Description

【０００１】
【発明の属する技術分野】
本発明は綴じ具に係り、更に詳しくは、押え部材を綴じ込み位置としたときの操作部材のロック状態を、極めて簡単な操作によって解除することのできる綴じ具に関する。
【０００２】
【従来の技術】
従来の綴じ具としては、表紙体の内面に固定されるベースと、このベースに対して離間接近する方向に移動可能に設けられた押え部材と、当該押え部材にコイルばねを介して連結されるとともに一端を自由端として回転方向に移動可能に設けられ、且つ、常時はコイルばねによって前記自由端側が上方に浮き上がるように力が付与されたアーム状の操作部材とを備えて構成されている。
【０００３】
前記ベースは、表紙体への設置面部と、当該設置面部から起立した起立壁とを備えており、当該起立壁の面内に形成された穴に対し、前記操作部材の自由端側に形成された突片を引っ掛け可能として当該操作部材をロックできる構成となっている。
【０００４】
【発明が解決しようとする課題】
しかしながら、前記綴じ具にあっては、操作部材のロックを解除するときに、当該操作部材の自由端側を下方に押圧すると同時に、起立壁から離れる水平方向にも力を加えなければならず、操作方向が二方向となって操作の簡便性が損なわれるという不都合がある。特に、綴じ込まれた書類の枚数が多いときは、コイルばねの力が強く発揮される状態となっているため、ロック解除の操作力が過大に要求される不都合を招来する。また、前記水平方向への操作は、操作部材にねじれを生じさせるため、当該操作部材の基部側への負荷も大きく、これによる操作部材の変形等に起因して作動不良を惹起するという不都合もある。
【０００５】
【発明の目的】
本発明は、このような不都合に着目して案出されたものであり、その目的は、押し下げ力を操作部材に加えるだけで当該操作部材のロックと、その解除とを可能とした綴じ具を提供することにある。
【０００６】
【課題を解決するための手段】
前記目的を達成するため、本発明は、ベースに一端側が支持されて他端を自由端として移動可能に設けられた操作部材と、当該操作部材の移動によって移動可能に設けられた押え部材と、この押え部材と前記操作部材との間に設けられたばね部材と、前記押え部材が綴じ込み位置に設定されたときに前記操作部材をロックするロック手段とを備えた綴じ具において、
前記ロック手段は、前記操作部材に回転可能に支持された第１の部材と、前記ベースから起立する起立部に設けられるとともに前記第１の部材と相互に作用して前記操作部材をロック及びロック解除する第２の部材とからなり、
前記第１の部材が回転する方向に変位することで前記操作部材の操作力の方向を略一定に保ってロック及びロック解除が可能に設けられ、
前記第１の部材は回転体により構成される一方、前記第２の部材は前記起立部に形成された穴と、前記回転体を変位させるガイド部とにより構成され、
前記回転体は、前記操作部材を操作する毎に所定角度変位して前記ロックとロック解除を繰り返す、という構成を採っている。このような構成では、操作部材に付与する力の方向を変えることなくロック及びロック解除が可能となる。すなわち、従来のように操作部材に対して押圧力の付与と水平方向に移動させる力の付与とを同時に働かせてロックを解除する必要性がなくなるため、操作部材に対する操作力を確実に付与することができる。しかも、操作部材にねじれ等の変形がもたらされることも解消することが可能となる。しかも、回転体の回転を利用するものであるため、滑らかな操作感を得ることができる。
また、本発明は、ベースに一端側が支持されて他端を自由端として移動可能に設けられた操作部材と、当該操作部材の移動によって移動可能に設けられた押え部材と、この押え部材と前記操作部材との間に設けられたばね部材と、前記押え部材が綴じ込み位置に設定されたときに前記操作部材をロックするロック手段とを備えた綴じ具において、
前記ロック手段は、前記操作部材に回転可能に支持された第１の部材と、前記ベースから起立する起立部に設けられるとともに前記第１の部材と相互に作用して前記操作部材をロック及びロック解除する第２の部材とからなり、
前記第１の部材が回転する方向に変位することで前記操作部材の操作力の方向を略一定に保ってロック及びロック解除が可能に設けられ、
