Description

【０００１】
【発明の属する技術分野】
この発明は腕時計バンドに関する。
【０００２】
【従来の技術】
腕時計バンドにおいては、腕時計ケースにバンド本体を連結手段である先カンにより連結する構造のものが知られている。
この種の腕時計バンドは、腕時計ケースおよびバンド本体が金属製または合成樹脂製、あるいはそれらを組み合わせたものなど、種々の材質のものが用いられ、これらの材質に対応させるために、連結手段である先カンとして、金属部材と樹脂部材を組み合わせた構造のものが用いられている。
例えば、腕時計ケースのバンド取付部に装着溝をその先端に沿って形成し、この装着溝に先カンの連結挿入部をスライドさせて装着する構造のものでは、先カンの材料として、ウレタン樹脂などの弾性を有する合成樹脂を用いる必要があるが、先カンが合成樹脂のみで形成されていると、十分な強度が得られないため、金属部材で補強する必要がある。
このような腕時計バンドの先カンとしては、従来、金属部材を樹脂部材に巻き付けて一体化した構造のもの、あるいは金属部材と樹脂部材とを別体に形成してピン部材などで連結した構造のものがある。
【０００３】
【発明が解決しようとする課題】
しかしながら、前者の腕時計バンドでは、連結手段である先カンが金属部材を樹脂部材に巻き付けて一体化した構造であるから、金属部材と樹脂部材の両者が相互に形状の制約を受けことになり、このためデザイン形状に大きな制約が生じるという問題がある。
また、後者の腕時計バンドでは、連結手段である先カンが金属部材と樹脂部材とを単にピン部材で連結した構造であるから、ピン部材を中心に金属部材と樹脂部材とが相対的に回動してしまい、金属部材と樹脂部材との一体感が得られないという問題がある。
【０００４】
この発明の課題は、デザイン的な形状の制約が少なく、金属部材と樹脂部材を別体に形成しても、金属部材と樹脂部材とが一体的な構造のものを得るようにするである。
【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。
請求項１に記載の発明は、図１〜図４または図８〜図１１に示すように、腕時計ケース（２）に連結手段（先カン４または３１）を介してバンド本体（３）が連結される腕時計バンド（１または３０）において、
前記連結手段は、前記バンド本体に連結される金属部材（１４または３２）と、前記腕時計ケースに連結される樹脂部材（１５または３３）と、前記金属部材と前記樹脂部材とを連結する連結部材（１６または３４）とを備え、
前記金属部材には、前記連結部材が係合する金属係合部（１７または３５）と、前記樹脂部材に当接して係止される金属係止部（係止突起部１９または連結押え部３７）とが形成され、
前記樹脂部材には、その一面側から前記金属係合部が嵌合する樹脂嵌合部（樹脂嵌合孔２１または４１）と、前記連結部材が取り付けられる連結取付部（ピン挿入孔２２または４２）と、前記金属係止部が前記樹脂部材の他面側から当接する樹脂係止部（当接凹部２３または４３）とが形成されている
ことを特徴とする。
【０００６】
この発明によれば、金属部材の金属係止部を樹脂部材の樹脂係止部に樹脂部材の前記他面側から当接させるとともに、金属部材の金属係合部を樹脂部材の樹脂嵌合部に樹脂部材の前記一面側から嵌合させ、この状態で樹脂部材の連結取付部に取り付けられた連結部材が金属係合部を係合することにより、金属部材と樹脂部材とを連結させたので、十分な強度を確保でき、これによりバンド全体の薄型化を可能にし、また金属係合部が連結部材により樹脂部材に対して回動可能に連結されていたとしても、金属係止部が樹脂係止部に当接していることにより、金属部材と樹脂部材とが相対的に回動することがないので、その両者を一体的に取り付けることができ、このため金属部材と樹脂部材とを別体に形成したことにより、デザイン的な形状の制約が少なく、しかも金属部材と樹脂部材とを別体に形成しても、金属部材と樹脂部材とが一体的な構造のものを得ることができる。
【０００７】
請求項２に記載の発明は、図１〜図４に示すように、腕時計ケース（２）に連結手段（先カン４）を介してバンド本体（３）が連結される腕時計バンド（１）において、
前記連結手段は、前記バンド本体に連結される金属部材（１４）と、前記腕時計ケースに連結される樹脂部材（１５）と、前記金属部材と前記樹脂部材とを連結するピン部材（１６）とを備え、
前記金属部材における前記腕時計ケース側に位置する端部には、前記ピン部材が係合する金属係合部（１７）が屈曲形成され、前記バンド本体側に位置する前記金属部材の端部には、突起部（係止突起部１９）が前記バンド本体の長手方向と直交する方向に対応する幅方向にそれぞれ突出して形成され、
前記樹脂部材のほぼ中央部分には、その上面側から前記金属係合部が嵌合する樹脂嵌合部（樹脂嵌合孔２１）が形成され、この樹脂嵌合部に対応する箇所における前記樹脂部材には、前記ピン部材が挿入するピン挿入孔（２２）が前記樹脂嵌合部に嵌合された前記金属係合部に対応して形成され、前記バンド本体側に位置する前記樹脂部材の端部には、前記突起部が前記樹脂部材の下面側から当接する当接凹部（２３）がそれぞれ形成されている
ことを特徴とする。
【０００８】
この発明によれば、金属部材の突起部を樹脂部材の当接凹部にその下面側から当接させるとともに、金属部材の金属係合部を樹脂部材の樹脂嵌合部にその上面側から嵌合させ、この状態でピン部材を樹脂部材のピン挿入孔から挿入させて金属係合部に挿入させることにより、金属部材と樹脂部材とを連結させたので、請求項１に記載の発明と同様、十分な強度を確保でき、これによりバンド全体の薄型化を可能にし、また樹脂嵌合部に嵌合された金属係合部がピン部材により樹脂部材に回動可能に連結されていても、金属部材の突起部が樹脂部材の当接凹部に当接していることにより、金属部材と樹脂部材とが相対的に回動することがないので、その両者を一体的に取り付けることができ、このため請求項１に記載の発明と同様の効果があるほか、特に、金属部材に金属係合部を屈曲形成するとともに突起部を幅方向に突出させて形成した構造であるから、金属部材として、金属板を用いてプレス加工により容易に製作することができる。
【０００９】
この場合、請求項３に記載の発明は、図１〜図４に示すように、金属部材（１４）が、バンド本体（３）の長手方向と直交する方向に対応する幅をこれに対応する樹脂部材（１５）の幅よりも短く形成した構造であることにより、腕時計ケース側に位置する金属部材の端部に形成された金属係合部（１７）が樹脂嵌合部（樹脂嵌合孔２１）に上面側から嵌合することにより、バンド本体を上面側から見たとき、金属部材が樹脂部材の幅方向における両側に存在せず、樹脂部材の中間部分に配置された形状のものを得ることができる。
【００１０】
請求項４に記載の発明は、図８〜図１１に示すように、腕時計ケース（２）に連結手段（先カン３１）を介してバンド本体（３）が連結される腕時計バンド（３０）において、
前記連結手段は、前記バンド本体に連結される金属部材（３２）と、前記腕時計ケースに連結される樹脂部材（３３）と、前記金属部材と前記樹脂部材とを連結するピン部材（３４）とを備え、
前記金属部材における前記腕時計ケース側に位置する端部の両側には、前記ピン部材が係合する金属係合部（３５）がそれぞれ屈曲形成され、前記バンド本体側に位置する前記金属部材の端部には、その両側から前記金属係合部側に向けて折り返されて前記端部の両側を連結する連結押え部（３７）が形成され、
