Description

【０００１】
【発明の属する技術分野】
本発明は、携帯電話のストラップやサスペンダ等に取り付けて使用するクリップに関する。
【０００２】
【従来の技術】
特許公報第２７０４６９７号（以下単に公報という）には、下部挟持板と上部挟持板の先端部が操作板の回動操作により開閉するプラスチック製のクリップが開示されている（図８参照）。このクリップは、上記公報の段落番号００１５〜００１６に記載されるように、
「ヒンジ（１４），（１４）の中間部は前記下部挟持板（１）の後部中央の庇部（８）が対応して嵌まる窪み（１５）になっており、この窪み（１５）の上面は後方部が高い山状を呈しており、この山状の頂面とヒンジ（１４）の内方下端間の垂直寸法Ｌは、前記下部挟持板後部の庇部（８）の下面と支持棚（６）の上面間の垂直寸法Ｍより少し大きく形成されている。従って、上部挟持板（１０）の後部を下部挟持板（１）の架橋板（４）の前方下方からくぐらせて（図８参照）のようにヒンジ（１４），（１４）の下面を支持棚（６），（６）の上面に載せるように組み込むと、上記寸法（Ｌ）と（Ｍ）の差により上部挟持板（１０）後方上端部の窪み（１５）の山状の頂面が、下部挟持板（１）後部の庇部（８）の下面により押圧されることになるので、ヒンジ下面の前下がりの斜面（１３）の後方と支持棚（６）との間隙が逃げとなってヒンジが後向きに傾き、上部挟持板（１０）の先端が開いた状態に維持される。」
という構成及び作用を有し、これによりクリップ先端部を常時開口させるのに必要な金属製のばねを省略できるようにしたものである。
【０００３】
【発明が解決しようとする課題】
しかしながら、公報の段落番号００１９に
「上部挟持板（１０）後部の補助板（１２）の後端部を下部挟持板（１）の架橋板（４）の下に前方から差し込み、操作板（２０）のアーム（２１）を垂直にして作動カム（２４）を下部挟持板（１）の後方から、補助板（１２）と架橋板（４）の間に挟み込むように差し入れた状態で上部挟持板（１０）後端の両ヒンジ（１４），（１４）の下面を支持棚（６），（６）の上部に乗せるように嵌め込む。このときアーム（２１），（２１）の上端広幅部も同時に側壁（３），（３）内面のヌスミ（９），（９）に嵌まる。上記の嵌め込み時には大きな抵抗があるが、ヒンジ（１４）の内側上部が、支持棚（６）の後方下部の斜面（１６）を滑りながらプラスチックの弾力が作用して支持棚（６）の上面にヒンジ（１４）が嵌まり込む。」
と記載されるように、上記した寸法差（Ｌ），（Ｍ）を有する下部挟持板（１）と上部挟持板（１０）の組み立ては、嵌め込み時の大きな抵抗に抗する大きな力で行わなければならないという問題点がある。
尚、上記括弧内の符号は、上記特許公報記載のものである。
本発明は上記問題点を解決するためになされたもので、組み立て作業が簡単に行えるとともに、使い勝手のよいクリップを提供することを目的とする。
【０００４】
【課題を解決するための手段】
上記目的を達成するための請求項１に記載のクリップは、後端部をそれぞれ略Ｕ字形のバネにより把持することにより先端部に形成した挟持部が互いに離間する一対の合成樹脂製クリップ片と、前記後端部と先端部を接続している前記両クリップ片の中間部の対向間隔内に挿通したカム軸を有する合成樹脂製操作レバーとから成るクリップであって、前記操作レバーは略０゜と１８０゜間を回動するものであり、前記操作レバーの略９０゜の位置で前記カム軸が前記両中間部の対向間隔を拡開して両挟持部を接合し、前記操作レバーの略９０゜の位置より略０゜または１８０゜の方向に該レバーを回動することにより、前記両挟持部が互いに離間するとともに、該操作レバーは、前記カム軸と、該カム軸の両端部に取り付けられた軸承板と、該軸承板の先端面と対向する端部に形成された取っ手部とで構成されており、前記両挟持部の接合時に、前記軸承板の先端面が前記クリップ片の一方と面同士で当接可能に、かつ、前記取っ手部の一部が前記バネと当接可能に構成され、前記バネは、前記両クリップ片の両後端部を収納する収納凹部と、該両後端部を把持してバネ力を付与する係止爪と、該両後端部の両側部を覆うサイド固定カバー部で構成され、該バネを前記両後端部に嵌め込むことで組み立てられるようになっていることを特徴とする。

