ABSTRACT:
A dual-function lock in accordance with the invention has an axis-defining lock sub-assembly including first and second axially aligned rotator members having confronting first end faces and oppositely facing second end faces. The sub-assembly has a lost-motion recess and an anchor recess on one confronting face and one recess-engaging member extending from another confronting face to permit lock function selection by placing the recess-engaging member into a particular recess. Alternative dual-function lock sub-assemblies include a unitary rotator bolt and a companion actuator. The rotator bolt has a release-mechanism-engaging portion and an actuator-engaging portion. While a first section of the actuator-engaging portion permits limited lost-motion between the rotator bolt and a companion actuator, a second section prevents lost-motion. The lock function can be selectively determined by placing the companion actuator into the desired first or second section of the actuator-engaging portion.