前記樹脂部材のほぼ中央部分には、その上面側から前記金属係合部が嵌合する樹脂嵌合部（樹脂嵌合孔４１）がそれぞれ形成され、これら樹脂嵌合部に対応する箇所における前記樹脂部材には、前記ピン部材が挿入するピン挿入孔（４２）が前記樹脂嵌合部に嵌合された前記金属係合部に対応して形成され、前記バンド本体側に位置する前記樹脂部材の端部側には、前記連結押え部が前記樹脂部材の下面側から当接する当接凹部（４３）が形成されている
ことを特徴とする。
【００１１】
この発明によれば、金属部材の連結押え部を樹脂部材の当接凹部にその下面側から当接させるとともに、金属部材の金属係合部を樹脂部材の樹脂嵌合部にその上面側からそれぞれ嵌合させ、この状態でピン部材を樹脂部材のピン挿入孔から挿入させて金属係合部に挿入させることにより、金属部材と樹脂部材とを連結させたので、請求項１に記載の発明と同様、十分な強度を確保でき、これによりバンド全体の薄型化を可能にし、また樹脂部材の樹脂嵌合部に嵌合された金属係合部がピン部材により樹脂部材に回動可能に連結されていても、金属部材の連結押え部が樹脂部材の当接凹部に当接することにより、金属部材と樹脂部材とが相対的に回動することがないので、その両者を一体的に取り付けることができ、このため請求項１に記載の発明と同様の効果があるほか、特に、金属部材に金属係合部をそれぞれ屈曲形成するとともに連結押え部を折り返さして形成した構造であるから、金属部材として、金属板を用いてプレス加工により容易に製作することができる。
【００１２】
この場合、請求５に記載の発明は、図８〜図１１に示すように、金属部材（３２）が、バンド本体（３）の長手方向と直交する方向に対応する幅をこれに対応する樹脂部材（３３）の幅とほぼ同じ長さで形成した構造であることにより、腕時計ケース側に位置する金属部材の端部の両側にそれぞれ形成された金属係合部が樹脂嵌合部に上面側から嵌合することにより、バンド本体を上面側から見たとき、金属部材が樹脂部材の幅方向における両側に存在した形状のものを得ることができる。
【００１３】
また、請求項６に記載の発明は、図５、図６または図１２、図１３に示すように、前記ピン部材（２５、２７または４５、４７）に段差部（段差凹部２５ａ、２７ａまたは４５ａ、４７ａ）が形成され、前記腕時計ケース側に位置する前記金属部材（１４または３２）の端部に、前記ピン部材の前記段差部に係脱可能に係合するピン係合部（係合フック部２６、絞り部２８、または係合フック部４６、絞り部４８）が形成された構造であれば、ピン係合部がピン部材の段差部に係合することにより、使用時にピン部材が勝手に抜け出さないようにすることができ、より一層、金属部材と樹脂部材とを確実に固定させることができる。
また、請求項７に記載の発明は、図７に示すように、前記樹脂部材（１５）が、ウレタン樹脂などの弾性を有する合成樹脂からなり、前記ピン部材（１６）が挿入する前記ピン挿入孔（２２）の内径（Ｒ１）を前記ピン部材の外径（Ｒ２）よりも相対的に小さく形成した構造であることにより、樹脂部材の弾性力によりピン部材を固定することができるので、簡単な構造で、使用時にピン部材が勝手に抜け出さないようにすることができ、これによっても金属部材と樹脂部材とを確実に固定させることができる。
【００１４】
【発明の実施の形態】
［第１実施形態］
以下、図１〜図４を参照して、この発明の腕時計バンドの第１実施形態について説明する。
図１は腕時計バンドを腕時計ケースに取り付けた状態の外観斜視図、図２はその要部の分解斜視図、図３はバンド本体の正面図、図４はバンド本体の要部の一部を分解した裏面図である。
この腕時計バンド１は、図１および図２に示すように、腕時計ケース２にバンド本体３を連結手段である先カン４により連結した構造のものである。
【００１５】
腕時計ケース２は、硬質の合成樹脂により薄型に形成されており、その上面には時計ガラス５が装着され、内部には液晶表示パネル６を有する時計モジュールが収納され、下面には裏蓋（図示せず）が取り付けられている。また、この腕時計ケース２の３時側の側面には押釦スイッチ７が設けられており、１２時側および６時側の各側面にはそれぞれバンド取付部８が一体に形成されている。この場合、バンド取付部８の先端部には、それぞれ装着溝９がバンド取付部８の先端縁に沿い、かつその一端部（図２では右下側の端部）のみに連続して設けられている。この装着溝９は、後述する先カン４がバンド本体３の長手方向に抜けないように、内部側が外部側よりも大きい円形状で、外部側が内部側よりも小さい矩形状をなす断面形状に形成されている。
【００１６】
また、バンド本体３は、図２および図３に示すように、金属製のバンド駒１０を回動可能に順次連結した構造のものであり、腕時計ケース２側の端部（図２では右端部）には、アジャスト駒１１が連結されている。このアジャスト駒１１は、図４に示すように、金属板を中空のほぼ薄板状に折り曲げた駒本体１２と、この駒本体１２内に挿入する固定板１３とを備えている。この場合、駒本体１２の裏面側における中央部分には、開口部１２ａが設けられており、バンド本体３の長手方向と直交する方向における開口部１２ａの縁部には、切欠部１２ｂが設けられている。これにより、アジャスト駒１１は、バンド本体３のバンド駒１０の連結突起１０ａを駒本体１２の切欠部１２ｂから中空内に挿入させ、この状態で駒本体１２内に固定板１３を挿入させ、この固定板１３でバンド駒１０の連結突起１０ａを駒本体１２内に固定し、これによりバンド本体３に取り付けられている。なお、バンド本体３の端部には、図３に示すように、バンド本体３の端部同士を連結するバックル３ａが取り付けられている。
【００１７】
連結手段である先カン４は、図２に示すように、バンド本体３に連結される金属部材１４と、腕時計ケース２に連結される樹脂部材１５と、これら金属部材１４と樹脂部材１５を連結するピン部材１６とを備えている。
金属部材１４は、バンド本体３の長手方向と直交する方向に対応する幅が樹脂部材１５の幅よりも短く形成された金属板からなっている。この場合、腕時計ケース２側に位置する金属部材１４の右端部には、ピン部材１６が挿入するほぼ円筒状の金属係合部１７が湾曲形成されている。また、バンド本体３側に位置する金属部材の左端部は、これに対応する樹脂部材１５の左端部に沿って下側に向けて凹部状に折り曲げられている。この折り曲げられた上端部の両側には、バンド本体３のアジャスト駒１１に連結される連結突起１８が形成されており、また折り曲げられた下端部の両側には、ほぼＬ字状に折り曲げれた係止突起部１９がバンド本体３の長手方向と直交する方向に対応する幅方向にそれぞれ突出して形成されている。
【００１８】
また、樹脂部材１５は、ウレタン樹脂などの弾性を有する合成樹脂からなり、腕時計ケース２側の右端部には、腕時計ケース２のバンド取付部８に形成された装着溝９に圧入されて装着する連結挿入部２０が形成されている。すなわち、この連結挿入部２０は、バンド取付部８の装着溝９とほぼ同じ形状で、かつほぼ同じ大きさか、それよりも少し大きく形成され、この状態でバンド取付部８の装着溝９の一端部側（図２では右下側の端部側）から圧入されて挿入されることにより、腕時計ケース２のバンド取付部８に取り付けられる。また、この樹脂部材１５のほぼ中央部分には、その上面側から金属係合部１７が嵌合する樹脂嵌合孔２１が上下に貫通して形成されており、この樹脂嵌合孔２１におけるバンド本体３の長手方向と直交する方向に対応する幅方向に位置する箇所には、ピン部材１６が挿入するピン挿入孔２２が樹脂嵌合孔２１に嵌合した金属係合部１７の両端に対応して形成されている。また、バンド本体３側に位置する樹脂部材１５の左端部には、金属部材１４の係止突起部１９が樹脂部材１５の下面側から当接する当接凹部２３がそれぞれ形成されている。なお、これら以外に金属部材１４が対応する樹脂部材１５の箇所は、金属部材１４の厚みだけ凹んだ構造になっている。
