Designed to open up and close home windows in difficult to attain areas, electric screen 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 windowpane begins to open up. To close a screen, the arm starts to fold back up into its first Automatic Window Opening System gear rack position, bringing the windows to a close.
It really is simple in structure, 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 works by converting rotational motion into linear motion. The pinion is a circular equipment, which engages a linear bar that has been fitted with teeth, known as the rack; power is applied to the pinion causing it to rotate, which subsequently makes the rack move in regards to the pinion, which converts the rotational movement of the pinion into linear motion. For electric window openers, the rack is definitely housed in external casing and is attached to the windows. As the pinion techniques, the rack is 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 may be designed to open up inwards, outwards or both ways.
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 could be engaged with the stationary gear rack, the slide rack when the 
pushing handle on the entranceway, to ensure that the rotation from the gear rack fixed on the entranceway, the entranceway motion, so that the door is opened, with a equipment fixed to the frame reset spring.
The object of today’s invention is to supply a device with a special dual rack door when the sliding door.
