Description

【０００１】
【発明の属する技術分野】
本発明は、中留具、バンド、および装身具に関する。
【０００２】
【背景技術】
従来、装身具や時計において、一対の装着帯を備えて構成されるレザーバンドやウレタンバンド等の止め具としては、バンドを挿通する枠部材と、このバンドに孔設された調整孔に挿し通す突棒とを備えた尾錠が多く使用されている。尾錠は、構造が簡単なこともあり、各種デザインのものが提供されている。しかし、バンドの着脱を繰り返す調整孔の周囲が傷みやすく、また、金属バンドに使用される中留具に比べ、バンドの着脱がしにくいという課題があった。
【０００３】
そのため、装身具や時計のレザーバンドやウレタンバンド等の止め具としても、中留具を使用することが提案されている。
例えば、互いの一端同士が連結された二つ折れの中板部材および下板部材を用いるとともに、中板部材に上箱部材を連結し、調整孔を有する一方の装着帯を下板部材の端部に取り付けられている支え枠内に挿通し、下板部材の下面側の挿し止めピンを調整孔に挿し通して係止し、もう一方の装着帯を上箱に取り付けた中留具が知られている（例えば、特許文献１）。
また、上箱にプッシュ式の操作部を設け、この上箱に二つ折れの中留具を連結し、操作部の開閉止孔に係脱する係止用ピンを下板部材に設け、調整孔を有する一方の装着帯を下板部材の端部に形成した通し孔に挿入し、下板部材の下面側で挿し止めピンを調整孔に挿し通して係止し、もう一方の装着帯を上箱に取り付けた中留具が知られている（例えば、特許文献２）。
また、一端同士が連結された下板部材および中板部材を備え、その中板部材の他端に設けられた上板部材に尾錠を連結し、この尾錠で他方の装着帯を係止する中留具も知られている。なお、この中留具は、操作部を上板部材に備えている他、一対の中板部材を備えた観音開き式もある（例えば、特許文献３）。

実用新案第３０４６３９２号公報（図１、図２、図３）
【特許文献２】
実用新案第３０６１１９１号公報（図１、図２、図３）
【特許文献３】
特開平９−２０１２１３号公報（図１、図１３）
【０００５】
【発明が解決しようとする課題】
このような特許文献１や特許文献２の中留具では、上箱部材に二つ折れの下板部材および中板部材が連結され、調整孔を有する装着帯は、下板部材端部に設けられた支え枠、または通し孔を通して下板部材下面に向かって挿通され、挿し止めピンによって係止される構造であるために、中留具としてレザーバンドやウレタンバンド等に使用されている尾錠を用いることができず、尾錠付きバンドと同じ外観は得られない。また、腕に装着した際に、装着帯が下板部材下面側にあり、上箱部材が腕に対して最も外側に配置されているので、この点でも、尾錠付きバンドと同じ外観は得られない。
これらに対し、特許文献３の中留具では、上箱部材に取り付けられた尾錠内に装着帯を挿通させて、装着帯が係止される構造のために、一般の尾錠付のバンドと同等な外観が得られる。
しかし、尾錠に関して、これを構成する突棒や枠部材は当該尾錠用に専用に設計されたものであるため、一般的に用いられている尾錠を取り付けることができない。従って、このような中留具を用いた場合には、次のような問題がある。
すなわち、第１に、バンドの着脱性を容易にするために単なる尾錠付きのバンドを中留付きに変更する場合には、既設のバンドに用いられている尾錠をそのまま流用することができず、意匠性が損なわれる。つまり、バンドは通常、装着帯と尾錠とのトータルコーディネイトで全体がデザインされているため、本来の尾錠が使えないとデザイン的にアンバランスが生じるのである。
第２に、既にそのような中留具付きのバンドを使用している場合であって、装着帯等が老朽化した場合には、中留具が付いたバンドを丸ごと交換する必要があるため、広く市販されている尾錠付きのバンドを購入し、中留具を残したまま尾錠および装着帯のみを交換することができない。このため、交換に要する費用がかさんで不経済である。勿論、中留具が付いたバンドを購入し、装着帯のみを交換することも可能であるが、このような場合には、前記第１の問題が生じる。
