  • RETRACTABLE SCREEN SYSTEM PROVIDING A POSITIONING FORCE FOR A MOVABLE SASH
    Publication number: 20100229468
    Abstract: A door with a moveable window sash and a method of operating the same. The door includes vertical jambs with vertical channels. A window sash is movable in the vertical channels. A retractable screen assembly is attached to the door. The retractable screen assembly includes a roller, a flexible screen attached at a first end to the roller and at a second end to the movable window sash, and a biasing mechanism adapted to apply a continuous torque to the roller. The torque generates a positioning force on the window sash equal to at least 50% of the force of gravity acting on a window sash, such that the window sash can be positioned at an infinite number of locations along the vertical channels.
