ROAD SIGN POLE
PROBLEM TO BE SOLVED: To provide a road sign pole which improves workability of detachment immediately before a snowfall season and attachment after a snowfall season.SOLUTION: A road sign pole 1 includes: a sign pole body 2; a pedestal part 3 installed on a lower part of the sign pole body 2; a mounting shaft 5 protruding downward from the pedestal 3; an embedding leg 4 embedded in a road surface GL and to which the mounting shaft 5 is attached and fixed. A key 6 protruding in a direction orthogonal to the axial direction is installed on the mounting shaft 5. The embedding leg 4 is comprised of a cylindrical pipe part and a cover part fixed to the upper part of the pipe part. A bearing hole having a diameter larger than the shaft diameter of the mounting shaft 5 is provided in the central part of the cover part. A key groove is provided in at least one place around the bearing hole, through which the key 6 of the mounting shaft 5 is inserted. A stop pin protruding from the rear face toward the inside of the pipe part is formed on the rear face of the cover part. At least one stop pin is formed at a position apart from the key groove. The key 6 abuts on the stop pin to stop the rotation of the mounting shaft 5.SELECTED DRAWING: Figure 2
【課題】降雪期直前の取り外しの作業性や、降雪期を過ぎた後の取り付けの作業性が向上する道路標識柱を提供すること。【解決手段】標識柱本体2と、標識柱本体2の下部に設けられる台座部3と、台座部3から下方に突出する取付軸5と、路面GLに埋設され、取付軸5を装着して固定する埋設用脚4とを有する道路標識柱1において、取付軸5には、軸方向と直行する方向に突出するキー6が設けられ、埋設用脚4は、円筒状のパイプ部と、パイプ部の上部に固定された蓋部からなり、蓋部の中央部には、取付軸5の軸径よりも大径な支持孔が設けられ、支持孔の周囲の少なくとも１か所には、取付軸5のキー6が挿通されるキー溝が設けられ、蓋部の裏面には、裏面からパイプ部の内部に向かって突出するストップピンが形成され、ストップピンは、キー溝から離れた位置に、少なくとも１個形成されており、キー6がストップピンに当接して、取付軸5の回転を停止させることを特徴とする。【選択図】図２
