Stackable, portable filing cabinet modules

摘要

A module of a filing cabinet houses in a pivotal-lid covered filing cabinet a pendent file. Four castors at respective corners retract upward into the housing for providing compact, fixed-location, vertically stackable storage of a plurality of such modules. With the castors extended a module can be drawn along behind the user at the end of a length of line, transporting heavy loads of documents held in the pendent file. A lever-powered spring-biased system actuated by lines holds the castors up-or-down as desired, and a key-lock may be used to secure the lid.