【００１２】
また、請求項５に記載のクリップは、請求項４に記載の構成において、前記各挟持部の挟持面どうしを合着させた挟持状態に保持したとき、前記各クリップ片の挟持部の後端面と、前記略Ｌ字形部及び略逆Ｌ字形部の前端面とを対向させ、各挟持部を拡開する力が作用したとき、前記後端面と前端面が当接して、該挟持部の拡開を阻止することを特徴とする。
【００１３】
請求項６に記載のクリップは、請求項４又は請求項５に記載の構成において、前記操作レバーは、前記略Ｌ字形部の後方延長部側若しくは前記略逆Ｌ字形部の後方延長側に回動した何れの状態からでも、後方へ倒して前記各挟持部の挟持面どうしを合着させた挟持状態に保持できるようにすることを特徴とする。
【００１４】
【発明の作用及び効果】
【００１５】
請求項１に記載のクリップによれば、クリップの両後端部をバネで把持させるだけで両挟持部の解放力が与えられるので組立が容易に行え、しかも両挟持部の離間が操作レバーの２方向で可能であるので使い勝手がよいばかりか、一対のクリップ片に対し、両挟持部の解放力の付与と位置決め作用を一つのバネで与えることができる。また、軸承板とクリップ片との面同士の当接により、両挟持部の接合状態を確実に保持できるとともに、取っ手により操作性が向上し、且つ、合成樹脂の可撓性を利用して、両挟持部の接合状態を更に確実に保持できる。
【００１７】
請求項２に記載のクリップによれば、両挟持部の接合を解放するときは、クリップ片がその後端部で円滑に回動できる。
【００２１】
請求項３に記載のクリップによれば、バネ、両クリップ片及び操作レバーが合成樹脂製であるから、体の一部に触れても傷つく心配がなく、安全であり、且つ透明感をもたせたり着色したものも容易に製作できる。
【００２２】
請求項４に記載のクリップによれば、先端の係止爪を回動部及び支承部よりも前方に設けた各バネ掛止溝に掛止する略Ｕ字形の合成樹脂製バネのバネ力により、略Ｌ字形部の後方延長部と略逆Ｌ字形部の後方延長部の対向間隔を狭めて、先端部の挟持部どうしの対向間隔を拡開している。この状態で操作レバーを後方に倒すと、カム軸が回動して、略Ｌ字形部と略逆Ｌ字形部の各後方延長部間を合成樹脂製バネのバネ力に抗して拡開するとともに、該カム軸を少なくとも各後方延長の何れか一方の内面に形成した係合保持部に係合して、各挟持部の挟持面どうしを合着させた挟持状態に保持する。このクリップは、他方のクリップ片の略逆Ｌ字形部に開口を形成し、該開口に一方のクリップ片の略Ｌ字形部の後方延長部を挿通し、対向する後方延長部間に操作レバーのカム軸を差し渡すとともに、支承部で回動部を支承した状態で、略Ｕ字形の合成樹脂製バネを各後方延長部の後端から嵌め込んで組み立てるものであるから、組み立て作業が簡単に行える。また、軸承板とクリップ片との面同士の当接により、両挟持部の挟持面どうしを合着させた挟持状態を確実に保持できるとともに、取っ手により操作性が向上し、且つ、合成樹脂の可撓性を利用して、両挟持部の接合状態を更に確実に保持できる。
【００２３】
また、請求項５に記載のクリップによれば、各挟持部の挟持面どうしを合着させた挟持状態に保持したときに、各挟持部を拡開する力が作用すると、対向する各クリップ片の挟持部の後端面と略Ｌ字形部及び略逆Ｌ字形部の前端面とが当接して、該挟持部の拡開を阻止する。従って、被挟持部が急激に引っ張られて各挟持部を拡開する力が作用しても、被挟持物が外れてしまうことがない。
【００２４】
請求項６に記載のクリップによれば、操作レバーは、略Ｌ字形部の後方延長部側若しくは略逆Ｌ字形部の後方延長側に回動した何れの状態からでも、後方へ倒して各挟持部の挟持面どうしを合着させた挟持状態に保持できる。従って、操作レバーの操作方向に制限がないから使い勝手が向上する。
【００２５】
【発明の実施の形態】
本発明の実施形態について添付図面を参照して説明する。図１は一方のクリップ片１の断面図、図２は他方のクリップ片２１の断面図、図３（ａ）は合成樹脂製バネ１８の斜視図で、（ｂ）は同、変形例、（ｃ）はその他の変形例であり、図４は組み立て状態の平面図、図５は同、断面図、図６は操作レバーを倒した状態の平面図、図７は同、断面図である。
