Description

【０００１】
【発明の属する技術分野】
本発明は二つの中留を有する時計バンドの中留構造に関する。
【０００２】
【従来の技術】
従来技術における時計バンドの中留構造においては、実開昭５３−１２７５７２に示すようなものがある。これについて、図１０を用いて説明する。
【０００３】
受板８１の略中央付近に係止片８７、８８を対設させ、受板８１の左右両方向に、連結ピン９２、９３を介して中板８３、８４を回動可能に連結する。そして、中板８３、８４の他端に連結ピン９４、９５を介して表カバー８５、８６を回動可能に連結する。
【０００４】
そして、受板８１上に取り付けられた連結ピン９２から係止片８７までの長さと、中板８３の連結ピン９２から連結ピン９４までの長さとは略同じ長さで、表カバー８５を閉じた状態では、受板８１に設けた係止片８７が連結ピン９４を内包した連結部の外周部に弾性をもって圧接している。
【０００５】
また、受板８１上に取り付けられた連結部９３から係止片８８までの長さと、中板８４の連結ピンから連結ピンまでの長さも略同じ長さで、表カバー８６を閉じた状態では、受板８１に設けた係止片８８が連結ピン９５を内包した連結部の外周部に弾性をもって圧接している。
【０００６】
そして、表カバーを開くときは、表カバー８５の側面を持って係止片８７と連結ピン９４の外周部との係合を解除することにより、中板８３を介して受板８１と表カバー８５とが離れ、表カバー８５が開かれる。
【０００７】
また、表カバー８６の場合も同様に、表カバー８６の側面を持って係止片８８と連結ピン９５を内包した連結部の外周部との係合を解除することにより、中板８４を介して受板８１と表カバー８６とが離れ、表カバー８６が開かれる。
【０００８】
【発明が解決しようとする課題】
この前述の時計バンドの中留構造では、受板の長さが長いため、多少湾曲していても、腕に沿うように装着するのは困難であり、特に腕の細い人では受板の端部が突っ張ってしまい、装着感が悪くまた外観も芳しくなかった。
【０００９】
本発明の目的は上記課題を解決して、中留部がより腕に沿うようにして、装着感が向上し、なおかつ外観もさらに良くなり、更に、中留の開放時の操作性を向上ようにすることが可能な時計バンドの中留構造を提供することにある。
【００１０】
【課題を解決するための手段】
上記課題を解決するため、本発明の時計バンドの中留構造では、第１の受板と、その一端に連結される中板と、前記中板に連結される第１のバンド連結部材とを有し、それぞれを連結ピンによって連結し三折れとし、また、第２の受板と、その一端に連結される中板と、該中板に連結される第２のバンド連結部材とを有し、それぞれ連結ピンによって連結し三折れとして、第２の中留を構成し、少なくとも、前記第１の受板と前記第１のバンド連結部材とを係止するための係止機構を有していて、前記第１の受板と前記第２の受板との端部を連結ピンを介して回動可能に連結したことで、装着時に第１の中留、第２の中留が腕に接触することを特徴とする。
【００１１】
また、前記第１のバンド連結部材と前記第２のバンド連結部材の一部に、各々対向する第１のバンド連結部材と第２のバンド連結部材とが干渉しないようにして、引掛け部が設けられていることを特徴とする。
【００１２】
また、前記係止機構が、前記第１の受板に設けた係止片を、前記第１のバンド連結部材と中板とを連結している連結ピンを内包した連結部の外周部に、係脱自在に係止する構造で、第２のバンド連結部材の上面を覆うように、第１のバンド連結部材に引掛け部を設けたことを特徴とする。
【００１３】
また、前記第２のバンド連結部材に設けた突起の上面が、第１のバンド連結部材の引掛け部の下面と常に接するように配置され、前記第１および第２の中留が回転したときに、前記突起の上面と前記引掛け部の下面とが接しながら回転し、前記第２の中留が閉じた状態で維持されることを特徴とする。
【００１４】
また、前記係止機構が、少なくとも前記第１の受板に設けた係止片を、前記第１のバンド連結部材と中板とを連結している連結ピンを内包した連結部の外周部に、係脱自在に係止する構造で、第２のバンド連結部材に設けた引掛け部の上面を覆うロックカバーを第１のバンド連結部材に取り付けたことを特徴とする。
【００１５】
また、前記ロックカバーが閉じた状態で、前記第２のバンド連結部材に設けた引掛け部の上面が、ロックカバーの下面と常に接するように配置され、前記第１および第２の中留が回転したときに、前記第２の中留が閉じた状態で維持されることを特徴とする。
