Description

【考案の属する技術分野】
本考案は爪切りに関する。
【０００２】
【従来の技術】
一般的な爪切りは、ピンセット状に構成される上下の刃体と、両刃体の切刃どうしを接近操作する操作レバーなどで構成してある。操作レバーは、上下の刃体を上下に貫通する縦軸まわりに旋回操作でき、さらに、縦軸で支持される横軸まわりに起伏揺動できる。この種の爪切りにおいて、使用姿勢にした操作レバーが縦軸まわりに旋回移動するのを規制するために、操作レバーと上側の刃体との間に、互いに係合する旋回規制構造を設けることは公知である（特許文献１参照）。そこでは、支点突起が設けられる側の操作レバーの面壁に規制リブを設け、操作レバーと対向する上側の刃体の面壁に、先の規制リブと係合する溝を形成している。使用状態においては規制リブが溝内に嵌り込むので、操作レバーが縦軸まわりに旋回するのを規制できる。
【０００３】
使用時における操作レバーの旋回動作を規制することに加え、不使用時における操作レバーの旋回動作をも規制できるようにした爪切りが提案されている（特許文献２参照）。そこでは、不使用時における操作レバーをレバー長手方向へスライド操作することにより、操作レバーに固定した押板の切欠が上側の刃体に通設したスリットの周縁壁に係合して、不使用姿勢を保持し、同時に操作レバーの旋回動作を規制できるようになっている。
【０００４】
また、刃体によって切り取られた爪の破片が飛び散るのを防ぐため、爪切り本体の外側にケースを被せた爪切りが提案されている（特許文献３参照）。そこでは、爪切り本体のケースに対する前後動の限界を規制するために、下側の刃体の案内孔に、ケースの底壁に内向きに設けたストッパを係合させている。

【０００６】
【考案が解決しようとする課題】
特許文献１の爪切りによれば、使用時における操作レバーの旋回動作を規制して、上下の刃体を適正に接近操作できる。しかし、操作レバーを折り畳んで上側の刃体に沿わせた状態においては、操作レバーが縦軸まわりに自由に旋回でき、しかも規制リブが操作レバーの上面に突出するので、ポケットやバッグに爪切りを収納した場合に、旋回した操作レバーや規制リブが引っ掛かって取り出しにくいことがある。操作レバーとは別に、規制リブを備えた装飾板が必要になるので、爪切りの構成部品点数が多くなり、その分だけ爪切りのコストが高く付く。規制リブを操作レバーと一体に形成することは不可能ではないが、加工コストが高く付く。
【０００７】
特許文献２の爪切りによれば、使用時はもちろんのこと、不使用時における操作レバーの旋回動作も規制できるので、ポケットやバッグに爪切りを収納する場合でも、問題なく出し入れできる。しかし、操作レバーの縦軸の近傍にてこ支点が設けられているにもかかわらず、使用状態においては、押板に設けた溝（切欠）を支点にして、操作レバーがてこ作用を発揮する構造になっている。つまり、縦軸近傍のてこ支点より離れた位置にある押板の溝が、操作レバーのてこ支点になっており、その分だけ強い力で操作レバーを押し下げなければならず、操作しにくい。
【０００８】
特許文献３の爪切りによれば、上下の両刃体間の側面がケースで覆われているため、切爪が飛び散ることを防止でき、さらに案内孔とストッパとの係合が爪切り本体のケースに対する前後動の限界を規制するので、爪切り本体がケースから抜け外れない。しかし、爪切り本体のケースに対する前後動はどの位置においても固定されないので、使用の最中に前後方向にぐらつくことがあって使い勝手が悪い。また不使用時には両刃体の刃先が、ケースよりも前方でむき出しになっているため、爪切りをポケットやバッグに収納した場合に、刃先が他物を傷つけるおそれがある。
【０００９】
本考案の目的は、使用時はもちろんのこと、不使用時における操作レバーの旋回動作をも規制でき、従って、ポケットやバッグに収納する場合でも支障なく出し入れできる爪切りを提供することにある。本考案の目的は、旋回規制構造を備えていながらも、その構造を簡素化して爪切りの構成部品点数を増やさず、その分だけ製造コストが少なくて済む爪切りを提供することにある。本考案の目的は、切爪飛散防止用のケースを備えた爪切りにおいて、爪切り本体とケースとの前後方向の位置決めを図り、不使用時には刃先をケース内に収納して固定することができる爪切りを提供することにある。
