Embodiment Construction

[0031] While this invention is susceptible of embodiment in many different forms, there are shown in the drawing and will be described herein in detail specific embodiments thereof with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the invention to the specific embodiments illustrated.

[0032] In one embodiment of the invention, an exterior door incorporates a replaceable screen module which includes an integral, spring biased, retractable screen which is coupled to a movable glass insert in the door. As the insert is moved from the screen, the screen is withdrawn from its retracted position and extends along the frame of the door screening the otherwise open region from which the glass insert has moved. As the window sash or insert moves in the opposite direction toward the screen module, the screen is retracted into the module reducing the ventilation region available in the do...

Abstract

An exterior door incorporates at least one moving glass insert or sash slidable in first and second spaced apart tracks. An end of the insert is coupled to an end of a spring biased rolled screen. As the insert moves from the roll, the screen is extracted therefrom providing a continuously variable length of exposed screen that exerts a retracting force on the insert. The insert may be supported at any one of a variety of positions by frictional forces exerted on the insert, or by the frictional and retracting forces, without need for counterbalances or latches.

RELATED APPLICATIONS [0001] This application is a continuation of U.S. patent application Ser. No. 10 / 606,039 entitled “Door with Variable Length Screen,” filed Jun. 25, 2003, which is a continuation of U.S. patent application Ser. No. 10 / 212,465, now U.S. Pat. No. 6,618,998 entitled “Door with Variable Length Screen,” filed Aug. 5, 2002, which claims the benefit of U.S. Provisional Application No. 60 / 310,557 filed Aug. 7, 2001.FIELD OF THE INVENTION [0002] The invention pertains to doors. More particularly, the invention pertains to doors having at least one slidable glass pane or panel with an extendable screen attached thereto. BACKGROUND OF THE INVENTION [0003] Storm doors which incorporate panes of glass and screens are known. Some forms of such doors include screens which are fixedly mounted to the frame of the door with sliding glass inserts. With these doors, the inserts usually can be locked into a plurality of vertical positions with spring loaded latches to expose varying...
