Publication number: 20160281421Abstract: A retarding device is used to retard movement of a cord of a window shade. The retarding device includes a support frame and a retarding unit. The support frame includes a base part having a base slot formed therethrough, and a side plate disposed at one side of the base part and having a securing portion formed therethrough. The retarding unit includes a cord retarding module, and a rod member disposed at the base slot. The cord retarding module has a mounting seat secured to the securing portion, and a retarding shaft rotatably supported on the mounting seat. The rod member and the retarding shaft are parallel to each other and extend in a longitudinal direction.Type: ApplicationFiled: July 14, 2015Publication date: September 29, 2016Applicant: Taicang Kingfu Plastic Manufacture Co., LTD.Inventor: Szu-Chang Huang

Patent number: 9260912Abstract: A cord-winding device for a Venetian blind includes: a first reel; a driving unit including a driving wheel and a spring-winding wheel; and a brake unit including a driven gear, a driving member, a ratchet wheel sleeved on the driving member, a plurality of friction members disposed between the driving member and the ratchet wheel, and at least pawl biased to engage the ratchet wheel. When the driven gear is driven by the first reel to rotate in a direction, rotation of the ratchet wheel is stopped by the pawl so that the driving member drives the friction members to rotate, and when the driven gear is driven by the driving wheel to rotate in an opposite direction, the driving member drives rotation of the friction members and, thus, the ratchet wheel.Type: GrantFiled: February 5, 2014Date of Patent: February 16, 2016Assignee: Taicang Kingfu Plastic Manufacture Co., Ltd.Inventor: Szu-Chang Huang
