Description

【０００１】
【発明の属する技術分野】
この発明は、腕時計などの指針式時計に関する。
【０００２】
【従来の技術】
従来、指針式の腕時計においては、腕時計ケース内の上部に見切り部材を配置した状態で時計ガラスを装着することにより、見切り部材を腕時計ケース内に固定し、時計モジュールの上面に文字板を配置して時計モジュールの外周面を緩衝ゴムで覆い、この状態で時計モジュールを緩衝ゴムと共に腕時計ケース内にその下面側から収納した後、腕時計ケースの下部に裏蓋を締め込んで螺着することにより、裏蓋の内面に設けられた緩衝体を介して時計モジュールを腕時計ケース内に固定した耐衝撃構造のものがある。
この場合、時計モジュールには、時針や分針などの指針が文字板の上方に位置した状態で運針するように設けられており、文字板の周縁部には、１時〜１２時に対応して時字が一体に設けられている。また、見切り部材には、文字板の時字に対応して分目盛などの見切りマークが印刷により設けられている。
【０００３】
【発明が解決しようとする課題】
しかしながら、このような腕時計では、時計モジュールに設けられた文字板と見切り部材とが腕時計ケース内に別々に固定されている構造であるから、時計モジュールを組み込むときに、文字板の時字と見切り部材の見切りマークとがずれてしまうという問題がある。特に、裏蓋を回しながら腕時計ケースの下部に締め込んで螺着するときに、裏蓋の回転に伴って時計モジュールも多少回転するため、文字板の時字と見切り部材の見切りマークとがずれてしまう。また、時計モジュールの外周面が緩衝ゴムで覆われた状態で腕時計ケース内に装着されているため、落下などの衝撃を受けた際に、時計モジュールが腕時計ケース内で僅かに動き、これによっても、文字板の時字と見切り部材の見切りマークとがずれてしまう。
なお、このような問題を回避する手法として、文字板の時字と見切り部材の見切りマークとがずれても、そのずれが目立たないように、例えば、見切り部材の見切りマークを目盛線や目盛ドットなどの形状で印刷した場合、文字板の時字をアラビア数字などで現わすことが考えられている。しかし、このような手法においても、文字板の時字と見切り部材の見切りマークとのずれを防ぐことはできない。
【０００４】
この発明の課題は、見切り部材と時字との位置ずれを防ぐことである。
また、この発明の他の課題は、見切り部材、時字、および時計モジュールの相互の位置ずれを防ぐことである。
【０００５】
【課題を解決するための手段】
この発明は、上記課題を解決するために、次のような構成を備えている。なお、各構成要素には、後述する各実施形態の項で説明される各要素に付されている図面の参照番号などを括弧とともに付す。
すなわち、請求項１記載の発明は、図６〜図９に示すように、時計ケース（腕時計ケース１）と、この時計ケース内に収納され、指針を有する時計モジュール（６）と、この時計モジュール上に設けられ、前記指針が上方で運針する文字板（１０）と、
この文字板の周縁部上に配置され、平板状のリング（１３）の内周面に時字部（１４）が複数の時字に対応して前記リングの内側に突出して設けられ、且つ外周面に突起部（３２）が設けられた時字パネル（１１）と、
前記時計モジュールの外周部に装着して前記時字パネルの下側に配置され、且つ外周面に突起部（３１）が前記時字パネルにおける前記突起部に対応して設けられた中枠（１７）と、
前記時字パネルおよび前記時計モジュールが前記中枠と共に収納され、且つ前記時字パネルにおける前記突起部と前記中枠における前記突起部とが挿入して前記時字パネルと前記中枠とを位置決めするための切欠部（３３）が設けられた内装部材（１８）と、
この内装部材により前記時計ケースに対し固定され、前記時字パネルにおける前記時字部がそれぞれ嵌合して前記時字パネルを位置決めする位置決め凹部（１６）が複数設けられた見切り部材（３０）とを備えていることを特徴とする指針式時計である。
この発明によれば、文字板と時字パネルとを別々に構成し、この時字パネルを文字板の周縁部上に配置して見切り部材によって位置決めしたので、見切り部材と時字パネルとの位置ずれを防ぐことができるほか、時計モジュールが装着する中枠の外周部と時字パネルの外周部に設けられた突起部をそれぞれ内装部材の切欠部に係合させたので、時計モジュールを組み込む際、あるいは落下などの衝撃を受けた際に、時計モジュール、中枠、時字パネル、および内装部材が一体的に動くことになり、このため時計モジュールと時字とが位置ずれすることがなく、これにより見切り部材、時字、および時計モジュールの相互の位置ずれを確実に防ぐことができる。
