Description

【0001】
【発明の属する技術分野】
本発明は、2つの部材を結合させる際に好適に用いられる部材結合装置に関するものである。
【0002】
【従来の技術】
例えば、複数のパネルを連結して構築される可動間仕切壁の一つのタイプとして、各パネルの構造枠を構成している縦枠材同士を直接ボルトを用いて結合するようにしたものがある。
【0003】
このような形式のものにおいては、例えば、一方のパネルの縦枠材にナット要素を設けておき、他方のパネルの縦枠材側から接合面に直交させて挿入したボルトを前記ナット要素に締着することによって、前記縦枠材同士を結合するようにしている。
【0004】
【発明が解決しようとする課題】
ところが、上述のように接合面に対して直交する向きにボルトを締結するようにすると、例えば、高さ違いのパネルの縦枠材同士を結合する場合における横枠材などのように、前記ボルトを接合面に直交する向きに挿入するのを妨げる部材が存在する場合には、その位置を避けてボルトを挿入しなければならず、結合位置が限定されてしまう。
【0005】
そこで、接合面に対して傾斜した方向に配される傾斜ボルトを用いて結合することが考えられるが、このようになものであれば、今度は前記縦枠材同士が相対的に上下方向にずれてしまうという可能性を生じる。
【0006】
このような不具合を解消するための万策としては、例えば、一方の縦枠材の接合面に位置決め用の突起や爪部を設けるとともに、他方の縦枠材の接合面に前記突起や爪部が嵌まり込む位置決め孔を設けておき、斜めにボルトを締結しても縦枠材同士が接合面に沿ってずれを起こすというような事態が生じないようにすることが考えられる。
【0007】
しかしながら、このような突起や爪部を縦枠材に設けておくと、使用しない場合にその突起や爪部が邪魔になるという問題が生じる。例えば、構築された可動間仕切壁の形態を変更するために、全体を分解することなしに中間のパネルのみを抜き取ったり交換したいという要望がある。しかしながら、かかる突起や爪部が固定的に存在していると、ボルトを外してもその突起や爪部が邪魔をして中間のパネルのみを抜き取れないという不具合が発生する。
【0008】
そして、このような不具合は、パネルの縦枠材に限らず様々な部材の結合に際して生じ得るものである。
【0009】
【課題を解決するための手段】
すなわち、本発明は、上記の不具合を解決すべくなされたものであり、2つの部材を、その接合面に対して傾斜した方向に配される傾斜ボルトを用いて結合するようにした部材結合装置であって、一方の部材の内部に挿入される裏当メンバと、この裏当メンバに設けられ他方の部材側から挿入された傾斜ボルトと係わり合うナット要素と、前記裏当メンバに設けられ不要時に邪魔にならない位置に退避可能なずれ止め要素と、このずれ止め要素を挿入後の裏当メンバから突出させて他方の部材を位置決めし、ずれを防止するずれ防止手段を設けたものである。なお、傾斜ボルトは、上方から斜めに挿入するものも、下方から斜めに挿入するものも含んでいる。
【0010】
このようなものであれば、必要時にのみ突出するずれ止め要素によって、傾斜ボルトによる結合で生じる上下方向のずれを防止させることができるようになる。さらに、ずれ止め要素を退避させることによって、裏当メンバの挿入動作をスムーズに行うことができる。
【0011】
さらに、ずれ止め要素を突出させるための別の機構を設けないで簡単な構成にするためには、ずれ止め手段を、傾斜ボルトの締め付け力を利用してずれ止め要素を突出させるように構成することが望ましい。
【0012】
このようなずれ止め手段として具体的な態様としては、ずれ止め手段を、ナット要素を具備するスライダと、このスライダを所要の範囲内において進退動作可能に案内する要素を設けて、傾斜ボルトの締め付けによるスライダの移動に基づいて、ずれ止め要素を突出させるように構成することが挙げられる。
【0013】
また、部品点数を少なくして構成を簡素にするためには、ずれ止め要素として、スライダに位置決めのための当て面を備えた爪部を一体に設けるとともに他方の部材には位置決め部を設けて、スライダの移動に伴って爪部を突出させ、この爪部の当て面を位置決め部に当てて他方の部材を位置決めするよう構成することが望ましい。
【0014】
