Abstract
A file cabinet provided with a housing which has a front opening, and which supports thereon a vertically-spaced plurality of drawer units supported for horizontal displacement between open and closed positions relative to the housing. A horizontally elongated but vertically narrow filler panel is positioned within the front opening of the housing between two vertically-spaced drawer units. The filler panel is disposed at a convenient working height which is preferably in the range of 24 to 36 inches above the floor. The filler panel mounts thereon a key-operated lock mechanism which is preferably centrally positioned both vertically and horizontally of the cabinet, and which activates locking bolts which project sidewardly of the cabinet for activating vertically-movable lock bars which are mounted for limited vertical displacement on the insides of the housing side walls. These lock bars having locking elements which engage the closed drawer units to hold them in a locked position. The filler panel can be formed as a posting shelf which itself is horizontally slidably movable between open and closed positions, which posting shelf mounts thereon the locking mechanism.
