Description

【０００１】
【発明の属する技術分野】
本発明は、壁面構成部材の表面に手摺り等の物品を取付けるための物品取付具に関するものである。
【０００２】
【従来の技術】
壁面構成部材の表面に手摺り等の物品を取付ける場合、壁面構成部材が例えば石膏ボードのように脆いものであると、壁面構成部材取付の表面側（物品が位置される側の面）から取付ねじ等によって物品の取付を行ったのでは、物品からの大きな荷重を支承することが不可能となり、採用できないものとなる。このため、壁面構成部材に開口部を形成して、アンカ片をこの開口部より挿通させて壁面構成部材の裏面側に配置して、壁面構成部材の裏面側に密着された状態のアンカ片によって物品からの荷重を支承させることが行われる。
【０００３】
従来、開口部に挿通されるアンカ片を利用した物品取付具としては種々のものが提案されているが、壁面構成部材の表面側に配設される保持部材とアンカ片とを、壁面構成部材の開口部を挿通される取付ボルトを介して連結することにより、アンカ片と保持部材とで壁面構成部材を挟持するようにしたものがある。そして、取付ボルトを有するものの中には、アンカ片にあらかじめ取付ボルトの一端部が連結されて、取付ボルトの基端部を把持しつつアンカ片が壁面構成部材の開口部よりその裏面側へと挿通させる作業を行うようにしたものもある（特開２０００−１４５０８９号公報参照）。
【０００４】
【発明が解決しようとする課題】
ところで、アンカ片による物品からの荷重の支承は、もっぱらアンカ片が壁面構成部材の裏面側に圧接されることに受け持たれるようになっている。例えば、アンカ片を壁面構成部材の開口部から上方へ伸びるように配置した場合、壁面構成部材の表面側に配置されて取付ボルトに連結される物品としての例えば手摺りに対して下方への荷重が作用したときは、アンカ片が壁面構成部材の裏面側に圧接されることになり、荷重支承が効果的に行われることになる。この一方、アンカ片が上記のように開口部から上方へ伸びた状態において、手摺りに上方への荷重が作用した場合は、開口部から上方へ伸びるアンカ片には壁面構成部材の裏面側から剥離されるような力を受けるので、この下方への荷重支承を効果的に行うことができないものとなる。
【０００５】
このような問題を解消するために、物品に作用する荷重の作用方向というものをあらかじめ想定して、物品への荷重作用方向とは反対方向にアンカ片が伸びるように位置設定される。また、アンカ片を壁面構成部材の開口部を境にして例えば上下の両方向に伸びるように設定して、物品に対して作用する上方向および下方向の両方の荷重に対しても対応できるようにすることも行われている。
【０００６】
しかしながら、壁面構成部材の裏面側に配置されるアンカ片を利用した荷重支承は、もっぱらアンカ片の壁面構成部材の裏面側への圧接を利用した荷重支承であり、壁面構成部材の裏面側から剥離される方向の荷重支承ということは期待されていなかったのが実状である。
【０００７】
本発明は以上のような事情を勘案してなされたもので、その目的は、取付ボルトを介して連結されるアンカ片と保持部材とで壁面構成部材を挟持するようにした場合に、アンカ片がより広い方向での荷重を支承できるようにした物品取付具およびその部品を提供することにある。
【０００８】
【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（請求項１に係る発明）にあってはその解決手法として次のようにしてある。すなわち、特許請求の範囲における請求項１に記載のように、
壁面構成部材に形成された開口部より挿通されて該壁面構成部材の裏面側に配置されるアンカ片と該壁面構成部材の表面側に配設される保持部材とを、該開口部を挿通される取付ボルトを介して連結することにより、該アンカ片と該保持部材とで該壁面構成部材を挟持するようにした物品取付具であって、
前記アンカ片として、第１アンカ片と第２アンカ片とが設けられ、
前記第１アンカ片の基端部に前記取付ボルトの先端部が一体回転するように連結され、
前記第２アンカ片の基端部が、前記第１アンカ片よりも前記取付ボルトの基端部側において、該取付ボルトに対して螺合されることなく回転自在に嵌合され、
前記第１アンカ片と前記第２アンカ片とが、その各先端部側に向けて伸びる所定面をもって、互いに重ならない相対回転姿勢時において、前記壁面構成部材の裏面側に当接可能となるように設定されていると共に、該第１アンカ片と該第２アンカ片とが互いに重なる相対回転姿勢時において、該第１アンカ片又は該第２アンカ片の一方が該第１アンカ片又は該第２アンカ片の他方に対して傾斜されて、該傾斜に基づき該第１アンカ片と該第２アンカ片とが離間するように設定され、
前記第１アンカ片の所定面に、前記壁面構成部材の裏面側に固着するための接着材が設けられていると共に、該接着材が、該第１アンカ片と該第２アンカ片とが互いに重なる相対回転姿勢時において、該第１アンカ片又は該第２アンカ片の一方が該第１アンカ片又は該第２アンカ片の他方に対して傾斜されることに基づき、該第２アンカ片に接触しないように設定されている、ようにしてある。上記解決手法を前提とした好ましい態様は、特許請求の範囲における請求項２以下に記載のとおりである。
【０００９】
【発明の効果】
請求項１に記載された発明によれば、アンカ片（少なくとも第１アンカ片）は、壁面構成部材の裏面側に圧接されるような荷重に対してのみならず、剥離されるような荷重、さらには壁面構成部材の裏面を摺動するような方向の荷重をも支承することができ、広い方向の荷重を支承することができる。また、接着材は、取付ボルトを利用した連結力でもってアンカ片と壁面構成部材の裏面側との間で強く押圧されるので、アンカ片と壁面構成部材の裏面側との接着による固着というものが常に確実に確保されて、上記の効果を確実に発揮させることができる。
また、第２アンカ片をその自重を利用して下方へ伸びる姿勢とする一方、第１アンカ片を取付ボルトの回転操作を利用して上方へ伸びる姿勢として、２つのアンカ片の伸び方向を大きく相違させて、より広い方向の荷重をしっかりと支承する上で好ましいものとなる。
さらに、第１アンカ片と第２アンカ片とが互いに重なる相対回転姿勢時において、該第１アンカ片又は該第２アンカ片の一方が該第１アンカ片又は該第２アンカ片の他方に対して傾斜されて、該第１アンカ片の所定面に設けられる接着材が該第２アンカ片に接触しないように設定されており、壁面構成部材の開口部に第１，第２アンカ片を挿入するに際して、第１アンカ片の所定面に設けられる接着材と第２アンカ片との接触防止を図ることができる。
【００１０】