【００１９】
次に、このような腕時計バンド１を腕時計ケース２に取り付ける場合について説明する。
まず、腕時計ケース２にバンド本体３を連結する先カン４の金属部材１４と樹脂部材１５とを相互に取り付ける。このときには、バンド本体３側に位置する金属部材１４の係止突起部１９をこれに対応する樹脂部材１５の当接凹部２３に下面側から当接させるとともに、金属部材１４の金属係合部１７を樹脂部材１５の樹脂嵌合孔２１に上面側から嵌合させる。すると、樹脂部材１５に形成されたピン挿入孔２２にほぼ円筒状の金属係合部１７の両端が対応する。この状態で、ピン部材１６をピン挿入孔２２から挿入させて金属係合部１７内に挿入し、このピン部材１６により金属係合部１７を樹脂嵌合孔２１内に取り付ける。これにより、金属部材１４と樹脂部材１５とが相互に取り付けられ、先カン４が組み立てられる。
【００２０】
この状態で、金属部材１４の連結突起１８をバンド本体３に連結されたアジャスト駒１１の駒本体１２内にその開口部１２ａおよび切欠部１２ｂから挿入させた後、固定板１３を駒本体１２内に挿入して金属部材１４の連結突起１８を駒本体１２内に固定する。これにより、金属部材１４がアジャスト駒１１に連結され、バンド本体３にアジャスト駒１１を介して金属部材１４と樹脂部材１５とからなる先カン４が取り付けられ、図３に示す腕時計バンド１が得られる。そして、この腕時計バンド１の先カン４の樹脂部材１５に形成された連結挿入部２０を腕時計ケース２のバンド取付部８に形成された装着溝９に一端部側から圧入させて挿入することにより、腕時計バンド１の先カン４が腕時計ケース２のバンド取付部８に取り付けられ、これにより腕時計バンド１が腕時計ケース２に取り付けられる。
【００２１】
この場合、腕時計バンド１の組み立て手順は、上記の手順に限らず、例えば、先カン４の金属部材１４のみを上記と同様にバンド本体３のアジャスト駒１１に取り付け、また先カン４の樹脂部材１５のみを上記と同様に腕時計ケース２のバンド取付部８に取り付け、この状態で金属部材１４と樹脂部材１５とを上記と同様に相互に装着させてピン部材１６で連結するようにしても良い。
【００２２】
このように、この腕時計バンド１によれば、金属部材１４の係止突起部１９を樹脂部材１５の当接凹部２３にその下面側から当接させるとともに、金属部材１４の金属係合部１７を樹脂部材１５の樹脂嵌合孔２１にその上面側から嵌合させ、この状態でピン部材１６を樹脂部材１５のピン挿入孔２２から挿入させて金属係合部１７内に挿入し、これにより金属部材１４と樹脂部材１５とを相互に取り付けたので、十分な強度を確保でき、これによりバンド全体の薄型化を図ることが可能になるほか、樹脂嵌合孔２１に嵌合された金属係合部１７がピン部材１６により樹脂部材１５に回動可能に連結されていても、金属部材１４の係止突起部１９が樹脂部材１５の当接凹部２３に当接していることにより、金属部材１４と樹脂部材１５とが相対的に回動することがないので、その両者を一体的に取り付けることができる。このため、金属部材１４と樹脂部材１５とを別体に形成したことにより、デザイン的な形状の制約が少なく、しかも金属部材１４と樹脂部材１５とを別体に形成しても、金属部材１４と樹脂部材１５とが一体的な構造のものを得ることができる。
【００２３】
また、この腕時計バンド１によれば、腕時計ケース２側に位置する金属部材１４の右端部に金属係合部１７をほぼ円筒状に湾曲形成するとともに、バンド本体３側に位置する金属部材１４の左端部に連結突起１８および係止突起部１９を形成した構造であるから、金属部材１４として、金属板を用いてプレス加工により容易に製作することができる。
さらに、この腕時計バンド１では、バンド本体３の長手方向と直交する方向に対応する金属部材１４の幅がこれに対応する樹脂部材１５の幅よりも短く形成されているので、腕時計ケース２側に位置する金属部材１４の端部に形成された金属係合部１７を樹脂部材１５の樹脂嵌合孔２１に上面側から嵌合させることにより、バンド本体３を上面側から見たとき、金属部材１４が樹脂部材１５の幅方向における両端側に存在せず、樹脂部材１５の中間部分に配置された形状のものを得ることができる。
【００２４】
なお、上記第１実施形態では、バンド本体３側に位置する金属部材１４の左端部に係止突起部１９をバンド本体３の長手方向と直交する方向に対応する幅方向にそれぞれ突出させて形成したが、これに限らず、例えば、金属部材１４の左端部の中間部に１つの係止突起部を切り起しにより形成した構造でも良い。
また、上記第１実施形態では、樹脂部材１５に金属部材１４の金属係合部１７が嵌合する樹脂嵌合孔２１を上下に貫通させて形成したが、これに限らず、例えば、樹脂部材１５に底部が塞がれた樹脂嵌合凹部を形成した構造でも良い。
【００２５】
さらに、上記第１実施形態では、金属部材１４と樹脂部材１５とを連結するピン部材１６が単なる丸棒状に形成され、このピン部材１６が樹脂部材１５のピン挿入孔２２および金属部材１４の金属係合部１７内に挿入されるだけの構造であるが、これに限らず、例えば、図５〜図７にそれぞれ示すような構造でも良い。すなわち、図５に示された第１変形例は、ピン部材２５の中間部分に段差凹部２５ａを形成し、金属部材１４の金属係合部１７の中間部にピン係合部である係合フック部２６を形成し、ピン部材２５を樹脂部材１５のピン挿入孔２２から挿入させて金属係合部１７内に挿入させたときに、ピン部材２５の段差凹部２５ａに金属係合部１７の係合フック部２６が係脱可能に係合する構造になっている。このような構造であれば、ピン部材２５の段差凹部２５ａに係合フック部２６が係合することにより、使用時にピン部材２５が勝手に抜け出さないようにすることができ、より一層、金属部材１４と樹脂部材１５とを確実に固定させることができる。
【００２６】
また、図６に示された第２変形例は、ピン部材２７の中間部分に緩やかに傾斜する段差凹部２７ａを形成し、金属部材１４の金属係合部１７の中間部にピン係合部である絞り部２８を形成して金属係合部１７の内面に凸部を形成し、ピン部材２７を樹脂部材１５のピン挿入孔２２から挿入させて金属係合部１７内に挿入させたときに、ピン部材２７の段差凹部２７ａに金属係合部１７の絞り部２８の凸部が係脱可能に係合する構造になっている。このような構造であっても、ピン部材２７の段差凹部２７ａに絞り部２８の凸部が係合することにより、使用時にピン部材２７が勝手に抜け出さないようにすることができ、これによっても、金属部材１４と樹脂部材１５とを確実に固定させることができる。
【００２７】
さらに、図７に示された第３変形例は、ウレタン樹脂などの弾性を有する合成樹脂からなる樹脂部材１５に形成されたピン挿入孔２２の内径Ｒ１をピン部材１６の外径Ｒ２よりも小さく形成するか、あるいはピン挿入孔２２の内径Ｒ１よりもピン部材１６の外径Ｒ２を大きく形成した構造になっている。このような構造であれば、ピン部材１６が樹脂部材１５のピン挿入孔２２に挿入されると、樹脂部材１５がその弾性力によりピン部材１６を挾持して固定することができるので、簡単な構造で、使用時にピン部材１６が勝手に抜け出さないようにすることができ、これによっても金属部材１４と樹脂部材１５とを確実に固定させることができる。
【００２８】
［第２実施形態］
次に、図８〜図１１を参照して、この発明の腕時計バンドの第２実施形態について説明する。なお、図１〜図４に示された第１実施形態と同一部分には、同一符号を付して説明する。
