Abstract
An override mechanism is for an electronic door lock assembly that includes a handle, a retractor and an electronic clutch mechanism with a movable coupler and an actuator. The coupler operatively connects the handle with the retractor when the coupler is located in an engaged position and the actuator is operable to displace the coupler between a nonengaged position and the engaged position. The override mechanism includes a movable override member configured to displace the clutch coupler between the nonengaged and engaged positions. The override member also retains the clutch coupler at the engaged position when the override member is disposed at an unlock position and prevents displacement of the coupler during actuator operation when the override member is disposed at a lockout position. Further, a manual drive, preferably including a cylinder lock, is configured to displace the override member between the unlock and lockout positions.
