Description

【０００１】
【発明の属する技術分野】
この発明は紙挟みに関し、特に台板に挟持体が設けられ、たとえば書類などを挟持することができる紙挟みに関する。
【０００２】
【従来の技術】
この発明の背景となる従来の紙挟みの一例が、たとえば特許第２６２３２３２号公報に開示されている。図１９はこのような従来の紙挟みの一例を示す斜視図である。図１９に示す紙挟み１は台板２を含む。台板２の端部には、挟持体３が設けられる。挟持体３は、一方側部分３ａがトーションばね（図示せず）で台板２に向けて付勢されている。そのため、台板２と挟持体３の一方側部分３ａとで書類などを挟持することができる。挟持体３の他方側部分３ｂの近傍には、ストッパ部材４が設けられる。ストッパ部材４は、台板２に対して挟持体３の一方側部分３ａがトーションばねの付勢力に抗して開かれた状態で、挟持体３をロックするためのものである。さらに、ストッパ部材４は、それを押圧することによって、挟持体３のロックを解除して挟持体３の一方側部分３ａを閉じるためのものである。
図１９に示す紙挟み１では、挟持体３の他方側部分３ｂを押圧することによって、台板２に対して挟持体３の一方側部分３ａを開くことができ、挟持体３の他方側部分３ｂをさらに押圧することによって、挟持体３の一方側部分３ａを開いた状態で挟持体３をストッパ部材４でロックすることができる。また、図１９に示す紙挟み１では、挟持体３の他方側部分３ｂの近傍にあるストッパ部材４を押圧することによって、挟持体３のロックを解除して挟持体３の一方側部分３ａを閉じることができる。
さらに、この発明の背景となる従来の用箋挟の一例が、たとえば特開２００２−１９３５５号公報に開示されている。図２０はこのような従来の用箋挟の一例を示す斜視図である。図２０に示す用箋挟５でも、台板６の端部に挟持体７が設けられ、挟持体７は一方側部分７ａがトーションばね（図示せず）で台板６に向けて付勢されている。挟持体７の一方側部分７ａの近傍には、台板６に対して挟持体７の一方側部分７ａを開閉するための操作部材８が設けられる。
図２０に示す用箋挟５では、操作部材８を引き上げることによって、台板６に対して挟持体７の一方側部分７ａを開くことができ、操作部材８をさらに引き上げて起こすことによって、挟持体７の一方側部分７ａを開いた状態で挟持体７をロックすることができる。また、図２０に示す用箋挟５では、操作部材８を押圧して倒すことによって、挟持体７のロックを解除して挟持体７の一方側部分７ａを閉じることができる。
図１９に示す紙挟み１および図２０に示す用箋挟５では、それぞれ、台板に対して挟持体を開いた状態で維持することができるので、台板と挟持体との間に書類などを挿入しやすい。
【０００３】
【発明が解決しようとする課題】
ところが、図１９に示す紙挟み１では、台板２に対して挟持体３の一方側部分３ａを閉じる際に、挟持体３において閉じようとする一方側部分３ａとは反対側の他方側部分３ｂの近傍にあるストッパ部材４を押圧しなければならない。そのため、図１９に示す紙挟み１では、ストッパ部材４を押圧して挟持体３の一方側部分３ａを閉じることが分かりにくく、挟持体３を閉じにくい。
また、図２０に示す用箋挟５では、台板６に対して挟持体７の一方側部分７ａを開く際に、操作部材８を引き上げなければならない。そのため、図２０に示す用箋挟５では、挟持体７を開く際に操作部材８が操作しにくく、挟持体７を開けにくい。
【０００４】
それゆえに、この発明の主たる目的は、挟持体を開いた状態で維持することができ、しかも、挟持体を開閉しやすい、紙挟みを提供することである。
【０００５】
【課題を解決するための手段】
