Patent number: 8955199Abstract: A shoelace fastener includes a main body, a reel, a first elastic member, a rotating member and a spindle. When an operation member of the rotating member is located in a first position, a clutch member engages with the spindle. The rotating member drives the spindle to rotate and the spindle drives the reel to rotate along a first direction. When the operation member is located in a second position, the clutch member is away from the spindle. The first elastic member drives the reel to rotate and the reel drives the spindle to rotate along a second direction. Thereby, the tension of a wire is easy to be controlled. The reel doesn't turn in reverse randomly. As the operation member is raised up, it reminds a user that the reel is not adjusted to rotate unidirectionally yet.Type: GrantFiled: February 13, 2013Date of Patent: February 17, 2015Assignee: TZY Shenq Enterprise Co., Ltd.Inventor: Li-Chen Chang
