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

They work via a motorised folding arm that’s attached to a home window. The arm starts in a folded placement, however as it is run by the motor, it starts to unfold. The arm is put in a manner that as it starts to unfold, the home window begins to open up. To close a screen, the arm begins to fold back again up into its first position, bringing the windowpane to a close.

It is simple in framework, easy to install, just gently push 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 functions by converting rotational movement into linear motion. The pinion can be a circular equipment, which engages a linear bar that is fitted with teeth, known as the rack; power is put on the pinion causing 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 screen openers, the rack is usually housed in exterior casing and is attached to the windows. As the pinion techniques, the rack is certainly pushed out, opening the screen along with it.
These are usually suited to side hung windows or doors, because they provide a 90-degree opening. They are also known as 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 guts 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 might be Automatic Window Opening System gear rack engaged with the stationary gear rack, the slide rack when the pushing deal with on the entranceway, to ensure that the rotation from the gear rack fixed on the entranceway, the entranceway movement, so that the entranceway is opened, with a equipment fixed to the frame reset spring.

The object of today’s invention is to provide a device with a special double rack door when the sliding door.
