  • Wire suspended projection screen
    Patent number: 12529949
    Abstract: A wire suspended screen includes a roller assembly and a screen assembly. The roller assembly includes an inner tube and a plurality of sleeves partially extending around the inner tube, defining a longitudinal recess along the roller. The sleeves are spaced apart, defining gaps. Wires are attached to the inner tube and wind over the outer surface of the inner tube in the gaps. The wires are attached to an upper slat of the screen assembly. As the roller is rotated, the wires wind and unwind from the inner tube to raise and lower the screen assembly, depending on the direction of rotation. When the screen assembly is raised, the upper slat fits into the longitudinal recess. As the screen is raised further, the screen assembly winds over the exterior surface of the sleeves and upper slat. The roller can be motor driven.
