Title: Roller curtain fixing bracket assembly

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates generally to a roller curtain fixing bracket assembly for installing a roller curtain device thereon, and more particularly to a roller curtain fixing bracket assembly, which is able to stabilize the raising/lowering operation of the roller curtain and beautify the appearance of the roller curtain as well as protect the roller curtain. 
     2. Description of the Related Art 
     Currently, a roller curtain is installed in such a manner that two supports are mounted on two sides of a window and the roller curtain device is directly installed on the supports. A protection board is further mounted on the supports for covering the roller curtain. In raising/lowering operation of the roller curtain, a pull force is applied to the supports. It often takes place that the supports cannot bear the pull force and detach from the wall face and drop down. Therefore, the above fixing structure can hardly securely fix the roller curtain on the wall face. Moreover, the protection board is simply hung on the supports so that the protection board can be hardly securely mounted on the supports. 
     SUMMARY OF THE INVENTION 
     It is therefore a primary object of the present invention to provide a roller curtain fixing bracket assembly, which enables a user to quickly install a roller curtain device and is able to beautify the appearance of the roller curtain. The roller curtain fixing bracket assembly includes a left support, a right support, a decoration board and two cover boards covering the left and right supports. A roller curtain device can be installed between the main bodies of the left and right supports. Each of the left and right supports has a plane board main body and several fixing boards perpendicularly protruding from outer edges of the plane board main body. Front edge of each of two fixing boards extending from two sides of the plane board main body is formed with a split. The decoration board has a horizontal panel and a vertical panel. A top end and a certain section of the vertical panel are formed with hook bars, which are directly inserted and latched in the splits of the left and right supports and assembled therewith. In addition, by means of the holes of the fixing boards of the left and right supports, the left and right supports are respectively fixedly mounted on the wall faces of two sides of a window. The roller curtain device is installed between inner faces of the left and right supports and positioned above the window and concealed by the decoration board so as to achieve a beautiful appearance. In addition, the main bodies of the left and right supports are formed with two sets of fixing holes in horizontal direction and vertical direction. According to the requirements of different windows, the roller curtain device can be fixed in a horizontal state or a vertical state. Therefore, the position of the roller curtain can be changed to provide different sunshine shading effects.