【００１０】
【課題を解決するための手段】
本考案の爪切りは、図２に示すように上下一対の刃体２・３を備えた爪切り本体１と、両刃体２・３を接近操作する操作レバー４とを備えている。操作レバー４と爪切り本体１とは、爪切り本体１を上下に貫通する縦軸８と、縦軸８で支持される横軸１０とを介して連結されている。操作レバー４は、縦軸８まわりに旋回でき、また横軸１０まわりに起伏揺動できる。操作レバー４の揺動基端に、上側の刃体２と接当する支点突起５を設ける。操作レバー４と上側の刃体２との間に、操作レバー４の縦軸８まわりの旋回動作を規制する旋回規制構造を設ける。旋回規制構造は、上側の刃体２と操作レバー４との接当面に設けられて、互いに係合する突起１５と凹部１６とで構成する。これにより、使用姿勢と折り畳み姿勢のいずれの姿勢においても操作レバー４を旋回不能に姿勢保持できる。
【００１１】
具体的には、上側の刃体２の上面に突起１５を形成し、使用姿勢および折り畳み姿勢において突起１５と対向する操作レバー４の上下面に凹部１６を形成する。
【００１２】
突起１５は、上側の刃体２の壁面を上向きに塑性変形させて形成する。操作レバー４の揺動基端に、縦軸８との接当干渉を避ける逃げ溝９を利用して凹部１６を形成する。
【００１３】
別の旋回規制構造においては、操作レバー４の上下面に突起１５を形成し、操作レバー４を使用姿勢および折り畳み姿勢にした状態において、前記突起１５と対向する上側の刃体２の上面に凹部１６を形成する。
【００１４】
凹部１６は上側の刃体２の壁面を下向きに塑性変形させて形成し、操作レバー４の揺動基端の上下面のそれぞれに突起１５を形成する。
【００１５】
爪切り本体１の前方を開放して少なくともその両側方を覆う切爪飛散防止用のケース１３を備えた爪切りにおいては、上下の刃体２・３の両側縁に切欠３０を設け、ケース１３の側壁２６の内側には、係合突起２７を設ける。上下の両刃体２・３の前端及びこの切欠３０が、係合突起２７に係合することにより、爪切り本体１のケース１３に対する前後方向の位置決めを図る。
【００１６】
また、ケース１３は、前方を開放する箱体であって、底壁２４は前方に行くに従って天壁２３と離れるように傾斜しており、天壁２３と底壁２４とはそれぞれ前端から中央部にかけて切り欠かれて左右両側壁２６・２６が外方に弾性拡開変形するよう構成されている。前記切欠３０は、上下の刃体２・３の前方寄りの両側縁に前後二対ずつ設けることができる。
【００１７】
ケース１３を備えた爪切りにおいては、操作レバー４の縦軸８まわりの旋回動作を規制する上記の旋回規制構造を、操作レバー４と上側の刃体２又はケース１３の天壁２３との間に、設けることができる。この場合に旋回規制構造は、操作レバー４と上側の刃体２又はケース１３の天壁２３との接当面に設けられて、互いに係合する突起１５と凹部１６とで構成される。これによって使用姿勢と折り畳み姿勢のいずれの姿勢においても操作レバー４を旋回不能に姿勢保持できる。
【００１８】
【考案の作用効果】
本考案の爪切りにおいては、上側の刃体２と操作レバー４との接当面に設けられて互いに係合する突起１５と凹部１６とで旋回規制構造を構成し、使用姿勢と折り畳み姿勢のいずれの姿勢においても突起１５と凹部１６とが係合する。これによって使用時はもちろんのこと、不使用時における操作レバー４の旋回動作をも規制でき、ポケットやバッグに収納する場合でも支障なく出し入れできる爪切りが得られる。
【００１９】
上側の刃体２の上面に突起１５を形成し、使用姿勢および折り畳み姿勢において突起１５と対向する操作レバー４の上下面に凹部１６を形成した爪切りによれば、使用姿勢と折り畳み姿勢のいずれの状態においても、突起１５が凹部１６内に収容されるので、突起１５に他物が引っ掛かるのを防止でき、ポケットやバッグに収納した爪切りの出し入れをさらに円滑に行うことができる。
