| 发明名称 | Window shade and actuating system and operating method thereof | ||
| 摘要 | An actuating system for a window shade comprises a transmission axle, a spring drive unit operable to urge the transmission axle to rotate in a first direction for raising a shading structure of the window shade, and a control module including an arrester assembled around the transmission axle, and an operating cord operatively connectable with the transmission axle. The arrester has a locking state in which the arrester acts against the spring drive unit to block a rotational displacement of the transmission axle in the first direction, and an unlocking state in which rotation of drive axle is allowed. The operating cord is operable to turn the arrester from the locking state to the unlocking state and to drive rotation of the transmission axle in a second direction opposite to the first direction for lowering the shading structure of the window shade. | ||

| 主权项 | 1. An actuating system for a window shade, comprising: a transmission axle; a spring drive unit operable to urge the transmission axle to rotate in a first direction for raising a shading structure of the window shade; and a control module including an arrester assembled around the transmission axle, an operating cord operatively connectable with the transmission axle, and a release unit having an actuator operatively connected with the arrester, the actuator having an elongated shape extending along a lengthwise axis, and the operating cord extending through an interior of the actuator; the arrester having a locking state in which the arrester acts against the spring drive unit to block a rotational displacement of the transmission axle in the first direction, and an unlocking state in which rotation of the transmission axle is allowed; the operating cord being operable to turn the arrester from the locking state to the unlocking state and to drive rotation of the transmission axle in a second direction opposite to the first direction for lowering the shading structure of the window shade; and the actuator being operable to rotate about the lengthwise axis to drive the arrester to switch from the locking state to the unlocking state. | ||
