  • Patent number: 5025848
    Abstract: An improved temporary window shade (10) that is designed to cover a window opening during the period when a person is awaiting the arrival and installation of a permanent window covering. The shade (10) consists of a non-woven, translucent material (12), having imprinted on its surface a grid (14) of vertical and horizontal lines that allows the material to be accurately and easily cut to size. The material (12) may be attached to either a window (50), a window sash (52) or to a wall (56) that surrounds a window frame (54). The attachment is made by first attaching a material attachment means, such as a two-sided adhesive tape (16), to the attachment structure. The material's upper edge (12c) is then pressed against the two-sided tape to hold the material in place. The shade (10) may bge partially raised by attaching at its lower corners a bendable strip (20).
