【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、前記台板に固定される基板と、一方側部分が前記基板に対して開閉できるように中間部分が前記基板に回動可能に支持される挟持体と、前記挟持体の一方側部分を前記基板側に付勢する付勢部材と、前記基板に対して前記挟持体の一方側部分を、前記付勢部材の付勢力に抗して開く開用操作部材と、前記基板に対して前記挟持体の一方側部分を前記付勢部材の付勢力に抗して開いた状態で、前記開用操作部材に係合する係合部材と、前記基板に対して前記挟持体の一方側部分を、前記付勢部材の付勢力で閉じる閉用操作部材とを含み前記開用操作部材は、前記挟持体の他方側部分に形成され、その裏面に係合用突部が形成された開用押圧部を有し、前記開用押圧部を押圧することによって前記基板に対して前記挟持体の一方側部分を前記付勢部材の付勢力に抗して開くように形成され前記係合部材は、弾性を有し、前記開用操作部材の係合用突部に係合するように形成され、前記閉用操作部材は、前記開用押圧部から見て前記挟持体の一方側部分側に形成される閉用押圧部と、前記開用操作部材に閉用押圧部を回転可能に支持する軸と、閉用押圧部とともに前記軸を中心にして回動して係合部材を押圧するための押圧片とを有し、前記閉用押圧部を押圧することによって押圧片が前記係合部材を変形して前記係合部材を前記開用操作部材の係合用突部から外し、前記基板に対して前記挟持体の一方側部分を前記付勢部材の付勢力で閉じるように形成された、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、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。

The present invention relates to a paper sandwicher, and more particularly, to a paper sandwicher provided with a sandwiching body on a base plate and capable of sandwiching a document or the like.
[0002]
[Prior art]
An example of a conventional paper sandwicher as the background of the present invention is disclosed in, for example, Japanese Patent No. 2623232. FIG. 19 is a perspective view showing an example of such a conventional paper sandwicher. A paper clip 1 shown in FIG. 19 includes a base plate 2. A clamping body 3 is provided at the end of the base plate 2. As for the clamping body 3, the one side part 3a is urged | biased toward the baseplate 2 with the torsion spring (not shown). Therefore, a document etc. can be clamped with the base plate 2 and the one side part 3a of the clamping body 3. FIG. A stopper member 4 is provided in the vicinity of the other side portion 3 b of the sandwiching body 3. The stopper member 4 is for locking the sandwiching body 3 in a state where the one side portion 3a of the sandwiching body 3 is opened against the urging force of the torsion spring with respect to the base plate 2. Furthermore, the stopper member 4 is for releasing the lock | rock of the clamping body 3 and closing the one side part 3a of the clamping body 3 by pressing it.