この腕時計バンド３０は、腕時計ケース２とバンド本体３とを連結する先カン３１の構造が第１実施形態と異なり、これ以外は第１実施形態とほぼ同じ構造になっている。
すなわち、先カン３１は、図８に示すように、バンド本体３に連結される金属部材３２と、腕時計ケース２に連結される樹脂部材３３と、金属部材３２と樹脂部材３３とを連結するピン部材３４とを備えている。
【００２９】
金属部材３２は、バンド本体３の長手方向と直交する方向に対応する幅が樹脂部材３３の幅とほぼ同じ長さに形成された金属板からなっている。この場合、腕時計ケース２側に位置する金属部材３２の右端部における両側には、図８および図１０に示すように、ピン部材３４が挿入するほぼ円筒状の金属係合部３５がそれぞれ湾曲形成されており、これら金属係合部３５の間に位置する金属部材３２の箇所には、バンド本体３側に位置する左端部に亘って切欠部３６が形成されている。また、バンド本体３側に位置する金属部材３２の左端部には、その両側から金属係合部３５の下端部側に向けて折り返され、かつ切欠部３６の両側に位置する端部同士を連結する連結押え部３７が形成されている。さらに、金属部材３２の左端部における両側には、バンド本体３のアジャスト駒３８に設けられた連結突起３９が挿入して係合するほぼコ字状の連結係合部４０がそれぞれ折り曲げられて形成されている。
【００３０】
また、樹脂部材３３は、第１実施形態と同様、ウレタン樹脂などの弾性を有する合成樹脂からなり、腕時計ケース２側の右端部には、図８および図１１に示すように腕時計ケース２のバンド取付部８に形成された装着溝９に圧入されて装着される連結挿入部２０が形成されている。また、この樹脂部材３３のほぼ中央部分における両側には、その上面側から金属係合部３５がそれぞれ嵌合する樹脂嵌合孔４１が上下に貫通して形成されており、この樹脂嵌合孔４１の幅方向に位置する箇所には、ピン部材３４が挿入するピン挿入孔４２が樹脂嵌合孔４１に嵌合した金属係合部３５の端面にそれぞれ対応して形成されている。また、バンド本体３側に位置する樹脂部材３３の左端部側における下面には、金属部材３２の連結押え部３７が下面側から当接する当接凹部４３が形成されている。さらに、バンド本体３側に位置する樹脂部材３３の左端部には、金属部材３２の連結係合部４０が嵌合する嵌合凹部４４が形成されている。なお、これら以外に金属部材３２が対応する樹脂部材３３の箇所は、金属部材３２の厚みだけ凹んだ構造になっている。
【００３１】
次に、このような腕時計バンド３０を腕時計ケース２に取り付ける場合について説明する。
この場合には、まず、バンド本体３のアジャスト駒３８に先カン３１の金属部材３２を連結する。このときには、バンド本体３に連結されたアジャスト駒３８の連結突起３９をバンド本体３側に位置する金属部材３２のほぼコ字状の連結係合部４０に挿入させて係合させ、これにより金属部材３２をアジャスト駒３８に連結する。
この状態で、バンド本体３側に位置する金属部材３２の連結押え部３７をこれに対応する樹脂部材３３の当接凹部４３に下面側から当接させるとともに、金属部材３２の金属係合部３５を樹脂部材３３の樹脂嵌合孔４１に上面側からそれぞれ嵌合させる。これにより、アジャスト駒３８の連結突起３９が金属部材３２のほぼコ字状の連結係合部４０から抜け出さないように樹脂部材３３の左端部で押えられる。
【００３２】
この状態では、樹脂部材３３に形成されたピン挿入孔４２にほぼ円筒状の金属係合部３５の端面が対応するので、ピン部材３４をピン挿入孔４２から挿入させて金属係合部３５内に挿入する。これにより、金属部材３２と樹脂部材３３とが互いに取り付けられ、バンド本体３にアジャスト駒１１を介して金属部材３２と樹脂部材３３とからなる先カン３１が取り付けられ、図９に示す腕時計バンド３０が得られる。
そして、この腕時計バンド３０の先カン３１の樹脂部材３３に形成された連結挿入部２０を腕時計ケース２のバンド取付部８に形成された装着溝９に一端部側から圧入させて挿入する。これにより、腕時計バンド３０の先カン３１が腕時計ケース２のバンド取付部８に取り付けられ、これにより腕時計バンド３０が腕時計ケース２に取り付けられる。
【００３３】
このように、この腕時計バンド３０によれば、金属部材３２の連結押え部３７を樹脂部材３３の当接凹部４３にその下面側から当接させるとともに、金属部材３２の金属係合部３５を樹脂部材３３の樹脂嵌合孔４１にその上面側から嵌合させてピン部材３４で相互に取り付けたので、第１実施形態と同様、十分な強度を確保でき、これによりバンド全体の薄型化を図ることが可能になるほか、樹脂嵌合孔４１に嵌合された金属係合部３５がピン部材３４により樹脂部材３３に回動可能に連結されていても、金属部材３２の連結押え部３７が樹脂部材３３の当接凹部４３に当接していることにより、金属部材３２と樹脂部材３３とが相対的に回動することがないので、その両者を一体的に取り付けることができる。このため、第１実施形態と同様、金属部材３２と樹脂部材３３とを別体に形成したことにより、デザイン的な形状の制約が少なく、しかも金属部材３２と樹脂部材３３とを別体に形成しても、金属部材３２と樹脂部材３３とが一体的な構造のものを得ることができる。
【００３４】
また、この腕時計バンド３０によれば、腕時計ケース２側に位置する金属部材３２の右端部に金属係合部３５をほぼ円筒状に湾曲形成するとともに、バンド本体３側に位置する金属部材３２の左端部に連結押え部３７および連結係合部４０を屈曲形成した構造であるから、第１実施形態と同様、金属部材３２として、金属板を用いてプレス加工により容易に製作することができる。
さらに、この腕時計バンド３０では、バンド本体３の長手方向と直交する方向に対応する金属部材３２の幅がこれに対応する樹脂部材３３の幅とほぼ同じ長さで形成され、かつ金属部材３２の幅方向における両側の金属係合部３５間に切欠部３６が形成されているので、腕時計ケース２側に位置する金属部材３２の端部における両側にそれぞれ形成された金属係合部３５を樹脂部材３３の樹脂嵌合孔４１内にその上面側からそれぞれ嵌合させていることにより、バンド本体３を上面側から見たとき、先カン３１の中間部分には金属部材３２の切欠部３６に対応して樹脂部材３３が露呈し、先カン３１の幅方向における両側には金属部材３２が配置された形状のものを得ることができる。
【００３５】
なお、上記第２実施形態では、予め、バンド本体３のアジャスト駒１１に連結突起３９が設けられている場合について述べたが、これに限らず、例えば、連結突起３９を金属部材３２のコ字状の連結係合部４０に配置して、この連結係合部４０をほぼ円筒状に湾曲させることにより、予め、連結突起３９を金属部材３２の連結係合部４０に取り付けておいても良い。このようにすれば、第１実施形態と同様、金属部材３２を樹脂部材３３に装着させ、その両者をピン部材３４で相互に取り付けた状態で、金属部材３２をバンド本体３のアジャスト駒１１に連結させることができ、これにより組立て手順を変えることができる。
また、上記第２実施形態においても、樹脂部材３３に金属部材３２の金属係合部３５が嵌合する樹脂嵌合孔４１を上下に貫通させて形成したが、これに限らず、例えば、樹脂部材３３に底部が塞がれた樹脂嵌合凹部をそれぞれ形成した構造でも良い。
【００３６】
さらに、上記第２実施形態でも、金属部材３２と樹脂部材３３とを連結するピン部材３４が単なる丸棒状に形成され、このピン部材３４が樹脂部材３３のピン挿入孔４２および金属部材３２の各金属係合部３５内に挿入されるだけの構造であるが、これに限らず、例えば、図１２または図１３にそれぞれ示すような構造でも良い。
