  • Patent number: 7549685
    Abstract: A lock for a household appliance, such as a tumble drier, a washing machine, a dishwasher or the like, has a movable retaining element. The movable retaining element is configured in the style of a slider for interaction with a locking bar located on a door, a lid, a hinged opening or the like of the household appliance. The lock has a two-state locking mechanism for the retaining element, such that the locking mechanism in a first state blocks the movement of the retaining element and in a second state frees the movement of the retaining element. The locking mechanism can be electromagnetically controlled between the two states.

  • Publication number: 20090133453
    Abstract: An electric steering lock for a drive authorization system in a motor vehicle, including a movable locking element which, according to a first position, can be brought into locking engagement with a latched-in position on the steering shaft in the steering wheel column and, according to a second position, can be brought out of locking engagement with said position. The steering lock also has a drive for moving the locking element between the two positions, and electronics for controlling the drive. The system may have an associated second device in the form of an electronic key, an identification (ID) transmitter, a chip card or the like, with the result that, when the second device is authorized, the drive can be controlled into the respective position by the electronics. The electronics generate those signals which are used to trigger functions which can otherwise be effected by an electric ignition lock.

  • Publication number: 20080185849
    Abstract: The invention relates to a closing mechanism for a mobile closing element, especially for a door, a cover, a flap or the like on a household appliance, such as a dishwasher machine, a washing machine, a refrigerator or the like, said mechanism comprising a carriage that can be displaced between a locking position and an unlocking position and is loaded by means of a spring in the direction of the locking position. The carriage carries a closing hook that can be engaged with the closing element for the closing action and/or disengaged therefrom for the opening action. A rotary latch can co-operate with the closing element during the closing action. As a result of this co-operation, said rotary latch acts on the carriage in such a way that the carriage is displaced into the locking position during the closing of the closing element by the force of the spring.

  • Publication number: 20080173798
    Abstract: A process and a device are provided-for ascertaining the rotation of a liquid spray arm for a domestic appliance. Lighting means serves as a light transmitter and a photoreceiver serves as a light receiver. The lighting means and the photoreceiver are assigned a light-conducting element. At a first location of the light-conducting element, at least some light emitted from the lighting means is coupled to a path so that the light is guided in the light-conducting element by total reflection. At a second location of the light-conducting element that spaced apart from the first location in the direction of propagation of the light, the light guided in the light-conducting element is coupled out of the path so that the light is received by the photoreceiver. The intensity of the light received by the photoreceiver is evaluated by an evaluation circuit with respect to the rotation of the spray arm.

  • Publication number: 20080100066
    Abstract: The invention relates to a lock, in particular for a household appliance such as a tumble drier, a washing machine, a dishwasher or the like, having a movable retaining element, which is configured in particular in the manner of a slide. The retaining element interacts with a closure hook located on a closure element, such as a door, a cover, a flap or the like of the household appliance, which can be moved between an open and a closed state. The closure hook, in the closed state of the closure element, engages into the retaining element. Here, the closure hook is held by the retaining element in contact against a blocking face in such a way that a movement of the closure element into the open state is blocked. The blocking face is designed so as to be pivotable in the manner of a positive opener.
