Abstract
Mechanically or electromechanically positioning a deadbolt used to lock or unlock a door is disclosed. An electromechanical lock can include a deadbolt to be positioned to lock or unlock a door. The deadbolt can be mechanically positioned based on the rotation of a paddle of the electromechanical lock or electromechanically positioned via a motor being turned on to position the deadbolt. A disengagement mechanism can disengage an engagement cog from a worm gear hub of a gear train of the motor upon the mechanical positioning, but remain engaged upon the electromechanical positioning.
Claims20
An electromechanical smart lock configured for wireless communication with a smartphone to lock and unlock a door of a home, the electromechanical smart lock installed within the door, comprising:
- a deadbolt configured to be positioned to lock or unlock the door;
- a paddle configured to rotate to position the deadbolt in a mechanical mode of operation for the electromechanical smart lock;
- a motor configured to position the deadbolt in an electromechanical mode of operation for the electromechanical smart lock, the motor turned on to position the deadbolt upon an instruction provided by the smartphone;
- and
- a disengagement gear assembly having an engagement cog, a worm gear hub and a release cam, the worm gear hub being part of a gear train of the motor, the disengagement gear assembly configured to disengage the engagement cog from the worm gear hub upon rotation of the paddle to position the deadbolt by retracting engagement teeth of the engagement cog away from the worm gear hub, the disengagement gear assembly configured to maintain engagement of the engagement cog with the worm gear hub upon use of the motor to position the deadbolt, wherein the release cam is coupled with the engagement cog and a rotation of the release cam causes the engagement cog to rotate for engaging or disengaging with the worm gear hub, wherein maintaining engagement of the engagement cog with the worm gear hub includes the engagement teeth of the engagement cog disposed in pockets included between engagement teeth of the worm gear hub.
An apparatus comprising:
- a deadbolt configured to be positioned to lock or unlock a door;
- and
- a disengagement gear assembly having an engagement cog, a release cam and a gear train of a motor, the disengagement gear assembly configured to mechanically position the deadbolt by disengaging the engagement cog from the gear train of the motor by decoupling teeth of the engagement cog from teeth of the gear train, and configured to electromechanically position the deadbolt by engaging the engagement cog with the gear train of the motor by coupling the teeth of the engagement cog with teeth of the gear train, wherein the release cam is coupled with the engagement cog and a rotation of the release cam causes the engagement cog to rotate to engage or disengage with the gear train, wherein maintaining engagement of the engagement cog with the gear train includes the engagement teeth of the engagement cog disposed in pockets included between engagement teeth of the gear train.
An apparatus comprising:
- a deadbolt configured to be positioned to lock or unlock a door;
- and
- a disengagement gear assembly having an engagement cog, a release cam and a gear train of a motor, the disengagement gear assembly configured to receive a first amount of force to apply to the engagement cog to mechanically position the deadbolt, and configured to receive a second amount of force to apply to the engagement cog to electromechanically position the deadbolt, the first amount of force being higher than the second amount of force, wherein the release cam is coupled with the engagement cog and a rotation of the release cam causes the engagement cog to rotate to engage or disengage with the gear train, wherein maintaining engagement of the engagement cog with the gear train includes engagement teeth of the engagement cog disposed in pockets included between engagement teeth of the gear train.
