ABSTRACT:
An insulative window shade assembly of the roll-up type for windows or like openings comprises a flexible sheet of shade material essentially of the size in area of the window or other opening to be insulated. The flexible sheet of material in its inoperative position is contained in a header or casing mounted at the top of the opening and extending across the width of the opening. The casing contains a spring-actuated roller upon which the sheet of shade material is wound with the leading edge protruding through a longitudinal slot or opening in the casing. The system further provides two side guides or channels mounted at the sides of the window or opening, and in which the channels contain a pile fabric to seal the sides of the flexible sheet when unrolled to the operative or insulative position. The leading edge of the sheet of flexible material is provided with a bar or rigid member constructed with means for securing it in a co-acting gripping device at the base of the window or opening whereby the shade is secured and sealed at the base or bottom of the window. The gripping means is desirably adjustable so that it can be secured on a horizontal or vertical supporting surface. The system is featured by side guides which are of flexible or hingeable nature or are readily separable into front and back portions whereby they can be opened over at least the lower portion of their lengths to permit a free downward pull upon the sheet so as to activate the spring mechanism of the roller to readily wind up the shade, when desired.
