ABSTRACT:
A new book holder comprises two book receiving members and a connecting member which connects the two book receiving members together so that they can move toward and away from one another between two positions to hold respectively a small width book and a maximum width book. Each receiving member has a post member on its upper surface carrying a respective page engaging member pivoted thereon and spring biased to be movable between a position in which it contacts the surface of the respective book receiving member, and one in which it can contact the upper surface of the uppermost page of a book resting on the book receiving member. Preferably each page engaging member is of U-shape and is of springy wire material, so that it can flex to assist in urging the page engaging member into contact with the holder surface. The parts of the page engaging members in the posts may comprise torsion springs as part of the spring means. Each page engaging member preferably has its two side portions cranked to be concave toward the holder upper surface, so as to maintain engagement when the part of the book is thicker than the height of the pivot axis above the page receiving surface, and the end portion may be cranked along its length to provide downwardly extending corners that engage with the book uppermost page. Preferably the book receiving members are hollow and the connecting member slides within them. The book receiving members may be provided on their under surfaces with respective magnetic strips for attachment of the book holder to a ferrous metal surface, and the book receiving members and the connecting member may be provided on their upper surfaces with respective measuring scales.
