記略板形状の幅方向であるとともに、同係止爪が形成された反対側の先端に向かう傾斜形状が形成されている構成としてもよい。
上記のように構成した発明においては、前枠と外枠とを施錠する場合、前枠は外枠に対して進入して閉じられる。一方、前枠と外枠とを解錠した場合、前枠は外枠から退避して開けられる。すなわち、施錠時において前枠に配設された係止部は、先端部分から外枠に配設された被係止部に進入しつつ同被係止部に係止することになる。このとき、係止爪から係止部の幅方向であって、係止爪が形成された反対側に向かう傾斜形状を形成しておく。これにより、被係止部に進入する際に、傾斜形状を被係止部に向けて進入させることができ、傾斜形状を被係止部に当接させつつ相対面する係止部をこの傾斜形状に沿って広げつつ、傾斜形状の終了ポイントにて係止爪を被係止部に係止させる。
【００１１】
手段３
このとき、上記係止手段は、上記傾斜形状が急峻に形成されている構成としてもよい。
上記のように構成した発明においては、傾斜形状が急峻であるため、係止部に針金等の線材が引き掛け難くすることができる。傾斜形状を急峻に形成する際の傾斜角度は、係止部に対して針金等の線材を引き掛け難くすることが可能であれば良く、特に限定されない。例えば、相対面する係止部を重ね合わせたときに、二つの傾斜形状によって外側に形成する角度が鈍角になるように傾斜形状を形成すれば、傾斜形状を急峻にすることができる。
【００１２】
手段４
上述したように前枠を外枠に対して閉じる場合、前枠は外枠に対して進入する。そして、このとき係止部が被係止部に対して進入する。このとき、係止部を被係止部により進入させ易くすることができる形状の一例として、上記外枠に配設された被係止部は、上記係止部の傾斜形状に対面する側に頂角を向けた断面略三角形状に形成されている構成としてもよい。
上記のように構成した発明においては、係止部が被係止部に進入する際、係止部を断面略三角形状の傾斜部分にて導きつつ進入させる。
【００１３】
手段５
相対面する係止部が鍵による施解錠動作においては相互に連動して係止、離脱動作を行い、鍵に依らない一方の係止部に対する操作においては単独で動作するようにすると好適である。そこで、上記係止手段は、何れか一方の係止部に対する上記被係止部からの離脱操作が行なわれた場合に、他方の係止部の同被係止部からの離脱を遮断する離脱遮断手段を有している構成としてもよい。
上記のように構成した発明においては、離脱遮断手段によって、一方の係止部について被係止部からの離脱操作を行ったとしても、他方の係止部を被係止部に係止させたままにする。
【００１４】
手段６
上記係止部に対して線材等をより引き掛け難くすることができる構成の一例として、上記係止手段は、上記係止部の重なり合う面が略面一に形成されている構成してもよい。
上記のように構成した発明においては、係止部が重なり合う面を略面一に形成することによって、線材等が引き掛かり得る部分を排除する。
【００１５】
【発明の効果】
以上説明したように本発明によれば、枢止ピンによる鉤部材と施錠杆の係止および施錠杆に形成した移動孔の形状に基づいて、鉤部材を単独で傾動させた場合に、単独で傾動動作可能とし、施錠杆が上方に移動した場合、すなわち、解錠操作がなされた場合には鉤部材が連動して傾動して受け金具からスムーズに離脱可能とする施解錠装置を提供することができる。
【００１６】
【発明の実施の形態】
ここでは、下記の順序に従って本発明の実施形態について説明する。なお、本発明は、以下の態様によって限定されるものではない。
（１）遊技機の構成：
（２）施解錠装置の構成：
（３）まとめ：
【００１７】
（１）遊技機の構成：
図１および図２は、本発明にかかる施解錠装置が適用される遊技機の一実施形態であるパチンコ遊技機の前面図および内部透視側面図である。
