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向き出しで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、前者、後者何れのものもクリップ部の前端裏面に突出する玉部のみにより、つまり、該玉部と筒体との間で衣服の胸ポケットやノート等の被挾着物を挟む一点挟持構造であることから、特に滑り易い書類等に挟んで置いた場合に簡単に抜け外れてしまうことがあった。
そこで、強力なバネ材等を用いてクリップ部の挟持力を強くする等の対策が行なわれているが、玉部のみによる挟持力を強くすればするほど、当該玉部を有する前端側を開くために操作するクリップ部の後端側操作部の押圧が硬くなる。つまり、クリップ部の開操作性が悪く、取扱い性に問題があった。
【０００７】
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。
【０００８】
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。
【０００９】
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、クリップ部の前端側が筒体表面に接触する設定挟持力と被挾着物の差し込み挟持量を確保しながら、クリップ部の後端側操作部を押圧する際の操作を小さな力で可能とし、しかも、クリップ部の挟持力のバネ支点と揺動支持点とを独立させることで、クリップ部の挟持力を長期に亘り安定させて品質の保障が期待でき、また、衣服の胸ポケットやノート等の被挾着物に差し込む保管時には前後２箇所の挟持力が保障される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。
【００１０】
【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、前後部分が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から固着又は折り曲げ加工により連設する弾性部と、この弾性部の他端に一体に折り曲げ形成されて筒体に挾着又は外嵌又は圧入等により取り付けられる取付部とで構成され、
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、該取付片部から筒体表面に向けた支持片部を備えて、該支持片部と前記取付片部との間に、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、
且つ、前記支持片部から前記取付部に向けて連なる連設片部を備えて、該連設片部と前記支持片部との間に、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支持点となるように屈曲せしめた第２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３屈曲部を備えてなることにある。
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とは別途に折り曲げ製作し、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取り付ける。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取り付ける。
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。
【００１１】
また、請求項２の発明は、上記第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折り曲げ形成され、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。
【００１２】
また、請求項３の発明は、上記第２屈曲部が、クリップ部の後端側操作部を押した時に筒体表面に接触して、該クリップ部の揺動支持点となるように折り曲げ形成したことにある。
【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、曲げ加工により作製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の後方裏面にはスポット溶接等の固着手段により弾性部２が具備されている。
【００１５】
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折り曲げ加工により形成されるもので、他端側に一体に形成されて筒体４に取り付けられる取付部３との後述する第３屈曲部５がクリップ部１の挾着力のバネ支点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。
この弾性部２の一端側に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折り曲げ形成され、他端側には筒体４後端のクリップ装着部９に止め具６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、その後、筒体４の軸芯に対して略直交するように略鋭角に折り曲げ加工される取付部３が第３屈曲部５を介して形成されている。
【００１６】
また、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、後端側を同表面から離した斜め形態にてクリップ部１を保持すると共に、クリップ部１の後退側操作部８を筒体４側に押した時のクリップ部１の揺動開閉支点Ｐ０となる支持片部２−２が上記取付片部１−１から第１屈曲部１３を介して筒体４の表面に向けて略鋭角に折り曲げ形成されている。
そして、この支持片部２−２との間に第２屈曲部７を折り曲げ形成するように斜め後方に向けて傾斜状又は湾曲状で支持片部２−２から板幅が徐々に幅広状に広がり輪状取付部３に連なる第３屈曲部５を介して連設する連設片部２−３が折り曲げ加工されている。
【００１７】
第１屈曲部１３は、クリップ部１の後端側操作部８を筒体１側に押した時、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Ｐ０となるように取付片部２−１と支持片部２−２との間に略鋭角状に形成される。
【００１８】
