54 Abstract Disclosed are a
window covering and a
window covering operation mechanism. The
window covering operation mechanism includes a driving connector fixed to a roller, a base, a torsional direction switching mechanism, a driving member, a driven member, a reversal cord, and a lift cord. When the reversal cord is dragged, the driving member is 5 driven to rotate, whereby plural bumps of the driving member are guided by plural guiding rails of the base, making the driving member drive the driven member to move together while rotating. When the lift cord is dragged, the driven member is driven to rotate with respect to the driving member, driving the driving connector directly or through the torsional direction switching mechanism according to the position of the 10 driven member for outputting a torsional force in the forward or reverse direction to the roller, thereby controlling retraction or extension of the window covering.