【０００６】
本発明の目的は、尾錠付きバンドが本来有する意匠性を確実に維持でき、かつ装着帯等の交換を安価にできる中留具、バンド、および装身具を提供することにある。
【０００７】
【課題を解決するための手段】
本発明の中留具は、装身具に用いられる装着帯の第１端部および第２端部同士を連結するための中留具において、互いの一端同士が折り畳み自在に連結された中板部材および下板部材を備え、これら中板部材および下板部材のいずれか一方の部材の他端には、任意に選択された装着帯の第１端部が着脱自在に取り付けられる第１取付部が設けられ、前記中板部材および下板部材のいずれか他方の部材の他端には、任意に選択された尾錠が着脱自在に取り付けられる第２取付部が設けられ、この尾錠に他方の装着帯の第２端部側が係止されることを特徴とする。ここで、バンドとしては、レザーバンドやウレタンバンド等の柔軟性のある材料から形成されているバンドを採用することができる。
また、「任意に選択された装着帯」および「任意に選択された尾錠」とは、例えば市販されているバンドや、装身具にもともと付いているバンドの装着帯および尾錠のことをいう。
【０００８】
この発明によれば、中留具を構成する中板部材および下板部材の端部には、任意に選択された装着帯および尾錠が着脱自在に取り付けられる第１、第２取付部が設けられているので、例えば、バンドの着脱を容易にするために単なる尾錠付きのバンドを中留付きに変更する場合には、既設のバンドに用いられている装着帯および尾錠がそのまま流用されるようになり、尾錠付きバンドが本来保有する意匠性を確実に維持可能である。
また、装着帯等が老朽化した場合には、一般的に市販されている尾錠付きのバンドを購入し、中留具を残したまま尾錠および装着帯のみを交換すればよいから、中留具が付いたバンドを丸ごと新規に購入して交換する必要がなく、交換に要する費用が安価になる。
【０００９】
本発明の中留具は、装身具に用いられる装着帯の第１端部および第２端部同士を連結するための中留具において、一対の中板部材と、両端にこれら中板部材の一端が折り畳み自在に連結された下板部材とを備え、前記一対の中板部材のうちの一方の中板部材の他端には、任意に選択された装着帯の第１端部が着脱自在に取り付けられる第１取付部が設けられ、前記一対の中板部材のうちの他方の中板部材の他端には、任意に選択された尾錠が着脱自在に取り付けられる第２取付部が設けられ、この尾錠に他方の装着帯の第２端部側が係止されることを特徴とする。
この発明の中留具は、いわゆる観音開き式であるが、前述と同様な第１、第２取付部が設けられていることで、前述と同じ作用効果が得られる。
【００１０】
本発明の中留具では、前記中板部材および下板部材は、折り畳まれることで互いに係合するとともに、この中板部材または下板部材には、互いの係合状態を解除する操作部が設けられていることが好ましい。
このような発明によれば、中板部材または下板部材に互いの係合状態を解除する操作部を設けているので、バンドの着脱が容易である。なお、この操作部には、例えば、プッシュボタンの押し操作で各部材の係合状態を解除するプッシュ中留機構を採用することが好ましく、バンドの着脱がより容易になる。
【００１１】
本発明のバンドは、装身具本体に一方の端部が連結される一対の装着帯と、これら装着帯の他端同士を連結するための中留具とで構成されたバンドにおいて、前記中留具は、以上に説明したいずれかの中留具であることを特徴とする。
このような本発明によれば、このバンドは、装着帯同士が前述の中留具で連結されているので、古くなってバンドを交換したい場合には、装着帯および尾錠を中留具から外し、市販品の単なる尾錠付きのバンドの装着帯や尾錠と交換すればよく、着脱に便利な中留具をそのまま使用しながら、尾錠付きバンドが本来保有する意匠性が確実に維持され、また、交換に要する費用も安価になる。
【００１２】