この発明にかかる紙挟みは、台板と、台板に固定される基板と、一方側部分が基板に対して開閉できるように中間部分が基板に回動可能に支持される挟持体と、挟持体の一方側部分を基板側に付勢する付勢部材と、挟持体の他方側部分に形成される開用押圧部を有し、開用押圧部を押圧することによって基板に対して挟持体の一方側部分を付勢部材の付勢力に抗して開く開用操作部材と、弾性を有し、基板に対して挟持体の一方側部分を付勢部材の付勢力に抗して開いた状態で開用操作部材に係合する係合部材と、開用押圧部から見て挟持体の一方側部分側に形成される閉用押圧部を有し、閉用押圧部を押圧することによって係合部材を変形して係合部材を開用操作部材から外し、基板に対して挟持体の一方側部分を付勢部材の付勢力で閉じる閉用操作部材とを含む、紙挟みである。
この発明にかかる紙挟みでは、開用操作部材の開用押圧部を押圧することによって、基板に対して挟持体の一方側部分を付勢部材の付勢力に抗して開くことができる。この場合、挟持体において開こうとする一方側部分とは反対側の他方側部分に形成された開用押圧部を押圧すればよいので、開用操作部材が操作しやすく、挟持体を開きやすい。
また、この発明にかかる紙挟みでは、係合部材が、基板に対して挟持体の一方側部分を付勢部材の付勢力に抗して開いた状態で開用操作部材に係合する。そのため、挟持体を開いた状態で維持することができる。
さらに、この発明にかかる紙挟みでは、閉用操作部材の閉用押圧部を押圧することによって、係合部材を変形して係合部材を開用操作部材から外し、基板に対して挟持体の一方側部分を付勢部材の付勢力で閉じることができる。この場合、挟持体において閉じようとする一方側部分側に形成された閉用押圧部を押圧すればよいので、閉用操作部材が操作しやすく、挟持体を閉じやすい。
【０００６】
この発明にかかる紙挟みでは、基板は台板に固定される金属ベースを含み、挟持体は金属の棒からなり、挟持体の中間部分は、金属ベースに回動可能に支持される直線状部分を含み、付勢部材は、一端部分が挟持体の直線状部分に固定され、中間部分が挟持体の直線状部分に巻かれ、他端部分が金属ベースに保持されるコイルばねを含んでもよい。このようにすれば、挟持体および基板を合成樹脂で形成した場合に比べて、挟持体を強固に支持することができる。
【０００７】
また、この発明にかかる紙挟みでは、基板は台板および金属ベース間に固定される樹脂ベースを含み、係合部材は樹脂ベースの一部分で形成されてもよい。このようにすれば、弾性を有する係合部材が形成しやすい。
【０００８】
さらに、この発明にかかる紙挟みでは、閉用操作部材は、閉用押圧部を押圧することによって閉用押圧部とともに回動して係合部材を押圧する押圧片を含み、押圧片が回動する支点から押圧片の先端までの長さを、閉用押圧部が回動する支点から閉用押圧部の先端までの長さより短くしてもよい。このようにすれば、閉用押圧部をより弱い力で押圧することによって、係合部材を変形し、挟持体を閉じることができる。
【０００９】
この発明の上述の目的、その他の目的、特徴および利点は、図面を参照して行う以下の発明の実施の形態の詳細な説明から一層明らかとなろう。
【００１０】
【発明の実施の形態】
図１はこの発明にかかる紙挟みの一例を示す斜視図であり、図２はその紙挟みの要部を示す分解斜視図である。図１に示す紙挟み１０は、たとえば合成樹脂からなる矩形板状の台板１２を含む。台板１２の一端部には、図２に示すように、矩形の切欠部１４が形成される。さらに、台板１２には、切欠部１４の両側に、円形の２つの取付孔１６、１６が間隔を隔てて形成される。
【００１１】
台板１２には、基板として、たとえばステンレスなどの金属からなる金属ベース２０およびたとえばＡＢＳ樹脂などの合成樹脂からなる樹脂ベース８０が固定される。