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１３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。
【００１９】
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Ｐ０となる第１屈曲部１３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８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１３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、この様に屈曲部７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。
【００２０】
これらの結果からクリップ部１の後端側操作部８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Ｐ０となる第１屈曲部１３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。
【００２１】
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の他端に設けられている輪状取付部３を、筒体４後端のクリップ装着部９に嵌め合わせるようにセットし、その後、クリップ装着部９に輪状取付部３を挟み込むように止め具６を圧入やネジ込み方式により組み込む（図４から図５の二点鎖線の状態）。輪状取付部３が止め具６によりクリップ装着部９に取り付け挾着されると、取付部３と弾性部２の連設片部２−３との第３屈曲部５にはクリップ部１の前端側（玉部１−１）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。
【００２２】
次に、クリップＡが取り付けられた筒体４を使用する時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８を筒体４側に押す（図示矢印方向）。すると、クリップ部１は裏面弾性部２の第１屈曲部１３を揺動開閉支点Ｐ０として、玉部１−１を有する前端側を筒体４表面から持ち上げて離す動きを成し、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）。
この時、クリップ部１の後端側操作部８は筒体４表面に接触する状態まで筒体４側に接近せずに、弾性部２の連設片部２−３と輪状取付部３との第３屈曲部５上に受止められる（図３の実線の状態）。
つまり、筒体４の表面から離間盛り上がる弾性部２の第３屈曲部５はクリップ部１が必要以上に揺動開かないようにその開動作を止めるストッパーとして機能する役目を成す。これにより、筒体４への接触（衝突）を防ぐと共に、第１屈曲部１３に掛かる曲げ応力を必要最小限に抑える。
【００２３】
そして、クリップ部１の後端側操作部８を筒体４側に押す操作を取り止め、被挾着部Ｂを筒体４とクリップ部１との間に挟み込んだ後に、被挾着物Ｂを更に差し込むことで、被挾着物Ｂは図６に示すように筒体４と第２屈曲部７との間に入り込み挟持される。
つまり、クリップ部１の玉部１−１と弾性部２の第２屈曲部７との前後２箇所の挟持力により筒体４を被挾着物Ｂに挟み込み保管し得ることになる。
【００２４】
尚、弾性部２の支持片部２−２の高さＬ１や連設片部２−３の長さＬ２、そしてクリップ部１の挟持力のバネ支点Ｐ２となる第３屈曲部５の湾曲又は屈曲の大小、更に筒体４表面からの膨らみ高さＬ３等に伴う連設片部２−３の折り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２−２を両縁に鋸刃状の抜止爪等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、該取付部への取付辺部２−２の圧入により取り付けるようにするも良い。
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２−２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。
【００２５】
図７、図８は、筒体４へ取り付ける取付部の形態を変えた他の実施例を示す。
図７に示すクリップＡ−１は、筒体４を両側から抱き込むように一対の帯部１０−１を弾性部２の連設片部２−３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１０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。
【００２６】
図８に示すクリップＡ−２は、弾性部２の連設片部２−３から筒体４の軸芯と平行に折返し連設させた折返し挿入片状の取付部１１と成し、筒体４の後端に軸方向に設けられている挿入孔１２に圧入せしめることで、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、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。
斯かる図７、図８に示す実施例では取付部１０，１１の形態をバンド状や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。
【００２７】
図９は、弾性部２をクリップ部１から一体に折り曲げ形成した実施形態の一例を示す。
斯かる実施例詳述のクリップＡ−３は、弾性部２の取付片部２−１をクリップ部１の後端から裏面に添設するように一体に折り曲げ連設させた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。
【００２８】
図１０は、弾性部２の支持片部２−２と連設片部２−３との折り曲げ形態を変えて示す他の実施例である。
斯かる実施例詳述のクリップＡ−４は、支持片部２−２をクリップ部１の裏面から斜め後方に向けて突出し、この斜め支持片部２−２の傾斜下端に、クリップ部１の揺動支持点Ｐ１となる第２屈曲部７を屈曲すると共に、この屈曲部７から略逆向きＵ状を成すように連設片部２−３を湾曲連設せしめて第３屈曲部５を介して取付部３を一体に連設させてなる。
つまり、斯かる実施例詳述のクリップＡ−４は、クリップ部１の後端側操作部８を押圧した時のクリップ部１の揺動支持点Ｐ１となる第３屈曲部７の筒体１表面への接触位置を、前述の実施例詳述に比べてクリップ部１の後端側に存在させた構成にしてある。
