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