図において、パチンコ遊技機１は、外枠２と、軸１ａにより外枠２に開閉可能に支持された前枠（内枠と呼ばれることもある）３と、前枠３に組付けられた遊技盤４と、軸１ａにより前枠３に開閉可能に支持されたガラス枠５とを備えている。外枠２内の右側部には被係止部が固定されている。被係止部は、剛性の高い材料、例えば金属板によって形成されている。ここでは、被係止部として、金属板を断面略三角形状に曲げ形成したもの（以下「受け金具」という）が用いられ、これが木ねじ等によって外枠２に固定されている。受け金具の数は複数（２つ以上）であり、ここでは２個の受け金具（第１受け金具６および第２受け金具７）が用いられている。第１受け金具６は、外枠２の下部に固定され、第２受け金具７は、外枠２の上部に固定されている。
【００１８】
また、前枠３の裏面の右側部には、縦長の施解錠装置８が組付けられている。この施解錠装置８には、係止爪を有する第１鉤部材８ａと、第２鉤部材８ｂと、第３鉤部材８ｃと、第４鉤部材８ｄとが備えられている。かかる場合、第１鉤部材８ａと、第２鉤部材８ｂとが第１受け金具６に対して上下に相対面して配設されるとともに、第２鉤部材８ｃと、第３鉤部材８ｄととが第２受け金具７に対して上下に相対面した配設される。そして、前枠３が閉じられたときに、第１鉤部材８ａおよび第２鉤部材８ｂが第１受け金具６に係止し、第３鉤部材８ｃおよび第４鉤部材８ｄが第２受け金具７に係止する。また、本実施形態においては、第１鉤部材８ａおよび第２鉤部材８ｂが第１受け金具６に係止した際、第３鉤部材８ｃおよび第４鉤部材８ｄが第２受け金具７に係止した際に、係止爪の一部が重なり合うように配設されている。このように、施解錠装置８は前枠３を外枠２に係止するための機構を備えている。また、この施解錠装置８は他の機構としてと、ガラス枠５が閉じられたときにそのガラス枠５を前枠３に係止するための機構を備えている。本実施形態においては、主として前者の機構について説明し、後者の機構については説明を省略する。
【００１９】
（２）施解錠装置の構成：
図３は上述した施解錠装置８の正面図であり、図４は同左側面図、図５は同右側面図、図６は同背面図、図７は同施解錠装置８の部分拡大分解斜視図を示している。図において、施解錠装置８には、施錠杆９が前枠３の内側において、前枠３の支持板１１に沿って施錠位置と解錠位置との間で摺動可能に配設されている。前枠３は、所定形状の金属製の板材を折り曲げて形成したものであって、縦長の取付板１２の長手方向の一側縁（図６における右側縁）に上方の支持板１３、中間の支持板１４、下方の支持板１５に分割された支持板１１が取付板１２に対し垂直に起立して形成されており、取付板１２の長手方向の他側縁（図６における左側縁）から、上端から下端にわたり直線状で細幅の補強片１６が取付板１２に支持板１１と同一側に垂直に起立して形成されている。
【００２０】
取付板１２は、上方部と下方部が同一幅で、中間部が幅方向に拡張された幅広部１２ａとなっている。従って、上方の支持板１３、中間の支持板１４、下方の支持板１５は互いに平行であり、また、これら支持板１３，１４，１５と補強片１６とは平行となっている。取付板１２には、施解錠装置８をパチンコ遊技機１の本体枠の裏面に取り付けることができるように止めネジ挿通孔８１が穿設されている。中間の支持板１４に対応する取付板１２の幅広部１２ａには、錠取付け孔１７が穿設され、この錠取付け孔１７にシリンダ錠１８を挿通し、フランジ部１９のネジ孔（図示せず）と、取付板１２のネジ孔２０、２０との位置を合わせた状態においてネジ２１、２１で螺着されている。シリンダ錠１８の錠軸（図示せず）には、施錠杆９を施錠位置から解錠位置に移動させたり、作動杆２２を非作動位置から作動位置に移動させるためのカム板２３が取り付けられている。
【００２１】
