| 发明名称 | Window shade and actuating system thereof | ||
| 摘要 | An actuating system for a window shade includes a suspension member, a casing having a fixed protrusion, a transmission axle disposed through the casing, a rotary drum arranged in the casing and rotationally coupled with the transmission axle, and an impeding part connected with the rotary drum and affixed with an end of the suspension member. The rotary drum is rotatable in a first direction for winding the suspension member, and in a second direction for unwinding the suspension member. The impeding part is movable relative to the rotary drum between a first and a second position, the impeding part when in the first position being movable with the rotary drum past the protrusion in any of the first and second direction, and the impeding part when in the second position being engageable with the protrusion to block rotation of the rotary drum in the second direction. | ||

| 主权项 | 1. An actuating system for a window shade, comprising: a suspension member; a casing having a fixed protrusion; a transmission axle disposed through the casing; a rotary drum arranged in the casing and rotationally coupled with the transmission axle, the rotary drum being rotatable in a first direction for winding the suspension member around the rotary drum, and in a second direction for unwinding the suspension member from the rotary drum; and an impeding part connected with the rotary drum and affixed with an end of the suspension member, the impeding part being switchable between a first and a second position with respect to the rotary drum, the impeding part while remaining in the first position on the rotary drum being movable in unison with the rotary drum past the protrusion during rotation of the rotary drum in any of the first and second direction, and the impeding part when in the second position on the rotary drum being engageable with the protrusion to block rotation of the rotary drum in the second direction, the impeding part being switchable from the first position to the second position by a force exerted through the suspension member on the impeding part. | ||