【０００７】
【発明の実施の形態】
［第１実施形態］
以下、図１〜図５を参照して、この発明を指針式腕時計に適用した第１実施形態について説明する。
図１は指針式腕時計の外観正面図であり、図２はその要部の拡大断面図である。
この指針式腕時計は、腕時計ケース１を備えている。この腕時計ケース１内の上部には、図２に示すように、その内面に形成された鍔部２上に見切り部材３が配置された状態で時計ガラス４がパッキン５を介して装着され、この時計ガラス４により見切り部材３が鍔部２に押し付けられて固定されている。また、この腕時計ケース１内には、時計モジュール６が収納されており、腕時計ケース１の下面には、裏蓋７がパッキン８を介して締め込みにより螺着されている。なお、腕時計ケース１の上面には、時計ガラス４の周囲に沿って取付溝１ａが設けられており、この取付溝１ａには、ベゼル９がパッキン９ａを介して時計ガラス４の周縁部上を覆った状態で取り付けられている。
【０００８】
時計モジュール６は、時計機能に必要な電子回路およびアナログムーブメントを備え、その上面に文字板１０が設けられ、アナログムーブメントの指針軸が文字板１０の上方に突出し、その先端部に図１に示すように時針、分針、秒針などの指針６ａが運針可能に取り付けられた構成になっている。この場合、文字板１０は、その表面に模様やマークをデザイン的に表現した平板であり、従来の時字は設けられていない構造になっている。
この文字板１０の周縁部上には、時字パネル１１がスペーサ１２を介して配置されている。時字パネル１１は、図３に示すように、平板状のリング１３の内周面に１時〜１２時に対応する時字部１４が内側に向けて突出形成され、各時字部１４の先端面上に時字１４ａが蛍光塗料などの印刷によって設けられた構成になっている。この場合、各時字部１４のうち、１２時に位置する時字部１４は幅広に形成されており、これ以外はすべて同じ幅で形成されている。また、スペーサ１２は、滑り易い材質からなる合成樹脂製のシートであり、時字パネル１１のリング部１３の下面に対応して配置されている。
【０００９】
一方、前述した時字パネルを面方向に位置決めするための位置決め部材である見切り部材３は、図４（ａ）および図４（ｂ）に示すように、全体がリング状に形成されたものであり、腕時計ケース１内の鍔部２上に配置される平坦部３ａと、この平坦部３ａから腕時計ケース１の内側に向けて斜め下方に傾斜する傾斜部３ｂとが一体に形成されている。この場合、傾斜部３ｂの表面には、図５に示すように、分目盛などの見切りマーク１５が印刷により設けられている。また、傾斜部３ｂの下端部には、時字パネル１１の各時字１４ａを露出させた状態で、時字パネル１１の各時字部１４の付け根部分のみがそれぞれ嵌合して時字パネル１１を位置決めする位置決め部としての凹部１６が１時〜１２時の位置に対応して形成されている。これら位置決め部としての凹部１６のうち、１２時と６時に対応する位置決め部としての凹部１６は、図５（ａ）〜図５（ｃ）に示すように、時字パネル１１の１２時と６時に位置する各時字部１４の幅とほぼ同じ大きさで、公差がきわめて小さく形成されており、他の位置決め部としての凹部１６は各時字部１４の幅よりも広く形成されている。これにより、時字パネル１１は、１２時と６時に対応する位置決め部としての凹部１６によって時字パネル１１の面方向が位置決めされ、図５（ａ）および図５（ｂ）に示すように、各時字部１４の時字１４ａが見切り部材３の見切りマーク１５と一致するようになっている。
【００１０】
ところで、時計モジュール６は、図２に示すように、その外周部に中枠１７が装着され、上面に設けられた文字板１０上に時字パネル１１を配置した状態で、金属からなる円筒状の内装部材１８内に収納されている。この内装部材１８は、その外周部に装着された緩衝ゴム１９によって覆われた状態で、腕時計ケース１内に装着されている。この場合、内装部材１８の上端部には、時字パネル１１のリング部１３の上面に当接する鍔部１８ａが設けられており、緩衝ゴム１９の上端部には、内装部材１８の鍔部１８ａの上面に当接し、かつ腕時計ケース１内の鍔部２の下面に当接する鍔部１９ａが設けられている。
一方、裏蓋７は、その内面に装着突起部２０がリング状に形成され、この装着突起部２０の外周面に形成された雄ねじ２１が腕時計ケース１の内周面に形成された雌ねじ２２に螺着することにより、腕時計ケース１の下部に締め込まれて取り付けられている。この裏蓋７の内面には、金属製の滑り板２３が配置されており、この滑り板２３上には、時計モジュール６の下面に弾接する円板状の緩衝ゴム２４、および中枠１７の下面に弾接するリング状の緩衝ゴム２５が配置されている。なお、裏蓋７の外周縁には、緩衝用のゴムリング２６が装着されている。
