Abstract
A self-contained electric power driven bolt actuator unit for installation with a high security door locking mechanism comprising a housing adapted to be mounted on the door in operative association with the lock mechanism, a rotatable actuator shaft being mounted in the housing and connected at one end with a bolt actuating cam, an electric motor connected to drive the actuator shaft through a friction driving connection, a manually operable knob for overriding the actuation of the bolt by the cam independently of the motor, and switching means operable upon predetermined rotation of the actuator shaft in each direction of its rotation to reverse the driving direction of said electric motor and for indicating the operative position of the bolt of the locking mechanism.
Claims15
An electric power driven actuator unit for mounting on a hinged door frame in operative association with a lock mechanism having a bolt actuator supported for movements between bolt locking and bolt non-locking positions, comprising:
- (a) a housing adapted to be affixed to an exposed surface of the door frame;
- (b) adapter plug means carried by said housing, including a cam member adapted in the affixed position of said housing for operative association with the bolt actuator of said lock mechanism;
- (c) power actuating means in said housing having a driving connection with said cam member, and being selectively energizable to rotate said cam member in directions to move the bolt actuator to locking and non-locking positions;
- and
- (d) manual actuating means having an overriding connection for moving said cam in said directions independently of said power actuating means.
