Designed to open and close home windows in difficult to reach areas, electric window openers, or actuators, are exceptionally handy.
They work via a motorised folding arm that is attached to a window. The arm begins in a folded position, however since it is driven by the electric motor, it begins to unfold. The arm is put in a manner that as it starts to unfold, the window begins to open. To close a screen, the arm begins to fold back again up into its unique 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 can be easily opened.
The opening mechanism for a rack and pinion functions by converting rotational motion into linear movement. The pinion is certainly a circular equipment, which engages a linear bar that is fitted with teeth, known as the rack; power is 
usually put on the pinion leading to it to rotate, which subsequently makes the rack move around in relation 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 screen. As the pinion movements, the rack is usually pushed out, opening the windowpane along with it.
These are usually fitted to side hung home windows or doors, as they offer a 90-degree opening. They are also known as folding arm actuators and can be designed to open inwards, outwards or both ways.
The object of today’s invention is achieved, Gear Rack For Window Opener through the guts 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 may be engaged with the stationary equipment rack, the slide rack when the pushing handle on the entranceway, so that the rotation from the gear rack fixed on the entranceway, the door movement, so that the door is opened, with a gear fixed to the frame reset spring.
The object of the present invention is to provide a gadget with a special double rack door when the sliding door.
