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 friction based counterbalance mechanism for coupling with a closure panel to assist in opening and closing of the closure panel for at least a portion of a path between a fully closed position and a fully open position of the closure panel, the counterbalance mechanism including: an elongate member positioned on a longitudinal axis extending between the proximal and distal ends of the counterbalance mechanism, the elongate member having a peripheral surface, the elongate member having a proximal end for coupling to one of the closure panel and a body of a vehicle; a travel member having a body and at least one friction member mounted on the body, the travel member positioned on the longitudinal axis for reciprocation there along and for providing contact between the at least one friction member and the peripheral surface, said contact for generating a friction force in a first region along the longitudinal axis and in a second region along the longitudinal axis; and a support member coupled to the travel element at a proximal end and for coupling at a distal end to the other of the closure panel and a body of a vehicle, the support member for guiding said reciprocation. The friction based counterbalance mechanism can be incorporated as part of a biasing strut such as a spring configured strut.

A telescopic rod structure is provided. The telescopic rod structure includes a telescopic rod, a fixing piece and a movable piece, and the telescopic rod includes a sleeve and a piston rod sliding on the sleeve, driving the piston rod to slide in the sleeve so that the telescopic rod can be extended or shortened. The fixing piece and the movable piece are respectively hinged at the two ends of the telescopic rod, and the movable piece is hinged with the fixing piece, the three form a triangular structure, and the triangular structure can be switched between an unfolded first state and a folded second state. An adjustable box using the telescopic rod structure is also provided.

A lever pushes a latch drawn into a hook accommodating space in a latch holder in a direction where a door opens is installed in the latch holder, and the latch is released from the latch holder using the lever. The door that is opened by an initial opening angle by the latch holder releasing the latch automatically opens by self-weight of the door.

A door opening and closing device includes a motor which generates drive power for a door in an opening and closing direction of the door, a door position sensor which detects an opening and closing position of the door, and a controller which controls the motor based on the opening and closing position. The motor includes a stator having at least three-phase coils and a rotor. The motor generates the drive power when the rotor rotates with respect to the stator. The controller performs door holding control of generating, as the drive power, a holding force for holding the door at the opening and closing position, in a case where the opening and closing position is within a predetermined range. In the door holding control, the controller energizes at least two phases of the motor such that rotation of the rotor is braked to generate the holding force.

A sliding door closing device having an easy door opening function with an opening system. The closing device provides a slider with an attachment and gripper on one side of the device, and a properly shaped support of a moving roller on the other side of the device. A pusher contacts a roller support of the roller with a slider gripper and an opening spring and choke. The opening system allows for the opening of a door by pushing the door on vertical strip or on the edge.

A powered folding door or window system includes at least two rigid panels that are linked together by at least one vertical hinge/pivot to fold between a closed state, where the panels extend across an opening, to an open state, where they are retracted to one side of the opening and stacked against each other. The system incorporates a motor and a drive belt mechanism as primary means for driving the panels. The system further includes a powered actuator on one of the panels and a co-operative element on a linked adjoining panel; whereby the powered actuator cooperates with the co-operative element on the linked adjoining panel to move the linked adjoining panel and said one panel about the vertical hinge/pivot linking them; whereby the powered actuator may start the opening of the door or window system and/or complete the closing of the system.

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.

A line belt driven retrofittable door opener includes a motor, a drive link, an output link, and at least one flexible link. The at least one flexible link includes at least one flexible line link. The drive link is connected to the motor. The output link is connected to the arm of the door. The at least one flexible link interconnects the drive link with the output link. Wherein, the motor is configured for opening the door by rotating the drive link, which in turn rotates the output link via the at least one flexible link, which in turn rotates the arm, thereby opening the door.
