ELECTROMECHANICAL LOCK CYLINDER
An electromechanical lock cylinder. The cylinder includes a core front end, a core back end coupled with a tailpiece, an actuator mechanism, switchable between a locked state and an unlocked state, to keep the core front end uncoupled with the core back end in the locked state, to couple the core front end with the core back end in the unlocked state to enable the core front end to rotate the core back end from a locked rear position to an unlocked rear position, and to return to keep the core front end uncoupled with the core back end in the locked state; an enforced coupling to couple the core front end with the core back end as the core front end starts to rotate the core back end away from the locked rear position in the unlocked state, and decouple the core front end from the core back end as the core back end returns to the locked rear position; an operation knob, coupled with the core front end, to enable a user to rotate the operation knob from an initial knob position so that the core front end rotates the core back end from the locked rear position to the unlocked rear position in the unlocked state; and a return force mechanism to rotate the operation knob further after the user first has rotated the operation knob away from the initial knob position and then released the operation knob, whereby the core back end is rotated to the locked rear position by the core front end due to the coupled enforced coupling.