【００２６】
図１に示すように一方のクリップ片（以下単にクリップ片という）１は合成樹脂製であって、挟持部２の先端下面に挟持面３が形成され、後述する他方のクリップ片２１の挟持歯２４を受ける溝４と一対の挟持歯５が形成されている。挟持部２の後端面２ａが形成された中央部には、該挟持部２よりも狭い幅寸法の略Ｌ字形部６が連続して形成されている。該略Ｌ字形部６には後方延長部７（クリップ片の中間部）が形成され、その後端部の幅方向の中央部にバネ掛け用凹部８が形成されている。
【００２７】
また、該バネ掛け用凹部８に連続して、円弧状に突出する回動部９が幅方向に形成されている。バネ掛け用凹部８内には、回動部９よりも先端方にバネ掛止溝１０が幅方向に形成されている。そして、バネ掛け用凹部８の幅方向両側に、後述する略Ｕ字形のバネ１８のサイド固定カバー部１８ａが嵌まる嵌装部８ａが形成されている。さらに、後方延長部７の内面には、谷状の係合保持部１１を有する滑動面１２が形成されている。
【００２８】
バネ１８は金属製のものであってもよいし合成樹脂製のものでもよいが、合成樹脂製のものであれば、たとえ体の一部に触れることがあっても、傷つく心配がなく、安全であり、且つ透明感をもたせたり着色したものも容易に製作できる。
【００２９】
図２に示すように他方のクリップ片（以下単にクリップ片という）２１は合成樹脂製であって、挟持部２２の先端上面に挟持面２３が形成されて、一個の挟持歯２４と、上記クリップ片１の挟持歯５を受ける一対の溝２５が形成されている。挟持部２２の後端面２２ａが形成された中央部には、略逆Ｌ字形部２６が連続して形成されている。該略逆Ｌ字形部２６には、上記クリップ片１の略Ｌ字形部６の後方延長部７を緩やかに挿通する開口２７が形成されている。
【００３０】
そして、略逆Ｌ字形部２６にも、前記後方延長部７の幅寸法に合わせた後方延長部２８（クリップ片の中間部）が形成され、その後端部の幅方向の中央部にバネ掛け用凹部２９が形成されている。また、該バネ掛け用凹部２９に連続して、上記回動部９を支承する支承部３０が幅方向に形成されている。後方延長端２８のバネ掛け用凹部２９内には、支承部３０よりも先端方にバネ掛止溝３１が幅方向に形成されている。
【００３１】
さらに、バネ掛け用凹部２９の幅方向両側に、バネ１８のサイド固定カバー部１８ａが嵌まる嵌装部２９ａが形成されている。このサイド固定カバー部１８ａは両クリップ片１，２１の位置ズレを防止する位置決め作用を有している。後方延長部２８の内面には、谷状の係合保持部３２を有する滑動面３３が形成されている。
【００３２】
図３（ａ）に示すように、略Ｕ字形のバネ１８は、先端のバネ力作用部に掛止爪１９が形成されるとともに、幅方向両側にクリップ片１及び２１の後端部の嵌装部８ａ，２９ａに嵌まって、該後端及び側面を覆うサイド固定カバー部１８ａが形成されている。そして係止爪１９、サイド固定カバー部１８ａは共に両クリップ片１及び２１の後端部を収容できるような収容凹部１８ｂが形成されている。
【００３３】
また、このバネの変形例が図３（ｂ）に示してある。バネ１８’は、係止爪１９’が上下全面に広がっており、サイドを固定する部分１８’ａが板バネで構成されており、両クリップ片１及び２１の後端部を外側から付勢してその移動を拘束するようになっている。
【００３４】
更に、このバネの変形例が図３（ｃ）に示してある。バネ１８”は、上下の係止爪１９”が複数形成されていて所要の押圧力を得るようにしている。
【００３５】
また、図４〜図７に示すように操作レバー１３は合成樹脂製であって、操作用の取っ手１４に、上記クリップ片１，２１の後方延長部７及び後方延長部２８の両側で後方へ回動する軸承板１５，１５が形成されている。該軸承板１５，１５間には、断面略五角形のカム軸１６が差し渡されている。また、取っ手１４には、一側面に切り込み１４ａを設けた係止孔１７が形成されている。係止孔１７には、切り込み１４ａから扁平なストラップ等を挿し込んで係止する。
【００３６】
