【発明の属する技術分野】
本発明は、階段に手すりを取り付ける手すりの取付構造に関する。
【０００２】
【従来の技術】
従来、図４に示すように、階段２１の昇降方向に沿って手すり子２２を連設し、この手すり子２２の上端に沿って手すり２３を架設し、手すり子２２の手すり下方に横桟２４を架設支持させてなる手すりの取付構造が示されている。横桟２４は隣接する手すり子２２の側面間に手すり２３と平行に設けられており、横桟端部２５が手すり子の側面の中心よりも外側位置に固定されている。（実開平３−６６３３６号公報参照）

【発明が解決しようとする課題】
しかしながら上記従来の手すりの取付構造では、傾斜角度の異なる他の階段に同仕様の手すり子及び横桟を適用しようとすると、手すりが手すり子上端中央に固定され、横桟端部が手すり子の側面の中心よりも外側位置に固定されているため、手すり、隣接する手すり子及び横桟で形成される４角形が平行四辺形にならず、階段の傾斜角度によっては手すりと横桟が平行にならず外観を損なうことがあり、この場合、横桟を手すりと平行にするためには、横桟の手すり子への固定位置を手すりと横桟が平行になるよう上下に微調整しなければならず、その調整作業がめんどうであるという問題がある。
【０００５】
本発明は、上記事由に鑑みてなされたものであり、その目的は、傾斜角度の異なる他の階段に適用しても、手すり子への横桟の取付位置を変更することなく、手すりと横桟が平行にできる手すりの取付構造を提供することにある。
【０００６】
【課題を解決するための手段】
本願発明は、階段の昇降方向に沿って手すり子を連設し、この手すり子の上端に沿って手すりを架設し、手すり子の手すり下方に横桟を架設支持させてなる手すりの取付構造であって、手すり子の側面の横幅中心位置に横桟を上下方向に回動自在に支持する支持軸を設けてなる手すりの取付構造であり、手すり子の階段昇降方向に貫通孔を設け、この貫通孔に支持軸を介して上下方向に回動自在に取付部材を設け、この取付部材に横桟を取り付けてなり、横桟が管状部材から形成され、取付部材にこの横桟の端部開口部が挿入固定される固定部を設けてなることを特徴として構成している。
【０００７】
このような手すりの取付構造では、手すり子の側面の横幅中心位置に横桟を上下方向に回動自在に支持する支持軸を設けているので、手すり、隣接する手すり子及び横桟で形成される４角形が平行四辺形となり、階段の傾斜角度が異なってもその傾斜角度に合わせて平行四辺形の角度が異なるだけであり、手すりと横桟との平行関係は保持される。
【０００９】
更に、本願発明では、手すり子の貫通孔に支持軸により回動自在に設けた取付部材に横桟を取り付けているので、階段の傾斜角度が異なって隣接する手すり子間の横桟長さが異なっても、横桟長さを適切な長さに切断調整して取付部材に取り付けることにより、簡単に横桟を支持軸により回動自在とすることができる。
【００１１】
更に、本願発明では、横桟が管状部材から形成されているので、横桟を任意の場所で切断しても横桟の端部開口部を取付部材の固定部に挿入固定することにより、簡単に横桟を取付部材に取り付けることができる。
【００１２】
【発明の実施の形態】
以下、本発明の実施形態の手すりの取付構造を図１乃至図３に基づいて説明する。
【００１３】
図１は、本発明の実施形態の手すりの取付構造を示す要部の分解斜視図である。また図２は、同上の手すりの取付構造を示す斜視図（手すり図示せず）である。また図３は、同上の手すりの取付構造を示す側面図である。
【００１４】
図１乃至図３に示すように、この手すりの取付構造は、階段１の昇降方向に沿って手すり子２を連設し、この手すり子２の上端に沿って手すり３を架設し、手すり子２の手すり３下方に横桟４を架設支持させてなる手すりの取付構造であり、手すり子２側面の横幅中心位置に横桟４を上下方向に回動自在に支持する支持軸５を設けている。また、手すり子２の階段昇降方向に貫通孔６を設け、この貫通孔６に支持軸５を介して上下方向に回動自在に取付部材７を設け、この取付部材７に横桟４を取り付けている。また、横桟４が管状部材から形成され、取付部材７にこの横桟４の端部開口部が挿入固定される固定部７ｂを設けている。
【００１５】
手すり子２は、階段１の踏板１ａの上面端部にビス固定される取付台９と、この取付台９に立設される長尺の金属製略角パイプからなる本体部２ａと、から形成されている。取付台９は、踏板１ａにビス固定するためのビス固定孔を有する下板９ｂと、この下板９ｂ上に立設され本体部２ａの下端開口部が挿入固定される保持部９ａとを有している。下板９ｂは、本体部２ａと略同形状の外形を有しており、保持部９ａに本体部２ａを挿入固定したときに、下板９ｂ外面と本体部２ａ外面とが略面一になるようにして外観をすっきりしたものにしている。また、保持部９ａの外形は保持部９ａの内部開口形状と略同形状の外形を有しており、保持部９ａに本体部２ａを挿入したときに本体部２ａを立てた状態で姿勢保持されるようにしている。
【００１６】
このような手すり子２は、下板９ｂのビス固定孔を貫通するビスにより取付台９を踏板１ａ上面端部の適切な位置にビス固定し、本体部２ａの下端開口部を保持部９ａに挿入して取付台９上に本体部２ａを立設し、これを階段１の所定段数の間隔を隔てて踏板１ａ上の同じ位置で行うことにより連設されている。この場合、踏板１ａ上面端部の適切な位置とは、取付台９上に立設された状態での本体部２ａ後面がちょうどその上段の踏板１ａ前面に当接する位置を含む。
