  • Patent number: 8590948
    Abstract: An outer operational device includes a cover mounted to an outer side of a door. The outer operational device includes a handle and an actuating member operatively connected between the handle and a latch. A sliding block is movable between an alignment position and an alignment position under control of a driving device through electrification. When the sliding block is in the engagement position, a locking block locks the actuating member to prevent rotation of the handle, and the outer operational device is in a locked state avoiding retraction of the latch. When the sliding block is in the disengagement position, the sliding block allows rotation of the actuating member and the handle, and the outer operational device is in an unlocked state allowing retraction of the latch.
