【発明の属する技術分野】
本願発明は、手摺用支柱の取付構造、特に傾斜面に立設するに好適な取付構造に関するものである。
【０００２】
【従来の技術】
通常、手摺を設置する場合、その側方に壁面が存在しないときは、設置面に支柱を所定間隔で立設し、これら各支柱の上端に手摺を架け渡して取り付けるのが通例である（特許文献１参照）。
【０００３】
この場合、設置面が水平に近いものであれば、支柱を設置面に対して略垂直（即ち、略鉛直）に立設すれば良く、従ってこの場合における支柱の取付構造は比較的簡単なもの（例えば、特許文献２参照）で良く、且つその取付作業性も容易である。
【０００４】
ところが、設置面が傾斜しているような場合には、例えば上掲特許文献１（図１参照）にも開示されるように、設置面の傾斜に拘わらず支柱を略鉛直に立設する必要があり、このため該支柱の設置面に対する取付角を適正に設定し且つこの設定された取付角を維持することができるように支柱の取付構造を設計することが要求される。
【０００５】
このような要求に応えるものとして従来より種々の構造が提案されている。例えば、上掲特許文献１には、凸形円弧面でなる固定面をもち且つ設置面側に固定される第１基礎部材と、該第１基礎部材の固定面に衝合可能な凹形円弧面状でなる受面をもつとともに支柱が取り付けられる第２基礎部材とを、上記第１基礎部材の固定面に上記第２基礎部材の受面を衝合させ且つこれら両者間の弧状方向における相対位置を適宜設定した状態（即ち、支柱の設置面に対する取付角を適正に設定した状態）でこれら両者間をボルト締結して固定するものが開示されている。尚、特許文献３にも、特許文献１に開示の取付構造に類似するものが開示されている。
【０００６】
また、特許文献４には、凸形弧状面にその軸心方向に延びる多数のセレーションを形成した第１の噛合部材を支柱の下端部に取り付ける一方、設置面側には凹形弧状面にその軸心方向に延びる多数のセレーションを形成した第２の噛合部材を設け、これら両者の噛合位置を適宜変更設定することで設置面に対する支柱の取付角を設定するとともに、これら二つの噛合部材間をボルト締結することでその取付角を維持するようにしたものが開示されている。

【０００８】
【発明が解決しようとする課題】
ところが、特許文献１及び特許文献３に開示される取付構造では、設置面に対する支柱の取付角の調整後における該取付角の維持が第１基礎部材の固定面と第２基礎部材の受面との間の摩擦力のみによって行われるので、手摺の使用状態での安定性あるいは信頼性という点において懸念の残るものである。
【０００９】
また、特許文献４に開示される取付構造では、二つの噛合部材の噛み合いによって取付角度を調整するものであることから、該各噛合部材の構造が複雑で製造コストが高くつくとともに、取付角度の調整時には両部材相互の噛合と噛合離脱とを何回か繰り返す必要があり、取付作業が煩雑で且つ作業性が悪いという問題があった。
【００１０】
そこで本願発明では、設置面に対する支柱の取付角の調整が容易で、且つ手摺使用上における安定性と信頼性の高い手摺用支柱の取付構造を提案することを目的としてなされたものである。
【００１１】
【課題を解決するための手段】
本願発明ではかかる課題を解決するための具体的手段として次のような構成を採用している。
【００１２】
▲１▼ 本願の第１の発明では、上端部２ｂに手摺１が取り付けられる支柱２を設置面Ｇに対してその下端部２ａ側に配置した支柱固定部３介して略鉛直に固定する手摺用支柱の取付構造において、上記支柱固定部３を、上記設置面Ｇ上に衝合固定される接地板４と、外周面に螺条１５が設けられた支持部材６であってその軸方向の一端面６ａには軸方向に最も突出する最突出部１７が設けられるとともに軸方向の他端面側には上記支柱２の下端部２ａが固定される支持部材６と、上記支持部材６の上記螺条１５に螺合される螺条１２を備えたナット部材５であってその外周側には該ナット部材５の軸方向に進退する複数個のボルト２３が取り付けられたナット部材５とで構成し、上記接地板４と上記支持部材６とを、該支持部材６の上記最突出部１７を上記接地板４に当接させた状態で結合ボルト２２により相対傾動可能に連結し且つ上記支持部材６の上記螺条１５部分に螺合させた上記ナット部材５の螺合量を調整することで該ナット部材５の下面５ａと上記支持部材６の上記最突出部１７との軸方向相対距離に応じて上記支持部材６に対する上記接地板４の取付角度が設定されるとともに、上記複数個のボルト２３の先端を上記接地板４に当接させることで上記取付角度が固定保持されるようにしたことを特徴としている。
【００１３】
従って、この発明の手摺用支柱の取付構造によれば、上記支柱２の下端部２ａに取り付けられた支持部材６と上記接地板４とを、該支持部材６の上記最突出部１７を上記接地板４に当接させた状態で結合ボルト２２により相対傾動可能に連結し、この状態で上記支持部材６の螺条１５部分に上記ナット部材５を螺合させ該ナット部材５の螺合量を調整することで、該ナット部材５の下面５ａと上記最突出部１７との軸方向相対距離が変化し、この相対距離の変化に伴って上記接地板４に対する上記支持部材６の取付角が変化することになる。
【００１４】
即ち、上記接地板４と上記支持部材６とが上記ボルト２２によって相対傾動可能に連結されており、しかも該ボルト２２を上記支持部材６の径方向に挟んだ両側において上記最突出部１７と上記ナット部材５の下面５ａとが当接することから、上記接地板４は、上記ボルト２２の連結点を中心として、上記最突出部１７と上記ナット部材５の下面５ａの双方に当接する姿勢に傾斜される。例えば、上記最突出部１７と該ナット部材５の下面５ａとの軸方向相対距離が無い場合（即ち、上記支持部材６の軸方向において上記最突出部１７の位置と上記ナット部材５の下面５ａの位置とが同じである場合）には、上記接地板４に対して上記支持部材６は垂直状態とされ且つ上記ナット部材５の下面５ａはその全周において上記接地板４に当接する。これに対して、上記の状態から、上記ナット部材５の螺回操作によってその下面５ａに対する上記最突出部１７の突出量が増加すると、これに伴って上記接地板４に対する上記支持部材６の取付角が増大方向に変化することになる。
