Lock device (1) which incorporates a closure assembly (2) that can move between an open position and a closed position, a locking device to lock said closure assembly (2) in the closed position, a first actuator (3, 31) and a second actuator (4, 41), both the first actuator (3, 31) and the second actuator (4, 41) having a locked position, in which a locking or retention action is applied, and an unlocked position, both the first and the second actuators having respective control devices which allow orders to be given to change the position of each respective actuator, wherein the first actuator and the second actuator are arranged in such a way that unlocking the locking device requires that both control devices place their respective actuator in the unlocked position.

An electronic cabinet lock includes a lock housing, a lock body, a limiting member, a motor, and a main control board. The lock body and the limiting member are rotatably disposed in the lock housing, respectively. The motor is electrically connected to the main control board. The limiting member is driven by the motor through a transmission mechanism. The transmission mechanism includes a screw rod driven by the motor and a slider threadedly connected to the screw rod. The slider is slidably disposed in the lock housing, and is movably connected to the limiting member. The transmission mechanism has few components, which is a simple structure and convenient for assembly.

Latch assemblies and systems are disclosed. One latch includes a latch and a receiver. The latch has a housing and a pin extending from the housing. The pin is mounted for longitudinal movement along a pin axis. The latch further includes a motor coupled to move the pin longitudinally. The receiver defines an aperture extending along a receiver axis and positioned to receive the pin of the latch. The receiver has a retainer biased toward the receiver axis. The latch assembly has an open position in which the pin is extended distally along the pin axis and received in the aperture, and a latched position in which the pin is retracted proximally along the pin axis while the retainer is engaged with the pin. One latch system includes a plurality of latch assemblies configured to move to the latched position after all latch assemblies are in the open position.

The present invention relates to a door lock system (10) for an appliance, in particular for a domestic appliance, preferably for a cooking oven. The door lock system (10) comprises a hook element (14) pivotable around a pivot axis between an unlocked released state and a locked released state and movable along a main axis perpendicular to said pivot axis between the locked released state and locked pulled state. The door lock system (10) comprises a first sliding member (18) movable along the main axis and provided for pivoting the hook element (14) to the locked released state. The door lock system (10) comprises at least one further sliding member (20, 22) movable along the main axis and provided for pulling the hook element (14) to the locked pulled state.

This application is directed to systems and methods of locking and unlocking a hatch lid or any other type of opening having a hinged covering. In some embodiments, a blade is actuated by a motor or linear actuator. Blades of the inventive subject matter can include one or two racks that interact with one or two pinion gears. In embodiments having rotational motors, a pinion gear can be coupled with that motor and with a rack that can cause the blade to move when the motor turns. In embodiments having linear actuators, the linear actuator more directly causes the blade to move. Other embodiments of the inventive subject matter include a screw mechanism that can interact with a locker receptacle upon rotating a motor coupled thereto.

The inventive subject matter of this application is directed to system and methods that bring about the opening and closing of hatches, doors, windows, or other hinged openings. Embodiments of the inventive subject matter feature one or more levers that are coupled with a motor or linear actuator. Upon activating a motor or linear actuator, a lever coupled thereto (e.g., by a linkage) rotates, taking the system from a locked configuration to an unlocked configurations. In some embodiments, continued actuation brings the system from a closed configuration to an open configuration.

Systems and methods described in this application are directed to hatch lid actuation systems. Actuation systems of the inventive subject matter are configured to effect the opening and closing of lids that are hingedly coupled with an opening. An embodiment featuring a rotational actuator, e.g., a motor, as well as an embodiment featuring a linear actuator are described. Embodiments having rotational actuators can additionally feature a gearbox. Embodiments of the inventive subject matter can also include sensor packages that can determine various hatch lid conditions (e.g., whether a lid is open, closed, wet, etc.).

In order to lock the door proceeding from the open position, a locking bar is brought into the locked position under tension of a spring element, in which locked position a closing force acting on the locking bar is determined by the spring element, and, in order to unlock the door, the locking bar is brought out of the locked position into an unlocked position with the aid of an actuating force that is not applied by the spring element, and, after the striker has moved out of the locked position, the locking bar moves into the open position by the force of the spring element.

An electronic door system is disclosed for a door that selectively closes a door opening of a building structure. The electronic door system includes two or more of a gyroscope that senses angular velocity of the door, an accelerometer that senses acceleration of the door, a capacitive sensor that capacitively senses the building structure, or a microphone that senses sound of the door. The electronic door system also includes a controller that assesses a physical position of the door according to the two or more of the gyroscope, the accelerometer, the capacitive sensor, or the microphone.
