Electrically controlled locking arrangement

An electrically-controlled locking arrangement for a lock mechanism of a commercial vehicle load space door, the lock mechanism including a housing, a hook member rotatably mounted within the housing and projecting from the housing for engaging an external catch member, a handle coupled to the hook member to effect movement thereof between open and closed positions, a detent provided on one of the hook member and a hub coupled thereto, a locking dog mounted within the housing for movement between a locked setting where the dog is in engagement with the detent and a free setting where the dog is not engaged with the detent and the handle is operable to move the hook member to its open position, and an electric actuator mounted within the housing and arranged to drive the locking dog to its free setting so allowing rotation of the hook member from its closed position to its open position, wherein the locking dog is mounted within the housing for rotation between said locked and free settings, and wherein the locking dog is in the form of a first order lever having first and second arms to each side of a pivot for the first order lever, a free end of the first arm being engageable in the detent thereby to block movement of the handle and hook member from said closed position and the electric actuator is supported adjacent the second arm, for driving the locking dog to said free setting.