【００１５】
このようにして上記支持部材６に対する上記ナット部材５の螺合量の調整によって上記接地板４に対する上記支持部材６の取付角を所要角度に設定した後は、上記複数個のボルト２３を締め込んでその先端を上記接地板４にそれぞれ当接させることで上記接地板４に対する上記支持部材６の取付角度が上記設定角度のまま固定保持されることになる。
【００１６】
しかる後、上記接地板４を設置面Ｇに接地させ且つこれを固定することで、上記支持部材６に取り付けられた上記支柱２は、上記設置面Ｇが傾斜しているにも拘わらず略鉛直に立設され、上記手摺１を安定的に且つ高い信頼性をもって支持することになる。
【００１７】
この支柱２の立設状態においては、上記接地板４と上記ナット部材５との間に配置された上記複数個のボルト２３によってこれら両者間の取付角が固定保持されており、しかもこの保持作用が上記ボルト２３の突っ張り作用によって実現されているので、例えばこれを摩擦力で実現する構成の場合に比して、その信頼性が高く、その結果、上記手摺１の使用状態における安定性及び信頼性が向上することになる。
【００１８】
また、上記接地板４に対する上記支持部材６の取付角の調整が上記ナット部材５の締め込みによって行われ、さらにこの取付角の固定保持が上記ナット部材５と上記接地板４の間に突っ張り状態で配置される上記ボルト２３によって行われるなど、簡単且つ安価な構成によって取付角の調整と取付角の固定保持とが実現されるものである。
【００１９】
▲２▼ 本願の第２の発明では、上記第１の発明に係る手摺用支柱の取付構造において、上記支持部材６の一端面６ａを上記最突出部１７を頂点とする傾斜面としたことを特徴としている。
【００２０】
従って、この発明の手摺用支柱の取付構造では、上記ナット部材５の締め込みによって上記接地板４に対する上記支持部材６の取付角が増加してその取付角と上記支持部材６の一端面６ａの傾斜角とが一致した状態においては、該一端面６ａと上記接地板４とが該一端面６ａの全周で当接し、上記取付角の固定保持作用が最も良好となり、上記手摺１の使用状態における安定性及び信頼性がより一層向上することになる。
【００２１】
【発明の効果】
以上のように、本願発明にかかる手摺用支柱の取付構造によれば、簡単且つ安価な構成によって上記接地板４に対する上記支持部材６（即ち、支柱２）の取付角を容易に設定し且つこれを安定的に固定保持することができ、この結果、使用上におけ安定的及び信頼性の高い手摺をより安価に提供することができる。
【００２２】
【発明の実施の形態】
以下、本願発明にかかる手摺用支柱の取付構造を好適な実施形態に基づいて具体的に説明する。
【００２３】
図１には、本願発明にかかる取付構造を適用して施工された手摺装置が示されている。この手摺装置は、所定の傾斜角度をもつ設置面Ｇに複数の支柱２，２，・・を略鉛直に立設し、これら各支柱２，２，・・の上端部２ｂに手摺１を架け渡して取り付けて構成される。そして、上記支柱２の下端部２ａを上記設置面Ｇに固定するために、本願発明の要旨たる支柱固定部３が用いられており、該支柱固定部３を用いることで、上記支柱２の上記接地板４に対する取付角を適正に設定し且つその固定保持を確実とし、もって使用上における安定性と信頼性の高い手摺装置を得ることができるものである。以下、上記支柱２及び上記支柱固定部３の構成等を図２以下を参照して具体的に説明する。
【００２４】
（ａ） 支柱２
上記支柱２は、図２及び図６に示すように、略楕円形の断面形状をもつ中空直管体で構成され、その下端部２ａが次述の支柱固定部３を介して上記設置面Ｇ上に固定される一方、その上端部２ｂには上記手摺１が取り付けられるようになっている。尚、この場合、上記支柱２は、その楕円断面の長軸方向が上記手摺１の軸方向に合致するように上記設置面Ｇ側への固定方向が設定されている。
【００２５】
（ｂ） 支柱固定部３
上記支柱固定部３は、上述のように、上記支柱２の下端部２ａを上記設置面Ｇに対して所定の取付角をもって固定するためのものであって、図２〜図３に示すように、接地板４とナット部材５と支持部材６とを備えて構成される。
【００２６】
（ｂ−１） 接地板４
上記接地板４は、所定径の円板体で構成され、且つその中心部分にはその下面側から上面側に***する***部７が設けられている。この***部７は、弧状断面を有する（図４参照）とともに、その頂上部には弧状方向に延びる左右一対の長穴８，８が、該弧状方向に直交する方向に適宜離間して設けられている。また、この接地板４の外周部には、該接地板４を上記設置面Ｇ側に締結固定するアンカーボルト２１（図４参照）を取り付けるためのボルト孔９が、該接地板４の周方向に所定間隔で設けられている。
【００２７】
（ｂ−２） 支持部材６
上記支持部材６は、その外周面に螺条１５を形成した円柱状の基部１３と、該基部１３の上面からこれと同軸上に延びる支持部１４とを備えて構成される。上記基部１３の下面１３ｂ（即ち、支持部材６の下面６ａ）は、その軸心に対して所定の傾斜角をもつ傾斜面とされており、該傾斜面のうち、軸方向外方へ最も突出する位置を最突出部１７としている。
【００２８】
また、上記基部１３の下面１３ｂには、その軸心を挟んで左右に所定間隔をもって（具体的には、上記接地板４の上記一対の長穴８，８の間隔と同一の間隔をもって）二つのボルト孔１８，１８（図４参照）が設けられている。
【００２９】
一方、上記支持部１４は、上記支柱２の下端部２ａを支持する部位であり、該支柱２の内側に密接嵌合し得るように、該支柱２と同様の略楕円形の外周断面を有している。そして、この場合、上記支持部１４の長軸方向と上記基部１３の下面１３ｂの傾斜面の長軸方向とが合致するように、上記基部１３と支持部１４との周方向における相対位置が設定されている。
