发明名称 Interlocking bookends
摘要 A book holder system comprising first and second book ends, each bookend having a substantially planar vertical surface for engaging at least one object such as a book, or the like, that is to be held between the bookends. Each bookend has a horizontal leg that underlies the objects to be held between the vertical surfaces. The horizontal legs of the first and second bookends have complimentary-shaped interlocking projections and recesses. The projections permit disengagement of the first bookend from the second bookend only when the first and second bookends are moved in a vertical direction with respect to each other.