また、取付板１２は中間の支持板１４と下方の支持板１５の間において取付板１２の幅方向（外側）に張り出された張り出し部２４が形成されている。この張り出し部２４には、パチンコ遊技機１のリセットに使用される光電スイッチ等の非接触スイッチ２５がネジ止めされている。支持板１１には、抜け止め頭部２６ａに連接した首部２６ｂを有する略Ｔ字状の打ち抜き起立片２６が形成され、起立片２６は首部の基端部において折り曲げ加工されて支持板１１から前枠３の内側（図６においては支持板の左側面側）に向けて突設されている。施錠杆９は、支持板１１の縦方向の長さより若干短い金属製の板材からなり、上方の支持板１３、中間の支持板１４、下方の支持板１５に沿って移動ができるように中間部が中間の支持板１４側に折り曲げられて所定長さの段部２７が形成されている。
【００２２】
施錠杆９には、起立片２６に応じ、その抜け止め頭部２６ａの挿通を可能とする挿通部２８ａと抜け止め首部２６ｂで案内される案内部２８ｂからなる略Ｔ字状の案内孔２８が穿設されている。案内孔の挿通部２８ａに起立片の抜け止め頭部２６ａを挿通できるように支持板１１に施錠杆９を合わせ、挿通部２８ａに抜け止め頭部２６ａを挿通させた後、案内部２８ｂが起立片２６の抜け止め首部２６ｂで案内されて施錠杆９が移動するように設定することで、施錠杆９は抜け止め頭部２６ａにより抜け、浮き上がりが防止されて、抜け止め首部２６ｂに案内部２８ｂが案内されて上下方向に移動することができることとなる。下方の支持板１５の下部には、その後縁１５ａ寄りの位置において、係止爪８ａ１を上方に向けた第１鉤部材８ａおよび係止爪８ｂ１を下方に向けた第２鉤部材８ｂが、枢支ピン２９〜３２により傾動可能に枢支されている。
【００２３】
第１鉤部材８ａおよび第２鉤部材８ｂは、係止爪８ａ１および係止爪８ｂ１から先端に向かう傾斜辺が形成されている。上方の支持板１３の上部には、その後縁１３ａ寄りの位置において、係止爪８ｃ１を下方に向けた第３鉤部材８ｃおよび係止爪８ｄ１を上方に向けた第４鉤部材８ｄが、枢支ピン３３〜３６により傾動可能に枢支されている。第３鉤部材８ｃおよび第４鉤部材８ｄは、係止爪８ｃ１および係止爪８ｄ１から先端に向かう傾斜辺が形成されている。従って、施錠杆９を上方に摺動させると、第１鉤部材８ａは枢止ピン２９を中心にして図８において下方に傾動し、第２鉤部材８ｂは枢止ピン３２を中心にして上方に傾動する。この傾動については詳細を後述する。
【００２４】
また、施錠杆９を上方に摺動させると、第３鉤部材８ｃは枢止ピン３４を中心にして図８において上方に傾動し、第４鉤部材８ｄは枢止ピン３５を中心にして下方に傾動する。施錠杆９の段部２７を形成するための折り曲げ深さは、施錠杆９と中間の支持板１４、および施錠杆９と下方の支持板１５の間に、作動杆２２が挿入される挿入スペースが形成されるように設定されている。そして、該挿入スペースに作動杆２２が挿入され、非作動位置と作動位置とに移動可能とされる。上方の支持板１３の長手方向の後縁１３ａにはストッパー片３７が形成されており、施錠杆９の上方の後縁９ａには、このストッパー片３７を受け入れる切欠３８が形成されている。
【００２５】
ストッパー片３７は、前枠３の内側に向けて支持板１１に直角に折り曲げられて、切欠３８に受け入れられ、ストッパー片３７の上端が切欠３８の上辺と当接した施錠位置と、ストッパー片３７の下端が切欠３８の下辺と当接した解錠位置において、施錠杆９は停止するようになっており、その間で移動可能とされている。ここにおいて、ストッパー片３７が折り曲げられて、施錠杆９の切欠３８に受け入れられた後は、ストッパー片３７の上端が切欠３８の上辺と当接した施錠位置においては、案内部２８ｂの上辺が起立片２６の近傍に位置しており、ストッパー片３７の下端が切欠３８の下辺と当接した解錠位置においては、起立片２６が案内孔２８の挿通部２８ａにまでは達せず、案内部２８ｂに位置するようにストッパー片３７と切欠３８、起立片２６と案内部２８ｂとが設定されており、施錠杆９が施錠位置から解錠位置まで移動しても、施錠杆９の案内孔の挿通部２８ａに起立片２６が位置することがなく、施錠杆９が起立片２６から外れるようなことがない。
