It is simple in structure, easy to install, just gently drive the rack in the sliding door handle 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 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 leading to 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 movement.

These are usually suited to side hung windows or doors, as they provide a 90-degree opening. They are also called folding arm actuators and can be designed to open up inwards, outwards or both ways.

The object of the Automatic Window Opening System gear rack present 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 might 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 door, the entranceway motion, 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 device with a special double rack door when the sliding door.