さらに、前記係止機構が、少なくとも第１の受板または第１のバンド連結部材に係止片を設け、第１のバンド連結部材または第１の受板に、係止片と係合しプッシュ操作することによって係合を操作する機構であることを特徴とする。
【００１６】
【発明の実施の形態】
以下図面を用いて本発明の時計バンドの中留構造の最適な実施形態を説明する。
【００１７】
〔第１の実施形態：図１、図２、図３〕
本発明の第１の実施形態における時計バンドの中留構造について図１と図２と図３とを用いて説明する。
【００１８】
図１は本発明の第１の実施形態における時計バンドの中留構造の中留の係合を解除したときの側面図である。
図２は本発明の第１の実施形態における時計バンドの中留構造の中留を係合したときの側面図である。
図３は本発明の実施形態における時計バンドの中留構造の上面図である。
【００１９】
まず、第１の中留１０１と第２の中留１０２の各部品およびそれらの構成について述べる。ここで、本実施形態では、中留とバンドとを直接連結しているバンド連結部材を表カバーと呼ぶ。
【００２０】
まず、第１の中留１０１では、第１の受板１と、中板３、および、第１の表カバー５とをそれぞれ連結ピンによって連結し三折れとしている。
【００２１】
詳しくは、第１の受板１の一端に連結ピン１２を介して中板３が回動自在に取り付けられていて、それと反対側の端面付近に係止片７が備えられている。また、中板３の他端には連結ピン１４を介して第１の表カバー５が回動自在に取り付けられている。そして、第１の表カバー５の先端には引掛け部９が備えられていて、その反対側に時計バンドが連結されている。
【００２２】
同様に、第２の中留１０２では、第２の受板２と、中板４、および、第２の表カバー６ともそれぞれ連結ピンによって連結し三折れとしている。
【００２３】
詳しくは、第２の受板２の一端に連結ピン１３を介して中板４が回動自在に取り付けられていて、それと反対側の端面付近に係止片８が備えられている。また、中板４の他端には連結ピン１５を介して第２の表カバー６が回動自在に取り付けられている。そして、第２の表カバー６の先端にも引掛け部１０が備えられていて、その反対側に時計バンドが連結されている。
【００２４】
そして、第１の受板１と第２の受板２の、中板３、４と連結している端部とは反対側の端部を連結ピン１１を介して回動自在に連結し、第１の中留１０１と第２の中留１０２とが可動可能に連結される。
【００２５】
また、本実施形態では図３に示すように、第１の表カバー５と第２の表カバー６の対向する端部に引掛け部９、１０が備えられ、表カバーを閉じたときに各々が干渉しないように配置されている。
また、引掛け部９、１０は指を引掛けやすいように表カバーから突出している。
【００２６】
次に、表カバーの係止機構について説明する。
【００２７】
第１の中留１０１では、第１の表カバー５内に、第１の受板１と中板３が折り畳まれ、係止片によって固定されている。
【００２８】
詳しくは、第１の受板１上に取り付けられた連結ピン１２から係止片７までの長さと、中板３の連結ピン１２から連結ピン１４までの長さとは略同じ長さで、第１の表カバー５を閉じた状態では、第１の受板１に設けた係止片７が連結ピン１４を内包した連結部の外周部に弾性をもって圧接し、第１の表カバー５を固定している。
【００２９】
第２の中留１０２でも同様に、第２の表カバー６内に第２の受板２と中板４が折り畳まれ、係止片によって固定されている。
【００３０】
詳しくは、第２の受板２上に取り付けられた連結ピン１３から係止片８までの長さと、中板４の連結ピン１３から連結ピン１５までの長さが略同じ長さで、表カバー６を閉じた状態では、第２の受板２に設けた係止片８が連結ピン１５を内包した連結部の外周部に弾性をもって圧接し、第２の表カバー６を固定している。
【００３１】
このようにして表カバーが係止され、表カバーを閉じた状態で二つの中留が回動自在に可動する。
【００３２】
次に、表カバーを開く操作について説明する。
【００３３】
表カバーを開くときは、図２に示すように、第１の中留め１０１の引掛け部９とそれに対向する第２の表カバー６の間を多少離間させるように、第１の中留１０１と第２の中留１０２とを閉じた状態で回転させる。これによって指が入れやすくなる。そして、指の腹もしくは爪で、引掛け部９を引掛けて上方に持ち上げ、第１の受板１に設けた係止片７と連結ピン１４を内包した連結部の外周部との係合を解除して表カバーを開く。
