Description

【０００１】
【発明の属する技術分野】
本発明は、手摺などの物品を壁面に取り付けるための物品固定具、物品の固定構造及び物品の固定方法に関する。
【０００２】
【背景の技術】
従来、壁面を構成する壁面構成部材に手摺などの物品を固定する場合、壁面構成部材は固定される物品を支持できる強度を有することが必要であるが、壁面構成部材が、柱間に設けられた合板に貼り付けられた石膏ボードなどのように、固比較的脆いものである場合、壁面構成部材の物品が取りつけられる面、つまり表面側から取り付けネジなどにより直接物品を固定して支持させることはできない。このため、壁面構成部材に壁面構成部材を貫通する開口部を形成し、この開口部よりアンカー部を挿通させて、該アンカー部を石膏ボードなどの壁面構成部材の裏面側で密着させた状態とし、この状態のアンカー部に物品を支持させている。なお、このときに壁面構成部材に形成される開口部は、アンカー部を表面側から挿通させるとともにアンカー部と表面側に配置されて物品が取り付けられる部位とを連結させるためのものであるため、極力小径であることが望ましい。
【０００３】
このように小径の開口部に挿通されるアンカー部を用いた物品固定具としては、例えば、開口部から挿入されるアンカー部を横方向に湾曲した２枚の略同形状の第１アンカー片及び第２アンカー片とし、第１アンカー片の基端部に、直交するように、開口部に挿通される取付ボルトの先端部を固定するとともに、第１アンカー片に隣接させて、第２アンカー片の基端部を回動自在に嵌合させ、これら第１及び第２アンカー片よりも取付ボルトの基端部側に、開口部を挿通不能な表面側部材と、この表面側部材が基端部側から抜けないようにロックナットが螺合されたものがある。
【０００４】
この物品固定具では、取付ボルトを軸を中心に回転させることで第１アンカー片も回転し、第１アンカー片は第２アンカー片に対して相対回転可能となっているとともに、これら第１アンカー片及び第２アンカー片とは互いに重なり合った状態で先端部側から開口部に挿通されるものとなっている。
よってこの物品固定具を壁面構成部材に取りつける際には、まず、第１及び第２アンカー片を重ねて畳んだ状態で開口部から壁面構成部材の裏面側に挿入して配置させる。そして、表面側から取付ボルトを回転させることで第１アンカー片を回動させて、第１及び第２アンカー片を開き、ロックナットを締め付けることで、第１及び第２アンカー片と開口部を挿通不能な表面側部材とで壁面構成部材を挟持させることで取り付けられる（例えば、特許文献１参照。）。
【０００５】
【特許文献１】
特開２００２−７０８１８号公報
【０００６】
【発明が解決しようとする課題】
ところで、上記特許文献１の構成では、物品固定具を壁面構成部材に取り付ける場合、第１及び第２アンカー片を壁面構成部材の裏面側に配置した後、表面側にて取付ボルトを回動操作して第１アンカー片を回動させて、第１アンカー片と第２アンカー片とを開かせる際に、表面側で取付ボルトの回転操作では、壁面構成部材の裏面側にて実際に両アンカー片が例えば１８０°の角度で好適に開いているかどうか確認することができず、開くべき角度（１８０°）を前記壁面構成部材の裏面側で感覚的に回動操作することで行っている。
このため、取付ボルトを操作することで第１アンカー片を所定角度回転させて、該第１アンカー片が第２アンカー片に対して所定角度１８０°開くように回転させたつもりが、実際には、第１アンカー片の回転に伴い第２アンカー片が伴って回転し、意図した所定角度１８０°で開いていない状態が生じたり、また所定角度１８０°以上に開いてしまう状態が生じる。
この状態で、ロックナットを締めて表面側部材とで壁面構成部材を挟持してしまうと、その際に壁面構成部材の表面側でボルトに基端部に物品を取り付けた際に、アンカー片により確実に物品を支持させることができない。
【０００７】
また、壁面構成部材に固定する際に、第１及び第２アンカー片を重ね、湾曲方向に沿って開口部からねじり込むように深く挿入していき、基端部部分で湾曲方向と直交する取付ボルトを該取付ボルトの軸方向に突っ込むようにして挿入していくため、その取り付けに手間がかかる。
本発明の課題は、壁面構成部材を構成する面材に、手間がかからず容易に取り付けることができるとともに、面材に設けられた開口部から挿入して面材の裏面側に配置されるアンカー部を介して面材に、物品を確実に支持させるように固定することである。
【０００８】
【課題を解決するための手段】
以上の課題を解決するため、請求項１記載の発明は、例えば、図１〜図４に示すように、
面材（例えば、合板１５，石膏ボード１６等からなる面材１）に形成された開口部１１より挿入され、前記面材１の裏面１７側に配置されるアンカー部３と、該アンカー部３に接続され、前記開口部１１に挿通されるボルト４と、該ボルト４が挿通されるとともに前記開口部１１に挿入され、当該開口部１１を閉塞するスペーサ部５とを有し、前記ボルト４に前記面材１の表面１３側で物品（例えば手摺用ブラケット８）が取りつけられることで前記ボルト４を介して前記物品８と前記アンカー部３とで前記面材１を挟持して前記物品８を面材１に固定する物品固定具２において、
前記アンカー部３は、互いに重なった状態で先端部（３１ｂ，３２ｂ）側から前記開口部１１より前記面材１の裏面１７側に挿入されるとともに、それぞれの基端部３１ａ，３２ａが前記ボルト４に接続され、前記ボルト４を軸廻りに回転させることで相対的に回転して開き、それぞれの先端部が前記面材１の裏面１７に当接可能な２枚の羽根部（例えば、第１アンカー片３１，第２アンカー片３２）を備え、
前記２枚の羽根部３１，３２は、それぞれ前記開口部１１に挿入可能な幅を有する長尺な直線状の平板状部材からなるとともに、前記２枚の羽根部３１，３２どうしには、当該２枚の羽根部３１，３２が所定角度（例えば１８０°）で開いた状態で前記ボルト４を表面１３側に引くことで互いに係合し、前記２枚の羽根部３１，３２どうしの相対的な回転を抑止する係合部（例えば係合突起３６）及び被係合部（例えば切欠部３５）が形成され、
前記スペーサ部５は、前記ボルト４に、該ボルト４の軸方向に移動自在に螺合されるとともに、前記開口部１１に挿入された際に、当該開口部１１の表面側の縁部に係止されるフランジ部５４を備えることを特徴とする。
【０００９】
請求項１記載の発明によれば、前記開口部１１に挿通されるボルト４に接続され且つ、前記面材１の裏面１７側に配置されるアンカー部３が、前記２枚の羽根部３１，３２を備えるので、前記２枚の羽根部３１，３２を互いに重なった状態で先端部（３１ｂ，３２ｂ）側から前記開口部１１より前記面材１の裏面１７側に挿入した後で、前記開口部１１に挿通された前記ボルト４を表面側で軸廻りに回転させることで相対的に回転させて所定角度開かせて、前記ボルト４を表面１３側に引き、前記２枚の羽根部３１，３２どうしにそれぞれ形成された係合部３６と被係合部３５とを互いに係合させることで、前記２枚の羽根部３１，３２どうしの相対的な回転が抑止された状態、すなわち、両羽根部３１，３２が開いた状態が保持されたままの状態で前記面材１の裏面１７に当接させることができる。つまり、表面１３側からのボルト４の回動操作でも、ボルト４をある程度回転させて引いた際にボルトを引けない場合は、前記係合部３６と被係合部３５とは係合されていない状態であり、引けた場合は両者が係合しているものと判断することができ、前記表面側からでも前記２枚の羽根部３１，３２が所定角度開いた状態であるか否かを確認することができ、裏面側で２枚の羽根部を所定角度開かせる作業を容易に行うことができる。
【００１０】
このように前記２枚の羽根部３１，３２を所定角度開いて保持させた状態で、前記面材１の表面１３側において、前記ボルト４に物品８を取り付けることで、前記ボルト４を介して、所定角度開いた２枚の羽根部３１，３２とで前記面材１を強固に挟持することができ、物品８を前記面材１に確実に強固に固定することができる。よって、壁面構成部材等を構成する面材に、手間がかからず容易に取り付けることができるとともに、面材に設けられた開口部から挿入して面材の裏面側に配置されるアンカー部を介して面材に、物品を確実に支持させるように固定することができる。
【００１１】
また、２枚の羽根部３１，３２は、それぞれ前記開口部１１に挿入可能な幅を有する長尺な直線状の平板状部材からなるので、これら２枚の羽根部３１，３２を重ね合わせて前記面材１の開口部１１内に、先端部３１ｂ，３２ｂ側から容易に挿入することができるとともに、前記面材１の裏面１７側で開かせた状態のときには、面接触にて前記面材１の裏面１７に当接させることができ、前記ボルトを介して該ボルトに取り付けられる物品８とで前記面材１を挟持した際に、前記物品８を支持する支持力を前記面材１から確実に得ることができる。
【００１２】
さらに、前記ボルト４には前記開口部１１に挿通され、前記アンカー部３と取りつけられるべき物品８との間に介在されるスペーサ部５が設けられているので、このスペーサ部５により、前記アンカー部３と前記物品８とで挟持される面材１の開口部１１を閉塞することができる。
【００１３】
加えて、前記スペーサ部５には、前記開口部１１に挿入された際に、当該開口部１１の表面側の縁部に係止されるフランジ部が形成されているので、前記２枚の羽根部を備えるアンカー部３を前記開口部１１を介して前記面材１の裏面１７側に配置した後で、前記ボルトを介して前記２枚の羽根部３１，３２を所定角度開き、前記面材１の裏面に当接させた状態で、前記スペーサ部５を前記面材１側に押圧して前記開口部１１内に挿入することで、前記開口部１１を略完全に閉塞することができる。また、前記スペーサ部５は、前記ボルト４に該ボルト４の軸方向に移動自在に螺合されているので、前記２枚の羽根部を備えるアンカー部３を前記開口部１１を介して前記面材１の裏面１７側に配置した後で、前記ボルトを介して前記２枚の羽根部３１，３２を所定角度開き、前記面材１の裏面に当接させた状態で、前記スペーサ部５を前記面材１側に移動させて、前記フランジ部５４を前記開口部１１の表面側の縁部に当接させることで、前記面材１に対する物品固定具２の仮固定を行うことができる。これにより、ボルト４に表面側で物品８を取り付ける際の作業を容易に行うことができる。
