The present disclosure relates to a bi-directional overrunning clutch, electronic door locks having bi-directional overrunning clutches, and methods of using the same. In certain embodiments, the electronic door lock includes a first locking mechanism for driving an inner wheel through a first torque to rotate a rotatable shaft to operate a locking device on a door by a user from outside, a second locking mechanism for driving inner wheel through the first torque to operate the locking device from an inside, a third locking mechanism for driving an outer wheel rotatable coaxially around the rotatable shaft through a second torque to operate the locking device electronically, and the bi-directional overrunning clutch. When outer wheel rotates at second torque, inner wheel and rotatable shaft rotate along with outer wheel, and when inner wheel rotates at first torque, outer wheel does not rotate along with inner wheel and rotatable shaft.

Disclosed is a household appliance comprising: a door; a door lock unit equipped with a hook part which is configured to unlock and open the door by moving outward; a motor configured to generate torque by using electricity; a driving gear unit which has a rotary shaft at one end portion and is configured to rotate by receiving the torque from the motor, wherein the one end portion pushes the hook unit to the outside of the door lock unit to open the door when the driving gear unit rotates in one direction; a sensing unit configured to sense the displacement of the other end portion of the driving gear unit when the hook unit moves to the inside of the door lock unit, wherein the other end portion rotates in the opposite direction about the rotary shaft of the driving gear unit; and a control unit configured to control the operation of the motor on the basis of the displacement, sensed by the sensing unit, of the other end of the driving gear unit.

An electronic lock includes a deadbolt, a driver mechanism, a transmission mechanism and a control mechanism. The transmission mechanism includes a transmission gear that is driven by the driver mechanism to rotate, a resilient unit that is mounted to and co-rotatable with the transmission gear, and a rotary member that is operable to rotate relative to the transmission gear between a locking position and an unlocking position, and that is connected to the deadbolt. The control mechanism is connected to the rotary member, and ceases operation of the driver mechanism when detecting that the rotary member has been rotated to one of the locking and unlocking positions.

An exemplary method includes operating an access control device including a bolt, an output gear having a magnet mounted thereon, a first magnetic sensor, and a second magnetic sensor. The method generally includes selectively determining a position of the output gear via one of the first magnetic sensor or the second magnetic sensor based upon a current handedness of the access control device. With the access control device in a first handing configuration, the first magnetic sensor may be used to a first handedness first home position of the output gear. With the access control device in a second handing configuration, the second magnetic sensor may be utilized to detect a second handedness first home position of the output gear

An electronic lockset assembly is configured to determine whether or not a door is open or closed before the lockset actuates a bolt. In one aspect, a wireless electronic lockset is disclosed. The wireless electronic lockset includes a processing unit, a bolt movable between a locked position and an unlocked position, a motor actuatable by the processing unit to move the bolt between the locked and unlocked positions, and a sensor communicatively connected to the processing unit and configured to detect air pressure. The processing unit is configured to execute instructions to receive, from the sensor, air pressure signals, and determine whether a door is closed based at least in part on a change in the air pressure reflected in the air pressure signals.

An electronic door lock includes a motor having a stator and a rotor that rotates relative to the stator. The rotor is configured to rotate a spindle operatively coupled to a deadbolt lock at a 1:1 drive ratio therewith. The spindle is engaged with the deadbolt lock to cause extension and retraction with rotation of the spindle

The present disclosure provides a lock with a clutch driving mechanism, comprising a driving input portion, a dutch component, a dead bolt driving component, a latch bolt driving component, a first end of the driving input portion is driven, and the second end is connected to the clutch component; a first end of the dutch component is driven, a second end drive one of the dead bolt driving component and the latch bolt driving component, a first end of the latch bolt driving component is driven in the second direction, a second end opens the door. The mechanism can simply realize the keyless mechanical double locking of the dead bolt while the latch bolt still remains in the normally open mode without using the key every time when locking the dead bolt, that key or motor drive is used only when the dead bolt double locking is to be released.

A fenestration assembly including a panel, a lock assembly coupled to the panel, and an actuation system coupled to the lock assembly. The lock assembly includes a motor, a transmission driven by the motor, a sensing assembly, and a slide assembly that includes a rack member operatively coupled to the motor by the transmission and a drive bracket member that is slidable by the rack member between a locked drive bracket member position and an unlocked drive bracket member position.

Locking devices, systems, and methods for securing personal property to separate structures. Such a locking device includes a lock body, a cable within the lock body and having a first end accessible from an exterior of the lock body, a spool for extending and retracting the cable out of and into the lock body, a lock pin disposed at the first end of the cable, a cable lock incorporated into the lock body and configured to releasably secure the lock pin to the lock body, and an electronic communication and control unit incorporated into the lock body and configured to communicate with a remote device. The electronic communication and control unit controls the cable lock to secure and release the lock pin relative to the lock body to allow the remote device to wirelessly unlock the first end of the cable from the lock body.
