ABSTRACT:
A window safety system having a first and second vertical track installed as mirror images on opposite sides of a window frame. The system utilizes at least one elongate blocking element which extends across the window width and is secured to opposing guide elements which smoothly travel within the vertical tracks. A system cover is engaged at opposite ends to guide elements which travel in the vertical tracks. The guide elements are connected in series to one another by a flexible belt within the vertical tracks. The system cover interacts with a lower rail of a window sash such that when the window sash is raised to an open position, the system cover travels with the lower sash. This travel in turn causes the guide elements to translate within the vertical tracks and guiding blocking rods to a position laterally across the opening of the window. The blocking rods thereby prevent egress of a child or the like through the open window. When the window is closed a reverse sequence occurs and the blocking rods are nested beneath the cover upon the window sill.