【００２６】
施錠杆９の上方部にはバネ掛止爪３９が設けられており、該バネ掛止爪３９に引張バネ４０の一端が掛止され、他端が取付板１２に設けられたバネ掛止爪４１に掛止され、施錠杆９が下方に付勢されるようになっている。従って、引張バネ４０の付勢力により施錠杆９は、施錠杆９の切欠３８の上辺がストッパー片３７の上端に当接した施錠位置において常時は停止している。施錠杆９の下方部には、作動杆２２に設けられたバネ掛止片４２の移動を可能とする縦長の逃がし孔４３が形成されている。施錠杆９の段部２７には、カム板２３の第１突部２３ａに係合する係合孔４４が穿設されており、シリンダ錠１８の作動によりカム板２３を図６における反時計方向（以後カム板の回動方向については、図６に基づくものとして説明する。）に回動させると、カム板２３の第１突部２３ａが係合孔４４の上辺に係合し、施錠杆９が引張バネ４０の付勢力に抗し、施錠位置から解錠位置にまで上方に向けて移動できるようになっている。
【００２７】
作動杆２２は、金属製の板材を段状に折り曲げてなり、上部には、中間の支持板１４に設けられた起立片２６の抜け止め頭部２６ａの挿通を可能とする挿通部と首部２６ｂで案内される案内部を備えた略Ｔ字状の案内孔部４５ａとカム板２３の第１突部２３ａの通過を可能とする逃がし孔部４５ｂとが連結されたクランク状の複合孔４５が穿設されている。作動杆２２は複合孔４５の案内孔部４５ａの下辺が起立片２６の首部２６ｂに当接する非作動位置と、案内孔部４５ａの上辺が起立片２６の首部２６ｂに当接する作動位置とで、作動杆２２が停止し、その間で作動杆２２の移動が可能とされている。作動杆２２の後縁２２ａの中間部には、外側に非接触スイッチ２５を作動させるための遮光片４６が折り曲げ形成されており、下部には、バネ掛止片４２が内側に折り曲げ形成されている。
【００２８】
このバネ掛止片４２は、施錠杆９の逃がし孔４３を通って前枠３の内側に突出しており、バネ掛止片４２の先端に引張バネ４７の一端が掛止され、他端が支持板１３に設けられたバネ掛止爪４８に掛止され、作動杆２２が上方に付勢されるようになっている。従って、引張バネ４７の付勢力により作動杆２２は、複合孔４５の案内孔部４５ａの下辺が中間の支持板１４に設けられた起立片２６の首部２６ｂに当接する非作動位置において常時は停止している。施錠杆９の段部２７には、カム板２３の第２突部２３ｂを通過させるための逃がし孔４９が穿設されており、シリンダ錠１８を作動させカム板２３を時計方向へ回動させる時に第２突部２３ｂが通過し、第２突部２３ｂが作動杆２２の上辺２２ｂに当接し、作動杆２２を引張バネ４７の付勢力に抗し下方に移動させる。
【００２９】
そして、中間の支持板１４には、カム板２３の反時計方向への回動時に第１突部２３ａを通過させ、また、カム板２３の時計方向への回動時に第２突部２３ｂを通過させるための逃がし孔５０が穿設されている。また、上方の支持板１３の後縁、中間の支持板１４の後縁、下方の支持板１５の後縁には内側に向かって適宜長さの折り曲げ片５１が形成されている。このような構造の施解錠装置８は、図８に示すように、その支持板１３の表面をパチンコ遊技機１の前枠３の裏面に当て、支持板１３の止めネジ挿通孔８１を利用して、ネジで取り付けて使用する。外枠２には、施解錠装置８の第１鉤部材８ａおよび第２鉤部材８ｂに対応した位置に下方の受け金具６が、第３鉤部材８ｃおよび第４鉤部材８ｄに対応した位置に上方の受け金具７が設けられている。
【００３０】
