Abstract:
A window with an outer frame for mounting in a window opening in a structure this outer frame having on the sides thereof sash tracks or channels facing one another across the window space. Window sashes containing a single window pane are positioned between and securable in such channels in a manner allowing them to be slid therealong for opening and closing the window. Protuberances extending from the window frame secure the window sashes in the channels so as to allow sliding therealong, and removing such window sashes from those channels is accomplished by removing the protuberances therefrom. A blocking panel is positionable in the outer frame in the absence of such window sashes, and can be removed therefrom in the absence of such sashes but not when the sashes are present. A relatively rigid tube structure that can be formed in a coarse mesh is provided for affixing to the panel frame in the blocking panel as is a finer mesh screen structure to thereby provide security against entrance through the window space.