【００３０】
（ｂ−３） ナット部材５
上記ナット部材５は、筒状体で構成され、その内周面に上記支持部材６の螺条１５に螺合する螺条１２を形成するとともに、その下面５ａ寄りの外周には径方向外方へ延出し且つボルト孔１１を備えた突片１０を該ナット部材５の周方向に等間隔で四個設けている。尚、この場合、上記突片１０は、その下面１０ａを、上記ナット部材５からその径方向外方へ遠ざかるに伴って、該ナット部材５の下面５ａと面一位置から次第に該ナット部材５の上面側へ後退するような傾斜面とされ、その傾斜角は上記支持部材６の下面６ａ、即ち上記基部１３の下面１３ｂの傾斜角と略同一に設定されている。また、上記突片１０に設けられる上記ボルト孔１１の軸心は、上記ナット部材５の軸心と平行とされている。
【００３１】
（ｃ） 組付手順
ここで、上記接地板４とナット部材５と支持部材６とで構成される上記支柱固定部３の組付手順を、組付完了状態を示す図３及び図４を参照しつつ説明する。
【００３２】
先ず、上記支持部材６の支持部１４に上記支柱２の下端部２ａを嵌挿し、これら両者を固定ビス２４，２４，・・によって固定する。この支持部材６の支持部１４への上記支柱２の取付状態においては、該支柱２の断面の長軸方向上に上記支持部材６側の上記最突出部１７が合致している。
【００３３】
次に、上記支持部材６の基部１３部分に上記ナット部材５を螺合させる（尚、この支持部材６への上記ナット部材５の螺合は、該支持部材６の支持部１４への上記支柱２の取付けに先立って行っても良い）。
【００３４】
しかる後、上記支持部材６の上記基部１３の下面１３ｂ側に、上記接地板４を取り付ける。即ち、上記接地板４の下面側から上記長穴８に結合ボルト２２を通しこれを上記支持部材６の下面６ａ（即ち、上記基部１３の下面１３ｂ）に設けたボルト孔１８にねじ込み、該結合ボルト２２によって上記接地板４と上記支持部材６とを仮止め状態で連結する。
【００３５】
この状態では、上記結合ボルト２２は上記接地板４側の長穴８の範囲内で上記***部７の弧状方向に移動可能となっているため、上記接地板４と上記支持部材６とは、上記長穴８の範囲内で相対傾動可能とされる。そして、上記接地板４に対する上記支持部材６の取付角は、上記結合ボルト２２を径方向に挟んでその両側に位置する上記支持部材６側の上記最突出部１７と、上記ナット部材５の下面５ａの一側部（即ち、上記最突出部１７の反対側に位置する側部）とが共に上記接地板４に当接した状態におけるこれら両部位間の上記支持部材６の軸方向の相対距離によって規定され、しかもこの相対距離を変化させることで上記取付角を増減調整することができるようになっている。
【００３６】
例えば、図４に示す状態においては、上記接地板４に上記支持部材６側の上記最突出部１７と上記ナット部材５の下面５ａの一側部とが共に当接しており、しかも上記最突出部１７の方が上記ナット部材５の下面５ａの一側部よりも下方へ突出していることから、上記接地板４は上記***部７における上記結合ボルト２２との係合部を中心として傾動し、該接地板４の上面に上記支持部材６側の上記最突出部１７と上記ナット部材５の下面５ａの一側部とが共に当接した角度位置に姿勢設定される。そして、この接地板４の姿勢、即ち、上記支持部材６の取付角は、上記ナット部材５の上記支持部材６に対する螺合量、換言すれば、上記支持部材６側の上記最突出部１７の上記ナット部材５の下面５ａからの突出量を変化させることで無段階で連続的に変化させることができるものである。
【００３７】
このように上記ナット部材５の上記支持部材６に対するねじ込み量を調整して所要の取付角を設定した後、上記結合ボルト２２をねじ込んで上記接地板４と上記支持部材６及び上記ナット部材５側に締結固定する。これで上記取付角の設定が完了する。しかる後、上記ナット部材５の上記各突片１０，１０，・・に取り付けた上記押ボルト２３をそれぞれねじ込んでその先端を上記接地板４に当接させる。これで、上記取付角が固定されそのまま保持される。
【００３８】
しかる後、上記接地板４を設置面Ｇ上に接地させ、これをアンカーボルト２１によって該設置面Ｇ側に固定するとともに、上記支柱固定部３部分に保護フード１６を被せて該支柱固定部３の外部への露出防止によって美観性を確保するとともに該支柱固定部３に人が接触する危険性を排除する。
【００３９】
以上で、上記接地板４に対する上記支持部材６の取付角の設定及び固定保持と、上記設置面Ｇへの設置作業がすべて完了する。後は、上記各支柱２，２，・・の上端部２ｂに上記手摺１を架け渡して固定することで手摺装置が完成される。
【００４０】
ところで、この実施形態においては、上記接地板４に対する上記支持部材６の取付角を、図５に示す「最大角度位置」と図８に示す「最小角度位置」との間で任意に且つ無段階に設定できるようにしており、そのため、上記支持部材６の基部１３の下面１３ｃの傾斜角を上記「最大角度位置」における取付角に合致させるように設定している。
【００４１】
従って、図５に示す「最大角度位置」においては、上記支持部材６の上記基部１３の下面１３ｃがその全域において上記接地板４に当接するとともに、例えば上記ナット部材５側の上記各突片１０，１０，・・のうちの一つが上記最突出部１７の反対位置に位置している場合（図５に示す状態）には、該突片１０の下面１０ａが上記接地板４に当接する。このため、この「最大角度位置」においては、上記押ボルト２３を作用させずとも上記取付角の固定保持が良好に行われるが、さらに上記押ボルト２３を作用させることで該固定保持がより一層強固となりその確実性が増すことになる。
【００４２】
一方、図８に示す「最小角度位置」においては、上記ナット部材５の下面５ａの全域が上記接地板４に当接することで上記取付角の固定保持が確実に行われる。従って、この場合には上記押ボルト２３を作用させる必要はなく、それだけ取付け作業の簡便化が図れることになる。
