Manual electronic deadbolt

A method for operating an electronically-controlled, manually-actuated lock, comprising:

• in response to receiving a valid user credential input, actuating a motor via a control circuit to rotate an actuating spindle around a first axis, the actuating spindle comprising a driving pin that engages a transmission spring to move the transmission spring along the first axis from a neutral position to a biasing position, wherein:
• movement of the transmission spring to the biasing position biases a movable flange from a first position to a second position;
• biasing the flange to the second position compresses an actuator spring, which pushes a pin toward an engaged position, and
• in the engaged position, the pin engages a bezel assembly and a coupling rotatably coupled to a torque blade that is further drivably coupled to a latch bolt;
• and
• in response to receiving a manual rotation of a bezel included in the bezel assembly around a second axis, rotating the torque blade around the second axis and driving the latch bolt to a locked position or an unlocked position.

A locking assembly for use on a door separating an exterior space from a secured space, comprising:

• an electronic actuating mechanism comprising a motor for actuating an engagement mechanism to drivably couple a bezel assembly to a latch assembly via a coupling mechanism;
• the engagement mechanism comprising:
• an actuating spindle including a driving pin, wherein:
• the actuating spindle is positioned to rotate around a first axis in response to actuation of the motor;
• and
• upon rotation of the actuating spindle, the driving pin is configured to engage a transmission spring and bias the transmission spring relative to the driving pin along the first axis between a neutral position and a biasing position;
• and
• a flange engageable by the transmission spring at least when the transmission spring is in the biasing position, the flange being movable between a first position and a second position, wherein the flange is biased toward the second position when the transmission spring is in the biasing position;
• the coupling mechanism, comprising:
• an actuator spring engageable by the flange, wherein the actuator spring is decompressed when the flange is in the first position and compressed when the flange is biased toward the second position;
• a pin engageable by the actuator spring and movable between a disengaged position and an engaged position;
• wherein the pin is moved to the engaged position when the actuator spring is compressed;
• and
• a coupling drivably coupled to the latch assembly and within which a recess is defined and dimensioned to receive the pin, wherein the coupling receives the pin when the pin is in the engaged position;
• the bezel assembly, comprising:
• a bezel positioned to rotate around a second axis;
• and
• a sleeve rotatably coupled to the bezel and within which a bore is defined that is operatively engageable by the pin;
• wherein:
• when the pin is in the engaged position, the pin partially resides within and extends through the bore and is received in the recess defined in the coupling;
• and
• when the pin is in the disengaged position, the pin is disengaged from the coupling;
• and
• the latch assembly, comprising:
• a latch bolt movable between a locked position and an unlocked position;
• a latch spindle configured to drive movement of the latch bolt between the locked position and the unlocked position;
• and
• a torque blade rotatably coupled to the coupling and drivably coupled to the latch spindle,
• wherein when the pin is in the engaged position, manual rotation of the bezel around the second axis rotates the torque blade around the second axis and causes the latch spindle to drive movement of the latch bolt from the locked position to the unlocked position or from the unlocked position to the locked position.