上記クリップ片１は、略Ｌ字形部６の後方延長部７を、クリップ片２１の略逆Ｌ字形部２６に設けた開口２７に挿通する。そして、後方延長部７と２８の対向間隔内に、操作レバー１３のカム軸１６を挿通して、後端の回動部９をクリップ片２１の支承部３０で支承し、該クリップ片１の挟持部２をクリップ片２１の挟持部２２に対して接離可能に組み合わせる。
【００３７】
そして、略Ｌ字形部６の後方延長部７と略逆Ｌ字形部２６の後方延長部２８の後端から、バネ掛け用凹部８及び２９に略Ｕ字形のバネ１８を嵌め込んで、先端の掛止爪１９をそれぞれバネ掛止溝１０及び３１に掛止する。このとき、サイド固定カバー部１８ａがクリップ片１及び２１の後端部の嵌装部８ａ及び２９ａに嵌まって該後端及び側面を覆う。これにより、クリップＣが組み立てられる。
【００３８】
上記構成のクリップＣは、取っ手１４の係止孔１７に携帯電話のストラップ（図示せず）等を係止して使用するもので、図４及び図５に示すように操作レバー１３が起立した状態では、略Ｕ字形のバネ１８のバネ力が回動部９及び支承部３０よりも先端方に作用するから、略Ｌ字形部６の後方延長部７と略逆Ｌ字形部２６の後方延長部２８の対向間隔が狭まる。従って、クリップ片１及び２１の先端部の挟持面３及び２３間が拡開する。操作レバー１３の位置が図５で示す位置から１８０゜反転した位置においても同様にクリップ片１及び２１の先端部の挟持面３及び２３間が拡開する。
【００３９】
また、図６及び図７に示すように操作レバー１３を後方へ倒すと（図５の操作レバー１３位置から略９０゜回転させると）、カム軸１６が回動して後方延長部７及び２８の内面の滑動面１２及び３３を滑動し、後方延長部７及び２８間をバネ１８のバネ力に抗して拡開する。そして、略五角形断面のカム軸１６の角部が、後方延長部６の谷状の係合保持部１１と、後方延長部２８の谷状の係合保持部３２に係合して、挟持押圧面３及び２３どうしを合着させ、挟持歯５及び２４が溝４及び２５に嵌まり込んだ挟持状態に保持される。
【００４０】
このとき図６に示すように、軸承板１５の先端面１５ａが他方のクリップ片２１の略逆字Ｌ字形部２６の後背面２６ｂと面接合するので、操作レバー１３に多少の外力が作用しても、その回動は拘束されることになる。更にこの場合、取っ手１４の一部１４ｂがカム軸１６と平行に延びていて、略Ｕ字形のバネ１８の背面と弾性変形しながら当接しているため、操作レバー１３の移動拘束はより確実なものとなる。
【００４１】
操作レバー１３は、図４及び図５に示した略Ｌ字形部６の後方延長部７側に倒立した状態のみならず、略逆Ｌ字形部２６の後方延長部２８側に起立した状態からでも、後方へ倒してクリップＣを上記挟持状態に保持できる。また、クリップＣの挟持状態を解除する場合には、後方に倒れた操作レバー１３を後方延長部７側のみならず後方延長部２８側の何れにも回動させることができる。従って、操作レバー１３の操作方向に制限がないから使い勝手が向上する。
【００４２】
上記したように、クリップＣは、クリップ片２１の略逆Ｌ字形部２６に開口２７を形成し、該開口２７にクリップ片１の略Ｌ字形部６の後方延長部７を挿通し、対向する後方延長部７及び２８間に操作レバー１３のカム軸１６を挿通するとともに、支承部３０で回動部９を支承した状態で、略Ｕ字形のバネ１８を各後方延長部７及び２８の後端から嵌め込んで組み立てるものであるから、組み立て作業が簡単に行える。
【００４３】
また、各クリップ片１，２１は、挟持押圧面３及び２３どうしを合着させるとともに、挟持歯５及び２４が溝４及び２５に嵌まり込んだ状態に保持されたとき、挟持部２の後端面２ａと、略逆Ｌ字形部２６の前端面２６ａとが対向し、挟持部２２の後端面２２ａと、略Ｌ字形部６の前端面６ａとが対向するように形成されている。従って、被挟持物（図示せず）が急激に引っ張られて、クリップ片１，２１の先端部の挟持部２若しくは２２を拡開する力が作用しても、対向する後端面２ａと前端面２６ａとが、若しくは対向する後端面２２ａと前端面６ａとが当接して挟持部２若しくは２２の拡開が阻止され、被挟持物の脱落を防止できる。

[0034]
