Abstract
The adjustment cords of a window blind extend downwardly over a first pin fixedly located within a headrail. A second pin in the headrail adjacent the fixed pin has its ends slidably received in a slot enabling movement in a plane closely adjacent to the first pin. The second pin is in continuous contact with the cords and the relative dimensions of the pins and the cofining constraints of the headrail are such that for the standard diameter of the cord, locking engagement will be obtained when the two pins are located in the same horizontal plane. The guide slot for the second pin allows the pin to move to a point past the horizontal plane of normal locking engagement and closer to the fixed pin enabling locking engagement even if the cord diameter is less than normal. The second pin is constructed of a leaded steel subjected to sandblasting which produces a rough and pitted surface on the pin enhancing frictional engagement with the cord.