【００１７】
本体部２ａの上端開口部には蓋板１２が溶接などにより固着され、蓋板１２上面に手すり支持部材１０を階段１の傾斜角度に合わせて角度変更自在に取り付ける取付部１３が設けられている。取付部１３は、横孔１４を有し蓋板１２上面に併設された２枚の略半円板から形成されている。また、手すり支持部材１０は、木質材料からなる丸棒状の手すり３を下方より係合支持する半円筒状の支持片１０ａと、この支持片１０ａの凸側面の中央部に垂下され横孔１４を有する取付片１０ｂとから形成されている。この支持片１０ａの両端部にはそれぞれビス孔がそれぞれ設けられており、手すり３を支持片１０ａの凹面側に係合した状態で支持片１０ａの凸側より両ビスのビス脚部をクロスするよう各ビス孔に貫通させ手すり３側面にねじ込むことにより、手すり３を手すり支持部材１０に固着するようにしている。そして、取付部１３の両半円板間に手すり支持部材１０の取付片１０ｂを挿入し、取付部１３及び取付片１０ｂの各横孔１０ｃ，１４を連通させてボルト１５・ナット締めにより貫通固定することにより、手すり支持部材１０が階段１の傾斜角度に合わせて前後方向に回動して角度変更自在となるようにしている。また、手すり子２の横桟取り付け位置には角孔状の前後方向の貫通孔６が横桟４の数に合わせて上下方向に並設されている。また手すり子２の貫通孔位置の一側面にはネジ材１６からなる支持軸５が貫通する軸孔１１が設けられ、この支持軸５脚部が螺合するナット材が手すり子２の貫通孔６位置の対向側面の内側に設けられている。また手すり子２下部の前後方向には手すり子２を階段１の踏板１ａ前面にビス固定する固定ビス１７が貫通する前後方向の固定ビス孔１８が上下方向に複数設けられている。
【００１８】
支持軸５は、ネジ材１６から形成されており、支持軸５脚部が軸孔１１を貫通し、貫通孔６の中央部を側方から横切るように進入し、対応するナット材に螺合している。
【００１９】
取付部材７は、縦長の金属製の略角パイプとして形成された横桟４と同部材で形成された角材部７ａと、この角材部７ａの前後端面にそれぞれ延設された固定部７ｂとを有している。角材部７ａは、中央部の横方向に支持軸５の脚部が貫通する軸貫通孔７ｃが設けられており、手すり子２の軸孔１１を貫通する支持軸５脚部がこの角材部７ａの軸貫通孔７ｃを貫通した状態で、取付部材７が貫通孔６内で前後方向に回動可能とされている。固定部７ｂは横桟４の内部開口形状と略同形状の外形を有し、固定部７ｂを横桟４の端部開口部に挿入固定して横桟４が取付部材７に取り付けられている。
【００２０】
このような手すりの取付構造は、以下のようにして行われる。まず階段１の寸法、傾斜角度や隣接する手すり子２間の適切な間隔などから手すり子２を取り付ける階段１の踏板１ａを選択する。次に選択された踏板１ａ上面の階段１側壁と反対側端部の奥側に取付台９をビス固定する。次に本体部２ａの下端開口部を保持部９ａに挿入して本体部２ａを取付台９上に立設する。次に手すり子２の取付部１３に手すり支持部材１０をボルト１５・ナットにより取り付け、複数の手すり支持部材１０に跨って手すり３を載せ、手すり支持部材１０の角度を適切に調整し、ビス固定により手すり３を手すり支持部材１０に固着する。次に手すり子２の後面を踏板１ａ前面に当接させた状態で、手すり子２の固定ビス孔１８に前方よりビス脚部を貫通させ、踏板１ａ前面にねじ込むことで手すり子２を強固に踏板１ａに固定する。次に、手すり子２の貫通孔６に取付部材７を挿入し、軸孔１１と軸貫通孔７ｃを連通させた状態で支持軸５を両孔に貫通させナット材に固定して取付部材７を手すり子２に取り付ける。このようにして取着された取付部材７に適切な長さに切断された横桟４を取り付け、上段又は下段から順次取付部材７の取り付けと横桟４の取り付けを行って、横桟４を手すり子２間に架設していくのである。
【００２１】
なお、手すり子２のうち一番下段及び一番上段に配置されるものにおいては、貫通孔６を手すり子２の前後面の片側にだけ設けるようにしてもよい。例えば一番上段側の手すり子２では貫通孔６を手すり子２前面にのみ設け、一番下段側の手すり子２では貫通孔６を手すり子２後面にのみ設けるようにする。そして、対応する取付部材８も貫通孔６がある方向にだけ横桟４の保持部９ａを設けるようにする。これにより一番下段に配置される手すり子２を前方から見ると貫通孔６や取付部材８が見えず、一番上段に配置される手すり子２を後方から見ると貫通孔６や取付部材８が見えないようにでき、外観を向上させることができる。
【００２２】
このような手すりの取付構造は、手すり子２の側面視横幅中心に横桟４を回動自在に支持する支持軸５を設けているので、手すり３、隣接する手すり子２、横桟４で形成される４角形が平行四辺形となり、階段１の傾斜角度が異なってもその傾斜角度に合わせて平行四辺形の角度が異なるだけであり、手すり３と横桟４との平行関係は保持される。
【００２３】
例えば図３に示すように、手すり３の軸心と隣接する手すり支持部材１０の軸心との交点をＡとし、取付部１３と手すり支持部材１０との固定軸中心点をＢとし、支持軸５の中心点をＣとすると、四角形Ａ−Ａ−Ｂ−Ｂは略長方形であり、線Ａ−Ａと線Ｂ−Ｂとは常に略平行に保持される。また、点Ｂと点Ｃは鉛直方向に線上に位置しているため、四角形Ｂ−Ｂ−Ｃ−Ｃは略平行四辺形であり、線Ｂ−Ｂと線Ｃ−Ｃとは常に略平行に保持される。これにより線Ａ−Ａと線Ｃ−Ｃとは常に略平行状態が保持されることになる。これは階段１の高さが変わって傾斜角度が異なっても四角形Ｂ−Ｂ−Ｃ−Ｃが略平行四辺形である限り、平行状態が維持される。
