  • Publication number: 20090173120
    Abstract: An electric door lock includes a rotatable member, a driving unit, and a manual operating member. The rotatable member is rotatable in first and second rotational directions and is provided with a first protrusion. The driving unit is coupled to the rotatable member, and operable so as to drive rotation of the rotatable member. The manual operating member is rotatable between locking and unlocking positions and is provided with a second protrusion. The first protrusion pushes the second protrusion to permit rotation of the manual operating member between the locking and unlocking positions when the rotatable member is driven by the driving unit to rotate in the first and second rotational directions, respectively. The second protrusion slides over the first protrusion when the manual operating member is driven to rotate between the locking and unlocking positions and when the driving unit is deactivated.

  • Publication number: 20090173114
    Abstract: An electric door lock includes a driving module and a control module. The driving module is operable between locking and unlocking modes. The control module includes a switch unit and a manual operating member. The switch unit is operable so as to deactivate the driving module when actuated. The manual operating member includes a shaft that extends rotatably into the lock housing, that has an actuating protrusion, and that is rotatable relative to the lock housing between locking and unlocking positions. When the driving module is operated in the locking mode, the shaft of the manual operating member is disposed at the locking position and the actuating protrusion actuates the switch unit. When the driving module is operated in the unlocking mode, the shaft of the manual operating member is disposed at the unlocking position and the actuating protrusion actuates the switch unit.
