To provide a technology which makes a bottom shutdown part of an elevation type platform fence as low as possible during full closing.SOLUTION: A platform fence 2 which moves N (N≥3) shutdown parts 6 built across support rods 4 vertically for opening or closing comprises stationary pillar sections 10 and an elevation part 20 vertically moving against the stationary pillar sections. The elevation part 20 is a mechanism part that is a linear connection of a plurality of links 31 and comprises an expansion link mechanism part 30 for every other joint part 32 to support the shutdown part 6 one by one, an upper fixing part 40 fixing the upper part of the expansion link mechanism part at a prescribed position, a vertical guidance part 50 guiding a vertical movement of the every other joint part 32, a pulley 60 fixed at a prescribed upper position and a linking belt 62 with one end fixed to the stationary pillar section 10 and the other end connected to the lower part of the expansion link mechanism part 30 via the pulley 60.SELECTED DRAWING: Figure 3

    【課題】昇降式のホーム柵において、全閉時の最下段の遮断部をできるだけ低くすることを可能とする技術を提供すること。【解決手段】支柱4間に渡されたN本(N≧3)の遮断部6を上下させて開閉する昇降式のホーム柵2であって、固定柱部10と、当該固定柱部に対して上下動する昇降部20と、を備える。昇降部20は、複数のリンク31を線状に連結した機構部であって、遮断部6を1つおきのジョイント部32が1本ずつ支持する伸縮リンク機構部30と、当該伸縮リンク機構部の上部を所定位置で固定する上部固定部40と、1つおきのジョイント部32の上下方向への移動を案内する上下案内部50と、所定の上方位置に固定されたプーリ60と、一端が固定柱部10に対して固定され、プーリ60を介して他端が伸縮リンク機構部30の下部に接続されたリンク用ベルト62と、を有する。【選択図】図3