前枠３を施錠するには、蝶番を支点として前枠３を回動させると、先ず、外枠２に取り付けられた下方の受け金具６の傾斜下辺に第１鉤部材８ａの傾斜辺が、下方の受け金具６の傾斜上辺に第２鉤部材８ｂの傾斜辺が、上方の受け金具７の傾斜上辺に第３鉤部材８ｃの傾斜辺が、上方の受け金具７の傾斜下辺に第４鉤部材８ｄの傾斜辺が当接し、第１鉤部材８ａは枢止ピン２９を中心にして下方に傾動し、第２鉤部材８ｂは枢止ピン３２を中心に上方に傾動する。また、第３鉤部材８ｃは枢止ピン３４を中心にして上方に傾動し、第４鉤部材８ｄは枢止ピン３５を中心にして下方に傾動する。
【００３１】
さらに、前枠３を回動させると、下方の受け金具６の傾斜下辺を第１鉤部材８ａの係止爪８ａ１が、下方の受け金具６の傾斜上辺を第２鉤部材８ｂの係止爪８ｂ１が、上方の受け金具７の傾斜上辺を第３鉤部材８ｃの係止爪８ｃ１が、上方の受け金具７の傾斜下辺を第４鉤部材８ｄの係止爪８ｄ１が受け金具６，７を乗り越えると、下方の受け金具６に第１鉤部材の係止爪８ａ１と第２鉤部材８ｂの係止爪８ｂ１が、上方の受け金具７に第３鉤部材８ｃの係止爪８ｃ１と第４鉤部材８ｄの係止爪８ｄ１が係合し、前枠３が閉鎖され外枠２に施錠されることになる。
【００３２】
前枠３を解錠するには、シリンダ錠１８にキーを差し込みカム板２３を時計方向に操作する。すると、カム板２３の第１突部２３ａが係合孔４４に係合し、引張バネ４０の付勢力に抗し、施錠杆９が上方の解錠位置にまで移動する。この施錠杆９の上方への移動に伴い、第１鉤部材８ａ〜第４鉤部材８ｄがそれぞれ上方あるいは下方に傾動し、第１鉤部材８ａの係止爪８ａ１と第２鉤部材８ｂの係止爪８ｂ１との間、および、第３鉤部材８ｃの係止爪８ｃ１と第４鉤部材８ｄの係止爪８ｄ１との間がそれぞれ下方の受け金具６および上方の受け金具７との係合がはずれるだけの間隔に達し、解錠され、前枠３が蝶番を支点として施錠時と逆方向に回動させ前枠３を開放する。シリンダ錠１８にキーを差し込みカム板２３を反時計方向に操作すると、カム板２３の第２突部２３ｂが逃がし孔４９を通過して作動杆２２の上辺２２ｂに当接し、作動杆２２が引張バネ４７の付勢力に抗し下方に移動される。
【００３３】
これにより作動杆２２は、複合孔４５の案内孔部４５ａの下辺が起立片２６の首部２６ｂに当接する非作動位置から案内孔部４５ａの上辺が起立片２６の首部２６ｂに当接する作動位置にまで移動し、作動杆２２の遮光片４６によって非接触スイッチ２５が作動し、リセットが行われる。シリンダ錠１８の作動を解除することで、作動杆２２は引張バネ４７の付勢力により非作動位置にまで戻される。
【００３４】
次に、受け金具６，７に対して係止および離脱させる機構の各構成について説明する。本実施形態においては、施解錠装置８の下方に取り付けられた第１鉤部材８ａおよび第２鉤部材８ｂの機構について説明する。当該施解錠装置８の上方に取り付けられた第３鉤部材８ｃおよび第４鉤部材８ｄの機能は同様であることは言うまでもない。図９は、第１鉤部材８ａの外観を示した外観図である。図１０は、第２鉤部材８ｂの外観を示した外観図である。図１１は、施錠杆９の下端部の概略構成図である。図１２は、支持板１５の下端部の概略構成図である。図において、第１鉤部材８ａは、略長方形の板形状に形成され、右端部（先端部）に係止爪８ａ１が形成されるとともに、この係止爪８ａ１から下方に向けて傾斜を有する傾斜部８ａ２が形成されている。
【００３５】
また、左端部（後端部）には枢止ピン２９を挿入するピン挿入孔８ａ３と、枢止ピン３０を挿入するピン挿入孔８ａ４が形成されている。さらに、この後端部の下方隅部には、この第１鉤部材８ａを下方に付勢する引張バネを引き掛けるバネ取付部８ａ５が外側に向けて立設されている。同様に、第２鉤部材８ｂは、略長方形の板形状に形成され、右端部（先端部）に係止爪８ｂ１が形成されるとともに、この係止爪８ｂ１から上方に向けて傾斜を有する傾斜部８ｂ２が形成されている。また、左端部（後端部）には枢止ピン３１を挿入するピン挿入孔８ｂ３と、枢止ピン３２を挿入するピン挿入孔８ｂ４が形成されている。
