【０００１】
【発明の属する技術分野】
本発明は、手首に巻回されて装着される装身具に使用される中留構造であって、特に、皮バンド、布バンド、合成樹脂バンド、金属製メッシュバンド等の柔軟な装身帯を使用した装身具に適した中留構造に関する。
【０００２】
【従来の技術】
従来のこの種の装身具の中留構造として、特開平６−３２７５０８号公報に開示されたものがある。この開示技術は、図２２及び図２３に示すように係合ピン８０Ａを有する下板部材８０とこの下板部材８０の一端部に連結ピン８１で折曲可能に連結された中板部材８２とから構成された中折れ部材７９を備えており、下板部材８０の他端部には他方のバンド部材８３が連結してある。そして、中板部材８２の端部には上板部材８４が設けてあり、この上板部材８４のバンド短手方向の両端部には側壁部８４Ａが形成してあり、これらの側壁部８４Ａには開口部８４Ｂが形成してある。そして、両側壁部８４Ａ間には、バンド短手方向に沿う両端部が開口したボックス状の収納部材８５が取り付けてあり、この収納部材８５の両端部の開口部８５Ａが開口部８４Ｂに合致している。そして、上板部材８４の裏面部と収納部材８５との間には空間Ｈが設けてある。また、上板部材８４には突棒９３が、その基端側のピン９３Ａを支点にして回動可能に設けてある。
【０００３】
そして、収納部材８５には、一方及び他方のプッシュボタン８６、８７がそれぞれ挿入してあって、一方のプッシュボタン８６の元側ばね受け部８８と他方のプッシュボタン８７の先側ばね受け部８９との間及び一方のプッシュボタン８６の先側ばね受け部８９と他方のプッシュボタン８７の元側ばね受け部８８との間に、それぞれ前記スプリング９０が介装してあり、これらのスプリング９０の付勢力により一方及び他方のプッシュボタン８６、８７は互いに離間されていて、一方のプッシュボタン８６のストッパ部９１はプッシュボタン装入部８５の一方の開口部８５Ａの縁部に、他方のプッシュボタン８７のストッパ部９１はプッシュボタン装入部８５の他方の開口部８５Ａの縁部にそれぞれ当接している。そして、一方及び他方のプッシュボタン８６、８７の係合部９４は互いに対向していて、これらでボタン側係合部を構成している。また、プッシュボタン８６、８７の押圧部９５が開口部８４Ｂ外方に突出している。
【０００４】
そして、調整孔９６を有する一方のバンド部材９７を空間Ｈに挿入し、突棒９３を調整孔９６に挿入して長さ調整して係止し、腕時計を手首に沿わせた後に、中板部材８２を、これの下板部材８０との連結部を支点にして、この下板部材８０に重ね合わせ、係合ピン８０Ａを、収納部材８５の裏側に設けた孔部（図示せず）に挿入し、この係合ピン８０Ａを一方及び他方の前記プッシュボタン８６、８７の互いに対向する係合部９５に係合して前記腕時計が手首に装着される。
【０００５】
【発明が解決しようとする課題】
しかしながら、上記従来の時計バンドの中留構造にあっては、上板部材８４の下面と収納部材８５の上面との空間Ｈは上下方向に狭く、この空間Ｈ内に一方のバンド部材９７が挿通しにくかった。逆に、空間Ｈを上下方向に広くすると、一方のバンド部材９７の調整孔９６より突棒９３が脱落し易くなっていた。
また、一方のバンド部材９７の調整孔９６に突棒９３を挿入するのに、逐一突棒９３を回動させなければならず、操作が面倒であるという問題点があった。
【０００６】
さらに、突棒９３が回動するので、調整孔９６との位置合わせが極めて困難であった。特に、図中、Ｔで示される方向に一方のバンド部材９７が引っ張られると、このバンド部材９７の移動に連動して突棒９３が回動してしまい、よって、調整孔９６より突棒９３が抜けてしまう。したがって、一方のバンド部材９７は引っ張られると前記空間Ｈより容易に抜けて外れてしまうという問題点があった。
【０００７】
本発明は上記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、一方の装身帯と上板部材とを確実に固定できるし、また、一方の装身帯と前記上板部材とを容易に分離することもできるばかりか、一方の装身帯を開口部に極めて容易に挿通することができる装身具の中留構造を提供することにある。
【０００８】
【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、請求項１の発明に係わる装身具の中留構造は、調整孔を有する一方の装身帯と、他方の装身帯と、他方の装身帯に折り畳み可能に連結された下板部材と該下板部材の端部に折り畳み可能に連結された中板部材を有する中折れ部材と、この中折れ部材の前記中板部材の端部に回動可能に連結された上板部材とを有し、かつ前記下板部材と前記上板部材との間に、前記下板部材と前記上板部材を係脱可能に係合する共に、プッシュボタンの押圧操作により前記下板部材と前記上板部材との係合を解除できるプッシュ中留機構を具備する装身具の中留構造において、前記上板部材の基端部にその基端部で回転自在に連結されて、その先端部を前記上板部材より離間する方向に立ち上がらせた開放位置と、その先端部を前記上板部材に向けて倒した閉鎖位置とが設定可能な表板と、前記表板に設けられて一方の装身帯を挿通してこの一方の装身帯を前記上板部材上方に位置させるための開口部と、閉鎖位置にある前記表板の裏面と前記上板部材の面部との間に形成されて、一方の装身帯を挿通し且つ保持する空間と、閉鎖位置にある前記表板を前記上板部材に係脱可能に係合する係脱機構と、前記上板部材の面部に突設されて一方の装身帯の前記調整孔に係合する突棒とを備えたことを特徴とする。
【０００９】
かかる構成により、前記開口部より挿通されて前記上板部材の上方に位置した一方の装身帯の前記調整孔に前記突棒が挿入されて一方の装身帯と前記突棒とが係合される。一方の装身帯は前記突棒との係合により平面方向に沿った移動を抑止される。
【００１０】
次いで、前記表板を回転させて閉鎖位置に位置させ、前記係脱機構により前記表板と前記上板部材とを係合させる。すると、前記表板により、一方の装身帯は上方への移動を抑止される。このようにして、前記表板の裏面と前記上板部材の面部との間に形成される前記空間内に一方の装身帯が係止され、この一方の装身帯は前記上板部材に固定される。
【００１１】
また、一方の装身帯と前記上板部材とを分離するには、前記係脱機構の係合を解除し、前記表板を回転させて開放位置に位置させる。一方の装身帯を上方へ移動させ、前記調整孔と前記突棒との係合を解除する。このようにして、一方の装身帯を、前記開口部より前記空間外へ抜き出すと、一方の装身帯は前記上板部材より分離する。
【００１２】
