Description

【０００１】
【発明の属する技術分野】
本発明は、住宅などのバルコニー・ベランダ等に取り付ける手摺の構造に関し、より詳しくは、手摺の支持具の構造に関する。
【０００２】
【従来の技術】
住宅などのバルコニーやベランダ等の周縁部には、転落防止等を目的として外壁を立設し、外壁の上方に手摺を配設している。この手摺は外壁に支持具を介して固定されており、該支持具は下部に形成された固定部により外壁に固定されるとともに、上部に設けられた載置部に手摺を支持する構成としている。従来の支持具の固定部は、図１１に示すように、断面視略コ字状の本体１０２及び蓋体１０３等より構成されている。そして、前記固定部の取り付けにおいては、前記外壁から取付部１１０を突出して、該取付部１１０に取付孔１１０ａ・１１０ａを開口し、該取付孔１１０ａ・１１０ａと前記支持具の本体１０２に形成されている取付孔１０２ａ・１０２ａとの位置を合わせる。そして、前記本体１０２の外側面に設けられた溝１０２ｂ・１０２ｂからボルト１０５・１０５を嵌入し、前記取付孔１１０ａ・１１０ａ・１０２ａ・１０２ａに挿通して、ナット１０４・１０４で締結固定し、取付部１１０に本体１０２を固定していた。そして、取付部１１０に対して本体１０２と反対側に蓋体１０３を装着し、下方からネジ１０６等で蓋体１０３を固定していた。
【０００３】
【発明が解決しようとする課題】
しかし、従来の支持具の固定部は、複数の部材から構成されており、また、支持具の取り付けには複数の締結部材を必要とするため、運搬時・作業時に部品を紛失したり、忘れたりし易いという問題があった。また、支持具を取り付ける際、本体を支えながら支持具と取付部とを、ボルト・ナットで締結しなければならず、また、本体と蓋体との取り付けにおいては下方からネジを挿入し取り付けなければならず、取付作業が行ない難く、作業が煩雑であるという不具合もあった。そこで、本発明では、部品点数が少なく、また、取付作業が行ない易い手摺の支持具を提供する。
【０００４】
【課題を解決するための手段】
本発明の解決しようとする課題は以上の如くであり、次にこの課題を解決するための手段を説明する。
【０００５】
バルコニー（１）の周縁部に立設される外壁（６）の上方に手摺を設けるための支持具（２）であって、該支持具（２）を、手摺（７）を載置固定する載置部（４）と、前記外壁に固定する固定部（３）と、連結部（５）より構成し、前記固定部（３）は一面を開放した箱体にて一体的に構成し、前記外壁（６）内面に、内側に向けてプレート状の取付部（６１）を突出し、該取付部（６１）に前記支持具（２）を固定する為の孔（６１ａ）を水平方向に開口し、該箱体に構成した固定部（３）の凹部（３１）内には、左右内側壁から内部に向けて支持部（３２ａ・３２ｂ）を突設し、該一方の支持部（３２ａ）にナット（３４）を嵌入して回り止め可能とする溝部（３３）を形成し、該他方の支持部（３２ｂ）の中央には、左右水平方向に貫通する取付孔（３５）を形成し、該取付孔（３５）は前記取付部（６１）を装着した際、該取付部（６１）に設けられた孔（６１ａ）と同軸心上となる位置に設け、該取付孔（３５）は二段の円筒形状の孔で、大径の孔が外側に位置し、ボルト（３６）の頭部を支持し、該左右の支持部（３２ａ・３２ｂ）間の距離は、前記取付部（６１）の厚みより大きく形成し、また、前記取付部（６１）を支持部（３２ａ・３２ｂ）間に嵌入した時に、該取付部（６１）と支持部（３２ａ・３２ｂ）との隙間は、ナット（３４）の厚みより小さくなるように構成し、前記溝部（３３）にナット（３４）を嵌入し、接着部材で仮止め固定し、該ナット（３４）に前記ボルト（３６）を螺装し、操作具によりボルト（３６）を締め付けると、前記仮止め固定が外れてナット（３４）が前記溝部（３３）内で軸方向に移動するが、該ナット（３４）が前記溝部（３３）から外れない構成としたものである。
