ABSTRACT:
A door/window frame structure including two lateral columns. Several slats are disposed between the two lateral columns. Each lateral column is a U-shaped body. One side of the surface of the lateral column is formed with a row of through holes corresponding to the slats. Two inner side walls of the lateral column are respectively formed with a rib. One of the side walls is disposed with two parallel stopper walls between which a rack is mounted. An inner side of each through hole is disposed with a T-gear meshing with the rack. The T-gear is formed with a central rectangular hole. One side of each slat is disposed with a shaft rod having a rear rectangular post passed through each through hole of the lateral column to insert into the rectangular hole of the T-gear. A cover board is mated with the lateral column. One side of the cover board is disposed with two parallel latch ribs and an outer side of each latch rib is formed with a latch channel. When covering the open side of the U-shaped lateral column, the ribs of the lateral column are just engaged and latched in the latch channels. A lower section of the other side wall of the lateral column is formed with a rectangular perforation. A rotary wheel engaged with the rack partially protrudes out of the perforation. The rotary wheel is formed with a central rectangular hole in which a shaft pin is inserted. The rotary wheel can be rotated on outer side to drive the rack which further drives each T-gear to rotate so as to drive each slat. The door/window frame can be assembled without using any tool and the angle of the slats can be synchronously adjusted.