本発明の装身具は、装身具本体に一方の端部が連結される一対の装着帯と、これら装着帯の他端同士を連結するための中留具とで構成されたバンドを有する装身具において、前記中留具は、以上に説明したいずれかの中留具であることを特徴とする。
このような発明の装身具も、前述したような中留具を連結したバンドを備えているために、古くなってバンドを交換したい場合には、装着帯および尾錠を中留具から外し、市販品の単なる尾錠付きのバンドの装着帯や尾錠と交換すればよく、尾錠付きバンドが本来保有する意匠性が確実に維持され、また、交換に要する費用も安価になる。
【００１３】
本発明の装身具において、時計であることを特徴とする。
常時身に着けている装身具としては時計がある。特に腕時計では、バンドとして尾錠付きのレザーバンドや中留付きの金属バンドが使われる。腕時計は、頻繁に着脱を繰り返すことが考えられるが、尾錠付きの外観を好み、かつ中留の使い易さを求める場合に本発明は有効であり、前述したような効果が得られる。
【００１４】
【発明の実施形態】
以下、各本実施形態を図面に基づいて説明する。
図１には、本発明の第１実施形態に係わる中留具、図２には、第１実施形態に係わる時計が示されている。図３には、第２実施形態に係わる中留具、図３には、第３実施形態に係わる中留具を示す。
【００１５】
〔第１実施形態〕
以下、本発明の第１実施形態に係わる中留具、バンド、時計について説明する。図１は、中留具の半開き状態を示す斜視図、図２は、第１実施形態に係わる時計（装身具）１の斜視図を示す。
図１において、時計１に用いられる中留具１０は、金属製の下板部材２０と、この下板部材２０に端部が連結された金属製の中板部材３０とを備えている。このような構成の中留具は、三つ折れ式中留具と呼ばれている。
【００１６】
下板部材２０は、例えば腕の外形に沿って湾曲した下板本体２０Ａを備えており、下板本体２０Ａの長手方向（湾曲方向）の一方の端部には、当該下板本体２０Ａの幅方向両側に突出した一対のバンド取付部（第１取付部）２０Ｂが形成されている。これらバンド取付部２０Ｂの先端はそれぞれ、下板本体２０Ａの上面２０Ｃ側に折り曲げられており、また、これらの先端部には、ばね棒６０のピンが挿通される挿通孔２０Ｄが穿設されている。ばね棒６０は、図示しないが、筒状に形成されたパイプ部材と、このパイプ部材の端部に進退可能に設けられたピンと、パイプ部材内に設けられて前記ピンを進出方向に付勢するばね部材とを備えたものになっている。一対のバンド取付部２０Ｂの間には、バンド３を構成する一方の装着帯４０の端部（第１端部）４０Ｂが挿入され、ばね棒６０で着脱可能に取り付けられている。
このような下板本体２０Ａは、平面幅が長手方向途中から中板部材３０との連結端に向かって徐々に狭く形成され、その先端には、下板本体２０Ａの上面２０Ｃ側に略円筒状に丸められた連結部２０Ｅが形成されている。連結部２０Ｅの内径は、中板固定軸７０の外径に対して回動可能な大きさとされる。下板本体２０Ａには、バンド取付部２０Ｂの近傍で上面２０Ｃ側が窪んだ凹部２０Ｆが形成され、この凹部２０Ｆにプッシュ中留機構９０が装着され、プッシュ中留機構９０を覆う押さえ板９１が下板本体２０Ａに固着されている。
【００１７】
プッシュ中留機構９０は、下板本体２０Ａの幅方向に突出して進退可能に装着された一対のプッシュボタン（操作部）９２を備え、また、図示しないが、内部には、プッシュボタン９２を進出側に付勢する図示略のばね部材を備え、プッシュボタン９２は、押さえ板９１に設けられた係止部９１Ａによって、進退方向の位置規制がなされている。
ここで、プッシュボタン９２の押し操作、操作解除で、プッシュボタン９２に設けられた係止片９２Ａと中板部材３０に設けられている係止軸３１との係脱で、中板部材３０の折り畳み係止と展開を行うことができる。
【００１８】
