Designed to open and close home windows in difficult to reach areas, electric home window openers, or actuators, are exceptionally handy.
They work via a motorised folding arm that is attached to a home window. The arm begins in a folded placement, however since it is run by 
the electric motor, it begins to unfold. The arm is positioned in a manner that as it starts to unfold, the screen begins to open. To close a screen, the arm begins to fold back again up into its unique position, bringing the windowpane to a close.
It is simple in structure, easy to install, simply gently drive the rack in the sliding door deal with on the door frame, the door could be easily opened.
The opening mechanism for a rack and pinion works by converting rotational movement into linear movement. The pinion can be a circular gear, which engages a linear bar that is fitted with teeth, known as the rack; power is certainly applied to the pinion causing it to rotate, which subsequently makes the rack move in regards to the pinion, which converts the rotational movement of the pinion into linear movement. For electric windows openers, the rack is usually housed in exterior casing and is mounted on the home window. As the pinion moves, the rack is definitely pushed out, starting the windows along with it.
These are usually suited to side hung windows or doors, as they provide a 90-degree opening. They are also called folding arm actuators and can be designed to open inwards, outwards or both methods.
The object of the present invention is achieved, Automatic Window Opening System gear rack through the guts equipment shaft fixed on a frame, which is fixed to the frame, is fixed to the sliding equipment engages with the rack on the rail of the frame, fixed to the corresponding door there could be engaged with the stationary equipment rack, the slide rack when the pushing handle on the entranceway, to ensure that the rotation from the apparatus rack fixed on the entranceway, the door motion, so that the entranceway is opened, with a equipment fixed to the frame reset spring.
The object of the present invention is to supply a device with a special double rack door when the sliding door.