【００４３】
また、図７に示す「中間角度位置」においては、上記接地板４に対する上記支持部材６の取付角が上記支持部材６側の上記基部１３の下面１３ｂの傾斜角よりも小さいため、上記接地板４に対する上記支持部材６側の当接位置は、該支持部材６側の上記最突出部１７と上記ナット部材５の下面５ａの一側部の二点のみである。
【００４４】
従って、この状態では、上記支柱２は、上記設置面Ｇの傾斜方向においては上記二点で抵抗するため比較的良好な姿勢保持作用が得られるものの、上記設置面Ｇの傾斜方向に直交する方向（即ち、手摺１を横倒しする方向）においては抵抗力が弱い。このため、この「中間角度位置」においては、上記押ボルト２３による突っ張り作用が最も有効に作用することになる。
【００４５】
即ち、上記各突片１０，１０，・・のうち、上記接地板４に当接する位置にあるものを除いてその全てにそれぞれ押ボルト２３を取付け、これらをねじ込んで上記接地板４との間でそれぞれ突っ張らせることで、上記取付角の固定保持がより強固に行われることになり、上記「最大角度位置」及び「最小角度位置」のときと同様に、上記支柱２の上記設置面Ｇへの取付けが安定的に且つ高い信頼性をもって行われ、延いては手摺装置としての信頼性が向上することになる。
【００４６】
（ｄ） その他
この実施形態においては、上記突片１０，１０，・・を上記ナット部材５と一体的に設けているが、本願発明はかかる構成に限定されるものではなく、たの実施形態においては、例えば上記各突片１０，１０，・・を上記ナット部材５とは別体に形成し、該ナット部材５に対して相対回転自在に取り付けるようにすることもできる。このようにした場合には、上記各突片１０，１０，・・を適宜回転させてその設置位置を選択することで、上記押ボルト２３による突っ張り作用を上記支柱２の姿勢保持上最も有効に作用する位置に設定することができ、より一層安定性及び信頼性の高い手摺装置を得ることができる。
【００４７】
また、この実施形態においては、上記支持部材６の下面、即ち上記基部１３の下面１３ｃを傾斜面とし、その頂点部分を上記最突出部１７としているが、本願発明はかかる構成に限定されるものではなく、少なくとも上記基部１３の下面１３ｃに上記最突出部１７が設けられておれば足り、例えば上記基部１３の下面１３ｃをその軸心に直交する端面として形成しその周方向の一部に突出部を形成してこれを上記最突出部１７として用いることもできるものである。

BACKGROUND OF THE INVENTION
The present invention relates to a mounting structure for a handrail support, and particularly to a mounting structure suitable for standing on an inclined surface.
[0002]
[Prior art]
Normally, when installing a handrail, if there is no wall on the side of the handrail, it is customary to stand upright pillars on the installation surface at a predetermined interval, and to install the handrails over the upper ends of these pillars (patents) Reference 1).
[0003]
In this case, if the installation surface is nearly horizontal, the support column may be erected substantially perpendicular to the installation surface (that is, substantially vertical), and therefore the support mounting structure in this case is relatively simple. (See, for example, Patent Document 2), and its mounting workability is also easy.
[0004]
However, in the case where the installation surface is inclined, for example, as disclosed in the above-mentioned Patent Document 1 (see FIG. 1), it is necessary to stand the column substantially vertically regardless of the inclination of the installation surface. For this reason, it is required to design the mounting structure of the column so that the mounting angle of the column with respect to the installation surface can be appropriately set and the set mounting angle can be maintained.
[0005]
