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

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

It is simple in framework, easy to install, simply gently force the rack in the sliding door deal with on the entranceway frame, the door could be easily opened.
The opening mechanism for a rack and pinion functions by converting rotational motion into linear movement. The pinion is a circular gear, which engages a linear bar that has been fitted with teeth, referred to as the rack; power can be put on the pinion leading to it to rotate, which subsequently makes the rack move in relation to the pinion, which converts the rotational motion of the pinion into linear movement. For electric home window openers, the rack can be housed in external casing and is mounted on the home window. As the pinion movements, the rack is pushed out, starting the screen along with it.
These are usually suited to side hung windows or doors, because they offer a 90-degree opening. They are also known as folding arm actuators and may be designed to open up inwards, outwards or both methods.

The object of today’s invention is achieved, through the Gear Rack For Window Opener center 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 equipment rack, the slide rack when the pushing handle on the door, so that the rotation from the gear rack fixed on the entranceway, the entranceway movement, so that the door is opened, with a equipment fixed to the frame reset spring.

The object of the present invention is to supply a device with a special double rack door when the sliding door.