Further, a modification of this spring is shown in FIG. The spring 18 ″ is formed with a plurality of upper and lower locking claws 19 ″ so as to obtain a required pressing force.
[0035]
4 to 7, the operation lever 13 is made of a synthetic resin, and is moved backward on both sides of the rear extension 7 and the rear extension 28 of the clip pieces 1 and 21 to the handle 14 for operation. Rotating bearing plates 15, 15 are formed. A cam shaft 16 having a substantially pentagonal cross section is provided between the bearing plates 15 and 15. The handle 14 is formed with a locking hole 17 having a cut 14a on one side. A flat strap or the like is inserted into the locking hole 17 from the notch 14a and locked.
[0036]
In the clip piece 1, the rear extension 7 of the substantially L-shaped portion 6 is inserted into an opening 27 provided in the substantially inverted L-shaped portion 26 of the clip piece 21. Then, the cam shaft 16 of the operating lever 13 is inserted into the facing interval between the rear extension portions 7 and 28, and the rotating portion 9 at the rear end is supported by the support portion 30 of the clip piece 21. The clamping part 2 is combined with the clamping part 22 of the clip piece 21 so as to be able to contact and separate.
[0037]
Then, from the rear end of the rear extension 7 of the substantially L-shaped part 6 and the rear end of the rear extension 28 of the substantially inverted L-shaped part 26, a substantially U-shaped spring 18 is fitted into the spring hooking recesses 8 and 29, The latching claw 19 is latched in the spring latching grooves 10 and 31, respectively. At this time, the side fixed cover portion 18a is fitted into the fitting portions 8a and 29a at the rear end portions of the clip pieces 1 and 21 to cover the rear end and the side surfaces. Thereby, the clip C is assembled.