請求項２に記載された発明によれば、第１，第２アンカ片は、壁面構成部材の裏面側に圧接されるような方向の荷重は勿論のこと、剥離される方向の荷重、さらには壁面構成部材の裏面に沿って摺動（回転方向）される方向の荷重をも支承することができ、広い方向に渡って荷重支承能力が大きなものとなる。
【００１１】
請求項３に記載された発明によれば、取り扱いの容易な両面接着テープを利用して、請求項１に対応した効果を得ることができる。
請求項４に記載された発明によれば、保持部材を、壁面構成部材を挟持するための挟持用部材と、取付ボルトに螺合されて所定の挟持力を得るための固定具となるロックナットとしての機能を兼用させることができる。
【００１２】
【発明の実施の形態】
本発明の第１実施形態を示す図１〜図１２において、物品取付具Ｍの構成要素についてまず説明すると、物品取付具Ｍは、第１アンカ片１と、第２アンカ片２と、取付ボルト３と、保持部材４とを有する。保持部材４は、後述するように、アンカ片と共働して壁面構成部材を挟持するための表面側部材とロックナットとを兼用したものとなっており、このような保持部材４は、施工時には、合成樹脂によって回転治具５とあらかじめ一体成形されている。この保持部材４と回転治具５との一体品を、以下の説明では、治具兼用部材ＪＫとして説明することとする。物品取付具Ｍは、実施形態ではさらに、金属製のワッシャ６とスペーサ７とを有する。
【００１３】
各アンカ片１と２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−以下同じ）によって、全体的に細長くかつ湾曲された形状とされている。すなわち、各アンカ片１、２は、全体的に一方向に湾曲された形状とされ、特にその先端部側においては曲がりの度合いが強くなっていて、横方向に大きく曲げられている。そして、取付ボルト３を中心として両アンカ片１と２とを相対回転させて互いに重ね合わせたとき、幅方向においては互いにはみ出ないように整合されるように形状設定されている（ほぼ合同形状に設定）。
【００１４】
第１アンカ片１の基端部には、特に図５に示すようにねじ孔１ａが形成され、このねじ孔１ａに取付ボルト３の先端部が螺合されている。そして、取付ボルト３の先端部に第１アンカ片１が螺合された状態において、取付ボルト３と第１アンカ片１とが仮固定されている。この仮固定は、第１アンカ片１と取付ボルト３とが一体回転するように、かつ所定以上の相対トルクが作用したときには固定解除されるように設定されている。このような仮固定を行うには、例えば、図５に示すかしめ（かしめ部分を符号ｋ１で示す）によって得ることができる。
【００１５】
第２アンカ片２は、取付ボルト３に対して、第１アンカ片１よりも取付ボルト３の基端部側において、第２アンカ片２の基端部（に形成された取付孔２ａ）が回転自在に嵌合されている。すなわち、第２アンカ片２は、取付ボルト３に対しては螺合されることなく自由に回転自在とされて、第１アンカ片１と取付ボルト３とに対してそれぞれ相対回転可能とされている。
【００１６】
各アンカ片１、２は、図３、図４に示すように、壁面構成部材Ｈに形成された開口部１１を通して壁面構成部材Ｈの裏面側に配設されるものであり、取付ボルト３を介して連結されたアンカ片１、２と保持部材４とで壁面構成部材Ｈを挟持して、アンカ片１、２の壁面構成部材Ｈへの取付完了状態となる。なお、この取付作業の点については後述する。
【００１７】
前記スペーサ７は、例えば合成樹脂により形成されて、壁面構成部材Ｈの厚さの相違つまり開口部１１の長さの相違に対応するもので、第２アンカ片２と保持部材４との間において、取付ボルト３に取付けられる。すなわち、壁面構成部材Ｈの厚さが厚いときにスペーサ７が用いられ、壁面構成部材Ｈの厚さが薄いときは使用されない。スペーサ７は、他の部材の取付状態にかかわらず取付ボルト３に対して取付、取外しを容易に行えるように、周方向に切欠部７ａが形成されて、この切欠部７ａを利用して取付ボルト３からの取外し、取付けが行われる。なお、切欠部７ａの開口幅は取付ボルト３の直径よりも幾分小さくされて、取付け、取外しの際は、弾性変形を利用して切欠部７ａの開口幅を広げることにより行われる。なお、ワッシャ６は、アンカ片２が直接スペーサ７あるいは保持部材４に当接するのを防止するためのものである。
【００１８】
取付ボルト３の基端部には、図１、図２に示すように、ドライバ等の回転工具が係合可能なように、径方向に伸びる溝部３ｄが形成されている。第１アンカ片１を１８０度回転させて配置させるには、溝部３ｄの回転位置や回転工具の回転位置によって目視して確認できる。
【００１９】
前記保持部材４と回転治具５との一体品である治具兼用部材ＪＫの詳細が、図６、図７に示される。保持部材４は、開口部１１内に挿通される筒部４ａと、筒部４ａに形成されて取付ボルト３が螺合されるねじ孔４ｂと、筒部４ａの一端部に形成されて開口部１１の直径よりも大きな外径を有する円環状のフランジ部４ｃとを有する。回転治具５は、筒状の本体部５ａを有して、本体部５ａの内孔が、取付ボルト３がスムーズに挿通可能な貫通孔５ｂとされている。そして、本体部５ａの外周には、周方向等間隔に、複数（実施形態では２個）の回転力付与用の突起部５ｃが形成されている。
【００２０】
保持部材４と回転治具５とは、連結部８によって連結されている。連結部８は、薄肉状とされて、所定以上のトルクを受けて破断される弱化部を構成している。このような治具兼用部材ＪＫは、合成樹脂による一体成形とされている（例えば射出成形）。連結部８を所定以上のトルクを受けて破断される弱化部として構成するには、連結部８を射出成形時にあらかじめ薄肉として形成する他、例えば、周方向において部分的に保持部材４と回転治具５とを連結されるように射出成形したり、射出成形後に連結部８の外周に機械加工によって溝部を形成して連結部８を薄肉にする等、適宜の手法が採択し得る。
【００２１】
再び図１、図２において、各アンカ片１、２のうち、壁面構成部材Ｈの裏面側に臨む側となる面には、あらかじめ両面接着テープ９が貼り付けられており、この両面接着テープ９が図１、図２中ハッチングを施して示される。両面接着テープ９は、回転抵抗力付与手段および剥離防止手段となるもので、施工前の状態では、両面接着テープ９の一方の接着面がアンカ片１、２の所定面（壁面構成部材Ｈの裏面側を向くこととなる面）にあらかじめ接着されており、他方の接着面は剥離紙９ａによって覆われている。そして、施工直前に剥離紙９ａがはがされて、他方の接着面が露出される（はがされた剥離紙が図１中一点鎖線で示される）。
【００２２】
次に、図８〜図１５および図３、図４を参照しつつ、物品取付具Ｍの壁面構成部材Ｈに対する取付手法について説明するが、その取付前の準備として、両面接着テープ９の剥離紙９ａがはがされる。また、治具兼用部材ＪＫが、アンカ片１、２を開口部１１内に挿通するときの邪魔とならないように、取付ボルト３の基端部側（アンカ片１、２とは反対側）に位置される（ただし保持部材４のねじ孔４ｂに取付ボルト３が螺合されている範囲）。
