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： The structures described herein use an actuating system that can selectively switch between a lower and a raise mode of operation by rotating a rod assembly, and use a downward displacement of a pull member to lower and raise the window shade depending on whether its switching state. The actuating systems are simple to operate, allow convenient adjustment of the window shade, and are safe as the pull member has a limited length of extension.

摘要： A control module of a window shade includes a drive axle affixed with a sleeve, an arrester assembled around the sleeve, a cord drum connected with an operating cord, a clutch operable to couple and decouple the cord drum with respect to the drive axle, and a release unit including a stick that is operatively connected with the arrester. The arrester blocks rotation of the drive axle in a locking state, and has an unlocking state allowing rotation of the drive axle. The operating cord is pulled to drive the cord drum in rotation and turn the clutch to a coupling state, such that the rotation of the cord drum is transmitted through the clutch to drive the drive axle in rotation for raising the shading structure. Moreover, the stick is operable to switch the arrester from to the unlocking state for lowering the shading structure by gravity action.
