Abstract
Abstract An expandable modular storage system for holding slides and cassettes comprises storage compartments formed by a first wall element of C-shaped transverse cross-section having a pair of parallel facing walls integrally joined by a web or side wall normal thereto. The outer edge portions of the C-shaped elements are slidably interconnected with additional C-shaped elements along the opposite edges of the side wall to provide additional storage compartments as needed and a last compartment in a row is closed with a generally flat wall element having opposite edges slidably interconnected with the free outer edges of the walls of the last C-shaped wall element in a row. The storage system may include any number of rows of modular compartments and the rows are stacked vertically and interconnected with joining elements. Sliding drawers are provided when needed for the compartments and the drawers are dimensioned for containing slides and/or cassettes available for ready access and are compactly stored away in an orderly fashion when not in use. Any number of storage compartments may be provided in a stacked array of rows and columns which is expandable in vertical and horizontal directions as additional storage compartments are needed. The array may comprise a pattern that is widely variable to match the available spaces adjacent a wall or other surface.