前記第１の部材は、前記操作部材の延出方向に沿う方向を回転中心とし、且つ、当該操作部材の幅方向両側に表出する一対の回転体により構成される一方、前記第２の部材は、前記回転体にそれぞれ相対する起立部に形成された一対の穴と、前記回転体を変位させるガイド部とにより構成され、
前記各回転体は、前記操作部材を操作する毎に所定角度変位して前記ロックとロック解除を交互に繰り返す、という構成を採っている。このような構成によれば、操作部材の両側でロック及びロック解除が行なわれるようになり、極めて安定して動作させることができる。
【０００９】
【発明の実施の形態】
本発明において、前記回転体は前記操作部材の幅方向両側に形成された凹部内に略収まる本体部と、この本体部の回転方向に沿う略１８０度間隔位置に設けられて前記穴の形成縁に係り合い可能な一対の溝部とを備え、前記操作部材の自由端側を所定の高さ位置まで押圧操作したときに一方の溝部側が前記ガイド部によって変位して他方の溝部が穴の形成縁に係り合い、再度操作部材を押圧操作したときに前記一方の溝部側がガイド部によって更に変位して他方のガイド部と穴の形成縁との係り合いを解除する、という構成を採っている。このような構成では、溝部が穴の形成縁にしっかりと引っ掛かるようになり、不用意にロックが解除されてしまうおそれを防止することができる。
【００１０】
また、前記起立部の上端側には前記回転体の姿勢調整部が設けられる、という構成を採ることが好ましい。このような構成とすれば、操作部材をロックする際に、回転体が操作部材の凹部から部分的に突出するような傾きを生じていても、これを凹部内に収めて操作部材の移動をスムースに行なうことができ、また、操作時に、回転体とガイド部との相対接触位置を安定して保つことができる。
【００１１】
【実施例】
以下、本発明の実施例を図面を参照しながら説明する。
【００１２】
図１ないし図６には、本実施例に係る綴じ具が示されている。全体構成及びその分解斜視図が示された図１及び図２において、綴じ具１０は、表紙体Ｐの内面側に固定されるベース１１と、このベース１１に支持されたレバー状の操作部材１２と、当該操作部材１２の移動によって前記ベース１１に対して離間接近する方向に移動可能な押え部材１３と、この押え部材１３と操作部材１２との間に設けられたばね部材１４と、前記押え部材１３が図１に示される綴じ込み位置に設定されたときに操作部材１２をロックするロック手段１５と、前記押え部材１３をベース１１上に支持する第１及び第２の連結軸１６、１７とを備えて構成されている。
【００１３】
前記ベース１１は金属材を成形材料として形成されている。このベース１１は、表紙体Ｐの上下方向若しくは左右方向に沿って延びる設置面部２０と、この設置面部２０の短寸幅方向一端に連なって上方に起立する第１の起立部２１と、当該第１の起立部の長手方向一端側（図２中右端側）に相対する第２の起立部２２とにより構成されている。設置面部２０の面内には、その長手方向両側に固定用穴２３，２３が形成され、これらの固定用穴２３を利用してリベット２４（図１参照）を用いて表紙体Ｐにベース１１が固定できるようになっている。また、設置面部２０の短寸幅方向中間部において、長手方向両側には、当該設置面部２０を部分的に切り起こして形成された書類端縁突き当て片２５、２５が設けられているとともに、これら突き当て片２５、２５間には、同様の切り起こしによって形成されたばね軸支持片２６と、これを中間にして一対配置された連結軸支持片２７，２８が形成されている。これらばね軸支持片２６及び連結軸支持片２７，２８の各面内には、軸受穴３０，３１，３２がそれぞれ形成されている。
【００１４】
前記第１の起立部２１は、その面内に前記軸受穴３０，３１，３２に相対する軸受穴３３，３４，３５が形成されているとともに、前記第２の起立部２２に相対する領域、すなわち、図２中右端側領域には、ロック手段１５の第２の部材を構成する四角形状の穴３６が設けられている。この一方、第２の起立部２２にも、穴３６と略同一形状に打ち抜いて形成されたロック手段１５の第２の部材を構成する穴３７が設けられている。また、第１及び第２の起立部２１，２２において、前記穴３６，３７近傍の上縁には、上方に向かうに従って外側に傾斜して操作部材１２の自由端側を受け入れ易くし、且つ、後述する回転体の姿勢を一定に保つ姿勢調整部としての案内片３８，３９が設けられている。なお、図３に示されるように、ベース１１の設置面部２０において、前記穴３６，３７間には、これらの穴３６，３７と共に第２の部材を構成するガイド部４０が固定されている。
