Abstract
A hypocycloid drive device for adjusting slat angles of a venetian blind includes a housing, a roller, a hypocycloid drive reducer, a tilt cord and a tilt rod. The roller is rotatably mounted in the housing and is rotated by pulling the tilt cord. The hypocycloid drive reducer is coupled to the roller and is used to reduce an angular speed of and rotate the tilt rod. The tilt rod is adapted to change slat angles of the venetian blind. Consequently, volume of the hypocycloid drive device is minimized to accommodate convenient installation of the hypocycloid drive device.
