Abstract
The disclosure relates in general to a locking mechanism for a door. Specifically, the disclosure relates to a thumbturn latching mechanism having a triggered rotation-arresting assembly therein, configured to inhibit rotation of the lock mechanism upon unauthorized removal of the posterior portion of the latching mechanism, while still allowing for selectably bypassing the rotation-arresting mechanism from the anterior portion of the locking mechanism.
Claims8
A cylinder lock having an anterior end and posterior end along a longitudinal axis, the lock comprising:
- a. an anterior lock actuator assembly positioned axially anterior to a lock cam;
- b. the lock cam, adapted to lock and/or unlock the lock mechanism;
- c. a posterior lock actuator assembly comprising a knob operably coupled to a shaft positioned axially posterior to the lock cam;
- d. a clutch assembly, the clutch assembly being movable along the longitudinal axis between:
- i. a first position configured to transfer a rotational force path from the anterior lock actuator assembly to the lock cam;
- ii. a second position configured to transfer a rotational force path from the posterior lock actuator assembly to the lock cam;
- and
- iii. a third position in which the clutch is not movable along the axis, the third position triggered automatically upon removal of an anterior component of the cylinder lock,
- wherein the anterior lock actuator assembly is configured to bypass the third position.