【００１１】
次に、このような指針式腕時計を組み立てる場合について説明する。
まず、腕時計ケース１の上方より見切り部材３を腕時計ケース１内に挿入して鍔部２上に見切り部材３の平坦部３ａを配置する。この後、腕時計ケース１内の上部にパッキン５を介して時計ガラス４を装着し、この時計ガラス４により見切り部材３の平坦部３ａを鍔部２に押し付けて固定する。そして、腕時計ケース１の上面に設けられた取付溝１ａにパッキン９ａを介してベゼル９を装着し、このベゼル９で時計ガラス４の周縁部上を覆い隠す。
一方、時計モジュール６においては、その外周部に中枠１７を装着し、時計モジュール６の上面に文字板１０を固定した上、この文字板１０の上方に突出したアナログムーブメントの指針軸に指針６ａを運針可能に取り付ける。そして、文字板１０の周縁部上にスペーサ１２を介して時字パネル１１を配置する。この状態で、時字パネル１１および時計モジュール６を中枠１７と共に内装部材１８内に収納し、この内装部材１８の鍔部１８ａに時字パネル１１のリング部１３の上面を当接させる。この後、内装部材１８の外周面に緩衝ゴム１９を装着し、この緩衝ゴム１９の鍔部１９ａに内装部材１８の鍔部１８ａの上面を当接させる。
【００１２】
この状態で、時字パネル１１、時計モジュール６、および中枠１７が収納された内装部材１８を緩衝ゴム１９と共に腕時計ケース１内にその下側から収納し、時字パネル１１の各時字１４ａを露出させた状態で、時字パネル１１の各時字部１４の付け根部分のみを見切り部材３の傾斜部３ｂの下端部に形成された各位置決め部としての凹部１６にそれぞれ嵌合させる。このときには、図５（ａ）〜図５（ｃ）に示すように、１２時と６時に対応する位置決め部としての凹部１６と、これに対応する１２時と６時の時字部１４との公差が小さいので、見切り部材３の各位置決め部としての凹部１６により時字パネル１１の面方向を精度良く位置決めすることができ、これにより、図５（ａ）および図５（ｂ）に示すように、各時字部１４の時字１４ａと見切り部材３の見切りマーク１５とを正確に一致させることができる。
【００１３】
この後、裏蓋７の内面に滑り板２３を介して円板状の緩衝ゴム２４およびリング状の緩衝ゴム２５を配置し、この裏蓋７の装着突起部２０の雄ねじ２１を腕時計ケース１の内面の雌ねじ２２に締め込んで螺着する。これにより、円板状の緩衝ゴム２４が時計モジュール６を弾力的に押し上げるとともに、リング状の緩衝ゴム２５が中枠１７を弾力的に押し上げる。このため、時字パネル１１のリング部１３、内装部材１８の鍔部１８ａ、および緩衝ゴム１９の鍔部１９ａが腕時計ケース１内の鍔部２に押し付けられて固定される。このとき、緩衝ゴム２４、２５が時計モジュール６および中枠１７を押え付けた状態で、裏蓋７が回転しても、滑り板２３により時計モジュール６および中枠１７は裏蓋７と共にほとんど回転することはない。しかし、仮に裏蓋７と共に時計モジュール６、中枠１７、および文字板１０が多少回転したとしても、見切り部材３により時字パネル１１が位置決めされているので、時字部１４の時字１４ａと見切り部材３の見切りマーク１５とが位置ずれすることはない。
【００１４】
このように、この指針式腕時計では、時計モジュール６に設けられた文字板１０と時字パネル１１とを別々に構成し、この時字パネル１１を文字板１０の周縁部上に配置して見切り部材３によって位置決めしたので、見切り部材３と時字パネル１１とが別々の部品であっても、時計モジュール６を組み込む際、あるいは落下などの衝撃を受けた際に、見切り部材３に対して時字パネル１１が位置ずれすることがなく、見切り部材３と時字パネル１１との位置ずれを確実に防ぐことができる。
また、この指針式腕時計では、文字板１０の周縁部上に合成樹脂製のスペーサ１２を介して時字パネル１１を配置したので、時計モジュール６を組み込む際、あるいは落下などの衝撃を受けた際に、時計モジュール６と共に文字板１０が腕時計ケース１内で動いたとしても、時字パネル１１によって文字板１０にすり傷を付けないようにすることができ、しかも文字板１０の周縁部上に時字パネル１１を配置したことにより、時字構造として立体感のあるものを得ることができる。
更に、この指針式腕時計では、時字パネル１１上に突出して形成された複数の時字部１４と位置決め部材３に形成された複数の位置決め部１６とが互いに嵌合しているので、時計モジュール６を組み込む際、あるいは落下などの衝撃を受けた際に、位置決め部材３に対して時字パネル１１が位置ずれすることがなく、位置決め部材３と時字パネル１１との位置ずれを確実に防ぐことができる。
