Description

【０００１】
【発明の属する技術分野】
本発明は、筆記具や化粧具等の軸筒やキャップ等の筒体に前後方向に揺動可能に装着されて、この揺動支持点から玉部を有する前端側が筒体表面に適宜の挟持力により常に付勢接触されており、該揺動支持点より後端側の操作部を筒体側へ押圧することにより、玉部を有する前端側が筒体表面から離れ、この開状態にて衣服の胸ポケットやノート等の被挾着物への挟み込み挟持を可能とするバインダー式のクリップに関する。
【０００２】
【従来の技術】
この種の動きを成すバインダー式のクリップは、実用新案登録第３０４３７２１号（以後、前者）、そして実用新案登録第３０４６６４９号や特開２０００-７９７９２号（以後、後者）に公表されているものが知られている。
即ち、上記前者のものは、クリップ部が、軸受、支持軸により筒体の表面に前後揺動可能に軸着され、クリップ部の後端側裏面に設けた突出片（伝導片）が位置する筒体の筒壁部位には略コの字状の切欠き溝を設けることで、筒方向に長くその一端を反発基部とする反発舌片を形成し、この舌片により、前記軸受、支持軸からなる軸着部を揺動支持点としてクリップ部の前端側が筒体表面に常に付勢接触されるように構成されている。
【０００３】
また、後者のものは、クリップ部が、回転軸により筒体の表面に前後揺動可能に軸着され、クリップ部の後端側と筒体との間にねじりバネや板バネ等のバネ材を設け、このバネ材により、前記軸着部を揺動支持点とするクリップ部の前端側が筒体表面に常に付勢されるように構成されている。
【０００４】
【発明が解決しようとする課題】
ところで、筆記具や化粧具等の小物製品は生産性とロット数が収益に大きく影響するものであるが、上記前者の場合はクリップ部に支持軸、そして突出片を設け、筒体側には軸受、反発舌片形成用の切欠き溝を設ける等の構造が複雑となり、加工と組み立てに手間が掛かる。
また、クリップ部の取り付けは支持軸を軸受間に架橋状に挿し込むといった構造であることから、クリップ部の揺動開閉操作が頻繁に行われることで、軸受の軸挿通口が磨耗を来たして軸受から支持軸が離脱し、クリップ部が外れる等の品質性にも問題があった。また、クリップ部の支持軸や軸受が筒体表面に露出する構造であることで、高級な筆記具には不向きな構造である。
【０００５】
後者の場合にはクリップ部の筒体への取付け部品点数が多く構造が複雑になり、筒体への組み付けに手間が掛かる等の欠点が存在していた。また、部品点数が多く構造が複雑であるために、故障等も多くなる問題がある。同時前者と同様に高級な筆記具には不向きな構造である。
【０００６】
また、上記の前者や後者のように、後端側操作部を筒体側へ押圧することにより、前端側が筒体表面から離れる動きを成すクリップについてはＵＳ５，６０１，３７６（以後、ＵＳ）やＷＯ９９／４２３０４（ＰＣＴ／ＥＰ９８／０４２０４）（以後、ＷＯ）においても公表されている。
ＵＳ特許において公表されているクリップは、筒体の後端側表面に設けた装着ブロックを抱き込むように係合させる爪部をクリップ部の後端側両側に内向きに設け、クリップ部の後端には裏面側に向けて折り返すようにバネ部を設け、このバネ部により、前記爪部による係合部を揺動支持点としてクリップ部の前端側が筒体表面に常に付勢接触されるように構成されている。
【０００７】
ＷＯ特許において公表されているクリップは、クリップ部の後端側裏面に、クリップ部の両折り曲げ縁から延設させると共に合せ縁が互いに接近するように内向きに折り曲げ且つクリップ部の前端側に突出させた挿入部を設け、この挿入部を筒体の後端側に設けられている固定部に挿入により取り付けることで、この挿入部のクリップ部に対する接続基部を揺動支持点としてクリップ部の前端側が筒体表面に常に付勢接触され、後端側の湾曲状に反り上げた操作部を筒側に押圧することにより、前端側が筒体表面から離れる動きを成すように構成されている。
【０００８】
本発明はこの様な従来事情に鑑みてなされたもので、その目的とする処は、筒体への組み付けが容易で、クリップ部に挟持力を付与するバネ支点の短期劣化を防いで長期に亘り品質の保障が期待でき、しかも、外観がシンプルな筆記具や化粧具等の小物製品に有効なバインダー式のクリップを提供することにある。
【０００９】
【課題を達成するための手段】
上記目的を達成するために請求項１の発明は、筆記具や化粧具等の軸筒又はキャップ等の筒体に前後揺動可能に装着されて、該揺動開閉支点より前端側が筒体表面に付勢接触されており、同揺動開閉支点より後端側の操作部を前記筒体側に押されることにより、玉部を有する前端側が筒体表面から離れ、衣服の胸ポケットやノート等の被挾着物へ差し込むことができるクリップにおいて、
クリップ部と、このクリップ部の裏面に設けられる弾性部と、この弾性部の他端に一体に形成されて筒体に取り付けられる取付部とで構成され、
前記クリップ部は、後端側操作部を押した時に筒体表面との接触部がクリップ部の揺動支持点となるように筒体の表面に向けて突出させた支持脚部を備え、
前記弾性部は、クリップ部の裏面に固定的又は一体的に添設される取付片部を一端側に備えると共に、該取付片部から前記取付部に向けて連なる連設片部を備えて、該連設片部と取付片部との間にクリップ部の後端側操作部を押した時にクリップ部の揺動開閉支点となるように屈曲せしめた第１屈曲部を備え、
