Abstract

Abstract A bookmarker comprises an inserted or first section adapted to extend along one side of a page or leaf of a book or the like, a tongue extending from the first section and adapted to extend on the other side of the page or leaf and cooperating with the first section to hold the marker to the page or leaf with a wedging action, and a flexible second section which is adapted to extend from the first section and the page or leaf. The first section or second section, which is visible even if the book is closed, may carry printed or written messages. The relative flexibility of the second section permits the bookmarker to bend should the marker be forced toward the book, as if dropped, or even tapped slightly, so that the pages of the book are not damaged.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 310 words
A bookmarker adapted to be placed between one or more leaves of a book, but being freely removable therefrom, said bookmarker comprising an integral sheet of single ply paper material of a thickness substantially greater than and an initial flexibility substantially less than that of the leaves of the book, said sheet material being between 28 to 65 pound in weight and forming a first section for securing the marker to the leaves and an adjacent second section extending a substantial distance above and from the leaves, said first section having an integral rectangular tongue cut therefrom, said tongue having a free end extending away from said second section, the remainder of said first section and said tongue being adapted to engage the leaves therebetween to hold said bookmarker temporarily in place on the leaves, indicia adjacent the juncture of said first and second sections for indicating said first section should be bent at an angle relative to said second section, said first section being bent at an obtuse angle to said second section at said juncture to form a weakened section to increase the flexibility of said bookmarker to that greater than the leaves of the book, said second section extending substantially above the leaves of the book, being out of contact with the same and having both sides thereof observable even with the book closed, said second section carrying a written message to be conveyed to the user of the book, whereby should said bookmarker be in place in the book, the message is visible, and should the book be dropped so that the extended second section of said bookmarker is struck, said bookmarker flexes at the weakend junction between the first and second sections and prevents said tongue and remaining portion of the first section from being driven inward onto the leaves to prevent damaging the book.

A bookmarker adapted to be placed between one or more leaves of a book, but being freely removable therefrom, said bookmarker comprising an integral sheet of single ply paper material of a thickness substantially greater than and an initial flexibility substantially less than that of the leaves of the book, said sheet material being between 28 to 65 pound in weight and forming a first section for securing the marker to the leaves and an adjacent second section extending a substantial distance above and from the leaves, said first section having an integral rectangular tongue cut therefrom, said tongue having a free end extending away from said second section, the remainder of said first section and said tongue being adapted to engage the leaves therebetween to hold said bookmarker temporarily in place on the leaves, indicia adjacent the juncture of said first and second sections for indicating said first section should be bent at an angle relative to said second section, said first section being bent at an obtuse angle to said second section at said juncture to form a weakened section to increase the flexibility of said bookmarker to that greater than the leaves of the book, said second section extending substantially above the leaves of the book, being out of contact with the same and having both sides thereof observable even with the book closed, said second section carrying a written message to be conveyed to the user of the book, whereby should said bookmarker be in place in the book, the message is visible, and should the book be dropped so that the extended second section of said bookmarker is struck, said bookmarker flexes at the weakend junction between the first and second sections and prevents said tongue and remaining portion of the first section from being driven inward onto the leaves to prevent damaging the book.
