Shoelace fastener

摘要

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.

主权项

1. A shoelace fastener, comprising:
a main body; a reel, rotatably disposed in the main body, the reel being used for a wire winding thereon, two ends of the wire penetrating the main body respectively; a first elastic member, comprising two ends, one end of the first elastic member fixed on the main body, and an other end of the first elastic member fixed on the reel; a rotating member, comprising a base body, a clutch member and an operation member, one of the base body and the main body having a pawl portion, and an other one of the base body and the main body having a ratchet portion, the pawl portion engaging with the ratchet portion, the clutch member disposed between the base body and the operation member, the operation member moving between a first position and a second position with respect to the base body; a spindle, penetrating the rotating member, the spindle comprising a first end and a second end; wherein when the operation member is located in the first position, the clutch member engages with the first end of the spindle, the rotating member drives the spindle to rotate and the spindle drives the reel to rotate along a first direction and the first elastic member is rolled up tightly, when the operation member is located in the second position, the clutch member is away from the first end of the spindle, an elasticity of the first elastic member drives the reel to rotate along a second direction which is an opposite of the first direction, the reel drives the spindle to rotate along the second direction.
