Abstract
A Venetian blind comprises a top rail, a tilting device, two or more ladders, a bottom rail, a predetermined number of drawing cords, a drawing cord pulley retainer, and a predetermined number of slats. Each of the slats is provided with a through hole corresponding in location to a drawing cord, and with a ladder hole corresponding in location to each of ladders, and further with a slit extending in a predetermined direction from the ladder hole. The ladder has two suspension cords, one of which is received in the ladder hole through the slit. Each of the slats is provided with an extension section with an outer side edge and an inner side edge. The outer side edge of the extension section of one slat is capable of forming a lap joint with the inner side edge of the extension section of another slat at the time when the slats are set to keep out the light. The lap joint serves to obstruct the through holes and to conceal the ladders and the drawing cords.
