【発明の属する技術分野】
本発明は、道路などに設置される道路標識や案内標識等における横梁と標識用板材の取付構造に関するものである。
【０００２】
【従来の技術】
道路標識や案内標識等は、道路利用者に対し情報を提供するものであるが、より情報を明瞭に表示し、且つ道路を走行する車両等に衝突するのを回避すべく、道路周辺に立設された支柱や、擁壁等から横梁を突設し、その横梁に表示板などの標識用板材を取り付けた道路標識や案内標識等が用いられてきている。
【０００３】
従来、横梁への標識用板材や支柱の取付構造として最もよく用いられてきているのは、例えば特許文献１に記載の如く、標識用板材の上下方向に設けられた蟻溝状の取付溝を用いて摺動可能になされた一対のＵバンドにより横梁を挟み込んで固定する方法であり、かかる方法によれば標識用板材を上下左右任意の位置に取り付けることが可能であり、また位置の微調整を行うことも容易である。

【発明の実施の形態】
本発明の実施の形態について、図面に基づき以下に具体的に説明する。
図１〜図６は、本発明に係わる実施の一形態を示すもので、図１及び図２は道路標識全体、図３〜図６は横梁受け金具と横梁固定金具との取り付けの詳細を示す説明図である。図１において、本発明に係わる道路標識１００は、表示面Ｈを有する標識用板材１０が支柱３０により支持された上段の横梁２０Ａ及び下段の横梁２０Ｂに取り付けられているものである。
【００１５】
図２は、道路標識１００の、横梁２０Ａ及び２０Ｂに対する標識用板材１０の取付構造を示す側面図である。まずイ）において、上段の横梁２０Ａに、スペーサー５を介して回動軸４により、標識用板材１０が上端付近で標識用板材１０の縁部に沿って軸着される。一方、標識用板材１０の下方には予め横梁受け金具１が、レール３により上下方向に摺動可能に取り付けられている。
【００１６】
ロ）において、標識用板材１０は回転軸４を中心に回動され、表示面Ｈが斜め下方に向けられ、道路利用者からの視認性を高められる。尚、標識用板材１０は回転軸４を用いて軸着せず、表示面Ｈを斜め下方に向けた状態で、Ｕバンド等で固定してもよい。
【００１７】
次にハ）において、下段の横梁２０Ｂに横梁受け金具１がレール３により下方から摺動されて当接され、更に横梁固定金具２が横梁受け金具１に取り付けられ、横梁受け金具１と横梁固定金具２の間に横梁２０Ｂが挟持されて、標識用板材１０は横梁２０Ａ及び２０Ｂに取り付けられる。
【００１８】
図１及び図２に示す横梁受け金具１及び横梁固定金具２の取付構造の一例の詳細を示す説明図が図３〜図６であり、まず図３において、標識用板材１０には上下方向にレール３がスポット溶接Ｓ等で取り付けられることで、蟻溝状の取付溝３１が設けられる。取付溝３１の横梁受け金具１より下方側には、横梁受け金具１が取付溝３１内を摺動して脱落しないよう、ストッパーを設けておいてもよい。
【００１９】
次に図４において、この取付溝３１に、ボルトＢ２の頭部が挿入され、挿入されたボルトＢ２に、横梁受け金具１に穿設された貫通孔１１が挿通され、ナットＮ２を螺着して仮り止めすることで、横梁受け金具１は標識用板材１０の上下方向に摺動可能に取り付けられる。横梁受け金具１は、上方に面した当接面１２において横梁２０に当接されるが、貫通孔１１は当接面１２より下方に設けられており、ナットＮ２の螺着によるボルト止めは当接面１２より下方で可能となされている。
【００２０】
更に図５において、横梁受け金具１が取付溝３１により摺動されて、横梁２０（図示せず）に当接面１２が当接された状態でナットＮ２が本締めされて固定され、次に横梁固定金具２がその内面２１に横梁２０（図示せず）が当接され、横梁受け金具１と横梁固定金具２とで横梁２０（図示せず）を挟持するように取り付けられる。

【００２２】
かかる取付構造により、取付溝３１に固定された横梁受け金具１に対し横梁固定金具２を取り付けて横梁２０を挟持できることで、安定した状態で横梁固定金具２を横梁受け金具１に取り付けることができ、作業は簡潔で、且つ安全性の高いものとなり得る。更に、予め標識用板材１０に横梁受け金具１を摺動可能に仮り止めしておけば、上段の横梁２０Ａ及び下段の横梁２０Ｂの間隔に関わらず取付構造が適用できると共に、横梁２０Ｂ付近で取り付けを行う部材は横梁固定金具２だけで済み、部材を高所まで運搬する手間や、高所における部材の支持に要する労力を軽減できる。
【００２３】
また、標識用板材１０が上端付近で標識用板材１０の縁部に沿って横梁２０Ａに軸着され、且つ横梁受け金具１が下方から横梁２０Ｂに当接されて横梁固定金具２が取り付けられることで、表示面Ｈを下方に傾斜させる角度を任意に設定することができる。また、回転軸４と横梁受け金具１とで標識用板材１０に張力が生じた状態で横梁固定金具２の取り付けが行え、横梁固定金具２の取り付け時の安定感を高めることができる。更に、上方の回転軸４と、下方の横梁受け金具１及び横梁固定金具２との２点で標識用板材１０は支持され、取り付け後の風荷重等に対する強度が高められる。
【００２４】
更に、横梁受け金具１及び横梁固定金具２の取り付けに係わる全てのボルト止めが当接面１２より下方から可能となされており、ボルト止めの際に横梁２０が障害となることがなく、また取り付けに係わるスペースが小さい場合でもボルト止めは容易なものとなり得る。

