Abstract:
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:means for rotating the drive bar to extend and retract the bolt;means for driving said rotating means, said driving means being responsive to an electrical signal;wherein said electrical signal is generated by:a wireless transmitter that transmits a request to actuate the actuator;a wireless receiver that receives the request to actuate the actuator; anda control circuit, operably connected to said wireless receiver, the control circuit providing said electrical signal to said driving means if the request is valid; andwherein said rotating means comprises:a resilient lever attached to the drive bar, said resilient lever being pivotal about an axis that is coaxial to an axis of rotation of the drive bar; andwherein said driving means comprises:a motor capable of rotating a threaded rod that extends from said motor;a threaded member screwed onto said threaded rod;a guide preventing rotation of said threaded member; andsaid threaded member being adapted to frictionally engage and to rotate said resilient lever.
