Abstract

Mechanisms are provided to thwart an overtorquing attack on a cylindrical lockset. The cylindrical lockset comprises a lock cage, a split retractor assembly, and a torque-attack-activated spring-loaded blocker assembly coupled to the lock cage. The blocker assembly is set to a default non-blocking configuration. An overtorquing attack triggers the blocking assembly into a blocking setting. When in the blocking setting, the blocking assembly blocks movement of at least an outside door portion of a retractor assembly from translating into a latch-retracting position, but does not block the inside door handle from retracting the latch. A new split retractor assembly is also provided.