第２の中留め１０２についても同様であるので説明を省略する。
【００３４】
このように、本実施形態では二つの中留１０１、１０２が回転可能に連結されているので、各々の表カバーを開くときに操作性が向上し、また、装着時には腕に沿うようになり装着感が向上する。
【００３５】
〔第２の実施形態：図４、図５〕
本発明の第２の実施形態における時計バンドの中留構造について図４と図５とを用いて説明する。
【００３６】
図４は本発明の第２の実施形態における時計バンドの中留構造の中留を係合したときの側面図である。
図５は本発明の第２の実施形態における時計バンドの中留構造の上面図である。
【００３７】
第１の中留１２１と第２の中留１２２の各部品およびそれらの構成について述べる。本実施形態でも中留とバンドとを直接連結しているバンド連結部材を表カバーと呼ぶ。
【００３８】
まず、第１の中留１２１では、第１の実施形態と同様、第１の受板２１と、中板２３、および、第１の表カバー２５とをそれぞれ連結ピンによって連結し三折れとしている。
【００３９】
詳しくは、第１の受板２１の一端に連結ピン１２を介して中板２３が回動自在に取り付けられていて、それと反対側の端面付近に係止片２７が備えられている。また、中板２３の他端には連結ピン３４を介して第１の表カバー２５が回動自在に取り付けられている。また、第１の表カバー２１の先端には引掛け部２９が備えられていて、その反対側に時計バンドが連結されている。
【００４０】
第２の中留１２２では、第１の実施形態と異なり、係止片が備えられいない（ただし、本実施形態では、係止片が存在しないが、係止片を備えていても良い）。その他は同様で、第２の受板２２と、中板２４、および、第２の表カバー２６とをそれぞれ連結ピンによって連結し三折れとしている。
【００４１】
詳しく述べると、第１の中留１２１側とは反対側の端面に連結ピン３３を介して第２の受板２２と中板２４とが回動自在に取り付けられている。また、中板２４の他端には連結ピン３５を介して第２の表カバー２６が回動自在に取り付けられている。また、第２の表カバー２６の先端には突起３０が備えられていて、その反対側に時計バンドが連結されている。ここでは突起３０を設けた構造とするが、第２の表カバー２６の先端を突起の代用としても良い。
【００４２】
第２の中留には係止片が存在しないため、各部品を折り畳むときにその状態を保つ手段は設けられていない。
【００４３】
そして、第１の受板２１、第２の受板２２の、中板と連結している端部とは反対側の端部を、連結ピン３１を介して回動自在に連結し、第１の中留１２１と第２の中留１２２とが可動可能に連結される。
【００４４】
また、第１の表カバー２５には引掛け部２９が、第２の表カバー２６には突起３０がそれぞれ設けられていて、引掛け部２９は突起３０の上側を覆うように位置する。
【００４５】
次に、表カバーの係止機構について説明する。
【００４６】
第１の中留１２１では、第１の表カバー２５内に、第１の受板２１と中板２３が折り畳まれ、係止片によって固定されている。
【００４７】
詳しくは、第１の受板２１上に取り付けられた連結ピン３２から係止片２７までの長さと、中板２３の連結ピン３２から、第１の表カバー２５に位置する連結ピン３４までの長さとは略同じ長さで、第１の表カバー２５を閉じた状態では、第１の受板２１に設けた係止片２７が、連結ピン３４を内包した連結部の外周部に、弾性をもって圧接し、表カバーを固定している。
【００４８】
第２の中留１２２では、第２の表カバー２６内に、第２の受板２２と中板２４が折り畳まれる。このとき特に、中留を閉じたときに第２の受板２２と中板２４と第２の表カバー２６とを固定する部材は設けられていない。
【００４９】
ここで、第２の中留１２２の固定方法を説明する。
突起３０の上面が引掛け部２９の下面と接するように位置し、第２の中留１２２が回転したときに、ある範囲までは突起３０の上面と引掛け部２９の下面とが接しながら回転し、そのとき第２の中留１２２は閉じた状態で維持される。そしてそれを越えると、突起３０の上面が引掛け部２９の下面と当接しそれ以上回転しなくなる。
【００５０】