中板部材３０は、下板部材２０に沿って湾曲された中板本体３０Ａを備え、この中板本体３０Ａには、長手方向途中から下板部材２０との連結端部に向かって一対のアーム部３０Ｂが形成され、その端部には中板本体３０Ａの上面３０Ｃ側に略円筒状に曲げられた一対の連結部３０Ｄが形成されている。連結部３０Ｄの内径および外径は、下板部材２０の連結部２０Ｅと同じとされ、連結部３０Ｄの中空部に中板固定軸７０が挿入されている。この際、中板固定軸７０の長さは、連結部３０Ｄの外端長さよりもわずかに長く設定されている。また、連結部３０Ｄには、幅方向両側に突出した折曲した爪部３０Ｅが形成されている。
このような中板本体３０Ａの長手方向途中には、下板部材２０に向かって折り畳んだ際に、プッシュボタン９２の係止片９２Ａと係合する位置に係止軸３１が軸止されている。この係止軸３１には、傘部３１Ａが設けられている。
中板本体３０Ａのもう一方の端部には、上面３０Ｃ側に略円筒状に丸められた一対の尾錠取付部（第２取付部）３０Ｆが形成され、その内径は、ばね棒６０が遊嵌する大きささとされている。
【００１９】
以上の下板部材２０および中板部材３０で構成された中留具１０は、時計１に予め取り付けられていた尾錠８０付きのバンド３に後付けされたものであって、この中留具１０をバンド３に組み入れることにより、バンドの着脱を容易に行えるようにしてある。
【００２０】
バンド３にもともと使用されていた尾錠８０は、バンド３の全体的なデザインを考慮した形状、材質、色合いをそれぞれ有する枠部材８１と、突棒８２とを備えている。
尾錠８０の枠部材８１には、一対のアーム部８１Ａが形成され、その先端部には、ばね棒６０のピンが挿通されるピン挿通孔８１Ｂが対向して穿設されている。また、突棒８２には、貫通孔が穿設された突棒基部８２Ａと先端部８２Ｂが形成されている。この尾錠８０では、中板本体３０Ａの一対の尾錠取付部３０Ｆの両端部にアーム部８１Ａが取り付けられ、尾錠取付部３０Ｆの間には突棒基部８２Ａが取り付けられている。そして、尾錠取付部３０Ｆ、突棒基部８２Ａの孔を貫通してばね棒６０が挿通され、ばね棒６０のピンがピン挿通孔８１Ｂに挿入されて尾錠８０が着脱自在に取り付けられている。
このような尾錠８０には、バンド３を構成する他方の装着帯５０の端部（第２端部）５０Ｂが挿通され、突棒８２の先端部８２Ｂが任意の調整孔５０Ａに挿し通されて係止されている。
【００２１】
以下に、本実施形態の中留具１０の組み立て手順について説明する。
まず、下板本体２０Ａの凹部に一対のプッシュボタン９２とばね部材（図示しない）を装着し、押さえ板９１を溶接等の手段で下板本体２０Ａの上面２０Ｃに固着する。
続いて、下板本体２０Ａの連結部２０Ｅを中板部材３０の対向する一対の連結部３０Ｄの間に挿入し、中板固定軸７０を、それぞれの連結部２０Ｅ，３０Ｄの孔部に挿入する。次いで、中板部材３０の爪部３０Ｅを中板固定軸７０の両端部に当接するまで折り曲げ、中板固定軸７０が抜けるのを防止する。
【００２２】
次に、もともと尾錠８０のみが取り付けられたバンド３を本実施形態の中留具１０付きに変える手順について説明する。
まず、装着帯４０の尾錠８０側のばね棒６０を抜き外して、尾錠８０の枠部材８１、突棒８２を取り外す。次いで、中板部材３０の一対の尾錠取付部３０Ｆの対向面内に突棒８２の突棒基部８２Ａを配置し、これら尾錠取付部３０Ｆ、突棒基部８２Ａに設けられた孔に貫通してばね棒６０を挿通させる。次いで、枠部材８１のピン挿通孔８１Ｂをばね棒６０のピンに貫挿させて尾錠８０を中板部材３０に取り付ける。これにより、中板部材３０の尾錠取付部３０Ｆに枠部材８１、突棒８２をばね棒６０によって取り付ける。そして、装着帯４０の尾錠８０を取り外した端部を下板部材２０のバンド取付部２０Ｂに挿入し、別に用意したばね棒６０を装着帯４０のばね棒挿通孔に挿入して、装着帯４０を下板部材２０に取り付ける。さらに、他方の装着帯５０の先端部を尾錠８０の枠部材８１に挿通し、突棒８２を調整孔５０Ａに挿し通して、装着帯４０，５０と中留具１０を連結する。