【００２０】
上側の刃体２の壁面を上向きに塑性変形させて突起１５を形成し、縦軸８との接当干渉を避ける逃げ溝９を利用して凹部１６を形成した爪切りによれば、旋回規制構造を備えていながら爪切りの構成部品点数を増やさずに済み、その分だけ構造を簡素化して爪切りの製造コストを削減できる。
【００２１】
操作レバー４の上下面に突起１５を形成し、突起１５と対向する上側の刃体２の上面に凹部１６を形成した爪切りによれば、使用姿勢と折り畳み姿勢のいずれの姿勢においても突起１５と凹部１６とが係合して、使用時はもちろんのこと、不使用時における操作レバー４の旋回動作をも規制できる。刃体２の側に突起１５を設けると、操作レバー４を旋回操作して姿勢を変更するときに、操作レバー４の側縁が突起１５に接当干渉する可能性があるが、操作レバー４の側に突起１５を設けると、そのように接当干渉することがなく、使い勝手のよい爪切りが得られる。
【００２２】
上側の刃体２の壁面を下向きに塑性変形させて凹部１６を形成し、操作レバー４の揺動基端の上下面のそれぞれに突起１５を形成した爪切りによれば、旋回規制構造を備えていながら爪切りの構成部品点数を増やさずに済み、その分だけ構造を簡素化して爪切りの製造コストを削減できる。
【００２３】
ケース１３を備えた爪切りにおいて、上下の刃体２・３の両側縁に切欠３０が設けられていると、切欠３０とケース１３の内側に設けられた係合突起２７とが係合して爪切り本体１とケース１３との前後方向の位置決めを図ることができ、使用時には刃の位置が前後にぐらつくことなく安定して使用することができる。また不使用時には刃先がケース１３内に収納されて上下の刃体２・３の前端と係合突起２７とが係合して固定されるので、刃先が他物を傷つけることがない。
【００２４】
前記切欠３０が、上下の刃体２・３の前方寄りの両側縁に前後二対ずつ設けられていると、使用時、切爪清掃時、不使用時のそれぞれの場合において爪切り本体１をケース１３に対して前後方向に位置決めすることができる。その際に、ケース１３が、前方を開放する箱体であって、底壁２４が前方に行くに従って天壁２３と離れるように傾斜していると、ケース１３を握って操作レバー４を前方に押し出すことにより本体１を前方に移動させやすい。また、天壁２３と底壁２４とがそれぞれ前端から中央部にかけて切り欠かれていると、左右両側壁２６・２６が弾性的に外方に拡開変形し、上下の刃体２・３の両側縁が係合突起２７を乗り越えて各固定位置間で爪切り本体１を移動させやすい。
【００２５】
このようなケース１３を備えた爪切りに、前記の操作レバー４の旋回規制構造が設けてあると、使用時の操作レバー４の旋回を防止するので使い勝手がさらによくなり、不使用時には他物への引っ掛かりをなくすことができる。
【００２６】
【実施例】
（第１実施例）
本考案に係る爪切りの実施例を図１ないし図４に示す。図３において爪切りは、上下一対の刃体２・３を有する爪切り本体１と、両刃体２・３を接近操作する操作レバー４とからなる。両刃体２・３は、それぞれプレス加工と研削加工を経て形成してあり、一端上下に対向する切刃２ａ・３ａを備えており、他端の接合面同士がスポット溶接によって分離不能に一体化してある。上下の切刃２ａ・３ａは適当な隙間を間にして上下に対向している。
【００２７】
操作レバー４は亜鉛ダイキャスト成形品からなり、前端（揺動基端）の下面側に三角形状の支点突起５を一体に備えており、支点突起５に連続する前端周面を丸めて上側の刃体２の上面と摺接する摺接面６を形成している。レバー後端には指掛部７が形成してある。レバー前端には、縦軸８との接当干渉を避ける逃げ溝９が形成され、さらに横軸１０を装着するための水平のピン穴１１が形成してある。
【００２８】
操作レバー４と爪切り本体１とは、上下の切刃２ａ・３ａの遊端寄りにおいて爪切り本体１を上下に貫通する縦軸８と、縦軸８で支持される横軸１０を介して連結する。これにより、操作レバー４は縦軸８まわりに旋回移動でき、さらに横軸１０まわりに起伏揺動して、使用姿勢（図１の状態）と折り畳み姿勢（図２の状態）とを切り換えることができる。縦軸８は頭付きの丸ピンからなり、その上端寄りに横軸１０用のピン穴１２が形成してある。横軸１０は小径の金属ピンからなる。
