The cords 16, 16 min for controlling a pleated fabric blind hanging from a head-rail 12 pass over a fixed pin 29 and hang down at the edge of the blind. In this condition they engage a pin 32 which is slidable in end slots 34. The weight of the blind pulls the cord upwards and the pin 32 is dragged up to grip the cord between the pins 29 and 32, thereby locking the cord. For adjustment of the blind the cords are pulled to one side against the inclined surface 21, allowing the pin 32 to fall and thereby freeing the cord lock. |