このような爪部による位置決めをより精度の高いものとするためには、爪部の当て面を、両部材の位置決め部に同時に当て得るように構成し、接合させる2つの部材同士の位置決めを爪部を介して直接行うようにすることが望ましい。
【0015】
また、裏当メンバが、該裏当メンバの使用位置での移動を禁止する移動禁止用段部を具備し、この移動禁止用段部を位置決め部に当てるように構成したものである場合に、部材同士を結合させた際にこの移動禁止用段部と前記位置決め部の接触面において部材から裏当メンバに対して強い力が作用しないようにするためには、爪部の当て面を、該爪部を最も突出させた場合に移動禁止用段部に優先して位置決め部に当て得るように位置づけることが望ましい。このようなものでれば、裏当メンバのケーシングを例えば合成樹脂など剛性の弱いもので成形してもよく、ケーシングの材質選択の自由度が増し、コストの低減も図ることができるようになる。
【0016】
また、このように爪部に部材の力を作用させる場合は、爪部を、鉄など剛性を有する金属で成形することが望ましい。このようなものであれば、該爪部を繰り返し使用することができるようになる。
【0017】
部品を共通化させて製造の利便性を向上するようにするためには、裏当メンバの、さらに他方の部材に挿入するための傾斜ボルトの頭部を受ける座受要素を備えることが望ましい。すなわち、同じ裏当メンバをそれぞれの部材に挿入することで、部材同士を結合することができるようになる。
【0018】
また、本発明の別の態様としては、一方の部材の内部に挿入される裏当メンバと、裏当メンバに設けられ傾斜ボルトの頭部を受ける座受要素と、他方の部材側に設けられた前記傾斜ボルトと係わり合うナット要素と、前記裏当メンバに設けられ不要時には邪魔にならない位置に退避可能なずれ止め要素と、このずれ止め要素を挿入後の裏当メンバから突出させて他方の部材を位置決めしてずれを防止するずれ防止手段を設けたものが挙げられる。なお、このような態様における、ずれ防止手段は、例えば、ボルトの座受要素にかかる押圧力に基づいて爪部を突出させるようなものが挙げられる。
【0019】
また、本発明の部材結合装置をより有効に活用するためには、裏当メンバを種々の場所に付け替えられるように着脱可能に構成することが望ましい。
【0020】
また、本発明の部材結合装置をその効果を有効に発揮する対象部材としては、パネル要素が装着されるパネルの構造材を構成する縦枠材が望ましい。
【0021】
さらに、異なる高さを有する縦枠材同士を結合する場合に適用すれば、その効果をより有効に発揮する。
【0022】
【発明の実施の形態】
以下、本発明の実施形態を図面を参照して説明する。
【0023】
図1は、オフィス等において使用される可動間仕切壁Wの一部を示している。この可動間仕切壁Wは、第1のパネル1Aと、この第1のパネル1Aよりも背の低い第2のパネル1Bとを備えたもので、これら両パネル1A、1B同士を部材結合装置Cを用いて結合させている。
【0024】
第1のパネル1Aは、構造枠2の前後両面にパネル要素Pを装着してなるもので、この構造枠2は、左右対をなす構造材たる縦枠材3Aを複数本の横枠材4により結合してなる。第2のパネル1Bは、前記構造枠2よりも背の低い構造枠2の前後両面にパネル要素2を装着してなるもので、左右対をなす縦枠材3Bを複数本の横枠材4により結合してなる。
【0025】
各構造枠2の縦枠材3A、3Bは、図2から図4に示すように、それぞれ剛性を有する板金素材に曲げ加工を施すことにより作られたもので、対をなす前後の面板30、31と、これら両面板30、31の外方側縁間に位置する外側端板32と、前記両面板の内側縁間に位置する内側端板33とを一体的に備えた略角パイプ状をなしている。この縦枠材3A、3Bを構成する板金素材の切断端縁は、前記内側端板33の中央部において溶接等により接合されている。
【0026】
