Designed to open and close home windows in difficult to reach areas, electric windows openers, or actuators, are exceptionally handy.
They work with a motorised folding arm that’s attached to a windows. The arm begins in a folded placement, however since it is run by the electric motor, it starts to unfold. The arm is positioned in a manner that as it starts to unfold, the home window begins to open up. To close a home window, the arm starts to fold back up into its initial position, bringing the windowpane to a close.
It is simple in structure, easy to install, just gently push the rack in the sliding door manage on the door frame, the door can be easily opened.
The opening mechanism for a rack and pinion functions by converting rotational movement into linear motion. The pinion is usually a circular gear, which engages a linear bar that is fitted with teeth, known as the rack; power is certainly applied to the pinion leading to it to rotate, which Automatic Window Opening System gear rack subsequently makes the rack move in relation to the pinion, which converts the rotational movement of the pinion into linear movement. For electric windowpane openers, the rack is usually housed in external casing and is attached to the window. As the pinion moves, the rack is certainly pushed out, opening the window along with it.
These are usually fitted to side hung windows or doors, because they offer a 90-degree opening. They are also called folding arm actuators and will be designed to open 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 may be engaged with the stationary gear rack, the slide rack when the pushing manage on the entranceway, so that the rotation from the gear 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.