Conventionally, various structures have been proposed to meet such demands. For example, in the above-mentioned Patent Document 1, a first base member having a fixed surface formed of a convex arc surface and fixed to the installation surface side, and a concave arc that can collide with the fixed surface of the first base member. A second base member having a planar receiving surface and to which a support post is attached, abutting the receiving surface of the second basic member on the fixed surface of the first basic member and relative to each other in the arcuate direction A device is disclosed in which a position is appropriately set (that is, a mounting angle of a support column with respect to an installation surface is appropriately set) and a bolt is fastened between the two. Patent Document 3 also discloses a similar structure to the mounting structure disclosed in Patent Document 1.
[0006]
Further, in Patent Document 4, a first engagement member formed with a number of serrations extending in the axial direction on a convex arc-shaped surface is attached to the lower end portion of the support column, while the installation surface side has a concave arc-shaped surface. A second engagement member having a number of serrations extending in the axial direction is provided, and the attachment angle of the column with respect to the installation surface is set by appropriately changing the engagement position between the two, and between the two engagement members The thing which maintained the attachment angle by fastening with a volt | bolt is disclosed.

Japanese Patent Laid-Open No. 10-299212 [Patent Document 4]
Japanese Patent Application Laid-Open No. 11-81606.
[0008]
[Problems to be solved by the invention]
However, in the mounting structures disclosed in Patent Document 1 and Patent Document 3, the maintenance of the mounting angle after the adjustment of the mounting angle of the column with respect to the installation surface is performed by the fixing surface of the first base member and the receiving surface of the second base member. Therefore, there is a concern in terms of stability or reliability in the state of use of the handrail.
[0009]
Further, in the mounting structure disclosed in Patent Document 4, since the mounting angle is adjusted by the engagement of two meshing members, the structure of each meshing member is complicated and the manufacturing cost is high. At the time of adjustment, it is necessary to repeat the engagement and disengagement between the two members several times, and there is a problem that the mounting operation is complicated and the workability is poor.
