PURPOSE: A children safety device of a blind having an adjustment string is provided to always accommodate the adjustment string inside a weight, thereby basically preventing a loop from being formed at the lower end of the adjustment string. CONSTITUTION: One end of a spring(11) is fixed to a bracket(12). The bracket(12) is moved along the horizontal direction of a weight(10) by a guide means. Two idle rollers(16a,16b) guides the movement of an adjustment string(5). The adjustment string(5) is wound on a winding device(6). One end of the adjustment string(5) passes through the vertical hole(17) of the weight(10). The other end of the adjustment string(5) is wound on a guide roller(13) through the idle roller(16b), and passes through the idle roller(16a). |
