They need to be cleaned and wiped frequently, and their service life is short. In order to solve this problem, someone has proposed a kind of technical scheme that door / curtain is arranged between double glass, as the patent of invention that the patent No. is 00204290.8. However, this techni...

Problems solved by technology

However, this technical solution adopts the method of folding and shrinking the curtain. In practice, it is difficult to fold the curtain in the desired way. Even if it is folded, a folding area of ​​a certain height will be formed between the double-layer glass, which will affect the vision. effect; especially the friction between the curtain and the glass on both sides after the curtain is folded will prevent the joystick from moving to the target height; in addition, unless the window is very low, such as like a train window, the operator needs to stand very high to use the hand Raise the joystick to the desired height

[0003] In addition, unless there is a stretching device at the free end, the general roller blinds move up and down, which is only suitable for vertically installed doors / windows, and cannot be used in roof skylights, arc-shaped windows and other irregular windows.
