    • A retractable covering for an architectural opening is reversibly driven through an input assembly, a transmission and an output assembly by a reciprocal operating cord that can be pulled down by an operator and will automatically retract while the covering is held in a predetermined position. While the input assembly is always driven in a first direction, a transmission is shifted between two operative positions through movement of a shift arm depending upon the positioning of the shift arm by the operating cord. The shift arm is pivotal about an axis parallel with a roller for the covering and when the operating cord is pulled straight downwardly, the covering is moved in an upwardly or retracting direction while if the operating cord is pulled downwardly and toward the operator, i.e. away from the architectural opening, the covering is driven in a downwardly or extending direction.
    • 用于建筑开口的可收回的覆盖物通过可由操作者向下拉动的往复操作绳通过输入组件,变速器和输出组件可逆地驱动,并且在覆盖物保持在预定位置时将自动缩回。 当输入组件总是沿第一方向被驱动时,根据换档臂由操作绳的定位,通过换档臂的移动,变速器在两个操作位置之间移动。 换档臂围绕平行于用于覆盖物的辊的轴线枢转,并且当操作绳索被直线向下拉动时,盖子沿向上或向后的方向移动,同时如果操作绳被向下拉并且朝向操作者,即远离 从建筑开口,覆盖物向下或延伸方向被驱动。
