ABSTRACT:
A roller assembly for a Venetian blind includes a rotating rod which has a rectangular axial hole formed therethrough. A portion of a pull cord is wound on the rotating rod so as to move slats vertically. A movable member of a rectangular cross-section is engaged in the rotating rod and has a threaded axial hole formed therethrough. An elongated driving member has a shaft section of a rectangular cross-section engaged within the rectangular axial hole of the rotating rod, a driven wheel section secured to the shaft section, and a circular axial hole formed through the shaft section and the driven wheel section. A lift cord is disposed on the driven wheel section. A guide unit is mounted securely on a window frame and includes a threaded horizontal rod extending through the circular axial hole of the driving member and through the threaded hole of the movable member. Accordingly, when the lift cord is pulled, the driving member rotates the rotating rod so as to move the movable member on the threaded horizontal rod of the guide unit, thereby rotating and moving the rotating rod on the guide unit.