すなわち、図１２に示された第２実施形態の第１変形例は、ピン部材４５の両側部分に段差凹部４５ａを形成し、金属部材３２の各金属係合部３５の中間部にそれぞれピン係合部である係合フック部４６を形成し、ピン部材４５を樹脂部材３３のピン挿入孔４２から挿入させて各金属係合部３５内に挿入させたときに、ピン部材４５の段差凹部４５ａに各金属係合部３５の係合フック部４６がそれぞれ係脱可能に係合する構造になっている。このような構造であれば、ピン部材４５の段差凹部４５ａに係合フック部４６が係合することにより、使用時にピン部材４５が勝手に抜け出さないようにすることができ、より一層、金属部材３２と樹脂部材３３とを確実に固定させることができる。
【００３７】
また、図１３に示された第２変形例は、ピン部材４７の両側部分に緩やかに傾斜する段差凹部４７ａを形成し、金属部材３２の各金属係合部３５の中間部にそれぞれピン係合部である絞り部４８を形成して各金属係合部３５の内面に凸部をそれぞれ形成し、ピン部材４７を樹脂部材３３のピン挿入孔４２から挿入させて各金属係合部３５内に挿入させたときに、ピン部材４７の各段差凹部４７ａに各金属係合部３５の絞り部４８の各凸部がそれぞれ係脱可能に係合する構造になっている。このような構造であれば、ピン部材４７の段差凹部４７ａに絞り部４８の凸部が係合することにより、使用時にピン部材４７が勝手に抜け出さないようにすることができ、これによっても、金属部材３２と樹脂部材３３とを確実に固定させることができる。
【００３８】
さらに、図示しないが、ウレタン樹脂などの弾性を有する合成樹脂からなる樹脂部材３３に形成されたピン挿入孔４２の内径をピン部材３４の外径よりも小さく形成するか、あるいはピン挿入孔４２の内径よりもピン部材３４の外径を大きく形成しても良い。このような構造であれば、樹脂部材３３がその弾性力によりピン部材３４を挾持して固定することができるので、簡単な構造で、使用時にピン部材３４が勝手に抜け出さないようにすることができ、これによっても金属部材３２と樹脂部材３３とを確実に固定させることができる。
【００３９】
［第３実施形態］
次に、図１４〜図１７を参照して、この発明の腕時計バンド５０の第３実施形態について説明する。この場合にも、図１〜図４に示された第１実施形態と同一部分には、同一符号を付して説明する。
この腕時計バンド５０は、腕時計ケース２とバンド本体３とを連結する先カン５１の構造が第１実施形態と異なり、これ以外は第１実施形態とほぼ同じ構造になっている。
すなわち、先カン５１は、図１４に示すように、バンド本体３に連結される金属部材５２と、腕時計ケース２に連結される樹脂部材５３と、金属部材５２と樹脂部材５３との間に介在される補助金属部材５４とを備えている。
【００４０】
金属部材５２は、金属板からなり、樹脂部材５３の下側に配置されている。この金属部材５２は、樹脂部材５３を補助金属部材５４と共に挾み付ける金属挾持部５５と、この金属挾持部５５で樹脂部材５３と共に挾み付けられた補助金属部材５４に係合する金属係合部５６と、バンド本体３のアジャスト駒１１に連結される金属連結部５７とが一体に形成されている。すなわち、金属挾持部５５は、図１４に示すように、金属部材５２のほぼ中間部分に位置し、バンド本体３の長手方向と直交する方向に対応する幅方向にそれぞれ延出され、この延出された部分がそれぞれ樹脂部材５３を補助金属部材５４と共に挾み付けるように上側に折り返された構造になっている。金属係合部５６は、金属部材５２の中間部分から腕時計ケース２側に少し突出し、そのほぼ中央部分に係合突起５８が切り起しにより形成されている。この場合、係合突起５８は、金属部材５２を樹脂部材５３に組み付ける前の状態のときに、樹脂部材５３から下側に向けて離れるように切り起されている。金属連結部５７は、バンド本体３側に位置する金属部材５２の左端部が上方に折り曲げられ、その両側に連結突起５９が幅方向にそれぞれ突出して形成されている。
【００４１】
樹脂部材５３は、第１実施形態と同様、ウレタン樹脂などの弾性を有する合成樹脂からなり、腕時計ケース２側に位置する右端部には、腕時計ケース２のバンド取付部８に形成された装着溝９に圧入されて装着する連結挿入部２０が形成されている。また、この樹脂部材１５の上面および幅方向の両側面には、金属部材５２の金属挾持部５５が嵌合する樹脂嵌合凹部６０が形成されている。さらに、樹脂部材５３の下面には、図１５に示すように、補助金属部材５４が配置される配置凹部６１が形成されており、この配置凹部６１における腕時計ケース２側に位置する右側部には、補助金属部材５４の係止凹部６２が形成されている。
補助金属部材５４は、図１４および図１５に示すように、樹脂部材５３の下面に形成された配置凹部６１に配置される金属板であり、その中央部分には、金属部材５２の係合突起５８に対応する四角形状の係止孔６３が上下に貫通して設けられており、腕時計ケース２側に位置する端部には、樹脂部材５３の配置凹部６１に形成された係止凹部６２に挿入して係止される係止突起６４が形成されている。
【００４２】
次に、このような腕時計バンド５０を腕時計ケース２に取り付ける場合について説明する。
まず、腕時計ケース２にバンド本体３を連結する先カン５１の金属部材５２と樹脂部材５３とを補助金属部材５４を介して取り付ける。このときには、金属部材５２の金属挾持部５５に樹脂部材５３を腕時計ケース２側から挿入させながら、樹脂部材５３の下面と金属挾持部５５との間に補助金属部材５４を差し込み、この補助金属部材５４を樹脂部材５３の配置凹部６１に配置させるとともに、補助金属部材５４の係止突起６４を配置凹部６１の係止凹部６２に挿入させて係止させた上、金属部材５２の金属挾持部５５を樹脂部材５３の樹脂嵌合凹部６０に嵌合させる。これにより、金属部材５２が樹脂部材５３に補助金属部材５４を介して装着され、金属部材５２の金属係合部５６が補助金属部材５４の係止孔６３に対応する。この状態で、図１７に示すように、金属係合部５６の係合突起５８を補助金属部材５４の係止孔６３に挿入するように折り曲げて係止孔６３内に係止させる。これにより、金属部材５２が樹脂部材５３に補助金属部材５４を介して取り付けられ、先カン５１が組み立てられる。
【００４３】
この状態で、第１実施形態と同様、金属部材５２の金属連結部５７に形成された連結突起５９をバンド本体３に連結されたアジャスト駒１１内に挿入させて固定する。これにより、金属部材５２がアジャスト駒１１に連結され、金属部材５２と樹脂部材５３とが補助金属部材５４を介して取り付けられた先カン５１がバンド本体３にアジャスト駒１１を介して取り付けられ、図１６に示す腕時計バンド５０が得られる。そして、この腕時計バンド５０の先カン５１の樹脂部材５３に形成された連結挿入部２０を腕時計ケース２のバンド取付部８に形成された装着溝９に一端部側から圧入させて挿入することにより、腕時計バンド５０の先カン５１が腕時計ケース２のバンド取付部８に取り付けられ、これにより腕時計バンド５０が腕時計ケース２に取り付けられる。
この場合にも、腕時計バンド５０の組み立て手順は、上記のような手順に限らず、例えば、金属部材５２をバンド本体３のアジャスト駒１１に上記と同様に取り付け、また樹脂部材５３を腕時計ケース２のバンド取付部８に上記と同様に取り付け、この状態で補助金属部材５４を介して金属部材５２と樹脂部材５３とを上記と同様に装着して取り付けるようにしても良い。
【００４４】