【０００６】
【発明の実施の形態】
次に、発明の実施の形態を説明する。
【０００７】
図１は本発明の支持具の使用例を示す図、図２は支持具の側面図、図３は固定部の右側面図、図４は同じく左側面図、図５は同じく正面図、図６はＡ−Ａ矢視断面図、図７はＢ−Ｂ矢視断面図である。
【０００８】
図８は固定部の取付を示す図、図９は固定部の取付部への嵌入を示す図、図１０は固定部の締付を示す図、図１１は従来の支持具における固定部の断面図である。
【０００９】
本発明の支持具は、バルコニー・ベランダ等の手摺と外壁との間に介設し、手摺を外壁に固定するものである。図１に示すように、住宅におけるバルコニー１において、居室側と接する部位以外のバルコニー１の周縁部に、コンクリート又は、アルミやステンレスからなる外壁６を立設し、転落等を防止している。
【００１０】
この外壁６内面の上部に、水平内側に向けてプレート状の取付部６１・６１・・・を突出して配設しており、該取付部６１・６１・・・に、本発明の支持具２・２・・・の下部を固定するとともに、該支持具２・２・・・の上面に、断面視円筒形状の手摺７を載置固定することで、外壁６に手摺７を固定している。また、前記取付部６１・６１には、支持具２を固定するための孔６１ａ・６１ａ（図９）が水平方向に開口されている。
【００１１】
次に、支持具２について説明する。図２に示すように、支持具２は、前記外壁６に固定する固定部３と、前記手摺７を載置固定する載置部４と、固定部３と載置部４とを結ぶ連結部５とで構成されている。該連結部５は、側面視く字状に形成されており、下部が上下方向に延設されて下端部に固定部３が、上端には載置部４が一体的に形成されている。そして、連結部５は、支持具２を外壁に取り付けたとき、載置部４が固定部３より外側に配置し、手摺７が外壁６の上方に位置するようにしている。
【００１２】
また、前記載置部４は、上面が手摺７の外径に合わせた曲面４１に形成しており、前記手摺７を載置すると、手摺と嵌合するように形成されている。また、載置部４に取付孔４２・４２を穿設しており、載置部４と手摺７をネジ１１・１１等の固定手段で固定できるようにしている。なお、本実施例では、固定部３、載置部４及び連結部５とを一体成形しているが、溶接等で固定する構成とすることもできる。
【００１３】
次に、固定部３について説明する。図３乃至図１０に示すように、固定部３は、平面断面視及び側面断面視略コ字状に形成されて、一面（前面）を開放した箱体にて一体的に構成されている。つまり、固定部３は一面に凹部３１を形成した直方体に構成されている。該固定部３の後面は閉じた形状で、前記連結部５と連結している。また、該凹部３１は、固定部３を取付部６１に嵌入した時、前記外壁６と固定部３の前面が当接するように形成しており、また、固定部３の上面において、前部を高く後部を低く形成している。このようにすることで、固定部３を外壁６の取付部６１に装着固定した場合、雨水等が後方に流れ、前記凹部３１に入らないようにしている。
【００１４】
前記固定部３の凹部３１内には、支持部３２ａ・３２ａ・３２ｂ・３２ｂが設けられており、該支持部３２ａ・３２ａ・３２ｂ・３２ｂは、固定部３の左右内側壁から内部に向けて突設している。該支持部３２ａ・３２ａ・３２ｂ・３２ｂは、左右一対として上下に設けられており、左右対称に配置されている。そして、左右の支持部３２ａ・３２ｂ間の距離は、外壁６の取付部６１の厚みより若干大きくなるように形成し、支持部３２ａ・３２ｂ間に前記取付部６１を嵌入しやすくしている。また、前記取付部６１を支持部３２ａ・３２ｂ間に嵌入した時、取付部６１と支持部３２ａ・３２ｂ間との隙間は、後述するナット３４の厚みより小さくなるようにしている。また、前記支持部３２ａ・３２ａ・３２ｂ・３２ｂは、固定部３と一体的に構成されており、例えば一体成形により作製されている。なお、支持部の個数は、固定部３の左右一側に配設される支持部の個数が前記取付部６１の孔６１ａと同数であれば、限定するものではない。
