ABSTRACT:
A protective enclosure for building openings such as windows and doorways wherein the protective enclosure comprises a peripheral frame member that circumscribes the openings and pivotally mounts a transparent shielding unit. The unit which may function as a window or door, depending upon the application, is provided with a unique hinge and locking arrangement which facilitates the easy opening and closing of the unit with respect to the opening; yet one which provides security against the unauthorized entry through the opening in that the unit may not be removed from the building opening from the outside of the building when the unit is in a closed position.
