Abstract:
A lock system comprising:a lock core comprising a core body, a lock actuator coupled to the core body for rotation about an axis, a blocker movable perpendicular to the axis between a locking position in which the lock actuator is prevented from rotating about the axis and a releasing position in which the lock actuator is permitted to rotate about the axis, an electric circuit having a token reader, and an electromagnetic actuator, the electromagnetic actuator having a shaft that is movable parallel with the axis between a first position in which the blocker is locked in the locking position and a second position in which the blocker is movable from the locking position to the releasing position, the electric circuit being configured to signal the electromagnetic actuator to move the shaft from the first position to the second position if the token reader reads a valid access code, the lock core further having a blocker spring that engages the blocker and biases the blocker toward the locking position when the blocker is in the releasing position, a long dimension of the blocker being perpendicular to the axis; and a token that is couplable mechanically to the lock actuator, the token having an access code that is read by the token reader when the token is coupled mechanically to the lock actuator, the electric circuit signaling the electromagnetic actuator to move the shaft parallel with the axis from the first position to the second position so that the blocker is movable perpendicular to the axis from the locking position to the releasing position if the access code read by the token reader matches the valid access code.