さらに、本実施の形態では、両面板30、31の対向する位置にフック孔5をそれぞれ設けるとともに、外側端板32における一方の面板30または31(図4では面板31)寄りに偏移した部位に、両面板30、31のフック孔5同士の対面を遮断する突条6を板金素材の曲げ加工により一体に形成している。さらに、外側端板32の中央領域にパネル1A、1B同士を連結するための開口要素7を設けている。この開口要素7は、縦枠材3Aおよび3Bの空間S内上端部分に装着する第2の結合具Vに関わる開口要素7aと、空間S内中途位置に挿入する裏当構造体たる第1の結合具Nに関わる開口要素7bとを具備してなる。開口要素7aは、第2の結合具位置決め孔70、ボルト連通孔71、位置決め孔72とからなる。また、開口要素7bは、ボルト連通孔73と、開口部74とからなる。この開口要素7bは、縦枠材3A、3Bの長さに対応させて設たもので、図2および図3においては縦枠材3A、3Bとに共通する部分を図示しているため開口要素7bを一カ所の図示しているが、縦枠材3Aには、図1および図13に示すようにを、上下2カ所設けられている。
【0027】
フック孔5は、棚などのオプション部材を掛かり止めるために、縦枠材3A、3Bの前後の面板30、31の側縁近傍に所定のピッチで上下方向に設けたのものである。
【0028】
突条6は、図4に示すように基端を縦枠材3A、3Bの外側端板32に連続させて相互に密着する2枚の突出片部60と、これら突出片部60の先端間を一体に連続させる屈曲部61とからなる構成した平面視略U字状で縦枠材3A、3Bの上下端に渡って設けたものである。そして、図4に示すように基端から屈曲部61の先端部分までの幅Dをフック孔5のパネル要素2の面方向の幅dより長く設定して、フック孔5間を直接に通過する光を遮断可能にしている。
【0029】
パネル要素Pは、板金製の板状部材の内面に芯材を充填してなる長方形状のもので、裏面側に図示しない爪部を備えており、その爪部を利用して前記縦枠材3A、3Bや、横枠材4に着脱可能に装着されている。なおパネル要素2の左右方向寸法は、構造枠2の左右幅寸法よりも小さく設定してある。そのため、各パネル要素2は、各構造枠2に設けたフック孔5を避けるように装着される。この図示例では、装着状態においてパネル要素2の裏面が縦枠材3A、3Bの面板30、31に密接するようにしているが、例えば、パネル要素2の爪部に図示しない適宜なかさ上げ用のスペーサ要素を設けて、装着されたパネル要素Pの裏面と縦枠材3A、3Bとの間に隙間が形成されるようにしてもよい。
【0030】
部材結合装置Cは、図1および図11に示すように第1のパネル1Aの縦枠材3Aにおける中途位置に装着した裏当構造体たる第1の結合具Nと、第2のパネル1Bの縦枠材3Bの上端部に装着した第2の結合具Vと、この第2の結合具V側から挿入され前記両縦枠材3A、3Bの接合面320に対して略45度傾斜した方向に配される傾斜ボルト10とを備えてなる。
【0031】
第1の結合具Nは、図5および図11に示すように内部に空間Sを有しその空間Sを外部に連通させる開口部74を備えた部材、すなわち、前記縦枠材3Aに装着されるものである。具体的には、第1の結合具Nは、前記開口部74を通過させ前記空間S内に挿入されるナット機能付き裏当メンバ8と、このナット機能付き裏当メンバ8を前記空間S内の内面に沿って、図6および図11に示す使用位置まで移動させた段階で前記開口部74の上端部74aに当ててこのナット機能付き裏当メンバ8のそれ以上の移動を禁止する移動禁止用段部8aと、使用位置にあるナット機能付き裏当メンバ8と前記開口部74の下端部74bとの間に割り込んでこのナット機能付き裏当メンバ8を固定する突っ張りメンバ9とを具備してなる。
【0032】
ナット機能付き裏当メンバ8は、図5〜図7および図11、図12に示すように前記縦枠材3Aの開口部74を通してその縦枠材3Aの空間S内に挿入可能なケーシング80を主体に構成されており、不要時にはケーシング80の内部に退避可能なずれ止め要素Yと、このずれ止め要素Yを挿入後のケーシング80の外へ突出させて他方の縦枠材3Bを位置決めし両縦枠材3A、3Bの相対的なずれを防止するずれ防止手段Zとを具備してなる。
【0033】
