【０００１】
【発明の属する技術分野】
本発明は、時計ケースの両側部の相対する位置に設けられたバンド取付部にバンドを取り付ける時計用バンドの取付構造に関する。
【０００２】
【従来の技術】
従来のこの種の時計用バンドの取付構造として、実開昭５５−１５７４１７号公報に開示された技術がある。この時計用バンドの取付構造は、図７に示すように時計ケース５０の両側部に斜め下向きに突設されたバンド取付部５１を備えており、このバンド取付部５１は一対の係止部５２の上部に庇部５３を形成し、係止部５２に係止孔５４を形成したものである。また、バンド５５の基端部には、図８に示すように係止部５２間に挿入されるバンド側係止部５６が設けてあり、このバンド側係止部５６には、庇部５３の下面と時計ケース５０の外周部の当接する舌片部５７と、時計ケース５０に取り付けられた裏蓋５８に当接する当接部５９とが形成してあり、バンド側係止部５６には係止孔６０が設けてある。
【０００３】
そして、バンド側係止部５６の係止孔６０にバネ棒６１を挿通した状態で、このバンド側係止部５６を一対の係止部５２間に挿入して、このバンド側係止部５６の舌片部５７を庇部５３の下面と時計ケース５０の外周部に当接させ、当接部５９を裏蓋５８に当接させると共に、バネ棒６１の両端部のピボットを係止孔５４に係止してバンド５５がバンド取付部５１に取り付けてある。
【０００４】
【発明が解決しようとする課題】
上記した従来の時計用バンドの取付構造にあっては、腕時計を腕に装着した場合に、バンド５５には、図７の矢印方向に強い力（内方に向く力）が加わると、バンド５５と時計ケース５０、すなわち、バンド取付部５１の庇部５３との間に隙間Ｐができて、外観品質が悪いものになっていた。また、バンド５５の当接部５９が裏蓋５８に当接しているために、バンド５５をバンド取付部５１より外さないと、裏蓋５８の外し操作ができず、電池交換、モジュールの修理などを行う場合、作業性が悪かったし、皮バンドを時計ケースに隙間なく取り付けることができないという問題点があった。
【０００５】
本発明は、かかる従来の問題点に着目して成されたものであって、その目的とするところは、バンドに強い力が加わっても、時計ケースとバンドとの間に隙間ができ難く、且つ皮バンドの取り付けも可能で、通常の裏蓋と同様にバンドを外すことなくこの裏蓋を外すことができる時計用バンドの取付構造を提供することにある。
【０００６】
【課題を解決するための手段】
上記の目的を達成するために、本発明は、時計ケースの両側部の相対する位置に設けられたバンド取付部にバンドを取り付ける時計用バンドの取付構造において、前記バンド取付部を上部ケース側係止部と下部ケース側係止部とで構成し、前記上部ケース側係止部、前記下部ケース側係止部には係止孔を形成し、前記下部ケース側係止部の係止孔は、前記上部ケース側係止部の係止孔より時計ケースの中心からの距離が長く、かつ、前記上部ケース側係止部の係止孔は、前記下部ケース側係止部の係止孔より上方に位置するように設け、また、前記バンドに上部バンド側係止部と下部バンド側係止部とを設け、前記上部バンド側係止部、前記下部バンド側係止部には係止孔を形成し、前記上部バンド側係止部の係止孔と、前記上部ケース側係止部の係止孔を一致させた状態で係止部材を挿入し、また、
前記下部バンド側係止部の係止孔に挿入した係止部材で前記下部ケース側係止部の係止孔を係止することで、前記時計ケースと前記バンドとの密接状態を保持するようにしたことを特徴とする。
【０００７】
かかる構成により、腕時計を腕に装着した場合に、バンドには内方に力が加えられてバンドが引っ張られるが、バンドは、上部バンド側係止部を上部ケース側係止部に、下部バンド側係止部を下部ケース側係止部にそれぞれ係止部材により取り付けられていて、時計ケースとバンドの基端部とが密接状態に保持されているために、すなわち、取付位置の異なる２本の係止部材とによりバンド取付部に取り付けてあるために、バンドの基部は引張力に影響を受けず、このバンドの基端部と時計ケースの外周面との間には隙間は生じることがなく、外観品質を損なうことがなくなる。また、バンドを外すことなく、電池交換、モジュールの修理などを行うことができて、作業性を良くすることができる。
【０００８】
