PROBLEM TO BE SOLVED: To provide a platform fence that has a simple structure, and prevents a hand of a person or his or her hand baggage from being caught between two barrier parts to be low-cost and superior in safety.SOLUTION: A moving pulley 26 (equivalent to a fly block) is suspended in a right column part 13 by a belt 21, which is wound/unwound by a driving pulley 24. The moving pulley 26 is fixed with a first barrier rod 11 through a first barrier rod connection direct-acting part 42 capable of sliding up and down. Further, a second fixture 44 for connecting a second barrier rod 12 is fixed in a region, moving up during winding by the driving pulley 24, of the belt 21 and at a position below the first barrier rod 11. For change from a fully closed state to a fully open state, the first barrier rod 11 and second barrier rod 12 gradually decrease in mutual interval while moving up associatively and in the fully open state, the interval between both the barrier rods is minimized.SELECTED DRAWING: Figure 4
【課題】簡易な構造とすること。また、２つの遮断部の間に人の手や荷物が挟まることのない低コストで安全性に優れた昇降式ホーム柵を提供すること。【解決手段】右支柱部１３内に、ベルト２１で移動プーリ２６（動滑車相当）を吊り下げ、駆動プーリ２４で巻き取り／巻き戻しする。移動プーリ２６は上下にスライド自在な第１遮断棒連結直動部４２を介して第１遮断棒１１と固定されている。また、ベルト２１のうち、駆動プーリ２４による巻き取り時に上昇する部位で、且つ第１遮断棒１１よりも低い位置に、第２遮断棒１２を連結するための第２固定具４４を固定する。全閉状態から全開状態にする場合、第１遮断棒１１と第２遮断棒１２は連動して上昇しつつ両者の間隔は徐々に狭くなり、全開状態になると両遮断棒の間隔が最小となる。【選択図】図４
