Method for retrofitting a deadbolt assembly with an electrically operated actuator
First Claim
1. A method for retrofitting an existing lock with an electrically operated actuator, the lock having an interior cylinder or knob, an exterior cylinder, a drive bar, a bolt and existing mounting hardware, the method comprising the steps of:
- (a) removing the interior cylinder or knob;
(b) placing a support plate having an at least one opening formed therein and a preassembled actuator mounted thereon on a door such that the at least one opening receives existing mounting hardware from the exterior cylinder; and
(c) coupling a drive bar attachment to the drive bar.

Abstract
A method is provided for retrofitting an existing dead-bolt assembly with an electrically operated actuator (12, 112, 212, 312, 800). The electrically operated actuator automatically operates the dead-bolt assembly while preserving manual operation of the lock. 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, 818) 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.
