ABSTRACT:
An adjustable window guard and screen apparatus includes an adjustable framework of two sections slidably mated to each other. Also, at least one set of screen members, and a plurality of bar members are affixed to the framework and are expandable or contractable upon the adjustment of the framework. Louver members having two slidably mating sections are further included and are each in engagement with a bar member. At least one section of a bar member having a louver member mounted thereon, is itself rotatably mounted to the framework. The louver member is mounted to the bar member so that rotation of the rotatably mounted bar member section causes rotation of the louver member. Like the screen members and bar members, the louver members will expand or contract upon the adjustment of the framework. However, in the present invention the bar members while functioning as a mounting for the louver members, are also constructed of a strong material so as to function as a security guard for the prevention of intrusions into a dwelling.