【００１５】
前記操作部材１２は合成樹脂材料によって形成されている。この操作部材１２は、図８に示されるように、その長手方向（左右方向）一端側において短寸幅方向（紙面直交方向）に貫通する軸受穴４１を備えている一方、他端側の短寸幅方向両側に、ロック手段１５を構成する第１の部材としての回転体４２，４２（図２参照）をそれぞれ回転可能に受け入れ可能な凹部４３，４３を備えて構成されている。また、操作部材１２は、長手方向中央部領域に垂下片４４を備え、当該垂下片４４には、前記ばね部材１４の屈曲端部１４Ｂを受容する溝４５が形成されている。この溝４５は、図８（Ａ）に示されるように、中間部が左右両側よりも高くなるように設けられており、操作部材１２を倒伏、起立させたときに、ばね部材１４の屈曲端部１４Ｂが溝４５に沿って移動できるようになっている。また、前記凹部４３，４３は、図８（Ｃ）に示されるように、幅方向中間に垂下する仕切壁４６によって区分され、操作部材１２の短寸幅方向両側には、回転体４２の回転中心軸を操作部材１２の長手方向（延出方向）とするピン４７（図２参照）の挿入穴４９，４９が形成されている。なお、前記垂下片４４において、長手方向に沿う二箇所には、切欠部５０，５１が形成され、切欠部５０によってばね部材１４のコイル部１４Ａ（図２参照）との干渉が回避され、切欠部５１によって第２の連結軸１７との干渉が回避されるようになっている。
【００１６】
前記操作部材１２は、図２に示されるように、軸受穴４１と、前述した連結軸支持片２７及び第１の起立部２１の軸受穴３４とを一致させて第１の連結軸１６を挿入することにより、一端側がベース１１に支持されて他端側を自由端とした回転移動が可能となる。
【００１７】
前記回転体４２は、図２、図９ないし図１２に示されるように、操作部材１２の凹部４３，４３内に位置したときに操作部材１２の側面１２Ａ内、すなわち凹部４３内に略収まる本体５３と、この本体５３の図１１中上下両側、すなわち、後述する回転方向に沿う略１８０度間隔位置に設けられて前記穴３６，３７の上端形成縁に係り合い可能な一対の溝部５４，５４とを備えて構成されている。本体５３は、中央部５３Ａと、この中央部５３Ａに連なって前記溝部５４を形成する上下各一対の爪部５３Ｂとにより構成され、中央部５３Ａには、前述したピン４７の貫通穴５６が形成されている。各爪部５３Ｂは、図９，図１０に示されるように、操作部材１２の長手方向に沿う本体部５３Ａの長さよりも短くするための切欠部５３Ｃを長さ方向に沿って対称となる位置に備えて構成されている。また、溝部５４は、断面視で中央部が最も低位置となるくの字状の溝形状となっている。なお、他方の回転体４２は、図１０の中心線Ｃに対して左右対称形状をなすものにより構成されている。
【００１８】
前記押え部材１３は、図２に示されるように、平面視略長方形状に設けられるとともに上面に二つのスリット穴６０Ａ，６０Ａを備えた樹脂製のカバー６０と、このカバー６０の下面側に装着されるとともに、二枚の押え片６１，６１を一体化してなる押圧体６２とにより構成されている。カバー６０は、ここでは詳細構造を図示省略しているが、その下面側が押圧体６２を嵌め込み可能な形状に設けられている。
【００１９】
前記押圧体６２はステンレス等の金属によって形成されている。また、押え片６１は、押圧体６２がカバー６０の下面側に嵌め込まれたときに、その下端がカバー６０の下端より若干突出する程度の上下方向幅に設けられている。押え片６１の面内には、第１及び第２の連結軸１６，１７と、ばね部材１４の各軸部分が挿入される軸受穴６４，６５，６６が形成されている。
【００２０】
前記第２の部材を構成するガイド部４０は、図３及び図１３に示されるように、ベース１１の設置面部２０上に位置する平坦面部７０と、この平坦面部７０の上面側に形成された一対の隆起部７１と、平坦面部７０の下面側に設けられて設置面部２０に形成された角穴７４（図２参照）に嵌合する脚部７５とにより構成されている。隆起部７１，７１は、それぞれ平面視略Ｌ字状をなして対称配置とされており、それらの内方端（平坦面部７０の中央側）が低く、外方端が高くなる傾斜面に形成されている。また、隆起部７１は、そのＬ字の縦辺７１Ａ側が操作部材１２の長手方向に沿う一方、Ｌ字の横辺７１Ｂ側が操作部材１２の短寸幅方向に沿い、且つ、前記回転体４２の下方に位置するようになっている。ここで、隆起部７１における縦辺７１Ａの長さＬは、前述した回転体４２の長さよりも若干短く設定されているとともに、前記横辺７１Ｂの長さＬ１は、回転体４２の爪部５３Ｂに設けられた切欠部５３Ｃの切欠長さに略等しいか僅かに小さくなるように設定されている。
