Abstract:
A roll-up screen door appliance for drawing a screen panel horizontally across the span of a door frame, which advantageously may be stably positioned in a partly open position for permitting persons to pass through with a minimum opening, thereby reducing the opening size for entry of insects. The screen panel is rolled up on a spring-biassed, vertically-oriented supply roller and is withdrawn by a manually moved pull rod clamped to the distal end of the screen panel. The pull rod is frictionally held in a stable position across the span of the accompanying door frame as it is withdrawn and the friction is overcome manually as the screen is retracted upon the storage roller by a spring biassed mechanism. A hollow rubber tubing, resting on both sides of a U-shaped channel across the span of the door provides a frictional clamp against end structure upon the pull rod which resides in both top and bottom channel members as it travels across the span of the door and tautly stretches the screen panel in position adjacent the corresponding door framework. The screen is protected against intrusion of insects by means of opposing brushes contacting upper and lower screen panel edges across the width of the door span as the screen panel is withdrawn from the roller.