【００２９】
図１１及び図１２は、クリップ部１の後端側操作部８を押した時にクリップ部１の揺動支持点Ｐ１となる第２屈曲部７が、同操作を行なう前では筒体４の表面から僅かに離れており、同操作が行なわれた時に筒体４の表面に接触して前後部位に揺動するクリップ部１の揺動支持点Ｐ１となるように折り曲げ形成してなる他の実施例を示す。
即ち、斯かる実施例詳述のクリップＡ−５は、前述の実施例詳述のように弾性部２の他端に設けられている輪状取付部３を介して筒体４に組み込み取り付けられた状態では弾性部２の第２屈曲部７が筒体４の表面から僅かに離れた状態と成し（図１１の状態）、クリップ部１の後端側操作部８を筒体４側に押した時に揺動支持点Ｐ１となる弾性部２の第２屈曲部７が筒体４の表面に接触するように形成してなる（図１２（ａ）及び（ｂ）の状態）。
この様に、斯かる実施例詳述ではクリップ部１の後端側操作部８を押した時に弾性部２の第２屈曲部７が筒体４の表面に接触するように形成した以外、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。
【００３０】
【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。
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とは独立させてクリップ部の後端側操作部を押した時の前後の揺動開閉支点Ｐ０となる第１屈曲部を設けて、この第１屈曲部を揺動開閉支点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３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たバインダー式のクリップを提供することができる。
【００３１】
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。
【００３２】
また、衣服の胸ポケットやノート等の被挾着物に差し込み保管時にはクリップ部の前端裏面の玉部とクリップ部の揺動支持点Ｐ１となる第２屈曲部との前後２箇所で被挾着物を挟み込む挟持力が保障されることで、特に滑り易いノート等から不用意に抜け外れることがない。
従って、筆記具や化粧品等の小物製品が不用意に脱落することがない状態で衣服の胸ポケットやノート等に挟持保管することができる。
また、この様に弾性部の第２屈曲部が筒体とにより被挾着物を挟み込む挟持機能を果たすことで、第２屈曲部が被挾着物の差し込み挟持量を規制する障害とならずにバネ支点Ｐ２となる第３屈曲部（取付部）の近くまで被挾着物を差し込んだ状態でクリップ部に確実に挟持させることができる。
【００３３】
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。

By the way, small products such as writing utensils and cosmetics greatly affect productivity and the number of lots, but in the case of the former, a support shaft is provided in the clip part, and a protruding piece is provided, and a bearing is provided on the cylindrical body side. The structure, such as providing a notch groove for forming a rebound tongue piece, becomes complicated, and it takes time and effort to process and assemble.
In addition, since the mounting of the clip portion is a structure in which the support shaft is inserted between the bearings in a bridging manner, the swinging opening and closing operation of the clip portion is frequently performed, so that the shaft insertion opening of the bearing is worn. There was also a problem in quality such as the support shaft detaching from the bearing and the clip part coming off. In addition, since the support shaft and the bearing of the clip portion are exposed to the surface of the cylindrical body in a protruding manner, the structure is not suitable for a high-quality writing instrument.
[0005]
In the latter case, the number of parts to be attached to the cylinder of the clip portion is large, the structure is complicated, and there are drawbacks such as that the assembly to the cylinder takes time and effort. In addition, since the number of parts is large and the structure is complicated, there is a problem that failures and the like also increase. Like the former, the structure is not suitable for high-quality writing instruments.