【００２３】
上述の事前準備が完了した後、まず、図２に示すように２つのアンカ片１、２を互いに重なるようにした状態として、図８に示すように、アンカ片１、２をその先端部側から開口部１１内に挿入させる。両アンカ片１と２とを重ね合わせたとき、第１アンカ片１の両面接着テープ９が第２アンカ片２に接触しないようにされる。この接触防止のために、例えば、第２アンカ片２をその基端部側（取付ボルト３側）から先端部側（自由端部側）に向かうにつれて徐々に第１アンカ片１から離間するようにわずかに傾斜させるようにしてもよく、逆に、第１アンカ片１をその先端部から基端部に向かうにつれて徐々に第２アンカ片２から離間するようにわずかに傾斜させるようにしてもよい。この他、両アンカ片１と２との間に薄いスペーサを介在させる等のことを行うこともできる。
【００２４】
図８の状態から、２つのアンカ片１、２をねじり込むようにしてさらに開口部１１内に深く挿入していく。この挿入の際、アンカ片１、２の湾曲形状設定によって、アンカ片が直線の場合に比して、壁面構成部材Ｈの裏面側に小さな間隔しかなくても挿入が可能である。このようにして２つのアンカ片１、２の開口部１１内への挿通が進んで、やがてアンカ片１、２は、図９に示すように、完全に開口部１１を通り抜けることになり、このときの壁面構成部材Ｈの表面側の様子が図１０に示される。
【００２５】
物品取付具Ｍから手を離しても、保持部材４のフランジ部４ｃが開口部１１の外周縁部に当接されて（係止されて）、物品取付具Ｍが壁面構成部材Ｈの裏面側において落下してしまうという事態は生じない。物品取付具Ｍから手を離した自由状態では、各アンカ片１、２は、重力によってその先端部が下方を向く回転姿勢位置となる。
【００２６】
両アンカ片１、２の先端部が下方を向いた回転姿勢位置状態から、取付ボルト３の基端部側を回転操作して、第１アンカ片１を回転させて、図１１に示すように、第２アンカ片２とは反対の上方へ向けて第１アンカ片１が伸びる回転姿勢位置状態とする。この状態で、一旦取付ボルト３を壁面構成部材Ｈの表面側へ引っ張ることにより、各アンカ片１、２の両面接着テープ９を壁面構成部材Ｈの裏面側に圧接させる。これにより、各アンカ片１、２の回転姿勢位置が位置決めされる。
【００２７】
次に、図１２に示すように、治具兼用部材ＪＫを、その突起部５ｃを利用して手動によって回転させて、アンカ片１、２に徐々に近づけていき、その保持部材４の筒部４ａが開口部１１内に挿入されるようにする。やがて、保持部材４のフランジ部４ｃが開口部１１の周縁部に当接する。フランジ部４ｃが開口部１１の周縁部に当接した状態からさらに強く治具兼用部材ＪＫを回転させると、その連結部８が破断されて、保持部材４と回転治具５とが分離される。このとき、第１アンカ片１と取付ボルト３との仮固定は解除されないままである。
【００２８】
この後、図１４に示すように、取付ボルト３に対して、物品取付用となる連結具２１が、スペーサ２２を介して袋ナット２３によって取付けられる。すなわち、連結具は、全体的に薄い円筒状とされて、その外周面２１ａに手摺り等の物品を固定するためのねじ部が形成されると共に、その内孔に取付ボルト３が貫通されるようになっている。
【００２９】
袋ナット２３を締め付けていくと、取付ボルト３に対する袋ナット２３の螺合進行はすぐにとまり、袋ナット２３に付与される締め付け力（回転力）は、保持部材４および第１アンカ片１に対する取付ボルト３の回転力として作用する。袋ナット２３に対する大きな締め付け力付与により、取付ボルト３と第１アンカ片１との仮固定が解除される。さらなる袋ナット２３への締め付け力付与により、取付ボルト３は、第１アンカ片１のねじ孔１ａに対する螺合が進行して、壁面構成部材Ｈに対して奥深くねじ込まれて、取付ボルト３の壁面構成部材Ｈからの突出量が徐々に小さくされていく。連結具の外周縁部が保持部材４のフランジ部４ｃの外側において壁面構成部材Ｈの表面側に強く押圧（着座）される取付状態となると、図１５に示す連結具の取付完了状態とされ、この取付完了状態での断面図が図４に示される（袋ナット２３による連結具２１の締め付けトルクは、例えば１０〜１３ｋｇｍ）。
【００３０】
以上の取付完了状態において、アンカ片１、２は、壁面構成部材Ｈの裏面側に圧接されるような方向の荷重は勿論のこと、剥離される方向の荷重、さらには壁面構成部材Ｈの裏面に沿って摺動（回転方向）される方向の荷重をも支承することができ、広い方向に渡っての荷重支承能力が大きなものとなる。ちなみに、図４の取付完了状態において、図示を略す物品からの荷重が下方向のときは（袋ナット２３に下方の荷重が作用するのと同じ）、上方に向けて伸びる第１アンカ片１が壁面構成部材Ｈの裏面側に圧接される方向の力を受けて荷重支承が十分に行われ、これに加えて、下方に向けて伸びる第２アンカ片２は壁面構成部材Ｈの裏面側から剥離される方向の力を受けるが、第２アンカ片２は両面接着テープ９の接着作用によって剥離することが規制されるので、この分荷重支承能力が従来よりも大きくなる。
【００３１】
取付けられる物品が水平手摺りの場合は、上記のように下方向の荷重が大きく、上方向にはあまり大きな荷重が作用しないが、このような場合においては両面接着テープ９は第２アンカ片２に対してのみ設ければ十分である。また、第１アンカ片１に両面接着テープ９を設けないことによって、アンカ片同士が接着してしまうおそれがなくなり、アンカ片の展開が容易かつ確実に行われる。
【００３２】
ここで、図４を参照しつつ、連結具２１を利用した物品としての手摺り３５を固定する一例について説明する。手摺り３５は、その端部にフランジ部３５ａを有し、このフランジ部３５ａに抜け止めされた状態で固定具３６が手摺り３５の端部に回転自在に嵌合されている。固定具３６は、キャップ状に形成されて、その内面に雌ねじ部３６ａが形成されており、この雌ねじ部３６ａが、連結具２１の外周に形成された雄ねじ部２１ａに螺合される。なお、手摺り３５のうち少なくともフランジ部３５ａ側の端部は筒状とされて、固定具３６を連結具２１に奥深く螺合させたときに、袋ナット２３が手摺り３５内に挿入状態とされる。
【００３３】
図１６は本発明の別の実施形態を示すもので、取付ボルト３の基端部側を拡大して示してあるが、取付ボルト３の外周面に形成されたねじ部は簡略化のために描かれていない。この図１６の例では、取付ボルト３の基端面に、係合凹部としての六角形状の係合孔４１を取付ボルト３の軸線方向に伸ばして形成してあり、この係合孔４１に六角レンチ等の回転工具が取付ボルト３の軸線回りに相対回転不能に係合されるようにしてある。そして、袋ナットの代わりに、取付ボルト３には通常の六角ナット４２を螺合させて、このナット４２によって連結具２１の締め付けを行うようにしてある。本実施形態では、係合孔４１に回転工具を係合させて、あらかじめ取付ボルト３の壁面構成部材Ｈの表面側からの突出長さを短くした後（第１アンカ片１と取付ボルト３との仮固定解除）、ナット４２による連結具２１の締め付けが行われる。