【００３６】
さらに、この後端部の上方隅部には、この第２鉤部材８ｂを下方に付勢する引張バネを引き掛けるバネ取付部８ｂ５が外側に向けて立設されている。施錠杆９の下端部には、枢止ピン２９が挿入され、第１鉤部材８ａの傾動に伴って枢止ピン２９が移動するための移動孔９１が形成されるとともに、枢止ピン３０が挿入され、同第１鉤部材８ａの傾動に伴って枢止ピン３０が移動するための移動孔９２が形成されている。ここで、移動孔９１は、横幅方向に形成された逃げ孔９１ａと、略円弧形状に形成された円弧孔９１ｂとから構成されている。一方、移動孔９２は、上下方向に長い略長方形形状に形成されている。
【００３７】
そして、この移動孔９１，９２の上部には、枢止ピン３１が挿入され、第２鉤部材８ｂの傾動に伴って枢止ピン３１が移動するための移動孔９３が形成されるとともに、枢止ピン３２が挿入され、同第２鉤部材８ｂの傾動に伴って枢止ピン３２が移動するための移動孔９４が形成されている。ここで、移動孔９３は、上下方向に長い略長方形形状に形成されている。一方、移動孔９４は、横幅方向に形成された逃げ孔９４ａと、略円弧形状に形成された円弧孔９４ｂとから構成されている。支持板１５の下端部には枢止ピン３０を挿入するためのピン挿入孔１５１と、枢止ピン３１を挿入するためのピン挿入孔１５２が形成されるとともに、第１鉤部材８ａのバネ取付部８ａ５に引き掛けた引張バネの他方端を引き掛けるバネ取付部１５３と、第２鉤部材８ｂのバネ取付部８ｂ５に引き掛けた引張バネの他方端を引き掛けるバネ取付部１５４とが形成されている。
【００３８】
上記構成において、第１鉤部材８ａと第２鉤部材８ｂとを施錠杆９および支持板１５に枢止ピン２９〜３２を使用して組み付けた時の構成を図１３に示す。同図においては、枢止ピン２９を第１鉤部材８ａのピン挿入孔８ａ３および施錠杆９の移動孔９１に挿入するとともに、同第１鉤部材８ａと施錠杆９をこの枢止ピン２９によって係止する。また、枢止ピン３０を第１鉤部材８ａのピン挿入孔８ａ４、施錠杆９の移動孔９２および支持板１５のピン挿入孔１５１に挿入するとともに、同第１鉤部材８ａと施錠杆９と支持板１５とをこの枢止ピン３０によって係止する。次に、枢止ピン３２を第２鉤部材８ｂのピン挿入孔８ｂ４および施錠杆９の移動孔９４に挿入するとともに、同第２鉤部材８ｂと施錠杆９をこの枢止ピン３２によって係止する。
【００３９】
そして、枢止ピン３１を第２鉤部材８ｂのピン挿入孔８ｂ３、施錠杆９の移動孔９３および支持板１５のピン挿入孔１５２に挿入するとともに、同第２鉤部材８ｂと施錠杆９と支持板１５とをこの枢止ピン３１によって係止する。そして、バネ取付部８ａ５，１５３に引張バネＳ１を取り付けるとともに、バネ取付部８ｂ５，１５４に引張バネＳ２を取り付ける。ここで、本実施形態においては、第１鉤部材８ａと第２鉤部材８ｂは受け金具６に係止した場合、領域Ｒをもって重なり合わさるように配設する。従って、この領域Ｒの部分においては、第１鉤部材８ａは断面が折れ曲がって形成されており、この折れ曲がり部分に第２鉤部材８ｂの領域Ｒに該当する部分が嵌め合わされるようになり、第１鉤部材８ａおよび第２鉤部材８ｂの外側面は面一に形成されることになる。
【００４０】
また、上述したように枢止ピン２９〜３２による第１鉤部材８ａ、第２鉤部材８ｂ、施錠杆９、支持板１５の係止および施錠杆９に形成した各移動孔９１〜９４の形状に基づいて、本実施形態においては、各第１〜４鉤部材８ａ〜８ｄを単独で傾動させた場合に他の鉤部材に何等影響を与えることがなく、単独で傾動動作可能とし、施錠杆９が上方に移動した場合、すなわち、シリンダ錠１８にて解錠操作がなされた場合に各第１〜４鉤部材８ａ〜８ｄが連動して傾動して受け金具６，７から離脱可能にする機能を実現可能としている。本実施形態においては、鉤部材８ａ，８ｂの先端に形成する傾斜部８ａ２，８ｂ２を垂直方向に急峻になるように形成した。これにより、針金等の線材を第１鉤部材８ａおよび第２鉤部材８ｂに引き掛けにくくすることが可能になり好適である。この急峻の度合いは、特定の度合いに限定されるものではないが、図１７に示すように第１鉤部材８ａと第２鉤部材８ｂとを重なり合わせた場合に、傾斜部８ａ２，８ｂ２の外側にて形成される角度αが鈍角（９０°＜α＜１８０°）を形成するようにすると急峻な傾斜形状を形成できて好適である。