[0006]
Also, in both the former and the latter, only a ball portion protruding from the back surface of the front end of the clip portion, that is, a one-point holding structure for holding a to-be-clamped object such as a breast pocket or a notebook between the ball portion and the cylindrical body. Therefore, it may easily come off particularly when it is placed between slippery documents or the like.
Therefore, measures such as strengthening the clipping force of the clip portion using a strong spring material or the like have been taken. However, the stronger the clamping force of the ball portion alone, the more the front end side having the ball portion is opened. The operation of the rear end side operation portion of the clip portion to be operated becomes harder. That is, the opening operation of the clip portion is poor, and there is a problem in handling.
[0007]
As for the former and the latter, clips whose front end moves away from the surface of the cylinder by pressing the rear end operation section toward the cylinder are described in US Pat. No. 5,601,376 (hereinafter referred to as US) and WO99. / 42304 (PCT / EP98 / 04204) (hereinafter WO).
The clip disclosed in the U.S. Patent has a claw portion for engaging the mounting block provided on the rear end side surface of the cylindrical body so as to embrace the mounting block inward on both sides of the rear end side of the clip portion. At the end, a spring portion is provided so as to be folded toward the back surface side, and the front end side of the clip portion is always urged into contact with the surface of the cylindrical body with the engagement portion formed by the claw portion as a swing support point. Is configured.
[0008]
The clip disclosed in the WO patent has a rear end side rear surface of the clip portion, which extends from both bent edges of the clip portion, is bent inward so that mating edges approach each other, and protrudes toward the front end side of the clip portion. By inserting the inserted portion into the fixed portion provided on the rear end side of the cylindrical body by insertion, the front end of the clip portion is set with the connecting base of the inserted portion to the clip portion as a swing support point. The side is always in urge contact with the surface of the cylindrical body, and the front end side is configured to move away from the surface of the cylindrical body by pressing the curved and warped operating portion on the rear end side toward the cylindrical side.
[0009]
The present invention has been made in view of such a conventional situation, and its purpose is to secure a set clamping force at which the front end side of the clip portion contacts the surface of the cylindrical body and an insertion clamping amount of a clamped object. The operation when pressing the rear end side operation part of the clip part can be performed with a small force, and the clip support force of the clip part is independent of the spring fulcrum and the swing support point of the clip part, so that the clamping force of the clip part can be extended for a long time. It can be expected to guarantee quality by stabilizing for a long time, and it is effective for small articles such as writing utensils and cosmetics, which guarantees two front and rear clamping forces when stored in clothes such as breast pockets and notebooks. It is to provide a binder type clip.
[0010]

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 member that is axially clamped so as to be sandwiched by a stopper that is press-fitted or screwed into the rear end of the cylindrical body, a cylindrical shape that is fitted around the rear end of the cylindrical body and attached by external fitting, A band-shaped member consisting of a pair of band portions, or a folded insertion piece having a saw blade-shaped retaining claw on both edges and attached by press-fitting to an insertion hole provided in the rear end of the cylindrical body in the axial direction. And the like.
[0011]
Further, the invention according to claim 2 is characterized in that the first bent portion swings and opens when the rear end side operation portion of the clip portion is pressed at a position near substantially one third of the entire length of the clip portion on the rear surface on the rear end side of the clip portion. It is bent and formed so as to serve as a fulcrum, so that the opening operation of the front end side of pressing the rear end side operation portion of the clip portion toward the cylindrical body can be performed lightly with a small force.
[0012]
Further, the invention according to claim 3 is characterized in that the second bent portion is bent so as to come into contact with the surface of the cylindrical body when the rear end side operation portion of the clip portion is pressed, so as to be a swing support point of the clip portion. I did it.
[0013]
BEST MODE FOR CARRYING OUT THE INVENTION
Embodiments 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, wherein 1 is a clip portion, 2 is an elastic portion, 3 is an attachment portion which is attached to the cylinder 4 by clamping, external fitting or press fitting. Reference numeral 4 denotes a main body of a small product that can be carried, such as a barrel for a writing instrument or a makeup tool, a cap, or the like.