【００３４】
図１７も本発明の別の実施形態を示すものである。本実施形態では、アンカ片５１（アンカ片１、２対応）が、一本のみ用いられて、その形状はほぼまっすぐな細長板状とされている。このアンカ片５１の長手方向略中間部に、取付ボルト５２（取付ボルト３対応）の一端部が一体化されている（螺合なしで、溶接による完全一体化）。アンカ片５１のうち壁面構成部材Ｈの裏面側に向かう所定面には、両面接着テープ９があらかじめ設けられている。アンカ片５１は、開口部１１にその一端から挿入可能なように、取付ボルト５２からアンカ片５１の端部までの長さが開口部１１の直径よりも短く形成されるが、上下どちらか一方を長くして、長い方の片部より先に挿入するようにしてもよい。また、保持部材５３は、開口部１１の直径よりも大径となる円盤状の中心部に、物品取付用の連結部５３ａを一体に有している（連結部５３ａの外周部に連結用の雄ねじ部が形成されて、図４に示す連結具２１の機能を兼用している）。そして、保持部材５３の中心部分に、取付ボルト５２がスムーズに挿通される貫通孔５３ｂが形成されている。
【００３５】
本実施形態では、両面接着テープ９の剥離紙をはがした後、取付ボルト５２の基端部を把持しつつ、アンカ片５１を開口部１１に挿通させて壁面構成部材Ｈの裏面側に位置させる。この後、アンカ片５１が所定方向（例えば上下方向）に伸びる姿勢を保持しつつ、アンカ片５１の中央部に形成された隆起部５１ａを開口部１１に嵌合するようにして引き寄せて、両面接着テープ９でもってアンカ片５１を壁面構成部材Ｈの裏面側に接着する。開口部１１は、アンカ片５１の隆起部５１ａを嵌合する大きさに形成されており、この嵌合状態において取付ボルト５２が開口部１１のほぼ中心に位置される。また、アンカ片５１の隆起部５１ａが開口部１１に嵌合されるまでは、両面接着テープ９が隆起部５１ａによって壁面構成部材Ｈの裏面より離されており、不正な位置に接着されることが防止される。この後は、取付ボルト５２に保持部材５３を嵌合させた後、取付ボルト５２に螺合したロックナット５４によって、アンカ片５１と保持部材５３とで壁面構成部材Ｈを強く挟持させる状態として、取付完了となる。
【００３６】
図１８も本発明の別の実施形態を示すものである。本実施形態では、アンカ片６１としては、図１７の場合と同じような形状のものが１本のみ用いられるが、その長手方向中心部にねじ孔６２が形成されている。ねじ孔６２に螺合される取付ボルト６３は、その基端部に頭部６３ａを有するものとされている。アンカ片６１には保持用ひも６４が挿通される通し孔６５が形成されている。保持部材６６は、図１７の保持部材５３とほぼ同様に、外周に物品取付用の連結部（雄ねじ部）が形成されて、全体的に均一厚さの円盤状とされている。この保持部材６６は、取付ボルト６３の軸部がスムーズに挿通される貫通孔６６ａが形成されると共に、上記保持用ひも６４が挿通される通し孔６６ｂが形成されている。勿論、アンカ片６１のうち壁面構成部材Ｈの裏面側に向かう所定面には、両面接着テープ９が設けられている。
【００３７】
本実施形態においては、保持用ひも６４が図１８に示すように、アンカ片６１の通し孔６５および保持部材６６の通し孔６６ｂに挿通されて、連結されることにより、アンカ片６１が壁面構成部材Ｈの裏面側に落下してしまうことがない。なお、保持用ひも６４を把持して作業する場合は、必ずしも保持部材６６に保持用ひも６４が挿通されている必要はない。
【００３８】
両面接着テープ９の剥離紙がはがされた状態で、アンカ片６１が、開口部１１を通して、壁面構成部材Ｈの裏面側に挿入された後、保持用ひも６４によってアンカ片６１を引き寄せ、図１７の実施形態と同様にアンカ片６１の中央の隆起部６１ａを開口部１１に嵌合させると共に方向を整え、保持用ひも６４を強く引き、接着させる。その後、取付ボルト６３の軸部つまりねじ部を、保持部材６６の挿通孔６６ａ、開口部１１に挿通させて、アンカ片６１のねじ孔６２に螺合させる。取付ボルト６３の螺合進行により、やがてアンカ片６１と保持部材６６とで壁面構成部材Ｈが挟持される取付完了状態となる。このとき、取付ボルト３の頭部６３ａが、図１７におけるロックナット５４の機能を果たして、保持部材６６を押圧することになる。なお、保持用ひも６４は、取付ボルト６３をアンカ片６１のねじ孔６２に螺合した後で、かつ取付ボルト６３の頭部６３ａで保持部材６６を強く押圧する前の段階で、壁面構成部材Ｈの表面側から引き抜かれる。本実施形態では、開口部１１の大きさは、アンカ片６１の幅方向長さの直径でよく、またアンカ片６１の長さも図１７の実施形態に比して長く設定でき、取付強度を高めることができる。
【００３９】
以上実施形態について説明したが、物品としては、手摺りに限らず、照明器具等の各種電気製品等、壁面構成部材Ｈへの取付を行うことが要求される種々のものとすることができる。また、アンカ片と取付ボルトとの仮固定位置（取付ボルト３が螺合されるねじ孔１ａの形成位置）は、アンカ片の端部に限らず、アンカ片の長手方向ほぼ中間部に設定する等、適宜選択できるものである。勿論、アンカ片の形状は、開口部１１を挿通可能な適宜の形状を選択できる。さらに、両面接着テープ９に代えて、接着剤、特に速乾性の２液硬化型の接着剤を用いることもできる。取付ボルト３を利用した物品の固定手法は、実施形態に示すような連結具２１を利用する場合に限らず、例えば、ブラケットやハンガーのような物品をその背面部を保持部として直接取付ボルト３に固定する等、適宜の手法を選択できるものである。図１等に示す２つのアンカ片を用いる実施形態において、第１アンカ片１と取付ボルト３とを仮固定しないで、完全固定するようにしてもよい（取付ボルト３の螺合をすすめることによる取付ボルト３の壁面構成部材Ｈ表面側からの突出長さの調整なし）。本発明の目的は、明記されたものに限らず、実質的に好ましいあるいは利点として表現されたものを提供すること、および本発明の主要構成要素となる部品の提供をも暗黙的に含むものである。

BACKGROUND OF THE INVENTION
The present invention relates to an article attachment for attaching an article such as a handrail to the surface of a wall surface constituting member.
