Abstract: An interlock system for use in an array of retractable storage cradles. The instant system prevents the opening of more than one cradle at one time through a slide modified generally by a biased cam insertion-extraction means and a column of movable components. The system can be used in free-standing file cabinets as well as prefabricated and modular storage units.

Abstract: An adjustable divider for a shelf or a drawer of a file cabinet is formed entirely of a spring wire. One end of the spring wire is configured as an engagement portion which has a longitudinal portion for engaging within an acute angle between a first wall portion and a bottom surface of a notch in a horizontal base which supports files, books, or any other items to be maintained in an upright orientation. A second wall portion of the notch is substantially orthogonal to the bottom surface of the notch and maintains the longitudinal portion in resilient compression against the first wall portion of the notch.

Abstract: An improved shelf is provided with a divider arrangement formed of a substantially resilient material having portions for engaging with vertical and horizontal members of the shelf, the divider arrangement providing stiffening and support for the shelf.

Abstract: For use in a modular cabinet or the like system wherein one or more cabinet modules of unit width have rolling mobility along parallel rails which extend normal to the module-width dimension and at module-width spacing, the invention contemplates a floor-mountable track system of rigid interconnected modular rail and spacer members adapted to provide permanent guided support of one or more modules without anchorage to the supporting floor, whereby the system can be readily moved, rearranged, expanded or otherwise modified, without damage to or modification of the supporting floor. The invention also contemplates novel modular rollable base structure particularly applicable to the tiered support of cabinet modules on such a track system.
