Abstract

A retractor assembly for a cylindrical lockset comprises inner and outer retractors. Each of the retractors has a cam engaging surface to convert rotary motion from the inside door handle into linear latch-retracting motion. Inner and outer spindles having retractor activation cams are configured to bear upon cam surfaces of the inner and outer retractors to retract the latch. When the inner door handle is operated, the inner retractor acts directly upon the tailpiece of the latch bolt assembly to retract the latch. When the outer door handle is operated, the outer retractor presses on the inner retractor, causing it to retract the latch. If there is an attack, a blocker assembly engages with members formed in the outer retractor to render the outer retractor inoperative to move into a latch-retracting position without interfering with operation of the inner retractor to move into a latch-retracting position.