更に、前記連設片部と前記取付部との間にはクリップ部に挟持力を付与するバネ支点となるように屈曲せしめた第２屈曲部を備えてなることである。
【００１０】
そして、上記クリップ部が金属製の場合には弾性部をクリップ部の後端から裏面に向けた折り曲げ加工により一体に備えたり、弾性部をクリップ部とは別途に折り曲げ加工した後に、クリップ部の裏面にスポット溶接や圧入、或いはカシメ等の固着手段により備える。
また、クリップ部が樹脂製の場合には別途に製作した弾性部を溶着等の固着手段によりクリップ部の裏面に備える。
【００１１】
また、上記取付部の形状、即ち筒体に対する取付形状としては特に限定されるものではない。
例えば筒体の後端に圧入やネジ込み方式により組み込まれる止め具により挟み込むように軸方向に挾着される輪状のもの、又、筒体の後端外周に嵌め込み外嵌により取り付けられる筒状や一対の帯部からなるバンド状のもの、或いは両縁に鋸刃状の抜止爪を有し、筒体の後端に軸方向に設けられている挿入孔に圧入により取り付けられる折返し挿入片状のもの等が挙げられる。
【００１２】
また、請求項２の発明は、クリップ部の後端側操作部を押した時にクリップ部の揺動開閉支点となる第1屈曲部が、クリップ部の後端側裏面におけるクリップ部全長の略１／３近傍部位においてクリップ部の後端側操作部を押した時に揺動開閉支点となるように形成され、これにより、クリップ部の後端側操作部を筒体側に押す前端側の開操作を小さな力で軽く行い得るようにしたことにある。
【００１３】
【発明の実施の形態】
本発明の実施の具体例を図面に基づいて説明する。
図１は、本発明クリップＡの実施形態の一例を示し、１はクリップ部、２は弾性部、３は筒体４に挾着や外嵌或いは圧入等により取り付けられる取付部であり、筒体４は、筆記具や化粧具等の軸筒やキャップその他の携帯を可能とする小物製品の本体部である。
【００１４】
クリップ部１は、金属板を用いた曲げ加工、或いは溶融金属材料や合成樹脂材料を用いた型成形により形成される。図示では金属板を用いた一連の打ち抜き、曲げ加工により製作される金属製の例を示す。
このクリップ部１の前端裏面（筒体４との対向面）に玉部1-1が曲げ加工により形成され、該玉部1-1の後方側には後端側操作部５を押した時に筒体４表面との接触下端部6-1がクリップ部１の前後揺動支持点Ｐ1となるように筒体４の表面に向けて突出させた支持脚部６が曲げ加工により形成されている。
【００１５】
支持脚部６は、クリップ部１の幅方向両縁から同幅間隔にて平行且つ適宜の突出形状と高さにて筒体４の表面方向に曲げ加工により一体に形成され、筒体４表面に接触する下端接触部6-1が、後端側操作部５を押した時にクリップ部１の玉部1-1を有する前端側が持ち上げられ筒体４の表面から離れるクリップ部１の前後揺動支持点P0となるようにしてある（図の状態）。
つまり、弾性部２の弾発力（バネ力）に抗して後端側操作部５が押されると、支持脚部６の下端接触部6-1を揺動支持点P0にしてクリップ部１の筒体４表面に付勢接触する玉部側が持ち上げられ筒体の表面から離れるように形成してある。
【００１６】
弾性部２は、適宜の剛性とバネ性に優れた所望の金属板から一連の打ち抜き、曲げ加工により形成されるものである。
この弾性部２の他端側には筒体４後端のクリップ装着部７に止め具８より軸方向に挟み込まれる輪状(リング状)に打ち抜き加工された後に、筒体４の軸芯に対して略直交するように略鋭角に曲げ加工された取付部３が後述する第２屈曲部10を介して一体に形成されている。
【００１７】
而して、取付部３が筒体４のクリップ装着部７に止め具８より組み込み取り付けられることで、第２屈曲部10にはクリップ部１の前端側を筒体４表面に常に付勢接触させる挟持力（弾発力）が付与される。つまり、第２屈曲部10がクリップ部１に挾着力を付与するバネ支点Ｐ2となり、クリップ部１の前端側を筒体４表面に常に付勢接触させるように形成されている。
【００１８】
また、弾性部２の一端側にはスポット溶接等の固着手段によりクリップ部1の裏面に固定的に添設される取付片部2-1が同裏面に納まる程度の板幅で同裏面形状に沿うように曲げ加工により形成されている。
そして、この取付辺部2-1との間にクリップ部１の後端側操作部５を押した時にクリップ部１の揺動開閉支点P1となる第１屈曲部９を介して後方下向き傾斜状で第２屈曲部P2を介して前述の輪状取付部３に連設する連設片部2-2が曲げ加工により形成されている。
【００１９】
第１屈曲部９は、クリップ部１の後端側操作部５を筒体１側に押した時、玉部1-1を有するクリップ部１の前端側が筒体４表面から離れる際の揺動開閉支点Ｐ1となるように取付片部2-1と連設片部2-2との間に略鈍角状に折り曲げ形成されてなる。
【００２０】
第２屈曲部10は、玉部1-1を有するクリップ部１の前端側を筒体４表面に付勢接触させる適宜の挟持力（弾発力）を付与するバネ支点P2となるように連設片部2-2と輪状取付部３との間に略鈍角状に折り曲げ形成されてなる。
【００２１】
而して、以上のように構成された弾性部２の取付辺部2-1をクリップ部１の裏面にスポット溶接等の固着手段により取り付けることで、輪状取付部３を他端側に備える弾性部２がクリップ部１の裏面に具備される。