また、上記の目的を達成するために、本発明は、時計ケースの両側部の相対する位置に設けられたバンド取付部にバンドを取り付ける時計用バンドの取付構造において、前記バンド取付部を上部ケース側係止部と下部ケース側係止部とで構成し、前記上部ケース側係止部、前記下部ケース側係止部には係止孔を形成し、前記下部ケース側係止部の係止孔は、前記上部ケース側係止部の係止孔より時計ケースの中心からの距離が長く、かつ、前記上部ケース側係止部の係止孔は、前記下部ケース側係止部の係止孔より上方に位置するように設け、また、前記バンドの基部に係止孔を形成し、前記バンドを挿通するバンドガイドを有するカバー部材にカバー側係止部を設け、前記カバー側係止部に係止孔を形成し、前記バンドの基部の係止孔に挿入した係止部材で前記下部ケース側係止部の係止孔を係止し、前記バンドは前記バンドガイドに通し、また、前記カバー側係止部の係止孔と、前記上部ケース側係止部の係止孔を一致させた状態で係止部材を挿入したことを特徴とする。
【０００９】
かかる構成により、皮製の普通のバンドであっても、このバンドをカバー部材のバンドガイドに通して、カバー部材で包持することにより、時計ケースのバンド取付部に取り付けることができるし、また、カバー部材はバンドに働く引張力を受けないために、このカバー部材と時計ケースとの間には隙間は生じることがなく、外観品質を損なうことがなくなる。更に、バンドガイドにより、バンドの先端方向が規制されるので、バンドの手首への装着性が著しく向上する。また、バンドを外すことなく、電池交換、モジュールの修理などを行うことができて、作業性を良くすることができる。
【００１０】
そして、前記上部ケース側係止部と前記下部ケース側係止部とは、それぞれバンド取付構造が異なっていてもよいし、また、前記上部ケース側係止部と前記下部ケース側係止部とは、平面状態における前記時計ケースからの距離がそれぞれ異なった位置に設けられている。かかる構成により、バンド取付部のデザインバリェーションの拡大が図れる。また、時計ケースとバンドの基端部との間に隙間が生じることがなく、更に、皮バンドにおいては、違和感なく時計ケースに取り付けることができる。
【００１１】
また、前記上部ケース側係止部と前記下部ケース側係止部の少なくとも一方が前記バンドにより覆われていてもよいし、前記上部ケース側係止部が前記カバー部材により覆われていてもよい。かかる構成により、時計を平面的に見た場合、バンド取付部が２つ見えることがないので、違和感がなく、一般的な時計と同様の外観品質が得られ、デザインバリェーションの拡大が可能になる。また、前記係止部材は、バネ棒、ピン、割りパイプ、ヘアーピンのうちの少なくとも１つであればよい。
【００１２】
【発明の実施の形態】
以下、本発明の実施例を図面を参照して説明する。
【００１３】
（実施例１）
本発明に係る時計用バンドの取付構造の実施例１を図１乃至図３に示す。
図１は本発明に係る時計用バンドの取付構造を備えた腕時計の一部断面にした側面図、図２は同時計用バンドの取付構造の実施例１の分解状態の斜視図、図３はバンドの基部の裏側の斜視図である。なお、図面において、腕時計の９時−３時方向を左右方向、１２時−６時方向を前後方向とする。
【００１４】
腕時計Ａは時計ケース１を有しており、この時計ケース１は胴２とベゼル３とガラス縁部材４とから構成してある。そして、胴２内にはモジュール５が収容してあり、また、胴２の上側開口部２ａ側には風防ガラス６がパッキン７を介して嵌着してあり、また、胴２の上面部には、パッキン７の抜けを防止するガラス縁部材４が装着してある。そして、風防ガラス６の下方には時刻を表示する文字盤（表示パネル）８がモジュール５の上面に位置させて設けてあり、胴２の下側開口部２ｂ側に裏蓋１０が４本のネジにより取付けてある。
【００１５】
胴２の外周部の前後にはバンド取付部１４が形成してある。これらのバンド取付部１４は、上部ケース側係止部１５と下部ケース側係止部１６とを有している。そして、上部ケース側係止部１５は、胴２の外周部に上向きに突出した突起部９からなり、この上部ケース側係止部１５には左右方向に上部係止孔１７が形成してある。また、下部ケース側係止部１６は、斜め下方に向かって突出する前後一対のツノ足（突起部）１６Ａからなり、ツノ足１６Ａには左右方向に下部係止孔１８が形成してある。
【００１６】
