It is simple in framework, easy to install, simply gently press the rack in the sliding door manage on the entranceway frame, the door could be easily opened.
The opening mechanism for a rack and pinion works by converting rotational movement into linear motion. The pinion is usually a circular gear, which engages a linear bar that has been fitted with teeth, known as the rack; power can be applied to the pinion causing it to rotate, which subsequently makes the rack move in regards to the pinion, which converts the rotational motion of the pinion into linear motion. For electric windows openers, the rack can be housed in external casing and is attached to the windows. As the pinion moves, the rack can be pushed out, starting the screen along with it.
These are usually suited to side hung windows or doors, because they provide 
a 90-degree opening. Also, they are called 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 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 today’s invention is to supply a gadget with a special dual rack door when the sliding door.
