ABSTRACT A cabinet with two or more drawers suitable for filing records in the form of index cards or the like and comprising a substantially vertical, longitudinally displaceable sliding bar provided opposite each drawer with a blocking means adapted to co-operate with the pertaining drawer so that in one position of the sliding bar it blocks the drawer and in another position of the sliding bar it releases the drawer to allow it to be pulled out. When a drawer is pulled out the sliding bar assumes its blocking position and blocks the other drawers to eliminate the risk of the cabinet being overturned when two or more heavily loaded drawers are pulled out simultaneously. Known drawers of this type, in which a sliding bar is positioned on either side of the drawers suffer from the drawback that they require great precision and rigidity of manufacture because even a modestly oblique pull in a drawer can activate a sliding bar on one side. The invention provides a sliding bar disposed at the rear side of the cabinet and for each drawer there is provided a spring which tends to urge the sliding bar into the blocking position but is prevented from doing so by the corresponding drawer when the drawer is in its closed position.