したがって、前記表板を回転させて閉鎖位置に位置させ、前記係脱機構により前記表板と前記上板部材とを係合させることにより、一方の装身帯と前記上板部材とを確実に固定できる。また、前記係脱機構の係合を解除し、前記表板を回転させて開放位置に位置させると、一方の装身帯と前記上板部材とを容易に分離することもできる。さらに、開放位置では、前記開口部が前記上板部材より離間する方向に立ち上がり、広く口を開けているので、一方の装身帯を前記開口部に極めて容易に挿通することができる。
【００１３】
また、上記の目的を達成するために、請求項２の発明に係わる装身具の中留構造は、請求項１記載の装身具の中留構造において、前記係脱機構を、前記上板部材と前記表板のいずれか一方に配され且つ弾性部材により外方に付勢され前記上板部材の外表面に対して出没可能なロック部材と、他方に配されて前記ロック部材が係脱可能に係合する係合孔とより構成した。
【００１４】
かかる構成により、上記した請求項１の発明の作用と同様な作用を奏し得る。
【００１５】
また、上記の目的を達成するために、請求項３の発明に係わる装身具の中留構造は、請求項１記載の装身具の中留構造において、前記係脱機構を、前記上板部材と前記表板のいずれか一方に配された係脱突起と、他方に配されて係脱突起が係脱可能に係合する係合凹部とより構成した。
【００１６】
かかる構成により、上記した請求項１の発明の作用と同様な作用を奏し得る。
【００１７】
また、上記の目的を達成するために、請求項４の発明に係わる装身具の中留構造は、請求項１記載の装身具の中留構造において、前記上板部材と前記表板との間に、常に前記表板を開放位置に向けて付勢するトーションばねが設けられていることを特徴とする。
【００１８】
かかる構成により、上記した請求項１の発明の作用と同様な作用を奏し得るばかりか、前記係脱機構の係合を解除すると、前記トーションばねの弾発力によって、前記表板が自ら開放位置に移動するし、この開放位置に位置した前記表板は、前記トーションばねの弾発力によって、開放位置を維持し続け、その自重により、前記閉鎖位置に向けて移動することがない。
【００１９】
したがって、一方の装身帯を上方へ移動させ、前記調整孔と前記突棒との係合を解除する操作、及び一方の装身帯を前記開口部より前記空間外へ抜き出す操作を容易にする。このために、前記係脱機構の係合を解除さえすれば、一方の装身帯をより容易に前記上板部材から分離することができる。
【００２０】
また、上記の目的を達成するために、請求項５の発明に係わる装身具の中留構造は、請求項１記載の装身具の中留構造において、前記上板部材と前記表板との間に、常に前記表板を閉鎖位置に向けて付勢するトーションばねが設けられていることを特徴とする。
【００２１】
かかる構成により、上記した請求項１の発明の作用と同様な作用を奏し得るばかりか、前記係脱機構の係合を解除しても、前記トーションばねの弾発力によって、前記表板は、前記閉鎖位置を維持し続ける。
【００２２】
したがって、予期せぬ外力の負荷により、前記係脱機構の係合が解除されても、前記トーションばねの弾発力によって、前記表板は閉鎖位置を維持し続けるので、一方の装身帯の前記調整孔と前記突棒との係合が解除されない。このために、一方の装身帯と前記上板部材とがより確実に固定される。
【００２３】
また、上記の目的を達成するために、請求項６の発明に係わる装身具の中留構造は、請求項１記載の装身具の中留構造において、前記上板部材の前記中板部材との連結部に、前記中板部材に向けて且つ前記中板部材の表方に位置する押え突起が設けられていることを特徴とする。
【００２４】
かかる構成により、上記した請求項１の発明の作用と同様な作用を奏し得るばかりか、前記押え突起の下面が前記中板部材の上面と当接することにより、前記上板部材が前記中板部材の上面に向かって回転することを抑制する。このために、前記表板の開口部に、一方の装身帯を挿通する時、前記上板部材が前記中板部材の上面に向かって回転し、前記開口部を塞ぐことがない。よって、前記表板の開口部に、一方の装身帯をより容易に挿通することができる。
【００２５】
また、上記の目的を達成するために、請求項７の発明に係わる装身具の中留構造は、請求項１記載の装身具の中留構造において、前記表板に設けられた装身帯の短手方向の側壁部に、前記プッシュボタンにおける装身帯の短手方向に沿って突出した押圧部が挿入されるボタン挿入用切欠け部を設けた。
【００２６】
かかる構成により、上記した請求項１の発明の作用と同様な作用を奏し得るばかりか、前記表板の側壁と、前記プッシュボタンの押圧部とを装身帯の短手方向に向く同一平面上に重なる位置にすることができて、装身具の中留本体の上下の厚みを薄くすることができる。
【００２７】
また、上記の目的を達成するために、請求項８の発明に係わる装身具の中留構造は、請求項１記載の装身具の中留構造において、前記中折れ部材が、前記下板部材の他端部に、他方の装身帯が回転自在に連結され且つ前記中板部材が少なくとも１枚から成る複数折れ中留構成である。
【００２８】
かかる構成により、上記した請求項１の発明の作用と同様な作用を奏し得るばかりか、従来の中留構造とほぼ同じ製品化が可能になる。
【００２９】
また、上記の目的を達成するために、請求項９の発明に係わる装身具の中留構造は、請求項１記載の装身具の中留構造において、前記中折れ部材が、前記下板部材の一端部に一方の中板部材の一端部を、前記下板部材の他端部に他方の中板部材の一端部をそれぞれ折り畳み可能に連結し、一方の中板部材の他端部に前記上板部材を回転自在に連結し、他方の中板部材の他端部に他方の装身帯を回転自在に連結した観音開き中留構成である。
【００３０】
かかる構成により、上記した請求項１の発明の作用と同様な作用を奏し得るばかりか、従来の中留構造とほぼ同じ製品化が可能になる。
【００３１】

【００３６】
前記上板部材１０は中留本体１３を有しており、この中留本体１３はボックス１４と裏蓋１５とより構成されている。このボックス１４には、図８に示すようにその裏面側にバンド短手方向に沿う凹部１６と、その裏面より一段低くして裏蓋装着部１７とが形成してあり、凹部１６の中央部には孔部１８が設けてある。また、ボックス１４の基端部（右端部）にはバンド短手方向に沿うピン孔１９が形成してあり、また、ボックス１４の基端部の中央部には連結用切欠き部２０が形成してある。ボックス１４の一方の側端面１４ａの先端（左端）側にはロックピン挿入孔部２１が設けてある。
【００３７】