このように、この腕時計バンド５０によれば、金属部材５２の金属挾持部５５に樹脂部材５３を挿入させながら、この樹脂部材５３の下面と金属挾持部５５との間に補助金属部材５４を差し込んで、金属部材５２の金属挾持部５５を樹脂部材５３の樹脂嵌合凹部６０に嵌合させることにより、金属挾持部５５が樹脂部材５３を補助金属部材５４と共に挾み付け、この状態で金属係合部５６の係合突起５８を補助金属部材５４の係止孔６３内に折り曲げて係止させることにより、金属部材５２と樹脂部材５３とを補助金属部材５４を介して一体的に取り付けることができる。このため、第１実施形態と同様、金属部材５２と樹脂部材５３とを別体に形成したことにより、デザイン的な形状の制約が少なく、しかも金属部材５２と樹脂部材５３とを別体に形成しても、金属部材５２と樹脂部材５３とが一体的な構造のものを得ることができる。
【００４５】
特に、この腕時計バンド５０では、金属部材５２と樹脂部材５３との間に介在された補助金属部材５４の係止孔６３に金属係合部５６の係合突起５８を係合させているので、十分な強度を確保することができ、これによりバンド全体の薄型化を図ることが可能になる。この場合には、補助金属部材５４の係止突起６４が樹脂部材５３の配置凹部６１に設けられた係止凹部６２に挿入して係止され、この状態で補助金属部材５４の係止孔６３に金属係合部５６の係合突起５８が係合することにより、補助金属部材５４がバンド本体３の長手方向に対応する方向に動くことがないので、この補助金属部材５４を介して金属部材５２と樹脂部材５３とを確実かつ強硬に固定させることができる。
【００４６】
また、この腕時計バンド５０では、金属部材５２に金属挾持部５５を折り曲げにより形成するとともに、金属係合部５６の係合突起５８を切り起しにより形成し、かつこの金属部材５２に金属連結部５７を折り曲げにより形成した構造であるから、第１実施形態と同様、金属部材５２として、金属板を用いてプレス加工により容易に製作することができる。
さらに、この腕時計バンド５０では、バンド本体３の長手方向と直交する方向に対応する幅方向に金属部材５２の金属挾持部５５が延出されて折り返され、この折り返された部分が樹脂部材５３を挾んで、その上面および幅方向の両側面に形成された樹脂嵌合凹部６０に嵌合するので、バンド本体３を上面側から見たとき、先カン５１の金属挾持部５５の折り返された部分が樹脂部材３３の上面に配置された形状のものを得ることができる。
【００４７】
なお、上記第３実施形態では、金属部材５２と樹脂部材５３との間に補助金属部材５４を挾み込むように構成した場合について述べたが、これに限らず、例えば、補助金属部材５４を予め樹脂部材５３にインサート成形により一体に形成しても良い。また、補助金属部材５４を用いずに、例えば、樹脂部材５３の下面に、金属部材５２の係合突起５８が折り曲げられて押し込まれる凹部を直接形成しても良い。このようにすれば、補助金属部材５４を用いる必要がないので、部品点数を削減することができるほか、樹脂部材５３の下面に、補助金属部材５４が配置する配置凹部６１、および補助金属部材５４の係止突起６４が挿入する係止凹部６２を形成する必要がないので、樹脂部材５３の形状が単純になり、低価格なものを得ることができる。
【００４８】
［第４実施形態］
次に、図１８および図１９を参照して、この発明の腕時計バンド７０の第４実施形態について説明する。この場合にも、図１〜図４に示された第１実施形態と同一部分には、同一符号を付して説明する。
この腕時計バンド７０は、バンド本体７１と、その先端側の先カン部材７２とが第１実施形態と異なり、これ以外は第１実施形態とほぼ同じ構造になっている。
すなわち、バンド本体７１は、図１８に示すように、ウレタン樹脂などの弾性を有する合成樹脂により厚さが薄い帯状に形成されている。この場合、腕時計ケース２の一方（１２時側）のバンド取付部８側に位置するバンド本体７１には、尾錠７３および止め輪７４が取り付けられており、他方（６時側）のバンド取付部８側に位置するバンド本体７１には、尾錠７３のつく棒７３ａが挿入する係止孔７５がバンド本体７１の長手方向に沿って等間隔に設けられている。
【００４９】
先カン部材７２は、両側のバンド本体７１の各先端側にそれぞれ連結され、腕時計ケース２の各バンド取付部８にそれぞれ取り付けられるものであり、図１８に示すように、両側とも同じ構成になっている。すなわち、この先カン部材７２は、図１８および図１９に示すように、腕時計バンド２のバンド取付部８に取り付けられる第１連結部材７６と、バンド本体７１に連結される第２連結部材７７とを備え、第１連結部材７６と第２連結部材７７とが連結される構造になっている。
【００５０】
第１連結部材７６は、図１９に示すように、第１樹脂部材７８と第１金属部材７９とからなっている。第１樹脂部材７８は、ウレタン樹脂などの弾性を有する合成樹脂からなり、腕時計ケース２側に位置する右端部には、腕時計ケース２のバンド取付部８に形成された装着溝９に圧入されて装着される連結挿入部２０が形成されている。この第１樹脂部材７８のほぼ中央部分には、第１金属部材７９が嵌合する樹脂嵌合孔８０が上下に貫通して形成されており、バンド本体７１の長手方向と直交する方向に対応する第１樹脂部材７８の幅方向における樹脂嵌合孔８０の両側に位置する箇所には、第１ピン挿入孔８１が設けられている。第１金属部材７９は、金属板を筒状に折り曲げた構造で、第１樹脂部材７８の樹脂嵌合孔８０内に嵌合し、この状態で第１ピン挿入孔８１から挿入された第１ピン部材８２が挿入し、これにより第１樹脂部材７８に取り付けられる。また、バンド本体７１側に位置する第１樹脂部材７８の左端部には、第２連結部材７７の後述する第２金属部材８６の一部が嵌合する嵌合切欠部８３が形成されており、この嵌合切欠部８３の幅方向に位置する箇所には、第２ピン部材８４が挿入する第２ピン挿入孔８５が形成されている。
【００５１】
第２連結部材７７は、図１９に示すように、第２金属部材８６と第２樹脂部材８７とからなっている。第２金属部材８６は、金属板からなり、左右対称なほぼ凹状に形成されている。この第２金属部材８６は、バンド本体７１の長手方向と直交する方向に対応する幅が第１連結部材７６の第１樹脂部材７８に形成された嵌合切欠部８３の幅とほぼ同じ長さに形成されている。また、第２金属部材８６の中間部には、金属嵌合凹部８８が折り曲げられて形成されており、バンド本体７１の長手方向に対応する第２金属部材８６の金属嵌合凹部８８の両端部には、断面形状が横長の長方形状の角筒部８９、９０がそれぞれ折り曲げられて形成されている。
【００５２】
これら角筒部８９、９０は、その内部にスペーサ板９１がそれぞれ配置され、これらスペーサ板９１が角筒部８９、９０の各底板の中間部にそれぞれ形成された仕切突起９２により上方に押し上げられ、その各仕切突起９２を境にして角筒部８９、９０内に第２〜第４ピン挿入部９３〜９６が形成された構造になっている。この場合、腕時計ケース２側に位置する角筒部８９は、その先端側の一部が第１樹脂部材７８の嵌合切欠部８３に嵌合し、この状態で角筒部８９の第２ピン挿入部９３が第１樹脂部材７８の第２ピン挿入孔８５に対応し、これにより第２ピン部材８４が挿入するように構成されている。また、バンド本体７１側に位置する角筒部９０は、その先端側の一部がバンド本体７１の端部に設けられた取付凹部７１ａに嵌合し、この状態で角筒部９０の第４ピン挿入部９６がバンド本体７１の取付凹部７１ａに設けられた第４ピン挿入孔７１ｂに対応し、これにより第４ピン部材１００が挿入するように構成されている。
【００５３】