これにより、特に第２の受板２２と中板２４と第２の表カバー２６とを固定する部材を設けなくとも、第１の表カバー２５の引掛け部が第２の表カバー２６の開放を規制しているため、第２の中留１２２が外れることなく固定される。
【００５１】
次に表カバーを開く操作について説明する。
表カバーを開くときは、第１の表カバー２５に設けた引掛け部２９を引っ張って係止片２７と連結ピン３４を内包した連結部の外周部との係合を解除して開く。このとき第２の表カバー２６は第１の表カバー２５に設けた引掛け部２９によって開放が規制されていたため、第１の表カバー２５が開かれると第２の表カバー２６の規制がとれて、第２の表カバー２６が開かれる。
【００５２】
このとき、第１の中留１２１と第２の中留１２２とが可動するのを利用して、引掛け部２９の先端とその下に位置する第２の表カバー２６との間を広くすることにより係合解除を容易にすることが出来る。
【００５３】
このように、本実施形態でも二つの中留１２１、１２２が回転可能に連結されているので、表カバーに設けた引掛け部を指で引掛けやすくでき、また、第１の表カバー２５を開放すると、第２の表カバー２６も同時に開放されるため、更に操作性が向上する。
【００５４】
〔第３の実施形態：図６、図７〕
本発明の第３の実施形態における時計バンドの中留構造について図６と図７を用いて説明する。
【００５５】
図６は本発明の第３の実施形態における時計バンドの中留構造の中留を係合したときの側面図である。
図７は本発明の第３の実施形態における時計バンドの中留構造の上面図である。
【００５６】
本実施形態と第１の実施形態とは類似していて、違いは、第１の表カバーの、引掛け部の上にさらにロックカバーを設けたことである。
【００５７】
ここでは、同一内容の説明を省略し、ロックカバー４９の構成について説明する。
【００５８】
第１の表カバー４５の第２の表カバー４６と対向する面に、連結ピン５４を介して、ロックカバー４９が回動可能に取り付けられている。そして、ロックカバー４９は第２の表カバー４６の、第１の表カバー４５と対向する先端とそこに設けた引掛け部５０を覆うように位置し、ロックカバー４９に設けたロック係合凸部５７と、それに対向した第１の表カバー４５に設けた穴とを凹凸嵌合することによって、ロックカバー４９が回転しないようにして第１の表カバー４５に固定される。
中留の開閉は、ロックカバー４９を開いた後は第１の実施形態と同様である。
【００５９】
なお、ロックカバー４９を閉じた状態のときに、ロックカバー４９に第２の実施形態の引掛け部と同じ機能をもたせ、その代わりとして代用することも可能である。このとき、第２の表カバー４６に設けた、引掛け部５０の上面が第１の表カバー４５に設けたロックカバー４９の下面と接するように位置し、中留が回転したときに、引掛け部５０の上面とロックカバー４９の下面とが接しながら回転し、特に係止機構を設けなくとも第２の表カバー４６は閉じた状態で維持されるという類似の効果が期待できる。
【００６０】
このようにロックカバーを取り付けることにより引掛け部がロックカバーの下側に隠れるため、ふいの事故によって引掛け部を引掛けて中留を外してしまうのを防ぐことができる。
また、ロックカバーを引掛け部として使用することもでき、外観と操作性が更に良くなる。
【００６１】
以上述べてきたような実施形態によって、本発明が達成されるが、更に、例えば図８、図９のように、表カバーと受板とを係合する係止機構が、係止片と連結ピンとを圧接する代わりに、受板または表カバーに係止片を設け、それに対向する表カバーまたは受板にプッシュボタン操作部を設けて、プッシュボタンを介して係止片を係合し、プッシュ操作することによって係合を操作する、プッシュボタン付き中留機構であっても良い。
【００６２】
また、表カバーは必ずしもカバーである必要はなく中板とバンドの間をつなぐバンド連結部材であればよい。
【００６３】
【発明の効果】
以上の説明から明らかなように、本発明では第１の受板と第２の受板とが連結ピンによって可動するように連結されているため、第１の中留と第２の中留が回動自在に配置され、中留部がより腕に沿うようになり装着感が向上し、外観も向上する。また、中留の係合を操作するときも、中留間により大きな空間ができ、表カバーの端部に指を引掛けやすくなり、開閉の操作性が向上するという効果がある。
【００６４】
また、第１のバンド連結部材と第２のバンド連結部材同士が干渉しないようにして、引掛け部が設けられているためスムーズにバンド連結部材の開放が行える。