【００１４】
請求項２記載の発明は、請求項１記載の物品固定具において、例えば、図１及び図４に示すように、
２枚の羽根部（例えば第１アンカー片３１，第２アンカー片３２）は、それぞれ前記面材１の裏面１７に当接する当接面３１１，３２１を有し、
前記当接面３１１，３２１は、前記２枚の羽根部３１，３２が前記ボルト４に接続された基端部３１ａ，３２ａより、ボルト４の基端部４ｂ側に配置されていることを特徴とする。
【００１５】
請求項２記載の発明によれば、２枚の羽根部３１，３２がそれぞれ備える前記当接面３１１，３２１が、前記２枚の羽根部３１，３２が前記ボルト４に接続された基端部３１ａ，３２ａより、ボルト４の基端部４ｂ側に配置されているので、ボルト４を介して該ボルト４に表面側で取り付けられた物品８とで前記面材１を挟持する際に、前記２枚の羽根部３１，３２にはボルト４を介して前記面材の表面側に引かれることとなり、その際、前記当接面３１１，３２１を前記面材１の裏面１７に完全に密着させることができる。よって、前記物品８を前記面材に確実に支持固定させることができる。
【００１６】
請求項３記載の発明は、請求項１または２記載の物品固定具において、例えば図１及び図５に示すように、
スペーサ部５は、前記アンカー部３側への軸方向の外力により押圧されることで軸方向に縮むように形成されていることを特徴とする。
【００１７】
請求項３記載の発明によれば、スペーサ部５は、前記アンカー部３側への軸方向の外力により押圧されることで軸方向に縮むように形成されているので、前記２枚の羽根部を備えるアンカー部３を前記開口部１１を介して前記面材１の裏面１７側に配置し、前記ボルトを介して前記２枚の羽根部３１，３２を所定角度開き、前記面材１の裏面に当接させるとともに、前記スペーサ部５を前記開口部１１内に挿入した後で、前記ボルト４に物品を取り付けることで、該物品と前記２枚の羽根部とで面材を挟持させる際に、前記スペーサ部５に前記物品８の前記面材側への力が加わるとともに、前記アンカー部３側から軸方向に外力が加わることで縮み、前記物品８は前記面材１の表面１３に確実に密着した状態となるとともに、前記アンカー部３とで確実に固定された状態となる。
【００１８】
請求項４記載の発明は、請求項１または２記載の物品固定具において、例えば、図１〜図４に示すように、２枚の羽根部３１，３２のうちの一方の羽根部３１の基端部３１ａは、前記ボルト４に、前記一方の羽根部３１が前記ボルト４と一体回転するように固定され、他方の羽根部３２の基端部３２ａは前記ボルト４に回転自在に挿通されて、前記一方の羽根部３１に対して相対回転可能とされてなり、
前記他方の羽根部３２の基端部３２ａには、先端方向と逆方向に延出され、前記面材１に形成された開口部１１に挿入されて前記面材１の裏面１７側に配置された際に、前記他方の羽根部３２の先端部３２ｂとともに前記裏面１７に当接可能な延出部３４が形成されていることを特徴とする。
【００１９】
請求項４記載の発明によれば、互いに重なった状態で先端部３１ｂ，３２ｂ側から前記開口部１１より前記面材１の裏面１７側に挿入される２枚の羽根部のうち、他方の羽根部３２の基端部３２ａには、先端方向と逆方向に延出され、前記面材１に形成された開口部１１に挿入されて前記面材１の裏面１７側に配置された際に、前記他方の羽根部３２の先端部３２ｂとともに前記裏面１７に当接可能な延出部３４が形成されているので、物品固定具２を面材１に取り付ける際に、前記アンカー部３の有する２枚の羽根部３１，３２を前記開口部１１に挿入して、前記面材１の裏面１７側に配置させるとともに前記ボルト４を前記開口部１１に挿通させた後、前記延出部３４を前記先端部３２ｂとともに前記面材１の裏面１７に当接可能となる。
【００２０】
これにより、物品を固定するために物品固定具２を前記面材に取り付け作業中に、前記面材１の裏面１７側に配置させたアンカー部３のうち、前記他方の羽根部３２において、前記先端部３２ｂと延出部３４とが、前記ボルト４に回転自在に挿通された前記基端部３２ａを挟んで前記面材１の裏面１７に当接することで、前記アンカー部３が前記表面側に抜けにくくなり、前記スペーサ部５を前記開口部１１内に挿入したり、物品を前記ボルト４に前記面材の表面側で取り付けたり等の物品を固定するための作業を容易に行うことができる。
また、前記スペーサ部５を前記開口部１１に挿入した際に、前記延出部３４が、前記面材１の裏面に当接可能に前記基端部３２ａに形成されていれば、前記スペーサ部５を前記アンカー部３側にねじ込むことで前記フランジ部５４を前記面材１の表面側の開口縁部に当接させて、前記延出部３４は前記先端部２３ｂとともに前記フランジ部５４とで前記面材１を挟持することができ、これにより、前記物品固定具２は仮止めされ、前記一方の羽根部３１を回転させて２つの羽根部３１，３２を開く作業や、前記ボルト４に物品８を取り付ける作業等を容易に行うことができる。
【００２１】
請求項５記載の発明は、請求項１〜４のいずれか一項に記載の物品固定具により物品を面材に固定した物品の固定構造において、例えば図１に示すように、
前記係合部（例えば係合突起３６）及び被係合部（例えば切欠部３５）が係合した前記アンカー部３の２枚の羽根部（例えば、第１アンカー片３１，第２アンカー片３２）が、所定角度（例えば１８０°）開いた状態で前記面材１の裏面１７に当接され、
前記２枚の羽根部３１，３２の基端部３１ａ，３２ａに接続されたボルト４が前記開口部１１に挿通され、
前記ボルト４が挿通された前記スペーサ部５が、そのフランジ部５４を前記開口部１１の表面１４側の縁部に係止させた状態で前記開口部１１内に挿入され、前記ボルト４に前記面材１の表面１３側で物品（例えば、手摺用ブラケット８）が取り付けられ、
前記ボルト４を介して前記物品８と前記アンカー部３とで前記面材１を挟持することで、前記物品８は前記面材１に固定されていることを特徴とする。
【００２２】
請求項５記載の発明によれば、前記開口部１１に挿入された前記スペーサ部５を挿通するボルト４を介して、前記係合部３６及び被係合部３５が係合し、且つ所定角度開いた状態で前記面材１の裏面１７に当接された前記アンカー部３の２枚の羽根部３１，３２と、前記ボルト４に前記面材１の表面１３側で取り付けられた物品８とで前記面材１を挟持することで、前記物品８が前記面材１に固定されているので、前記物品８はその支持力を、ボルト４と、所定角度開いた状態で且つ前記面材１に当接した前記２枚の羽根部３１，３２とを介して面材１から得ることができ、前記スペーサ部５により前記開口部１１を閉塞した状態で、前記物品を、前記面材１に強固に固定された状態とすることがができる。
【００２３】
このとき、前記物品固定具２が、請求項３の物品固定具であれば、前記スペーサ部５が、前記アンカー部側への軸方向の外力により押圧されることで軸方向に縮むように形成されているので、前記スペーサ部は、前記面材１の開口部１１内にて前記アンカー部３と前記物品との間に介在しているので、前記ボルト４を介して、前記アンカー部３と物品８とで面材１を挟持する際に、前記物品により前記アンカー部側に押圧されて縮み、前記アンカー部３と前記物品８とで挟まれる前記面材１の厚みに対応した長さとなり、前記開口部１１を略完全に密閉した状態とすることができる。
【００２４】
また、前記物品固定具２が、請求項４の物品固定具であれば、物品固定具２を面材１に取り付ける際に、前記アンカー部３の有する２枚の羽根部３１，３２を前記開口部１１に挿入して、前記面材１の裏面１７側に配置させるとともに前記ボルト４を前記開口部１１に挿通させた後、前記延出部３４を前記先端部３２ｂとともに前記面材１の裏面１７に当接可能となる。
これにより、物品を固定するために物品固定具２を前記面材に取り付け作業中に、前記面材１の裏面１７側に配置させたアンカー部３のうち、前記他方の羽根部３２において、前記先端部３２ｂと延出部３４とが、前記ボルト４に回転自在に挿通された前記基端部３２ａを挟んで前記面材１の裏面１７に当接することで、前記アンカー部３が前記表面側に抜けにくくなり、前記スペーサ部５を前記開口部１１内に挿入したり、物品を前記ボルト４に前記面材の表面側で取り付けたり等の物品を固定するための作業を容易に行うことができる。
【００２５】
また、前記スペーサ部５を前記開口部１１に挿入した際に、前記延出部３４が、前記面材１の裏面に当接可能に前記基端部３２ａに形成されていれば、前記スペーサ部５を前記アンカー部３側にねじ込むことで前記フランジ部５４を前記面材１の表面側の開口縁部に当接させて、前記延出部３４は前記先端部２３ｂとともに前記フランジ部５４とで前記面材１を挟持することができ、これにより、前記物品固定具２は仮止めされ、前記一方の羽根部３１を回転させて２つの羽根部３１，３２を開く作業や、前記ボルト４に物品８を取り付ける作業等を容易に行うことができる。
そして、前記アンカー部３では、前記２枚の羽根部３１，３２が開いた際に、前記２枚の羽根部３１，３２の先端部３１ｂ，３２ｂとともに、他方の基端部３２ａの延出部３４が前記面材１の裏面１７に当接しているので、前記アンカー部３が接続されたボルト４に、前記面材１の表面側で取り付けられて前記アンカー部３とで面材１を挟持することで、該面材１に固定される物品８は、前記２枚の羽根部３１，３２の先端部３１ａ，３２ａ及び延出部３４を介して前記面材１からその支持力を得ることができ、確実に強固に固定されるものとなる。
【００２６】
請求項６記載の発明は、請求項３記載の物品固定具を用いて面材に物品を固定する物品の固定方法において、例えば、図７〜図１３に示すように、
前記面材（例えば合板１５及び石膏ボード１６よりなる面材１）に開口部１１を形成し、
次いで、前記開口部１１に、前記２枚の羽根部３１，３２を互いに重ねた状態で、先端部３１ｂ，３２ｂ側から挿入して前記アンカー部３を前記面材１の裏面１７側に配置するとともに、前記開口部１１に前記ボルト４を挿通し、
次いで、前記ボルト４が挿通されたスペーサ部５を前記開口部１１内に配置し、
次いで、前記面材１の表面１３側から前記ボルト４を軸回りに回転させることで前記２枚の羽根部３１，３２を、相対的に回転させて所定角度（例えば１８０°）で開いた状態とし、
