<P>PROBLEM TO BE SOLVED: To provide optimum lighting by using a ladder cord having an unequal pitch part and an equal pitch part in a horizontal blind. <P>SOLUTION: First vertical cords 14a and 16a and second vertical cords 14b and 16b are suspended respectively at an interval from a head box attached to a wall surface or a ceiling in the extending direction of the line of intersection of a surface orthogonal to the longitudinal direction of the head box and a horizontal surface, and a plurality of horizontal cords 14c and 16c for supporting a plurality of slats respectively are disposed to the first vertical cords 14a and 16a and the second vertical cords 14b and 16b. The unequal pitch part 14 is formed such that a connection pitch of one end of each horizontal cord 14c to the first vertical cord 14a and a connection pitch of the other end of each horizontal cord 14c to the second vertical cord 14b are different, and the equal pitch part 16 is formed such that the connection pitch of each of the plurality of horizontal cords 16c to the first vertical cord 16a and the connection pitch of the other end of each horizontal cord 16c to the second vertical cord 16b are the same. <P>COPYRIGHT: (C)2012,JPO&INPIT |
