Abstract:
1. An apparatus comprising: an auto dead bolt door device having a first side key entry and a back side having a user grappling member; a motor disposed internal to the device capable of providing torque useful in actuating a dead bolt of the auto dead bolt door device, the dead bolt having a retracted position, a dead position opposite the retracted position, and a plurality of extended positions between the retracted position and the dead position; and a gearing system that includes a plurality of toothed members having corresponding intermeshed gear teeth disposed between the motor and the dead bolt and operable to convey torque from the motor to actuate the dead bolt, wherein a first of the plurality of toothed members is coupled directly to the motor, the plurality of toothed members having a cooperative configuration that permits backdriven operation to allow torque to be applied to move the plurality of toothed members in a first direction and an opposite second direction such that an array of gear teeth of the first toothed member is configured to be a driven gear and a driving gear depending upon a torque applied, wherein the first toothed member coupled directly to the motor comprises a pinion gear.
