    • A cordless blind includes a headrail, a bottom rail suspended from the headrail by a first cord and a second cord, a wall covering disposed between the headrail and the bottom rail, and a drive actuator. The drive actuator includes a spring motor, a spool coupled to the spring motor, a first tensioning mechanism, and a second tensioning mechanism. The first and second tensioning mechanisms are configured to impact a resistant force on movement of the first and second cords. The drive actuator may include a spool, a spring motor, a biasing element configured to provide a force biased against movement of the bottom rail, and a bias relief mechanism that is configured to provide for selective application and relief of the biasing force by the biasing element. The drive actuator may include a constant biasing element, a generally rigid strap, a mandrel, a biasing member, and a traction wheel including a plurality of cogs extending from the circumference of the traction wheel such that movement of the strap rotates the traction wheel.
    • 无绳盲板包括头轨,通过第一帘线和第二帘线从头轨悬挂的底轨,设置在头轨和底轨之间的壁覆盖件以及驱动致动器。 驱动致动器包括弹簧马达,联接到弹簧马达的线轴,第一张紧机构和第二张紧机构。 第一和第二张紧机构构造成在第一和第二帘线的运动上冲击抵抗力。 驱动致动器可以包括线轴,弹簧马达,被配置为提供抵抗底部轨道运动的力的偏置元件,以及偏置释放机构,其被配置为提供偏置力的选择性施加和偏置力 元件。 驱动致动器可以包括恒定的偏置元件,大致刚性的带,心轴,偏置构件和牵引轮,该牵引轮包括从牵引轮的圆周延伸的多个齿,使得带的运动旋转牵引轮。