【００２４】
したがって、傾斜角度の異なる他の階段１に適用しても、手すり子２への横桟４の取付位置を変更することなく、手すり３と横桟４が平行にできる手すりの取付構造が実現できるのである。
【００２５】
また、手すり子２の貫通孔６に支持軸５により回動自在に設けた取付部材７に横桟４を取り付けているので、階段１の傾斜角度が異なって隣接する手すり子２間の横桟４長さが異なっても、横桟４長さを適切な長さに切断調整して取付部材７に取り付けることにより、簡単に横桟４を支持軸５により回動自在とすることができる。また、横桟４が管状部材から形成されているので、横桟４を任意の場所で切断しても横桟４の端部開口部を取付部材７の固定部７ｂに挿入固定することにより、簡単に横桟４を取付部材７に取り付けることができる。
【００２６】
【発明の効果】
本願発明では、手すり子の側面視横幅中心に横桟を回動自在に支持する支持軸を設けているので、手すり、隣接する手すり子、横桟で形成される４角形が平行四辺形となり、階段の傾斜角度が異なってもその傾斜角度に合わせて平行四辺形の角度が異なるだけであり、手すりと横桟との平行関係は保持される。したがって、傾斜角度の異なる他の階段に適用しても、手すり子への横桟の取付位置を変更することなく、手すりと横桟が平行にできる手すりの取付構造が実現できるのである。
【００２７】
また本願発明では、手すり子の貫通孔に支持軸により回動自在に設けた取付部材に横桟を取り付けているので、階段の傾斜角度が異なって隣接する手すり子間の横桟長さが異なっても、横桟長さを適切な長さに切断調整して取付部材に取り付けることにより、簡単に横桟を支持軸により回動自在とすることができる。
【００２８】
また本願発明では、横桟が管状部材から形成されているので、横桟を任意の場所で切断しても横桟の端部開口部を取付部材の固定部に挿入固定することにより、簡単に横桟を取付部材に取り付けることができる。

For example, as shown in FIG. 3, the intersection of the axis of the handrail 3 and the axis of the adjacent handrail support member 10 is A, the fixed axis center point of the mounting portion 13 and the handrail support member 10 is B, and the support shaft If the center point of 5 is C, the quadrangle AABB is substantially rectangular, and the line AA and the line BB are always held substantially parallel. Further, since the points B and C are positioned on the line in the vertical direction, the quadrangle BBC is a substantially parallelogram, and the line BB and the line CC are always substantially parallel. Retained. As a result, the line AA and the line CC are always kept substantially parallel. Even if the height of the staircase 1 is changed and the inclination angle is different, the parallel state is maintained as long as the quadrangle BBCC is a substantially parallelogram.
[0024]
Therefore, even when applied to other stairs 1 having different inclination angles, a handrail mounting structure in which the handrail 3 and the horizontal rail 4 can be parallel without changing the mounting position of the horizontal rail 4 to the handrail 2 can be realized. It is.
[0025]