【００６５】
第２のバンド連結部材の上面を覆うように、第１のバンド連結部材に引掛け部を設けた場合は、第１の中留と第２の中留めとを回転させたとき、第１のバンド連結部材に設けた引掛け部と第２のバンド連結部材間に更に大きな隙間ができ、指で引掛けやすくなるという効果がある。
【００６６】
また、第２のバンド連結部材に設けた突起の上面が、第１のバンド連結部材の引掛け部の下面と常に接するように配置され、第１および第２の中留が回転したときに、突起の上面と引掛け部の下面とが接しながら回転し、第２の中留が閉じた状態で維持される構造では、特に第２の中留を折り畳んで固定する手段を設けなくてもよく、中留の開閉がよりスムーズに行えるとともに、部品点数が少なくなり、同時に加工工程も少なくなるという効果がある。
【００６７】
第２のバンド連結部材に設けた引掛け部の上面を覆うロックカバーを第１のバンド連結部材に取り付けた構造では、ロックカバーによって、ふいの事故によって引掛け部が引掛かって中留が開いて腕時計が外れるのを防止できるという効果がある。
【００６８】
またロックカバーを閉じた状態にして、先に述べた、第２のバンド連結部材の上面を覆うように第１のバンド連結部材に設けた引掛け部と同じ効果を発生させることもできる。
【００６９】
更に、第１のバンド連結部材または第１の受板に、係止片と係合しプッシュ操作することによって係合を操作する機構を設けることにより。中留の固定を強固なものにするという効果も期待できる。

Then, the second front cover 26 is opened.
[0052]
At this time, by utilizing the movement of the first middle end 121 and the second middle end 122, the space between the front end of the hook portion 29 and the second front cover 26 located therebelow is widened. The engagement can be easily released.
[0053]
Thus, since the two middle ends 121 and 122 are rotatably connected in this embodiment, the hook portion provided on the front cover can be easily hooked with a finger, and the first front cover 25 is When opened, the second front cover 26 is also opened at the same time, so that the operability is further improved.
[0054]
[Third Embodiment: FIGS. 6 and 7]
An intermediate structure of the watch band according to the third embodiment of the present invention will be described with reference to FIGS.
[0055]
FIG. 6 is a side view of the watch band in the middle structure of the third embodiment of the present invention when engaged.
FIG. 7 is a top view of a watch band retaining structure according to the third embodiment of the present invention.
[0056]
This embodiment is similar to the first embodiment, and the difference is that a lock cover is further provided on the hook portion of the first front cover.