[0002]
[Prior art]
When attaching an object such as a handrail to the surface of the wall surface component, if the wall surface component is brittle, for example, gypsum board, it is attached from the surface side of the wall surface member attachment (surface on which the article is located) If the article is attached with a screw or the like, it becomes impossible to support a large load from the article and it cannot be adopted. For this reason, an opening is formed in the wall surface component member, the anchor piece is inserted through the opening portion and disposed on the back surface side of the wall surface component member, and the anchor piece is in close contact with the back surface side of the wall surface component member. A load from the article is supported.
[0003]
Conventionally, various types of article attachments using an anchor piece inserted through an opening have been proposed, but a holding member and an anchor piece arranged on the surface side of a wall surface component member are used as wall surface component members. There is a structure in which the wall surface constituting member is sandwiched between the anchor piece and the holding member by connecting through the mounting bolts inserted through the mounting bolts. And in the one having the mounting bolt, one end of the mounting bolt is connected to the anchor piece in advance, and the anchor piece is moved from the opening of the wall surface component member to the back side while holding the base end of the mounting bolt. Some have been made to perform the insertion work (see Japanese Patent Application Laid-Open No. 2000-145089).
[0004]
[Problems to be solved by the invention]
By the way, the support of the load from the article by the anchor piece is mainly handled when the anchor piece is pressed against the back surface side of the wall surface constituting member. For example, when the anchor piece is arranged so as to extend upward from the opening of the wall surface component member, the load is downward with respect to, for example, a handrail as an article arranged on the surface side of the wall surface component member and connected to the mounting bolt When the is acted, the anchor piece is pressed against the back surface side of the wall surface constituting member, and the load support is effectively performed. On the other hand, in the state where the anchor piece extends upward from the opening as described above, when an upward load is applied to the handrail, the anchor piece extending upward from the opening is applied to the anchor piece from the back side of the wall surface constituting member. Since the peeling force is received, this downward load support cannot be performed effectively.
[0005]
In order to solve such problems, the position of the anchor piece is set so as to extend in the direction opposite to the direction of the load acting on the article, assuming in advance the direction of the load acting on the article. In addition, the anchor piece is set so as to extend in both the upper and lower directions, for example, with the opening of the wall surface constituting member as a boundary so that it can cope with both upward and downward loads acting on the article. It has also been done.
[0006]
However, the load bearing using the anchor piece arranged on the back surface side of the wall surface component member is a load bearing using the pressure contact of the anchor piece to the back surface side of the wall surface component member, and is peeled off from the back surface side of the wall surface component member. Actually, it was not expected to be a load bearing in the direction to be done.
[0007]
The present invention has been made in view of the above circumstances, and the object thereof is to provide an anchor piece when a wall surface constituting member is sandwiched between an anchor piece and a holding member connected via a mounting bolt. It is an object of the present invention to provide an article fixture and parts thereof that can support a load in a wider direction.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, in the present invention (the invention according to claim 1) , the solution is as follows. That is, as described in claim 1 in the claims,
An anchor piece inserted through the opening formed in the wall surface component member and disposed on the back surface side of the wall surface component member and a holding member disposed on the surface side of the wall surface component member are inserted through the opening portion. An article mounting tool configured to sandwich the wall surface component member between the anchor piece and the holding member by connecting via a mounting bolt.
As the anchor piece, a first anchor piece and a second anchor piece are provided,
The front end of the mounting bolt is connected to the base end of the first anchor piece so as to rotate integrally,
The base end portion of the second anchor piece is rotatably fitted without being screwed to the mounting bolt on the base end side of the mounting bolt from the first anchor piece,
The first anchor piece and the second anchor piece have a predetermined surface extending toward the respective tip end portions, and can be brought into contact with the back surface side of the wall surface constituent member in a relative rotation posture that does not overlap each other. And when the first anchor piece and the second anchor piece overlap each other, one of the first anchor piece or the second anchor piece is the first anchor piece or the second anchor piece. The second anchor piece is inclined with respect to the other of the two anchor pieces, and the first anchor piece and the second anchor piece are set apart from each other based on the inclination;
An adhesive is provided on a predetermined surface of the first anchor piece to adhere to the back side of the wall surface constituting member, and the adhesive is configured so that the first anchor piece and the second anchor piece are mutually connected. In the overlapping relative rotation posture, one of the first anchor piece or the second anchor piece is inclined with respect to the other of the first anchor piece or the second anchor piece, and It is set so as not to touch . A preferred mode based on the above solution is as described in claim 2 and the following claims.
[0009]
【The invention's effect】
According to the invention described in claim 1, the anchor piece (at least the first anchor piece) is not only against the load pressed against the back surface side of the wall surface constituting member, but also the load to be peeled off, Furthermore, a load in a direction that slides on the back surface of the wall surface component can be supported, and a load in a wide direction can be supported. In addition, the adhesive is strongly pressed between the anchor piece and the back surface side of the wall surface constituent member with a connecting force using a mounting bolt, so that the adhesive is fixed by adhesion between the anchor piece and the back surface side of the wall surface constituent member. Is always ensured, and the above-described effects can be surely exhibited.
In addition, the second anchor piece has a posture that extends downward using its own weight, while the first anchor piece has a posture that extends upward by using the rotation operation of the mounting bolt, and the extension direction of the two anchor pieces is greatly increased. The difference is preferable in firmly supporting a load in a wider direction.
Further, when the first anchor piece and the second anchor piece are in a relative rotation posture in which the first anchor piece and the second anchor piece overlap each other, one of the first anchor piece or the second anchor piece is opposite to the other of the first anchor piece or the second anchor piece The adhesive provided on the predetermined surface of the first anchor piece is set so as not to contact the second anchor piece, and the first and second anchor pieces are inserted into the opening of the wall surface constituting member. In doing so, it is possible to prevent contact between the adhesive provided on the predetermined surface of the first anchor piece and the second anchor piece.
[0010]
According to the invention described in claim 2, the first and second anchor pieces are not only loaded in the direction in which they are pressed against the back surface side of the wall surface constituting member, but also loaded in the peeling direction, A load in the direction of sliding (rotating direction) along the rear surface of the wall surface component can also be supported, and the load bearing ability is increased over a wide direction .