この時、第1屈曲部９がクリップ部１の後端側におけるクリップ部１全長の略１／３近傍部位においてクリップ部１の裏面に存在するように取付片部2-1のクリップ部１裏面への取付位置を考慮することが好ましい。
【００２２】
その理由としては、例えばクリップ部１の全長Ｌを40mmとし、250ｇの挟持力が得られるように設定し、揺動開閉支点Ｐ1となる第1屈曲部９が、クリップ部１の後端側におけるクリップ部１全長Ｌの略１／４部位においてクリップ部１の裏面に存在させた場合、後端側操作部５を筒体４側に押圧するために必要な力は875ｇになる。
また、第1屈曲部９をクリップ部１全長Ｌの略１／２部位においてクリップ部１の裏面に存在させた場合の力は438ｇとなり、前述の略１／４部位よりも押圧力が大幅に小さく（軽く）なることが実験の結果分かった。ところが、この様に第１屈曲部９をクリップ部１全長Ｌの略１／２部位に存在させることはクリップ部１の前端側が筒体４表面から離れる開き（開度）が前述の１／４よりもかなり小さくなり、例えば厚手のノート等の被挾着物Ｂへの差し込みが困難になる問題が生じる等の本発明の目的を達成することができなくなるからである。
【００２３】
これらの結果からクリップ部１の後端側操作部５を筒体４側に押す時の力が665ｇ程度で、しかも、クリップ部１の前端側の開きが厚手のノート等の被挾着物Ｂであっても何ら問題なくスムーズに差し込むことができる開き（開度）を、クリップ部１の玉部1-1と筒体４との間に確保することができる等を鑑みると、クリップ部１の揺動開閉支点Ｐ1となる第１屈曲部９をクリップ部１の後端側におけるクリップ部１全長Ｌの略１／３近傍部位においてクリップ部１の後端側裏面に存在するように弾性部２をクリップ部１の裏面に取り付け具備することが好ましいことが分かった。
【００２４】
また、クリップ部１の両支持脚部６における下端接触部6-1の筒体４表面への接触係止が、前述の第１屈曲部９から略直角に筒体４表面方向に向けた下方位置かそれよりも後方位置（筒体４の後端側）において行なわれるように両支持脚部６のクリップ部１両縁からの折り曲げ突出位置及び突出形状を考慮することが好ましい。
【００２５】
次に、以上の如く構成した本実施例詳述のクリップＡの筒体４への取り付け方を簡単に説明する。
まず、弾性部２の他端側に設けた輪状取付部３を、筒体４の後端に形成されているクリップ装着部７にセットし、その後、クリップ装着部７に輪状取付部３を挟み込むように止め具８を圧入やネジ込み方式により組み込む。
輪状取付部３が止め具８によりクリップ装着部７に挾着される取り付けがなされると、取付部３と弾性部２の連設片部2-2との第２屈曲部10には玉部1-1を有するクリップ部１の前端側を筒体４表面側に適宜の挟持力にて付勢接触させる弾発力が生じるものである。
【００２６】
次に、クリップＡが取り付けられた筒体４を使用するときの作用について説明する。
筒体４を衣類のポケットやノート等の被挾着物Ｂに差し込み保管する場合にはクリップ部１の後端側操作部５を筒体４側に押す。
すると、クリップ部１は筒体４表面に接触する両支持脚部６の下端接触部6-1を揺動支持点P0とし、且つ裏面弾性部２の第１屈曲部９を揺動開閉支点Ｐ1として、玉部1-1を有する前端側が持ち上げられ筒体４表面から離れる動きを成し、被挾着物Ｂを差し込み得る開き状態となる（図３の二点鎖線から実線の状態）。
【００２７】
この時、クリップ部１は筒体４表面に接触する両支持脚部６の下端接触部6-1を揺動支持点P0として揺動することで、輪状取付部３と第２屈曲部10を介してクリップ部１の裏面に向けた前方上向き傾斜状に連設する連設片部2-2が該第２屈曲部10から筒体４の表面方向に歪む（垂れる）ことはない。
即ち、後端側操作部５を筒体４側に押すクリップ部１の開操作時に、曲げ等の応力負荷をバネ支点P1となる第２屈曲部10に掛けることがないことから、クリップ部１の初期設定挟持力を長期に亘り保障することができる。
【００２８】
尚、クリップ部２の支持脚部５の高さや連設片部2-2の長さ、そしてクリップ部１のバネ支点Ｐ2となる第２屈曲部10の湾曲又は屈曲の大小等の曲げ形状は特に限定されるものではない。
また、図示を省略しているが、クリップ部１裏面への弾性部２の取り付けとしてはスポット溶接の他に、取付片部2-1を両側縁の鋸歯状の抜止爪を有する挿入片形状に形成する一方、クリップ部１の裏面には長さ方向両縁を内向き状に折り曲げた取付部を設けて、該取付部への圧入により取り付けるようにするも良い。
【００２９】
また、クリップ部１が樹脂製の場合には前述の圧入方式の他に、クリップ部１の裏面に溶着突起を数個並設的に設ける一方、弾性部２の取付片部2-1側には該溶着突起を貫通させる取付孔を設ける溶着方式等の適宜の固着手段によりクリップ部１の裏面に弾性部２を取り付けることが可能である。
【００３０】
図５は、本発明クリップA-1の他の実施形態を示す。
斯かる実施例においては筒体に取り付ける取付部11の形態を前述の輪状から後述する折返し挿入片状に変えた以外は前述の実施例詳述と基本的に同じことから、同じ構成部分に同じ符号を付することで重複する説明を省略する。
【００３１】
即ち、筒体４に取り付ける取付部11を、弾性部２の連設片部2-2から第2屈曲部10を介して筒体４の軸芯と略平行に折返し連設させて筒体４に設けられる挿入孔12に圧入される挿入片状に折り曲げ形成し、これにより、挿入片状の取付部11と前記連設片部2-2とを第2屈曲部10を介して略Ｕ字状に成すように連設させたバネ形状に折り曲げ形成してなる。