[0057]
Here, the description of the same content is omitted, and the configuration of the lock cover 49 will be described.
[0058]
A lock cover 49 is rotatably attached to a surface of the first front cover 45 facing the second front cover 46 via a connecting pin 54. The lock cover 49 is positioned so as to cover the tip of the second front cover 46 facing the first front cover 45 and the hooking portion 50 provided there. The lock cover 49 is fixed to the first front cover 45 so as not to rotate by engaging the portion 57 with a hole provided in the first front cover 45 opposed thereto.
The opening and closing of the middle end is the same as that of the first embodiment after the lock cover 49 is opened.
[0059]
In addition, when the lock cover 49 is in a closed state, the lock cover 49 can have the same function as the hook portion of the second embodiment, and can be used instead. At this time, the hook 50 provided on the second front cover 46 is positioned so that the upper surface of the hook portion 50 is in contact with the lower surface of the lock cover 49 provided on the first front cover 45, and the hook is rotated. A similar effect can be expected in which the upper surface of the hook portion 50 and the lower surface of the lock cover 49 rotate while in contact with each other, and the second front cover 46 is maintained in a closed state without any particular locking mechanism.
[0060]
By attaching the lock cover in this manner, the hook portion is hidden under the lock cover, so that it is possible to prevent the hook from being hooked and removing the middle retainer due to a blockage accident.
Also, the lock cover can be used as a hooking portion, and the appearance and operability are further improved.
[0061]
The present invention is achieved by the embodiments described above. Further, as shown in FIGS. 8 and 9, for example, a locking mechanism for engaging the front cover and the receiving plate is connected to the locking piece. Instead of press-contacting the pin, a locking piece is provided on the receiving plate or the front cover, a push button operation part is provided on the front cover or receiving plate facing it, and the locking piece is engaged via the push button. It may be an intermediate mechanism with a push button that operates the engagement by operating.
[0062]
Further, the front cover is not necessarily a cover, and may be a band connecting member that connects between the middle plate and the band.
[0063]
【The invention's effect】
As is apparent from the above description, in the present invention, since the first receiving plate and the second receiving plate are connected so as to be movable by the connecting pin, the first middle stop and the second middle stop are provided. It is arranged so that it can rotate freely, and the middle part is more along the arm, so that the feeling of wearing is improved and the appearance is also improved. In addition, when operating the engagement of the middle ends, a larger space is created between the intermediate ends, and it becomes easier to hook a finger on the end portion of the front cover, thereby improving the opening / closing operability.
[0064]
Moreover, since the hook part is provided so that the first band connecting member and the second band connecting member do not interfere with each other, the band connecting member can be opened smoothly.
[0065]
When the hook portion is provided on the first band connecting member so as to cover the upper surface of the second band connecting member, when the first middle stopper and the second intermediate stopper are rotated, There is an effect that a larger gap is formed between the hook portion provided on the band connecting member and the second band connecting member, which makes it easy to hook with a finger.
[0066]
In addition, when the upper surface of the protrusion provided on the second band connecting member is always in contact with the lower surface of the hook portion of the first band connecting member, and when the first and second middle ends rotate, In the structure in which the upper surface of the protrusion and the lower surface of the hook portion rotate while contacting each other and the second middle end is maintained in a closed state, it is not particularly necessary to provide means for folding and fixing the second intermediate end. In addition, the middle end can be opened and closed more smoothly, the number of parts is reduced, and the number of processing steps is reduced.
[0067]
In the structure in which the lock cover that covers the upper surface of the hook portion provided on the second band connecting member is attached to the first band connecting member, the hook portion is hooked by the accident of the lid and the middle ring is opened by the lock cover. This has the effect of preventing the wristwatch from coming off.
[0068]
Further, the same effect as that of the hooking portion provided on the first band connecting member so as to cover the upper surface of the second band connecting member described above can be generated with the lock cover closed.
[0069]
Further, the first band connecting member or the first receiving plate is provided with a mechanism for operating the engagement by engaging with the locking piece and performing a push operation. The effect of strengthening the fixation of Nakadome can also be expected.
