  • Patent number: 7452094
    Abstract: A magnification apparatus that includes a foldable base, battery-powered lighting and an attached magnification sheet which can positioned over a book placed on top of the foldable base. The base has a left backing and a right backing which are connected to one another via a rubber hinge. The magnification sheet is connected to the top end of the base by a flexible bar and is capable of being placed over and above a book that is placed on top of the base for reading purposes. Both the left backing and right backing have separate light compartments that will provide lighting when the magnification apparatus is in use, with each of these lighting compartments being battery-powered through a separate battery compartment. Also, each of the backings has a set of teeth designed to prevent a book or other reading object from slipping off of the backings, with the teeth also interlocking to allow the left backing and right backing to be folded against one another.
