Abstract:
1. An exterior actuator assembly for a manually driven electronic deadbolt assembly and configured to operate a deadbolt mechanism from an exterior space via a torque blade, the exterior actuator assembly having a locked condition and an unlocked condition, the exterior actuator assembly comprising: a cylinder body; an exterior turnpiece rotatably mounted to the cylinder body; a torque blade driver coupled to the torque blade, the torque blade driver having a perimetrical lock recess, the torque blade driver being rotatable about a first rotational axis; a clutch assembly drivably interposed between the exterior turnpiece and the torque blade driver; a motor having a motor shaft arranged to rotate about a second rotational axis that is non-coaxial with the first rotational axis; wherein the first and second rotational axes are substantially parallel to each other; a locking shifter mounted to the cylinder body and configured for axial translation along the second rotational axis, the locking shifter having a blocking tab portion configured for selective engagement with the perimetrical lock recess of the torque blade driver; a rotational-to-linear motion converter drivably interposed between the motor shaft and the locking shifter and configured such that a rotation of the motor shaft in a first rotational direction about the second rotational axis results in an axial displacement of the locking shifter in a first longitudinal direction to a locked position corresponding to the locked condition wherein the blocking tab portion of the locking shifter is engaged with the perimetrical lock recess of the torque blade driver to prohibit rotation of the torque blade via the exterior turnpiece, and a rotation of the motor shaft in a second rotational direction about the second rotational axis results in an axial displacement of the locking shifter in a second longitudinal direction to an unlocked position corresponding to the unlocked condition wherein the blocking tab portion of the locking shifter is disengaged from the perimetrical lock recess of the torque blade driver to permit rotation of the torque blade via the exterior turnpiece; a turnpiece clutch shaft having a proximal end and a distal end, the exterior turnpiece being mounted to the turnpiece clutch shaft at the proximal end, and having an annular groove intermediate of the proximal end and the distal end, and having a pair of opposed V-shaped ramps spaced toward the distal end from the annular groove; a turnpiece clutch driver having a bore for receiving the turnpiece clutch shaft, the turnpiece clutch driver having a pair of opposed V-shaped slots configured to receive the pair of opposed V-shaped ramps of the turnpiece clutch shaft, the turnpiece clutch driver having a circumferential tab configured to drivably engage the torque blade driver; a retaining ring positioned in the annular groove; and a clutch spring interposed between the retaining ring and the turnpiece clutch driver, the clutch spring configured to bias the turnpiece clutch driver such that the pair of opposed V-shaped slots of turnpiece clutch driver engage the pair of opposed V-shaped ramps of the turnpiece clutch shaft.
