  • Patent number: 6840553
    Abstract: The present invention provides an apparatus for blocking and releasing a door lock of an electrical appliance, such as e.g. a washing machine, a dishwasher or a tumble drier. In said apparatus, use is made of a blocking and release unit, which in a blocking state blocks the locked door lock in order to prevent unlocking of the door lock. In a release state the blocking and release unit enables unlocking of the door lock in that it releases the still locked door lock. Furthermore, an emergency release unit, which is constructed separately from the blocking and release unit, is used to bring the blocking and release unit automatically into the release state in an abnormal operating state of the electrical appliance, such as e.g. in the event of a power failure.

  • Publication number: 20040061343
    Abstract: The electrically-operated door strike provides rapid and easy selection between fail-safe and fail-secure modes. A keeper is pivotably arranged in a housing. To prevent the keeper from pivoting, the keeper has at least one abutment, which a blocking surface or surfaces of a blocking element either contacts (door locked) or does not contact (door unlocked) when the keeper tries to pivot. The blocking element is movable by a solenoid, between a first (unenergized) position and a second (energized) position. The blocking element and solenoid are mounted in a holder, which in turn is slidably mounted in a housing, for movement between one of two holder positions, namely a fail-secure position and a fail-safe position. In the fail-secure position, the blocking surfaces are opposite the keeper's abutments in the unenergized position, and in the fail-safe position the blocking surfaces are opposite the keeper's abutments only when the actuator is energized.

  • Patent number: 6651387
    Abstract: A locking controller mounted inside a sliding door. The locking controller is operated in connection with an inner handle resiliently returned to a neutral position when being turned in a door opening direction or in a door closing direction. If the inner handle is pulled or pushed in the door opening direction in the state that the sliding door is closed, the inner handle is turned in the door opening direction from the neutral position to release a door-close maintaining mechanism. If the inner handle is pulled or pushed in the door closing direction in the state that the sliding door is open, the inner handle is turned in the door closing direction from the neutral position to release a door-open maintaining mechanism. Therefore, a simple operation that the inner handle is turned in one direction makes the opening or shutting of the sliding door possible.

  • Patent number: 6345848
    Abstract: The locking movement and/or the unlocking movement of a bimetallic drive of an electrothermally-controlled locking apparatus, for example for household-device doors, is or are driven by a separate bimetal member (10, 11) over only a first segment of its movement path. In the process, energy is supplied to the energy store (28) of a tipping over-center device until a dead-center position is attained, the energy being released as a moving drive for the remaining segment of the movement path when the dead-center position is exceeded, thereby cutting off the bimetal drive and stabilizing the locking member (2) in its end position.