次いで、前記ボルト４を前記面材１の表面１３側に引くことで、前記２枚の羽根部３１，３２どうしの係合部３６と被係合部３５とを係合させて、前記２枚の羽根部３１，３２を前記面材１の裏面１７に当接させ、
次いで、前記ボルト４に、該ボルト４が挿通された前記スペーサ部５に隣接するように前記面材１の表面１３側で物品８を取りつけて、前記ボルト４を介して前記物品８と前記アンカー部３とで前記面材１を挟持することで前記スペーサ部を軸方向に縮ませることを特徴とする。
【００２７】
請求項６記載の発明によれば、前記面材１に形成された前記開口部１１に、前記２枚の羽根部３１，３２を互いに重ねた状態で、先端部３１ｂ，３２ｂ側から挿入して前記アンカー部３を前記面材１の裏面１７側に配置するとともに、前記開口部１１に前記ボルト４を挿通し、次いで、前記スペーサ部５を前記開口部１１内に配置し、次いで、前記面材１の表面１３側から前記ボルト４を軸回りに回転させることで前記２枚の羽根部３１，３２を、相対的に回転させて所定角度（例えば１８０°）で開いた状態とし、次いで、前記ボルト４を前記面材１の表面１３側に引くことで、前記２枚の羽根部３１，３２どうしの係合部３６と被係合部３５とを係合させて、前記２枚の羽根部３１，３２を前記面材１の裏面１７に当接させ、次いで、前記スペーサ部５に隣接するように前記面材１の表面１３側で前記ボルト４に物品８を取りつけて、前記ボルト４を介して前記物品８と前記アンカー部３とで前記面材１を挟持することで前記スペーサ部を軸方向に縮ませるので、前記物品８を前記面材１に固定するための物品固定具２を前記面材１に、前記２枚の羽根部３１，３２を確実に開かせて前記面材１の裏面１７に当接させた状態で容易に取り付けることができるとともに、取り付けられた２枚の羽根部３１，３２と、前記物品８とともに前記面材１を強固に挟持することで、前記物品８を前記面材１に確実に固定することができる。
【００２８】
また、前記２枚の羽根部３１，３２と前記物品８とで前記面材１を挟持する際に、前記２枚の羽根部３１，３２と前記物品８との間に介在するスペーサ部５は、前記物品８の前記アンカー部３側に引き寄せられる力により軸方向に縮ませられるので、前記スペーサ部５は前記物品８及びアンカー部３とで挟まれる前記面材１の前記開口部１１に対応する厚みとなり、前記開口部１１を確実に閉塞された状態とすることができる。

請求項７記載の発明は、請求項４記載の物品固定具を用いて面材に物品を固定する物品の固定方法において、例えば、図７〜図１３に示すように、
前記面材（例えば合板１５及び石膏ボード１６よりなる面材１）に開口部１１を形成し、
次いで、前記開口部１１に、前記２枚の羽根部３１，３２を互いに重ねた状態で、先端部３１ｂ，３２ｂ側から挿入して前記アンカー部３を前記面材１の裏面１７側に配置するとともに、前記開口部１１に前記ボルト４を挿通し、
次いで、前記ボルト４が挿通されたスペーサ部５を前記開口部１１内に配置し、
次いで、前記面材１の表面１３側から前記ボルト４を軸回りに回転させることで前記２枚の羽根部３１，３２を、相対的に回転させて所定角度（例えば１８０°）で開いた状態とし、
次いで、前記ボルト４を前記面材１の表面１３側に引くことで、前記２枚の羽根部３１，３２どうしの係合部３６と被係合部３５とを係合させて、前記２枚の羽根部３１，３２を前記面材１の裏面１７に当接させ、
次いで、前記ボルト４に、該ボルト４が挿通された前記スペーサ部５に隣接するように前記面材１の表面１３側で物品８を取りつけて、前記ボルト４を介して前記物品８と前記アンカー部３とで前記面材１を挟持することを特徴とする。
【００３０】
請求項７記載の発明によれば、前記面材１の開口部１１に、前記２枚の羽根部３１，３２を互いに重ねた状態で、先端部３１ｂ，３２ｂ側から挿入して前記アンカー部３を前記面材１の裏面１７側に配置するとともに、前記開口部１１に前記ボルト４を挿通した際に、前記面材１の裏面１７側に配置されたアンカー部３の互いに重なった状態の２枚の羽根部３１，３２のうち他方の羽根部３２は、その先端部３２ｂとともに、基端部３２ａに設けられた延出部３４を前記面材１の裏面に当接可能となっており、次いで、前記ボルト４が挿通されたスペーサ部５を前記開口部１１内に配置する際に、前記他方の羽根部３２の先端部３２ｂ及び延出部３４とが前記面材１の裏面に当接することで、アンカー部３自体が前記面材１の表面１７に抜けにくくなるので、前記スペーサ部５の前記開口部１１への配置作業を容易に行うことができる。
【００３１】
そして、前記面材１の表面１３側から前記ボルト４を軸回りに回転させることで前記２枚の羽根部３１，３２を、相対的に回転させて所定角度（例えば１８０°）で開いた状態とし、前記ボルト４を前記面材１の表面１３側に引くことで、前記係合部３６と前記被係合部３５とを係合させて、前記２枚の羽根部３１，３２を前記面材１の裏面１７に当接させ、次いで、前記スペーサ部５に隣接させて前記面材１の表面１３側で前記ボルト４に物品８を取りつけて、前記ボルト４を介して前記物品８と前記アンカー部３とで前記面材１を挟持することで、前記物品８を前記面材１に固定できる。
前記面材１に固定された物品８は、前記面材１の裏面に前記一方の羽根部３２の先端部３１ａと、前記他方の羽根部３２の先端部３２ａとともに他方の羽根部３２の延出部３４とが当接していることから、前記面材１から確実に支持力を得た状態で強固に固定されたものとなる。

【発明の実施の形態】
以下、図を参照して本発明の実施の形態を詳細に説明する。
まず、構成を説明する。
図１では、壁面を構成する面材１に開口部１１が形成され、この開口部１１に挿通された物品固定具２を介して、面材１の取付面（以下、表面）１３側に配置された物品としての手摺用ブラケット８が、取付面１３に固定されている。
【００３３】
壁面を構成する面材１は、縦横の框材を矩形枠状に組み付けてなる枠体の表裏面に合板を設けてなる壁パネルの表面側の合板１５と、該合板１５に貼設された石膏ボード１６とからなり、開口部１１は鉛直方向に立設された合板１５及び石膏ボード１６に、該合板の裏面と石膏ボード１６の表面１３とに略水平方向に貫通するように形成されている。
【００３４】
物品固定具２は、図１〜図５に示すように、面材１の裏面側に配置され、面材１の裏面１７に当接するアンカー部３と、開口部１１内に、先端部４ａ及び基端部４ｂが面材１の裏面１７及び表面１３からそれぞれ突出した状態で水平に挿通され、面材１の裏面側の先端部４ａでアンカー部３に接続されたボルト４と、ボルト４に螺合されるとともに面材１の表面側から開口部１１に挿入されて該開口部１１内に嵌合されるスペーサ部５と、ボルト４に挿通される調整スペーサ５０と、面材１の表面側から突出したボルト４の基端部４ｂに、ブラケット８の固定部８１を介して螺合されたナット６等とを備える。
【００３５】
アンカー部３は、図１〜図４に示すように、開口部１１を介して表面側から面材１の裏面側に挿入可能に構成された長尺板状をなす第１アンカー片３１と、この第１アンカー片３１と平面視略同形状をなす第２アンカー片３２等とを有する。なお、第１アンカー片３１及び第２アンカー片３２は、それぞれ数ｍｍ厚の剛性に優れた金属材料（例えば鋼板）や合成樹脂（繊維強化された合成樹脂を含む）などにより形成されていることが望ましい。
【００３６】
第１アンカー片３１は、その基端部３１ａにネジ孔３１ｃが形成され、このネジ孔３１ｃにボルト４の先端部４ａを螺合することで、第１アンカー片３１自体がボルト４の軸方向と直交するように固定されている。第１アンカー片３１は、ボルト４を軸心を中心に回転させることで一体的に回転し、先端部３１ｂが基端部３１ａを支点に旋回自在となっている。
【００３７】
また、この第１アンカー片３１の先端部３１ｂには、面材１の裏面１７に当接する当接面３１１が設けられ、この当接面３１１は、第１アンカー片３１の基端部３１ａの裏面よりボルト４の基端部側に配置されている。
つまり、この第１アンカー片３１には、基端部３１ａに連続して屈曲部３１ｄが設けられていることで先端部３１ｂは、基端部３１ａよりも裏面側に位置するものとなっている。さらに、この第１アンカー片３１の基端部３１ａは軸心廻りの外縁部分に、第２アンカー片３２の係合突起３６が係合可能な切欠部（被係合部）３５が形成されている。切欠部３５は、第１アンカー片３１の側辺部を構成する基端部３１ａの外縁部に、平面視してネジ孔３１ｃと隣り合う位置に形成されている。
【００３８】
第２アンカー片３２は、図１〜図４に示すように、第１アンカー片３１と平面視略同形状に形成されてなり、基端部３２ａには、ボルト４が挿通されるボルト挿通孔３２ｃが形成されている。
第２アンカー片３２は、ボルト挿通孔３２ｃにボルト４を挿通することで、ボルト４の先端部４ａにて、第１アンカー片３１と隣合う位置で、ボルト軸心を中心に回動自在に接続され、第１アンカー片３１に対して相対的に回転自在となっている。
【００３９】
また、この第２アンカー片３２の先端部３２ｂには、面材１の裏面１７に当接する当接面３２１が設けられ、この当接面３２１は、第２アンカー片３２自体が屈曲部３２ｄで屈曲してなることで、基端部３２ａの裏面と比してほぼ平行な異なる平面上に配置されている。図４では、当接面３２１は基端部３２ａの裏面と長さＬ分ずれた平面に位置したものとなっている。これにより、当接面３２１は、ボルト４に接続した際に、基端部３２ａよりも、ボルト４の基端部側、言い換えれば面材１側に配置された状態となっている。
【００４０】
また、第２アンカー片３２の基端部３２ａには、先端方向と逆方向に延出され、面材１に形成された開口部１１に挿入されて面材１の裏面１７側に配置された際に、第２アンカー片３２の先端部３２ｂとともに裏面１７に当接可能な延出部３４が形成されている。
さらに、第２アンカー片３２の基端部３２ａには、第１アンカー片３１に対向する面に、該第１アンカー片に向かって突出し、第２アンカー片３２及び第１アンカー片３１が相対的に回転することで、軸心を中心に所定角度開いた際に、第１アンカー片３１の切欠部（被係合部）３５に係合する係合突起３６が形成されている。
