Abstract
Lower end portions of the life cords of a Venetian blink assembly are retained within the bottom rail of the assembly by a helical tension spring that is normally in an unexpanded or unloaded condition when the bottom rail is moved toward or away from the top rail by manipulating the lift cords. When the bottom rail is held in fixed position relative to the top rail, the lower end portions of the lift cords can be pulled from within the bottom rail to expand the spring so as to apply a user controllable tensioning force on the lift cords which are then locked in position. The now tensioned lift cords serve to maintain and stabilize the position of the ladder and slat structure of the blind assembly where it is mounted in a moving vehicle, for example, or where it is inclined from a vertical plane. The bottom rail also includes a concealed clip and end caps for interconnecting generally identical upper and lower portions of the bottom rail, and a connector for facilitating the connection of the lower ends of the ladder to the bottom rail.