そして、ボックス１４の裏蓋装着部１７には、中央部に孔部１５Ａを有する裏蓋１５が装着してあって、この裏蓋１５と凹部１６とでバンド短手方向に沿うプッシュボタン装入部２２が形成してあり、このプッシュボタン装入部２２の両端は開口している。プッシュボタン装入部２２内には、対角に位置させて２本の抜け止めピン２３Ａ、２３Ｂが取り付けてあり、プッシュボタン装入部２２にプッシュボタン機構部２４が設けてある。そして、このプッシュボタン機構部２４と下板部材２が有する係合ピン７とでプッシュ中留機構Ａを構成している。
【００３８】
プッシュボタン機構部２４は一方及び他方のプッシュボタン２５、２６と、２個のスプリング２７とを備えており、一方及び他方のプッシュボタン２５、２６は、端部に押圧部２８Ａを形成したボタン本体２８を有しており、このボタン本体２８の先部の一側には切欠き部２９が形成してあって、この切欠き部２９の先側に円弧形状の係合部３０が、ボタン本体２８の元側にはストッパ部３１がそれぞれ形成してあり、また、ボタン本体２８には、一側に位置する元側ばね受け部３２と他側に位置する先側ばね受け部３３とが形成してある。
【００３９】
そして、プッシュボタン装入部２２には、一端側から一方のプッシュボタン２５が、他端側から他方のプッシュボタン２６がそれぞれ挿入してあって、一方のプッシュボタン２５の元側ばね受け部３２と他方のプッシュボタン２６の先側ばね受け部３３との間及び一方のプッシュボタン２５の先側ばね受け部３３と他方のプッシュボタン２６の元側ばね受け部３２との間に、それぞれ前記スプリング２７が介装してあり、これらのスプリング２７の付勢力により一方及び他方のプッシュボタン２５、２６は互いに離間されていて、一方のプッシュボタン２５のストッパ部３１は一方の抜け止めピン２３Ａに、他方のプッシュボタン２６のストッパ部３１は他方の抜け止めピン２３Ｂにそれぞれ当接している。
【００４０】
そして、一方及び他方のプッシュボタン２５、２６の係合部３０は互いに対向していて、これらでボタン側係合部を構成している。また、プッシュボタン２５、２６の押圧部２８Ａが、プッシュボタン装入部２２外方に突出している。
【００４１】
また、ボックス１４の一方の側端面１４ａのロックピン挿入孔部２１には弾性部材であるコイルスプリング３４とロック部材であるロックピン３５とが挿入してあり、このロックピン３５はコイルスプリング３４により押されていて、ロックピン３５の先端部がスリーブ３５ａを介してロックピン挿入孔部２１より外方に突出している。また、ボックス１４の表面部１ａの先側には突棒３６が突設してある。
【００４２】
連結部材１１は上板部材１０と一方の中板部材３との連結部として存在しており、この連結部材１１は、図１０に示すように駒本体１１Ａに互いに離間する２個のピン孔３７、３８をバンド短手方向に有し且つ駒本体１１Ａの外面側に押え突起３９を形成したものである。
【００４３】
そして、連結部材１１は、その一方のピン孔３７を使用して一方の中板部材３の右端部に連結ピン１２により回動可能に取り付けてあり、また、連結部材１１は、上板部材１０のボックス１４の連結用切欠き部２０に挿入してあって、この連結部材１１は、その他方のピン孔３８とボックス１４のピン孔１９とに挿入した連結ピン３９Ａによりボックス１４に回動可能に連結してある。
【００４４】
また、前記表板４０は、図９に示すように上板部材１０の先側を覆う面部４１のバンド短手方向の両端部に側壁部４２を設けてこの側壁部４２の端部をバンド長手方向に延長して取付部４３を形成して面部４１に平面視で略コ字形状の切欠き部４７を並設したものであり、両側壁部４２には長方形状のボタン挿入用切欠き部４４が形成してあり、一方の側壁部４２の先側には係合孔であるロック用孔４５が設けてあり、また、取付部４３にはピン孔４６が設けてある。そして、このピン孔４６に前記連結ピン３９Ａの両端部を挿入して表板４０の基端部が上板部材１０の基端部に回動可能に取り付けてあり、表板４０の切欠き部４７と上板部材１０とで開口部Ｓが形成してある。
【００４５】
そして、前記表板４０を、解放位置（その先端部を上板部材１０より離間する方向に立ち上がらせた位置）イから上板部材１０側に回動して、この表板４０のロック用孔４５に上板部材１０の側端面に配したロックピン３５を係合した状態、すなわち表板４０を閉鎖位置（その先端部を上板部材１０に向けて倒した位置）ロに設定すると、表板４０の下面（裏面部）と上板部材１０の上面（面部）との間に空間Ｈが形成される。このとき、プッシュボタン２５、２６の押圧部２８Ａが表板４０の側壁部４２のボタン挿入用切欠き部４４に挿入する。
【００４６】
次に、上記のように構成された中留構造を組み付けた装身具である時計バンド構造の操作方法を説明する。
【００４７】
図１１の（１）、（２）に示すように、まず、前記表板４０を回転して開放位置イに位置し、この表板４０と上板部材１０との間の開口部Ｓに、一方のバンド部材５０を挿通し、このバンド部材５０を上板部材１０の上方に位置する。
【００４８】
次に、図１１の（３）に示すように携帯者の手首の太さに合わせて選択された、一方のバンド部材５０の調整孔５０Ａに突棒３６を挿入し、このバンド部材５０と突棒３６とを係合して、一方のバンド部材５０の長さを調整する。ここで、一方のバンド部材５０は、その長手方向及び短手方向に沿った移動が抑止される。しかしながら、この段階では、一方のバンド部材５０は上方へ移動可能であり、一方のバンド部材５０が上方へ移動すると、調整孔５０Ａより突棒３６が抜け出て、両者の係合が解除してしまう。
【００４９】
次に、図１１の（３）に示すように上板部材１０の側端面１４ａに配されたロックピン３５をピンセット等の治具Ｇにより、コイルスプリング３４の弾発力の抗しつつ押圧し、よって上板部材１０の側端面１４ａよりロックピン３５を没入する。このロックピン３５への押圧を維持させつつ、表板４０を回転して閉鎖位置ロに位置させる。同時にロックピン３５よりピンセット等の治具Ｇを離間する。
【００５０】
すると、コイルスプリング３４の弾発力により、ロックピン３５が上板部材１０の側端面１４ａより突出して、表板４０の側壁部４２に設けられたロック孔４５に挿入し、ロックピン３５がロック孔４５に係脱可能に係合する。よって、閉鎖位置ロにおいて、表板４０は上板部材１０に係合する。また、このとき、プッシュボタン２５、２６の押圧部２８Ａが表板４０の側壁部４２のボタン挿入用切欠き部４４に挿入する。
【００５１】
閉鎖位置ロに係止した表板４０により、一方のバンド部材５０は上方への移動が抑止される。よって、調整孔５０Ａより突棒３６が抜け出ることはなくなり、調整孔５０Ａと突棒３６との係合を確実に保持する。したがって、表板４０の下面と上板部材１０の上面との間に形成される空間Ｈ内に、一方のバンド部材５０が係止され、一方のバンド部材５０は上板部材１０と確実に固定される。
【００５２】
次に、上記のように構成されたプッシュ中留構造を備えた時計バンド構造を有する腕時計の装着及びこの装着の解除を説明する。
