When fixing the roller blind on an inner window frame or an outerwindow frame, it is necessary to first fix a fixing seat on a suitable portion of the inner window frame or outer window frame for fixing the roller blind frame rail.A conventional roller blind frame rail has two ends each formed with an opening. Therefore, when changing the installation position of the conventional roller blind, many different fixing seats are needed for fixing the roller blind. This leads to wasteand makes it inconvenient to install the roller blind.
It is a further object of the present invention to provide the above side cover of the roller blind frame rail, in which two breaking flutes are respectively formed on two sides of an inner face of the closing board. The closing board can bebroken apart along a breaking flute to form a plane edge for snugly attaching to the window frame.
It is still a further object of the present invention to provide the above side cover of the roller blind frame rail, in which the three insertion plates are a transverse insertion plate and two vertical insertion plates. Two arced guide wallsare formed on the inner face of the closing board. The arced guide walls curvedly outward extend from inner sides of the vertical insertion plates respectively for enlarging operation angle of a bead chain and facilitating operation thereof.
It is therefore a primary object of the present invention to provide a side cover of a roller blind frame rail for closing an opening of a tail end of the roller blind frame rail. The side cover also serves to fix the roller blind frame rail ona window frame.
It is still a further object of the present invention to provide the above side cover of the roller blind frame rail, in which the three insertion plates restrict the bead chain within a space so as to avoid detachment thereof.
The above embodiments are only used to illustrate the present invention, not intended to limit the scope thereof. Many modifications of the above embodiments can be made without departing from the spirit of the present invention.
It is still a further object of the present invention to provide the above side cover of the roller blind frame rail, in which three insertion plates perpendicularly project from the closing board for tightly connecting the closing board with theframe rail to close the opening thereof.