なお、時計１に予め取り付けられた尾錠８０付のバンド３だけでなく、市販されている尾錠付きのバンドを中留具付きバンドに変える場合にも、前述の方法で変えることができる。このような場合としては、例えば本実施形態の時計１に用いられているバンド３において、古くなった装着帯４０，５０を交換する場合であり、中留具１０をそのまま流用するとともに、装着帯や尾錠として市販の新たなバンドのものを用いればよい。
【００２３】
図２において、本実施形態に係わる時計１は、ムーブメントが収容されたケース２を備え、このケース２には、ケース本体２Ａを挟んで２対のバンド取付部２Ｂが形成されており、装着帯４０，５０の端部が、それぞれ一対のバンド取付部２Ｂの間に挿入され、これらの装着帯４０，５０の端部に設けられた孔部４０Ｃ，５０Ｃに、ばね棒６１を挿入して着脱自在で、かつ回動可能に取り付けられている。このばね棒６１は、前述したばね棒６０と同じ構成とされている。
装着帯４０のもう一方の端部４０Ｂは、中留具１０の下板部材２０に形成された一対のバンド取付部２０Ｂの間に挿入されてばね棒６０で着脱自在、かつ回動可能に取り付けられている。装着帯４０の中留具１０側には、バンド止め輪４１，４２が設けられていており、一方のバンド止め輪４１が装着帯４０に固着され、バンド止め輪４２がバンド止め輪４１よりケース２側に配置されて、装着帯４０の長手方向に移動可能とされている。
装着帯５０の他方の端部５０Ｂは、尾錠８０の一対のアーム部８１Ａの間に下板部材２０側から挿通され、突棒８２の先端部８２Ｂが、適宜選択された調整孔５０Ａに挿し通されて係止され、端部がバンド止め輪４１，４２に挿通されている。このことによって、時計１は、ケース２、装着帯４０，５０、中留具１０が連結されて、腕に装着することができる。
【００２４】
従って、本実施形態によれば、次のような効果が得られる。
（１）中留具１０によれば、下板部材２０および中板部材３０の端部に設けられたバンド取付部２０Ｂおよび尾錠取付部３０Ｆに対しては、予め時計１に用いられていたバンド３の装着帯４０，５０および尾錠８０をそのまま取り付けることができるため、バンド３の着脱を容易にするためには、単なる尾錠８０付きのバンド３に中留具１０を組み入れるだけでよい。従って、既設のバンド３に用いられている装着帯４０，５０および尾錠８０をそのまま流用でき、尾錠８０付きのバンド３が本来保有する意匠性を確実に維持できる。つまり、中留具１０単体、または予め中留具１０が付いたバンド３、あるいはこのような中留具１０付きのバンド３が用いられた時計１を一度購入してしまえば、その後のバンド交換においては、尾錠付きバンドの特有の外観を維持しつつ、着脱し易い時計を得ることができる。
【００２５】
（２）また、装着帯４０，５０等が老朽化し、新たな別の市販バンドと交換するときでも、中留具１０をそのまま残して装着帯および尾錠だけを交換すればよく、市販されている尾錠付きバンドが本来有する意匠性を確実に維持できる。また、中留具１０を残したまま尾錠および装着帯のみを交換することができることから、新たな中留具が付いたバンドを丸ごと新規に購入して交換する必要がなく、交換に要する費用を安価にすることもできる。
【００２６】
（３）さらに、装着帯４０，５０および尾錠８０は任意に選択でき、中留具１０との組み合わせも任意であるから、市場での多様なデザインや素材のバンド３を購入して組み合わせることができ、使用者の選択幅を大幅に拡大でききる。
【００２７】
（４）中留具１０にはプッシュ中留機構９０が設けられ、このプッシュ中留機構９０のプッシュボタン９２を操作するだけで下板部材２０および中板部材３０互いの係合状態を解除することができ、バンド３の着脱を一層容易にできる。
【００２８】
（５）この際、プッシュ中留機構９０では、係止片９２Ａが下板部材２０に設けられ、これに係止する係止軸３１が中板部材３０に設けられ、下板部材２０および中板部材３０が直に係合する構造であるから、背景技術で説明した特許文献２，３に記載の上箱や上板部材を不要にでき、構造を簡略化できる。
【００２９】
〔第２実施形態〕
