The largest structural member of the book holder is its back which is formed of injection molded flexible synthetic polymer composition material. The support for the back is molded in the plane of the back and is joined thereto by means of living hinge structure. A book clamp is formed so that it faces the back to resiliently engage the edge of a book therebetween. The book clamp is preferably unitarily formed with the back and is pivoted with respect to the back by means of a living hinge.

A book holder comprising: a substantially planar back for the support of a book thereon, said back having left and right edges, a top edge and a lower edge; left and right slots in said back adjacent said left and right edges and a cross slot in said back spaced from said bottom edge, said cross slot intersecting said left and right slots, left and right support legs respectively positioned in said slots adjacent said left and right edges of said back, said left and right support legs each being pivoted with respect to said back, a foot secured without hinging to both said left and right support legs so that said foot extends from adjacent said left edge to adjacent said right edge for supporting said back at an acutely angular orientation with respect to a support surface when said foot and the lower portion of said support legs are swung out of their slots and when both said bottom edge of said back and said foot are engaged on the support surface, there being a downwardly directed tongue forming a part of said back with said tongue extending downwardly between said slots adjacent said left edge and said right edge; a flange secured to said back and extending substantially from said left edge to said right edge of said back and extending forwardly from said back to act as a book stop, said flange being positioned adjacent said bottom edge of said back; a clamp bar pivotably mounted on said flange, said clamp bar having a clamp jaw extending substantially from said left edge to said right edge of said back and extending above said flange and facing said tongue above said flange; a spring interengaged between said back and said clamp bar to urge said clamp jaw towards said tongue to clamp a book against said tongue so that said tongue can resiliently bend backward from the clamping force of said clamp bar against a book.
