It really is simple in framework, easy to install, just gently push 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 functions by converting rotational motion into linear motion. The pinion is certainly a circular equipment, which engages a linear bar that has been fitted with teeth, known as the rack; power is definitely put on the pinion causing it to rotate, which subsequently makes the rack move in relation to the pinion, which converts the rotational movement of the pinion into linear motion.

The object of the present invention is achieved, through the center 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 gear 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 motion, so that the entranceway is Gear Rack For Window Opener opened, with a gear fixed to the frame reset spring.

The object of today’s invention is to supply a gadget with a special double rack door when the sliding door.
