Abstract: An inexpensive, portable desktop bookcase is an open-sided carton suitable for holding a small number of books. The desktop bookcase allows the books to be portably stored together on the desktop, conveniently accessible, removable and replaceable. The bookcase carton is formed from folding a two-dimensional production blank, resulting in a storage unit which is suitable for its desktop purpose, as well as for transporting books from one location to another.

Abstract: A bookend that is formed from a single piece of sheet metal that is folded into a base, an upright, and a brace that has a free end. The single piece of sheet metal has a pair of edges and a fold line. The fold line and one edge form the base therebetween and the fold line and the other edge form the upright therebetween. The upright is maintained upright relative to the base by the brace. The base is divided into an outer base and an inner base. The inner base is cut out of the outer base and is coplanar therewith when folded outwardly therefrom. The upright is maintained vertical relative to the base when the brace is folded diagonally outwardly from the upright and the free end of the brace is affixed to the inner base.

Abstract: The present invention is a free-standing assembly of identical or similar modules with vertical panels that can support all kinds of reading and writing materials including books, binders, magazines, and files, in an upright manner. The multiple panels in an assembly can keep a set of the materials uprightly while users freely withdraw from or insert some copies into the set. The space between panels is adjustable to fit various thickness of the reading and writing materials between the panels. The total length of the assembly can be adjusted by changing the number of modules in the assembly. The modules are solidly interlocked with each other by snapping the notches on an arm and feet of one module to narrowing gaps at the openings of neighboring modules. The assembly requires no additional parts and tools. Thus it is easy to assemble and the manufacturing cost is low. Yet the structure of the assembly is rigid due to the interlocked arms and feet of the modules.

Abstract: 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.

Abstract: A bendable bookend having a first, non-operating position wherein the bendable bookend includes a substantially flat planar piece and a second, operating position wherein the bendable bookend includes a base and a support member extending upwardly from the base. In the non-operating position, the bendable bookend includes a base, a tongue extending from the base in a plane that is coplanar with a plane defined by the base, and a support member extending from the base in a plane that is coplanar with the plane defined by the base and in a direction toward the top end. In the operating position, the formed up bookend includes a base, a tongue, and an upstanding support member. The tongue extends from the base in a plane that is coplanar to a plane define by the base, and the support member extends upwardly from the base. Preferably, the bendable bookend includes a stiffening structure to help strengthen the formed up bookend.