[0010]
In view of this, the present invention has been made for the purpose of proposing a mounting structure for a handrail support that is easy to adjust the mounting angle of the support with respect to the installation surface and that is highly stable and reliable in the use of the handrail.
[0011]
[Means for Solving the Problems]
In the present invention, the following configuration is adopted as a specific means for solving such a problem.
[0012]
(1) In the first invention of the present application, for the handrail for fixing the support column 2 to which the handrail 1 is attached to the upper end portion 2b substantially vertically through the support column fixing portion 3 arranged on the lower end portion 2a side with respect to the installation surface G. In the column mounting structure, the column fixing portion 3 includes a grounding plate 4 that is abutted and fixed on the installation surface G, and a support member 6 provided with a screw 15 on the outer peripheral surface, and has one axial direction. The end surface 6a is provided with the most protruding portion 17 that protrudes most in the axial direction, and the lower end portion 2a of the support column 2 is fixed to the other end surface side in the axial direction, and the thread of the support member 6 A nut member 5 having a thread 12 that is screwed to 15, and a nut member 5 having a plurality of bolts 23 attached to the outer peripheral side of the nut member 5 that advance and retreat in the axial direction of the nut member 5. The ground plate 4 and the support member 6 are connected to the outermost protrusion of the support member 6. With the projecting portion 17 in contact with the ground plate 4, the amount of screwing of the nut member 5, which is connected so as to be relatively tiltable by the coupling bolt 22 and screwed to the screw 15 portion of the support member 6, is determined. By adjusting, the mounting angle of the grounding plate 4 with respect to the support member 6 is set according to the axial relative distance between the lower surface 5a of the nut member 5 and the most protruding portion 17 of the support member 6. The mounting angle is fixed and held by bringing the tips of a plurality of bolts 23 into contact with the ground plate 4.
[0013]
Therefore, according to the attachment structure of the handrail support of the present invention, the support member 6 attached to the lower end 2a of the support 2 and the ground plate 4 are connected to the most projecting portion 17 of the support member 6. In a state of being brought into contact with the main plate 4, the coupling bolt 22 is connected so as to be relatively tiltable, and in this state, the nut member 5 is screwed into the thread 15 portion of the support member 6, and the screwing amount of the nut member 5 is set. By adjusting, the axial relative distance between the lower surface 5a of the nut member 5 and the most projecting portion 17 changes, and the mounting angle of the support member 6 with respect to the ground plate 4 changes as the relative distance changes. Will do.
[0014]
That is, the ground plate 4 and the support member 6 are connected to each other so as to be relatively tiltable by the bolt 22, and on the both sides of the bolt 22 in the radial direction of the support member 6, Since the lower surface 5 a of the nut member 5 abuts, the grounding plate 4 is inclined so as to abut on both the most protruding portion 17 and the lower surface 5 a of the nut member 5 with the connection point of the bolt 22 as the center. Is done. For example, when there is no axial relative distance between the most protruding portion 17 and the lower surface 5a of the nut member 5 (that is, the position of the most protruding portion 17 and the lower surface 5a of the nut member 5 in the axial direction of the support member 6). The support member 6 is in a vertical state with respect to the ground plate 4, and the lower surface 5a of the nut member 5 is in contact with the ground plate 4 on the entire circumference thereof. On the other hand, when the protrusion amount of the most protruding portion 17 with respect to the lower surface 5a is increased by the screwing operation of the nut member 5 from the above state, the attachment of the support member 6 to the ground plate 4 is accompanied accordingly. The angle will change in the increasing direction.
[0015]
After the mounting angle of the support member 6 to the ground plate 4 is set to a required angle by adjusting the screwing amount of the nut member 5 to the support member 6 in this manner, the plurality of bolts 23 are tightened. Then, the front end of each of the support members 6 is brought into contact with the ground plate 4 so that the mounting angle of the support member 6 with respect to the ground plate 4 is fixed and held at the set angle.
[0016]
Thereafter, the grounding plate 4 is grounded to and fixed to the installation surface G, so that the support column 2 attached to the support member 6 is substantially vertical even though the installation surface G is inclined. The handrail 1 is supported stably and with high reliability.
[0017]
In the standing state of the support column 2, the mounting angle between the two is fixed and held by the plurality of bolts 23 arranged between the ground plate 4 and the nut member 5. Is realized by the tensioning action of the bolt 23, for example, the reliability is higher than in the case of a configuration in which this is realized by a frictional force, and as a result, the stability and reliability in the use state of the handrail 1 as a result. Will be improved.
[0018]
Further, the mounting angle of the support member 6 with respect to the ground plate 4 is adjusted by tightening the nut member 5, and the mounting angle is fixedly held between the nut member 5 and the ground plate 4. The mounting angle can be adjusted and the mounting angle can be fixed and held by a simple and inexpensive configuration.
