DOOR WITH RETRACTABLE SCREEN
A door incorporating at least one movable glass insert or window sash slidably disposed in at least one track thereof. An end of the insert is coupled to an end of a spring biased roll of screen. As the insert moves from the spring biased roll, the screen is extracted therefrom providing a continuously variable screened region in the door. The insert can be positioned using a counterbalance, spaced apart latchable locations in the door, frictional engagement, or through the tension force of the biased roll of screen. A catch mechanism is disposed on the movable glass insert to detachably couple the glass insert to a portion of the door.
