A furniture drive includes a carrier configured to be fixed to or within a furniture panel of a furniture carcass, an actuating arm assembly arranged on the carrier, a spring device for applying a force to the actuating arm assembly, an adjustment device for adjusting a force of the spring device to the actuating arm assembly, and a threaded section having a longitudinal direction. An engagement location of the spring device is adjustable along the threaded section by a rotation of an adjustment element about a rotational axis, and the rotational axis of the adjustment element and the longitudinal direction of the threaded section enclose an angle to one another. The angle formed by the rotational axis of the adjustment element and the longitudinal direction of the threaded section is configured to be varied upon a movement of the actuating arm.

A drive device for a movable furniture part includes a lockable push-out device for pushing the movable furniture part out of a closed position into an open position. The push-out device can be unlocked by virtue of the movable furniture part being pushed into an excess-pressure position located behind the closed position, as seen in the closing direction. An excess-pressure region is located between the closed position and an excess-pressure position. The drive device also has a damping device for damping the closing movement of the movable furniture part. The damping device has displacement-dependent damping, in which the damping force in a main damping region, located in front of the closed position—as seen in the opening direction, is higher than in the excess-pressure region.

Methods and systems include an actuator 40 adapted to provide drive power and hold power to an external device. A motor 34 provides for driving the external device to a determined position when the motor 34 is energized. A switching circuit is configured to energize the motor 34 with a high voltage to drive the external device to the determined position and energize the motor 34 with a low voltage to hold the external device in the determined position.

A door assembly for a vehicle includes a door and a check strap pivotally coupled to the door. An engagement member is releasably engageable with the check strap. A spring is positioned to bias the check strap toward the engagement member. When the engagement member is engaged with the check strap, the check strap maintains the door in an open position. When the engagement member is disengaged with the check strap, the door is swung to the closed position under the bias of the spring.

An automated door closure system regulate the release and closure of a door in a door assembly that includes a primary door, a secondary door, and a door frame. The system includes a door closer, a control unit, and an automatic input sensor. The door closer, which is connected between the secondary door and the door frame and includes a cylinder and an operating rod, biases the secondary door toward a closed position. The control unit includes a motive device and a rod catch element. The rod catch element, which may be moved by the motor, is positioned in proximity to the operating rod to adjustably prevent the secondary door from being closed. The automatic input sensor detects a door assembly use condition. The control unit controls the motive device based on the detected condition to move the rod catch element, allowing the door closer to close the secondary door.

The invention relates to an ejecting device for ejecting a cover element movably mounted on a piece of furniture, in particular a folding door or folding/sliding door, from a closed position into an open position. The cover element can be moved at least in one direction perpendicular to the closing plane, on which the cover element is arranged in the closed position, and in one direction parallel to the closing plane. The ejecting device comprises an energy accumulator, which is to be charged manually by a user, and an ejecting element, on which the energy accumulator acts, and the energy accumulator can be charged by moving the cover element substantially in a direction parallel to the closing plane, preferably during an ongoing cover element opening process following the ejection process, particularly preferably immediately following the ejection process.

One embodiment relates to a door operator including an operator body including a rotatable pinion, an arm connected to the pinion, an inductive sensor mounted adjacent the arm, and a controller in communication with the inductive sensor. The inductive sensor includes an inductor comprising a plurality of nested coils, and each of the coils is curved about the pinion. The controller is configured to provide the inductive sensor with a varying power signal, and the inductive sensor is configured to inductively link the inductor to the arm in response to the varying power signal. The inductive sensor has a characteristic which varies in response to the rotational position of the arm when the inductor is inductively linked with the arm. The controller is further configured receive information relating to the characteristic, and to determine the rotational position of the arm based upon the received information.

A control method includes controlling a lever, a pusher and a motor so as to arrange the same in a correct position when electric power is supplied to the home appliance, or the user turns on the home appliance. Abnormalities involving an automatic opening of the door through changes in a return/stop switch and an opening sensing switch while the motor operates so as to open the door may be confirmed.
