It really is simple in structure, easy to install, simply gently press the rack in the sliding door deal with on the entranceway frame, the door can 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 equipment, which Automatic Window Opening System gear rack engages a linear bar that is fitted with teeth, referred to as the rack; power can be put on the pinion causing it to rotate, which subsequently makes the rack move around in regards to the pinion, which converts the rotational motion of the pinion into linear motion.

These are usually suited to side hung home windows or doors, because they provide a 90-degree opening. Also, they are called folding arm actuators and will be designed to open inwards, outwards or both ways.

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 apparatus rack fixed on the entranceway, the door motion, so that the door is opened, with a gear fixed to the frame reset spring.

The object of the present invention is to provide a device with a special double rack door when the sliding door.