【００２１】
なお、図２中、符号８０は、ばね部材１４のコイル部１４Ａ内にスペーサ筒８１を介して貫通する軸を示し、符号８２は、押え部材１３のカバー６０側に設けられた図示しない爪片が嵌合して押圧体６２の脱落を防止するための切欠穴を示す。
【００２２】
次に、前記実施例に係る綴じ具１０の組み立て要領について説明する。
【００２３】
押え部材１３の組み立てに際しては、当該押え部材１３のカバー６０の下面側に押圧体６２を強制的に嵌合させる。そして、この押え部材１３の一方の側端から第１及び第２の連結軸１６，１７の各一端側を押え片６１，６１の軸受穴６４，６５に挿入して貫通させ、その先端をかしめて抜け止め防止処理を行なう。同時に、ばね部材１４の一端側を押え片６１，６１の軸受穴６６に挿入して貫通させ、同様に先端をかしめて抜け止め処理を行なう。
【００２４】
この一方、ベース１１にはガイド部４０が装着される。この装着は、ガイド部４０の脚部７５をベース１１の設置面部２０に設けられた角穴７４に強制的に嵌め込むことによって行なうことができる。
【００２５】
また、前記回転体４２，４２は、操作部材１２の凹部４３，４３内にそれぞれ配置され、操作部材１２の自由端側から差し込まれるピン４７を貫通穴５６に貫通させることによって操作部材１２に回転可能に保持される。
【００２６】
次いで、操作部材１２の基端側をベース１１の連結軸支持片２７と第１の起立部２１との間に配置し、前記第１の連結軸１６の他端側を挿入してその先端をかしめて抜け止め処理を行なう。これにより、操作部材１２は、前述した回転体４２が設けられている側を自由端として回転可能に保持されることとなる。
【００２７】
この際、ばね部材１４のコイル部１４Ａ内にスペーサ筒８１を挿入した状態でコイル部１４Ａを操作部材１２の切欠部５０内に配置するとともに、ばね軸支持片２６と第１の起立部２１間にコイル部１４Ａを位置させる。そして、軸８０をばね軸支持片２６側から挿入して第１の起立部２１の軸受穴３３から突出させ、先端をかしめて抜け止め処理を行なう。また、ばね部材１４の屈曲端部１４Ｂは、操作部材１２の垂下片４４に設けられた溝４５内に差し込まれる。
【００２８】
第２の連結軸１７の他端側は、連結軸支持片２８の軸受穴３２側から挿入されて第１の起立部２１の軸受穴３５より突出させて先端のかしめ処理が行なわれ、これによって、綴じ具１０の組み立てを完了することができる。
【００２９】
次に、前記綴じ具１０における操作部材１２のロック及びロック解除動作について、図１４ないし図１８を参照しながら説明する。
【００３０】
操作部材１２がロック解除された状態では、当該操作部材１２は、ばね部材１４のばね力によって自由端側が上方位置となる傾斜姿勢となる（図６参照）。そして、操作部材１２の自由端側を押し下げ方向に操作すると、当該自由端側が第１の起立部２１と第２の起立部２２間に受容されることとなる。このとき、操作部材１２は、前述した案内片３８，３９によって正確に案内され、且つ、回転体４２，４２が図１４（Ａ）に示される位置に対して傾いている場合があっても、当該傾きは案内片３８，３９及びこれに連なる起立部２１，２２の内面によって補正され、同図に示す位置、すなわち、操作部材１２の凹部４３，４３内にそれぞれ略収まる姿勢となる。
【００３１】
図１４（Ａ）に示される位置よりも更に操作部材１２を押し下げると、下方内側に位置する爪部５３Ｂが隆起部７１の横片７１Ｂに接し、その傾斜に従って回転体４２の上部が外側位置となるように回転して傾斜姿勢に変位することとなる（図１４（Ｂ）〜（Ｄ）参照）。この際、下方外側の爪部５３Ｂは、前述した切欠部５３Ｃ（図１０参照）が設けられているため、横片７１Ｂに干渉することはない。
【００３２】