尚、挿入片状の取付部11の両縁には必要に応じて鋸刃状の抜止爪を設けるも勿論任意である。
【００３２】
図６に示すクリップA-2は、筒体４を両側から抱き込むように一対の帯部13-1を弾性部２の連設片部2-2から後方に向かって略筒状に折り曲げ突設させたバンド状の取付部13と成し、筒体４の後端外周に外嵌せしめることで、クリップ部１を筒体４に装着し得るように構成してなる。
尚、斯かる実施例では取付部12の形態をバンド状に変えた以外は前述の実施例詳述と基本的に同じことから、同じ構成部分に同じ符号を付することで重複する説明を省略する。
【００３３】
図７は、弾性部２をクリップ部１から曲げ加工により一体に形成した他の実施形態を示す。
斯かる実施例のクリップA-3は、弾性部２の取付片部2-1をクリップ部１の後端から裏面に向けて折り返し添設するように折り曲げ加工せしめて当該裏面に、輪状の取付部３を他端側に備える弾性部２を一体に具備せしめたクリップ部１と弾性部２との一体型構造に折り曲げ構成してなるものである。
この様に、斯かる実施例ではクリップ部１と弾性部２とを一体型構造に変えた以外、前述の実施例詳述と基本的に同じことから、同じ構成部分に同じ符号を付することで重複する説明を省略する。
【００３４】
【発明の効果】
本発明のバインダー式のクリップは叙上の如く構成してなることから下記の作用効果を奏する。
玉部を有するクリップ部の前端側を筒体表面に付勢接触させる挟持力のバネ支点Ｐ2とは別途に、クリップ部の後端側操作部を押した時のクリップ部の前後の揺動支持点P0となる支持脚部をクリップ部自体に設けて、この支持脚部の筒体表面に接触する下端接触部を揺動支持点P0としてクリップ部の前端側を筒体表面から持ち上げて離すクリップ部の開操作を行うことができるように構成したことで、操作部を筒体側に押すクリップ部の開操作時における屈曲応力等の負荷をバネ支点Ｐ2となる弾性部と取付部との第２屈曲部に掛けることがない。
従って、頻繁に行なわれるクリップ部の開操作により挟持力のバネ支点Ｐ2が金属疲労（弾性疲労）を起こすことがない。よって、クリップ部の初期設定挟持力を長期に亘り維持することができることで、品質の安定性が保障されるバインダー式のクリップを提供することができる。
【００３５】
また、クリップ部の揺動開閉支点Ｐ0となる第1屈曲部を、クリップ部の後端側裏面におけるクリップ部全長の略１／３近傍部位に存在させてなることで、筒体表面に接触するクリップ部の挟持力と後端側操作部を押した時に筒体表面から離れる前端側の開き（開度）を被挾着物への差し込みに支障ない状態に確保しながら、後端側操作部を押す時の力を小さくすることができる。つまり、操作部を筒体側に押すクリップ部の開操作を小さな力で軽く行なうことができることで、操作性、取扱い性に優れたバインダー式のクリップを提供することができる。
【００３６】
また、バインダー式でありながら、弾性部の他端側に設けた取付部を挾着又は外嵌又は圧入等の簡単な取付構造、即ち、一般的な金属製クリップの取付手段として従来から採用されている輪状や一対の帯部からなるバンド状、或いは折返し挿入片状等の簡単な構造にてクリップ部を筒体に取り付けることができる。
従って、構造の複雑化と組立性に難色を有する支持軸や回転軸、更にはバネ材等を用いる従来構造に比べて、構造が簡素化されて組立作業性が頗る簡便となり、生産性の向上が期待でき、ひいてはコスト的にも有利になる。

BACKGROUND OF THE INVENTION
The present invention is attached to a cylindrical body such as a writing instrument or a cosmetic tool and a cylindrical body such as a cap so as to be swingable in the front-rear direction, and the front end side having the ball portion from the swing support point has an appropriate clamping force on the surface of the cylindrical body. The front end side having the ball part is separated from the cylinder surface by pressing the operation part on the rear end side from the swinging support point toward the cylinder side, and the chest of the garment is opened in this open state. The present invention relates to a binder-type clip that can be sandwiched and held in an article to be worn such as a pocket or a notebook.