したがって、上部ケース側係止部１５の上部係止孔１７の位置は、下部ケース側係止部１６の下部係止孔１８の位置より上方にあり、また、上部ケース側係止部１６の上部係止孔１７の位置と、下部ケース側係止部１６の下部係止孔１８の位置とは、平面視で時計ケース１の中心からの距離が異なり、時計ケース１の中心から下部係止孔１８までの距離が、時計ケース１の中心から上部係止孔１７までの距離より長くなっている。
【００１７】
バンド２０はウレタン等の合成樹脂で製作してあり、図３に示すように、その基部２０Ａの端縁部には、ベゼル３の外周面に密接（当接）する円弧状の密接面２０ｃが形成してあり、また、基部２０Ａの裏面には、上部バンド側係止部２１と下部バンド側係止部２２とが形成してある。
【００１８】
上部バンド側係止部２１は、バンド短手方向に互いに離れた一対の突起部２３を有しており、これらの突起部２３には、バンド短手方向に上部係止孔２４が形成してあり、また、突起部２３が密接面２０ｃに隣接して、突起部２３間には挿入凹部２３Ａが形成してあり、この挿入凹部２３Ａは上部ケース側係止部１５の円弧状の外面（突起部９の外面）が摺接するように曲面にしてある。
【００１９】
下部バンド側係止部２２はバンド短手方向に長い突起部２５を有しており、この突起部２５にはバンド短手方向に下部係止孔２６が形成してあって、この突起部２５は密接面２０ｃよりバンド長手方向に僅かに離れた位置にあり、上部係止孔２４と下部係止孔２６との間の距離は、上部ケース側係止部１５の上部係止孔１７と下部ケース側係止部１６の下部係止孔１８との間の距離に等しくしてある。また、突起部２５のバンド短手方向の寸法は、下部ケース側係止部１６の一対のツノ足（突起部）１６Ａ間の寸法よりやや小さくしてある。また、上部バンド側係止部２１の一対の突起部２３にそれぞれ形成された上部係止孔２４は、バンド２０の側面２０ａに形成された段付きピン孔２７に連通している。
【００２０】
そして、バンド２０の下部バンド側係止部２２の下部係止孔２６にバネ棒２８を挿入し、この下部バンド側係止部２２の突起部２５を下部ケース側係止部１６の一対のツノ足（突起部）１６Ａ間に挿入して、バネ棒２８の両端のピボット２８Ａをツノ足１６Ａの下部係止孔１８に係止する。そして、バンド２０の上部バンド側係止部２１の一対の突起部２３間の挿入凹部２３Ａに上部ケース側係止部１５の突起部９を挿入して上部係止孔１７、２４同士を一致させる。この状態で、上部係止孔１７、２４に割りパイプ２９を挿入し、バンド２０の側面２０ａの段付きピン孔２７に頭付きピン３０を両側より挿入して、これらの頭付きピン３０の軸部３０ａを割りパイプ２９の端部に圧入して、バンド２０がバンド取付部１４に取り付けてある。
【００２１】
この場合、バンド２０の基部２０Ａの密接面２０ｃはベゼル３の外周面に密接し、上部ケース側係止部１５の円弧状の外面が挿入凹部２３Ａに密接し、ツノ足１６Ａの外面がバンド２０の基部２０Ａの裏面のツノ足密接面部分２０ｄに密接する。この場合、下部バンド側係止部２２の突起部２５は裏蓋１０に干渉しないために、裏蓋１０の外し操作はバンド２０を外すことなく行うことができる。
【００２２】
腕時計Ａを腕に装着した場合に、バンド２０には、図１に示す矢印の方向（内方）に力が加えられてバンド２０が引っ張られる。しかし、バンド２０は、取付位置の異なる２本の係止部材、すなわち、割りパイプ２９とバネ棒２８とによりバンド取付部１４に取り付けてあるために、バンド２０の基部２０Ａは引張力に影響を受けず、このバンド２０の基部２０Ａの密接面２０ｃとベゼル３の外周面との間には隙間は生じない。このために、外観品質の低下がない。
【００２３】
（実施例２）
本発明に係る時計用バンドの取付構造の実施例２を図４乃至図６に示す。
図４は本発明に係る時計用バンドの取付構造を備えた腕時計の一部断面にした側面図、図５は同時計用バンドの取付構造の実施例２の分解状態の斜視図、図６はバンドの基部とカバー部材の裏側から見た斜視図である。
【００２４】
時計用バンドの取付構造の実施例２が上記した時計用バンドの取付構造の実施例１と異なるのは、そのバンドの構成とカバー部材を追加したことであり、時計ケース１の胴２の外周部に設けられたバンド取付部１４は同じであるので、このバンド取付部１４は、同じ符号を付して説明を省略する。
【００２５】
