It really is simple 
in structure, easy to install, simply gently force the rack in the sliding door manage on the door 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 can be a circular gear, which Gear Rack For Window Opener engages a linear bar that has been 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 in regards to the pinion, which converts the rotational motion of the pinion into linear movement. For electric window openers, the rack is definitely housed in exterior casing and is attached to the windowpane. As the pinion moves, the rack can be pushed out, starting the window along with it.
These are usually suited to side hung home windows or doors, as they provide 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 guts gear 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 might be engaged with the stationary gear rack, the slide rack when the pushing deal with on the entranceway, so that the rotation from the apparatus rack fixed on the entranceway, the entranceway 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 gadget with a special dual rack door when the sliding door.