[0002]
[Prior art]
Binder-type clips that perform this type of movement are those disclosed in Utility Model Registration No. 3043721 (hereinafter the former), Utility Model Registration No. 3046649 and Japanese Patent Application Laid-Open No. 2000-79792 (hereinafter the latter). Are known.
That is, in the former, the clip portion is pivotally mounted on the surface of the cylinder body by a bearing and a support shaft so as to be able to swing back and forth, and a protruding piece (conductive piece) provided on the back surface of the rear end side of the clip portion is located. By providing a substantially U-shaped notch groove in the cylindrical wall portion of the cylindrical body, a repelling tongue piece that is long in the cylindrical direction and has one end as a repulsive base is formed. The front end side of the clip part is always in urging contact with the surface of the cylindrical body, with the pivoting part made of
[0003]
In the latter, the clip portion is pivotally attached to the surface of the cylinder body by a rotating shaft so as to be able to swing back and forth, and a spring material such as a torsion spring or a leaf spring is provided between the rear end side of the clip portion and the cylinder body. The front end side of the clip portion with the pivoting support point as the pivot support point is always urged against the surface of the cylindrical body by the spring material.
[0004]
[Problems to be solved by the invention]
By the way, for small products such as writing instruments and cosmetics, productivity and the number of lots greatly affect profit, but in the former case, a support shaft and a protruding piece are provided on the clip part, and a bearing is provided on the cylindrical body side. A structure such as providing a notch groove for forming a repulsive tongue piece becomes complicated, and it takes time and effort to process and assemble.
In addition, since the clip part is attached in a structure in which the support shaft is inserted between the bearings in a bridging manner, frequent opening and closing operations of the clip part cause wear of the shaft insertion port of the bearing. There was also a problem in quality, such as the support shaft being detached from the bearing and the clip part coming off. Further, since the support shaft and the bearing of the clip portion are exposed on the surface of the cylindrical body, the structure is not suitable for high-grade writing instruments.
[0005]
In the latter case, the number of parts to be attached to the cylinder of the clip portion is large and the structure is complicated, and there are drawbacks such as time and effort for assembling to the cylinder. In addition, since the number of parts is large and the structure is complicated, there is a problem that failures and the like increase. Similar to the former, the structure is unsuitable for high-grade writing instruments.
[0006]
Further, as in the former and the latter, a clip in which the front end side moves away from the cylinder surface by pressing the rear end side operation portion toward the cylinder side is disclosed in US Pat. / 42304 (PCT / EP98 / 04204) (hereinafter referred to as WO).
The clip disclosed in the US patent is provided with a claw portion that engages the mounting block provided on the rear end surface of the cylindrical body inward on both sides of the rear end side of the clip portion. A spring part is provided at the end so as to be folded back toward the back side, and the spring part always urges and contacts the front end side of the clip part to the surface of the cylinder with the engaging part by the claw part as a swing support point. It is configured.
[0007]
The clip published in the WO patent is extended inward from the both bent edges of the clip portion on the back surface of the rear end side of the clip portion, and is bent inward so that the alignment edges approach each other, and protrudes to the front end side of the clip portion. The insertion portion is provided, and the insertion portion is attached to a fixing portion provided on the rear end side of the cylinder by insertion, so that the connection base to the clip portion of the insertion portion serves as a swing support point, and the front end of the clip portion The front end is always in urging contact with the cylindrical body surface, and the front end side is configured to move away from the cylindrical body surface by pressing the operation portion that is curved in a curved shape on the rear end side toward the cylindrical side.
[0008]
The present invention has been made in view of such conventional circumstances, and the purpose of the present invention is that it is easy to assemble to the cylinder, and prevents the spring fulcrum that imparts clamping force to the clip portion from being deteriorated for a long time. It is an object of the present invention to provide a binder-type clip that can be expected to guarantee quality and that is effective for small articles such as writing instruments and cosmetics that have a simple appearance.
[0009]
[Means for achieving the object]
In order to achieve the above object, the invention of claim 1 is attached to a cylindrical body such as a writing instrument or a cosmetic tool or a cylindrical body such as a cap so as to be able to swing back and forth. When the operation part on the rear end side from the swing opening / closing fulcrum is pushed to the cylinder side, the front end side having the ball part is separated from the surface of the cylinder, and the chest pocket of the clothes, the notebook, etc. In a clip that can be inserted into a kimono,
A clip portion, an elastic portion provided on the back surface of the clip portion, and an attachment portion integrally formed on the other end of the elastic portion and attached to the cylinder,
The clip part includes a support leg that protrudes toward the surface of the cylinder so that when the rear end side operation part is pressed, the contact part with the surface of the cylinder becomes a swing support point of the clip part,
The elastic portion includes an attachment piece portion fixedly or integrally attached to the back surface of the clip portion on one end side, and a continuous piece portion continuous from the attachment piece portion toward the attachment portion. A first bent portion bent between the continuous piece portion and the attachment piece portion so as to be a swing opening / closing fulcrum of the clip portion when the rear end side operation portion of the clip portion is pushed;
Further, a second bent portion bent between the continuous piece portion and the attachment portion so as to serve as a spring fulcrum for applying a clamping force to the clip portion is provided.