[0011]
According to the invention described in claim 3 , the effect corresponding to claim 1 can be obtained by using the double-sided adhesive tape which is easy to handle.
According to the invention described in claim 4 , the holding member is a clamping member for clamping the wall surface constituting member, and a lock nut that is screwed to the mounting bolt and serves as a fixing tool for obtaining a predetermined clamping force. The function can be shared.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
1 to 12 showing the first embodiment of the present invention, components of the article fixture M will be described first. The article fixture M includes a first anchor piece 1, a second anchor piece 2, and a mounting bolt. 3 and a holding member 4. As will be described later, the holding member 4 serves as both a surface side member and a lock nut for cooperating with the anchor piece and sandwiching the wall surface constituent member. Sometimes, it is integrally formed with the rotating jig 5 in advance by a synthetic resin. In the following description, the integrated product of the holding member 4 and the rotating jig 5 will be described as a jig / member JK. In the embodiment, the article fixture M further includes a metal washer 6 and a spacer 7.
[0013]
Each of the anchor pieces 1 and 2 is formed into a slender and curved shape as a whole by a metal material (for example, a steel plate) or a synthetic resin (including a fiber reinforced synthetic resin-the same applies hereinafter) having a rigidity of several millimeters. It is said that. That is, each of the anchor pieces 1 and 2 has a shape curved in one direction as a whole. In particular, the degree of bending is strong on the tip end side, and the anchor pieces 1 and 2 are greatly bent in the lateral direction. Then, when the two anchor pieces 1 and 2 are rotated relative to each other around the mounting bolt 3 and overlapped with each other, the shape is set so that they are aligned so that they do not protrude from each other in the width direction (substantially congruent shapes). Setting).
[0014]
As shown in FIG. 5 in particular, a screw hole 1a is formed at the base end of the first anchor piece 1, and the tip of the mounting bolt 3 is screwed into the screw hole 1a. The mounting bolt 3 and the first anchor piece 1 are temporarily fixed in a state where the first anchor piece 1 is screwed to the tip of the mounting bolt 3. This temporary fixing is set so that the first anchor piece 1 and the mounting bolt 3 rotate integrally, and the fixing is released when a predetermined or higher relative torque is applied. In order to perform such temporary fixing, for example, it can be obtained by caulking as shown in FIG. 5 (the caulking portion is indicated by reference numeral k1).
[0015]
In the second anchor piece 2, the base end portion of the second anchor piece 2 (the mounting hole 2 a formed therein) is located closer to the base end portion of the mounting bolt 3 than the first anchor piece 1 with respect to the mounting bolt 3. It is fitted freely. That is, the second anchor piece 2 is freely rotatable without being screwed to the mounting bolt 3, and can be relatively rotated with respect to the first anchor piece 1 and the mounting bolt 3. Yes.
[0016]
As shown in FIGS. 3 and 4, each of the anchor pieces 1 and 2 is disposed on the back side of the wall surface constituent member H through the opening 11 formed in the wall surface structural member H. The wall pieces H are sandwiched between the anchor pieces 1 and 2 and the holding member 4 that are connected to each other, and the anchor pieces 1 and 2 are attached to the wall piece H. Note that this attachment work will be described later.
[0017]
The spacer 7 is made of, for example, synthetic resin, and corresponds to the difference in thickness of the wall surface constituting member H, that is, the difference in length of the opening 11, and between the second anchor piece 2 and the holding member 4. To the mounting bolt 3. That is, the spacer 7 is used when the wall surface constituting member H is thick, and is not used when the wall surface constituting member H is thin. The spacer 7 is formed with a notch 7a in the circumferential direction so that it can be easily attached to and detached from the attachment bolt 3 regardless of the attachment state of other members, and the attachment bolt is made using this notch 7a. 3 is removed and attached. In addition, the opening width of the notch 7a is made somewhat smaller than the diameter of the mounting bolt 3, and at the time of attachment and removal, the opening width of the notch 7a is increased by using elastic deformation. The washer 6 is for preventing the anchor piece 2 from directly contacting the spacer 7 or the holding member 4.
[0018]
As shown in FIGS. 1 and 2, a groove 3d extending in the radial direction is formed at the base end of the mounting bolt 3 so that a rotary tool such as a driver can be engaged. In order to arrange the first anchor piece 1 by rotating it 180 degrees, it can be visually confirmed by the rotational position of the groove 3d and the rotational position of the rotary tool.
[0019]
Details of the jig / member JK which is an integrated product of the holding member 4 and the rotating jig 5 are shown in FIGS. The holding member 4 is formed in a cylindrical portion 4a inserted into the opening 11, a screw hole 4b formed in the cylindrical portion 4a and screwed into the mounting bolt 3, and an opening formed in one end of the cylindrical portion 4a. 11 and an annular flange portion 4c having an outer diameter larger than the diameter of 11. The rotating jig 5 has a cylindrical main body 5a, and an inner hole of the main body 5a is a through hole 5b through which the mounting bolt 3 can be smoothly inserted. A plurality (two in the embodiment) of protrusions 5c for applying rotational force are formed on the outer periphery of the main body 5a at equal intervals in the circumferential direction.
[0020]
The holding member 4 and the rotating jig 5 are connected by a connecting portion 8. The connecting portion 8 is thin-walled and constitutes a weakened portion that is broken by receiving a torque of a predetermined level or more. Such a jig / member JK is integrally formed of synthetic resin (for example, injection molding). In order to configure the connecting portion 8 as a weakened portion that is broken by receiving a torque of a predetermined level or more, the connecting portion 8 is formed thinly in advance at the time of injection molding. An appropriate method can be adopted such as injection molding so that the tool 5 is coupled, or forming a groove portion on the outer periphery of the coupling portion 8 by machining after injection molding to make the coupling portion 8 thin.
[0021]
1 and 2 again, a double-sided adhesive tape 9 is affixed in advance to the surface of each anchor piece 1, 2 that faces the back side of the wall surface component H, and this double-sided adhesive tape 9. Is shown in FIG. 1 and FIG. 2 with hatching. The double-sided adhesive tape 9 serves as a rotational resistance applying means and a peeling prevention means. In the state before construction, one adhesive surface of the double-sided adhesive tape 9 is a predetermined surface of the anchor pieces 1 and 2 (of the wall constituting member H). The other adhesive surface is covered with the release paper 9a in advance. Then, the release paper 9a is peeled off just before the construction, and the other adhesive surface is exposed (the peeled release paper is indicated by a one-dot chain line in FIG. 1).
[0022]
Next, with reference to FIGS. 8 to 15 and FIGS. 3 and 4, a method for attaching the article fixture M to the wall surface constituting member H will be described. As a preparation before the attachment, the release paper of the double-sided adhesive tape 9 is used. 9a is removed. Further, on the base end side of the mounting bolt 3 (on the side opposite to the anchor pieces 1 and 2), the jig / member JK does not interfere with the insertion of the anchor pieces 1 and 2 into the opening 11. It is positioned (however, the range in which the mounting bolt 3 is screwed into the screw hole 4b of the holding member 4).