次に、本発明の第２実施形態に係わる中留具について説明する。本実施形態の中留具は、第１実施形態とは、装着帯４０および尾錠８０との取付部のみが異なるものであるから、以下に取付部を中心に説明し、その他の構造については説明を省略する。
【００３０】
図３は、本実施形態の中留具１００の半開きの状態を示す斜視図を示す。
図３において、中留具１００を構成する下板本体２００Ａには、長手方向途中から一方の端部にかけて一対のアーム部２００Ｂが形成され、その端部には下板本体２００Ａの上面２００Ｃ側に略円筒状に丸められた略筒状の尾錠取付部（第２取付部）２００Ｄが形成されている。尾錠８０の一対のアーム部８１Ａの間に一対の尾錠取付部２００Ｄが挿入され、尾錠８０の突棒基部８２Ａが尾錠取付部２００Ｄの中央部に挿入され、各部材に穿設された孔を貫通してばね棒６０が挿入され、尾錠８０が下板部材２００に着脱可能に取り付けられている。尾錠８０の取付部構造は、前述した第１実形態（図１）の尾錠８０と中板部材３０との取り付け構造と同じである。ここで、尾錠８０は、下板本体２００Ａとは反対方向に向けて装着されている。
下板本体２００Ａの他方の端部側は、長手方向途中から端部に向かって平面方向幅が徐々に狭く形成され、その先端に下板本体２００Ａの上面２００Ｃ側に、略円筒状に丸められた連結部２００Ｅが形成されている。下板本体２００Ａの尾錠８０装着側には、プッシュ中留機構９０が装着されている。プッシュ中留機構９０の構造は第１実施形態（図１）と同じのため説明は省略するが、プッシュボタン９２の押し操作および操作解除で、プッシュ中留機構９０と中板部材３００に設けられている係止軸３１との係脱ができ、中板部材３００の折り畳み係止と展開が行われる。
【００３１】
中板本体３００Ａの長手方向の一方の端部には、当該中板本体３００Ａの幅方向両側に突出した一対のバンド取付部（第１取付部）３００Ｂが形成されている。バンド取付部３００Ｂの先端はそれぞれ、中板本体３００Ａの上面３００Ｃ側に折り曲げられており、その先端には、ばね棒６０のピン挿通孔３００Ｆが穿設されている。バンド取付部３００Ｂとは反対側には、長手方向途中から一対のアーム部３００Ｅが端部まで形成され、その先端部には中板本体３００Ａの上面３００Ｃ側に略円筒状に丸められた連結部３００Ｄが形成されている。
この中板部材３００と下板部材２００との連結部構造は第１実施例（図１）と同じため説明は省略するが、中板部材３００と下板部材２００とは、折り畳み可能に中板固定軸７０が挿通され連結されている。
ここで、中板部材３００の一対のバンド取付部３００Ｂの間には、装着帯４０の端部４０Ｂが配置され、ばね棒６０によって着脱自在に取り付けられている。また、装着帯５０の端部５０Ｂは、尾錠８０に挿通され、突棒８２の先端部８２Ｂを調整孔５０Ａに挿し通して係止されている。
また、中板本体３００Ａの長手方向途中には、中板部材３００を折りたたんだ際に、プッシュボタン９２の係止片９２Ａと係合する位置にプッシュ中留機構９０に向かって係止軸３１が軸止されている。これら、プッシュ中留機構９０および係止軸３１の係脱構造も第１実形態（図１）と同じである。
【００３２】
このような第２実施形態の中留具１００は、前述した第１実施形態の中留具１０とは、装着帯４０，５０および尾錠８０が、中板部材３０，３００または下板部材２０，２００のどちらに装着されるかという違いがあるものの、任意の装着帯４０および尾錠８０が中留具１０に着脱自在に取り付けられるという構造や、他の構造は同じであるため、前述した（１）〜（５）の効果を同様に得ることができる。
【００３３】
次に、本発明の第３実施形態に係わる中留具について説明する。本実施形態の中留具は、第１実施形態、第２実施形態による中留具に対して観音開き式中留具と呼ばれ、下板部材両端に一対の中板部材が折り畳み自在に連結されている。
【００３４】
図４は、本発明の中留具１０００を半開きにした状態を示す断面図である。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a clasp, a band, and an accessory.