また、第２樹脂部材８７は、第１樹脂部材７８と同様、ウレタン樹脂などの弾性を有する合成樹脂からなり、全体が左右対称なほぼエ字状に形成され、バンド本体７１の長手方向と直交する方向に対応する幅が第１樹脂部材７８の幅とほぼ同じ長さに形成されている。すなわち、この第２樹脂部材８７は、第２金属部材８６の中間に位置する金属嵌合凹部８８に嵌合する角棒状の樹脂嵌合部９７と、この樹脂嵌合部９７の上記幅方向における両端にそれぞれ形成された角棒状の樹脂連結部９８とからなっている。各樹脂連結部９８は、各対向面が第２金属部材８６の幅方向の端面に対応し、バンド本体７１の長手方向に対応する長さが、第２金属部材８６の角筒部８９、９０に形成された各仕切突起９２間の長さとほぼ同じ長に形成され、これにより両側の角筒部８９、９０の各先端側の部分がそれぞれ腕時計ケース２側またはバンド本体７１側に突出するように構成されている。この場合、各樹脂連結部９８には、各角筒部８９、９０の各第３ピン挿入部９４、９５に第３ピン部材９９を挿入させるための第３ピン挿入孔１０１がそれぞれ形成されている。
【００５４】
次に、このような腕時計バンド７０を腕時計ケース２に取り付ける場合について説明する。
まず、腕時計ケース２にバンド本体７１を連結する先カン部材７２の第１、第２連結部材７６、７７をそれぞれ組み立てて、その両者を連結させる。
このときには、第１連結部材７６の第１樹脂部材７８に形成された樹脂嵌合孔８０に第１金属部材７９を嵌合させ、この状態で第１ピン部材８２を第１樹脂部材７８の第１ピン挿入孔８１から挿入させて第１金属部材７９に挿入させる。これにより、第１金属部材７９と第１樹脂部材７８とがに取り付けられ、第１連結部材７６が構成される。
【００５５】
また、第２連結部材７７の第２樹脂部材８７の樹脂嵌合部９７を第２金属部材８６の中間に位置する金属嵌合凹部８８に嵌合させて、第２樹脂部材８７の樹脂連結部９８を第２金属部材８６の幅方向に対応する各角筒部８９、９０に対応させる。すると、各樹脂連結部９８の第３ピン挿入孔１０１に各角筒部８９、９０の各第３ピン挿入部９４、９５がそれぞれ対応し、この状態で第３ピン部材９９を樹脂連結部９８の各第３ピン挿入孔１０１から角筒部８９、９０の各第３ピン挿入孔９４、９５に挿入する。これにより、第２金属部材８６と第２樹脂部材８７とが連結され、第２連結部材７７が構成される。
【００５６】
この状態では、第２連結部材７７の第２金属部材８６の両側に位置する各角筒部８９、９０の各先端部が第２樹脂部材８７の各樹脂連結部９８よりもバンド本体７１の長手方向に対応する方向に突出している。そして、第２金属部材８６の各角筒部８９、９０のうち、第１連結部材７６側に位置する角筒部８９の先端部を第１連結部材７６の第１樹脂部材７８の嵌合切欠部８３に嵌合させて、第２ピン部材８４を第１樹脂部材７８の第２ピン挿入孔８５から角筒部８９の第２ピン挿入孔９３に挿入する。これにより、第２金属部材８６と第１樹脂部材７８とが取り付けられ、第１連結部材７６と第２連結部材７７とが連結される。
【００５７】
この状態で、バンド本体７１側に位置する第２金属部材８６の角筒部９０の先端部をバンド本体７１の端部に形成された取付凹部７１ａに嵌合させて、第４ピン部材１００をバンド本体７１の第４ピン挿入孔７１ｂから角筒部９０の第４ピン挿入孔９６に挿入する。これにより、バンド本体７１に第２金属部材８６が第２樹脂部材８７と共に連結され、バンド本体７１に第１、第２連結部材７６、７７からなる先カン部材７１が取り付けられ、図１８に示す腕時計バンド７０が構成される。
この後、第１樹脂部材７６の連結挿入部２０を腕時計ケース２のバンド取付部８に形成された装着溝９に圧入させて挿入することにより、第１連結部材７６が腕時計ケース２のバンド取付部８に取り付けられ、これにより腕時計バンド７０が腕時計ケース２に取り付けられる。
【００５８】
この場合にも、腕時計バンド７０の組み立て手順は、上記のような手順に限らず、例えば、第１樹脂部材７８と第１金属部材７９とが取り付けられた第１連結部材７６を腕時計ケース２のバンド取付部８に取り付け、また第２金属部材８６と第２樹脂部材８７とが取り付けられた第２連結部材７７をバンド本体７１に取り付け、この状態で第２連結部材７７の第２金属部材８６の角筒部８９を第１連結部材７６の第１樹脂部材７８の嵌合切欠部８３に嵌合させて第２ピン部材８４により連結させることにより、第１連結部材７６と第２連結部材７７とを最後に連結するようにしても良い。
【００５９】
このように、この腕時計バンド７０によれば、第１連結部材７６の第１樹脂部材７８に形成された樹脂嵌合孔８０に第１金属部材７９を嵌合させて第１ピン部材８２で連結し、第２連結部材７７の第２金属部材８６に形成された金属嵌合凹部８８に第２樹脂部材８７の樹脂嵌合部９７を嵌合させて第３ピン部材９９により連結し、この状態で第２金属部材８６の角筒部８９の先端部を第１連結部材７６の第１樹脂部材７８の嵌合切欠部８３に嵌合させて第２ピン部材８４により連結し、これにより先カン部材７２を構成しているので、第１樹脂部材７８と第１金属部材７９、また第２樹脂部材８７と第２金属部材８６をそれぞれ一体的に取り付けることができる。このため、十分な強度を確保することができ、これによりバンド全体の薄型化を可能にし、かつ第１、第２連結部材７６、７７ごとにそれぞれ金属部材７９、８６と樹脂部材７８、８７とを別体に形成したことにより、デザイン的な形状の制約が少なく、しかも第１、第２連結部材７６、７７ごとにそれぞれ金属部材７９、８６と樹脂部材７８、８７とを別体に形成しても、金属部材７９、８６と樹脂部材７８、８７とが一体的な構造のものを得ることができる。
【００６０】
また、この腕時計バンド７０では、第２樹脂部材８７が、第２金属部材８６の金属嵌合凹部８８に嵌合する樹脂嵌合部９７と、この樹脂嵌合部９７のバンド本体７１の長手方向と直交する方向に対応する幅方向の両端に設けられて第２金属部材８６の各角筒部８９、９０の幅方向に配置される樹脂連結部９８とからなり、第２金属部材８６の各角筒部８９、９０が、第２樹脂部材８７の樹脂連結部９８から第１連結部材７６側またはバンド本体７１側に突出していることにより、第１連結部材７６と第２連結部材７７とを連結した状態では、第１、第２金属部材７９、８６が第１、第２樹脂部材７８、８７の中に所定間隔で存在する形状のものを得ることができ、このため合成樹脂製のバンド本体７１に適したものを得ることができる。

BACKGROUND OF THE INVENTION
The present invention relates to a wristwatch band.
[0002]
[Prior art]
As a wristwatch band, a structure in which a band body is connected to a wristwatch case by a tip can serving as a connecting means is known.
This type of wristwatch band is made of various materials such as a wristwatch case and a band body made of metal or synthetic resin, or a combination thereof, and is a connecting means to correspond to these materials. As the can, a structure having a combination of a metal member and a resin member is used.