具体的に説明すれば、ケーシング80は、アルミダイキャスト製のもので、図5および図7に示すように前記開口部74の内方寸法よりも若干小さな外形寸法を有したブロック状をなしており、前記接合面320と直交する方向から前記空間S内に挿入し得るようになっている。ケーシング80の上半部における挿入方向寸法Eは、ケーシング80の下半部の挿入方向寸法eよりも小さく設定してあり、この上半部と下半部との境界に前記移動禁止用段部8aが形成されている。すなわち、このケーシング80は、前記開口部74に挿入した後、前記移動禁止用段部8aが、該開口部74の上端部74aに当たる位置まで、縦枠材3Aの内面に沿ってスライド移動させることができるようになっている。そして、このケーシング80内にスライダ81を傾斜ボルト10の軸心方向に進退し得るように収容し、このスライダ81を所要の範囲内において進退動作可能に案内するための案内穴82を形成するとともに、ケーシング80の裏当面に前記案内穴82を外方へ開放するボルト挿通孔83と、爪部突出口84とを開口させており、前記ボルト挿通孔83を通してケーシング80内に挿入した傾斜ボルト10を前記スライダ81のねじ孔81aにねじ込むことができるようにしてある。また、前記スライダ81の先端部には、前記ずれ止め要素Yを構成する爪部81bが一体に設けてある。この爪部81bは、前記移動禁止用段部8aと平行な当て面81b1を有しており、剛性を有する金属により作られている。そして、この爪部81bは、前記スライダ81が傾斜ボルト10のねじ作用によりケーシング80の裏当面側に移動した際に、前記爪部突出口84を通して外方へ突出するようになっており、限界まで移動した位置で前記当て面81b1が第2のパネル1Bの縦枠材3Bに設けた位置決め孔72の上端部72aに当たるようになっている。
【0034】
従ってこの図示例においては、ずれ防止手段Zは、爪部81bを備えたスライダ81と、案内穴82とを具備し、傾斜ボルトの締め付けによるスライダの移動に基づいてずれ止め要素Yを構成する前記爪部81bを突出させ、この爪部81bの当て面81b1を縦枠材3Bに設けた位置決め孔72の上端部72aに当てて縦枠材3A、3Bの相対的なずれを防止するように構成されている。
【0035】
具体的には、スライダ81を直方体の一部を切り欠いた角部を有する形状に形成するとともに案内穴82の断面をこのスライダ81の形状に対応させて、傾斜ボルト10のねじ孔81aに対する締め付けに伴う回転を禁止するともに、スライダ81の案内穴82に接触する部分を磨くなどして摩擦力を低減させ、案内穴82内に接合面320側へ移動するように形成している。
【0036】
また、この案内穴82は、孔部820と、別体のストッパ85と、スライダ81の接合面320側への移動を規制する規制壁821とを具備し、爪部81bを最も突出させる突出位置Lと、爪部81bをケーシング80内へ退避させる退避位置Mとの間でスライダ81を進退可能に案内させるように構成したものである。孔部820は傾斜ボルト10の軸方向に略一致した角度に傾斜させたものである。ストッパ85は、その先端部850をケーシング80の接合面320側に設けた第1のストッパ取付部86aに係り合わせるとともに、内側端板33側に位置する係り合わせ突部851をケーシング80を開口させて設けた第2のストッパ取付部86bに係り合わせて取り付けて、孔部820の下端部を開口させたスライダ81の挿入口822(図11参照)において該スライダ81の落下を防止するものである。規制壁821は、ボルト挿通孔83との間に爪部81bを最も突出させた位置でスライダ81の接合面320側への移動を禁止するように設けたものである(図8参照)。
【0037】
さらに、本実施の形態では、前記爪部81bの当て面81b1を縦枠材3Bの位置決め孔72の上端部72aと、縦枠材3Aに設けた開口部74の上端部74aとに同時に当てる当て機構Tを設けている。この当て機構Tは、前記移動禁止用段部8aを爪部突出口84の上端84aよりも低く設けるとともに、前記規制壁821を当て面81b1が爪部突出口84の上端部分にほぼ当たるような位置に設けて、突出位置Lにおいて当て面81b1を移動禁止用段部8aより若干高くなるようにして、縦枠材3Aに設けた開口部74の上端部74aに対して移動禁止用段部8aに優先して当たるようにしたものである。
【0038】
突っ張り部材9は、回動軸90を備え、この回動軸90をケーシング80の裏当面側下端部に設けた軸受部8bに回動可能に支持させた合成樹脂製のものである。さらにストッパ85の先端に設けた落下防止部85aによって下方に落下しないようにしている。そして、前記回動軸90によって、図7に示すようにナット機能付き裏当メンバ8の縦枠部材3Aへの挿入動作を阻害しない退避姿勢Pと、ナット機能付き裏当メンバ8を使用位置に移動させた段階で開口部74の残余部分にはまり込む突っ張り姿勢Qとの間を回動するようにしている。また、回動端側には、一体に形成した弾性爪91を設けている。
