Abstract: A novel lacing device and an anti-reverse mechanism thereof are provided. The lacing device uses a novel swing arm-stop piece-gap mechanism as the anti-reverse mechanism, and the anti-reverse mechanism has double self-locking functions and a reverse deviation limiting function. Three effects are integrated, such that the lacing device using the novel anti-reverse mechanism not only has excellent hand feeling when the lace is tensioned, but also can effectively avoid the accidental loosening of the lace, and has excellent use reliability and durability.

Abstract: A spool, a tightening device with the spool, and a coupling method of the spool and a lace are provided. A first free end and a second free end of the lace are routed in subtended directions along a first routing path and a second routing path, respectively. The first routing path and the second routing path are designed in separate grade crossing structure. Even if the first free end and the second free end are routed simultaneously, they will not collide with each other. When the lace is knotted, there is no strict requirement for the length of a reserved tail of the lace. Even if the tail of the lace is left outside a housing, the tail of the lace can be wound onto the spool by rotating the spool, without affecting the normal operation of the tightening device. The method achieves easy, quick, and accurate lace coupling.