一方、上述した実施形態においては、第１鉤部材８ａの傾斜部８ａ２および第２鉤部材８ｂの傾斜部８ｂ２の傾斜角度が被係止部６の傾斜面の傾斜角度より大きく形成されている。このように傾斜角度を被係止部６の傾斜面の傾斜角度より大きく形成した場合、第１鉤部材８ａおよび第２鉤部材８ｂが被係止部６に向かって進入するとき、傾斜部８ａ２，８ｂ２と被係止部６は略点接触して進入方向に移動する。ここで、この移動をスムーズに実施させると言う観点においては、図１８に示すように、第１鉤部材８ａ，第２鉤部材８ｂの傾斜部８ａ２,８ｂ２の傾斜角度を被係止部６の傾斜面の傾斜角度と略一致させると良い。これによって、移動時に相互の傾斜を略線接触させながら動かすことが可能となり、被係止部６に対する第１鉤部材８ａおよび第２鉤部材８ｂの移動をスムーズに実施することが可能になる。
【００４１】
図１４は、第１鉤部材８ａを単独で傾動させた場合の構成を示した構成図である。同図において、第１鉤部材８ａを下方に傾動させると、枢止ピン３０を回転軸にして同第１鉤部材８ａは回動する。このとき、枢止ピン２９は、移動孔９１の円弧孔９１ｂに沿って上方に移動する。このように、第１鉤部材８ａは単独で傾動動作するため、針金等の線材をこの第１鉤部材８ａに引き掛けて受け金具６から離脱させても、第２鉤部材８ｂは受け金具６に係止したままなので、解錠することができない。図１５は、第２鉤部材８ｂを単独で傾動させた場合の構成を示した構成図である。同図において、第２鉤部材８ｂを上方に傾動させると、枢止ピン３１を回転軸にして同第２鉤部材８ｂは回動する。このとき、枢止ピン３２は、移動孔９４の円弧孔９４ｂに沿って上方に移動する。上述したのと同様に、第２鉤部材８ｂは単独で傾動動作するため、針金等の線材をこの第２鉤部材８ｂに引き掛けて受け金具６から離脱させても、第１鉤部材８ａは受け金具６に係止したままなので、解錠することができない。
【００４２】
一方、施錠杆９が上方に動いた場合、すなわち、シリンダ錠１８にて解錠操作がなされた場合は、第１鉤部材８ａと第２鉤部材８ｂとを連動して傾動させて、受け金具６から離脱させる必要がある。かかる場合の構成を図１６の構成図に示す。同図において、施錠杆９がシリンダ錠１８における解錠操作に伴って上方に移動すると、第１鉤部材８ａは、枢止ピン２９を回転軸にして回動する。このとき、枢止ピン２９は、回動に伴って、逃げ孔９１ａにおいて横方向に移動する。一方、枢止ピン３０は移動孔９２において相対的に下方に移動する。また、第２鉤部材８ｂは、枢止ピン３２を回転軸にして回動する。このとき、枢止ピン３２は、回動に伴って、逃げ孔９４ａにおいて横方向に移動する。一方、枢止ピン３２は移動孔９３において相対的に下方に移動する。このように施錠杆９の上方への移動においては、第１鉤部材８ａおよび第２鉤部材８ｂを連動して傾動させることによって、受け金具６から離脱させ解錠することが可能になる。
【００４３】
（３）まとめ：
このように、第１鉤部材８ａおよび第２鉤部材８ｂを受け金具６に係止させた際に、係止爪８ａ１および係止爪８ｂ１の一部が重なり合うように、当該第１鉤部材８ａおよび第２鉤部材８ｂを配設することによって、第１鉤部材８ａおよび第２鉤部材８ｂに針金等の線材を差し込み難くすることができ、不正行為を防止することが可能になる。