[0019]
(2) In the second invention of the present application, in the handrail post mounting structure according to the first invention, the one end surface 6a of the support member 6 is an inclined surface having the most projecting portion 17 as a vertex. It is a feature.
[0020]
Therefore, in the mounting structure of the handrail support of the present invention, the mounting angle of the support member 6 with respect to the ground plate 4 is increased by tightening the nut member 5, and the mounting angle and the one end surface 6a of the support member 6 are increased. In a state where the inclination angles coincide with each other, the one end face 6a and the ground plate 4 abut on the entire circumference of the one end face 6a, and the fixing and holding action of the mounting angle becomes the best, and the handrail 1 is used. The stability and reliability in the case will be further improved.
[0021]

The position to be used is the most protruding portion 17.
[0028]
Further, the lower surface 13b of the base portion 13 has a predetermined interval left and right across the axis (specifically, with the same interval as the interval between the pair of long holes 8 and 8 of the ground plate 4). Two bolt holes 18, 18 (see FIG. 4) are provided.
[0029]
On the other hand, the support portion 14 is a portion that supports the lower end portion 2a of the support column 2 and has a substantially elliptical outer peripheral section similar to that of the support column 2 so that the support portion 14 can be closely fitted inside the support column 2. doing. In this case, the relative position in the circumferential direction of the base portion 13 and the support portion 14 is set so that the long axis direction of the support portion 14 matches the long axis direction of the inclined surface of the lower surface 13b of the base portion 13.

Four projecting pieces 10 extending to the top and provided with bolt holes 11 are provided at equal intervals in the circumferential direction of the nut member 5. In this case, the protruding piece 10 gradually moves from the same position as the lower surface 5a of the nut member 5 as the lower surface 10a moves away from the nut member 5 radially outward. The inclined surface retreats to the upper surface side, and the inclination angle is set to be substantially the same as the inclination angle of the lower surface 6 a of the support member 6, that is, the lower surface 13 b of the base portion 13. The axial center of the bolt hole 11 provided in the projecting piece 10 is parallel to the axial center of the nut member 5.
[0031]
(C) Assembly procedure Here, refer to FIG. 3 and FIG. 4 showing the assembly completion state for the assembly procedure of the column fixing part 3 composed of the ground plate 4, the nut member 5 and the support member 6. However, it will be explained.
[0032]
First, the lower end 2a of the support column 2 is fitted into the support portion 14 of the support member 6, and both of them are fixed by fixing screws 24, 24,. When the support column 2 is attached to the support portion 14 of the support member 6, the most projecting portion 17 on the support member 6 side is aligned with the longitudinal direction of the cross section of the support column 2.
[0033]
Next, the nut member 5 is screwed into the base 13 portion of the support member 6 (note that the nut member 5 is screwed to the support member 6 in the support column 14 to the support portion 14. 2 may be performed prior to installation of 2).
[0034]
Thereafter, the ground plate 4 is attached to the lower surface 13b side of the base 13 of the support member 6. That is, a coupling bolt 22 is inserted into the elongated hole 8 from the lower surface side of the ground plate 4 and screwed into a bolt hole 18 provided on the lower surface 6a of the support member 6 (that is, the lower surface 13b of the base portion 13). The ground plate 4 and the support member 6 are connected in a temporarily fixed state by bolts 22.
[0035]
In this state, since the coupling bolt 22 is movable in the arcuate direction of the raised portion 7 within the range of the long hole 8 on the ground plate 4 side, the ground plate 4 and the support member 6 are Relative tilting is possible within the range of the long hole 8. The mounting angle of the support member 6 with respect to the ground plate 4 is such that the most projecting portions 17 on the support member 6 side located on both sides of the coupling bolt 22 in the radial direction and the bottom surface of the nut member 5. The relative distance in the axial direction of the support member 6 between these two parts in a state where one side part of 5a (that is, the side part located on the opposite side of the most projecting part 17) is in contact with the ground plate 4 together. In addition, the mounting angle can be increased or decreased by changing the relative distance.
[0036]
For example, in the state shown in FIG. 4, the most protruding portion 17 on the support member 6 side and one side portion of the lower surface 5a of the nut member 5 are in contact with the ground plate 4 and the most protruding portion is provided. Since the portion 17 protrudes downward from one side portion of the lower surface 5a of the nut member 5, the ground plate 4 tilts around the engaging portion with the coupling bolt 22 in the raised portion 7. The posture is set at an angular position where the uppermost protruding portion 17 on the support member 6 side and one side portion of the lower surface 5a of the nut member 5 are in contact with the upper surface of the ground plate 4. And the attitude | position of this grounding board 4, ie, the attachment angle of the said supporting member 6, is the screwing amount of the said nut member 5 with respect to the said supporting member 6, in other words, the said most protruding part 17 of the said supporting member 6 side. The amount of protrusion from the lower surface 5a of the nut member 5 can be changed continuously and steplessly.
