ABSTRACT:
A file follower locking assembly selectively locks and releases a follower plate behind the files in a drawer by using two opposed follower guides with eccentric cam grippers to engage upper and lower surfaces of open wall channels formed in the drawer sides. In a first mode of operation, the cam grippers provide a firm gripping engagement with the upper and lower surfaces. The grippers are released for sliding movement of the assembly along the drawer in a second mode of operation.