操作部材１２の押し下げが限界位置まで行なわれた後に、当該操作部材１２への操作力すなわち押し下げ力を解除すると、ばね部材１４のばね力によって操作部材１２の自由端側が上方に移動することとなる（図１５（Ａ）参照）。このとき、回転体１２は、傾いた姿勢にあるため、上方の溝部５４が穴３６，３７の上部形成縁に引っ掛かることとなり、これによって操作部材１２のロック状態が確保される。この際、図１に示されるように、押圧部材１３は、ベース１１の設置面部２０に接して、所定の綴じ込み力を発揮した状態となる。
【００３３】
操作部材１２のロックを解除する場合には、当該操作部材１２の自由端側を再び押し下げればよい。すなわち、図１５（Ｂ）及び（Ｃ）に示されるように、押し下げにより、下方外側に位置する爪部５３Ｂが隆起部７１の縦片７１Ａに接し、その傾斜に応じて回転体４２が更に回転して上方内側に位置する爪部５３Ｂが穴３６，３７内に位置することとなる。
【００３４】
操作部材１２の押し下げが限界となったときに、その押し下げ力を解除すると、操作部材１２の自由端側がばね部材１４によって上昇し、このとき、上部内側の爪部５３Ｂが穴３６，３７の上部形成縁に接することとなり（図１５（Ｄ）参照）、この後、回転体４２は更に回転することとなる（図１６（Ａ）〜（Ｄ）参照）。そして、図１６（Ｄ）の状態では、回転体４２，４２が傾いた姿勢となるが、操作部材１２が第１及び第２の起立部２１，２２から脱出するときに、これら起立部２１，２２の内面によって回転体４２，４２は、一対の溝部５４，５４が略鉛直方向に沿う上下に位置する姿勢に調整された状態で各起立部２１，２２から上方に脱出することとなる（図１７（Ａ）〜（Ｃ）参照）。従って、次に操作部材１２をロックさせる際の動作を確実に行なわせることができる。
【００３５】
このように、操作部材１２の押し下げを行なう毎に、ロック及びその解除を交互に繰り返すこととなる。
【００３６】
従って、このような実施例によれば、単に操作部材１２の自由端側をガイド部４０に向かって押圧するだけでよいため、操作が非常に簡単になるという効果を得る。
【００３７】
なお、前記実施例では、回転体４２を二つ設けて操作部材１２の幅方向両側でロック及びロック解除を行なう構成を図示、説明したが、本発明はこれに限定されるものではなく、操作部材１２の片側のみに回転体４２を設けてロック手段１５を構成することもできる。但し、前記実施例の構成によれば、ロック状態の安定度が高められるという利点がある。
【００３８】
また、前記実施例では、回転体４２が操作部材１２の短寸幅方向両側に設けられた構成としたが、例えば、操作部材１２の自由端面側に一個の回転体４２を受容する一方、これに対応する穴を備えた起立部をベース１１に設け、当該ベース１１にガイド部４０を図示の状態に対して平面内で略９０度向きを変更し配置する構成等も採用することができる。
【００３９】
【発明の効果】
以上説明したように、請求項１記載の発明によれば、操作部材に付与する力の方向を変えることなくロック及びロック解除が可能となる。すなわち、操作部材に対して、押圧力の付与と水平方向に移動させる力の付与とを同時に働かせてロックを解除する必要性がなくなるため、操作部材に対する操作力を確実に付与することができる。しかも、操作部材に付与する力の方向が一定であるため、操作部材にねじれ等の変形がもたらされることも解消することが可能となる。また、操作部材の操作に際して滑らかな操作感を得ることができる。
【００４１】
更に、請求項２記載の発明によれば、ロックとロック解除動作が操作部材の両側で行なわれるようになり、更に安定した動作を行なわせることができる。
【００４２】
また、請求項３記載の発明によれば、溝部が穴の形成縁にしっかりと引っ掛かるようになり、不用意にロックが解除されてしまうおそれを防止することができる。
【００４３】
更に、請求項４記載の発明によれば、操作部材の移動をスムースに行なうことができ、また、操作時に、回転体とガイド部との相対接触位置を安定して保つことができる。

BACKGROUND OF THE INVENTION
The present invention relates to a binding tool, and more particularly, to a binding tool that can release a locked state of an operation member when a pressing member is set to a binding position by an extremely simple operation.
