(under subclass 134) Device wherein significance is attributed to a construction of a built-up open framework for supporting a shelf, which construction is readily assembled or erected to a form that is usable as a shelf support, or is readily disassembled or collapsed to a form that is not so usable but occupies less space, any of the operations being capable of performance without the use of tools.
(1) Note. The limitation "without the use of tools" applies to the constructing of a framework that is "assembled" by connecting together previously separate members or that is "erected" by positioning members that were previously loosely connected and tightening the connection between the properly positioned member, and also applies to the "knockdown" of a framework that is "disassembled" by disconnecting the members and separating them or that is "collapsed" by loosening the connection between the members and moving them together into a smaller space with the members still loosely connected together. However, the disclosed use of a common, multi-purpose tool such as, for example, a wrench, screwdriver or pair of pliers to tighten or loosen a nut-and-bolt arrangement would not bar a patent having such disclosure from this or an indented subclass.