[0014]
The clip portion 1 is formed by bending using a metal plate or by molding using a molten metal material or a synthetic resin material. The drawing shows an example made of metal manufactured by a series of punching and bending processes using a metal plate.
A ball portion 1-1 is formed on the back surface of the front end of the clip portion 1 (the surface facing the cylindrical body 4) by bending, and the elastic portion 2 is formed on the back surface of the back portion of the ball portion 1-1 by fixing means such as spot welding. Is provided.
[0015]
The elastic portion 2 is formed by bending a desired metal plate having an appropriate rigidity and excellent spring properties. The elastic portion 2 is integrally formed on the other end side, and will be described later. The third bent portion 5 serves as a spring fulcrum P2 of the clamping force of the clip portion 1, and is formed such that the front end side of the clip portion 1 is always in urge contact with the surface of the cylindrical body 4.
An attachment piece 2-1 fixedly attached to the back surface of the clip portion 1 on one end side of the elastic portion 2 by a fixing means such as spot welding or the like follows the same back surface shape with a width enough to fit on the back surface. The other end side is punched into a ring shape (ring shape) which is axially inserted into the clip mounting portion 9 at the rear end of the cylindrical body 4 by the stopper 6. A mounting portion 3 that is bent at a substantially acute angle so as to be substantially perpendicular to the mounting portion 3 is formed via a third bent portion 5.
[0016]
Further, the front end side of the clip portion 1 having the ball portion 1-1 is brought into urging contact with the surface of the cylindrical body 4 and the clip portion 1 is held in an oblique shape with the rear end side separated from the surface, and The support piece 2-2 serving as the pivotal opening / closing fulcrum P0 of the clip portion 1 when the retreat-side operation portion 8 is pushed toward the cylindrical body 4 from the mounting piece 1-1 via the first bent portion 13. It is bent at a substantially acute angle toward the surface of the cylinder 4.
Then, the plate width is gradually increased from the support piece 2-2 in an inclined or curved shape obliquely rearward so as to bend and form the second bent portion 7 with the support piece 2-2. The connecting piece 2-3 continuously provided via the third bent portion 5 connected to the expanding annular mounting portion 3 is bent.
[0017]
The first bent portion 13 is configured such that when the rear end side operation portion 8 of the clip portion 1 is pushed toward the cylinder 1 side, the front end side of the clip portion 1 becomes a swing open / close fulcrum P0 when separating from the surface of the cylinder 4. A substantially acute angle is formed between the mounting piece 2-1 and the support piece 2-2.
[0018]
Thus, by attaching the attachment side 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 or the like, the elastic portion having the annular attachment portion 3 on the other end side is provided. A portion 2 is provided on the back surface of the clip portion 1.
At this time, the back surface of the clip portion 1 of the mounting piece portion 2-1 so that the first bent portion 13 is present on the back surface of the clip portion 1 at a position near the rear end side of the clip portion 1 in the vicinity of approximately 1/3 of the entire length of the clip portion 1. It is preferable to consider the mounting position on the device.
[0019]
The reason for this is that, for example, the total length L of the clip portion 1 is set to 40 mm, and a clamping force of 250 g is obtained, and the first bent portion 13 serving as the swing open / close fulcrum P0 is located at the rear end side of the clip portion 1. When the clip portion 1 is present on the back surface of the clip portion 1 at approximately 1/4 of the entire length L, the force required to press the rear end operation portion 8 toward the cylinder 4 is 875 g.
In addition, when the first bent portion 13 is present on the back surface of the clip portion 1 at approximately half of the entire length L of the clip portion 1, the force is 438 g, and the pressing force is significantly greater than that of the approximately 1/4 portion described above. Experiments have shown that it becomes smaller (lighter).
