Abstract: A vertical guide for a roll-up type screen as used on windows and doors can be used either inside or outside as desired. The guide is placed in opposing relation on the left and right sides of the window or door and includes a first U-shaped retainer which is frictionally attached to a base. The guides allow the user to purchase screens for windows having various width openings since the guides can be adjusted horizontally to seal the edges of the screen and prevent insect and debris infiltration.

Abstract: A retractable window screen assembly which includes a housing easily mounted on an existing double hung sliding window sill or similar type is disclosed. The screen is wound about a spring mounted core and extends from the housing when the window is opened to cover the open space. A pivot bar provides screen to sash rotation to prevent binding when the sash yaws during opening or closing. The core includes a c-shaped member for easy attachment to a generally cylindrical member and a U-shaped member attaches the free end of the screen to the pivot bar.

Abstract: The invention herein pertains to a screen for use with a conventional multiple-hung window. In the one embodiment, the window screen can be concealed in the bottom lateral member of the sash frame and unwound as the sash is raised thus providing an automatic window screen. When the sash is closed a spring-loaded axle causes the screen to tightly rewind within the sash cavity.In the preferred form, an apron is provided below the window stool for housing a screen coil in which a free end is affixed to the bottom lateral member of the lower sash. A pivot bar attached to the lower sash allows the screen to evenly unroll even when the window sash yaws due to uneven pressure thereon or the like during opening and closing.
