Abstract
An anti-fall device for a window sash comprises a window-sash fixing block, a window-frame fixing block, an elastic metal wire and a pipe. The elastic metal wire connects the window-sash fixing block and the window-frame fixing block. The window-sash fixing block is defined with a through hole into which the pipe is inserted. One end of the elastic metal wire is connected to the window-frame fixing block, and the other end of the elastic metal wire penetrates the through hole in the window-sash fixing block and enters the pipe. The end of the elastic metal wire, which penetrates the through hole, is fixed with a limiting block. The diameter of the limiting block is bigger than that of the through hole. The window-sash fixing block is fixed on the window sash, and the window-frame fixing block is fixed on the window frame.
