A file follower locking assembly (100 selectively locks and releases a follower plate (20) behind the files in a drawer (8) by using two opposed follower guides (22 24), with eccentric cam grippers (42) to engage upper end lower surfaces (16a, 16b, 18a, and 18b) of open wall channels (16, 18) formed in the drawer sides (12 14). 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.

Why it's free to use
- Filed December 30, 1993 and granted June 12, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended December 30, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 30, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
