    • A retrofitable retractable screen system for use with windows or doors. Instead of using a spring based tensioning arrangements to rewind the screen onto the roller assembly, the arrangement uses a pulley located on the spindle, around which is wrapped a cord. A guide assembly guides the cord around a tension adjustment arrangement that adjusts the tension in the cord as the screen is wound and unwound from the spindle to provide a smooth mechanism to extend and retract the screen. When the screen is extended, pushing the edge of the screen to force retraction of the screen is translated into a pulling action on the cord to unwind the cord off a pulley, which drives rotation of the spindle to wind the screen back on. Conversely, pulling the distal edge to extend the screen rotates the spindle and pulley to wind the cord back onto the pulley.
    • 一种可加装的可伸缩屏幕系统,适用于各种窗户或门。 代替使用基于弹簧的张紧装置将丝网重绕到辊子组件上,该装置使用位于主轴上的滑轮,其上缠绕有绳索。 导向组件引导帘线通过或围绕张力调节装置,该张力调节装置在丝网被卷绕和从卷轴展开时调节操作装置中的张力,以提供平滑机构来伸展和缩回丝网。 当屏幕伸展时,推动屏幕边缘以强制屏幕缩回转化为对帘线的牵拉动作,以将帘线从第一滑轮上解开,并且这驱动主轴旋转以缠绕屏幕 回来。 相反,拉动远端边缘以延伸丝网旋转主轴和滑轮以将软线卷回到第一滑轮上。