【００１２】
金属ベース２０は、図３および図４に示すように、長方形板状の主面部分２２を含む。主面部材２２には、円形の２つの取付孔２４、２４が間隔を隔てて形成される。また、主面部材２２の一端側には、断面半円形状の凹み部２６が形成される。さらに、主面部材２２の他端側には、断面Ｃ字状の２つの支持部２８、２８が間隔を隔てて形成される。
【００１３】
金属ベース２０には、図５および図６に示すように、たとえばステンレスなどの金属の棒からなる挟持体３０が支持される。挟持体３０は、図５に示すように、平面的に見て、たとえばコ字状の一方側部分３０ａと、一方側部分３０ａの両端から内側にのびる軸部分となる直線状の２つの中間部分３０ｂ、３０ｂと、中間部分３０ｂ、３０ｂの端部から一方側部分３０ａの反対側にのびる直線状の２つの他方側部分３０ｃ、３０ｃとを含む。また、挟持体３０は、図６に示すように、横から見て、一方側部分３０ａの両側部分が鈍角に折り曲げられるとともに、全体としてＺ字状に見えるように他方側部分３０ｃ、３０ｃが折り曲げられる。
【００１４】
挟持体３０の中間部分３０ｂ、３０ｂは、図５に示すように、たとえばステンレスなどの金属からなる２つのコイルばね３２、３２と、たとえばポリアセタール樹脂などの合成樹脂からなる円筒状の２つのスリーブ３４、３４とに、それぞれ回動可能に通される。この場合、２つのコイルばね３２、３２は、互いに逆巻きに形成される。さらに、挟持体３０の中間部分３０ｂ、３０ｂと、コイルばね３２、３２と、スリーブ３４、３４とは、金属ベース２０の支持部２８、２８にそれぞれ通される。したがって、挟持体３０は、一方側部分３０ａが金属ベース２０の主面部材２２に対して開閉できるように、中間部分３０ｂ、３０ｂが金属ベース２０の支持部２８、２８に回動可能に支持される。
【００１５】
また、コイルばね３２、３２の外側に配置された一端部分は、挟持体３０の中間部分３０ｂ、３０ｂに強固に巻かれて固着される。さらに、コイルばね３２、３２の内側に配置された他端部分は、図６に示すように、支持部２８、２８の隙間に通され、支持部２８、２８で保持される。これらのコイルばね３２、３２によって、挟持体３０の一方側部分３０ａは、金属ベース２０の主面部材２２の凹み部２６に付勢される。この場合、コイルばね３２、３２などが対称に形成されているので、金属ベース２０に対して挟持体３０がひずみにくい。
【００１６】
また、金属ベース２０の支持部２８、２８には、図５に示すように、コイルばね３２、３２とスリーブ３４、３４との間に、２つのかしめ部３６、３６が形成される。これらのかしめ部３６、３６によって、スリーブ３４、３４は、かしめ部３６、３６より外側に変位しないよう規制される。
【００１７】
さらに、挟持体３０の一方側部分３０ａにおいて２つのコーナーの周囲には、図２に示すように、たとえばポリプロピレンなどの合成樹脂からなる２つの紙押さえ３８、３８が形成される。
【００１８】
また、挟持体３０の他方側部分３０ｃ、３０ｃには、図７に示すように、たとえば合成樹脂からなる開用操作部材４０が固着される。開用操作部材４０は、押圧することによって、金属ベース２０に対して挟持体３０の一方側部分３０ａをコイルばね３２の付勢力に抗して開くためのものである。開用操作部材４０は、図８〜図１０に示すように、板状の開用押圧部４２を有する。開用押圧部４２には、その厚み方向のほぼ中央に、挟持体３０の他方側部分３０ｃ、３０ｃに対応する２つの孔４４、４４が形成される。これらの孔４４、４４には、挟持体３０の他方側部分３０ｃ、３０ｃが圧入される。開用押圧部４２の表面には、断面半円形状の２条の滑り止４６、４６が形成される。また、開用押圧部４２の裏面には、断面略扇形の２つの係合用突部４８、４８が間隔を隔てて形成される。さらに、開用押圧部４２の端部には、孔４４、４４の近傍に、断面Ｕ字状の２つの軸受け部５０、５０が間隔を隔てて形成される。
