PLATFORM FENCE
To provide a method by which structure and management of a platform fence is simplified without loss of safety on a platform.SOLUTION: In a platform fence, a closed attitude changes into an open attitude by making a first arm 11 and a second arm 21 pivot toward a lateral direction or toward an upper direction. A first passage blocking member 40 and a second passage blocking member 41 are installed from a tip of the first arm 11 to a tip of the second arm 21. When the fence is in a closed attitude, a distance between the first passage blocking member 40 and the second passage blocking member 41 in a vertical direction is increased. When the fence is in an open attitude, a distance between the first passage blocking member 40 and the second passage blocking member 41 in a vertical direction is narrowed.SELECTED DRAWING: Figure 1
【課題】プラットホーム上の安全性を損なわせることなく、プラットホーム柵の構造及び制御をシンプルにする。【解決手段】第１アーム１１及び第２アーム２１を横方向又は上方向に揺動させることにより、閉姿勢と開姿勢に切り替える。第１アーム１１の先端部から第２アーム２１の先端部まで第１通行遮断部材４０及び第２通行遮断部材４１を設ける。閉姿勢にあるときには、第１通行遮断部材４０及び第２通行遮断部材４１の上下方向の間隔を広げる。開姿勢にあるときには、第１通行遮断部材４０及び第２通行遮断部材４１の上下方向の間隔を狭める。【選択図】図１