【0039】
傾斜ボルト10は、縦枠材3Bに設けた座受要素たる座受部12によって頭部100を支持させて接合面320に対して軸心方向を略45度傾斜した方向に配したものである。座受部12は、図9から図12に示す第2の結合具Vのケーシング110に一体に設けたものである。具体的には、座受部12は、ケーシング110の上半部側に、傾斜ボルト10の軸心方向に直交するように傾斜させて設けた座受面12aと、この傾斜ボルト10の軸心方向に沿って設けたボルト挿入孔12bとから構成している。また、第2の結合具Vは、ケーシング110を主体に構成されたものである。このケーシング110は、アルミダイキャスト製のもので、縦枠材3B内に挿入可能な正面視L字形のブロック状をなし、このケーシング110の裏当面に第2の接合具位置決め孔70に係り合わせる係り合い突部13と、前記突条6に対応する切り欠き部14とを設けて縦枠材3Bの上端部分に取り付けられるようにしている(図12参照)。また、このボルト挿入孔12bを外側へ開放したボルト突出口115を設けて、傾斜ボルト10を外側へ突出できるようにしている。
【0040】
次に、上述の部材結合装置Cによって、縦枠材3Aと縦枠材3Bとを結合し、第1のパネル1Aと第2のパネル1Bとを連結する場合について説明する。
【0041】
まず、第1のパネル1Aの縦枠材3A側の空間S内には、上側の開口要素7bに対応させて第1の接合具Nを取り付けるようにする。まず、図7に示すようにナット機能付き裏当メンバ8のスライダ81を退避位置Mにするとともに突っ張りメンバ9を退避姿勢Pにして、開口部74に対して直交する方向に通過させて挿入し、該ナット機能付き裏当メンバ8を上方へ移動させつつ突っ張りメンバ9を突っ張り姿勢Q側へ回転させながら上方へ向かって挿入していく。そして、第1の接合具Nを縦枠材3Aの空間Sの内面に沿って上方の使用位置まで移動させ、使用位置まで移動させた段階で突っ張りメンバ9を、ナット機能付き裏当メンバ8と開口部74の下端部74bとの間に割り込ませ、移動禁止用段部8aを開口部74の上端部74aに当てるとともに、突っ張り部材9に設けた弾性爪91を開口部74の下端部74bに当てて一時的に弾性変形させつつ突っ張り姿勢Qにまで到達させて固定する。一方、第2のパネル1Bの縦枠材3B上端部近傍の空間S内に、第2の結合具Vを挿入し、切り欠き部14に前記突条6をはめ合わせるとともに、係り合い突部13を第2の結合具位置決め孔70に係り合わせることによって位置決めし、ねじ止めなど適宜の手段で固定して取り付ける。なお上述した第1の結合具Nおよび第2の結合具Vの装着時に、上下方向に渡って設けた突条6を、これら第1の結合具Nおよび第2の結合具Vをそれぞれ縦枠材3A、3Bの空間S内において上下移動させるための案内部として機能させることができる。
【0042】
そして、第2の結合具Vの座受部12のボルト挿入孔12bに傾斜ボルト10を挿入し、第2の結合具Vに設けたボルト突出口115,縦枠材3Bのボルト連通孔71、縦枠材3Aのボルト連通孔73、第1の結合具N側のボルト挿通孔83を順次通し、スライダ81に設けたねじ孔81aまで到達させて締め付けていく。この締め付けに伴い、スライダ81が案内穴82内を接合面320側に引き寄せられるとともに、爪部81bがナット機能付き裏当メンバ8に設けた爪部突出口84および縦枠材3Aに設けた開口部74を通過して接合面320から突出する。さらなる締め付けに伴って、この爪部81bの当て面81b1が、縦枠材3Bに設けた位置決め孔72の上端部72aと縦枠材3Aに設けた開口部74の上端部74aとに同時に当たり、これらの縦枠材3A、3Bはこの爪部81bの当て面81b1によって直接的に位置決めされる。一方、縦枠材3A、3Bの下端部側においては、爪を利用した図示しない係り合わせ機構を用いて結合する。しかして、縦枠材3Aと縦枠材3Bとが結合される。この際、本実施の形態においては、傾斜ボルト10を上方から接合面に対して斜めに挿入するようにしたので、パネル要素2を構造枠3に装着した状態でのまま、第1のパネル1Aと、第2のパネル1Bとを連結することができる。