【００２９】
使用姿勢と折り畳み姿勢のいずれの姿勢においても操作レバー４を旋回不能に姿勢保持するために、操作レバー４と上側の刃体２との間に旋回規制構造を設ける。旋回規制構造は、上側の刃体２と操作レバー４との接当面に設けられて、互いに係合する突起１５と凹部１６とで構成する。操作レバー４の刃体２との接当面は、使用姿勢と折り畳み姿勢とで異なり、使用姿勢においては支点突起５の揺動基端側の傾斜面５ａが刃体２と接当し（図１参照）、折り畳み姿勢においては支点突起５と対向する平坦面４ａが刃体２と接当する（図２参照）。
【００３０】
図３および図４に示すように、突起１５は上側の刃体２の壁面を上向きに突出変形させて形成し、使用姿勢および折り畳み姿勢において突起１５と対向する操作レバー４の上下面に凹部１６を形成する。この実施例では、先に説明した逃げ溝９の上下の開口縁部を利用して凹部１６とした。本来、逃げ溝９は、例えば図７に示すように縦軸８との接当干渉を避ける奥行き寸法があればよいが、逃げ溝９を利用して凹部１６とするために、図２に示すように、従来の爪切りに比べてその奥行き寸法Ｗを拡大し、溝奥端が支点突起５の支点部分より後ろ側の傾斜面５ｂの途中まで開口するようにした。
【００３１】
図３に示すように、突起１５の塑性加工を容易にするために、その前後の壁面に捨穴１７を打抜き形成する。これら捨穴１７のうち、前側の捨穴１７を縦軸８の挿通穴１８として利用することにより、別途、挿通穴１８を形成する手間を省いて、刃体２の加工工数を減らすことができる。下側の刃体３には、縦軸８の直径寸法よりやや大きめの挿通穴１９が通設してある。
【００３２】
上記のように、突起１５を刃体２と一体に形成し、凹部１６を逃げ溝９を利用して形成すると、旋回規制構造を付加しているにもかかわらず部品点数が増加するのを防止できるので、旋回規制構造を備えている爪切りを従来の爪切りと同程度のコストで製造できる。また、使用時はもちろんのこと、不使用時においても操作レバー４が縦軸８まわりに旋回するのを規制できるので、爪切りをポケットやバッグに収納する場合でも他物に引っ掛かることなく出し入れできる。この実施例の爪切りは、従来の爪切りと同様に使用する。
【００３３】
図５は突起１５の変形例を示す。そこでは、上側の刃体２の壁面を上向きに折り起こして、左右一対の突起１５を形成した。この実施例によれば、突起１５と凹部１６の係合長さを大きくとることができるので、操作レバー４の旋回をさらに確実に防止できる。上下の凹部１６は区分壁２１によって区切られて独立した凹みとして形成してある。他は先の実施例と同じであるので、同じ部材に同じ符号を付してその説明を省略する。以下の実施例においても同じ扱いとする。
【００３４】
（第２実施例）　図６および図７は、本考案に係る爪切りの別の実施例を示す。そこでは、操作レバー４の上下面のそれぞれに突起１５を形成し、両突起１５と対向する上側の刃体２の上面に凹部１６を形成する点が先の実施例と異なる。詳しくは、片方の突起１５を、支点突起５の支点部分の近傍で、前側の傾斜面５ａの幅方向中央部に形成し、他方の突起１５を、レバーの前端寄りの平坦面４ａの幅方向中央部に形成する。凹部１６は上側の刃体２の壁面を下向きに塑性変形させて形成する。
【００３５】
（第３実施例）　図８および図９は、本考案に係る爪切りのさらに別の実施例を示す。そこでは、操作レバー４の下面に突起１５を、上面に凹部１６をそれぞれ形成し、これら両者に対応する凹部１６と突起１５とを上側の刃体２の上面に形成する点が、先の実施例と異なる。詳しくは、操作レバー４の支点突起５の近傍に突起１５を形成し、指掛部７の上面に凹部１６を形成する。上側の刃体２の側には、上面の前端寄りに、操作レバー４の突起１５に対応する凹部１６を形成し、上下の刃体２・３の接合固定部分の上面に、指掛部７の凹部１６に係合する突起１５を設ける。両刃体２・３の接合固定部分に設けた突起１５は、上下の刃体２・３をかしめ固定する締結具を兼ねることができ、その場合には、両刃体２・３をスポット溶接することは必ずしも要しない。