[0037]
Thus, after adjusting the screwing amount of the nut member 5 to the support member 6 to set a required mounting angle, the coupling bolt 22 is screwed to the ground plate 4, the support member 6, and the nut member 5 side. Fasten and fix to. This completes the setting of the mounting angle. Thereafter, the push bolts 23 attached to the projecting pieces 10, 10,... Of the nut member 5 are screwed in, and their tips are brought into contact with the ground plate 4. Thus, the mounting angle is fixed and held as it is.
[0038]
Thereafter, the ground plate 4 is grounded on the installation surface G and fixed to the installation surface G by the anchor bolt 21, and the support fixing portion 3 is covered with a protective hood 16 to cover the support fixing portion 3. By preventing exposure to the outside, aesthetics are ensured and the risk of human contact with the column fixing portion 3 is eliminated.
[0039]
Thus, the setting and fixing of the mounting angle of the support member 6 with respect to the ground plate 4 and the installation work on the installation surface G are completed. Thereafter, the handrail device is completed by spanning and fixing the handrail 1 to the upper end portion 2b of each of the supports 2, 2,.
[0040]
By the way, in this embodiment, the mounting angle of the support member 6 with respect to the ground plate 4 is arbitrarily and steplessly between the “maximum angle position” shown in FIG. 5 and the “minimum angle position” shown in FIG. Therefore, the inclination angle of the lower surface 13c of the base portion 13 of the support member 6 is set to match the mounting angle at the “maximum angle position”.
[0041]
Therefore, in the “maximum angle position” shown in FIG. 5, the lower surface 13 c of the base portion 13 of the support member 6 is in contact with the ground plate 4 over the entire area, and, for example, the projecting pieces 10 on the nut member 5 side. , 10,... Is located at a position opposite to the most projecting portion 17 (the state shown in FIG. 5), the lower surface 10a of the projecting piece 10 contacts the ground plate 4. For this reason, in this “maximum angle position”, the mounting angle is fixed and held satisfactorily without applying the push bolt 23, but by further applying the push bolt 23, the fixing and holding is further improved. It will become stronger and its certainty will increase.
[0042]
On the other hand, in the “minimum angular position” shown in FIG. 8, the entire area of the lower surface 5a of the nut member 5 is in contact with the ground plate 4, so that the mounting angle is securely fixed. Therefore, in this case, it is not necessary to operate the push bolt 23, and the mounting work can be simplified accordingly.
[0043]
Further, in the “intermediate angle position” shown in FIG. 7, the mounting angle of the support member 6 with respect to the ground plate 4 is smaller than the inclination angle of the lower surface 13b of the base 13 on the support member 6 side. 4, there are only two contact positions on the side of the support member 6, that is, the most protruding portion 17 on the side of the support member 6 and one side of the lower surface 5 a of the nut member 5.
[0044]
Accordingly, in this state, the support column 2 resists at the two points in the inclination direction of the installation surface G, so that a relatively good posture maintaining action is obtained, but a direction orthogonal to the inclination direction of the installation surface G is obtained. In other words, the resistance is weak in the direction in which the handrail 1 is laid down. For this reason, at this “intermediate angular position”, the tension action by the push bolt 23 is most effective.
[0045]
That is, push bolts 23 are attached to all of the projecting pieces 10, 10,... Except for the ones that are in contact with the ground plate 4, and these are screwed into the ground plate 4. The mounting angle is fixed and held more firmly, and, similarly to the case of the “maximum angle position” and the “minimum angle position”, the mounting surface G of the column 2 is fixed to the installation surface G. Is stably and highly reliable, and as a result, the reliability of the handrail device is improved.
[0046]
(D) Other In this embodiment, the projecting pieces 10, 10,... Are integrally provided with the nut member 5, but the present invention is not limited to such a configuration, and the present embodiment In this case, for example, the projecting pieces 10, 10,... May be formed separately from the nut member 5 and attached to the nut member 5 so as to be relatively rotatable. In this case, the projecting action by the push bolt 23 is most effective in maintaining the posture of the support column 2 by appropriately rotating the projecting pieces 10, 10,. It can be set to the position where it acts, and a handrail device with higher stability and reliability can be obtained.
[0047]
Further, in this embodiment, the lower surface of the support member 6, that is, the lower surface 13c of the base portion 13 is an inclined surface and the apex portion is the most projecting portion 17, but the present invention is limited to such a configuration. Instead, it is sufficient that the most protruding portion 17 is provided at least on the lower surface 13c of the base portion 13. For example, the lower surface 13c of the base portion 13 is formed as an end surface orthogonal to the axis and protrudes to a part in the circumferential direction. A portion can be formed and used as the most protruding portion 17.