ここでは所定角度とは、略１８０°となっており、第１アンカー片３１及び第２アンカー片３２が相対的に回転することで平面視略直線状のものとなる。
係合突起３６は、第２アンカー片３２を第１アンカー片３１と重ね合わせた際に、第２アンカー片３２の基端部３２ａにおいて、ネジ孔３２ｃを挟んで、第１アンカー片３１の切欠部３５とは反対側の位置に設けられている。
そして、第１アンカー片３１及び第２アンカー片３２とを相対的に回転させて１８０°開いた状態にすることで、係合突起３６は軸方向で切欠部３５と重なった位置となるように形成されている。
【００４１】
このようにボルト４の先端部４ａに接続された第１アンカー片３１及び第２アンカー片３２を有するアンカー部３では、自重によりボルト４から垂下された状態で互いに重なり合う。このとき、第１アンカー片３１の当接面３１１が第２アンカー片３２の先端部３２ｂの表面に当接し、第１アンカー片３１の基端部３１ａの裏面と、第２アンカー片３２の基端部３２ａの表面との間に係合突起３６が配置されたものとなっている。そして、ボルト４を軸回りに回動させることで、第１アンカー片３１が基端部３１ａを支点に回動して、第２アンカー片３２と相対的に回転することとなり、第１アンカー片３１及び第２アンカー片３２は開くことになる。
【００４２】
スペーサ部５は、開口部１１の開口径と略同一の外径を有する中空の円柱状体であり、軸方向に縮小（縮み）可能な縮小部５１を備える略筒状の本体部５ａと、本体部５ａの軸方向の開口部を閉塞する上面部５ｂと底面部５ｃとを備える。縮小部５１は、開口部１１の開口径と略同一の外径を有し、本体部５ａを構成する筒状の周壁の一部を周方向に沿って内側にＶ字状に窪ませてなる断面視Ｖ字状の窪み部分５１ａとこのＶ字状の窪み部分５１ａに所定間隔を空けて形成された開口部５１ｂとで形成されている。
【００４３】
これによりスペーサ部５は、軸方向に上面部５ｂ及び底面部５ｃを接近させる外力を加えることで、縮小部５１の窪み部分５１ａでは、Ｖ字の頂点部分を中心とするＶ字の角度の幅が狭くなり、外径の大きさが変わることなく、本体部５ａが軸方向に潰れ、スペーサ部５自体の軸方向の長さが短くなるように構成されている。
上面部５ｂ及び底面部５ｃには、それぞれボルト４が挿通される挿通孔５２，５３が形成され、上面部５ｂに形成された挿通孔５２は上面部５ｂの中央部にバーリング加工を施することで形成され、バーリング加工によりなる筒状のリブ５２ａの内面にタップを切ることでボルト４と螺合するものとなっている。
【００４４】
また、底面部５ｃに形成された挿通孔５３は、ボルト４が遊嵌可能な径を有しており、この底板部５ｃの周縁部には、本体部５ａの外径から放射方向に張り出したフランジ部５４が形成されている。
このフランジ部５４は、スペーサ部５を開口部１１に挿入した際に、面材１の表面１３の開口縁部に係止されるものとなっている。
【００４５】
さらに、底面部５ｃには、ボルト４に螺合されたスペーサ部５を回動させるための治具４４が取り付け可能な穴５６，５６が、挿通孔５３を挟んで、スペーサ部５の軸方向と平行に開口して形成されている。
この穴５６，５６は、図５（ｄ）に示すように、治具４４としての特殊スパナ４４の突出棒４４ａ，４４ａが後方から挿入されるものである。
特殊スパナ４４は、板材の中央部分を屈曲させて鈎状をなし、突出棒４４ａが突設された先端部ｂと、先端部の基端部に一端部が直交して接合された中央部４４ｃと、中央部の他端部に、先端部４４ｂの延在方向と逆方向に延在するように直交して接合され、操作部となる基端部４４ｄとを有する。
先端部４４ｂには、ボルト４が挿通可能な挿通孔４４ｅが形成され、この先端部４４ｂにおける突出棒４４ａと、挿入孔４４ｅとの配置関係は、底板部５ｃにおける穴５６、５６と挿通孔５３との配置関係に対応している。
そして、ボルト４が挿通されたスペーサ部５に対して特殊スパナ４４を取り付ける際には、先端部４４ｂの挿通孔４４ｅをボルト４に挿通させるとともに、突出棒４４ａを穴５６に挿入する。そして、基端部４４ｄをボルト４の軸を中心に回動させることでスペーサ部５をボルト４の軸方向に移動させることができる。つまり、スペーサ部５にボルト４が挿通されている際に、スペーサ部５の底面５ｃ側の回動操作で、スペーサ部５を軸回転させて、ボルト４軸上を移動させることができる。
【００４６】
調整スペーサ５０は、スペーサ部５とともに挿入される面材１の厚みに合わせて備えるものであり、開口部１１の内径と略同一の外径を有する筒状に形成され、中央にボルト４が挿通される貫通孔が形成されている。つまり、スペーサ部５の厚み（高さ）が石膏ボード１６の厚みと略じ長さとなっているため、石膏ボード１６とで面材１を構成する合板１５の厚みに合わせた厚み（高さ）としており、第２アンカー片３２とスペーサ部５との間に介在した状態でボルト４に挿通されている。
【００４７】
面材１に取り付けられる物品としての手摺用ブラケット８は、面材１に固定して手摺が取り付けられるものであり、面材１の表面１３に当接した状態で固定される固定部８１と、固定部８１を貫通して形成されボルト４が挿通される貫通孔８２と、固定部８１から湾曲して上方に伸びるとともに先端部に手摺が取り付けられるアーム部８４等とを備える。
固定部８１は、開口部１１を完全に覆うとともに開口部１１の周囲の面材表面１３を覆う固定面８１ａを有し、この固定面８１ａは貫通孔８２と連通している。また、この固定面８１ａには貫通孔８２と連通し、面材１に当接した際に、面材１の開口部１１に挿入されたスペーサ部５のフランジ部５４が内嵌される座掘部８５が形成されている。
【００４８】
このように構成されたブラケット８が物品固定具２により面材１に固定されている。すなわち、図１に示すように、面材１の裏面側に配置された第１アンカー片３１及び第２アンカー片３２が基端部３１ａ，３２ａからそれぞれ上下に延在するように配置され、それぞれの当接面３１１，３２１が開口部１１上下の合板１５の裏面１７に当接している。そして、これら第１アンカー片３１及び第２アンカー片３２に先端部４ａで接続されたボルト４が、基端部４ｂが面材１の表面１３から外方に突出した状態で開口部１１に挿通されている。
【００４９】
このボルト４が挿通された調整スペーサ５０及びスペーサ部５は、開口部１１部分に内嵌された状態で配置され、基端部４ｂには手摺用ブラケット８の固定部８１に挿通されるとともに、固定部８１よりも基端側にナット６が締結されている。
また、第１アンカー片３１、第２アンカー片３２、調整スペーサ５０、スペーサ部５、固定部８１はそれぞれ軸方向で隣接した状態となっており、ナット６が締結されていることで、ブラケット８は、ボルト４を介して、アンカー部３を構成する第１アンカー片３１及び第２アンカー片３２とで面材１を挟持した状態となっている。これにより手摺用ブラケット８はアンカー部３で支持力を得て面材１に固定されている。
【００５０】
次に、物品固定具２により手摺用ブラケット８を面材１に固定する方法について説明する。
なお、手摺用ブラケット８が取り付けられる面材１は、例えば、リフォームにおいて、手摺が後付けで取り付けられる階段の中空の側壁の壁面を構成するものが挙げられる。この階段の側壁は、例えば、壁パネルの一方の表面に石膏ボード１６が貼着されることで構築され、手摺用ブラケット８が取り付けられる部位には、下地材が配置されていない。
【００５１】
まず、図６（ａ）に示すように、面材１において、壁下地材が無い箇所（壁パネルよりなる壁の場合、桟材、框材を避けた箇所）、手摺用ブラケット８が取り付けられるべき部分に、表面側からホルソーなどを用いて、面材１に対して略垂直に穿孔し、面材１の表裏面１３，１７を貫通する開口部１１を形成する。開口部１１は、アンカー部３が挿入可能な程度の小径のものであり、例えば、第１及び第２アンカー片３１，３２が厚み約４ｍｍ、全長約９０ｍｍ、幅約１８ｍｍとし、ボルト４の径を約６φ等とした場合に内径約２５ｍｍとする。なお、この場合第２アンカー片３２のネジ孔３２ｃの径は６．４φとし、図４に示す長さＬは０．５ｍｍとする。
【００５２】
一方、図６（ｂ）に示すように、物品固定具２では、ボルト４が挿通された第２アンカー片３２を、ボルト４上にて先端部４ａの第１アンカー片３１に隣接して重ねた状態で配置させ、調整スペーサ５０、スペーサ部５を基端部４ｂ側に配置させて、基端にナット６を螺合した状態とする。なお、第２アンカー片３２の当接面３２１には、粘着テープを貼設してもよい。このように当接面３２１に粘着テープを貼設しておけば、アンカー部３を面材１の裏面側に配置した際に、ボルト４を表面側に引くことで、裏面１７における開口部１１の周縁部分に粘着テープを介して第２アンカー片３２を取り付けることができる。
【００５３】
そして、図７に示すように、物品固定具２の互いに重ねた第１アンカー片３１及び第２アンカー片３２のそれぞれの先端部３１ｂ，３２ｂを、面材１の表面側から開口部１１に挿入する。このとき、第１アンカー片３１及び第２アンカー片３２とをそれらの先端部３１ｂ，３２ｂから挿入していき基端部３１ａ，３２ａ近傍まで挿入した後、第１アンカー片３１及び第２アンカー片３２を、ボルト４が開口部１１の開口方向に対して平行となるように挿入する。この物品固定具２は側面視略Ｌ字状となっているので、開口部１１への挿入の際には、開口部１１とほぼ平行方向に差し込む（矢印Ｍで示す）動作と、第１アンカー片３１及び第２アンカー片３２が接続されたボルト４の先端部４ａを挿入する際の押し込みながらの一方向の回転（矢印Ｎで示す）動作だけで容易に挿入することができる。
【００５４】
そして、図８に示すように、第１アンカー片３１及び第２アンカー片３２からなるアンカー部３を面材１の裏面側に完全に位置させる。そして、開口部１１の略中心をボルト４が挿通した状態とする。このとき、第２アンカー片３２では、先端部３２ｂとともに、基端部の延出部３４が、ボルト４を挟んで先端部３２ｂと反対側の面材１の裏面１７部分、つまり、面材１の裏面側の開口縁部分で当接可能となる。これにより、面材１の裏面側に配置されたアンカー部４は表面側に抜けにくくなっている。