【００３６】
（第４実施例）
図１０ないし図１３は、爪切り本体１と操作レバー４とのほかに、切爪飛散防止用のケース１３を備えた爪切りに関する実施例を示す。図１３に示すように、上下の刃体２・３のそれぞれ前方寄りの両側縁には、半円形の切欠３０が、前側の切欠３０ａ・３０ａ、後ろ側の切欠３０ｂ・３０ｂのそれぞれ二対ずつ設けられている。操作レバー４の平坦面４ａの後端には、旋回規制構造として突起１５が設けられている。突起１５の前側面は図１１に示すようになだらかに傾斜している。また、操作レバー４の傾斜面５ａには突起１５を設け、これに対応する凹部１６を上側の刃体２に設ける。
【００３７】
合成樹脂製のケース１３は、前方を開放した略箱体であって、図１３に示すように底壁２４は前方に行くに従って天壁２３と離れるように傾斜している。天壁２３と底壁２４とは、それぞれ前端から長手方向中央部にかけて大きく切り欠かれており、ケース１３の左右両側壁２６・２６が外方に向かって弾性的に拡開変形するように構成されている。左右両側壁２６・２６の前端には、前記切欠３０に係合し得るこれよりやや小径の半円柱状の係合突起２７が上下にわたって設けてある。ケース１３の後ろ側には、後端から中央方向に向かって上下に貫通する溝２８が設けられている。これにより爪切り本体１の後端寄りにストラップ孔３１を設けた場合に、ケース１３のうえからストラップ孔３１にキーホルダなどを通すことができる。溝２８は同時に、操作レバー４の後端の突起１５が係合する凹部１６の役割も果たす。
【００３８】
ケース１３の係合突起２７は、不使用時、使用時、切爪清掃時のそれぞれにおいて、図１２に示すように、両刃体２・３の前端、両刃体２・３の前側の切欠３０ａ、後ろ側の切欠３０ｂにそれぞれ係合して爪切り本体１をケース１３に対して各位置で固定する。ケース１３の左右両側壁２６・２６を外方に弾性変形させることにより、爪切り本体１の両側縁は係合突起２７を乗り越えて各位置間を移動することができる。不使用時には両刃体２・３の前端に係合突起２７が係合することにより、両切刃２ａ・３ａを完全にケース１３内に収納して固定することができ、携帯の際に他物を傷つけることがない。また、使用時には前側の切欠３０ａと係合突起２７とが係合し、使用時に前後方向にぐらつくことなく安定して爪切り作業を行うことができ、切爪の飛散も確実に防止できる。後ろ側の切欠３０ｂと係合突起２７とを係合させると、両刃体２・３内にたまった切爪を捨てる際に爪切り本体１がケース１３に対して前後に移動することがなく、便利である。
【００３９】
上記の構成の爪切りにおいて、操作レバー４を折り畳んだ状態においては、図１１に示すようにケース１３の溝２８に、操作レバー４の突起１５が係合しており、操作レバー４の旋回が規制される。この状態から、操作レバー４の後端を前方に押すと、操作レバー４の後端に設けられた突起１５の前側の傾斜面が溝２８の前端縁に乗り上がり、操作レバー４がケース１３の天壁２３から浮き上がって指でつかみやすくなる。操作レバー４を旋回移動した使用姿勢においては、図１０に示すように傾斜面５ａ側の突起１５が、上刃体２の上面に設けた凹部１６に嵌り込み、使用時の旋回を規制する。
【００４０】
上記の実施例以外に、図１で説明した凹部１６は、逃げ溝９とは別に形成することができ、その場合の凹部１６は、図５で説明した凹部１６と同様に区分壁２１を設けて形成することができる。図６で説明した突起１５は、操作レバー４に別体のピンを打ち込んで形成することができる。係合突起２７は、縦長に形成する以外に、上下の各刃体２・３の切欠３０にそれぞれ係合するように上下の各位置に複数設けることができる。

[Technical field to which the invention belongs]
The present invention relates to nail clippers.