[0002]
[Prior art]
As a conventional binding tool, a base fixed to the inner surface of a cover body, a pressing member provided so as to be movable toward and away from the base, and the pressing member are connected via a coil spring. In addition, an arm-shaped operation member is provided which is provided so as to be movable in the rotation direction with one end as a free end, and is normally provided with a force so that the free end side is lifted upward by a coil spring.
[0003]
The base includes an installation surface portion on the cover body and an upright wall standing upright from the installation surface portion, and is formed on a free end side of the operation member with respect to a hole formed in the surface of the upright wall. The operation member can be locked so that the protruding piece can be hooked.
[0004]
[Problems to be solved by the invention]
However, in the binding tool, when unlocking the operating member, the free end side of the operating member must be pressed downward, and at the same time, a force must be applied in the horizontal direction away from the standing wall, There is an inconvenience that the operation direction becomes two directions and the simplicity of operation is impaired. In particular, when the number of bound documents is large, the force of the coil spring is exerted strongly, which causes inconvenience that the operation force for unlocking is excessively required. In addition, since the operation in the horizontal direction causes the operation member to be twisted, a load on the base side of the operation member is large, which causes a disadvantage of causing malfunction due to deformation of the operation member. is there.
[0005]
OBJECT OF THE INVENTION
The present invention has been devised by paying attention to such inconveniences, and an object of the present invention is to provide a binding tool that can lock and release the operation member only by applying a pressing force to the operation member. It is to provide.
[0006]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the present invention provides an operation member that is supported at one end side by the base and is movable with the other end as a free end, and a presser member that is movable by movement of the operation member, In a binding tool including a spring member provided between the pressing member and the operation member, and a lock unit that locks the operation member when the pressing member is set at a binding position.
The lock means is provided on a first member rotatably supported by the operation member, and an upright portion that stands up from the base and interacts with the first member to lock and lock the operation member. A second member to be released,
The first member is displaced in the rotating direction so that the direction of the operating force of the operating member is kept substantially constant and can be locked and unlocked .
The first member is constituted by a rotating body, while the second member is constituted by a hole formed in the upright part and a guide part for displacing the rotating body,
The rotating body is configured to be displaced by a predetermined angle each time the operating member is operated and to repeat the locking and unlocking . In such a configuration, locking and unlocking can be performed without changing the direction of the force applied to the operation member. That is, since it is not necessary to release the lock by simultaneously applying the pressing force and the horizontal movement force to the operation member as in the conventional case, the operation force to the operation member should be reliably applied.

[0029]
Next, the locking and unlocking operation of the operation member 12 in the binding tool 10 will be described with reference to FIGS.
[0030]
In a state where the operation member 12 is unlocked, the operation member 12 is in an inclined posture in which the free end side is in the upper position by the spring force of the spring member 14 (see FIG. 6). When the free end side of the operation member 12 is operated in the push-down direction, the free end side is received between the first upright portion 21 and the second upright portion 22. At this time, the operation member 12 is accurately guided by the guide pieces 38 and 39 described above, and the rotating bodies 42 and 42 may be inclined with respect to the position shown in FIG. The inclination is corrected by the guide pieces 38 and 39 and the inner surfaces of the upright portions 21 and 22 connected to the guide pieces 38 and 39, and the postures are substantially contained in the positions shown in the figure, that is, the recesses 43 and 43 of the operation member 12, respectively.
