For the purpose of improving properties regarding construction a home appliance device, in particular a home chiller appliance device, is proposed. The device has at least one main body defining at least one storage space; at least one door mounted to the main body and featuring at least one sealed door section that forms at least a portion of a front wall of the storage space; and at least one protrusion unit arranged next to the sealed door section outside the storage space and protruding from the door towards the main body.

A resin back door for a vehicle includes a resin inner panel, a resin lower outer panel, a metal left reinforcing member, and a damper stay bracket. The metal left reinforcing member is disposed in a hollow space defined by the inner panel and the lower outer panel, and is fixed to the inner panel with an adhesive leaving a gap. The damper stay bracket is attached on an outer side of the inner panel in a vehicle width direction. In the resin back door for a vehicle, the damper stay bracket is fastened to the left reinforcing member across a collar having one end inserted into a hole provided in the inner panel.

An apparatus according to one embodiment includes a door closer having a pinion adapted to be operably coupled to a door and rotate in a first direction in response to opening the door and to rotate in a second direction in response to closing the door, and a power boost module operably coupled to the pinion. The power boost module includes a motor adapted to generate electrical energy via rotational movement of the pinion and supply a boost force to the pinion to assist closing the door, a gearing operably coupled to the pinion and the motor and structured to back drive the motor to generate the electrical energy in response to rotation of the pinion, and an energy storage device adapted to store the electrical energy generated by the motor and supply stored electrical energy to the motor for the boost force.

Provided is a swing door operator (110) for moving a door leaf (120) between a first position and a second position. The swing door operator (110) is arranged to operate in a powered and a powerless mode and comprises a permanent magnet DC motor (310). The motor (310) is arranged to move the door leaf (120) at least from the second position to the first position in the powered mode. The swing door operator (110) further comprises a mechanical drive unit (320), arranged to move the door leaf from the first position to the second position in the powerless mode. In the powerless mode, at least one resistive device is electrically connected in parallel with the motor (310) and arranged to limit a current generated by the motor (310) in response to the movement of the door leaf (120) from the first position to the second position by means of the mechanical drive unit (320). A method for controlling the swing door operator is also provided.

A combination door operator assembly and door, wherein the door operator assembly includes an operator unit mounted to the door on the pushing side thereof, an arm linkage having a driving arm and a driven arm, a second mounting bracket preferably on the frame of the door, a rechargeable power storage pack having at least one of a rechargeable battery and one or more capacitors, and a controller, for monitoring a speed and a position of the door, wherein when the door moves faster than a predetermined speed, the motor is used as a generator to charge the rechargeable power storage pack and the speed of the door is reduced.

A movable wall system includes a plurality of movable wall panels including a first movable wall panel and a second moveable wall panel rotatably coupled together through at least one hinge. The movable wall system further includes a biasing system which biases the first movable wall panel and the second movable wall panel into an arrangement wherein a panel face of the first movable wall panel and a panel face of the second moveable wall panel are generally parallel.

A drive for a leaf of a door, window, or the like, comprising at least one mechanical energy store, which is charged by an opening movement of the leaf and discharged by a closing movement of the leaf, at least one electric motor, which is operatively connected to the leaf via at least one motor shaft and can be operated as a generator in order to dampen the leaf movements, and a control and/or regulator electronics unit for controlling the electric motor. The control and/or regulator electronics unit comprises means via which the drive behaviour can be variably specified repeatedly by a respective user and/or via which the drive behaviour can be variably adjusted repeatedly in accordance with the behaviour of a respective user.

A combination door operator assembly and door, wherein the door operator assembly includes an operator unit mounted to the door on the pushing side thereof, an arm linkage having a driving arm and a driven arm, a mounting bracket on the frame of the door, a rechargeable power storage pack having at least one of a rechargeable battery and one or more capacitors, and a controller for monitoring a speed and a position of the door, wherein when the door moves faster than a predetermined speed, the motor is used as a generator to charge the rechargeable power storage pack and the speed of the door is reduced.

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.