【００１５】
［第２実施形態］
次に、図６〜図９を参照して、この発明を指針式腕時計に適用した第２実施形態について説明する。なお、図１〜図５に示された第１実施形態と同一部分には同一符号を付し、その説明は省略する。
この指針式腕時計は、図６に示すように、見切り部材３０の形状および設置位置が第１実施形態と異なるとともに、内装部材１８に対する時字パネル１１と中枠１７の取付構造も異なり、これら以外は第１実施形態と同じ構成になっている。
すなわち、見切り部材３０は、図６に示すように、腕時計ケース１の下方から挿入されて腕時計ケース１内の鍔部２の下面に配置されている。この見切り部材３０は、全体がリング状に形成されたものであり、鍔部２の下面に配置される平坦部３０ａと、この平坦部３０ａの内端部にその上下に突出して斜めに傾斜した傾斜部３０ｂとが一体に形成されている。この場合にも、傾斜部３０ｂの表面には、第１実施形態と同様、分目盛などの見切りマーク１５が印刷により設けられている。また、傾斜部３０ｂの下端部には、時字パネル１１の各時字１４ａを露出させた状態で、時字パネル１１の各時字部１４の付け根部分のみがそれぞれ嵌合して時字パネル１１を位置決めする位置決め部としての凹部１６が１時〜１２時の位置に対応して形成されている。
【００１６】
また、時計モジュール６の外周部に装着した中枠１７の外周面には、図８および図９に示すように、突起部３１が設けられており、文字板１０上に配置された時字パネル１１のリング部１３の外周面には、図７および図８に示すように、突起部３２が中枠１７の突起部３１に対応して設けられている。
一方、時計モジュール６、中枠１７、文字板１０、および時字パネル１１が装着する内装部材１８には、図８および図９に示すように、中枠１７の突起部３１および時字パネル１１の突起部３２が挿入して係合する逆Ｕ字状の切欠部（係合部）３３が下端部に開放されて設けられている。また、この内装部材１８の外周に装着する緩衝ゴム１９にも、逆Ｕ字状の切欠部３４が内装部材１８の切欠部３３に対応して設けられている。
【００１７】
このような指針式腕時計を組み立てる場合には、まず、腕時計ケース１の上部にパッキン５を介して時計ガラス４を装着した後、腕時計ケース１の上面に設けられた取付溝１ａにパッキン９ａを介してベゼル９を装着し、このベゼル９により時計ガラス４の周縁部上を覆い隠す。
一方、時計モジュール６においては、図９に示すように、その外周部に中枠１７を装着し、時計モジュール６の上面に文字板１０を固定して、その上方に突出した指針軸に指針６ａを取り付けた後、文字板１０の周縁部上にスペーサ１２を介して時字パネル１１を配置し、この時字パネル１１の突起部３２と中枠１７の突起部３１とを対応させる。
【００１８】
この状態で、時計モジュール６、中枠１７、文字板１０、および時字パネル１１を内装部材１８内にその下側から挿入して装着する。このときには、時字パネル１１の突起部３２と中枠１７の突起部３１とを内装部材１８の切欠部３３に対応させてその下側より順に挿入して係合させる。この後、内装部材１８の外周面に緩衝ゴム１９を装着する。このときにも、内装部材１８の切欠部３３に緩衝ゴム１９の切欠部３４を対応させ、この切欠部３４内に時字パネル１１および中枠１７の各突起部３２、３１を若干突出させて挿入させる。
そして、緩衝ゴム１９の鍔部１９ａ上に見切り部材３０の平坦部３０ａを配置するとともに、この見切り部材３０の下端部の各位置決め部としての凹部１６に時字パネル１１の各時字部１４の付け根部分のみをそれぞれ嵌合させて位置決めし、各時字部１４の時字１４ａと見切り部材３の見切りマーク１５とを一致させる。
【００１９】
この状態で、時字パネル１１、時計モジュール６、および中枠１７が収納された内装部材１８および緩衝ゴム１９を見切り部材３０と共に腕時計ケース１内に収納し、見切り部材３０の平坦部３０ａを腕時計ケース１内の鍔部２の下面に当接させる。
この後、第１実施形態と同様に、裏蓋７の装着突起部２０に形成された雄ねじ２１を腕時計ケース１の内面に形成された雌ねじ２２に締め込んで螺着し、円板状の緩衝ゴム２４で時計モジュール６を押し上げるとともに、リング状の緩衝ゴム２５で中枠１７を押し上げ、これにより時字パネル１１のリング部１３、内装部材１８の鍔部１８ａ、緩衝ゴム１９の鍔部１９ａ、および見切り部材３０の平坦部３０ａを腕時計ケース１内の鍔部２に押し付けて固定する。
【００２０】
