## Abstract

A modular library system for computer cartridges has stationary and mobile racks. Each of the racks comprises a plurality of spaced "T" shaped vertical supports. The vertical supports define vertical spaces for receiving cartridge holding trays or packs. The "T" shaped supports have tabs for holding the packs. The "T" shaped supports are interconnected by a top panel, a rear panel, a mounting base and a spreader. The spreader interlinks with all the vertical supports for providing structural rigidity.

## Claims

### Claim 1

A modular library system for computer cartridges comprising:
A) a plurality of stationary racks disposed side by side; and
B) at least one mobile rack coupled to and movable with respect to said stationary racks;
C) each of said stationary and mobile racks comprising
1) a plurality of "T" shaped vertical supports, each said vertical support being of integral, one-piece construction, and having a generally planar central element including a front bend, and first and second rear wall elements connected orthogonally to said central element at respective first and second locations distal to said front bend, said central element forming a double-thick, rigid, vertical partition wall, said partition walls of said "T" shaped supports forming a plurality of vertical spaces for receiving a plurality of cartridge-holding trays, and having a plurality of tray-supporting tabs to retain said cartridge-holding trays;
2) a top panel interconnecting said "T" shaped supports proximate a top end of said supports;
3) a mounting base interconnecting said "T" shaped supports proximate a bottom end of said supports, said mounting base including an outer box, and a plurality of bracing elements disposed within said outer box and extending in a direction parallel to said central elements and attached to said central elements; and
4) means for maintaining said "T" shaped supports generally parallel with one another, including a spreader for interconnecting said central elements proximate said central bends thereof and intermediate said top panel and said mounting base, and a planar, strip-like rear panel attached to said rear wall elements of said "T" shaped supports intermediate said top panel and said mounting base.

### Claim 2 (depends on 1)

The modular rack system in accordance with claim 1, wherein said spreader includes a plurality of spaced notches that interfit with a plurality of forwardly located edge notches provided on said partition walls.