次いで、図９に示すように、調整スペーサ５０及びスペーサ部５を開口部１１に挿入して、該開口部１１内に配置し、当該開口部１１を閉塞する。このとき、スペーサ部５はボルト４に螺合した状態で外嵌していることから、周方向に回転させることでボルト４の先端部４ａ方向に移動させる。そして、この回転移動によりフランジ部５４を開口部１１の表面側の縁部に当接させることで、調整スペーサ５０及びスペーサ部５により開口部１１は閉塞された状態となり、物品固定具２の仮止めが行われる。なお、調整スペーサ５０は、スペーサ部５の移動によりボルト４の先端部４ａ側に押されて移動する。また、このスペーサ部５を面材１の表面側から裏面側に移動させる作業は、特殊スパナ４４を用いて行ってもよい。すなわち、面材１の表面側において、ナット６を外して、スペーサ部５が取り付けられたボルト４に、特殊スパナ４４（図５（ｄ）参照）の挿通孔４４ｅを挿通させ、突出棒４４ａ，４４ａをスペーサ部５の底板部５ｃの穴５６，５６に挿入して、特殊スパナ４４をボルト４の軸を中心に回動させることでスペーサ部５を裏面側に移動させていく。
【００５５】
また、このスペーサ部５を開口部１１に挿入する作業の際には、面材１の裏面１７側で第２アンカー片３２の先端部３２ｂと、基端部３２ｂ側の延出部３４とを面材１の裏面１７に当接させることができるので、ボルト４を表面側に引きながら行うことで、ボルト４を、上下左右の位置を決めることができ、スペーサ部５を開口部１１に挿入する作業を安定した状態で容易に行うことができる。さらに、スペーサ部５を表面側に移動させて、フランジ部５４を面材１の表面側の開口縁部に当接させる。なお、フランジ部５１が表面１３側の開口縁部に当接しない場合は、スペーサ部５を特殊スパナ４４を用いて、さらに裏面側に移動させて、の先端を第２アンカー片３２の基端部３２ａに当接させ、縮小部５１を潰すことで当接させてもよい。これにより、第２アンカー片３２の先端部３２ｂ及び延出部３４と、フランジ部５４とで面材１を表裏側からそれぞれ挟んだ状態となり、物品固定具２は、第１及び第２アンカー片３１，３２とが重なり合った状態でも面材１に安定した状態で仮固定される。
【００５６】
次いで、面材１の表面側において、ナット６を回転させて、ボルト４の基端部４ｂを作業者が指でつかめる位置まで、ボルト４の先端部４ａ側に移動させ、ボルト４の基端部４ｂに回転操作部Ｋを形成する（図１０参照）。
この回転操作部Ｋを介してボルト４を表面側から回転させることで第１アンカー片３１を所定の角度、ここでは１８０°回転させて、アンカー部３を開き（図１１参照）、第１アンカー片３１の切欠部３５と第２アンカー片３２の係合突起３６とが係合するように、ボルト４を手前側、つまり表面側に引っ張ることで、切欠部３５及び係合突起３６とを係合させる。
【００５７】
なお、ボルト４を回転操作することで第１アンカー片３１及び第２アンカー片３２とを所定角度に開かせる際に、ボルト４を軽く手前側に引いたり、戻したりしながら行うことで切欠部３５と係合突起３６とを係合させることが好ましい。つまり、ボルト４を所定角度回転させた後で、手前側にボルト４を引くことで、ボルト４自体が手前側に移動しない場合は、面材１の裏面側では係合突起３６が第１アンカー片３１の基端部３１ａの裏面に当接している状態であるので、まだ、完全に開いていないことが確認できる。ボルト４自体が手前側に移動した場合は、係合突起３６が第１アンカー片３１の切欠部３５に係合した状態であることが確認できる。さらに、完全に第１アンカー片３１及び第２アンカー片３２が１８０度開いている状態であるかどうかの確認は、更にボルト４を回転させることで確認できる。また、このボルト４の回転操作中では、第２アンカー片３２の先端部３２ｂ及び延出部３４と、フランジ部５４とで、第２アンカー片３２及びスペーサ部５は仮止めされた状態となっており、ボルト４を回転させることで一体的に回転する第１アンカー片３１の回転動作を容易に安定して行うことができるものとなっている。これにより、アンカー部３における第１アンカー片３１及び第２アンカー片３２の相対的な回転動作を容易に行うことができる。
【００５８】
ここで、切欠部３５に係合突起３６が係合していない場合は、ボルト４によって回動するのは第１アンカー片３１のみであるが、両者が係合している状態であるときは、ボルト４の回転により第１アンカー片３１が回転すると共に、係合突起３６が切欠部３５に係合した第２アンカー片３２も回転する。つまり、切欠部３５と係合突起３６との係合状態によりボルト４による第１アンカー片３１の単独回転は抑止され、アンカー部３が開いた状態が保持されるので、その状態でボルト４を回転させようとすると、第１アンカー片３１を回動させる力に加えて、第２アンカー片３２を回動させる力を加える必要が生じる。
これにより、作業者はボルト４を回転させる際に、回転させる際に感じる重さにより、面材１の裏面１７側で、アンカー部３が開いている状態であることを面材１の表面１３側から確認することができる。
図１０では切欠部３５と係合突起３６とが係合した状態を示している。このとき、第１アンカー片３１の当接面３１１及び第２アンカー片３２の当接面３２１はそれぞれ略同一平面上に配置されるとともに、それぞれ面材１の裏面１７に面接触の状態で当接される。
【００５９】
次いで、ナット６をスペーサ部５に接するまで回転移動させた後、図１２に示すように、ボルト４を手前側（面材の表面側）に引っ張り続けた状態で、特殊スパナ４４を用いてスペーサ部５を回し、さらに、スパナによりナット６を回し、面材１から手前側に突出するボルト４が所定の長さ（出寸法）になるまで締め付ける。
次いで、図１３に示すように、特殊スパナ４４やナット６をボルト４から外した後、面材１の表面１３から突出したボルト４部分に基端部４ｂから手摺用ブラケット８の固定部８１に形成された貫通孔８２を挿通させて、固定部８１が挿通されたボルト４に、先に外したナット６を再び螺合し、締め付ける。
【００６０】
このナット６の締め付けにより、ボルト４が連結している第１アンカー片３１及び第２アンカー片３２と、固定部８１とに面材１が挟まれた状態となり、スペーサ部５には軸方向にアンカー部３への押圧がかかるとともに、アンカー部３を構成する第１アンカー片３１及び第２アンカー片３２のそれぞれの基端部３１ａ，３２ａが、ボルト４を介して、ボルト４の基端部側に引っ張られた状態、つまり基端部３１ａ，３２ａがボルト４を介して面材側に引っ張られた状態となる。これらの作用により、縮小部５１は軸方向から上下面に外圧がかかることとなり軸方向にさらに潰れ、スペーサ部５自体の軸方向の長さが縮小し、第１アンカー片３１及び第２アンカー片３２と固定部８１とが面材１を強固に挟持した状態となり、よって、固定部８１は面材１の表面１３に押しつけられた状態で固定される。
【００６１】
また、ナット６を締め付けることで、第１アンカー片３１及び第２アンカー片３２では、面材１の裏面１７に当接されたそれぞれの先端部３１ｂ，３２ｂの当接面３１１，３２１は、それぞれ基端部３１ａ，３２ａの裏面より面材１の裏面側に位置していることから、全面的に面材１の裏面１７を押圧し、全面的に裏面１７に当接されたものとなる。よって、アンカー部３は確実に面材１の裏面に固着された状態となる。
さらに、固定部８１の固定面８１ａに形成された座掘部８５内に面材１の表面１３から若干突出するフランジ部５４が配置されることとなり、固定部８１の固定面８１ａは面材１の表面１３に確実に当接した状態となる。
【００６２】

TECHNICAL FIELD OF THE INVENTION
The present invention relates to an article fixing device for attaching an article such as a handrail to a wall surface, an article fixing structure, and an article fixing method.
[0002]
[Background technology]
Conventionally, when an article such as a handrail is fixed to a wall component constituting a wall surface, the wall component must have a strength capable of supporting an article to be fixed, but the wall component is provided between pillars. If the material is solid and relatively brittle, such as gypsum board pasted on plywood, fix and support the product directly from the surface on which the product of the wall component is attached, that is, from the front side with mounting screws etc. Can not. For this reason, an opening is formed through the wall component to penetrate the wall component, the anchor is inserted through the opening, and the anchor is brought into close contact with the back side of the wall component such as a gypsum board. The article is supported by the anchor portion in this state. The opening formed in the wall component at this time is for allowing the anchor part to be inserted from the front side and connecting the anchor part and the part to which the article is attached by being disposed on the front side. It is desirable that the diameter be as small as possible.