For example, in a structure in which a mounting groove is formed in the band attaching portion of the wristwatch case along the tip thereof, and the connecting insertion portion of the front can is slid and mounted in this mounting groove, the material of the front can is urethane resin or the like It is necessary to use a synthetic resin having the above elasticity. However, if the tip can is made of only a synthetic resin, sufficient strength cannot be obtained, and it is necessary to reinforce with a metal member.
As a front can of such a wristwatch band, a conventional structure in which a metal member is wound around a resin member and integrated, or a metal member and a resin member are formed separately and connected by a pin member or the like. There is something.
[0003]
[Problems to be solved by the invention]
However, in the former wristwatch band, since the front can as the connecting means is a structure in which the metal member is wound around the resin member and integrated, both the metal member and the resin member are subjected to mutual shape restrictions, For this reason, there is a problem that the design shape is largely restricted.
Further, in the latter wristwatch band, since the tip can as a connecting means has a structure in which the metal member and the resin member are simply connected by the pin member, the metal member and the resin member are relatively rotated around the pin member. Therefore, there is a problem that a sense of unity between the metal member and the resin member cannot be obtained.
[0004]
An object of the present invention is to obtain a structure in which a metal member and a resin member are integrated even if the shape of the metal member and the resin member are separately formed even when the shape of the metal member and the resin member are formed separately.
[0005]
[Means for Solving the Problems]
In order to solve the above problems, the present invention has the following configuration.
In addition, the reference numerals of the drawings attached to the respective elements described in the section of each embodiment described later are attached to the respective constituent elements together with parentheses.

The connecting means includes a metal member (14 or 32) connected to the band body, a resin member (15 or 33) connected to the watch case, and a connecting member that connects the metal member and the resin member. (16 or 34)
The metal member includes a metal engagement portion (17 or 35) with which the connection member engages, and a metal engagement portion (the engagement protrusion 19 or the connection presser portion 37) that comes into contact with and is engaged with the resin member. ) And formed,
The resin member has a resin fitting portion (resin fitting hole 21 or 41) into which the metal engaging portion is fitted from one surface side, and a connecting attachment portion (pin insertion hole 22 or 42) to which the connecting member is attached. ) And a resin locking portion (abutting recess 23 or 43) with which the metal locking portion abuts from the other surface side of the resin member.
It is characterized by that.
[0006]
According to this invention, the metal engaging part of the metal member is brought into contact with the resin engaging part of the resin member from the other surface side of the resin member, and the metal engaging part of the metal member is the resin fitting part of the resin member. Since the connecting member attached to the connecting attachment portion of the resin member in this state is engaged with the metal engaging portion in this state, the metal member and the resin member are connected. Sufficient strength can be ensured, thereby making it possible to reduce the thickness of the entire band, and even if the metal engaging portion is pivotally connected to the resin member by the connecting member, the metal locking portion is made of resin. Since the metal member and the resin member do not rotate relative to each other by being in contact with the locking portion, both of them can be attached integrally. For this reason, the metal member and the resin member are separated from each other. Design shape by forming on the body Constraint less, moreover it is formed and the metal member and a resin member separately, and the metal member and the resin member can be obtained as an integral structure.
[0007]
As shown in FIGS. 1 to 4, the invention described in claim 2 is a wristwatch band (1) in which a band body (3) is coupled to a wristwatch case (2) via a coupling means (front can 4). ,

As a result, the metal member 52 is mounted on the resin member 53 via the auxiliary metal member 54, and the metal engaging portion 56 of the metal member 52 corresponds to the locking hole 63 of the auxiliary metal member 54. In this state, as shown in FIG. 17, the engagement protrusion 58 of the metal engagement portion 56 is bent so as to be inserted into the engagement hole 63 of the auxiliary metal member 54 and is engaged in the engagement hole 63. Thereby, the metal member 52 is attached to the resin member 53 via the auxiliary metal member 54, and the leading can 51 is assembled.
[0043]
In this state, as in the first embodiment, the connection protrusion 59 formed on the metal connection portion 57 of the metal member 52 is inserted into the adjustment piece 11 connected to the band body 3 and fixed. Thereby, the metal member 52 is connected to the adjustment piece 11, and the tip can 51 in which the metal member 52 and the resin member 53 are attached via the auxiliary metal member 54 is attached to the band body 3 via the adjustment piece 11, The watch band 50 shown in FIG. 16 is obtained.

Thus, according to the wristwatch band 50, the auxiliary metal member 54 is inserted between the lower surface of the resin member 53 and the metal holding portion 55 while the resin member 53 is inserted into the metal holding portion 55 of the metal member 52. Thus, by fitting the metal holding portion 55 of the metal member 52 into the resin fitting recess 60 of the resin member 53, the metal holding portion 55 holds the resin member 53 together with the auxiliary metal member 54, and in this state the metal engagement portion 55 The metal member 52 and the resin member 53 can be integrally attached via the auxiliary metal member 54 by bending and engaging the engagement protrusion 58 of the joint portion 56 in the engagement hole 63 of the auxiliary metal member 54. it can. For this reason, as in the first embodiment, the metal member 52 and the resin member 53 are formed separately, so that there are few restrictions on the design shape, and the metal member 52 and the resin member 53 are formed separately. Even in this case, it is possible to obtain a structure in which the metal member 52 and the resin member 53 are integrated.
[0045]
In particular, in the wristwatch band 50, the engagement protrusion 58 of the metal engagement portion 56 is engaged with the engagement hole 63 of the auxiliary metal member 54 interposed between the metal member 52 and the resin member 53. Sufficient strength can be ensured, which makes it possible to reduce the thickness of the entire band. In this case, the locking protrusion 64 of the auxiliary metal member 54 is inserted and locked into the locking recess 62 provided in the arrangement recess 61 of the resin member 53, and in this state, the locking hole 63 of the auxiliary metal member 54. Since the auxiliary metal member 54 does not move in a direction corresponding to the longitudinal direction of the band body 3 by engaging the engaging protrusion 58 of the metal engaging portion 56 with the metal engaging portion 56, the metal member is interposed via the auxiliary metal member 54. 52 and the resin member 53 can be reliably and firmly fixed.
[0046]
In the wristwatch band 50, the metal holding portion 55 is formed by bending the metal member 52, and the engagement protrusion 58 of the metal engagement portion 56 is formed by cutting up and the metal connection portion is formed on the metal member 52. Since 57 has a structure formed by bending, the metal member 52 can be easily manufactured by pressing using a metal plate as in the first embodiment.
Further, in this wristwatch band 50, the metal holding portion 55 of the metal member 52 is extended and folded in the width direction corresponding to the direction orthogonal to the longitudinal direction of the band body 3, and the folded portion serves as the resin member 53. Since it rubs and fits into the resin fitting recess 60 formed on the upper surface and both side surfaces in the width direction, when the band body 3 is viewed from the upper surface side, the folded portion of the metal holding portion 55 of the tip can 51 Can be obtained in a shape arranged on the upper surface of the resin member 33.
[0047]
In the third embodiment, the case where the auxiliary metal member 54 is configured to be sandwiched between the metal member 52 and the resin member 53 has been described. The resin member 53 may be formed in advance by insert molding. Further, without using the auxiliary metal member 54, for example, a concave portion into which the engagement protrusion 58 of the metal member 52 is bent and pushed may be directly formed on the lower surface of the resin member 53. In this case, since it is not necessary to use the auxiliary metal member 54, the number of parts can be reduced, and the arrangement recess 61 in which the auxiliary metal member 54 is arranged on the lower surface of the resin member 53, and the auxiliary metal member 54. Since it is not necessary to form the locking recess 62 into which the locking protrusion 64 is inserted, the shape of the resin member 53 is simplified, and a low-cost one can be obtained.
