It is simple in structure, easy to install, simply gently force 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 movement into linear motion. The pinion is certainly a circular equipment, which engages a linear bar that is fitted with teeth, referred to as the rack; power is put on the pinion causing it to rotate, which subsequently makes the rack move around in relation to the pinion, which converts the rotational motion of the pinion into linear motion.

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 gear rack, the slide rack when the pushing deal with on the entranceway, to ensure that the rotation from the apparatus rack fixed on the entranceway, the entranceway movement, so that the door is opened, with a gear fixed to the frame reset spring.
The object of today’s invention is to provide a gadget with a special double rack door when the sliding door.