【0043】
また、レイアウト変更などで、第1のパネル1Aを、第2のパネル1Bから変えて図13に示す第3のパネル1Cと連結させる場合は、第1の結合具Nの取り付け位置を変えて部材結合装置Cを再構成して、連結するようにする。なお、第3のパネル1Cは、縦枠材1A、1Bと異なる高さを有する縦枠材3Cを具備するものである。縦枠材3Cは、上述した縦枠材3Aおよび3Bと基本構造を同じくしたものであり、縦枠材3A、3Bと同じ部材には、特に詳述することなく同じ符号を付している。
【0044】
この場合は、まず、部材結合装置Cによるの縦枠材3A、3Bの結合を、傾斜ボルト1を弛めて解除し、下端部を結合している上記の図示しない係り合い機構を解除して、二つのパネル1A、1Bを離間させる。次に、第1のパネル1Aの縦枠材3Aの上側の開口要素7bに対応して取り付けた第1の結合具Nを、縦枠材3Aから取り外す。この際には、前記弾性爪91と開口部74の下端部74bとの係わり合いを解除し、突っ張りメンバ9を突っ張り姿勢Qから退避姿勢P側に回動させながら開口部74から外方へ取り出すようにする。そして、第1の結合具Nを、上述した上側の開口要素7bの開口部74への取り付け手順と同様に、下側の開口要素7bの開口部74に対して取り付ける。この第1の結合具Nと、第3のパネル1Cの縦枠材3Cの空間S内に取り付けた第2の結合具Vとから構成した部材結合装置Cによって、縦枠材1Aと、縦枠材1Cとを結合し、さらに下端部同士を上述した図示しない係り合い機構によって結合して、第1のパネル1Aと、第3のパネル1Cとを連結する。
【0045】
以上詳述したように、本実施形態の部材結合装置Cは、ずれ防止手段Zを設けたので、傾斜ボルト10によって、部材たる縦枠材3A、3Bを結合する際に生じるずれを防止して適正な結合をすることができる。
【0046】
さらに、ずれ止め要素Yを構成する爪部81bをスライダ81と一体に設けて、このスライダ81を挿入する時には、ナット機能付き裏当メンバ8の内部に退避位置Mに退避させ、挿入後に、このナット機能付き裏当メンバ8から突出位置Lに移動し得るように構成したので、該ナット機能付き裏当メンバ8を含む第1の結合具Nを縦枠材3Aの内部に挿入する際に邪魔にならず、結合する必要時にのみ突出させることができる。従ってこのようなものであれば、縦枠材3A、3Bの結合を解除した場合に、該ずれ止め要素が、第1のパネル1Aおよび第2のパネル1Bを厚み方向に移動するのを妨げず、すなわち、可動間仕切壁Wの中から第1のパネル1Aもしくは第2のパネル1Bのみを厚み方向にそって移動させ中抜きすることを可能にする。
【0047】
また、ずれ止め手段Zを、傾斜ボルト10の締め付け力を利用して、ずれ止め要素Yを構成する爪部81bを突出させるようにしたので、該爪部81bを突出させるための機構を別に設けなくともよく、構成を簡素なものにできる。
【0048】
さらに、この爪部81bをねじ孔81aを具備するスライダ81に一体に設けたので、部品点数を少なくできる。
【0049】
また、当て機構Tによって、爪部の当て面を縦枠材3Bに設けた位置決め孔72の上端部72aと、縦枠材3Aに設けた開口部74の上端部74aとに同時に当てて、両縦枠材3A、3Bの位置決めをこの爪部81bによって直接行うようにしたので、精度の高い適正な位置決めができる。
【0050】
さらに、当て機構Tによって、爪部81bの当て面81b1を、該爪部81bを最も突出させた場合には、移動禁止用段部8aに開口部74の上端部74aが接触しないようにしたので、移動禁止用段部8aを一体に設けたケーシング80に対して力が作用せず、該ケーシング80を、アルミのような加工や成形が簡単な金属によっても形成することができる。さらに、アルミダイキャスト以外に、合成樹脂により形成したものでもよく、コストの低減を図ることが可能である。
【0051】

BACKGROUND OF THE INVENTION
The present invention relates to a member coupling device preferably used when two members are coupled.