[0003]
Examples of the article fixing device using the anchor portion inserted into the small-diameter opening as described above include, for example, two substantially same-shaped first anchor pieces in which the anchor portion inserted from the opening is curved in the lateral direction. The second anchor piece is fixed to the base end of the first anchor piece so as to be orthogonal to the base end of the first anchor piece, and the distal end of the mounting bolt inserted into the opening is fixed to the first anchor piece. A rotatable fitting of the base member of the mounting bolt, and a surface-side member that cannot be inserted through the opening at a position closer to the base end of the mounting bolt than the first and second anchor pieces. Some lock nuts are screwed together so that they do not come off from the side.
[0004]
In this article fixing device, the first anchor piece is also rotated by rotating the mounting bolt about the axis, and the first anchor piece is rotatable relative to the second anchor piece. The piece and the second anchor piece are inserted into the opening from the distal end side in a state where they overlap each other.
Therefore, when attaching the article fixing device to the wall component, first, the first and second anchor pieces are inserted into the rear surface side of the wall component from the opening and placed in a folded state. Then, the first anchor piece is turned by rotating the mounting bolt from the front side, the first and second anchor pieces are opened, and the first and second anchor pieces and the opening are tightened by tightening the lock nut. It is attached by sandwiching a wall component with an uninsertable front side member (for example, see Patent Document 1).
[0005]
[Patent Document 1]
JP-A-2002-70818
[0006]
[Problems to be solved by the invention]
By the way, in the configuration of Patent Document 1, when attaching the article fixture to the wall surface component, the first and second anchor pieces are arranged on the back surface side of the wall surface component, and then the mounting bolt is turned on the front surface side. When the first anchor piece is rotated to open the first anchor piece and the second anchor piece, the rotation of the mounting bolts on the front surface side actually requires both anchors on the back surface side of the wall component. It is not possible to confirm whether the piece is properly opened at an angle of, for example, 180 °, and the angle is to be opened (180 °) by intuitively rotating the rear surface of the wall component.
For this reason, the first anchor piece is rotated by a predetermined angle by operating the mounting bolt, and the first anchor piece is intended to be rotated by a predetermined angle of 180 ° with respect to the second anchor piece. Then, the second anchor piece rotates with the rotation of the first anchor piece, and a state where the second anchor piece does not open at the intended predetermined angle of 180 ° or a state where it opens at the predetermined angle of 180 ° or more occurs.
In this state, when the lock nut is tightened and the wall surface component is sandwiched between the wall member and the surface member, when the article is attached to the base end portion of the bolt on the surface side of the wall member, the anchor piece is used. The product cannot be reliably supported.
[0007]
Also, when fixing to the wall surface component, the first and second anchor pieces are overlapped and inserted deeply into the opening along the bending direction so as to be screwed in, and the base end portion is orthogonal to the bending direction. Since the bolts are inserted so as to protrude in the axial direction of the mounting bolts, it takes time to mount the bolts.
The object of the present invention is to be able to be easily attached to a face material constituting a wall surface component without any trouble and to be inserted from an opening provided in the face material and to be arranged on the back side of the face material. This is to fix the article to the face material via the anchor portion so as to securely support the article.
[0008]
[Means for Solving the Problems]
In order to solve the above problems, the invention described in claim 1 is, for example, as shown in FIGS.
