Designed to open up and close home windows in difficult to reach areas, electric screen openers, or actuators, are exceptionally handy.

They work with a motorised folding arm that is attached to a window. The arm starts in a folded placement, however as it is driven by the electric motor, it begins to unfold. The arm is positioned in a manner that as it starts to unfold, the home window begins to open. To close a screen, the arm begins to fold back up into its primary position, bringing the windowpane to a close.

It is simple in structure, easy to install, simply gently press 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 movement. The pinion is usually a circular equipment, which engages a linear bar that has been fitted with teeth, known as the rack; power is applied to the pinion leading to it to rotate, which subsequently makes the rack move around in regards to the pinion, which converts the rotational motion of the pinion into linear movement. For electric home window openers, the rack is housed in external casing and is attached to the screen. As the pinion techniques, the rack can be 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 up inwards, outwards or both ways.

The 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 For Window Opener equipment rack, the slide rack when the pushing deal with on the door, so that the rotation from the apparatus rack fixed on the door, the door movement, so that the door is opened, with a equipment 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.
