This technology is a blind that adjusts its height by winding a screen around an upper take-up rod rotating within an upper ceiling frame. It features a noise-reducing support rod with embedded magnets at the bottom, which uses magnetic force to secure or detach the screen from the window frame.
While blinds are widely used to block sunlight and provide privacy while enhancing interior aesthetics, they often cause noise when windows are left open, as the wind causes the screen to sway and repeatedly strike the window frame.
This technology features a rotating rod inside the support rod case, with magnets of opposite polarities embedded along its length. Rotating the rod to face the same polarity as the window frame magnet creates repulsion, keeping the screen detached, while rotating it to the opposite polarity creates attraction, securing it to the frame. The window frame magnet can be embedded or attached as a removable unit. Suitable for apartment and residential living room windows, office and classroom ventilation windows, and hotel room windows, it allows for a quiet indoor environment without the rattling of screens flapping in the wind, even with windows open. It is also easy to install on existing frames by simply attaching the magnetic plate.
