Abstract
Abstract A book holder formed preferably from a sheet of transparent synthetic resin of suitable thickness to render it relatively stiff and including a book-supporting panel disposed at an acute angle relative to a supporting surface such as a table or the like, a bracing panel extending angularly rearward and downward from the upper edge of the supporting panel, and a transparent holding and viewing panel spaced sufficiently from the booksupporting panel to accomodate a book in open condition and overlying the exposed pages of the book to render the same visible and prevent contact of the surfaces of the pages by any extraneous material. The book-supporting and transparent holding and viewing panel form a slot to receive a book in open condition, the lower edges of the two panels being connected by a short section of the material comprising a ledge upon which the lower edge of the book rests, and the lower edge of the supporting panel also preferably being bent smoothly outward to form a flange capable of serving as an additional book supporting ledge in relation to the bracing panel.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
282 words
A book holder formed from resilient transparent material and comprising in combination a book supporting panel adapted to be supported at an acute angle to a supporting surface such as a desk or table and being of a width adequate to underlie the open covers of a book to be supported thereby in open position, a bracing panel connected to the normally top edge of said supporting panel and extending downwardly and away from the same for contact of the lower edge thereof with said supporting surface at an acute angle thereto, a ledge extending along and outwardly from the lower edge of said supporting panel to receive the lower edge of a book when disposed against said supporting panel, and a substantially flat transparent holding and viewing panel at least as wide as and connected to and extending upward from the outer edge of said ledge and overlying said supporting panel to form a channel of sufficient depth to receive a book in open position and adapted to support and maintain said book in such open position for viewing of the pages thereof through said transparent panel, the upper edge of said transparent panel extending above the upper edge of said supporting panel a predetermined distance to provide an adequate protection surface and said transparent panel also being closer to the upper edge of said supporting panel than the bottom edge to accommodate the holder to a range of different thicknesses of books and the width of said transparent panel being adequate to cover at least the printed matter on a pair of open pages of a book to protect the same and support said pages in a readily viewable manner.

A book holder formed from resilient transparent material and comprising in combination a book supporting panel adapted to be supported at an acute angle to a supporting surface such as a desk or table and being of a width adequate to underlie the open covers of a book to be supported thereby in open position, a bracing panel connected to the normally top edge of said supporting panel and extending downwardly and away from the same for contact of the lower edge thereof with said supporting surface at an acute angle thereto, a ledge extending along and outwardly from the lower edge of said supporting panel to receive the lower edge of a book when disposed against said supporting panel, and a substantially flat transparent holding and viewing panel at least as wide as and connected to and extending upward from the outer edge of said ledge and overlying said supporting panel to form a channel of sufficient depth to receive a book in open position and adapted to support and maintain said book in such open position for viewing of the pages thereof through said transparent panel, the upper edge of said transparent panel extending above the upper edge of said supporting panel a predetermined distance to provide an adequate protection surface and said transparent panel also being closer to the upper edge of said supporting panel than the bottom edge to accommodate the holder to a range of different thicknesses of books and the width of said transparent panel being adequate to cover at least the printed matter on a pair of open pages of a book to protect the same and support said pages in a readily viewable manner.
Claim 3
Dependent Claim
63 words
The book holder according to claim 1 in which the lower edge of said bracing panel terminates in an outwardly smoothly bent flange extending substantially perpendicularly to the plane of said bracing panel and thereby providing a smoothly curved lower edge upon said bracing panel and said flange being adapted to serve as an additional book supporting ledge relative to said bracing panel.