[0023]
After the above preparation is completed, first, the two anchor pieces 1 and 2 are overlapped with each other as shown in FIG. 2, and the anchor pieces 1 and 2 are placed on the tip side as shown in FIG. To be inserted into the opening 11. When the two anchor pieces 1 and 2 are overlapped, the double-sided adhesive tape 9 of the first anchor piece 1 is prevented from contacting the second anchor piece 2. In order to prevent this contact, for example, the second anchor piece 2 is gradually separated from the first anchor piece 1 as it goes from the base end side (mounting bolt 3 side) to the tip end side (free end side). In contrast, the first anchor piece 1 may be slightly inclined so as to gradually move away from the second anchor piece 2 from the distal end portion toward the proximal end portion. Good. In addition, a thin spacer can be interposed between the two anchor pieces 1 and 2.
[0024]
From the state of FIG. 8, the two anchor pieces 1 and 2 are further inserted deeply into the opening 11 so as to be twisted. At the time of this insertion, by setting the curved shape of the anchor pieces 1 and 2, insertion is possible even if there is only a small gap on the back surface side of the wall surface constituting member H as compared with the case where the anchor piece is a straight line. Thus, the insertion of the two anchor pieces 1 and 2 into the opening 11 proceeds, and eventually the anchor pieces 1 and 2 completely pass through the opening 11 as shown in FIG. FIG. 10 shows a state of the surface side of the wall surface constituting member H at the time.
[0025]
Even if the hand is released from the article fixture M, the flange portion 4c of the holding member 4 is abutted (locked) to the outer peripheral edge of the opening 11, and the article fixture M is on the back side of the wall surface component H. The situation of falling will not occur. In the free state in which the hand is released from the article attachment M, each anchor piece 1, 2 is in a rotational posture position in which the tip portion faces downward due to gravity.
[0026]
As shown in FIG. 11, the first anchor piece 1 is rotated by rotating the base end side of the mounting bolt 3 from the rotation posture position state in which the distal end portions of the two anchor pieces 1 and 2 are directed downward. , A rotation posture position state in which the first anchor piece 1 extends toward the upper side opposite to the second anchor piece 2. In this state, by temporarily pulling the mounting bolt 3 toward the front surface side of the wall surface constituting member H, the double-sided adhesive tape 9 of each anchor piece 1, 2 is pressed against the back surface side of the wall surface constituting member H. Thereby, the rotation posture position of each anchor piece 1 and 2 is positioned.
[0027]
Next, as shown in FIG. 12, the jig / member JK is rotated manually by using the protrusion 5c so as to gradually approach the anchor pieces 1 and 2, and the cylindrical portion of the holding member 4 4 a is inserted into the opening 11. Eventually, the flange portion 4 c of the holding member 4 comes into contact with the peripheral edge portion of the opening 11. When the jig / member JK is further strongly rotated from the state in which the flange portion 4c is in contact with the peripheral edge of the opening 11, the connecting portion 8 is broken and the holding member 4 and the rotating jig 5 are separated. . At this time, the temporary fixing of the first anchor piece 1 and the mounting bolt 3 remains unreleased.
[0028]
After that, as shown in FIG. 14, the connector 21 for attaching the article is attached to the attachment bolt 3 by the cap nut 23 via the spacer 22. That is, the coupling tool is formed into a thin cylindrical shape as a whole, and a screw portion for fixing an article such as a handrail is formed on the outer peripheral surface 21a, and the mounting bolt 3 is passed through the inner hole. It is like that.
[0029]
As the cap nut 23 is tightened, the progress of screwing of the cap nut 23 to the mounting bolt 3 immediately stops, and the tightening force (rotational force) applied to the cap nut 23 is applied to the holding member 4 and the first anchor piece 1. It acts as a rotational force of the mounting bolt 3. By applying a large tightening force to the cap nut 23, the temporary fixing of the mounting bolt 3 and the first anchor piece 1 is released. By further applying a tightening force to the cap nut 23, the mounting bolt 3 is screwed deeply into the wall surface component H as the first anchor piece 1 is screwed into the screw hole 1a, and the wall surface of the mounting bolt 3 is The amount of protrusion from the component H is gradually reduced. When the outer peripheral edge of the connector is in an attached state in which the outer peripheral edge of the connector 4 is strongly pressed (sitting) on the surface side of the wall surface constituting member H outside the flange portion 4c of the holding member 4, the attachment of the connector shown in FIG. FIG. 4 shows a cross-sectional view of this attachment completed state (the tightening torque of the connector 21 by the cap nut 23 is, for example, 10 to 13 kgm).
[0030]
In the mounting completion state described above, the anchor pieces 1 and 2 are not only loaded in the direction in which they are pressed against the back surface side of the wall surface component H, but also loaded in the direction of peeling, and further, the back surface of the wall surface component H It is also possible to support a load in a direction that is slid (rotated in the direction) along the direction, and the load supporting ability in a wide direction becomes large. Incidentally, when the load from the article (not shown) is in the downward direction in the attachment completion state of FIG. 4 (the same as the downward load acting on the cap nut 23), the first anchor piece 1 extending upward is Load support is sufficiently performed in response to the force in the direction pressed against the rear surface side of the wall surface component H. In addition, the second anchor piece 2 extending downward is peeled off from the rear surface side of the wall surface component H. However, since the second anchor piece 2 is restricted from being peeled off by the adhesive action of the double-sided adhesive tape 9, the load bearing capacity is increased compared to the conventional case.
[0031]
When the article to be attached is a horizontal handrail, the load in the downward direction is large as described above, and a large load is not applied in the upward direction. In such a case, the double-sided adhesive tape 9 is used as the second anchor piece 2. It is sufficient to provide only for. Further, since the double-sided adhesive tape 9 is not provided on the first anchor piece 1, there is no possibility that the anchor pieces are bonded to each other, and the anchor piece is easily and reliably developed.
[0032]
Here, an example of fixing the handrail 35 as an article using the connector 21 will be described with reference to FIG. The handrail 35 has a flange portion 35a at the end thereof, and a fixing tool 36 is rotatably fitted to the end portion of the handrail 35 in a state of being prevented from coming off by the flange portion 35a. The fixture 36 is formed in a cap shape, and an internal thread portion 36 a is formed on the inner surface thereof. The internal thread portion 36 a is screwed into an external thread portion 21 a formed on the outer periphery of the connector 21. Note that at least the end of the handrail 35 on the flange 35a side is cylindrical, and the cap nut 23 is inserted into the handrail 35 when the fixture 36 is screwed deeply into the connector 21. Is done.