However, the presence of the bent portion 7 at approximately one-half of the entire length L of the clip portion 1 as described above 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 greater than the above-described quarter. The reason for this is that the object of the present invention cannot be achieved, for example, it becomes considerably small, and there is a problem that it becomes difficult to insert the object into the object B such as a thick notebook.
[0020]
From these results, the force when pushing the rear end side operation portion 8 of the clip portion 1 toward the cylindrical body 4 is about 665 g, and the front end side of the clip portion 1 is opened by a thick object such as a notebook. In view of the fact that an opening (opening) allowing smooth insertion without any problem can be secured between the ball portion 1-1 of the clip portion 1 and the cylindrical body 4, etc., the clip portion 1 The first bent portion 13 serving as the swing open / close fulcrum P0 is formed on the elastic portion 2 such that the first bent portion 13 is located on the rear end side of the clip portion 1 near 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. It was found that it was preferable to attach and provide the
[0021]
Next, a brief description will be given of a method of attaching the clip A configured as described above to the cylindrical body 4 described in detail in this embodiment.
First, the ring-shaped mounting portion 3 provided at the other end of the elastic portion 2 is set so as to be fitted to the clip mounting portion 9 at the rear end of the cylindrical body 4, and then the ring-shaped mounting portion 3 is sandwiched between the clip mounting portions 9. The stopper 6 is assembled by press-fitting or screwing as described above (the state shown by the two-dot chain line in FIGS. 4 and 5). When the ring-shaped mounting portion 3 is attached and clamped to the clip mounting portion 9 by the stopper 6, the front end of the clip portion 1 is attached to the third bent portion 5 of the mounting portion 3 and the continuous piece 2-3 of the elastic portion 2. A resilient force is generated to bring the side (ball portion 1-1) into urging contact with the surface of the cylindrical body 4 with an appropriate pinching force.
[0022]
Next, an operation when the cylinder 4 to which the clip A is attached is used will be described.
When the cylinder 4 is to be inserted and stored in an object B such as a clothing pocket or a notebook, the rear end side operation unit 8 of the clip unit 1 is pushed toward the cylinder 4 (in the direction of the arrow in the figure). Then, the clip portion 1 moves the front end side having the ball portion 1-1 up and away from the surface of the cylindrical body 4 with the first bent portion 13 of the back surface elastic portion 2 as the swing open / close fulcrum P0. B becomes an open state in which B can be inserted (the state shown by the solid line from the two-dot chain line in FIG. 3).
At this time, the rear end side operation portion 8 of the clip portion 1 does not approach the cylinder 4 side until it comes into contact with the surface of the cylinder 4, and the connecting piece 2-3 of the elastic portion 2 and the ring-shaped mounting portion 3 (The state shown by the solid line in FIG. 3).
That is, the third bent portion 5 of the elastic portion 2 which rises away from the surface of the cylindrical body 4 functions as a stopper for stopping the opening operation so that the clip portion 1 does not swing and open more than necessary. This prevents contact (collision) with the cylindrical body 4 and minimizes the bending stress applied to the first bent portion 13 to a necessary minimum.
[0023]
Then, the operation of pushing the rear end side operation portion 8 of the clip portion 1 toward the cylinder 4 is stopped, and the clamped portion B is sandwiched between the cylinder 4 and the clip portion 1. By being inserted, the object B is inserted between the cylindrical body 4 and the second bent portion 7 as shown in FIG.
In other words, the cylindrical body 4 can be sandwiched and stored by the clamping force at the front and rear two places between the ball portion 1-1 of the clip portion 1 and the second bent portion 7 of the elastic portion 2.
[0024]
The height L1 of the support piece 2-2 of the elastic part 2, the length L2 of the connection piece 2-3, and the bending or bending of the third bent portion 5 serving as a spring fulcrum P2 of the clamping force of the clip portion 1. The bending shape of the connecting piece 2-3 according to the magnitude of the bending and the bulging height L3 from the surface of the cylindrical body 4 and the like are not particularly limited.