[0002]
[Prior art]
For example, as one type of movable partition wall constructed by connecting a plurality of panels, there is one in which vertical frame members constituting the structural frame of each panel are directly coupled using bolts.
[0003]
In such a type, for example, a nut element is provided on the vertical frame member of one panel, and a bolt inserted perpendicularly to the joint surface from the vertical frame member side of the other panel is tightened on the nut element. By wearing, the vertical frame members are joined together.
[0004]
[Problems to be solved by the invention]
However, when the bolts are fastened in the direction orthogonal to the joint surface as described above, the bolts are used, for example, in the case of connecting the vertical frame members of panels having different heights. If there is a member that prevents insertion of the bolt in a direction perpendicular to the joint surface, the bolt must be inserted avoiding the position, and the coupling position is limited.
[0005]
Therefore, it is conceivable to use an inclined bolt arranged in a direction inclined with respect to the joint surface. However, if this is the case, the vertical frame members are now relatively moved in the vertical direction. There is a possibility that it will shift.
[0006]
As a countermeasure for solving such a problem, for example, a positioning projection or claw portion is provided on the joint surface of one vertical frame member, and the projection or claw portion is provided on the joint surface of the other vertical frame member. It is conceivable that a positioning hole to be fitted is provided so that even if the bolts are tightened obliquely, the vertical frame members are not displaced from each other along the joint surface.
[0007]
However, if such protrusions and claw portions are provided in the vertical frame member, there arises a problem that the protrusions and claw portions become an obstacle when not in use. For example, in order to change the form of the constructed movable partition wall, there is a desire to extract or replace only the intermediate panel without disassembling the whole. However, when such protrusions and claw portions are fixedly present, there is a problem that even if the bolt is removed, the protrusions and claw portions interfere with each other so that only the intermediate panel cannot be removed.
[0008]
And such a malfunction may arise at the time of the combination of not only the vertical frame material of a panel but various members.
[0009]
[Means for Solving the Problems]
That is, the present invention has been made to solve the above problems, and is a member coupling device that couples two members by using an inclined bolt arranged in a direction inclined with respect to the joint surface. A backing member inserted into one member, a nut element provided on the backing member and engaged with an inclined bolt inserted from the other member side, and not provided on the backing member. A detent element that can sometimes be retracted to a position that does not get in the way, and a detent prevention means for projecting the detent element from the backing member after insertion and positioning the other member to prevent the deviating element are provided. The inclined bolt includes those that are inserted obliquely from above and those that are inserted obliquely from below.
[0010]
If it is such, it will become possible to prevent the up-down direction shift | offset | difference which arises by the coupling | bonding by an inclination volt | bolt by the detent | locking element which protrudes only when needed. Furthermore, by retracting the slip prevention element, the backing member can be smoothly inserted.
[0011]
Furthermore, in order to make a simple configuration without providing another mechanism for projecting the slip preventing element, the slip preventing means is configured to project the slip preventing element using the tightening force of the inclined bolt. It is desirable.
[0012]
As a specific embodiment of such a slip prevention means, the slip prevention means is provided with a slider having a nut element and an element for guiding the slider so that it can advance and retreat within a required range. Based on the movement of the slider according to the above, it may be configured to project the slip prevention element.
[0013]
In addition, in order to reduce the number of parts and simplify the configuration, a claw portion provided with a contact surface for positioning on the slider is integrally provided as a displacement preventing element, and a positioning portion is provided on the other member. It is desirable that the claw portion is protruded as the slider moves, and the other member is positioned by applying the contact surface of the claw portion to the positioning portion.
