An application, in particular for motor vehicle closing devices. The basic design of the motor vehicle has an electric motor and an actuating element which is acted upon by the electric motor directly or indirectly via a powertrain. The powertrain is provided with at least one Evoloid toothing. According to the invention, a drive shaft of the electric motor is equipped with an Evoloid pinion which meshes with an Evoloid output gear at the input of the powertrain, thereby directly producing the Evoloid toothing.

A double-doored lid apparatus includes: a box body; first and second doors; an opening/closing mechanism that opens and closes the first and second doors in conjunction with each other; a locking mechanism that locks the first and second doors in their closed states; an urging member that urges the first and second doors in an opening direction while the doors are locked by the locking mechanism; and a support member that transmits the urging force from the urging member to the first and second doors. The support member includes: a first support portion that supports one end portion of the urging member; and second and third support portions that start to come into contact with the first and second doors, respectively, before the doors reach a predetermined locking position during closing motions thereof, and that support the first and second doors when the doors are locked by the locking mechanism.

The invention relates to a planar spiral gearbox, in particular for use in a door system, comprising: a gear, in particular a scroll plate, having a planar side on which a spiral toothed arrangement is arranged having at least one tooth that has a spiral tooth progression; and a cylindrical gear, in particular a torus gear, that has an external toothed arrangement at its jacket surface, wherein the spiral toothed arrangement of the gear is in meshing engagement with the external toothed arrangement of the cylindrical gear, with the gear having at least one additional toothed arrangement section that is radially spaced apart from an axis of rotation of the gear and serves for engagement of a drive toothed arrangement.

Slide operator assemblies and components for fenestration units, as well as associated methods of manufacture and use thereof.

A door drive for a motor vehicle door or motor vehicle flap, which is provided with an electromotive drive, a transmission downstream of the drive, and a force-transmission element. The force-transmission element is operatively connected to a leaf of the motor vehicle door or motor vehicle flap. An output element of the transmission and the force-transmission element are coupled by a toothing with compensation for play. According to the invention, the output element and/or the force-transmission element are not only designed to be moveable for play compensation, but can also be permanently fixed after the compensation for play.

A worm drive apparatus includes a worm drive assembly having a worm engaged with a worm shaft and positioned within a housing; and a first gear engaged with the worm shaft; a worm wheel positioned within a channel created by the housing, the worm wheel engaged with a shaft extending through the channel; a friction assembly engaged with the worm wheel and the shaft, the friction assembly having a friction disk positioned adjacent to the worm wheel; a lock washer positioned adjacent to the friction disk; and a wave spring positioned adjacent to the lock washer; the friction assembly aids in preventing unwanted movement of the apparatus; and the worm wheel and first gear are to engage.

A resistance hinge includes a first hinge bracket, a fixing shaft fastened in the first hinge bracket, a locating holder surrounding the fixing shaft, a friction part, a second hinge bracket and a transmission module. The friction part is formed in a hollow cylinder shape and surrounds the locating holder together with the fixing shaft. The second hinge bracket is pivotally mounted on the first hinge bracket. The transmission module is connected between the friction part and the second hinge bracket.

A furniture drive for moving a furniture part movably supported relative to a furniture carcass. The furniture drive includes a carrier to be fixed to the furniture carcass, an actuating arm pivotally supported relative to the carrier about a pivoting axis between a closed position and a maximum opening position, and an adjustment device configured to adjust a position of the maximum opening position of the at least one actuating arm. The adjustment device includes a pivoting member configured to be moved in at least two pivoting positions relative to the actuating arm, and the pivoting member is configured to distance the actuating arm in the at least two pivoting positions to a different extent from an abutment arranged on the carrier when the actuating arm is arranged in the maximum opening position.

A refrigerator and a control method thereof. The refrigerator includes a housing, a door configured to be rotatably coupled to the housing by including a hinge shaft and a hinge gear fixed to the hinge shaft, and a door opening and closing device provided at one end of the door to control opening and closing of the door. The door opening and closing device includes a drive motor, a final gear configured to receive power from the drive motor and transmit the power to the hinge shaft, the final gear arranged at one end of the door opening and closing device to interlock with the hinge gear, and a door position sensor arranged on one side of the final gear to detect a rotation angle of the final gear.

An electric apparatus and a control method thereof The electronic apparatus including a housing; a first door rotationally arranged on one side of the housing; a second door rotationally arranged on the other side of the housing; a first motor operationally connected to the first door; a second motor operationally connected to the second door; a first motor driver electrically connected to the first motor; a second motor driver electrically connected to the second motor; and a processor electrically connected to the first motor driver and the second motor driver, wherein the processor may control the first motor driver to drive the first motor to close the first door at a time different than a time the second door that is connected to the second motor driven by the second motor driver closes.