Although not shown in the drawings, in addition to spot welding, the elastic piece 2 is attached to the back surface of the clip part 1 by using an insert piece having a saw-like retaining claw or the like on both sides of the attachment piece part 2-2. On the other hand, the clip portion 1 is provided with a mounting portion formed by bending both edges in the longitudinal direction inward on the back surface, and the clip portion 1 is mounted by press-fitting the mounting side portion 2-2 into the mounting portion. good.
When the clip portion 1 is made of resin, in addition to the above-described press-fitting method, several welding projections are provided side by side on the back surface of the clip portion 1, while the welding protrusions are provided on the mounting piece portion 2-2 side of the elastic portion 2. 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 is provided through the welding projection.
[0025]
FIGS. 7 and 8 show another embodiment in which the form of the mounting portion to be attached to the cylinder 4 is changed.
A clip A-1 shown in FIG. 7 is formed by bending a pair of band portions 10-1 rearward from a continuous piece 2-3 of the elastic portion 2 in a substantially cylindrical shape so as to embrace the cylindrical body 4 from both sides. The clip portion 1 can be attached to the cylindrical body 4 by forming the band-shaped mounting portion 10 and externally fitting the outer periphery of the rear end of the cylindrical body 4.
[0026]
A clip A-2 shown in FIG. 8 is a folded insertion piece-shaped mounting portion 11 that is continuously folded from the continuous piece 2-3 of the elastic portion 2 in parallel with the axis of the cylindrical body 4, The clip portion 1 can be attached to the cylindrical body 4 by being pressed into an insertion hole 12 provided at the rear end of the cylinder 4 in the axial direction.
It is needless to say that both edges of the mounting portion 11 may be provided with saw-shaped retaining claws as necessary.
In the embodiment shown in FIGS. 7 and 8, except that the form of the mounting portions 10 and 11 is changed to a band shape or a folded insertion piece shape, it is basically the same as the above-mentioned detailed description of the embodiment. The same reference numerals are given to omit redundant description.
[0027]
FIG. 9 shows an example of an embodiment in which the elastic portion 2 is integrally bent from the clip portion 1.
The clip A-3 described in detail in the embodiment is changed to an integrated structure in which the mounting piece 2-1 of the elastic portion 2 is integrally bent and connected from the rear end of the clip portion 1 to the back surface. Other than the above, since the configuration is basically the same as that of the above-described embodiment, the same components are denoted by the same reference numerals, and a duplicate description is omitted.
[0028]
FIG. 10 shows another embodiment in which the bent form of the support piece 2-2 and the continuous piece 2-3 of the elastic part 2 is changed.
In the clip A-4 described in detail in this embodiment, the support piece 2-2 protrudes obliquely rearward from the back surface of the clip part 1, and the lower end of the oblique support piece 2-2 is The second bent portion 7 serving as the swing support point P1 is bent, and the connecting piece 2-3 is curved and connected so as to form a substantially U-shaped direction from the bent portion 7, thereby forming the third bent portion 5. The mounting portion 3 is integrally and continuously provided via the intermediary.
In other words, the clip A-4 described in detail in the embodiment is the cylindrical body 1 of the third bent portion 7 which becomes the swing support point P1 of the clip portion 1 when the rear end operation portion 8 of the clip portion 1 is pressed. The configuration is such that the contact position on the surface is located on the rear end side of the clip portion 1 as compared with the detailed description of the above-described embodiment.
[0029]
FIG. 11 and FIG. 12 show that the second bent portion 7 serving as the swing support point P1 of the clip portion 1 when the rear end side operation portion 8 of the clip portion 1 is pressed, has a surface of the cylindrical body 4 before performing the same operation. And is formed so as to be a pivot support point P1 of the clip portion 1 which contacts the surface of the cylindrical body 4 and pivots forward and backward when the same operation is performed. Here is an example.