[0038]
The clip C having the above structure is used by locking a mobile phone strap (not shown) or the like in the locking hole 17 of the handle 14, and the operation lever 13 is raised as shown in FIGS. 4 and 5. In the state, since the spring force of the substantially U-shaped spring 18 acts on the distal end side rather than the rotating portion 9 and the support portion 30, the rear extension portion 7 of the substantially L-shaped portion 6 and the rearward extension of the substantially inverted L-shaped portion 26. The facing interval of the portion 28 is narrowed. Therefore, the space between the clamping surfaces 3 and 23 at the tip portions of the clip pieces 1 and 21 is expanded. Similarly, when the position of the operation lever 13 is reversed 180 ° from the position shown in FIG.
[0039]
Further, as shown in FIGS. 6 and 7, when the operation lever 13 is tilted rearward (when the operation lever 13 is rotated by approximately 90 ° from the position of the operation lever 13 in FIG. 5), the cam shaft 16 is rotated and the rear extensions 7 and 28 are rotated. The sliding surfaces 12 and 33 on the inner surface of the spring are slid, and the space between the rear extensions 7 and 28 is expanded against the spring force of the spring 18. And the corner | angular part of the cam shaft 16 of a substantially pentagonal cross section engages with the trough-shaped engagement holding part 11 of the back extension part 6, and the trough-shaped engagement holding part 32 of the back extension part 28, and pinching press The surfaces 3 and 23 are joined together, and the sandwiching teeth 5 and 24 are held in the sandwiched state in which the grooves 4 and 25 are fitted.

At this time, as shown in FIG. 6, the front end surface 15 a of the bearing plate 15 is joined to the rear back surface 26 b of the substantially inverted L-shaped portion 26 of the other clip piece 21, so that some external force acts on the operation lever 13. However, the rotation is restricted. Further, in this case, a part 14b of the handle 14 extends in parallel with the cam shaft 16 and is in contact with the back surface of the substantially U-shaped spring 18 while being elastically deformed. It will be a thing.
[0041]
The operation lever 13 is not only in the state of being inverted to the rear extension 7 side of the substantially L-shaped portion 6 shown in FIGS. 4 and 5, but also from the state of being raised to the rear extension portion 28 side of the substantially inverted L-shaped portion 26. The clip C can be held in the above-mentioned sandwiched state by tilting backward. Further, when the clip C is released from being held, the operation lever 13 that has fallen backward can be rotated not only to the rear extension 7 side but also to the rear extension 28 side. Accordingly, since the operation direction of the operation lever 13 is not limited, usability is improved.
[0042]
As described above, the clip C forms an opening 27 in the substantially inverted L-shaped portion 26 of the clip piece 21, and the rear extension portion 7 of the substantially L-shaped portion 6 of the clip piece 1 is inserted into the opening 27 so as to face each other. While the cam shaft 16 of the operation lever 13 is inserted between the rear extensions 7 and 28 and the rotating portion 9 is supported by the support 30, the substantially U-shaped spring 18 is placed behind the rear extensions 7 and 28. Since it is assembled from the end, it can be assembled easily.
[0043]
Each clip piece 1, 21 joins the clamping pressing surfaces 3 and 23 together, and when the clamping teeth 5 and 24 are held in the grooves 4 and 25, The end surface 2a and the front end surface 26a of the substantially inverted L-shaped portion 26 are opposed to each other, and the rear end surface 22a of the sandwiching portion 22 and the front end surface 6a of the substantially L-shaped portion 6 are opposed to each other. Therefore, even if the object to be clamped (not shown) is pulled abruptly and a force for expanding the clamping part 2 or 22 at the tip part of the clip pieces 1 and 21 is applied, the opposed rear end face 2a and front end face are opposed to each other. 26a or the rear end face 22a and the front end face 6a facing each other come into contact with each other to prevent the sandwiching portion 2 or 22 from expanding, thereby preventing the object to be sandwiched from falling off.