図８は、標識用板材１０Ｂの取付部の詳細を示す説明図であり、標識用板材１０Ａには取付部材６が設けられ、回転軸４が設けられた取付部材７に標識用板材１０Ｂが取り付けられている。取付部材７には雪割板Ｙの一端が櫛の歯状部Ｋに挿入されることで角度変更可能となされ、常に垂直に取り付けることが可能である。取付部材７に設けられた回転軸４が、取付部材６の一部に嵌入されて軸着されることで、標識用板材１０Ｂは上端付近で、標識用板材１０Ｂの縁部に沿って標識用板材１０に軸着され、その傾斜角度は自在に設定可能となる。かかる標識用板材１０Ｂは、既に設置されている道路標識等に対しても、取付部材６を取り付けるのみで後付け可能なものである。
【００２７】
図９は、標識用板材１０Ｂの取り付けを示す側面図で、まずイ）において、表示面Ｈを有する標識用板材１０Ａは横梁２０Ａ及び２０Ｂに、スペーサー５により表示面Ｈが下方に傾斜されて固定されている。標識用板材１０Ａの固定方法は公知のものでよく、図１〜図６に示す如きものでもよい。更に下方にレール３に横梁受け金具１が摺動可能に予め取り付けられた標識用板材１０Ｂが、取付部材７に設けられた回転軸４を、標識用板材１０Ａに取り付けられた取付部材６に嵌入して軸着することで標識用板材１０Ａに取り付けられる。
【００２８】
次にロ）において、標識用板材１０Ｂが回転軸４を中心に回動され、横梁２０Ａに標識用板材１０Ｂの内面又はレール３が当接される。かかる構造は、横梁２０Ａの位置が一定でなくとも標識用板材１０Ｂは取付可能であり、横梁２０Ａがあらゆる位置に設けられた道路標識等に対し適用できるものである。最後にハ）において、横梁受け金具１がレール３により摺動されて、下方から横梁２０Ａに当接され、横梁受け金具１に横梁固定金具２が、横梁２０Ａを挟持するように取り付けられて、標識用板材１０Ｂは横梁２０Ａに取り付けられる。
【００２９】
かかる取付構造により、前述の如く、安定した状態で横梁固定金具２を横梁受け金具１に取り付けることができ、作業は簡潔で、且つ安全性の高いものとなり得ると共に、部材を高所まで運搬する手間や、高所における部材の支持に要する労力を軽減できる。
【００３０】
更に、横梁受け金具１と横梁固定金具２の取り付けにおいて、図３〜図６に示した実施形態の如く、当接面１２より下方で全てのボルト止めが可能となされていれば、２枚の標識用板材１０Ａ、１０Ｂ間のスペースが小さいものであっても、比較的広く開かれた下方のみからボルト止めを行うことができ、本発明により得られる効果は更に大きなものとなる。
【００３１】
本発明に係わる取付構造を備えた道路標識や標識雪庇防止板は、部材を高所まで運搬する手間や、高所に於ける部材の支持に要する労力を軽減でき、且つ取り付けに係わるスペースが狭いものであっても一方向からの取り付けが可能なものであり、取り付けに係わる安全性や容易性を具備したものとなり得る。
【００３２】
【発明の効果】
本発明によれば、取付溝に固定された横梁受け金具に対し横梁固定金具を取り付けて横梁を挟持できることで、安定した状態で横梁固定金具を横梁受け金具に取り付けることができ、作業は簡潔で、且つ安全性の高いものとなり得る。更に、予め標識用板材に横梁受け金具を摺動可能に仮り止めしておけば、上段の横梁及び下段の横梁の間隔に関わらず取付構造が適用できると共に、横梁付近で取り付けを行う部材は横梁固定金具だけで済み、部材を高所まで運搬する手間や、高所における部材の支持に要する労力を軽減できる。

[0030]
Further, in attaching the cross beam receiving metal fitting 1 and the cross beam fixing metal fitting 2, if all bolts can be fixed below the contact surface 12 as in the embodiment shown in FIGS. Even if the space between the marking plates 10A and 10B is small, bolting can be performed only from the lower side opened relatively widely, and the effect obtained by the present invention is further increased.
[0031]
The road sign and the sign snowfall prevention plate provided with the mounting structure according to the present invention can reduce the labor required to transport the member to a high place and the labor required to support the member at a high place, and the space for mounting is narrow. Even if it is a thing, the attachment from one direction is possible and it can have the safety | security and ease regarding attachment.
[0032]
【The invention's effect】
According to the present invention, the horizontal beam fixing bracket can be attached to the horizontal beam receiving bracket fixed to the mounting groove to sandwich the horizontal beam, so that the horizontal beam fixing bracket can be attached to the horizontal beam receiving bracket in a stable state, and the operation is simple. And it can be highly safe. In addition, if the horizontal beam support bracket is temporarily slidably secured to the sign plate, the mounting structure can be applied regardless of the distance between the upper horizontal beam and the lower horizontal beam, and the member to be mounted near the horizontal beam is a horizontal beam. Only the fixing brackets are required, and it is possible to reduce the labor required to carry the member to a high place and the labor required to support the member at a high place.
