摘要
PURPOSE: A crossing domain and frog controlling method, which can secure higher stability than a frog with a straightly expanded wheel tread, is provided to be locked by contacting a frog to a wing rail to prevent a gap between the leading end of a frog and a wing rail.;CONSTITUTION: A crossing domain and frog controlling method comprises wing rails(12,14) and a crossing(16). The wing rail has bendable points(26,28,30,32). The wing rail has a route which is concavely bent between the bendable points corresponding to a frog(18). The frog is locked at the bendable points and connected to the wing rail without a gap. The frog is locked with closing devices(40,42). The closing device is expanded to the leading end of a first closing device.;COPYRIGHT KIPO 2011
