PROBLEM TO BE SOLVED: To provide a platform fence which can elevate plural movable bars with a simple structure and can be installed even at a place where a ceiling is low.SOLUTION: A platform fence 1 comprising a left column 10L and a right column 10R, and a movable fence 20 which is supported by the left column 10L and the right column 10R limits or permits passing by vertically moving the movable fence 20. The movable fence 20 has: an upper movable bar 20b; a holding member which so holds the upper movable bar 20b as to be vertically movable within a constant height range; and a lower movable bar 20c which is elevated by a first driving member between a lower limit position lower than the constant height range and an upper limit position involved in the constant height range. When the movable fence 20 limits passing, the lower movable bar 20c is lowered to the lower limit position by the first driving member and is separated from the upper movable bar 20b. When the movable fence 20 permits passing, the lower movable bar 20c is elevated to the upper limit position by the first driving member, and is brought into contact with the upper movable bar 20b.SELECTED DRAWING: Figure 1

    【課題】複数の可動バーを簡易な構造で昇降するとともに天井の低い場所でも設置することができるホーム柵を提供する。【解決手段】ホーム柵1は、左柱10Lおよび右柱10Rと、左柱10Lおよび右柱10Rに支持される可動柵20とを備え、可動柵20を上下方向へ可動して通行を制限または許可する。可動柵20は、上側可動バー20bと、上側可動バー20bを一定の高さ範囲内で上下動作可能に保持する保持部材と、第1の駆動部材によって、その一定の高さ範囲よりも下側の下限位置とその一定の高さ範囲に含まれる上限位置との間を昇降する下側可動バー20cと、を有する。可動柵20が通行を制限する場合、下側可動バー20cが第1の駆動部材によって下限位置へ下降して上側可動バー20bと離れ、可動柵20が通行を許可する場合、下側可動バー20cが第1の駆動部材によって上限位置へ上昇し、上側可動バー20bと当接する。【選択図】図1