[0010]
When the clip portion is made of metal, the elastic portion is integrally provided by bending from the rear end of the clip portion toward the back surface, or the elastic portion is bent separately from the clip portion, It is provided on the back surface by fixing means such as spot welding, press fitting, or caulking.
Further, when the clip part is made of resin, a separately manufactured elastic part is provided on the back surface of the clip part by fixing means such as welding.
[0011]
Further, the shape of the mounting portion, that is, the mounting shape with respect to the cylindrical body is not particularly limited.
For example, a ring-shaped one that is attached in the axial direction so as to be sandwiched by a stopper incorporated by press-fitting or screwing into the rear end of the cylinder, or a cylinder that is fitted on the outer periphery of the rear end of the cylinder and attached by external fitting A band-shaped one consisting of a pair of band parts, or a folded-in insert piece-like shape that has saw blade-shaped retaining claws on both edges and is fitted by press-fitting into an insertion hole provided in the axial direction at the rear end of the cylinder.

This is because it can be done lightly with a small force.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
A specific example of the embodiment of the present invention will be described with reference to the drawings.
FIG. 1 shows an example of an embodiment of the clip A of the present invention. Reference numeral 1 denotes a clip part, 2 denotes an elastic part, 3 denotes an attachment part attached to the cylinder body 4 by fitting, external fitting, press fitting, or the like. Reference numeral 4 denotes a main body of a small product that can be carried such as a shaft tube, a cap, or the like such as a writing instrument or a cosmetic tool.
[0014]
The clip portion 1 is formed by bending using a metal plate or molding using a molten metal material or a synthetic resin material. In the drawing, an example of metal made by a series of punching and bending using a metal plate is shown.
When the ball portion 1-1 is formed by bending on the back surface of the front end of the clip portion 1 (the surface facing the cylindrical body 4), when the rear end side operation portion 5 is pushed behind the ball portion 1-1, A support leg 6 projecting toward the surface of the cylinder 4 is formed by bending so that the lower end portion 6-1 of contact with the surface of the cylinder 4 is the front and rear swing support point P1 of the clip 1. .
[0015]
The support leg 6 is integrally formed by bending in the surface direction of the cylindrical body 4 in parallel with the same width interval from the both edges in the width direction of the clip part 1 and at an appropriate protruding shape and height. When the rear end side operation part 5 is pushed, the lower end contact part 6-1 that contacts the front end side of the clip part 1 having the ball part 1-1 is lifted and the clip part 1 swings back and forth away from the surface of the cylindrical body 4 The support point P0 is set (the state shown in the figure).
That is, when the rear end side operation portion 5 is pushed against the elastic force (spring force) of the elastic portion 2, the clip portion 1 uses the lower end contact portion 6-1 of the support leg portion 6 as the swing support point P0. The ball part side that is in urging contact with the surface of the cylindrical body 4 is lifted and formed away from the surface of the cylindrical body.
[0016]
The elastic portion 2 is formed by a series of punching and bending processes from a desired metal plate having an appropriate rigidity and spring property.
On the other end side of the elastic portion 2, after being punched into a ring shape (ring shape) sandwiched in the axial direction from the stopper 8 at the clip mounting portion 7 at the rear end of the cylindrical body 4, The mounting portion 3 bent at a substantially acute angle so as to be substantially orthogonal to each other is integrally formed via a second bent portion 10 described later.
[0017]
Thus, the mounting portion 3 is mounted and attached to the clip mounting portion 7 of the cylindrical body 4 by the stopper 8, so that the front end side of the clip portion 1 is always urged into contact with the surface of the cylindrical body 4 at the second bent portion 10. The clamping force (elasticity) to be applied is given. That is, the second bent portion 10 serves as a spring fulcrum P2 that gives a clamping force to the clip portion 1, and is formed so that the front end side of the clip portion 1 is always in urging contact with the surface of the cylindrical body 4.
[0018]
In addition, an attachment piece 2-1 fixedly attached to the back surface of the clip portion 1 by a fixing means such as spot welding is attached to one end side of the elastic portion 2 so that the back surface shape has a plate width enough to fit in the back surface. It is formed by bending so as to follow.
And when the rear end side operation part 5 of the clip part 1 is pushed between this attachment side part 2-1, it is inclined backward and downward via the first bent part 9 which becomes the swing opening / closing fulcrum P1 of the clip part 1. Thus, the connecting piece 2-2 connected to the above-described ring-shaped mounting portion 3 through the second bent portion P2 is formed by bending.
[0019]
The first bent portion 9 swings when the front end side of the clip portion 1 having the ball portion 1-1 moves away from the surface of the cylindrical body 4 when the rear end side operation portion 5 of the clip portion 1 is pushed toward the cylindrical body 1 side. The mounting piece part 2-1 and the connecting piece part 2-2 are bent at a substantially obtuse angle so as to be the opening / closing fulcrum P1.
[0020]
The second bent portion 10 is connected so as to be a spring fulcrum P2 that provides an appropriate clamping force (elastic force) that biases and contacts the front end side of the clip portion 1 having the ball portion 1-1 with the surface of the cylindrical body 4. It is formed by being bent into a substantially obtuse angle between the set piece 2-2 and the ring-shaped mounting portion 3.
