Designed to open and close home windows in difficult to reach areas, electric windows openers, or actuators, are Automatic Window Opening System gear rack exceptionally handy.
They work via a motorised folding arm that’s attached to a window. The arm starts in a folded position, however as it is run by the engine, it starts to unfold. The arm is put in a manner that as it starts to unfold, the home window begins to open. To close a home window, the arm starts to fold back again up into its initial position, bringing the window to a close.
It is simple in framework, easy to install, simply gently force 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 motion into linear motion. The pinion is definitely a circular gear, which engages a linear bar that has been fitted with teeth, known as the rack; power is certainly 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 windows openers, the rack is certainly housed in external casing and is mounted on the window. As the pinion techniques, the rack is usually pushed out, starting the windows along with it.
These are usually suited to side hung windows or doors, because they provide a 90-degree opening. Also, they 
are known as folding arm actuators and can be designed to open 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 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 door 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.
