It is simple in structure, easy to install, simply gently drive the rack in the sliding 
door deal with on the door frame, the door could be easily opened.
The opening mechanism for a rack and pinion functions by converting rotational Gear Rack For Window Opener motion into linear motion. The pinion is usually a circular equipment, which engages a linear bar that is 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 regards to the pinion, which converts the rotational motion of the pinion into linear movement. For electric windows openers, the rack can be housed in exterior casing and is mounted on the home window. As the pinion moves, the rack can be pushed out, opening the screen along with it.
These are usually suited to side hung home windows or doors, as they provide a 90-degree opening. Also, they are known as folding arm actuators and can be designed to open up inwards, outwards or both methods.
The object of the present 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 might be engaged with the stationary equipment rack, the slide rack when the pushing manage on the door, so that the rotation from the apparatus rack fixed on the door, the door motion, so that the door is opened, with a equipment fixed to the frame reset spring.
The object of today’s invention is to provide a gadget with a special dual rack door when the sliding door.