【００１５】
図６に示すように、固定部３の一側の側面（本実施例では右側側面）内部に配設されている支持部３２ｂ・３２ｂの中央には、左右水平方向に貫通する取付孔３５・３５を形成している。この取付孔３５・３５は、図８に示すように前記取付部６１に装着した際、該取付部６１に設けられた孔６１ａ・６１ａと同軸心上に位置するように配置している。この取付孔３５は、二段の円筒形状の孔で、大径の孔が外側に位置しており、後述するボルト３６の頭部を支持し、また、図３に示すように、固定部３の外側面まで貫通して、ボルト３６のネジ部を挿入するようにしている。
【００１６】
一方、図７に示すように、固定部３の他側の側面（本実施例では左側側面）内部に配設されている支持部３２ａ・３２ａには、溝部３３が形成されている。該溝部３３は、ナット３４を嵌入しており、該ナット３４は、前記支持部３２ｂの取付孔３５・３５と同軸心上に位置するように配設されている。前記溝部３３は、ナットが回動不能となるように形成されている。つまり、溝部３３の上下高さをナット３４の平行部分の外形より若干大きく形成し、ナット３４が溝部３３の上下方に配置する支持部３２ａに当接して回動しないようにしている。溝部３３の後部は、前記ナット３４の後部と略同形状としており、前部は開放した形状としている。そして、該溝部３３の後部に、ナット３４を接着剤などの接着部材で着接して、ナット３４を固定部３に仮固定して、ナット３４の紛失を防止し、作業性を向上している。
【００１７】
次に、支持具２の取り付けについて説明する。まず、図９に示すように、前記外壁６から突設している取付部６１に、前記固定部３の凹部３１を嵌入する。このとき、左右に配設している支持部３２ａ・３２ａ・３２ｂ・３２ｂ間の距離を取付部６１の厚みより若干大きくしているので、支持部３２ａ・３２ａ・３２ｂ・３２ｂ間に前記取付部６１が容易に嵌入できる。そして、図８（ａ）、図１０に示すように、取付部６１の孔６１ａ・６１ａと、前記取付孔３５・３５及びナット３４・３４とが同軸心上にくるように、固定部３の位置を調節する。そして、ナット３４の操作具である六角孔付きボルト３６・３６を、外側方から前記取付孔３５・３５に挿入し、固定部３の内部に装着されているナット３４・３４に螺装固定する。図８（ｂ）に示すように、前記ボルト３６・３６をナット３４・３４に螺挿する際、締付力によりナット３４・３４の仮固定が外れ、ナット３４・３４が軸方向に移動可能となる。しかし、ナット３４・３４は、前記溝部３３・３３から外れないため、該ナット３４・３４は、溝部３３・３３により回り止めされる。従って、ボルト３６・３６を回動することで、取付部６１と固定部３が締結される。このようにして、外壁６に支持具２を固定している。また、外壁６から突設している複数の取付部６１・６１・・・に、同様に支持具２・・・を取り付け、最後に複数の支持具２・２・・・の載置部４・４・・・に手摺７を載置し、手摺７と載置部４・４・・・とを固定手段であるネジ１１・・１１・・・で締結固定し、手摺７を外壁６に装着固定する。
【００１８】
