摘要

PURPOSE: A structure for opening/closing windows and doors using a gear technique is provided to prevent windows and doors from becoming twisted due to structural stability, to extend the lifespan and to reduce noise and vibration. CONSTITUTION: A structure for opening/closing windows and doors using a gear technique is as follows. A sector fixing piece(12) is horizontally formed on the vertical frame(111) of the upper frame of a window frame. A semicircular fixed groove bar(121) is formed on the upper part of the sector fixing piece in a length direction. A sector fixing gear(122) is formed on the outer circumferential surface of the groove bar in a length direction. A sector moving piece(22) is upwardly formed on the upper part of the upper frame of the window frame. A semicircular moving groove bar(221) is formed in the sector moving piece in a length direction. A sector moving gear(222) is formed on the outer circumferential surface of the moving groove bar in a length direction.