An anchor portion 3 inserted through an opening 11 formed in a face material (for example, face material 1 made of plywood 15, gypsum board 16, etc.) and arranged on the back surface 17 side of the face material 1; A bolt 4 inserted into the opening 11 and a spacer 5 into which the bolt 4 is inserted and inserted into the opening 11 to close the opening 11. An article (for example, a handrail bracket 8) is attached to the surface 13 side of the face material 1 so that the article 8 and the anchor portion 3 sandwich the face material 1 via the bolt 4 so that the article 8 In the article fixing device 2 for fixing the
The anchor portions 3 are inserted from the distal end portions (31b, 32b) side to the back surface 17 side of the face material 1 from the opening portions 11 in a state where they overlap with each other, and the respective base end portions 31a, 32a are connected to the bolts. 4, two blades (e.g., the first and second blades) that can be relatively rotated and opened by rotating the bolt 4 about an axis, and each of the tip portions can abut against the back surface 17 of the face material 1. 1) and a second anchor piece 32).
The two blades 31 and 32 are each formed of a long linear flat plate member having a width that can be inserted into the opening 11, and the two blades 31 and 32 have the same shape. The bolts 4 are engaged with each other by pulling the bolt 4 toward the surface 13 in a state where the two blades 31 and 32 are opened at a predetermined angle (for example, 180 °), and the relative positions of the two blades 31 and 32 are compared. An engagement portion (for example, the engagement protrusion 36) and an engaged portion (for example, the notch portion 35) for suppressing the excessive rotation are formed,
The spacer portion 5 is screwed to the bolt 4 so as to be movable in the axial direction of the bolt 4, and when the spacer portion 5 is inserted into the opening portion 11, the spacer portion 5 engages with the front edge of the opening portion 11. It is characterized by having a flange portion 54 to be stopped.
[0009]
According to the first aspect of the present invention, the anchor portion 3 connected to the bolt 4 inserted into the opening 11 and disposed on the back surface 17 side of the face material 1 has the two blades 31, 32, the two blades 31 and 32 are inserted into the back surface 17 side of the face material 1 from the opening 11 from the front end (31b, 32b) side in a state where the two blades 31 and 32 overlap each other. By rotating the bolt 4 inserted through the portion 11 around the axis on the front side, the bolt is relatively rotated and opened by a predetermined angle, the bolt 4 is pulled toward the front surface 13, and the two blades 31, A state in which the relative rotation between the two blade portions 31 and 32 is suppressed by engaging the engaging portion 36 and the engaged portion 35 formed respectively with each other, that is, With the blades 31 and 32 kept open It can be contacted to the surface material 1 of the back 17 in a state. In other words, if the bolt 4 cannot be pulled when the bolt 4 is rotated to some extent and pulled even when the bolt 4 is rotated from the front surface 13 side, the engaging portion 36 and the engaged portion 35 are engaged. In the case where the two blades 31 and 32 are closed, it can be determined that they are engaged with each other. It is possible to confirm that the operation of opening the two blades at a predetermined angle on the back surface side can be easily performed.
[0010]
By attaching the article 8 to the bolt 4 on the front surface 13 side of the face material 1 in a state in which the two blades 31 and 32 are held open at a predetermined angle in this manner, The face material 1 can be firmly held between the two blades 31 and 32 opened at a predetermined angle, and the article 8 can be securely fixed to the face material 1 without fail. Therefore, it can be easily attached to the surface material constituting the wall surface component and the like without any trouble, and the anchor portion inserted from the opening provided in the surface material and arranged on the back surface side of the surface material is provided. The article can be fixed to the face material so as to securely support the article.
[0011]
Further, since the two blades 31 and 32 are each formed of a long linear flat plate member having a width that can be inserted into the opening 11, the two blades 31 and 32 are overlapped. The front material 1 can be easily inserted into the opening 11 of the front material 1 from the front end portions 31b and 32b, and when the front material 1 is opened on the rear surface 17 side, the front material is brought into contact with the front material by face contact. 1 can be brought into contact with the back surface 17, and when the face material 1 is sandwiched between the face material 1 and the article 8 attached to the bolt via the bolt, the supporting force for supporting the article 8 is increased from the face material 1. Can be obtained reliably.
[0012]
Further, the bolt 4 is provided with a spacer portion 5 which is inserted through the opening portion 11 and is interposed between the anchor portion 3 and the article 8 to be attached. The opening 11 of the face material 1 sandwiched between the part 3 and the article 8 can be closed.
[0013]
In addition, since the spacer portion 5 is formed with a flange portion which is locked to the front edge of the opening portion 11 when inserted into the opening portion 11, the two blades After the anchor portion 3 having the portion is disposed on the back surface 17 side of the face material 1 via the opening 11, the two blade portions 31, 32 are opened at a predetermined angle via the bolt, and the face material is opened. By pressing the spacer portion 5 toward the face material 1 and inserting the spacer portion 5 into the opening 11 in a state where the opening 11 is brought into contact with the back surface of the opening 1, the opening 11 can be almost completely closed. Further, since the spacer portion 5 is screwed to the bolt 4 so as to be movable in the axial direction of the bolt 4, the anchor portion 3 including the two blade portions is connected to the surface through the opening portion 11. After being arranged on the back surface 17 side of the material 1, the two blade portions 31, 32 are opened through a predetermined angle via the bolts, and the spacer portion 5 is brought into contact with the back surface of the face material 1. By moving the flange 54 to the edge of the opening 11 on the front surface side by moving it to the face material 1 side, the article fixing tool 2 can be temporarily fixed to the face material 1. Thereby, the work when attaching the article 8 to the bolt 4 on the front surface side can be easily performed.

The fixing portion 81 has a fixing surface 81 a that completely covers the opening 11 and covers the surface material surface 13 around the opening 11, and the fixing surface 81 a communicates with the through hole 82. In addition, the fixing surface 81a communicates with the through hole 82, and when contacting the surface material 1, the flange portion 54 of the spacer portion 5 inserted into the opening 11 of the surface material 1 is internally fitted. A portion 85 is formed.
[0048]
The bracket 8 configured as described above is fixed to the face material 1 by the article fixture 2. That is, as shown in FIG. 1, the first anchor piece 31 and the second anchor piece 32 arranged on the back side of the face material 1 are arranged so as to extend vertically from the base ends 31a and 32a, respectively. Contact surfaces 311 and 321 are in contact with the back surface 17 of the plywood 15 above and below the opening 11. The bolt 4 connected to the first anchor piece 31 and the second anchor piece 32 at the distal end 4 a is inserted into the opening 11 with the base end 4 b protruding outward from the surface 13 of the face material 1. Have been.
[0049]
The adjustment spacer 50 and the spacer portion 5 into which the bolts 4 are inserted are disposed in a state of being fitted inside the opening portion 11, and the base end portion 4b is inserted through the fixing portion 81 of the handrail bracket 8, and The nut 6 is fastened to the base end side of the fixing portion 81.
Further, the first anchor piece 31, the second anchor piece 32, the adjustment spacer 50, the spacer section 5, and the fixing section 81 are adjacent to each other in the axial direction, and the nut 6 is fastened, so that the bracket 8 Is a state in which the face material 1 is sandwiched between the first anchor piece 31 and the second anchor piece 32 constituting the anchor part 3 via the bolt 4. As a result, the handrail bracket 8 is fixed to the face material 1 by obtaining the supporting force at the anchor portion 3.
[0050]
Next, a method of fixing the handrail bracket 8 to the face material 1 using the article fixing tool 2 will be described.
The face material 1 to which the handrail bracket 8 is attached may be, for example, one that forms a wall surface of a hollow side wall of a staircase to which a handrail is attached later in a reform. The side wall of this staircase is constructed by, for example, attaching a gypsum board 16 to one surface of a wall panel, and no base material is disposed at a portion where the handrail bracket 8 is attached.
[0051]
First, as shown in FIG. 6 (a), in the face material 1, a place where there is no wall base material (in the case of a wall made of a wall panel, a place where the bar material and the frame material are avoided) and the handrail bracket 8 are attached. An opening 11 penetrating through the front and back surfaces 13 and 17 of the face material 1 is formed in a portion to be formed by using a forcer or the like from the front surface side and substantially perpendicularly to the face material 1. The opening 11 has a small diameter such that the anchor 3 can be inserted. For example, the first and second anchor pieces 31 and 32 have a thickness of about 4 mm, a total length of about 90 mm, and a width of about 18 mm. Is about 25 mm. In this case, the diameter of the screw hole 32c of the second anchor piece 32 is 6.4φ, and the length L shown in FIG. 4 is 0.5 mm.
[0052]
On the other hand, as shown in FIG. 6B, in the article fixing device 2, the second anchor piece 32 into which the bolt 4 has been inserted is overlapped on the bolt 4 adjacent to the first anchor piece 31 of the distal end 4 a. The adjustment spacer 50 and the spacer portion 5 are arranged on the base end portion 4b side, and the nut 6 is screwed to the base end. Note that an adhesive tape may be attached to the contact surface 321 of the second anchor piece 32. If the adhesive tape is stuck on the contact surface 321 in this manner, when the anchor portion 3 is arranged on the back surface side of the face material 1, the bolt 4 is pulled toward the front surface side, so that the opening 11 on the back surface 17 is formed. The second anchor piece 32 can be attached to the peripheral portion of the base member via an adhesive tape.