このときには、緩衝ゴム２４、２５が時計モジュール６および中枠１７を押え付けた状態で、裏蓋７が回転しても、第１実施形態と同様、滑り板２３により時計モジュール６および中枠１７は裏蓋７と共にほとんど回転することはない。しかし、仮に裏蓋７と共に時計モジュール６および中枠１７が多少回転したときには、中枠１７および時字パネル１１の各外周面にそれぞれ設けられた突起部３１、３２が内装部材１８の切欠部３３内に挿入されて係合しているので、これらが一体的に回転するとともに、時字パネル１１が見切り部材３０によって位置決めされているため、見切り部材３０も一体的に回転することになり、このため見切り部材３０、時字パネル１１、および時計モジュール６の相互の位置ずれを確実に防ぐことができる。このようなことは、組立て時のみに限らず、落下などの衝撃を受けたときも、同様である。
【００２１】
なお、上記第２実施形態では、中枠１７の外周面および時字パネル１１の外周面のそれぞれ１か所に突起部３１、３２を対応させて設け、これらに対応させて内装部材１８の１か所に切欠部３３を設けたが、これに限らず、中枠１７の外周面および時字パネル１１の外周面のそれぞれ複数個所に突起部３１、３２を相互に対応させて設け、これらに対応させて内装部材１８の複数個所に切欠部３３をそれぞれ設けても良い。この場合には、内装部材１８の複数の切欠部３３に対応させて緩衝部材１９の複数個所にも切欠部３４を設ければ良い。
また、上記第１、第２実施形態では、指針式腕時計について述べたが、これに限らず、例えばトラベルウオッチ、目覚まし時計、置き時計などの指針式時計にも広く適用することができる。
【００２２】
【発明の効果】
以上説明したように、請求項１記載の発明によれば、文字板と時字パネルとを別々に構成し、この時字パネルを文字板の周縁部上に配置して見切り部材によって位置決めしたので、見切り部材と時字パネルとの位置ずれを防ぐことができるほか、時計モジュールが装着する中枠の外周部と時字パネルの外周部とに設けられた突起部をそれぞれ内装部材の切欠部に係合させた構成としているので、時計モジュールを組み込む際、あるいは落下などの衝撃を受けた際に、時計モジュール、中枠、時字パネル、および内装部材が一体的に動くことになり、このため時計モジュールと時字とが位置ずれすることがなく、これにより見切り部材、時字、および時計モジュールの相互の位置ずれを確実に防ぐことができる。

BACKGROUND OF THE INVENTION
The present invention relates to a pointer type timepiece such as a wristwatch.
[0002]
[Prior art]
Conventionally, in a wristwatch type wristwatch, the parting member is fixed in the wristwatch case by attaching the watch glass in a state where the parting member is disposed in the upper part of the wristwatch case, and the dial is disposed on the upper surface of the watch module. Cover the outer peripheral surface of the watch module with shock-absorbing rubber, and in this state, store the watch module together with the shock-absorbing rubber from the lower surface side in the watch case, and then tighten the back cover to the lower part of the watch case and screw it. There is an impact-resistant structure in which a timepiece module is fixed in a wristwatch case through a buffer provided on the inner surface of the back cover.