【００５３】
まず、装身具である腕時計を手首に沿わせた後に、他方の中板部材４を、これの下板部材２との連結部を支点にして、この下板部材２に重ね合わせることにより、この中板部材４を中板挿入用孔部５Ａに嵌合して、前記フック部６にフック係合部４９を係脱可能に係合する。
【００５４】
そして、一方の中板部材３を、これの下板部材２との連結部を支点にして、この下板部材２に重ね合わせることにより、この中板部材３を下板部材２の中板挿入用孔部５Ｂに嵌合して、下板部材２に設けた係合ピン７を、下板部材１０の裏蓋１５の孔部１５Ａに挿入し、この係合ピン７を前記ボタン側係合部、すなわち一方及び他方の前記プッシュボタン２５、２６の互いに対向する係合部３０に係合して、前記腕時計を手首に装着する。
【００５５】
前記係合ピン７の係合部３０への係合は、この係合ピン７の端部の傘部７ｂで、一方及び他方の前記プッシュボタン２５、２６の係合部３０間をバンド短手方向に互いに離間するように押し開き、係合ピン７の軸部７ａが挿入されると一方及び他方の前記プッシュボタン２５、２６の係合部３０が前記スプリング２７の付勢力により閉じて係合ピン７の軸部７ａに係合することで行われる。
【００５６】
また、前記腕時計を手首から外す場合には、一方及び他方のプッシュボタン２５、２６の押圧部２８Ａを親指と人差し指で挟んで内側に押すことにより、一方及び他方のプッシュボタン２５、２６を前記スプリング２７に抗して移動させることにより前記係合部３０間を開いて係合を解除し、上板部材１０と一方の中板部材３を外に開いて前記係合ピン７を孔部１５Ａより抜き出し、他方の中板部材４を外に開いて、携帯者の手首から外す。
【００５７】
以上のように、本発明の中留構造は、図１２のようにプッシュ中留機構Ａによって、携帯者の手首に着脱するので、一度、一方のバンド部材５０を長さ調整して、上板部材１０と固定してしまえば、携帯者の手首の装着する都度、一方のバンド部材５０を上板部材１０より分離する必要はない。
【００５８】
しかしながら、一方のバンド部材５０が、鋭利な外力によって傷ついて、新品のバンド部材に交換したい場合などは、一方のバンド部材５０を上板部材１０と分離しなければならない。この場合は、前記表板４０のロック孔４５に係合しているロックピン３５をピンセット等の治具Ｇにより押圧して、このロックピン３５を没入して、ロックピン３５とロック孔４５との係合を解除する。
【００５９】
次いで、表板４０を回転させて開放位置イに位置させる。このことにより、一方のバンド部材５０の上方への移動が可能となり、このバンド部材５０を上方に移動して調整孔５０Ａより突棒３６を抜き出して、調整孔５０Ａと突棒３６との係合を解除する。そして、一方のバンド部材５０を開口部Ｓより空間Ｈ外へ抜き出すと、一方のバンド部材５０は上板部材１０と分離する。
【００６０】
また、表板４０の下面と上板部材１０の上面との間の上下方向の距離Ｌは、一方のバンド部材５０の上下方向の厚みＭの２倍未満であれば、一方のバンド部材５０が、空間Ｈ内でわずかに上方に向けて移動しようとも、突棒３６は調整孔５０Ａに留まり、抜け出ることはない。しかしながら、一方のバンド部材５０が、上下方向に柔軟に撓むことを考えれば、距離Ｌは、厚みＭの２倍未満であっても、大きければ大きいほど、突棒３６が調整孔５０Ａより抜け出る危険性を高める。また、一方のバンド部材５０の上下方向のガタつきは、甚だしく装身具の外観を損ねる。よって、距離Ｌは、図４に示すように厚みＭよりわずかに大きい程度にとどめることが好ましい。第１実施例では、距離Ｌは、厚みＭより０．４ｍｍ大きく設定した。
【００６１】
あるいは、距離Ｌは、厚みＭより小さくすることも可能である。すると、表板４０の下面と上板部材１０の上面との間で、一方のバンド部材５０が上下に圧縮されて固定されて、一方のバンド部材５０と上板部材１０との固定力を高めることも可能となる。
【００６２】
上記した第１実施例にあっては、一方及び他方のプッシュボタン２５、２６のプッシュ操作により前記プッシュボタン２５、２６の前記係合部３０と前記係合ピン７との係合を解除して、前記プッシュ中留機構Ａを前記下板部材２から外した場合に、この動作に連動して一方及び他方の中板部材３、４を前記下板部材２に対して拡開することができて、１回の操作で一方及び他方の中板部材３、４を観音開きすることができて、操作性が良好になる。
【００６３】
上記した第１実施例にあっては、前記表板４０を回転させて閉鎖位置ロに位置させ、ロックピン３５とロック孔４５との係合により表板４０と上板部材１０とを係合させることにより、一方のバンド部材５０と上板部材１０とを確実に固定できる。また、ロックピン３５とロック孔４５との係合を解除し、前記表板４０を回転させて開放位置イに位置させると、一方のバンド部材５０と上板部材１０とを容易に分離することもできる。さらに、開放位置イでは、前記開口部Ｓが上板部材１０より離間する方向に立ち上がり、広く口を開けているので、一方のバンド部材５０を前記開口部Ｓに極めて容易に挿通することができる。
【００６４】
また、上記した第１実施例では、前記上板部材１０に連結部材１１を回転可能に連結したが、回転不能に固定することもある。すると、一方の中板部材３に向けて且つ中板部材３の上方に位置する押え突起３９が設けられているために、この押え突起３９の下面が中板部材３の上面と当接することにより、上板部材２が中板部材３の上面に向かって回転することを抑制する。このために、前記表板４０の開口部Ｓに、一方のバンド部材５０を挿通する時、上板部材２が中板部材３の上面に向かって回転し、前記開口部Ｓを塞ぐことがない。よって、前記表板４０の開口部Ｓに、一方のバンド部材５０をより容易に挿通することができる。
【００６５】
また、前記表板４０の側壁部４２に、前記プッシュボタン２５、２６における押圧部２８Ａが挿入されるボタン挿入用切欠け部４４を設けたので、前記表板４０の側壁部４２と、前記プッシュボタン２５、２６の押圧部２８Ａとをバンド短手方向に向く同一平面上に重なる位置にすることができて、装身具の中留本体１３の上下の厚みを薄くすることができる。
【００６６】
なお、上記した第１実施例における係脱機構を、上板部材１０の側端面１４ａに設けたロックピン挿入孔部２１にコイルスプリング３４とロックピン３５とを収容して、このロックピン３５の先端部をロックピン挿入孔部２１より外方に突出し、表板４０の側壁部４２にロックピン３５が係脱可能に係合する係合孔であるロック用孔４５を設けて構成したが、表板４０の側壁部４２にロックピン３５を設け、上板部材１０の側端面１４ａにロックピン３５が係脱可能に係合するロック用孔４５を設けてもよい。