[0002]
[Background Art]
Conventionally, in a jewelry or watch, as a fastener such as a leather band or a urethane band configured with a pair of wearing bands, a frame member through which the band is inserted, and a protrusion inserted through an adjustment hole provided in the band. A buckle with a stick is often used. The buckle may have a simple structure, and various designs are provided. However, there has been a problem that the periphery of the adjustment hole where the band is repeatedly attached and detached is easily damaged, and the band is difficult to attach and detach as compared with the clasp used for the metal band.
[0003]
For this reason, it has been proposed to use a clasp as a stopper for an accessory, a leather band of a watch, a urethane band, or the like.
For example, a two-folded middle plate member and a lower plate member each having one end connected to each other are used, an upper box member is connected to the middle plate member, and one mounting band having an adjustment hole is connected to an end of the lower plate member. It is known that a middle clasp that inserted the support pin attached to the lower part, inserted the locking pin on the lower side of the lower plate member into the adjustment hole and locked it, and attached the other mounting band to the upper box. (For example, Patent Document 1).
In addition, a push-type operation unit is provided on the upper box, a two-piece clasp is connected to this upper box, and a locking pin that engages and disengages with the opening / closing hole of the operation unit is provided on the lower plate member, and adjustment is performed. One of the mounting bands having holes is inserted into the through hole formed at the end of the lower plate member, and a locking pin is inserted into the adjustment hole on the lower surface side of the lower plate member and locked, and the other mounting band is A clasp attached to an upper box is known (for example, Patent Document 2).
Also, a lower plate member and a middle plate member having one end connected to each other are provided, and a buckle is connected to an upper plate member provided at the other end of the middle plate member, and the other mounting band is locked by the buckle. Fasteners are also known. In addition, this clasp has an operation part provided on the upper plate member, and there is also a double door type provided with a pair of middle plate members (for example, Patent Document 3).

[Problems to be solved by the invention]
In such a clasp of Patent Literature 1 or Patent Literature 2, a bifolded lower plate member and a middle plate member are connected to an upper box member, and a mounting band having an adjustment hole is provided at an end of the lower plate member. A buckle used for a leather band, a urethane band, or the like as a clasp because it has a structure that is inserted through the support frame or through-hole toward the lower surface of the lower plate member and is locked by a stopper pin. It cannot be used and does not have the same appearance as a band with a buckle. In addition, when worn on the arm, the wearing band is on the lower surface side of the lower plate member, and the upper box member is arranged on the outermost side with respect to the arm, so in this respect, the same appearance as the band with buckle is obtained. Absent.
On the other hand, in the middle clasp of Patent Document 3, the attachment band is inserted into the buckle attached to the upper box member, and the attachment band is locked, so that it is equivalent to a band with a general buckle. Appearance is obtained.
However, with regard to the buckle, the protruding bar and the frame member constituting the buckle are specially designed for the buckle, so that a commonly used buckle cannot be attached. Therefore, when such a clasp is used, there are the following problems.
That is, first, when the band with the simple buckle is changed to the clasp to facilitate the detachability of the band, the buckle used for the existing band cannot be used as it is, The design is impaired. That is, since the entire band is usually designed by total coordination of the wearing band and the buckle, if the original buckle cannot be used, an imbalance occurs in design.
Secondly, when the band with the clasp is already used, and the wearing band is deteriorated, the entire band with the clasp needs to be replaced. It is not possible to purchase a band with a buckle that is widely marketed and replace only the buckle and the wearing band while leaving the clasp. Therefore, the cost required for replacement is uneconomical. Of course, it is also possible to purchase a band with a clasp and replace only the wearing band, but in such a case, the first problem occurs.
[0006]
An object of the present invention is to provide a clasp, a band, and an accessory that can reliably maintain the original design of the band with a buckle and that can be replaced at low cost.
