Rotary lock actuator

An actuator assembly for manual or powered actuation of a lock mechanism of the type having a lock plug and a locking member, the actuator assembly comprising:

• a housing for mounting a motor and a powered drive train engaged with the motor;
• a manual drive member mounted for movement between forward and reverse positions, the lock plug being connectable to the manual drive member;
• a powered drive member being mounted in the housing for movement between forward and reverse positions, the powered drive train being connectable to the powered drive member;
• said drive members each having first and second drive surfaces spaced apart from one another;
• an actuating member operable to move said locking member between first and second positions;
• and
• each of the spaces intermediate the first and second drive surfaces of each drive member having disposed therein at least one drive finger, the drive finger being operatively related to the actuating member such that selective rotation of one of said drive members moves the actuating member and connected locking member between first and second positions.

An actuator assembly for manual or powered actuation of a lock mechanism of the type having a locking member and a lock structure including lock plug, a lock body with at least first and second channels spaced 90° apart, and tumblers engageable with the first and second channels, the actuator assembly comprising:

• a housing for mounting a motor and a powered drive train engaged with the motor;
• a recess formed in the housing and having first and second stop faces spaced apart from one another;
• an actuating member connectable to the locking member and movable between first and second positions;
• a manual drive member connectable to the lock plug and having first and second drive surfaces spaced apart from one another, the manual drive member further including a lug disposed in said recess and movable between the stop faces, the manual drive member mounted for movement between neutral, forward and reverse positions, the stop faces being arranged to permit the lock plug to align the tumblers with the first channel but prevent the lock plug from rotating sufficiently to align the tumblers with the second channel;
• a powered drive member having first and second drive surfaces spaced apart from one another, the powered drive member being mounted in the housing for movement between neutral, forward and reverse positions, the powered drive train being connectable to the powered drive member;
• at least one drive finger disposed intermediate the spaces between the first and second drive surfaces of each drive member, the drive finger being engageable with the actuating member and being engageable by the first driving surface of each drive member for moving the actuating member from said first position toward said second position upon movement of one of the drive members toward the forward position, the drive finger being engageable by the second driving surface of each drive member for moving the actuating member from said second position toward said first position upon movement one of the drive members toward the reverse position;
• and
• a bi-stable spring connected to the housing and the actuating member to bias the actuating member to one of said first or second positions, whereby the bi-stable spring will complete the driving of the actuating member from one position to the other as begun by a drive member.
