摘要： A window shade includes a reel and a roller pivotally connected with a head frame at two spaced-apart positions, a clutch operatively connected with the roller and switchable between an engaged state preventing the roller from rotating in a first direction and a disengaged state for rotation of the roller in an opposite second direction, and a panel assembly including multiple transversal vanes respectively connected with a first and a second panel. The reel is rotatable to wind and unwind the panel assembly with the first panel remaining in contact with the roller. The panel assembly is switchable between an open state for light passage and a closed state blocking light passage by rotating the transversal vanes. The reel is rotatable in an unwinding direction while the roller is kept stationary by the clutch in the engaged state for switching the panel assembly from the closed to open state.

摘要： An actuating system for a window shade includes a fixed support shaft, a rotary drum pivotally connected with the support shaft and rotatable for winding or unwinding a shading structure, and a limiting mechanism at least partially disposed inside the rotary drum and including a threaded portion provided on the support shaft, a stop portion and a limiting part respectively adjacent to a first and a second end of the threaded portion, and a follower engaged with the threaded portion, the follower being rotationally coupled to the rotary drum and slidable relative to the rotary drum. The rotary drum is rotatable in a first direction to drive the follower to slide toward a first position for engagement with the limiting part, and in a second direction to drive the follower to slide toward a second position for engagement with the stop portion.

摘要： A window shade includes a reel and an aperture control module respectively assembled with a head frame, and a panel assembly including transversal vanes respectively connected with two panels. The reel is rotatable to wind and unwind the panel assembly. The aperture control module includes a positioning arm connected with a rubbing roller, and is operable to rotate the rubbing roller relative to the positioning arm and to displace the positioning arm and the rubbing roller between two positions, the rubbing roller being displaced away from a sidewall of the head frame in a first position and pressing the panel assembly against the sidewall in a second position, the rubbing roller being further rotatable relative to the positioning arm in the second position to cause relative sliding between the two panels for switching the panel assembly from a closed state blocking light passage to an open state allowing light passage.
