Pleated blind having positioning function

Abstract

A pleated blind includes a blind body having a plurality of pleated portions each having a pleated edge, and a limit cord secured to the pleated edges of the pleated portions of the blind body. When the pleated portions are moved, the maximum distance between any two adjacent pleated edges of the pleated portions is limited by the limit cord, so that the open distance of each of the pleated portions is limited by the limit cord to reach a determined value. Thus, each of the pleated portions will not be opened excessively due to improper operation by a user, thereby preventing either one of the pleated portions from being deformed or distorted due to an overload so as to enhance the outer appearance of the pleated blind.
