First Claim
Patent Images
1. An electronic lock, comprising:
- an outer body having a bore and configured to be mounted to an object;
a rotatable core comprising a plug rotatably positioned within the bore and movable relative to the bore in an unlocking direction during a normal unlocking operation; and
a solid-state actuator positioned in the plug and configured to resist movement of a locking member during a non-normal unlocking operation, wherein the locking member is at least partially positioned within a recess of the plug.

Abstract
An electronic lock includes a rotatable core movable within an outer body. The rotatable core includes an actuator configured to move a tumbler blocking member into or out of interfering engagement with one or more tumblers. In an unlocked state, the actuator moves the tumbler blocking member so that a movable locking member in the rotatable core that engages the outer body can be moved into the rotatable core. In a locked state, the actuator positions the tumbler blocking member to prevent the one or more tumblers from retracting and thereby retain the locking member in a channel of the outer body.
