ANTECEDENT HANDRAIL
To provide an antecedent handrail that can easily perform work when constructing it between two support pillars.SOLUTION: An arcuate long hole 12 having a revolving center axis of an engaging member as a center in the front view is formed closer to a longitudinal direction central part side of a handrail main body 5 than the revolving center axis of the engaging member 7, in an upper portion of the engaging member 7 of an antecedent handrail 4. A positioning pin 9 extending to a forward and backward direction, inserting the long hole 12 and capable of moving to a longitudinal direction of the long hole 12 is provided on the handrail main body 5. A positioning notch 13 fitting the positioning pin 9 is formed on one arcuate edge 121 of the long hole 12. A compression coil spring 11 energizing the positioning pin 9 fitted into the positioning notch 13 to a depth side of the positioning notch 13 is provided on the handrail main body 5. The positioning pin 9 is fitted within the positioning notch 13 in an installation state that an insertion part 71 of the engaging member 7 and the handrail main body 5 form a right angle.SELECTED DRAWING: Figure 3
【課題】２つの支柱間に架設する際の作業を容易に行うことができる先行手摺をを提供する。【解決手段】先行手摺４の係合部材７の上部に、前方から見て係合部材の回動中心軸線を中心とする円弧状の長穴12を、係合部材7の回動中心軸線よりも手摺本体５の長手方向中央部側に形成する。手摺本体５に、前後方向に延びるとともに長穴12に挿通されて当該長穴12の長手方向に移動しうる位置決めピン９を設ける。長穴12の一方の円弧状縁121に、位置決めピン９が嵌まる位置決め用切り欠き13を形成する。手摺本体５に、位置決め用切り欠き13内に嵌まった位置決めピン９を位置決め用切り欠き13の奥側に付勢する圧縮コイルばね11を設ける。係合部材７の挿入部71と手摺本体５とが直角をなした設置形態で位置決めピン９が位置決め用切り欠き13内に嵌まる。【選択図】図３