【００６７】
さて、上記した第１実施例における係脱機構は、ロックピン３５とロック孔４５との係合によるものであり、ピンセット等の治具Ｇを用いなければ解除できない強固な係合とした。これは、一方のバンド部材５０を上板部材１０より分離する必要は限られているため、一方のバンド部材５０と上板部材１０とを強固に固定する方が望ましいからである。
【００６８】
しかしながら、服装に合わせて、頻繁に一方及び他方のバンド部材５０、５１を、他の色調を有するバンド部材に交換したいというような要求を有する携帯者にとっては、係脱機構の係合はより弱いことが望まれる。これは、次の第２実施例で明らかとなろう。
【００６９】
（第２実施例）
本発明の第２実施例を図１３及び図１４に示す。この本発明の第２実施例にあっては、上記した本発明の第１実施例と異なるところは表板４０の係脱機構であり、他の構成及び作用は本発明の第１実施例と同じである。
【００７０】
表板４０の係脱機構は、上板部材１０の側端面１４ａに外方に突出する係合突起５２を設け、表板４０の側壁部４２の内側に係合突起５２が係脱可能に係合する係合凹部であるロック用凹部５３を設けて構成してある。前記係合突起５２はロックピン挿入孔部２１に圧入固定してあり、その突出量は、ロックピン３５の突出量より少なくしてある。したがって、係脱機構の係合はより弱いものになり、服装に合わせて、頻繁に一方及び他方のバンド部材５０、５１を、他の色調を有するバンド部材に交換するに際して、表板４０を回転させて開放位置イに位置させることが容易になる。
【００７１】
なお、上記した第２実施例における係脱機構を、上板部材１０の側端面１４ａに外方に突出する係合突起５２を設け、表板４０の側壁部４２の内側に係合突起５２が係脱可能に係合する係合凹部であるロック用凹部５３を設けて構成したが、表板４０の側壁部４２に係合突起５２を設け、上板部材１０の側端面１４ａに係合突起５２が係脱可能に係合するロック用部５３を設けてもよい。
【００７２】
（第３実施例）
本発明の第３実施例を図１５乃至図１８に示す。この本発明の第３実施例では、前記上板部材１０と前記表板４０との間に、常に表板４０を開放位置イに向けて付勢するトーションばね５４を設けたものであり、他の構成及び作用は本発明の第１実施例と同じである。
【００７３】
すなわち、前記上板部材１０のボックス１４の基端部のピン孔１９に挿入した連結ピン３９Ａの両端部に、表板４０の取付部４３のピン孔４６を取り付けて、この表板４０が上板部材１０に設けてあるが、前記上板部材１０のボックス１４の基端部の一方の角部に切欠き部５５を形成し、また、表板４０の取付部４３のピン孔４６の位置する部位の内面部に凹部５６を形成して、前記連結ピン３９Ａにトーションばね５４を装着して、このトーションばね５４の内端部５４Ａを切欠き部５５の壁部に引っ掛けると共に、トーションばね５４の外端部５４Ｂを凹部５６の壁部に引っ掛けて、このトーションばね５４の弾発力によって、表板４０を、常に開放位置イ側に付勢する。
【００７４】
前記係脱機構の係合を解除すると、すなわち、ロックピン３５をロック用孔４５より外すと、前記トーションばね５４の弾発力によって、前記表板４０が自ら開放位置イに移動し、この開放位置イに位置した前記表板４０は、前記トーションばね５４の弾発力によって、開放位置イを維持し続け、その自重により、前記閉鎖位置ロに向けて移動することがない。
【００７５】
したがって、一方のバンド部材５０を上方へ移動させ、前記調整孔５０Ａと前記突棒３６との係合を解除する操作、及び一方のバンド部材５０を前記開口部Ｓより前記空間Ｈ外へ抜き出す操作を容易にする。このために、前記係脱機構の係合を解除さえすれば、一方のバンド部材５０をより容易に前記上板部材１０から分離することができる。
【００７６】
（第４実施例）
本発明の第４実施例を図１９及び図２０に示す。この本発明の第４実施例では、前記上板部材１０と前記表板４０との間に、常に表板４０を閉鎖位置ロに向けて付勢するトーションばね５７を設けたものであり、他の構成及び作用は本発明の第１実施例と同じである。
【００７７】
すなわち、前記上板部材１０のボックス１４の基端部のピン孔１９に挿入した連結ピン３９Ａの両端部に、表板４０の取付部４３のピン孔４６を取り付けて、この表板４０が上板部材１０に設けてあるが、前記上板部材１０のボックス１４の基端部の一方の角部に切欠き部５５を形成し、また、表板４０の取付部４３のピン孔４６の位置する部位にこのピン孔４６より外して凹部５８を形成して、前記連結ピン３９Ａにトーションばね５７を装着して、このトーションばね５７の内端部５７Ａを切欠き部５５の壁部に引っ掛けると共に、トーションばね５７の外端部５７Ｂを凹部５８の壁部に引っ掛けて、このトーションばね５７の弾発力によって、表板４０を、常に閉鎖位置ロ側に付勢する。
【００７８】
前記係脱機構の係合を解除すると、すなわち、ロックピン３５をロック用孔４５より外すと、前記トーションばね５７の弾発力によって、前記表板４０は前記閉鎖位置ロを維持し続ける。
【００７９】
したがって、予期せぬ外力の負荷により、前記係脱機構の係合が解除されても、前記トーションばね５７の弾発力によって、前記表板４０は閉鎖位置ロを維持し続けるので、一方のバンド部材５０の調整孔５０Ａと前記突棒３６との係合が解除されない。このために、一方のバンド部材５０と上板部材１０とがより確実に固定される。
【００８０】
（第５実施例）
本発明の第５実施例を図２１に示す。上記した第１〜第４実施例においては、本発明の中留構造を観音開き構造の中折れ部材１を備えた時計バンド構造に取り付けた場合を説明したが、第５実施例では、本発明の中留構造を三つ折り構成の中折れ部材５９を備えた時計バンド構造に取り付けるものである。この三つ折り構成の中折れ部材５９は、係合ピン６０を有する下板部材６１とこの下板部材６１の一端部に連結ピン６２で折曲可能に連結された中板部材６３とから構成されており、下板部材６１の他端部には他方のバンド部材５１が連結してある。そして、中板部材６３の端部には上記した第１〜第４実施例と同様な構成の上板部材１０及び表板４０とが設けてある。
【００８１】
したがって、調整孔５０Ａを有する一方のバンド部材５０を空間Ｈに挿入し、突棒３６を調整孔５０Ａに挿入して長さ調整して係止し、腕時計を手首に沿わせた後に、中板部材６３を、これの下板部材６１との連結部を支点にして、この下板部材６１に重ね合わせ、係合ピン６０を、中板部材６３の孔部１５Ａに挿入し、この係合ピン６０を一方及び他方の前記プッシュボタン２５、２６の互いに対向する係合部３０に係合して前記腕時計が手首に装着される。
【００８２】
