Designed to open up and close 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 position, however as it is run by the electric motor, it starts to unfold. The arm is positioned in a way that as it starts to unfold, the windows begins to open. To close a home window, the arm begins to fold back up into its initial position, bringing the windows to a close.

It is simple in framework, easy to install, just gently press the rack in the sliding door manage on the Automatic Window Opening System gear rack entranceway frame, the door could be easily opened.
The opening mechanism for a rack and pinion functions by converting rotational movement into linear movement. The pinion is certainly a circular equipment, which engages a linear bar that has been fitted with teeth, known as the rack; power can be 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 window openers, the rack can be housed in exterior casing and is attached to the windows. As the pinion moves, the rack can be pushed out, starting the home 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 may be designed to open up inwards, outwards or both methods.

The object of the present invention is achieved, through the center 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 gear rack, the slide rack when the pushing deal with on the door, to ensure that the rotation from the gear 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 today’s invention is to supply a device with a special double rack door when the sliding door.
