Patent ID: 8468861

Claim:
An electromechanical lock, comprising: an electric generator configured to generate electric power from mechanical power; an electronic circuit, powered by the electric power, configured to read data from an external source, and match the data against a predetermined criterion; an actuator, powered by the electric power, configured to set the electromechanical lock from a locked state to a mechanically openable state; a lock cylinder; and a key follower, powered by the mechanical power, configured to organize timing of the electromechanical lock in relation to a movement of a key as follows: during a first insertion phase and a second insertion phase, convey the mechanical power to the electric generator and mechanically enable operation of the actuator; and during a removal phase of the key, return to a starting position and mechanically reset the actuator to the locked state, wherein the key follower comprises: a first claw configured to engage with the key during the first insertion phase; and a second claw configured to engage with the key during the second insertion phase, and further configured to protrude from an inner wall of the lock cylinder when the key is fully inserted in the lock cylinder so that during the removal phase of the key the second claw contacts with the key and the key rotates the key follower to the starting position with mechanical power only, and wherein the actuator further comprises a support configured to, during the first insertion phase and the second insertion phase, by the generated electric power, move to a fulcrum position in order to set the lock mechanically from the locked state to the mechanically openable state, and configured to, during the removal phase of the key, by mechanical power, reset the actuator to the locked state.
