ABSTRACT:
A file arrangement includes a cabinet housing, a plurality of vertically stacked file elements with an interlock assembly carried by one cabinet lateral wall precluding the opening of more than one element at a time as the first opened drawer vertically displaces a roller on the assembly to block any displacement of similar rollers adjacent the remaining file elements. A separate lock bar assembly adjacent the opposite cabinet lateral wall includes a plurality of lock dogs engageable with the front of the file elements and vertically shiftable upon actuation of a lock mechanism. Operation of the lock mechanism and its associated lock bar assembly also actuates a transfer rod joining both assemblies to simultaneously and equally displace the interlock assembly and a plurality of lock dogs thereon to lock both sides of all file elements within the cabinet.