また、前記腕時計を手首から外す場合には、一方及び他方のプッシュボタン２５、２６の押し部２８Ａを親指と人差し指で挟んで内側に押すことにより、一方及び他方のプッシュボタン２５、２６を前記スプリング２７に抗して移動させて前記係合部３０間を開いて係合を解除し、上板部材１０を下板部材６１から外して前記係合ピン６０を孔部１５Ａより抜き出し、中板部材６３を外に開いて携帯者の手首から外す。
【００８３】
なお、以上の実施例においては、プッシュ中留機構Ａのプッシュボタン２５、２６を上板部材１０に、プッシュ中留機構Ａの係合ピン７、６０を下板部材２、６１に設けたが、互いに逆であってもかまわない。すなわち、プッシュ中留機構Ａは、上板部材１０と下板部材２、６１との間に備えられれば良く、プッシュボタン２５、２６を下板部材２、６１に、係合ピン７、６０を上板部材１０に設けることも可能である。
【００８４】

以上説明したように、請求項１の発明に係わる装身具の中留構造によれば、調整孔を有する一方の装身帯と、他方の装身帯と、他方の装身帯に折り畳み可能に連結された下板部材と該下板部材の端部に折り畳み可能に連結された中板部材を有する中折れ部材と、この中折れ部材の前記中板部材の端部に回動可能に連結された上板部材とを有し、かつ前記下板部材と前記上板部材との間に、前記下板部材と前記上板部材を係脱可能に係合する共に、プッシュボタンの押圧操作により前記下板部材と前記上板部材との係合を解除できるプッシュ中留機構を具備する装身具の中留構造において、前記上板部材の基端部にその基端部で回転自在に連結されて、その先端部を前記上板部材より離間する方向に立ち上がらせた開放位置と、その先端部を前記上板部材に向けて倒した閉鎖位置とが設定可能な表板と、前記表板に設けられて一方の装身帯を挿通してこの一方の装身帯を前記上板部材上方に位置させるための開口部と、閉鎖位置にある前記表板の裏面と前記上板部材の面部との間に形成されて、一方の装身帯を挿通し且つ保持する空間と、閉鎖位置にある前記表板を前記上板部材に係脱可能に係合する係脱機構と、前記上板部材の面部に突設されて一方の装身帯の前記調整孔に係合する突棒とを備えたことにより、前記表板を回転させて閉鎖位置に位置させ、前記係脱機構により前記表板と前記上板部材とを係合させることにより、一方の装身帯と前記上板部材とを確実に固定できる。また、前記係脱機構の係合を解除し、前記表板を回転させて開放位置に位置させると、一方の装身帯と前記上板部材とを容易に分離することもできる。さらに、開放位置では、前記開口部が前記上板部材より離間する方向に立ち上がり、広く口を開けているので、一方の装身帯を前記開口部に極めて容易に挿通することができる。
【００８５】
また、請求項２の発明に係わる装身具の中留構造によれば、請求項１記載の装身具の中留構造において、前記係脱機構を、前記上板部材と前記表板のいずれか一方に配され且つ弾性部材により外方に付勢され前記上板部材の外表面に対して出没可能なロック部材と、他方に配されて前記ロック部材が係脱可能に係合する係合孔とより構成したことにより、上記した請求項１の発明の効果と同様な効果を奏し得る。
【００８６】
また、請求項３の発明に係わる装身具の中留構造によれば、請求項１記載の装身具の中留構造において、前記係脱機構を、前記上板部材と前記表板のいずれか一方に配された係脱突起と、他方に配されて係脱突起が係脱可能に係合する係合凹部とより構成したことにより、上記した請求項１の発明の効果と同様な効果を奏し得る。
【００８７】
また、請求項４の発明に係わる装身具の中留構造によれば、請求項１記載の装身具の中留構造において、前記上板部材と前記表板との間に、常に前記表板を開放位置に向けて付勢するトーションばねを設けたことにより、上記した請求項１の発明の効果と同様な効果を奏し得るばかりか、前記係脱機構の係合を解除すると、前記トーションばねの弾発力によって、前記表板が自ら開放位置に移動するし、この開放位置に位置した前記表板は、前記トーションばねの弾発力によって、開放位置を維持し続け、その自重により、前記閉鎖位置に向けて移動することがない。
【００８８】
したがって、一方の装身帯を上方へ移動させ、前記調整孔と前記突棒との係合を解除する操作、及び一方の装身帯を前記開口部より前記空間外へ抜き出す操作を容易にする。このために、前記係脱機構の係合を解除さえすれば、一方の装身帯をより容易に前記上板部材から分離することができる。
【００８９】
また、請求項５の発明に係わる装身具の中留構造によれば、請求項１記載の装身具の中留構造において、前記上板部材と前記表板との間に、常に前記表板を閉鎖位置に向けて付勢するトーションばねを設けたことにより、上記した請求項１の発明の効果と同様な効果を奏し得るばかりか、前記係脱機構の係合を解除しても、前記トーションばねの弾発力によって、前記表板は、前記閉鎖位置を維持し続ける。
【００９０】
したがって、予期せぬ外力の負荷により、前記係脱機構の係合が解除されても、前記トーションばねの弾発力によって、前記表板は閉鎖位置を維持し続けるので、一方の装身帯の前記調整孔と前記突棒との係合が解除されない。このために、一方の装身帯と前記上板部材とがより確実に固定される。
【００９１】
また、請求項６の発明に係わる装身具の中留構造によれば、請求項１記載の装身具の中留構造において、前記上板部材の前記中板部材との連結部に、前記中板部材に向けて且つ前記中板部材の表方に位置する押え突起を設けたことにより、上記した請求項１の発明の効果と同様な効果を奏し得るばかりか、前記押え突起の下面が前記中板部材の上面と当接することにより、前記上板部材が前記中板部材の上面に向かって回転することを抑制する。このために、前記表板の開口部に、一方の装身帯を挿通する時、前記上板部材が前記中板部材の上面に向かって回転し、前記開口部を塞ぐことがない。よって、前記表板の開口部に、一方の装身帯をより容易に挿通することができる。
【００９２】
また、請求項７の発明に係わる装身具の中留構造によれば、請求項１記載の装身具の中留構造において、前記表板に設けられた装身帯の短手方向の側壁部に、前記プッシュボタンにおける装身帯の短手方向に沿って突出した押圧部が挿入されるボタン挿入用切欠け部を設けたことにより、上記した請求項１の発明の効果と同様な効果を奏し得るばかりか、前記表板の側壁と、前記プッシュボタンの押圧部とを装身帯の短手方向に向く同一平面上に重なる位置にすることができて、装身具の中留本体の上下の厚みを薄くすることができる。

The present invention relates to a retaining structure suitable for a given accessory.