[0021]
Thus, by attaching the attachment side portion 2-1 of the elastic portion 2 configured as described above to the back surface of the clip portion 1 by a fixing means such as spot welding, the elastic attachment provided with the ring-shaped attachment portion 3 on the other end side. The part 2 is provided on the back surface of the clip part 1.
At this time, the back surface of the clip portion 1 of the mounting piece 2-1 so that the first bent portion 9 is present on the back surface of the clip portion 1 at a position in the vicinity of approximately 1/3 of the entire length of the clip portion 1 on the rear end side of the clip portion 1. It is preferable to consider the mounting position.
[0022]
The reason for this is that, for example, the overall length L of the clip portion 1 is set to 40 mm and a holding force of 250 g is obtained, and the first bent portion 9 serving as the swing opening / closing fulcrum P1 is located on the rear end side of the clip portion 1. When it is made to exist on the back surface of the clip portion 1 at approximately ¼ portion of the entire length L of the clip portion 1, the force required to press the rear end side operation portion 5 toward the cylindrical body 4 is 875 g.
Further, the force when the first bent portion 9 is present on the back surface of the clip portion 1 at approximately 1/2 site of the entire length L of the clip portion 1 is 438 g, and the pressing force is significantly greater than that of the aforementioned approximately 1/4 site. As a result of the experiment, it was found that it became smaller (lighter). However, the presence of the first bent portion 9 at substantially half the length L of the clip portion 1 in this way means that the opening (opening) at which the front end side of the clip portion 1 is separated from the surface of the cylindrical body 4 is the aforementioned 1/4. This is because the object of the present invention such as a problem that it becomes difficult to insert into the adherend B such as a thick notebook becomes difficult.
[0023]
From these results, the force when pushing the rear end side operation part 5 of the clip part 1 to the cylinder 4 side is about 665 g, and the opening of the front end side of the clip part 1 is an adherend B such as a thick notebook. In view of the fact that an opening (opening) that can be inserted smoothly without any problem can be ensured between the ball part 1-1 of the clip part 1 and the cylindrical body 4, etc. The elastic portion 2 is formed so that the first bent portion 9 serving as the swing opening / closing fulcrum P1 is present on the back surface of the rear end side of the clip portion 1 in the vicinity of approximately 1/3 of the entire length L of the clip portion 1 on the rear end side of the clip portion 1. It has been found that it is preferable to attach to the back surface of the clip portion 1.
[0024]
Further, the contact locking of the lower end contact portion 6-1 to the surface of the cylindrical body 4 in the both support leg portions 6 of the clip portion 1 is a downward direction substantially perpendicular to the surface of the cylindrical body 4 from the first bent portion 9 described above. It is preferable to consider the bent protruding position and protruding shape from both edges of the clip portion 1 of both support legs 6 so as to be performed at the position or the rear position (the rear end side of the cylinder 4).
[0025]
Next, how to attach the clip A having the above-described configuration in detail to the cylinder 4 will be briefly described.
First, the ring-shaped mounting portion 3 provided on the other end side of the elastic portion 2 is set on the clip mounting portion 7 formed at the rear end of the cylinder 4, and then the ring-shaped mounting portion 3 is sandwiched between the clip mounting portion 7. In this way, the stopper 8 is assembled by press-fitting or screwing.
When the ring-shaped mounting portion 3 is attached to the clip mounting portion 7 by the stopper 8, the second bent portion 10 between the mounting portion 3 and the connecting piece portion 2-2 of the elastic portion 2 has a ball portion. The elastic force which makes the front end side of the clip part 1 which has 1-1 urge-contacts to the cylinder 4 surface side by appropriate clamping force arises.
[0026]
Next, the operation when using the cylinder 4 to which the clip A is attached will be described.
When the cylindrical body 4 is inserted and stored in an article to be adhered B such as a pocket of clothes or a notebook, the rear end side operation section 5 of the clip section 1 is pushed to the cylindrical body 4 side.
Then, the clip portion 1 uses the lower end contact portion 6-1 of both support legs 6 contacting the surface of the cylinder 4 as the swing support point P0, and the first bent portion 9 of the back elastic portion 2 as the swing opening / closing fulcrum P1. As shown in FIG. 3, the front end side having the ball portion 1-1 is lifted and moves away from the surface of the cylindrical body 4 so that the adherend B can be inserted (from the two-dot chain line in FIG. 3 to the solid line state).
[0027]
At this time, the clip portion 1 swings with the lower end contact portion 6-1 of both support legs 6 contacting the surface of the cylindrical body 4 as the swing support point P0, so that the ring-shaped mounting portion 3 and the second bent portion 10 are moved. Therefore, the continuous piece 2-2 that is connected to the back surface of the clip portion 1 so as to be inclined forward and upward is not distorted (dripped) from the second bent portion 10 toward the surface of the cylindrical body 4.
That is, when the clip portion 1 is pushed to push the rear end side operation portion 5 toward the cylindrical body 4 side, a stress load such as bending is not applied to the second bent portion 10 serving as the spring fulcrum P1, so the clip portion 1 The initial setting clamping force can be ensured for a long time.
[0028]
The bending shape such as the height of the support leg 5 of the clip part 2, the length of the connecting piece part 2-2, the bending of the second bent part 10 which becomes the spring fulcrum P2 of the clip part 1, or the magnitude of the bending is as follows. It is not particularly limited.