[0014]
In order to make positioning by such a claw part more accurate, it is configured so that the contact surface of the claw part can be simultaneously applied to the positioning parts of both members, and the positioning of the two members to be joined is clawed. It is desirable to carry out directly through the section.
[0015]
Further, when the backing member has a movement prohibiting step portion for prohibiting movement of the backing member at the use position, and the movement prohibiting step portion is configured to contact the positioning portion, In order to prevent a strong force from acting on the backing member from the member at the contact surface between the movement-inhibiting stepped portion and the positioning portion when the members are joined together, It is desirable to position the claw part so that it can be applied to the positioning part in preference to the movement-inhibiting step part when it is projected most. In such a case, the casing of the backing member may be molded with a material having low rigidity such as synthetic resin, and the degree of freedom in selecting the material of the casing is increased, and the cost can be reduced. .
[0016]
Moreover, when the force of a member is made to act on a nail | claw part in this way, it is desirable to shape | mold a nail | claw part with metals, such as iron, which have rigidity. If it is such, it will come to be able to use this nail | claw part repeatedly.
[0017]
In order to make the parts common and improve the convenience of manufacturing, it is desirable to provide a seating element that receives the head of the inclined bolt for insertion into the other member of the backing member. That is, by inserting the same backing member into each member, the members can be coupled to each other.
[0018]
As another aspect of the present invention, a backing member inserted into one member, a seat receiving element provided on the backing member for receiving the head of the inclined bolt, and provided on the other member side. A nut element that engages with the inclined bolt, a slip-off preventing element that is provided on the backing member and can be retreated to an unobstructed position when not needed, and the slip-off preventing element projects from the backing member after insertion to the other side. A member provided with a displacement prevention means for positioning the member to prevent the displacement can be used. In addition, as for the slip prevention means in such an aspect, what makes a nail | claw part protrude based on the pressing force concerning the seat element of a volt | bolt is mentioned, for example.
[0019]
Moreover, in order to utilize the member coupling device of the present invention more effectively, it is desirable that the backing member is configured to be detachable so that it can be replaced in various places.
[0020]
In addition, as a target member that effectively exhibits the effect of the member coupling device of the present invention, a vertical frame member that constitutes a structural member of the panel on which the panel element is mounted is desirable.
[0021]
Furthermore, if it is applied when joining vertical frame members having different heights, the effect is more effectively exhibited.
[0022]

It passes through the part 74 and protrudes from the joint surface 320. With further tightening, the contact surface 81b1 of the claw portion 81b simultaneously hits the upper end portion 72a of the positioning hole 72 provided in the vertical frame member 3B and the upper end portion 74a of the opening portion 74 provided in the vertical frame member 3A. These vertical frame members 3A and 3B are directly positioned by the contact surface 81b1 of the claw portion 81b. On the other hand, at the lower end side of the vertical frame members 3A and 3B, the vertical frame members 3A and 3B are coupled by using an engagement mechanism (not shown) using claws. Thus, the vertical frame member 3A and the vertical frame member 3B are joined. At this time, in the present embodiment, since the inclined bolt 10 is inserted obliquely from above with respect to the joint surface, the first panel 1A remains attached with the panel element 2 mounted on the structural frame 3. And the second panel 1B can be coupled.
[0043]
Further, when the first panel 1A is changed from the second panel 1B and connected to the third panel 1C shown in FIG. 13 due to a layout change or the like, the attachment position of the first coupler N is changed and the member is changed. The coupling device C is reconfigured and connected. The third panel 1C includes a vertical frame member 3C having a height different from that of the vertical frame members 1A and 1B. The vertical frame member 3C has the same basic structure as the vertical frame members 3A and 3B described above, and the same reference numerals are given to the same members as the vertical frame members 3A and 3B without detailed description.
[0044]
In this case, first, the vertical frame members 3A and 3B by the member coupling device C are released by loosening the inclined bolt 1, and the engagement mechanism (not shown) connecting the lower ends is released. The two panels 1A and 1B are separated from each other. Next, the first coupler N attached corresponding to the opening element 7b on the upper side of the vertical frame member 3A of the first panel 1A is removed from the vertical frame member 3A.