[0033]
FIG. 16 shows another embodiment of the present invention, in which the proximal end side of the mounting bolt 3 is shown enlarged, but the threaded portion formed on the outer peripheral surface of the mounting bolt 3 is for simplicity. Not drawn. In the example of FIG. 16, a hexagonal engagement hole 41 as an engagement recess is formed on the base end surface of the attachment bolt 3 so as to extend in the axial direction of the attachment bolt 3. Such a rotating tool is engaged with the mounting bolt 3 so as not to rotate relative to the axis of the mounting bolt 3. Then, instead of the cap nut, a normal hexagonal nut 42 is screwed into the mounting bolt 3, and the coupling tool 21 is tightened by this nut 42. In this embodiment, after engaging a rotary tool with the engagement hole 41 and shortening the protrusion length from the surface side of the wall surface structural member H of the mounting bolt 3 in advance (the first anchor piece 1 and the mounting bolt 3 ), And the connector 21 is tightened by the nut 42.
[0034]
FIG. 17 also shows another embodiment of the present invention. In the present embodiment, only one anchor piece 51 (corresponding to the anchor pieces 1 and 2) is used, and the shape thereof is a substantially straight elongated plate shape. One end of a mounting bolt 52 (corresponding to the mounting bolt 3) is integrated with a substantially intermediate portion in the longitudinal direction of the anchor piece 51 (complete integration by welding without screwing). A double-sided adhesive tape 9 is provided in advance on a predetermined surface of the anchor piece 51 toward the back surface side of the wall surface component H. The anchor piece 51 is formed so that the length from the mounting bolt 52 to the end of the anchor piece 51 is shorter than the diameter of the opening 11 so that it can be inserted into the opening 11 from one end thereof. May be made longer and inserted before the longer one part. In addition, the holding member 53 integrally has a connecting portion 53a for attaching an article at a disc-shaped central portion having a diameter larger than the diameter of the opening portion 11 (for connecting to the outer peripheral portion of the connecting portion 53a). A male screw portion is formed, which also functions as the connector 21 shown in FIG. A through hole 53 b through which the mounting bolt 52 is smoothly inserted is formed in the central portion of the holding member 53.
[0035]
In this embodiment, after peeling off the release paper of the double-sided adhesive tape 9, the anchor piece 51 is inserted into the opening portion 11 while gripping the base end portion of the mounting bolt 52 and positioned on the back side of the wall surface component H. Let Thereafter, while the anchor piece 51 is held in a posture extending in a predetermined direction (for example, the vertical direction), the raised portion 51a formed at the center portion of the anchor piece 51 is drawn so as to be fitted to the opening portion 11, thereby The anchor piece 51 is bonded to the back surface side of the wall surface constituting member H with the adhesive tape 9. The opening 11 is formed in a size that fits the raised portion 51 a of the anchor piece 51, and the mounting bolt 52 is positioned substantially at the center of the opening 11 in this fitted state. Further, until the raised portion 51a of the anchor piece 51 is fitted into the opening 11, the double-sided adhesive tape 9 is separated from the back surface of the wall surface component H by the raised portion 51a and is bonded to an illegal position. Is prevented. After that, after the holding member 53 is fitted to the mounting bolt 52, the wall member H is firmly held between the anchor piece 51 and the holding member 53 by the lock nut 54 screwed to the mounting bolt 52. Installation is complete.
[0036]
FIG. 18 also shows another embodiment of the present invention. In the present embodiment, only one anchor piece 61 having the same shape as in FIG. 17 is used as the anchor piece 61, but a screw hole 62 is formed in the center in the longitudinal direction. The mounting bolt 63 screwed into the screw hole 62 has a head portion 63a at the base end portion. The anchor piece 61 is formed with a through hole 65 through which the holding cord 64 is inserted. As in the holding member 53 of FIG. 17, the holding member 66 has a connecting portion (male thread portion) for attaching an article on the outer periphery, and is formed into a disk shape having a uniform thickness as a whole. The holding member 66 has a through hole 66a through which the shaft portion of the mounting bolt 63 is smoothly inserted, and a through hole 66b through which the holding string 64 is inserted. Of course, the double-sided adhesive tape 9 is provided on a predetermined surface of the anchor piece 61 toward the back side of the wall surface constituting member H.
[0037]
In the present embodiment, as shown in FIG. 18, the holding cord 64 is inserted into and connected to the through hole 65 of the anchor piece 61 and the through hole 66 b of the holding member 66, so that the anchor piece 61 has a wall surface configuration. It does not fall to the back side of the member H. When the work is performed while holding the holding strap 64, the holding strap 64 is not necessarily inserted into the holding member 66.
[0038]
In a state where the release paper of the double-sided adhesive tape 9 is peeled off, the anchor piece 61 is inserted into the back surface side of the wall surface constituting member H through the opening 11, and then the anchor piece 61 is pulled by the holding cord 64. Similarly to the seventeenth embodiment, the central raised portion 61a of the anchor piece 61 is fitted into the opening 11, and the direction is adjusted, and the holding cord 64 is pulled strongly and bonded. Thereafter, the shaft portion, that is, the screw portion of the mounting bolt 63 is inserted into the insertion hole 66 a and the opening portion 11 of the holding member 66 and screwed into the screw hole 62 of the anchor piece 61. Due to the progress of the screwing of the mounting bolt 63, the wall surface constituting member H is finally clamped by the anchor piece 61 and the holding member 66. At this time, the head 63a of the mounting bolt 3 performs the function of the lock nut 54 in FIG. 17 and presses the holding member 66.

Although the embodiment has been described above, the article is not limited to a handrail, and may be various items that are required to be attached to the wall surface constituent member H, such as various electric products such as lighting fixtures. The temporary fixing position between the anchor piece and the mounting bolt (the formation position of the screw hole 1a into which the mounting bolt 3 is screwed) is not limited to the end portion of the anchor piece, but is set at a substantially intermediate portion in the longitudinal direction of the anchor piece. Etc., which can be appropriately selected. Of course, as the shape of the anchor piece, an appropriate shape that can be inserted through the opening 11 can be selected. Furthermore, instead of the double-sided adhesive tape 9, an adhesive, particularly a quick-drying two-component curable adhesive can be used. The article fixing method using the mounting bolt 3 is not limited to the case of using the connector 21 as shown in the embodiment. For example, the article such as a bracket or a hanger is directly attached to the mounting bolt 3 with the back part as a holding part. It is possible to select an appropriate method such as fixing to the above. In the embodiment using the two anchor pieces shown in FIG. 1 and the like, the first anchor piece 1 and the mounting bolt 3 may be completely fixed without being temporarily fixed (by moving the mounting bolt 3 into the screwed state). The protrusion length from the wall surface constituent member H surface side of the mounting bolt 3 is not adjusted). The object of the present invention is not limited to what is explicitly stated, but also implicitly includes providing what is substantially preferred or expressed as an advantage, and providing components that are the main components of the present invention.
