PROBLEM TO BE SOLVED: To provide a technique of a movable fence that can be realized in a low cost without a restriction from stop accuracy of trains or train cars with different door positions.SOLUTION: As shown in the Figure 5(c), when a cylindrical pole 20 reaches a highest part, a movable lock part 71 of the cylindrical pole 20 is locked to a fixed side lock 72 of a pole-housing cylinder part 80 so that further rising becomes impossible. As shown in the Figure 5(d), when an engagement chain 61 is further extended, as the lock prevents further rising of the cylindrical pole 20, a spring 58 becomes compressed gradually. Consequently, the distance between an upper link fix part 23 and a chain fix part 25 is decreased, and by an operation of a link mechanism of a link-style arm fence 40, the link-style arm fence 40 is expanding.

    【課題】列車の停止精度や異なる扉位置の車両に対して、制限を受けることなく低コストで実現可能な可動柵の技術を提供する。【解決手段】図5(c)に示す様に、筒状支柱20が最上部まで到達すると、筒状支柱20の可動側ロック部71が支柱収納円筒部80の固定側ロック72にロックし、それ以上の上昇が出来なくなる。図5(d)に示す様に、さらに噛み合いチェーン61を延出させると、ロックによって筒状支柱20が上昇せずバネ58が徐々に圧縮される。その結果、上側リンク固定部23とチェーン固定部25の距離が縮まり、リンク状アーム柵40のリンク機構の動作によって、リンク状アーム柵40が広がっていく。【選択図】図5