バンド３１は皮製であって、下部ケース側係止部１６の一対のツノ足（突起部）１６Ａ間に入る幅寸法を有しており、このバンド３１の基部３１Ａにはバンド短手方向に係止孔３２が形成してあり、この基部３１Ａの裏面には係止孔３２よりバンド長手方向に所定の距離おいて段部３３が形成してある。
【００２６】
また、カバー部材３４はウレタン等の合成樹脂で製作してあり、その裏面の一方の端縁部３４ｃには、ベゼル３の外周面に密接（当接）する円弧状の密接面３５が形成してあり、また、裏面には、カバ−側係止部３６とバンド通し部３７とが形成してある。
【００２７】
このカバ−側係止部３６は、バンド短手方向に互いに離れた一対の突起部３８を有しており、これらの突起部３８には、幅方向（バンド短手方向）に係止孔３９が形成してあり、また、突起部３８が密接面３５に隣接していて、突起部３８間には挿入凹部４０が形成してあり、この挿入凹部４０は上部ケース側係止部１５の円弧状の外面が摺接するように曲面にしてある。また、係止孔３９は、カバー部材３４の側面３４ａに形成された段付きピン孔４１に連通している。
【００２８】
また、バンド通し部３７は、カバー部材３４の他方の端縁部３４ｂ側で、カバー部材３４の側面３４ａに一体に形成してあり、バンド通し部３７とカバー部材３４の側面３４ａとを含めてバンドガイド３７Ａを形成している。
【００２９】
そして、バンド３１の係止孔３２にバネ棒４２を挿入し、このバンド３１の基部３１Ａを下部ケース側係止部１６の一対のツノ足（突起部）１６Ａ間に挿入して、バネ棒４２の両端のピボット４２Ａをツノ足１６Ａの下部係止孔１８に係止して、バンド３１がバンド取付部１４に取り付けてある。
【００３０】
そして、バンド３１の先側をカバー部材３４の裏側からバンドガイド３７Ａに通して、このカバー部材３４をバンド３１の基部３１Ａ側に移動し、カバー側係止部３６の挿入凹部４０に上部ケース側係止部１５の突起部９を挿入して、上部係止孔１７に係止孔３９を一致させる。この状態で、上部係止孔１７及び係止孔３９に割りパイプ４３を挿入し、カバー部材３４の側面３４ａに形成された段付きピン孔４１に頭付きピン４４を挿入して、これらの頭付きピン４４の軸部４４ａを割りパイプ４３の端部に圧入して、カバー部材３４がバンド取付部１４に取り付けてある。
【００３１】
この場合、カバー部材３４の密接面３５はベゼル３の外周面に密接し、上部ケース側係止部１５の突起部９の円弧状の外面が挿入凹部４０に密接する。そして、この場合、バンド３１の基部３１Ａは裏蓋１０に干渉していないために、裏蓋１０の外し操作はバンド３１を外すことなく行うことができる。
【００３２】
上記したように、皮製の普通のバンド３１であっても、このバンド３１をカバー部材３４の裏側からバンドガイド３７Ａに通して、カバー部材３４で包持することにより、上記した時計ケース１のバンド取付部１４に取り付けることができる。この場合、カバー部材３４はバンド３１に働く力を受けないために、このカバー部材３４の密接面３５とベゼル３の外周面との間には隙間は生じない。このために、外観品質の低下がない。
【００３３】
なお、上記した実施例１、２では上部ケース側係止部１５を１つの突起部９で構成し、下部ケース側係止部１６を一対のツノ足１６Ａで構成したが、上部ケース側係止部１５を２つの突起部で構成し、下部ケース側係止部１６を１つのツノ足で構成してもよいし、係止部材としては、バネ棒２８、４２及び割りパイプ２９、４３に限らず、ピン、ヘアーピンを使用してもよい。
【００３４】
【発明の効果】
本発明によれば、腕時計を腕に装着した場合に、バンドには内方に力が加えられてバンドが引っ張られるが、バンドは、取付位置の異なる２本の係止部材によりバンド取付部に取り付けてあるために、バンドの基部は引張力に影響を受けず、このバンドの基端部と時計ケースの外周面との間には隙間は生じることがなく、外観品質を損なうことがなくなる。
【００３５】
また、皮製の普通のバンドであっても、このバンドをカバー部材のバンドガイドに通して、カバー部材で包持することにより、時計ケースのバンド取付部に取り付けることができるし、また、カバー部材はバンドに働く引張力を受けないために、このカバー部材と時計ケースとの間には隙間は生じることがなく、外観品質を損なうことがなくなる。
【００３６】
また、バンドを外すことなく、電池交換、モジュールの修理などを行うことができて、作業性を良くすることができる。
