PROBLEM TO BE SOLVED: To provide a novel platform fence having a mechanical locking mechanism.SOLUTION: A platform fence comprises a door storage part 6 on a track side surface having a driving pulley 103 and a driven pulley 104 provided in a traveling direction of a door part 4, and in which an annular rope-like member 105 is stretched between both pulleys. An operation part 110 projectingly provided with a roller 111 is fixed to the rope-like member 105 at a position offset toward a platform side. The roller 111 is engaged with an engaging part 120 disposed on the track side surface of the door part 4. The operation part 110 is positioned just besides the driven pulley 104 in a fully closed state. When an external force to open the door part 4 is applied in the fully closed state, the force is transmitted through the roller 111 from the engaging part 120 to the operation part 110, and then finally supported by a rotary shaft of the driven pulley 104. Thereby, the door part 4 is locked.SELECTED DRAWING: Figure 2
【課題】機械式の施錠機構を備えた新たなホーム柵を実現すること。【解決手段】ドア収納部６の軌道側側面に、ドア部４の移動方向に沿って駆動プーリ１０３と従動プーリ１０４とを配置して両プーリ間に環状の索状体１０５を張設する。索状体１０５には、ホーム側へオフセットした位置にローラ１１１を突設する作用部１１０が固定されており、ローラ１１１がドア部４の軌道側側面に設けられた係合部１２０と係合する。作用部１１０は、全閉状態において従動プーリ１０４の真横に位置する。この全閉状態においてドア部４を開けようとする外力が加わった場合、係合部１２０からローラ１１１を介して作用部１１０へ伝わり最終的には従動プーリ１０４の回転軸で支持される。つまりドア部４は施錠状態となる。【選択図】図２
