It is simple in structure, easy to install, just gently drive the rack in the sliding door manage on the door frame, the door can be easily opened.
The opening mechanism for a rack and pinion functions by converting rotational movement into linear motion. The pinion is definitely a circular equipment, which engages a linear bar that has been fitted with teeth, referred to as the rack; power is usually put on the pinion causing it to rotate, which subsequently makes the rack move in relation to the pinion, which converts the rotational motion of the pinion into linear motion. For electric windows openers, the rack is usually housed in exterior casing and is attached to the home window. As the pinion movements, the rack can be pushed out, starting the windows along with it.
These are usually fitted to side hung home windows or doors, because they Gear Rack For Window Opener provide a 90-degree opening. They are also known as folding arm actuators and may be designed to open up inwards, outwards or both ways.

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 manage on the entranceway, so that the rotation from the gear rack fixed on the door, Open the window racks 1the entranceway movement, so that the entranceway 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 dual rack door when the sliding door.