【００１９】
開用操作部材４０には、図７に示すように、挟持体３０の一方側部分３０ａ側に、たとえば合成樹脂からなる閉用操作部材６０が取り付けられる。閉用操作部材６０は、押圧することによって、後述の係合部材９４を変形して係合部材９４を開用操作部材４０から外し、挟持体３０の一方側部分３０ａをコイルばね３２の付勢力で閉じるためのものである。閉用操作部材６０は、図１１〜図１３に示すように、曲板状の閉用押圧部６２を有する。閉用押圧部６２の表面には、断面半円形状の２条の滑り止６４、６４が形成される。また、閉用押圧部６２の端部には、円柱状の突出部６６が形成される。突出部６６の両側には、円柱状の２つの軸６８、６８が形成される。閉用操作部材６０の突出部６６は開用操作部材４０の軸受け部５０、５０間に配置され、閉用操作部材６０の軸６８、６８は開用操作部材４０の軸受け部５０、５０で支持される。それによって、閉用操作部材６０は、開用操作部材４０に、軸６８、６８を中心として回動可能に支持される。この場合、軸６８、６８は、挟持体３０の中間部分３０ｂ、３０ｂ間に、中間部分３０ｂ、３０ｂと同一軸上に配置される。また、閉用押圧部６２は、開用押圧部４２から見て挟持体３０の一方側部分３０ａ側に形成される。さらに、閉用操作部材６０の突出部６６には、閉用押圧部６２の反対側に、板状の押圧片７０が形成される。押圧片７０は、閉用押圧部６２を押圧することによって閉用押圧部６２とともに軸６８、６８を中心にして回動して後述の係合部材９４を押圧するためのものである。この押圧片７０が回動する支点から押圧片７０の先端までの長さは、閉用押圧部６２が回動する支点から閉用押圧部６２の先端までの長さより短い。
【００２０】
金属ベース２０、挟持体３０、開用操作部材４０および閉用操作部材６０などは、たとえばＡＢＳ樹脂などの合成樹脂からなる樹脂ベース８０に取り付けられる。樹脂ベース８０は、図１４に示すように、長方形板状の主面部材８２を含む。主面部材８２には、略円形状の２つ取付孔８４、８４が間隔を隔てて形成される。主面部材８２の一端部の両側には、主面部材８２に沿って、金属ベース２０の支持部２８、２８に対応した曲面を有する２つの支え部８６、８６が形成される。支え部８６、８６は、支持部２８、２８を支えるためのものである。支持部８６、８６の近傍には、金属ベース２０の支持部２８、２８から突き出たコイルばね３２、３２の他端部分を逃がすための２つの逃げ用凹部８８、８８が形成される。支え部８６、８６間には、スリーブ３４、３４を保持するための断面Ｕ字状の２つの保持部９０、９０が形成される。また、保持部９０、９０間には、図１４および図１５に示すように、コ字状のスリット９２の内側に、弾性を有する矩形板状の係合部材９４が形成される。係合部材９４の両側には、２つの係合用凹部９６、９６が形成される。係合用凹部９６、９６間には、押圧用曲面部９８が形成される。さらに、スリット９２の中央には、半円形状の引掛け用孔１００が形成される。
【００２１】
樹脂ベース８０には、図７に示すように、保持部９０、９０に、スリーブ３４、３４が嵌められて保持される。この場合、樹脂ベース８０の主面部材８２および支え部８６、８６の上に、金属ベース２０の主面部材２２および支持部２８、２８がそれぞれ配置される。また、樹脂ベース８０の逃げ用凹部８８、８８に、コイルばね３２、３２の他端部分が配置される。さらに、樹脂ベース８０の係合部材９４の上方に開用操作部材４０の係合用突部４８が配置され、樹脂ベース８０の押圧用曲面部９８の上に閉用操作部材６０の押圧片７０が配置される。
