ABSTRACT:

FIELD OF INVENTION
The present invention relates to window assemblies and apparatus for protecting the interior of such windows and, more particularly, to an improved quick release sacrificial shield for protecting window assemblies.
BACKGROUND
U.S. Pat. Nos. 5,242,207 and 5,735,089 describe and illustrate window protectors comprising the current state of the art and are incorporated herein by this reference.
While it has been recognized that the protective shields for window assemblies such as shown in the foregoing patents should be easily attachable to and detachable from window assemblies, there is still a need for improvements in connecting structures better enabling such easy attachment and detachment. The present invention satisfies such needs.
SUMMARY OF INVENTION
In the present invention, the frame of the window assembly provides support for both the window and the protective shield. Such support comprises an inwardly facing saddle which supports the window within the frame and an inwardly facing casing and retainer adjacent the saddle which releasably retains the protective shield and the window within the frame with the shield extending over and protecting the window.
