Abstract:
An interchangeable lock core that is configured to communicate with a token having an access code, the interchangeable lock core comprisinga core body, a lock actuator that is coupled to the core body for movement relative to the core body, the lock actuator having a passageway configured to receive at least a portion of the token, a token communicator coupled to the core body, a blocker movable between a first blocker position wherein the lock actuator is fixed to the core body and a second blocker position wherein the lock actuator is movable relative to the core body, at least one tumbler element movable between a first tumbler position and a second tumbler position, a spring positioned to lie between the at least one tumbler element and the blocker, and an electromagnetic actuator coupled to the core body and coupled to the token communicator, the electromagnetic actuator being movable between a locking position in which the blocker is locked in the first blocker position and a releasing position in which the blocker is movable from the first blocker position to the second blocker position, the spring being compressed between the at least one tumbler element and the blocker when the at least one tumbler element moves from the first tumbler position to the second tumbler position as a result of insertion of the token into the passageway, the electromagnetic actuator moving to the releasing position if the token communicator reads the access code, and the spring acting between the at least one tumbler element and the blocker to move the blocker from the first blocker position to the second blocker position after the electromagnetic actuator moves to the releasing position.