That is, the clip A-5 described in detail in this embodiment is assembled and attached to the cylindrical body 4 via the ring-shaped attachment portion 3 provided at the other end of the elastic portion 2 as described in detail in the previous embodiment. In the state, the second bent portion 7 of the elastic portion 2 is slightly separated from the surface of the cylinder 4 (the state shown in FIG. 11), and the rear end side operation portion 8 of the clip portion 1 is pushed toward the cylinder 4. The second bent portion 7 of the elastic portion 2 which becomes the swing support point P1 when it comes into contact with the surface of the cylindrical body 4 is formed (the state shown in FIGS. 12A and 12B).
As described above, in the detailed description of the embodiment, except that the second bent portion 7 of the elastic portion 2 is formed so as to contact the surface of the cylindrical body 4 when the rear end operation portion 8 of the clip portion 1 is pressed. Since the details are basically the same as those of the first embodiment, the same components are denoted by the same reference numerals, and redundant description will be omitted.
[0030]
【The invention's effect】
Since the binder-type clip of the present invention is configured as described above, the following operational effects can be obtained.
A first bend that becomes a swinging opening / closing fulcrum P0 before and after pressing a rear end side operation part of the clip part independently of a spring fulcrum P2 of a holding force for urging the front end side of the clip part into contact with the surface of the cylindrical body. The first bent portion is provided as a swing opening / closing fulcrum P0 so that the front end side of the clip portion can be opened and lifted from the surface of the cylindrical body so that the clip portion can be opened. A load such as a bending stress at the time of the opening operation of the clip portion pushed toward the cylindrical body is not applied to the third bent portion between the elastic portion serving as the spring fulcrum P2 and the mounting portion.
Therefore, the spring fulcrum P2 of the holding force does not cause metal fatigue (elastic fatigue) due to frequent opening operation of the clip portion. Therefore, a binder-type clip in which the stability of quality is ensured can be provided by maintaining the initial setting clamping force of the clip portion for a long period of time.
[0031]
In addition, the first bent portion serving as the pivoting opening / closing fulcrum P0 of the clip portion is provided at a position in the vicinity of approximately 1/3 of the entire length of the clip portion on the rear surface on the rear end side of the clip portion, thereby contacting the surface of the cylindrical body. While securing the clipping force of the clip portion and the opening (opening) of the front end side that separates from the surface of the cylinder when the rear end side operation part is pressed, the rear end side operation part is secured without interfering with insertion into the object to be clamped. Pressing force can be reduced. In other words, a binder-type clip excellent in operability and handleability can be provided because the opening operation of the clip portion for pushing the operating portion toward the cylinder can be performed lightly with a small force.
[0032]
In addition, during insertion and storage in a clothes pocket such as a breast pocket or a notebook, the clothes are held at two positions before and after a ball portion on the back surface of the front end of the clip portion and a second bent portion serving as a swing support point P1 of the clip portion. Since the pinching force for pinching is ensured, careless removal from a slippery notebook or the like does not occur.
Therefore, small articles such as writing utensils and cosmetics can be held and stored in breast pockets or notebooks of clothes without being inadvertently falling off.
In addition, since the second bent portion of the elastic portion has a function of holding the object to be clamped by the cylindrical body, the second bent portion does not hinder the insertion and holding of the object to be clamped. The clip can be reliably clamped in a state where the clamped object is inserted close to the third bent portion (mounting portion) serving as the fulcrum P2.
[0033]
In addition, despite being of the binder type, the mounting portion provided on the other end side of the elastic portion has been conventionally adopted as a simple mounting structure such as clamping, external fitting or press fitting, that is, a general metal clip mounting means. The clip portion can be attached to the cylindrical body by a simple structure such as a ring shape, a band shape including a pair of band portions, or a folded insert piece shape.
Therefore, the structure is simplified, the assembly workability is extremely simple, and the productivity is improved, as compared with the conventional structure using a support shaft and a rotating shaft, which are difficult to assemble, and a spring material. Can be expected, and it is also advantageous in terms of cost.
