TILT ANGLE ADJUSTING DEVICE FOR SLATS OF A VENETIAN BLIND
A venetian blind includes a top frame receiving a coiling and uncoiling mechanism for folding and unfolding slats. An adjusting mechanism is mounted to the top frame for adjusting a tilt angle of each slat and includes two pivotal casing. Each of two ends of each pivotal casing includes two opposite outer sides to which two ladder strings are disposed, respectively. Each ladder string has a lower end extending through and secured to each slat. Two side strings are wound around the coiling and uncoiling mechanism. Each side string has a lower end extending through each slat and fixed to the bottommost slat. Each side string is hooked by an actuating member to extend through a spacing between two pegs parallel to an axial direction of each tube. Each actuating member interlocks with an associated pivotal casing to move in unison in a circumferential direction.