以上のように、前記固定部３を一面を開放した箱体にて一体的に構成したので、部品点数を削減でき、低コスト化を図ることができる。また、固定部３にナット３４を嵌入固定する溝部３３を形成し、前記溝部３３にナット３４を嵌入し、接着部材で固定部３に固定したので、ナット３４を溝部３３に嵌入することでナット３４が回動不能となり、ボルト３６で締結する際、ボルト３６の回転と同時にナット３４が回動することがない。従って、ナット３４を支持する必要がなく、片手で支持具２を支えながら、反対の手でボルト３６を締めることができるので、支持具２の取付作業が行いやすくなり、作業効率の向上を図ることができる。更に、ナット３４を予め固定部３に装着しておくことで、運搬時・作業時の部品点数を削減することができ、また、ナットを紛失したり、忘れたりすることがない。そして、ボルト３６・３６をナット３４・３４に螺挿する際、ナット３４・３４の仮止めが外れることで、ナット３４・３４により取付部６１・６１を確実に挟持固定でき、また、仮止めが外れてもナット３４・３４は、溝部３３・３３から外れないので、ナット３４・３４が溝部３３・３３に回り止めされ、ボルト３６・３６による締結が確実に行なえる。なお、取付部６１は本実施例では壁より側方に突出しているが、上方に突出して、固定部３は下方に開口するように構成することもできる。
【００１９】
【発明の効果】
本発明は、以上のように構成したので、以下に示すような効果を奏する。
【００２０】
バルコニー（１）の周縁部に立設される外壁（６）の上方に手摺を設けるための支持具（２）であって、該支持具（２）を、手摺（７）を載置固定する載置部（４）と、前記外壁に固定する固定部（３）と、連結部（５）より構成し、前記固定部（３）は一面を開放した箱体にて一体的に構成し、前記外壁（６）内面に、内側に向けてプレート状の取付部（６１）を突出し、該取付部（６１）に前記支持具（２）を固定する為の孔（６１ａ）を水平方向に開口し、該箱体に構成した固定部（３）の凹部（３１）内には、左右内側壁から内部に向けて支持部（３２ａ・３２ｂ）を突設し、該一方の支持部（３２ａ）にナット（３４）を嵌入して回り止め可能とする溝部（３３）を形成し、該他方の支持部（３２ｂ）の中央には、左右水平方向に貫通する取付孔（３５）を形成し、該取付孔（３５）は前記取付部（６１）を装着した際、該取付部（６１）に設けられた孔（６１ａ）と同軸心上となる位置に設け、該取付孔（３５）は二段の円筒形状の孔で、大径の孔が外側に位置し、ボルト（３６）の頭部を支持し、該左右の支持部（３２ａ・３２ｂ）間の距離は、前記取付部（６１）の厚みより大きく形成し、また、前記取付部（６１）を支持部（３２ａ・３２ｂ）間に嵌入した時に、該取付部（６１）と支持部（３２ａ・３２ｂ）との隙間は、ナット（３４）の厚みより小さくなるように構成し、前記溝部（３３）にナット（３４）を嵌入し、接着部材で仮止め固定し、該ナット（３４）に前記ボルト（３６）を螺装し、操作具によりボルト（３６）を締め付けると、前記仮止め固定が外れてナット（３４）が前記溝部（３３）内で軸方向に移動するが、該ナット（３４）が前記溝部（３３）から外れない構成としたので、部品点数を削減でき、コストの低減化を図ることができる。
【００２１】
また、前記固定部の内側面の一側に、ナットを嵌入して回り止め可能とする溝を形成したので、ナットを溝部に嵌入することでナットが回動不能となり、固定手段で締結する際、固定手段の回転と同時にナットが回動しない。従って、ナットを支持する必要がなく、片手で支持具を支えながら、反対の手でネジ等の固定部材を締めることができ、支持具の取付作業が行いやすくなり、作業効率の向上を図ることができる。
【００２２】
また、前記溝にナットを嵌入し、接着部材で固定したので、運搬時・作業時の部品点数を削減することができ、また、ナットを紛失したり、忘れたりすることがない。
【００２３】
また、前記ナットの固定を仮止め固定とし、ナット操作具により締め付けると、前記仮止め固定が外れてナットが軸方向に移動可能となるが、該ナットが前記溝から外れることはないので、ナットが溝に回り止めされ、ナット操作具による締結が確実に行なえる。
