  • Patent number: 6084711
    Abstract: The Folding Laptop Computer Shade is a device designed to reduce the amount of ambient light adversely affecting the viewability of portable laptop/notebook computers. It is essentially a four (4) sided collapsing box, which when expanded and placed directly over the entire computer, effectively shields the display from outside light sources enough to make comfortable viewing possible. The device is of relatively simple construction, made from cloth, plastic, and other existing materials readily available. It is designed to fold flat when not in use, for easy storage in typical laptop computer cases, without the need for an extra package or a larger case. It is equipped with removable, adjustable legs for viewing and access adjustment, as well as easy storage. It consists of five (5) parts, the shade box itself, and four (4) legs.
