HINGED COMPLEX WINDOW FRAME STRUCTURE

摘要

The present invention relates to a hinged complex window frame structure which comprises: a vertical bar-shaped main frame (100) fastened to be hinged to a door frame (10) and installed to be able to rotate back and forth; an inner window frame (201) fastened to be hinged to the front end part of the main frame (100) and mounted to be able to rotate; an outer window frame (202) fastened to be hinged to the rear end part of the main frame (100) and mounted to be able to rotate; and a blind (203) mounted at the center of the main frame (100) and positioned between the inner window frame (201) and the outer window frame (202), wherein the inner window frame (201) includes an inner-outer frame (211) forming the exterior thereof and an inner window (221) inserted into the inner-outer frame (211), and the outer window frame (202) includes an outer-outer frame (212) forming the exterior thereof and an outer window (222) inserted into the outer-outer frame (212). According to the present invention, the window frame, and the inner window frame, the outer window frame, and the windows which form the window frame are capable of being opened and closed by rotations so that use convenience can be improved; the blind detachably and internally installed between the inner window frame and the outer window frame blocks a light from the outside and prevents exposure to the outside so that marketability can be improved; and the windows capable of being opened or closed allow the maintenance and replacement of the blind to be easily performed and allow the replacement thereof to be easily performed so that work convenience for a user can be improved.