[0053]
Then, as shown in FIG. 7, the respective distal end portions 31 b, 32 b of the first anchor piece 31 and the second anchor piece 32 of the article fixing device 2, which are overlapped with each other, are inserted into the opening 11 from the front side of the face material 1. I do. At this time, the first anchor piece 31 and the second anchor piece 32 are inserted from the distal end portions 31b and 32b of the first anchor piece 31 and the second anchor piece 32 to the vicinity of the base end portions 31a and 32a. 32 is inserted so that the bolt 4 is parallel to the opening direction of the opening 11. Since the article fixture 2 is substantially L-shaped when viewed from the side, when the article fixture 2 is inserted into the opening 11, it is inserted in a direction substantially parallel to the opening 11 (indicated by an arrow M), and the first anchor When inserting the tip 4a of the bolt 4 to which the piece 31 and the second anchor piece 32 are connected, the bolt 4 can be easily inserted only by pushing in one direction while rotating (indicated by an arrow N).
[0054]
Then, as shown in FIG. 8, the anchor portion 3 including the first anchor piece 31 and the second anchor piece 32 is completely located on the back surface side of the face material 1. Then, the bolt 4 is inserted into the substantially center of the opening 11. At this time, in the second anchor piece 32, together with the distal end portion 32 b, the extension portion 34 at the base end portion has the back surface 17 portion of the surface material 1 opposite to the distal end portion 32 b across the bolt 4, that is, the surface material 1 Can be brought into contact at the opening edge portion on the back surface side. This makes it difficult for the anchor portion 4 disposed on the back surface side of the face material 1 to come off to the front surface side.
Next, as shown in FIG. 9, the adjustment spacer 50 and the spacer unit 5 are inserted into the opening 11, are arranged in the opening 11, and the opening 11 is closed. At this time, since the spacer portion 5 is externally fitted while being screwed to the bolt 4, the spacer portion 5 is moved in the direction of the tip 4 a of the bolt 4 by rotating in the circumferential direction. Then, the flange 11 is brought into contact with the edge of the opening 11 on the surface side by this rotational movement, so that the opening 11 is closed by the adjustment spacer 50 and the spacer 5, and the provisional fixing of the article fixture 2 is performed. A stop is made. The adjustment spacer 50 is moved by being pushed by the distal end 4 a of the bolt 4 by the movement of the spacer portion 5. The operation of moving the spacer portion 5 from the front surface side of the face material 1 to the rear surface side may be performed by using a special spanner 44. That is, on the front side of the face material 1, the nut 6 is removed, and the insertion hole 44e of the special wrench 44 (see FIG. 5D) is inserted into the bolt 4 to which the spacer portion 5 is attached. 44a is inserted into the holes 56 of the bottom plate portion 5c of the spacer portion 5, and the spacer portion 5 is moved to the back side by rotating the special spanner 44 about the axis of the bolt 4.
[0055]
When the spacer 5 is inserted into the opening 11, the distal end portion 32 b of the second anchor piece 32 and the extending portion 34 on the base end portion 32 b are located on the back surface 17 of the face material 1. Since the bolts 4 can be brought into contact with the back surface 17 of the face material 1, the bolts 4 can be pulled up to the front surface side, so that the bolts 4 can be positioned up, down, left, and right, and the spacer 5 is inserted into the opening 11. Can be easily performed in a stable state. Further, the spacer portion 5 is moved to the front surface side, and the flange portion 54 is brought into contact with the opening edge portion on the front surface side of the face material 1. When the flange portion 51 does not contact the opening edge on the front surface 13 side, the spacer portion 5 is further moved to the rear surface side using the special spanner 44 so that the distal end of the spacer portion 5 is the proximal end of the second anchor piece 32. The contact may be made by abutting the portion 32a and crushing the reduction portion 51. As a result, the surface material 1 is sandwiched between the front and back sides of the distal end portion 32b and the extending portion 34 of the second anchor piece 32 and the flange portion 54, and the article fixing device 2 becomes the first and second anchor pieces. Even when the parts 31 and 32 overlap, they are temporarily fixed to the face material 1 in a stable state.
[0056]
Next, on the front side of the face material 1, the nut 6 is rotated to move the proximal end 4 b of the bolt 4 toward the distal end 4 a of the bolt 4 until the operator can grasp the base 4 b with a finger. The rotation operation part K is formed in the part 4b (see FIG. 10).
By rotating the bolt 4 from the front side through the rotating operation part K, the first anchor piece 31 is rotated by a predetermined angle, here 180 °, to open the anchor part 3 (see FIG. 11), and The notch 35 and the engagement protrusion 36 are engaged by pulling the bolt 4 toward the front side, that is, the front surface side so that the notch 35 of the piece 31 and the engagement protrusion 36 of the second anchor piece 32 are engaged. Combine.
[0057]
When the first anchor piece 31 and the second anchor piece 32 are opened at a predetermined angle by rotating the bolt 4, the notch is formed by lightly pulling or returning the bolt 4 to the near side. It is preferable that the engagement protrusion 35 is engaged with the engagement protrusion 36. In other words, if the bolt 4 itself is not moved to the front side by pulling the bolt 4 to the front side after rotating the bolt 4 by the predetermined angle, the engagement projection 36 is attached to the first anchor on the back side of the face material 1. Since the piece 31 is in contact with the back surface of the base end 31a of the piece 31, it can be confirmed that the piece 31 has not been completely opened yet. When the bolt 4 itself moves to the near side, it can be confirmed that the engagement protrusion 36 is in a state of being engaged with the notch 35 of the first anchor piece 31. Further, whether the first anchor piece 31 and the second anchor piece 32 are completely opened by 180 degrees can be confirmed by further rotating the bolt 4. Further, during the rotation operation of the bolt 4, the second anchor piece 32 and the spacer portion 5 are temporarily fixed by the distal end portion 32 b and the extending portion 34 of the second anchor piece 32 and the flange portion 54. By rotating the bolt 4, the rotation operation of the first anchor piece 31 which rotates integrally can be easily and stably performed. Thereby, the relative rotation operation of the first anchor piece 31 and the second anchor piece 32 in the anchor portion 3 can be easily performed.
[0058]
Here, when the engagement protrusion 36 is not engaged with the notch 35, only the first anchor piece 31 is rotated by the bolt 4, but when both are engaged, The rotation of the bolt 4 causes the first anchor piece 31 to rotate, and the second anchor piece 32 in which the engagement protrusion 36 is engaged with the notch 35 also rotates. That is, the independent rotation of the first anchor piece 31 by the bolt 4 is suppressed by the engagement state of the notch 35 and the engagement projection 36, and the state where the anchor part 3 is opened is maintained. If it is attempted to rotate, it is necessary to apply a force for rotating the second anchor piece 32 in addition to a force for rotating the first anchor piece 31.
Thus, when the operator rotates the bolt 4, the operator feels that the anchor portion 3 is open on the back surface 17 side of the surface material 1 due to the weight felt when rotating the bolt 4. You can check from the side.
FIG. 10 shows a state in which the notch 35 and the engagement protrusion 36 are engaged. At this time, the contact surface 311 of the first anchor piece 31 and the contact surface 321 of the second anchor piece 32 are respectively arranged on substantially the same plane, and are respectively in contact with the back surface 17 of the face material 1 in surface contact. Touched.
[0059]
Next, after rotating the nut 6 until it comes into contact with the spacer portion 5, as shown in FIG. 12, the bolt 4 is continuously pulled toward the front side (the surface side of the face material), and the spacer 4 is used with the special spanner 44. The part 5 is turned, and the nut 6 is further turned with a spanner, and tightened until the bolt 4 protruding forward from the face material 1 reaches a predetermined length (extended dimension).
Next, as shown in FIG. 13, after the special spanner 44 and the nut 6 are removed from the bolt 4, the bolt 4 protruding from the surface 13 of the face material 1 is attached to the fixing portion 81 of the handrail bracket 8 from the base end 4 b. The nut 6 removed earlier is screwed again to the bolt 4 into which the fixing part 81 is inserted by inserting the formed through hole 82 and tightened.
[0060]
By tightening the nut 6, the face material 1 is sandwiched between the first anchor piece 31 and the second anchor piece 32 to which the bolt 4 is connected and the fixing portion 81, and the spacer portion 5 is While the anchor portion 3 is pressed, the base end portions 31a and 32a of the first anchor piece 31 and the second anchor piece 32 that constitute the anchor portion 3 are connected to the base end portion of the bolt 4 via the bolt 4. Side, that is, the base ends 31a and 32a are pulled toward the face material via the bolt 4. Due to these actions, the reducing portion 51 is subjected to external pressure from the axial direction to the upper and lower surfaces, and further collapses in the axial direction, the axial length of the spacer portion 5 itself is reduced, and the first anchor piece 31 and the second anchor piece 32 and the fixing portion 81 firmly sandwich the face material 1, so that the fixing portion 81 is fixed while being pressed against the surface 13 of the face material 1.
[0061]
Further, by tightening the nut 6, in the first anchor piece 31 and the second anchor piece 32, the contact surfaces 311, 321 of the respective distal end portions 31 b, 32 b abutted on the back surface 17 of the face material 1 respectively become Since it is located on the back surface side of the face material 1 from the back surfaces of the base end portions 31a and 32a, the back surface 17 of the face material 1 is entirely pressed, and the back surface 17 is entirely in contact with the back surface 17. Therefore, the anchor portion 3 is securely fixed to the back surface of the face material 1.