In this case, the timepiece module is provided so that the hands such as the hour hand and the minute hand are moved above the dial, and the peripheral portion of the dial has an hour corresponding to 1 o'clock to 12 o'clock. Characters are provided in one piece. Further, the parting member is provided with a parting mark such as a minute scale by printing corresponding to the time character of the dial.
[0003]
[Problems to be solved by the invention]
However, in such a wristwatch, the dial and the parting member provided on the watch module are separately fixed in the watch case. There is a problem that the parting mark of the member is displaced. In particular, when the back cover is turned and screwed into the lower part of the watch case, the watch module also rotates a little as the back cover rotates, so the time on the dial and the parting mark on the parting member are misaligned. End up. In addition, the watch module is mounted in the watch case with the outer periphery of the watch module covered with shock-absorbing rubber, so that the watch module moves slightly in the watch case when it receives an impact such as dropping. The time character on the dial plate and the parting mark on the parting member are misaligned.
As a technique for avoiding such problems, for example, the parting mark on the parting member should be set to a graduation line or a graduation dot so that the deviation does not stand out even if the time character on the dial and the parting mark on the parting member are misaligned. When printed in a shape such as, it is considered that the time letters on the dial plate appear with Arabic numerals. However, even with such a method, it is not possible to prevent a shift between the time letter on the dial and the parting mark on the parting member.
[0004]
The subject of this invention is preventing the position shift of a parting member and a time character.
Another object of the present invention is to prevent misalignment of the parting member, the time character, and the timepiece module.
