Abstract
Abstract A pair of book-cover-size panels are joined by a flexible web, so that when book is closed one panel overlies each book cover and web overlies book spine. Flaps hinged to upper edges of panels are located against inner surfaces of book cover to connect panels to covers. Panels may be swung rearwardly to serve as book prop. A single flexible band, which may be stretchable, is secured at its ends to the panels, extends around the pages of an opened book, and extends between the flaps at their lower edges, to limit rearward swing of panels, hold pages down, and prevent accidental separation of the device from the book.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
269 words
For use with a conventional book having front and back covers and an intermediate spine to which the pages are bound, a combination book protector and reading prop comprising a pair of stiff panels having a size comparable to that of the book covers and adapted to be placed against the outer surfaces of the book covers, respectively, a flexible connector between said panels adapted to extend across the spine of the book, means articulating the upper edges of said panels in hinged relation to the corresponding upper edges of the book covers, said articulating means comprising flaps of stiff material hingedly connected to the upper edges of said panels and adapted to lie flat against the inner surfaces of said book covers, respectively, an opening in each of said flaps, whereby the panels can overlie and protect the book when it is closed and can be swung rearwardly away from the book covers to serve as props when the book is opened, and a single flexible band having ends secured to said prop panels, said band extending forwardly from its end and adapted to overlie the pages of an open book, and said band extending through said openings in said flaps, and means for preventing said band from being removed from said openings by movement with respect to said flaps in a direction away from said articulating means, so that said band serves simultaneously (a) to limit the rearward swing of said panels, (b) to hold the book pages down, and (c) to prevent the book covers from accidentally sliding out from between their respective panels and flaps.

Claim 3
Dependent Claim
37 words
A combination book protector and reading prop as defined in claim 1 wherein said flexible band is stretchable to permit adjustment of the angle between each book cover and its respective prop when the book is opened.
Claim 4
Dependent Claim
43 words
A combination book protector and reading prop as defined in claim 1, in which said flaps are comparable in size to the book covers themselves, the book covers thus being protectively sandwiched between the panels and the flaps when the book is closed.
Claim 5
Dependent Claim

A combination book protector and reading prop as defined in claim 1 wherein said band extends from each of its ends to a point of connection with one of said flaps at the lower edge of the latter, said band extending between each of its ends and said point of connection at an angle downwardly and toward said flexible connector.
Claim 6
Dependent Claim
31 words
A combination book protector and reading prop as defined in claim 1 including a sliding connection between said band and each of said flaps at the lower edges of the latter.
Claim 7
Dependent Claim