[0002]
[Prior art]
As a conventional intermediate structure of this type of accessory, there is one disclosed in JP-A-6-327508. As shown in FIGS. 22 and 23, the disclosed technology includes a lower plate member 80 having an engagement pin 80A, and an intermediate plate member 82 that is foldably connected to one end of the lower plate member 80 by a connecting pin 81. The other bent member 83 is connected to the other end portion of the lower plate member 80. And the upper board member 84 is provided in the edge part of the middle board member 82, and the side wall part 84A is formed in the both ends of the band transversal direction of this upper board member 84, and these side wall parts 84A are formed in these side wall parts 84A. Has an opening 84B. And between both side wall parts 84A, the box-shaped storage member 85 which the both ends along a band transversal direction opened is attached, and the opening part 85A of the both ends of this storage member 85 corresponds to the opening part 84B. ing. A space H is provided between the back surface of the upper plate member 84 and the storage member 85. Further, the upper plate member 84 is provided with a projecting rod 93 so as to be rotatable about a pin 93A on the base end side as a fulcrum.
[0003]
One and the other push buttons 86 and 87 are inserted into the storage member 85, respectively, and the former spring receiving portion 88 of one push button 86 and the front spring receiving portion 89 of the other push button 87. The springs 90 are interposed between the front spring receiving portion 89 of one push button 86 and the original spring receiving portion 88 of the other push button 87, respectively. The one and the other push buttons 86 and 87 are separated from each other by the urging force, and the stopper portion 91 of the one push button 86 is disposed at the edge of the one opening 85A of the push button insertion portion 85 and the other push button. The stopper portion 91 of 87 is in contact with the edge of the other opening 85A of the push button insertion portion 85. The engaging portions 94 of the one and the other push buttons 86 and 87 are opposed to each other, and constitute a button side engaging portion. Further, the pressing portions 95 of the push buttons 86 and 87 protrude outward from the opening portion 84B.
[0004]
Then, one band member 97 having the adjustment hole 96 is inserted into the space H, the protruding rod 93 is inserted into the adjustment hole 96, the length is adjusted and locked, and the wristwatch is placed along the wrist. The member 82 is overlapped on the lower plate member 80 with the connecting portion with the lower plate member 80 as a fulcrum, and the engagement pin 80A is placed in a hole (not shown) provided on the back side of the storage member 85. The wristwatch is mounted on the wrist by inserting the engaging pin 80A into the engaging portions 95 of the push buttons 86 and 87 facing each other.
[0005]
[Problems to be solved by the invention]
However, in the above-described conventional watch band retaining structure, the space H between the lower surface of the upper plate member 84 and the upper surface of the storage member 85 is narrow in the vertical direction, and one band member 97 is inserted into this space H. It was difficult. On the contrary, when the space H is widened in the vertical direction, the protruding rod 93 is easily dropped from the adjustment hole 96 of one band member 97.
Further, in order to insert the protruding rod 93 into the adjustment hole 96 of one band member 97, the protruding rod 93 has to be rotated one by one, and there is a problem that the operation is troublesome.
[0006]
Furthermore, since the projecting rod 93 rotates, it is extremely difficult to align with the adjustment hole 96. In particular, when one band member 97 is pulled in the direction indicated by T in the drawing, the projecting rod 93 rotates in conjunction with the movement of the band member 97, and thus the projecting rod 93 is moved from the adjustment hole 96. Will come off. Therefore, when one band member 97 is pulled, there is a problem that it easily comes out of the space H and comes off.
[0007]
The present invention has been made paying attention to the above-mentioned problems, and the object of the present invention is to securely fix one of the garment belt and the upper plate member, and one of the garment belts. It is an object of the present invention to provide an intermediate structure for an accessory that can easily separate the upper plate member from the upper plate member and that allows one of the accessory bands to pass through the opening.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, the intermediate structure of the accessory according to the invention of claim 1 is foldable into one accessory band having an adjustment hole, the other accessory band, and the other accessory band.

The plate member 4 is fitted into the intermediate plate insertion hole 5A, and the hook engaging portion 49 is detachably engaged with the hook portion 6.
[0054]
Then, the middle plate member 3 is overlapped with the lower plate member 2 with the connecting portion with the lower plate member 2 as a fulcrum, thereby inserting the middle plate member 3 into the lower plate member 2. The engaging pin 7 fitted to the lower hole member 5B and provided in the lower plate member 2 is inserted into the hole portion 15A of the back cover 15 of the lower plate member 10, and the engaging pin 7 is engaged with the button side. The wristwatch is mounted on the wrist by engaging with the engaging portions 30 of the first and second push buttons 25 and 26 facing each other.