In addition, although not shown in the drawings, for attaching the elastic portion 2 to the back surface of the clip portion 1, in addition to spot welding, the attachment piece portion 2-1 is formed into an insertion piece shape having sawtooth-shaped retaining claws on both side edges. On the other hand, it is also possible to provide an attachment portion with both edges in the length direction bent inward on the back surface of the clip portion 1 and attach it by press-fitting into the attachment portion.
[0029]
Further, when the clip portion 1 is made of resin, in addition to the above-described press-fitting method, several welding projections are provided in parallel on the back surface of the clip portion 1, while the elastic portion 2 is attached to the attachment piece portion 2-1 side. The elastic portion 2 can be attached to the back surface of the clip portion 1 by an appropriate fixing means such as a welding method in which an attachment hole for penetrating the welding protrusion is provided.
[0030]
FIG. 5 shows another embodiment of the clip A-1 of the present invention.
In such an embodiment, except that the shape of the attachment portion 11 attached to the cylinder is changed from the above-described ring shape to a folded insertion piece shape described later, the same as the above-described detailed description of the embodiment, and the same components are the same. A duplicate description is omitted by attaching a reference numeral.
[0031]
That is, the mounting portion 11 attached to the cylindrical body 4 is folded back and connected substantially in parallel with the axial center of the cylindrical body 4 from the continuous piece portion 2-2 of the elastic portion 2 via the second bent portion 10. Is bent into an insertion piece that is press-fitted into an insertion hole 12 provided in the insertion hole 12, whereby the insertion piece-like attachment portion 11 and the continuous piece portion 2-2 are substantially U-shaped via the second bending portion 10. It is formed by bending into a spring shape that is continuously arranged so as to form a shape.
Needless to say, a saw blade-like retaining pawl may be provided on both edges of the insertion piece-like mounting portion 11 as required.
[0032]
The clip A-2 shown in FIG. 6 has a pair of band portions 13-1 bent in a substantially cylindrical shape from the continuous piece portion 2-2 of the elastic portion 2 to the rear so as to embrace the cylindrical body 4 from both sides. The band-shaped attachment portion 13 is provided, and the clip portion 1 can be attached to the cylinder body 4 by being fitted on the outer periphery of the rear end of the cylinder body 4.
In such an embodiment, except that the shape of the attachment portion 12 is changed to a band shape, the description is omitted basically by attaching the same reference numerals to the same components, since it is basically the same as the detailed description of the previous embodiment. To do.
[0033]
FIG. 7 shows another embodiment in which the elastic portion 2 is integrally formed from the clip portion 1 by bending.
In this embodiment, the clip A-3 is formed by bending the attachment piece 2-1 of the elastic portion 2 so as to be folded back from the rear end of the clip portion 1 toward the back surface. The clip part 1 and the elastic part 2 are integrally formed by bending the elastic part 2 provided with the part 3 on the other end side.
In this way, in this embodiment, except that the clip portion 1 and the elastic portion 2 are changed to an integrated structure, the same reference numerals are given to the same components because they are basically the same as the detailed description of the previous embodiment. The duplicated explanation is omitted.
[0034]
【The invention's effect】
Since the binder-type clip of the present invention is constructed as described above, the following effects are obtained.
Separately from the spring fulcrum P2 of the clamping force that urges and contacts the front end side of the clip portion having the ball portion to the cylindrical body surface, the front and rear swing support of the clip portion when the operation portion on the rear end side of the clip portion is pushed A clip that provides a support leg at point P0 on the clip part itself, lifts the front end side of the clip part away from the cylinder surface with the lower end contact part contacting the cylinder surface of the support leg as a swing support point P0 Since the opening operation of the portion can be performed, a load such as a bending stress at the time of the opening operation of the clip portion that pushes the operation portion toward the cylindrical body is subjected to the second of the elastic portion and the attachment portion serving as the spring fulcrum P2. Do not hang on the bend.
Therefore, the spring fulcrum P2 of the clamping force does not cause metal fatigue (elastic fatigue) due to frequent opening operation of the clip portion. Therefore, since the initial setting clamping force of the clip portion can be maintained for a long time, it is possible to provide a binder-type clip that ensures the quality stability.
[0035]
Further, the first bent portion serving as the swing opening / closing fulcrum P0 of the clip portion is made to be in the vicinity of approximately 1/3 of the entire length of the clip portion on the back surface on the rear end side of the clip portion, thereby contacting the surface of the cylindrical body. While securing the clip clamping force and the opening (opening) on the front end away from the cylinder surface when the rear end side operation unit is pressed, the rear end operation unit The pressing force can be reduced. That is, since the opening operation of the clip portion that pushes the operation portion toward the cylindrical body can be performed lightly with a small force, a binder-type clip excellent in operability and handleability can be provided.
[0036]
In addition, although it is a binder type, a mounting portion provided on the other end side of the elastic portion is conventionally used as a simple mounting structure such as crimping, external fitting or press fitting, that is, as a general metal clip mounting means. The clip portion can be attached to the cylindrical body with a simple structure such as a ring shape, a band shape consisting of a pair of band portions, or a folded insertion piece shape.
Therefore, the structure is simplified and the assembly workability is improved and the productivity is improved as compared with the conventional structure using a support shaft, a rotating shaft, and a spring material, which have difficulty in complicating and assembling the structure. As a result, it is advantageous in terms of cost.
