ABSTRACT:
A window insert assembly is disclosed having a spring-biased frame construction used to secure the insert within existing window frames of varying size. The insert assembly is particularly useful for mounting interiorly of an existing window pane to form a "double pane" insulative window structure, i.e., by creating a thermal cavity between the interior side of the existing window pane and the window pane of the insert. The insert assembly comprises a solid pane, such as a glass pane, mounted in a first frame. The first frame is received within a second frame which has movable sides for changing the size of the second frame. Springs are provided between the second frame and the first frame, preferably on all four sides of the rectangular window insert assembly, which bias the second frame outwardly relative to the first frame. The size of the second frame is adjustable by pressing one or more sides against this bias to fit the insert within an existing window frame in which it is to be installed. Once in place within the window frame, the second frame is released. The spring bias presses the second frame sides into engagement with the window frame, creating a compression fit between the insert assembly and the window frame. The window insert assembly is readily installed without any tools, and is adjustable to fit varying size window frames.
