Cordless roller blind structure improvement

The present invention relates to a cordless roller blind structure improvement, and more particularly to a cordless roller blind that is kept flat when the roller shutter unit is lowered.

According to modern buildings, ventilation and lighting are used. Almost every room has windows, and even large-scale floor-to-ceiling windows are designed for users to look out for outdoors. However, the design of the windows is also easy to be exposed to direct sunlight. The temperature rises, or the indoor situation is lacking, such as peeping by outsiders. Therefore, curtains are often added to the windows to take into account the privacy of the room and to shield the sun, adjust the light and decorate the wall. The traditional curtains are all pulled. The rope is used for controlling movement, such as a roman blind, a folding neck curtain or a hundred-fold curtain. The rope is usually dropped from the upper beam to where the hands can be pulled. When the rope is pulled, the curtain can be controlled. When the horizontally moved, the pull cord type curtain will be installed on one side of the curtain, which affects the appearance and the user must personally go to the drawstring of the curtain to operate, but cannot be remotely controlled. Lifting movement, convenience is obviously insufficient, and when there are children in the family, when the child accidentally wraps the exposed drawstring around the neck due to curiosity or play, it is very likely that it is difficult to break free. Le neck of wrongful death, worthy of consideration for the safety of young children. Therefore, in order to avoid the use of the exposed drawstring, an electric curtain (shown in FIG. 8) appears on the market, which mainly includes a scrolling unit 5 and a curtain 6, and the scrolling unit 5 is provided. There is a shaft 51, the top end of the curtain 6 is consolidated with the axis 51 of the scroll unit 5, and the curtain 6 can be wrapped around the shaft 51 by the rotation of the shaft 51 or The lower roll is released, so it is safe and convenient to use.

However, as far as the above is known, the curtain 6 is automatically rotated by the rotation of the shaft 51 of the scroll unit 5, but the curtain 6 is not wound on both sides. The supporting force is easy to cause bending on both sides, which causes the unevenness of the curtain 6 to be unfolded, resulting in the overall appearance of the electric curtain being used, and there is still no improvement in practical application. It is a big drawback, and it needs to be improved.