【００２２】
金属ベース２０および樹脂ベース８０は、図２に示すように、２つのリベット１０２、１０２を金属ベース２０の取付孔２４、２４と、樹脂ベース８０の取付孔８４、８４と、台板１２の取付孔１６、１６とに通し、それらのリベット１０２、１０２を台板１２の下でかしめることによって、図１に示すように、台板１２の上に固定される。この場合、樹脂ベース８０の嵌合部材９４は、押圧して変形できるように、台板１２の切欠部１４に対応される。
【００２３】
図１に示す紙挟み１０では、図１６に示すように、開用操作部材４０の開用押圧部４２を押圧することによって、金属ベース２０の主面部材２２に対して挟持体３０の一方側部分３０ａをコイルばね３２、３２の付勢力に抗して開くことができる。この場合、挟持体３０において開こうとする一方側部分３０ａとは反対側の他方側部分３０ｃ、３０ｃに形成された開用押圧部４２を押圧すればよいので、開用操作部材４０が操作しやすく、挟持体３０を開きやすい。
【００２４】
また、図１に示す紙挟み１０では、図１７に示すように、係合部材９４の係合用凹部９６、９６が、金属ベース２０の主面部材２２に対して挟持体３０の一方側部分３０ａをコイルばね３２、３２の付勢力に抗して開いた状態で開用操作部材４０の係合用突部４８、４８に係合する。そのため、挟持体３０を開いた状態で維持することができる。
【００２５】
さらに、図１に示す紙挟み１０では、図１８に示すように、閉用操作部材６０の閉用押圧部６２を押圧することによって、押圧片７０で係合部材９４の押圧用曲面部９８を押圧し係合部材９４を変形して係合部材９４の係合用凹部９６、９６を開用操作部材４０の係合用突部４８、４８から外し、金属ベース２０の主面部材２２に対して挟持体３０の一方側部分３０ａをコイルばね３２、３２の付勢力で閉じることができる。この場合、挟持体３０において閉じようとする一方側部分３０ａ側に形成された閉用押圧部６２を押圧すればよいので、閉用操作部材６０が操作しやすく、挟持体３０を閉じやすい。
【００２６】
また、図１に示す紙挟み１０では、金属からなる挟持体３０が金属ベース２０に支持されているので、合成樹脂からなる挟持体を合成樹脂からなる基板で支持する場合に比べて、挟持体３０を強固に支持することができる。
【００２７】
さらに、図１に示す紙挟み１０では、係合部材９４が樹脂ベース８０の一部分で形成されているので、弾性を有する係合部材９４が形成しやすい。
【００２８】
また、図１に示す紙挟み１０では、押圧片７０が回動する支点から押圧片７０の先端までの長さは、閉用押圧部６２が回動する支点から閉用押圧部６２の先端までの長さより短いので、閉用押圧部６２をより弱い力で押圧することによって、係合部材９４を変形し、挟持体３０を閉じることができる。
【００２９】
なお、上述の紙挟み１０では、基板として、金属ベース２０および樹脂ベース８０が用いられいるが、この発明では、基板は金属のみあるいは合成樹脂のみで形成されてもよい。
【００３０】
また、上述の紙挟み１０では、付勢部材として金属からなるコイルばね３２が用いられているが、この発明では、金属からなるトーションばね、ゴムや合成樹脂などの弾性材料からなるばねなどが用いられてもよい。
【００３１】
さらに、上述の紙挟み１０では、金属ベース、挟持体および樹脂ベースなどが特定の形状を有するが、それらは他の形状に形成されてもよい。
【００３２】
【発明の効果】
この発明によれば、挟持体を開いた状態で維持することができ、しかも、挟持体を開閉しやすい、紙挟みが得られる。