[0007]

The other end of the other one of the middle plate member and the lower plate member is provided with a second attachment portion to which an arbitrarily selected buckle is detachably attached. The second end portion is locked. Here, as the band, a band formed of a flexible material such as a leather band or a urethane band can be adopted.
In addition, “arbitrarily selected wearing band” and “arbitrarily selected buckle” refer to, for example, a commercially available band, a wearing band and a buckle of a band originally attached to accessories.
[0008]
According to the present invention, the first and second attachment portions to which the arbitrarily selected attachment band and the buckle are detachably attached are provided at the ends of the middle plate member and the lower plate member constituting the clasp. Therefore, for example, when changing a band with a simple buckle to a clasp to facilitate the attachment and detachment of the band, the wearing band and the buckle used for the existing band are diverted as they are. That is, the design inherent in the band with the buckle can be reliably maintained.
In addition, when the wearing band is deteriorated, a commercially available band with a buckle can be purchased, and only the buckle and the wearing band can be replaced while leaving the middle clasp. There is no need to purchase and replace the entire band with, and the cost required for replacement is reduced.
[0009]
The clasp of the present invention is a clasp for connecting a first end portion and a second end portion of a mounting band used for a personal accessory, and includes a pair of middle plate members, and one end of each of the middle plate members at both ends.

Further, the tip of the other mounting band 50 is inserted into the frame member 81 of the buckle 80, and the protruding rod 82 is inserted through the adjustment hole 50A to connect the mounting bands 40 and 50 to the clasp 10.
It should be noted that not only the band 3 with the buckle 80 previously attached to the watch 1 but also a commercially available band with the buckle can be changed to the band with the clasp in the above-described manner. Such a case is, for example, a case where old wearing bands 40 and 50 are replaced in the band 3 used in the timepiece 1 of the present embodiment. A commercially available new band may be used as the buckle.
[0023]
In FIG. 2, a timepiece 1 according to the present embodiment includes a case 2 in which a movement is housed, and the case 2 has two pairs of band mounting portions 2B sandwiching a case body 2A. The ends of the bands 40 and 50 are inserted between the pair of band mounting portions 2B, and the spring bars 61 are inserted into and removed from the holes 40C and 50C provided at the ends of the mounting bands 40 and 50, respectively. It is freely and rotatably mounted. The spring bar 61 has the same configuration as the spring bar 60 described above.
The other end 40 B of the mounting band 40 is inserted between a pair of band mounting portions 20 B formed on the lower plate member 20 of the clasp 10, and is detachably and rotatably mounted by a spring bar 60. Have been. Band retaining rings 41 and 42 are provided on the clasp 10 side of the mounting band 40, and one band retaining ring 41 is fixed to the mounting band 40, and the band retaining ring 42 is connected to the case by the band retaining ring 41. It is arranged on two sides and is movable in the longitudinal direction of the mounting band 40.
The other end 50B of the mounting band 50 is inserted between the pair of arms 81A of the buckle 80 from the lower plate member 20 side, and the distal end 82B of the protruding rod 82 is inserted into the appropriately selected adjustment hole 50A. And the ends are inserted through the band retaining rings 41 and 42. As a result, the timepiece 1 can be mounted on the wrist with the case 2, the mounting bands 40 and 50, and the clasp 10 connected thereto.
[0024]
Therefore, according to the present embodiment, the following effects can be obtained.
(1) According to the clasp 10, a band previously used for the timepiece 1 is used for the band attaching portion 20 B and the buckle attaching portion 30 F provided at the ends of the lower plate member 20 and the middle plate member 30. Since the mounting bands 40 and 50 and the buckle 80 of the third buckle 3 can be attached as they are, in order to easily attach and detach the band 3, the clasp 10 may be simply incorporated into the band 3 with the buckle 80. Therefore, the mounting bands 40 and 50 and the buckle 80 used for the existing band 3 can be diverted as they are, and the design inherent in the band 3 with the buckle 80 can be reliably maintained. In other words, once the clasp 10 alone, the band 3 with the clasp 10 in advance, or the watch 1 using such a band 3 with the clasp 10 is purchased, the band is replaced thereafter. In this case, it is possible to obtain a watch that can be easily attached and detached while maintaining the unique appearance of the band with the buckle.
[0025]
