Patent attributes
An actuating system for a window shade includes an axle coupling part rotatable for raising or lowering a bottom part of a window shade, an arresting part and an arrester coupling part connected with each other, the arresting part having a braking state and a release state, a clutching part carried with the arrester coupling part and movable relative to the arrester coupling part between a retracted state where the clutching part is disengaged from the axle coupling part and an extended state where the clutching part is engaged with the axle coupling part, and an actuating wheel movably linked to the clutching part, the actuating wheel being rotatable in a first direction to urge the clutching part to move from the retracted state to the extended state, and in an opposite second direction to urge the clutching part to move from the extended state to the retracted state.
