A window covering device has a top rail, a middle rail, and a bottom rail. A covering is connected with the middle rail and the bottom rail. Two cord controllers and two cord sets are provided in the top rail. The two cord sets are mounted respectively through the cord controllers. One cord set is connected with the middle rail, and the other cord set is connected with the bottom rail through the middle rail and the covering, thus the window covering is able to be opened from lower part or from upper part. The top rail, middle rail and the bottom rail are all made of plastic. The window covering device can be adjusted conveniently as people's desire.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a window covering device, and particularly relates to a window covering device that is capable of spreading and folding, and is mounted at window or French window, to adjust the indoor brightness.[0003]2. Description of the Related Art[0004]Window covering device is necessary as a part of a room nowadays. A conventional window covering device is normally opened and closed vertically or horizontally covering.[0005]The window covering device opened and closed vertically above normally includes a top rail with a cord and a cord controller, a covering is connected to a bottom of the top rail, and a bottom rail is mounted at a bottom of the covering. The top rail is mounted at a top edge of a window frame, and the cord is able to control the bottom rail by the cord controller. The bottom rail brings the covering to spread or to be folded. However, the covering is fixed on the top rail, so the...