[0055]
The engagement pin 7 is engaged with the engagement portion 30 by the umbrella portion 7b at the end of the engagement pin 7 and between the engagement portions 30 of the one and the other push buttons 25, 26. When the shaft portion 7a of the engagement pin 7 is inserted, the engagement portions 30 of the one and the other push buttons 25, 26 are closed by the urging force of the spring 27 and engaged. This is done by engaging the shaft 7a of the pin 7.
[0056]
Further, when the wristwatch is removed from the wrist, the one and the other push buttons 25 and 26 are pushed inward by sandwiching the pressing portions 28A of the one and the other push buttons 25 and 26 between the thumb and the index finger. 27, the engagement portion 30 is opened to release the engagement, the upper plate member 10 and one middle plate member 3 are opened to the outside, and the engagement pin 7 is opened from the hole 15A. Pull out, open the other middle plate member 4 and remove it from the wrist of the wearer.
[0057]
As described above, since the middle structure of the present invention is attached to and detached from the wrist of the wearer by the push middle mechanism A as shown in FIG. 12, the length of one band member 50 is adjusted once, and the upper plate If fixed to the member 10, it is not necessary to separate the one band member 50 from the upper plate member 10 each time the wearer's wrist is worn.
[0058]
However, when one band member 50 is damaged by a sharp external force and is to be replaced with a new band member, one band member 50 must be separated from the upper plate member 10. In this case, the lock pin 35 engaged with the lock hole 45 of the front plate 40 is pressed by a jig G such as tweezers, and the lock pin 35 is immersed, so that the lock pin 35 and the lock hole 45 Release the engagement.
[0059]
Next, the front plate 40 is rotated to be positioned at the open position a. As a result, one band member 50 can be moved upward, the band member 50 is moved upward, the protruding rod 36 is extracted from the adjustment hole 50A, and the adjustment hole 50A and the protruding rod 36 are engaged. Is released. When one band member 50 is extracted from the opening S to the outside of the space H, the one band member 50 is separated from the upper plate member 10.
[0060]
If the distance L in the vertical direction between the lower surface of the front plate 40 and the upper surface of the upper plate member 10 is less than twice the vertical thickness M of the one band member 50, the one band member 50 is Even if it moves slightly upward in the space H, the projecting rod 36 remains in the adjustment hole 50A and does not come out. However, considering that one band member 50 bends flexibly in the vertical direction, even if the distance L is less than twice the thickness M, the larger the protrusion rod 36 comes out of the adjustment hole 50A. Increase the risk. Further, the backlash of one band member 50 in the vertical direction severely impairs the appearance of the accessory. Therefore, it is preferable to keep the distance L to be slightly larger than the thickness M as shown in FIG. In the first embodiment, the distance L is set to be 0.4 mm larger than the thickness M.
[0061]
Alternatively, the distance L can be smaller than the thickness M. Then, between the lower surface of the front plate 40 and the upper surface of the upper plate member 10, one band member 50 is compressed and fixed up and down to increase the fixing force between the one band member 50 and the upper plate member 10. It is also possible.
[0062]
In the first embodiment described above, the engagement between the engagement portion 30 of the push button 25, 26 and the engagement pin 7 is released by the push operation of one and the other push buttons 25, 26. When the push middle retaining mechanism A is removed from the lower plate member 2, one and the other middle plate members 3 and 4 can be expanded with respect to the lower plate member 2 in conjunction with this operation. Thus, one and the other middle plate members 3 and 4 can be opened in a single operation, and the operability is improved.
[0063]
In the first embodiment described above, the front plate 40 is rotated to be positioned at the closed position B, and the front plate 40 and the upper plate member 10 are engaged by the engagement between the lock pin 35 and the lock hole 45. By doing so, one band member 50 and the upper plate member 10 can be reliably fixed. Further, when the engagement between the lock pin 35 and the lock hole 45 is released and the front plate 40 is rotated to be positioned at the open position a, the one band member 50 and the upper plate member 10 can be easily separated. You can also. Furthermore, in the open position (a), the opening S rises in a direction away from the upper plate member 10 and has a wide opening, so that one band member 50 can be inserted into the opening S very easily. .
[0064]
In the first embodiment described above, the connecting member 11 is rotatably connected to the upper plate member 10, but may be fixed so as not to rotate. Then, since the presser protrusion 39 is provided toward the one intermediate plate member 3 and above the intermediate plate member 3, the lower surface of the presser protrusion 39 comes into contact with the upper surface of the intermediate plate member 3. The upper plate member 2 is prevented from rotating toward the upper surface of the middle plate member 3. For this reason, when one band member 50 is inserted into the opening S of the front plate 40, the upper plate member 2 does not rotate toward the upper surface of the middle plate member 3 and does not block the opening S. . Therefore, the one band member 50 can be more easily inserted into the opening S of the front plate 40.
[0065]
Further, since the button insertion notch 44 into which the pressing portion 28A of the push button 25, 26 is inserted is provided on the side wall 42 of the front plate 40, the side wall 42 of the front plate 40 and the push The pressing portions 28A of the buttons 25 and 26 can be placed on the same plane facing in the band short direction, and the upper and lower thicknesses of the intermediate body 13 of the accessory can be reduced.
[0066]
The engaging / disengaging mechanism in the first embodiment described above is configured such that the coil spring 34 and the lock pin 35 are accommodated in the lock pin insertion hole portion 21 provided in the side end surface 14a of the upper plate member 10, and the lock pin 35 is The front end portion protrudes outward from the lock pin insertion hole portion 21, and a lock hole 45, which is an engagement hole with which the lock pin 35 is detachably engaged, is provided on the side wall portion 42 of the front plate 40. The lock pin 35 may be provided on the side wall portion 42 of the front plate 40, and the lock hole 45 in which the lock pin 35 is detachably engaged may be provided on the side end surface 14 a of the upper plate member 10.
[0067]
The engaging / disengaging mechanism in the first embodiment described above is based on the engagement between the lock pin 35 and the lock hole 45, and is a strong engagement that cannot be released unless a jig G such as tweezers is used. This is because the necessity to separate one band member 50 from the upper plate member 10 is limited, and it is desirable to firmly fix the one band member 50 and the upper plate member 10.
[0068]
However, the engagement of the engagement / disengagement mechanism is weaker for a wearer who has a demand to frequently replace one and the other band members 50 and 51 with band members having other colors in accordance with clothes. It is desirable. This will become clear in the second embodiment.
[0069]
(Second embodiment)
A second embodiment of the present invention is shown in FIGS. In the second embodiment of the present invention, the difference from the first embodiment of the present invention described above is the engagement / disengagement mechanism of the front plate 40, and other configurations and operations are the same as those of the first embodiment of the present invention. The same.
