An electrically operated actuator (12, 112, 212, 312) automatically operates dead-bolt assemblies and other locks, while preserving manual operation of the locks. The actuator assembly has rotating means for rotation of the drive bar (18), which in turn extends or retracts the bolt (14) of the lock.

An electrically operated actuator (12, 112, 212, 312) automatically operates dead-bolt assemblies and other locks, while preserving manual operation of the locks. The actuator assembly has rotating means for rotation of the drive bar (18), which in turn extends or retracts the bolt (14) of the lock. The rotating means may be a lever (28, 128, 238, 328, 438) attached to the drive bar (18) that is pivotable about the axis of rotation of the drive bar (18). The actuator assembly has driving means that forces the rotating means to rotate. The driving means is responsive to an electrical signal, which, for example, may be initiated from a remote-controlled transmitter (502, 602). The driving means may include a motor (20, 120, 220) for rotating a rod (22, 122, 222, 322) that in turn operates an assembly that rotates or drives the rotating means. In response to an electrical signal, the driving means actuates the rotating means to affect either a locking or unlocking operation, which operations are always completed by placing the actuator assembly in a state whereby the bolt of the lock may subsequently be extended or retracted manually, or automatically by the driving means.

[ What is claimed is:] [1.] An electrically operated actuator in combination with a dead bolt assembly, the dead bolt assembly comprising a lock having a drive bar and a bolt, the bolt being operably coupled to the drive bar such that rotation of the drive bar extends and retracts the bolt linearly, the actuator comprising:a lever that extends and retracts the bolt linearly, the lever being attached to the drive bar at one end and being unattached at another end opposite the attached one end, said lever having an axis of rotation that is coaxial with an axis of rotation of the drive bar, said lever being pivotal from a first position wherein the bolt is retracted to a second position wherein the bolt is extended;a motor capable of rotating a threaded rod attached thereto in a clockwise and counterclockwise direction, said motor being responsive to an electrical signal;an actuating arm screwed onto said threaded rod having a first protrusion on one end of said arm and a second protrusion on an opposite end of said arm, said arm having means to prevent rotation of said arm about said threaded rod;said actuating arm being positioned on said threaded rod such that said first protrusion is capable of contacting said lever at a first contact point and pivoting said lever to said first position and said second protrusion is capable of contacting said lever at a second contact point and pivoting said lever to said second position, wherein said first contact point is different from said second contact point.
