Designed to open up and close home windows in difficult to reach areas, electric window openers, or actuators, are exceptionally handy.
They work via a motorised folding arm that is attached to a window. The arm starts in a folded position, however since it is driven by the motor, it starts to unfold. The arm is positioned in a manner that as it begins to unfold, the windowpane begins to open. To close a windows, the arm begins to fold back up into its unique position, bringing the screen to a close.
It really is simple in framework, easy to install, simply gently drive the rack in the sliding door handle on the door frame, the door could be easily opened.
The opening mechanism for a rack and pinion works by converting rotational motion into linear motion. The pinion can be a circular gear, which engages a linear bar that has been fitted with teeth, known as the rack; power is certainly applied to the pinion leading to it to rotate, which subsequently makes the rack move around in relation to the pinion, which converts the rotational movement of the pinion into linear motion. For electric window openers, the rack is housed in exterior casing and is attached to the windows. As the pinion moves, the rack is definitely pushed out, opening the screen along with it.
These are usually fitted to side hung home windows or doors, because they provide a 90-degree opening. Also, they are called folding arm actuators and may be designed to open up inwards, outwards or both methods.
The Automatic Window Opening System gear rack object of today’s invention is achieved, through the guts gear 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 might be engaged with the stationary gear rack, the slide rack when the pushing manage on the entranceway, so that the rotation from the apparatus rack fixed on the door, 
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 device with a special dual rack door when the sliding door.