In addition, since the horizontal beam 4 is attached to the attachment member 7 that is rotatably provided by the support shaft 5 in the through hole 6 of the handrail 2, the horizontal beam between the adjacent handrails 2 with different inclination angles of the stairs 1. Even if the four lengths are different, the horizontal beam 4 can be easily rotated by the support shaft 5 by cutting and adjusting the length of the horizontal beam 4 to an appropriate length and attaching it to the attachment member 7. Further, since the horizontal beam 4 is formed from a tubular member, even if the horizontal beam 4 is cut at an arbitrary place, the end opening of the horizontal beam 4 is inserted and fixed to the fixing portion 7b of the mounting member 7, The crosspiece 4 can be easily attached to the attachment member 7.

【The invention's effect】
In the present invention, since the support shaft that rotatably supports the horizontal beam is provided at the lateral width center of the handrail, the quadrangle formed by the handrail, the adjacent handrail, and the horizontal beam becomes a parallelogram, Even if the inclination angle of the stairs is different, only the angle of the parallelogram is changed in accordance with the inclination angle, and the parallel relationship between the handrail and the horizontal rail is maintained. Therefore, even when applied to other stairs with different inclination angles, it is possible to realize a handrail mounting structure in which the handrail and the horizontal rail can be parallel without changing the mounting position of the horizontal rail to the handrail.
[0027]
Further, in the present invention, since the horizontal beam is attached to the attachment member that is rotatably provided by the support shaft in the through hole of the balustrade, the horizontal beam length between the adjacent balustrades is different because the inclination angle of the stairs is different. However, by cutting and adjusting the length of the horizontal beam to an appropriate length and attaching it to the attachment member, the horizontal beam can be easily rotated by the support shaft.
[0028]
Further, in the present invention, since the horizontal beam is formed of a tubular member, even if the horizontal beam is cut at an arbitrary position, the end opening of the horizontal beam is inserted and fixed to the fixing part of the mounting member, so that The crosspiece can be attached to the attachment member.
