ABSTRACT:
A removable window safety guard for a window is provided which consists of a frame mounted within a window opening between side jambs when a lower window sash is raised. A mechanism operated by a control knob is for opening and closing louvers mounted within the frame. A retainer extends between the control knob and one side jamb of the window for preventing removal of the frame from the window opening, so that a child cannot fall out and an intruder cannot enter through the window opening.