[0002]
[Prior art]
A general nail clipper includes upper and lower blades configured in a tweezer shape, an operation lever for operating the cutting blades of both blades to approach each other, and the like. The operation lever can be turned around a vertical axis penetrating the upper and lower blades vertically, and can swing up and down around a horizontal axis supported by the vertical axis. In this type of nail clipper, a rotation restricting structure that engages with each other is provided between the operation lever and the upper blade in order to restrict the operation lever in the use posture from turning around the vertical axis. Is known (see Patent Document 1). In this case, a regulating rib is provided on the face wall of the operation lever on the side where the fulcrum projection is provided, and a groove for engaging with the preceding regulating rib is formed on the face wall of the upper blade body facing the operation lever. In the use state, the restricting rib fits into the groove, so that the operation lever can be restricted from turning around the longitudinal axis.
[0003]
There has been proposed a nail clipper that can restrict the turning operation of the operating lever when not in use, in addition to restricting the turning operation of the operating lever when not in use (see Patent Document 2). Here, when the operating lever is not used, the notch of the push plate fixed to the operating lever is engaged with the peripheral wall of the slit provided in the upper blade body by sliding the operating lever in the longitudinal direction of the operating lever. The posture is maintained, and at the same time, the turning operation of the operation lever can be restricted.
[0004]
Further, a nail clipper in which a case is placed on the outside of a nail clipper body has been proposed to prevent fragments of the nail clipped by the blade body from scattering (see Patent Document 3). Here, in order to regulate the limit of forward and backward movement of the nail clipper body with respect to the case, a stopper provided inward on the bottom wall of the case is engaged with the guide hole of the lower blade body.

[0006]
[Problems to be solved by the invention]
According to the nail clipper of Patent Literature 1, the turning operation of the operation lever during use can be restricted, and the upper and lower blades can be appropriately approached. However, when the operating lever is folded and aligned with the upper blade, the operating lever can freely rotate around the vertical axis, and the regulating rib projects from the upper surface of the operating lever. When the is stored, the swiveled operation lever or the regulating rib may be caught and difficult to remove. Since a decorative plate having a regulating rib is required separately from the operation lever, the number of components of the nail clipper increases, and the cost of the nail clipper increases accordingly. Although it is not impossible to form the regulating rib integrally with the operation lever, the processing cost is high.
[0007]
According to the nail clipper of Patent Literature 2, since the turning operation of the operation lever when not in use, as well as during use, can be restricted, even when the nail clipper is stored in a pocket or a bag, it can be taken in and out without any problem. However, in spite of the fact that a lever is provided near the longitudinal axis of the operating lever, the operating lever exerts a lever action using the groove (notch) provided in the push plate as a supporting point in a use state. It has become. That is, the groove of the push plate at a position away from the lever fulcrum near the vertical axis is the lever fulcrum of the operation lever, and the operation lever must be pushed down by a correspondingly strong force, making it difficult to operate.