[0031]
When the operation member 12 is further pushed down from the position shown in FIG. 14A, the claw portion 53B located on the lower inner side comes into contact with the horizontal piece 71B of the raised portion 71, and the upper portion of the rotating body 42 is moved to the outer position according to the inclination. It will rotate so that it may become, and it will be displaced to an inclination posture (refer to Drawing 14 (B)-(D)). At this time, the lower outer claw portion 53B does not interfere with the horizontal piece 71B because the notch portion 53C (see FIG. 10) described above is provided.
[0032]
After the operation member 12 is pushed down to the limit position, when the operation force on the operation member 12, that is, the push-down force is released, the free end side of the operation member 12 is moved upward by the spring force of the spring member 14. (See FIG. 15A). At this time, since the rotating body 12 is in an inclined posture, the upper groove portion 54 is hooked on the upper formation edge of the holes 36 and 37, thereby ensuring the locked state of the operating member 12. At this time, as shown in FIG. 1, the pressing member 13 comes into contact with the installation surface portion 20 of the base 11 and exhibits a predetermined binding force.
[0033]
In order to release the lock of the operation member 12, the free end side of the operation member 12 may be pushed down again. That is, as shown in FIGS. 15B and 15C, by pressing down, the claw portion 53B located on the lower outer side contacts the vertical piece 71A of the raised portion 71, and the rotating body 42 further rotates according to the inclination thereof. Thus, the claw portion 53 B located on the upper inner side is located in the holes 36 and 37.
[0034]
When the push-down force is released when the push-down of the operation member 12 becomes the limit, the free end side of the operation member 12 is lifted by the spring member 14, and at this time, the upper inner claw portion 53 B is located above the holes 36 and 37. It will be in contact with the forming edge (see FIG. 15D), and then the rotating body 42 will further rotate (see FIGS. 16A to 16D). In the state of FIG. 16D, the rotating bodies 42 and 42 are inclined, but when the operating member 12 escapes from the first and second upright portions 21 and 22, the upright portions 21 and 22, the rotating bodies 42 and 42 escape upward from the upright portions 21 and 22 in a state in which the pair of groove portions 54 and 54 are adjusted to a posture in which the pair of groove portions 54 and 54 are positioned vertically along the substantially vertical direction (see FIG. 17 (A) to (C)). Therefore, the operation for locking the operation member 12 next can be performed reliably.
[0035]
Thus, every time the operating member 12 is pushed down, the lock and the release thereof are repeated alternately.
[0036]
Therefore, according to such an embodiment, since it is only necessary to press the free end side of the operation member 12 toward the guide portion 40, there is an effect that the operation becomes very simple.
[0037]
In the above-described embodiment, the configuration in which the two rotating bodies 42 are provided and the operation member 12 is locked and unlocked on both sides in the width direction is illustrated and described. However, the present invention is not limited to this, and the operation is not limited thereto. It is also possible to form the lock means 15 by providing the rotating body 42 only on one side of the member 12. However, according to the configuration of the embodiment, there is an advantage that the stability of the locked state is increased.
[0038]
In the above-described embodiment, the rotating body 42 is provided on both sides of the operation member 12 in the short width direction. However, for example, one rotating body 42 is received on the free end face side of the operating member 12. It is also possible to employ a configuration in which an upright portion having a hole corresponding to is provided in the base 11 and the guide portion 40 is disposed on the base 11 with its orientation changed approximately 90 degrees in the plane with respect to the illustrated state.
[0039]
【The invention's effect】
As described above, according to the first aspect of the present invention, locking and unlocking can be performed without changing the direction of the force applied to the operation member. That is, since it is not necessary to release the lock by simultaneously applying the pressing force and the force for moving in the horizontal direction to the operating member, it is possible to reliably apply the operating force to the operating member. In addition, since the direction of the force applied to the operation member is constant, it is possible to eliminate the deformation such as torsion of the operation member. In addition, a smooth operation feeling can be obtained when operating the operation member.
[0041]
According to the second aspect of the present invention, the locking and unlocking operations are performed on both sides of the operation member, and a more stable operation can be performed.
[0042]
Further, according to the invention described in claim 3, it is possible to prevent the groove from being inadvertently unlocked because the groove is firmly caught on the hole forming edge.
[0043]
Furthermore, according to the fourth aspect of the present invention, the operation member can be moved smoothly, and the relative contact position between the rotating body and the guide portion can be stably maintained during operation.
