  • Patent number: 6357796
    Abstract: A book clip formed of flexible elongated material such as wire that rebounds readily to its formed shape. The clip has two legs for slipping behind pages of a book on the right and left sides of the book. The legs are slightly further apart at the bottom for easy insertion between pages. A front crosspiece holds the pages of the book across the of the open pages so that the pages are pressed between the crosspiece and the right and left legs. The legs and crosspiece are joined by approximately parallel left and right arch pieces. The legs extend beyond the lower part of the crosspiece sufficiently so that they easily remain between the pages of the book when the book clip is slipped up for the pages to be turned. The book can then be stood up on its own, laid down, or propped against another object, thus leaving the hands free to write, eat or do other activities while a person has access to the open pages.
