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. <IMAGE> |
