To provide an opening/closing safety fence for a platform that can be easily manufactured and installed at low cost.SOLUTION: The opening/closing safety fence for a platform is installed on the platform and includes a plurality of columns and a safety fence. The safety fence has a cylindrical object including a large-diameter cylinder and a small-diameter cylinder whose diameters are different from each other. When the safety fence is opened, the small-diameter cylinder is housed in the large-diameter cylinder. When the safety fence is closed, the small-diameter cylinder housed in the large-diameter cylinder is moved in a lateral direction by an expansion mechanism such that the small-diameter cylinder serves as a fence. In the expansion mechanism, fitting means connected to a motor, which is mounted on the column, is fitted to the small-diameter cylinder to move the small-diameter cylinder in the lateral direction.SELECTED DRAWING: Figure 1
【課題】安価で且つ簡単に製造・設置することができるプラットホーム用開閉安全柵を提供する事。【解決手段】プラットホームに設置される複数の支柱と安全柵とからなるプラットホーム用開閉安全柵であって、安全柵は、口径の異なる大口径筒と小口径筒からなる筒状物を有し、安全柵の開放時には大口径筒内に前記小口径筒が収容され、安全柵の閉鎖時には大口径筒内の小口径筒が、伸縮機構により横方向に移動することで小口径筒が柵となるように構成され、伸縮機構は、支柱に取り付けられたモーターに連結された嵌合手段と小口径筒とが嵌合し、小口径筒を横方向に移動させる。【選択図】図1
